Description

TECHNICAL FIELD

[0001] The utility model relates to an emergency device, concretely, especially relates to an emergency quick release device. BACKGROUND

[0002] In disease prevention and control work, the rapid and safe access of emergency supplies is crucial for effectively responding to public health emergencies. Xinjiang Uygur Autonomous Region has a vast territory and diverse geographical environments, and disease prevention and control work faces many special challenges. However, the existing emergency device storage equipment has many shortcomings and cannot meet the actual needs.

[0003] On the one hand, traditional emergency device storage boxes mostly use single-door or complex opening and closing structures. Single-door is limited in opening space when facing large emergency equipment, making it inconvenient and slow to open, which may delay the best opportunity for emergency disposal. Complex opening and closing structures, such as multiple locks and multiple levels of opening methods, are cumbersome to operate. In an emergency, staff may need to spend a lot of time unlocking and opening the door, affecting emergency response efficiency. Moreover, these doors often lack buffering measures when closing, and the impact force generated when closing may cause the door to deform and loosen, reducing the sealing of the box and potentially damaging the internal emergency devices, shortening the service life of the equipment.

[0004] On the other hand, the positioning and movement of the inner box are problematic. In existing storage equipment, the cooperation between the inner box and the outer box is not reasonable. When the inner box enters or exits the outer box, it often experiences jamming, height difference, and other phenomena. Jamming increases the difficulty of operation and prolongs the access time. The height difference not only makes the operation of pushing and pulling the inner box laborious, but also may cause the inner box to slide rapidly when pulled out, damaging the emergency supplies inside the inner box and posing a threat to the safety of the operator. In addition, the inner box is unstable during movement and difficult to accurately position, affecting subsequent fixing and access operations.

[0005] On the other hand, accurate positioning and reliable fixation of the inner box are crucial when storing emergency devices, but existing positioning methods are often not stable. When the equipment is subjected to vibration or external impact, the inner box may shift, making it difficult to access the emergency device normally. In emergency situations, the existing release mechanism has defects and cannot achieve quick and smooth release of the inner box, making it difficult to meet the strict requirements of time in emergency rescue. Moreover, when the door is damaged or not fully closed, there is a lack of effective measures to prevent the inner box from accidentally sliding out, which may damage the items inside the inner box or even harm surrounding personnel. Especially in disease control and prevention work sites, where personnel are dense and the environment is complex, the risk is even greater.

[0006] Therefore, those skilled in the art are committed to providing an emergency quick release device that can effectively solve the above technical problems. Utility model content

[0073] The optimal working principle of the utility model is as follows:

[0074] The box door 2 is opened and closed:

[0075] After the motor is started, the output end drives the driving assembly 10 to rotate, the driving assembly 10 is provided with two output ends and is hingedly connected with the upper half of the two sides of the inner wall of the box door 2, the driving assembly 10 is composed of two driving rods 12, the output end of the driving rod 12 is hingedly connected with a connecting piece 13, and the connecting piece 13 is fixed on the upper half of the two sides of the inner wall of the box door 2 through screws 15;

[0076] The input end of the driving rod 12 is rotatably sleeved on a rotating rod 16, the rotating rod 16 is installed on a swing rod 17, and the swing rod 17 is sleeved on a rotating shaft 18; the rotating shaft 18 is rotationally connected with the outer box body 1 and is connected with the output end of the motor;

[0077] When the motor drives the rotating shaft 18 to rotate, the swing rod 17 swings towards the direction of the box door 2, and then pushes the box door 2 to rotate around the rotating connection point of the outer box body 1 through the driving rod 12, so as to realize the simultaneous opening and closing of the two box doors 2; this design is particularly suitable for larger size box bodies, and compared with single door, not only occupies less space when opening, but also significantly speeds up the opening and closing speed of the box door 2;

[0078] The grid plate 19 in the upper half of the outer box body 1 supports and protects the driving mechanism 3, and the buffer layer at the front end of the grid plate 19 can buffer the impact force generated when the box door 2 is closed. When it is necessary to close the box door 2, the motor drives the rotating shaft 18 to rotate reversely, and the driving rod 12 pulls the box door 2 back, so as to complete the closing action of the box door;

[0079] Positioning and movement of the inner box body 5:

[0080] The pulleys 6 at the four corners of the bottom of the inner box body 5 cooperate with the pulley guide openings 27 at the bottom of the outer box body 1, so that the inner box body 5 can smoothly enter the outer box body 1; after entering the inner box body 1, there is no height difference, which not only makes the operation more labor-saving, but also makes it more convenient to pull out or push in the inner box body 5. At the same time, it also avoids the problem that when the inner box body 5 is pushed out, the height difference causes the inner box body 5 to slide out too fast, which makes it difficult for the operator to control. In addition, this design can also ensure that the positioning column 7 accurately passes through the guide opening 29;

[0081] The sliding grooves 23 on both sides of the inner box body 5 cooperate with the sliding rails 26 on the inner wall of the outer box body 1, further ensuring the stability of the inner box body 5 during movement;

[0082] The inner box body 5 is connected to the positioning column 7 at the rear end, and the limiting groove 8 at the rear half of the positioning column 7 extends out of the guide opening 29 at the rear end of the outer box body 1. When the limiting ring 30 contacts the outer box body 1, the inner box body 5 is limited and cannot be continuously pushed in, and at this time the limiting groove 8 corresponds to the locking hook 52. At this time, the locking hook 52 is opened outward (as shown in Figure 17 Fig. 5), and the locking rod 33 is pulled upward by the driving cylinder, so that the locking rod 33 drives the locking piece 39 to move upward. With the upward movement of the locking piece 39, the locking hook 52 approaches the guide cylinder 50, so that the locking hook 52 cooperates with the limiting groove 8 to fix the inner box body 5;

[0083] Emergency release

[0084] In the emergency, the driving cylinder reverses, pushing the locking rod 33 downward. The locking piece 39 moves downward, and when the arc segment 39a of the locking piece 39 contacts the guide cylinder 50, the locking hook 52 separates from the positioning column 7, and the locking hook 52 is separated from the limiting groove 8 of the positioning column 7, so that the positioning column 7 is no longer limited. By opening the box door, the inner box body 5 can be pulled out, and the inner box body 5 is quickly slid out of the outer box body 1 through the pulley guide opening 27 by means of the pulley 6, so that the emergency device is quickly released.

[0085] The above design not only enhances the stability of the inner box body 5 in the outer box body 1, but also effectively avoids the situation that the inner box body 5 slides outwards when the box door is damaged or not closed tightly. The outer sliding of the inner box body 5 not only may damage the articles in the inner box body, but also may collide with pedestrians to cause injury, especially in a crowded place or on a slope, which is more dangerous.

[0086] The protective cover 53 at the rear end of the outer box body 1 can protect the positioning plate 31, the positioning disc 37 and the locking piece 39 and other components, so that they are not interfered and damaged by the outside.

[0087] The above describes the preferred embodiments of the present application in detail. It should be understood that those skilled in the art can make many modifications and changes without creative labor according to the concept of the present application. Therefore, any technical solution obtained by logical analysis, reasoning or limited experiment on the basis of the prior art according to the concept of the present application shall be within the protection scope defined by the claims.
