Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a spring-rolled anti-opening first aid trolley. Background Art

[0002] In order to place first aid supplies such as first aid drugs and oxygen inhalation devices at multiple points inside a hospital, existing hospitals usually adopt movable first aid trolleys. The trolleys classify and store first aid supplies through a cabinet body, cabinet doors and drawers. Usually, in order to prevent first aid supplies from being taken away by unauthorized persons under non-emergency conditions, a lock tongue and a lock catch are provided on each cabinet door, and the cabinet door is locked with a disposable padlock. In case of an emergency, the disposable padlock can be broken to open the cabinet door. However, this method requires a lot of disposable padlocks, resulting in the waste of first aid time due to the need to break many disposable padlocks in case of an emergency. Therefore, on the market, there appears a baffle made of stainless steel that abuts against the cabinet door to prevent the cabinet door from being opened, and then 1-2 disposable padlocks are used to lock the stainless steel baffle. In an emergency, only a small number of disposable padlocks need to be broken, and then the stainless steel baffle can be removed to open the cabinet door. However, this kind of stainless steel baffle is usually relatively heavy, and it is laborious and time-consuming to install and remove, which is not convenient for nurses to use.

[0021] The present utility model provides a spiral spring type anti-opening first aid trolley, as Figure 1-5As shown in the figure, it includes a cabinet body 1, a roll box 2, a coil spring 3, a guide rail 4, a traction head 5, a lock tongue 6, a lock handle 7 and a disposable padlock 8; the cabinet body 1 is symmetrically provided with a cabinet door 11 and a drawer 12; the guide rail 4 is arranged on the axis of symmetry of the cabinet door 11 and the drawer 12, and the top of the guide rail 4 is bent towards the top of the cabinet body 1; the roll box 2 is arranged at the bottom of the cabinet body 1, one end of the coil spring 3 is wound in the roll box 2, and the other end is fixedly installed on the traction head 5, the traction head 5 is limitedly installed in the guide rail 4 and can only move along the guide rail 4; the width of the coil spring 3 is greater than the interval distance between two adjacent cabinet doors 11 or two drawers 12; the lock handle 7 is hingedly installed on the traction head 5, the lock tongue 6 is fixedly installed on the top of the cabinet body 1 and is located at the end of the guide rail 4, a lock hole 61 is opened on the lock tongue 6, and a through groove 71 is opened on the lock handle 7; in the locked state of the door, the traction head 5 moves to the top end of the guide rail 4, and at the same time the coil spring 3 is drawn out from the roll box 2 and covers the side of the guide rail 4, so as to also cover the side of the cabinet door 11 and the drawer 12. At this time, the lock handle 7 is hooked onto the lock tongue 6, so that the lock tongue 6 passes through the through groove 71. At this time, the disposable padlock 8 is fixedly passed through the lock hole 61 and self-locks into a lock ring, so that the lock handle 7 is limited in the lock tongue 6. At this time, the coil spring 3 is located beside the cabinet door 11 and the drawer 12 and hinders the opening of the cabinet door 11 and the drawer 12, thereby preventing idlers from opening the cabinet door 11 and the drawer 12 to take emergency items in non-emergency situations; in case of an emergency, by destroying the disposable padlock 8, the lock handle 7 is released from the limit and separated from the lock tongue 6, and at this time it enters the unlocked state; in the unlocked state, the coil spring 3 uses its own elastic potential energy to retract back into the roll box 2, and the traction head 5 is pulled to the bottom of the guide rail 4 by the coil spring 3. At this time, the cabinet door 11 and the drawer 12 are not hindered and can be normally opened, so as to take emergency items.

[0022] Preferably, the inside of the guide rail 4 is a T-shaped groove.

[0023] Preferably, the traction head 5 is provided with a limit post 51 corresponding to the T-shaped groove, so that the limit post 51 is always located in the T-shaped groove; the traction head 5 further includes a vertical plate 52, the vertical plate 52 is fixedly connected to the limit post 51, and one end extends outward from the T-shaped groove and is fixedly installed with the coil spring 3. By pulling the traction head 5 to move along the guide rail 4, the coil spring 3 will be pulled out or retracted.

[0024] Preferably, a pull ring 53 is further fixedly installed beside the vertical plate 52, which is convenient for the user to pass a finger through the pull ring 53, so as to facilitate pulling the traction head 5.

[0025] Preferably, a guide wheel 13 corresponding to the position of the guide rail 4 is provided at the bottom of the cabinet body 1 for steering the coil spring 3 to reduce the friction between the coil spring 3 and the cabinet body 1.

[0026] Preferably, universal wheels 9 are further provided at the bottom of the cabinet body 1, so as to facilitate the flexible pushing of the cabinet body 1 for movement.

[0027] The technical effect of the present utility model is mainly reflected in that: by pulling the towing head to move to the top end of the guide rail, hooking the lock handle onto the lock tongue, enabling the lock tongue to pass through the through slot, and then fixedly passing a disposable padlock through the lock hole and self-locking it into a lock ring. At this time, the coil spring is located beside the cabinet door and the drawer and hinders the opening of the cabinet door and the drawer, thereby preventing emergency items from being randomly taken and used, reducing the number of too many locks on the cabinet door. Moreover, after the lock tongue and the lock handle are unlocked, the coil spring automatically retracts back into the coil box, which is conducive to quickly unlocking in an emergency situation and shortening the time for taking emergency items.

[0028] Of course, the above are only typical examples of the present utility model. In addition, the present utility model can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present utility model.
