Abstract
Description
Technical Field
[0001] This invention relates to the field of mechanical lock technology, and in particular to a double-sided locking mechanism that is compatible with positional deviations. Background Technology
[0002] A carriage is a lifting device used to support cargo and allow it to run along an overhead track, or to support the weight of a chain to prevent excessive deflection of the chain.
[0003] In related technologies, the carriage moves axially along the guide rail. To ensure that the two carriages are locked after they have reached their positions, two power sources are typically used to drive locking mechanisms to lock the two carriages. During the locking action, a rigid pin is usually engaged with a pin hole on the carriage for locking.
[0004] However, when using a rigid pin and pin hole for locking, the center axis of the pin and the pin hole must be aligned during operation for the pin to be inserted into the pin hole. This requires high precision in the carriage's stopping position. If there is a certain deviation between the actual stopping position and the predetermined stopping position of the carriage, the pin may not be able to be inserted into the pin hole, resulting in the failure of the carriage position locking. Therefore, it is necessary to propose a double-sided locking mechanism that can accommodate position deviations to solve the above problems. Summary of the Invention
[0005] This invention provides a double-sided locking mechanism that is compatible with positional deviations, in order to solve the problem in related technologies where the use of rigid pins and pin holes for locking requires high accuracy in the carriage stop position.
[0006] This invention provides a double-sided locking mechanism compatible with positional deviations, comprising:
[0007] A slider, wherein the slider has a sliding degree of freedom along the Y direction, and at least two locking grooves are provided on the slider along the Y direction;
[0008] The mounting bracket is located on the opening side of the lock groove. A locking rod that slidably connects to the mounting bracket and cooperates with the lock groove is provided. The cross-sections of the lock groove and the locking rod gradually decrease along the extension direction of the locking rod. The axial distance between two adjacent locking rods is greater than or less than the center distance between two adjacent lock grooves.
[0009] In some embodiments, the inner wall of the locking groove is a tapered surface, and the end of the locking rod is provided with a chamfer adapted to the tapered surface. The chamfer and the tapered surface abut against each other to limit the sliding member in the Y direction.
[0010] In some embodiments, a drive mechanism and a linkage mechanism are also included on the mounting bracket, wherein the drive mechanism drives the locking rod to enter or disengage from the locking groove through the linkage mechanism.
[0011] In some embodiments, the linkage mechanism includes a connecting rod and a swing rod. The two ends of the connecting rod are provided with elongated holes extending along the length of the connecting rod and used for rotatably connecting the locking rod. The driving mechanism drives the swing rod to move the connecting rod so that the connecting rod pushes the locking rod to move.
[0012] In some embodiments, the linkage mechanism further includes a crossbar located between two adjacent locking rods and slidably connected to the mounting bracket, the crossbar and the connecting rod being rotatably connected, and the swing arm being rotatably connected to the connecting rod or the crossbar.
[0013] In some embodiments, the driving mechanism includes a locking mechanism and an unlocking mechanism. The locking mechanism drives the locking rod into the lock slot through a linkage mechanism, and the unlocking mechanism drives the locking rod out of the lock slot through a linkage mechanism.
[0014] In some embodiments, the locking mechanism includes a guide rod disposed on a mounting bracket and a guide sleeve slidably connected to the guide rod and rotatably connected to the rocker arm. The guide rod is provided with a first elastic element that compresses the guide sleeve. The first elastic element uses elastic force to drive the guide sleeve to move along the guide rod so that the guide rod drives the rocker arm to push the connecting rod to move.
[0015] In some embodiments, the unlocking mechanism includes a motor mounted on a mounting bracket, the output end of which is connected to a lead screw via a coupling, a sliding sleeve is threaded onto the lead screw, and a push plate for pushing the guide sleeve to press against the first elastic element is fixed on the sliding sleeve.
[0016] In some embodiments, the mounting bracket is provided with a mounting shell with an opening facing the extension direction of the locking rod, the locking rod is slidably connected to the mounting shell, the opening of the mounting shell is provided with a mounting cover for guiding the locking rod, and the side wall of the locking rod is provided with a flange to prevent the locking rod from detaching from the mounting shell;
[0017] The locking rod is a stepped shaft, with the stepped surface of the stepped shaft facing away from the mounting cover, and a second elastic element is provided on the stepped shaft to abut against the stepped surface and the mounting shell.
