[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Reference Figure 2 , Figure 3 and Figure 4 The utility model provides an embodiment: a core-filling template for masonry inspection wells, comprising an outer mold 1, an elastic inner mold 3 is arranged on the inner side of the outer mold 1, a pressure plate 4 is arranged on the top of the elastic inner mold 3, a rotating rod 5 is rotatably connected to the middle part of the top of the pressure plate 4, the bottom end of the rotating rod 5 penetrates the pressure plate 4 and is plugged with a first connecting rod 6, a first bolt 7 is threadedly connected to the front side of the rotating rod 5, the rear end of the first bolt 7 sequentially penetrates the first connecting rod 6 and the rotating rod 5, a connecting sleeve 9 is fixedly connected to the bottom end of the first connecting rod 6, a second connecting rod 10 is arranged inside the connecting sleeve 9, a second bolt 11 is threadedly connected to the front side of the connecting sleeve 9, the rear end of the second bolt 11 sequentially penetrates the connecting sleeve 9 and the second connecting rod 10, the outer sides of the first connecting rod 6 and the second connecting rod 10 are A hollow disc 8 is provided, and a driving bevel gear 12 is fixedly connected to the outer sides of the first connecting rod 6 and the hollow disc 8, and a plurality of fixed plates 13 are evenly and evenly fixedly connected to the inner bottom of the plurality of hollow discs 8, and a screw rod 14 is rotatably connected to the middle part of one side of the fixed plate 13, and one end of the screw rod 14 is fixedly connected to a driven bevel gear 15, and the plurality of driven bevel gears 15 are respectively meshed and connected with the corresponding driving bevel gear 12 around the bottom, and a movable rod 16 is threadedly connected to the outer side of the screw rod 14, and one end of the movable rod 16 penetrates the hollow disc 8 and is fixedly connected to an arc plate 17, and a disassembly mechanism 2 is provided on the outer side of the outer mold 1, and support blocks 25 are evenly and evenly fixedly connected to the outer side of the pressure plate 4, and the size of the pressure plate 4 matches the size of the elastic inner mold 3;

[0041] Specifically, first rotate the rotating rod 5, the first connecting rod 6 and the second connecting rod 10 will rotate accordingly, and the active bevel gear 12 on their outside will also rotate accordingly. Their rotation speed is strictly consistent with the rotation speed of the rotating rod 5. The driven bevel gear 15 will also rotate due to the engagement with the active bevel gear 12. As the driven bevel gear 15 rotates, the screw rod 14 also starts to rotate. Its rotation can drive the outer movable rod 16 to move freely on the outside of the slide rod 19, thereby realizing the adjustment of the size of the elastic inner mold 3. This adjustment mechanism is very practical. It can flexibly adjust the distance between the outer mold 1 and the elastic inner mold 3 according to the actual size of the inspection well, so that the core filling template can adapt to inspection wells of different sizes, greatly improving its reusability. At the same time, due to the existence of this adjustment mechanism, construction personnel do not need to frequently replace templates of different sizes, thereby reducing construction costs and improving work efficiency.

[0042] Reference Figure 1 and Figure 2 The disassembly mechanism 2 includes a connecting block 201 and a transmission belt 205. The multiple connecting blocks 201 are fixedly connected to the upper and lower sides of the outer wall of the outer mold 1 at equal distances. The top of the upper connecting block 201 is provided with a mounting hole 202. The top of the lower connecting block 201 is threadedly connected with a limiting rod 203. The outer side of the limiting rod 203 is fixedly connected with a pulley 204. The multiple pulleys 204 are connected by a transmission belt 205. The bottom ends of the multiple limiting rods 203 pass through the corresponding mounting holes 202 respectively. The bottom end of the elastic inner mold 3 is fixedly connected with an insertion rod 206. The top of the elastic inner mold 3 is provided with a slot 207. The multiple insertion rods 206 are respectively plugged into the corresponding slots 207.

