Description

Technical Field

[0001] This utility model relates to the field of scaffolding fasteners, and in particular to a fastening assembly and a fastening scaffolding. Background Technology

[0002] In construction, scaffolding is an indispensable temporary structure used to support personnel and materials and ensure construction safety. Coupled scaffolding is a common type of scaffolding structure. Right-angle couplers are key components for connecting the members of the coupled scaffolding, and their stability directly affects the safety of the entire scaffolding. Existing right-angle couplers are usually used to connect and fix scaffolding members through fixing bolts and fixing nuts.

[0003] However, in actual use of scaffolding, due to vibrations at the construction site, wind, or material fatigue caused by prolonged use, the fixing nuts are prone to loosening, affecting the structural stability of the scaffolding and increasing safety risks during construction. Therefore, in order to solve the problem of loose fixing nuts, this utility model proposes a fastening component and a fastening scaffolding. Utility Model Content

[0004] The purpose of this utility model is to provide a fastening assembly and a fastening scaffold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fastening assembly, including a right-angle fastener, and further comprising:

[0006] A fixing structure is used to connect and fix right-angle couplers to scaffolding. The fixing structure includes a fixing buckle hinged to the top and bottom of the right-angle coupler. A fixing bolt for connecting the fixing buckle is inserted through the side of the right-angle coupler. A fixing nut is fitted on the outer thread of the fixing bolt.

[0007] An anti-loosening structure is provided at the intersection of the fixing nut and the right-angle fastener. The anti-loosening structure includes a sleeve fitted on the outside of the fixing bolt, a pressure ring fitted on the outside of the sleeve, and a spring-loaded part provided on the side of the pressure ring near the fixing buckle.

[0008] Preferably, the spring-loaded part includes a compression spring, which is sleeved on the outside of the fixing bolt, and the fixing bolt is used to compress the fixing bolt.

[0009] Preferably, a rubber ring is provided on the outer side of the fixing bolt, and the rubber ring is located on the opposite side of the pressure ring and the nut end of the fixing bolt. The rubber ring is used to prevent friction between the fixing bolt and the pressure ring.

[0010] Preferably, the fixing buckle has a fixing slot on its side, which is used for inserting fixing bolts.

[0011] Preferably, the clamping side of the fixing buckle is provided with a friction pad, which is used to increase the friction between the fixing buckle and the scaffold.

[0012] A snap-fit ​​scaffolding system employs the snap-fit ​​assembly described above, comprising multiple sets of uprights arranged symmetrically, multiple sets of horizontal bars arranged symmetrically on opposite sides of the multiple sets of uprights, and multiple sets of connecting rods arranged on opposite sides of the uprights. The snap-fit ​​assembly is disposed at the connection points of the uprights, horizontal bars, and connecting rods.

[0013] Preferably, a pad is provided at the bottom of the upright, the pad being used to increase the contact area between the upright and the ground.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This utility model provides an anti-loosening structure on the outside of the fixing bolt at the connection between the right-angle coupler and the fixing buckle used to fix the scaffold pole. After the fixing bolt and the fixing nut are tightened, the pressure ring in the sleeve squeezes and compresses the spring. The compression spring applies a thrust to the fixing bolt in the opposite direction, so that the thread engagement of the fixing bolt and the fixing nut is tightly contacted, thereby preventing the fixing nut from loosening due to vibration during the use of the scaffold.

[0022] 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.

[0023] This utility model provides, for example Figure 1-5 The fastening assembly shown includes a right-angle fastener 4, and further includes a fixing structure and an anti-loosening structure 5;

[0024] Specifically, the fixing structure is used to connect and fix the right-angle coupler 4 to the scaffold. The fixing structure includes a fixing buckle 401 hinged to the top and bottom of the right-angle coupler 4. A fixing bolt 402 for connecting the fixing buckle 401 is inserted through the side of the right-angle coupler 4. A fixing nut 403 is threaded on the outer side of the fixing bolt 402.

[0025] It should be noted that a friction pad 4012 is adhesively provided on the clamping side of the fixing buckle 401. The friction pad 4012 is made of rubber and is used to increase the friction between the fixing buckle 401 and the scaffold pole. The end of the fixing bolt 402 is sequentially inserted and connected to the right angle fastener 4 and the fixing buckle 401. The fixing buckle 401 has a fixing slot 4011 on its side, which is used for the fixing bolt 402 to pass through.

[0026] Specifically, the anti-loosening structure 5 is provided at the intersection of the fixing nut 403 and the right-angle fastener 4. The anti-loosening structure 5 includes a sleeve 501 sleeved on the outside of the fixing bolt 402, and a pressure ring 502 is sleeved on the outside of the sleeve 501.

[0027] It should be noted that the right-angle fastener 4 has a through slot for the insertion of the fixing bolt 402, and the pressure ring 502 is square and can move in the inner cavity of the sleeve 501. The sleeve 501 is set in the through slot, and the pressure ring 502 has a spring-loaded part on the side near the fixing buckle 401.

[0028] Specifically, the spring-rebound part includes a compression spring 503, which is sleeved on the outside of the fixing bolt 402, and the fixing bolt 402 is used to compress the fixing bolt 402.

[0029] It should be noted that the nut of the fixing bolt 402 can be inserted into the inner cavity of the sleeve 501, thereby pushing the pressure ring 502 to squeeze and compress the spring 503. A rubber ring 504 is bonded to the outside of the fixing bolt 402. The rubber ring 504 is located on the opposite side of the pressure ring 502 and the nut end of the fixing bolt 402. The rubber ring 504 is used to prevent friction between the fixing bolt 402 and the pressure ring 502.

[0030] A snap-fit ​​scaffolding uses the snap-fit ​​assembly described above, including multiple sets of uprights 1 arranged symmetrically, multiple sets of horizontal bars 2 arranged symmetrically on opposite sides of the multiple sets of uprights 1, and multiple sets of connecting rods 3 arranged on opposite sides of the uprights 1. The snap-fit ​​assembly is located at the connection between the uprights 1, the horizontal bars 2 and the connecting rods 3.

[0031] It should be noted that the two fixing buckles 401 hinged by the right angle fastener 4 fix the connection between the upright 1, the horizontal bar 2 and the connecting rod 3. A pad 101 is provided at the bottom of the upright 1 to increase the contact area between the upright 1 and the ground.

[0032] In actual use, an anti-loosening structure 5 is provided on the outside of the fixing bolt 402 at the connection between the right-angle coupler 4 and the fixing buckle 401 used to fix the scaffold pole. After the fixing bolt 402 and the fixing nut 403 are tightened, the pressure ring 502 in the sleeve 501 squeezes the compression spring 503. The compression spring 503 applies a thrust to the fixing bolt 402 in the opposite direction, so that the thread engagement of the fixing bolt 402 and the fixing nut 403 is in close contact, thereby avoiding the situation where the fixing nut 403 loosens due to vibration during the use of the scaffold.
