Abstract
The utility model discloses a kind of enciphering valve special plastic keys, plastic hand wheel including being equipped with center deep gouge, opposite two sides are equipped with boss in the deep gouge of center, more than one magnet steel is equipped in the plastic hand wheel of center deep gouge bottom, it is characterized in that being installed with steel disc in the boss of two sides, the inner sidewall of steel disc is located on the inner sidewall of boss.The utility model has the advantages that not easy to wear, long service life, and encryption is good, is not easy to be imitated, and the safety of enciphering valve can be improved.
Description
Technical field
The utility model relates to a kind of enciphering valve private keys, especially the special plastic key for enciphering valve before table.
Background technique
Currently, the private key for enciphering valve before table, the handwheel including being equipped with center deep gouge is opposite in the deep gouge of center
Two sides be equipped with boss, in the handwheel of center deep gouge bottom be equipped with more than one magnet steel；Because its structure is complex,
Injection molding is passed through using plastic material；When in use, center deep gouge is placed on before table outside the protective case of enciphering valve, is pushed by magnet steel
The magnet steel to match in enciphering valve before table realizes unlock, then drives protective case rotation, enciphering valve able to turn on or off by boss；But due to
Handwheel is plastic material, easy to wear, and the time, slightly long boss abrasion rear center's deep gouge became arc, can not pass on torque, Bu Nengkai
Valve is opened, can only be scrapped, service life is shorter；In addition the magnet steel setting in handwheel is simple, easily it is imitated, so that enciphering valve easily quilt
It usurps.
Summary of the invention
The purpose of this utility model is In view of the above shortcomings of the prior art, to provide a kind of enciphering valve special plastic key
Spoon, it has the advantages that not easy to wear, long service life, and encryption is good, is not easy to be imitated, and the safety of enciphering valve can be improved
Property.
In order to achieve the above objectives, the enciphering valve special plastic key of the utility model, the plastics including being equipped with center deep gouge
Handwheel, opposite two sides are equipped with boss in the deep gouge of center, are equipped with more than one in the plastic hand wheel of center deep gouge bottom
Magnet steel, it is characterised in that steel disc is installed in the boss of two sides, the inner sidewall of steel disc is located on the inner sidewall of boss.
In use, the setting of steel disc so that two sides boss is not easy to be worn, can extend the service life of special plastic key
It is long；
The magnet steel is four and is arranged in rectangle as a further improvement of the utility model, on diagonal line
The polarity of two magnet steel is identical, and opposite with the polarity of two magnet steel on another diagonal line；From the quantity of magnet steel and setting side
Formula is not easy to be imitated so that the encryption of plastic key is good, and the safety of enciphering valve can be improved；
The steel disc is annular steel disc as a further improvement of the utility model,；Not only it is convenient for injection molding, but also can be improved
Whole wearability；
In conclusion the utility model has the advantages that not easy to wear, long service life, and encryption is good, is not easy to be imitated
System, can be improved the safety of enciphering valve.
Detailed description of the invention
Fig. 1 is the top view of the utility model embodiment.
Fig. 2 is the F-F cross-sectional view of Fig. 1.
Fig. 3 is the E-E cross-sectional view of Fig. 1.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1 to Figure 3, the enciphering valve special plastic key of the embodiment, the plastics hand including being equipped with center deep gouge 2
Wheel 1, opposite two sides are equipped with boss 3 in center deep gouge 2, and annular steel disc 4 is equipped in plastic hand wheel 1, annular steel disc 4
Inner sidewall is located on the inner sidewall of boss 3 and the inner sidewall of center deep gouge 2；It is equipped in the plastic hand wheel 1 of 2 bottom of center deep gouge
Four magnet steel 5 to 8 in rectangle setting, the polarity of two magnet steel 5 and 7 on diagonal line is identical, and another diagonal with being in
The polarity of two magnet steel 6 and 8 on line is opposite；
In use, the setting of annular steel disc 4 so that the inner sidewall of two sides boss 3 and center deep gouge 2 is not easy to be worn, can prolong
The long service life of long special plastic key；The quantity and set-up mode of four magnet steel 5 to 8 match in enciphering valve before table
Magnet steel must be not easy to be imitated using matched setting so that the encryption of plastic key is good, and the peace of enciphering valve can be improved
Quan Xing.
