Embodiment 1

[0026] like Figures 1 to 4 As shown, the anti-theft nut includes an inner body 6 and an outer shell 2, the inner body 6 is provided with threaded holes, the inner side of the outer shell 2 is provided with some transverse grooves 22 and some vertical grooves 23, and the inner body 6 is provided with There are some rollers 13, and the rollers 13 are provided with some protrusions, and the protrusions cooperate with the transverse grooves 22, and the outer casing 2 can rotate around the inner body 6; the rollers 13 can change the direction of rotation, and the rollers 13 After the rotation direction is changed, the protruding part cooperates with the vertical groove 23, and the outer shell 2 drives the inner body 6, which also includes the motor. The inner body 6 is rotatably connected with a bracket 12, the roller 13 is arranged on the bracket 12, the bracket 12 is provided with a bevel gear 14, the inner body 6 is provided with a swivel 9, and the swivel 9 is Several protrud...

Embodiment 2

[0032] like Figure 5 , 6 As shown, a wrench includes a handle 20 and an opening 19, the opening 19 is provided with a third conductive sheet 21 corresponding to the first conductive sheet 4 and the second conductive sheet 5, and the handle 20 is provided with an encoder .

[0033] Through the cooperation of the encoder and the decoder, only the paired wrench can connect the motor to make it run.

[0034] When in use, pass the bolt 1 through the tower grounding pole 7, use a wrench to screw the present invention, connect the motor, and the swivel 9 rotates to drive the roller 13, so that the protrusion on the roller 13 corresponds to the vertical groove 23 on the casing 2, The direction of the current is controlled, and the motor is reversed so that the protruding portion on the roller 13 corresponds to the transverse groove 22 on the housing 2 .

Abstract

The invention provides a theftproof nut which is characterized by comprising an inner body and an outer shell, wherein threaded holes are formed in the inner body; a plurality of horizontal grooves and a plurality of vertical grooves are formed in the inner side of the shell; a plurality of rolling wheels are arranged on the inner body; a plurality of protruded parts are arranged on the rolling wheels; the protruded parts are matched with the horizontal grooves; the outer shell can rotate around the inner body; the rotation directions of the rolling wheels can be changed, and after the rotation directions of the rolling wheels are changed, the protruded parts are matched with the vertical grooves, and the outer shell drives the inner body. The theftproof nut also comprises a control device capable of controlling the rotation directions of the rolling wheels. By using the scheme, the nut is in a splitting manner, and the inner body and the outer shell are selected to transmit according to needs, so that the use is very convenient. When the theftproof nut is screwed tightly or loosened, the protruded parts are matched with the vertical grooves, the outer shell is screwed, and the inner body rotates along with the outer shell; in usual conditions, the protruded parts are matched with the horizontal grooves, and the inner body and the outer shell are separated, so that the theftproof function is realized.

Description

technical field [0001] The invention relates to the field of connectors, in particular to anti-theft nuts. Background technique [0002] Ordinary nuts are regular hexagons, easy to use with a wrench, and have poor anti-theft performance. Common nuts are used for the bolts at the connection of the ground electrode of the tower and the UT fixing bolts of the stay wires, which can be easily removed by criminals, resulting in poor grounding of the tower or loss of the protection of the stay wires. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above defects and provide an anti-theft nut with good anti-theft function. [0004] In order to solve the above problems, the technical solution adopted in the present invention is: [0005] The anti-theft nut is characterized in that it includes an inner body and an outer shell, the inner body is provided with threaded holes, the inner side of the outer shell is provid...
