Abstract
The utility model relates to a jaw locking mechanism of a jaw-shaped ammeter, which comprises a jaw button arranged on one side of a casing. A rotating block arranged in the casing is coaxially connected with a gear knob of an ammeter. The end surface of the rotating block is provided with a smooth recess. A lever component is transversely hinged in the casing. One end of the lever component contactingthe end surface of the rotating block is linked and matched with the end surface, and a spring is arranged between the other end of the lever component and the inner wall of the casing. The other end of the lever component is positioned near the root of the jaw button to match to form a gear device of the jaw button. In the utility model, when the gear knob is screwed to a current gear, the jaw button can not be blocked, and a jaw can be opened by pressing the jaw button. When the gear knob is screwed to other gears, the root of the jaw button can be clamped, the jaw is locked, and the misoperation can be avoided. The utility model has the advantages of simple structure and convenient and reliable operation, and the user' safety can be raised when the user operates the ammeter.
Description
Technical field: the utility model relates to a kind of lock jaw mechanism of clamp on amperemeter.
Background technology: clamp on amperemeter not only can be surveyed electric current, goes back voltage-measurable, resistance etc., need open the jaw circle and live measured conductor when surveying electric current, surveys non-current value and need not open jaw.General clamp on amperemeter does not have the jaw catch means, also expansible of jaw when the gear knob is screwed into non-current gear such as voltage or resistance grade, like this may maloperation damage reometer, and may produce high pressure electric shock, poor stability when surveying big electric current with non-current gear.
Summary of the invention: at the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, and safe and reliable analog clamp on amperemeter is locked jaw mechanism.
The utility model comprises the jaw button that is located at housing one side, in housing, be provided with coaxial connection of gear knob of turning block and reometer, the end face of turning block is provided with smooth groove, in housing, also be laterally hinged with lever piece, the one end contacts with the turning block end face and is linked, be provided with spring between the other end of lever piece and inner walls, and this end is positioned near the formation jaw button gear device that cooperates of jaw button root.
When the gear knob was screwed into current gear, turning block and then rotated, and the end of lever piece is contacted with groove, and the other end of lever piece can be lifted by spring like this, and the jaw button can not be blocked, and can open jaw.When being screwed into other gear, lever piece and turning block contact jaw are elevated, and the other end falls to blocking jaw button root, and jaw pins, and avoids maloperation.Of the present utility model simple in structure, easy to use and reliable, the security when having improved user's operating current table greatly.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the main structure synoptic diagram of embodiment;
Fig. 2 is that Fig. 1 is at the A-A of jaw locking-in state cutaway view Amplified image;
Fig. 3 is that Fig. 1 is at the A-A of jaw unlocking condition cutaway view Amplified image.
Embodiment: as shown in the figure, jaw button 7 is located at housing 1 one sides, in housing 1, be provided with 3 coaxial connections of gear knob of turning block 2 and reometer, the end face of turning block 2 is provided with smooth groove 4, in housing 1, also be laterally hinged with lever piece 5, the one end contacts with turning block 2 end faces and is linked, and is provided with spring 6 between the other end of lever piece 5 and housing 1 inwall, and this end is positioned at, and jaw button 7 roots are neighbouring to be cooperated.Also be provided with stop column 8 in housing 1, lever piece 5 ends cooperate between jaw button 7 roots and stop column 8, can prevent like this that firmly lever piece 5 damages on time.Present embodiment is analog clamp on amperemeter, and in fact digital table also can use the utility model to improve safe reliability.
