DETAILED DESCRIPTION

[0041] The utility model is further explained in detail below in combination with the drawings and examples. Same parts are indicated by same drawing reference in which. It is needful to explain that, the words "front", "back", "left", "right", "up" and "down" in the following description refer to the direction in the drawing, and the words "bottom surface" and "top surface", "inner" and "outer" refer to the direction towards or away from the geometric center of a particular part.

[0042] Referring to Figures 1-6 Fig. 1, a lock comprises a connecting seat 1, a lock beam 2 inserted into the connecting seat 1, a lock pin 11 and a driving member 12;

[0043] The connecting seat 1 is provided with an insertion hole 13 for inserting the lock beam 2 and a sliding groove 14 for sliding the lock pin 11;

[0044] The lock beam 2 is provided with a groove 21 corresponding to the position of the lock pin 11;

[0045] The lock pin 11 is located on one side of the lock beam 2;

[0046] The driving member 12 drives the locking pin 11 to disengage or engage the recess 21.

[0047] The locking beam 2 is inserted into the insertion hole 13 of the connecting seat 1, and the locking pin 11 slides along the sliding groove 14 under the driving of the driving member 12. When the locking pin 11 engages the recess 21 of the locking beam 2, the locking beam 2 is locked and cannot move. When the locking pin 11 disengages the recess 21, the locking beam 2 can move freely.

[0048] Compared with the prior art, the recess 21 is arranged on one side or both sides of the locking beam 2 in correspondence with the position of the locking pin 11.

[0049] As shown in Figure 2 and Figure 4 , the sliding groove 14 guides the locking pin 11 to move towards the recess 21 to engage or disengage the recess 21, thereby providing reliable positioning and reducing the required machining precision of the cooperation between the locking pin 11 and the recess 21.

[0050] The recess 21 can be designed in a shape (for example, rectangular or arc-shaped) matching the locking pin 11. Through the cooperation between the locking pin 11 and the recess 21, the problem of vibration loosening caused by the direct pressing of the locking pin 11 against the surface of the locking beam 2 is avoided.

[0051] Meanwhile, the recess 21 can be formed by milling or polishing the side surface of the locking beam 2. Compared with the process of forming the recess 21 or the through hole in the middle of the locking beam 2 in the prior art, the process of forming the recess 21 on the side surface is simple, the required cooperation precision of the recess 21 and the locking pin 11 is small, and the stability of the locking beam 2 when locked can be increased by arranging the locking pin 11 on both sides.

[0052] When the surface of the locking beam 2 has a certain curvature, it is difficult to drill a hole in the surface of the locking beam 2. The present solution can effectively avoid this problem by forming the recess 21 on the side surface through polishing and the like, thereby reducing the process difficulty.

[0053] The formation of the recess 21 or the through hole in the middle of the locking beam 2 requires drilling a hole corresponding to the size of the locking pin 11. If the size of the locking pin 11 is large, the recess 21 or the through hole on the locking beam 2 that matches the locking pin 11 will be too large, thereby weakening the structural strength of the locking beam 2.

[0054] If the recess 21 or the through hole on the locking beam 2 is small, the required cooperation precision between the locking pin 11 and the recess 21 or the through hole will be increased, and the locking pin 11 may not be smoothly inserted into the recess 21 or the through hole due to the deviation under various factors such as vibration or machining and installation.

[0055] Preferably, the connecting member 15 is further included.

[0056] The opening 31 of the sliding groove 14 corresponds to the side of the connecting seat 1, and the connecting piece 15 is provided with a limiting groove 151 corresponding to the position of the locking pin 11, and the locking pin 11 is provided with a connecting part 111 corresponding to the position of the limiting groove 151;

[0057] The limiting groove 151 is connected with the connecting part 111 to limit the locking pin 11 from being pulled out of the opening 31 of the sliding groove 14; the locking pin 11 is connected with the connecting piece 15 to form axial linkage through the cooperation of the connecting part 111 and the limiting groove 151.

[0058] As shown in Figure 3 and Figure 4 , when installed, the locking pin 11 is placed in the sliding groove 14, and then the connecting piece 15 is installed to limit the locking pin 11 from being pulled out, and as shown in Figure 3 , the locking pin 11 can be provided with an annular groove 21 (i.e. the connecting part 111) which cooperates with the limiting groove 151 of the connecting piece 15 to limit each other from being pulled out, thereby simplifying the overall installation steps of the lock;

[0059] Meanwhile, the connecting part 111 can also be provided as a protrusion inserted into the limiting groove 151, and as long as the connecting piece 15 can limit the locking pin 11 from being pulled out of the sliding groove 14, the cooperation mode can be applied in the utility model;

[0060] As shown in Figure 3 and Figure 4 , the driving piece 12 can be connected with the connecting piece 15, and the driving piece 12 drives the connecting piece 15 to indirectly drive the locking pin 11 to slide in the sliding groove 14, when the locking pin 11 is provided in multiple, the connecting piece 15 indirectly drives the locking pin 11, which can simplify the driving structure and does not need to increase the redundant structure for driving multiple locking pins 11;

[0061] Meanwhile, the driving piece 12 can directly drive the locking pin 11, and the connecting piece 15 only serves as a part for limiting the locking pin 11 from being pulled out.

[0062] Preferably, the number of the locking pin 11 is two, which are respectively located on both sides of the lock beam 2, and the connecting piece 15 is connected with the two locking pins 11 at the same time;

[0064] By arranging two locking pins 11 on both sides of the lock beam 2, the connecting piece 15 drives the two locking pins 11 at the same time, so that the lock beam 2 is subjected to symmetrical locking force, thereby avoiding the problem of unbalanced load when locking on one side and improving the balance and stability of the locking;

[0065] When the driving piece 12 drives the connecting piece 15 to move, the two locking pins 11 synchronously enter or pull out of the groove 21 of the lock beam 2, thereby ensuring the synchronization of the locking;

[0066] The double locking pin 11 design can maintain the locking state in a vibration or impact environment, reduce the risk of loosening, and reduce the load of a single locking pin 11, thereby prolonging the service life of the single locking pin 11.

