Description

Technical Field

[0001] This utility model relates to the field of grid tube technology, and in particular to a sleeve mechanism for splicing multi-hole grid tubes for communication engineering. Background Technology

[0002] Porous grid pipe is a composite optical cable sheath pipe made of high-molecular materials such as polyvinyl chloride (PVC) through a one-time extrusion molding process. Its structure includes an outer sheath and multiple independent sub-tube channels integrated within it, forming a regularly arranged porous grid structure. This type of pipe has the characteristics of light weight, smooth inner wall, low wire pulling resistance, and excellent compressive strength, and is widely used in buried laying scenarios such as municipal engineering, communication pipelines, and power cable laying.

[0003] In actual engineering construction, porous grid pipes are usually constructed using a modular splicing method, which involves connecting pipes of the same specifications sequentially to extend the overall length and meet the cable laying requirements for different distances. After splicing, the entire pipeline system will be buried underground, thus placing high demands on the sealing, structural strength, and environmental adaptability of the splicing points. To ensure the stability and safety of the splicing points, a specialized sleeve mechanism is typically used to wrap, protect, and secure the interfaces between adjacent grid pipe sections, preventing damage to the internal cables from groundwater, soil pressure, or insect intrusion.

[0004] Currently, most of the sleeve mechanisms used for splicing multi-hole grid pipes are factory-prefabricated standard parts. Their structural dimensions are designed according to the shape of the grid pipe of a specific specification, and they are only suitable for a single model. For example, a four-hole grid pipe requires a sleeve with the same outer diameter, while a nine-hole grid pipe requires a separate, larger-sized special sleeve. This fixed-size sleeve mechanism has the problems of narrow adaptability and poor versatility. When faced with splicing tasks of grid pipes of various specifications, construction units need to prepare a large number of sleeves of different models, which not only increases inventory management costs but also reduces on-site construction efficiency.

[0005] Therefore, there is an urgent need for a sleeve mechanism that can adapt to the splicing operation between multi-hole grid tubes of various specifications. Utility Model Content

Detailed Implementation

[0032] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0033] Example

[0034] like Figure 1 and Figure 2 As shown in this embodiment, a sleeve mechanism for splicing porous grid tubes for communication engineering is provided. The sleeve mechanism is sleeved at the interface where two adjacent porous grid tubes 1 are spliced. The sleeve mechanism includes a first horizontal telescopic plate 2, a second horizontal telescopic plate 3, two vertical telescopic plates 4, and multiple locking mechanisms 5.

[0035] Specifically, such as Figure 3As shown, the first horizontal telescopic plate 2, the second horizontal telescopic plate 3, and the two vertical telescopic plates 4 are connected end to end to form a rectangular tube structure. Specifically, the two ends of the first horizontal telescopic plate 2 are fixedly connected to the tops of the two vertical telescopic plates 4, and the bottoms of the two vertical telescopic plates 4 are detachably connected to the tops of the two ends of the second horizontal telescopic plate 3, thus forming a rectangular tube structure. Both the first horizontal telescopic plate 2 and the second horizontal telescopic plate 3 can extend and retract laterally along the horizontal side length of the porous grid tube 1, and both vertical telescopic plates 4 can extend and retract vertically along the vertical side length of the porous grid tube 1. The inner walls of the first horizontal telescopic plate 2, the second horizontal telescopic plate 3, and the two vertical telescopic plates 4 can fit tightly against the outer wall of the porous grid tube 1. Multiple locking mechanisms 5 are respectively installed on the first horizontal telescopic plate 2, the second horizontal telescopic plate 3, and the two vertical telescopic plates 4 to lock the extension and retraction lengths of the first horizontal telescopic plate 2, the second horizontal telescopic plate 3, and the two vertical telescopic plates 4. By setting a first horizontal telescopic plate 2, a second horizontal telescopic plate 3, and two vertical telescopic plates 4, the sleeve mechanism can adapt to the splicing requirements of multi-hole grid pipes 1 of different specifications and sizes, such as four-hole, six-hole, and nine-hole pipes. That is, only the first horizontal telescopic plate 2, the second telescopic plate, or the two vertical telescopic plates 4 need to be extended or retracted to change the size of the sleeve mechanism, and the length is fixed by the locking mechanism 5. This allows the sleeve mechanism to accommodate splicing of multi-hole grid pipes 1 of different specifications and sizes, improving the versatility and adaptability of the sleeve mechanism and increasing on-site construction efficiency. Furthermore, the first horizontal telescopic plate 2, the second horizontal telescopic plate 3, and the two vertical telescopic plates 4 can all fit tightly against the outer wall of the multi-hole grid pipe 1, ensuring the sealing of the splicing interface between adjacent multi-hole grid pipes 1, effectively preventing damage to internal cables caused by groundwater, soil pressure, or insect intrusion, and enhancing the adaptability and safety of the entire communication pipeline.

