Description

Technical Field

[0001] This utility model relates to the field of fastener technology in building engineering, specifically a high-strength anti-slip connecting fastener. Background Technology

[0002] Fasteners generally refer to intermediate connecting parts that connect two components. In construction engineering, they are mostly used to fix steel pipe scaffolding with an outer diameter of Φ48mm. However, existing devices have certain drawbacks. For example, the high-strength right-angle fastener described in announcement number CN222140669U involves the field of fasteners and includes a fixing seat. The fastener is hinged to the left front end of the fixing seat, and the screw at the right front end of the fixing seat passes through the concave plate on the right side of the fastener. An anti-slip mechanism is set on the inner front end face of the fixing seat.

[0003] Although the above-mentioned device increases friction for anti-slip operation and reinforces the fasteners, in actual use, the fasteners can be reused, while the anti-slip pads and the studs used for installation are consumables and are susceptible to aging and stripping. The above-mentioned fasteners are not convenient to disassemble quickly, which increases the cost of using the fasteners. Utility Model Content

[0004] The purpose of this invention is to provide a high-strength, anti-slip connecting fastener to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-strength anti-slip fastener includes two No. 1 half-hoops and two No. 2 half-hoops. The upper surface of the No. 1 half-hoops is embedded with a pin, and the outer surface of the pin is rotatably connected to the No. 2 half-hoops.

[0007] The first connecting module is movably connected to the internal part of the first half hoop. The first connecting module includes a first connecting half hoop and a first connecting frame. The first connecting half hoop is movably connected to one end of the first half hoop, and the first connecting frame is fixedly connected to the other end of the first connecting half hoop.

[0008] The second half hoop has a second connecting module embedded in its interior. The second connecting module includes a second connecting half hoop and a second connecting frame. The second connecting half hoop is embedded in and movably connected to one end of the second half hoop, and the second connecting frame is fixedly connected to the other end of the second connecting half hoop.

[0009] The outer surfaces of both the first and second connecting frames are nested with non-slip rubber sleeves.

[0010] Furthermore, the first half-hoop has an insertion groove on its side surface, a reinforcing half-ring is fixedly connected to its outer surface, a reinforcing plate is fixedly connected to its outer surface, and a limiting groove is formed on its outer surface.

[0011] Furthermore, the first connecting frame corresponds to the first insertion slot, the other end of the first connecting frame is fixedly connected to a first insertion block, the first insertion block is inserted into the side wall of the first insertion slot, the upper surface of the first connecting half hoop is fixedly connected to a first limiting protrusion, the first limiting protrusion matches the first limiting slot, and the upper surface of the first limiting protrusion is threadedly connected to a first screw.

[0012] Furthermore, the second half hoop has a second insertion groove on its side surface, a second reinforcing half ring is fixedly connected to the outer surface of the second half hoop, a second reinforcing plate is fixedly connected to the outer surface of the second reinforcing half ring, and a second limiting groove is provided on the outer surface of the second half hoop.

[0013] Furthermore, the second connecting frame corresponds to the second insertion slot, the other end of the second connecting frame is fixedly connected to a second insertion block, the second insertion block is inserted into the side wall of the second insertion slot, the upper surface of the second connecting half hoop is fixedly connected to a second limiting protrusion, the second limiting protrusion matches the second limiting slot, and the upper surface of the second limiting protrusion is threadedly connected to a second screw.

[0014] Furthermore, the first connecting module also includes a stud, a washer, and a nut. The stud is hinged to one end of the first connecting half-hoop, the washer is nested and connected to the outer surface of the stud, and the nut is threaded and connected to the outer surface of the stud.

[0015] Furthermore, a connecting block is fixedly connected to the outer surface of the first half hoop, and adjacent first half hoops are fixedly connected by the connecting block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Manually pull the first connecting frame outward to separate the first insertion block from the pre-drilled hole on the side wall of the first insertion slot. This further separates the first connecting frame, along with the anti-slip rubber sleeve and the first half-hoop. This allows the anti-slip rubber sleeve and the first connecting half-hoop to be quickly separated from the first half-hoop. At the same time, the anti-slip rubber sleeve can be replaced after it ages, and a new first connecting half-hoop can be replaced after the stud or nut strips. This extends the service life of the device. The second half-hoop and the anti-slip rubber sleeve are handled similarly. This makes the fastener as a whole a modular structure, which facilitates the quick replacement of damaged parts when the fastener is reused, and helps to save on the cost of using the fastener.

[0018] 2. The No. 1 and No. 2 reinforced semi-rings, together with the No. 1 and No. 2 reinforced plates, increase the strength of the No. 1 and No. 2 semi-hoops. The anti-slip rubber sleeve is used to increase the friction between the pipe fitting and the fastener to prevent the fastener from slipping off. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 In this embodiment of the utility model, a high-strength anti-slip connecting fastener includes two No. 1 half-hoops 1 and two No. 2 half-hoops 2. The upper surface of the No. 1 half-hoops 1 is embedded with a pin 3, and the outer surface of the pin 3 is rotatably connected to the No. 2 half-hoops 2.

