Abstract
The utility model relates to a locknut (1), comprising a cap nut (1) and apin (2). One or over one straight flute (4) whose cross-section is wedge-shaped are longitudinally arranged on the inside wall of the end of the cap nut (1) at which a bolt is screwed. The straight flute (4) which is longitudinal and clogged is provided from shallow to deep in the direction where the screw is screwed. The utility model is characterized in that The pin (2) is 'U'-shaped. The open end of the pin (2) is arranged in a straight flute (4) and is arranged towards the bottom of the straight flute (4). The pin (2) is'V'-shaped in the 'U' mode. The pin (2) can maintain the erected state through the supporting of two ends thereof. The height of the whole pin (2) can be made short. Therefore, the whole cap nut (1) can be made thin. Thus, the raw material consumption is saved. The mer weight is reduced. The transportation cost is decreased.
Description
Technical field: the utility model relates to the nut in the fastening piece, is exactly a kind of anti-lock nut that unloads in particular.
Background technique: existingly anti-unload lock nut and generally include nut and pin, as by the applicant in application on October 18th, 2002, on September 10th, 2003 bulletin, the patent No. is that the disclosed anti-lock nut that unloads is to screw at nut vertically to open one or symmetry on that end of bolt or another stomidium inwall and open two edges to be threaded into direction from shallow to deep obstructed in 02260835.4 the utility model patent " a kind of anti-lock nut that unloads "
Shape straight trough, and port also has a gasket recess that is used for placing packing ring on one week, pin insert at nut
In the shape straight trough, be plugged with a stopper in the nut bore, a packing ring is installed on the gasket recess above the stopper, the internal diameter of packing ring equates with the nut thread internal diameter, be provided with lug at stopper by a lid external side or the symmetrical both sides of one segmented column, bottom, and the lug correspondence is installed in
On the shape straight trough, pin is positioned at by lug
The dark recess of shape straight trough, stopper is a cylinder lid shape, and be provided with lug by a lid external side or the symmetrical both sides of one segmented column, bottom at cylinder lid shape stopper, by having a horizontal translot hole at the bottom of the cylinder of lug limit, and from top to bottom vertically have the two bar straight trough holes that are communicated with the translot hole at the two ends, translot hole, barrel upper edge of lug both sides, when having solved nut really and having screwed in bolton construction and installation stoppers gradually by gradually release, the lug of stopper can not be hampered by the ladder and the nut inner hole wall of nut shape straight trough, be convenient to the release gradually of stopper quilt, pin also is difficult for being stuck construction install convenience.But the nut of this structure and pin have enough length to avoid pin to lay across in order to make pin
Hinder the normal use of nut in the shape straight trough, the longitudinal length of straight trough needs the arc length greater than straight trough, so nut integral body is thicker, and the product raw materials consumption is bigger, has not only increased cost of material, has also increased cost of transportation.
Summary of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of consumption of raw materials the less anti-lock nut that unloads.
For achieving the above object, the technical solution that the utility model adopts is as follows: the anti-lock nut that unloads, comprise nut and pin, screw at the nut screw vertically offer on the inwall of that end of bolt one or one or more along be threaded into direction vertically not connecting from shallow to deep, cross section is the straight trough of wedge shape, it is characterized in that, described pin is " U " shape, and the opening end of pin is towards placing in the straight trough at the bottom of the straight trough.
Beneficial effect compared with prior art is: adopt " U " form " V " shape pin, the opening end of pin is towards placing at the bottom of the straight trough in the groove, pin can keep the erectility of pin by two end support, it is shorter that the height of whole pin can be done, therefore the integral body of nut also can be done thinlyyer, thereby the consumption that saves material has also alleviated monomer weight, has reduced cost of transportation.
The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment.
Description of drawings:
Accompanying drawing 1 is the utility model embodiment schematic representation;
Accompanying drawing 2 is the utility model embodiment partial structurtes sectional views;
Accompanying drawing 3 is embodiment's exploded view.
Specific embodiment: as shown in Figure 1, to existing anti-to unload lock nut 1 similar, present embodiment nut 1 is regular hexagon, the screw of nut 1 screws in vertically offers one or more along being threaded into direction from shallow to deep on the inwall of that end of bolt, vertically do not connect, cross section is the straight trough 4 of wedge shape, is generally 1～4, for stressed evenly for the purpose of, straight trough 4 preferably is provided with symmetrically, is symmetrical arranged two straight troughs 4 in the present embodiment, referring to Fig. 2; As Fig. 2, shown in Figure 3, present embodiment pin 2 adopts steel wire to be bent into " V " shape or " U " shape, and shape is wanted symmetry in order to avoid tilt, and highly is equal to or slightly less than vertical degree of depth of straight trough 4, and the opening end of pin 2 placed in the straight trough 4 towards 4 ends of straight trough; Stopper 3 is a cylinder lid shape, the employing plastics are made, external diameter and nut 1 internal diameter interference fit are in order to avoid come off, be provided with the lug 5 of axial trend near corresponding straight trough 4 places on the outer wall of the lid end one end, convex tendon by axial trend constitutes, convex tendon length is slightly less than straight trough 4 longitudinal lengths, the other end relative with the lid end on the lug 5 is the conical surface, the lid feather edge is provided with translot hole 7 near lug 5 places, the barrel of at least one side in lug 5 left and right sides is provided with the straight trough hole of longitudinally offering and be communicated with translot hole 76, be convenient to stopper 3 quilt releases gradually when being screwed into nut 1, referring to Fig. 2.Adopt the anti-lock nut 1 that unloads of present technique, for example for the nut 1 of M16, the height of nut 1 can be compared integral body with original nut and approach much below 8mm.