[0036] Furthermore, such as Figure 3As shown, the first transverse telescopic plate 2 includes a first horizontal plate 21, a second horizontal plate 22, and a first movable plate 23. The first horizontal plate 21 and the second horizontal plate 22 are arranged opposite each other, and their opposite ends can fit together. The back ends of the first horizontal plate 21 and the second horizontal plate 22 are respectively fixedly connected to the tops of two vertical telescopic plates 4. The interior of the first horizontal plate 21 and the second horizontal plate 22 are provided with a first mounting groove 211 that communicates with the outside and is arranged laterally towards the porous grid tube 1. The first mounting grooves 211 of the first horizontal plate 21 and the second horizontal plate 22 are arranged opposite each other. The first movable plate 23 is slidably connected in the first mounting grooves 211 of the first horizontal plate 21 and the second horizontal plate 22, which can realize the length adjustment of the first transverse telescopic plate 2 in the transverse direction. That is, by simply moving the first horizontal plate 21 and / or the second horizontal plate 22, the length of the first transverse telescopic plate 2 can be changed, so that the first transverse telescopic plate 2 can adapt to the splicing of porous grid tubes 1 of various specifications and sizes, improving the versatility and applicability of the sleeve mechanism. The side wall of the first movable plate 23 facing the porous grid tube 1 can fit against the outer wall of the porous grid tube 1 to ensure the sealing performance of the sleeve mechanism at the splicing interface of two adjacent porous grid tubes 1 and improve the sealing performance. A locking mechanism 5 is vertically installed on the first horizontal plate 21 and the second horizontal plate 22. The locking end 5a of the locking mechanism 5 can pass through the first horizontal plate 21 or the second horizontal plate 22 and abut against the first movable plate 23 to lock the first movable plate 23, thereby fixing the extension length of the first transverse telescopic plate 2. This effectively prevents the first horizontal plate 21 and the second horizontal plate 22 from being displaced due to external forces, ensuring that the sleeve mechanism maintains good structural stability and sealing performance during long-term buried use.

[0037] Furthermore, such as Figure 3As shown, the two vertical telescopic plates 4 have the same structure, including a vertical plate 41, an L-shaped plate 42, and a second movable plate 43. The top of the vertical plate 41 is fixedly connected to the end of the first horizontal plate 21 or the second horizontal plate 22 away from the axis of the porous grid tube 1. The bottom of the vertical plate 41 can fit against the top of the L-shaped plate 42, and the interior of the vertical plate 41 is provided with a second mounting groove 411 that communicates with the outside and is vertically oriented towards the porous grid tube 1. The second movable plate 43 is vertically oriented and slidably connected in the second mounting groove 411. The side wall of the second movable plate 43 facing the porous grid tube 1 can fit against the outer wall of the porous grid tube 1 to ensure the sealing performance of the sleeve mechanism at the splicing interface of two adjacent porous grid tubes 1 and improve the sealing performance. The bottom of the second movable plate 43 is fixedly connected to the top of the L-shaped plate 42. This allows the length of the vertical telescopic plates 4 to be changed simply by vertically moving the L-shaped plate 42. This enables the two vertical telescopic plates 4 to cooperate with the first horizontal telescopic plate 2, allowing the first horizontal telescopic plate 2 and the two vertical telescopic plates 4 to accommodate the splicing of various specifications and models of porous grid pipes 1, improving the adaptability and versatility of the sleeve mechanism. The bottom of the L-shaped plate 42 is detachably connected to the second horizontal telescopic plate 3. Preferably, the two L-shaped plates 42 are detachably connected to the third horizontal plate 31 and the fourth horizontal plate 32 respectively by bolts 10 and nuts 11, facilitating quick on-site installation and disassembly, and improving the flexibility and operational efficiency of the sleeve mechanism during construction. A locking mechanism 5 is horizontally installed on the vertical plate 41. The locking end 5a can pass through the vertical plate 41 and abut against the second movable plate 43 to lock the second movable plate 43, thereby locking the extension length of the vertical telescopic plate 4. This ensures that the vertical telescopic plate 4 will not loosen or slip due to external force during use, and improves the stability and sealing of the sleeve mechanism.

