Abstract
An anti-theft fastener belongs to the mechanically tightening technology field. The anti-theft fastener includes a screw with a nut, and a fan-shaped boss is arranged on the top of the nut. In the clockwise direction, the front side of the fan-shaped boss is vertical and the back side is outer bevel or outer arc, two vertical sides against the fan-shaped boss are parallel and form a miss distance between each other. The anti-theft fastener can not be disassembled by tools so as to provide with anti-theft feature, can be used on the antiglare shield fixing, the utility model is made of plastics, and thereby will not cause rust corrosion and pollution of the environment.
Description
Technical field
The utility model belongs to the mechanical fasteners technical field, relates to a kind of antitheft fixed block.
Background technique
Along with China's economy grows continuously and fast, expressway construction is also in continuous increase, for reducing land seizure, the track central partition adopts concrete guardrail to separate, the opposite car light can not exert an influence to the driver when needing the installation anti-dizzy device to guarantee meeting on the protective grating, guarantee traffic safety, avoid serious car accident.Antiglare shield uses bolt, the bolt that uses is dismantled easily now, antiglare shield is disassembled to be lost morely, and what use is metal bolts in a large number, the metal bolts easy-to-rust, running into sleety weather rust liquid flows on the body of wall of concrete guardrail, influence the attractive in appearance of guardrail, the bolt of corrosion is difficult for removing in concrete, needs to change if run into the antiglare shield damage, the boring that will be shifted influences integral layout and attractive in appearance.
The model utility content
The purpose of this utility model provides a kind of antitheft fixed block.
The utility model is realized above-mentioned purpose by the following technical solutions: antitheft fixed block, comprise the screw rod that has nut, the nut top is relatively set with fan-shaped projection, the leading flank of fan-shaped projection is a vertical surface along clockwise direction, trailing flank is outer inclined-plane or outer arced surface, two vertical side of fan-shaped relatively projection are parallel to each other, and the formation gap of staggering mutually.
Antitheft fixed block also comprises expansion cone, and the expansion cone upper end is provided with radial protrusion or convex edge.
Fan-shaped projection is provided with two.
The nut top is provided with fan-shaped projection in the utility model, the leading flank of fan-shaped projection is a vertical surface along clockwise direction, trailing flank is outer inclined-plane or outer arced surface, two vertical side of fan-shaped relatively projection are parallel to each other, and stagger mutually and form the gap, the vertical surface of fan-shaped like this projection forms two fulcrums, use the Flathead screwdriver clockwise direction to screw just and can bolt on, and counterclockwise nut is outer inclined-plane or outer arced surface, there is not fulcrum, can not tool using (word or Phillips screwdriver) counterrotating dismantle, therefore have anti-theft feature.Fixed block can by nonmetallic material for example plastics make, change antiglare shield as needs, can directly punch at former bolt position, the fixing invariant position of antiglare shield, guaranteed that former whole structure is constant, in addition, the fixed block that nonmetallic material are made can not influence the attractive in appearance of antiglare shield and protective grating because of sleet produces corrosion, this antitheft fixed block not only can be used for the fixing of antiglare shield, can also be widely used in fields such as other buildings, engineering.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a nut plan view of the present utility model.
Embodiment
As shown in Figure 1, 2, antitheft fixed block comprises bolt 2, expansion cone 4, the expansion tube 3 that has nut 1, nut 1 top is oppositely arranged two fan-shaped protruding 6, fan-shaped along clockwise direction protruding 6 leading flank 7 is a vertical surface, trailing flank 8 is an outer arced surface, two vertical side 7 of relative fan-shaped protruding 6 are parallel to each other, and stagger mutually and form the gap, expansion cone 4 is taper, the outside, upper end is provided with projection 9, expansion tube 3 tops are provided with the internal thread adaptive with bolt 2, and its middle part is provided with the cone shape hole suitable with expansion cone 4, and expansion tube 3 bottoms have spreading seam 5 vertically.
Fixed block by nonmetal raw material for example the plastics disposal molding make.
Claims (3)
1, antitheft fixed block, comprise the screw rod that has nut, it is characterized in that, the nut top is relatively set with fan-shaped projection, the leading flank of fan-shaped projection is a vertical surface along clockwise direction, trailing flank is outer inclined-plane or outer arced surface, and two vertical side of fan-shaped relatively projection are parallel to each other, and the formation gap of staggering mutually.
