DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0024] Please refer to Figures 1-6 A laboratory gas cylinder carrying and fixing device, including handle 1, main bottom plate 2 installed at the lower end of handle 1 and main arc plate 3 installed on main bottom plate 2, the upper surface of main bottom plate 2 close to the side of handle 1 is fixedly connected with support plate 8, the two sides of support plate 8 are both connected with auxiliary storage assembly, the other end of two auxiliary storage assemblies are both connected with main arc plate 3, and two auxiliary storage assemblies are respectively located on the two sides of main arc plate 3.

[0025] As Figures 1 to 6 Indicated, the laboratory gas cylinder carrying and fixing device in the utility model needs to carry only one gas cylinder when using, only needs to place the gas cylinder on main bottom plate 2, then inclines the carrying vehicle by pressing handle 1, can move the carrying vehicle by two wheels; if multiple gas cylinders need to be carried, only needs to pull two auxiliary storage assemblies to the two sides of main arc plate 3 (if only two gas cylinders need to be carried, only one side of auxiliary storage assembly can be pulled out), when auxiliary storage assembly is pulled out, new space can be left between auxiliary storage assembly and main arc plate 3, at this time, other gas cylinders can be placed in this position, so that the purpose of carrying multiple gas cylinders at the same time can be realized.

[0026] It needs to be specially pointed out here that: the laboratory gas cylinder carrying and fixing device in the utility model is similar in structure to the existing laboratory gas cylinder carrying and fixing device, such as the patent of a gas cylinder carrying tool with publication number CN219277513U.

[0027] Please mainly refer to Figures 1-6The auxiliary storage assembly comprises a secondary arc plate 4 and a plurality of connecting plates 5. The inner side wall of the secondary arc plate 4 is matched against the outer side wall of the primary arc plate 3. One end of the secondary arc plate 4 is fixedly connected with one end of the plurality of connecting plates 5. The other end of the plurality of connecting plates 5 is connected with the support plate 8. The support plate 8 is provided with a plurality of sliding openings 801 on the side close to the primary arc plate 3. The plurality of connecting plates 5 are fixedly connected with a plurality of sliding blocks 10 on the side away from the primary arc plate 3. The outer walls of the plurality of sliding blocks 10 are slidably connected with the inner walls of the plurality of sliding openings 801. The plurality of connecting plates 5 in the two auxiliary storage assemblies are arranged in a staggered manner.

[0028] More specifically, when a plurality of gas cylinders need to be carried, the secondary arc plate 4 is only pulled to one side. After the secondary arc plate 4 moves, the connecting plate 5 will also displace together. The connecting plate 5 will not fall off due to the effect of the sliding opening 801 and the sliding block 10. In addition, the secondary arc plate 4 can be supported when the gas cylinder is placed inside the secondary arc plate 4, thereby increasing the overall support of the secondary arc plate 4.

[0029] Please refer to Figures 1-6 The bottom surface of the secondary arc plate 4 is fixedly connected with a secondary bottom plate 9. The bottom surface of the secondary bottom plate 9 is slidably connected with the upper surface of the primary bottom plate 2. The upper surface of the primary bottom plate 2 is provided with a storage opening 201. The outer wall of the secondary bottom plate 9 is slidably connected with the inner wall of the storage opening 201.

[0030] More specifically, by arranging the secondary bottom plate 9 and the storage opening 201, a supporting force can be added to the bottom of the gas cylinder when the gas cylinder is placed in the secondary arc plate 4, thereby preventing the gas cylinder from falling from the bottom of the gas cylinder. By arranging the storage opening 201, the secondary bottom plate 9 can be stored when the secondary arc plate 4 is not needed.

[0031] Please refer to Figures 1-6 The side of the secondary arc plate 4 away from the connecting plate 5 is rotatably connected with a plurality of limiting strips 7. The other end of the plurality of limiting strips 7 is provided with a limiting opening 701. The surface of the primary bottom plate 2 is fixedly connected with a plurality of limiting blocks 6. The inner wall of the limiting opening 701 is slidably connected with the outer wall of the limiting block 6.

[0032] More specifically, by arranging the limiting strip 7 and the limiting block 6, the limiting opening 701 at the other end of the limiting strip 7 can be sleeved on the limiting block 6 after the gas cylinder is placed in the primary arc plate 3 and the secondary arc plate 4, thereby limiting the side of the gas cylinder away from the primary arc plate 3 and the secondary arc plate 4, and preventing the gas cylinder from falling from this side.

[0033] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
