Abstract
The utility model discloses a kind of air valve safe locking handle, including three-way air valve, it is provided with U-lag in the handle of described three-way air valve, it is provided with bearing pin in described U-lag, the upper end of described bearing pin is inserted with plectrum, the lower end of described bearing pin is inserted in the groove of gear axle, and described plectrum is fixed by nut, and the upper end of described nut is provided with spring.This utility model is novel in design, simple in construction, and when three-way air valve handle reaches a certain gear, when plectrum is not mentioned, pulling handle cannot rotate, it is achieved that the function that safety is pinned, and prevents maloperation, reduces potential safety hazard.
Description
Technical field
This utility model relates to field of oil drilling, particularly relates to a kind of air valve safe locking handle.
Background technology
At present, general three-way air valve, when getting to a certain gear, owing to there is no locking device, when handle is by External Force Acting, easily it is moved, makes gear change, easy maloperation, there is potential safety hazard.
Summary of the invention
The purpose of this utility model is the problem above overcoming prior art to exist, it is provided that a kind of air valve safe locking handle, can avoid operation, reduce potential safety hazard.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is achieved through the following technical solutions:
A kind of air valve safe locking handle, including three-way air valve, it is provided with U-lag in the handle of described three-way air valve, it is provided with bearing pin in described U-lag, the upper end of described bearing pin is inserted with plectrum, the lower end of described bearing pin is inserted in the groove of gear axle, and described plectrum is fixed by nut, and the upper end of described nut is provided with spring.
As optimize, the groove of described gear axle is spherical.
As optimize, the upper end of described bearing pin is provided with screw thread.
As optimize, described plectrum passes described bearing pin, and the two ends of described plectrum are placed in the outside of described bearing pin.
The beneficial effects of the utility model are:
This utility model is novel in design, simple in construction, and when three-way air valve handle reaches a certain gear, when plectrum is not mentioned, pulling handle cannot rotate, it is achieved that the function that safety is pinned, and prevents maloperation, reduces potential safety hazard.
Accompanying drawing explanation
Accompanying drawing described herein is used for providing being further appreciated by of the present utility model, constitutes the part of the application, and schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 overall structure schematic diagram；
Fig. 2 is the profile of this utility model clamping structure.
Label declaration in figure: 1, three-way air valve, 2, bearing pin, 3, plectrum, 4, nut, 5, spring, 6, gear axle, 7, handle.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, this utility model is described in detail.
With reference to shown in Fig. 1, Fig. 2, a kind of air valve safe locking handle, including three-way air valve 1, it is provided with U-lag in the handle 7 of described three-way air valve 1, bearing pin 2 it is provided with in described U-lag, the upper end of described bearing pin 2 is inserted with plectrum 3, and the two ends of described plectrum 3 are placed in the outside of described bearing pin 2, and the upper end of described bearing pin 2 is provided with screw thread, the lower end of described bearing pin 2 is inserted in the ball recess of gear axle 6, and described plectrum 3 is fixed by nut 4, and the upper end of described nut 4 is provided with spring 5, for described plectrum 3 being played the function of reset.
When described plectrum 3 is lifted up, driving described bearing pin 2 to be lifted up, described bearing pin 2 departs from the ball recess on gear axle 6, and the handle 7 of three-way air valve 1 can be pulled；When a certain gear pulled by the handle 7 of three-way air valve 1, unclamp plectrum 3, the most described bearing pin 2 resets under the effect of described spring 5, described bearing pin 2 inserts the ball recess on described gear axle 6, the handle 7 of described three-way air valve 1 is stuck, and the handle 7 of the most described three-way air valve 1 cannot move by plate, plays the effect of safety lock, prevent maloperation, reduce potential safety hazard.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for a person skilled in the art, this utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
