Description

Torsion structure

The present invention relates to a torsion structure, especially in a torsion structure, after the fixing member is assembled, the first retaining ring is assembled on the first ring groove, and the fixing member can be restricted by the first retaining ring Without coming out, the second body, the fixing base and the plurality of fixing pieces are more easily assembled in the accommodating groove.

According to our previous knowledge, the conventional torsion structure, such as Taiwan patent case number: 108141779, certificate number: I702118, patent name: torsion structure, the patent case structure is: a torsion structure, which includes: a first body 10 , the first body 10 is internally provided with an accommodating slot 11; a second body 20 is pivoted with the first body 10, and one end of the second body 20 is provided with a driving part 21, The second body 20 is provided with a plurality of first fixing portions 23 , the first fixing portions 23 are hidden in the accommodating groove 11 , and the second body 20 is provided with a plurality of first pivot portions 24 . The part 24 is hidden in the accommodating groove 11; a first elastic piece 25 is accommodated and springs against the second body 20, so that the second body 20 has a torsional escape Efficacy; a fixed seat group 40, the fixed seat group 40 is fastened in the second body 20, the fixed seat group 40 includes a fixed seat 41, a plurality of fixed parts 42 and a plurality of pivoting parts 43; the fixed seat 41 is fixed in the second body 20, the fixing seat 41 is provided with a plurality of second fixing parts 412, each second fixing part 412 is opposite to each first fixing part 23, the fixing seat 41 is A plurality of second pivot portions 413 are provided, and each second pivot portion 413 is opposite to each first pivot portion 24 ; the fixing member 42 is assembled on the At the first fixing portion 23 and the second fixing portion 412, the fixing base 41 is fixed in the second body 20 and cannot be disengaged from each other; the pivoting member 43 is pivoted on the first pivoting portion 24 and the second pivot portion 413, the pivot member 43 is loosely fitted with the first pivot portion 24 and the second pivot portion 413, that is, the pivot member 43 can be connected to the first pivot portion 24 and the second pivot portion 413 roll naturally, the pivot member 43 is slightly protruding from the second body 20 and abuts on the inner peripheral surface of the accommodating slot 11, when the first body 10 is opposite to the When the second body 20 is rotated and displaced, the pivoting member 43 and the first body 10 have the effect of rolling friction.

But the lack of this conventional torsion structure is:

During assembly, the fixing base 41 is firstly inserted into the second body 20, and the plurality of fixing parts 42 are then accommodated on each first fixing part 23 and each second fixing part 412, but the plurality of fixing parts 42 It is arranged in a ring shape, and the second hand needs to press the two fixing pieces 42 at the same time, so that the second body 20, the fixing seat 41 and the plurality of fixing pieces 42 can be easily pivoted with the accommodating groove 11. It is more troublesome to use second hand together.

In view of the above-mentioned shortcomings of the conventional structure, the inventor of the present invention has finally developed a product with a torsion structure that can solve the drawbacks of the conventional structure with years of experience in manufacturing, production and design in related industries.

The problem to be solved by the invention: when the conventional torsion structure is assembled, the second hand needs to press the two fixing pieces at the same time, so that the second body, the fixing seat and the plurality of fixing pieces are easy to be pivoted with the accommodating groove, and assembled It is more troublesome to use second hand together. In the torsion structure of the present invention, after the fixing member is assembled, the first retaining ring is assembled on the first ring groove, and the fixing member can receive the first retaining ring. Restricted and not detached, the second body, the fixing base and the plurality of fixing pieces are more easily assembled in the accommodating groove.

Technical means for solving the problem: The present invention relates to a torsion structure, which includes: a first main body part is provided with an accommodating slot; a second main body part is provided with a pivoting part, a plurality of first fixing parts, a first an annular groove, a second annular groove and a first pivot portion; the first annular groove is in communication with the plurality of first fixing portions; the second annular groove is arranged between the driving portion and the first annular groove ; A fixed base set includes a fixed base and a plurality of fixed parts; the fixed base is provided with a first pivoting part passing through, and one end of the fixed base is provided with a first accommodating part and a plurality of second fixed parts; the fixed part The parts are assembled at the first fixing part and the second fixing part; a first buckle is assembled at the first ring groove, and the first buckle is pressed against the plurality of fixing parts; a The second buckle is fastened on the second ring groove.

Compared with the effect of the prior art: after the fixing member is assembled, the first retaining ring is assembled on the first ring groove, and the fixing member can be restricted by the first retaining ring and will not come out of the first fixing portion and Outside the second fixing portion, the second body, the fixing base and the plurality of fixing pieces are more easily assembled in the accommodating groove. The tolerance between the first retaining ring and the accommodating groove and the second body is smaller than the tolerance between the second body and the accommodating groove, between the second retaining ring and the accommodating groove and the second The tolerance of the body is also smaller than the tolerance between the second body and the accommodating groove, and the first retaining ring and the second retaining ring can slightly eliminate the gap between the accommodating groove and the second body. The first clasp and the second clasp have two places to eliminate the gap and have an interval, and the first clasp and the second clasp are arranged between the first body and the second body, so that the There is a better pivoting structure between the first body and the second body.

In order to make the committee members and those who are familiar with the art fully understand the effect of the present invention It is understood that the structure and composition of the present invention are described below with reference to the drawings and drawing numbers, but the following descriptions are only used to explain the embodiments of the present invention, and are not intended to limit the present invention in any form.
