Expansion fixing connection structure for home hardware

Abstract

The invention relates to an expansion fixing connection structure for home hardware. The structure is characterized by comprising a handle body and an expansion fixing assembly, the expansion fixing assembly comprises a fixing base, a fastening block and an adjusting screw, the fixing base and the handle body are of an integrated structure or the fixing base is fixed to the handle body, the side wall of the fixing base is provided with a guide slope, the end face of one end of the fastening block is provided with antiskid raised grains, the other end of the fastening block is tightly attachedto the guide slope, the adjusting screw rotationally penetrates in the fixing base or the handle body or penetrates in the handle body and the fixing base at the same time and is in screwed connectionwith the fastening block, and therefore when the adjusting screw is screwed, the fastening block slides in the inclination direction of the guide slope. The expansion fixing connection structure hasthe advantages of being simple in structure, high in assembling efficiency, firm in fixing, good in reliability, long in service life and the like, can be repeatedly disassembled and assembled, and will not damage an installation portion even if being repeatedly disassembled and assembled, completeness of the installation portion is effectively ensured, and the installation portion can be repeatedly used.

Description

technical field [0001] The invention relates to the field of household products, in particular to an expansion-fixed connection structure of household hardware. Background technique [0002] At present, most of the household products are directly fixed on the corresponding components by screws during the connection process. Among them, the screw is fixed, the contact area is small, and the force acts directly on the joint of the screw, so that the screw hole is prone to deformation under long-term stress, which makes the household products loose and fall off. Especially on the components connected by screws, under the long-term gravity and the use of household products, the threads of the threads are prone to loosening and falling off. On the component, once the screw loosens and falls off, it is difficult to firmly fix it at the same hole position, and the same hole position cannot be used repeatedly. Moreover, disassembling the screws on the component will also damage th...

Problems solved by technology

Among them, the screw is fixed, the contact area is small, and the force acts directly on the joint of the screw, so that the screw hole is prone to deformation under long-term stress, which makes the household products loose and fall off.

Especially on the components connected by screws, under the long-term gravity and the use of household products, the threads of the threads are prone to loosening and falling off

On the component, once the screws loosen and fall off, it is difficult to fix them firmly in the same hole position, and the same hole position cannot be used repeatedly

And disassembling the screws on the component will also damage the thread, which will make the reliability of the connection structure impossible to achieve repeated disassembly and assembly

Therefore, the reliability of the existing screw connection method is low, which may easily lead to a reduction in the service life of household products.

Because this connection method requires threaded holes on the components, and the threaded holes are more complicated to open, and in order to ensure the reliability of the connection structure, a large number of screws are generally used for fixing, which will easily lead to a decrease in the assembly efficiency of household products
