[0015] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:
[0016] First, the utility model is provided with a disassembly mechanism, and when it is necessary to open the left and right door, the second pull block is grasped and pulled outward, and at this time the second pull block drives the sliding plate to move outward synchronously, and the second hard spring is deformed due to the pulling force generated when the sliding plate moves, and at this time the sliding plate drives the plug block to move out of the inner cavity of the plug hole, releasing the limit on the fixed plate, and then the first pull block is grasped and pulled to the left side to move it into the inner cavity of the box body, and the first hard spring is deformed due to the extrusion force generated when the fixed plate moves, and the mutual limit between the left and right doors is released through the movement of the fixed plate, thereby facilitating the opening of the left and right doors, and when it is necessary to close the left and right doors, When the first pull block is released, the first hard spring loses its force and deforms again, and pushes the fixed plate to the right by its own tension, and the fixed plate enters the inner side of the box body. Then the second pull block is released, and the second hard spring loses its force and deforms again, and drives the sliding plate to move inward by its own pulling force. The plug block is again plugged into the inner cavity of the socket due to the movement of the sliding plate, completing the limiting work of the left door and the right door. The way of opening and closing the left door and the right door is simple. Compared with using an external padlock, it can effectively avoid the situation where the left door and the right door cannot be opened when the key is lost, thereby improving the convenience of opening and closing the left door and the right door, and facilitating people's use.
[0017] Second, the utility model can limit the moving direction of the second pull block by providing a displacement groove, so as to avoid the second pull block from deviating when moving, causing the sliding plate to drive the moving direction of the plug block to change synchronously, thereby affecting the limiting of the fixed plate, making it impossible for the left and right door to open and close normally. By providing a slot, the movement of the plug block can be limited, so as to avoid the direction of deviation when moving, thereby failing to connect with the fixed plate, resulting in the problem that the fixed plate cannot limit the left and right doors. By providing a box body and a sliding plate, since the size of the sliding plate matches the size of the inner cavity of the box body, the sliding plate will not flip up and down when moving, effectively avoiding the problem that the plug block cannot be plugged into the inner cavity of the socket due to the deviation when the sliding plate moves. By providing a through hole, the fixed plate can be The moving direction of the fixed plate is limited to avoid deviation during movement, which may cause the plug block to be unable to be inserted into the inner cavity of the socket. By setting the moving groove, the moving direction of the first pull block can be limited to avoid the synchronous deviation of the moving direction of the fixed plate due to direction deviation when the first pull block is pulled to move, thereby affecting the limiting work of the left and right doors. By setting the fixed plate and the box body, the sizes of the fixed plate and the inner side of the box body match each other, so that when the fixed plate moves to the inner side of the box body, the plug block and the socket are at the same vertical angle, which is convenient for the movement of the plug block. By setting the pulling groove and the third pulling block, the opening and closing of the left and right doors inside the car can be facilitated, avoiding the problem that the operator is accidentally locked into the car when he is inside the car, which makes it impossible for the operator to get out of the car.

DETAILED DESCRIPTION
[0026] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.
[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0028] Example 1
[0029] like Figure 1-5 As shown, the embodiment of the utility model provides a car door lock, comprising a left door 1, a right door 3 is arranged on the right side of the left door 1, and both the left door 1 and the right door 3 are arranged on the outside of the car compartment through hinges;
[0030] The left door 1 and the right door 3 are provided with a disassembly mechanism 2 on both upper and lower sides of the front side. The disassembly mechanism 2 includes a box body 201, which is fixedly installed on the upper and lower sides of the front side of the left door 1. Slide rods 202 are fixedly installed on the upper and lower sides of the inner cavity of the two box bodies 201. The surfaces of the four slide rods 202 are slidably connected with fixed plates 203. The front sides of the two fixed plates 203 are fixedly installed with first pull blocks 205. The upper and lower sides of the two fixed plates 203 are provided with sockets 212. A first hard spring 204 is fixedly installed on the left side, a box body 206 is fixedly installed on the upper and lower sides of the front side of the right compartment door 3, a sliding rod 207 is fixedly installed in the inner cavity of the two boxes 206, and sliding plates 208 are slidably connected to the upper and lower sides of the surfaces of the two sliding rods 207, a second hard spring 209 is fixedly installed on the inner side of the four sliding plates 208, a second pull block 210 is fixedly installed on the front side of the four sliding plates 208, and an insert block 211 is fixedly installed on the inner side of the four sliding plates 208.
[0031] By setting the disassembly mechanism 2, when it is necessary to open the left door 1 and the right door 3, by grasping the second pull block 210 and pulling it outward, the second pull block 210 drives the sliding plate 208 to move outward synchronously, and the second hard spring 209 is deformed due to the pulling force generated when the sliding plate 208 moves. At this time, the sliding plate 208 drives the plug block 211 to move out of the inner cavity of the socket 212, releasing the limit on the fixed plate 203, and then grasping the first pull block 205 and pulling it to the left side to move it into the inner cavity of the box body 201. The first hard spring 204 is deformed due to the squeezing force generated when the fixed plate 203 moves. Through the movement of the fixed plate 203, the mutual limit between the left door 1 and the right door 3 is released, thereby facilitating the opening of the left door 1 and the right door 3. When the left door 1 and the right door 3 need to be closed, When the first pull block 205 is released, the first hard spring 204 loses its force and deforms again, and pushes the fixed plate 203 to the right by its own tension, and the fixed plate 203 enters the inner side of the box body 206, and then the second pull block 210 is released. The second hard spring 209 loses its force and deforms again, and drives the sliding plate 208 to move inward by its own pulling force. The plug block 211 is plugged into the inner cavity of the socket 212 again due to the movement of the sliding plate 208, completing the limiting work of the left door 1 and the right door 3. The way of opening and closing the left door 1 and the right door 3 is simple. Compared with using an external padlock, it can effectively avoid the situation where the left door 1 and the right door 3 cannot be opened when the key is lost, thereby improving the convenience of opening and closing the left door 1 and the right door 3, and facilitating people's use.
