Abstract
The utility model discloses a foot pedal switch structure for an electronic human body weighing balance, which comprises a resetting spring and a foot pedal switch. The utility model is characterized in that: a positioning switch groove is arranged inside the shell of the human body balance and the foot pedal switch is positioned in the positioning switch groove, and the resetting spring is arranged between the strained type weighing sensor and the foot pedal switch, and two ends are respectively contacted with the strained type weighing sensor and the foot pedal switch. The utility model is of simple structure, which can directly control the switch through the resetting spring without any transmission component.
Description
Technical field
The utility model relates to a kind of foot-switch structure of weighing scale, specifically is meant a kind of foot-switch structure of the Electronic Scales for Human Beings of weighing.
Background technology
The automatic foot-switch structure of the general employing of the Electronic Scales for Human Beings of weighing, promptly human body stands on the panel of weighing of weighing scale, because weight loads on the panel of weighing of scale body, the conducting automatically of foot-switch structure, weighing scale just can be weighed.
A kind of foot-switch structure of the prior art as shown in Figure 1 and Figure 2, this pedal control mechanism comprises back-moving spring 106, force-transmitting seat 104 and foot-switch 109, have positioning switch groove 111 in the housing 103, foot-switch 109 is installed in the positioning switch groove 111, foot-switch 109 comprises the switch keycap 113 that is convexly equipped with on switch base 112 and the switch base 112, forms the whole stepped structure of foot-switch thus; Also be provided with positioning bar 107 in the housing 103, back-moving spring 106 is enclosed within positioning bar 107 the insides; The other end of back-moving spring 106 and force-transmitting seat 104 contact; Force-transmitting seat 104 comprises power transmission muscle 110 and power transmission pedestal 105, power transmission muscle 110 and relative position place, switch keycap 113 place; Force-transmitting seat 104 and LOAD CELLS 102 contact.
When weight loads on the panel 101 of weighing of scale body, strain gauge load cell 102 moves to force-transmitting seat 104 directions, force-transmitting seat 104 moves to the direction of back-moving spring 106 simultaneously, compression reseting spring 106, the power transmission muscle 110 compression switch keycaps 113 of force-transmitting seat 104 simultaneously, make switch conduction, behind the switch conduction, force-transmitting seat 104 moves to the limiting stand terrace 108 of housing 103, and switch just no longer continues to be subjected to new additional force like this, that is to say that it is certain that switch is subjected to maximum elastic force pressure.
There is following shortcoming in above-mentioned foot-switch: owing to need the force-transmitting seat part between sensor and the back-moving spring, and need come push switch with actuating switch by the force-transmitting seat part, required parts are more, cause the foot-switch complex structure, increase manufacturing cost.
Summary of the invention
The purpose of this utility model provides a kind of foot-switch structure of simple in structure, a kind of Electronic Scales for Human Beings of weighing that can be by the direct manipulation of switches of back-moving spring.
Above-mentioned purpose of the present utility model realizes by following technical solution: a kind of foot-switch structure of the Electronic Scales for Human Beings of weighing, it comprises back-moving spring and foot-switch, it is characterized in that having the positioning switch groove in the housing of weighing scale, foot-switch is installed in the positioning switch groove, back-moving spring is installed between strain gauge load cell and the foot-switch, and its two ends contact with described strain gauge load cell and foot-switch respectively.
Foot-switch described in the utility model comprises the switch keycap that is convexly equipped with on switch base and the switch base, form the whole stepped structure of foot-switch thus, the surface of contact of switch base and switch keycap is a switch keycap flat surface, back-moving spring is placed on the switch keycap flat surface, the one end contacts with switch keycap flat surface, the other end contacts with strain gauge load cell, and back-moving spring has inside spin portion, and this inside spin portion and switch keycap are in the relative position place.
The end face of the positioning switch groove described in the utility model is spacing step surface.
When weight loads on the panel of weighing of scale body, strain gauge load cell moves to the direction of back-moving spring, compression reseting spring, the inside spin portion compression switch keycap of back-moving spring makes switch conduction, behind the switch conduction, strain gauge load cell moves to the limiting stand terrace of housing, switch just no longer continues to be subjected to new additional force like this, that is to say that it is certain that switch is subjected to maximum elastic force pressure.
Compared with prior art, the utlity model has following remarkable result:
1) need not any transfer components between sensor and the back-moving spring, make that the one-piece construction of foot-switch is simplified, reduce difficulty of processing, thereby reduce manufacturing cost;
2) owing to do not have transfer components between sensor and the back-moving spring, also make the power that produces when sensor and back-moving spring relatively move to be delivered to rapidly on the foot-switch, make foot-switch have the function of quick unlatching;
3) the utility model is directly controlled foot-switch by back-moving spring, the position centering of back-moving spring and foot-switch, and back-moving spring is directly to the foot-switch application of force, thereby avoids back-moving spring may produce the situation of inefficacy when controlling foot-switch pushing.
