The inner support 100 comprises a support part 110, and the flexible outer sleeve 200 comprises a connecting part 210, a first annular fixing part 220, and a second annular fixing part 230. The first annular fixing part 220 is connected to the first end of the connecting part 210, and the second annular fixing part 230 is connected to the second end of the connecting part 210. The connecting part 210 is wrapped around the support part 110 to fix the positions of the first annular fixing part 220 and the second annular fixing part 230 when the support part 110 is bent.

[0033] The quick connecting support device for the container main body and the cover body provided by the utility model comprises an inner support 100 and a flexible outer sleeve 200. When in use, the first annular fixing part 220 and the second annular fixing part 230 provided at the two ends of the flexible outer sleeve 200 can be connected to the cover body and the neck part of the container main body, respectively. Meanwhile, the support part 110 of the inner support 100 located in the connecting part 210 of the flexible outer sleeve 200 can fix the positions of the first annular fixing part 220 and the second annular fixing part 230 by bending. Whether the cover body is on the container main body or separated from the container main body, the position of the cover body can be fixed, which can effectively prevent the cover body from loosening, falling off, or even causing impact damage to the container main body, and can improve the stability and safety factor of the experimental device.

[0034] Specifically, referring to Figure 5As shown, in use, first annular fixing portion 220 of flexible outer sleeve 200 is sleeved on the cover body, and second annular fixing portion 230 of flexible outer sleeve 200 is sleeved on the neck of the container body, so that the cover body is connected with the container body through connecting portion 210, first annular fixing portion 220 and second annular fixing portion 230 of flexible outer sleeve 200. When the cover body is covered on the container body, supporting portion 110 can assist in fixing the positions of first annular fixing portion 220 and second annular fixing portion 230 under the action of plastic deformation, so as to prevent first annular fixing portion 220 and second annular fixing portion 230 from moving, thereby improving the stability of the cover body when being fixed. When the cover body is removed from the container body, supporting portion 110 can also assist in fixing the positions of first annular fixing portion 220 and second annular fixing portion 230 under the action of plastic deformation, so as to prevent first annular fixing portion 220 and second annular fixing portion 230 from moving, thereby improving the stability of the cover body when being separated from the container body.

[0035] In flexible outer sleeve 200, the sizes of connecting portion 210, first annular fixing portion 220 and second annular fixing portion 230 can be set according to actual needs (such as adapting to different experimental equipment), and the present application does not make specific limitation thereon.

[0037] In addition, the materials of flexible outer sleeve 200 and inner supporting piece 100 can be selected according to actual needs (environment of experimental equipment). For example, when the connecting device needs to be used in a high-temperature or corrosive environment, flexible outer sleeve 200 can be made of high-temperature-resistant and corrosion-resistant materials.

[0038] Referring to Figures 1 to 4 As shown, according to some embodiments of the present application, inner supporting piece 100 further comprises first auxiliary fixing portion 120, first auxiliary fixing portion 120 is connected with one end of supporting portion 110 close to first annular fixing portion 220, and first annular fixing portion 220 is covered outside first auxiliary fixing portion 120.

[0046] It can be understood that in some embodiments, when the material strength of the first auxiliary fixing arm 121 is low, the length of the first auxiliary fixing arm 121 can be greater than half of the corresponding side of the first annular fixing part 220; when the material strength of the first auxiliary fixing arm 121 is high, the length of the first auxiliary fixing arm 121 can be less than half of the corresponding side of the first annular fixing part 220.

[0047] Referring to Figures 1 to 4 As shown in the drawings, according to some embodiments of the present application, the inner support 100 further includes a second auxiliary fixing part 130, and the second auxiliary fixing part 130 is connected with one end of the support part 110 close to the second annular fixing part 230, and the second annular fixing part 230 is wrapped outside the second auxiliary fixing part 130.

The second auxiliary fixing part 130 can be connected to the support part 110 by welding, or the second auxiliary fixing part 130 and the support part 110 can be integrally provided.

[0050] Referring to Figures 1 to 4 According to some embodiments of the present application, the second auxiliary fixing part 130 includes two second auxiliary fixing arms 131, one of which extends along the first side of the second annular fixing part 230, and the other of which extends along the second side of the second annular fixing part 230.

[0051] By configuring the second auxiliary fixing part 130 as two second auxiliary fixing arms 131 extending along the two sides of the second annular fixing part 230, the two second auxiliary fixing arms 131 can be used to assist in fixing the second annular fixing part 230 on both sides at the same time, thereby improving the connection stability of the second annular fixing part 230 and the container body.

[0052] It should be noted that the extension lengths of the two second auxiliary fixing arms 131 can be the same or different.

[0053] According to the quick connection support device for the container body and the cover body provided by the present application, the end of the second auxiliary fixing arm 131 is located at the middle of the first side of the second annular fixing part 230, and the end of the second auxiliary fixing arm 131 is located at the middle of the second side of the second annular fixing part 230.

[0054] By setting the ends of the two second auxiliary fixing arms 131 at the middle of the first side and the second side of the second annular fixing part 230, respectively, the remaining part of the second annular fixing part 230 still has better flexibility under the premise of ensuring that the two second auxiliary fixing arms 131 can achieve better auxiliary fixing effect, which facilitates the close fitting of the second annular fixing part 230 on the neck of the container body.

[0055] It can be understood that, in some embodiments, when the material strength of the second auxiliary fixing arm 131 is low, the length of the second auxiliary fixing arm 131 can be greater than half of the corresponding side of the second annular fixing portion 230; when the material strength of the second auxiliary fixing arm 131 is high, the length of the second auxiliary fixing arm 131 can be less than half of the corresponding side of the second annular fixing portion 230.

[0056] It should be noted that the first auxiliary fixing portion 120 or the second auxiliary fixing portion 130 can be arranged on the support portion 110 alone, or the first auxiliary fixing portion 120 and the second auxiliary fixing portion 130 can be arranged on the support portion 110 simultaneously.

[0057] In some embodiments, when the first auxiliary fixing portion 120 and the second auxiliary fixing portion 130 are arranged on the support portion 110 simultaneously, the size specifications of the two first auxiliary fixing arms 121 in the first auxiliary fixing portion 120 and the two second auxiliary fixing arms 131 in the second auxiliary fixing portion 130 can be made consistent, so as to reduce the processing and manufacturing difficulty of the inner support 100.

[0059] According to some embodiments of the utility model, the inner support 100 is made of iron, iron alloy, copper, copper alloy, aluminum or aluminum alloy material.

[0060] By making the inner support 100 of iron, iron alloy, copper, copper alloy, aluminum or aluminum alloy material, the iron, iron alloy, copper, copper alloy, aluminum and aluminum alloy material has better plastic deformation ability, especially the copper alloy and the aluminum alloy, which has excellent plasticity and low work hardening rate, and can be easily formed through stretching, bending, stamping and other processing technologies.

[0061] Of course, the inner support 100 can also use other new materials that have both support strength and bendability, such as glass fiber reinforced plastic, carbon fiber reinforced plastic, polycarbonate, polyether ether ketone, spring steel, titanium alloy, polyurethane, thermoplastic polyurethane, flexible composite material, glass fiber, engineering plastic, etc.

[0062] According to some embodiments of the utility model, the flexible outer sleeve 200 is a high-temperature-resistant and chemical-corrosion-resistant flexible outer sleeve 200.
