Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0023] Reference Figure 1 - Figure 5 This utility model discloses a high-strength anti-fall-off plum blossom tube splicing assembly, including an insertion connector 1 and a tube body 2. The outer diameter of the insertion connector 1 is the same as the inner diameter of the tube body 2. The middle of the outer side wall of the insertion connector 1 is raised to form an annular part 3 with the same outer diameter as the tube body 2. Both sides of the annular part 3 are provided with sealing rings 4 that contact the tube body 2. Both sides of the insertion connector 1 are provided with sealing components 5 that contact the inner wall of the tube body 2.

[0024] In this embodiment, when in use, one side of the insertion connector 1 is inserted into one of the tubes 2, and then the other side of the insertion connector 1 is inserted into another tube 2 to complete the connection of the plum blossom tube.

[0025] Since the pipe bodies 2 of two adjacent plum blossom pipes are connected by the insertion joint 1, a gap will be generated between the insertion joint 1 and the pipe body 2. When the plum blossom pipe is buried underground, water will seep into the gap between the pipe body 2 and the insertion joint 1, affecting the safety of the plum blossom pipe.

[0026] Therefore, observe Figure 3 It can be observed that an annular portion 3, with the same outer diameter as the tube body 2, is provided in the middle of the insertion connector 1. Then, looking... Figure 1 It can be seen that a sealing ring 4 is provided on the side wall of the annular part 3. When the tube body 2 is inserted into the insertion connector 1, the sealing ring 4 is squeezed by the annular part 3 to reduce the gap between the tube body 2 and the insertion connector 1, thereby improving the sealing performance of the plum blossom tube and preventing water from seeping into the plum blossom tube through the installation gap and affecting the use of the plum blossom tube.

[0027] observe Figure 1It can also be found that, besides the annular part 3 and the sealing ring 4 arranged on the outer side wall of the insertion joint 1, the sealing assembly 5 is arranged, which can reduce the gap between the pipe body 2 and the insertion joint 1 when the pipe body 2 is inserted into the insertion joint 1, and can be used to further improve the sealing performance of the plum blossom pipe, thereby effectively avoiding water seepage, and effectively reducing the maintenance frequency of the plum blossom pipe, thereby reducing the use cost of the plum blossom pipe.

[0028] In further preferable embodiments of the utility model, as shown in Figure 4 and Figure 5 The sealing assembly 5 is composed of a sealing air bag 51 and an auxiliary pressing block 52, the outer side wall of the insertion joint 1 is provided with an annular groove 6 and is sleeved with the sealing air bag 51, at least two groups of auxiliary pressing blocks 52 are arranged in the annular array of the outer side wall of the insertion joint 1 between the annular groove 6 and the annular part 3, and the inner side wall of the pipe body 2 is provided with an insertion slot 7 for inserting the auxiliary pressing block 52.

[0029] In the embodiment, due to the existence of the mounting tolerance of the parts, a gap will be generated after the insertion joint 1 is inserted into the pipe body 2, thereby causing the sealing ring 4 to be unable to guarantee the sealing effect after being aged in a humid environment for a long time, and water will seep into the installation gap between the insertion joint 1 and the pipe body 2, then enter the plum blossom pipe along the gap, and affect the use of the cable inside the plum blossom pipe.

[0030] Therefore, as shown in Figure 4 and Figure 5 It can be found that the sealing air bag 51 is arranged on the outer side wall of the insertion joint 1, and the gap between the inner wall of the insertion joint 1 and the pipe body 2 is reduced by the sealing air bag 51, thereby further improving the protection performance of the plum blossom pipe on the cable.

[0031] Since the sealing air bag 51 is an elastic component, when the insertion joint 1 is rotated after being inserted into the pipe body 2, the part of the sealing air bag 51 in contact with the inner wall of the pipe body 2 will be twisted and deformed due to the friction and traction of the inner wall of the pipe body 2, thereby causing wrinkles in the deformed area and affecting the sealing effect, therefore, the auxiliary pressing block 52 is further arranged on the outer side wall of the insertion joint 1, and the insertion slot 7 is arranged on the inner side wall of the pipe body 2, so that the relative rotation between the insertion joint 1 and the pipe body 2 is prohibited by the auxiliary pressing block 52 when the pipe body 2 is inserted into the insertion joint 1, thereby effectively guaranteeing the sealing effect of the sealing air bag 51.

