The utility model content
At the technical problem of above-mentioned existence, it is a kind of simple to operate, easy to use that this utility model purpose is to provide, good airproof performance, the hand-held sphygomanometers right-hand man rotary air valve device that accuracy is high.
In order to achieve the above object, the technical solution adopted in the utility model is as follows: a kind of rotary air valve device of hand-held sphygomanometers, comprise watchcase, piece together medicated cap, the rotary air valve assembly, handle and inflatable ball, the rotary air valve assembly links to each other with watchcase by piecing together medicated cap, inflatable ball and handle are installed in rotary air valve assembly lower end, it is characterized in that, described rotary air valve assembly comprises rotary shaft, main valve body, regulate parts, main valve body is provided with centre bore and through-hole structure, rotary shaft is fixed in the centre bore, described adjusting parts comprise steel ball and spring, and described steel ball and spring are installed in the through hole of main valve body.
As a kind of improvement of the present utility model, described assembly medicated cap is fixedlyed connected with watchcase, the fixing medicated cap of piecing together makes user no longer need to unscrew or tighten the assembly medicated cap, thereby minimizing measuring operation, the loss of avoiding the repeatedly rotary manipulation of instrument and causing is pieced together medicated cap and is provided with the hole slot structure that is complementary with centre bore, and two shallow circular grooves that are complementary with the interior steel ball of through hole, shallow circular groove makes air valve when rotated, can be that unit is fixed in the groove with 180 ° all the time.
As a kind of improvement of the present utility model, described rotary shaft is hollow structure, centre bore on the described main valve body links to each other by rotary shaft with hole slot structure on piecing together medicated cap, main valve body is that carrier is connected on the watchcase with rotary shaft and assembly medicated cap, by rotary shaft valve component is linked together with piecing together medicated cap, make air valve when rotating arbitrarily, can not break away from watchcase.
As a kind of improvement of the present utility model, be provided with sealing ring between described rotary air valve assembly and the assembly medicated cap, to guarantee the air-tightness of valve component and watchcase.
Advantage of the present utility model is: by the design of steel ball and spring, make air valve stuck phenomenon can not take place when rotated, air valve connects stable; Secondly by the fixing medicated cap of piecing together is set, when left and right adjusting, user no longer needs to unscrew or tighten the assembly medicated cap, and regulative mode is simple, and is easy to use; The sealing of sphygomanometers has further been guaranteed in the use of sealing ring, measures accurately, and the instrument wearing and tearing are little, long service life.
