Description

Technical Field

[0001] The utility model relates to the technical field of labor protection shoes detection, in particular to a device for detecting the insulation performance of labor protection shoes. Background Technique

[0002] Labor protection shoes are shoes that provide safety protection for the feet. The selection of labor protection shoes should be based on the nature and degree of harm in the working environment. Labor protection shoes should have a product certificate and a product manual. Before use, read the manual according to the usage conditions, and the usage method should be correct. For special protective labor protection shoes, they should be inspected and kept clean after use and stored in a pollution-free and dry place. There are many types of them, such as toe protection, puncture resistance, insulation, acid and alkali resistance, etc.

[0003] The patent authorization announcement number CN 216387272 U discloses a device for detecting the insulation performance of labor protection shoes, including: a first box body, a partition board, two groups of support plates, an insulation detector, a first wire, a second wire and a conductive plate. Among them, the partition board is arranged in the first box body, dividing the first box body into a detection area and a cleaning area; the two groups of support plates are symmetrically arranged in the cleaning area, and there is a gap between the two groups of support plates, and the span of the gap is smaller than the length of the labor protection shoes; one end of the first wire is arranged below the support plate, and the other end is connected to the insulation detector; one end of the second wire is arranged on the conductive plate, and the other end is connected to the insulation detector; a cleaning part is arranged in the cleaning area for cleaning the labor protection shoes that have been detected. The utility model fixes the labor protection shoes by placing them on the support plate. Compared with the method of clamping from the side, the stability of the labor protection shoes fixation is improved, and at the same time, the labor protection shoes can be automatically cleaned by the cleaning part.

[0004] However, the above technical solution has the following deficiencies: Most labor protection shoes are usually made of different materials for the soles and uppers. Only a simple detection of the insulation performance of the soles is carried out, and the insulation performance of the uppers of the labor protection shoes cannot be detected. The detection result is relatively one-sided. If there is a leakage situation due to some parts not being detected, the consequences will be unimaginable, and there are relatively large potential safety hazards. Summary of the Utility Model
