[0002] With the rapid development of society, the problem of emergency escape has attracted more attention. The unlocking device is particularly important as the last safety guarantee link. The appearance types of emergency valves in the prior art are various, especially among emergency valves with different principles. However, when a car encounters a car accident, the circuit is damaged or the air passage is blocked, the ordinary emergency valve cannot perform its function and cannot open the car door in time, thus unable to help the people in the car escape in time.
[0003] In order to solve the problems existing in the prior art, a safe escape device has become an urgent problem to be solved in the whole society. Content of the Utility Model
[0004] To solve the above technical problems, the technical solution provided by the utility model is: a safe escape device, including a lock seat body, a lock pin, a lock ring, a first spring, an unlocking wire rope and a bracelet. The lock ring is inserted into the hole of the lock seat body and locked by the lock pin. The unlocking wire rope is used to connect the tail end of the lock pin. The bracelet is connected to the tail of the unlocking wire rope. One end of the first spring is arranged outside the lock pin, and the other end is connected to the inner end of the lock seat body. A limiting component is arranged inside the lock seat body and is in contact connection with both sides of the front end of the lock pin. Two groups of second springs for popping up the lock ring are arranged inside the lock seat body. Pull the bracelet by hand, the bracelet drives the unlocking wire rope to move, so that the lock pin extrudes the first spring outwards. At this time, the lock ring breaks away from the restraint of the limiting component and separates from the lock pin, and the car door opens.
[0005] Further, the unlocking wire rope is a steel wire rope.
[0006] Further, two groups of screw holes are arranged on the lock seat body, and the lock seat body is installed on the side of the car door through screws in cooperation with the screw holes.
[0007] Advantages of the utility model compared with the prior art are as follows:
[0008] The utility model adopts the combination of multiple structures including a lock seat body, a lock pin, a lock ring, a spring, an unlocking wire rope and a bracelet. When the car encounters an emergency and needs to open the car door, only need to pull the bracelet by hand. The bracelet drives the unlocking wire rope to move, so that the lock pin extrudes the first spring outwards. At this time, the lock ring separates from the lock pin and the car door opens, which can solve the problem that the damage of the car circuit in the prior art affects the opening of the car door. The above structure can open the car door of the car in time and quickly, so as to facilitate the safe escape of the people in the car, and has strong practicability. Description of the Drawings

[0015] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0016] The present utility model will be introduced in detail with reference to the accompanying drawings.
[0017] When the present utility model is specifically implemented, a safety escape device is provided, including a lock seat body 1, a lock pin 2, a lock ring 3, a first spring 4, an unlock wire 5 and a bracelet 6. The lock ring 3 is inserted into the hole of the lock seat body 1 and locked by the lock pin 2. The unlock wire 5 is used to connect the tail end of the lock pin 2. The bracelet 6 is connected to the tail of the unlock wire 5. One end of the first spring 4 is arranged outside the lock pin 2, and the other end is connected to the inner end of the lock seat body 1. A limiting component 7 is arranged inside the lock seat body 1, and the limiting component 7 is in contact connection with both sides of the front end of the lock pin 2. Two groups of second springs 8 for bouncing the lock ring 3 are arranged inside the lock seat body 1. When pulling the bracelet 6 by hand, the bracelet 6 drives the unlock wire 5 to move, so that the lock pin 2 extrudes the first spring 4 outwards. At this time, the lock ring 3 breaks away from the restraint of the limiting component 7 and separates from the lock pin 2, and the car door opens. Embodiment
[0018] When the utility model is in use, since there are two sets of screw holes 7 provided on the lock seat body 1, the lock seat body 1 can be directly installed on the side of the car door by using screws. When the internal circuit of the car is damaged or the air circuit is blocked, the car door cannot be opened. The passengers inside the car can pull the bracelet 6 by hand. The bracelet 6 drives the unlocking wire 5 to move, so that the lock pin 2 extrudes the first spring 4 outwards. The lock pin 2 moves outwards. As the limit member 7, the locking steel balls start to move towards the middle during the process of the lock pin moving outwards. At this time, the lock ring 3 breaks free from the restraint of the locking steel balls and is ejected under the action of the second spring 8. At this time, the lock ring 3 is separated from the lock pin 2, and the car door opens, so that the passengers inside the car can achieve safe escape and avoid the occurrence of phenomena that affect the life and property safety of the passengers inside the car due to the inability to open the car door.
[0019] Among them, the end of the lock pin 2 is arranged in a conical structure. During the process of extruding the first spring 4, its conical tip stays in the longitudinal channel 9 to prevent the locking steel balls from detaching from the lock pin. Embodiment
[0020] A seat belt cutting device is arranged between the unlocking wire 5 and the bracelet 6, and the seat belt cutting device is a cutting blade. One end of the seat belt cutting device is used to connect the steel wire rope, and the other end is used to connect the bracelet. The middle part is equipped with a blade for cutting the seat belt. Through the above structure, the seat belt can be cut, and the practicability is relatively strong.
[0021] The unlocking wire 5 is a steel wire rope. The structural setting of the steel wire rope can increase the firmness of the whole device during use.
[0022] As a further elaboration of the utility model, there are two sets of screw holes 12 provided on the lock seat body 1, and the lock seat body 1 is installed on the side of the car door by matching the screws with the screw holes 7.
[0023] As a further elaboration of the utility model, a longitudinal channel 9 and a transverse channel 10 are arranged inside the lock seat body 1. The longitudinal channel 9 is communicated with the transverse channel 10. The limit member 7 is two sets of locking steel balls. One set of locking steel balls is arranged at the upper end of the lock pin 2, and one set of locking steel balls is arranged at the lower end of the lock pin 2.
[0024] As a further elaboration of the utility model, the unlocking wire 5 extends out from the longitudinal channel 9 on the side of the lock seat body 1.
[0025] As a further elaboration of the utility model, limiting groove bodies for cooperating with the locking steel balls are arranged on both the inner side of the top end and the inner side of the bottom end of the lock ring 3.
[0026] As a further elaboration of the utility model, two sets of cooperating holes 11 are arranged on the lock seat body 1 for cooperating and connecting with the lock ring 3, and the second spring 8 is installed at the inner end of the holes 11.
[0027] The above description is made on the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the gist of the creation of the present utility model, they design without creative efforts structural modes and embodiments similar to the technical solution, all of which shall fall within the protection scope of the present utility model.
