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

[0023] The invention is a plane scroll spring.

[0024] 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 .

[0025] 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 flat spiral spring which comprises a spring body, wherein the tail end of the utmost outer ring of the spring body is provided with an outer hook; the outer side of the utmost outer ring is provided with a fixing ring; and the outer hook is exposed to the fixing ring. Because the outer hook is exposed, being different form the traditional flat spiral spring, the outer hook can be directly installed in assembling without dismounting the fixing ring, therefore, the spring is very convenient to install, the spring outer ring can not be popped up to cause personal injury; and the spring is very convenient to maintain and replace.

Description

[0001] Instructions for Divisional Application [0002] The present invention is a divisional application submitted on July 21, 2008, the application number is 200810040809.1, and the title of the invention is "planar scroll spring". technical field [0003] The invention relates to a spring, in particular to a planar scroll spring. Background technique [0004] 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. [0005] 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 sprin...
