The width of the outer circumferential surface is composed of the insertion end portion (12a) formed to gradually narrow.

Description

Device for connecting conners of rectangular pipes}

The present invention relates to a square pipe edge connector that can be assembled to interconnect the corner of the square pipe in three directions.

Conventionally, in connecting the square pipes 1 as shown in FIG. 1, the connection parts of the pipes are faced to each other, and then the parts are integrally connected and fixed by argon welding, and the predetermined hollow part 2 exposed to the outside is fixed. The cover is covered with a plastic injection molding or a metal plate cap 3.

Therefore, in the case of the conventional square pipe fixing structure, the difficulty and promptness of the work that needs to be argon welded to each joint of each square pipe (1) and the separate grinding treatment of the welding spot is required as well as the welding failure Separate caps (3) to cover the hollows (2), which are necessarily generated due to the connection structure of the square pipes, with the risk of breakage of the joints of the square pipes and the risk of safety accidents due to welding and waste of materials. There were a number of problems, such as the need.

The present invention has been devised to solve such problems in the related art, and an object of the present invention is to quickly and easily fix a square pipe corner connection in three directions, but does not require a separate welding or cap for a hollow cover. To provide pipe edge connectors.

Features of the square pipe corner connector according to the present invention for achieving the above object, in connecting and fixing the known square pipe corner, the connector body for connecting and fixing the corner of the square pipe corner of the square pipe The connecting end of the rectangular shape for fixing the respective connection in three directions is formed integrally projecting integrally and at the same time the insertion end end formed with the connecting support piece to gradually narrow the width of the outer peripheral surface to induce the insertion of the square pipe It is at the point provided with.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail as follows.

Figure 2 is a perspective view showing the structure of the square pipe corner connector according to the present invention, the corner connector according to the present invention is configured to enable the connection of the square pipe (1) in three directions at the same time.

As the connector main body 10, the connecting support pieces 12 having the outer circumferential surface of the same shape as the square pipe 1 are integrally protruded integrally by a predetermined length so as to connect and fix the corners of the square pipe 1 in three directions, respectively. In this case, the stepped portion of the connection support piece 12 is formed to be equal to the thickness of the square pipe 1, so that the outer circumferential surface of the connector body 10 and the square pipe 1 inserted into the connection support piece 12 are formed. The outer peripheral surface is to maintain the same horizontal plane.

In addition, the connecting support pieces 12 are formed with insertion end portions 12a for easily inducing the initial inflow of the square pipe 1, which is very preferably formed so that its width gradually narrows inwardly. .

On the other hand, the connector body 10 according to the present invention is injection molded into a metal (aluminum) or high-strength plastic in consideration of the size of the square pipe (1), the center of each connection support piece 12 In order to save material, the hollow state is formed to be opened toward the insertion end 12a.

The square pipe corner connector according to the present invention configured as described above is a square pipe constituting three-way corners when forming a predetermined frame (for example, a pan die for baking) using the square pipe 1 as shown in FIG. When each end of 1) is pressed together to the connecting support piece 12 formed by the connector body 10, respectively, the three-way corners are firmly connected and fixed, wherein the square pipe 1 is the connecting support piece 12 The insertion end of the connector 12a is very easy to insert, and the square pipe 1 is connected to the main body of the connector as shown in FIG. The same horizontal surface is maintained as the outer circumferential surface of 10), and the assembling appearance is very beautiful. Especially, since each hollow part of the square pipe 1 is naturally covered by the assembly of the connector body 10, a separate cover as in the prior art It is not required capability.

In addition, in the case of the present invention, since the length of the square pipe 1 is inserted only to the stepped portion of the connection support piece 12 at least, the width of the connector body 10 which functions as a cover is omitted so that the length of the square pipe material You will also have the benefit of saving money.

And if you want to remove the square pipe (1) constituting the frame, since the pipe is forcibly fitted without a separate fastening means to the connecting support piece 12 of the connector body 10, simply remove it from there. Since the inner pipe is easy to separate from the connection fixing method by conventional welding, the reuse rate can be increased since the separation of the square pipe 1 can be easily performed, and in particular, it can be removed without damaging the square pipe.

According to the present invention as described above by fixing the corners of the square pipe connected to each other integrally by using a separate connector rather than the conventional welding method, each corner of the square pipe is very quick and easy to have an assembly appearance beautiful effect will be.

Although the present invention has been described with reference to the accompanying drawings, many modifications and changes may be made without departing from the scope of the following claims.

Claims (1)

In connecting and fixing the corner of a known square pipe (1), The connector body 10 for connecting and fixing the corners of the square pipe 1 is integrally integrally connected with a square support piece 12 for fixing the corners of the square pipe 1 in three directions. Square pipe corner connector characterized in that the connection support piece 12 is provided with an insertion end portion 12a formed to gradually narrow the width of the outer peripheral surface to guide the insertion of the square pipe (1) at the same time .
