Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe fittings, in particular to a stainless steel pipe fitting with a plug-in joint. Background Art

[0002] Stainless steel pipe fittings are a type of pipe fittings. They are made of stainless steel, so they are called stainless steel pipe fittings. They include: stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel reducers, stainless steel pipe caps, etc. According to the connection method, they can be divided into four categories: socket-type stainless steel pipe fittings, threaded stainless steel pipe fittings, flanged stainless steel pipe fittings and welded stainless steel pipe fittings. Most of the existing stainless steel pipe fittings are connected by flange connection, welding and other methods. Since these connection methods require the use of tools to assist in multiple operations, they are very cumbersome and have low efficiency in connecting pipe fittings. In order to improve the connection efficiency of pipe fittings, stainless steel pipe fittings with plug-in joints will be used. Through the connection of plug-in joints, stainless steel pipe fittings can be connected more quickly, thereby improving the connection and installation efficiency of stainless steel pipe fittings.

[0003] For example, the patent number CN219692519U discloses a stainless steel pipe fitting with a plug-in joint, which includes a stainless steel pipe fitting body, a plug fixedly installed at one end of the stainless steel pipe fitting body, a threaded block fixedly arranged on the outside of the plug, a joint body fixedly installed at the other end of the stainless steel pipe fitting body, a pair of through holes opened on the outer wall of the joint body, connecting rods inserted and installed inside the pair of through holes, a pair of connecting rods fixedly installed at one end away from each other, and the other end of the connecting rod extends to the inside of the joint body. When connecting the stainless steel pipe fitting body, by inserting the plug into the inside of the joint body and fixing the plug inside the joint body with the fixing block, it is convenient for the staff to connect and install the stainless steel pipe fitting body, thereby improving the efficiency of the staff when connecting the stainless steel pipe fitting body and increasing the convenience of the structure.

[0004] However, the stainless steel pipe fittings in the above technology still have the following problems:

[0005] When connecting two pipes to each other, the two fixing blocks need to be pulled outward to connect them with the threaded blocks on the plug. The actual installation and connection is inconvenient, and whether the fixing blocks and the threaded blocks are completely connected cannot be observed because they are inside the pipes. After being connected to each other, they may slip and loosen, and the stability of the connection is poor. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1 - Figure 3 A stainless steel pipe fitting with a plug-in joint comprises a pipe body 1, wherein two ends of the pipe body 1 are respectively connected with a connecting ring 2 and a plurality of connecting rods 3, the connecting ring 2 is sleeved on one end of the pipe body 1, and is fixedly connected to the outer wall of one end of the pipe body 1, the plurality of connecting rods 3 are fixedly connected to the outer wall of the pipe body 1 away from the connecting ring 2, and the plurality of connecting rods 3 are evenly distributed in a ring shape, the plurality of connecting rods 3 are away from one end of the pipe body 1, and a connecting groove 301 is opened on the side close to the pipe body 1, and the plurality of connecting grooves 301 are matched with the connecting ring 2.

[0022] like Figure 1 - Figure 3 As shown, the stainless steel pipe fitting with a plug-in joint in the utility model is similar to the existing stainless steel pipe fitting with a plug-in joint, such as the stainless steel pipe fitting with a plug-in joint disclosed in the patent with publication number CN219692519U. The main improvement of the utility model is that the user can connect and fix two stainless steel pipe fittings more quickly, such as Figures 1 to 3 As shown, when the stainless steel pipe fitting with a plug-in joint in the utility model is in use, one end of the pipe fitting body 1 close to the connecting ring 2 is close to one end of the connecting rod 3 on the other pipe fitting body 1, and is inserted into the multiple connecting rods 3. When the connecting ring 2 contacts the multiple connecting rods 3, the two pipe fitting bodies 1 continue to be squeezed against each other, so that the connecting ring 2 squeezes and bends the multiple connecting rods 3 outward, and then the connecting ring 2 continues to move into the multiple connecting rods 3. When the connecting ring 2 contacts the connecting grooves 301 on the multiple connecting rods 3, the multiple connecting rods 3 return inward, thereby clamping the connecting ring 2 in the connecting grooves 301 of the multiple connecting rods 3. At this time, the two stainless steel pipe fitting bodies 1 complete the purpose of being connected and fixed to each other, and in the design, when the connecting ring 2 is clamped in the connecting groove 301, the two pipe fitting bodies 1 are against each other, thereby preventing the connecting ring 2 from shaking in the connecting groove 301, ensuring the connection stability between the two pipe fitting bodies 1, wherein the connecting rod 3 is a hook-shaped rod with a certain bendable and rebound effect.

