Description

Technical Field

[0001] The utility model relates to the technical field of springs, in particular to an anti-breakage spring. Background Art

[0002] In the field of mechanics and engineering, springs are a common elastic element widely used in various equipment and systems to provide support, cushioning, energy storage and other functions. However, with the development of modern industry, the performance requirements for springs are getting higher and higher. Especially under conditions of high load, high frequency, and complex environment, the problem of spring breakage has become increasingly prominent and has become an important factor restricting the stability and safety of equipment.

[0003] At present, there are many types of springs on the market, the most common of which is the coil spring. During long-term use, coil springs often break due to material fatigue, stress concentration, environmental corrosion and other reasons, resulting in equipment failure or even safety accidents. Therefore, anti-break springs are proposed. After searching, a Chinese utility model patent with patent number "CN 204900631U" discloses an anti-break spring, which has an anti-break effect by embedding the entire spring inside the elastic rubber. However, it was found during use that this type of spring is only suitable for extrusion and compression working environments, and cannot be used in stretching working environments, and is inconvenient to connect.

[0004] Therefore, an anti-break spring is needed to improve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-break spring to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An anti-break spring comprises a spring, wherein an elastic rubber component is arranged through the interior of the spring, and end rings are connected to both ends of the spring, and the end rings at both ends extend to the interior of both ends of the elastic rubber component to form an integral body, the spring and the elastic rubber component body are arranged separately, and a reinforcing piece is also arranged on the spring body.

[0008] As a preferred solution of the utility model, the elastic rubber component includes a rubber tube arranged inside the elastic rubber component, and rubber rings are arranged at both ends of the rubber tube, and the rubber rings are sleeved on the outside of the end rings.

[0009] As a preferred solution of the utility model, a plurality of folding parts are provided on the rubber tube.

[0010] As a preferred solution of the utility model, the reinforcement member is a reinforcement convex strip arranged on the outside of the spring.

[0011] As a preferred solution of the present invention, the cross-section of the reinforcing ridge is trapezoidal.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model arranges a rubber tube inside the spring, and rubber rings at both ends of the rubber tube are arranged on the outside of the end rings at the ends of the spring. When in use, the rubber tube can be used to avoid the spring from breaking. At the same time, the spring itself is provided with reinforcing convex strips to increase its strength. The utility model is suitable for a variety of working environments and has a wider range of applications than the comparative cases. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively below with reference to the relevant. Several embodiments of the utility model are given. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
