Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a three-point single-hook suspension safety belt. Background Art

[0002] A three-point seat belt, also known as a half-body seat belt, is a belt that secures only the upper body, with three points of contact (or parts) with the body: the waist and both shoulders. Its advantages are lightness, ease of donning, mobility, affordability, and practicality. Its disadvantages are lower safety, a single hook, and no cushioning.

[0003] Related technology (publication number: CN204319555U) discloses a three-point harness safety belt, the disclosed technical solution of which is that the three-point harness safety belt can be suitable for users of different body shapes, suitable for different occasions such as car seats or high-altitude operations, easy to wear, and has efficient protection capabilities.

[0004] In the above-mentioned disclosed technical solutions, the following problems were found in the relevant technologies: when a three-point safety belt is in operation, the top end of the lifting rope will be locked at a safe point through a hook. In the event of a fall during operation, protection is provided by the traction of the lifting rope. However, the gravitational potential energy generated during the fall is large. Under the premise that there is no buffer component on the lifting rope, the impact force on the operator's body is large. Experiments have shown that the human body can withstand an impact force of 12KN in a short period of time. When the impact force is large, it will cause damage to the human body. In this regard, we have proposed a new three-point single-hook suspension safety belt.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background technology section of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

In order to solve the fall protection problem existing in the above-mentioned prior art, this utility model provides a three-point single-hook suspension safety belt, which adopts a buffer rope structure combined with a rope anti-kink structure to improve the safety effect in the event of a fall. The specific technical solution is as follows:

[0007] A three-point single-hook suspension safety belt comprises a safety belt and a hook, a rope connector is provided at the back intersection of the safety belt, the disassembly end of the rope connector is provided with an anti-twist assembly, the free end of the anti-twist assembly is provided with one end of the belt rope, the other end of the belt rope is fixedly connected to a movable plug-in, one end of the hook rope is provided on the hook, the other end of the hook rope is fixedly connected to a socket sleeved on the outside of the movable plug-in, and a stepped buffer assembly is provided between the socket and the movable plug-in, and the adjacent ends of the belt rope and the hook rope are connected by an anti-slip extension rope.

[0008] In the above technical solution, the stepped buffer assembly includes wedge-shaped clamps arranged on both side walls of the movable plug-in, and wedge-shaped movable parts opposite to the wedge-shaped clamps are sequentially embedded on both sides of the inner wall of the socket.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The following is a combination of specific implementation cases and attached Figure 1-6 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0034] A three-point single-hook suspension safety belt comprises a safety belt 1 and a hook 3. A sling connector is provided at the intersection of the back of the safety belt 1. The three-point safety belt 1 has three points of contact with the human body, namely, the straps that contact the waist and both shoulders. To ensure the stability of the safety belt 1 after being worn, it is crossed at the waist after passing through the two shoulders. A sling connector that can be installed and removed from the sling is installed at the cross-connected waist position. The sling connector allows installation and removal between the safety belt 1 and the sling, making it more convenient to replace the sling.

[0035] The detachable end of the rope connector is equipped with an anti-twist assembly. The free end of the anti-twist assembly is connected to one end of the belt rope 2, while the other end of the belt rope 2 is fixedly connected to a movable insert 6. The anti-twist assembly is mounted on the detachable part of the rope connector to prevent the rope from rotating or kinking. This anti-twist assembly prevents the safety harness rope from rotating or kinking during a fall, thereby reducing the risk of hazard and ensuring safety during construction.

[0036] One end of a hook sling 4 is provided on the hook 3, and the other end of the hook sling 4 is fixedly connected to a socket 5 that is sleeved on the outside of the movable plug-in 6, and a stepped buffer assembly is provided between the socket 5 and the movable plug-in 6. One end of the belt sling 2 is fixedly connected to the free end of the anti-twist assembly, and the other end of the belt sling 2 is fixedly connected to the bottom end of the movable plug-in 6. One end of the hook sling 4 is fixedly mounted on the hook 3, and the other end of the hook sling 4 is fixedly mounted on the top of the socket 5, and the movable plug-in 6 is embedded in the inner cavity of the socket 5, so that the socket 5 slides against the outer wall of the movable plug-in 6. Stepped buffer assemblies are sequentially provided between the inner wall of the socket 5 and the movable plug-in 6.

