Description

Technical Field

[0001] This utility model relates to the field of equipment transportation technology, and in particular to a locking mechanism. Background Technology

[0002] Currently, various small and micro devices or modules are widely used due to their compact design and multifunctional integration. These devices or modules usually contain movable parts. If the movable parts are not effectively fixed, they can easily shift during transportation due to external environmental vibrations or collisions, which can affect the performance and lifespan of the device or module.

[0003] Currently, the main method for fixing movable parts in small devices or modules is to fix them inside the device or module. However, due to internal space limitations, there is often not enough space to install additional fixing devices, which may result in insecure fixing. Furthermore, fixing or unfixing may require disassembling the device casing or other components, which is a complex operation and may also pose a potential risk of damage to the device. Utility Model Content

[0004] The main purpose of this invention is to provide a locking mechanism that facilitates the effective fixation of internal movable parts from the outside of the device.

[0005] To achieve the above objectives, the present invention proposes a locking mechanism for locking or releasing components to be fixed inside a housing. The locking mechanism includes:

[0006] A mounting base for connecting the housing;

[0007] An adjusting column passes through the fixed base and is slidably connected to the fixed base; the locking end of the adjusting column extends into the interior of the housing.

[0008] An adjustment structure is driven to connect with the adjustment column, making the length of the locking end of the adjustment column extending out of the fixing seat adjustable, so that the locking end of the adjustment column is in a locked position or an unlocked position; in the locked position, the adjustment column is connected to the component to be fixed, and in the unlocked position, the adjustment column is separated from the component to be fixed.

[0009] In one embodiment, the adjustment structure includes:

[0010] An elastic element is disposed within the fixed base. The elastic element is in a compressed state and has a restoring force so that the adjusting column tends to move away from the component to be fixed.

[0011] Two locking positions are provided, each located on the fixed base, and the two locking positions have different heights. One of the two locking positions forms the locking position, and the other of the two locking positions forms the unlocking position.

[0012] A crossbar is provided on the adjusting column;

[0013] The adjusting column moves toward the component to be fixed against the elastic force of the elastic element and can rotate so that the crossbar is engaged in one of the two locking positions under the elastic force of the elastic element.

[0014] In one embodiment, the adjustment structure further includes a fixing plate, which is disposed at the end of the adjustment column away from the component to be fixed. The elastic element is sleeved on the outer periphery of the adjustment column, with one end connected to the fixing seat and the other end abutting against the side of the fixing plate facing the fixing seat.

[0015] In one embodiment, the fixing plate is connected to the adjusting column by screws.

[0016] In one embodiment, the two slots are respectively configured as a first slot and a second slot, the first slot and the second slot are spaced apart, and the first slot and the second slot extend from the end of the fixing base near the part to be fixed to the end away from the part to be fixed.

[0017] The height of the first card slot is greater than the height of the second card slot.

[0018] In one embodiment, the adjusting column is provided with a through hole in the radial direction, the crossbar is disposed in the through hole, and both ends of the crossbar protrude from the through hole and engage with the first slot / second slot.

[0019] In one embodiment, the locking mechanism further includes a limiting structure, which is disposed on the fixed base and cooperates with the housing to restrict the rotation of the fixed base.

[0020] In one embodiment, the limiting structure is configured as a limiting post that extends in a direction away from the fixed base to pass through the housing.

[0021] In one embodiment, the locking mechanism further includes a detection component for detecting the rotation angle of the fixed plate.

[0022] In one embodiment, the detection component includes a magnet and a Hall sensor. The magnet is disposed on the fixed plate and rotates with the fixed plate. The Hall sensor is disposed on the housing and is used to detect the magnetic field generated by the magnet.

