Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a combined vacuum tin paper tube. Background Art

[0002] A vacuum tinfoil tube is usually composed of an inner tube, an outer tube and a plastic sleeve. Through holes are provided on the surfaces of the inner tube and the outer tube. During the production process, it is necessary to draw a vacuum through both ends of the inner tube so that the tinfoil is adsorbed on the surface of the tube. Since there is a certain gap between the inner tube and the outer tube, there is no static electricity.

[0003] At present, when using vacuum tin foil tubes, there is a lack of an anti-falling mechanism. Usually, before the combined vacuum tin foil tube is used, it is necessary to pre-connect the inner tube and the outer tube through a plastic sleeve. However, in the actual operation process, due to the wear caused by friction, a large gap will still be generated between the inner tube, the outer tube and the plastic sleeve, resulting in difficulty in ensuring the stability of the combined use. Therefore, a combined vacuum tin foil tube is proposed to increase the anti-falling mechanism, improve the stability of the combined use of the vacuum tin foil tube, and at the same time improve the sealing of the suction vacuum, thereby improving the use effect.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] In order to facilitate the addition of an anti-falling mechanism and improve the stability of the vacuum tin paper tube combination, thereby improving the use effect, such as Figure 1-3 As shown, the utility model discloses a combined vacuum tin foil tube, comprising an inner tube 1, an outer tube 2 and a plastic sleeve 3, wherein the outer tube 2 is sleeved around the outer periphery of the inner tube 1, and the outer peripheries of both ends of the inner tube 1 and the inner sides of the outer tube 2 are both provided with plastic sleeves 3;

[0031] The plastic sleeve 3 comprises an extension seat 301 , one end of which is provided with a connection portion 302 , and a rubber strip 303 is glued and fixed to the periphery of the connection portion 302 through a reserved thread groove.

[0032] When in use, an auxiliary anti-falling mechanism can be added by extending the seat 301, the connecting part 302 and the rubber strip 303, which can not only improve the stability of the vacuum tin foil tube disassembly and assembly, but also improve the sealing performance, thereby ensuring the adsorption effect of the vacuum tin foil.

[0033] In order to improve the flexibility of the use of the inner tube, for example, Figure 1 , Figure 2 As shown, the utility model also includes that the inner tube 1 includes a short section 101, and the two ends of the short section 101 are connected to the sleeve 102 by welding. The outer periphery of the sleeve 102 is provided with an extension tube 103, and the outer surface of the sleeve 102 is provided with an external thread 104, and the extension tube 103 is threadedly connected to the sleeve 102 through the external thread 104.

[0034] When in use, the short section 101, the sleeve 102, the extension tube 103 and the external thread 104 can be connected by thread, thereby increasing the flexibility of the inner tube 1 and meeting different length requirements.

[0035] For example, Figure 2 As shown, the utility model also includes that the bottom of the extension seat 301 is located at the periphery of the connecting portion 302 and is fixedly installed with a gasket 304 through a slot.

[0036] When in use, the gasket 304 is used to improve the sealing between the plastic sleeve 3 and the outer tube 2 .

[0037] For example, Figure 2 As shown, the utility model also includes that a second gasket 305 is fixedly installed at the bottom of the connecting portion 302 through a slot.

[0038] When in use, the second gasket 305 facilitates improving the installation stability of the connecting portion 302 .

[0039] For example, Figure 3 As shown, the utility model also includes that the surfaces of the short section 101 and the extension tube 103 are both provided with waist-shaped holes 105 , one end of the extension tube 103 is provided with a connecting tube 106 , and the surface of the connecting tube 106 is provided with a connecting hole 107 .

[0040] When in use, the waist-shaped hole 105, the connecting tube 106 and the connecting hole 107 facilitate connection to an external vacuum pumping device for vacuum pumping operation.

[0041] For example, Figure 4 As shown, the utility model further includes that the surface of the outer tube 2 is provided with an annular fine hole 201 , and the inner surface of the outer tube 2 is provided with a thread groove 202 corresponding to the rubber strip 303 .

[0042] When in use, the threaded groove 202 facilitates the rubber strip 303 to be rotated and inserted, thereby completing the auxiliary assembly splicing.

[0043] For example, Figure 2 As shown, the present invention also includes that the extension seat 301 and the connecting portion 302 are both made of plastic.

[0044] When in use, it is convenient to reduce the production cost of the vacuum tin paper tube.

[0045] When the utility model is in use, firstly, according to the actual use length requirement, the outer thread 104 is used to perform threaded fixed connection processing with the extension tube 103 respectively, so as to adjust the use length of the inner tube 1, and then the corresponding outer tube 2 is selected to be sleeved on the outer periphery of the inner tube 1, and then the connecting part 302 of the plastic sleeve 3 is sleeved on the outer periphery of the connecting tube 106 and pushed to one side of the outer tube 2, and the extension seat 301 is rotated so that the rubber strip 303 on the outer surface of the connecting part 302 is slowly inserted into the thread groove 202, thereby completing the combined installation operation of the vacuum tin foil tube. Through the setting of the plastic sleeve 3, not only the stability of the combined connection can be improved, but also the rubber strip 303, the gasket 304 and the second gasket 305 can be used to reduce the gap between the inner tube 1, the outer tube 2 and the plastic sleeve 3, so as to improve the stability of vacuuming. Finally, the operator connects the vacuuming equipment through the connecting tube 106 to extract the air in the inner tube 1, so that the tin foil is adsorbed on the surface of the outer tube. The overall structure is simple and easy to disassemble and assemble, and the use is more stable and reliable.
