Abstract
The utility model belongs to the technical field of mechanical connecting pieces and relates to a fastening structure of a detachable junction surface. The fastening structure comprises an upper plate and a lower plate arranged below the upper plate. A T-shaped hole is formed in the lower plate. A through hole, corresponding to the T-shaped hole, is formed in the upper plate which is provided with an installing hole vertically communicating the through hole, in which a pulling rod is arranged. A tapered wedge hole is formed in the pulling rod. A tapered wedge is formed in the installing hole. A tapered wedge surface at the front end portion of the tapered wedge is arranged in the tapered wedge hole in a matching mode. The installing hole is in threaded connection with a screw, the front end portion of which is connected to the rear end surface of the tapered wedge in a matching mode. The fastening structure of the detachable junction surface is effectively suitable for occasions with limited activity space for wrenches.
Description
Technical field
The utility model belongs to mechanical fastener technical field, relates to a kind of detachable junction plane fastening structure.
Background technique
At present, fastening generally the adopting of existing detachable junction plane is screwed or combines fixing with screw-nut.These two kinds are fixedly connected with major defect that mode exists is that the both ends of the surface of junction plane need to reserve the spanner space that screw fastening is used, just inapplicable to arranging conditional occasion in this plane.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of junction plane fastening structure simple in structure, ingenious, reasonably detachable is provided, and this structure can effectively be applicable to the conditional occasion of spanner activity space.
The technological scheme providing according to the utility model: a kind of detachable junction plane fastening structure, comprise upper plate and be placed in the lower plate of described upper plate below, be characterised in that: described lower plate is provided with T-shaped hole, on upper plate, be provided with through hole corresponding to described T-shaped hole place, on described upper plate, be also provided with mounting hole, and the described through hole of the vertical perforation of mounting hole, is provided with pull bar in described through hole, and pull bar is provided with slanting wedge hole; In described mounting hole, be provided with wedge, wedge front end cammed surface is equipped with in described slanting wedge hole, the described mounting hole screw that has also been threaded, and screw front end is connected on wedge ear end face.
As further improvement of the utility model, near the T-shaped hole of described lower plate, there is a technique through hole, pull bar can be placed in T-shaped hole by this hole, pull bar bottom stage face is resisted against on the step surface in T-shaped hole.
As further improvement of the utility model, described upper plate upper surface is provided with counterbore corresponding to through hole, and is provided with cover plate at this counterbore place.
As further improvement of the utility model, described screw body of rod front end is provided with groove, and wedge rearward end is provided with the boss in mating connection with described screw grooves.
The utility model compared with prior art, advantage is: the utility model for existing detachable junction plane due to adopt screw fastening connect or screw-nut be fastenedly connected, what exist need to reserve activity space and some occasion cannot reserve the problem in space to spanner, special design goes out the one reasonably detachable junction plane fastening structure that is skillfully constructed, and this structure is fastenedly connected by one group of cammed surface realization; Adopt screw and wedge to adopt groove to match with boss structure simultaneously, realize two parts and move together.