[0023] In the technical solution of this utility model, the locking mechanism includes a fixed base, within which an adjusting column is slidably disposed. One end of the adjusting column is a locking end, used to connect the component to be fixed. An adjusting structure drives the adjusting column to move within the fixed base, adjusting the length of the locking end extending beyond the fixed base, i.e., adjusting the distance between the locking end and the component to be fixed. The adjusting structure drives the adjusting column to have a locked position and an unlocked position. In the locked position, the locking end of the adjusting column extends a longer length beyond the fixed base for connection with the component to be fixed. Since the fixed base is mounted on the housing, the adjusting column keeps the component to be fixed relatively stationary with respect to the housing, effectively restricting the movement of the component, providing stable support and limiting, and preventing displacement or damage to the component during transportation due to vibration or collision. When it is necessary to move the component to be fixed, the adjusting column can be used to... The adjusting structure drives the adjusting column to the unlocked position, shortening the distance the locking end extends from the fixed seat. This separates the locking end from the component to be fixed, allowing the component to remain movable inside the housing. Through the cooperation of the adjusting column and the adjusting structure, both movable and locked states of the component to be fixed can be achieved. Since the adjusting column is installed through the fixed seat, the adjusting structure can be adjusted from outside the housing, eliminating the need for complex disassembly to open the housing and operate on the component inside. This allows for easy fixing and releasing operations, improving work efficiency. Although the adjusting column extends through the housing, when not in use, the locking end can be shortened to not affect the movement of the component to be fixed. This minimizes the space occupied inside the housing, ensuring the rationality and compactness of the internal layout of the equipment or module, without increasing the external size of the equipment.

[0043] This utility model proposes a locking mechanism.

[0044] Please see Figure 1 , Figure 2 and Figure 4 In one embodiment of this utility model, the locking mechanism 10 is used to lock or release the component 21 to be fixed inside the housing 20. The locking mechanism 10 includes:

[0045] Mounting bracket 100 is used to connect the housing 20;

[0046] The adjusting column 200 passes through the fixed base 100 and is slidably connected to the fixed base 100. The locking end of the adjusting column 200 extends into the interior of the housing 20.

[0047] The adjusting structure 300 is driven to connect with the adjusting column 200, so that the length of the locking end of the adjusting column 200 extending out of the fixing seat 100 is adjustable, so that the locking end of the adjusting column 200 is in the locked position or the unlocked position; in the locked position, the adjusting column 200 is connected to the component 21 to be fixed, and in the unlocked position, the adjusting column 200 is separated from the component 21 to be fixed.

[0048] In the technical solution of this utility model, the locking mechanism 10 includes a fixed base 100, and an adjusting column 200 is slidably disposed within the fixed base 100. One end of the adjusting column 200 is a locking end, used to connect with the component 21 to be fixed. The adjusting structure 300 drives the adjusting column 200 to move within the fixed base 100 to adjust the length of the locking end of the adjusting column 200 extending out of the fixed base 100, that is, to adjust the distance between the locking end and the component 21 to be fixed. The adjusting structure 300 drives the adjusting column 200 to achieve the desired locking mechanism. There are locked and unlocked positions. In the locked position, the locking end of the adjusting column 200 extends a longer length beyond the fixing seat 100 for connection with the component 21 to be fixed. Since the fixing seat 100 is mounted on the housing 20, the adjusting column 200 keeps the component 21 to be fixed relatively stationary with respect to the housing 20, effectively limiting the movement of the component 21, providing stable support and limiting, and preventing displacement or damage to the component 21 due to vibration or collision during transportation. When it is necessary to move the component 21... At 21 o'clock, the adjusting column 200 is moved to the unlocked position by the adjusting structure 300, and the distance of the locking end extending out of the fixing seat 100 is shortened, so that the locking end is separated from the part to be fixed 21. The part to be fixed 21 can remain in an active state inside the housing 20. Through the cooperation of the adjusting column 200 and the adjusting structure 300, the part to be fixed 21 can be in both active and locked states. Since the adjusting column 200 is installed through the fixing seat 100, the adjusting structure 300 can adjust the adjusting column 200 from outside the housing 20. There is no need for complicated disassembly to open the housing 20 to operate the part to be fixed inside. The fixing and releasing operations can be easily completed, improving work efficiency. Although the adjusting column 200 extends through the housing 20, when not in use, the locking end can be shortened to not affect the movement of the part to be fixed 21. This can minimize the space occupied inside the housing 20, ensure the rationality and compactness of the internal layout of the equipment or module, and will not increase the external volume of the equipment.

[0049] Specifically, the locking mechanism 10 can be applied to some precision instruments, electronic devices or medical devices. Such devices have a housing 20, which contains a movable component 21 to be fixed. The component 21 needs to be in an active state during operation, but if it is allowed to move freely during transportation, it may be damaged by the vibration of the device. Therefore, during transportation, the locking mechanism 10 in this structure is used to fix the component 21 in the housing 20 to protect it from damage.