[0032] In further preferable embodiments of the utility model, as shown in Figure 1 and Figure 3 The side of the auxiliary pressing block 52 close to the annular part 3 and the annular part 3 leave a gap to form an installation slot for clamping the sealing ring 4.

[0033] In the embodiment, the outer side wall of the insertion joint 1 is provided with the auxiliary pressing block 52, which will cause the sealing ring 4 to be blocked by the auxiliary pressing block 52 and deformed, thereby affecting the normal use of the sealing ring 4. Figure 3 It can be found that the gap is left between the auxiliary pressing block 52 and the annular part 3, so that the sealing ring 4 can be clamped in the gap when being pressed, thereby preventing the sealing ring 4 from being affected by the auxiliary pressing block 52 after being installed and ensuring the sealing performance.

[0034] Meanwhile, the gap between the auxiliary pressing block 52 and the annular part 3 can form an installation groove for positioning the sealing ring 4, so that the sealing ring 4 will not be detached after being installed, and the sealing ring 4 will not be shaken or deviated when the insertion joint 1 is inserted into the pipe body 2, thereby making the insertion of the insertion joint 1 into the pipe body 2 more simple.

[0035] In the further preferable embodiment of the utility model, as shown in Figure 5 The side of the auxiliary pressing block 52 close to the sealing air bag 51 is provided with an extension 8, the extension 8 is located at the top of the sealing air bag 51 and contacts the sealing air bag 51, and the length of the extension 8 is less than the length of the sealing air bag 51.

[0036] In the embodiment, the extension 8 is arranged on the auxiliary pressing block 52 and contacts the outer side wall of the sealing air bag 51, so that the sealing air bag 51 is pressed and deformed by the extension 8 when the insertion joint 1 is inserted into the pipe body 2, thereby causing the region of the sealing air bag 51 under pressure to expand and further reducing the gap between the sealing air bag 51 and the inner wall of the pipe body 2.

[0037] Since the sealing air bag 51 is deformed under pressure, the gap between the recesses in the pipe body 2 will increase, thereby affecting the sealing performance. Figure 5 It can be found that the length of the extension 8 is less than the length of the sealing air bag 51, so that the sealing air bag 51 can still be in full contact with the inner wall of the pipe body 2 when the extension 8 presses the sealing air bag 51, thereby ensuring the sealing performance of the sealing air bag 51.

[0038] In the further preferable embodiment of the utility model, as shown in Figure 5 The inner wall of the insertion slot 7 is provided with a pressing portion 9, and the top of the extension 8 is provided with a pressing groove 10 for the pressing portion 9.

[0039] In the embodiment, the extension part 8 is pressed to extrude the sealing air bag 51, thereby enhancing the sealing performance of the sealing air bag 51. The pressing groove 10 is arranged on the outer wall of the extension part 8 and cooperates with the extruding part 9, so that the extruding part 9 can easily enter the upper part of the extension part 8 when the plug-in connector 1 is inserted into the pipe body 2, and the extruding part 9 can better extrude the extension part 8.

[0040] In the further preferable embodiment of the utility model, as shown in Figure 1 and Figure 2 the outer wall of the annular part 3 is fixedly connected with a positioning flange 11, and the pipe opening of the pipe body 2 is fixedly connected with a connecting flange 12 connected with the positioning flange 11.

[0041] In the embodiment, the plug-in connector 1 and the pipe body 2 are connected by simple insertion, which affects the next compression when the plum blossom pipe is disassembled and repaired, thereby weakening the sealing performance of the plum blossom pipe. Therefore, the positioning flange 11 is arranged on the annular part 3, and the connecting flange 12 connected with the positioning flange 11 is arranged on the opening of the pipe body 2, so that the pipe body 2 and the plug-in connector 1 are connected by bolt fastening, thereby ensuring the installation firmness of the plum blossom pipe.

[0042] The embodiments of the specific embodiment are preferable embodiments of the utility model, and do not limit the protection scope of the utility model, so that: equivalent changes made according to the structure, shape and principle of the utility model should be covered in the protection scope of the utility model.
