DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0028] Example 1

[0029] In this embodiment, if Figure 1-Figure 7 As shown, a high-sealability bellows injection joint structure includes an injection joint 101 and a corrugated pipe 102, and also includes a locking mechanism 200. The locking mechanism 200 is arranged on one side of the injection joint 101 and is used to connect the injection joint 101 and the corrugated pipe 102. Before the high-sealability bellows injection joint structure is used, the structure is first checked to see if it can be used normally, and then the locking mechanism 200 is adjusted. After the fixed pipe 201 is aligned with the connecting pipe 202, the outer ring block 210 or the injection joint 101 is rotated to put the structure into a ready-to-use state.

[0030] The locking mechanism 200 includes a fixed tube 201 fixedly connected to the injection molded joint 101, and an external threaded groove is provided on the outer surface of the fixed tube 201. A connecting tube 202 is fixedly installed on the side of the corrugated pipe 102 close to the injection molded joint 101, and a movable sealing tube 203 is slidingly provided inside the connecting tube 202. The inner diameter of the connecting tube 202 is adapted to the outer diameter of the movable sealing tube 203. The movable sealing tube 203 is connected to the fixed tube 201 through a clamping assembly. A slide groove 204 is provided on the surface of the connecting tube 202, and a sliding assembly for driving the movable sealing tube 203 to move is provided inside the slide groove 204. Through the sliding assembly, the movable sealing tube 203 can be driven to move, thereby completing the engagement between the protrusion 206 and the groove 205, thereby improving the sealing effect of the connection.

[0031] Among them Figure 2-Figure 4 As shown, the clamping assembly includes a groove 205 arranged inside the fixed tube 201, and a number of protrusions 206 are evenly arranged inside the movable sealing tube 203. The movable sealing tube 203 and the protrusion 206 are an integrated structure. The shape and size of the groove 205 are adapted to the protrusion 206. The inner wall of the groove 205 fits with the movable sealing tube 203. Through the groove 205, the movable sealing tube 203 can complete the clamping operation with the fixed tube 201, and can play a limiting role on the outer ring block 210 to prevent the outer ring block 210 from rotating loose. An elastic sealing gasket is provided on the inner wall of the groove 205 to improve the stability and sealing of the connection, thereby effectively extending the service life of the structure.

[0032] Among them Figure 3-Figure 7 As shown, the sliding assembly includes a slider 207 fixedly arranged at the upper end of the movable sealing tube 203. The size of the slider 207 is adapted to the slide groove 204. The slider 207 is slidably connected to the slide groove 204. A positioning block 208 is provided on one side of the slide groove 204. The slider 207 is connected to the positioning block 208 by a spring. The spring can push the movable sealing tube 203 to move along the direction of the slide groove 204, thereby facilitating the matching of the movable sealing tube 203 with the groove 205. When the corrugated pipe 102 needs to be disassembled and separated from the injection molded joint 101, the slider 207 is pulled toward the side of the positioning block 208 through the sliding assembly, so that the movable sealing tube 203 is separated from the groove 205, and then the outer ring block 210 is rotated to realize the separation operation of the corrugated pipe 102 and the injection molded joint 101. A protective plate 209 is also provided on the outside of the slider 207 to reduce the probability of damage to the spring, slider 207 and positioning block 208.

[0033] Among them Figure 3 As shown, an outer ring block 210 is fixedly provided on one side of the connecting pipe 202 close to the injection molded connector 101. The outer ring block 210 is sleeved on the outside of the fixed pipe 201. The outer ring block 210 is threadedly connected to the fixed pipe 201, so that the injection molded connector 101 and the corrugated pipe 102 are firmly connected, and it is also convenient for disassembly and installation.

[0034] Among them Figure 5 As shown, a rubber sealing pad is provided on the outer side of the movable sealing tube 203 , and the rubber sealing pad contacts the inner wall of the connecting tube 202 , thereby increasing the overall sealing effect of the structure.

[0035] Among them Figure 5 As shown, the outer ring block 210 and the slider 207 are connected by bolts to fix the position of the movable sealing tube 203 and prevent the protrusion 206 from being separated from the groove 205, resulting in poor sealing effect.

[0036] Among them Figure 1 and Figure 3As shown, several anti-sliding blocks are fixedly installed on the outside of the outer ring block 210, and the anti-sliding blocks are evenly distributed on the outer surface of the outer ring block 210, so as to facilitate the user to hold the outer ring block 210, increase the contact area between the user's hand, and then fix the position of the outer ring block 210 and the fixed tube 201, thereby realizing the connection function of the injection molded joint 101 and the corrugated pipe 102.

[0037] Example 2

[0038] The difference from Example 1 is that Figure 8 and Figure 9 As shown, the locking mechanism 200 also includes an articulated seat 211 symmetrically mounted on the surface of the outer ring block 210, and a limiting rod 212 is hinged on the articulated seat 211. The other end of the limiting rod 212 is movably connected to a sealing cover 213, and the lower end of the sealing cover 213 is fixedly provided with a buckle 214. The buckle 214 and the buckle groove 215 are common buckle structures in this field, which are prior art. The injection molded joint 101 is provided with a buckle groove 215 that cooperates with the sealing buckle 214, further improving the connection tightness between the corrugated pipe 102 and the injection molded joint 101, effectively preventing the injection molded joint 101 from showing signs of rotation and loosening, and has good practicality.

[0039] When in use, first loosen the bolts at the slider 207 to separate the outer ring block 210 from the slider 207, pull the movable sealing tube 203 toward the side of the positioning block 208 through the slider 207, and then put the outer ring block 210 on the outside of the fixed tube 201. With the cooperation of the thread, the connection between the outer ring block 210 and the fixed tube 201 is firm, and then loosen the slider 207, so that the movable sealing tube 203 can drive several protrusions 206 to snap into the inside of the groove 205, and the movable sealing tube 203 and the elastic sealing gasket inside the groove 205 squeeze each other, thereby filling the gap between the groove 205 and the movable sealing tube 203, achieving a better sealing effect and effectively preventing the outer ring block 210 from rotating loose.

[0040] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
