DETAILED DESCRIPTION

[0022] 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.

[0023] Example: See Figures 1 to 6According to an embodiment of the utility model, a technical solution is provided: a sunken floor slab hanging formwork support, comprising a support rod 1, and also comprising a load-bearing rod 2, a first end of which is fixed with a limiting rod 3, a second end surface of the load-bearing rod 2 is provided with a notch 5, and a limiting groove 6 connected to the notch 5 is provided at the top of the load-bearing rod 2 along its length direction, the support rod 1 is used to support the load-bearing rod 2; a moving rod 7 is slidably arranged in the notch 5, a limiting rod 2 4 is fixed on the moving rod 7, and the limiting rod 2 4 is slidably arranged in the limiting groove 6; and a locking mechanism 8, the locking mechanism 8 comprises a moving block 9, a spring 10, a guide rod 11, a pressing portion 12 and a column 13, a plurality of locking grooves 14 are spaced apart on the moving rod 7 along its length direction, the guide rod 11 is fixed in the locking groove 14, and the moving block 9 is movably arranged in the notch 5. The locking groove 14, the moving block 9 is movably penetrated by the guide rod 11, the spring 10 is sleeved on the guide rod 11, the two ends of the spring 10 are respectively fixed on the moving rod 7 and the moving block 9, the column 13 is fixed on the bearing rod 2, the end surface of the column 13 is provided with a through opening 15 connected with the notch 5, the pressing part 12 is movably arranged at the through opening 15, and limiting blocks 16 are fixed on both sides of the pressing part 12, and limiting grooves 17 suitable for the movement of the limiting blocks 16 are provided on the inner wall of the through opening 15, the pressing part 12 is suitable for moving in and out of the locking groove 14, and a guide groove 18 suitable for the movably inserted guide rod 11 is provided on the pressing part 12, and a driving member 19 is used to drive the pressing part 12 to approach the locking groove 14.

[0024] When the user needs to perform a formwork hanging operation using the sunken floor formwork support with the above structure, first, according to the width of the formwork to be supported, adjust the position of the moving rod 7 in the slot 5 until the spacing between the limit rod 1 3 and the limit rod 2 4 is suitable for placing the formwork to be supported. At this time, the pressing part 12 is driven by the driving member 19 to move from the outside of the through opening 15 to the inside until the pressing part 12 contacts the moving block 9. During the movement of the pressing part 12, the limiting block 16 thereon will slide along the limiting groove 17. At the same time, the guide groove 18 on the pressing part 12 will also be aligned with the guide rod 11 and inserted by the guide rod 11. As the pressing part 12 moves further, it will compress the spring 10, so that the moving block 9 moves inward along the locking groove 14 under the guidance of the guide rod 11. When the pressing part 12 completely enters the locking groove 14, the pressing part 12 is simultaneously in the locking groove 14 and the through-port 15, thereby fixing the moving rod 7 relative to the bearing rod 2 to limit the sliding of the moving rod 7 in the notch 5, thereby continuously maintaining the spacing between the limiting rod 1 3 and the limiting rod 2 4. On the contrary, when the user does not need to fix the moving rod 7 on the bearing rod 2, the pressing part 12 is withdrawn from the locking groove 14 by reversely operating the driving member 19, and the spring 10 releases its elastic force, pushing the moving block 9 to move outward along the guide rod 11 until the pressing part 12 is completely disengaged from the locking groove 14, at which time, the pressing part 12 is completely in the through-port 15. At this point, the user can easily slide the moving rod 7, and the entire adjustment process is simple and efficient, while also improving the scope of use of the device.

[0025] In order to drive the pressing part 12 to enter the locking groove 14, in this embodiment, the driving member 19 includes a driving sleeve 20, and a storage port 21 is provided on the first end face of the driving sleeve 20, and an abutment column 22 is rotatably provided in the storage port 21, and the inner peripheral side wall of the storage port 21 is threadedly connected to the outer peripheral side wall of the column 13; when the user needs to drive the pressing part 12 to enter the locking groove 14, the driving sleeve 20 is rotated to gradually move the driving sleeve 20 along the thread of the column 13, and because the driving sleeve 20 can generate a certain axial force when rotating on the column 13, this force will be transmitted to the abutment column 22, and then the abutment column 22 pushes the pressing part 12 to gradually enter the locking groove 14.

[0026] In order to facilitate the user to rotate the drive sleeve 20, in this embodiment, a screw plate 23 is fixed to the second end surface of the drive sleeve 20; when the user needs to rotate the drive sleeve 20, the screw plate 23 will provide the user with a fulcrum for rotating the drive sleeve 20, so that the user can rotate the drive sleeve 20.

[0027] In order to improve the stability of the limit rod 24, in the present embodiment, a reinforcement rod 24 is provided between the limit rod 24 and the movable rod 7, and the two ends of the reinforcement rod 24 are respectively fixed on the free end of the limit rod 24 and the movable rod 7, and the reinforcement rod 24 is suitable for moving in and out of the limit groove 6; the two ends of the reinforcement rod 24 are respectively firmly connected to the free end of the limit rod 24 and the movable rod 7, forming a stable triangular support structure, thereby improving the stability of the limit rod 24.

[0028] In order to prevent the hanging mold from sliding, in this embodiment, a friction plate 25 is provided on the limiting rod 24; when the hanging mold is placed on the bearing rod 2, the friction plate 25 can effectively prevent the hanging mold from sliding in the horizontal direction, thereby improving the stability of the hanging mold when being supported.

[0029] Working principle: When the user needs to perform a hanging mold operation, first, according to the width of the hanging mold to be supported, adjust the position of the moving rod 7 in the slot 5 until the spacing between the limit rod 1 3 and the limit rod 2 4 is suitable for placing the hanging mold to be supported. At this time, by rotating the drive sleeve 20, the drive sleeve 20 is gradually moved along the thread of the column 13. Since the drive sleeve 20 can generate a certain axial force when rotating on the column 13, this force will be transmitted to the abutment column 22, and then the abutment column 22 will gradually push the pressing part 12 until the pressing part 12 contacts the moving block 9. During the movement of the pressing part 12, the limiting block 16 thereon will slide along the limiting groove 17. At the same time, the guide groove 18 on the pressing part 12 will also be aligned with the guide rod 11 and inserted by the guide rod 11. As the pressing part 12 moves further, it compresses the spring 10, so that the moving block 9 moves inward along the locking groove 14 under the guidance of the guide rod 11. When the pressing part 12 completely enters the locking groove 14, the pressing part 12 is simultaneously in the locking groove 14 and the through-hole 15, thereby fixing the moving rod 7 and the bearing rod 2 relatively to limit the sliding of the moving rod 7 in the notch 5, thereby continuously maintaining the spacing between the limiting rod 1 3 and the limiting rod 2 4. The whole adjustment process is simple and efficient, and the use range of the device is also improved. In order to facilitate the user to rotate the drive sleeve 20, when When the user needs to rotate the drive sleeve 20, the screw plate 23 will provide the user with a fulcrum for rotating the drive sleeve 20, so that the user can rotate the drive sleeve 20; in order to improve the stability of the limit rod 24, the two ends of the reinforcement rod 24 are respectively firmly connected to the free end of the limit rod 24 and the movable rod 7, forming a stable triangular support structure, thereby improving the stability of the limit rod 24; in order to prevent the hanging mold from sliding, when the hanging mold is placed on the load-bearing rod 2, the friction-increasing plate 25 can effectively prevent the hanging mold from sliding in the horizontal direction, thereby improving the stability of the hanging mold when being supported.
