Abstract
A re-tightening theft-proof nut (nut for short) pertains to the category of mechanical products. First, a groove (3) with one end deep and the other end shallow is opened at the lateral wall inner hole in the middle of a metric system nut; then, a cylindrical bolt (4) is placed into the groove (3); an assembly pad (6) is plugged into the inner hole of the nut to prevent the cylindrical bolt (4) from dropping out; when a bolt (2) is screwed into the nut, the assembly pad (6) is pushed out from the inner hole. The nut has the functions of re-tightening, being theft-proof for being unable to be backed-off and loosen; since the bolt (4) is arranged in the middle of the groove inner, the theft-proof function is reliable, and as the parts is assembled on the floor and then being taken into high altitude, the utility model has the advantages of being safe and convenient.
Description
Technical field: the utility model belongs to the machinery product category, the more definite rescrewing of saying so, anti-theft nut.
Background technique: many electric power facilities of An Zhuaning and post and telecommunications communication facility all need to take the anti-theft measure of anti-dismounting in the open air.Now be used for fields such as electric power tower and post and telecommunications iron tower anti-dismounting facility and adopt anti-theft nut more.The anti-theft nut that adopts has two kinds at present:
(1) A type bolt-type anti-theft nut: this nut is driven the valley gutter of a up/down perforation on inner hole wall, inserts a latch from nut top in groove, and nut can't be unscrewed and antitheft.This nut can be extracted the theftproof performance poor reliability from the top because of latch; In addition, latch must be twisted good insertion again at nut, because of carrying out in the high-altitude, operates extremely inconvenience, and Security is also poor.
(2) Type B bolt-type anti-theft nut: this nut is upwards to drive a valley gutter in the bottom of inner hole wall, putting into latch in the nut lower direction groove has reached anti-latch and has been extracted by the people from the top, but when bolt vertically used, latch easily skidded off from the nut lower end and loses anti-theft feature; Latch also easily is stuck in the screw of fastener or in the endoporus of packing ring, so not only loses the rescrewing function that anti-theft feature also influences nut in addition.
Of the present utility model succeeding in developing solved the antitheft poor reliability of above-mentioned two kinds of anti-theft nuts effectively, and installation must be in high-lift operation, and poor stability uses inconvenient problem.Reached simple and reasonable, theftproof performance is reliable, effect easy to use.
Summary of the invention: the utility model description is as follows referring now to Figure of description 1,2,3 and 4: the utility model fills up (6) totally three parts formations by band groove nut (1), latch (4) and assembling.Wherein:
1. be with groove nut (1): these parts are the middle parts in the endoporus side of metric system nut, opening one laterally is: an end is dark, the groove that the other end is gradually shallow (Fig. 1-3, Fig. 3-3, Fig. 4-3), the darkest end is positioned at the left side (Fig. 4-3) at lateral cross section diameter position, band groove nut (1) endoporus middle part, to guarantee when nut dextrorotation is tightened, the latch (4) of putting into groove is inoperative, but left-handed when loosening when nut, when will moving to right, the latch (4) of then putting into groove (3) can not advance because of groove is gradually shallow, and then blocking nut can not be left-handed, so nut can't become flexible, and plays antitheft effect; The size of groove (3) and latch (4) are complementary.This part dimension and metric system bolt (2) size are complementary.
2. latch (4): the cylindrical parts that these parts are made by converted steel, size is complementary with groove (3) in the band groove nut (1).After these parts are vertically put into groove (3), be to stop the left-handed loosening parts of band groove nut (1).
3. (6) are filled up in assembling: these parts are by nonmetallic material, for example: plastics are made.Cross section is ring-type (Fig. 2-6), and size is complementary with the interior hole dimension of band groove nut (1).These parts are after latch (4) is packed in the groove (3) of band groove nut (1), and before not using, plug is packed into and played the parts that prevent that latch (4) from skidding off from groove in the endoporus of being with groove nut (1).When these parts screw in band groove nut (1) endoporus at bolt (2), then progressively from the endoporus of band groove nut (1), ejected by bolt (2).
Advantage of the present utility model:
1. because of the middle part of groove (3) at band groove nut (1), and laterally be that an end is dark, an end is gradually shallow, the latch of packing into (4) will assemble pad (6) again and fill in the endoporus of being with groove nut (1) and block latch (4) and drop out from groove (3).After screwing in bolt (2), assembling pad (6) is pushed out band groove nut (1) endoporus by bolt (2), latch (4) can clockwise rotate and rotates in groove (3) with nut, but when nut is rotated counterclockwise, latch (4) is because of being pressed against the gradually superficial part position of groove (3), so block nut and can not rotate counterclockwise, force nut (1) to advance to retreat loosening.The utility model is simple and reasonable from the above, and anti-theft feature is reliable.
2. latch of the present utility model (4) can be on the level land installs earlier by Fig. 2 and goes to the high-altitude to use again, so then handling safety, convenience.
Description of drawings:
1. the structure sectional view when Fig. 1 is the utility model user mode.
Fig. 2 be the utility model structural drawing just latch (4) groove (3) and the plug of putting into band groove nut (1) install assembling pad (6) dormant state sectional view.
3. Fig. 3 is a band groove nut sectional view.
4. Fig. 4 is the top view sectional drawing of putting in band groove nut (1) behind the latch (4).
Embodiment:
1. by specification accompanying drawing 1,2,3,4 and specification character narrate content are come out each component processing of the present utility model, and be stand-by.
2. pack into latch (4) in the groove (3) of band groove nut (1) and will assemble pad (6) and fill in to pack into and be with in the endoporus of groove nut (1) according to shown in Figure 2, block latch (4) and do not drop out.
3. bolt (2) is inserted in the hole of workpiece (5), and will be with groove nut (1) to be sleeved on the bolt (2), tighten; Simultaneously also will assemble pad (6) ejects from endoporus.The utility model of An Zhuaning can tighten up again and can not retreat loosening and antitheft like this.
