Abstract

The utility model discloses a threaded blind plate, which consists of a blind plate body, a circular lug boss and through holes, wherein the blind plate body is shaped like a round cake; the circular lug boss is arranged above the blind plate body; a thread is uniformly distributed on the lateral surface of the circular lug boss; the through holes are uniformly distributed between the outer edges of the blind plate body and the circular lug boss; the diameter of the circular lug boss is slightly smaller than that of the blind plate body; a connecting line of the bottom surface circle centers of the circular lug boss and the blind plate body is perpendicular to the bottom surface of the blind plate body. According to the threaded blind plate, the firmness and pressure resistance of the blind plate are improved.

Description

Screw thread blind plate

Technical field:

The utility model relates to a kind of blind plate, relates in particular to the novel blind plate of screw thread.

Background technique:

Blind plate is a kind of part that is used for blocking pipe mouth.At present, in the pipeline of industry-by-industry every field, all used blind plate.In chemical industry, often can touch some has pollution to environment, human body is had to the liquid of harm, and these liquid are carried particularly careful.In the prior art, blind plate is only connected with pipeline by bolt, although very simple in operation and dismounting, yet when the pressure of the liquid of carrying is excessive, be easy to blind plate to cause huge impact, make these to environment, have pollution, to human body, have the liquid of harm can flow out pipeline, this will cause imponderable injury to environment and the mankind.Therefore, very important of the soundness of blind plate.

Model utility content:

For the deficiency in appeal technology, the utility model has designed a kind of screw thread blind plate, blind plate body, round boss, through hole, consists of, and blind plate body is round pie, and described blind plate body top is provided with round boss; The side of described round boss is uniform-distribution with screw thread.

As further improvement of the utility model, dispersed through hole between the outward edge of described blind plate body and the outward edge of described round boss.

As further improvement of the utility model, the diameter of described round boss is slightly less than the diameter of described blind plate body.

As further improvement of the utility model, described round boss the center of circle, bottom surface and the line in the center of circle, bottom surface of described blind plate body vertical with the bottom surface of blind plate body.

The beneficial effects of the utility model: the soundness and the anti-pressure ability that have increased blind plate.

Accompanying drawing explanation:

Fig. 1 is the plan structure figure of screw thread blind plate;

Fig. 2 is the main TV structure figure of screw thread blind plate;

1-blind plate body wherein, 2-round boss, 3-through hole, 4-screw thread.

Embodiment:

The utility model has designed a kind of screw thread blind plate, by blind plate body 1, and round boss 2, through hole 3 forms.Blind plate body 1 is round pie, and the top of described blind plate body 1 is provided with round boss 2.Described through hole 3 is dispersed between the outward edge of blind plate body 1 and the outward edge of round boss 2.Bolt is fixedly connected through through hole 3 and pipeline opening, and this measure makes the soundness of blind plate obtain basic assurance.The side of described round boss 2 is uniform-distribution with screw thread 4.The screw thread 4 of the distribution on round boss 2 is tightly fixedly connected with the internal thread that pipeline opening distributes, and this measure makes the soundness of screw thread blind plate that the variation of matter occur.Round boss screw thread 4 be connected with the internal thread of pipeline with bolt by bore a hole 3 with the soundness that has increased greatly blind plate being connected of pipeline opening, make the conveying of chemical liquid become safe and reliable.

As further improvement of the utility model, the diameter of described round boss 2 is slightly less than the diameter of described blind plate body 1.

As further improvement of the utility model, described round boss 2 the center of circle, bottom surface and the line in the center of circle, bottom surface of described blind plate body 1 vertical with the bottom surface of blind plate body 1.Uniform sequential distribution and arrangement make whole screw thread blind plate stress balance, have increased greatly soundness and the anti-pressure ability of screw thread blind plate, and uniform sequential distribution makes novel blind plate become more attractive in appearance.

Claims

1. a screw thread blind plate, by blind plate body, round boss, through hole, formed, blind plate body is round pie, the top of described blind plate body is provided with round boss, the side of described round boss is uniform-distribution with screw thread, the diameter of described round boss is slightly less than the diameter of blind plate body, described round boss the center of circle, bottom surface and the line in the center of circle, bottom surface of blind plate body vertical with the bottom surface of blind plate body, it is characterized in that: dispersed through hole between the outward edge of described blind plate body and the outward edge of described round boss.
