Abstract
The invention discloses an anti-theft device for cables, which comprises an upper shell and a lower shell which is in hinge connection with the upper shell. When the upper shell and the lower shell are closed in a tubular shape; an anti-theft clip is arranged on the inner wall of the upper shell and comprises an elastic connecting rod and a retaining member arranged on the end part of the elasticconnecting rod; the bottom of the retaining member is provided with oblique meshed teeth. The invention has a smart and reasonable structure and convenient use, and is an anti-theft device for cablesto be widely arranged in cable sleeves with the anti-theft function.
Description
Technical field
The present invention relates to a kind of anti-theft device, particularly a kind of cable theft-prevention device that is arranged in the cable protecting pipe.
Background technology
Usually; the cable that is imbedded in the underground piping is directly to be sleeved in the cable protecting pipe; owing to do not take safeguard measure; make some lawless persons have an opportunity to take advantage of like this; these lawless persons utilize tools used in crime such as scissors to cut off cable and just protect behind two and can be easily cable to be released in the protecting pipe and steal copper cash in the cable to seek ill-gotten gains; their this illegal activities have greatly damaged the people's public interest, and national wealth is suffered a loss.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is ingenious, reasonable and easy to use and can prevent the cable theft-prevention device that cable is stolen by the lawless person to the invention provides a kind of structure.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of cable theft-prevention device, comprise upper shell that is sleeved in the cable protecting pipe and the lower house that is connected with the upper shell hinge, when this upper shell and lower house are closed in a tubular form, be provided with theft-prevention clamp in upper enclosure inner wall, described theft-prevention clamp comprises elastic link and is arranged on the locking member of elastic link end, and described locking member bottom is provided with the oblique tooth of stinging that cable is clamped.
In the present invention, described elastic link is made up of torsionspring and adjusting connecting rod.
In the present invention, described locking member and elastic link flexibly connect by connecting axle, have fastener to be inlaid in connecting axle and the upper shell outer wall is located locking member.
The invention has the beneficial effects as follows: during use, open, lower house, cable is put in this product, remove fastener, elastic link on the theft-prevention clamp is clamped cable under the effect of elastic reset power, again this product is advanced in the protecting pipe of cable, when the lawless person when cable one end is firmly pullled cable, cable then can to locking member bottom oblique sting applying frictional force and drive elastic link and moving downward of tooth, to go up when making locking member extruded cable line, lower house backs down, because it is last, lower house is sleeved in the protecting pipe, and and the gap between the protecting pipe is limited, when last, after lower house withstands protecting pipe, pull at cable more, stinging tooth and cable will be held tightlyer under the locking member gone up simultaneously, lower house also can with protecting pipe inwall extruding more tightly, make cable not stolen, played good antitheft effect by the lawless person.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation after the present invention opens;
Fig. 2 is the end view after the closure of the present invention;
Fig. 3 is the structural representation of the present invention when using;
Fig. 4 is the structural representation of the present invention when not using.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of cable theft-prevention device, comprise upper shell 1 that is sleeved among the cable protecting pipe b and the lower house 2 that is connected with upper shell 1 hinge, when this upper shell 1 and lower house 2 are closed in a tubular form, be provided with theft-prevention clamp 3 at upper shell 1 inwall, described theft-prevention clamp 3 comprises elastic link 4 and is arranged on the locking member 5 of elastic link 4 ends, and described locking member 5 bottoms are provided with the oblique tooth of stinging that cable a is clamped.
In the present invention, elastic link 4 is made up of torsionspring 41 and adjusting connecting rod 42, can regulate the length of self by regulating connecting rod 42, so that adapt to the cable of different thicknesses.
As shown in Figure 4, in the present invention, locking member 5 flexibly connects by connecting axle with elastic link 4, has fastener 6 to be inlaid in connecting axle and with upper shell 1 outer wall locking member 5 is located.
Operation principle of the present invention is: during use, earlier the upper shell 1 and the lower house 2 of alarm are opened, cable a is put in this product, then fastener 6 is extracted, elastic link 4 on the theft-prevention clamp 3 is clamped cable a under the effect of elastic reset power, this product is advanced among the cable protecting pipe b again, when the lawless person with cable a when the c direction is firmly pullled cable a, cable a to locking member 5 bottoms oblique sting applying frictional force and drive elastic link 4 and moving downward of tooth, to go up when making locking member 5 extruded cable line a, lower house 1,2 back down, because it is last, lower house 1, the 2nd, be sleeved in the protecting pipe b, and and the gap between the protecting pipe b is limited, when last, after lower house withstands protecting pipe b, pull at cable a more, stinging tooth and cable a will be held tighter under the locking member 5, go up simultaneously, lower house 1,2 also can with protecting pipe b inwall extruding more tightly, make cable a not stolen by the lawless person, played good antitheft effect, if with two these products by in it oblique sting tooth and put in the cable protecting pipe in the opposite direction after, no matter then whichaway draws cable a all can not pull it.
Structure of the present invention is ingenious, reasonable and easy to use, is a kind of cable alarm that plays antitheft effect in the cable protecting pipe that extensively is installed in.
