Technical Field

[0001] The utility model relates to the technical field of embedded parts, and more specifically, the utility model relates to a telescopic embedded part for a precast inspection well. Background Art

[0002] The telescopic embedded part of the precast inspection well can enhance the overall stability of the inspection well through its specific design and structure. These embedded parts are pre-installed at the designated positions during the pouring of concrete and are closely combined with the concrete, thereby improving the bearing capacity and durability of the inspection well.

[0003] In the existing publicly disclosed technical literature, the patent with the patent publication number CN107964984A discloses a new type of closed composite plastic inspection well and its manufacturing process. The embedded part of this inspection well forms a sealed chamber inside the inspection well body that is isolated from the external environment; a polymer is used as the overall material, which can achieve a good sealed environment, no moisture circulation, and a new manufacturing process is realized, ensuring that the dimensional tolerance of the appearance does not exceed the specified value and the service life is good; however, the embedded part of this inspection well has the following defects;

[0004] During the process of pre-embedding and using the embedded part of the inspection well, it is necessary to insert the embedded part into the designated position. After passing through the pre-embedded bolts, the bolts are quickly connected and installed with the inspection well. During the pre-embedding process, due to different pre-embedding depths, it is difficult for the embedded part of the inspection well to be suitable for different inspection wells to achieve the pre-embedding installation operation, which results in poor applicability during pre-embedding use. Therefore, a telescopic embedded part for a precast inspection well is provided. Summary of the Utility Model

A telescopic screw is welded to the top end of the telescopic block.

[0007] Preferably, the outer wall of the sleeve block is slidably connected to the inner wall of the sliding frame, and both the outer wall of the sleeve block and the inner wall of the sliding frame are set as smooth surfaces; the cross-sectional shape of the guiding column is semi-circular, the center point of the telescopic screw rod and the center point of the support column are on the same vertical line, and there is a gap between the telescopic block and the support column; two insertion columns are fixedly connected to the bottom end of the embedded frame, and a pointed column is welded to the bottom end of each insertion column; the cross-sectional area of the top end of the pointed column is larger than that of the bottom end cross-sectional area, and a locking bolt is threadedly connected to the inner wall of the sleeve block, and the locking bolt is used to squeeze the guiding column.

[0008] When this technical solution is in use, the embedded frame is extruded and supported at the upper surface position of the concrete of the precast inspection well.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] As shown in the attached Figures 1-5 A telescopic embedded part of a precast inspection well is shown. A linkage telescopic mechanism is provided on the telescopic embedded part of the precast inspection well. The setting of the linkage telescopic mechanism enables the inspection well embedded part to be pre-embedded and installed using different inspection wells. When the telescopic screw rod 11 is pre-embedded and used, the applicability is wider. The specific structural setting of the linkage telescopic mechanism is as follows.

[0022] In this technical solution, as shown in the attached Figures 1-4As shown, on one side of the inner wall of the embedded frame 1, a sliding frame 2 is welded. At the bottom end of the inner wall of the sliding frame 2, a guiding column 3 is fixedly connected. A linkage telescopic mechanism is arranged on the outer wall of the guiding column 3. The linkage telescopic mechanism includes a sleeve block 4 slidably arranged on the outer wall of the guiding column 3. The bottom end of the sleeve block 4 is fixedly connected with a linkage bar 5.

The top end of the linking block 6 is fixedly connected with a connecting rod 9. The top end of the connecting rod 9 is fixedly installed with a telescopic block 10. A telescopic screw 11 is welded at the top end of the telescopic block 10.

[0023] In this technical solution, as shown in the appendix Figures 2-3 As shown, two insertion columns 12 are fixedly connected to the bottom end of the embedded frame 1. A pointed column 13 is welded to the bottom end of each insertion column 12. The cross-sectional area of the top end of the pointed column 13 is larger than that of its bottom end, so as to facilitate the embedded frame 1 to squeeze the two insertion columns 12. The insertion columns 12 drive the pointed columns 13 to move downward, and the two pointed columns 13 are inserted into the concrete of the precast inspection well. A locking bolt 14 is threadedly connected to the inner wall of the sleeve block 4. The locking bolt 14 is used to squeeze the guiding column 3, so as to rotate the locking bolt 14. The locking bolt 14 squeezes on the guiding column 3 to firmly lock the sleeve block 4.

[0024] When the precast inspection well telescopic embedded part of this technical solution is in use, the embedded frame 1 squeezes the two insertion columns 12. The insertion columns 12 drive the pointed columns 13 to move downward, and the two pointed columns 13 are inserted into the concrete of the precast inspection well. At the same time, the embedded frame 1 squeezes and supports on the upper surface position of the concrete of the precast inspection well. After it solidifies, it can provide a supporting force for the insertion columns 12, and the insertion columns 12 provide a supporting force for the embedded frame 1. By moving the sleeve block 4 upward, the sleeve block 4 slides upward along the outer wall of the guiding column 3 and the inner wall of the sliding frame 2. The sleeve block 4 drives the linkage bar 5 to move upward, and the linkage bar 5 drives the linking block 6 to move upward. The linking block 6 drives the socket ring 7 to slide upward along the outer wall of the support column 8. At the same time, the linking block 6 drives the connecting rod 9 to move upward, and the connecting rod 9 carries the telescopic block 10 to move upward. The telescopic block 10 carries the telescopic screw 11 to move upward. The telescopic screw 11 can realize telescopic upward movement. When it moves upward to the specified position, by rotating the locking bolt 14, the locking bolt 14 is threadedly connected and squeezed with the sleeve block 4. The locking bolt 14 squeezes on the guiding column 3 to firmly lock the sleeve block 4.

[0025] In this technical solution, as shown in the appendix Figures 2-5As shown in the figure, rectangular frames 15 are provided on both sides of the sliding frame 2, and a guiding component is provided on the inner wall of the rectangular frame 15; the guiding component includes a rectangular column 16 slidably arranged on the inner wall of the rectangular frame 15, and a supporting block 17 is fixedly connected to the linkage bar 5; a connecting bar 18 is welded to one side of the rectangular column 16, and the connecting bar 18 is slidably connected to the rectangular frame 15. A supporting block 17 is fixedly connected to one side of the connecting bar 18 and near the bottom end thereof, and a limiting block 19 is welded to the top end of the rectangular column 16. The two rectangular frames 15 are symmetrically arranged with respect to the sliding frame 2. The rectangular column 16 and the rectangular frame 15 are both made of stainless steel. The cross-sectional area of the limiting block 19 is larger than the cross-sectional area of the connecting bar 18, and the outer wall of the connecting bar 18 is a smooth surface.

[0026] When the linkage bar 5 moves vertically upward during the use of this technical solution, the linkage bar 5 drives the two rectangular frames 15 to move upward. The embedded frame 1 supports the supporting block 17, the supporting block 17 supports the rectangular column 16, the rectangular column 16 supports the connecting bar 18, and the connecting bar 18 and the rectangular column 16 perform a guiding operation on the inner wall of the rectangular frame 15. To ensure the stable upward movement of the rectangular frame 15, at the same time, the limiting block 19 performs a vertical limiting operation on the rectangular frame 15, and the linkage bar 5 can stably move upward.
