Description

Technical Field

[0001] This utility model demonstrates a rail-type lifting system, belonging to the technical field of rail-type lifting systems. Background Technology

[0002] The rail-mounted lifting system, also known as a ceiling-mounted patient transfer machine, is primarily used to address the mobility, toileting, and bathing needs of the elderly, those with mobility issues, and those unable to walk. It is widely applicable in hospitals, nursing homes, rehabilitation centers, and homes. The transfer machine is mainly a nursing device designed to assist disabled individuals with barrier-free movement, used for short-distance relocation and rehabilitation care for disabled individuals or patients.

[0003] A detachable ceiling track moving machine typically includes a track, a trolley, a main unit, and a boom. The track is laid on the indoor ceiling, and the trolley is slidably connected to the track so that the trolley can slide along the track. The main unit is connected to the trolley and is used to control the raising and lowering of the boom. In traditional detachable ceiling track moving machines, the trolley and the main unit are usually fixedly connected. However, when the main unit malfunctions and needs to be repaired or replaced, the disassembly of the main unit and the trolley is quite complicated, which greatly increases the difficulty of installing and disassembling the main unit.

[0004] In existing detachable overhead rail transfer machines, the main unit is suspended from the trolley via a detachable coupling device. The detachable coupling device includes a pair of latch hooks and a pair of movable latches. However, in the existing technology, the two movable latches are independent of each other, which can easily lead to a situation where one movable latch engages with the latch hook while the other movable latch has not yet engaged with the latch hook. In this state, the user needs to disassemble the trolley and the main unit and reinstall them, which can easily result in repeated installation and increase the difficulty of installing the main unit and the trolley. Utility Model Content

[0005] The purpose of this invention is to solve the problem that during installation, only one movable latch may engage with the latch hook, which may lead to the need for reinstallation. To address this, a track-type lifting system is provided, in which two movable latches rotate synchronously, ensuring that both latch pins can engage with the latch hook simultaneously.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A track-type lifting system includes a track mechanism and a lifting mechanism. The track mechanism includes a track and a trolley that moves along the track. The lifting mechanism is suspended from the trolley by a detachable coupling device. The detachable coupling device includes a movable latch and a latch hook. One of the latch hook and the movable latch is arranged in a pair on the lifting mechanism, and the other is arranged in a pair on the trolley. The movable latch includes a pivot bracket and a latch pin connected to the pivot bracket. The two pivot brackets can be operably rotated to engage or disengage the latch pin from the latch hook. A transmission mechanism is provided between the two pivot brackets, and the rotation of one pivot bracket drives the other pivot bracket to rotate synchronously through the transmission mechanism.

[0008] The beneficial effects of using this utility model are:

[0009] In this invention, a transmission mechanism is provided between the two pivot supports. The two pivot supports rotate synchronously through the transmission mechanism. That is, when one pivot support is pushed to rotate, the other pivot support is operated to rotate. The first pivot support drives the second pivot support to rotate through the transmission mechanism, and the rotation angles of the two pivot supports are the same. Therefore, when one pivot support is rotated to engage or disengage the latch pin from the latch hook, the other pivot support will be simultaneously rotated under the action of the transmission mechanism to engage or disengage the latch pin from the latch hook. In other words, the two pivot supports can simultaneously engage or disengage the two latch pins from the latch hook. To ensure the reliability of the engagement between the movable latch and the latch hook, and to prevent the lifting mechanism from detaching due to incomplete engagement of one latch pin and latch hook, the connection between the lifting mechanism and the trolley is made safer and more reliable, thus improving the safety of the lifting mechanism in use. Furthermore, during the installation and disassembly of the lifting mechanism, the user can push one of the pivot brackets to engage and disengage both movable latches and latch hooks, reducing the difficulty of installation and disassembly and avoiding repeated rotation of the pivot bracket during installation or disassembly. This makes the installation of the lifting mechanism and the trolley smoother and improves the user experience.

[0010] Preferably, the transmission mechanism includes two rotating parts arranged in pairs and a transmission component that drives the two rotating parts together. The two rotating parts are coaxially mounted and fixedly connected to two pivot supports. By adopting the aforementioned technical solution, the coaxial mounting and fixed connection between the rotating parts and the pivot supports ensures that the rotating parts and pivot supports rotate synchronously. The two rotating parts achieve synchronous and opposite rotation through the transmission component, and the rotational state of the two rotating parts can be directly transmitted to the two pivot supports, thereby achieving synchronous and opposite rotation of the two pivot supports.

[0011] Preferably, the transmission component is a toothed part disposed on the surface of the rotating component, and the two rotating components are kept in mesh by the teeth to achieve synchronous and opposite rotation. Adopting the aforementioned technical solution, where the two rotating components are gears, and synchronous and opposite rotation is achieved by the meshing of the two gears, simplifies the overall structure of the transmission mechanism, reduces the space occupied, and makes it suitable for more compact installation spaces. Furthermore, the direct meshing of the two rotating components reduces the number of transmission parts between them, reducing energy loss during power transmission. The force required for the user to rotate the pivot bracket is smaller, which helps improve the user experience. Secondly, the direct meshing of the two rotating components reduces the possibility of transmission mechanism failure, making the transmission mechanism more stable and reliable, helping to extend the service life of the transmission mechanism, and also improving the accuracy of power transmission, ensuring that the rotation angles of the two pivot brackets remain consistent, and making the engagement of the movable latch and the latch hook safer and more reliable.

[0012] Preferably, the teeth are arranged in a fan shape and located on opposite sides of the two rotating parts. Using the aforementioned technical solution, since the rotation angle during the engagement and disengagement of the latch hook and latch pin driven by the pivot bracket is small, fewer teeth are needed during rotation. Arranging the teeth in a fan shape eliminates other unnecessary teeth, improves the utilization rate of the teeth, and further reduces the space occupied by the transmission mechanism.

[0013] Preferably, the transmission component is a transmission belt that is interference-fitted with the rotating component, wherein the rotation of one rotating component drives the other rotating component to rotate in the opposite direction via the transmission belt. By employing the aforementioned technical solution, the transmission belt simultaneously drives the rotation of two rotating components, effectively reducing the difficulty of installing and disassembling the transmission belt and rotating components, helping to reduce the maintenance difficulty of the transmission mechanism, and improving the efficiency of installing and replacing the transmission belt.

[0014] Preferably, the transmission belt is wound in a figure-eight pattern around the two rotating parts.

[0015] Preferably, the transmission component is a linkage assembly, in which the rotation of one rotating component drives the other rotating component to rotate in the opposite direction via the linkage assembly.

[0016] Preferably, the linkage assembly includes two fixed rods radially distributed along the rotating member and a movable rod with both ends hinged to the two fixed rods respectively. The two fixed rods are fixed to the two rotating members respectively, with one fixed rod located on the upper side of the rotating member and the other fixed rod located on the lower side of the rotating member.

[0017] Preferably, one of the rotating parts drives the other rotating part to rotate synchronously and in the same direction through a transmission part.