[0037] During the falling process of the construction workers, they pass through multiple stepped buffer components in sequence, thereby reducing the force of gravity potential energy pulling the suspension rope, thereby improving the safety of the construction workers during the falling process.

[0038] The adjacent ends of the belt sling 2 and the hook sling 4 are connected by an anti-drop extension sling 8. One end of the anti-drop extension sling 8 is fixedly installed at the connection between the belt sling 2 and the movable plug-in 6, and the other end of the anti-drop extension sling 8 is fixed at the connection between the hook sling 4 and the socket 5.

[0039] During the falling process, one end of the anti-slip extension rope 8 will move with the falling movable plug-in 6. As the construction workers continue to fall, the anti-slip extension rope 8 will unfold. Since the length of the anti-slip extension rope 8 corresponds to the length of the movable plug-in 6, the movable plug-in 6 is prevented from being detached from the socket 5. The anti-slip extension rope 8 further improves the safety of the falling process.

[0040] The stepped buffer assembly includes wedge-shaped clips 10 provided on both side walls of the movable plug-in 6. On the outer walls of both sides of the movable plug-in 6, a plurality of wedge-shaped clips 10 are fixedly installed in sequence from top to bottom. The longitudinal section of the wedge-shaped clips 10 is a right triangle with an ascending hypotenuse.

[0041] . Wedge-shaped movable parts 17 opposite to the wedge-shaped clamping parts 10 are sequentially embedded on both sides of the inner wall of the socket 5. The longitudinal section of the wedge-shaped movable part 17 is a right triangle with a descending hypotenuse. The hypotenuse of the wedge-shaped movable part 17 is in a fitting position with the hypotenuse of the wedge-shaped clamping part 10. The movable plug-in 6 drives the wedge-shaped clamping parts 10 on both sides to slide over multiple wedge-shaped movable parts 17 in sequence. Multiple through grooves with shapes corresponding to the wedge-shaped movable parts 17 are opened in sequence from top to bottom on the inner wall of the socket 5, so that the wedge-shaped movable part 17 can be movably embedded in the through groove, and the wedge-shaped movable part 17 slides on the inner wall of the through groove.

[0042] The side of the wedge-shaped movable member 17 facing the outside of the socket 5 is fixed with a slider 7, and the slider 7 passes through the side wall of the socket 5 and extends to the outside. The slider 7 and the wedge-shaped movable member 17 are integrally formed, so that the slider 7 drives the wedge-shaped movable member 17 to slide in the through hole of the side wall of the socket 5. One end of the elastic member 18 is provided at the bottom of the slider 7, and the other end of the elastic member 18 is provided on the outer wall of the socket 5. The support plate 9 is fixed vertically at the bottom edge of the slider 7 outside the socket 5, so that the support plate 9 is in a position parallel to the socket 5. The elastic member 18 can be a compression spring, and the two ends of the elastic member 18 are respectively fixed to the opposite surfaces of the socket 5 and the support plate 9.

[0043] When a construction worker falls after wearing the safety belt 1, the safety belt 1 drives the movable plug-in 6 to slide down through the belt body rope 2, and the movable plug-in 6 drives the oblique edge of the wedge-shaped movable part 17 to slide over the oblique surface of the wedge-shaped clamping part 10 in sequence. The elastic force of the elastic part 18 reduces the tension between the belt body rope 2 and the hook body rope 4 during the fall, thereby playing a certain buffering effect and reducing the damage suffered during the fall.

[0044] The wedge-shaped movable member 17 and the wedge-shaped clamping member 10 are provided to prevent the movable plug-in unit 6 from entering the interior of the socket 5 when rebounding after falling, thereby improving safety during falling.

[0045] The wedge-shaped clamps 10 are sequentially fixed to the upper outer wall of the movable plug-in 6. By sequentially fixing the wedge-shaped clamps 10 on the outer walls on both sides of the movable plug-in 6 and being located on the outer wall of the upper part of the movable plug-in 6, the number of wedge-shaped clamps 10 is reduced, thereby bringing convenience to the production and processing process.