[0018] In some embodiments, the mounting bracket is provided with a limiting sleeve for the crossbar to pass through, an annular block is fixed at the end of the crossbar away from the connecting rod, the mounting bracket is provided with a clearance hole to avoid the annular block, and a third elastic element is provided on the crossbar between the annular block and the limiting sleeve.
[0019] The beneficial effects of the technical solution provided by this invention include:
[0020] This invention provides a double-sided locking mechanism that is compatible with positional deviations. The sliding member has a sliding degree of freedom along the Y direction, and at least two locking grooves are provided on the sliding member along the Y direction. The mounting bracket is located on the opening side of the locking groove, and a locking rod that cooperates with the locking groove is slidably connected on the mounting bracket. The cross-sections of the locking groove and the locking rod gradually decrease along the extension direction of the locking rod, and the axial distance between two adjacent locking rods is greater than or less than the center distance between two adjacent locking grooves.
[0021] Therefore, the locking mechanism of the present invention has position deviation compatibility. When the actual stopping position of the sliding member with the pin hole deviates from the predetermined position, since the cross-section of the locking groove and the locking rod gradually decreases along the extension direction of the locking rod, and the central axis of the locking rod and the locking groove deviates, the locking rod can at least partially enter the locking groove. At the same time, since the axial distance between two adjacent locking rods is greater than or less than the center distance between two adjacent locking grooves, the two adjacent locking rods can abut against the opposite or back sides of the two locking grooves, thereby restricting the movement of the sliding member in the Y direction. Thus, it can be compatible with the position deviation of the sliding member when it stops within a certain range, reducing the accuracy requirements of the stopping position of the sliding member.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] This invention provides a double-sided locking mechanism that is compatible with positional deviations, which can solve the problem of high accuracy requirements for the stop position of the carriage when using rigid pins and pin holes for locking in related technologies.
[0034] See Figures 1 to 5 As shown, this embodiment of the invention provides a double-sided locking mechanism compatible with positional deviations, comprising:
[0035] The slider has a sliding degree of freedom along the Y direction, and at least two locking grooves are provided on the slider along the Y direction.
[0036] Mounting bracket 1 is located on the opening side of the lock groove. A locking rod that mates with the lock groove is slidably connected to the mounting bracket 1. The cross-sections of the lock groove and the locking rod gradually decrease along the extension direction of the locking rod. The axial distance between two adjacent locking rods is greater than or less than the center distance between two adjacent lock grooves.
[0037] The locking mechanism of this invention has position deviation compatibility. Since the cross-sections of the lock groove and the lock rod gradually decrease along the extension direction of the lock rod, when there is a deviation between the central axes of the lock rod and the lock groove, the lock rod can at least partially enter the lock groove and abut against the lock groove when the lock rod is driven to move.
[0038] Since the axial distance between two adjacent locking rods is greater than or less than the center distance between two adjacent locking slots, the two adjacent locking rods can abut against the opposite or back sides of the two locking slots, thereby restricting the movement of the slider in the Y direction. This allows for compatibility with the positional deviation of the slider when it stops within a certain range, reducing the accuracy requirements for the slider's stopping position.
[0039] Specifically, in this embodiment, the sliding component is a slide 23, which can be arranged on both sides of the mounting bracket 1. The locking rods include an upper left locking rod 13, a lower left locking rod 14, an upper right locking rod 21, and a lower right locking rod 22. The upper left locking rod 13 and the lower left locking rod 14 cooperate with the slide 23 on the left side, and the upper right locking rod 21 and the lower right locking rod 22 cooperate with the slide 23 on the right side.
[0040] The axial distance between the two locking rods on the right is slightly greater than the center distance between the two locking grooves on the right carriage 23. The dotted line at point A in the diagram represents the predetermined stop position. When the centerline perpendicular to the Y direction on carriage 23 coincides with the dotted line, it indicates that carriage 23 is at the predetermined stop position. In the diagram, A' represents the centerline perpendicular to the Y direction on carriage 23. If A' deviates from A, it means that the actual stop position of carriage 23 deviates from the predetermined stop position.
[0041] In the above situation, the upper right locking rod 21 and the lower right locking rod 22 can move to the right by different distances and then contact and press against their respective locking grooves, thereby restricting the movement of the right side carriage 23 and achieving the effect of the locking mechanism being compatible with the positional deviation of the carriage 23.
[0042] Specifically, the upper right locking rod 21 enters and abuts against the upper side wall of the locking groove, and the lower right locking rod 22 enters and abuts against the lower side wall of the locking groove. The upper right locking rod 21 and the lower right locking rod 22 cooperate with each other to limit the slide 23 on the right side in the Y direction.
