Abstract
The present invention relates to a pipeline cable alarm. The pipeline cable alarm is characterized in that: the periphery of s housing is larger than the external diameter of the distributed cable pipeline; a plurality of openings arranged on the center hole circumference of the housing are respectively provided with slipper blocks; the slipper block is distributed on a sliding groove arranged on the housing; the slipper block is provided with inverted teeth which cause the cable to un-directionally pass on one side matched with the periphery of the cable; the slipper block is provided with a spring at the other side; the slipper block causes the inverted teeth to adhere on the external circumference by the elasticity action. The device has positive and obvious burglarproof effect; the device uses a plurality of slipper blocks; under the elasticity action, the slipper blocks are automatically pushed to the center; the inverted teeth on the slipper block cause the cable to forwards assemble; the cable will be tighter if pulling reversely so that the cable will not be drawn from any end, thereby achieving the burglarproof purpose. The device has advantages of low cost, convenient installation and excellent social application prospect.
Description
Technical field:
The present invention relates to mechanical field, especially relate to mechanical antitheft apparatus, particularly a kind of pipeline cable alarm.
Background technology:
In the prior art, do not find as yet to prevent the device that pipeline cable is stolen effectively.In all kinds of engineerings, the cable that is laid in the outdoor underground piping is stolen easily, after the two ends of cable are cut, just can the property of the people and country be sustained losses severely easily from an extraction.
Summary of the invention
The object of the present invention is to provide a kind of above-mentioned shortcoming that overcomes, can prevent a kind of pipeline cable alarm that pipeline cable is stolen effectively.
For achieving the above object, the technical solution adopted in the present invention is: this pipeline cable alarm, comprise that cover plate is by being bolted to above the housing, at housing, is furnished with cable in the set centre bore on the cover plate, it is characterized in that: the housing periphery is greater than the external diameter of institute's distribution cable pipe, is furnished with slide block respectively in several openings that on the above centre bore circumference of housing, are provided with, slide block fits on the chute set on the housing, slide block is in a side that matches with the cable periphery, be provided with the pawl that makes that cable can only unidirectionally pass through, slide block is furnished with spring in the another side, and slide block is close on the excircle of cable pawl under the elastic force effect of spring.
Described a kind of pipeline cable alarm is characterized in that: the above centre bore of housing is made as annular distance, is provided with 2-7 opening on annular distance.
Described a kind of pipeline cable alarm, it is characterized in that: described chute is located at respectively between the inner face of the bottom of housing and cover plate, make the upper/lower terminal of slide block fit in the chute respectively, be respectively equipped with alignment pin on upper and lower two bottom surfaces of each chute, alignment pin fits over respectively in the set location notch of slide block upper/lower terminal face.
The present invention's beneficial effect compared with prior art:
The present invention compared with prior art, its effect is actively significantly.This alarm utilizes many slide blocks, under the effect of spring force, pushes many slide blocks to center automatically, and the pawl on the slide block makes cable forward to put into, and reversely draws tighter and tighter.When at the two ends of exposing of a required segment pipe cable, install respectively one make the relative alarm of pawl after, cable can't be twitched from arbitrary end, thereby reach antitheft purpose.The simple cost of this apparatus structure is low, and is easy for installation, has good social application prospect.
Description of drawings:
Fig. 1 be among Fig. 2 A-A to view;
Fig. 2 be among Fig. 1 B-B to view.
Among the figure:
1. bolt, 2. cover plate, 3. cable, 4. pawl, 5. alignment pin, 6. housing, 7. chute, 8. spring, 9. slide block, 10. location notch, 12. annular distances.
Embodiment:
Describe the present invention in detail below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, pipeline cable alarm contains cover plate 2 and is fixed on above the housing 6 by bolt 1.In order to improve anti-theft effect, on cover plate 2, bolt head hole is made as shrinkage pool, when spiral shell inspection 1 is tightened prepare after, again cross recess on the bolt head or flat recess are polished.Be furnished with cable 3 in the set centre bore on housing 6, cover plate 2, housing 6 peripheries are greater than the external diameter of institute's distribution cable 3 pipelines; Centre bore on the described housing 6 is made as annular distance 12, on annular distance 12, be provided with 2-7 opening, present embodiment is provided with 3 openings on annular distance 12, be furnished with slide block 9 respectively in 3 openings that are provided with on housing 6 the above centre bore annular distance 12 circumference, and slide block 9 fits on the chute set on the housing 67.Described chute 7 is located at respectively between the inner face of the bottom of housing 6 and cover plate 2, the upper/lower terminal of slide block 9 is fitted over respectively in the chute 7, be respectively equipped with alignment pin 5 on upper and lower two bottom surfaces of each chute 7, alignment pin 5 fits over respectively in the set location notch 10 of slide block 9 upper/lower terminal faces; Slide block 9 is provided with the pawl 4 that makes that cable 3 can only unidirectionally pass through in a side that matches with cable 3 peripheries, and slide block 9 is furnished with spring 8 in the another side, and slide block 9 is close on the excircle of cable 3 pawl 4 under the elastic force effect of spring 8.
Installation process and operation principle:
During use,, install one respectively and make the relative alarm of pawl 4 at the two ends of exposing of a required segment pipe cable 3.During installation, with cable 3 two ends respectively by pawl 4 smoothly by allocating in the annular distance 12, and this alarm is fitted over outside the pipeline opening; When the arbitrary end at cable 3 spurs, because housing 6 peripheries are greater than the excircle of institute's distribution cable 3 pipelines, pipeline is buried under the ground fixing, therefore it is fixing relatively outward that a side of housing 6 is blocked in the mouth of pipe, and meanwhile, the pawl 4 on many slide blocks 9 in the housing 6 is under the effect of spring 8 elastic force, automatically push many slide blocks to center, pawl 4 on the slide block 9 makes cable forward to put into, and reversely draws tighter and tighter, can make the cable can't be from arbitrary twitch.
A kind of pipeline cable alarm of the present invention in the middle of practical application, can play antitheft purpose effectively, has good social effect.
