Abstract
The utility model discloses an easily pull out blind flange, including circular lid, platykurtic handle, cylinder cock body and annular bead, circular lid's inside and outside surface is the plane, the center department of platykurtic handle and circular lid surface is connected, to the direction extension of perpendicular to circular lid's surface, the platykurtic is provided with the elliptic region that is formed by the recess to positive and negative bilateral symmetry on hand, the equidistant recess that is provided with many parallels in the elliptic region, the cylinder cock body is located the center department of circular lid internal surface, extends to the direction of perpendicular to circular lid's internal surface, the lower extreme of cylinder cock body surface is located to the annular bead cover. The utility model discloses an easily pull out blind flange simple structure adopts the handle of human engineering design for the loading and unloading process operation of blind flange is extremely convenient, makes the blind flange seem that the grade is higher, and the blind flange adopts the LLDPE material of environmental protection simultaneously, and comprehensive properties is good, has stronger practicality.
Description
Technical field
The utility model relates to one and easily pulls out blind flange, belongs to flange protective cover technical field.
Background technology
Flange is as part interconnective between pipe and pipe, it may also be useful to very extensive. Flange, in long-distance transport process, extremely easily jolts and damages. Prior art adopt usually blind flange as the safety guard in flange transport and storage process. But current domestic great majority employing is interior plunger type blind flange, this type of blind flange does not have handle, so handling in use are extremely inconvenient, and the material of existing blind flange is mostly LDPE, being easy to rupture when mounted, durability is not good, and practicality is not strong.
Summary of the invention
The purpose of this utility model is to provide one and easily pulls out blind flange, in use loads and unloads be not easy to overcome blind flange in prior art, and the defect that the material of the existing use of blind flange easily ruptures.
For achieving the above object, the technical scheme that the utility model is taked is as follows:
Easily pull out blind flange, comprise circular lid body 1, flats handle 2, round shape cock body 3 and annular bead 4, in described circular lid body 1, outside surface is plane, described flats handle 2 is connected with the center of circular lid body 1 outside surface, direction to the outside surface being perpendicular to circular lid body 1 extends, positive and negative zygomorphy on described flats handle 2 is provided with the elliptic region 21 formed by groove, in described elliptic region 21, spaced set has many parallel grooves 22, described round shape cock body 3 is positioned at the center of circular lid body 1 internal surface, direction to the internal surface being perpendicular to circular lid body 1 extends, described annular bead 4 is sheathed on the lower end of round shape cock body 3 outside surface.
Preferably, the cross-sectional area of described round shape cock body 3 is less than the surface-area of circular lid body 1.
Preferably, the width of described flats handle 2 is less than the diameter of circular lid body 1.
Preferably, the upper limb of described flats handle 2 is the curved edge 23 protruded, and the thickness of described curved edge 23 is greater than the thickness of flats handle 2.
Preferably, described circular lid body 1, flats handle 2, round shape cock body 3 and annular bead 4 are one-body molded by LLDPE material.
The utility model has following useful effect:
(1) the flats handle 2 easily pulling out blind flange of the present utility model makes the handling of blind flange extremely convenient, and adopt ergonomic designs, sense of touch is better, product seems more high-grade, simultaneously due to the existence of flats handle 2 upper groove 22, the frictional force between hand and flats handle 2 can be increased so that it is more convenient to load and unload.
(2) setting of the round shape cock body 3 upper annular flange collar 4 easily pulling out blind flange of the present utility model so that blind flange in use also can mate mutually with the flange of some error, is engaged mutually with flange preferably.
(3) blind flange that easily pulls out of the present utility model obtains by environmental protection LLDPE material is one-body molded, compared with LDPE material, 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.