[0018] Preferably, the pivot bracket has a stop portion, and a gap region is formed between the stop portions of the two pivot brackets. The detachable coupling device also includes a locking element that can be operatively switched between a locked position and an unlocked position. When the latch post and latch hook are engaged, the gap region provides a locked position to allow the locking element to enter. The two stops are abutted by the locking element to restrict the rotation of the pivot bracket. When the locking element is in the unlocked position, it releases its abutment against the stops. Using the aforementioned technical solution, after the locking element is in the locked position, it simultaneously abuts against the two stops, thereby restricting the rotation of the two pivot supports. This ensures that the latch pin remains locked to the latch hook. Therefore, even if a greater external force pushes the pivot support, the pivot support will not rotate, preventing the latch pin from disengaging from the latch hook and avoiding the phenomenon of the latch pin and latch hook being unlocked at will. This ensures that the latch pin and latch hook maintain a stable and reliable connection, making the lifting system safer and more reliable to use. In addition, the cooperation of the first reset member and the locking element provides double protection for the pivot support, ensuring that the engagement between the latch pin and latch hook remains stable and reliable, significantly reducing the possibility of the latch pin disengaging from the latch hook at will, and ensuring the connection between the lifting mechanism and the trolley. The connection is safer and more reliable, which helps to improve the safety of the lifting system. Secondly, during the unlocking process of the latch column and latch hook, the locking element is first operated to the unlock position so that the locking element releases its contact with the stop, allowing the pivot bracket to rotate normally. This allows the latch column and latch hook to separate from each other, realizing the disassembly of the lifting mechanism and the trolley. The overall structure and assembly method of the locking element, the first reset element and the movable latch in this utility model are relatively simple. At the same time, the installation and disassembly process of the latch hook and the movable latch can be completed by operating the locking element and the pivot bracket in sequence. That is, the whole operation process is relatively simple, which can realize the rapid disassembly and installation of the lifting mechanism and significantly improve the disassembly and installation efficiency of the lifting mechanism.

[0019] Preferably, the sliding direction of the locking element is parallel to the rotation axis of the pivot bracket, and the locking element switches between the locked position and the unlocked position by sliding, with the locking element in the unlocked position disengaging from the interval area.

[0020] Preferably, the locking element is elastically loaded by the second reset member and maintains its tendency to move towards the locked position. Using the aforementioned technical solution, the second reset member can automatically reset the locking element to the locked position without manual operation. It also ensures that after the latch pin and latch hook engage, the locking element can reset to the locked position, thereby restricting the pivot bracket and preventing situations where locking is incomplete due to forgetting to engage. This ensures that the locking element can perform its locking function, making the locking of the latch pin and latch hook safer and more reliable, thus improving the safety of the lifting system.

[0021] Preferably, the locking element is fixedly connected to a first operating member, the trolley includes a housing, the locking element is located within the housing, and a second reset member is constrained between the first operating member and the housing. Using the aforementioned technical solution, the user can control the locking element to switch between the locked and unlocked positions via the first operating member. The first operating member makes applying force simpler and easier for the user, significantly reducing the difficulty of operation.

[0022] Preferably, the detachable coupling device further includes a limiting element. When the locking element is in the unlocked position, the limiting element enters the movement path of the locking element to restrict the locking element from moving to the locked position. Using the aforementioned technical solution, since the pivot bracket is elastically loaded by the first reset member, the pivot bracket automatically rotates towards the position where it engages with the latch hook. Therefore, when the pivot bracket loses external force, space is provided between the two stops for the locking element to reach the locked position. The limiting element restricts the locking element, preventing it from returning to the locked position even without rotating the pivot bracket. This ensures the pivot bracket can rotate freely and smoothly, effectively preventing the need for repeated operations to disengage the locking element from the locked position, and significantly simplifying the unlocking process of the movable latch and latch hook.

[0023] Preferably, the limiting element includes a blocking position that restricts the movement of the locking element towards the locking position and a clearance position that releases the restriction on the locking element. The limiting element is elastically loaded by the third reset member and maintains its tendency to move towards the blocking position. The locking element in the locking position restricts the limiting element to the clearance position. Using the aforementioned technical solution, when the locking element is operated to the unlock position, the limiting element will automatically move to the blocking position under the action of the third reset member. This allows the locking element to be promptly restricted to the unlock position without manual operation, ensuring that the limiting element can reliably restrict the locking element. It also eliminates the need for manual operation and improves the interoperability of the detachable coupling device.

[0024] Preferably, the limiting element is rotatably connected to the trolley, and a first protrusion is provided on the outer periphery of the limiting element. When in the blocking position, the first protrusion is at least partially within the movement path of the locking element to restrict the movement of the locking element to the locking position. When in the locking position, the locking element abuts against the first protrusion to restrict the rotation of the limiting element. By adopting the aforementioned technical solution, the rotatable setting of the limiting element can reduce the space occupied by the movement path of the limiting element, making the assembly of the limiting element and the locking element more compact.

[0025] Preferably, the locking element further includes a pre-locked position, which is between the unlocked and locked positions. The pivot bracket rotates in the direction of disengaging from the latch hook, causing the limiting element to rotate to the clearance position, and placing the pivot bracket at least partially within the movement path of the locking element. The end face of the pivot bracket in the sliding direction of the locking element abuts against the locking element, restricting the locking element to the pre-locked position. The locking element in the pre-locked position restricts the limiting element to the clearance position. Using the aforementioned technical solution, the movable latch can simultaneously reset the limiting element to the clearance position during the unlocking process, thereby releasing the limitation of the limiting element on the locking element. This allows the locking element to automatically reset to the locked position and restrict the limiting element to the clearance position. Afterwards, when the pivot bracket rotates in the direction of engaging with the latch hook, the limiting element remains in the clearance position under the restriction of the locking element. After the latch pin engages with the latch hook, the limiting element can smoothly move from the unlocked position to the locked position. That is, during the entire unlocking process, the movement of the limiting element does not require separate manual operation, effectively simplifying the operation steps of the detachable coupling device, and allowing the lifting mechanism and the trolley to... The installation and disassembly are simpler and faster, which helps to improve the efficiency of the lifting mechanism and its installation and disassembly. In addition, it can also eliminate the parts used to operate the limit element, simplifying the structure of the limit element, reducing the installation difficulty of the limit element, and reducing the space occupied by the limit element. Secondly, after the pivot bracket resets the limit element to the avoidance position, the locking element will slide to the locking position and abut against the stop at the pre-lock position. At this time, the locking element restricts the limit element. During the subsequent rotation of the pivot bracket, the limit element is still kept in the avoidance position by the locking element. After the pivot bracket is reset, the locking element can automatically reset to the locking position, thus completing the restriction of the pivot bracket.

[0026] Preferably, the limiting block is provided with a second protrusion. In the blocking position, the second protrusion is at least partially within the rotation path of the pivot bracket. The pivot bracket rotates in the direction of disengaging from the latch hook to push the second protrusion, thereby causing the limiting element to rotate towards the avoidance position.

[0027] Preferably, the limiting element is fixedly connected to a second operating member, which can be operated to move the limiting element to the avoidance position.

[0028] Preferably, the pivot bracket includes a first locking plate and a second locking plate, with a latch pin fixed between the first and second locking plates. A stop is located on one side of the two first locking plates opposite each other, and the two second locking plates are connected by a transmission mechanism. With the aforementioned technical solution, the latch pin is positioned between the first and second locking plates. After the latch pin engages with the latch hook, the force-bearing position of the latch bracket is also between the first and second locking plates. This makes the force on the pivot bracket more balanced, helps reduce the shear force on the pivot bracket, reduces the possibility of deformation or breakage of the pivot bracket, helps extend the service life of the pivot bracket, and also improves the safety of the lifting system. Furthermore, the stop and transmission mechanism are respectively located on the first and second locking plates, which can effectively avoid the possibility of interference between the locking element and the transmission mechanism.

[0029] Preferably, the trolley or lifting mechanism is equipped with a sensor for sensing the position of the pivot support. The sensor is electrically connected to an alarm. The pivot support includes an engagement position where the latch pin engages with the latch hook and a disengagement position where the latch pin disengages from the latch hook. The pivot support is elastically loaded by a first reset member and tends to rotate toward the engagement position. When the pivot support is in the engagement and disengagement positions, the sensor deactivates the alarm. When the pivot support is between the engagement and disengagement positions, the sensor triggers the alarm. Using the aforementioned technical solution, after the latching column and latching hook are stably engaged, the pivot bracket is in the engaged position. At this time, the lifting mechanism and the trolley are stably connected and are unlikely to detach, so no alarm is needed. When the latching column and latching hook are unlocked, the pivot bracket is in the disengaged position, and no alarm is needed for unlocking. Since the pivot bracket is elastically loaded by the first reset member, it will automatically reset to the engaged position when no force is applied. However, when the latching column and latching hook are not fully engaged, the latching hook will abut against the latching column, thus preventing the pivot bracket from resetting to the engaged position. At this time, the pivot bracket will remain between the engaged and disengaged positions. In this state, the latching column and latching hook are not reliably engaged. To prevent users from mistakenly believing that the latching column and latching hook have been engaged, the sensor needs to trigger the alarm to remind the user that the latching column and latching hook are not fully engaged and need to be reinstalled to ensure that the latching column and latching hook can maintain a reliable engagement, further improving the safety of the lifting system.

