Abstract
The utility model discloses a kind of contactless position detecting devices of screw, including screw, push away platform, sensor and magnet steel, the screw is arranged in the circular hole pushed away among platform, and the sensor is set to the screw side, and the magnet steel is set to described push away above platform.The utility model is using sensor and pushes away platform physical contact, structure without abrasion, it is simple in structure, it is small, installation is easy, later maintenance maintenance is simple, and adjustment corresponding actions position is adjusted by software algorithm, without changing installation site, to there is the special application field of the requirements such as anti-water segregation, can circuit board effectively be pushed away into platform component with screw and be isolated.
Description
Technical field
The utility model is related to a kind of detection device more particularly to a kind of contactless position detecting devices of screw.
Background technology
In screw rod transmission application field, it usually needs the feedback of one-point or multi-point position signal, existing feedback scheme are usual
Using travel switch or similar mechanical touch-switch, relative complex there are structure, volume is larger, and switch life is short, installation
It is not easy and changes the problems such as difficult once position after installing.
Utility model content
The technical problems to be solved in the utility model be in order to overcome the defects of the prior art, now provide a kind of screw without
Touch position detecting device.
The utility model is to solve above-mentioned technical problem by following technical proposals：
A kind of contactless position detecting device of screw of the utility model, feature are that the contactless position of screw is examined
It surveys device to include screw, push away platform, sensor and magnet steel, the screw is arranged in the circular hole pushed away among platform, the sensor
The screw side is set to, the magnet steel is set to described push away above platform.
Preferably, the magnet steel is opposite with the sensor homonymy.
Preferably, the screw is to be threadedly coupled with the platform that pushes away.
Preferably, the magnet steel is connected with the platform that pushes away by glue bonding.
Preferably, the sensor is Hall sensor
The positive effect of the utility model is：
The utility model is using sensor and pushes away platform physical contact, structure without abrasion, simple in structure, small, peace
Dressing is easy, and later maintenance maintenance is simple, and adjustment corresponding actions position is adjusted by software algorithm, right without changing installation site
There is the special application field of the requirements such as anti-water segregation, can circuit board effectively be pushed away into platform component with screw and be isolated.
Description of the drawings
Fig. 1 is the structure diagram of the position detecting device of the preferred embodiment of the utility model.
The schematic top plan view of Fig. 2 Fig. 1.
Specific embodiment
The utility model is further illustrated below by the mode of embodiment, but be not therefore limited in the utility model
Among the embodiment described range.
Fig. 1~2 please be participate in, a kind of contactless position detecting device of screw of the utility model including screw 1, pushes away platform 2, biography
Sensor 3 and magnet steel 4, screw 1 pass through the circular hole pushed away among platform 2, and pushing away platform 2 can move up and down along screw 1, and sensor 3 is installed
It being fixed on casing or stent in 1 side of screw, magnet steel 4 is mounted on and pushes away above platform 2, is not contacted between magnet steel 4 and sensor 3,
It during work, is moved up and down as the rotation drive of screw 1 pushes away platform 2, sensor 3 is generated by perceiving the strong and weak variation in 4 magnetic field of magnet steel
Corresponding signal redirects, and 2 corresponding position of platform is pushed away so as to obtain.
Preferably, magnet steel 4 is opposite with 3 homonymy of sensor, and convenient for the sensing of sensor 3, screw 1 connects with pushing away platform 2 for screw thread
It connects, magnet steel 4 is connected with before pushing away platform 2 by glue bonding, and sensor is Hall sensor.
The utility model is described in detail above in association with attached drawing embodiment, those skilled in the art can root
Many variations example is made to the utility model according to above description.Within the spirit and principle of the utility model, that is made appoints
What modification, equivalent replacement, improvement etc., should be included within the scope of protection of this utility model.Thus, it is certain in embodiment
Details should not form the restriction to the utility model, and the utility model will be using the range that the appended claims define as this reality
With novel protection domain.
