[0002] The connection between tubular components by a pipe joint is a conventional connection structure, and the connection between the existing pipe joint and the tubular component is usually completed in a threaded manner. The existing threaded connection method has the advantages of tight and reliable connection.

[0003] In the prior art, tubular components are usually connected to the water supply pipe by a tail pipe joint with a threaded structure. However, when the threaded tail pipe joint and the water supply pipe are disassembled, scale is easily accumulated between the grooves of the threaded structure, which makes it inconvenient to disassemble and install the threaded structure of the tail pipe joint and the water supply pipe after use, and is not conducive to the replacement and cleaning of the tubular component at the water supply pipe. To this end, a quick connection mechanism between a pipe joint and a pipe body is proposed. Utility Model Content

When the insert pipe needs to be disassembled, the protruding column can be pressed into the tail pipe, which is convenient for the insert pipe to be quickly removed from the tail pipe, and convenient for disassembling and replacing the tubular component with the tail pipe at the water supply pipe, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figures 1-3 As shown, a quick connection mechanism between a pipe joint and a pipe body comprises a tubular component 1, a tail pipe 2 and a water supply pipe 3, and also comprises an internal connection mechanism 4, wherein the internal connection mechanism 4 comprises a plug 5, a boss 6, a rib connection portion 10 and a threaded tail pipe 11. The rear part of the pipe body of the tubular component 1 is integrally formed with a tail pipe 2, and the pipe body surface of the tail pipe 2 is symmetrically provided with fixed holes 8 for clamping the boss 6. The bosses 6 are symmetrically raised on the outer pipe wall surface of the plug 5, and the surface of the plug 5 between the bosses 6 is symmetrically provided with V-shaped ports 9, and rib connection portions 10 are fixed between the cavity walls of the V-shaped ports 9. A threaded tail pipe 11 is integrally formed on the rear pipe body of the plug 5 away from the V-shaped ports 9, a threaded hole 12 is provided at the inner pipe cavity of the water supply pipe 3, and the threaded tail pipe 11 is screwed into the threaded hole 12, and a sealing ring 13 is bonded to the outer sleeve of the plug 5 between the V-shaped port 9 and the threaded tail pipe 11.

[0026] The largest opening of the V-shaped opening 9 is arranged on both sides of the opening of the cannula 5, and the tube body of the cannula 5 is integrally formed with a rib-connecting portion 10 fixed between the cavity walls of the V-shaped opening 9;

[0027] By adopting the above technical solution, after the V-shaped butt joint 9 is set at the tube mouth of the cannula 5, the tube body of the cannula 5 can press and shrink the tube mouth in opposite directions, so that the boss 6 can be removed downward from the fixed hole 8. After the boss 6 and the cannula 5 are pulled out from the tail pipe 2, the cannula 5 can elastically recover.

[0028] The height of the protruding column 6 is smaller than the depth of the fixed hole 8.

[0029] By adopting the above technical solution, after the shorter convex post 6 is inserted into the fixed hole 8, the convex post 6 can easily come out downward from the fixed hole 8 after the insertion tube 5 is stressed and shrunk.

[0030] Wherein, a corner slope block 7 protrudes from the top of the convex post 6, and the corner slope block 7 abuts against the vertical hole wall of the fixed hole 8;

[0031] By adopting the above technical solution, the convex post 6 can be stuck in the fixed hole 8 with the corner slope block 7, increasing the top contact area between the convex post 6 and the fixed hole 8.

[0032] Wherein, three groups of sealing rings 13 are arranged and bonded on the outer tube wall surface of the insertion tube 5;

[0033] By adopting the above technical solution, having more sealing rings 13 outside the insertion tube 5 can improve the insertion sealing performance between the insertion tube 5 and the tail connecting tube 2.

[0034] Wherein, the depth of the threaded hole wall in the water supply pipe 3 is the same as the tube body length of the threaded tail tube 11;

[0035] By adopting the above technical solution, the water supply pipe 3 can be adaptively screwed and connected to the threaded tail tube 11 with the threaded hole 12.

[0036] It should be noted that the present utility model is a quick connection mechanism for a pipe joint and a pipe body. A fixed hole 8 is provided at the tail connecting tube 2 of the tubular member 1, and a threaded hole 12 is provided at the water supply pipe 3. Together with the inner connection mechanism 4, a connection mechanism is formed between the tail connecting tube 2 of the tubular member 1 and the water supply pipe 3. When the tail connecting tube 2 of the tubular member 1 needs to be connected to the water supply pipe 3, the threaded tail tube 11 of the inner connection mechanism 4 can be screwed and installed at the threaded hole 12 of the water supply pipe 3 for installation. Then, the insertion tube 5 outside the threaded tail tube 11 can be inserted into the tail connecting tube 2. When the insertion tube 5 with the convex post 6 enters the tail connecting tube 2, the insertion tube 5 presses the rib connecting part 10 to elastically contract at the V-shaped butt joint 9, so that the convex post 6 and the insertion tube 5 can smoothly enter the tail connecting tube 2. When the convex post 6 enters the fixed hole 8, after the insertion tube 5 elastically restores, the convex post 6 can push the corner slope block 7 upward to abut against the fixed hole 8. At this time, the insertion tube 5 completes a quick connection between the tail connecting tube 2 and the water supply pipe 3. When the insertion tube 5 needs to be removed from the tail connecting tube 2, only need to insert a metal rod into the fixed hole 8 and press the metal rod oppositely, so that the convex post 6 and the corner slope block 7 can slide into the tail connecting tube 2 from the fixed hole 8, and then the insertion tube 5 can be directly pulled out and disassembled from the tail connecting tube 2. At this time, a new tubular member 1 and tail connecting tube 2 provided with a fixed hole 8 can be taken and installed at the water supply pipe 3 according to the above steps.
