Abstract
The utility model discloses a kind of peg fixture, the fixed head comprising peg and match with described peg, described peg comprises nail bar and the nail bar head with described nail masthead end threaded engagement, the bottom convex of described nail bar is provided with flange, the end face of described flange matches with the step surface in the counter sink be arranged on described fixed head, and convex is provided with snap fit on the outer circumference surface of described flange tail end, match with recessed draw-in groove on the inner peripheral surface of described counter sink bottom in the bottom surface of described snap fit.The setting of snap fit and draw-in groove, can effectively avoid peg to drop, the setting of flange, makes peg can bear larger pulling force, the setting of push rod head, is convenient to the assembling of peg, and the utility model structure is simple, drops after can effectively preventing peg sealing-off.
Description
Technical field
The utility model relates to machine tool accessory technical field, particularly relates to a kind of peg fixture.
Background technology
Peg fixture under prior art generally adopts in the through hole that directly to be plugged by peg on fixed head, then uses electric welding machine fastening, and the fixing peg of this kind of mode, is easy to cause peg directly to come off once sealing-off in Long-Time Service process.
Utility model content
It is simple that the purpose of this utility model there are provided a kind of structure, the peg fixture dropped after can effectively preventing peg sealing-off.
For reaching this object, the utility model by the following technical solutions:
A kind of peg fixture, the fixed head comprising peg and match with described peg, described peg comprises nail bar and the nail bar head with described nail masthead end threaded engagement, the bottom convex of described nail bar is provided with flange, the end face of described flange matches with the step surface in the counter sink be arranged on described fixed head, and convex is provided with snap fit on the outer circumference surface of described flange tail end, match with recessed draw-in groove on the inner peripheral surface of described counter sink bottom in the bottom surface of described snap fit.
Wherein, described flange is the cylinder being arranged on described nail bar bottom, and described cylindrical diameter is greater than the diameter of described nail bar.
Wherein, the macropore of described counter sink is arranged on the bottom surface of described fixed head, and described macropore matches with described cylinder.
Wherein, described snap fit is be convexly equipped in the annular flange flange on described cylinder outer circumference surface, the cross section setting triangular in shape of described annular flange flange, and the bottom surface of described annular flange flange is arranged down.
Wherein, the maximum outside diameter of described annular flange flange is slightly larger than the diameter of described macropore.
Wherein, described draw-in groove is the annular groove that annular is arranged on described macropore madial wall, and the maximum inner diameter of described annular groove is greater than the maximum outside diameter of described annular flange flange.
The beneficial effects of the utility model: the fixed head that the utility model comprises peg and matches with described peg, described peg comprises nail bar and the nail bar head with described nail masthead end threaded engagement, the bottom convex of described nail bar is provided with flange, the end face of described flange matches with the step surface in the counter sink be arranged on described fixed head, and convex is provided with snap fit on the outer circumference surface of described flange tail end, match with recessed draw-in groove on the inner peripheral surface of described counter sink bottom in the bottom surface of described snap fit.The setting of snap fit and draw-in groove, can effectively avoid peg to drop, the setting of flange, makes peg can bear larger pulling force, the setting of push rod head, is convenient to the assembling of peg, and the utility model structure is simple, drops after can effectively preventing peg sealing-off.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of peg fixture of the utility model.
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
In figure: 1. follow closely bar, 2. follow closely bar head, 3. flange, 31. snap fits, 4. fixed head, 41. draw-in grooves.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing 1 to Fig. 2
A kind of peg fixture, the fixed head 4 comprising peg and match with described peg, described peg comprises nail bar 1 and the nail bar head 2 with described nail bar 1 top threaded engagement, the bottom convex of described nail bar 1 is provided with flange 3, the end face of described flange 3 matches with the step surface in the counter sink be arranged on described fixed head 4, and convex is provided with snap fit 31 on the outer circumference surface of described flange 3 tail end, match with recessed draw-in groove 41 on the inner peripheral surface of described counter sink bottom in the bottom surface of described snap fit 31.
As preferred embodiment of the present utility model, described flange 3 is for being arranged on the cylinder of described nail bar 1 bottom, and described cylindrical diameter is greater than the diameter of described nail bar 1.
The macropore of described counter sink is arranged on the bottom surface of described fixed head 4, and described macropore matches with described cylinder.
Described snap fit 31 for being convexly equipped in the annular flange flange on described cylinder outer circumference surface, the cross section setting triangular in shape of described annular flange flange, and the bottom surface of described annular flange flange is arranged down.This structural design, can effectively avoid peg to drop,
As further preferred embodiment, the maximum outside diameter of described annular flange flange is slightly larger than the diameter of described macropore, described draw-in groove 41 is the annular groove that annular is arranged on described macropore madial wall, and the maximum inner diameter of described annular groove is greater than the maximum outside diameter of described annular flange flange.This structural design, effectively can ensure that snap fit and draw-in groove effectively engage.
As further preferred embodiment, in use, first nail bar is penetrated from the macropore bottom fixed head, snap fit and draw-in groove is finally made to match, and the step in lug upper surface and counter sink matches, and then nail bar head is threaded with nail bar, finally weld with fixed head bar will be followed closely.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
