Description
Technical field
The utility model relates to a kind of fastening piece, is specifically related to a kind of spring snap type Anti-detaching screw bolts and matching nut thereof.
Background technique
The fastening structure of present technology, a lot of mode adopting bolt and nut to coordinate has been come, namely nut screws in bolt in a direction and is fixed, and screws out to another way and can unclamp.By the nut of prior art for some large-scale apparatuses as on the field facilities such as electric power, highway, iron case and park sports equipment time, often absent-mindedness even comes off naturally as time goes by, thus accidents caused, cause any property loss, serious jeopardizes personal safety.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of spring snap type Anti-detaching screw bolts and matching nut thereof.
For achieving the above object, the technological scheme that the utility model is taked is:
A kind of spring snap type Anti-detaching screw bolts, comprise bolt body, the outside thread be located on bolt body, it is characterized in that: the through hole described bolt body being laterally provided with a circle, buckle is provided with in described through hole, described buckle upper end edge screw-in direction is provided with the projection of an inclination, and buckle lower end is provided with undergauge section, and described undergauge section is arranged with spring, described through hole outlet port is provided with spring collar, and described bolt body is provided with the step coordinating buckle.
As preferably, described undergauge section lower end coordinates with spring collar and is slidably connected, and described spring housing contacts and is connected in undergauge section and with spring collar.
As preferably, described spring collar is arranged in through hole by screw thread, spring collar be provided with for coordinate tighten in hexagonal groove.
Another object of the present utility model is to provide the matching nut of above-mentioned spring snap type Anti-detaching screw bolts:
A matching nut for spring snap type Anti-detaching screw bolts, is characterized in that: comprise nut body, is located at the internal thread on nut body, and described nut body inwall is longitudinally provided with at least one draw-in groove.
As preferably, the shape of described draw-in groove, size and direction and described projection are agreed with.
Above-mentioned a kind of spring snap type Anti-detaching screw bolts and matching nut thereof, compensate for the deficiencies in the prior art, be applicable to some large-scale apparatuses as field facilities such as electric power, highway, iron case and park sports equipments, prevent it from even coming off because long-time unmanned maintenance is relaxed naturally, accidents caused.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model bolt;
Fig. 2 is the structural representation of the utility model medi-spring collar;
Fig. 3 is the structural representation of the utility model nut.
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is described further.
As shown in the figure, a kind of spring snap type Anti-detaching screw bolts, comprise bolt body 1, be located at the outside thread 11 on bolt body 1, it is characterized in that: the through hole 3 described bolt body 1 being laterally provided with a circle, buckle 4 is provided with in described through hole 3, described buckle 4 upper end edge screw-in direction is provided with the projection 42 of an inclination, buckle 4 lower end is provided with undergauge section 41, described undergauge section 41 is arranged with spring 5, described through hole 3 outlet port is provided with spring collar 6, described bolt body 1 is provided with the step 2 coordinating buckle 4, described undergauge section 41 lower end coordinates with spring collar 6 and is slidably connected, described spring 5 is enclosed within to contact in undergauge section 41 and with spring collar 6 and is connected, described spring collar 6 is arranged in through hole 3 by screw thread 61, spring collar 6 be provided with for coordinate tighten in hexagonal groove 62.
A kind of matching nut of spring snap type Anti-detaching screw bolts, it is characterized in that: comprise nut body 7, be located at the internal thread 71 on nut body 7, described nut body 7 inwall is longitudinally provided with at least one draw-in groove 72, the shape of described draw-in groove 72, size and direction and described protruding 42 are agreed with.
When bolt tightening, screw-in direction is the plane of inclination of protruding 42, by extruding, buckle 4 is moved in through hole 3, can not cause stuck, and when bolt counterrotating, once draw-in groove 7 place being positioned at nut of protruding 42, due to the pressure of spring 5, the meeting of protruding 42 snaps in draw-in groove 7, prevents it from loosening.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection domain of the present utility model.
