Problems solved by technology

At this time, the spring without the restraint of the fixed ring will bounce off, and if it is some strong spring with high torque, it will cause workers to be injured.
Even if no personal injury is caused, reassembly is required, affecting production efficiency
Furthermore, when the spring needs to be replaced during repair or maintenance, measures should also be taken to prevent the spring from bouncing and hurting people when the spring is taken out, which is also very inconvenient.

Embodiment Construction

[0021] The invention is a plane scroll spring.

[0022] Figure 1 to Figure 3 Shown is an embodiment of the planar scroll spring, which includes a spring body 1 . A fixed ring 3 is provided outside the outermost ring 2 of the spring body 1 to limit the spring body 1 from bouncing off. The fixed ring 3 can be a steel band ring as shown in the figure, or a wire ring (not shown in the figure). The end of the outermost ring 2 has an outer hook 4 exposed outside the fixed ring 3 . The outer hook 4 can be spliced ​​at the end of the spring body 1 or integrally formed with the end of the spring body 1 . Preferably, the width of the fixing ring 3 is smaller than the width of the spring body 1 .

[0023] In this embodiment, the fixed ring 3 is located at the middle position of the outermost ring 2 along the axial direction, and the outer hook 4 is divided into two parts, which are respectively located on both sides of the fixed ring 3 along the axial direction. As an alternative, ...

Abstract

The invention relates to a plane scroll spring. The plane scroll spring comprises a spring body, wherein the tail end of the outmost ring of the spring body has an outer hook; the outside of the outmost ring is provided with a fixed ring; and the outer hook is exposed out of the fixed ring. Because the outer hook is exposed, the plane scroll spring can be installed directly during assembly and does not need to remove the fixed ring before installation like the prior plane scroll spring; therefore, the plane scroll spring is quite convenient, and an outer ring of the spring does not pop out to cause personal injury; moreover, the plane scroll spring also has convenient maintenance and replacement.

Description

technical field [0001] The invention relates to a spring, in particular to a planar scroll spring. Background technique [0002] Flat scroll spring, also known as clockwork spring, is made of steel strip, one end of which is fixed, and the other end acts on torque, and the material produces bending elastic deformation. When the force disappears, the elastic force accumulated in the spring is released to return to its original state. [0003] After the existing planar scroll spring is manufactured, before it is assembled into the applied equipment or mechanism, it is necessary to put a retaining ring on the outermost surface of the spring to prevent it from bouncing off. When assembling, the retaining ring must be removed, and then the spring itself is assembled into the corresponding equipment or mechanism. During specific operation, the spring is pushed into the cavity accommodating the spring along the direction of its central axis, and the fixed ring is blocked by the o...