[0050] Please refer to Figure 4A fixing seat 100 is mounted on the housing 20 and extends through the housing 20. A movable cavity 101 is provided through the fixing seat 100, and the adjusting column 200 slides in the movable cavity 101. The material and shape of the fixing seat 100 are not limited. One end of the fixing seat 100 is configured as a locking end to be connected to the component 21 to be fixed. The locking end can extend out of the fixing seat 100 to cooperate with the component 21 to be fixed, or it can retract into the fixing seat 100 to separate from the component 21 to achieve two states of the component 21 to be fixed. In this embodiment, a connector 22 is provided in the housing 20 to be fixedly connected to the component 21 to be fixed. The connector 22 is provided with a connecting hole. In the locked state, the locking end extends out of the fixing seat 100 and the extension length is relatively long to be inserted into the connecting hole. The connector 22 is used to connect with the component 21 to be fixed, preventing the horizontal movement of the component 21 to be fixed.

[0051] In an embodiment of this utility model, the adjustment structure 300 includes:

[0052] The elastic element 310 is provided in the fixed base 100. The elastic element 310 is in a compressed state so as to have a restoring force that causes the adjusting column 200 to tend to move away from the part 21 to be fixed.

[0053] Two card slots 320 are provided. The card slots 320 are located on the fixed base 100, and the two card slots 320 are at different heights. One of the two card slots 320 forms a locking position, and the other of the two card slots 320 forms an unlocking position.

[0054] A crossbar 330 is installed at an adjusting column 200;

[0055] The adjusting column 200 moves toward the component 21 to be fixed against the elastic force of the elastic member 310 and can rotate so that the crossbar 330 is engaged in one of the two locking positions 320 under the elastic force of the elastic member 310.

[0056] Specifically, please refer to Figure 1 , Figure 2 and Figure 3The adjustment structure 300 includes an elastic element 310, a locking position 320, and a crossbar 330. The elastic element 310 is disposed in the movable cavity 101, with one end fixedly connected to the inner wall of the movable cavity 101 of the fixed seat 100, and the other end extending upward to connect with the adjustment column 200. In one embodiment, the elastic element 310 is a compression spring. When the elastic element 310 is in a compressed state, since the fixed seat 100 is fixed on the housing 20, the elastic element 310 has a tendency to rebound, which also has a tendency to drive the adjustment column 200 to move away from the part 21 to be fixed. Two crossbars are provided on the fixed seat 100. Different height locking positions 320 and crossbars 330 are set on the adjusting column 200 and cooperate with different locking positions 320 so that the adjusting column 200 is at different heights, that is, corresponding to the locking position and the unlocking position. The adjusting column 200 moves towards the part 21 to be fixed in the movable cavity 101 against the elastic force of the compression spring, and is locked in one locking position 320 by the crossbar 330 to realize the connection between the locking end and the connecting piece 22. By rotating the adjusting column 200, the crossbar 330 is rotated and locked into another locking position 320 to realize the separation between the locking end and the connecting piece 22.

[0057] In one embodiment, the adjustment structure 300 further includes a fixing plate 400, which is disposed at the end of the adjustment column 200 away from the component 21 to be fixed. The elastic member 310 is sleeved on the outer periphery of the adjustment column 200, with one end connected to the fixing seat 100 and the other end abutting against the side of the fixing plate 400 facing the fixing seat 100.

[0058] Specifically, please refer to Figure 1 , Figure 2 and Figure 3 The cross-section of the adjusting column 200 is smaller than that of the fixed plate 400. The elastic element 310 is a compression spring. The compression spring is sleeved on the outer periphery of the adjusting column 200. One end is fixedly connected to the inner wall of the fixed seat 100 inside the fixed seat 100, and the other end is connected to the side of the fixed plate 400 facing the fixed seat 100. When the adjusting column 200 is rotated to the locking position 320 of the unlocking position, the elastic element 310 rebounds, causing the fixed plate 400 to move away from the fixed seat 100. The fixed plate 400 drives the adjusting column 200 to move together in the direction away from the fixed seat 100, that is, the adjusting column 200 moves away from the part to be fixed 21, thus realizing the separation from the part to be fixed 21.

