[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1

[0028] Reference Figure 1-Figure 2 , which is the first embodiment of the utility model, and this embodiment provides a cable intermediate joint sealing structure. The cable intermediate joint sealing structure includes a main body component 100 and a shunt component 200. Through the cooperation of the two, the protection measures are improved and the sealing effect is increased, thereby better and more effectively protecting the safety and reliability of the intermediate joint, which is beneficial to the stable transmission of equipment signals and prolonging the service life.

[0029] Specifically, the main component 100 includes a shell 101, a partition 102, a connecting pipe 103, a glue injection pipe 104 and a glue injection port 105. The partition 102 is fixed in the shell 101. An outer chamber 101a is opened between the partition 102 and the inner wall of the shell 101. An inner chamber 101b is opened between the two partitions 102. The connecting pipe 103 is fixed in the partition 102. The glue injection pipe 104 is fixed at one end of the connecting pipe 103. The glue injection port 105 is fixed at the other end of the glue injection pipe 104.

[0030] There are two of the partition 102, the connecting pipe 103, the glue injection pipe 104 and the glue injection port 105. The glue injection pipe 104 is arc-shaped, which is conducive to the rapid circulation of glue inside the glue injection pipe 104 and improves the fluidity of the glue injection. The glue injection port 105 is conical, which is convenient for adding glue and improves the efficiency of glue injection. When the two glue injection ports 105 are injected with glue at the same time, the glue will flow into the inner chamber 101b along the glue injection pipe 104 and the connecting pipe 103. As the glue in the inner chamber 101b continues to increase, when the glue injection reaches a certain liquid level, the glue injection into the inner chamber 101b will be stopped, and the glue injection into the outer chamber 101a will be started at the same time, until the glue injection of the outer chamber 101a is completed, the glue injection is stopped, and the glue is waited for to solidify. In this way, the water flow pressure and water permeability in the outer chamber 101a are sharply reduced, thereby improving the waterproof and anti-permeability of the inner chamber 101b, enhancing the sealing ability, avoiding equipment damage and extending the service life.

[0031] Specifically, the diverter assembly 200 is disposed in the connecting tube 103 , and includes a falling piece 201 , a sliding piece 202 and a blocking piece 203 . The falling piece 201 is located in the connecting tube 103 , the sliding piece 202 is disposed on one side of the falling piece 201 , and the blocking piece 203 is disposed below the connecting tube 103 .

[0032] There are two falling pieces 201, sliding pieces 202 and flow-blocking pieces 203, all of which are located in the connecting tube 103. By setting the flow-blocking piece 203 and the sliding piece 202, the flow-blocking piece 203 can block the flow and separate the falling piece 201 at the same time. When the flow-blocking piece 203 is continuously moved upward by the buoyancy of the liquid surface, the flow-blocking piece 203 forms a blocking effect in the connecting tube 103, and the injection of glue is stopped. At the same time, when the flow-blocking piece 203 reaches a certain position, it will squeeze the sliding piece 202, causing the sliding piece 202 to move, thereby pushing the falling piece 201 to separate and start the injection of glue. The operation is convenient in completing the blocking and separation effects, and it can be completed without the aid of additional tools.

[0033] Example 2

[0034] Reference Figure 3-Figure 5 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0035] Specifically, the falling part 201 includes a baffle 201a, a hanging column 201b and a fixed column 201c. A drop hole 201d is opened on the connecting tube 103. The baffle 201a is located in the drop hole 201d. One end of the hanging column 201b is fixed to the baffle 201a. The fixed column 201c is fixed to the inner top wall of the connecting tube 103.

[0036] By setting the hanging column 201b and the fixing column 201c, the baffle 201a can be suspended in the blanking hole 201d to block the blanking hole 201d, thereby preventing the glue in the connecting pipe 103 from being injected into the outer chamber 101a.

[0037] Specifically, the drop member 201 further includes a connecting pin 201f, which is located on one side of the fixed column 201c. The hanging column 201b and the fixed column 201c are both provided with a pin hole 201-1, and the connecting pin 201f is engaged with the pin hole 201-1.

[0038] The connecting pin 201f is U-shaped, and both ends are inserted into the pin hole 201-1. Through the cooperation of the connecting pin 201f and the pin hole 201-1, the fixed column 201c can support the hanging column 201b, thereby preventing the hanging column 201b and the baffle 201a from falling and causing the blanking hole 201d to open prematurely.

[0039] Specifically, the sliding member 202 includes a sliding block 202a and a push plate 202b. The sliding block 202a is located in the connecting tube 103, and the push plate 202b is fixed to one end of the sliding block 202a.

