[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] However, when pouring concrete into the mold, due to the large tension of the concrete, the extrusion on the mold will be large, and after forming, the mold will adhere to the outer wall of the mold. When disassembling, workers need to use machines to separate the mold from the inspection well, resulting in a reduction in work efficiency.

[0021] In view of this, the present invention provides a high-precision inspection well chamber mold, which solves the problem that when pouring concrete into the mold, due to the large tension of the concrete, the extrusion on the mold is large, and after forming, the mold adheres to the outer wall of the mold. When disassembling, workers need to use machines to separate the mold from the inspection well, resulting in a reduction in work efficiency.

[0022] Through the personnel in the field, the components in this case are connected in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0023] Embodiment 1: Consisting of Figures 1-4It can be known that a high-precision inspection well chamber mold includes a base 1. A bottom plate 2 is fixedly connected to the top of the base 1. An inner mold tube 4 is attached to the top of the bottom plate 2. The inner mold tube 4 and the outer mold tube 3 are used in a matching manner to make the size of the inspection well more accurate during pouring. An outer mold tube 3 is arranged on the outer wall of the inner mold tube 4. A limiting column 6 is inserted into the inner wall of the outer mold tube 3. The limiting column 6 is used to make the outer mold tube 3 stable during mold opening and closing, avoiding inaccurate pouring dimensions. The outer wall of the limiting column 6 is fixedly connected to the inner wall of the base 1. A cover plate 5 is attached to the top of the inner mold tube 4. A driving structure is installed on the outer wall of the outer mold tube 3. The driving structure includes a connecting rod 9, a slider 8, a threaded rod 17, and a fixing plate 7. One end of the connecting rod 9 is rotatably connected to the outer wall of the outer mold tube 3. The other end of the connecting rod 9 is rotatably connected to a slider 8. The outer wall of the slider 8 is slidably clamped to a fixing plate 7. The bottom of the fixing plate 7 is fixedly connected to the top of the base 1. The inner wall of the slider 8 is threadedly connected to a threaded rod 17. The outer wall of the threaded rod 17 is rotatably connected to the inner wall of the fixing plate 7 through a bearing;

[0024] In the specific implementation process, it is particularly worth noting that, with the cooperation of the threaded rod 17, the slider 8, and the connecting rod 9, after the concrete dries and forms, the threaded rod 17 is rotated. By using the meshing of the threaded rod 17 and the slider 8, when the threaded rod 17 rotates, it drives the slider 8 to move inside the fixing plate 7, causing the connecting rod 9 to drive the outer mold tube 3 to separate from the formed concrete, making it more convenient for workers to separate the mold and improving work efficiency;

[0025] Furthermore, a driven gear 16 is fixedly connected to the outer wall of the threaded rod 17. The outer wall of the driven gear 16 is meshed with a driving gear 15. The driving gear 15 and the driven gear 16 are bevel gears and can mesh and transmit power. A driving rod 14 is fixedly connected to the outer wall of the driving gear 15. The outer wall of the driving rod 14 is rotatably connected to the inner wall of the fixing plate 7 through a bearing. One end of the driving rod 14 extending to the outer wall of the fixing plate 7 is fixedly connected to a handle 13;

[0026] In the specific implementation process, it is particularly worth noting that, with the cooperation of the driving gear 15, the driven gear 16, and the driving rod 14, during mold opening and closing, the handle 13 is used to rotate the driving rod 14, driving the driving gear 15 to rotate, and using the meshing of the driving gear 15 and the driven gear 16 to drive the threaded rod 17 to rotate, causing the connecting rod 9 to drive the outer mold tube 3 to move;

[0027] Furthermore, a hanging ring 12 is installed on the top of the cover plate 5;

[0028] In the specific implementation process, it is particularly worth noting that, with the cooperation of the cover plate 5 and the hanging ring 12, during mold opening, the hanging ring 12 is used to separate the cover plate 5 from the outer mold tube 3, facilitating the separation of the cover plate 5;

[0029] Specifically, when using this high-precision inspection well chamber mold, the handle 13 is used to drive the drive rod 14 to rotate, and by utilizing the meshing of the driving gear 15 and the driven gear 16, the threaded rod 17 is rotated, driving the slider 8 to move inside the fixed plate 7, causing the connecting rod 9 to drive the outer mold tube 3 to separate. The limit post 6 can also ensure the stable movement of the outer mold tube 3, preventing inaccurate pouring dimensions. After the concrete dries and forms, the hanging ring 12 is used to remove the cover plate 5 from inside the outer mold tube 3, and by rotating the handle 13 in the reverse direction, it is more labor-saving to separate the outer mold tube 3.

[0030] Embodiment 2: As Figures 1-4 can be seen, a spring 19 is tightly abutted against the inner wall of the top of the cover plate 5, one end of the spring 19 is tightly abutted against a clamping block 20, the outer wall of the clamping block 20 is movably connected to the inner wall of the cover plate 5, and the end of the clamping block 20 extending to the outer wall of the cover plate 5 is inserted into the outer wall of the outer mold tube 3. A positioning bolt 18 is inserted into the top of the cover plate 5, and the end of the positioning bolt 18 extending to the outer wall of the cover plate 5 is inserted into the inner wall of the outer mold tube 3;

[0031] During the specific implementation process, it is particularly worth noting that with the cooperation of the spring 19, the clamping block 20 and the positioning bolt 18, after the outer mold tube 3 is closed, the cover plate 5 is installed inside the outer mold tube 3. After being completely inserted into the outer mold tube 3, the clamping block 20 will be inserted into the outer mold tube 3 under the action of the spring 19 to fix the cover plate 5. Moreover, after being clamped, the positioning bolt 18 is inserted into the top of the cover plate 5 to prevent the problem that when pouring concrete, the extrusion force of the concrete tension on the cover plate 5 is too large, causing the cover plate 5 to fall off from the outer mold tube 3;

[0032] Furthermore, an insertion block 10 is fixedly connected to the inner wall of the inner mold tube 4, an insertion post 11 is inserted into the inner wall of the insertion block 10, and the bottom of the insertion post 11 is fixedly connected to the top of the bottom plate 2;

[0033] During the specific implementation process, it is particularly worth noting that with the cooperation of the insertion block 10, the insertion post 11 and the bottom plate 2, when demolding, when using the hanging ring 12 to separate the inner mold tube 4, it will drive the inner mold tube 4 to be pulled out of the concrete. And when placing the inner mold tube 4, the insertion block 10 is inserted on the outer wall of the insertion post 11 to make the placement position of the inner mold tube 4 more accurate and avoid errors;

[0034] Specifically, on the basis of the above-mentioned embodiment, when demolding, when the cover plate 5 is lifted through the hanging ring 12, it will drive the inner mold tube 4 to separate in the concrete. And when closing the mold, the insertion block 10 is inserted on the outer wall of the insertion post 11 to make the dimensions of the inner mold tube 4 and the outer mold tube 3 more accurate and avoid errors.
