[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0025] See also Figures 1 to 4 , provided as an embodiment of the utility model, a pre-buried grounding galvanized steel plate positioning clamp comprises a galvanized steel plate 1, a horizontal plate 4 is fixedly connected to the lower surface of the galvanized steel plate 1, side plates 5 are fixedly installed on both sides of the horizontal plate 4, the side plates 5 are L-shaped, a bidirectional screw rod 41 is rotatably connected inside the horizontal plate 4, a symmetrical clamping block 43 is threadedly connected to the surface of the bidirectional screw rod 41, the clamping block 43 is slidably connected to the inside of the side plate 5, steel bars 6 are movably installed inside the two side plates 5, the clamping block 43 is in contact with the steel bars 6, the bidirectional screw rod 41 is rotated by a turntable 42, so that the two clamping blocks 43 are close to each other to clamp and fix the steel bars 6, thereby facilitating the positioning of the galvanized steel plate 1.

[0026] For the above example, those skilled in the art should know that the moving structure of the two clamping blocks 43 can be adjusted. For example, a hydraulic rod or a cylinder can be provided to fit the two clamping blocks 43 so that the clamping blocks 43 can fit toward the middle.

[0027] Specifically, a first bevel gear 45 is fixedly installed on the surface at the other end of the bidirectional screw rod 41, a rotating bracket 51 is rotatably connected inside the two side plates 5, and second bevel gears 52 are fixedly installed at both ends of the rotating bracket 51. The two first bevel gears 45 are meshed with the second bevel gear 52 at one end of the rotating bracket 51. A threaded rod 53 is rotatably connected inside the two side plates 5, and a third bevel gear 54 is fixedly installed on the end of the threaded rod 53. The third bevel gear 54 is meshed with the second bevel gear 52 at the other end of the rotating bracket 51. A sealing block 55 is slidably connected inside the side plate 5, and an internal thread 56 is provided inside the sealing block 55, and the threaded rod 53 is meshed with the internal thread 56.

[0028] In the embodiment of the utility model, when the bidirectional screw 41 rotates, the rotating bracket 51 can be rotated through the engagement of the first bevel gear 45 and the second bevel gear 52, and the threaded rod 53 can be rotated through the engagement of the second bevel gear 52 and the third bevel gear 54, so that the sealing block 55 is squeezed out to form a sealing structure with the cross plate 4 and the side plate 5, thereby fixing the steel bar 6.

[0029] For the above example, those skilled in the art should know that the structure of the bevel gear can be adjusted. For example, a belt and a pulley structure can be used to drive the threaded rod 53 to rotate when the bidirectional screw 41 rotates.

[0030] Specifically, the transverse plate 4 , the two side plates 5 and the two sealing blocks 55 are in a square shape.

[0031] In the embodiment of the utility model, the square shape seals the steel bar 6 , further increasing the stability of the steel bar 6 .

[0032] Specifically, a slide groove 44 is provided inside the transverse plate 4 , and the protrusions of the two clamping blocks 43 are slidably connected inside the slide groove 44 .

[0033] In the embodiment of the utility model, the clamping block 43 slides inside the sliding groove 44, thereby improving the sliding stability of the clamping block 43.

[0034] For the above example, those skilled in the art should know that the structure of the slide groove 44 can be adjusted. For example, a guide rod can be provided to be slidably connected to the clamp block 43, so that the clamp block 43 is more stable when moving.

[0035] Specifically, one end of the bidirectional screw rod 41 passes through the left side panel 5 and is fixedly mounted with a turntable 42, and an insertion rod 47 is slidably connected inside the turntable 42. A plurality of insertion holes 57 are opened on the surface of the left side panel 5, and the insertion holes 57 are distributed in a circular shape on the surface of the side panel 5. The insertion rod 47 is movably inserted inside the insertion holes 57.

[0036] In the embodiment of the utility model, when the clamp block 43 is in contact with the steel bar 6, the bidirectional screw rod 41 stops rotating, and the insertion rod 47 is inserted into the insertion hole 57, so that the bidirectional screw rod 41 can be fixed to avoid rotation due to external force.

[0037] For the above example, those skilled in the art should know that the structure of the plug rod 47 and the socket 57 can be adjusted. For example, the plug rod 47 can be replaced by a bolt, and the socket 57 is set as a screw hole, so as to limit the rotation of the bidirectional screw rod 41.

[0038] Specifically, a sliding groove 48 is opened inside the turntable 42, and an insertion rod 47 is slidably connected inside the sliding groove 48. A limit ring 49 is fixedly installed on the surface of the insertion rod 47, and a spring 401 is fixedly installed on the surface of the limit ring 49. The other end of the spring 401 is fixedly connected inside the sliding groove 48.

[0039] In the embodiment of the utility model, the spring 401 cooperates with the limiting ring 49 so that the insertion rod 47 can be inserted into the insertion hole 57 .

[0040] Specifically, an anti-sliding block 46 is fixedly mounted on the surface of the clamping block 43 .

[0041] In the embodiment of the utility model, the anti-sliding block 46 further increases the friction between the clamping block 43 and the surface of the steel bar 6, thereby making the steel bar 6 more stable.

[0042] Specifically, a positioning member 2 is fixedly installed on the lower surface of the galvanized steel plate 1 , a symmetrical connecting member 3 is fixedly connected to the surface of the positioning member 2 , and an end of the connecting member 3 is fixedly connected to the cross plate 4 .

[0043] In the embodiment of the utility model, the galvanized steel sheet 1 can be positioned by connecting the positioning member 2 with the connecting member 3 .

[0044] During use, when it is necessary to move the clamping block 43 according to the size of the steel bar 6, the insertion rod 47 is pulled out and the turntable 42 is rotated. The turntable 42 drives the bidirectional screw rod 41 to rotate, so that the two clamping blocks 43 move toward the middle to clamp the steel bars 6 of different sizes. After loosening the insertion rod 47, the insertion rod 47 is inserted into the appropriate insertion hole 57 to fix the bidirectional screw rod 41, preventing the bidirectional screw rod 41 from rotating and causing the two clamping blocks 43 to move, which is suitable for clamping and fixing steel bars 6 of different sizes, further improving the positioning effect. When the bidirectional screw rod 41 rotates, the first bevel gear 45 on the surface and the end rotates, and through linkage, the sealing block 55 inside the side plate 5 can be moved out, and the two sealing blocks 55 fit together with the cross plate 4 and the side plate 5 to form a U-shape, thereby surrounding the steel bar 6, so that the clamping of the steel bar 6 is more stable.
