[0021] The present invention is further described below with reference to the accompanying drawings and embodiments:

[0022] A combined anti-theft screw for pipes, see Figures 1 to 4 , applied to the pipe body 1, the pipe body 1 is provided with a limit frame 2 on the outside, and the inside of both sides of the limit frame 2 is penetrated by an anti-theft screw body 3;

[0023] The anti-theft screw body 3 includes a screw head assembly 301 , a protective assembly 302 is provided on the top of the screw head assembly 301 , and a screw rod 303 is fixedly connected to the bottom of the screw head assembly 301 .

[0024] It is noteworthy that the screw head assembly 301 includes a screw head body 301a, a slot 301b is defined on the inner side of the middle portion of the screw head body 301a, a set of auxiliary holes 301c are symmetrically defined on the inner side of the surface of the screw head body 301a, and a set of slids 301d are symmetrically defined on the inner wall of the screw head body 301a. A stopper 301e is engaged within the slids 301d. The auxiliary holes 301c are connected to the slids 301d, and the stopper 301e is movably engaged within the slids 301d. The stopper 301e is in the shape of an inverted T. The provision of the slot 301b and the slids 301d in the present utility model effectively enables rapid engagement and assembly between the screw head body 301a and the protective assembly 302, thereby shielding the horizontal surface of the screw head body 301a, facilitating the concealment of the slot 301b for assisting in disassembly and assembly, and improving theft prevention. At the same time, the auxiliary holes 301c for assisting in adjusting the position of the stopper 301e are relatively small in diameter and therefore do not attract attention.

[0025] It is worth noting that the protective component 302 includes a protective cap 302a, and a clamping block 302b is fixed to the bottom of the protective cap 302a, wherein the protective cap 302a and the clamping block 302b are integrally formed, the protective cap 302a is hemispherical, and the clamping block 302b is hexagonal, and a group of movable blocks 302c are symmetrically engaged on both sides of the clamping block 302b, and a spring 302d is provided between the clamping block 302b and the movable block 302c. Furthermore, the movable block 302c forms an elastic structure with the clamping block 302b through the spring 302d, and the movable block 302c is partially engaged in the slide groove 301d and fits with the stop block 301e. In the present invention, the movable block 302c is squeezed into the interior of the protective cap 302a, which makes it easy to match the clamping block 302b into the clamping slot 301b. When the movable block 302c is flush with the slide slot 301d, the movable block 302c is partially popped out by the rebound force of the spring 302d and effectively engaged with the interior of the slide slot 301d, thereby limiting the clamping block 302b. At this time, only the smooth protective cap 302a is exposed on the top of the screw head body 301a, making it difficult to disassemble the anti-theft screw body 3.

[0026] Working principle: With the help of a hexagonal tool, the screw head body 301a and the screw rod 303 are rotated through the hexagonal slot 301b, which can be used in conjunction with the limit frame 2 to fix the pipe body 1. Then, the movable block 302c is squeezed into the interior of the protective cap 302a to facilitate the matching of the block 302b into the slot 301b. When the movable block 302c is flush with the slide 301d, the movable block 302c is partially ejected and engaged with the inside of the slide 301d by the rebound force of the spring 302d, thereby limiting the block 302b. At this time, the screw head body 301 Only the smooth protective cap 302a is exposed at the top of a to prevent others from maliciously disassembling the anti-theft screw body 3. When the staff disassembles the anti-theft screw body 3, they insert the operating needle into the auxiliary hole 301c and push the stop block 301e to move, so that the stop block 301e pushes the movable block 302c out of the screw head body 301a. At this time, the clamping block 302b is not restricted. The protective cap 302a can be gently squeezed outward to remove the protective assembly 302 as a whole, so that the clamping slot 301b is exposed, and the screw head body 301a and the screw rod 303 can be rotated by using a hexagonal tool.

[0027] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
