[0032] like Figures 1 to 5 As shown, this embodiment proposes a door lock device for a cargo box door, including a door lock body 1, a lock tongue 2, and a button assembly 3. The door lock body 1 is arranged on the side wall of the cargo box door 6, and the lock tongue 2 is rotatably mounted on the door lock body 1. The lock tongue 2 can cooperate with the lock pin on the cargo box door 6 to lock the cargo box door 6. The button assembly 3 is arranged on the side wall of the cargo box door 6 and abuts against the lock tongue 2. The button assembly 3 can be used to push the lock tongue 2 to rotate so that the lock tongue 2 is separated from the lock pin to achieve unlocking. In this application, by arranging the door lock body 1 on the side wall of the cargo box door 6, the position where the door lock body 1 is arranged is relatively hidden, avoiding the existing door lock being arranged at a conspicuous position of the cargo box door to affect the appearance of the cargo box door, and greatly improving the aesthetics of the cargo box door 6; by arranging the button assembly 3, the lock tongue 2 is pushed to rotate only by pressing the button assembly 3, so that the lock tongue 2 is separated from the lock pin to achieve unlocking, eliminating the pull rod required for unlocking, reducing costs, and making the operation simple and convenient.
[0033] For further information, see Figure 2 As shown, the button assembly 3 includes a button 31, and a through hole is provided on the side wall of the cargo box door 6, through which one end of the button 31 can pass and abut against the lock tongue 2, and the outer diameter of the end of the button 31 close to the lock tongue 2 gradually increases in the direction away from the lock tongue 2. In this way, by pressing the button 31, since the outer diameter of the end of the button 31 close to the lock tongue 2 gradually increases in the direction of the lock tongue 2, that is, it is arranged in a conical shape, as the button 31 moves toward the lock tongue 2, one end of the button continues to push the lock tongue 2, so that the lock tongue 2 rotates, and then separates from the lock pin, to achieve unlocking.
[0034] Furthermore, the button assembly 3 further comprises a compression spring (not shown in the drawings), which is sleeved on the button 31. By providing the compression spring, the button 1 can be pushed to move by the elasticity of the compression spring, so that the button 31 can be quickly reset.
[0035] For further information, see Figure 4 As shown, the button assembly 3 further includes a bushing 32, which can be used to install the button 31 in the through hole, one end of the compression spring abuts against the button 31, and the other end of the compression spring abuts against the bushing 32. By providing the bushing 32, on the one hand, the button 31 can be guided to move in a specified direction, and on the other hand, the compression spring can be limited and fixed in position with the button 31.
[0036] Preferably, see Figure 2 As shown, the button assembly 3 also includes a retaining ring 33. By setting the retaining ring 33, the button 31 can be seamlessly connected to the side wall of the cargo door 6, thereby preventing external foreign objects from being stuck between the button 31 and the side wall of the cargo door 6 and affecting the movement of the button 31.
[0037] For further information, see Figure 2 As shown, the door lock device further includes a bolt 4. A through hole is formed on the door lock body 1, and a threaded hole is formed on the side wall of the cargo box door 6. The bolt 4 passes through the through hole and is connected with the threaded hole. In this way, the door lock body 1 can be fixed to the side wall of the cargo box door 6 through the connection between the bolt and the threaded hole.
[0038] Preferably, see Figure 5 As shown, the lock tongue 2 is provided with an opening 21, and the lock pin is inserted into the opening 21 to achieve the connection between the lock tongue 2 and the lock pin, thereby locking the cargo box door 6. Preferably, the opening 21 is U-shaped. By being U-shaped, the lock pin can slide into or out of the opening 21 to achieve locking and unlocking of the cargo box door 6.
[0039] Preferably, see Figure 2 As shown, an avoidance notch 11 is provided on the side wall of the cargo door 6. By providing the avoidance notch 11, when the lock tongue 2 rotates, an avoidance space can be provided for the lock tongue 2, thereby preventing the lock tongue 2 from interfering with the side wall of the cargo door 6 when rotating. At the same time, the overall structure of the door lock device is more compact and occupies less space.
[0040] For further information, see Figure 2As shown, a baffle 5 is provided on the side wall of the cargo box door 6, and the avoidance notch 11 is provided on the baffle 5. By providing the baffle 5, the door lock device can be effectively protected. Preferably, the number of the baffles 5 is two, and the two baffles 5 and the side wall of the cargo box door 6 enclose a receiving space, and the door lock device is placed in the receiving space. By placing the door lock device in the receiving space, the door lock device is further protected to prevent the door lock device from being damaged by external force impact, thereby increasing the service life of the door lock device.
[0041] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