[0030] Preferably, the pivot bracket is provided with a trigger. When the pivot bracket is in the engaged position, the trigger is completely within the sensing range of the sensor. When the pivot bracket is in the disengaged position, the trigger is completely out of the sensing range of the sensor. Between the engaged and disengaged positions, the trigger is partially within the sensing range of the sensor.

[0031] Preferably, the sensor is mounted on the lifting mechanism, and the movable latch includes a guide pin connected to the pivot bracket, a trigger element is mounted on the end of the guide pin, and the guide pin and the latch post are coaxially arranged. By adopting the aforementioned technical solution, it is ensured that the movement paths of the latch post and the guide pin are the same, so that changes in the position of the guide pin can accurately reflect changes in the position of the latch post, which helps to improve the accuracy and reliability of the sensor's position sensing of the pivot bracket.

[0032] Preferably, each pivot bracket is provided with two guide pins, which are respectively located on the extension lines of both ends of the latch post. At least one guide pin in each pivot bracket is equipped with a trigger element, and the number of sensors corresponds to the number of trigger elements. Using the aforementioned technical solution, both pivot brackets are equipped with trigger elements, and each trigger element also corresponds to a sensor. When one sensor malfunctions, the other can still determine the position of the pivot bracket, effectively extending the sensing time of the sensor on the pivot bracket and further improving the safety of the lifting system.

[0033] Preferably, the two pivot brackets are brought close to each other, causing the latch pin to disengage from the latch hook. The sensor is tilted downwards in the unlocking direction of the pivot bracket. When the pivot bracket is in the engaged position, the highest point of the sensor is directly in front of the trigger.

Therefore, they should not be construed as limitations on this utility model.

[0057] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0058] Example 1:

[0059] like Figures 1 to 16 As shown in the figure, this embodiment illustrates a track 3 mechanism lifting system, including a track 3 mechanism and a lifting mechanism 4. The track 3 mechanism includes a track 3 and a trolley 1 that moves along the track 3. The lifting mechanism 4 includes a main unit 41 and a boom 42. A roller 15 is rotatably connected to the top of the trolley 1. The bottom of the track 3 is provided with a slot for the trolley 1 to extend into. The edge of the slot forms a slide rail for the roller 15 to slide. The roller 15 slides along the slide rail to achieve a sliding connection between the trolley 1 and the track 3. A winch is provided inside the main unit 41. A traction belt is wound on the winch. The traction end of the traction belt extends from the bottom end of the main unit 41 and is connected to the boom 42.

[0060] like Figure 2 As shown, in this embodiment, the lifting mechanism 4 is detachably connected to the trolley 1 via a detachable coupling device. The detachable coupling device includes a pair of latch hooks 21 mounted on the top of the lifting mechanism 4 and a pair of movable latches mounted on the trolley 1. The movable latches include a pivot bracket 12 hinged to the trolley 1 and a latch pin 125 connected to the pivot bracket 12. The pivot bracket 12 includes an engagement position for engaging the latch pin 125 with the latch hook 21 and a disengagement position for disengaging the latch pin 125 from the latch hook 21. The two pivot brackets 12 can be operably rotated in opposite directions to switch between the engagement position and the disengagement position. A transmission mechanism is provided between the two pivot brackets 12, and the rotation of one pivot bracket 12 drives the other pivot bracket 12 to rotate synchronously and in the opposite direction through the transmission mechanism.

[0061] In this embodiment, a transmission mechanism is provided between the two pivot supports 12. The two pivot supports 12 rotate synchronously through the transmission mechanism. That is, when one pivot support 12 is pushed to rotate, the other pivot support 12 is operated to rotate. The first pivot support 12 drives the other pivot support 12 to rotate through the transmission mechanism, and the rotation angles of the two pivot supports 12 are the same. Therefore, when one pivot support 12 is rotated to engage or disengage the latch pin 125 from the latch hook 21, the other pivot support 12 will be simultaneously rotated under the action of the transmission mechanism to engage or disengage the latch pin 125 from the latch hook 21. In other words, the two pivot supports 12 can simultaneously engage the two latch pins 125 with the latch hook 21. Alternatively, it can disengage to ensure the reliability of the engagement between the movable latch and the latch hook 21, preventing the lifting mechanism 4 from falling off due to the incomplete engagement of one latch pin 125 with the latch hook 21. This makes the connection between the lifting mechanism 4 and the trolley 1 safer and more reliable, thus improving the safety of the lifting mechanism 4. In addition, during the installation and disassembly of the lifting mechanism 4, the user can push one of the pivot brackets 12 to engage and disengage the two movable latches with the latch hook 21. This helps reduce the difficulty of installing and disassembling the lifting mechanism 4 and avoids the phenomenon of repeatedly rotating the pivot bracket 12 during installation or disassembly. This makes the installation of the lifting mechanism 4 and the trolley 1 smoother and helps improve the user experience.

[0062] like Figure 2 As shown, the transmission mechanism in this embodiment includes two rotating parts 1221 arranged in pairs and a transmission component that drives the two rotating parts 1221 to rotate. The two rotating parts 1221 are respectively fixed to two pivot brackets 12, and the rotating parts 1221 and the pivot brackets 12 connected to them are coaxially arranged, which can ensure that the rotating parts and the pivot brackets 12 can rotate synchronously. The two rotating parts 1221 achieve synchronous and opposite rotation through the transmission component. The rotation state of the two rotating parts 1221 can be directly transmitted to the two pivot brackets 12, thereby achieving synchronous and opposite rotation of the two pivot brackets 12.

[0063] In this embodiment, the transmission component is a tooth 1222 disposed on the surface of the rotating component 1221, i.e., the rotating component 1221 is a gear. The two rotating components 1221 achieve synchronous and opposite rotation through the meshing of the teeth 1222. In addition, since the angle of rotation for the engagement and disengagement of the latch hook 21 and the latch pin 125 driven by the pivot bracket 12 is small, the actual number of teeth 1222 participating in the meshing is small during the rotation of the pivot bracket 12. Therefore, in this embodiment, the teeth 1222 are arranged in a fan shape, i.e., the rotating component 1221 is a sector gear, and the angle of the distribution of the teeth 1222 is basically the same as the maximum rotation angle of the pivot bracket 12, thereby ensuring that all teeth 1222 can participate in the meshing during the rotation of the pivot bracket 12, improving the utilization rate of the teeth 1222; in addition, setting the teeth 1222 in a fan shape can By eliminating other unnecessary teeth 1222, the space occupied by the transmission mechanism can be further reduced, making the overall structure of the movable latch more compact and suitable for more compact installation spaces, thus helping to reduce the size of the trolley 1. Secondly, the direct engagement of the two rotating parts 1221 reduces the number of transmission components between the two rotating parts 1221, reducing energy loss during power transmission. The force required for the user to rotate the pivot bracket 12 is smaller, which helps to improve the user experience. In addition, the direct engagement of the two rotating parts 1221 can reduce the possibility of transmission mechanism failure, making the transmission mechanism more stable and reliable, helping to extend the service life of the transmission mechanism, and also improving the accuracy of power transmission, ensuring that the rotation angle of the two pivot brackets 12 is consistent, making the engagement of the movable latch and the latch hook 21 safer and more reliable.

