Abstract

The utility model discloses a kind of core pipe plug, when solving stationary pipes insertion core pipe, the problem that stationary pipes can be broken, its drip irrigation device is a kind of plug, comprise plug body, described body is provided with stationary pipes, and the circumferential end surfaces of described stationary pipes forms flange to the turnover of direction, the center of circle.The utility model has the advantages that by being provided with flange on the section of stationary pipes, flange strengthens the intensity of the end face of stationary pipes, and prevent when stationary pipes inserts core pipe, stationary pipes is broken.

Description

Core pipe plug

Technical field

The utility model relates to film conveyance field, and more particularly, it relates to a kind of core pipe plug.

Background technology

In modern production process, usually adopt core pipe to carry out winding to it for band-type product such as various film, adhesive tape or paper and store, facilitate storage and the transport of film or paper etc.The products such as film are wound on core pipe and carry out storing or transporting by core pipe usually, but in transportation, distortion or wearing and tearing may be caused due to reasons such as extruding or frictions in the two ends of product.

In prior art, application number be 201120072750.1 patent of invention carry out protective film by adding plug at the two ends of core pipe, plug comprises stationary pipes, stationary pipes is inserted in core pipe and is played fixing effect to core pipe, when rolling up installation of core pipe, because core pipe has reeled the film of multilayer, so the inwall of core pipe not easily deforms, but the tube wall of stationary pipes is thinner, when stationary pipes starts to insert core pipe, the head of stationary pipes easily deforms, breaking of stationary pipes is easily caused time serious, the stationary pipes of breaking not only fixed effect is poor, the stationary pipes of simultaneously breaking can destroy the inwall of core pipe.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of core pipe plug preventing stationary pipes from breaking.

For achieving the above object, the utility model provides following technical scheme: a kind of core pipe plug, comprises plug body, and described body is provided with stationary pipes, and the end face of described stationary pipes has extended internally flange.

As preferably, the end face of described stationary pipes is provided with fillet.

As preferably, the inner tubal wall circumference of described stationary pipes is distributed with several reinforced ribs, and described in each, one end of reinforced rib is connected with flange, and reinforced rib described in each extends along the axis of stationary pipes.

As preferably, described plug body is also provided with stationary pipes the center concentric ring that is the center of circle, the circumferential end surfaces of described concentric ring and stationary pipes forms the groove that the end face for core axle inserts.

As preferably, the diameter of described stationary pipes is 70 millimeters.

As preferably, the width of described flange is 5.5 millimeters.

The utility model has following advantage compared to existing technology: by being provided with flange on the section of stationary pipes, and flange strengthens the intensity of the end face of stationary pipes, and prevent when stationary pipes inserts core pipe, stationary pipes is broken.

Detailed description of the invention

With reference to accompanying drawing, the utility model is described further.

As shown in Figure 1, when core pipe 2 is packed, the stationary pipes 11 of plug body 1 is inserted in the inwall of core pipe 2, and the right and left of core pipe 2 is respectively inserted with two plug bodies 1.

As shown in Figure 2, the shape of plug body 1 can be cuboid, square or round platform, in the present embodiment, the shape of plug body 1 is preferably cuboid, the center of the end face of cuboid is provided with stationary pipes 11, the circumferential end surfaces of stationary pipes 11 radially extends and forms flange 111 to the turnover of direction, the center of circle, flange 111 serves the effect of the end face strength strengthening stationary pipes 11, the deflection of the end face slowing down stationary pipes 11 after stressed, the inner tubal wall circumference of stationary pipes 11 is distributed with several reinforced ribs 12, one end of reinforced rib 12 is connected with flange 111, reinforced rib 12 extends along the axis of stationary pipes 11, owing to stationary pipes 11 will be born the weight of the product on core pipe 2, the reinforced rib 12 added at the inwall of stationary pipes 11 can strengthen the structural strength of stationary pipes 11, prevent stationary pipes 11 from breaking, wearing and tearing are produced in the inner side of core pipe 2 after preventing stationary pipes 11 from breaking.

As shown in Figure 3, the circumferential end surfaces of stationary pipes 11 is provided with fillet 112, the external diameter of stationary pipes 11 is 70 millimeters, it is 5.5 millimeters that the circumferential end surfaces of stationary pipes 11 is radially extended with flange 111 with the distance of the inwall of stationary pipes 11, plug body 1 is also provided with stationary pipes 11 center be the center of circle concentric ring 13, the groove that the end face that described concentric ring 13 and the circumferential end surfaces of stationary pipes 11 form confession core pipe 2 inserts.

The internal diameter of the small core pipe 2 of general production is 72 millimeters, and the external diameter of stationary pipes 11 adopts 70 millimeters stationary pipes 11 can be facilitated to insert in core pipe 2; In like manner, be 5.5 millimeter through test flange 111 to the distance of stationary pipes 11 inwall, stationary pipes 11 not easily deforms, if be less than 5.5 millimeters, the structural strength of stationary pipes 11 reduces, if be greater than 5.5 millimeters, when stationary pipes 11 is fit into core pipe 2, the end of stationary pipes 11 is really up to the mark, easily causes breaking of core pipe 2.

In installation process, fillet 112 can play the effect of guiding when mounted, and fillet 112 is when the contact internal walls with core pipe 2 simultaneously, and fillet 112 reduces the friction with core pipe 2 inwall; When core pipe 2 is installed, the tube wall wall of the dual-side of core pipe 2 can block by groove, and prevent core pipe 2 after installation terminates, core pipe 2 shakes in the radial direction of stationary pipes 11, the stationarity of impact transport.

The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
