Description

Technical Field

[0002] In the related art, some devices have window structures such as observation ports, inspection ports, and charging ports, and these structures have corresponding cover. Generally speaking, the cover has a sandwich structure with two layers of plates stacked together.

[0042] Traditional quick-release locks are only suitable for fixing sandwich structures that fit double-layer panels, and are not suitable for structures with gaps between panels, resulting in limited application scenarios.

[0043] In response to the above problems, the embodiments of the present application provide a lock, a connection assembly and their application, which can fix two layers of plates with a gap, have a simple structure, are quick and easy to disassemble, and achieve reliable fixation.

[0044] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0045] See also Figures 1 to 4 The lock 10 provided in the embodiment of the present application can be used to connect the first plate 20 and the second plate 30. The lock 10 includes a lock body 110, a block 120, a lock core 130 and a limiter 140. Among them:

[0046] The lock body 110 is used to connect the first plate body 20 and the second plate body 30 respectively; the lock body 110 includes a fixed portion 111 and a movable portion 112 along the axial direction, the end of the fixed portion 111 is exposed on the side of the first plate body 20 away from the second plate body 30, the end of the movable portion 112 is exposed on the side of the second plate body 30 away from the first plate body 20 and elastically abuts against the second plate body 30, and has corresponding retraction structure 112A and expansion structure 112B; the lock body 110 is provided with an accommodating cavity 113 along the axial direction and a first limiting hole 114 along the radial direction, and the first limiting hole 114 is connected to the accommodating cavity 113.

[0047] The stopper 120 is arranged on a side of the first plate 20 away from the second plate 30 and is detachably connected to the fixing portion 111 of the lock body 110 . The stopper 120 defines a second limiting hole 121 which communicates with the accommodating cavity 113 .

[0048] The lock core 130 is movably inserted into the second limiting hole 121 of the block 120 and the accommodating cavity 113 of the lock body 110, and the lock core 130 has a locking position 130B and an unlocking position 130A in the accommodating cavity 113; the lock core 130 is provided with a locking groove 131 and an unlocking groove 132, and the locking groove 131 and the unlocking groove 132 are respectively connected to the first limiting hole 114.

[0049] The limiting member 140 is respectively inserted through the first limiting hole 114 and the locking slot 131 or the unlocking slot 132 to restrict the lock core 130 from switching between the locked position 130B and the unlocked position 130A. When the limiting member 140 is correspondingly inserted through the first limiting hole 114 and the locking slot 131, the movable portion 112 is in an expanded configuration 112B, and the lock core 130 is in the locked position 130B. When the limiting member 140 is correspondingly inserted through the first limiting hole 114 and the unlocking slot 132, the movable portion 112 is in a collapsed configuration 112A, and the lock core 130 is in the unlocked position 130A.

[0050] It is understandable that Figure 2 and Figure 4As shown, the first plate 20 and the second plate 30 are spaced apart in the axial direction. The first plate 20 and the second plate 30 are respectively connected by the lock body 110, so that the first plate 20 and the second plate 30 can be arranged coaxially. The lock body 110 includes a fixed portion 111 and a movable portion 112 that are continuously connected in the axial direction. The accommodating cavity 113 axially connects the fixed portion 111 and the movable portion 112. The lock core 130 is inserted into the accommodating cavity 113 and is detachably connected to the lock body 110 via a stopper 140. Specifically, the fixed portion 111 is correspondingly connected to the first plate 20, so that the position of the lock body 110 relative to the first plate 20 is determined and the connection with the first plate 20 is maintained. The end of the movable portion 112 exposed from the second plate 30 elastically abuts against the second plate 30. The structural type of the movable portion 112 is switched by changing the position of the lock core 130 within the accommodating cavity 113 of the movable portion 112. The position of the lock core 130 within the accommodating cavity 113 can be changed by changing the position of the limiting member 140. When the limiting member 140 penetrates the first limiting hole 114 of the lock body 110 and the locking groove 131 of the lock core 130, the position of the lock core 130 within the accommodating cavity 113 is fixed, that is, the lock core 130 is located in the locked position 130B. At the same time, the lock core 130 presses the movable portion 112 from the inside to the outside, causing the movable portion 112 to assume an expanded structure 112B. The end of the movable portion 112 tightly abuts the second plate 30, forcing the second plate 30 to be fixed to the movable portion 112 and unable to move, thereby maintaining the relative position of the first plate 20 and the second plate 30 fixed, forming a locked state. On the contrary, when the limiting member 140 passes through the first limiting hole 114 of the lock body 110 and the unlocking groove 132 of the lock core 130, the lock core 130 moves in the position within the accommodating cavity 113, that is, the lock core 130 is located in the unlocking position 130A, and the lock core 130 no longer squeezes the movable part 112, so that the movable part 112 is in a relaxed and retracted structure 112A, and the end of the movable part 112 freely abuts the second plate body 30, so that the second plate body 30 can move freely along the movable part 112, thereby keeping the relative positions of the first plate body 20 and the second plate body 30 free to change, forming an unlocked state.

