Therefore, inventor of the present utility model needs a kind of new technology of design badly to improve its problem.
Utility model content
The utility model is not tight in order to solve the colligation of prior art coil, and outer stay inserts the problem do not entered, and provides a kind of assembly structure of single dovetail groove cushion block.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of assembly structure of single dovetail groove cushion block, comprise cushion block and outer stay, described cushion block comprises cushion block body, the middle part of described cushion block body is one for the cavity of accommodating described outer stay, described cushion block body side is provided with single dovetail groove mechanism, relative opposite side is provided with socket mechanisms, and described outer stay is rectangular structure, and itself and described socket mechanisms and described single dovetail groove mechanism match.
Preferably, described single dovetail groove mechanism comprises grafting outlet, the bilateral symmetry up and down that exports in described grafting is provided with fixed dam, described fixed dam comprises the first bayonet socket and the second bayonet socket, wherein said first bayonet socket end is rectangle, described second bayonet socket end is semicircle, and the tip spacing of two the first bayonet sockets is less than the tip spacing of two the second bayonet sockets.
Preferably, described socket mechanisms comprises interface, is provided with grafting baffle plate in the bilateral symmetry up and down of described interface, and described grafting baffle plate is quadrant structure.
Preferably, described cushion block body and described socket mechanisms and described single dovetail groove mechanism one-body molded.
Preferably, described cushion block body is that insulating board is made.
Preferably, described outer stay is that insulating board is made.
Preferably, described outer stay is that laminated paper board is made.
Adopt technique scheme, the utility model at least comprises following beneficial effect:
The assembly structure of single dovetail groove cushion block described in the utility model, adopts single oat tail groove structure, and coil banding can be avoided not tight, and outer stay is inserted the phenomenon do not entered and occurred.And the second bayonet socket of single oat tail groove structure is to the upper end of cushion block body or lower concave end, end semicircular in shape, instead of the three-legged structure of traditional dovetail groove, not only can play same fixation, also can effectively prevent foreign matter from piling up at the second bayonet socket place, also be convenient to take out even if there is foreign matter to exist, improve the useful life of cushion block to a certain extent.
Accompanying drawing explanation