[0064] In this embodiment, the lifting mechanism 4, through a detachable coupling device, also includes a locking element 13 disposed on the trolley 1. The movable latch is also connected to a first reset member 128. The movable latch is elastically loaded by the first reset member 128 to maintain the engagement tendency of the latch post 125 and the latch hook 21. The pivot bracket 12 has a stop portion 124, and a gap region is formed between the stop portions 124 of the two pivot brackets 12. The locking element 13 can be operably switched between a locked position and an unlocked position. When the pivot bracket 12 is in the engaged position, the gap region provides a locked position and allows the locking element 13 to enter. When the locking element 13 is in the locked position, the two stop portions 124 are abutted by the locking element 13 to restrict the rotation of the pivot bracket 12. When the locking element 13 is in the unlocked position, the locking element 13 releases the abutment of the stop portion 124. At this time, the pivot bracket 12 loses the restriction of the locking element 13 and can rotate freely between the engaged position and the disengaged position, thereby realizing the engagement and disengagement of the latch post 125 and the latch hook 21.

[0065] In this embodiment of the invention, the lifting mechanism 4 is suspended from the trolley 1 by a detachable coupling device. The detachable coupling device includes a latch hook 21, a movable latch, and a locking element 13. The movable latch includes a pivot bracket 12 and a latch post 125. A gap area is formed between the stops 124 of the two pivot brackets 12. The locking element 13 has a locked position and an unlocked position. When the latch post 125 is engaged with the latch hook 21, the gap area provides space for the locking element 13 to enter, so that the locking element 13 can move to the locked position. After the locking element 13 is in the locked position, the locking element 13 is simultaneously engaged with the two stops. The stop 124 abuts against each other, thereby restricting the rotation of the two pivot brackets 12, and ensuring that the latch pin 125 can remain locked with the latch hook 21. Therefore, even if a greater external force pushes the pivot bracket 12, the pivot bracket 12 will not disengage from the locked position, avoiding the phenomenon of the latch pin 125 being unlocked at will. This ensures that the latch pin 125 and the latch hook 21 can maintain a stable and reliable connection, making the use of the shifting machine safer and more reliable. In addition, the movable latch is elastically loaded by the first reset member 128, thereby maintaining the engagement tendency of the latch pin 125 and the latch hook 21. Therefore, under the action of the first reset member 128, there is no significant change in the engagement. Under external force, the pivot bracket 12 will not rotate arbitrarily, reducing the possibility of the latch pin 125 disengaging from the latch hook 21. Therefore, the cooperation of the first reset member 128 and the locking element 13 provides double protection for the pivot bracket 12, ensuring that the engagement between the latch pin 125 and the latch hook 21 remains stable and reliable, significantly reducing the possibility of the latch pin 125 disengaging from the latch hook 21 arbitrarily, making the connection between the lifting mechanism 4 and the trolley 1 safer and more reliable, and helping to improve the safety of the lifting system. Secondly, during the unlocking process of the latch pin 125 and the latch hook 21, the locking element 13 is first operated to the unlock position so that the lock... The locking element 13 releases its contact with the stop part 124, allowing the pivot bracket 12 to rotate normally. This allows the latch pin 125 to separate from the latch hook 21, thus enabling the disassembly of the lifting mechanism 4 from the trolley 1. In this embodiment, the overall structure and assembly of the locking element 13, the first reset element 128, and the movable latch are relatively simple. Furthermore, the installation and disassembly of the latch hook 21 and the movable latch can be completed by operating the locking element 13 and the pivot bracket 12 in sequence. In other words, the entire operation process is relatively simple, enabling the rapid disassembly and installation of the lifting mechanism 4 and significantly improving the efficiency of disassembly and installation of the lifting mechanism 4.

[0066] It should be noted that in this embodiment, the two latch hooks 21 are arranged opposite to each other, and the two pivot brackets 12 rotate in opposite directions from the engagement position to the disengagement position. That is, when the two pivot brackets 12 rotate towards each other, they move closer to each other, which allows the latch pin 125 to disengage from the latch hook 21, thus separating the latch pin 125 from the latch hook 21. Correspondingly, when the two pivot brackets 12 rotate away from each other, they move further away from each other, which allows the latch pin 125 to engage with the latch hook 21, thus locking the lifting mechanism 4 and the trolley 1. In addition, to avoid relative displacement of the two latch hooks 21, in this embodiment, the two latch hooks 21 are a single unit.

[0067] It is understandable that in other embodiments, the two latch hooks 21 can also be arranged in opposite directions. In this case, the two pivot supports 12 rotate in opposite directions from the engagement position to the disengagement position. That is, when the two pivot supports 12 rotate in opposite directions, the two pivot supports 12 move away from each other, which can make the latch pin 125 disengage from the latch hook 21 and realize the separation of the latch pin 125 from the latch hook 21. Correspondingly, when the two pivot supports 12 rotate towards each other, the two pivot supports 12 move closer to each other, which can make the latch pin 125 engage with the latch hook 21 and realize the locking of the lifting mechanism 4 and the trolley 1.

[0068] Other examples Figure 4 As shown, in this embodiment, the trolley 1 is provided with two first reset members 128, which correspond to two pivot brackets 12. The first reset member 128 is a tension spring. One end of the first reset member 128 is hooked inside the trolley 1, and the other end is connected to the side of the pivot bracket 12 away from the stop part 124. Of course, it can be understood that in other embodiments, the two pivot brackets 12 may also share a first reset member 128. The first reset member 128 is located on the upper side of the two pivot brackets 12, and the two ends of the first reset member 128 are respectively connected to the opposite sides of the two pivot brackets 12. After the first reset member 128 is connected to the two pivot brackets 12, it is in a stretched state, which can make the two pivot brackets 12 have a tendency to rotate in opposite directions.

[0069] like Figures 2 to 4As shown, in this embodiment, the trolley 1 includes a housing 11, a locking element 13 fixedly connected to a first operating member 131, the locking element 13 being inside the housing 11, and the first operating member 131 being outside the housing 11. The locking element 13 is elastically loaded with a second reset member 132, which is a compression spring. The second reset member 132 is confined between the first operating member 131 and the housing 11. The user presses the first operating member 131 to move the locking element 13 from the locked position to the unlocked position. The sliding direction 133 of the locking element 13 is parallel to the rotation axis 1231 of the pivot bracket 12. When the locking element 13 is in the unlocked position, it disengages from the gap between the two stops 124. After the user releases the first operating member 131, the second reset member 132 acts on the first operating member 131. The first operating component 131 causes the locking element 13 to automatically reset to its initial position. The first operating component 131 controls the locking element 13 to switch between the locked and unlocked positions, making it easier and simpler for the user to apply force and significantly reducing the difficulty of operation. In addition, the second reset component 132 can automatically reset the locking element 13 to the locked position without manual operation. It also ensures that after the latch column 125 and the latch hook 21 are engaged, the locking element 13 can be reset to the locked position, thereby restricting the pivot bracket 12 and preventing the situation where the locking is not in place due to forgetting. This ensures that the locking element 13 can play a locking role, making the locking of the latch column 125 and the latch hook 21 safer and more reliable, and helping to improve the safety of the lifting system.

[0070] like Figure 4 and Figure 5 As shown, in this embodiment, the pivot bracket 12 is rotatably connected to the trolley 1 via a pivot shaft 123. The pivot shaft 123 is located at the upper end of the pivot bracket 12, and the latching pin 125 is located at the lower end of the pivot bracket 12. During the rotation of the pivot bracket 12, the latching pin 125 rotates around the pivot shaft 123 along with the pivot bracket 12. The rotation directions of the two pivot brackets 12 from the engaged position to the disengaged position are opposite. For details, please refer to [reference needed]. Figure 4 The left pivot bracket 12 rotates counterclockwise from the engaged position to the disengaged position, and the right pivot bracket 12 rotates clockwise from the engaged position to the disengaged position. The stop portion 124 is provided on the opposite side of the two pivot brackets 12. In the height direction, the stop portion 124 is at least partially lower than the rotation axis 1231 of the pivot bracket 12. The opposite sides of the two stop portions 124 are abutting surfaces 1241. The locking element 13 is in the shape of a cuboid. When the locking element 13 is in the locked position, the side walls 134 on both sides of the locking element 13 abut against the abutting surfaces 1241 of the two stop portions 124, thereby restricting the rotation of the two pivot brackets 12.