[0051] The lock 10 of this embodiment restricts the position of the lock core 130 relative to the accommodating cavity 113 of the lock body 110 by means of a position-limiting member 140, allowing the lock core 130 to move between an unlocked position 130A and a locked position 130B, thereby changing the structure of the movable portion 112 of the lock body 110, causing the movable portion 112 to switch between a retracted configuration 112A and an expanded configuration 112B, thereby achieving a fixed position and a change in the relative position of the lock body 110 relative to the first plate 20 and the second plate 30, thereby achieving locking and unlocking of the lock 10. The lock 10 of this application has a simple structure, is convenient and quick to operate, and achieves rapid unlocking and locking, and can be widely used for fixing and unlocking between spaced plates.

[0052] In order to facilitate the installation of the lock 10 of the present application, Figure 1 and Figure 2 As shown, the first plate 20 defines a first through-hole 210, and the second plate 30 defines a second through-hole 310 corresponding to the first through-hole 210. Preferably, the first through-hole 210 and the second through-hole 310 are coaxially arranged. In some embodiments, the lock body 110 is configured to be inserted into the first through-hole 210; the outer diameter of the stopper 120 is larger than the diameter of the first through-hole 210. With this arrangement, after the lock body 110 is inserted into the first through-hole 210, the fixing portion 111 of the lock body 110 is at least partially exposed from the first plate 20. The stopper 120 is detachably connected to the exposed fixing portion 111. When connected, the fixing portion 111 can be fixed to the first plate 20, preventing the lock body 110 from separating from the first plate 20. In some embodiments, the stopper 120 can be screwed or snap-fitted to the fixing portion 111 of the lock body 110, thereby achieving a detachable effect. When the lock 10 and the first plate 20 need to be separated, the stopper 120 can be removed to achieve separation of the lock 10 and the first plate 20 .

[0053] Furthermore, if Figure 4 and Figure 5 As shown, in order to ensure a stable connection between the lock body 110 and the first plate 20 in actual use, in some embodiments, the fixing portion 111 of the lock body 110 is provided with a first boss 1111 in the radial direction, so that the outer diameter of the fixing portion 111 is larger than the first through hole 210. The first boss 1111 is arranged on a side of the first plate 20 close to the second plate 30 and abuts against the first plate 20. In other words, the first plate 20 is clamped on both sides by the stopper 120 and the first boss 1111, respectively, thereby firmly connecting the first plate 20 to the lock body 110.

[0054] In order to ensure that the lock 10 of the present application can unlock and fix the first plate 20 and the second plate 30, as shown in FIG. Figure 2 and Figure 4As shown, in some embodiments, the outer diameter of the collapsed structure 112A of the movable portion 112 of the lock body 110 is less than or equal to the diameter of the second through hole 310, while the outer diameter of the expanded structure 112B of the movable portion 112 exposed from the second plate 30 is greater than the diameter of the second through hole 310, and the expanded structure 112B abuts against the sidewall of the second through hole 310. In other words, when the movable portion 112 is in the collapsed structure 112A, the outer diameter of the collapsed structure 112A is no greater than the diameter of the second through hole 310, allowing the second plate 30 to be freely separated from the movable portion 112. When the movable portion 112 is in the expanded structure 112B, the outer diameter of the end of the movable portion 112 exposed from the second plate body 30 is larger than the aperture of the second through hole 310, ensuring that the second plate body 30 will not separate from the lock body 110; at the same time, the outer periphery of the expanded structure 112B tightly abuts against the side wall of the second through hole 310, preventing the second plate body 30 from sliding along the lock body 110, that is, the second plate body 30 is fixed to the lock body 110 by friction, thereby achieving a locking effect.

