DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the 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 of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention.

[0024] This embodiment proposes a kind of autoclaved aerated concrete board using a drill rod, such as Figures 1 to 4As shown, it includes a drill rod body 1 and a concrete slab body 2, the drill rod body 1 is inserted into the concrete slab body 2, and a plug hole 3 is opened inside the concrete slab body 2 to cooperate with the drill rod body 1, and a drill rod head 4 is welded and fixed to the bottom of the drill rod body 1. A placement groove 5 is opened inside the drill rod body 1 on the top surface of the drill rod head 4, and a connecting bracket 8 is symmetrically slidably sleeved inside the placement groove 5. The outsides of the two connecting brackets 8 are fixed with fixed blocks 9, and a pulling rod 6 is slidably inserted into the drill rod body 1 above the fixed block 9 to push the fixed block 9. The concrete slab body 2 is symmetrically provided with a fixing groove 14 that cooperates with the fixed block 9. The two fixing brackets are symmetrically provided with a fixing groove 14 that cooperates with the fixed block 9. The end of the block 9 extending to the outside of the drill rod body 1 is inserted into the fixing groove 14. When using the drill rod body 1, align the drill rod head 4 and insert it into the concrete slab 2, and align the fixed block 9 with the fixing groove 14. Press the pull rod 6 so that the pull rod 6 pushes the connecting support block 8, and the connecting support block 8 drives the fixed block 9 to be inserted into the fixing groove 14, so that the drill rod body 1 and the concrete slab 2 can be fixed. After the concrete slab 2 is moved, pull the pull rod 6 upward, and the fixed block 9 is pulled out of the fixing groove 14, so that the fixation between the drill rod body 1 and the concrete slab 2 is released, and the drill rod body 1 is pulled out from the inside of the concrete slab 2.

[0025] On the basis of the above scheme, the pulling rod 6 extends to one end outside the top of the drill rod body 1, and the limiting clamping plate 15 is symmetrically fixed on the top surface of the drill rod body 1. The limiting clamping sleeve 16 is symmetrically fixed on the top surface of the drill rod body 1. The opposite sides of the two limiting clamping sleeves 16 are provided with a slot that cooperates with the limiting clamping plate 15. When the pulling rod 6 pushes the push block 7 to move downward, the limiting clamping plate 15 is driven to move to fit the top surface of the drill rod body 1, and then the pulling rod 6 is turned left, and the limiting clamping plate 15 is rotated to the inside of the limiting clamping sleeve 16. The limiting clamping plate 15 is limited by the limiting clamping sleeve 16 to prevent the pulling rod 6 from popping out. The two limiting clamping plates 15 and the limiting clamping sleeve 16 are both set to cooperate with the drill rod The main body 1 and the pulling rod 6 are fan-shaped, and the arc length of each limit card plate 15 and the limit sleeve 16 is less than one-fourth of the arc length of the drill rod main body 1, ensuring that the limit card plate 15 can be rotated to be misaligned with the limit sleeve 16. A push block 7 is slidingly provided inside the placement groove 5 between the two connecting brackets 8. Both sides of the push block 7 are set to an inclined shape that cooperates with the connecting bracket 8 and the inner side of the top. The top surface of the push block 7 is rotatably connected to the bottom surface of the pulling rod 6 through a bearing. When the pulling rod 6 moves downward, the push block 7 is pushed downward. Under the inclined design on both sides, the connecting bracket 8 is pushed to both sides, and the tension spring 12 pushes the fixed card 9 into the fixed groove 14.

[0026] During the implementation of the above scheme, when the push block 7 moves to the top between the two connecting brackets 8, it is necessary to pull the fixed card block 9 back into the placement groove 5. Therefore, the two fixed card blocks 9 are slidably sleeved with a support slide 10. The opposite ends of the two support slides 10 are fixed on the fixed plate 11. The bottom surface of the fixed plate 11 is fixed to the bottom surface of the placement groove 5. The support slides 10 on both sides of the fixed plate 11 are sleeved with springs 12. The two ends of the spring 12 are respectively fixed on the fixed card block 9 and the fixed plate 11. The ends of the two fixed card blocks 9 away from the connecting bracket 8 are both set to an arc shape that cooperates with the outer surface of the drill rod body 1 The two fixed blocks 9 are provided with T-shaped slide grooves 13 on the opposite sides thereof, which cooperate with the support slide rod 10 and the spring 12. When the push block 7 pushes the connecting support block 8, the connecting support block 8 drives the fixed block 9 to move out of the drill rod body 1 and insert it into the fixed groove 14, while stretching the spring 12. When the push block 7 is pulled up to release the push on the connecting support block 8, the connecting support block 8 moves toward the inside of the placement groove 5 under the pull of the spring 12, and at the same time drives the fixed block 9 to move out of the fixed groove 14. At this time, the fixation of the drill rod body 1 and the concrete slab 2 is released, and the drill rod body 1 is pulled out from the inside of the concrete slab 2.

[0027] When the drill rod body 1 is pulled, after the fixed block 9 is inserted into the fixed groove 14, the drill rod body 1 is fixed to the concrete slab 2, resulting in the position of the auxiliary grip 17 restricted by the concrete slab 2. In order to facilitate the gripping of the auxiliary grip 17 and the application of force, a movable groove 19 is provided on the outer surface of the end of the drill rod body 1 away from the drill rod head 4. A rotating collar 18 is rotatably sleeved on the upper part of the movable groove 19. The auxiliary grip 17 is symmetrically fixed on the outer surface of the rotating collar 18. A fixed clamp 20 is threadedly sleeved on the movable groove 19 on the bottom surface of the rotating collar 18. The rotating collar 18 and the fixed clamp 20 are both arranged to be aligned with the movable groove 1 9 is a ring shape that matches the drill rod body 1. The outer diameters of the rotating collar 18 and the fixed clamping block 20 are equal to the outer diameter of the drill rod body 1. The lower part of the movable groove 19 is provided with a thread that matches the fixed clamping block 20. The outer surface of the auxiliary grip 17 is wrapped with a non-slip and shock-absorbing rubber sleeve. When the drill rod body 1 is pulled, the fixed clamping block 20 is rotated to release the clamping of the rotating collar 18 by the fixed clamping block 20. The rotating collar 18 can be rotated to drive the auxiliary grip 17 to rotate, and the gripping angle can be adjusted to facilitate the control of the drill rod body 1. After the rotation is completed, the fixed clamping block 20 is rotated to re-clamp the rotating collar 18.