[0043] Specifically, when multiple outer molds 1 and elastic inner molds 3 need to be disassembled or spliced, one of the limit rods 203 is rotated first, and the pulley 204 on the outer side thereof will rotate accordingly. This pulley 204 is not only closely connected to the limit rod 203, but also connected to the pulleys 204 on the outer sides of other limit rods 203 through the transmission belt 205. Therefore, when one limit rod 203 is rotated, the other limit rods 203 will also rotate synchronously. As the limit rods 203 rotate, they will simultaneously rotate out of the mounting holes 202, and the splicing work of the outer mold 1 can be released at this time. When one elastic inner mold 3 is moved upward, the insertion rod 206 at the bottom end of the elastic inner mold 3 will be disengaged from the slot 207 at the top end of another elastic inner mold 3, and the splicing work of the elastic inner mold 3 can be released at this time. This disassembly and installation method is not only simple in structure, but also easy to operate, making the disassembly and installation process easier and faster.

[0044] Reference Figure 2 and Figure 3, the left and right sides of the bottom of the pressing plate 4 and the hollow disc 8 are fixedly connected with a hollow rod 22, a support rod 23 is arranged inside the hollow rod 22, a fourth bolt 24 is threadedly connected to the front side of the hollow rod 22, and the rear ends of the plurality of fourth bolts 24 respectively penetrate the corresponding hollow rod 22 and the support rod 23, and a same connecting plate 20 is fixedly connected to one side of the arc-shaped plate 17 on the same side, and the upper and lower sides of one end of the connecting plate 20 are threadedly connected with a third bolt 21, and one end of the plurality of third bolts 21 respectively penetrates the corresponding connecting plate 20 and the arc-shaped plate 17;

[0045] Specifically, the fourth bolt 24 can be used to release the limiting fixation of the support rod 23, and the hollow disc 8 can be removed at this time, and loosening the third bolt 21 can release the connection between the two arc plates 17. At this time, the corresponding number of hollow discs 8 can be installed and removed according to the length of the elastic inner mold 3.

[0046] Reference Figure 4 and Figure 5 , both sides of the multiple movable rods 16 are fixedly connected with sliders 18, one side of the multiple fixed plates 13 is fixedly connected with multiple slide bars 19, and the sliders 18 are slidably connected with the outer walls of the corresponding slide bars 19 respectively;

[0047] Specifically, the movable track of the movable rod 16 can be limited so that it can move more smoothly.

[0048] Working principle: When using the device, observe the thickness of the well to be filled with core, then carry the outer mold 1 and the elastic inner mold 3 to the desired filling position, then limit and fix the outer mold 1 through the external support device, then cover the elastic inner mold 3 with the pressure plate 4, and then inject concrete into the gap between the outer mold 1 and the elastic inner mold 3 to complete the filling work. When it is necessary to build inspection wells of different sizes, first rotate the rotating rod 5. At this time, the active bevel gear 12 on the outside of the first connecting rod 6 and the second connecting rod 10 will rotate accordingly, and the driven bevel gear 15 meshing with it will also rotate, thereby driving the screw rod 14 to rotate. At this time, the movable rod 16 on the outside of the screw rod 14 will move around on the outside of the sliding rod 19, thereby increasing the size of the elastic inner mold 3, so that the distance between the outer mold 1 and the elastic inner mold 3 can be adjusted according to the actual size of the inspection well, thereby improving the reusability of the core filling template, reducing construction costs, and rotating. When one of the limit rods 203 is moved, the pulley 204 on its outer side will rotate accordingly, and the pulleys 204 on the outer sides of the other limit rods 203 will also rotate via the transmission belt 205, so that multiple limit rods 203 can be inserted into the mounting hole 202 at the same time to complete the splicing of the outer mold 1, and the insertion rod 206 at the bottom end of one of the elastic inner molds 3 is inserted into the slot 207 at the top of another elastic inner mold 3 to complete the splicing of the elastic inner mold 3. At this time, the support rod 23 on the top of the hollow disc 8 is inserted into the corresponding hollow rod 22. Multiple ones can be set according to the height of the spliced ​​elastic inner mold 3, so that the length of the arc plate 17 can match the length of the spliced ​​elastic inner mold 3, making the adjustment work more stable. At the same time, the splicing length of the outer mold 1 and the elastic inner mold 3 can be adjusted according to the height of the inspection well to be built, so that it can be flexibly adjusted according to the actual size of the inspection well, and the disassembly and installation are relatively simple, thereby improving the practicality of the device.