[0071] like Figures 4 to 9As shown, the detachable coupling device in this embodiment further includes a limiting element 14, which is located between the two pivot supports 12. In the height direction, the limiting element 14 is located below the locking element 13. The limiting element 14 has a blocking position and an avoidance position. The limiting element 14 is connected to a third reset member 143. The limiting element 14 is elastically loaded by the third reset member 143 and maintains a tendency to move towards the blocking position. (Refer to...) Figure 4 and Figure 5 As shown, when the locking element 13 is in the locked position, it is directly above the limiting element 14, and the locking element 13 abuts against the limiting element 14, restricting the limiting element 14 to a clearance position. When the locking element 13 moves to the unlocked position, it releases the restriction on the limiting element 14. The limiting element 14 automatically resets to the blocking position under the action of the third reset member 143. At this time, the limiting element 14 enters the movement path of the locking element 13, and abuts against the locking element 13, thus restricting the locking element 13 from resetting to its initial position. Since the pivot bracket 12 is elastically loaded by the first reset member 128, the pivot bracket 12 will automatically rotate toward the position where it engages with the latch hook 21. Therefore, when the pivot bracket 12 loses external force, the two stop portions 124... This provides space for the locking element 13 to reach the locking position, while the limiting element 14 restricts the locking element 13. Even without rotating the pivot bracket 12, the locking element 13 cannot return to the locking position, ensuring that the pivot bracket 12 can rotate freely and smoothly. This effectively prevents the locking element 13 from disengaging from the locking position and significantly simplifies the unlocking process of the movable latch and latch hook 21. In addition, when the locking element 13 is operated to the unlock position, the limiting element 14 will automatically move to the blocking position under the action of the third reset member 143. Without manual operation, the locking element 13 can be restricted to the unlock position in time, ensuring that the limiting element 14 can reliably restrict the locking element 13. At the same time, it can also save manual operation and improve the linkage of the detachable coupling device.

[0072] In this embodiment, the limiting element 14 is rotatably connected to the trolley 1, and the third reset element 143 is a torsion spring. One end of the torsion spring acts on the trolley 1, and the other end acts on the limiting element 14. The outer periphery of the limiting element 14 is provided with a first protrusion 141. When in the blocking position, the first protrusion 141 is at least partially in the movement path of the locking element 13 to restrict the locking element 13 from moving to the locking position. When in the locking position, the locking element 13 abuts against the first protrusion 141 to restrict the rotation of the limiting element 14. The rotatable setting of the limiting element 14 can reduce the space occupied by the movement path of the limiting element 14, so that the assembly of the limiting element 14 and the locking element 13 can be more compact.

[0073] like Figure 5As shown, when the locking element 13 is in the locked position, the locking element 13 is at least partially located directly above the first protrusion 141. Under the action of the third reset element 143, the limiting element 14 will cause the first protrusion 141 to rotate upwards. The first protrusion 141 will abut against the bottom wall 135 of the limiting element 14 and block the rotation of the limiting element 14, thereby restricting the limiting element 14 to an avoidance position. (Refer to...) Figure 6 and Figure 7 As shown, when the locking element 13 slides to the unlock position, the locking element 13 disengages from directly above the first protrusion 141, that is, the locking element 13 releases its restriction on the limiting element 14. At this time, the limiting element 14 will automatically rotate to the blocking position under the action of the third reset member 143. At this time, the first protrusion 141 will enter the movement path of the locking element 13, that is, the first protrusion 141 is at least partially in front of the locking element 13. After the user releases the first operating member 131, the locking element 13 will automatically move to the locking position, and the front wall 136 of the locking element 13 will abut against the first protrusion 141, thereby remaining in the unlock position.

[0074] It is understandable that in other embodiments, the limiting element 14 may also be slidably connected to the trolley 1, and the corresponding third reset member 143 is a compression spring. The limiting element 14 is fixedly connected to the second operating member. When the locking element 13 slides to the unlock position, the limiting element 14 will automatically reset to the blocking position under the action of the third reset member 143. When it is necessary to release the restriction of the limiting element 14 on the locking element 13, the user can drive the limiting element 14 to move to the avoidance position through the second operating member. After the limiting element 14 leaves the blocking position, the locking element 13 will automatically slide to the locking position under the action of the second reset member 132.

[0075] like Figure 8 and Figure 9As shown, in this embodiment, the locking element 13 also includes a pre-lock position, which is between the unlock position and the locked position. The outer periphery of the limiting element 14 is also provided with a second protrusion 142. When the limiting element 14 is in the blocking position, the second protrusion 142 is at least partially within the rotation path of the pivot bracket 12. During the rotation of the pivot bracket 12 towards the disengaged position, the pivot bracket 12 pushes the second protrusion 142 to drive the limiting element 14 back to the clearance position. When the user presses the first operating member 131, the locking element 13 is directly pushed to the unlock position. At this time, the lock... When the locking element 13 releases the restriction on the pivot bracket 12 and the limiting element 14, the pivot bracket 12 can rotate freely between the engaged and disengaged positions. The limiting element 14 automatically rotates to the blocking position under the action of the third reset element 143. After the user releases the first operating element 131, the locking element 13, under the action of the second reset element 132, abuts against the first protrusion 141 of the limiting element 14, thus being restricted to the unlocked position. During the rotation of the pivot bracket 12 towards the disengaged position, the side of the pivot bracket 12 contacts the second protrusion 142. As the pivot bracket 12 rotates continuously, it pushes the limiting element 14 to rotate towards the avoidance position via the second protrusion 142. When the pivot bracket 12 rotates to the unlocked position, it drives the limiting element 14 to reset to the avoidance position. At this time, the first protrusion 141 avoids the sliding path of the locking element 13, so the first protrusion 141 releases the restriction on the locking element 13. Under the action of the second reset member 132, the locking element 13 continues to slide towards the initial position. However, since the pivot bracket 12 has already rotated to the unlocked position, that is, the stop of the pivot bracket 12... The stop 124 occupies the space of the locking element 13 in the locking position. Therefore, the front wall 136 of the locking element 13 will abut against the end face 1242 of the stop 124 in the sliding direction 133 of the locking element 13. The locking element 13 still cannot be reset to the initial position. At this time, the locking element 13 stays in the pre-lock position under the obstruction of the stop 124. When the locking element 13 is in the pre-lock position, the locking element 13 is above the first protrusion 141. That is, at this time, the locking element 13 will also block the rotation of the first protrusion 141, thereby restricting the limiting element 14 to the avoidance position.When the user releases the external force applied to the pivot bracket 12, the first reset member 128 pulls the pivot bracket 12, causing it to automatically rotate towards the engagement position until it returns to the engagement position. During the reset process, the force on the second protrusion 142 is gradually released, but the limiting element 14 remains in the avoidance position, which restricts the locking element 13. After the pivot bracket 12 returns to the locked position, the stop 124 separates from the locking element 13, and the locking element 13, under the action of the second reset member 132, enters the interval area and reaches the locked position, thus restricting the pivot bracket 12 again and ensuring that it does not arbitrarily disengage from the engagement position, making the connection between the trolley 1 and the lifting mechanism 4 more stable and reliable.

