Description

Fixed mechanism

Technical field

The utility model relates to the technical field of tools of mounting article, relates in particular to object is fixed in fixed mechanism in the groove of fixture.

Background technique

One or more objects are fixed in the technique for fixing of fixture, relevant with the body of fixed block and fixture.As object being fixed in the groove of fixture, its technique for fixing will design at the characteristics of fixed block body and groove body.Induction switch is fixed in cylinder body is example, will consider the heat radiation groove that utilizes the casing wall appearance to have induction switch to be made into the body that is complementary with the cylinder body groove, and induction switch is placed the groove of cylinder body, is fixed again.Certainly, the body of induction switch is made of plastic material, and plastic material itself has certain elasticity also can play certain fixation, but insecure, and therefore, fixed mechanism is indispensable.In the prior art, object is fixed in its structure more complicated of fixed mechanism of groove, operates more loaded down with trivial details, fixing not really firm.Market presses for supporting, simple in structure, the mechanism of fixing with groove easy and simple to handle fixedly time of a kind of and groove product.

The model utility content

The utility model is intended to the above-mentioned deficiency at prior art, and simple in structure, easy and simple to handle and the fixing fixed mechanism of groove fixedly the time are provided.

The utility model adopts following technological scheme to achieve these goals:

Construct fixed mechanism of the present utility model, comprise the groove that is arranged on the object that is fixed, be arranged at the blocks in the groove; Open system one notch, the sidewall of this notch break-through blocks at the diapire of blocks; One nut is set in notch, opens system one through hole facing to the roof of the blocks of this nut screw, a screw passes described through hole with nut is spirally connected outside the blocks roof, and screw is can be in nut clockwise or rotate counterclockwise; The pair of sidewalls of described notch is shaped on the inflection of gear right angle respectively, and the concavo-convex dislocation of this a pair of gear right angle inflection position is relative, and promptly the recess of this wall is relative with the protruding position to wall, and the protruding position of this wall is relative with the recess to wall; The a pair of outer wall of nut is shaped on outwardly directed convex edge, and the outside of this convex edge is curved, and the terminal point from the starting point of convex edge to the convex edge increases continuously along wide, and termination rectangular inflection in convex edge is drawn in to form protruding hook; Line segment between the straight line in the center of circle of the screw by nut and the intersection point of nut outer edge is that protruding hook place is the longest in gear right angle inflection place, is called the length of nut; Vertical with the length of nut be called the wide of nut; The protruding hook of nut is corresponding with the gear right angle inflection of the notch of blocks and be the state of keeping out, and carries out spacing with the form of keeping out to the rotation of nut.

Technique scheme is further elaborated:

The form of described groove is that the straight trough and the dovetail groove of neck shape joins, and the bottom is a dovetail groove, and top is that notch is a neck shape straight trough.

Have screwdriver slot on the screw terminal, be convenient to screwdriver turn screw.

Described blocks two side is plane, and the perpendicular distance between this two wall is the width of blocks, and its width is consistent with the width of the notch on groove top.

The width of the wide and blocks of described nut is consistent.

The thickness of nut outer ring is less than the height of dovetail groove.

Mechanism of the present utility model is as follows: when blocks when the notch of groove is positioned over the groove, there is the surplus space between the plane blocks sidewall and the dovetail groove sidewall of groove, at this moment, push nut down, nut also is arranged in this surplus space, and promptly nut is among the empty avoiding.If counterclockwise turn screw, the protruding hook of nut and the gear right angle inflection of blocks pocket side wall are collided, and nut can't be rotated by gear, have to the screw regression.Push moral more simultaneously, clockwise turn screw, at this moment nut is in the empty avoiding state, be in nut among the empty avoiding with the clockwise turn of screw, the convex edge of nut screws in dovetail groove, until colliding with the dovetail cell wall, and the downward pressure of the cell wall that is subjected to dovetail groove, nut is stuck and fixes.As seen, nut is when being subjected to downward pressure and turning clockwise, by the precession dovetail groove and fixing.

Fixed mechanism of the present utility model, operation is as follows during use:

1. screw is screwed in nut by the through hole on the blocks, it is full to allow nut be revolved by screw, and the protruding hook of nut and the gear right angle inflection on the blocks pocket side wall are collided, and at this moment, the broadside of nut is concordant with the broadside of blocks.

2. broadside is put in the groove from notch along groove with the blocks that the broadside of nut aligns.

3. push blocks downwards, with the clockwise turn screw of screwdriver, nut clockwise precession dovetail groove and fixing in empty avoiding.

4. if will take out blocks, counterclockwise turn screw when pushing, nut follow that a little rotates appropriate angle counterclockwise, and the convex edge of nut is screwed out dovetail groove, and fixed solution removes, and blocks just can take out groove.

The utility model is compared its useful effect with prior art and is: one, simple in structure being suitable for, by the gear right angle inflection that the protruding hook that is shaped on nut and blocks pocket side wall are shaped on, just blocks can be fixed in the groove with dovetail groove by rotary screw; Its two since nut on the convex edge by the precession dovetail groove, the convex edge is subjected to the clinching of dovetail cell wall and fixes, therefore, blocks and groove are connected firmly; Its three, easy to operate, the screw that turns clockwise slightly just is fixed, and is rotated counterclockwise screw slightly, and fixed solution is removed.