[0038] It should be noted that the connection between the first horizontal telescopic plate 2 and the two vertical telescopic plates 4 can adopt an arc transition to adapt to the outer contour of the porous grid tube 1.

[0039] Furthermore, such as Figure 3As shown, the second transverse telescopic plate 3 includes a third transverse plate 31, a fourth transverse plate 32, and a third movable plate 33. The third transverse plate 31 and the fourth transverse plate 32 are arranged opposite to each other, and their opposite ends can fit together. The back ends of the third transverse plate 31 and the fourth transverse plate 32 are detachably connected to two L-shaped plates 42, which facilitates the rapid assembly and disassembly of the entire sleeve mechanism and improves the efficiency of assembly and disassembly. Both the third transverse plate 31 and the fourth transverse plate 32 are provided with a third mounting groove 311 that communicates with the outside and is arranged laterally towards the porous grid tube 1. The third mounting grooves 311 of the third transverse plate 31 and the fourth transverse plate 32 are arranged opposite to each other. The third movable plate 33 is slidably connected within the third mounting groove 311 of the third horizontal plate 31 and the fourth horizontal plate 32. It enables the second transverse telescopic plate 3 to adjust its length in the transverse direction; that is, simply moving the third horizontal plate 31 or the fourth horizontal plate 32 is sufficient to adjust the length of the second transverse telescopic plate 3. This allows the sleeve mechanism to further adapt to interfaces of multi-hole grid pipes 1 with different widths, enhancing its versatility and adaptability. The side wall of the third movable plate 33 facing the multi-hole grid pipe 1 can fit against the outer wall of the multi-hole grid pipe 1, ensuring the sealing performance of the sleeve mechanism at the splicing interface of two adjacent grid pipes and improving sealing performance. A locking mechanism 5 is vertically installed on each of the third horizontal plate 31 and the fourth horizontal plate 32. The locking end 5a can pass through the third horizontal plate 31 or the fourth horizontal plate 32 and abut against the third movable plate 33 to lock the third movable plate 33, thus fixing the telescopic length of the second transverse telescopic plate 3. This effectively prevents the vertical telescopic plate 4 from loosening or slipping due to external force, improving the stability and sealing performance of the sleeve mechanism.

[0040] Furthermore, such as Figure 3 As shown, the outer walls of the locking ends 5a of the first movable plate 23, the second movable plate 43, and the third movable plate 33 facing the locking mechanism 5 are all provided with multiple locking grooves 6. These locking grooves 6 are spaced apart along the side length direction of the corresponding porous grid tubes 1 of the first movable plate 23, the second movable plate 43, and the third movable plate 33. The locking end 5a can abut against the locking groove 6 to lock the first movable plate 23, the second movable plate 43, or the third movable plate 33. By providing the locking grooves 6, the locking end 5a can selectively engage with locking grooves 6 at different positions, thereby adjusting and fixing the extension lengths of the first transverse telescopic plate 2, the second transverse telescopic plate 3, and the vertical telescopic plate 4. This effectively prevents structural loosening due to external pressure or soil settlement, ensuring the long-term sealing and structural stability of the splicing interface.

[0041] Furthermore, such as Figure 5 , Figure 6 and Figure 7As shown, limiting blocks 7 are provided on both sides of the first movable plate 23 and the third movable plate 33, and on both sides of the second movable plate 43 at the end away from the L-shaped plate 42. Sliding grooves 8 are provided on both inner sides of the first mounting groove 211, the second mounting groove 411, and the third mounting groove 311. The limiting blocks 7 are placed in their corresponding sliding grooves 8 to limit the sliding range of the first movable plate 23, the second movable plate 43, and the third movable plate 33, respectively. This achieves guidance and limits the sliding range of the first movable plate 23, the second movable plate 43, and the third movable plate 33 during the extension and retraction process, preventing the first movable plate 23, the second movable plate 43, and the third movable plate 33 from detaching from the first horizontal plate 21 and the second horizontal plate 22, the vertical plate 41, the third horizontal plate 31, and the fourth horizontal plate 32, respectively, during the sliding process.

