Two disk body hinged joint, the left end just is fixed like this, close the back, rotate the bolt, the extrusion piece that the bolt drove the round platform type supports the extrusion inclined plane on the disk body of downside, thereby it is fixed, when here is fixed, only need fixed a bolt can, the time is saved, when opening, rotate the bolt, the extrusion piece breaks away from the extrusion inclined plane, the disk body of upside can overturn, rotatory length just is less like this, the time is shorter, the time is saved, and simultaneously, the bolt is always connected on the connecting plate, and the joint strength is guaranteed.

Description

Flange convenient to open

Technical Field

The utility model relates to a convenient field is opened to the flange, specifically is a convenient flange of opening.

Background

The flange is very common in our life, and many places need be used, and some places are opened often not, and some places then need often be opened, maintain or the inspection, to the flange of often opening, a lot of adoption bolted connections on the market, like this, only the bolt is unscrewed completely, just can take off, and, two at least bolts, the comparison delays the time, if the screw in is less, can save the time of unscrewing, but, the easy pine takes off, consequently, need one kind and fixed convenient, by can save the flange of opening and the time of screwing.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a convenient flange of opening to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: a flange convenient to open comprises a plate body and a connecting pipe connected to the plate body, wherein the plate body is divided into an upper plate body and a lower plate body, and a sealing gasket is arranged between the two plate bodies;

the left ends of the two disc bodies are hinged, the right end of the disc body on the upper side is fixed with a connecting plate which is bent downwards to form a right angle, and the connecting plate is connected with a screwing mechanism which is fixed through the lower end face of the disc body extruded from one side to the lower side.

Preferably, the screwing mechanism comprises a leftward bolt in threaded connection with the connecting plate, and a small end of the leftward bolt, which is in circumferential contact with the lower end surface of the lower disc body, is mounted at the left end of the bolt and is in a truncated cone shape leftward.

Preferably, the bolt is rotatably connected with the extrusion block.

Preferably, the lower end of the lower tray body is circumferentially provided with an extrusion inclined surface having the same inclination as the circumferential end surface of the extrusion block.

Preferably, the connecting plate is integrally formed with the tray body on the upper side.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the two disc bodies are hinged, so that the left end is fixed, after the two disc bodies are closed, the bolt is rotated to drive the extrusion block of the circular truncated cone shape to abut against the extrusion inclined plane on the disc body on the lower side, so that the two disc bodies are fixed, only one bolt needs to be fixed when the two disc bodies are fixed, and the time is saved;

2. when the connecting plate is opened, the bolt is rotated, the extrusion block is separated from the extrusion inclined plane, the disc body on the upper side can be turned, so that the rotating length is less, the time is shorter, the time is saved, and meanwhile, the bolt is always connected to the connecting plate, so that the connecting strength is ensured.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a front view of the present invention.

In the figure: the device comprises a plate body 1, a connecting pipe 11, a sealing washer 12, a connecting plate 2, a bolt 21, an extrusion block 22 and an extrusion inclined plane 23.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 2, the present invention provides a flange with convenient opening: the flange convenient to open comprises a plate body 1 and a connecting pipe 11 connected to the plate body 1, wherein the plate body 1 is divided into an upper plate and a lower plate, and a sealing gasket 12 is arranged between the two plate bodies 1.

The left ends of the two disc bodies 1 are hinged and connected, the right end of the disc body 1 at the upper side is fixed with a connecting plate 2 which is bent downwards into a right angle, the connecting plate 2 is connected with a screwing mechanism which is fixed by extruding the lower end surface of the disc body 1 at the lower side from one side, the screwing mechanism comprises a left bolt 21 which is in threaded connection with the connecting plate 2, and the left end of bolt 21 is installed and is appeared the extrusion piece 22 of round platform type left with the tip of the lower terminal surface circumference contact of the disk body 1 of downside, bolt 22 rotates, drive the disk body 1 of downside that extrudes piece 22, bolt 21 rotates with extrusion piece 22 and is connected, reduce the friction that brings when rotating, the lower extreme circumference of the disk body 1 of downside establishes into the extrusion inclined plane 23 with the circumference terminal surface gradient unanimity of extrusion piece 22, increase and the area of contact of extrusion piece 22, avoid the angular wear, connecting plate 2 and the disk body 1 integrated into one piece of upside, and is more durable, and the manufacturing is also convenient for.

The working principle is as follows: two disk body 1 are articulated to be connected, the left end just is fixed like this, close the back, rotate bolt 21, bolt 21 drives the extrusion piece 22 of round platform type and supports extrusion inclined plane 23 on the disk body 1 of downside, thereby it is fixed, when here is fixed, only need fixed bolt 21 can, the time is saved, when opening, rotate bolt 21, extrusion piece 22 breaks away from extrusion inclined plane 23, the disk body 1 of upside can overturn, rotatory length just so is less, the time is shorter, the time is saved, and simultaneously, bolt 21 is connected always on connecting plate 2, and the joint strength is guaranteed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
