Embodiment Construction

[0020] to combine Figure 1 to Figure 4 The multi-angle adjusting ratchet structure of the present invention is further described.

[0021] A multi-angle adjustable ratchet structure, which is characterized by: comprising a disc 1 and a ratchet 2 rotatably connected to the disc 1, the ratchet 2 is connected to the disc 1 in a rotatable structure through a rivet 3, and the rivet 3 is sleeved with The torsion spring, the two ends of the torsion spring are respectively positioned and inserted on the disc 1 and the ratchet 2, so as to provide a rotational torque for the ratchet 2. Described ratchet 2 is on rotation scope, has such as with respect to turntable figure 2 The left turn limit shown and the Figure 4 The right turn limit shown. The peripheral surface of the ratchet 2 has a ratchet groove 23 and a first limiting portion 21 and a second limiting portion 22 protruding from the peripheral surface of the ratchet 2. In this embodiment, the first limiting portion 21 and th...

Abstract

The invention discloses a multi-angle adjusting ratchet wheel structure, which comprises a disc and a ratchet wheel rotationally connected to the disc, and the ratchet wheel is provided with a left turning limit position and a right turning limit position relative to a rotary disc; a ratchet wheel groove, a first limiting part and a second limiting part are arranged on the circumferential surface of the ratchet wheel, and a first limiting rod and a second limiting rod are arranged on the disc; a first tension spring for pulling the first end of the first limiting rod to be clamped into the ratchet wheel groove is arranged between the disc and the first limiting rod; a second tension spring for pulling the first end of the second limiting rod to be away from the ratchet wheel is arranged between the disc and the second limiting rod; when the ratchet wheel rotates to a left-turning limit position, the first limiting part pushes the first end of the first limiting rod to be away from the ratchet wheel and abut against the first end of the second limiting rod; and when the ratchet wheel rotates to the right turning limit position, the second limiting part drives the first end of the second limiting rod to turn to the ratchet wheel so as to drive the first end of the first limiting rod to be clamped into the ratchet wheel groove. According to the invention, multi-angle adjustment can be realized, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of furniture accessories, in particular to a multi-angle adjusting ratchet structure. Background technique [0002] As a connecting part, the ratchet hinge is used to connect two unconnected materials together and enable the two materials to rotate relatively within a certain angle. Due to this characteristic of the hinge, it is widely used in various furniture , such as the backrest and headrest structure of the sofa. [0003] In the prior art, the structure of the ratchet hinge used in furniture is relatively simple, which causes a lot of inconvenience when it is installed in a sofa, so there is room for improvement. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a multi-angle adjustment ratchet structure, which can realize various angle adjustments and is easy to use. [0005] To achieve the above object, the present invention provides th...
