Support group capable of achieving stepless adjustment

Abstract

The invention relates to a support group capable of achieving stepless adjustment. The support group comprises a first support body and a second support body which can slide relatively. The first support body is provided with a control assembly for manual operation of a user. The control assembly is provided with a first part moving along a reciprocating track relative to the first support body, a second part moving along an advancing and retreating track relative to the first support body, and an elastic part located between the first part and the second part. When the first part is located at one end of the reciprocating track, the elastic part completely stretches, and the second part does not abut against the second support body. When the first part is located at the specific position of the reciprocating track, the second part abuts against the second support body, and the elastic part is compressed to be shortest. When the first part is located at the other end of the reciprocating track, the second part still abuts against the second support body, and the elastic part does not completely stretch. The support group is easy and convenient to operate, the movable support bodies can be relatively positioned at any positions within the adjustable range, and the situation that the movable support bodies rapidly fall by accident during unlocking can be avoided.

Description

technical field [0001] The invention relates to a bracket body, in particular to a bracket group that can be adjusted steplessly. Background technique [0002] In daily life and in various fields, frame structures that can be manually adjusted by people are often used. Taking indoor sports equipment as an example, the seat bracket group in an upright exercise bike or weight training equipment can usually be used For the user to adjust the height position of the seat, and the seat bracket group in the recumbent exercise bike can be used for the user to adjust the front and rear positions of the seat. According to the positions that can be selected for positioning, the position adjustment of the above-mentioned bracket sets can be roughly divided into two categories: "adjustment with steps" and "adjustment without steps". The movable frame body is positioned in one of the preset multiple positions, such as the common structure where the pin is inserted into the positioning ho...

According to the positions that can be selected for positioning, the position adjustment of the above-mentioned bracket sets can be roughly divided into two categories: "adjustment with steps" and "adjustment without steps". The movable frame body is positioned in one of the preset multiple positions, such as the common structure where the pin is inserted into the positioning hole, which has disadvantages such as limited position selection, troublesome locking and unlocking operations, and clearance after positioning; On the contrary, the bracket group with stepless adjustment allows the user to posit
