Abstract
The utility model relates to a valve magnetic lock which comprises a valve cover, a valve rod, a valve cover cap and a handle. Connectors are arranged on the valve cover cap and the handle. A steel pin groove is formed on the valve cover cap. A magnet is arranged at the bottom part of the steel pin groove. The magnet is sleeved in a spring. A steel pin is disposed above the spring. A recessed groove is formed on the valve cover. The handle is ring-shaped. At least one pair of mortise and relevant tenon are formed on the outer surfaces of the valve cover cap and the handle respectively, and the mortise and the tenon engage to each other. The opposite surfaces of a magnet arranged on the handle and the magnet arranged in steel pin groove have the opposite magnetic poles. The valve magnetic lock has the advantages of simple structure, reasonable design and easy use, and can effectively prevent the valve from being opened or closed abnormally.
Description
[technical field]
The utility model relates to a kind of lock, relates to the magnetic lock that a kind of valve is used or rather.
[background technique]
At present, under many situations, for preventing that valve from by people's unauthorised opening or close, having adopted the counter measure that multiple mechanical structure is set in the keying operating position of valve, as adopt the special-shaped operation tool etc. that opens and closes.The poor effect of this counter measure outside this structure is exposed to, obviously as seen, As time goes on, is easily made similar instrument Open valve by other people, also provides convenience for other people imitate the improper keying operation tool of manufacturing.
[model utility content]
The utility model purpose is to overcome the problem that exists in the above-mentioned technology, and a kind of simple in structure, reasonable in design, valve magnetic lock that overall cost is low is provided.
The purpose of this utility model is carried out by the following technical solutions.
The utility model is by valve gap, valve rod, bonnet cap and handle are formed, on bonnet cap and the valve rod connection set is arranged, connect by connection set, fix and transmission, bonnet cap is provided with at least one steel pin groove, the steel pin groove bottom is placed a magnet, magnet is placed in the spring, steel pin places on the spring, the steel pin external diameter is greater than the spring external diameter, be slightly less than steel pin groove internal diameter, valve gap is provided with groove, the internal diameter of groove is slightly larger than steel pin groove internal diameter, and under nature, steel pin partly submerges in the steel pin groove, remaining part then inserts in the groove on the valve gap, handle is annular shape, and the outside and handle of bonnet cap is provided with and is at least a pair of groove and corresponding with it projection, and groove and projection are identical mutually, the position of built-in magnet and number are corresponding one by one with steel pin groove position and number on the bonnet cap on the handle, and the opposing side of built-in magnet and steel pin groove internal magnet is a different magnetic poles on the handle.
The utility model structure is not exposed on the external world, can prevent unauthorised opening easily during use or close, more safer, practical than existing valve, be difficult for being made similar instrument Open valve by other people, also, other people provide convenience for imitating the improper keying operation tool of manufacturing.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
Wherein:
The 1----valve gap; The 2----valve rod; The 3----bonnet cap; The 4----handle; The 5----perforation; The 6----perforation; The 7----steel pin; 8----steel pin groove; 9----magnet; The 10----spring; The 11----steel pin; The 12----groove; 12 '----groove; The 13----groove; 13 '----groove; The 14----projection; The 15----projection; 15 '----projection; The 16----groove; 17----magnet.
[embodiment]
Below in conjunction with accompanying drawing the utility model is specifically described.
With reference to figure 1, the utility model is by valve gap 1, valve rod 2, bonnet cap 3 and handle 4 are formed, corresponding perforation 5 and perforation 6 are arranged on bonnet cap 3 and the valve rod 2, connect by steel pin 7, fix and transmission, the combination of perforation 5 and perforation 6 and steel pin 7 forms connection set, bonnet cap 3 is provided with steel pin groove 8, a magnet 9 is placed in steel pin groove 8 bottoms, magnet 9 is placed in the spring 10, steel pin 11 places on the spring 10, steel pin 11 external diameters are greater than spring 10 external diameters, be slightly less than steel pin groove 8 internal diameters, valve gap 1 is provided with groove 12 and groove 12 ', groove 12 equates with steel pin groove 8 internal diameters with the internal diameter of groove 12 ', under nature, steel pin 11 parts are submerged in the steel pin groove 8, remaining part then inserts in the groove 12 ', the bonnet cap outside is provided with groove 13 and groove 13 ' and projection 14, handle 4 is annular shape, which is provided with projection 15 and projection 15 ' and groove 16, and projection 15 and projection 15 ' matches with groove 13 and groove 13 ', groove 16 matches with projection 14, handle 4 built-in magnet 17, the position of magnet 17 and number are corresponding with steel pin groove 8 positions and number on the bonnet cap, and the opposing side of the built-in magnet 17 of handle 4 and magnet 9 is a different magnetic poles.
Working principle of the present utility model is:
When using handle, because the built-in magnet positions on the handle is corresponding with the magnet positions of steel pin groove bottom, it is again different magnetic poles, so principle of utilizing the magnet heteropole to inhale mutually, increase the suction of steel pin groove bottom magnet, so that the steel pin pressuring spring, and be inhaled in the steel pin groove, at this moment, steel pin no longer inserts the valve gap groove, can not block bonnet cap, therefore, bonnet cap can drive valve rod and rotate freely, after opening or closing, take away handle, steel pin just inserts in the valve gap groove under the effect of spring again, this moment, bonnet cap and valve rod can't rotate, and had reached to take precautions against the improper keying operation of valve.
The foregoing description is only just for clearer explanation the utility model.Can not carry out any restriction to the utility model protection domain according to the foregoing description.Protection domain of the present utility model is as the criterion with the scope of claims.Persons skilled in the art can be carried out suitable adjustment and distortion to the utility model under the prerequisite of the utility model essence spirit, to adapt to specific needs.