[0042] Furthermore, such as Figure 4As shown, the multiple locking mechanisms 5 have the same structure, including a locking rod 51, a limiting plate 52, an elastic element 53, and a pull rod assembly 54. The first horizontal plate 21, the second horizontal plate 22, the third horizontal plate 31, the fourth horizontal plate 32, and the vertical plate 41 all have a moving space 9 inside. The locking rod 51 is slidably inserted into the moving space 9 and the first horizontal plate 21, the second horizontal plate 22, the third horizontal plate 31, the fourth horizontal plate 32, or the vertical plate 41. The end of the locking rod 51 facing the locking groove 6 is the locking end 5a. By engaging the locking end 5a with the locking groove 6 on the first movable plate 23, the second movable plate 43, or the third movable plate 33, the telescopic length is fixed, allowing for multi-length adjustment according to the different dimensions of the porous grid tube 1, thus improving the adaptability and versatility of the sleeve mechanism. Both the limiting plate 52 and the elastic element 53 are placed within the moving space 9. The limiting plate 52 is fixedly sleeved on the outer wall of the locking rod 51, which can limit the movement range of the locking rod 51 and prevent the locking rod 51 from disengaging from the first horizontal telescopic plate 2, the second horizontal telescopic plate 3, or the two vertical telescopic plates 4 when sliding. The elastic element 53 is sleeved on the outer periphery of the locking rod 51, and the two ends of the elastic element 53 abut against the side wall of the limiting plate 52 and the moving space 9 away from the porous grid tube 1, respectively. The elastic element 53 can provide buffering force and rebound force for the limiting plate 52. The pull rod assembly 54 is located outside the first horizontal plate 21, the second horizontal plate 22, the third horizontal plate 31, the fourth horizontal plate 32, or the vertical plate 41. The pull rod assembly 54 is fixedly connected to the end of the locking rod 51 away from the locking end 5a, so as to drive the locking rod 51 to move along its own axis. When the pull rod assembly 54 drives the locking rod 51 and the limiting plate 52 to move simultaneously along the axial direction of the locking rod 51 away from the locking groove 6, the elastic element 53 provides a buffering force for the limiting plate 52, preventing the limiting plate 52 from colliding hard with the inner wall of the moving space 9. When locking is required, simply release the pull rod assembly 54. Due to its own rebound force, the elastic element 53 drives the limiting plate 52 and the locking rod 51 to move simultaneously towards the locking groove 6, thereby resetting the locking rod 51 and the limiting plate 52. This operation is simple and convenient, improving locking efficiency. Preferably, a rubber pad can be bonded at the locking end 5a, with the contour of the rubber pad being the same as that of the locking end 5a, to increase the friction between the locking end 5a and the locking groove 6.

[0043] Furthermore, such as Figure 4As shown, the pull rod assembly 54 includes a pull ring 541 and a mounting block 542. The mounting block 542 is located externally and is fixedly mounted on the end of the locking rod 51 away from the locking end 5a. The pull ring 541 is fixedly mounted on the side wall of the mounting block 542 away from the locking rod 51. The pull ring 541 can drive the mounting block 542, the locking rod 51, and the limiting plate 52 to move simultaneously away from the locking groove 6, so that the locking end 5a disengages from the locking groove 6. By setting the pull ring 541 and the mounting block 542, it is easier to disengage the locking end 5a from the locking groove 6. When the pull ring 541 is pulled, the pull ring 541 can simultaneously drive the mounting block 542, the locking rod 51, and the limiting plate 52 to move along the axial direction of the locking rod 51 away from the first movable plate 23, the second movable plate 43, or the third movable plate 33, so that the locking end 5a disengages from the locking groove 6, and the elastic member 53 provides a buffering force for the limiting plate 52. When the pull ring 541 is released, the elastic element 53 can provide a rebound force to the limiting plate 52, so that the limiting plate 52 simultaneously drives the locking rod 51, the mounting block 542 and the pull ring 541 to move along the axial direction of the locking rod 51 toward the first movable plate 23 or the second movable plate 43 or the third movable plate 33, so that the locking end 5a is placed in the locking groove 6.

[0044] Furthermore, such as Figure 4 As shown, the locking end 5a is a hemispherical structure, and the locking groove 6 is a hemispherical groove corresponding to the hemispherical structure. The two are stably engaged through curved surface contact, so that the locking rod 51 has guiding and centering capabilities during the locking process with the locking groove 6, and the locking end 5a can enter the locking groove 6 more smoothly.