[0026] The first connecting module 5 is embedded and movably connected inside the first half hoop 1. The first connecting module 5 includes a first connecting half hoop 501 and a first connecting frame 503. The first connecting half hoop 501 is embedded and movably connected to one end of the first half hoop 1, and the first connecting frame 503 is fixedly connected to the other end of the first connecting half hoop 501.

[0027] The second connecting module 6 is internally embedded and slidably connected to the second half hoop 2. The second connecting module 6 includes a second connecting half hoop 601 and a second connecting frame 603. The second connecting half hoop 601 is embedded and movably connected to one end of the second half hoop 2, and the second connecting frame 603 is fixedly connected to the other end of the second connecting half hoop 601.

[0028] The outer surfaces of both the first connecting frame 503 and the second connecting frame 603 are nested with non-slip rubber sleeves 4.

[0029] Specifically, when this fastener is used, the pipe fitting is fixed by the cooperation of the first half-clamp 1 and the second half-clamp 2 with the pin 3, and the first half-clamp 1 and the second half-clamp 2 have two sets that can fix two pipes.

[0030] The first connecting half hoop 501 is connected together with the first connecting frame 503 and the first half hoop 1;

[0031] The second connecting half hoop 601 is connected together with the second connecting frame 603 and the second half hoop 2;

[0032] The anti-slip rubber sleeve 4 is used to increase the friction between the pipe fitting and the fastener. The first connecting half-clamp 501 and the second connecting half-clamp 601 fix the anti-slip rubber sleeve 4. At the same time, the first connecting half-clamp 501 and the second connecting half-clamp 601 can be disassembled separately, so that the fastener is a modular structure. This makes it easy to quickly replace the damaged parts when the fastener is reused, which helps to save the cost of using the fastener.

[0033] Example 1

[0034] like Figure 1-4 As shown, a first insertion groove 101 is formed on the side surface of the first half-hoop 1, a first reinforcing half-ring 102 is fixedly connected to the outer surface of the first half-hoop 1, a first reinforcing plate 104 is fixedly connected to the outer surface of the first reinforcing half-ring 102, a first limiting groove 105 is formed on the outer surface of the first half-hoop 1, a first connecting frame 503 corresponds to the first insertion groove 101, a first insertion block 504 is fixedly connected to the other end of the first connecting frame 503, the first insertion block 504 is inserted into the side wall of the first insertion groove 101, a first limiting protrusion 502 is fixedly connected to the upper surface of the first connecting half-hoop 501, the first limiting protrusion 502 matches the first limiting groove 105, and a first screw is threadedly connected to the upper surface of the first limiting protrusion 502.

[0035] In this embodiment, when disassembling the first half-hoop 1 and the first connecting half-hoop 501, a tool is used to remove the first screw. At this time, the first connecting frame 503 is manually pulled outward, which can separate the first insertion block 504 from the hole reserved on the side wall of the first insertion slot 101, and further separate the first connecting frame 503 together with the anti-slip rubber sleeve 4 and the first half-hoop 1. This allows the anti-slip rubber sleeve 4 and the first connecting half-hoop 501 to be quickly separated from the first half-hoop 1. At the same time, the anti-slip rubber sleeve 4 can be replaced after it ages, and a new first connecting half-hoop 501 can be replaced after the stud 505 or nut 507 strips, thereby extending the service life of the device.

[0036] like Figure 1-4 As shown, the second half-hoop 2 has a second insertion groove 201 on its side surface. A second reinforcing half-ring 202 is fixedly connected to the outer surface of the second half-hoop 2. A second reinforcing plate 204 is fixedly connected to the outer surface of the second reinforcing half-ring 202. A second limiting groove 205 is opened on the outer surface of the second half-hoop 2. The second connecting frame 603 corresponds to the second insertion groove 201. A second insertion block 604 is fixedly connected to the other end of the second connecting frame 603. The second insertion block 604 is inserted into the side wall of the second insertion groove 201. A second limiting protrusion 602 is fixedly connected to the upper surface of the second connecting half-hoop 601. The second limiting protrusion 602 matches the second limiting groove 205. A second screw is threadedly connected to the upper surface of the second limiting protrusion 602.

[0037] In this embodiment, the disassembly of the second half hoop 2 and the second connecting half hoop 601 is similar, which facilitates the replacement of the anti-slip rubber sleeve 4 on the second half hoop 2. In addition, the first reinforcing half ring 102 and the second reinforcing half ring 202, together with the first reinforcing plate 104 and the second reinforcing plate 204, increase the strength of the first half hoop 1 and the second half hoop 2.

[0038] Example 2

Under the push of the thread, the nut 507 drives the washer 506 to move, so that the washer 506 and the second connecting half-clamp 601 come into contact, thus completing the connection between the first half-clamp 1, the second half-clamp 2 and the pipe fitting.

[0042] like Figure 1-4 As shown, a connecting block 103 is fixedly connected to the outer surface of the first half hoop 1, and adjacent first half hoops 1 are fixedly connected by the connecting block 103.

[0043] In this embodiment, the two connecting blocks 103 are connected together by welding, and the two pipes can be fixed by two sets of No. 1 half hoop 1 and No. 2 half hoop 2.
