[0028] This part will describe the specific embodiments of the present utility model in detail. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0029] Please refer to Figures 1-3 , the present utility model provides a technical solution: a protective fence for building houses, including two counterweight blocks 1. T-shaped chutes 5 are opened at the top ends of the opposite surfaces of the two counterweight blocks 1, and clamping blocks 2 are slidably installed inside the two T-shaped chutes 5;

[0030] A groove 15 is opened at the bottom surface of the clamping block 2, a rack 6 is fixedly installed on the inner wall of the groove 15, and a gear 7 is meshed with the rack 6;

[0031] A storage groove 14 is opened at the bottom surface of the counterweight block 1, a support block 9 is slidably installed inside the storage groove 14, and universal wheels are installed at the four corners of the lower surface of the support block 9;

[0032] A guide rod is slidably inserted into one side of the upper surface of the support block 9, and the top end of the guide rod is fixedly installed at the top end inside the storage groove 14. When the support block 9 moves, the guide rod plays a limiting role on the support block 9, making the movement process of the support block 9 more stable.

[0033] On the other side of the upper surface of the support block 9, a fixed column is fixedly installed; a circular groove is opened at the position corresponding to the fixed column at the inner top of the storage groove 14, and the circular groove is adapted to the fixed column; a lead screw 8 is threadedly connected to the fixed column; the top end of the lead screw 8 is fixedly connected to the gear 7; the bottom end of the lead screw 8 slides through to the bottom of the support block 9; the lead screw 8 is rotationally connected to the counterweight 1. When the block 2 moves outward from the counterweight 1, it drives the rack 6 to move. The movement of the rack 6 drives the gear 7 to rotate forward. The forward rotation of the gear 7 drives the lead screw 8 to rotate, thereby driving the fixed column and the support block 9 to move upward, so that the fixed column moves into the circular groove. When the fixed column moves to the inner top of the circular groove, at this time, the support block 9 also just moves to the inner top of the storage groove 14. By setting the cooperation of the fixed column and the circular groove, it is avoided that the support block 9 directly contacts the top of the storage groove 14 and generates extrusion during the upward movement. And when the block 2 is pushed back to its original position, the reverse rotation of the gear 7 drives the lead screw 8 to rotate, thereby causing the support block 9 to move downward. And when the block 2 returns to its original position, the universal wheel on the support block 9 has contacted the ground and the support block 9 has not disengaged from the lead screw 8.

[0034] Further, the block 2 includes a T-shaped bottom plate, and the T-shaped bottom plate is slidably connected to the T-shaped chute 5; a protrusion is integrally formed on the upper surface of the T-shaped bottom plate. By setting the protrusion, it is convenient for the staff to dial the protrusion to move the block 2; a connecting block is integrally formed on the lower surface of the T-shaped bottom plate on the side far from the protrusion.

[0035] Further, a chute 13 is opened on the inner bottom surface of the T-shaped chute 5 on the side far from the groove 15, and the connecting block at the bottom end of the block 2 is slidably connected to the chute 13; a slide bar 12 is fixedly installed inside the chute 13; a guide hole is opened at the position corresponding to the slide bar 12 on the connecting block, and the end of the slide bar 12 far from the chute 13 is slidably inserted into the guide hole.

[0036] Further, a spring 11 is fixedly installed at the position corresponding to the slide bar 12 inside the chute 13. The spring 11 is sleeved on the outside of the slide bar 12, and the other end of the spring 11 is fixedly connected to the connecting block.

[0037] Further, clamping blocks are integrally formed on the opposite ends of the two blocks 2; clamping grooves are opened at the positions corresponding to the clamping blocks inside the two T-shaped chutes 5; clamping grooves are opened at the positions corresponding to the clamping blocks on the outer sides of the two insertion posts 3.

[0038] Furthermore, on the side close to the bottom surfaces of the two T-shaped sliding grooves 5, slots 10 are respectively formed. Plug posts 3 are slidably inserted into the interiors of the two slots 10. Connecting plates are fixedly installed at the tops of the two plug posts 3. Two telescopic rods 4 are fixedly installed on the opposite surfaces of the two connecting plates. Pull the two clamping blocks 2 outwards towards the outside of the counterweight 1. The movement of the clamping blocks 2 drives the springs 11 to contract, so that the springs 11 have the force to restore the clamping blocks 2 to their original states. And through the sliding fit between the connecting blocks at the bottoms of the clamping blocks 2 and the sliding rods 12, the movement process of the clamping blocks 2 is more stable. Subsequently, insert the two plug posts 3 into the corresponding slots 10. After that, release the clamping blocks 2. The elongation of the springs 11 drives the clamping blocks 2 to slide into the corresponding T-shaped sliding grooves 5, so that the clamping blocks on the clamping blocks 2 are clamped into the corresponding slots of the plug posts 3, thereby clamping the plug posts 3 on the counterweight 1. And at this time, the support block 9 and the universal wheels at its bottom end are still received in the receiving groove 14.

[0039] Working principle: When in use, move the clamping block 2 outwards from the counterweight 1, drive the rack 6 to move. The movement of the rack 6 drives the gear 7 to rotate forward. The forward rotation of the gear 7 drives the lead screw 8 to rotate, thereby driving the fixed column and the support block 9 to move upwards, so that the fixed column moves into the circular groove. When the fixed column moves to the top end inside the circular groove, at this time, the support block 9 also just moves to the top end inside the receiving groove 14, so that the lower surface of the counterweight 1 contacts the ground, preventing the counterweight 1 from moving due to external force factors. By setting the cooperation between the fixed column and the circular groove, it is avoided that the support block 9 directly contacts the top end of the receiving groove 14 and generates extrusion during the upward movement process. And when the clamping block 2 is pushed back to its original position, the gear 7 rotates in reverse to drive the lead screw 8 to rotate, thereby causing the support block 9 to move downwards. When the clamping block 2 returns to its original position, the universal wheels on the support block 9 contact the ground, so that the lower surface of the counterweight 1 leaves the ground, and at this time, the support block 9 does not disengage from the lead screw 8.

[0040] Pull the two clamping blocks 2 outwards towards the outside of the counterweight 1. The movement of the clamping blocks 2 drives the springs 11 to contract, so that the springs 11 have the force to restore the clamping blocks 2 to their original states. And through the sliding fit between the connecting blocks at the bottoms of the clamping blocks 2 and the sliding rods 12, the movement process of the clamping blocks 2 is more stable. Subsequently, insert the two plug posts 3 into the corresponding slots 10. After that, release the clamping blocks 2. The elongation of the springs 11 drives the clamping blocks 2 to slide into the corresponding T-shaped sliding grooves 5, so that the clamping blocks on the clamping blocks 2 are clamped into the corresponding slots of the plug posts 3, thereby clamping the plug posts 3 on the counterweight 1 to prevent the plug posts 3 from disengaging from the counterweight 1 due to external force factors and reducing the protection fence effect. And at this time, the support block 9 and the universal wheels at its bottom end are still received in the receiving groove 14.

[0041] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can also be made without departing from the purpose of the present invention.
