Abstract
The utility model relates to a kind of outer sensor, it comprises shell (1), base (2), tamper pad (3) and stem of valve (4), described stem of valve (4) inserts tamper pad (3) and base (2) successively, and by hexagonal nut (5) locking, screw thread fit is adopted to connect between described shell (1) and base (2), the end face of described shell (1) and the outer edge surface of tamper pad (3) are symmetrically arranged with the draw-in groove (1.2) and (3.2) that cooperatively interact, the end face outside of described base (2) offers a circle jack (2.2), the end face that described tamper pad (3) is relative with base (2) is provided with the inserting column (3.1) of a circle and jack (2.2) interference fit.Adopt the interference fit of jack and inserting column to be connected between base of the present utility model with tamper pad, its manufacture craft is simple, and easy accessibility, stability is high, long service life.
Description
Technical field
The utility model relates to a kind of automotive tire pressure detection equipment, is specifically related to a kind of external sensor.Belong to the sensing device field of tyre inner pressure.
Background technology
Existing outer sensor, for the antenna of the signal of the tyre inner pressure of outside spatial emission characterization pressure sensor detecting, usually be jointly made up of metal pieces such as the metallic conductor, connecting element, pedestal and the tire tube valves that are electrically connected with control circuit, to save the inside installing space of sensor, thus reduce the overall dimensions of sensor.
The pedestal of current outer sensor generally adopts the mode of gears meshing to be connected with between connecting element, processed complex degree and accuracy requirement higher.Meanwhile, owing to adopting gears meshing mode to connect, in use because dismounting maintenance easily causes the engagement degree between gear to be deteriorated, insecure, trouble is installed, easily destroys tire tube valve thread.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides that a kind of structure is simple, easy to assemble, the outer sensor of stable performance, improves the service life of outer sensor.
The purpose of this utility model is achieved in that a kind of outer sensor, it comprises shell, base, tamper pad and stem of valve, described stem of valve inserts tamper pad and base successively, and locked by hexagonal nut, screw thread fit is adopted to connect between described shell and base, the end face of described shell and the outer edge surface of tamper pad are symmetrically arranged with the draw-in groove that cooperatively interacts and, the end face outside of described base offers a circle jack, the end face that described tamper pad is relative with base is provided with the inserting column of a circle and jack interference fit.
Compared with prior art, the beneficial effects of the utility model are:
External sensing transmitter is installed on the valve bolt of tire with two kinds of connection modes by the utility model, be connected firmly, and there is certain anti-theft feature, its manufacture craft is simple, easy accessibility, even if occur when reality uses rotating the connection that also can not affect between the two, stability is high, long service life.
