SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides the antitheft screw, can effectively solve the problem in the background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the anti-theft screw comprises a screw head, wherein a screw rod is arranged at the bottom of the screw head, a rotating block is rotatably arranged on one side of the top of the screw head through a reserved groove, a cover plate is arranged at the top of the rotating block, a through hole is formed in the surface of one side of the top of the cover plate, a fixed rod is inserted into the through hole, a positioning groove is formed in the surface of the other side of the top of the screw head, and a glue bag is connected to the bottom in the positioning groove in a gluing mode; the glue bag is made of PVC, glue is injected into the glue bag, and when a large force is applied to the glue bag, the glue bag is damaged, so that the glue flows out.
Furthermore, an installation groove is formed in the peripheral surface of the bottom of the screw head, a spring is welded in the installation groove, and a pressing plate is arranged at the bottom of the spring; the pressure plate can be tightly contacted with the fixed plane under the action of the spring.
Furthermore, the bottom of the fixing rod is positioned in the positioning groove.
Furthermore, the top surface of the screw head is provided with a cross-shaped groove.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. through setting up apron, dead lever and glue package, the apron can rotate and cover to screwhead top, and the dead lever can insert the constant head tank and oppress the glue package to make the glue in the glue package flow, after this glue solidifies, it can be fixed in the constant head tank with the dead lever, thereby with the rigidity of apron, and because the apron has already covered the cross recess, so personnel can't use the screwdriver to dismantle this screw, so that this screw has certain theftproof performance.
2. Through setting up spring and clamp plate, this fix with screw is behind the appointed plane, and the clamp plate can be because of the atress with the fixed plane contact to make the spring retract, can exert certain reaction force to the clamp plate after the spring retracts, thereby make the laminating fixed plane that the clamp plate can be inseparable, and then prevent that the gap from appearing between screwhead and the fixed plane, corrode this part because of the threaded part through this screw of gap contact with in order to prevent impurity such as rainwater dust.

Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1-3, the anti-theft screw includes a screw head 2, a screw rod 1 is arranged at the bottom of the screw head 2, a rotating block 8 is rotatably installed at one side of the top of the screw head 2 through a reserved groove, a cover plate 7 is arranged at the top of the rotating block 8, a through hole 5 is formed in the surface of one side of the top of the cover plate 7, a fixing rod 6 is inserted into the through hole 5, a positioning groove 3 is formed in the surface of the other side of the top of the screw head 2, and a glue bag 11 is connected to the bottom of the positioning groove 3 in a gluing mode.
The outer peripheral surface of the bottom of the screw head 2 is provided with an installation groove 10, a spring 9 is welded in the installation groove 10, and the bottom of the spring 9 is provided with a pressing plate 12.
In this embodiment, as shown in fig. 1, 2, and 3, a plurality of springs 9 are provided, and when the springs are retracted, a relatively uniform reaction force can be exerted on the pressing plate 12, so that the pressing plate 12 can be in smooth contact with the fixed plane.
Wherein, the bottom of the fixed rod 6 is positioned in the positioning groove 3.
In the embodiment shown in fig. 1 and 2, after the fixing rod 6 is located in the positioning slot 3, the cover plate 7 is fixed on the top of the screw head 2.
Wherein, the top surface of the screw head 2 is provided with a cross-shaped groove 4.
In this embodiment, as shown in fig. 1, a person may turn the screw through the cross slot 4 using a screwdriver.
It should be noted that, the utility model relates to an anti-theft screw, in operation, personnel can fix the screw on a designated plane, at this moment, the clamp plate 12 can be stressed due to the contact with the fixed plane, thereby the spring 9 retracts, after retracting, the spring 9 can exert certain reaction force on the clamp plate 12, thereby the clamp plate 12 can be closely attached to the fixed plane, further a gap between the screw head 2 and the fixed plane is prevented, so that impurities such as rain and dust can be prevented from contacting the screw thread part of the screw through the gap to corrode the screw, next step, after the screw is fixed, personnel can rotate the cover plate 7 under the action of the rotating block 8, thereby the cover plate 7 covers the top of the screw head 2, at this moment, personnel can insert the fixing rod 6 into the positioning groove 3 through the through hole 5, and press the bottom of the fixing rod 6 to break the glue bag 11, thereby the glue in the glue bag 11 flows out, and, after this glue solidifies, it can be fixed in the constant head tank 3 with dead lever 6, and at this moment, the position of apron 7 can be fixed, and because apron 7 has already covered cross recess 4, so personnel can't use the screwdriver to dismantle this screw to make this screw have certain theftproof performance.
