Description

Technical Field

[0001] The utility model relates to the technical field of safety belts, in particular to a safety belt for high-altitude operations. Background Art

[0002] The safety belt for high-altitude use includes a leg-binding type, and the leg-binding part is a cloth belt. In order to make the cloth belt adapt to the thigh dimension of the wearer and better bind to the thigh, a figure-eight connecting ring is connected to one end of the cloth belt, and the other end of the cloth belt is inserted and wound around the connecting ring, so that the long cloth belt forms an annular cloth belt through the connecting ring, and then is connected to a vest-shaped cloth belt worn on the back through another cloth belt to form an integrated safety belt for high-altitude operations.

[0003] The inventor found that the following problems in the prior art were not well solved during the implementation of this solution: One end of the cloth belt is sleeved with one end of the figure-eight ring and sewn together with a thread, which is equivalent to forming a fixed connection, while the other end is directly wound around the other end of the figure-eight ring, and the limiting effect is achieved through the roughness of its outer wall and the tightening force. This connection is not completely fixed, and the figure-eight ring is basically exposed outside. When the operator wears the safety belt and is working, there will inevitably be oil stains. Once the oil stains contact the figure-eight ring, the wound end will slip. The originally tightened cloth belt will slip from the tight wound state and become a loose wound state, which will cause panic among the wearers and pose a great safety hazard. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a safety belt for high-altitude operations, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A safety belt for high-altitude operations includes a first box cover, one end of the first box cover is rotatably connected to a second box cover, a connecting ring is embedded in the first box cover, guide grooves one are opened at both ends of the side where the first box cover and the second box cover are close to each other, teeth are fixed at both ends of the first box cover far from the connection with the second box cover, pressure grooves are opened on the side walls of the teeth, L-shaped grooves are opened at the positions of the teeth on the second box cover, sliders are slidably connected inside the L-shaped grooves, insertion blocks are fixed at one ends of the sliders, springs are fixed at the other ends of the sliders, a soft rubber box is sleeved on the outer wall of the first box cover, a plurality of soft rubber boxes are fixed at the positions of the first box cover inside the connecting ring, the soft rubber boxes respectively penetrate through the connecting ring, an arc-shaped seat is fixed at the inner top end of the connecting ring near the teeth on the second box cover, and a plurality of internal teeth are arranged on the inner wall of the arc-shaped seat.

[0007] Preferably, one end of the spring away from the slider is fixedly connected to the inner wall of one side of the L-shaped groove away from the insertion block.

[0013] 1. The connecting ring is located inside between the first box cover and the second box cover. The end parts of the cloth belt are respectively connected to both ends of the connecting ring through the guiding grooves I. The connecting ring is formed into a covering box by the first box cover and the second box cover, avoiding its direct contact with the external oil stain, further reducing the potential safety hazard of the limit becoming loose after slipping. When the first box cover and the second box cover are closed, the teeth will be inserted deep into the inside of the L-shaped groove, and the insertion block at one end of the slider will be inserted into the inside of the pressing groove through the tension of the spring, forming the locking effect after the first box cover and the second box cover are closed, so that the covering box can stably wrap and cover the connecting ring.

[0014] 2. After the first box cover and the second box cover are closed and locked, the arc-shaped seat inside the second box cover will press on the outer wall of the cloth belt wound around the connecting ring and form extrusion and clamping on it, providing a stable limiting effect. The inner teeth contained in the inner wall of the arc-shaped seat can tightly press on the cloth belt, increasing the stability of the limit, so that the cloth belt of the safety belt leg strap can be more stably tied to the thigh.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figures 1-5 shown, a safety belt for working at height includes a first box cover 1. One end of the first box cover 1 is rotatably connected to a second box cover 2. A connecting ring 3 is embedded in the interior of the first box cover 1. First guiding grooves 14 are respectively formed at both ends of the side of the first box cover 1 close to the second box cover 2. Tooth 4 is fixed at both ends of the first box cover 1 far from the connection with the second box cover 2. Pressing grooves 5 are respectively formed on the side walls of the tooth 4. L-shaped grooves 6 are respectively formed at the positions of the second box cover 2 corresponding to the tooth 4. Sliders 7 are respectively slidably connected inside the L-shaped grooves 6. Inserting blocks 8 are respectively fixed at one ends of the sliders 7. Springs 9 are respectively fixed at the other ends of the sliders 7. A soft rubber box 15 is sleeved on the outer wall of the first box cover 1. A plurality of soft rubber boxes 15 are respectively fixed at the positions of the first box cover 1 inside the connecting ring 3. The soft rubber boxes 15 respectively penetrate through the connecting ring 3. An arc seat 12 is fixed at the inner top end of the second box cover 2 at the end of the connecting ring 3 close to the tooth 4. A plurality of internal teeth 13 are arranged on the inner wall of the arc seat 12.

[0023] Specifically, the ends of the springs 9 far from the sliders 7 are respectively fixed to the inner walls of the sides of the L-shaped grooves 6 far from the inserting blocks 8.

[0024] Specifically, the teeth 4 are respectively inserted into the L-shaped grooves 6 with matching positions, and the ends of the inserting blocks 8 far from the sliders 7 are respectively inserted into the pressing grooves 5, so that the first box cover 1 and the second box cover 2 have a limiting effect after being closed.

[0025] Specifically, traction grooves 10 are respectively formed on the side walls of the L-shaped grooves 6 away from each other of the second box cover 2. Traction buttons 11 are respectively inserted through the interiors of the traction grooves 10. The ends of the traction buttons 11 passing through the traction grooves 10 are respectively fixedly connected to the sides of the sliders 7 close to each other. The sliding of the traction buttons 11 can drive the inserting blocks 8 at one ends of the sliders 7 to be withdrawn from the pressing grooves 5, and then the second box cover 2 can be opened by rotation.

[0026] Specifically, the inner wall of the soft rubber box 15 is coated with glue, and the inner wall of the soft rubber box 15 is bonded to the first box cover 1 through the glue. The soft rubber box 15 can provide soft protection for the first box cover 1, avoiding the discomfort caused by the contact between the relatively hard first box cover 1 and the thigh during wearing.

[0027] Specifically, guiding grooves II 16 are drilled at both ends of the soft rubber box 15, and the positions of the guiding grooves II 16 respectively match the positions of the guiding grooves I 14 at both ends of the first box cover 1, facilitating the insertion of the cloth belt.

[0028] Working principle: The connecting ring 3 is located inside between the first box cover 1 and the second box cover 2. The end parts of the cloth belt are respectively connected to both ends of the connecting ring 3 through the guiding grooves I 14. The connecting ring 3 is covered by the first box cover 1 and the second box cover 2 to avoid its direct contact with external oil stains, further reducing the safety hazard of loosening of the limit after slipping. When the first box cover 1 and the second box cover 2 are closed, the tooth teeth 4 will insert deep into the inside of the L-shaped groove 6, and the insertion block 8 at one end of the slider 7 will insert into the inside of the pressing groove 5 due to the tension of the spring 9, forming a locking effect after the first box cover 1 and the second box cover 2 are closed. Thus, the covering box can stably wrap and cover the connecting ring 3. After the first box cover 1 and the second box cover 2 are closed and locked, the arc-shaped seat 12 inside the second box cover 2 will press on the outer wall of the cloth belt wound around the connecting ring 3 and clamp it, providing a stable limiting effect. The inner teeth 13 contained in the inner wall of the arc-shaped seat 12 can tightly press on the cloth belt, increasing the stability of the limit, so that the cloth belt of the safety belt leg strap can be more stably tied to the thigh.
