[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0020] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0021] A pipe joint that is easy to install provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings. Example 1

[0022] Combination Figure 1-3 As shown, the utility model provides a pipe joint that is easy to install, including a splicing module 100, the splicing module 100 includes an outer tube 110, two flat openings 120 opened at the top and bottom of the outer tube 110, a pipe sleeve 130 detachably sleeved on the outside of the outer tube 110, two snap-on plates 140 movably embedded in the inner end of the outer tube 110, and a threaded pressing tube 150 threadedly connected to the pipe sleeve 130, and a slot suitable for snap-on connection of the snap-on plate 140 is opened on the pipe sleeve 130.

[0023] Furthermore, the inner cavity top and the inner cavity bottom of the tube sleeve 130 are both set as planes, and the two planes are respectively matched with the two flat openings 120. With this structural design, the tube sleeve 130 and the outer tube 110 are spliced, and the tube sleeve 130 will not move.

[0024] Furthermore, the interior of the threaded pressing tube 150 is composed of a threaded channel, a small channel and a large channel. The small channel is located between the threaded channel and the large channel, and the three are interconnected. The diameter of the small channel is equal to the diameter of the inner end of the outer tube 110. The tube sleeve 130 is located inside the threaded channel. This structural design ensures that the snap-on plate 140 can be tightened to prevent the snap-on plate 140 inserted into the slot from loosening. Example 2

[0025] Combination Figure 2-3 As shown, based on the first embodiment, the two snap-on plates 140 are laterally symmetrical about the horizontal center plane of the flat mouth 120, and the snap-on plates 140 are arranged in a U shape. With this layout design, the outer tube 110 and the tube sleeve 130 can be firmly connected. Example 3

[0026] Combination Figure 2-3 As shown, in the above embodiment, the snap-on plate 140 is made of an alloy material and fits with the inner wall of the threaded pressing tube 150. The snap-on plate 140 made of the alloy material has a high hardness and is not prone to breakage.

[0027] The working principle and use process of the utility model are as follows: before the device is assembled, each part is a separate individual, but the snap-on plate 140 is connected to the outer tube 110. Then when the user assembles the product, firstly, the snap-on plate 140 is horizontally turned, and then the tube sleeve 130 is sleeved on the inner end of the outer tube 110, and the flat mouth 120 cooperates with the plane to prevent the tube sleeve 130 from rotating. Then, the snap-on plate 140 is flipped into the slot, which further improves the connection firmness between the outer tube 110 and the tube sleeve 130. Then, the threaded pressing tube 150 is tightened to improve the stability of the snap-on plate 140 being inserted into the slot. Under multiple restrictions, the outer tube 110 and the threaded pressing tube 150 are firmly connected. The structure is simple and the installation is convenient.

[0028] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
