The utility model content
The utility model technical matters to be solved is: provide a kind of under the situation that tester breaks down, can force to revert to the tire pressure depth tester of initial testing state.
For solving above technical matters; The technical scheme that the utility model is taked is: a kind of tire pressure depth tester; Comprise housing, display device, measurement mechanism and PCB circuit board; Said display device, measurement mechanism and PCB circuit board are located at said enclosure interior, and its key is: said enclosure interior also is provided with resets switch.
Improvement as the utility model: the said switch of reseting is located between said PCB circuit board and the said battery compartment; The one of which end is located on the said PCB circuit board; The other end then with said battery compartment on a circular hole match, said display device comprises eyeglass, said eyeglass is located on the said housing; Said display device comprises LCD, be located at the backlight below the said LCD, and said eyeglass covers above the said LCD.
Further improvement as the utility model: described measurement mechanism comprises PMU and sounding gear; Said sounding gear comprises and connects slide block, is connected slide potentiometer and the sounding rod that slide block connects respectively with said; Said slide potentiometer is located on the said PCB circuit board; Said connection slide block is connected with slide switch on being located at face-piece, and said PMU comprises the sensor storehouse that is installed in said shell end, and the side in said sensor storehouse is provided with air admission hole.
Can obtain following useful technique effect through implementing the utility model: the enclosure interior of the utility model is provided with resets switch; When running into certain catastrophic failure; For example slide switch has been got back to initial position; But the reading of measuring the back demonstration can't make zero, and can return to the initial testing state through triggering the described switch of reseting, thereby fix a breakdown.On the described circular hole of reseting on the battery compartment that switch is located at enclosure interior; When needs trigger described when reseting switch; Only need battery door be opened, the instrument with apicule triggers it again, and the reading of the last demonstration of LCD will make zero; To reset switch like this and be located at enclosure interior and not only be not easy to let the end user touch unintentionally, nor influence attractive in appearance.The eyeglass of the utility model is located on the housing, can not only get up to protect the effect of LCD, can also save the material of housing.The utility model is provided with backlight, and eyes were comfortable, not dazzling when backlight can not only make user's reading, and can also make user night still can reading clear.When the drawings degree of depth, connect slide block and can promote the variation that slide potentiometer produces electric signal, the PCB circuit board calculates the degree of depth of tire through the variation of electric signal, measures accurately.The side in the sensor storehouse of the utility model is provided with air admission hole; When needing the air pressure of drawings, only need air hole be connected with hole on the tire, the air pressure of tire is measured in the variation of the electric signal that pcb board is come through sensor storehouse biography; Simple to operate, convenient and swift.When the needs drawings degree of depth, be connected with slide switch on being located at face-piece because connect slide block, the user can directly launch sounding rod through slide switch; When not needing to measure again; Can pack up sounding rod through slide switch, thereby can protect sounding rod, avoid accidental damage.
