Abstract
The utility model discloses a protruding rib type dust cover for a hole. The protruding rib type dust cover comprises a disc body and a disc edge, wherein the disc body is cylindrical; the disc edge radially extends out of an outer end of the disc body and is of a cap peak shape; a plurality of protruding ribs are axially arranged on the outer circumferential surface of the disc body; and circumferential end faces of the protruding ribs are provided with barbed teeth. The protruding rib type dust cover for the hole, provided by the utility model, can be pressed in an inner hole of a pipe material by a little strength, thus the convenience is brought for the operation; and the pressed dust cover is buckled on the inner wall of the pipe material through a protruding rib wedge and is not easy to fall off, and favorable air permeability and high reliability are realized; and in addition, the dust cover is buckled on the inner wall of the pipe material through the protruding rib wedge, can be suitable for the pipe material with larger change of inner diameter sizes and has strong practicability.
Description
Technical field
The utility model relates to dust cover, specifically is that dust cover is used in a kind of hole of convex tendon type, and it is dustproof that it is especially suitable for use as tubing endoporus such as plastic tube or steel pipe.
Background technique
Tubing such as plastic tube or steel pipe has obtained extensive use in daily life and commercial production, the endoporus of these tubing all is not provided with dustproof construction, and booties such as dust very easily get into the tubing endoporus, and then the usability of tubing is impacted.Though existing technology discloses several kinds of dust covers that the tubing endoporus is used, these dust covers are sealed structure, cause tubing inside to breathe freely, and reliability is low, poor practicability.
Summary of the invention
The purpose of the utility model is: to the deficiency of above-mentioned existing technology, provide a kind of can be effectively dustproof, dust cover is used in the convex tendon type hole that has good gas permeability again.
The technological scheme that the utility model adopts is: dust cover is used in a kind of convex tendon type hole, comprises disk body and web, and said disk body is a cylinder; Said web radially extends from the outer end of disk body, is the brim of a hat shape; Be axially arranged with many convex tendons on the outer peripheral surface of said disk body.
The circumferential end faces of said convex tendon is provided with reverse hook teeth.
Said convex tendon discrete distribution is on the outer peripheral surface of disk body.
Said convex tendon is divided into a plurality of groups, is that the unit discrete distribution is on the outer peripheral surface of disk body with the group.
Every group of convex tendon on the said disk body outer peripheral surface is concatenated into one by horizontal bar.
The outer end end face of said web shutoff disk body.
The beneficial effect of the utility model is: the dust cover of said structure slightly firmly just can be pressed into the tubing endoporus, and easy to operate, the dust cover after being pressed into is buckled in pipe material inner wall through the convex tendon wedge, is difficult for breaking away from, and has air permeability and good, and reliability is high; In addition, dust cover can adapt to internal diameter size and change tubing greatly through convex tendon wedge button pipe material inner wall, and is practical.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is a kind of user mode reference drawing of the utility model.
Code name implication among the figure: 1-web; 2-disk body; 3-convex tendon; 4-horizontal bar; 5-tubing.
Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3: the utility model comprises disk body 2 and web 1.Wherein, disk body 2 is the concave body of tubular, bottom end seal, and the bottom is as the endoporus that stretches into tubing 5, outer end opening.Web 1 radially extends from the outer end of disk body 2, is the brim of a hat shape.On the outer peripheral surface of disk body 2, be axially arranged with many convex tendons 3, the circumferential end faces of every convex tendon 3 is provided with reverse hook teeth.These convex tendons 3 are one group with three, are divided into a plurality of groups, and all groups disperse and are evenly distributed on the outer peripheral surface of disk body 2, and every group of convex tendon 3 is concatenated into one by horizontal bar 4.
After the utility model is pressed into the endoporus of tubing 5; Convex tendon 3 is through the inwall of reverse hook teeth wedge button tubing 5; Web 1 is attached to the end of tubing 5, can prevent effectively that dust from getting into the endoporus of tubing 5, and air in tubing 5 endoporus and extraneous space are through the Clearance Flow of 3 of convex tendons.
The utility model comprises disk body and web.Wherein, disk body is the concave body of tubular, bottom end seal, and the bottom is as the endoporus that stretches into tubing, outer end opening.Web radially extends from the outer end of disk body, is the brim of a hat shape.On the outer peripheral surface of disk body, be axially arranged with many convex tendons, the circumferential end faces of every convex tendon is provided with reverse hook teeth, and these convex tendons disperse and are evenly distributed on the outer peripheral surface of disk body.
What present embodiment was different from embodiment 1 is the layout of convex tendon on disk body, and other is identical with embodiment 1, does not draw separately, and Fig. 1 and Fig. 2 can see reference.
The utility model comprises disk body and web.Wherein, disk body is the concave body of tubular, bottom end seal, and the bottom is as the endoporus that stretches into tubing, outer end opening.The outer end of web shutoff disk body, and web radially extends from the outer end of disk body, and extended disk body is the brim of a hat shape, and disk body and web are combined into the bottle stopper shape.On the outer peripheral surface of disk body, be axially arranged with many convex tendons, the circumferential end faces of every convex tendon is provided with reverse hook teeth.These convex tendons are one group with three, are divided into a plurality of groups, and all groups disperse and are evenly distributed on the outer peripheral surface of disk body, and every group of convex tendon is concatenated into one by horizontal bar.
What present embodiment was different from embodiment 1 is the composite structure of web and disk body, and other is identical with embodiment 1, does not draw separately, and Fig. 1 and Fig. 2 can see reference.
Above-mentioned three embodiments are three preferred version of the utility model, can only can not be used as the protection domain that limits the utility model as understanding the utility model.
