Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an expansion bolt type safety rope buckle. Background Technology

[0002] In high-altitude operations such as construction, safety ropes are typically used to ensure worker safety. Currently, in the construction industry, workers' safety belts are mostly suspended from the scaffolding on the outside of the building. However, in high-rise buildings using climbing scaffolding or where external scaffolding has been dismantled early, the scaffolding is usually removed or raised during the construction of the secondary structure masonry and structural column formwork and pouring, leaving no safety belt suspension device on the outside of the building. This poses a significant safety hazard to construction workers. Therefore, an expansion bolt-type safety rope buckle has been developed. By installing this buckle inside the main reinforcement hole, a tack point is provided for the safety rope, providing excellent stability. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide an expansion bolt type safety rope buckle to solve the problems pointed out in the background art.

[0004] To achieve the aforementioned objectives of this utility model, the technical solution adopted is as follows:

[0005] An expansion bolt type safety rope buckle includes a fixed sleeve and a fixed rod. One end of the fixed rod extends into the fixed sleeve and is connected to the bottom of the fixed sleeve by an elastic element. The other end of the fixed rod extends out of the fixed sleeve and is fixed with a lifting ring for connecting a safety rope. The fixed rod is provided with multiple sets of elastic expansion clips. Each set of elastic expansion clips includes multiple elastic plates symmetrically arranged around the fixed rod, and two opposite elastic plates are arranged in a V-shape. The side wall of the fixed sleeve is provided with an opening for the elastic plates to pass through at the corresponding positions. A handle is fixed around the end of the fixed sleeve near the lifting ring.

[0006] As a further improvement of this utility model, the elastic plate includes an inclined portion and a horizontal portion. One end of the inclined portion near the elastic member is fixedly connected to the side wall of the fixed rod, and the other end is fixedly connected to one end of the horizontal portion.

[0007] As a further improvement of this utility model, a number of anti-slip protrusions are provided on the side of the horizontal part away from the fixed rod.

[0008] As a further improvement of this utility model, the anti-slip protrusion is a serrated protrusion.

[0009] As a further improvement of this utility model, the other end of the horizontal part has a first inclined surface, and the inclination direction of the first inclined surface is consistent with the inclination direction of the inclined part.

[0010] As a further improvement of this utility model, a second inclined surface is provided on both sides of the opening on the fixing sleeve, and the second inclined surface has the same inclination direction and inclination angle as the first inclined surface.

[0011] As a further improvement of this utility model, the elastic element is a spring.

[0012] As a further improvement of this utility model, one end of the fixing rod is provided with an annular locking platform, and the inner side wall of the fixing sleeve is provided with an annular limiting platform that cooperates with the annular locking platform. The setting of the annular limiting platform can further prevent the fixing rod from falling out of the fixing sleeve, and at the same time avoid damage to the elastic element during use.

[0013] As a further improvement of this utility model, the other end of the fixing sleeve is provided with a tapered part, which facilitates insertion into the reinforcing hole on the main structure.

[0014] As a further improvement of this utility model, a limiting plate is provided on the outer side of the fixing sleeve and near the handle. The limiting plate can ensure that the expansion bolt type safety rope buckle is pushed into place.

[0015] The beneficial effects of this utility model are: It has a simple structure, is easy to operate, and is reliably fixed, making the safety rope more stable during use. It is also easy to install and remove, reusable, and reduces construction costs. The design of the elastic expansion clip ensures the stability and reliability of the safety rope at the fixing point, ensuring that the safety rope will not fall off under stress. It also allows for quick fixing and release during use, improving the efficiency and safety of high-altitude operations. Attached Figure Description

Detailed Implementation

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1-3 As shown, an expansion bolt type safety rope buckle includes a fixed sleeve 1 and a fixed rod 2. One end of the fixed rod 2 extends into the fixed sleeve 1 and is connected to the bottom of the fixed sleeve 1 by an elastic element 3. The other end of the fixed rod 2 extends out of the fixed sleeve 1 and is fixed with a lifting ring 4 for connecting a safety rope. The fixed rod 2 is provided with multiple sets of elastic expansion clips 5. Each set of elastic expansion clips 5 includes multiple elastic plates 6 symmetrically arranged around the fixed rod 2, and two opposite elastic plates 6 are arranged in a V-shape. The side wall of the fixed sleeve 1 is provided with an opening 7 for the elastic plates 6 to pass through at the position corresponding to the position of the elastic plates 6. A handle 8 is fixed around the end of the fixed sleeve 1 near the lifting ring 4.

[0025] The elastic plate 6 includes an inclined portion 9 and a horizontal portion 10. One end of the inclined portion 9 near the elastic member 3 is fixedly connected to the side wall of the fixed rod 2, and the other end is fixedly connected to one end of the horizontal portion 10.

[0026] The horizontal part 10 has several anti-slip protrusions 11 on the side away from the fixed rod 2.

[0027] The anti-slip protrusion 11 is a serrated protrusion.

[0028] The other end of the horizontal part 10 has a first inclined surface 12, and the inclination direction of the first inclined surface 12 is consistent with the inclination direction of the inclined part 9.

[0029] The fixed sleeve 1 has a second inclined surface 13 on both sides of the opening 7, and the second inclined surface 13 has the same inclination direction and inclination angle as the first inclined surface 12.

[0030] The elastic element 3 is a spring.

[0031] One end of the fixing rod 2 is provided with an annular locking platform 14, and the inner side wall of the fixing sleeve 1 is provided with an annular limiting platform 15 that cooperates with the annular locking platform 14. The setting of the annular limiting platform 15 can further prevent the fixing rod 2 from falling out of the fixing sleeve 1, and at the same time avoid damage to the elastic element 3 during use.

[0032] The other end of the fixing sleeve 1 is provided with a tapered part 16, which facilitates insertion into the reinforcement hole on the main structure.

[0033] A limiting plate 17 is provided on the outer side of the fixing sleeve 1 and near the handle 8.

[0034] like Figure 4 As shown, in use, the present invention is pushed into the reinforcement hole of the main structure. By pushing the lifting ring 4, the elastic expansion clip 5 is contracted. After being pushed in place, the lifting ring 4 is pulled, causing the elastic expansion clip 5 to spring open in the reinforcement hole, forming an eight-corner structure. When the safety rope fixed on the lifting ring 4 is under force, the elastic clip 6 passes through the opening 7 and is tightly clamped on the inner wall of the reinforcement hole. The horizontal part 10 of the elastic clip 6 is provided with several anti-slip protrusions 11 on the side away from the fixing rod 2. The anti-slip protrusions 11 can further increase the friction between the elastic clip 6 and the inner wall of the reinforcement hole, making the safety rope more stable during use. When the present invention is not in use, the fixing rod 2 is pushed into the reinforcement hole, which will cause the elastic expansion clip 5 to contract, thereby allowing the expansion bolt type safety rope buckle to be pulled out of the reinforcement hole.

[0035] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, component disassembly or combination, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
