Description

Technical Field

[0001] The utility model relates to the technical field of safety belts, in particular to a semi-garment type safety belt. Background Art

[0002] A semi-costume safety belt is a half-body wearable safety belt. When working at high altitude or dangerous locations (such as working on a ship), a semi-costume safety belt needs to be worn to ensure the personal safety of construction workers.

[0003] To improve the safety of construction workers wearing safety belts, existing technologies have made numerous improvements to semi-garment safety belts. For example, patent publication number CN217015122U discloses a new reflective safety belt, comprising a waist belt with two shoulder straps and a chest strap between them; a wear-resistant reinforcement belt, attached to the shoulder belt surface, with a waist belt buckle mounted on the outer surface of the wear-resistant reinforcement belt, and a drawstring bolted to the waist belt buckle; and three sets of reflective webbing, one on each shoulder strap, chest strap, and waist belt surface. The beneficial effects include: the high reflective coefficient of the reflective webbing effectively enhances the safety belt's warning effect, making it easier for other personnel to detect and identify it, significantly reducing safety risks during cross-operation and facilitating supervision and inspection of safety belts. This semi-garment safety belt, with its own reflective warning color, combines both warning and fall prevention functions, significantly improving worker comfort, significantly reducing management complexity, and significantly enhancing the safety of high-altitude construction projects.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative documents, reflective warning colors are set to improve the recognition of semi-clothing safety belts, which makes it easier to supervise construction workers and remind them to wear safety belts. However, in the current situation, when construction workers are working on the deck of a ship, due to the large area of the deck, the construction range of each construction worker is large. As the length of the pull rope in the above-mentioned comparative documents is limited, when the position of the clamp and the buckle is restricted, the working range of the construction workers wearing the safety belt will be limited. If they want to expand the working range, they need to remove the clamp and the buckle and find a new fixed position, which affects the construction efficiency of the construction workers. Therefore, this field urgently needs to make improvements to the semi-clothing safety belt to solve the defects of the existing technology. Utility Model Content

[0006] In view of the deficiencies of the existing technology, the utility model provides a semi-garment type safety belt, which can adjust the length of the safety rope, thereby adjusting the construction range of the construction workers, making it convenient for the construction workers to carry out construction.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a semi-clothing safety belt, comprising a waist belt, wherein the waist belt is provided with two adjustable shoulder straps, a front chest adjustment strap and a back fixing strap are provided between the two shoulder straps, a carrying frame is provided on the back fixing strap, a rotating shaft is rotatably connected to the carrying frame, a safety rope is wrapped around the side of the rotating shaft, one end of the safety rope is fixedly installed to the side of the rotating shaft, a side of the carrying frame away from the back fixing strap is provided with a clearance opening for the safety rope to fit, the end of the rotating shaft passes through the carrying frame and extends to the outside, a limiting unit is provided at the end of the carrying frame, the limiting unit is used to limit and fix the position of the rotating shaft, and a torsion spring is installed between the rotating shaft and the carrying frame.

[0008] Preferably, the limiting unit includes two limiting columns symmetrically arranged at the ends of the supporting frame, a movable plate is sleeved between the sides of the two limiting columns, a polygonal limiting hole is opened through the movable plate, and a limiting platform adapted to the limiting hole is opened on the side of the end of the rotating shaft, and a baffle is provided on the end of the two limiting columns away from the supporting frame, and a spring sleeved on the side of the limiting column is provided between the baffle and the movable plate.

[0009] Preferably, both ends of the rotating shaft pass through both ends of the carrying frame, and mounting holes adapted to the limiting columns are opened at both ends of the carrying frame, and one end of the limiting column is threadedly connected to the mounting hole.

[0010] Preferably, the opposite side walls in the clearance opening are rotatably connected to guide rods, and the distance between the two guide rods is adapted to the safety rope.

[0011] Preferably, a mounting bolt passes through the baffle, and one end of the mounting bolt is threadedly connected to the end of the limiting column.

[0012] Preferably, mounting blocks are provided on opposite sides of the carrying frame, and the mounting blocks are connected to the back fixing belts.

[0013] Preferably, the movable plate is rotatably connected to a handle on the side.

[0014] In view of the shortcomings of the existing technology, the present invention provides a semi-garment type safety belt, which overcomes the shortcomings of the existing technology. The beneficial effects of the present invention are:

[0015] 1. In the present invention, a buckle is fixedly connected to one end of the safety rope away from the bearing frame. When in use, the buckle is snapped into a specified position. If it is necessary to adjust the construction range of the construction workers, the limit unit on the rotating shaft is released, and the construction workers move to a position away from the buckle. At this time, the safety rope is pulled out from the clearance position. When the length of the safety rope pulled out of the bearing frame is sufficient for the construction workers to work, the limiting unit is used to limit the rotating shaft, and the length of the safety rope can be adjusted, thereby realizing the adjustment of the construction range of the construction workers, making it convenient for the construction workers to carry out construction.

[0016] 2. In the present invention, one end of the limit column is threadedly connected to the mounting hole, which can be adjusted according to the construction workers' habits, thereby improving the applicability of the overall device. The two guide rods prevent the safety rope from being scratched by the gap when it slides out, thereby increasing the service life of the safety rope.