[0046] The sling connector includes a pillar 13 embedded in the intersection of the back of the safety belt 1. The end of the pillar 13 away from the safety belt 1 is threadedly connected with a disassembly cap 14. The anti-twist component is arranged between the disassembly cap 14 and the belt sling 2.

[0047] The support 13 is passed through the intersection of the back of the safety belt 1, and an external thread is provided on the outer wall of the support 13 away from the wearer, and an internal thread is provided on the inner wall of the removal cap 14. The installation and removal of the removal cap 14 and the support 13 make the installation and removal of the belt body rope 2 more convenient.

[0048] It is worth noting that the end of the pillar 13 extending into the safety belt 1 is provided with a waist pad 11. A support 12 is fixedly mounted on the end of the pillar 13 passing through the waist intersection of the safety belt 1, and a rubber waist pad 11 is fixedly mounted on the surface of the support 12, thereby providing protection for the wearer's waist.

[0049] In addition, the anti-twist assembly includes a steering support 15 fixedly mounted on the removable cap 14. A movable sleeve 16 is sheathed around the exterior of the steering support 15, and a rotating assembly is provided between the movable sleeve 16 and the belt sling 2. A spherical steering support 15 is fixedly mounted on the outward end of the removable cap 14. A spherical cavity is defined on the surface of the movable sleeve 16, which is larger than half a sphere. This allows the movable sleeve 16 to be flexibly sheathed around the exterior of the steering support 15, allowing the steering support 15 to move freely within the movable sleeve 16 without separating from the movable sleeve 16.

[0050] Through the movable cooperation between the steering support 15 and the movable sleeve 16, when the dismantling cap 14 and the support 13 are rotated and removed, the belt body hanging rope 2 will not be affected.

[0051] In addition, the rotating assembly includes a disc seat 22 fixed to the outer wall of the movable sleeve 16. A rotating connector 23 is provided on the outer portion of the disc seat 22. The rotating connector 23 is circular, and a circular cavity corresponding to the disc seat 22 is provided at the bottom of the rotating connector 23, so that the rotating connector 23 is sleeved on the outer portion of the disc seat 22, so that the rotating connector 23 rotates in contact with the outer wall of the disc seat 22.

[0052] An annular baffle 19 is embedded and installed on the outside of the rotating connecting seat 22. The annular baffle 19 is located at the bottom of the disc seat 22 and is sleeved on the outside of the connecting column between the disc seat 22 and the movable sleeve seat 16. The annular baffle 19 prevents the rotating connecting seat 23 from being separated from the disc seat 22.

[0053] The rotating connecting seat 23 is fixedly connected to the belt hanging rope 2.

[0054] When the belt rope 2 is kinked, the belt rope 2 drives the rotating connecting seat 23 to rotate, so that the rotating connecting seat 23 is fitted on the outer wall of the disc seat 22 and rotates circumferentially, thereby preventing the belt rope 2 from being kinked and improving the safety of the construction process.

[0055] Furthermore, balls 21 are evenly arranged circumferentially between the rotating connection seat 23 and the disc seat 22. A sliding groove 24 is opened circumferentially on the inner wall of the rotating connection seat 23, and a movable groove 20 is opened continuously on the outer wall of the disc seat 22. A ball 21 is movably embedded in each movable groove 20.

[0056] During the falling process, when the lifting rope is tangled, the rotating connecting seat 23 drives the inner wall slide groove 24 to slide against the outer wall of the multiple circumferential balls 21. At the same time, each ball 21 slides on the inner wall of each movable groove 20 respectively. The multiple circumferential balls 21 prevent the disc seat 22 and the rotating connecting seat 23 from falling off, thereby ensuring the safety of the operation process.

[0057] The anti-slip extension cord 8 is spirally stacked between the belt cord 2 and the hook cord 4. The anti-slip extension cord 8 is made of elastic material and is slightly longer than the movable insert 6. The elastic material of the anti-slip extension cord 8 reduces the impact of the falling process. The limited length of the anti-slip extension cord 8 prevents the movable insert 6 from rebounding and separating from the socket 5.