[0032] Example 2
[0033] In one embodiment, the front sides of the two boxes 206 are provided with displacement grooves 214, the four second pull blocks 210 are all penetrated through the inner cavities of the two displacement grooves 214 and extend to the front sides of the two boxes 206, the inner sides of the two boxes 206 are provided with slots 213, the plug blocks 211 are penetrated through the inner cavities of the slots 213 and inserted into the inner cavities of the plug holes 212, the width of the sliding plate 208 matches the width of the inner cavities of the boxes 206, and the sliding plate 208 is slidably connected to the inner cavities of the boxes 206, the right sides of the inner cavities of the two boxes 201 are provided with through holes 216, the fixing plate 203 is penetrated through the inner cavities of the through holes 216 and extends to the boxes 201 On the right side, movable grooves 215 are provided on the front sides of the two box bodies 201, and the two first pull blocks 205 pass through the inner cavities of the two movable grooves 215 and extend to the front side of the box body 201. The sizes of the two fixed plates 203 match the sizes of the inner sides of the two box bodies 206, and the two fixed plates 203 are snapped onto the inner sides of the two box bodies 206. Pull grooves 217 are provided on the upper and lower sides of the rear sides of the left door 1 and the right door 3, and the rear sides of the four sliding plates 208 and the rear sides of the fixed plates 203 are fixedly installed with third pull blocks 218, and the six third pull blocks 218 pass through the inner cavities of the four pull grooves 217 and extend to the rear sides of the left door 1 and the right door 3.
[0034] By setting the displacement groove 214, the moving direction of the second pull block 210 can be limited to avoid the second pull block 210 from deviating when moving, causing the sliding plate 208 to drive the moving direction of the plug block 211 to change synchronously, thereby affecting the limiting of the fixed plate 203, so that the left door 1 and the right door 3 cannot be opened and closed normally. By setting the slot 213, the movement of the plug block 211 can be limited to avoid the direction of deviation when moving, thereby failing to connect with the fixed plate 203, resulting in the problem that the fixed plate 203 cannot limit the left door 1 and the right door 3. By setting the box body 206 and the sliding plate 208, since the size of the sliding plate 208 matches the size of the inner cavity of the box body 206, the sliding plate 208 will not flip up and down when moving, effectively avoiding the problem that the plug block 211 cannot be plugged into the inner cavity of the plug hole 212 due to the deviation of the sliding plate 208 when moving. By setting the through hole 216, the fixed plate The moving direction of the first pull block 205 is limited to avoid deviation during movement, which may cause the plug block 211 to be unable to be plugged into the inner cavity of the plug hole 212. By setting the moving groove 215, the moving direction of the first pull block 205 can be limited to avoid the synchronous deviation of the moving direction of the fixed plate 203 due to the direction deviation when the first pull block 205 is pulled to move, thereby affecting the limiting work of the left door 1 and the right door 3. By setting the fixed plate 203 and the box body 206, The dimensions of the fixing plate 203 and the inner side of the box body 206 match each other, so that when the fixing plate 203 is moved to the inner side of the box body 206, the plug block 211 and the socket 212 are at the same vertical angle, which is convenient for the movement of the plug block 211. By providing the pull groove 217 and the third pull block 218, the left door 1 and the right door 3 can be easily opened and closed inside the car, avoiding the problem that the operator is accidentally locked into the car when he is inside the car, resulting in the operator being unable to get out of the car.
[0035] When the utility model is working: when it is necessary to open the left door 1 and the right door 3, first pull the second pull block 210 and move it outward. With the movement of the second pull block 210, the sliding plate 208 moves outward synchronously and drives the plug block 211 to move out of the inner cavity of the plug hole 212. At this time, due to the movement of the sliding plate 208, the second hard spring 209 is deformed due to the tension. Then, the first pull block 205 is grasped and pulled to the left. At this time, the first pull block 205 drives the fixed plate 203 to move synchronously to the left. The first hard spring 204 is deformed due to the squeezing of the first pull block 205. When the box body 206 moves out from the inner side of the box body 206, the left door 1 and the right door 3 can be opened by flipping over. When the left door 1 and the right door 3 need to be closed, the carriage can be opened. When the right compartment door 3 is opened, the left compartment door 1 and the right compartment door 3 are flipped over again, and then the first pull block 205 is released. At this time, the first hard spring 204 is deformed again due to the loss of force, and through its own tension, it pushes the fixed plate 203 to move to the right, so that it moves to the inner side of the box body 206, and then the second pull block 210 is released. At this time, the second hard spring 209 is deformed again due to the disappearance of the pulling force, and through its own pulling force, it pulls the sliding plate 208 to move inward. At this time, the plug block 211 moves inward synchronously with the sliding plate 208, and is inserted into the inner cavity of the socket 212 along the inner cavity of the slot 213. By limiting the fixed plate 203, the left compartment door 1 and the right compartment door 3 cannot be flipped to the front side, thereby realizing the closing of the compartment.
[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
