Description

Technical Field

[0001] This utility model relates to the field of disc springs, and in particular to a disc spring with an overload protection device. Background Technology

[0002] Disc springs are a type of spring washer, typically employing a conical disc-shaped elastic structure. When compressed, they undergo elastic deformation and store a certain amount of potential energy. Disc springs can be used individually or in combination, offering high flexibility.

[0003] When two disc springs are used together, they undergo elastic deformation under pressure. Due to the lack of overload protection, if the pressure is too high, the disc springs are easily over-compressed, shortening their service life or even causing damage due to excessive deformation. This results in poor safety and requires improvement. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a disc spring with an overload protection device to protect against overload and improve safety during use.

[0005] To solve the above-mentioned technical problems, the present invention provides a disc spring with an overload protection device, comprising: an overload protection device, a first disc spring base, and a second disc spring base. The first disc spring base is disposed opposite to the second disc spring base above it. The overload protection device includes an elastic support body, a first limiting cone sleeve, and a second limiting cone sleeve. The first limiting cone sleeve is concentrically disposed inside the first disc spring base, and the second limiting cone sleeve is concentrically disposed inside the second disc spring base. The elastic support body is disposed between the first limiting cone sleeve and the second limiting cone sleeve.

[0006] In a preferred embodiment of the present invention, the bottom surface of the first limiting cone sleeve is provided with first positioning blind holes corresponding to the elastic support body at intervals, and the top surface of the second limiting cone sleeve is provided with second positioning blind holes corresponding to the elastic support body at intervals.

[0007] In a preferred embodiment of this utility model, the elastic support is a helical spring.

[0008] In a preferred embodiment of the present invention, the top of the first limiting cone sleeve is provided with a first cone surface corresponding to the inner wall of the first disc spring base.

[0009] In a preferred embodiment of the present invention, the bottom of the second limiting cone sleeve is provided with a second cone surface corresponding to the inner wall of the second disc spring base.

[0010] In a preferred embodiment of the present invention, the bottom of the first limiting cone sleeve is provided with a first annular plane, and the top of the second limiting cone sleeve is provided with a second annular plane corresponding to the first annular plane.

[0011] The beneficial effects of this utility model are as follows: The disc spring with overload protection device disclosed in this utility model, when the first disc spring base and the second disc spring base are deformed under force, drives the first and second limiting cone sleeves to reduce the distance between them. When the first and second limiting cone sleeves contact each other, further deformation of the first and second disc spring bases is prevented, thus achieving overload protection, avoiding damage to the first and second disc spring bases, and improving safety in use.

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] Please see Figures 1-2 The embodiments of this utility model include:

[0017] like Figure 1 The disc spring with overload protection device shown includes: an overload protection device, a first disc spring base 1 and a second disc spring base 2. The first disc spring base 1 is disposed above the second disc spring base 2, with the opening of the first disc spring base 1 pointing downward and the opening of the second disc spring base 2 pointing upward, and they are used in conjunction.

[0018] In this embodiment, the overload protection device includes an elastic support body 5, a first limiting cone sleeve 3, and a second limiting cone sleeve 4. The first limiting cone sleeve 3 is concentrically arranged inside the first disc spring base 1. The top of the first limiting cone sleeve 3 is provided with a first conical surface 8 corresponding to the inner wall of the first disc spring base 1, which facilitates assembly and improves concentricity.

[0019] The second limiting cone sleeve 4 is concentrically disposed inside the second disc spring base 2. The bottom of the second limiting cone sleeve 4 is provided with a second cone surface 9 corresponding to the inner wall of the second disc spring base 2, to ensure the concentricity of the second limiting cone sleeve 4 in the second disc spring base 2.

[0020] The elastic support 5 is positioned between the first limiting cone sleeve 3 and the second limiting cone sleeve 4, such as... Figure 1 As shown, the first limiting cone sleeve 3 and the second limiting cone sleeve 4 are elastically supported. In this embodiment, 2 to 4 elastic support bodies 5 are arranged in a circular array to ensure the stability of the first limiting cone sleeve 3 and the second limiting cone sleeve 4.

[0021] like Figure 2 As shown, the elastic support 5 is made of a helical spring. The bottom surface of the first limiting cone sleeve 3 is provided with first positioning blind holes 6 that correspond one-to-one with the elastic support 5. The top surface of the second limiting cone sleeve 4 is provided with second positioning blind holes 7 that correspond one-to-one with the elastic support 5. This is to position the two ends of the elastic support 5, improve the stability during use, and prevent it from flying off.

[0022] In this embodiment, the bottom of the first limiting cone sleeve 8 is provided with a first annular plane, and the top of the second limiting cone sleeve 4 is provided with a second annular plane corresponding to the first annular plane. When the first disc spring base 1 and the second disc spring base 2 are deformed by force, the first limiting cone sleeve 8 and the second limiting cone sleeve 4 are driven to reduce the distance between the first limiting cone sleeve 8 and the second limiting cone sleeve 4. When the first annular plane of the first limiting cone sleeve 8 and the second annular plane of the second limiting cone sleeve 4 come into contact, further deformation of the first disc spring base 1 and the second disc spring base 2 is prevented, overload protection is achieved, and damage to the first disc spring base 1 and the second disc spring base 2 is avoided.

[0023] In summary, the disc spring with overload protection device disclosed in this utility model can provide overload protection, which helps to extend its service life and improve its safety in use.
