Background

In China, the property and personal safety loss of public facilities can reach more than one hundred million yuan each year due to the connection looseness or the artificial theft and damage of the component joints in the mechanical department, and great influence is brought to the healthy operation of national economy. The anti-theft nut belongs to the latest product with excellent anti-theft performance in twenty-first century, and is mainly used for anti-loosening and anti-theft series products of connecting and fastening parts of mechanical components. The anti-theft nut is formed in one step by a cold pier without two processing steps, and the surface is hot-galvanized. The anti-theft nut is widely used for national electric power iron towers and signal iron towers. In the prior art, various anti-theft modes exist, for example, a nut is designed into a special nut which can only be rotated by a special tool, or an anti-theft pin is arranged in the nut, but the anti-theft nuts can be forcibly clamped by a pipe wrench type clamping tool to destructively disassemble the nut, and the anti-theft performance is poor.

SUMMERY OF THE UTILITY MODEL

The utility model provides a hexagonal ball formula antitheft nut that theftproof performance is good for overcoming the not enough of theftproof performance among the prior art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a hexagonal ball formula antitheft nut, includes nut body and theftproof circle, theftproof circle in the middle of be equipped with nut body assorted round hole, nut body and theftproof circle cup joint, the nut body on be equipped with a plurality of circular slot one, the theftproof circle on be equipped with a plurality of circular slot two, circular slot one and circular slot two one-to-one, form the cavity between corresponding circular slot one and the circular slot two, the cavity in be equipped with the connective bar, circular slot one is arranged in to some of connective bar, another part of connective bar passes the round hole and arranges in the circular slot two.

The anti-theft nut is divided into a nut body and an anti-theft ring, the nut body is sleeved with the anti-theft ring, a connecting rod is arranged between the nut body and the anti-theft ring, the connecting rod can be broken when receiving certain force, and the connecting rod can be made of plastic, wood and the like and can be broken when receiving certain torque. When the anti-theft nut is installed, the connecting rod is arranged between the nut body and the anti-theft ring, the nut body and the anti-theft ring are integrated, and the anti-theft ring is clamped by a tool to rotate, so that the nut body is driven to rotate, and the anti-theft nut can be installed. When the installation is accomplished, continue to rotate the theftproof circle, because the connective bar can break when receiving certain torsion, make not to connect between nut body and the theftproof circle, smooth between nut body and the theftproof circle, when the thief steals, because the connective bar disconnection, the theftproof circle can only be free rotation on the nut body, and can not drive the nut body rotatory, such design has reached the purpose that the theftproof performance is good.

Preferably, the nut body is internally provided with a plurality of blind grooves, the blind grooves correspond to the circular grooves I one by one and are communicated with the circular grooves I, the shapes of the blind grooves are deep in the middle, the two ends of the blind grooves are shallow, and the blind grooves are internally provided with locking mechanisms which are fixedly connected with the connecting rods.

Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description.

In the embodiment shown in fig. 1, a hexagonal ball type antitheft nut includes a nut body 1 and an antitheft ring 2, a circular hole 3 matched with the nut body 1 is arranged in the middle of the antitheft ring 2, the nut body 1 is sleeved with the antitheft ring 2, a plurality of first circular grooves 4 are arranged on the nut body 1, a plurality of second circular grooves 5 are arranged on the antitheft ring 2, the first circular grooves 4 correspond to the second circular grooves 5 one by one, a cavity 6 is formed between the corresponding first circular grooves 4 and the second circular grooves 5, a connecting rod 7 is arranged in the cavity 6, a part of the connecting rod 7 is arranged in the first circular grooves 4, and another part of the connecting rod 7 penetrates through the circular hole 3 and is arranged in the second circular grooves 5. As shown in fig. 2, a plurality of blind grooves 8 are formed in the nut body 1, the blind grooves 8 correspond to the first circular grooves 4 one to one and are communicated with the first circular grooves 4, the shape of each blind groove 8 is that the middle is deep, the two ends are shallow, and locking mechanisms are arranged in the blind grooves 8 and are fixedly connected with the connecting rods 7. The locking mechanism comprises a ball 9 and a spring 10, one end of the spring 10 is fixedly connected with the connecting rod 7, and the other end of the spring 10 is fixedly connected with the ball 9. As shown in fig. 3 and 4, the cross section of the nut body 1 is i-shaped, the nut body 1 is provided with an upper end surface 11 and a lower end surface 12, the upper end surface 11 of the nut body 1 is provided with an inclined surface 13, and the height from the inclined surface 13 to the lower end surface 12 is gradually reduced from the center close to the nut body 1 to the center far away from the nut body 1. As shown in fig. 5, the anti-theft ring 2 is hexagonal prism, the diameters of the upper end surface 11 and the lower end surface 12 of the nut body 1 are both smaller than the length of the opposite side of the anti-theft ring 2, the anti-theft ring 2 is located between the upper end surface 11 and the lower end surface 12 of the nut body 1, and the nut body 1 is sleeved with the anti-theft ring 2.

The antitheft nut is divided into a nut body 1 and an antitheft ring 2, the antitheft ring 2 is sleeved between an upper end face 11 and a lower end face 12 of the nut body 1, a connecting rod 7 is arranged between the nut body 1 and the antitheft ring 2, the connecting rod 7 can be broken when certain force is applied, and the connecting rod 7 can be made of plastic, wood and the like and can be broken when certain torsion is applied. When the connecting rod 7 is disconnected, the anti-theft ring 2 can only rotate on the nut body 1, and when the anti-theft ring is installed, the connecting rod 7 is arranged between the nut body 1 and the anti-theft ring 2, the nut body 1 and the anti-theft ring 2 are integrated, and the anti-theft ring 2 is hexagonal outside the hexagonal prism and is convenient to install. The anti-theft ring 2 is clamped by a tool to rotate, so that the nut body 1 is driven to rotate, and the anti-theft nut can be installed. When the installation is accomplished, continue to rotate theftproof circle 2, because the theftproof nut can't continue down to make torsion act on connective bar 7, connective bar 7 rupture makes and is not expected to connect between nut body 1 and the theftproof circle 2, and is smooth between nut body 1 and the theftproof circle 2, when the thief steals, because connective bar 7 breaks off, theftproof circle 2 can only be free rotation on the nut body, and can not drive nut body 2 rotatory, thereby prevent to steal, the theftproof performance is good. Meanwhile, a locking mechanism is arranged in the nut body 1, when the anti-theft nut is screwed on the stud, the ball 9 is located in the deepest part of the blind groove 8, the ball 9 does not interfere with the movement track of the external thread on the stud, when the anti-theft nut is disassembled, the ball 9 is forced to move to the shallowest part of the blind groove 8 by the resultant force of the external thread on the stud and the external thread on the stud under the action of the resultant force applied to the ball 9 by the spring 10, and the ball 9 interferes with the movement track of the external thread on the stud, so that the anti-theft nut cannot be rotated. Because the inclined plane 13 is arranged on the upper end surface 11, the stress of the tool is not facilitated, and a thief cannot directly unscrew the nut body 1 by using a forcible dismounting tool, so that a better anti-theft effect is achieved.
