Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an anti-loosening fixing structure for furniture connectors. Background Technology

[0002] Furniture is an object used to support and store items or to provide comfort and functionality in environments such as homes and offices. Furniture can include various types of home furnishings and decorations such as beds, sofas, tables, chairs, cabinets, and bookshelves. In the process of furniture making and assembly, angle iron is often used to provide additional support and reinforcement for connectors, and is commonly used for connecting and fixing structural components such as tables, chairs, cabinets, and bookshelves.

[0003] Chinese patent discloses an angle iron (authorization announcement number CN203240258U). This patented technology includes a body composed of two horizontally connected and vertically arranged cross plates. Each of the two cross plates has an anti-saw layer on its outer edge, with the thickness of the anti-saw layer being the same as the thickness of the cross plate. A triangular prism-shaped support strip is provided at the connection point of the two cross plates. Each of the two cross plates has several parallel, straight anti-saw strips, the same length as the support strip and parallel to each other. Reinforcing ribs are provided between the cross plates and the vertical plate. This angle iron has the advantage of strong anti-saw and anti-destructive capabilities.

[0004] This patented technology has the advantage of high strength when used, but there are still shortcomings in its application. Angle iron is fixed to furniture with bolts, but bolts and other fasteners can loosen during use, causing the connected furniture structural parts to wobble and become unstable, affecting the use of the furniture. Therefore, those skilled in the art have provided an anti-loosening fixing structure for furniture connectors to solve the problems mentioned in the background art. Utility Model Content

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0040] Example 1

[0041] Please see Figures 1-5 As shown, this embodiment is an anti-loosening fixing structure for furniture connectors, including angle iron 100 and furniture structural component 101.

[0042] The fixing structure 200 includes mounting holes 209 opened inside the angle iron 100 and the furniture structural component 101, bolts 210 located inside the mounting holes 209, nuts 211 sleeved on the outer wall of the bolts 210, collars 207 located on the outer wall of the nuts 211, slots 208 arranged in a ring array on the outer wall of the collars 207, a bracket 202 fixed at one end of the angle iron 100, a pressure rod 203 slidably inserted into the bracket 202, a limiting ring 205 sleeved on the outer wall of the pressure rod 203, a spring 204 fixed at one end of the limiting ring 205 and connected to the bracket 202, a locking block 206 fixed at one end of the pressure rod 203 and locked inside the slots 208, and a pull ring 201 fixed at the upper end of the pressure rod 203.

[0043] Use of fixed structure 200;

[0044] Angle iron 100 is placed at the corner of the furniture structural component 101. Bolt 210 passes through mounting hole 209. One end of nut 211 is threaded onto the outer wall of bolt 210. As nut 211 rotates, it drives collar 207 to move synchronously, gripping pull ring 201 and pulling lever 306 longitudinally. Lever 306 drives limit ring 205 to move longitudinally, compressing spring 204. Spring 204 contracts under pressure. After nut 211 rotates to tighten bolt 210, it relaxes. Ring 201 and spring 204 push the limiting ring 205 longitudinally through their own elasticity, causing the locking block 206 to be inserted into the slot 208 on the outer wall of the collar 207, applying a locking force to the nut 211 to prevent the nut 211 from loosening during use. The bolt 210 gradually loosens during use, and its own loosening force is insufficient to lift the locking block 206 supported by spring 204. The angle iron 100 is stable during use, ensuring the stability of the furniture structural component 101 during use.

[0045] Example 2

[0046] Please see Figures 1-5 As shown, this embodiment further includes elements beyond those in embodiment 1;

[0047] as well as;

[0048] The reinforcing structure 300 includes a side plate 303, a side groove 312 formed inside the side plate 303, and a connecting block 304 slidably inserted into the side groove 312.

[0049] The angle iron 100 has symmetrically distributed mounting blocks 301 at one end, and the side plate 303 has rotating shafts 302 that are rotatably installed inside the mounting blocks 301 at both the front and rear ends.

[0050] The furniture structural component 101 has a positioning groove 305 inside, and one end of the docking block 304 is slidably inserted into the positioning groove 305.

[0051] The docking block 304 has a positioning hole 311 inside, and the furniture structural component 101 has a stroke hole 310 that passes through the positioning groove 305 inside;

[0052] A locking rod 306 is slidably inserted into the stroke hole 310, and a connecting block 307 is provided at one end of the locking rod 306;

[0053] A pull handle 308 is provided at the lower end of the connecting block 307, and a spring 309 is sleeved on the outside of the locking rod 306 and fixed between the connecting block 307 and the furniture structural component 101;

[0054] Use of reinforcement structure 300;

[0055] During the installation of angle iron 100, side plate 303 rotates inside mounting block 301 via pivot 302 and is inserted into side groove 312 and positioning groove 305 via mating block 304. At this time, gripping handle 308 applies pulling force to spring 309, causing locking rod 306 to move laterally. After mating inside positioning hole 311 and travel hole 310, locking rod 306 is reset by the elastic force of spring 309 and inserted into positioning hole 311 and travel hole 310, locking mating block 304. The mating block 304 is thus fixed. At this time, angle iron 100 is supported by mating block 304 and side plate 303, improving the strength of angle iron 100. During the use of angle iron 100, the reinforcement strength of furniture structural component 101 is improved.