[0076] In this embodiment, the first reset member 128 provides double protection for the elastic loading of the pivot bracket 12 and the restriction of the locking element 13, which can significantly reduce the possibility of the latch post 125 disengaging from the latch hook 21. In addition, when the pivot bracket 12 reaches the engagement position, the locking element 13 will automatically reset to the locked position and restrict the pivot bracket 12. Therefore, the locking effect of the locking element 13 does not require manual operation, avoiding the situation where the locking is not in place due to forgetting. This ensures that the double protection of the locking element 13 and the first reset member 128 can always be effective, making the locking of the latch post 125 and the latch hook 21 safer and more reliable, which helps to improve the safety of the shifting machine. Secondly, the overall structure of the first reset member 128 and the locking element 13 is relatively simple. During installation and disassembly, the user only needs to press the locking element 13 and then push the pivot bracket 12 to rotate. The whole operation process is relatively simple. In addition, the locking element 13 does not need to be kept pressed during the entire installation and disassembly process, and the user can also complete the entire operation process with one hand, which helps to improve the installation and disassembly efficiency of the lifting mechanism 4.

[0077] Furthermore, during the unlocking process, the movable latch can simultaneously reset the limiting element 14 to the clearance position, thereby releasing the restriction of the limiting element 14 on the locking element 13. This allows the locking element 13 to move to the unlock position while restricting the limiting element 14 to the clearance position. Afterward, when the pivot bracket 12 rotates towards the direction of engagement with the latch hook 21, the limiting element 14 will still remain in the clearance position under the restriction of the locking element 13. Once the latch pin 125 engages with the latch hook 21, the limiting element 14 can smoothly move from the unlock position to the locked position. In other words, the movement of the limiting element 14 does not require manual operation throughout the entire unlocking process, effectively simplifying the operation steps of the detachable coupling device. This makes the installation and disassembly of the lifting mechanism 4 and the trolley 1 simpler and faster, contributing to improved safety and reliability of the lifting mechanism 4. This improves the efficiency of installation and disassembly; it also eliminates the need for components used to operate the limit element 14, simplifying its structure, reducing installation difficulty, and minimizing space usage. Furthermore, the locking element 13 restricts the limit element 14 in the unlocked position, confining it to a clearance position. This prevents the limit element 14 from interfering with the reset of the locking element 13, ensuring automatic reset. Therefore, the reset of the locking element 13 requires no manual operation, preventing incomplete reset due to forgetfulness. This ensures the dual protection of the pivot bracket 12 and the locking element 13 remains effective, making the locking of the latch hook 21 to the pivot bracket 12 safer and more reliable, thus enhancing the safety of the transfer machine.

[0078] It is understandable that in other embodiments, the locking element 13 can also be rotatably connected to the trolley 1, with the first operating member 131 being a knob and the second reset member 132 being a torsion spring. The first operating member 131 drives the locking element 13 to rotate within the interval area, thereby switching between the locked and unlocked positions. In addition, to prevent the locking element 13 from disengaging from the locked position due to the rotation of the pivot bracket 12, the locking element 13 has a long axis and a short axis. The shape of the locking element 13 can be elliptical or cam-shaped. When the locking element 13 is in the locked position, the stop portion 124 abuts against the two ends of the long axis. The force exerted by the rotation of the pivot bracket 12 on the locking element 13 will be directed towards the axis of the locking element 13, so this force will not drive the locking element 13 to rotate. When the pivot bracket 12 is in the locked position, it cannot move the locking element 13 from the locked position to the unlocked position. This ensures that the pivot bracket 12 cannot rotate when the locking element 13 is in the locked position, so that the latch pin 125 and the latch hook 21 can maintain a stable engagement. When the locking element 13 is in the unlocked position, the two ends of the long shaft serve as the upper and lower ends of the locking element 13, and the two ends of the short shaft are between the two stops 124. There is a gap between the two ends of the short shaft and the stops 124, thereby releasing the restriction on the pivot bracket 12. The locking element 13 switches between the locked and unlocked positions by rotation. Both the locked and unlocked positions are within the interval area, that is, the space occupied by the movement path of the locking element 13 is small, so that the locking element 13 can be used in a more compact installation space.

[0079] To reduce the swaying amplitude of the pivot bracket 12 in the locked state, the stop portion 124 in this embodiment is located near the hinge between the pivot bracket 12 and the trolley 1. The locking element 13 and the stop portion 124 are positioned correspondingly. When the locking element 13 is in the locked position, the locking element 13 and the stop portion 124 can form an abutting engagement. The closer the locking element 13 is to the hinge of the pivot bracket 12, the stronger the limiting force of the locking element 13 on the pivot bracket 12. This can reduce the swaying amplitude of the pivot bracket 12 after it is restricted, reduce the noise generated by the swaying of the pivot bracket 12, and help improve the user experience. In addition, the proximity of the stop portion 124 and the locking element 13 to the hinge of the pivot bracket 12 can provide sufficient installation space for the limiting element 14, and can also reduce the overall length of the pivot bracket 12, making the assembly of the detachable coupling device more compact and helping to reduce the volume of the trolley 1.

[0080] like Figure 4As shown, in this embodiment, the trolley 1 includes a housing 11, within which a fixing plate 111 is fixed. The pivot bracket 12, along the unlocking direction of the locking element 13, includes a first locking plate 121 and a second locking plate 122. The first locking plate 121 and the second locking plate 122 are rotatably connected to both sides of the fixing plate 111 via a pivot shaft 123. A latch pin 125 is fixed between the first locking plate 121 and the second locking plate 122 and is located at the lower ends of the first locking plate 121 and the second locking plate 122. A stop portion 124 is located on the side of the first locking plate 121. A rotating member 1221 is fixed to the second locking plate 122. A gap is formed between the two stop portions 124. An operating element 131 is installed on the outer side of the housing 11 near the first locking plate 121. When the first operating element 131 is pressed and the locking element 13 slides, the locking element 13 slides from the interval area toward the position of the second locking plate 122. When the latch hook 21 is locked with the pivot bracket 12, the latch hook 21 is also between the first locking plate 121 and the second locking plate 122. This makes the force on the pivot bracket 12 more balanced, helps to reduce the shear force on the pivot bracket 12, reduces the possibility of deformation or breakage of the pivot bracket 12, helps to extend the service life of the pivot bracket 12, and also improves the safety of the shifting machine.

[0081] It is understandable that in other embodiments, the first locking plate 121 and the second locking plate 122 may also be directly rotatably connected to the inner wall of the housing 11 of the trolley 1 via a rotating shaft 123.

[0082] It should be noted that in this embodiment, the rotating component 1221 and the second locking plate 122 are an integral structure, and the rotating component 1221 and the toothed part 1222 are also an integral structure.

[0083] like Figure 3 As shown, in this embodiment, the movable latch includes a guide pin 126 connected to the pivot bracket 12. The end of the guide pin 126 extends out of the housing 11 of the trolley 1. A trigger element 1261 is installed at the end of the guide pin 126 outside the housing 11. A sensor 1262 is provided on the lifting mechanism 4. The sensor 1262 is electrically connected to an alarm. When the pivot bracket 12 is in the engaged position, the trigger element 1261 is completely within the sensing range of the sensor 1262, and the sensor 1262 deactivates the alarm. When the pivot bracket 12 is in the disengaged position, the trigger element 1261 is completely out of the sensing range of the sensor 1262, and the sensor 1262 deactivates the alarm. When the pivot bracket 12 is between the engaged and disengaged positions, the trigger element 1261 is not completely out of the sensing range of the sensor 1262, and is still partially within the sensing range of the sensor 1262, and the sensor 1262 triggers the alarm.

