Embodiment Construction

[0016] The specific implementation manner of the present invention will be described in more detail below with reference to schematic diagrams. The advantages and features of the present invention will be more apparent from the following description. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0017] As mentioned in the background art, usually the eccentric spring needs to be pre-tightened in order to provide the initial holding force of the mechanical structure during the installation process of the mechanism. In this process, the spring may be wrongly installed in the design position, and it is difficult to recognize the time difference in the actual implementation.

[0018] Therefore, in the technical field of mechanical structure design, in order to solve the above problems, the present invention pr...

Abstract

The invention provides a mechanism for installing an error prevention eccentric spring. The mechanism for installing the error prevention eccentric spring comprises an eccentric spring, an eccentric wheel, a shell and a cover plate. A first spring leg inserting hole is formed in the eccentric wheel, and a first cone structure is arranged on the periphery of the first spring leg inserting hole in atightly attaching mode. A second spring leg inserting hole is formed in the shell, and a second cone structure is arranged on the periphery of the second spring leg inserting hole in a tightly attaching mode. According to the mechanism for installing the error prevention eccentric spring, the installation position and state of the eccentric spring are obviously different due to the fact that thefirst cone structure is arranged on the periphery of the first spring leg inserting hole in a tightly attaching mode, the second cone structure is arranged on the periphery of the second spring leg inserting hole in a tightly attaching mode, when spring legs of the eccentric spring does not correctly be inserted into the spring leg inserting holes, in the installation process of the cover plate, the spring legs of the eccentric spring may be pushed off the spring leg inserting holes by the cone structures, so that eccentric spring installation errors are easy to recognize, and the installationerrors can be corrected timely.

Description

technical field [0001] The invention relates to the technical field of mechanical structure design, in particular to an installation error-proof eccentric spring mechanism. Background technique [0002] Eccentric springs are widely used in mechanical design, and have the advantages of small size, reliable use, and no need for external energy to maintain their state. But usually the eccentric spring needs to be preloaded in order to provide the initial holding force of the mechanical structure during the installation process of the mechanism. In this process, the spring may be wrongly installed in the design position, and it is difficult to recognize the time difference in the actual implementation. Contents of the invention [0003] The purpose of the present invention is to provide an eccentric spring mechanism for preventing mistakes in installation, so as to solve the problem that existing eccentric springs are difficult to identify when they are installed incorrectly....