[0055] Furthermore, in order to make the lock body 110 have the folding structure 112A and the expanding structure 112B, as shown in FIG. Figure 5 and Figure 6 As shown, in some embodiments, the sidewall of the movable portion 112 includes multiple elastic pieces 1121 along the axial direction. Each elastic piece 1121 includes an abutting portion 1122 and a stop portion 1123. The outer diameter of the stop portion 1123 is larger than the outer diameter of the abutting portion 1122, and the stop portion 1123 is exposed on the side of the second plate 30 away from the first plate 20. When the movable portion 112 is in the expanded structure 112B, the outer diameter of the stop portion 1123 is larger than the aperture of the second through hole 310, and the abutting portion 1122 abuts the second plate 30. In other words, the multiple elastic pieces 1121 are independently provided and together enclose the movable portion 112 and a portion of the accommodating cavity 113. By squeezing the multiple elastic pieces 1121 from the inside out, the multiple elastic pieces 1121 can be expanded in all directions, thereby forming the expanded structure 112B. Accordingly, when the pressure is removed, the multiple spring pieces 1121 return to their original state, i.e., the collapsed configuration 112A. Preferably, by designing abutment portions 1122 and stopper portions 1123 on the spring pieces 1121, with the stopper portions 1123 exposed outside the second plate 30, the second plate 30 is prevented from separating in the expanded configuration 112B. Furthermore, the abutment portions 1122 abut the inner wall of the second through hole 310, preventing the second plate 30 from sliding axially along the movable portion 112, thereby securing the second plate 30. Preferably, the stopper portions 1123 may be barbed hooks.

[0056] In order to make the movable portion 112 of the lock body 110 easier to expand and ensure reliability, as Figure 6As shown, in some embodiments, a gap 115 is provided between two adjacent spring pieces 1121, and a crack-stopping hole 116 is provided at one end of the gap 115 away from the second plate 30. In some embodiments, the number of spring pieces 1121 can be 3 to 8, and the distance between the gaps 115 between two adjacent spring pieces 1121 can be 0.4 mm to 1.0 mm. Preferably, the multiple spring pieces 1121 can be arranged into a structure similar to a triangle, a quadrilateral, a pentagon, a hexagon, an octagon, or the like. Furthermore, by providing a crack-stopping hole 116 at one end of the gap 115, on the one hand, it facilitates the expansion of the spring pieces 1121, and on the other hand, it prevents stress concentration in the movable portion 112 after forming the expanded structure 112B, thereby improving the durability and reliability of the structure. Preferably, in order to simplify the structure, in one embodiment, the lock body 110 can be an integrally molded structure, that is, the fixed portion 111 and the movable portion 112 are integrally molded. To improve durability, for example, the lock body 110 can be made of metal, such as titanium alloy, aluminum alloy, stainless steel, etc., which is not limited here.

[0057] The position-limiting member 140 can actively shift its position between the unlocking slot 132 and the locking slot 131, or it can passively shift its position between the unlocking slot 132 and the locking slot 131. When the position of the position-limiting member 140 is shifted passively, in some embodiments, the unlocking slot 132 and the locking slot 131 are interconnected, and a driving structure 133 is provided at one end of the lock core 130 close to the first plate 20 to adjust the movement of the position-limiting member 140 between the locking slot 131 and the unlocking slot 132 according to the driving structure 133. For example, the locking slot 131 and the unlocking slot 132 are arranged in an L-shape or a T-shape, wherein the locking slot 131 is arranged horizontally and the unlocking slot 132 is arranged vertically. For another example, the driving structure 133 can be a triangular groove structure, a hexagonal groove structure, etc. These structures can be the structure of the head of a bolt or screw, so that it is convenient to use a tool such as a screwdriver to drive the lock core 130 to rotate clockwise or counterclockwise. For example, when the lock cylinder 130 is driven to rotate counterclockwise, the locking groove 131 of the lock cylinder 130 shifts to abut against the limiting member 140. The limiting member 140 now corresponds to the first limiting hole 114 and the locking groove 131 provided through the lock body 110. When the lock cylinder 130 is driven to rotate clockwise, the unlocking groove 132 shifts to abut against the limiting member 140. The limiting member 140 now corresponds to the first limiting hole 114 and the unlocking groove 132 provided through the lock body 110. In other words, the corresponding positional relationship between the limiting member 140 and the unlocking groove 132 and the locking groove 131 can be switched without moving the position of the limiting member 140. In other embodiments, when the position of the limiting member 140 is adjusted actively, the position of the limiting member 140 can be actively adjusted to correspond to the unlocking groove 132 or the locking groove 131 provided through the lock body 110.

