Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely explained below with reference to the drawings in the embodiments of the present invention.

Referring to fig. 1-7 to illustrate the embodiment, a fin angle limiting device includes a housing 5, a rotary potentiometer 6, a limiting mechanism and a fin stabilizer control mechanism, the limiting mechanism includes two sensing plates 1 and two adjusting assemblies, the sensing plate 1 is a T-shaped structure, the sensing plate 1 is fixedly connected with an output shaft at the lower end of the rotary potentiometer 6, the two adjusting assemblies are symmetrically arranged along a horizontal central line of the bottom surface of the housing 5, each adjusting assembly includes a sensor mounting plate 2, a proximity switch 3 and an adjusting screw 4, the sensor mounting plate 2 is mounted on the bottom surface of the housing 5, the sensor mounting plate 2 is provided with a threaded through hole, the adjusting screw 4 penetrates through the side wall of the housing 5 and is screwed with the threaded through hole of the sensor mounting plate 2, the upper surface of the sensor mounting plate 2 is fixedly connected with the proximity switch 3, the proximity switch 3 in each adjusting assembly is in signal connection with the fin stabilizer control mechanism.

In this embodiment, when the output shaft at the lower end of the rotary potentiometer 6 rotates, the sensing plate 1 fixedly connected with the output shaft is driven to rotate synchronously, when the rotation angle reaches the required limit angle, the head of the T-shaped structure of the induction plate 1 enters the detection range of the proximity switch 3, the proximity switch 3 detects and outputs a fin angle limit signal to the fin stabilizer control mechanism, the fin angle is controlled within a limited amplitude range through the fin stabilizer control mechanism, the detection range of the proximity switch 3 covers the maximum motion range of the induction plate 1, so that the limit angle of the maximum fin angle is greatly increased, the relative position of the sensor mounting plate 2 can be changed by adjusting the adjusting screw 4, so that the sensor mounting plate 2 slides along the axial direction of the threaded through hole, therefore, the relative position of the proximity switch 3 fixedly connected with the upper surface of the sensor mounting plate 2 is changed, and the maximum limit fin angle can be continuously adjusted and set without opening the shell 5.

This embodiment 2 screw thread through-hole both ends of sensor mounting panel are equallyd divide do not with adjusting screw 4 spiro union, and screw thread through-hole both ends are equallyd divide do not set up adjusting screw 4 and conveniently carry out quick adjustment to proximity switch 3's relative position. A plurality of mounting hole has been seted up to sensor mounting panel 2 upper surface, proximity switch 3 passes through mounting hole and sensor mounting panel 2 fixed connection, as shown in fig. 4, in this embodiment mounting hole quantity is 6, and proximity switch 3 utilizes two pieces of screws and mounting hole cooperation to fix at sensor mounting panel 2 upper surface, through linking to each other proximity switch 3 with the mounting hole of difference, can make the control range at spacing fin angle further expand. The adjusting range of the limiting fin angle can be further changed by adjusting the distance between the two ends of the T-shaped head of the induction plate 1. Proximity switch 3 is general part in this device, and adjusting screw 4 is the standard component, and the market is all purchasable, and tablet 1 and sensor mounting panel 2 are machined parts.