[0043] Similarly, when the axial distance between the two locking rods on the right is slightly less than the center distance between the two locking slots on the right slide 23, the upper right locking rod 21 can enter and abut against the lower side wall of the locking slot, and the lower right locking rod 22 can enter and abut against the upper side wall of the locking slot. The upper right locking rod 21 and the lower right locking rod 22 cooperate to limit the right slide 23 in the Y direction. Similarly, the left slide 23 is limited in the same way. The cooperation between the upper left locking rod 13 and the lower left locking rod 14 and the left slide 23 is not described in detail.
[0044] It should be noted that the present invention excludes the case where the axial distance between two adjacent locking rods is equal to the center distance between the two locking slots on the slide 23. In this case, when the actual stop position A' of the slide 23 deviates upward from the predetermined stop position A as shown in the figure, the upper right locking rod 21 and the lower right locking rod 22 will respectively abut against the lower side of the corresponding locking slot. It can only limit the direction of the arrow pointing upward on the Y-axis in the figure, and cannot limit the direction of the arrow pointing downward on the Y-axis in the figure.
[0045] In some alternative embodiments: see Figures 1 to 5 As shown, this embodiment of the invention provides a double-sided locking mechanism that is compatible with positional deviations. The inner wall of the locking groove of the double-sided locking mechanism is a tapered surface, and the end of the locking rod is provided with a chamfer that matches the tapered surface. The chamfer and the tapered surface abut against each other to limit the sliding member in the Y direction.
[0046] In this embodiment of the invention, the inner wall of the lock groove is a conical surface, and the end of the lock rod is provided with a chamfer. The chamfer and the conical surface are compatible. When there is a certain deviation between the central axis of the lock rod and the lock groove, the lock rod that is slidably connected to the mounting bracket 1 can also partially slide into the lock groove and abut against the conical surface of the lock groove. The two adjacent lock rods cooperate with each other to limit the sliding member in the Y direction.
[0047] It should be noted that in some other alternative embodiments, the ends of the lock groove and the lock rod can be one of the following shapes: triangular, trapezoidal, or spherical.
[0048] In some alternative embodiments: see Figures 1 to 5 As shown, this embodiment of the invention provides a double-sided locking mechanism that is compatible with positional deviations. The double-sided locking mechanism that is compatible with positional deviations also includes a drive mechanism and a linkage mechanism disposed on the mounting frame 1. The drive mechanism drives the locking rod to enter or disengage from the locking groove through the linkage mechanism.
[0049] The linkage mechanism includes a connecting rod and a rocker arm. Both ends of the connecting rod are provided with elongated holes that extend along the length of the connecting rod and are used to rotatably connect to the locking rod. The drive mechanism drives the rocker arm to move the connecting rod so that the connecting rod pushes the locking rod to move.
[0050] The linkage mechanism of this invention includes a connecting rod and a swing rod. The connecting rod has elongated holes at both ends. The locking rod is rotatably connected to the elongated holes via a short shaft. Specifically, the swing rod is rotatably connected at the middle position of the connecting rod. When the driving mechanism drives the swing rod to swing, the swing rod pushes the connecting rod to move, and the connecting rod pushes the two locking rods on it to slide out along the mounting bracket 1.
[0051] Because there is a deviation between the center lines of the slide groove and the locking rod when the slider stops, when one locking rod on the connecting rod abuts against the wall of the locking groove, the connecting rod can swing and slide relative to the locking rod. Under the push of the swing rod, the connecting rod drives another locking rod on it to continue to slide out and abut against another part of the locking groove wall, thereby limiting the slider in the Y direction.
[0052] That is, the connecting rod that connects the two locking rods can swing, so the locking rod at one end of the connecting rod can move a certain distance further in the corresponding locking groove than the locking rod at the other end, ensuring that the locking rods are both in contact with the corresponding locking grooves and locked, thereby restricting the movement of the sliding parts and achieving the effect of the locking mechanism being compatible with the position deviation of the sliding parts.
[0053] In some alternative embodiments: see Figures 1 to 5 As shown, this embodiment of the invention provides a double-sided locking mechanism that is compatible with positional deviations. The linkage mechanism of the double-sided locking mechanism that is compatible with positional deviations further includes a crossbar located between two adjacent locking rods and slidably connected to the mounting frame 1. The crossbar and the connecting rod are rotatably connected, and the swing rod is rotatably connected to the connecting rod or the crossbar.