[0067] Preferably, the driving member 12 is provided with a fixing member 121, and the connecting member 15 is provided with a fixing groove 152 accommodating the fixing member 121.

[0068] The fixing member 121 abuts against the fixing groove 152, and the driving member 12 drives the connecting member 15 to move.

[0069] As shown in Figure 3 and Figure 4 The abutment of the fixing member 121 and the fixing groove 152 enables the driving member 12 to directly drive the connecting member 15 to move and transmit driving force;

[0070] Meanwhile, the abutment connection can simplify the installation steps between the driving member 12 and the connecting member 15, and this connection is simple and reliable, facilitating assembly and maintenance;

[0071] The driving member 12 converts the rotational movement of the driving member 12 into the direct movement of the connecting member 15 through the cooperation of the fixing member 121 and the fixing groove 152, ensuring that the connecting member 15 moves synchronously with the driving member 12, thereby accurately controlling the position of the locking pin 11;

[0072] The abutment of the fixing member 121 and the fixing groove 152 can absorb part of the vibration energy and reduce the wear at the abutment.

[0073] Preferably, the connecting member 15 is arranged on both sides of the driving member 12 and is arranged in parallel.

[0074] The driving member 12 drives the connecting members 15 on both sides to move, and the moving directions of the connecting members 15 on both sides are opposite.

[0075] When the connecting member 15 is provided with multiple connecting members, the driving member 12 needs to drive the connecting members 15 on both sides simultaneously and in opposite directions, so that the locking pins 11 on both sides enter or leave the groove 21 simultaneously.

[0076] This design can reduce the required space in the moving direction of the connecting member 15, save space, and also improve the compactness of the structure, and simultaneously drive the connecting members 15 on both sides to enter or leave the groove 21 through the driving member 12.

[0077] Preferably, the first housing 3 and the plug member 4 are further included, and the connecting seat 1 is inserted into the first housing 3.

[0080] The pin 4 can be a pin or a bolt, which passes through the corresponding holes of the first housing 3 and the connecting seat 1 to connect the first housing 3 and the connecting seat 1. This threaded connection or pin design facilitates assembly and disassembly, while also ensuring the stability of the connecting seat 1.

[0081] The first housing 3 serves a protective function, preventing external foreign objects from entering and affecting the operation of the lock. The use of the pin 4 provides a reliable fixing method, preventing the connecting seat 1 from loosening in a vibrating environment.

[0082] Preferably, the first housing 3 is provided with an opening 31 for the connector 1 to be inserted, and the opening 31 is provided with a sealing member 5, which is used to seal the first housing 3.

[0083] The sealing component 5 seals the opening 31 of the first housing 3 to prevent dust, moisture, etc. from entering the interior of the first housing 3 and protect the internal components;

[0084] The sealing component 5 can be a cover plate or a sealing ring, which is fixed by bolts, snaps or adhesives, and cooperates with the first housing 3 to compensate for the sealing performance of the first housing 3.

[0085] During installation, the connector 1 is inserted through the opening 31 and then sealed with the sealing element 5 for easy maintenance and replacement. The sealing element 5 can be made of a material with waterproof or dustproof functions, which can extend the service life of the lock.

[0086] Preferably, it also includes a second housing 6 and a third housing 7, which are fitted onto the outside of the first housing 3 to protect the first housing 3.

[0087] like Figure 6 As shown, the second housing 6 and the third housing 7 are fitted over the outside of the first housing 3, providing an additional protective layer to prevent environmental factors such as physical impact and corrosion from affecting the first housing 3 and internal components;

[0088] The second housing 6 and the third housing 7 can be made of metal or plastic and are installed by a sleeve method;

[0089] In one embodiment, the second housing 6 is fitted onto the first housing 3, and the third housing 7 is fitted onto the second housing 6, forming a multi-layer protection mechanism to prevent damage to the core inside the lock and extend its service life.

[0090] In another embodiment, the second housing 6 and the third housing 7 cooperate to form a protective shell outside the first housing 3, such as... Figure 6As shown, this way can avoid the installation cumbersome and increase the size of the lock brought by the multi-layer shell nesting, but also can protect the first shell 3, thereby improving the durability and adaptability of the lock, suitable for harsh environments.

[0091] Preferably, the second shell 6 is snap connected with the third shell 7.

[0092] As shown, the second shell 6 and the third shell 7 are snap connected, and the second shell 6 and the third shell 7 can be quickly assembled and disassembled without tools, improving the maintenance efficiency. Figure 6

[0093] At the same time, the snap connection reduces the use of fasteners such as bolts, reducing weight and cost.

[0094] Preferably, it also includes a fourth shell 8, which is sleeved at the connection between the second shell 6 and the third shell 7, and is integrated with the second shell 6 and the third shell 7 to completely wrap the first shell 3.

[0095] The third shell 7 and the fourth shell 8 are snap connected, and the connection has a gap, and part of the impurities will enter the inside of the lock from the gap, so the fourth shell 8 is used to cover the connection between the second shell 6 and the third shell 7, eliminating the connection gap, as shown, providing complete sealing and protection for the lock, preventing foreign matter from entering from the connection; Figure 1

[0096] When installing, the fourth shell 8 is sleeved on the first shell 3, and then the second shell 6 and the third shell 7 are inserted from both ends of the fourth shell 8 to form an integrated whole, completely wrapping the first shell 3, ensuring the all-around protection of the internal components.
