Embodiment Construction

[0014] Such as figure 1 As shown, when assembling, first rotate the nut one (2) at the root of the bolt on the base (1), fix the nut two (3) on the inner side of the bearing (4), and install the outer side of the bearing (4) on the telescopic rod ( 5), and then rotate the bolt on the base (1) into the second nut (3) until the first nut (2) and the second nut (3) are tight; when in use, adjust the length of the telescopic rod (5), The bottoms of the bases (1) at both ends can be pressed against the wall.

[0015] Such as figure 2 As shown, turn the nut 2 (3) to move away from the base (1). With the movement of the nut 2 (3), the distance between the bases (1) at both ends and the lateral pressure on the wall gradually increase. become larger until the nut two (3) can no longer move, and finally, move the nut one (2) to lock the position of the nut two (3), at this time, the lateral pressure of the base (1) on the wall reaches an adjustable maximum value.

Abstract

The invention relates to a punching-free telescopic rod. The punching-free telescopic rod is mainly composed of a base, a first nut, a second nut, a bearing and a telescopic rod assembly. During installation, the length of the telescopic rod is adjusted to a proper position, the bases at the two ends abut against the wall face, then the length of the telescopic rod continues to be adjusted so that the extrusion force of the bases on the wall face can be further enhanced, the second nut is rotated to move in the direction away from the bases till the second nut cannot move any more, and finally the first nut is moved to lock the position of the second nut. At the moment, the side pressure of the base abutting against the wall surface reaches the adjustable maximum value. The invention has the advantages of high lateral extrusion force and low possibility of falling off.

Description

technical field [0001] The invention relates to a punching-free telescopic rod. Background technique [0002] Punch-free telescopic rods are daily necessities in people’s lives. They can be used for fitness, drying clothes, hanging curtains and shower curtains, etc. Currently, the punch-free telescopic rods on the market generally have low lateral extrusion force, Problems such as falling off easily bring many inconveniences to people's lives. Contents of the invention [0003] This invention mainly solves the problems of low lateral extrusion force and easy falling off of the currently available telescopic rod without punching in the market. [0004] For the above problems, the technical solution of the present invention is: the invention mainly consists of a base (1), a nut one (2), a nut two (3), a bearing (4) and a telescopic rod (5). [0005] The main features of the main parts profile and structural design of the present invention are as follows: [0006] A bolt i...
