Abstract

The utility model discloses a thread gland cover which comprises a cylindrical cover body. One end of the cover body is closed and the other end of the cover body is open. The thread gland cover is characterized in that a plurality of annular fixing rings protruding out of the outer surface of the cover body are arranged on the peripheral wall of the cover body, and an annular gland cover cap is arranged on the periphery wall, close to the open end, of the cover body. According to the thread gland cover, the design of the gland cover cap is improved, so the gland cover cap can be attached to the end face of a tubular material more tightly; the edge of the thread gland cover is designed in an inclined mode, so the probability of collision is reduced, and the phenomenon that the thread gland cover falls off due to the collision is reduced. The thread gland cover has the advantages of being simple in structure, good in use effect and the like.

Description

The thread seal cover

Technical field

The utility model relates to a kind of thread seal cover.

Background technique

Process component during especially tapped cast component, need to carry out shutoff by line up usually before dispatching from the factory, and avoids, into ash, oil-feed dirt, protecting screw thread simultaneously.At present, plug is all the tubular construction that adopts the materials such as PP, PE to make usually, and it,, by interference fit, is inserted in the mouth of pipe, to carry out shutoff.But, often in use, can find the reasons such as Chang Yinwei collision, cause plug to drop.How addressing this problem, the soundness that increases the plug combination is current problem demanding prompt solution.

Summary of the invention

In order to overcome the problems referred to above, the utility model provides a kind of thread seal cover of simple in structure, good fixing effect.

The technical solution of the utility model is to provide a kind of thread seal cover, it comprises columnar body, described body one end sealing, an end opening, it is characterized in that: be provided with the retaining ring of the described cover external surface of protruding from of several annulars on described body periphery wall, near on the periphery wall of described body opening end, be provided with annular big envelope cap.

Preferably, described big envelope cap tilts to the closed end of described body.

Preferably, the angle of described big envelope cap and described body end face is at 15 ° ~ 30 °.

Preferably, the angle of described big envelope cap and described body end face is at 25 °, and test shows, during this angle, big envelope cap and the laminating of pipe fitting end face are best, and can not form the power of larger disengaging pipe fitting end face.

Preferably, the end face at described big envelope hat brim edge place is parallel to the axis of described body.

Preferably, near the stepped part that also is provided with the annular that protrudes from described body periphery wall on the described body periphery wall of described big envelope cap.

Preferably, described thread seal cover is integrated by the PE material, or the common plastics material such as PP, and it is also the material that industry is the most often used.

Thread seal cover of the present utility model has improved the design of big envelope cap, makes its end face of more being close to tube type material, and the edge tilt design, has reduced the probability that collision occurs, thereby has reduced its phenomenon dropped because of collision.The advantages such as thread seal cover of the present utility model has simple in structure, and using effect is good.

The accompanying drawing explanation

Fig. 1 is the sectional view of a kind of thread seal cover of the utility model most preferred embodiment.

Embodiment

Below embodiment of the present utility model is described in further detail.

As shown in Figure 1, a kind of thread seal cover of the present utility model comprises columnar body 10, body 10 1 end sealings, an end opening.Be provided with the retaining ring 12 that protrudes from body 10 outer surfaces of 2 annulars on body 10 periphery walls, be provided with annular big envelope cap 14 near on the periphery wall of body 10 opening ends, near the stepped part 16 that also is provided with the annular that protrudes from body 10 periphery walls on body 10 periphery walls of big envelope cap 14.This thread seal cover is integrated by materials such as PP or PE.It is more than current common structure.

Big envelope cap 14 tilts to the closed end of body 10, and big envelope cap 14 is 25 ° with the included angle A of body 10 end faces, and the end face at big envelope cap 14 places, edge is parallel to the axis of body 10.Thread seal cover of the present utility model in use, body 10 closed ends are inserted in pipe fitting (not shown) center hole, and the inwall of retaining ring 12 meetings and pipe fitting produces extruding, or pushes with the internal thread generation of pipe fitting, to form interference fit, thereby be fixed on pipe fitting.Now, big envelope cap 14 is subject to the extruding of pipe fitting end face and is out of shape backward.Under the effect of the elastic force of big envelope cap 14 self-recovery reset conditions, big envelope cap 14 fits tightly with the pipe fitting end face.Now, the edge tilt of big envelope cap 14, in the pipe fitting end face, collides thereby reduce the probability produced, and reduces the probability that stuffing box gland drops.

Above embodiment is only the utility model a kind of mode of execution wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
