Embodiment
Embodiment one:
As Fig. 1 to 7 show the preferred embodiment of the sleeve-assembled structure of the present invention sleeve structure include first sleeve 21,
Second sleeve pipe 22, the first sliding block 23 and the second sliding block, the sleeve pipe 22 of first sleeve 21 and second are straight tube structure and are pipe
Structure, the first sliding block 23 is circular ring, and the second sliding block is four strip sliding blocks 24, and the sleeve structure is particularly suitable for use in the
One end of two sleeve pipes is provided with miscellaneous part and the first sliding block 23 is situation about being located between the part and the second sliding block.
Second sleeve pipe 22 is sheathed in first sleeve 21, and the inwall of first sleeve 21 and the second sleeve pipe 22 outer wall it
Between have spacing, the first sliding block 23 is also sheathed on the second sleeve pipe 22, and the first sliding block 23 is fixed on one end of first sleeve 21, first
Sleeve pipe 21 on the inwall at the end be provided with groove 211, the first sliding block 23 towards the side of first sleeve 21 provided with four along
The axial direction of first sleeve 21 is to the connecting portion 231 extended inside first sleeve 21, and four connecting portions 231 are in the first sliding block
23, each connecting portion 231, which prolongs, to be extended at the position of 21 interior grooves of first sleeve 211, and connecting portion 231 is in the position
Place is sticked into groove 211 by screens portion 232 and realized and first provided with the screens portion 232 sticked into groove 211, the first sliding block 23
Sleeve pipe 21 is fixedly connected.
Four strip sliding blocks 24 are fixed on the lateral wall of the one end of the second sleeve pipe 22, and four strip sliding blocks 24 are symmetrical
Around being distributed in around the second sleeve pipe 22, it is equipped with the second sleeve pipe 22 at each position of strip sliding block 24 of correspondence
Jack 222, strip sliding block 24 is provided with the inserting column 241 stretched into jack 222, and strip sliding block 24 passes through inserting column 241
Realize and be fixedly mounted on the second sleeve pipe 22 in insertion jack 222.It is four long when first sleeve 21 is enclosed on the second sleeve pipe 22
Bar shaped sliding block 24 is located between the sleeve pipe 22 of first sleeve 21 and second, and is equipped with each outer surface of strip sliding block 24 convex
The draw runner 242 risen, is provided with axially extending and through first set along first sleeve 21 correspondence is each on the inwall of first sleeve 21
The chute 212 at the two ends of pipe 21, strip sliding block 24 coordinates realization to be slided with first sleeve 21 and matched somebody with somebody by draw runner 242 and chute 212

It is upper further fixed.
The back box 11 and bottom 12 of the base of the present embodiment use floating connection, specifically, setting card in the side wall of bottom 12
Tenon 122, the side wall correspondence position of back box 11 sets positioning hole 111, and trip 122 fastens to positioning bottom cap 12 in positioning hole 111, and card
The top of tenon 122 is provided with inclined-plane 124, due to the presence on inclined-plane 124, it is allowed to which back box 11 has certain flying height, when motor works
The vibration of generation, can be offset, it is to avoid motor oscillating is directly delivered in back box 11 by fluctuating for back box 11.Back box 11
Side wall be provided with in-flanges screwed hole 110, the screwed hole 110 be generally used for connect supporting desktop framework, in prior art
In, the inner space of back box 11 is smaller, and has the stop of electric machine spacing structure, to avoid interference with, and the in-flanges of screwed hole can not
Length is enough done, the connection of framework and back box is unreliable.The inner space of the present embodiment back box 11 is larger, and stops without structural member,
The in-flanges of screwed hole 110 can be lengthened, it is not necessary to worry the interference with the structural member in back box, so, just increasing screw thread has
Length is imitated, longer fixing screws can be selected so that the connection of framework and back box is more firm.In general, inside back box
Space increases, and is conducive to radiating, it is understood that there may be resonator problem, but has above-mentioned screwed hole 110 to exist, and will not generally empathize
Chamber, is more preferably to solve the problem, can targetedly set perforate on the side wall of back box 11.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, and is familiar with
The those skilled in the art should be understood that the present invention includes but is not limited to accompanying drawing and interior described in embodiment above
Hold.The modification of any function and structure principle without departing from the present invention is intended to be included in the scope of claims.
