Description

Technical Field

[0001] The present application relates to the technical field of electrical tape production equipment, and in particular to a tile-type inflatable shaft. Background Art

[0002] At present, some rolls of materials, such as cloth rolls or film rolls, are usually stored by rewinding, so air shafts are often used to facilitate the rewinding and disassembly of the rolls.

[0003] In the related technology, a Chinese patent document with authorization announcement number CN209143402U discloses a tile-type inflatable shaft, including a shaft body, which is formed by splicing a plurality of arc-shaped tiles. An airbag that can be inflated and deflated is installed in the shaft body. The airbag part extends from the gap between adjacent tiles and is fixed by positioning protrusions and mounting holes on the tiles. When it is necessary to play a fixing role, the airbag can be inflated so that the part of the airbag located between adjacent tiles protrudes outward to the outside of the circumferential surface of the shaft body.

[0004] However, in the above scheme, after production is completed, in order to reduce the difficulty and time of on-site installation, the airbags and curved tiles usually need to be connected and sold together. During transportation or when the inflatable shaft is disassembled and not in use, the airbags located between the curved tiles are easily damaged, affecting the airtightness of the airbags, thereby causing the entire inflatable shaft to be scrapped. Utility Model Content

[0005] In order to reduce the possibility of the airbag of the inflatable shaft being punctured and damaged when not in use or in transportation, the present application provides a tile-type inflatable shaft.

[0013] By adopting the above technical solution, when the airbag is inflated, the baffle is located in the arc groove, and the arc groove provides a storage space for the baffle. However, after the airbag is deflated, the baffle is controlled to move in the arc groove by the operating member, so that one end of the arc groove moves into the plug-in groove, and the other end of the arc groove is located near the opening of the arc groove. At this time, the baffle covers the operating cavity, thereby protecting the airbag.

[0014] Optionally, the arc groove passes through the end face of the arc tile, and the end of the baffle protrudes from the end face of the arc tile, and a plurality of movable grooves corresponding to each other for the end of the baffle to be inserted and moved are opened on the side wall of the connecting ring, and the operating member is slidably arranged on the connecting ring and one end is fixed to the baffle.

[0015] By adopting the above technical solution, when the operating member slides on the connecting ring, the end of the baffle is driven to move in the movable groove, so that one end of the baffle is inserted into the plug-in groove to close the operating cavity.

[0016] Optionally, a movable groove corresponding to the movable groove one by one is opened on the circumferential surface of the connecting ring, and a plurality of operating members are provided, which are operating rods sliding in the movable groove and fixed to the baffle.

[0017] By adopting the above technical solution, the operating rod is moved in the movable groove, thereby driving the baffle to move in the active groove, and then the baffle is inserted into the plug-in groove to close the operating cavity.

[0018] Optionally, a connecting rod is connected between adjacent operating rods.

[0019] By adopting the above technical solution, when the connecting rod is rotated, multiple operating members can be simultaneously controlled to drive corresponding baffles to close or open the opening of the operating cavity.

[0020] Optionally, the arc-shaped tile and the connecting ring are detachably connected.

[0021] By adopting the above technical solution, the arc-shaped tile and the connecting ring are detachably connected, which can facilitate the dismantling of the shaft body, thereby facilitating the replacement or repair of the damaged airbag.

[0022] Optionally, an extension edge is fixedly connected to the end of the arc-shaped tile, the extension edge abuts against the end face of the connecting ring, and a bolt threadedly connected to the end face of the connecting ring is passed through the extension edge.

[0023] By adopting the above technical solution, the bolts pass through the extension edge and are fixed in the connecting ring, thereby fixing the connecting ring and the arc-shaped tile. The bolt connection method also facilitates the disassembly and assembly of the connecting ring and the arc-shaped tile.

[0024] Optionally, the side wall of the baffle close to the operating chamber is smooth and rounded.

[0025] By adopting the above technical solution, the side wall of the baffle close to the operating cavity is in a smooth rounded shape, which can reduce the possibility of puncturing the airbag when the end of the baffle contacts the airbag.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. During transportation, the gas in the airbag is released, and the convex part is deflated and attached to the inner wall of the operating cavity. The operating member is controlled to drive the baffle to move, so that the baffle closes the opening of the operating cavity, thereby covering the airbag, thereby protecting the airbag and reducing the possibility of the airbag being punctured by external sharp objects when not in use;

[0028] 2. When the airbag is inflated, the baffle is located in the arc groove, which provides a storage space for the baffle. However, after the airbag is deflated, the baffle is controlled to move in the arc groove by the operating member, so that one end of the arc groove moves into the plug-in groove, and the other end of the arc groove is located near the opening of the arc groove. At this time, the baffle covers the operating cavity, thereby protecting the airbag. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-3 This application is described in further detail.

