Abstract
Description
Technical Field
[0001] This utility model relates to the field of explosion-proof vehicle compartment lock technology, and in particular to an explosion-proof vehicle compartment lock assembly. Background Technology
[0002] Side panels are a major component of the side walls of freight vehicles, typically made of steel or aluminum alloy, offering high strength and corrosion resistance. Their structure comes in two types: flat and corrugated. The latter enhances rigidity and reduces weight. Some models feature a detachable design for easy loading, unloading, and maintenance. Side panels must meet industry safety standards to ensure they do not deform or crack during transport, and their surfaces are treated with rust prevention to extend their service life. On specialized vehicles, side panels may be equipped with reinforced chain hooks or cushioning devices to accommodate different cargo requirements.
[0003] In practice, to facilitate loading, unloading, and maintenance of goods, the side panels are designed to open or close as needed. Therefore, easy-to-remove fixing pins are installed between the side panels. Connecting or separating the side panels is achieved by inserting and removing these pins, thus meeting practical functional requirements. However, the existing fixing pin structure is relatively simple, and to facilitate manual insertion and removal, relatively large spaces are reserved on the side panels, resulting in a loose connection between them. Even so, manual operation remains inconvenient. Utility Model Content

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0018] An explosion-proof vehicle compartment lock assembly includes: a fixing pin 1, a connecting rod 2, and a push-pull structure 3. The connecting rod 2 is used to connect to a side plate. The fixing pin 1 is slidably connected to the connecting rod 2. The push-pull structure 3 is connected to the connecting rod 2. The push-pull structure 3 is drively connected to the fixing pin 1 to drive the fixing pin 1 to slide relative to the connecting rod 2.
[0019] In practical applications, the connecting rod 2 is fixed to one of the side plates with screws. Simultaneously, the movement path of the fixing pin 1 corresponds to the connecting post on the other side plate, allowing the fixing pin 1 to insert into or pull out of the connecting post during sliding, thus connecting or separating the two side plates. Therefore, the operator only needs to operate the push-pull structure 3 to slide the fixing pin 1. In summary, this greatly simplifies operation. Furthermore, the connecting rod 2 and the push-pull structure 3 effectively limit the sliding range of the fixing pin 1, eliminating the need for additional space in the side plates for it, resulting in a tighter connection between the two side plates during actual operation.
[0020] An offset rod 11 is provided on the fixing pin 1. The offset rod 11 is inclined relative to the fixing pin 1. One end of the offset rod 11 is fixedly connected to the fixing pin 1. The other end of the offset rod 11 is connected to the connecting rod 2.
[0021] The position of the fixing pin 1 is adjusted appropriately by the offset rod 11 so that the fixing pin 1 can meet the actual assembly environment.
[0022] The push-pull structure 3 includes an operating lever 31, a transmission rod 32, and a sliding rod 33. The sliding rod 33 is connected to the fixing pin 1. The sliding rod 33 is slidably connected to the connecting rod 2. One end of the operating lever 31 is rotatably connected to the sliding rod 33. One end of the transmission rod 32 is rotatably connected to the operating lever 31. The other end of the transmission rod 32 is rotatably connected to the connecting rod 2. The sliding rod 33 has a connecting groove 331, which corresponds to the connecting rod 2. The sliding rod 33 is fastened to the connecting rod 2 through the connecting groove 331. Simultaneously, the connecting rod 2 has a sliding groove 21, which passes through the connecting rod 2. The rotational shaft between the operating lever 31 and the sliding rod 33 is located within the sliding groove 21.
[0023] For ease of description, the rotation axis between the operating lever 31 and the sliding lever 33 is referred to as rotation axis A, and the rotation axis between the operating lever 31 and the transmission rod 32 is referred to as rotation axis B. When the operator presses the operating lever 31, causing it to move closer to the connecting rod 2, the operating lever 31 will rotate relative to the transmission rod 32 about the rotation axis B. Simultaneously, the operating lever 31 will drive the transmission rod 32, causing it to rotate relative to the connecting rod 2. Thus, under the aforementioned combined action, the rotation axis A will be pushed to slide along the groove 21 of the connecting rod 2, thereby causing the sliding lever 33 to slide along the connecting rod 2. In this way, the sliding lever 33 will drive the fixing pin 1 to slide along the connecting rod 2. Through the aforementioned process, the operator pushes out the fixing pin 1, completing the connection of the side plate. Conversely, the operator pulls the operating lever 31, causing it to move away from the connecting rod 2, thereby retracting the fixing pin 1 and separating the side plate. Thus, the push-pull structure 3 can effectively drive the fixing pin 1 to move. Meanwhile, through the cooperation of the connecting groove 331, the sliding groove 21 and other structures, the movement direction and range of the fixed pin 1 are effectively restricted.
[0024] The operating lever 31 is provided with a first receiving groove 311. The transmission rod 32 is provided with a second receiving groove 321. The first receiving groove 311 corresponds to the transmission rod 32 so that the operating lever 31 can be engaged with the transmission rod 32. The second receiving groove 321 corresponds to the connecting rod 2 so that the transmission rod 32 can be engaged with the connecting rod 2.
[0025] By cooperating with the first receiving groove 311 and the second receiving groove 321, the operating rod 31, transmission rod 32, and connecting rod 2 are engaged when the side plate is in the connected state, thus ensuring that all structures are approximately aligned on a straight line. This effectively reduces the space occupied by the device and makes the overall device more aesthetically pleasing.
[0026] The push-pull structure 3 also includes a limiting torsion spring 34. The limiting torsion spring 34 is sleeved on the rotating shaft between the operating rod 31 and the transmission rod 32. Extension rods 341 are fixedly provided at both ends of the limiting torsion spring 34. One extension rod 341 abuts against the operating rod 31. The other extension rod 341 abuts against the transmission rod 32.
[0027] When the locking pin 1 needs to retract, the operator pulls the operating lever 31, causing the entire device to bend as shown in the attached diagram. The operating lever 31 and the transmission lever 32 act on their respective abutting extension levers 341, creating an angle between the two extension levers 341. At this time, the limiting torsion spring 34 accumulates elastic force, which then acts on the operating lever 31 and the transmission lever 32 through the extension levers 341, causing the operating lever 31 and the transmission lever 32 to return to their engaged state. Therefore, based on the action of the limiting torsion spring 34, when the device is not affected by external force, the locking pin 1 extends by default, keeping the side plates connected. This improves the safety of the device.
