[0023] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0024] In order to solve the problems existing in the background technology, this application proposes the following technical solution: cable anti-theft device.

[0025] The specific technical solution includes a cable manhole 1, a cable body 2, and an anti-theft component 3. The cable manhole 1 has wire-passing holes 4 on both outer surfaces. The anti-theft component 3 includes a fixing ring 301, a positioning cylinder 302, a fixing wire 303, a buzzer 304, a guide hole 305, a push ring 306, a retaining ring 307, a limit spring 308, a push rod 309, a positioning rod 310, a push switch 311, a corresponding groove 312, a corresponding block 313, and an adhesive layer 314. The positioning cylinder 302 is located on the front outer surface of the fixing ring 301, the fixing wire 303 is located on one end outer surface of the fixing ring 301, and the buzzer 304 is fixedly installed on the outer wall of the positioning cylinder 302. The guide hole 305... 05 is set on the front outer surface of the positioning cylinder 302, the push ring 306 is set in the middle of the positioning cylinder 302, the retaining ring 307 is set on the rear outer surface of the push ring 306, the limiting spring 308 is fixedly installed between the push ring 306 and the positioning cylinder 302, the push rod 309 is set on the front outer surface of the push ring 306, the positioning rod 310 is fixedly installed on the inner surface of one end of the positioning cylinder 302, the push switch 311 is fixedly installed on the outer surface of one end of the positioning rod 310, the corresponding groove 312 is set in the middle of the push ring 306, the corresponding block 313 is set on the outer wall of the retaining ring 307, and the adhesive layer 314 is fixedly installed on the inner wall of the retaining ring 307. The anti-theft component 3 is used... The positioning cylinder 302 can be installed on both sides of the inside of the cable manhole 1 through the fixing ring 301, so that the cable body 2 passes through the positioning cylinder 302. During the penetration, the retaining ring 307 can be pasted to the outer wall of the cable body 2 through the adhesive layer 314. After the cable body 2 passes through the positioning cylinder 302, the retaining ring 307 is attached to the rear end of the push ring 306 and is limited by the corresponding block 313. If a thief pulls on the cable body 2 to steal it, the force on the cable body 2 will push the push ring 306 forward through the retaining ring 307. The push ring 306 will compress the limiting spring 308. At this time, under the action of the push ring 306, the push rod 309 will contact the press switch 311 and press. Switch 311 can activate buzzer 304 to sound an alarm. At the same time, under the limit of retaining ring 307, push ring 306 and limit spring 308, cable body 2 is not easy to be pulled out, which can prevent theft or prolong the time of cable theft, increase the difficulty of theft, and have a deterrent effect on thieves. It can improve the safety of cable body 2 and reduce the losses caused by theft. If the worker pulls on cable body 2, the fixing ring 301 can be removed, or the cable body 2 can be rotated to make the retaining ring 307 rotate and move by an angle so that the corresponding block 313 is aligned with the corresponding groove 312. At this time, the retaining ring 307 can be pulled out together to facilitate the extraction of cable body 2.

[0026] Furthermore, the fixing ring 301 is welded to the positioning cylinder 302, the positioning cylinder 302 and the guide hole 305 are integrally formed, the pushing ring 306 is movably connected to the positioning cylinder 302 through the limiting spring 308, the push rod 309 and the positioning rod 310 both pass through the middle of the limiting spring 308, the pushing ring 306 and the corresponding groove 312 are integrally formed, the corresponding block 313 and the retaining ring 307 are integrally formed. When in use, the retaining ring 307 can limit and fix the cable body 2, and can work with the pushing ring 306 and the limiting spring 308 to limit the displacement of the cable body 2, which can prevent theft or prolong the time of cable theft, increase the difficulty of theft, and have a deterrent effect on thieves.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0028] In use, the fixing ring 301 can be fixed to both sides of the inside of the cable manhole 1 using multiple sets of fixing screws 303, and the positioning cylinder 302 can be aligned with the wire hole 4. When the cable body 2 is laid through the positioning cylinder 302, the retaining ring 307 can be first pasted to the outer wall of the cable body 2 using adhesive layer 314. After the cable body 2 passes through the positioning cylinder 302, the retaining ring 307 is attached to the rear end of the push ring 306 and is limited by the corresponding block 313. If a thief pulls on the cable body 2 to steal it, the cable body 2 will be under force and will push the push ring 306 forward through the retaining ring 307. The push ring 306 will compress the limiting spring 308. At this time, the push rod 309 will contact the cable body 2 under the action of the push ring 306. Pressing switch 311 activates buzzer 304 to sound an alarm. Simultaneously, under the limiting effect of retaining ring 307, push ring 306, and limit spring 308, cable body 2 is not easily pulled out, which can prevent theft or prolong the time for cable theft, increase the difficulty of theft, deter thieves, improve the safety of cable body 2, and reduce losses caused by theft. If a worker pulls on cable body 2, the fixing ring 301 can be removed, or the cable body 2 can be rotated to make the retaining ring 307 rotate and move at an angle so that the corresponding block 313 is aligned with the corresponding groove 312. At this time, the retaining ring 307 can be pulled out together to facilitate the extraction of cable body 2.
