Abstract

The utility model discloses an aluminum material connecting structure which is convenient for assembling/disassembling and can realize repeated assembling/disassembling of aluminum materials. The aluminum material connecting structure comprises two aluminum materials which are mutually matched. Embedding grooves which are mutually nested are respectively formed at the matching ends of the two aluminum materials along the length direction, wall bodies of the two embedding grooves are surrounded into groove holes after the nesting, and elastic pin columns are inserted in the groove holes. After the above technical scheme is adopted, the rubber pin columns are plugged into the groove holes which are formed after the two aluminum materials are nested, and the two aluminum materials are stably connected together by utilizing the contractility and elasticity of rubber; the disassembling can be realized only by pulling out the rubber pin columns; therefore, both the assembling and disassembling are fairly convenient and can be repeated for unlimited times.

Description

A kind of linkage structure of aluminium

Technical field:

The utility model relates to a kind of linkage structure of aluminium.

Background technique:

Need use the industry of aluminium at present at furniture, building etc., the connection of two aluminiums is generally being adopted the directly fastening or employing angle sign indicating number connection of welding, screw, employing is welded to connect, in case after the aluminium welding, it is destructive sawed-off to need dismounting to adopt, if assembly can only weld again again, assembly and dismounting need utilize welding machine and saw, and dismounting is inconvenience very; And directly fastening the connection with employing angle sign indicating number of screw all is that the mode that adopts tapping screw to creep into aluminium realizes installing, after the dismounting several times, because aluminium properties of materials, screw wearing and tearing on the aluminium, screw can not screw in original screw, must be in other place perforate again for screw precession, repeated non-constant.

Summary of the invention:

The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, a kind of assembly and disassembly of being convenient to be provided, can realizing that aluminium repeats the aluminium linkage structure of repeatedly dismounting.

For achieving the above object, the technological scheme that the utility model provides is: a kind of linkage structure of aluminium, include two aluminiums of working in coordination, abutting end at two aluminiums forms caulking groove nested against one another along its length respectively, and nested back is surrounded by slotted eye by two caulking groove wall bodies, injects flexible pin in the hole.

Wall body corner at caulking groove forms stiffening rib.

Described elasticity pin is the rubber pin.

After adopting technique scheme, the rubber pin plunger is advanced in the slotted eye of two aluminiums nested back formation, utilize the contractibility and the elasticity of rubber, two aluminiums linking together steadily, just can realize dismounting as long as extract the rubber pin during dismounting, dismounting is all quite convenient, and can unlimitedly repeat.

Embodiment:

Now elaborate the utility model in conjunction with the accompanying drawings:

Present embodiment is an aluminium bookcase, linkage structure between the bookcase aluminium includes two aluminiums of working in coordination 11,12, at the abutting end of two aluminiums 11,12 side's of forming hook- type caulking groove 21,22 respectively along its length, form stiffening rib 31,32 in second corner of this side's hook- type caulking groove 21,22, two side's hook- type caulking grooves 21,22 are nested against one another, and nested back is surrounded by square slotted eye 4 by the wall body of two caulking grooves 21,22, and the two ends of square slotted eye 4 are all injected separately square rubber pin 51,52.As shown in Figure 4, as long as nested, fill in the assembling of just finishing bookcase behind the rubber pin 51,52 two caulking grooves 21,22 on each tie point of bookcase, during dismounting, pull out rubber pin 51,52, two aluminiums 11,12 nested against one another are pulled away from just passable, it is quite convenient to operate.After laying out books on the bookcase, the effect that the aluminium of bookcase can be under pressure, and two caulking grooves of aluminium joint are the places of most fragile in whole bookcase structure, the existence of stiffening rib 31,32 can the side's of increase hook- type caulking groove 21,22 intensity, when preventing that two caulking grooves are stressed, the wall body of side's hook- type caulking groove 21,22 deforms, the steadiness that influence connects.Because it is destructive that disassembly process can not produce accessory, so can realize unlimited repetition dismounting.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.

Claims (3)

1. the linkage structure of an aluminium, include two aluminiums of working in coordination (11,12), it is characterized in that: the abutting end at two aluminiums (11,12) forms caulking groove nested against one another (21,22) along its length respectively, and nested back is surrounded by slotted eye (4) by two caulking grooves (21,22) wall body, injects flexible pin (51,52) in the hole.
