Abstract
The utility model provides an anti-theft tightening screw, which is to arrange a horizontal cylindrical shaped concave hole and arrange a ball top-head pin that is corresponding and closely cooperated with the bolt concave hole; the pin after the nut is tightly connected with the bolt is inserted into the bolt concave hole to present tight cooperation and the ball top head of the pin is exposed. The anti-theft screw having a horizontal pin has good anti-theft properties and convenient application, which can be widely used in the industries such as electric power wire tower, communication wire, traffic road and bridge guard bar, chemical industry and machinery industry, which is a novel anti-theft screw.
Description
Technical field
The utility model relates to the fastening screw of a kind of connection or fixed object.
Background technique
In known technology, existing fastening screw mainly is made up of with being threaded screw bolt and nut.It is widely used in industries such as electric power, machinery, chemical industry, traffic and is used for the connection of object or fixing.But because existing screw bolt and nut can arbitrarily be dismantled after being fastenedly connected, no anti-theft feature, especially the screw of line of electric force tower and connection bar can be dismantled stolen, cause circuit to destroy, stolen the tearing open of screw of freeway guardrail, traffic such as guardrail along the river, communal facility and for example, from and easily cause a serious accident, jeopardize people's life safety, also bring heavy losses.
Summary of the invention
In order to overcome the deficiency of existing screw, the utility model provides a kind of improved fastening screw, makes it can prevent from effectively to dismantle arbitrarily without approval after connection is fastening, and anti-theft is strong, and is easy to use.
The technological scheme that its technical problem that solves the utility model adopts is: horizontal prefabricated cylindric shrinkage pool on the head lateral body of bolt, corresponding bolt shrinkage pool preparation have friction tight with it ball top formula pin, the anti-theft screw of the band lateral pin that consists of.During use, nut is connected with bolt, the fastening back of object is become drive fit to the pin intercalation in the shrinkage pool of bolt, and the ball top is exposed, make and to extract, and stop the nut dismounting without specialist tools.
Because band lateral pin formula anti-theft screw new structure has been adopted in the utility model design, it can prevent to pull down arbitrarily without approval after the screw connection is fastening effectively twists nut, have that anti-theft is strong, novel structure, design innovation, advantage such as easy to use, can be widely used in line of electric force tower, communication line, traffic road and bridge guardrail and industries such as chemical industry, machinery, be a kind of novel anti-theft screw.
Description of drawings
Fig. 1 is the utility model embodiment concrete structure figure.
Mark among the figure: 1 bolt, 2 nuts, 3 lateral pins.
Embodiment
Embodiment as shown in Figure 1, the utility model comprises: bolt 1, nut 2 and pin 3.On bolt 1 key head lateral body, be shaped on horizontal cylindric shrinkage pool, corresponding bolt shrinkage pool preparation has friction tight with it ball top formula pin 3, nut 2 with in the shrinkage pool of bolt 1, become drive fit to be connected pin 3 intercalations after bolt 1 is fastenedly connected, and expose the ball head of pin 3, prevent to screw off in order to stop nut 2.
Pin 3 of the present utility model or expose the pin of top for billiard table formula or frustum formula.
Claims (2)
1, a kind of antitheft type fastening screw of tearing open, it comprises bolt, nut, it is characterized in that also comprising pin (3), bolt is the bolt (1) that is shaped on the horizontal cylindric shrinkage pool of scarf pin (3) on the bolt head lateral body, pin (3) is a ball top formula pin, and nut (2) is fastenedly connected back pin (3) drive fit embedding with bolt (1) and is connected in the horizontal shrinkage pool of bolt (1) and exposes the ball top.
