Description

Technical Field

[0001] This utility model relates to the field of welding machine testing equipment, specifically a trolley used in welding machine testing equipment. Background Technology

[0002] Electric welding machines use the high-temperature electric arc generated when the positive and negative poles are short-circuited for a moment to melt the welding material on the welding rod and the material being welded, so that the objects in contact are joined together. However, long-term use of electric welding machines can easily lead to problems such as insulation aging and circuit damage. Regular inspection is required to detect potential hazards such as leakage and insufficient withstand voltage in a timely manner, so as to avoid equipment short circuits and fires or electric shocks to operators.

[0003] In the prior art, in order to facilitate the inspection of welding machines, the inspection equipment is usually placed on a cart for easy movement. However, in order to facilitate the use of the inspection equipment to inspect welding machines, the cart is generally unprotected. Over time, dust and other debris can easily come into contact with the placed inspection equipment and adhere to the surface of sensors and probes, which can hinder signal transmission or energy sensing. For example, after dust accumulates on current and voltage sensors, data drift and reading deviation may occur. Based on this, this utility model proposes a cart for welding machine inspection equipment. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-3 In this embodiment of the present invention, a trolley for testing an electric welding machine includes a movable trolley 1 and a protective shell 2 axially slidably mounted on the outside of the movable trolley 1. The protective shell 2 has a slot formed on its side for the movable trolley 1 to enter. A testing device 3 for testing the electric welding machine is placed on the top of the movable trolley 1. The device also includes a limiting mechanism 4 set on the protective shell 2 for limiting the movement of the protective shell 2. The limiting mechanism 4 includes a limiting unit and a reset unit; The limiting unit is used to provide a limit for the connection between the protective shell 2 and the movable trolley 1; The reset unit is used to provide a reset thrust for the limit unit after the activity has occurred; The limiting unit includes a push block 401, a movable rod 402, a push rod 403, a limiting block 404, and a guide groove 405; The movable rod 402 is axially slidably installed on the top of the protective shell 2. A push block 401 is fixed to one end of the movable rod 402 near the handle of the protective shell 2. The push block 401 is used to push the movable rod 402 to move axially. A push rod 403 is fixed to the inner side of the other end of the movable rod 402 to give the guide groove 405 a squeezing force. The limiting block 404 is vertically slidably installed on the top of the protective shell 2 and penetrates the protective shell 2 to the inner side of the protective shell 2. The guide groove 405 is inclinedly opened on the outer wall of the limiting block 404. The guide groove 405 is used to cooperate with the push rod 403 to drive the limiting block 404 to move vertically. The reset unit includes a positioning rod 406 and a spring 407; The positioning rod 406 is fixed to the side outer wall of the push block 401 and passes through the top protrusion of the protective shell 2.

The person pushing the trolley can directly apply the pushing force to the push block 401 near the handle by hand. Push block 401 will synchronously push positioning rod 406 to move axially along the outer wall of the protrusion at the top of movable trolley 1, and apply compressive force to spring 407, so that push block 401 pushes movable rod 402 and push rod 403 to move axially. The axially moving push rod 403 will apply compressive force to guide groove 405, so that the inclined guide groove 405 is driven by the compressive force from push rod 403 to move limiting block 404 upward, so that the bottom "U"-shaped groove of limiting block 404 moves out of the outer wall of side guard plate of movable trolley 1, thereby releasing the axial movement limitation between protective shell 2 and movable trolley 1. At this time, axial movement pulling force can be applied to protective shell 2, so that protective shell 2 moves axially along the top of movable trolley 1 to expose the detection equipment 3 placed on movable trolley 1, thus achieving the purpose of protecting detection equipment 3 when not in use and quickly removing detection equipment 3 when needed.
