Description

Technical Field

[0001] The invention relates to a medical device, in particular to a cover plate structure of an aviation airborne nursing cart, specifically to a cover plate positioning and fixing mechanism of an airborne nursing cart. Background Art

[0002] At present, nursing carts are all equipped with covers to ensure the safety of medicines and equipment during walking, and the covers need to be opened when arriving at the nursing position. Most of the existing covers adopt a flip-up or manually removable structure. This structure is completely fine under normal circumstances, but in the case of airborne, the flip-up type will occupy the space structure, and the manual take-and-place type will affect safety, both of which are not desirable. Therefore, it is urgent to design a cover deployment and collection mechanism that can cover the container and automatically retract into the vehicle body when in use. The most critical thing is that the cover needs to be locked on the vehicle body when not stored, so a corresponding handle structure must be designed to achieve this purpose. Summary of the invention

[0003] The purpose of the present invention is to design a positioning and fixing mechanism for the cover plate of an onboard nursing cart in view of the problem that the cover plate of an existing onboard nursing cart needs to be positioned when in use.

[0004] The technical solution of the present invention is:

[0005] A positioning and fixing mechanism for an onboard nursing cart cover, comprising a handle upper cover 1 and a handle lower cover 2, wherein the handle lower cover 2 is pivotally mounted with a handle lock tongue 3 and an unlocking handle 4, the tongue of the handle lock tongue 3 is inserted into a socket on the vehicle body when the handle lower cover 2 is extended out, and a handle compression spring 5 is installed between the handle lock tongue 3 and the unlocking handle 4 so that the lock tongue of the handle lock tongue 3 is always subjected to an outward pushing force.

[0006] The handle lock tongue 3 is of a Z-shaped structure, with its mounting pivot located in the middle position. The lock tongue at one end extends out of the handle lower cover 2 under the action of the handle compression spring 5, and the bent protrusion at the other end abuts against one end of the unlocking handle 4. The other end of the unlocking handle 4 is pivotally mounted on the pivot in the handle lower cover 2, and one end of the handle compression spring 5 abuts against the pivot end of the unlocking handle 4.

[0007] Beneficial effects of the present invention:

[0008] The invention solves the problem of locking and unlocking the cover plate of the onboard nursing vehicle and realizes reliable locking of the cover plate.

[0009] The invention has the advantages of simple structure, compact structure, small volume and reliable action. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1-7 shown.

[0019] A cover plate positioning and fixing mechanism for an onboard nursing cart, comprising an upper handle cover 1 and a lower handle cover 2 (such as Figure 3 As shown), its installation position on the cover plate 6 of the onboard nursing cart is as shown Figure 1 , 2 As shown, the handle upper cover 1 is substantially flush with the surface of the cover plate 6, the insert handle lower cover 2 is connected to the handle upper cover 1, and its main body is located at the lower part of the cart cover plate 6 (as shown in FIG. Figure 2 As shown). The handle lower cover 2 is pivotally mounted with a handle lock tongue 3 and an unlocking handle 4, as shown in FIG. Figure 4 As shown, the tongue of the handle lock tongue 3 is inserted into the insertion hole on the vehicle body when the handle lower cover 2 is extended outward to realize the locking of the cover plate, and a handle compression spring 5 is installed between the handle lock tongue 3 and the unlocking handle 4 so that the lock tongue of the handle lock tongue 3 is always subjected to an outward pushing force. The handle lock tongue 3 is in a Z-shaped structure, and its mounting pivot is located in the middle position. The lock tongue at one end extends outward from the handle lower cover 2 under the action of the handle compression spring 5, and the bent protrusion at the other end abuts against one end of the unlocking handle 4. The other end of the unlocking handle 4 is pivotally mounted on the pivot in the handle lower cover 2, and one end of the handle compression spring 5 abuts against the pivot end of the unlocking handle 4.

[0020] The locking state structure of the cover positioning and fixing mechanism of the onboard nursing cart of the present invention is as follows: Figure 3-6 As shown, the unlocked state is Figure 7 shown.

[0021] The cover handle of the present invention is mainly composed of a handle upper cover 1, a handle lower cover 2, a handle lock tongue, an unlocking handle 4, a handle compression spring 5 and other components. The handle is in a free state and is locked under the action of the handle compression spring; the entire handle is clamped and installed on the cart cover 6 by the handle upper cover and the handle lower cover. When the cover is to be unlocked, just pull the unlocking handle, the unlocking handle swings a certain angle, drives the handle lock tongue to swing into the handle, the handle is unlocked, and the handle cover is lifted, and the entire cover can be lifted and rotated.

[0022] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art.
