Abstract
Existing calipers including electronic digital-display one, mechanical vernier one and mechanical pointer one utilize screw to lock slide and its operation is inconvenient and needs two hands. The caliper of the present invention utilizes self-locking button, rather than screw, to lock slide. Depressing the self-locking button can lock the slide onto the main rule, and after reading depressing it for the second time can unlock the slide for sliding freely. The caliper is convenient owing to its single-handed operation.
Description
The present invention relates to have the measurement mechanism of manual slide unit, particularly relate to all kinds of slide calliper rule such as explicit, mechanical cursor type of electron number and mechanical pointer.
Slide calliper rule can be measured multiple parameters such as length, the degree of depth, internal diameter and external diameter, are a kind of survey instruments that widely uses.Lock explicit, the mechanical cursor type of the electron number of selling and mechanical pointer slide calliper rule of existing market all are with lock screw the sliding pair chi to be locked on the main scale, need a hand-held chi during use, the another hand is tightened screw, and the slide calliper rule of this need bimanualness not only use inconvenience but also fundamentally just secondary chi can't be locked sometimes.For example: help another hand-held chi of testee just not have the pickpocket to twist screw on the other hand, measurement component in the crawl space of big machine inside can only put in a hand of holding chi for another example, and the another hand can't put in stubborn screw again.
Purpose of the present invention, will overcome when using slide calliper rule now locking device exactly needs the manual inconvenience of another, provides a kind of chi and secondary chi of locking held only to need slide calliper rule with the same hand operation.
Technical scheme of the present invention is: tighten the screw-type locking device with the replacement of locking press button locking device secondary chi is locked on the main scale.The formation of locking press button formula locking device is that interlock brake component on common locking press button switch, again this pushbutton switch is installed on the appropriate location of secondary chi, this position need be satisfied: 1, the vertical height from the main scale guide rail is suitable, make when pushbutton switch is in " pass " attitude that the brake component of interlock on it is pressed on to become on the main scale secondary chi is locked in locking attitude on the main scale; When pushbutton switch was in " opening " attitude, brake component and the main scale of interlock on it disengaged, and becomes the attitude of uncaging that secondary chi can be free to slide on the guide rail of main scale.2, the distance of handwheel is suitable on secondary chi, specifically, be installed in opposite one side of handwheel on the secondary chi when pushbutton switch, then require to be not more than 50mm from the distance of handwheel, like this, can operate handwheel and button simultaneously respectively with right hand thumb and forefinger and close close, and need not change the right hand other three refer to and palm hold the chi attitude; When pushbutton switch is installed in the same side of handwheel on the secondary chi, then require to be not more than 30mm from the distance of handwheel, like this, can operate handwheel and pushbutton switch in turn with right hand thumb, and need not change the right hand other four refer to and palm hold the chi attitude.3, this installation site makes pushbutton switch in the operation of "on" and "off", the brake component of interlock on it is along moving perpendicular to the direction of main scale slide guide rail, thereby guarantee that the component that brake component presses the moment of touching main scale or breaking away from main scale not to be parallel to guide rail acts on the main scale, secondary chi is the position with regard to can not change its measurement because of the reacting force slippage that is parallel to the guide rail direction of main scale and put in place the time also.Pushbutton switch in the locking press button formula locking device can be with the modal snap switch that has the snap switch of stirring the formula bistable structure or have reciprocating type bistable structure, at this moment brake component should avoid perfect rigidity ground to link to each other with shift knob, exceeds two transient overshoots outside the stable state scope so that absorb the stroke of stirring formula and reciprocating type snap switch button when state exchange.The shuttle button switch is a moving linearly, be installed in brake component on the shift knob and can press to or leave main scale perpendicular to main scale guide pass direction and realize the locking of secondary chi or uncage, be directly installed on the overshoot that can absorb button on the shift knob with the rubber-like brake component.The tumbler switch button is done movement in a curve, with brake component be directly installed on can not satisfy on the tumbler switch button vertical to the requirement of pressing to the main scale guide pass, for this reason, brake component is limited on the secondary chi moves in a groove perpendicular to the main scale guide pass, the tumbler switch button by the form of being movably hinged therewith brake component be connected, connect and to stir being movably hinged to be connected with spring and replacing of brake component in formula snap switch button and the chute, at this moment the two ends of spring are separately fixed in toggle switch button and the chute on the rigidity brake component, make the movement in a curve of button be transformed into the rectilinear motion of brake component in the chute by the flexibility of spring, and the rigidity brake component that slides of the transient overshoot can absorb conversion between snap switch button stable state by the retractility of spring time the and keeping is pressed to main scale suitable pressure is arranged.When switch is in " pass " attitude, the rigidity brake component head that slides can directly be pressed on the guide pass of main scale secondary chi is locked on the main scale, preferably the brake component head of rigidity directly is not pressed on the guide pass of main scale, in order to avoid damage guide pass, but be pressed on the guide pass indirectly by a spring leaf, this spring leaf is installed on the secondary chi, rigidity brake component head be not pressed in this above spring leaf the time this spring leaf also gently be pressed on the guide rail of main scale, thereby it is more steady to improve the repeatable accuracy of measuring to make secondary chi and main scale not have gap secondary chi slippage on main scale.Existing slide calliper rule all are equipped with this spring leaf on secondary chi, and can adjust the elasticity that this spring leaf contacts with the main scale guide rail under the attitude of uncaging with two screws, and the lock screw of existing slide calliper rule is pressed on this spring leaf.In the locking press button formula locking device of the present invention, the rigidity brake component in the chute of spring and tumbler switch button interlock also is pressed on this spring leaf that just had originally, and it is more rational transmitting the indirect braking of pressure by spring leaf.
Caliper with locking button of the present invention is compared with the screw caliper with locking that generally uses at present, locking device has been complicated a bit, but spring button switch adds a brake component, and cost increases compared with a screw and few, increases too many workload also can not for the assembling of slide calliper rule.Only need some work of the many a little dos of slide calliper rule manufacturer, make lock screw into the spring button switch, becoming from original need bimanualness only needs one-handed performance, brings great convenience just can for the user of slide calliper rule.
