Abstract
The utility model relates to a communication pipe hole lock for preventing a pipeline from being stolen, which comprises a key, a lock cylinder, a blocking cover, a rotary stud, an expansion body and a conical nut. The conical nut and the rotary stud are respectively arranged in the expansion body and in threaded connection, the lower portion of the expansion body is provided with expansion teeth, inverted teeth are arranged on the expansion teeth, and clamping teeth are arranged on the conical nut. The key is rotated to enable the rotary stud to rotate, the conical nut buckled with threads is enabled to rise along with the rotation of the rotary stud, the conical surface of the conical nut extrudes the expansion teeth of the expansion body to open, and then the inverted teeth tightly extrude the inner wall of the pipeline. When the key can not be rotated, a pipeline opening is locked. The communication pipe hole lock is applied to the positions of underground communication pipelines and the like of telecom carriers, the pipeline opening is blocked so as to prevent water and theft, and most of parts are all made of plastics. Therefore, the communication pipe hole lock has the advantages of being simple in structure, safe and convenient to use, low in cost and the like, the pipeline opening must be closed by using a key special for the communication pipe hole lock, thereby avoiding the fact that optical fibers in the communication pipelines are easily stolen.
Description
Technical field
The utility model relates to the pore lock that uses in the pipe works, particularly a kind of communication pore lock that is used for the pipeline antitheft, specifically a kind of overall plastic mouth of pipe Sealed lock.
Background technology
It is iron or copper mostly that the pore lock that in pipe works, uses at present has a variety of, more common pore locks, and this kind pore lock corrosion resistance is poor, failure in a long time, and cost is high, and difficulty of processing is big.Adopt plastics pore lock though have, the same with above-mentioned iron or copper lock all do not have an anti-theft feature yet, and like this, ducted optical fiber possibly just be stolen.
Summary of the invention
In view of the deficiency that above-mentioned prior art exists, the utility model provides a kind of communication pore lock that is used for the pipeline antitheft especially.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of communication pore lock that is used for the pipeline antitheft is characterized in that; Comprise key, lock core, door, rotation double-screw bolt, expander, tapered cup nut, said tapered cup nut is provided with internal thread, and the rotation double-screw bolt is provided with external screw thread; Tapered cup nut places expander respectively with the rotation double-screw bolt and is threaded, and the expander inwall is provided with boss and retaining tooth, and the top of rotation double-screw bolt is provided with the outer; Center is provided with lock core hole in it, and boss and outer are matched in clearance, and said door is withheld on the rotation double-screw bolt through the retaining tooth; Lock core is provided with the lock tooth, and lock core is pressed in the lock core hole, and the front end of lock core and the inwall of lock core hole are tight fit; Be provided with on the key and lock the lock teeth groove that tooth is complementary, said expander bottom is made as bloated tooth, the tooth outer wall end of expanding be provided be used to block inner-walls of duct pawl; The tapered cup nut outer wall is provided with and is used to block tapered cup nut, the latch that it can not be rotated and match with bloated tooth.
The beneficial effect that the utility model produced is: this communication pore lock is applied to underground communication pipeline mouth of pipe places such as common carrier; The mouth of pipe is by shutoff not only waterproof but also guard against theft; Because most of parts all adopt plastic production, therefore, have simple in structure, safe and convenient to use, low cost and other advantages; Opening and closing the communication tube road junction must be with this private key of pore lock of communicating by letter, thereby the incident of avoiding the optical fiber in the communication pipe to be stolen easily takes place.

Fig. 3 is mounted in ducted the utility model sectional drawing.
Fig. 4 is the enlarged drawing of Fig. 3 A portion.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further description.With reference to Fig. 1, Fig. 2 Fig. 3 and Fig. 4, the communication pore lock that is used for the pipeline antitheft comprises key 1, lock core 2, door 3, rotation double-screw bolt 4, expander 5, tapered cup nut 6, and tapered cup nut 6 is provided with internal thread; Rotation double-screw bolt 4 is provided with external screw thread, and tapered cup nut 6 places expander 5 respectively with rotation double-screw bolt 4 and is threaded, and expander 5 inwalls are provided with boss 51 and retaining tooth 52; The top of rotation double-screw bolt 4 is provided with outer 41, and center is provided with lock core hole 42 in it, and boss 51 is a matched in clearance with outer 41; Door 3 is withheld on rotation double-screw bolt 4 through retaining tooth 52, and lock core 2 is provided with lock tooth 21, and lock core 2 usefulness instruments are pressed in the lock core hole 42; The inwall of the front end of lock core 2 and lock core hole 42 is a tight fit; Key 1 is provided with and lock the lock teeth groove 11 that tooth 21 is complementary, and expander 5 bottoms are made as six bloated teeth 53, each is bloated tooth 53 outer wall ends are provided be used to block inner-walls of duct pawl 54; Tapered cup nut 6 outer walls are provided with and are used to block tapered cup nut 6, two latches 61 that it can not be rotated and match with bloated tooth 53.
The communication pore lock that is used for the pipeline antitheft also comprises dust cap 7, and rotation double-screw bolt 4 bottoms are made as hollow cylinder, and this design can be saved raw material, and dust cap 7 is withheld the bottom in hollow cylinder.
The lock core 2 of the utility model, door 3, rotation double-screw bolt 4, expander 5, tapered cup nut 6 and dust cap 7 all adopt plastics forming, and key 1 adopts plastics or metal material processing moulding.
The operating principle of the utility model: the communication pore lock that is used for pipeline antitheft is that the internal diameter according to communication pipe designs, and wherein the mouth of pipe of pipeline 8 is blocked on the top of expander 5, when the mouth of pipe of locking pipeline; Key 1 is inserted in the rotation double-screw bolt 4, and the front end of lock core 2 is a tight fit with the inwall that rotates the lock core hole 42 in the double-screw bolt 4 in the rotation double-screw bolt 4, clockwise rotates key 1 and makes 4 rotations of rotation double-screw bolt; Owing to withhold door 3 on the rotation double-screw bolt 4, make its play that can not make progress, along with 4 rotations of rotation double-screw bolt; The tapered cup nut 6 that has screw thread to interlock is with it risen under the effect of latch 61 and bloated tooth 53; And can not rotate, the bloated tooth 53 of the taper surface extrusion expansion body 5 of the tapered cup nut 6 that constantly rises opens, and then pawl 54 jam-packed pipelines 8 inwalls of expander 5; When key 1 rotation is motionless; Be about to pipeline mouth of pipe locking, take off key, thereby realize anti-theft feature.
If open the mouth of pipe, must be with this key 1, in like manner; Rotate counterclockwise key 1 and make 4 rotations of rotation double-screw bolt,, the tapered cup nut 6 that has screw thread to interlock is with it descended along with 4 rotations of rotation double-screw bolt; Bloated tooth 53 retractions of expander 5; And then pawl 54 disengaging pipelines 8 inwalls of expander 5, the pore lock is whole loosening, can take off.
Because the utility model will rotate double-screw bolt and lock core is designed to the branch body structure, except lock core and key need satisfy the different communication operator otherwise designed, other parts are general part, therefore, have saved design and cost of manufacture.
