Abstract
The utility model discloses a kind of snap close, comprise pedestal, the locking device connecting pedestal and handle, round base medial recess, surrounding forms annular projection, described recess surface is established by connection locking device circular protrusions, and described locking device is cylindric, and top arranges one piece of location piece, its side arranges one groove, and described bottom portion of groove is arc; Locking device can bear the pressure that part bolt bears, prevent from not tightening because of bolt causing draw-in groove to be dislocated; Location piece and locking device eccentric setting, be convenient to fix when rotating, easy to use.
Description
Technical field
The utility model relates to a kind of solid a kind of snap close of guide pump.
Background technique
Guide pump lid existing at present is generally connected by the mode of draw-in groove fitted bolt, because guide pump internal pressure is comparatively large, needs pump cover to rotate to construction bolt during fixed position, but once bolt is not tightened, very easily cause draw-in groove to damage, even rupture, operation inconvenience.
Model utility content
The purpose of this utility model is to provide a kind of snap close, installs and rotates to fixed position, be inserted and rotated by snap close fixing until pump cover, strengthens join strength, prevents accident.
A kind of snap close that the utility model proposes for its technical problem of solution, comprise pedestal, the locking device connecting pedestal and handle, round base medial recess, surrounding forms annular projection, described recess surface is established by connection locking device circular protrusions, and described locking device is cylindric, and top arranges one piece of location piece, its side arranges one groove, and described bottom portion of groove is arc.
The recess width of locking device side is no more than the half of its cylindrical structure height, and the arc shaped surface minimum point of bottom portion of groove is through the center of circle in locking device cross section; The location piece at locking device top is cylindrical structural, its diameter is no more than locking device section radius, be positioned at the top of described groove, during use, first screwed by pump cover, the through hole covered with rear catch self-pumping is inserted and rotated, the groove of locking device is gone to immovable point, once bolt is not tightened, the pressure that bolt is born born by locking device, prevents draw-in groove from dislocating and damage pump cover.
Pedestal extends in strip backward, and the cross section that described strip extends is through the center of circle in pedestal cross section, and extended spot rear portion connects handle, and unitary design prevents fracture.
Location piece and locking device eccentric setting, be convenient to fix when rotating.
The utility model has the advantage of, locking device can bear the pressure that part bolt bears, prevent from not tightening because of bolt causing draw-in groove to be dislocated; Location piece and locking device eccentric setting, be convenient to fix when rotating, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with diagram and specific embodiment, setting forth the utility model further.
As shown in Figure 1, a kind of snap close, comprise pedestal 1, the locking device 2 connecting pedestal and handle 3, round base 1 medial recess, surrounding forms annular projection, and described recess surface is established by connection locking 2 device circular protrusions, described locking device 2 is in cylindric, top arranges one piece of location piece 4, and its side arranges one groove, and described bottom portion of groove is arc.
The recess width of locking device 2 side is no more than the half of its cylindrical structure height, and the arc shaped surface minimum point of bottom portion of groove is through the center of circle in locking device 2 cross section; The location piece 4 at locking device 2 top is cylindrical structural, and its diameter is no more than locking device 2 section radius, is positioned at the top of described groove.
Pedestal 1 extends in strip backward, and the cross section that described strip extends is through the center of circle in pedestal 1 cross section, and extended spot rear portion connects handle 3.
Location piece 4 and locking device 2 eccentric setting.
