Abstract

The invention relates to a pipeline valve lock. The pipeline valve lock comprises an upper cover, a lower cover, hinges and lock lugs. The upper cover and the lower cover are hinged through the hinges. The upper cover is arranged above the lower cover. A containing barrel communicated with the upper cover is arranged in the middle of the upper portion of the upper cover. The lock lugs are arranged in the middles of the outer walls of the other sides of the ends, hinged to the hinges, of the upper cover and the lower cover respectively. A lock hole of the lock lug on the upper cover corresponds to a lock hole of the lock lug on the lower cover. A lockset is buckled into the lock holes in the lock lugs of the upper cover and the lower cover. The pipeline valve lock is characterized in that a rain shielding cover is arranged on the upper cover and is arranged above the lock lug of the upper cover; telescopic plates are arranged inside the two ends of the upper cover and the two ends of the lower cover respectively; the telescopic plates slide on the two corresponding ends of the upper cover and the two corresponding ends of the lower cover; the telescopic plates are each in a semicircular tubular shape, end sealing plates with arc notches are arranged at the tail ends of the telescopic plates; screw holes are formed in the two ends of the upper cover and the two ends of the lower cover respectively, and screws are arranged on the screw holes. The rain shielding cover can shield sunshine and rainwater so as to protect the lockset, the length of the valve lock can be adjusted through the telescopic plates and the screws, the pipeline valve lock is suitable for fields and pipeline valves of different lengths.

Description

Pipe valve lock

Technical field

The present invention relates to pipeline valve technical field, specifically a kind of pipe valve lock.

Background technique

The valve of pipe-line system, owing to lacking protective measure, often can suffer wrongful opening and closing, pipeline liquid, the gas being usurped or misapply, can cause damage to owner, if poisonous and hazardous liquid, gas, security incident may be caused, to we providing structure pipeline valve lock device simple, easy to use, but still there is the shortcoming of the pipeline valve can not protecting lockset in the wild and different length can not be applicable in the patent that application number is " 200820219721.1 " " locking device for pipe valve "; Therefore, need to design a pipe valve lock of pipeline valve can protected lockset in the wild and be applicable to different length.

Summary of the invention

Technical problem to be solved by this invention is: provide a kind of pipe valve lock of pipeline valve can protected lockset in the wild and be applicable to different length.

The technical solution adopted in the present invention is: provide a kind of pipe valve lock, comprise upper cover, lower cover, hinge, lockset and lock ear, it is hinged that upper cover and lower cover pass through hinge, upper cover and lower cover are half-round tubular, upper cover and lower cover close cylindrical by hinge, on be covered on above lower cover, upper cover upper center is provided with an accommodating barrel connected with upper cover, described accommodating barrel upper end closed, upper cover and lower cover with the opposite side outer wall of hinge rounded end in the middle part of be equipped with lock ear, upper cover lock ear is corresponding with the lockhole of lower cover lock ear, lockset buckles in the lockhole of cover lock ear and lower cover lock ear, it is characterized in that: on described, be covered with the lid that keeps off the rain, keep off the rain and be covered on above cover lock ear, described upper cover and inside, lower cover two ends are equipped with expansion plate, and described expansion plate slides at the upper cover of correspondence and lower cover two ends, and described expansion plate is half-round tubular, and described expansion plate end is provided with the end-plate with arc gap, described upper cover and lower cover two ends are equipped with screw, and screw is provided with screw.

Described both sides, upper cover bottom and both sides, lower cover top are all with inside bending, and the edge at described bending part two ends is all with boss; Described expansion plate head end two bottom sides is with inside bent protrusion, and described boss and described bent protrusion acting in conjunction make expansion plate slide in upper cover and lower cover.

After adopting above structure, inventive pipeline valve in use, keeps the sun off with rainwater to protect lockset by the lid that keeps off the rain, and plays obstruction to the action managing to destroy lockset to a certain extent; By expansion plate and screw modulating valve door lock length, to ensure that pipe valve lock is applicable to the pipeline valve of different length; Be applicable to field to use, and be applicable to the pipeline valve of different length, easy to use, multiple functional.

Embodiment

Below in conjunction with drawings and Examples, the present invention is described in detail.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Fig. 6 and Fig. 7, inventive pipeline valve, comprise upper cover 1, lower cover 2, hinge 3, lockset 6 and lock ear 5, it is hinged that upper cover 1 and lower cover 2 pass through hinge 3, upper cover 1 and lower cover 2 are half-round tubular, upper cover 1 and lower cover 2 close cylindrical by hinge 3, upper cover 1 is located at above lower cover 2, upper cover 1 upper center is provided with an accommodating barrel 9 connected with upper cover, accommodating barrel 9 upper end closed, upper cover 1 and lower cover 2 with the opposite side outer wall of hinge 3 rounded end in the middle part of be equipped with and lock ear 5, it is corresponding with the lockhole that lower cover 2 locks ear 5 that upper cover 1 locks ear 5, lockset 6 buckles into upper cover 1 and locks ear 5 and lower cover 2 is locked in the lockhole of ear 5, upper cover 1 is provided with the lid 4 that keeps off the rain, the lid 4 that keeps off the rain is located at upper cover 1 and is locked above ear 5, upper cover 1 and inside, lower cover 2 two ends are equipped with expansion plate 7, and expansion plate 7 slides at the upper cover 1 of correspondence and lower cover 2 two ends, and expansion plate 7 is half-round tubular, and expansion plate 7 end is provided with the end-plate with arc gap, upper cover 1 and lower cover 2 two ends are equipped with screw, and screw is provided with screw 8.
