[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0020] like Figures 1 to 4 As shown, a prefabricated building formwork structure includes a base plate 1, and a lifting mechanism 2 is provided on the upper surface of the base plate 1.
[0021] The lifting mechanism 2 includes a support block 201, a second rotating shaft 206, and two limiting slide rods 211. The outer surface of the support block 201 is fixedly connected to the upper surface of the base plate 1, one end of the second rotating shaft 206 is rotatably connected to the upper surface of the base plate 1, and the outer surfaces of the two limiting slide rods 211 are fixedly connected to the bottom surface of the mold frame body 3.
[0022] The inner wall of the support block 201 is rotatably connected to the first rotating shaft 202.
[0023] In this embodiment, the support block 201 can support the first rotating shaft 202, thereby allowing the first rotating shaft 202 to rotate stably when the turntable 203 rotates.
[0024] One end of the first rotating shaft 202 is fixedly connected to a turntable 203, and a rotating rod 204 is fixedly connected to the outer surface of the turntable 203. The end of the first rotating shaft 202 away from the outer surface of the turntable 203 is fixedly connected to a first bevel gear 205.
[0025] Manually rotating the rotating rod 204 causes the turntable 203 and the first rotating shaft 202 to rotate, thereby causing the first rotating shaft 202 to drive the first bevel gear 205 to rotate.
[0026] A second bevel gear 207 is fixedly connected to the outer surface of the second shaft 206. The second bevel gear 207 meshes with the first bevel gear 205. A mounting plate 208 is fixedly connected to the outer surface of the second shaft 206. A threaded rod 209 is fixedly connected to the upper surface of the mounting plate 208.
[0027] While the first bevel gear 205 rotates, it drives the meshing second bevel gear 207 and the second rotating shaft 206 to rotate. As a result, the second bevel gear 207 drives the threaded rod 209 to rotate. At this time, the rotation of the threaded rod 209 can drive the threaded moving block 210 to move up and down, thereby adjusting the height of the mold frame body 3.
[0028] The outer surface of the second rotating shaft 206 is threaded with a moving block 210, and the inner wall of the moving block 210 is slidably connected to the outer surface of the limiting slide rod 211.
[0029] With the limit slider 211 in place, the moving block 210 cannot rotate with the threaded rod 209, thus ensuring that the moving block 210 moves up and down on the surface of the threaded rod 209.
[0030] A mold frame body 3 is provided above the base plate 1. Two component blocks 4 are fixedly connected to the bottom surface of the mold frame body 3. Two symmetrical limiting mechanisms 5 are provided on the inner walls of the two component blocks 4.
[0031] The limiting mechanism 5 includes a component cavity 501, the inner wall of which is formed on the inner wall of the component block 4, a sliding groove 502 is formed on the inner wall of the component cavity 501, and a movable plate 503 is slidably connected to the inner wall of the component cavity 501.
[0032] A pulling block 504 is fixedly connected to the outer surface of the movable plate 503, and the outer surface of the pulling block 504 is slidably connected to the inner wall of the groove 502.
[0033] When it is necessary to release the limit on the sliding column 8, the pulling block 504 is moved. Under the guidance and limit of the sliding groove 502, the moving plate 503 and the insertion rod 506 are driven to slide out of the inner wall of the sliding column 8, thereby releasing the limit on the sliding column 8.
[0034] An elastic component 505 is fixedly connected to the outer surface of the movable plate 503, and one end of the elastic component 505 away from the outer surface of the movable plate 503 is fixedly connected to the inner wall of the component cavity 501.
[0035] In this embodiment, the elastic component 505 is always in a pushing state. Under the pushing of the elastic component 505, the moving plate 503 and the insertion rod 506 are driven to insert into the interior of the sliding column 8.
[0036] The outer surface of the movable plate 503 is fixedly connected to the insertion rod 506, and the outer surface of the insertion rod 506 is inserted into the inner wall of the component block 4 and the inner wall of the sliding column 8.
[0037] In this embodiment, after the insertion rod 506 is inserted into the inner wall of the component block 4 and the sliding column 8, the component block 4 and the sliding column 8 can be combined and limited so that the sliding column 8 cannot be removed from the interior of the component block 4.
[0038] Two sets of symmetrical threaded blocks 6 are fixedly connected to the upper surface of the base plate 1. Two sets of symmetrical sleeves 7 are threadedly connected to the outer surface of the two sets of threaded blocks 6. Sliding columns 8 are slidably connected to the inner walls of the two sleeves 7, and the outer surface of the sliding column 8 is inserted into the inner wall of the component block 4.
[0039] Under the combined action of sleeve 7 and sliding column 8, when the mold frame body 3 is supported, a downward phenomenon occurs. At this time, the sliding column 8 slides inside the sleeve 7, and the inner wall of the sleeve 7 is equipped with a rubber anti-slip layer. Thus, when the sliding column 8 slides inside the sleeve 7, the downward force can be greatly reduced and it can be used for auxiliary support.
[0040] Four base blocks 9 are fixedly connected to the bottom surface of the base plate 1, and two symmetrical storage boxes 10 are fixedly connected to the outer surface of the base plate 1. The two storage boxes 10 can store the disassembled sleeve 7.
[0041] Working principle: When using this embodiment, firstly, insert the sleeves 7 on both sides into the outer surface of the threaded block 6. Then, place the mold frame body 3 and the component block 4 on the slide column 8. During placement, manually pull the pulling block 504 to move the moving plate 503 and the insertion rod 506 into the interior of the component cavity 501. Then, insert the slide column 8 into the interior of the component block 4. Afterward, manually release the pulling block 504. Under the push of the elastic component 505, the moving plate 503 and the insertion rod 506 can be moved until the insertion rod 506 is inserted into the slide column 8 to limit its movement. Then, manually rotate the slide column 8. Rod 204 drives turntable 203 and first rotating shaft 202 to rotate. At this time, first rotating shaft 202 drives first bevel gear 205 to rotate, thereby driving meshing second bevel gear 207 to rotate, thereby driving second rotating shaft 206, mounting plate 208 and threaded rod 209 to rotate. Finally, the rotation of threaded rod 209 drives threaded moving block 210 to move. At this time, the movement of moving block 210 is limited by the combination of limiting slide rod 211, so that moving block 210 can move up and down stably, thereby pushing mold frame body 3 to move up and down.