[0045] Based on the above structure, the working principle of the sleeve mechanism for splicing porous grid tubes for communication engineering in this embodiment is as follows:

[0046] First, assemble the sleeve mechanism. Place the first movable plate 23 in the first mounting groove 211, place the two second movable plates 43 in the second mounting groove 411, and place the third movable plate 33 in the third mounting groove 311. This allows the construction personnel to observe that the inner side length of the first horizontal telescopic plate 2 and the two vertical telescopic plates 4 is greater than the outer side length of the corresponding porous grid pipe 1. Then, fix the length of the first horizontal telescopic plate 2, the second horizontal telescopic plate 3, and the two vertical telescopic plates 4 by engaging the locking end 5a of the locking rod 51 with the locking groove 6.

[0047] Then adjust the length of the first horizontal telescopic plate 2. Place the first horizontal telescopic plate 2 and two vertical telescopic plates 4 on the porous grid tube 1, with the inner wall of the first horizontal telescopic plate 2 and one vertical telescopic plate 4 facing the inner wall of the porous grid tube 1 and their corresponding outer wall. Pull the pull ring 541 on the first horizontal plate 21 or the second horizontal plate 22, causing it to move the corresponding mounting block 542, locking rod 51, and limiting plate 52 simultaneously along the axial direction of the locking rod 51 away from the locking groove 6, so that the first horizontal plate 21 or the second horizontal plate 22 is in an active state with the first movable plate 23. At this time, the elastic element 53 is in a compressed state to provide a buffering force for the limiting plate 52. Then move the first horizontal plate 21 or the second horizontal plate 22 laterally to adjust the length of the first horizontal telescopic plate 2, and move the other vertical telescopic plate 4 towards the porous grid tube 1 until the inner wall of the other vertical telescopic plate 4 facing the porous grid tube 1 is in contact with the outer wall of its corresponding porous grid tube 1. Then, the pull ring 541 is released. Due to its own rebound force, the elastic element 53 drives the limiting plate 52, the locking rod 51 and the mounting block 542 to move simultaneously along the axial direction of the locking rod 51 toward the direction close to the locking groove 6, until the locking end 5a is placed in the locking groove 6, thus completing the locking of the first horizontal plate 21 or the second horizontal plate 22 with the first movable plate 23. Alternatively, when the movable range of the first horizontal plate 21 or the second horizontal plate 22 is insufficient, that is, when the end of the first movable plate 23 abuts against the end of the first mounting groove 211 of its corresponding first horizontal plate 21 or the second horizontal plate 22, the first movable plate 23 can be locked to the first horizontal plate 21 or the second horizontal plate 22 firstly by locking end 5a and locking groove 6, and then the pull ring 541 of another locking mechanism 5 can be pulled to make the second horizontal plate 22 or the first horizontal plate 21 and the first movable plate 23 in an active state. Then the second horizontal plate 22 or the first horizontal plate 21 can be moved so that the inner wall of the two vertical telescopic plates 4 facing the porous grid tube 1 fits against the outer wall of its corresponding porous grid tube 1. Alternatively, the locking mechanism 541 on the first horizontal plate 21 and the second horizontal plate 22 can be pulled simultaneously, so that the first horizontal plate 21 and the second horizontal plate 22 and the first movable plate 23 are both in an active state. Then, the first horizontal plate 21 and the second horizontal plate 22 can be moved simultaneously, so that the inner walls of the two vertical telescopic plates 4 facing the porous grid tube 1 respectively fit against the outer walls of their corresponding porous grid tube 1. Finally, the two pull rings 541 can be released to fix the length of the first horizontal telescopic plate 2.

[0048] Next, adjust the lengths of the two vertical telescopic plates 4. Taking one vertical telescopic plate 4 as an example, pull the pull ring 541 horizontally, causing the mounting block 542, locking rod 51, and limiting plate 52 to move simultaneously away from the locking groove 6 on the second movable plate 43, so that the locking end 5a disengages from the locking groove 6. At this time, the elastic element 53 is compressed to provide a buffering force for the limiting plate 52. Then, move the L-shaped plate 42 vertically, causing the second movable plate 43 connected to it to move vertically within the second mounting groove 411. When the construction personnel observe that the bottom wall of the L-shaped plate 42 is flush with the outer wall of the corresponding porous grid tube 1, stop moving the L-shaped plate 42 and release the pull ring 541. Due to the rebound force of the elastic element 53, the locking rod 51, limiting plate 52, mounting block 542, and pull ring 541 move simultaneously towards the locking groove 6, so that the locking end 5a is placed in the locking groove 6, thereby fixing the second movable plate 43. The length adjustment of the other vertical telescopic plate 4 is also performed in accordance with the above operation, and will not be described in detail here.

