In the height of guide post 12.
The state diagram in assembling process is given such as Fig. 8 and Fig. 9.During pressing buckle, 11 stress deformation of elastic portion
Across card hole 21, and before first connecting portion 1 and second connecting portion 2 are not completely assembled to position, leading in first connecting portion 1
The locating slot 221 on elastic piece 22 can be withstood to column 12 and drives elastic piece 22 that flexible deformation occurs and pushes, when elastic portion 11
Engaging groove 111 and 2 bottom side of second connecting portion snap fit tabs 23 cooperation in place after, elastic piece 22 restore elasticity.For two
Cooperate between a part more fasten it is firm, can with design flexibility portion 11 engaging groove 111 and 2 bottom side of second connecting portion engaging
Guide post 12 and locating slot 221 still have certain up and down direction amount of interference after 23 cooperation in place of protrusion, as shown in figure 4, this amount of interference
It may be designed as 0.05mm~0.2mm for h, h.In this way after the assembly is completed, first connecting portion 1 and second connecting portion 2 can be in elasticity
Cooperate under the action of 22 elastic deformation force of piece and more fasten, greatly reduces the gap between two mating parts, largely
Reduce noise caused by fit clearance and shaking.
Optionally embodiment, telescoping mechanism are spring.
Spring can also be used in telescoping mechanism, and structure is simple.
Optionally embodiment, telescoping mechanism include telescopic rod and driving device, and the output shaft of driving device passes through
Transmission device is connected with telescopic rod.
It can be achieved using motor-driven telescopic rod or the telescopic rod of hydraulic-driven.
Optionally embodiment, self-locking mechanism are set in first connecting portion 1 and/or second connecting portion 2.
The setting position of self-locking mechanism can flexibly be determined according to specific structure.
Optionally embodiment, the first buckle snap through the relative motion on first direction and realize card with second
It closes and is detached from.
First buckle only can be achieved with engaging or be detached from the second buckle by the upward movement of upper and lower, convenient for automatic
Metaplasia produces, and assembly efficiency is high.
To dismantle this buckle connecting structure, then needs first to press first connecting portion 1 and second connecting portion 2, make guide post
12 withstand lower snaps into position slot 221 and make elastic piece 22 that certain elastic deformation occur, to the engaging groove in upper first connecting portion 1
111 and second connecting portion 2 on snap fit tabs 23 be staggered completely, then turn left respectively, turn right and break two elastic portions 11 into two with one's hands and keep its complete
At this moment total detachment second connecting portion 2 is lifted up i.e. removable two parts of first connecting portion 1 again.
A kind of shell provided by the utility model, including any of the above buckle connecting structure.
A kind of electrical equipment provided by the utility model, including above-mentioned shell.
Optionally embodiment, electrical equipment are air conditioner.
A concave-convex fit structure is devised at the cooperation of elastic portion 11 and card hole 21, while devising an elastic piece 22
