[0013] Preferably, a tension spring is fixedly mounted on the bottom of the limiting plate, and the other end of the tension spring is fixedly connected to the inside of the fixed bottom plate.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. In the utility model, the gap between the door and the door frame is filled by the first filling block and the second filling block through the door gap filling device, so as to play a role in reinforcing the door body. The door gap filling device is directly connected to the door lock body. When the door lock body is closed, the first filling block and the second filling block will be inserted into the gap, and the second filling block will be supported by the connecting spring and pressed against the door frame and the door body, so as to minimize the misalignment of the door and the door frame, and the internal accommodating cavity also provides sufficient space for the movement of the second filling block, so as to adapt to some smaller gaps.

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0027] Embodiment 1

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a door lock device for transportation equipment, including a door lock body 1, one side of the door lock body 1 is fixedly connected with a door gap filling device 3, one end of the door lock body 1 is movably connected with a limiting device 2, the door gap filling device 3 includes a first filling block 31 and a second filling block 32, one end of the first filling block 31 is fixedly connected to one side of the door lock body 1, the second filling block 32 is movably installed on both sides of the first filling block 31, and a receiving cavity 33 is provided at the junction of the first filling block 31 and the second filling block 32, one side of the second filling block 32 is movably connected to the inside of the first filling block 31, one side of the second filling block 32 is fixedly installed with a plurality of positioning protrusions 34, the positioning protrusions 34 between the two second filling blocks 32 are staggered, one side of the two second filling blocks 32 is fixedly installed with a connecting spring 35, and the other end of each connecting spring 35 is fixedly connected to one side of the second filling block 32 on the other side.

[0029] The following is a detailed description of the specific settings and functions of this embodiment. One end of the door lock body 1 is connected to the door body, and the limiting device 2 is installed on the door frame. When in use, one end of the door lock body 1 is buckled onto the limiting device 2 to complete the locking of the door lock body 1. At this time, the door gap filling device 3 will be inserted into the gap between the door frame and the door body, and the second filling block 32 will move into the accommodating cavity 33 under the obstruction of the door frame and the door body. During the movement, the staggered positioning protrusions 34 will determine the moving direction and moving range of the two second filling blocks 32. During the movement of the second filling block 32, the connecting spring 35 will also be synchronously compressed to ensure that the second filling block 32 can enter the accommodating cavity 33. Later, when the door gap filling device 3 leaves the door gap, the reset of the connecting spring 35 will bounce the second filling block 32 back to its original position.

[0030] Embodiment 2

[0031] like Figure 1 and Figure 4 As shown, the limiting device 2 includes a fixed base plate 21 and a limiting plate 22. The bottom of the limiting plate 22 is slidably connected to the upper surface of the fixed base plate 21. A limiting groove 23 is provided inside the fixed base plate 21. An anti-slip plate 24 is fixedly installed at the bottom of the limiting plate 22. The anti-slip plate 24 is slidably connected to the inside of the limiting groove 23. The shape of the anti-slip plate 24 is adapted to the shape of the limiting groove 23. A tension spring 25 is fixedly installed at the bottom of the limiting plate 22. The other end of the tension spring 25 is fixedly connected to the inside of the fixed base plate 21.

[0032] The effect achieved by the entire embodiment is that the fixed base plate 21 is installed on the door frame. When in use, the limiting plate 22 is first pulled to move to one end of the fixed base plate 21, and then one end of the door lock body 1 is buckled onto the limiting plate 22. The limiting plate 22 is used to lock one end of the door lock body 1. At this time, the elastic force of the tension spring 25 will also pull the limiting plate 22, so that the connection between the limiting plate 22 and the door lock body 1 is more tightly, and in the process of moving the limiting plate 22, the limiting slide groove 23 will limit the moving route of the limiting plate 22 and prevent the limiting plate 22 from falling off from the fixed base plate 21.

[0033] How to use and working principle of this device:

[0034] When in use, first pull the limiting plate 22 to move to one end of the fixed bottom plate 21, then buckle one end of the door lock body 1 onto the limiting plate 22, and use the limiting plate 22 to lock one end of the door lock body 1;

[0035] At this time, the door gap filling device 3 will be inserted into the gap between the door frame and the door body, wherein the second filling block 32 will move into the accommodating cavity 33 and compress the connecting spring 35 synchronously under the obstruction of the door frame and the door body, and at the same time, the staggered positioning protrusions 34 will determine the moving direction and moving range of the two second filling blocks 32. After the second filling block 32 enters the accommodating cavity 33, it presses against the door frame and the door body, so as to minimize the misalignment between the door and the door frame;

[0036] When the door gap filling device 3 leaves the door gap, the reset of the connecting spring 35 will bounce the second filling block 32 back to its original position.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