[0023] like Figure 1 - Figure 3As shown, the number of the plurality of connecting rods 3 is not less than three. The plurality of connecting rods 3 shall not be less than three and are evenly distributed on the outside of the pipe body 1, so as to ensure that after the plurality of connecting rods 3 are connected to the connecting ring 2, the plurality of connecting rods 3 cooperate with each other to wrap the pipe body 1 inside, so that the connection between the pipe bodies 1 will not be loose.

[0024] like Figure 1 - Figure 3 As shown, the inner wall of the pipe body 1 close to the connecting ring 2 is fixedly connected with an easy insertion tube 4, and the end of the easy insertion tube 4 away from the pipe body 1 is of a conical design. When one end of the connecting ring 2 of the pipe body 1 is inserted into another pipe body 1, the pipe body 1 can be more conveniently inserted between multiple connecting rods 3 of another pipe body 1 through the easy insertion tube 4.

[0025] like Figure 1 - Figure 3 As shown, the outer side of the connecting ring 2 away from the end of the connecting rod 3 is provided with an inclined surface. The outer side of the end of the connecting ring 2 away from the connecting rod 3 on the same pipe body 1 is provided with an inclined surface, and when the connecting ring 2 is close to the connecting rod 3 of another pipe body 1, the inclined surface contacts the end of the connecting rod 3, so that the multiple connecting rods 3 can be more easily pressed and bent outward through the inclined surface, so that the connecting ring 2 can be smoothly inserted into the connecting grooves 301 of the multiple connecting rods 3.

[0026] like Figure 1 - Figure 3 As shown, the inner sides of the ends of the connecting rods 3 away from the pipe body 1 are all provided with inclined surfaces. The inner sides of the ends of the connecting rods 3 are provided with inclined surfaces, and when the connecting ring 2 contacts the connecting rods 3, the inclined surfaces of the connecting rods 3 contact the connecting ring 2, and the connecting rods 3 can be squeezed outwards more easily through the connecting ring 2.

[0027] like Figure 1 - Figure 3 As shown, the outer wall of the pipe body 1 is sleeved and slidably connected with an easy-detachable ring 5, which is located between the connecting ring 2 and a plurality of connecting rods 3. When two mutually connected pipe bodies 1 need to be disassembled from each other, the easy-detachable ring 5 can be slid on the pipe body 1, and the easy-detachable ring 5 is moved close to the connecting ring 2, and a plurality of connecting rods 3 clamped on the connecting ring 2 are pressed and pushed outward, and the connecting rods 3 are pressed and bent outward, so that the connecting groove 301 is separated from the connecting ring 2, and then the two pipe bodies 1 can be smoothly disassembled from each other.

[0028] like Figure 1 - Figure 3As shown, the outer side of the easily detachable ring 5 close to one end of the connecting ring 2 is provided with an inclined surface, and the wall thickness of the easily detachable ring 5 is not less than the wall thickness of the connecting ring 2. The inclined surface is provided on the outer side of the easily detachable ring 5 close to one end of the connecting ring 2, and the inclined surface contacts the inner side of the connecting rod 3, so that the easily detachable ring 5 can more easily press and bend the connecting rod 3 stuck on the connecting ring 2 outward, so that the two pipe fitting bodies 1 can be separated from each other smoothly. At the same time, the wall thickness of the easily detachable ring 5 is set to be greater than the wall thickness of the connecting ring 2, so that when the easily detachable ring 5 can press and bend multiple connecting rods 3 outward, the connecting groove 301 of the connecting rod 3 can be separated from the connecting ring 2 smoothly, so as to complete the separation operation of the two pipe fitting bodies 1.

[0029] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
