The screw rod 2 is connected with the screw head 1, and the lower end of the screw rod is provided with external threads for being matched with internal threads in a fixing hole on the fixing surface, so that the bolt is fixed on the fixing surface, and an object is fixed on the fixing surface or connection between the objects is realized through the bolt. The fixing surface in this embodiment may be a ground surface, a wall surface, a mounting surface of an object, or the like.

The conventional bolt is usually installed at the fixing hole and then reversely rotated to enable the bolt to be separated from the fixing hole, so that an article can be separated from the fixing surface, but the safety is low, and the article is easy to steal. Some manufacturers design some anti-theft bolts, but most of the anti-theft bolts cannot be removed or detached easily after being fixed in the fixing holes, so that the articles are difficult to replace, disassemble and repair.

Wherein, combine fig. 2 and fig. 4, the upper end shaping of screw rod 2 has the rotation chamber 3, the lower extreme shaping of screw head 1 has the turning block 4, the turning block 4 rotates to set up in the rotation chamber 3, and the independent rotation between screw rod 2 and the screw head 1, when initial state promptly, 360 degrees rotations in the rotation chamber 3 can be rotated to the turning block 4, and the rotation of screw head 1 can not influence the rotation of screw rod 2.

The rotating block 4 is connected with the rotating cavity 3 through the limiting block 7, and then the screw head 1 is connected with the screw rod 2, so that the screw rod 2 and the screw head 1 are connected into a whole, a user can drive the screw rod 2 to rotate by rotating the screw head 1, finally the whole bolt is enabled to rotate, the bolt is enabled to penetrate into or separate from the fixing hole, and the bolt is simply dismounted from the fixing hole.

When the limiting block 7 is not inserted into the first limiting hole 5 and the second limiting hole 6, the screw head 1 can not be rotated by a user to influence the screw rod 2, so that the screw rod 2 can not enter or leave the fixing hole by rotating the screw head 1, namely, after the limiting block 7 is pulled out by people, the screw head 1 on the upper side is rotated by a thief, the screw head 1 only idles, the bolt is kept motionless, the whole bolt can not leave the fixing hole, the bolt is kept to fix an article, the safety of the article is further ensured, and the anti-theft property of the bolt is improved.

When a user needs to disassemble the bolt, the novel bolt can be changed into a common bolt by inserting the limiting block 7 into the first limiting hole 5 and the second limiting hole 6, and the user only needs to apply force to the screw head 1, so that the bolt can integrally rotate, and the disassembly and assembly of the bolt in the fixing hole are completed. The bolt of this embodiment is also convenient for dismouting when realizing the theftproof function, and simple structure, convenient operation.

Further, referring to fig. 2, 4 and 5, in this embodiment, the shapes of the rotating block 4 and the rotating cavity 3 are both cylindrical, and the shapes of the rotating block 4 and the rotating cavity 3 are adapted. Thereby maximizing the space saving of the rotating block 4 and the rotating chamber 3.

As shown in fig. 4, the outer surface of the rotating block 4 is attached to the inner wall of the rotating cavity 3, the upper and lower inner wall surfaces of the rotating cavity 3 limit the up and down movement of the rotating block 4, and the inner peripheral surface of the rotating cavity 3 limit the lateral movement of the rotating block 4. Simultaneously, the cylindrical rotating block 4 and the rotating cavity 3 are matched, each side surface of the rotating block 4 can be close to the inner wall of the rotating cavity 3, the size of a gap between the rotating block 4 and the rotating cavity 3 is reduced, and therefore the offset space of the rotating block 4 in the rotating cavity 3 is smaller, and rotation is more stable.

Referring to fig. 2 and 4, a through hole 8 is formed on the upper side of the rotating cavity 3, and the through hole 8 communicates the rotating cavity 3 with the outer side of the screw 2; the lower surface of the screw head 1 is provided with a connecting block 11, and the connecting block 11 penetrates through the through hole 8 to be connected with the rotating block 4. Wherein the diameters of the through hole 8, the rotating block 4 and the rotating cavity 3 are sequentially increased. Therefore, the inner wall of the rotating cavity 3 can effectively limit the movement of the rotating block 4, and the rotating block 4 is prevented from being separated from the rotating cavity 3.

Further, the shapes of the limiting block 7, the first limiting hole 5 and the second limiting hole 6 may be circular or polygonal, in this embodiment, the limiting block 7, the first limiting hole 5 and the second limiting hole 6 are preferably circular, and further preferably square, and the shapes of the limiting block 7, the first limiting hole 5 and the second limiting hole 6 are adapted.

Referring to fig. 2, fig. 4 and fig. 5, when the shapes of the limiting block 7, the first limiting hole 5 and the second limiting hole 6 are square.

Namely, the middle parts of the first limiting hole 5 and the second limiting hole 6 are always overlapped, but when the edge parts of the first limiting hole 5 and the second limiting hole are misplaced, the limiting block 7 cannot be continuously inserted into the second limiting hole 6, so that the rotation association between the screw rod 2 and the screw head 1 cannot be completed, and the screw rod 2 and the screw head 1 independently rotate. When the first limiting hole 5 and the second limiting hole 6 are completely overlapped, the limiting block 7 can simultaneously penetrate through the first limiting hole 5 and the second limiting hole 6 to realize rotation association of the screw head 1 and the screw rod 2, and the screw head 1 can be rotated to integrally rotate the screw bolt.

Through square design, guarantee this embodiment theftproof and be convenient for dismouting function in, because stopper 7 are located the rotation center of turning block 4, stopper 7's atress also can be unanimous with turning block 4 to reduce stopper 7's effort, improve stopper 7's life.

Therefore, by the design of the first force application groove 9 and the second force application groove 10, a user can insert a tool into the first force application groove 9 and the second force application groove 10 to apply force, so that more labor saving is achieved. The first force application groove 9 may be in a shape of a straight line or a cross shape to adapt to a straight screwdriver and a cross screwdriver.

Example 2

As shown in fig. 6, the present embodiment is substantially the same as embodiment 1, and the difference is that the shapes of the limiting block 7, the first limiting hole 5 and the second limiting hole 6 are all circular, and the shapes of the limiting block 7, the first limiting hole 5 and the second limiting hole 6 are adapted. When the shapes of the limiting block 7, the first limiting hole 5 and the second limiting hole 6 are all round, the first limiting hole 5 is arranged on one side of the rotating block 4, and the second limiting hole 6 is arranged on one side of the rotating cavity 3. The centers of the first limiting hole 5 and the second limiting hole 6 are staggered with the rotation center of the rotating block 4, and the second limiting hole 6 is positioned on the motion track of the first limiting hole 5, namely, when the first limiting hole 5 rotates to a set position along with the rotating block 4, the first limiting hole 5 and the second limiting hole 6 are in overlapping communication. When the first limiting hole 5 is communicated with the second limiting hole 6, the limiting block 7 can penetrate through the first limiting hole 5 and the second limiting hole 6 at the same time to realize rotation association of the screw head 1 and the screw rod 2. Compared with embodiment 1, the first limiting hole 5 and the second limiting hole 6 in this embodiment are not always communicated, so that the possibility that sundries enter the second limiting hole 6 can be effectively reduced, and the possibility of blocking can be reduced while the cleanliness is improved.
