Automatic screw assembly or screw-loosening bulb positioning structure at high positions

Abstract

This invention provides an automatic bulb positioning structure for high-altitude bulb replacement, mainly comprising a gripping part, a power source, a servo motor, a rotating component, a rotating base unit, and a shock-absorbing inner bushing. The gripping part contains a control panel and control keys to control the forward and reverse rotation of the servo motor, which in turn drives the rotating component and the rotating base unit to rotate, allowing the bulb to be automatically locked or removed. The rotating base unit includes a shock-absorbing inner bushing and a fixing unit to securely hold the bulb and absorb rotational vibrations to prevent damage. A telescopic unit can be added to adjust the operating length, and a torque protection mechanism is included to prevent over-tightening. This achieves a safe, convenient, and suitable solution for high-altitude bulb replacement.

Claims

1. A height-adjustable automatic screw assembly or screw-loosening bulb positioning structure, comprising: a gripping part having a housing space inside, a control board being disposed within the housing space, the control board having a plurality of control keys exposed on the outer surface of the gripping part and having at least one control terminal, and an annular retaining flange being provided at one end of the housing space; a power source having at least one power terminal and being electrically connected to the control terminal of the control board; a servo motor being disposed in the housing space, the servo motor having at least one electrical control coupling terminal and being electrically connected to the control board and the power source respectively, and the servo motor having a motor spindle; and an annular bearing having an outer edge and an inner edge, the outer edge being fixed to the inner wall of the housing space and limited by the annular retaining flange, and being disposed at the axial position of the front end of the servo motor; A rotating component, one end of which has a rotating shaft and is connected to the motor spindle, so that the rotating component is driven to rotate by the servo motor. The outer periphery of the rotating component is fixed to the inner edge of the bearing component, and the other end of the rotating component forms an annular stop surface, and an external gear is provided in the center of the end face; a fixed ring sleeve, which is a hollow component, one end of which has an annular stop portion that abuts against the stop surface of the rotating component, and an internal thread section is provided on its inner periphery; a rotating base unit, including a rotating base body, one end of which is an open end, and the other end is a rotating end. The outer periphery of the rotating end is provided with an external thread section that screws into the internal thread section of the fixed ring sleeve, and the end face of the rotating end is provided with an internal gear that meshes with the external gear of the rotating component; a shock-absorbing inner bushing, which is disposed inside the rotating base body, is bag-shaped, one end of which is an open sleeve and protrudes from the open end, and the other end is closed and fixed to the inner wall of the rotating base body; And a fixing unit is provided near the opening of the shock-absorbing inner bushing, including a fixing part and a connecting member. The connecting member can encircle the opening and is detachably connected to the connecting end of the fixing part to fix the light bulb.

2. The height-adjustable automatic screw assembly or screw-loosening bulb positioning structure as described in claim 1, wherein a telescopic unit is provided between the gripping part and the rotating unit, the telescopic unit includes a first sliding sleeve and a second sliding sleeve, forming a multi-segment telescopic structure, wherein the gripping part is provided with a guide protrusion, the first sliding sleeve is provided with a corresponding first guide groove for guiding sliding and limiting, the second sliding sleeve is provided with a second guide groove that cooperates with the guide block inside the first sliding sleeve to form a segmented telescopic and positioning effect, and the second sliding sleeve is provided with an annular retaining flange inside to limit the bearing component.

3. The height-adjustable automatic screw assembly or screw-loosening bulb positioning structure as described in claim 1, wherein the power source is a removable storage battery, disposed at the end of the holding part's chamber space, the end of the holding part having a rear end with internal threads, and a rear cover screwed on to close and fix the power source.

4. The height-adjustable automatic screw assembly or screw-loosening bulb positioning structure as described in claim 1, wherein the control key includes a first control key and a second control key, which are used to control the forward and reverse rotation of the servo motor, respectively.

5. The height-adjustable automatic screw assembly or screw-loosening bulb positioning structure as described in claim 4, wherein the servo motor is equipped with a torque protection switch that automatically cuts off power when the output torque reaches a predetermined value to avoid bulb damage or over-tightening.

6. The height-adjustable automatic screw assembly or screw-loose bulb positioning structure as described in claim 1, wherein the fixing part is provided on the surface of the shock-absorbing inner bushing by means of stitching or bonding, and the connecting member is a strap structure of male and female hook and loop fasteners that can be repeatedly attached.

7. The height-adjustable automatic screw assembly or screw-loosening bulb positioning structure as described in claim 1, wherein the shock-absorbing inner sleeve is made of glass fiber material coated with epoxy resin to provide heat resistance and shock absorption.