[0058] When the limit member 140 is located in the unlocking groove 132, the lock core 130 can move freely in the accommodating cavity 113 relative to the lock body 110. By pulling up the lock core 130 axially, the lock core 130 can be disengaged from the accommodating cavity 113 of the lock body 110, thereby realizing unlocking between the first plate body 20 and the second plate body 30.

[0059] In order to improve the stability of the limiting member 140 on the lock core 130, the number of limiting members 140 can be two or more. Accordingly, the number of unlocking grooves 132 is set accordingly, and the number of locking grooves 131 is set accordingly. By increasing the number, it can be ensured that when one of the limiting members 140 is damaged, the other limiting members 140 still have a limiting effect. Preferably, each unlocking groove 132 is symmetrically distributed along the axis of the lock core 130, and the locking groove 131 is correspondingly opened. The lock body 110 is symmetrically opened with a corresponding number of first limiting holes 114, and each limiting member 140 is symmetrically penetrated, thereby evenly dispersing the force on the lock body 110 and improving its service life.

[0060] In order to realize automatic unlocking of the lock cylinder 130, as Figure 2 and Figure 6 As shown, in some embodiments, the lock 10 further includes an elastic member 150, which is disposed within the accommodating cavity 113 and axially abuts the lock core 130. Preferably, the elastic member 150 may be a spring, a torsion spring, or the like. Furthermore, to facilitate the elastic member 150 in causing the lock core 130 to rebound, in some embodiments, a second boss 134 is radially provided on the outer side of the end of the lock core 130 proximate the first plate 20, and a third boss 1112 is radially provided within the accommodating cavity 113 of the fixed portion 111. One end of the elastic member 150 elastically abuts the second boss 134, while the other end of the elastic member 150 elastically abuts the third boss 1112. When the stopper 140 is located in the locking groove 131, the lock core 130 penetrates the accommodating cavity 113 and presses against the movable portion 112 of the lock body 110. Simultaneously, the elastic member 150 is axially compressed by the lock core 130 within the accommodating cavity 113 between the second boss 134 and the third boss 1112. When the limiting member 140 is located in the unlocking groove 132 , the elastic member 150 elastically stretches and elastically abuts against the second boss 134 , causing the lock core 130 to bounce up in the axial direction in the opposite direction, thereby achieving automatic unlocking of the lock core 130 .

[0061] In order to determine the position of the lock core 130 in the accommodating cavity 113 of the lock body 110 in the locked state, it is ensured that the lock core 130 reaches the locked position 130B, such as Figure 4 and Figure 6As shown, in some embodiments, a second boss 134 is radially disposed on the outer side of one end of the lock core 130 proximate to the first plate 20. The stopper 120 is provided with a fourth boss 122 protruding from the wall of the second limiting hole 121, with the second boss 134 abutting against the fourth boss 122. In other words, when the lock core 130 moves axially within the accommodating cavity 113 of the lock body 110, the lock core 130 is determined to have reached the locked position 130B when the second boss 134 of the lock core 130 abuts against the fourth boss 122 of the stopper 120. Preferably, to prevent the fourth boss 122 from obstructing the extension of the elastic member 150, the radial width of the fourth boss 122 is smaller than the radial width of the second boss 134. To ensure the aesthetic appearance of the lock 10 in practical applications, the axial thickness of the stopper 120 should not be excessive. In some embodiments, the thickness of the stopper 120 is equal to the thickness of the fixed portion 111 of the lock body 110 exposed from the first plate 20 in the locked state.

[0062] To accurately position the lock cylinder 130 within the accommodating cavity 113, in some embodiments, a retaining member 140 is disposed through the first retaining hole 114 and is screwed or snap-fitted to the lock body 110. Specifically, threads can be provided on the inner wall of the first retaining hole 114, and threads can be provided on the outer periphery of the retaining member 140, allowing the retaining member 140 to be screwed to the lock body 110 within the first retaining hole 114. Alternatively, threads are not required, and the retaining member 140 can be connected to the lock body 110 via a snap-fit ​​connection.

[0063] It should be noted that the lengths of the lock body 110 and the lock core 130 can be designed accordingly based on the change in the spacing between the first plate 20 and the second plate 20, and in particular, the length of the movable portion 112 of the lock body 110 can be adjusted accordingly. Similarly, when the diameters of the first through hole 210 and the second through hole 310 change, the diameters of the stopper 120, the lock body 110, and the lock core 130, in particular, the diameter of the expansion structure 112B of the lock body 110, can be designed accordingly.

