DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 4The utility model provides a technical solution: a locking mechanism of a protection cabin, which includes a protection cabin 1, a positioning plate 2, a cabin door 3, a protective strip 4, a handle 5, an electric control box 6, an unlocking device 7, an electric push rod 8, a transmission rod 9, a release block 10, a movable groove 11, a first spring 12, a locking block 13, a lock buckle 14, an end plate 15, a conical surface 16 and a second spring 17. A positioning plate 2 is provided at the front end of the protection cabin 1, a cabin door 3 is provided on the left side of the positioning plate 2, two protective strips 4 are provided at the upper and lower ends of the cabin door 3 and the positioning plate 2, and a handle 5 is provided at the front end of the cabin door 3. The positioning plate 2 and the cabin door 3 cooperate to form a closed structure of the protection cabin, wherein the protective strip 4 increases the sealing and safety of the cabin door, and the user can open or close the cabin door under normal circumstances by operating the handle 5.

[0025] An electric control box 6 is provided at the left end of the protection cabin 1, an unlocking device 7 is provided at the front end of the electric control box 6, an electric push rod 8 is provided inside the electric control box 6, a transmission rod 9 is provided at the right end of the electric push rod 8, a release block 10 is provided at the right end of the transmission rod 9, a movable groove 11 is provided in the middle of the right end of the release block 10, and two first springs 12 are provided at the right end of the release block 10. After receiving the unlocking command, the electric control box 6 is activated and then drives the electric push rod 8 to work. The electric push rod 8 pushes the transmission rod 9 through its action. As the transmission rod 9 pushes, the release block 10 starts to move to the right. This action is The electric push rod 8 directly acts on the release block 10. As the release block 10 moves to the right, the lock buckle 14 begins to move inward into the movable groove 11. Since the lock buckle 14 has a conical surface 16, this design makes the lock buckle 14 receive inward pressure when it contacts the two protrusions in front of the release block 10. This pressure causes the two lock buckles 14 to move closer to each other, that is, the distance between the two lock buckles 14 is reduced. When the distance between the two lock buckles 14 is reduced to a size that is large enough to pass through the hole between the two locking blocks 13 on both sides of the protective cabin, the lock buckle 14 can be pushed through the hole.

[0026] Two locking blocks 13 are provided at the right end of the protective cabin 1, and two lock buckles 14 are provided at the left end of the cabin door 3. An end plate 15 is provided at the right end of the lock buckle 14, and a conical surface 16 is provided at the left end of the lock buckle 14. A second spring 17 is provided inside the lock buckle 14. The lock buckle 14 passes through the hole between the two locking blocks 13. During the entire unlocking process, the inward movement of the lock buckle 14 and the ability to pass through the hole between the locking blocks 13 depend on the design of the conical surface 16 on the lock buckle 14. This design cleverly utilizes the change in the direction of the mechanical force, so that the lock buckle 14 can automatically compress inward under the action of external force to complete the unlocking action. This mechanism ensures that the locking mechanism of the protective cabin can be quickly unlocked when needed.

[0027] Working principle: The positioning plate 2 and the hatch 3 cooperate to form a closed structure of the protective cabin, in which the protective strip 4 increases the sealing and safety of the hatch. The user can open or close the hatch under normal circumstances by operating the handle 5. The electric control box 6 is activated after receiving the unlocking command, and then drives the electric push rod 8 to work. The electric push rod 8 pushes the transmission rod 9 through its action. With the push of the transmission rod 9, the release block 10 starts to move to the right. This action is achieved by the electric push rod 8 directly acting on the release block 10. With the rightward movement of the release block 10, the lock buckle 14 starts to move inward into the movable groove 11. Since the lock buckle 14 has a conical surface 16, this design makes the lock buckle 14 receive inward pressure when it contacts the two protrusions in front of the release block 10. This pressure prompts the two lock buckles 14 to move When the distance between the two lock buckles 14 is reduced to a size large enough to pass through the hole between the two locking blocks 13 on both sides of the protective cabin, the lock buckle 14 can be pushed through the hole. After the lock buckle 14 completely passes through the hole between the locking blocks 13, the locking mechanism is successfully unlocked and the hatch 3 can be opened. During the entire unlocking process, the inward movement of the lock buckle 14 and the ability to pass through the hole between the locking blocks 13 depend on the design of the conical surface 16 on the lock buckle 14. This design cleverly utilizes the change in the direction of the mechanical force so that the lock buckle 14 can automatically compress inward under the action of an external force to complete the unlocking action. This mechanism ensures that the locking mechanism of the protective cabin can be quickly unlocked when needed and maintain a high degree of security in the locked state.