[0084] After the latching pin 125 and latching hook 21 are stably engaged, the pivot bracket 12 is in the engaged position. At this time, the lifting mechanism 4 and the trolley 1 are stably connected and are unlikely to disengage, so no alarm is needed. When the latching pin 125 and latching hook 21 are unlocked, the pivot bracket 12 is in the disengaged position, and no alarm is needed for unlocking. Since the pivot bracket 12 is elastically loaded by the first reset member 128, it will automatically reset to the engaged position when no force is applied. However, when the latching pin 125 and latching hook 21 are not fully engaged... The latch hook 21 abuts against the latch post 125, thus preventing the pivot bracket 12 from resetting to the engaged position. At this time, the pivot bracket 12 will remain between the engaged and disengaged positions. In this state, the latch post 125 and the latch hook 21 are not reliably engaged. To prevent the user from mistakenly believing that the latch post 125 and the latch hook 21 have been engaged, the sensor 1262 needs to trigger the alarm to remind the user that the latch post 125 and the latch hook 21 are not fully engaged and need to be reinstalled. This ensures that the latch post 125 can maintain a reliable engagement with the latch hook 21, further improving the safety of the lifting system.

[0085] It is understandable that, in other embodiments, the sensor 1262 may also be fixed on the trolley 1.

[0086] like Figure 15 and Figure 16 As shown, in this embodiment, each pivot bracket 12 is provided with two guide pins 126. The two guide pins 126 on the same pivot bracket 12 are respectively located on the extension lines of the two ends of the latch post 125, that is, the guide pins 126 and the latch post 125 are coaxially arranged. This ensures that the movement paths of the latch post 125 and the guide pins 126 are the same, so that the position change of the guide pins 126 can accurately reflect the position change of the latch post 125, which helps to improve the accuracy and reliability of the sensor 1262 in sensing the position of the pivot bracket 12. In addition, each pivot bracket 12 has at least A trigger 1261 is installed on a guide pin 126. The number of sensors 1262 corresponds to the number of triggers 1261. Specifically, in this embodiment, the lifting mechanism 4 is provided with two sensors 1262. The two sensors 1262 are located on both sides of the traveling vehicle, and the two sensors 1262 correspond to two pivot brackets 12. The guide pin 126 of the pivot bracket 12 corresponding to the sensor 1262 is equipped with a trigger 1261. That is, each pivot bracket 12 is equipped with a trigger 1261, and the trigger 1261 is also located on both sides of the trolley 1.

[0087] It is understandable that in other embodiments, the number of triggers 1261 and sensors 1262 may be three or four.

[0088] like Figure 15and Figure 16 As shown, in this embodiment, the pivot brackets 12 move closer to each other, causing the latch pin 125 to disengage from the latch hook 21. When the pivot bracket 12 rotates from the engaged position to the disengaged position, the trigger 1261 rises. That is, in the height direction, the trigger 1261 at the engaged position is lower than the trigger 1261 at the disengaged position. The sensor 1262 tilts downwards in the unlocking direction of the pivot bracket 12, meaning the highest point of the sensor 1262 corresponds to the trigger 1261 at the engaged position, and the lowest point of the sensor 1262 corresponds to the trigger 1261 at the disengaged position. When the pivot bracket 12 is in the engaged position, the highest point of the sensor 1262 is directly in front of the trigger 1261, so that the trigger 1261 is completely within the sensing range of the sensor 1262. (Refer to...) Figure 15 As shown; when the pivot bracket 12 is in the disengaged position, the lowest point of the sensor 1262 is lower than the trigger 1261, so that the trigger 1261 is completely out of the sensing range of the sensor 1262, reference. Figure 16 As shown; when the pivot bracket 12 is between the engaged and disengaged positions, the trigger 1261 is only partially within the sensing range of the sensor 1262. At this time, the sensor 1262 will trigger the alarm to alert the user that the latch post 125 and the latch hook 21 are not fully engaged.

[0089] like Figure 3 As shown, in this embodiment, the trigger 1261 is a magnet, and the sensor 1262 is a reed switch. The reed switch has two contacts, and the spring inside the reed switch swings between the two contacts under the action of the magnetic field. When the spring contacts one of the contacts, the alarm is deactivated. When the pivot bracket 12 is in the initial engaged position, the sensor 1262 is directly in front of the trigger 1261, and the spring is subjected to the greatest magnetic force. At this time, the spring contacts the contact closest to the trigger 1261 under the action of the magnetic force. When the pivot bracket 12 is in the disengaged position, the sensor 1262 and the trigger 1261 are misaligned. At this time, the spring is subjected to the least magnetic force, and the spring contacts the contact of the trigger 1261 under the action of its own elasticity. When the pivot bracket 12 is between the engaged and disengaged positions, the spring is held between the two contacts under the action of the magnetic force and its own elasticity. At this time, the spring does not contact the contacts, and the alarm sounds.

[0090] The guide pin 126 and the latch post 125 are coaxially arranged. In addition, the lifting mechanism 4 is provided with a pair of release sliders 22. The two release sliders 22 can be operably slid towards each other to push the pivot bracket 12 to rotate. When the lifting mechanism 4 is connected to the trolley 1, the guide pin 126 is in the sliding path of the release slider 22. When the user pushes the release slider 22, the release slider 22 drives the pivot bracket 12 to rotate to the disengaged position through the guide pin 126, thereby unlocking the latch post 125 and the latch hook 21. After unlocking, the lifting mechanism 4 will automatically separate from the trolley 1 under the action of gravity and the release slider 22 will be set on the lifting mechanism 4. During the unlocking process, the user needs to hold the lifting mechanism 4 when pushing the release slider 22. Therefore, after the lifting mechanism 4 is separated from the trolley 1, the user can still hold the lifting mechanism 4 to avoid the lifting mechanism 4 falling and being damaged. At the same time, there is no need for additional protection of the lifting mechanism 4, which makes it convenient for the user to disassemble with one hand.

[0091] like Figure 3 and Figure 14 As shown, in this embodiment, the lifting mechanism 4 is provided with a pair of blocking blocks 413. The blocking blocks 413 abut against the release slider 22 to limit the minimum distance between the two release sliders 22. In addition, the release slider 22 is at least partially supported on the top wall 411 of the lifting mechanism 4 during the sliding process. Through the support of the lifting mechanism 4 on the release slider 22, the friction between the release slider 22 and the slide groove can be reduced, making the sliding of the release slider 22 smoother and reducing the possibility of the release slider 22 getting stuck.

[0092] It should be noted that in this embodiment, both the first locking plate 121 and the second locking plate 122 are provided with guide pins 126 extending out of the trolley 1 housing 11, that is, guide pins 126 are exposed on both sides of the trolley 1. The lifting mechanism 4 is slidably mounted with two release sliders 22, which are used to push the two pivot brackets 12 respectively. When the two guide pins 126 approach each other, they drive the two pivot brackets 12 to rotate towards each other, so that the pivot brackets 12 can rotate to the unlocked position. The release sliders 22 are provided with two guide surfaces 221 for pushing the guide pins 126. Two guide pins 126 are used to push the same pivot bracket 12. A clearance groove 222 is provided between the two guide surfaces 221. During the sliding of the release slider 22, the side of the trolley 1 will enter the clearance groove 222 to avoid mutual interference between the release slider 22 and the trolley 1. In addition, the guide surface 221 is a curved surface, which gradually bends away from the guide pin 126 from bottom to top. That is, the distance between the two opposing guide surfaces 221 gradually increases from bottom to top. The distance between the tops of the two opposing guide surfaces 221 is D. The two guide pins 126 are opposite to each other. The distance between the outer sides of the two release sliders 22 is d. No matter where the two release sliders 22 slide, the distance between the tops of the two opposing guide surfaces 221 is always greater than the distance between the opposite outer sides of the two guide pins 126, i.e., D > d. When the release slider 22 abuts against the blocking block 413, the distance between the two release sliders 22 is minimum. When the pivot bracket 12 is in the engaged position, the distance between the guide pins 126 of the two pivot brackets 12 is maximum. In this state, the distance between the tops of the two guide surfaces 221 is still greater than the distance between the two guide pins 126, ensuring that the trolley 1 and the lifting... During the engagement of the lowering mechanism 4, the guide pin 126 can be positioned between the two release sliders 22. As the trolley 1 is gradually inserted into the slot 412, the guide pin 126 can push the two release sliders 22 away from each other, allowing the release sliders 22 to return to the end of the slide groove. This allows the user to push the guide pin 126 again through the release sliders 22. During the connection process between the trolley 1 and the lifting mechanism 4, the user does not need to manually reset the two release sliders 22, which can further reduce the connection difficulty between the trolley 1 and the lifting mechanism 4 and help improve the installation efficiency of the trolley 1 and the lifting mechanism 4.

