Embodiment

[0021] The embodiment of the present invention provides a stretch limit spring, see figure 1 , figure 2 The stretch limit spring includes a spring body 1, a spring base 2 extending from the spring body 1 to one side, a spring end body 3 extending from the spring body 1 to the other side, and a spring base 2 arranged at the end of the spring base 2. The limit strip 4 between the end of the spring end body 3.

[0022] Specifically, from the end of the spring base 2 to the direction of the spring body 1, the inner diameter gradually increases; from the end of the spring end body 3 to the direction of the spring body 1, the inner diameter gradually increases.

[0023] Specifically, the limit bar 4 is arranged between the end of the spring base 2 and the end of the spring end body 3, so that the spring cannot be stretched infinitely, so as to ensure that the spring body 1 will not be overstretched and cause the elastic force to disappear, and ensure that the spring can Stay stre...

Abstract

The invention discloses a stretching limiting spring, and belongs to the field of mechanical parts. The stretching limiting spring comprises a spring body, a spring base body arranged extending from the spring body to one side, a spring end body arranged extending from the spring body to the other side, and a limiting strip arranged between the end of the spring base body and the end of the springend body. The inner diameter is gradually increased from the end of the spring base body to the direction of the spring body, and the inner diameter is gradually increased from the end of the springend body to the direction of the spring body. The spring body, the spring base body and the spring end body are of an integrated structure. Anticorrosive layers are arranged on the surfaces of the spring body, the spring base body and the spring end body correspondingly. By arranging the limiting strip, the spring is prevented from being excessively stretched, the spring is protected while it is guaranteed that the spring has sufficient elasticity, the structure is simple, and using is convenient.

Description

technical field [0001] The invention relates to the field of mechanical parts, in particular to a tension limit spring. Background technique [0002] Spring is a very commonly used tool in people's daily life. The spring force can realize the reset of objects at both ends of the spring. [0003] The spring in the prior art includes a spring body, a spring base body extending from the spring body to one side, and a spring end body extending from the spring body to the other side. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0005] There is no limit measure for the spring. When the external force is too large, the spring will be overstretched, resulting in the spring having no elastic force and unable to reset. Contents of the invention [0006] In order to solve the problems in the prior art, an embodiment of the present invention provides a tension limit spring. Desc...
