Description
Technical field
The utility model relates to a kind of valve, especially has the pipeline valve door lock of specific structure.
Background technique
Now, the air feed of many newly constructed houses, water supply control valve all are placed in outdoor public place.Can make things convenient for managerial department inquiry and control like this, but be pulled by child easily or, cause the trouble in the use by adult's practical joke.
Chinese patent CN2246226 number disclosed " heating installation register one's residence valve " patent (application number: 96212199.1), be that a cipher lock is installed on valve body, cipher lock surrounds the exposed parts of valve body bull stick, a locking closure is arranged on the cipher lock, have only going out the password of cipher lock, just can open locking closure, expose bull stick, valve is carried out open and close controlling.Chinese patent CN2527820 number disclosed " cipher lock valve " patent (application number: 02213002.0), be upwards to be provided with the rectangular projecting platform around the valve core link rod external part at the valve body that has valve now, the centre is provided with annular groove, compositions such as cipher lock comprises housing, mandrel, the pin clamp of living, rotating shaft, number plate, the pin of living, the rotating shaft underpart of cipher lock places in the annular groove and cooperates rotation fixing with the protruding bolt grafting of valve core link rod end; The number plate internal surface is trapezoidal and cooperates with the pin of living, and outer surface is provided with ten numerals of 0-9, axially offers groove in the same side of rotating shaft, number plate and mandrel, axially insert the pin of living along groove, live and sell upper end insertion housing, the lower end has the conical surface, with the conical surface groove fit of selling built in living in advance on the clamp.The deficiency of these two patents is: though can both protect the safety of pipeline valve, structure is too complicated, the cost of production height; Rainproof outlet capacity is poor, damages easily.
Summary of the invention
The purpose of this utility model is exactly that a kind of special pipeline valve door lock simple in structure will be provided, and makes pipeline valve can not pulled by child or by adult's practical joke, and simple in structure.
In order to achieve the above object, the special pipeline valve door lock that the utility model provides is except comprising housing, rotating shaft, spanner, axle sleeve, also comprise specific structure, wherein, axle sleeve is fixed in the housing, rotating shaft is inserted axle sleeve and is rotating with axle sleeve, and spanner is fixed on the rotating shaft upper end and can drives rotating shaft and rotates in axle sleeve, realizes the open and close of pipeline valve; Specific structure is made up of triangle rotary column, hinge, flexible pole; One circular groove is arranged in the rotating shaft, two axisymmetric through holes are arranged on the rotating shaft wall; A plurality of apertures corresponding with through hole are arranged on the sleeve lining; The triangle rotary column is placed in the circular groove of rotating shaft, can rotate with respect to rotating shaft under the key effect with corresponding vee gutter; Flexible pole has two, and the one end is by being hinged and connected to the bottom of triangle rotary column, and the other end passes in the aperture that inserts behind the through hole on the sleeve lining.When the utility model uses, under the key effect with corresponding vee gutter, the triangle rotary column rotates with respect to rotating shaft, drives flexible pole rotation and flexible at through hole, finally make in the flexible aperture of pole on sleeve lining into and out of, realize control to pipeline valve.
The special pipeline valve lockset that the utility model provides has positive effect: except comprising housing, rotating shaft, spanner, axle sleeve, also comprises specific structure, forms by triangle rotary column, hinge, flexible pole, and simple in structure; During use under key effect with corresponding vee gutter, the triangle rotary column rotates with respect to rotating shaft, drive flexible pole rotate also flexible at through hole, finally make in the flexible aperture of pole on sleeve lining into and out of, realization is to the control of pipeline valve, and is easy to use; Mechanical structure, cost of production is low, and rainproof outlet capacity is strong, and is not fragile.
Description of drawings
The utility model will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:
Accompanying drawing 1 expression schematic representation of the present utility model.
Structure shown in the accompanying drawing 1 comprises: axle sleeve 1, rotating shaft 2, triangle rotary column 3, hinge 4, flexible pole 5, aperture 6, through hole 7, circular groove 8.
Embodiment
The special pipeline valve door lock that the utility model provides is except comprising housing, rotating shaft 2, spanner, axle sleeve 1, also comprise specific structure, wherein, axle sleeve 1 is fixed in the housing, rotating shaft 2 is inserted axle sleeve 1 and is rotating with axle sleeve 1, spanner is fixed on rotating shaft 2 upper ends and can drives rotating shaft 2 and rotates in axle sleeve 1, realizes the open and close of pipeline valve; Specific structure is made up of triangle rotary column 3, hinge 4, flexible pole 5; One circular groove 8 is arranged in the rotating shaft 2, two axisymmetric through holes 7 are arranged on rotating shaft 2 walls; The corresponding aperture 6 of a plurality of and through hole 7 is arranged on axle sleeve 1 inwall; Triangle rotary column 3 is placed in the circular groove 8 of rotating shaft 2, can be with respect to rotating shaft 2 rotations under the key effect with corresponding vee gutter; Flexible pole 5 has two, and the one end is by cutting with scissors 4 bottoms that are connected triangle rotary column 3, and the other end passes through hole 7 backs and inserts in the apertures 6 on axle sleeves 1 inwalls.When the utility model uses, under the key effect with corresponding vee gutter, triangle rotary column 3 drives flexible pole 5 rotations and flexible at through hole 7 with respect to rotating shaft 2 rotations, finally make in the flexible aperture 6 of pole 5 on axle sleeve 1 inwall into and out of, realize control to pipeline valve.