[0034] The present application discloses a tile-type inflatable shaft.

[0035] A tile-type air shaft, referring to Figure 1 and Figure 2 , including a shaft body 1, the shaft body 1 includes a cylindrical airbag 11, a plurality of arc-shaped tiles 12 arranged at intervals are arranged on the outer peripheral wall of the airbag 11, the plurality of arc-shaped tiles 12 form a circular ring, and the gaps between adjacent arc-shaped tiles 12 form an operating cavity 13. After the airbag 11 is inflated, it passes through the gaps and fills the operating cavity 13 to form a convex portion.

[0036] Reference Figure 2 An arc-shaped groove 121 is provided on the side wall of the arc-shaped tile 12. The arc-shaped groove 121 is provided along the length direction of the arc-shaped tile 12 and passes through the end face of the arc-shaped tile 12. A baffle 2 for covering the operating cavity 13 is slidably provided in the arc-shaped groove 121. An insertion groove 122 for inserting the end of the baffle 2 is provided on the other side of the arc-shaped digging piece. The end of the baffle 2 close to the insertion groove 122 is smooth and rounded.

[0037] During transportation or when the inflatable shaft is disassembled and not in use, the airbag 11 between the arc-shaped tiles 12 is easily damaged, which affects the airtightness of the airbag 11, and thus causes the entire inflatable shaft to be scrapped. Therefore, when the airbag 11 is in a deflated state, the baffle 2 is slid in the arc-shaped groove 121 so that the rounded end of the baffle 2 is inserted into the plug-in groove 122, so that the baffle 2 covers the operating cavity 13, thereby protecting the airbag 11 in the operating cavity 13. At the same time, during the movement of the baffle 2, the end of the baffle 2 may touch the airbag 11. The end of the baffle 2 is set to a smooth rounded shape, so that even if the baffle 2 touches the airbag 11, it is not easy for the airbag 11 to be punctured, thereby further protecting the airbag 11.

[0038] Reference Figure 1 and Figure 3 The end of the arc-shaped tile 12 is fixedly connected with an extension edge 3, which abuts against the end surface of the connecting ring 4. The extension edge 3 is penetrated by a bolt 31 which is threadedly connected to the end surface of the connecting ring 4. The bolt 31 realizes the connection between the arc-shaped tile 12 and the connecting ring 4, and the bolt 31 is easy to disassemble, which has a beneficial effect on replacing the damaged airbag 11.

[0039] Reference Figure 1 and Figure 3, the two ends of the shaft body 1 are detachably connected with the connecting ring 4, the two ends of the arc-shaped tile 12 are respectively connected to the end surface of the connecting ring 4, and the end of the airbag 11 passes through the inner cavity of the connecting ring 4 or is connected to the inner cavity of the connecting ring 4, so as to facilitate the inflation of the airbag 11. The connecting ring 4 is provided with a plurality of movable grooves 41 for the end of the baffle 2 to move on the side facing the arc-shaped tile 12, and the movable grooves 41 correspond to the arc-shaped grooves 121 one by one. The end of the baffle 2 is detachably connected with the operating member 5, and the operating member 5 is an operating rod, and the end of the operating rod is threadedly connected to the baffle 2, and the operating rod is perpendicular to the axis of the baffle 2. The outer peripheral wall of the connecting ring 4 is provided with a plurality of movable grooves 42 for the operating rod to slide, and the movable grooves 42 are connected to the arc-shaped grooves 121.

[0040] When the operating rod rotates in the movable groove 42, the end of the baffle 2 is driven to rotate in the movable groove 41, and then the baffle 2 is driven to move in the arc groove 121 until one side of the baffle 2 is inserted into the insertion groove 122, thereby covering the operating cavity 13 and protecting the airbag 11.

[0041] Reference Figure 1 and Figure 3 The ends of the operating rods away from the baffle 2 are connected to the same connecting rod 6, and the connecting rod 6 is in a circular ring shape. When the connecting rod 6 is rotated, the several operating rods can be controlled to move in the corresponding moving grooves 42 at the same time, thereby controlling the several baffles 2 to close the corresponding operating chambers 13, thereby improving the efficiency of closing the operating chambers 13.

[0042] The implementation principle of a tile-type inflatable shaft in an embodiment of the present application is: rotate the connecting rod 6 so that a plurality of operating rods rotate in the movable groove 42, and the operating rod drives the end of the baffle 2 to rotate in the movable groove 41, thereby driving the baffle 2 to move in the arc groove 121 until one side of the baffle 2 is plugged into the plug-in groove 122, thereby covering the operating cavity 13 and protecting the airbag 11.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
