[0020] See also Figure 1-3 The utility model provides an embodiment: a high-rise building construction anti-fall protection device, including a fixing base 1, a locking block 2 is fixedly installed on the upper surface of the fixing base 1, a primary movable groove 3 is opened inside one side of the locking block 2, and a secondary movable groove 4 is opened inside the other side of the locking block 2. An inner screw 5 is rotatably installed inside the primary movable groove 3 through a bearing, and a locking column 6 is sleeved on the outer side of the inner screw 5. The locking column 6 is threadedly connected to the inner screw 5. The locking column 6 adopts an inverted "U"-shaped structure design, and the end of the locking column 6 away from the inner screw 5 is vertically aligned with the secondary movable groove 4;

[0021] With this structural design, when the inner screw 5 rotates clockwise, the locking post 6 threadedly connected thereto moves upward along the inner screw 5, thereby allowing the other end of the locking post 6 to move out of the secondary movable groove 4. At this time, an opening appears between the locking post 6 and the locking block 2, and the anti-fall protection device of the utility model can be mounted on the guardrail of the lifting platform through the provided opening;

[0022] After the anti-fall protection device is sleeved on the guardrail of the lifting platform, the inner stud 5 can be manually rotated counterclockwise. When the inner stud 5 is rotated counterclockwise, the locking column 6 on it will move downward along the inner screw 5. At this time, the other end of the locking column 6 is inserted into the secondary movable groove 4. When one end of the locking column 6 reaches the bottom of the secondary movable groove 4, the inner screw 5 cannot rotate counterclockwise. At this time, the locking column 6 and the locking block 2 are closed, so that the utility model can be closed and locked on the guardrail of the lifting platform.

[0023] In order to provide secondary locking protection for the locking column 6 to prevent it from opening, the two ends of the locking column 6 are slidably connected to the primary movable groove 3 and the secondary movable groove 4 respectively. A primary locking hole 7 is opened on one side of the locking column 6, and a secondary locking hole 8 is opened on the side of the secondary movable groove 4. The primary locking hole 7 and the secondary locking hole 8 have the same aperture, and both the primary locking hole 7 and the secondary locking hole 8 are threaded holes.

[0024] In order to lock the lock pillar 6 after closing, a locking screw 9 adapted to the primary locking hole 7 and the secondary locking hole 8 is provided between them, and a secondary knob is fixedly installed on one end of the locking screw 9;

[0025] When the locking post 6 is in operation, the locking pin 9 is rotated in the clockwise direction to lock the locking post 6 and the locking block 2, thereby effectively preventing the locking post 6 from opening. The locking pin 9 has the function of locking and fixing and resisting external forces, and effectively improves the anti-fall locking protection effect of the utility model. When in use, the locking pin 9 must be removed first, and the locked state can be released by rotating the inner screw 5 clockwise. The locking pin 9 has a double thread locking protection effect, which effectively improves the performance and safety of use.

[0026] In this embodiment, in order to facilitate manual rotation of the inner screw 5, please refer to the attached manual for details. Figure 3 As shown, the bottom end of the inner screw 5 is fixedly connected to a connecting rod, and the bottom end of the connecting rod passes through the locking block 2 and the lower fixing seat 1 and is fixedly connected to a knob 10.

[0027] In this embodiment, in order to facilitate the connection of the fixing base 1 to the external anti-fall rope, a lower fixing ring 11 is fixedly installed on the lower surface of the fixing base 1. When in use, one end of the rope is fixed to the lower fixing ring 11, and the other end of the rope is tied around the waist of the staff, thereby achieving a certain anti-fall protection effect.

[0028] Working principle: The lower surface of the fixing base 1 of the utility model is fixedly mounted with a lower fixing ring 11. When in use, one end of the rope is fixed to the lower fixing ring 11, and the other end of the rope is tied around the waist of the worker, thereby achieving a certain anti-fall protection effect. The length of the anti-fall rope can be dynamically selected according to actual use requirements;

[0029] When the rope is fixed, the staff can manually rotate the inner screw 5 clockwise through the knob 10. When the inner screw 5 rotates clockwise, the locking column 6 threadedly connected thereto will move upward along the inner screw 5, so that the other end of the locking column 6 can be moved upward out of the secondary movable groove 4. At this time, an opening appears between the locking column 6 and the locking block 2, and the anti-fall protection device of the utility model can be placed on the guardrail of the lifting platform through the provided opening;

[0030] After the anti-fall protection device is sleeved on the guardrail of the lifting platform, the inner stud 5 can be manually rotated counterclockwise. When the inner stud 5 is rotated counterclockwise, the locking column 6 on it will move downward along the inner screw 5. At this time, the other end of the locking column 6 is inserted into the secondary movable groove 4. When one end of the locking column 6 reaches the bottom of the secondary movable groove 4, the inner screw 5 cannot rotate counterclockwise. At this time, the locking column 6 and the locking block 2 are closed, so that the utility model can be closed and locked on the guardrail of the lifting platform.

[0031] When the bottom of one end of the locking column 6 contacts the bottom surface of the secondary movable groove 4, the primary locking hole 7 and the secondary locking hole 8 are horizontally aligned. The staff can rotatably install the locking screw 9 in the primary locking hole 7 and the secondary locking hole 8, so that the locking column 6 and the locking block 2 can be threadedly locked by the locking screw 9 screwed in, thereby effectively preventing the locking column 6 from being opened, having a good locking fixation and resistance to external forces, and effectively improving the locking protection effect of the utility model against falling. When in use, the locking screw 9 must be removed first, and the locked state can be released by rotating the inner screw 5 clockwise, which has a double thread locking protection effect and effectively improves the performance and safety of use.

[0032] By adopting the structural design of the utility model, the worker can be locked on the lifting platform through the anti-fall protection device and the rope of the utility model. When an accidental fall occurs, the utility model can be used in conjunction with the rope to lock and pull the worker to prevent him from continuing to fall, which has a good active anti-fall protection effect, can effectively improve the anti-fall protection characteristics for the worker, improve the safety of the worker when performing installation work at height, reduce safety hazards, and improve the work safety factor;

[0033] The present invention can be conveniently locked and opened by manual rotation, and the locking and closing operations can be performed conveniently. It is easy to use, has good structural performance, is stable, has good locking fixation and the function of resisting external forces, and effectively improves the locking protection effect of the present invention against falling. When in use, the locking screw pin 9 must be removed first, and the locked state can be released by rotating the inner screw 5 clockwise, which has a double thread locking protection effect, effectively improving the performance and safety of the present invention. It has the technical characteristics of double insurance protection, is safer to use, and has a simple overall structure and low manufacturing cost, making it suitable for popularization and use.