[0040] One end of the sliding block 202a is inclined, and when it is squeezed, it will be displaced, so that the sliding block 202a drives the push plate 202b to move, and the push plate 202b pushes open the connecting pin 201f, releasing the restriction between the connecting pin 201f and the pin hole 201-1, separating the two, so that the hanging column 201b and the baffle 201a fall together, thereby opening the drop hole for injecting glue into the external chamber 101a.

[0041] Specifically, the sliding member 202 includes a fixed block 202c and a roller 202d. The fixed block 202c is fixed in the connecting tube 103, and both ends of the roller 202d are respectively fixed to the two fixed blocks 202c.

[0042] The arrangement of the fixed block 202c and the roller 202d can support the sliding block 202a, reduce the sliding resistance, make the sliding block 202a more firm and reliable, and prevent the sliding block 202a from falling.

[0043] Specifically, the sliding member 202 further includes a limiting plate 202e, which is fixed to the inner top wall of the connecting tube 103 and is located at one end of the sliding block 202a.

[0044] During the glue injection process, the sliding block 202a will move when subjected to liquid pressure, and the limiting plate 202e can better limit the position of the sliding block 202a, thereby preventing the sliding block 202a from slipping due to the liquid pressure.

[0045] Example 3

[0046] Reference Figure 4-5 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0047] Specifically, the flow-blocking member 203 includes a flow-blocking plate 203 a , and a slot 203 b is formed on the connecting pipe 103 , and the flow-blocking plate 203 a is inserted into the slot 203 b .

[0048] By setting the card slot 203b, the baffle plate 203a can be limited and can only move upward. When the baffle plate 203a moves upward to a certain height and fits the inner wall of the connecting tube 103, the baffle plate 203a has a flow-blocking effect in the connecting tube 103, and the glue in the connecting tube 103 stops flowing into the inner chamber 101b.

[0049] Specifically, the spoiler 203 includes an anti-sinking block 203c, and two anti-sinking blocks 203c are respectively fixed on both sides of the spoiler 203a.

[0050] By providing the anti-sinking block 203c, the spoiler 203a can be made more firm and reliable, and the spoiler 203a can be prevented from falling off.

[0051] Specifically, the spoiler 203 includes a suspension plate 203d, and the suspension plate 203d is fixed to the bottom of the spoiler 203a.

[0052] During the glue injection process, the suspension plate 203d is affected by the buoyancy of the liquid, so that the suspension plate 203d rises and drives the baffle plate 203a to move upward. The baffle plate 203a produces a flow blocking effect inside the connecting tube 103, thereby stopping the glue injection into the inner chamber 101b.

[0053] Specifically, the flow blocking member 203 further includes a guide plate 203e. The guide plate 203e is fixed to one end of the connecting pipe 103, and the guide plate 203e is inclined.

[0054] By setting the guide plate 203e, the fluidity of the glue injection inside the connecting pipe 103 can be better enhanced, thereby shortening the glue injection time and improving work efficiency.

[0055] When in use, glue is injected into the two glue injection ports 105 at the same time, and the glue will flow into the inner chamber 101b formed between the two partitions 102 along the glue injection tube 104 and the connecting tube 103, and the glue injection begins. When the glue injected in the inner chamber 101b reaches a certain liquid level, a certain buoyancy will be generated on the suspension plate 203d, so that the suspension plate 203d rises and drives the baffle plate 203a to move upward, so that the baffle plate 203a forms a blocking and flow-blocking effect in the connecting tube 103, thereby stopping the glue injection into the inner chamber 101b. At the same time, during the upward movement of the baffle plate 203a, a certain squeezing force will be generated on the inclined end of the sliding block 202a, pushing the sliding block 202a to move and drive the push plate 202b to move. The push plate 202b pushes the connecting pin 201f away, and the connecting pin 201f is separated from the pin hole 201-1, thereby releasing the restriction on the suspension column 201b and the baffle 201a, causing the baffle 201a to fall downward and separate from the connecting pipe 103, thereby opening the blanking hole 201d. At this time, the glue inside the connecting pipe 103 will flow into the outer chamber 101a, and then the outer chamber 101a can be injected with glue, and the injection of glue is stopped until the injection of glue in the outer chamber 101a is completed, and the glue is waited for to solidify. By utilizing the water flow pressure and water permeability in the outer chamber 101a, the effect of sharply weakening is achieved, thereby improving the waterproof and anti-permeability of the inner chamber 101b, enhancing the sealing ability, avoiding equipment damage and extending the service life.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
