Abstract
The utility model relates to equipment for the guaranteed repair and the detection of automobiles, particularly a tread ruler for automobiles. The utility model is composed of a tread ruler base, a row of pressure sensitive switches, a control circuit, a triggering mechanism and a protective rubber plate, wherein the pressure sensitive switches are evenly and tightly arrayed in the tread ruler base, the control circuit is matched with the pressure sensitive switches, the triggering mechanism is matched with the pressure sensitive switches and is arranged on the pressure sensitive switches for triggering the pressure sensitive switches, and the protective rubber plate is arranged on the upper part of the tread ruler base. The utility model solves the problem of parking detection, has simple structure, is not limited by surrounding work environment and fully solves various problems of photoactive tread rulers during use.
Description
Technical field
The utility model relates to automobile guarantee and checkout equipment, is specially a kind of automotive wheels carpenters square.
Background technology
The automotive wheels carpenters square is that equipment was used for measuring between the wheel wheel center distance in order to a kind of checkout equipment of subsequent detection step before the vehicle front locator value detected during the preparatory stage.At present known product generally adopts the optoelectronic scanning mode, its by in the place ahead of vehicle to wheel transversal scanning measure deflecting roller wheel center distance.But detect because the mode of optoelectronic scanning needs to stop in test process, so its process need expends the regular hour and then it is long to make whole front alignment value detect the station testing process, is unfavorable for detecting the requirement of streamline efficient quick.For a change this situation our factory has at first developed the photosensitive formula wheel of product carpenters square, its method of work is: the light activated switch that a row evenly arranges is set, when wheel when light activated switch passes through, trigger corresponding photosensitive switch motion, control circuit changes into the quick switch motion situation of change of this process the numerical value of deflecting roller wheel centre distance.Photosensitive formula wheel carpenters square has solved the problem of stopping and detecting, but owing to be that roller carpenters square light on every side guarantees operate as normal, light activated element just can't operate as normal when light is dark.Therefore must equip the floor light light source.Through using its still old a lot of problems: the machining precision height, the light-receiving window of easy-maintaining, light activated switch is easy to wear and be subjected to very easily that spot such as dust greasy dirt is polluted, water proofing property requires high.
The utility model content
The purpose of this utility model just is to provide a kind of pressure sensitive wheel carpenters square, and it had both solved the problem of stopping and detecting, and is simple in structure again, be not subjected to the surrounding working environment restriction, solved photosensitive formula wheel carpenters square variety of issue in use fully.
The purpose of this utility model is achieved through the following technical solutions: the utility model by wheel carpenters square base, be provided in the wheel carpenters square base the even quick switch of a compact arranged row pressure, with the supporting control circuit of pressure sensitive switch, be provided in the protection offset plate that triggers the trigger mechanism of pressure sensitive switch on the pressure sensitive switch and be assemblied in wheel carpenters square base top and constitute.
Automotive wheels carpenters square described in the utility model is two structures that wheel carpenters square left-right symmetric is used when using.The trigger mechanism structure of described pressure sensitive switch is: be equipped with upper cover plate under the protection offset plate on wheel carpenters square base, be equipped with supporting plate under the upper cover plate, the corresponding pressure sensitive switch with supporting plate of upper cover plate position is provided with a rows of openings, pass corresponding each pressure sensitive switch of perforate and be provided with a row switch button, the top of switch key contacts the protection offset plate, and the part that each button is positioned between upper cover plate and supporting plate is provided with back-moving spring.Be equipped with waterproof pad and press strip at wheel carpenters square base with protection offset plate and upper cover plate junction.
The utility model its beneficial effect after having adopted technique scheme is: its pressure sensitive structure is arranged so that time waste has been avoided in the dispense with parking detection in testing process, has guaranteed that the smoothness of testing process is carried out, and has improved efficient; It is not subjected to environmental impact on every side such as light, dust greasy dirt in the use, and usability is strengthened greatly; Wheel such as waterproof pad, press strip carpenters square junction be arranged so that the utility model water proofing property is very reliable.