[0059] In one embodiment, please refer to Figure 2The fixing base 100 includes a base body 110 and a cylinder body 120 connected to each other. The base body 110 is mounted on the housing 20. The cylinder body 120 is located inside the housing 20 closer to the component 21 to be fixed. The base body 110 has a first cavity, and the cylinder body 120 has a second cavity. The first cavity and the second cavity are coaxially arranged and connected to form a movable cavity 101. The inner diameter of the first cavity is larger than the inner diameter of the second cavity to form a stepped structure at the base body 110 and the cylinder body 120. An elastic member 310 is disposed in the first cavity, with its bottom connected to the top of the cylinder body 120. The top of the elastic member 310 is connected to the bottom of the fixing plate 400. The space between the fixing plate 400 and the top of the cylinder body 120 is the movable space of the elastic member 310.

[0060] In one embodiment, the adjusting column 200 is a cylindrical structure, and the first cavity and the second cavity are respectively set to have a circular cross-section, so as to facilitate the rotation of the adjusting column 200 in the movable cavity 101.

[0061] In an embodiment of this utility model, the fixing plate 400 and the adjusting column 200 are connected by screws 500.

[0062] Specifically, please refer to Figure 2 The screw 500 passes downward through the fixing plate 400 and the adjusting column 200 in sequence to connect the fixing plate 400 and the adjusting column 200 into one unit. This allows the adjusting column 200 to move when the elastic element 310 drives the fixing plate 400 to move. If it is necessary to press down or rotate the adjusting column 200, the screw 500 can be operated with a wrench. In this embodiment, the screw 500 is an internal hex screw 500, and an internal hex wrench can be used accordingly. By rotating the internal hex screw 500 with the internal hex wrench, the crossbar 330 is rotated to engage with one of the two locking positions 320. The screw 500 not only stably connects the fixing plate 400 and the adjusting column 200, but also allows the adjusting column 200 to be rotated by turning the screw 500 with a wrench, making it easier to use force and operate. The type of screw 500 is not limited, as long as it can achieve a stable connection between the fixing plate 400 and the adjusting column 200.

[0063] In one embodiment, please refer to Figure 4 A rubber plug 23 is provided on the outside of the housing 20. When the adjusting column 200 does not need to be rotated, it is blocked at the screw 500. When the screw 500 needs to be rotated, the rubber plug 23 is removed.

[0064] In an embodiment of this utility model, the two slots 320 are respectively configured as a first slot 321 and a second slot 322. The first slot 321 and the second slot 322 are spaced apart and extend from the end of the fixing base 100 near the part to be fixed 21 to the end away from the part to be fixed 21.

[0065] The height of the first card slot 321 is greater than the height of the second card slot 322.

[0066] Specifically, please refer to Figure 2 and Figure 3 Two locking positions 320 at different heights are configured as a first locking groove 321 and a second locking groove 322 at different heights. Both the first locking groove 321 and the second locking groove 322 are located on the outer peripheral wall of the cylinder 120 and extend upwards from the bottom, i.e., the end near the component to be fixed 21 extends towards the end of the base 110. The bottoms of both the first locking groove 321 and the second locking groove 322 extend to the bottom of the cylinder 120, and the top of the first locking groove 321 is higher than the top of the second locking groove 322. It should be noted that there are two of each type of locking groove, and the two first locking grooves 321 and the two second locking grooves 322 are symmetrically arranged on the cylinder 120. This can be understood as the first locking grooves 321 and the second locking grooves 322 being spaced apart. In this embodiment, by pressing down and rotating the adjusting column 200, the two ends of the crossbar 330 on the adjusting column 200 are engaged with either the first locking groove 321 or the second locking groove 322. When the crossbar 330 is engaged in the second slot 322, because the top of the second slot 322 is low and the cylinder 120 prevents the crossbar 330 from moving upward with the elastic force of the elastic element 310, the locking end of the adjusting column 200 extends a long enough to be inserted into the connecting hole of the connector 22, thus locking the component 21 to be fixed. When it is necessary to move the component 21 to be fixed, the adjusting column 200 is pressed down in the direction of the component 21 to be fixed, so that the adjusting column 200... 00 disengages from the second slot 322. Then, rotate the adjusting column 200 so that the crossbar 330 on the adjusting column 200 is engaged in the first slot 321. Since the top of the first slot 321 is higher, the elastic member 310 rebounds, causing the fixing plate 400 and the adjusting column 200 to move upward. At this time, the crossbar 330 moves upward in the first slot 321, shortening the extension length of the locking end. The locking end rises away from the connecting member 22, so that the part to be fixed 21 is in an active state.