[0017] 3. In the present invention, the baffle and the limit column are detachably connected, and springs with different elastic coefficients can be selected according to actual conditions. If the semi-garment type safety belt is damaged in the later stage, the bearing frame can be removed and sewn onto a new semi-garment type safety belt through the installation block to continue using it, thereby reducing the cost of use.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1

[0027] See also Figure 1-Figure 4 A semi-garment safety belt comprises a waist belt 1, two adjustable shoulder straps 2 are provided on the waist belt 1, a front chest adjustment belt 3 and a back fixing belt 4 are provided between the two shoulder straps 2, a carrying frame 5 is provided on the back fixing belt 4, a rotating shaft 6 is rotatably connected to the carrying frame 5, a safety rope 7 is wrapped around the side of the rotating shaft 6, one end of the safety rope 7 is fixedly installed with the side of the rotating shaft 6, a clearance opening 8 adapted for the safety rope 7 is opened on the side of the carrying frame 5 away from the back fixing belt 4, the end of the rotating shaft 6 passes through the carrying frame 5 and extends to the outside, a limiting unit 9 is provided at the end of the carrying frame 5, and the limiting unit Element 9 is used to limit and fix the position of the rotating shaft 6. A torsion spring is installed between the rotating shaft 6 and the supporting frame 5. The limiting unit 9 includes two limiting columns 10 symmetrically arranged at the ends of the supporting frame 5. A movable plate 11 is sleeved between the sides of the two limiting columns 10. A polygonal limiting hole 12 is opened through the movable plate 11. A limiting platform 13 adapted to the limiting hole 12 is opened on the side of the end of the rotating shaft 6. A baffle 14 is provided on the end of the two limiting columns 10 away from the supporting frame 5. A spring 15 sleeved on the side of the limiting column 10 is provided between the baffle 14 and the movable plate 11.

[0028] The specific implementation method of this embodiment: the waist belt 1 is set on the waist of the construction worker, the shoulder strap 2 can be adjusted in length and put on the shoulders of the construction worker, and the front chest adjustment belt 3 is connected and adjusted. If necessary, the thigh fixing belt can be connected to the lower part of the waist belt 1, and the end of the safety rope 7 away from the supporting frame 5 is fixedly connected with a buckle. When in use, the buckle is snapped into the specified position. If it is necessary to adjust the construction range of the construction worker, the movable plate 11 is pulled by hand, and the movable plate 11 moves away from the supporting frame 5. At this time, the spring 15 is compressed, and the baffle 14 is used to block the movable plate 11. When the limiting hole 12 on the movable plate 11 is out of the position of the limiting platform 13, the construction worker moves to a position away from the buckle. At this time, the safety rope 7 is pulled out from the position of the yield mouth 8. When the length of the safety rope 7 pulled out of the supporting frame 5 is sufficient for the construction worker to work, the movable plate is released. 11. At this time, the tension of the spring 15 pushes the movable plate 11 close to the supporting frame 5, and the limiting hole 12 is clamped on the side of the limiting platform 13 to limit the rotating shaft 6. Even if the limiting hole 12 is not clamped on the limiting platform 13, when the construction personnel move again, it will drive the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, the limiting hole 12 can match and clamp with the limiting platform 13. When it is necessary to shorten the safety rope 7 to expose the supporting frame 5, the movable plate 11 is also pulled to disengage the limiting hole 12 from the limiting platform 13, and the construction personnel move in the direction of the buckle. At this time, the torsion spring drives the rotating shaft 6 to rotate, and then the safety rope 7 is received into the supporting frame 5. The length of the safety rope 7 can be adjusted, thereby realizing the adjustment of the construction range of the construction personnel, which is convenient for the construction personnel to carry out construction and operation. The torsion spring is an existing well-known technology and will not be described in detail here.

[0029] Example 2

[0031] The specific implementation method in this embodiment: the direction of installation of the limit column 10 can be selected according to the working habits of the construction personnel. If the construction personnel are accustomed to using their left hand to thread the limit column 10 into the installation hole 16 at the left end of the supporting frame 5, the construction personnel are accustomed to using their right hand to install the limit column 10 at the right end of the supporting frame 5. It can be adjusted by the construction personnel according to their habits to improve the applicability of the overall device. The two guide rods 17 prevent the safety rope 7 from being scratched by the yield mouth 8 when it slides out, thereby increasing the service life of the safety rope 7.

[0033] See also Figure 1-Figure 3 This embodiment includes all the above embodiments, which further includes: a mounting bolt 18 passes through the baffle 14, one end of the mounting bolt 18 is threadedly connected to the end of the limiting column 10, and mounting blocks 19 are provided on the opposite sides of the supporting frame 5, the mounting blocks 19 are connected to the back fixing belt 4, and a handle 20 is rotatably connected to the opposite side of the movable plate 11.

[0034] The specific implementation method in this embodiment is: the baffle 14 is penetrated by the installation bolt 18 and its end is threadedly connected to the threaded hole opened at the end of the limit column 10. The spring 15 with different elastic coefficients can be selected according to the actual situation. The mounting block 19 and the back fixing belt 4 can be connected by sewing. If the semi-clothing safety belt is damaged in the later stage, the supporting frame 5 can be removed and sewn on the new semi-clothing safety belt through the mounting block 19 to continue to use it, thereby reducing the cost of use.