[0064] The following describes the installation, locking, unlocking and disassembly of the lock 10 on the first plate 20 and the second plate 30 according to the present embodiment with reference to the accompanying drawings.

[0065] 1. Installation of lock 10:

[0066] First, each limiting member 140 is inserted into each corresponding first limiting hole 114 of the lock body 110 and fixed therein. Then, the lock body 110 is inserted into the first through hole 210 of the first plate 20 and the second through hole 310 of the second plate 30. The first boss 1111 of the lock body 110 abuts the side of the first plate 20 facing the second plate 30. The end of the fixed portion 111 of the lock body 110 is exposed from the first plate 20, and the end of the movable portion 112 is exposed from the second plate 30. After the elastic member 150 is placed in the mounting cavity of the lock body 110, the stopper 120 is sleeved onto the end of the lock body 110 exposed from the first plate 20. The stopper 120 and the lock body 110 are screwed and fixed. The first plate 20 is clamped and fixed by the stopper 120 and the first boss 1111. Finally, the lock core 130 is passed through the second limiting hole 121 of the block 120, the elastic member 150 and the accommodating cavity 113 of the lock body 110 in sequence, and the limiting member 140 is axially passed through the unlocking groove 132 of the lock core 130 to achieve the installation of the lock 10 on the first plate body 20 and the second plate body 30. At this time, the lock 10 is in the unlocked state, the lock core 130 is located in the unlocking position 130A of the accommodating cavity 113, and the limiting member 140 is passed through the first limiting hole 114 and the unlocking groove 132. The movable part 112 of the lock body 110 is in a retracted structure 112A.

[0067] 2. Locking of the lock 10

[0068] By pressing the lock core 130, the second boss 134 at the end of the lock core 130 is fully inserted into the stopper 120 and abuts against the fourth boss 122 on the inner side of the stopper 120, ensuring that the lock core 130 is inserted into the accommodating cavity 113 and reaches the locked position 130B. The lock core 130 applies force from the inside to the outside to squeeze the movable portion 112 of the lock body 110, causing the elastic pieces 1121 of the movable portion 112 to be stretched and expanded. The stopper 1123 of the elastic piece 1121 fully abuts the end of the second plate 30 away from the first plate 20, and the abutting portion 1122 of the elastic piece 1121 tightly abuts the inner wall of the second through hole 310 of the second plate 30, preventing the second plate 30 from moving axially. Finally, the lock core 130 is rotated using a tool such as a screwdriver, causing the position of the stopper 140 relative to the lock core 130 to change, and the stopper 140 is passively transferred from the unlocking slot to the locking slot 131. At this point, the lock 10 is in the locked state, with the first plate 20 and the second plate 30 positioned to secure the lock core 130 in the locked position 130B of the accommodating cavity 113. The stopper 140 is inserted through the first stopper hole 114 and the locking slot 131, and the movable portion 112 of the lock body 110 is in the expanded configuration 112B.

[0069] 3. Unlocking the lock 10

[0070] During the locking operation of the lock 10, the lock core 130 is rotated in the opposite direction, causing the position of the stopper 140 relative to the lock core 130 to change. The stopper 140 is passively transferred from the locking groove 131 to the unlocking groove 131. The elastic member 150 springs the lock core 130 axially along the accommodating cavity 113, automatically moving the lock core 130 from the locked position 130B to the unlocked position 130A within the accommodating cavity 113. The movable portion 112 of the lock body 110 loses internal compression, and the springs 1121 automatically return to the retracted configuration 112A. The stopper 1123 and abutment 1122 of the springs 1121 no longer abut the second plate 30. At this time, the lock 10 is in the unlocked state, the second plate 30 can be freely separated from the lock body 110, the lock core 130 is located in the locking position 130B of the accommodating cavity 113, the limiting member 140 is passed through the first limiting hole 114 and the locking groove 131, and the movable part 112 of the lock body 110 is in an expanded structure 112B.

[0071] 4. Disassembly of Lock 10

[0072] After unlocking, the second plate 30 and the lock core 130 can be freely removed, and finally the block 120 is disassembled and separated from the fixing portion 111 of the lock body 110, and the first plate 20 can be removed from the lock body 110, thereby completing the disassembly of the lock 10.

[0073] As can be seen from the above, the lock 10 of the present application has a compact structure, requires minimal installation space, is easy to assemble and disassemble, and offers reliable and durable performance. Furthermore, when used to unlock two plates spaced apart, the lock 10 of the present application can be disengaged along the axial direction and can limit the displacement of the two plates perpendicular to the axial direction.