[0067] In one embodiment, the cylinder 120 has a cylindrical structure, and the adjacent first slot 321 and second slot 322 are spaced 90 degrees apart, that is, the two first slots 321 and the two second slots 322 are distributed in a 360° circular shape. When rotating the adjusting column 200, rotating it 90° will rotate the adjusting column 200 to the locked position or the unlocked position.

[0068] In an embodiment of this utility model, the adjusting column 200 is provided with a through hole 210 in the radial direction, the crossbar 330 is provided in the through hole 210, and the two ends of the crossbar 330 protrude from the through hole 210 and are engaged with the first slot 321 / second slot 322.

[0069] Specifically, please refer to Figure 2 and Figure 3 The crossbar 330 is set horizontally in the through hole 210, and both ends protrude from the through hole 210 so that the two ends can be engaged in the first slot 321 or the second slot 322, so that the adjusting column 200 is in the unlocked position or the locked position.

[0070] In one embodiment, the first slot 321 and the second slot 322 can be disposed on the inner peripheral wall of the cylinder 120, and the crossbar 330 is engaged in the first slot 321 or the second slot 322 in the second cavity. In another embodiment, namely this solution, the first slot 321 and the second slot 322 can be disposed on the peripheral wall of the cylinder 120 and penetrate through the peripheral wall to communicate with the second cavity, which can also realize the engagement of the crossbar 330. Moreover, this solution is lighter in weight, which facilitates the lightweighting of the structure.

[0071] In an embodiment of this utility model, the locking mechanism 10 further includes a limiting structure. The limiting structure is disposed on the fixed seat 100 and cooperates with the housing 20 to restrict the rotation of the fixed seat 100. The setting of the limiting structure allows the fixed seat 100 to rotate within the limiting space formed by the limiting structure, avoiding excessive rotation and affecting the operation time.

[0072] In one embodiment, the limiting structure is configured as a limiting post 600, which extends toward a direction away from the fixed base 100 to pass through the housing 20.

[0073] Specifically, please refer to Figure 1 and Figure 4 At least two limiting posts 600 are provided above the fixed base 100, and at least two limiting holes are provided on the housing 20 accordingly. The fixed base 100 is installed on the inner wall of the housing 20, and each limiting post 600 is inserted upward into the corresponding limiting hole. When the adjusting column 200 is rotated, the limiting posts 600 can prevent the fixed base 100 from rotating with it. The first slot 321 and the adjacent second slot 322 are set between the two limiting posts 600. Since the fixed plate 400 is installed on the adjusting column 200 and rotates with the adjusting column 200, the two limiting posts 600 can block the rotation of the fixed plate 400. That is, the limiting posts 600 limit the rotation of the adjusting column 200, avoid excessive rotation, and improve operating efficiency.

[0074] In an embodiment of this utility model, the locking mechanism 10 further includes a detection component 700. The detection component 700 is used to detect the rotation angle of the fixed plate 400. Since the fixed plate 400 rotates together with the adjusting column 200, the detection component 700 detects the rotation angle of the fixed plate 400, which is the same as detecting the rotation angle of the adjusting column 200. The required angle can be precisely rotated so that the crossbar 330 is engaged in the first slot 321 or the second slot 322, avoiding excessive rotation and reducing working time.

[0075] In an embodiment of this utility model, the detection component 700 includes a magnet 710 and a Hall sensor 720. The magnet 710 is disposed on the fixed plate 400 and rotates with the fixed plate 400. The Hall sensor 720 is disposed on the housing 20 and is used to detect the magnetic field generated by the magnet 710.

[0076] Specifically, please refer to Figure 1 Magnet 710 is installed at the end of fixed plate 400 away from adjusting column 200, and Hall sensor 720 is installed on housing 20. Hall sensor 720 detects the magnetic field generated by magnet 710 to determine the rotation angle of fixed plate 400. If magnet 710 enters the sensing range of Hall sensor 720, adjusting column 200 rotates to the locked position. If magnet 710 leaves the sensing range of Hall sensor 720, adjusting column 200 rotates to the unlocked position. The setting of Hall sensor 720 and magnet 710 allows for measurement without contact, extending service life. Furthermore, the Hall effect is sensitive to changes in magnetic field, enabling high-precision position detection.

[0077] In one embodiment, the Hall sensor 720 may be a photoelectric sensor. Photoelectric sensors are provided at both the locked and unlocked positions of the fixed plate 400 to detect whether the fixed plate 400 has reached the locked or unlocked position.

[0078] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
