Abstract
The utility model relates to a nut, relates to an antitheft nut which is applied to field facilities, such as electric power systems, communication systems, highways and the like, in particular to an outer sleeve locked antitheft nut, which comprises a nut body and a protective outer sleeve. The outer sleeve locked antitheft nut is characterized by further comprising a pin, the nut body and the protective outer sleeve are respectively provided with a pore, and the pin is inserted into the pores of the nut body and the protective outer sleeve to be fixed. The nut is firmer in fixation of the nut body and the protective outer sleeve, and the nut cannot damage the fixation effect when not in use, thereby facilitating fastening of the nut.
Description
Technical field
The utility model relates to nut, relates to anti-theft nut, applies in the field facilities such as electric power system, communication system and expressway, and particularly a kind of overcoat locks the formula anti-theft nut.
Background technique
In the prior art, a kind of anti-theft nut is arranged, and it has nut body and outside protective coat, and protective coat is wrapped in the nut body outside, the gluing combination of nut body and protective coat, when tightening this nut, can use spanner, after acquiring a certain degree, will destroy adhesive-layer, because adhesive-layer destroys, it is just impossible to want to unload lower nut later on, and this is because nut body and protecting cover relatively rotate; The shortcoming that collapsing force with adhesive-layer is unpredictable, collapsing force is little even can destroy before use influences its performance.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned shortcoming, provide a kind of nut body and protective coat in conjunction with more firm, at this nut time spent nut body that can not destroy and the anti-theft nut of the combination between the protective coat---overcoat locks the formula anti-theft nut not.
The purpose of this utility model is achieved in that overcoat locks the formula anti-theft nut, comprise nut body and protective coat, it is characterized in that: further comprising a pin, have aperture on nut body and the protective coat, pin inserts combination in nut body and the protective coat aperture;
In order better to realize the utility model, end has the groove of tightening up above the described nut body, and the described groove that tightens up is a groove from light to dark along the nut tightening direction;
In order better to realize the utility model, described nut body inside also has groove, has antitheft steel ball or antitheft pin block in the groove;
The beneficial effects of the utility model are: such nut have nut body and protective coat in conjunction with more firm, this nut not the time spent can not destroy the effect of its combination, help tightening of nut.
Description of drawings
Fig. 1 is the structural representation that the utility model overcoat locks the formula anti-theft nut
Wherein, 1, nut body 2, protective coat 3, pin 4, tighten up groove 5, antitheft steel ball
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, overcoat locks the formula anti-theft nut, comprises nut body 1 and protective coat 2, it is characterized in that: further comprising a pin 3, has aperture on nut body 1 and the protective coat, and pin 3 inserts combination in nut body 1 and protective coat 2 apertures;
In order better to realize the utility model, described nut body upper end has the groove of tightening up 4, and the described groove 4 that tightens up is grooves from light to dark along the nut tightening direction;
In order better to realize the utility model, described nut body inside also has groove, has antitheft steel ball 5 or antitheft pin block in the groove;
Described nut body inside also has groove, has antitheft steel ball or antitheft pin block in the groove, and has the groove of tightening up on the described nut body, is prior art, does not repeat them here.
When using the utility model, turn outside protective coat, continue firmly to arrive to a certain degree, pin is twisted into two parts, and destroys the combination of nut body and protective coat, owing to used pin, collapsing force increases.