[0049] After adjusting the lengths of the two vertical telescopic plates 4, adjust the length of the second horizontal telescopic plate 3. First, make the bolt holes 10 on the third horizontal plate 31 or the fourth horizontal plate 32 coaxial with the bolt holes 10 on the corresponding L-shaped plate 42. Fix the L-shaped plate 42 and the third horizontal plate 31 or the fourth horizontal plate 32 with bolts 10 and nuts 11. At this time, the inner wall of the second horizontal telescopic plate 3 facing the porous grid hole is in contact with the outer wall of the corresponding porous grid tube 1. Then, pull the pull ring 541 on the third horizontal plate 31 or the fourth horizontal plate 32 to drive the mounting block 542, locking rod 51 and limiting plate 52 corresponding to the pull ring 541 to move simultaneously away from the locking groove 6 on the third movable plate 33. At this time, the elastic element 53 is compressed to provide a buffering force for the limiting plate 52. Then move the fourth horizontal plate 32 or the third horizontal plate 31 so that the bolt holes 10 on the fourth horizontal plate 32 or the third horizontal plate 31 are coaxial with the bolt holes 10 on the corresponding L-shaped plate 42. Alternatively, when the movable range of the third horizontal plate 31 or the fourth horizontal plate 32 is insufficient, i.e., when the end of the third movable plate 33 abuts against the end of the third mounting groove 311 of its corresponding third horizontal plate 31 or the fourth horizontal plate 32, the third movable plate 33 can first be locked to the third horizontal plate 31 or the fourth horizontal plate 32 by the locking end 5a and the locking groove 6. Then, pull the pull ring 541 of another locking mechanism 5 to drive the mounting block 542, the locking rod 51, and the limiting plate 52 to move simultaneously away from the locking groove 6, so that the locking end 5a disengages from the locking groove 6, and the fourth horizontal plate 32 or the third horizontal plate 31 and the third movable plate 33 are in an active state. At this time, the elastic element 53 is in a compressed state to provide a buffering force for the limiting plate 52. Then, move the fourth horizontal plate 32 or the third horizontal plate 31 so that the bolt 10 hole on the fourth horizontal plate 32 or the third horizontal plate 31 is coaxial with the bolt 10 hole on its corresponding other L-shaped plate 42. At this point, the bolt holes 10 on the third horizontal plate 31 and the fourth horizontal plate 32 are coaxial with the bolt holes 10 on their corresponding L-shaped plates 42. Finally, the other L-shaped plate 42 and the fourth horizontal plate 32 or the third horizontal plate 31 are fixed by bolts 10 and nuts 11, thereby completing the sleeve mechanism being fitted onto the splicing interface of two adjacent porous grid tubes 1 for sleeve connection, protection and sealing.

[0050] Of course, you can first adjust the first horizontal telescopic plate 2 according to the above operation. After the inner walls of the two vertical telescopic plates 4 are in contact with the outer walls of their corresponding porous grid tubes 1, connect the second horizontal telescopic plate 3 to the two vertical telescopic plates 4 using bolts 10 and nuts 11 according to the above operation. Then, pull the pull rings 541 of the locking mechanisms 5 on the two vertical telescopic plates 4 simultaneously according to the above operation, so that the two movable plates and the two vertical plates 41 are all in an active state. Then, move the second horizontal telescopic plate 3 vertically upward to simultaneously drive the two L-shaped plates 42 and the two second movable plates 43 to move. Until the inner wall of the second horizontal telescopic plate 3 facing the porous grid tube 1 is in contact with the outer wall of its corresponding porous grid tube 1, at this time, determine the length of the two vertical telescopic plates 4. Finally, release the pull rings 541 of the two locking mechanisms 5 on the vertical telescopic plates 4, so that the locking ends 5a of the two locking rods 51 are respectively placed in the locking grooves 6 on the two second movable plates 43, thereby locking the length of the two vertical telescopic plates 4 and completing the sleeve mechanism's sleeve connection, protection, and sealing.
