Problems solved by technology

[0002] In detection, detection tooling, photography, and stage performances, in order to facilitate the shooting and detection of photographic instruments and detection instruments, the assistance of telescopic brackets is often needed. Generally, the traditional telescopic brackets are triangular brackets to support three-section antenna rods, and steel wire ropes are used. The pulley block lifting mechanism, or the single-section screw jacking structure, this traditional telescopic support structure will be restricted by the use environment, the scope of application is not wide, and it cannot be smoothly photographed or detected in individual small spaces, and cannot meet the requirements of the work. need
[0003] At the same time, for the telescopic mechanism of the telescopic bracket, the similar telescopic mechanisms currently on the market can only stretch one section; The protruding length is too short to about 2 meters, and it cannot fully meet the needs of customers in some small spaces and during transportation.

Abstract

The invention discloses a double-screw device with hollow screw rods. The double-screw device is small in retracting size and long in stretching distance and includes a lower cylinder body located at the lowermost portion. A guide rod and a multi-head lead screw are installed in the lower cylinder body. A ball lead screw is arranged at the upper portion of the multi-head lead screw. The upper portion of the guide rod is arranged in the ball lead screw. The guide rod slides vertically in the multi-head lead screw and the ball lead screw. The ball lead screw moves vertically in the multi-head lead screw. By means of the double-screw device with the hollow screw rods, the structure with the positive screw rod and the negative screw rod is adopted, according to the two screw rods, the lead screws are used in a nested manner, occupied space is reduced when the two lead screws are in a retracted state, the structure is reasonable, operation is convenient, and the use range is wide.

Description

technical field [0001] The invention relates to the field of telescopic brackets, in particular to a hollow helical rod double helix device. Background technique [0002] In detection, detection tooling, photography, and stage performances, in order to facilitate the shooting and detection of photographic instruments and detection instruments, the assistance of telescopic brackets is often needed. Generally, the traditional telescopic brackets are triangular brackets to support three-section antenna rods, and steel wire ropes are used. The pulley block lifting mechanism, or the single-section screw jacking structure, this traditional telescopic support structure will be restricted by the use environment, the scope of application is not wide, and it cannot be smoothly photographed or detected in individual small spaces, and cannot meet the requirements of the work. need. [0003] At the same time, for the telescopic mechanism of the telescopic bracket, the similar telescopic...
