Abstract
The utility model discloses a self-locking bolt for an elastic wedge. The self-locking bolt comprises a screw rod and a head arranged at one end of the screw rod, a mounting groove is arranged at the other end of the screw rod, the wedge connected with a spring is mounted in the mounting groove, the wedge is a falling wedge, and the upper surface of the wedge is inclined from the head to the other end face of the screw rod facing the axis of the screw rod. The bolt is automatically locked after mounted, a nut is automatically locked in a pop-up manner by the self-locking bolt for the elastic wedge after the wedge connected with the spring is connected with a part, the probability that the nut on the bolt looses and even falls off during use is effectively avoided, connecting stability and safety of the bolt are improved, and the solid joint efficiency of the part is improved.
Description
Technical field
The utility model relates to a kind of fastening piece, particularly a kind of resilient wedge self-locking screw.
Background technique
Bolt is by head and screw rod one type of conventional fasteners dimerous, needs to cooperate with nut, is used to be fastenedly connected two parts that have through hole.This Connecting format claims that bolt connects.As screwing off nut from bolt, can make these two parts separately again, be to belong to removably connect so bolt connects.Daily life with produce in be widely used in being connected of various parts.Certainly just because of the detachability of bolt, under a lot of situation, the nut of connection can take place loosening even come off because be in vibrating state for a long time; And bring unnecessary trouble setting to the user is potential safety hazard, so the screw rod with lock function miscellaneous has just appearred in bolt family, and bolt with holes and head bolt with holes etc. on screw rod for example; These bolts that manually are provided with are in use installed trouble, and installation efficiency is low, length consuming time; Cost of production is big, and element structure is complicated, has influenced to a great extent to use the efficient of installing; And the locking component of the self-locking screw of this structure separates use installation trouble with bolt.
Summary of the invention
For addressing the above problem; The utility model discloses a kind of resilient wedge self-locking screw; Behind union piece, realize automatic ejection locking with the wedge that is connected with spring to nut; Avoid the nut on the bolt that probability loosening even that come off in use takes place effectively, improved bolted steadiness and Security, improved the affixed efficient of part.
The disclosed resilient wedge self-locking screw of the utility model; Comprise screw rod and the head that is arranged on screw rod one end; The other end of screw rod is provided with mounting groove; The wedge that is connected with spring is installed in the mounting groove, and wedge is a Falling Wedge, and the upper surface of wedge is tilted to the axial direction of screw rod by the other end end face of head to screw rod.
A kind of improvement of the disclosed resilient wedge self-locking screw of the utility model, the other end of screw rod is provided with at least one mounting groove, and the wedge that is connected with spring is installed in the said mounting groove.
The disclosed resilient wedge self-locking screw of the utility model; Behind union piece, realize automatic ejection locking with the wedge that is connected with spring, avoided the nut on the bolt that probability loosening even that come off in use takes place effectively, improved bolted steadiness and Security nut; Improved the affixed efficient of part; Also improve the fastening efficient of bolt simultaneously effectively, reduced the cost of production of producing consuming time and bolt, improved the fastening effect of part simultaneously effectively.
Description of drawings
The structural representation of Fig. 1, the disclosed resilient wedge self-locking screw of the utility model.
Accompanying drawing is indicated tabulation:
1, head; 2, screw rod; 3, wedge;
4, mounting groove
Embodiment
Below in conjunction with accompanying drawing and embodiment, further illustrate the utility model, should understand following embodiment only be used to the utility model is described and be not used in the restriction the utility model scope.Need to prove; Describe below the word " preceding " that uses, " back ", " left side ", " right side ", " on " and D score refer to the direction in the accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of specific features geometrical center.
As shown in Figure 1; The disclosed resilient wedge self-locking screw of the utility model; Comprise screw rod 2 and the head 1 that is arranged on screw rod 2 one ends, the other end of screw rod 2 is provided with mounting groove 4, and the wedge 3 that is connected with spring is installed in the mounting groove 4; Wedge 3 is a Falling Wedge, and the upper surface of wedge 3 is tilted to the axial direction of screw rod 2 by the other end end face of head 1 to screw rod 2.
A kind of improvement of the disclosed resilient wedge self-locking screw of the utility model, the other end of screw rod 2 are provided with at least one mounting groove 4, and the wedge 3 that is connected with spring is installed in the mounting groove 4.
During use; Behind the screw of wedge 3 through mounting hole on the part and nut, the spring support that is mounted in the groove is upspring, because the end near head of wedge 3 is big-elevation or right angle face; Thereby realized restriction, and then the self-locking of realization bolt is fixed to nut location.
The disclosed resilient wedge self-locking screw of the utility model; Behind union piece, realize automatic ejection locking with the wedge that is connected with spring, avoided the nut on the bolt that probability loosening even that come off in use takes place effectively, improved bolted steadiness and Security nut; Improved the affixed efficient of part; Also improve the fastening efficient of bolt simultaneously effectively, reduced the cost of production of producing consuming time and bolt, improved the fastening effect of part simultaneously effectively.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technological scheme of being made up of above technical characteristics combination in any.