[0054] In this embodiment of the invention, a through hole is provided at the middle position of the connecting rod. The crossbar is slidably connected to the mounting bracket 1 and passes through the through hole before being hinged to the connecting rod. The swing arm can be rotatably connected to the crossbar or the connecting rod. When the swing arm pushes the connecting rod to move, the crossbar can play a guiding role.
[0055] Specifically, in this embodiment, the swing arm includes a left swing arm 10 and a right swing arm 18, the crossbar includes a left crossbar 11 and a right crossbar 19, the connecting rod includes a left connecting rod 12 and a right connecting rod 20, the drive mechanism connects the left swing arm 10 and the right swing arm 18, the end of the left swing arm 10 away from the drive mechanism is rotatably connected to the left crossbar 11, the left crossbar 11 is rotatably connected to the left connecting rod 12, and the long oval holes at both ends of the left connecting rod 12 are rotatably connected to the upper left locking rod 13 and the lower left locking rod 14 respectively through short shafts.
[0056] The end of the right swing arm 18 away from the drive mechanism is rotatably connected to the right crossbar 19. The right crossbar 19 is rotatably connected to the right connecting rod 20. The long oval holes at both ends of the right connecting rod 20 are rotatably connected to the upper right locking rod 21 and the lower right locking rod 22 respectively through short shafts, so that the locking rods on both the left and right sides can be driven to position the corresponding carriage 23.
[0057] In some alternative embodiments: see Figures 1 to 5 As shown, this embodiment of the invention provides a double-sided locking mechanism that is compatible with positional deviations. The driving mechanism of this double-sided locking mechanism that is compatible with positional deviations includes a locking mechanism and an unlocking mechanism. The locking mechanism drives the locking rod into the locking groove through a linkage mechanism, and the unlocking mechanism drives the locking rod out of the locking groove through a linkage mechanism.
[0058] The locking mechanism includes a guide rod mounted on the mounting bracket 1, and a guide sleeve slidably connected to the guide rod and rotatably connected to the rocker arm. A first elastic element is provided on the guide rod to compress the guide sleeve. The first elastic element uses elastic force to drive the guide sleeve to move along the guide rod so that the guide rod drives the rocker arm to push the connecting rod to move.
[0059] The locking mechanism of this invention utilizes a first elastic element to push a guide sleeve to slide along a guide rod. The guide sleeve then drives a rocker arm to swing, thereby pushing a connecting rod to move. The connecting rod then pushes a locking rod to slide into the locking groove.
[0060] Specifically, in this embodiment, the guide rods include a left guide rod 8 and a right guide rod 16, both of which are fixed to the mounting bracket 1 by bolts. The guide sleeves include a left guide sleeve 7 and a right guide sleeve 15. The first elastic element includes a left main spring 9 and a right main spring 17. The left guide sleeve 7 is rotatably connected to the left swing rod 10, and the right guide sleeve 15 is rotatably connected to the right swing rod 18.
[0061] When the locking rod is not slid out of the mounting bracket 1, both the left main spring 9 and the right main spring 17 are in a compressed state. When the locking rod needs to slide out of the locking sliding member, the elastic force of the left main spring 9 and the right main spring 17 drives the left guide sleeve 7 and the right guide sleeve 15 to move respectively. The left guide sleeve 7 and the right guide sleeve 15 drive the left swing rod 10 and the right swing rod 18 to swing respectively. The left swing rod 10 and the right swing rod 18 then drive the locking rod that is indirectly connected to them to move respectively.
[0062] Because the left main spring 9 and the right main spring 17 are independent of each other, the locking actions on both sides are independent. The transmission chains on both sides are independent, so if one side cannot lock properly due to jamming or other factors, the locking operation on the other side is unaffected.
[0063] Simultaneously, when the locking rod engages in locking operation, the force comes solely from the spring, providing instantaneous action. If external factors such as vibration cause a gap between the locking rod and the locking groove, the spring force immediately ensures that the locking rod and locking groove make contact and lock tightly.
[0064] In some alternative embodiments: see Figures 1 to 5 As shown, this embodiment of the invention provides a double-sided locking mechanism that is compatible with positional deviations. The unlocking mechanism of the double-sided locking mechanism that is compatible with positional deviations includes a motor 2 mounted on a mounting frame 1. The output end of the motor 2 is connected to a lead screw 4 via a coupling 3. A sliding sleeve 5 is threaded onto the lead screw 4. A push plate 6 for pushing the guide sleeve to squeeze the first elastic element is fixed on the sliding sleeve 5.
