Abstract

The utility model discloses a take tube hole shield of O type circle, including lid, handle and O type circle, the drum of lid for having the plane closing cap, the handle connect perpendicularly in the center of the surface of plane closing cap, O type circle is located the inside of lid to connect perpendicularly in the center of the internal surface of plane closing cap, the bottom edge of O type circle is higher than the bottom edge of lid for O type circle contracts in the inside of lid, lid and handle are by LLDPE material integrated into one piece, O type circle is made by elastic material. The utility model discloses a take tube hole shield of O type circle had both had interior stopper type stopple and had combined inseparable characteristics, had the sealed effectual characteristics of handhole door again to the lid of LLDPE material and handle intensity are high, toughness is good, the rigidity is strong, heat -resisting, cold -resistant, still have good resistant environmental stress fracture and be able to bear or endure performance such as tear strength, the O type of being made by elastic material encloses and has further improved sealed effect.

Description

The pore dust guard of with o circle

Technical field

The utility model relates to the pore dust guard of a kind of with o circle, belong to pore dust-proof, anti-blocking, protection technical field.

Background technology

The pore of various pipe fitting is stacked in storage or in outdoor stacking process, is very easily stained with dust and mud, or some little sandstones easily enter in this some holes and cause blocking, and subsequent construction causes great inconvenience. Prior art is normally needing the interior plunger type stopple using LDPE material in dust-proof pore, although solving dust-proof problem, but the handling of interior plunger type stopple are inconvenient, waterproof poor sealing, and LDPE material ageing resistance is not strong, time easy cracking of a specified duration so that existing stopple is difficult to meet user demand.

Summary of the invention

The purpose of this utility model is to provide the pore dust guard of a kind of with o circle, to overcome the existing defects such as interior plunger type stopple easily ftractures, stopping property is poor, handling are inconvenient.

For achieving the above object, the technical scheme that the utility model is taked is as follows:

The pore dust guard of with o circle, comprise lid body 1, handle 2 and O 3, described lid body 1 is for having the cylinder of plane cover, described handle 2 is vertically connected at the center of the outside surface of described plane cover, described O 3 is positioned at the inside of lid body 1, and it is vertically connected at the center of the internal surface of described plane cover, the bottom margin of described O 3 is higher than the bottom margin of lid body 1, O 3 is made to shrink in the inside of lid body 1, described lid body 1 and handle 2 are one-body molded by LLDPE material, and described O 3 is made up of resilient material.

Preferably, described handle 2 is flat shape strip, and its surface is provided with multiple parallel anti-skidding rib 21, and the direction of described anti-skidding rib 21 is perpendicular to the length direction of described flat shape strip handle 2.

Preferably, the thickness of described handle 2 end is greater than the thickness of other parts of handle 2.

The utility model has following useful effect:

(1) the pore dust guard of with o circle of the present utility model is in use, lid body is enclosed within the outer wall of pipe fitting, and O is filled in pore, and the envelope lid of lid body is completely closed by pipe fitting end, both there is interior plunger type stopple and combined feature closely, there is again the feature of hole lid good sealing effect.

(2) pore dust guard of the present utility model has handle, is convenient to handling, and the setting of anti-skidding rib further increases frictional force.

(3) the lid body of pore dust guard of the present utility model and handle adopt LLDPE material one-body molded, there is the advantages such as intensity height, good toughness, rigidity be strong, heat-resisting, cold-resistant, also there is the performances such as good resisting environmental stress and cracking, tear-resistant intensity, O is made up of resilient material, further improves sealing effect.
