Abstract

(57) [Summary] [Purpose] To provide a plastic T-type joint that can be easily positioned and has excellent workability. [Structure] A rain gutter shape 4 having a substantially U-shaped cross section, a convex portion 3 protruding inwardly is provided on a U-shaped bottom portion in the middle in the longitudinal direction, and the convex portion 3 having the convex portion 3 is formed at a right angle to the outer peripheral surface of the U-shaped bottom portion. A plastic T-shaped joint 1 to which one end of a cylindrical tubular body 5 is connected.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plastic T-shaped joint.

[0002]

[Prior art]

 In the conventional plastic T-joint, the pipe 8 is inserted into the U-shaped portion 7a of the T-joint 7 as shown in FIG. 3 for explaining the use state diagram (assembly drawing) and for explaining the pipe connecting method. The pipe 9 was inserted and fixed in the cylindrical tubular body 7b. Also, after inserting the pipe 8, in order to prevent the T-shaped joint from moving forward and backward and to the left and right and to rotate the pipe 8 due to impact, and to fix the pipe 8 completely by the T-shaped joint 7, Adhesive was applied to (also to the insertion part).

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional plastic T-joint is a work that is difficult to position, and is performed using a jig or the like. In addition, the application of the adhesive has a drawback that it takes a long curing time and cannot be moved during that time, resulting in poor work efficiency. An object of the present invention is to provide a plastic T-shaped joint which can be easily positioned and has excellent workability.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has a U-shaped cross section having a U-shaped cross section, and a U-shaped bottom having a U-shaped bottom having a U-shaped bottom having a U-shaped bottom having a U-shaped bottom. A means is provided for connecting one end of the cylindrical tubular body to the outer peripheral surface of the portion at a right angle.

[0005]

【Example】

 An embodiment of the present invention will be described with reference to FIGS. The T-shaped joint of the present invention, as shown in FIGS. 1 and 2, has a rain gutter-shaped portion (hereinafter, referred to as a U-shaped portion) 4 having a substantially U-shaped cross section and a cylindrical tubular body connected at a right angle to the portion. Hereinafter, referred to as a cylindrical portion) 5. In the middle of the U-shaped portion 4 in the length direction, a convex portion 3 protruding from the U-shaped bottom portion to the inner surface is provided.

Then, the pipe 2 is inserted into the U-shaped portion 4 and the other pipe is inserted into the cylindrical portion 5 to be used as the T-shaped joint 1 (the usage is the same as in the case of FIG. 3). ). In order to fix the pipe 2, it is preferable that the U-shaped portion 4 has a shape in which both upper sides of the U-shape are rounded inward rather than the true U-shape. Further, in order to facilitate the positioning of the pipe 2 and prevent the pipe 2 from moving left and right or rotating, a hole 6 is formed in the pipe 2, and the hole 6 is used by being fitted into the convex portion 3. The T-shaped joint 1 of the present invention is made of plastic, and although the kind of plastic is not particularly limited, it is integrally molded to strengthen the connecting portion between the U-shaped portion 4 and the cylindrical portion 5. Is preferred.

[0007]

[Effect of device]

 According to the present invention, the positioning can be easily performed, the dimensional accuracy is improved, and the T-joint does not move even when an impact is applied. Furthermore, since the pipe can be securely fixed without using an adhesive, work efficiency is improved.
