Description

Cantilever structure

This creation belongs to the field of cantilever rotation technology, specifically refers to a cantilever structure that can rotate horizontally and freely at the joint, so as to improve the smoothness of the rotation, and it is convenient to adjust the tightness and enhance its practicability.

Pressing, the cantilever is mainly used to connect the objects at both ends, and in order to allow the two ends of the cantilever to rotate relative to each other, usually a rotating joint is provided in the middle of the cantilever, so that the two ends can rotate freely vertically, for example, for processing. The cantilever of the control box of the implement has one end fixed to the body, and the other end is used to lock the control box, so that when the user observes the processing progress or performs the fine adjustment setting, the control box can be rotated to the appropriate position. Angle, and when the setting is completed, the control box can be removed to avoid affecting the processing environment, and these actions are mainly performed through the aforementioned cantilever with a rotating joint; while the conventional cantilever is mainly composed of two L The curved pipe member is relatively pivotally connected, and is mainly provided with a bearing member between the joint ends of the two curved pipe members, so that the two curved pipe members can be relatively freely pivoted, but the conventional one is not only complicated in structure but also in use. For a period of time, it may change the smoothness of its rotation due to wear, and it is impossible to adjust the tightness of its rotation according to actual needs, which is not suitable for practical needs; in order to solve the aforementioned conventional cantilever rotation For the problem of joints, the applicant has developed an "adjustable rotary joint structure" of application No. 98221663, which can be solved. The traditional can not be adjusted and some of the smoothness of the trouble, but because of the design of the upper and lower clamping and screwing, the joints of the upper and lower cantilever may have different axes during the locking process, not only Affecting its stability, and there will be a situation of tilting to one side, causing the gasket to be unevenly pressed, causing unevenness in the rotation, which further affects the smoothness of the rotation, so assembly At the same time, the axis correction is required for the upper and lower joint members, the bushing member and the built-in lock seat, which causes inconvenience and trouble in assembly. In addition, when it is desired to adjust its tightness requirement, it needs to rotate the bushing member and the built-in lock seat, so that the entire rotating joint needs to be disassembled, so the adjustment is extremely inconvenient; in other words, the existing rotating joint of the cantilever is not perfected due to design, resulting in its existence. There are problems such as poor stability, difficulty in adjustment, uneven rotation due to uneven pressure, and difficulty in assembly. Therefore, how to improve the aforementioned problems is a current task.

In view of this, the creator has in-depth discussion on the problems faced by the existing cantilever, and has been actively seeking solutions through years of experience in R&D and manufacturing of related industries.