[0065] In this embodiment of the invention, the unlocking mechanism uses a motor 2 to drive a lead screw 4 to rotate, which in turn drives a push plate 6 to push a guide sleeve to squeeze the first elastic element through a sliding sleeve 5 threaded on the lead screw 4. The guide sleeve drives a swing rod to pull the lock rod, which is indirectly connected to it, to reset.
[0066] Specifically, the push plate 6 is bolted to the sliding sleeve 5. The push plate 6 is provided with sliding holes that cooperate with the left guide rod 8 and the right guide rod 16 respectively. The left guide rod 8 and the right guide rod 16 pass through the sliding holes on the push plate 6, thereby restricting the sliding sleeve 5 from rotating with the lead screw 4. The left guide sleeve 7 and the right guide sleeve 15 abut against the top surface of the push plate 6 under the action of elastic force.
[0067] When the locking mechanism needs to be unlocked, the motor 2 drives the lead screw 4 to rotate. The sliding sleeve 5 connected to the thread on the lead screw 4 drives the push plate 6 to push the left guide sleeve 7 and the right guide sleeve 15 to squeeze the left main spring 9 and the right main spring 17 respectively. The left swing rod 10 on the left guide sleeve 7 and the right swing rod 18 on the right guide sleeve 15 swing accordingly. The left swing rod 10 and the right swing rod 18 pull the left crossbar 11 and the right crossbar 19 respectively, so that the left connecting rod 12 and the right connecting rod 20 move closer to each other. The left upper locking rod 13 and the left lower locking rod 14 on the left connecting rod 12, and the right upper locking rod 21 and the right lower locking rod 22 on the right connecting rod 20 move and disengage from the lock groove.
[0068] In some alternative embodiments: see Figures 1 to 5 As shown, this embodiment of the invention provides a double-sided locking mechanism that is compatible with positional deviations. The mounting frame 1 of the double-sided locking mechanism that is compatible with positional deviations is provided with a mounting shell with an opening facing the extension direction of the locking rod. The locking rod is slidably connected in the mounting shell. The opening of the mounting shell is provided with a mounting cover for guiding the locking rod. The side wall of the locking rod is provided with a flange to prevent the locking rod from detaching from the mounting shell.
[0069] The locking rod is a stepped shaft, with the stepped surface of the stepped shaft facing away from the mounting cover. A second elastic element is provided on the stepped shaft that abuts against the stepped surface and the mounting shell.
[0070] The mounting shell of this invention is used to install the locking rod, which can increase the overall strength. Specifically, the mounting shell is fixed to the mounting frame 1 by welding, and the mounting cover is fixed to the opening of the mounting shell by bolt connection, which facilitates the disassembly and installation of the locking rod. The second elastic element is a spring. When the locking rod does not slide out of the mounting frame 1, the spring on the locking rod is in a compressed state.
[0071] When the rocker arm pushes the crossbar to drive the connecting rod to move the locking rod out, the locking rod can slide out quickly with the help of the spring force on the locking rod, avoiding the locking rod from getting stuck during the locking transmission process. At the same time, the flange on the locking rod can prevent the locking rod from sliding out of the mounting shell under the action of the spring force during installation.
[0072] In some alternative embodiments: see Figures 1 to 5 As shown, this embodiment of the invention provides a double-sided locking mechanism that is compatible with positional deviations. The mounting frame 1 of the double-sided locking mechanism is provided with a limiting sleeve for the crossbar to pass through. An annular block is fixed at the end of the crossbar away from the connecting rod. The mounting frame 1 is provided with a clearance hole to avoid the annular block. A third elastic member is provided on the crossbar between the annular block and the limiting sleeve.
[0073] In this embodiment of the invention, a limiting sleeve is welded onto the mounting bracket 1. A crossbar is slidably connected inside the limiting sleeve. An annular block is threaded to the end of the crossbar away from the connecting rod. A third elastic element between the annular block and the limiting sleeve is a spring. When the locking rod is not slid out of the mounting bracket 1, the spring on the crossbar is in a compressed state. When the swing arm pushes the crossbar to move, with the assistance of the elastic force of the spring on the crossbar, the crossbar can quickly drive the connecting rod to drive the locking rod to slide out, avoiding jamming of the locking rod during the locking transmission process.
