Description

Technical Field

[0001] The utility model relates to the technical field of column form fasteners, in particular to a large-load fastener that can be automatically locked. Background Art

[0002] Construction is a production activity in which people use various building materials and mechanical equipment to build various building products in a certain space and time according to a specific design blueprint. At this stage, in the process of construction, column molds need to be installed to build columns, and column molds need to be fixed with fasteners.

[0003] Publication No. CN220504514U discloses a construction column form fastener, which moves by rotating a threaded tube, the threaded tube drives the screw to move, the screw drives the frame to move, and then the frame drives the auxiliary rod to slide on the inner wall of the circular hole. The auxiliary rod can limit the frame to prevent the frame from offsetting when moving, thereby improving the stability of the frame. The auxiliary sleeve can protect the auxiliary rod, the protective sleeve can protect the threaded tube, and the anti-slip pattern can increase the friction between the hand and the protective sleeve. By setting the auxiliary structure, the effect of convenient and quick use and contraction of the frame is achieved. However, the patent still has the following problems in actual use:

[0004] The device drives the frame to move through the screw rod, and then the frame drives the auxiliary rod to slide on the inner wall of the circular hole. The auxiliary rod can limit the frame to prevent the frame from shifting when moving, thereby improving the stability of the frame. Construction in an open air environment, especially high column molds, are easily affected by wind. Strong winds may cause the column molds to shake or shift, causing the fasteners to bear additional loads. Since the screw rod of the device is not provided with a limiting structure, when the column mold shakes, the screw rod may be affected by the load and rotate, thereby affecting the fixing effect of the column mold and bringing danger to the staff when using it.

[0005] A self-locking heavy-load fastener is proposed to solve the above problems. Utility Model Content

The auxiliary rod can limit the frame to avoid the frame from shifting when moving, thereby improving the stability of the frame. Construction in an open air environment, especially high column molds, is easily affected by wind. Strong winds may cause the column molds to shake or shift, causing the fasteners to bear additional loads. Since the screw of the device is not provided with a limiting structure, when the column mold shakes, the screw may be affected by the load and rotate, thereby affecting the fixing effect of the column mold and bringing danger to the staff when using it.

[0007] To achieve the above object, the utility model provides the following technical solutions: an automatically locked large-load fastener, comprising a frame, mounting rods are symmetrically arranged between two sides of the frame, and mounting rings are installed on the outside of the mounting rods; adjustment mechanisms are symmetrically arranged between the frames, and support mechanisms are arranged at the tops of the frames;

[0014] Preferably, two sides of the tooth plate are meshingly connected with the gears.

[0015] Compared with the prior art, the beneficial effects of the utility model are: this is a large-load fastener that can be automatically locked, and its specific contents are as follows: through the reset property of the first telescopic spring, the tooth block is meshed and connected with the outer spiral teeth of the bidirectional screw, so that the adjusted bidirectional screw can be fixed and limited, and can effectively avoid the shaking of the column mold caused by external force factors, thereby reducing the additional load on the frame, thereby improving the fixing effect of the column mold, and increasing the safety of the staff when using it. Through the design of the support rod, the column mold is prevented from moving or deforming during concrete pouring. They provide necessary support for the column mold, ensuring that the column mold remains stable when bearing the weight of concrete and pouring pressure, further reducing the load resistance of the frame, and facilitating the installation and disassembly of the column mold by the staff.

[0016] 1. By rotating the bidirectional screw rod, the frames can move relative to each other. At this time, the limit rod and the frame are slidably connected, so as to fix column molds of various specifications. Then, the moving plate is driven to move by pulling the operating rod. The movement of the moving plate squeezes the first telescopic spring. At this time, the first telescopic spring contracts. By loosening the operating rod, the first telescopic spring is reset to make the tooth block mesh with the outer spiral teeth of the bidirectional screw rod, so that the adjusted bidirectional screw rod can be fixed and limited, which can effectively prevent the column mold from shaking due to external force factors, thereby reducing the additional load on the frame, thereby improving the fixing effect of the column mold and increasing the safety of the staff during use. When the limit rod is moving, the positioning rod is squeezed by the limit rod, so that the second telescopic spring contracts. When the limit rod is adjusted, the positioning rod is fixed to the slot through the reset of the second telescopic spring, so as to achieve a preliminary limiting effect, so that the automatic locking effect can be achieved after the adjustment between the frames is completed, and the stability between the frame and the column mold is further improved.

[0017] 2. By plugging the socket into the mounting base, the support rod fits against the outside of the column formwork, and then the gear is driven to rotate by pushing the toothed plate. The rotation of the gear drives the rotation of the rotating plate. The rotation of the rotating plate causes the card ball to engage with the card block, thereby achieving the effect of quickly installing and removing the support rod. The design of the support rod prevents the column formwork from moving or deforming during concrete pouring. They provide necessary support for the column formwork, ensuring that the column formwork remains stable when bearing the weight of concrete and pouring pressure, further reducing the load resistance of the frame, and the support rod is designed to be quick-installed, so that it is easy for the staff to install and disassemble it, which brings convenience to the staff when using it.
