Description

Technical Field

[0001] The utility model belongs to the field of trolleys, and particularly relates to a medical gas cylinder trolley. Background Art

[0002] In clinical medicine, medical gas cylinders are essential medical devices in surgeries and first aids, and it is very troublesome to carry medical gas cylinders. When carrying, first, the heavy medical gas cylinder needs to be lifted onto the trolley, transported to the designated place by the trolley, and then carried down and placed properly.

[0003] To ensure the flexibility of the medical gas cylinder trolley during the carrying process, the number of rollers at the bottom is generally two or three. The number of rollers of common medical gas cylinder trolleys is generally two. Medical staff lift the medical gas cylinder onto the trolley and fix it, then turn the trolley backward so that the bottom of the trolley is a short distance away from the ground, and the medical gas cylinder can be pushed to the designated place. Although this can also achieve the purpose of carrying the medical gas cylinder, this medical gas cylinder trolley is not stable enough during the carrying process, and it is more laborious for medical staff during the carrying process. In addition, although some gas cylinder trolleys adopt a three-wheel design structure, during the carrying process, due to the lack of shock absorption function on the gas cylinder trolley, when the gas cylinder trolley shakes up and down, the medical gas cylinder is likely to collide with the frame. Summary of the Utility Model

[0004] In view of the above problems, the purpose of the utility model is to provide a medical gas cylinder trolley, aiming to solve the problem that the medical gas cylinder is easy to shake and the carrying process is not stable enough in the existing medical gas cylinder trolley.

[0005] The utility model adopts the following technical scheme:

[0006] The medical gas cylinder trolley includes a frame. A pair of rollers are rotatably arranged at the bottom of the frame. A gas cylinder bracket is arranged on the front of the frame, and a connecting frame is arranged on the back. A connecting seat is arranged on the connecting frame. A support arm and a linkage plate are respectively rotatably arranged on the connecting seat. A rotating block and a shock absorber are respectively rotatably arranged at the front and rear positions of the support arm. The other end of the linkage plate is rotatably installed in the middle of the rotating block. The front end of the shock absorber is rotatably installed above the rotating block. Retaining rings are respectively arranged on the shock absorber and the shock absorber's shock rod. A shock spring is arranged between the two retaining rings on the shock absorber. A support wheel is also rotatably arranged on the support arm.

[0007] Further, an avoidance groove is formed at the front end of the support arm, and the rotating block is located in the avoidance groove.

[0008] Further, two pairs of fixing blocks are arranged up and down on the gas cylinder bracket, and a strap for binding the medical gas cylinder is arranged between the fixing blocks of the same pair.

[0009] Further, the gas cylinder bracket is respectively provided with a base and a plurality of limiting plates in the height direction, and an arc-shaped opening is formed in the middle of the limiting plate.

[0010] Further, an arc-shaped limiting opening is formed on the base.

[0011] The beneficial effect of the present utility model is that when the vehicle frame shakes downward, the linkage plate pushes the rotating block to rotate backward. In this process, the shock absorber rod contracts, and at the same time, the shock spring gradually contracts. Under the action of the shock spring, the amplitude of the up-and-down shaking of the vehicle frame can be reduced, thereby avoiding a large collision between the medical gas cylinder and the vehicle frame.

[0016] In order to make the patent purpose, technical solution and advantages of the present utility model clearer, the following further describes the present utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] In order to illustrate the technical solution described in the present utility model, the following is illustrated by specific embodiments.

[0018] For the convenience of description, only the parts related to the embodiments of the present utility model are shown.

[0019] Combined with Figures 1-4As shown in the figure, the medical gas cylinder trolley includes a frame 1. A pair of rollers 2 are rotatably provided at the bottom of the frame 1. A gas cylinder bracket 3 is provided on the front of the frame 1, and a connecting frame 4 is provided on the back. A connecting seat 5 is provided on the connecting frame 4. A support arm 6 and a linkage plate 7 are respectively rotatably provided on the connecting seat 5. Rotating blocks 8 and shock absorbers 9 are respectively rotatably provided at the front and rear positions of the support arm 6. The other end of the linkage plate 7 is rotatably installed in the middle of the rotating block 8. The front end of the shock absorber 9 is rotatably installed above the rotating block. Retaining rings 11 are respectively provided on the shock absorber 9 and the shock absorber rod 10 of the shock absorber 9. A shock absorber spring 12 is provided between the two retaining rings on the shock absorber 9. A support wheel 13 is also rotatably provided on the support arm.

[0020] In clinical medicine, medical gas cylinders are essential medical devices in surgeries and first aids. When using this medical gas cylinder trolley to carry a medical gas cylinder, the gas cylinder bracket is in the initial position, and the bottom of the gas cylinder bracket contacts the ground. Medical staff then lift the medical gas cylinder onto the gas cylinder bracket and fix the medical gas cylinder. Then, rotate the frame backward until the support wheel contacts the ground. At this time, medical staff can push the medical gas cylinder trolley to move the medical gas cylinder to the required position.

[0021] The medical gas cylinder trolley has a shock absorption function. When the medical gas cylinder trolley shakes up and down during the process of carrying a medical gas cylinder due to road conditions or other reasons, at this time, under the shock absorption effect of the shock absorber, the amplitude of the up and down shaking of the frame can be reduced, thereby preventing the medical gas cylinder from shaking violently and colliding with the frame.

[0022] When the frame shakes downward, the linkage plate pushes the rotating block to rotate backward. During this process, the shock absorber rod of the shock absorber contracts, and at the same time, the shock absorber spring gradually contracts. Under the action of the shock absorber spring, the amplitude of the up and down shaking of the frame can be reduced, thereby preventing the medical gas cylinder from colliding with the frame to a large extent. Then the shock absorber spring restores its deformation, and the shock absorber rod of the shock absorber resets. Since the shock absorber is a prior art, it will not be described in detail in this article.

[0023] In this structure, as Figure 2 , a relief groove 19 is formed at the front end of the support arm 6, and the rotating block 8 is located in the relief groove 19. The relief groove serves to avoid the rotating block, enabling the rotating block to rotate normally.

[0024] As a preferred structure, as Figure 4 , the gas cylinder bracket 3 is respectively provided with a base 14 and a plurality of limiting plates 15 in the height direction. An arc-shaped opening 16 is formed in the middle of the limiting plate 15. An arc-shaped limiting opening 17 is formed on the base 14.

[0025] After medical staff lift the medical gas cylinder onto the gas cylinder bracket as required, the base supports the medical gas cylinder at this time, and the body of the medical gas cylinder is respectively located in the arc-shaped opening and the limit opening. The arc-shaped opening and the limit opening play a role in limiting the medical gas cylinder to a certain extent, enabling the medical gas cylinder to be more stable during the handling process.

[0026] In addition, there are two pairs of fixing blocks 18 arranged up and down on the gas cylinder bracket 3, and a strap (not shown in the figure) for binding the medical gas cylinder is arranged between the fixing blocks of the same pair.

[0027] In this embodiment, when the medical gas cylinder is transported to the gas cylinder bracket as required, the medical gas cylinder can be tied and fixed to the gas cylinder bracket by using the strap. Installing the medical gas cylinder to the gas cylinder bracket by using the strap is relatively simple and time-saving and labor-saving in the whole process.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the utility model shall be included within the protection scope of the present utility model.
