Description

Technical Field

[0001] The utility model relates to the field of protective covers, and particularly relates to a structure of a telescopic steel plate protective cover. Background Art

[0002] In the industrial field, bellows covers are often used to protect the internal mechanical structure from foreign objects entering the machine. However, in the actual cutting field, telescopic protective covers are also applied, which can not only protect the internal structure but also remove debris.

[0003] At that time, the existing protective covers generally had a large span. After being bent or welded, due to material stress problems, deformation problems often occurred, such as concave or curved surfaces, which affected the fit between the sliding shells, resulting in fine chips entering between the shells and affecting the cleaning effect and use stability (such as noise or jamming problems). The existing method was generally to increase the thickness of the shell plate, thereby reducing the degree of deformation and improving the fit between the shells. However, this method had a high production cost. Summary of the Utility Model

[0004] The main purpose of the utility model is to propose a structure of a telescopic steel plate protective cover, aiming to improve the existing telescopic protective cover structure, reduce its degree of deformation while ensuring a small thickness of the shell, ensure the fit between the shells, and ensure the cleaning effect.

[0005] To achieve the above purpose, the utility model proposes a structure of a telescopic steel plate protective cover, including:

[0006] A base,

[0007] A plurality of shells, which are stacked and attached to each other. The shell includes a bottom shell, a middle shell slidably mounted on the upper wall of the bottom shell, and a top shell slidably mounted on the upper wall of the middle shell. At least one middle shell is provided. The bottom shell is slidably mounted on the upper wall of the base and is attached to it;

[0008] The upper wall surface of the shell is a cover surface, and at least one reinforcing strip is provided on the bottom wall of the shell along the length direction of the shell;

[0009] Guide chutes for the reinforcing strip to slide are provided on the upper wall of the base, the upper wall of the bottom shell, and the upper wall of the middle shell.

[0010] In the actual design, by providing a reinforcing strip on the bottom wall of the shell, the support degree of the shell is improved, the deformation after welding or processing is reduced. At the same time, without increasing the thickness of the shell, the fit between the shells or between the shell and the base is ensured. At the same time, through the cooperation of the reinforcing strip and the guide chute, the sliding stability of the shell can be further ensured, playing a guiding role.