[0093] like Figures 10 to 13 As shown, regarding the disassembly process of the trolley 1 and the lifting mechanism 4, before disassembly, the lifting mechanism 4 is fixedly connected to the trolley 1 via a detachable coupling device. At this time, the latch pin 125 is in the engaged position and remains engaged with the latch hook 21, while the locking element 13 is in the locked position, simultaneously restricting the pivot bracket 12 and the limiting element 14. (Refer to...) Figure 10As shown; during disassembly, the user first pushes the locking element 13 to the unlocked position by pressing the first operating member 131. At this time, the locking element 13 releases the restriction on the pivot bracket 12 and the limiting element 14. The pivot bracket 12 can rotate freely between the engaged and disengaged positions, while the limiting element 14 will automatically rotate to the blocking position under the action of the third reset member 143. At the same time, the first protrusion 141 and the second protrusion 142 will both rotate upward with the limiting element 14. The first protrusion 141 will enter the sliding path of the locking element 13, and the second protrusion 142 will enter the rotation path of the pivot bracket 12. The first protrusion 141 will block the locking element 13 from moving to the locked position, thus restricting the locking element 13 to the unlocked position. At this time, even if the user releases the first operating member 131, the locking element 13 will not reset to the locked position. Then, the user drags the pivot bracket 12 to rotate by releasing the slider 22, so that the latch pin 125 disengages from the latch hook 21, thereby unlocking the trolley 1 and the lifting mechanism 4, and thus disassembling the lifting mechanism 4. (Refer to...) Figure 11 As shown; during the rotation of the pivot bracket 12, the pivot bracket 12 pushes the limiting element 14 back to the avoidance position through the second protrusion 142. At this time, the first protrusion 141 releases the restriction on the locking element 13, and the locking element 13 moves to the locking position under the action of the first reset member 128. However, since the pivot bracket 12 has already rotated to the unlocked position, that is, the stop part 124 of the pivot bracket 12 occupies the space of the locking element 13 in the locking position, the locking element 13 will abut against the surface of the stop part 124 facing away from the pressing member. The locking element 13 still cannot be reset to the initial position. At this time, the locking element 13 stays in the first position under the obstruction of the stop part 124. At this time, the locking element 13 will abut against the first protrusion 141, thereby restricting the rotation of the limiting element 14. (Refer to...) Figure 12 and Figure 13 As shown; after the lifting mechanism 4 is completely removed, the pivot bracket 12 loses the thrust of the release slider 22 and automatically resets to the engagement position under the action of the first reset member 128, so that a complete locking position can be provided again in the interval area. After the pivot bracket 12 rotates to the engagement position, the stop part 124 separates from the locking element 13. The locking element 13 automatically resets to the locking position under the action of the second reset member 132. The two stop parts 124 are abutted by the locking element 13 to restrict the rotation of the pivot bracket 12, ensuring that the pivot bracket 12 will not arbitrarily disengage from the engagement position.

[0094] Regarding the installation process of the trolley 1 and the lifting mechanism 4, during use, the user first presses the first operating component 131 to move the locking element 13 to the unlocked position, thereby releasing the restriction on the pivot bracket 12 and the limiting element 14. Then, the entire lifting mechanism 4 is pushed upward, causing the latch hook 21 to extend into the trolley 1. The top of the latch hook 21 has a guide surface, and the latch hook 21 will push the pivot bracket 12 to rotate to the disengaged position. When the pivot bracket 12 rotates to the disengaged position, the latch hook 21 is installed in place, and then the pivot bracket 12 will be in the first Under the action of the reset member 128, it automatically resets to the locked position, thereby locking the latch hook 21 and the latch post 125. During the installation process, the movement process of the locking element 13 and the limiting element 14 is the same as that of the disassembly process. In addition, in order to ensure that the release slider 22 can automatically reset, the top of the action part of the release slider 22 in this embodiment is also provided with a guide surface. During the process of the latch hook 21 extending into the trolley 1, the guide pin 126 pushes the two release sliders 22 to automatically separate through the guide surface, so as to avoid the release slider 22 interfering with the installation of the lifting mechanism 4 and the trolley 1.

[0095] Example 2:

[0096] like Figure 17 As shown, the main difference between this embodiment and Embodiment 1 is that the transmission component in this embodiment is a transmission belt 1223 that is interference-fitted with the rotating component 1221. The transmission belt 1223 is wrapped around the two rotating components 1221 in a figure-eight pattern. When one rotating component 1221 rotates, it drives the other rotating component 1221 to rotate in the opposite direction through the transmission belt 1223. By driving the two rotating components 1221 to rotate simultaneously through the transmission belt 1223, the difficulty of installing and disassembling the transmission belt 1223 and the rotating component 1221 can be effectively reduced, which helps to reduce the maintenance difficulty of the transmission mechanism and improve the installation and replacement efficiency of the transmission belt 1223.

[0097] Example 3:

[0098] like Figure 18 As shown, the main difference between this embodiment and Embodiment 1 is that the transmission component in this embodiment is a linkage assembly. The linkage assembly includes two fixed rods 1224 radially distributed along the rotating component 1221 and a movable rod 1225 hinged at both ends to the two fixed rods 1224 respectively. The two fixed rods 1224 are fixed to the two rotating components 1221 respectively. One fixed rod 1224 is located on the upper side of the rotating component 1221, and the other fixed rod 1224 is located on the lower side of the rotating component 1221. The rotation of one rotating component 1221 drives the fixed rod 1224 to rotate. The fixed rod 1224 drives the other fixed rod 1224 to rotate through the movable rod 1225, and the other rotating component 1221 rotates accordingly, thereby realizing the synchronous and opposite rotation of the two rotating components 1221.

[0099] Example 4:

[0100] The main difference between this embodiment and Embodiment 1 is that in this embodiment, the rotation of one pivot bracket 12 drives the other pivot bracket 12 to rotate synchronously and in the same direction through a transmission mechanism. The two rotating parts 1221 in the transmission mechanism are gears, and the transmission part is also a gear. That is, the transmission part meshes with the two rotating parts 1221 at the same time. When one rotating part 1221 rotates, it will drive the other rotating part 1221 to rotate synchronously and in the same direction through the transmission part.

[0101] It is understandable that in other embodiments, the transmission component can also be a transmission belt 1223 that is interference-fitted with the rotating component 1221. The transmission belt 1223 is fitted on the outer periphery of the two rotating components, that is, the two rotating components 1221 are simultaneously located on the inner side of the transmission belt 1223. One of the rotating components 1221 rotates and drives the other rotating component 1221 to rotate in the same direction through the transmission belt 1223.

[0102] It is understandable that in other embodiments, the transmission component is a linkage assembly. The linkage assembly includes two fixed rods 1224 radially distributed along the rotating component 1221 and a movable rod 1225 hinged at both ends to the two fixed rods 1224 respectively. The two fixed rods 1224 are fixed to the two rotating components 1221 respectively, and the two fixed rods 1224 are in the same position on the two rotating components 1221. When one rotating component 1221 rotates, it drives the fixed rod 1224 to rotate. The fixed rod 1224 drives the other fixed rod 1224 to rotate through the movable rod 1225, and the other rotating component 1221 rotates accordingly, thereby realizing the synchronous and directional rotation of the two rotating components 1221.

Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
