The outer wall of the lubricant tank body is fixedly connected with a fixing plate. Both the inner and outer walls of the fixing plate are annular. A sleeve is slidably connected to the outer wall of the fixing plate. The upper end face of the sleeve is in an open state. The inner wall of the sleeve fits with the outer wall of the fixing plate. The edge of the upper end face of the fixing plate is smoothly transitioned. A sealing gasket is fixedly connected to the inner wall of the sleeve. The lower end face of the sealing gasket has a certain arc and fits with the edge of the upper end face of the fixing plate.

[0007] Preferably, a plurality of groups of sliding grooves are formed in the outer wall of the fixing plate. The plurality of groups of sliding grooves are annularly distributed, and a sliding rod is fixedly connected to the inner bottom of each of them.

[0008] Preferably, a slider is slidably connected to the outer wall of the sliding rod, and the end of the slider is fixedly connected to the inner wall of the sleeve.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Refer to Figures 1-3, a maintenance tool for the battery pack cooling system, including a lubricant tank body 1. A thimble 2 is installed at the upper end of the lubricant tank body 1 and is communicated with the inside of the lubricant tank body 1. A fixing plate 5 is fixedly connected to the outer wall of the lubricant tank body 1. Both the inner and outer walls of the fixing plate 5 are annular. A sleeve 3 is slidably connected to the outer wall of the fixing plate 5. The upper end surface of the sleeve 3 is open. The inner wall of the sleeve 3 fits with the outer wall of the fixing plate 5. The edge of the upper end surface of the fixing plate 5 has a smooth transition. A sealing gasket 6 is fixedly connected to the inner wall of the sleeve 3. The lower end surface of the sealing gasket 6 has a certain curvature and fits with the edge of the upper end surface of the fixing plate 5;

[0021] During specific use, by pushing the thimble 2 upward, the lubricant in the lubricant tank body 1 can be ejected to a specified area. During this process, the provided sleeve 3 contacts the outer wall of the specified area in advance. During the continuous upward sliding of the thimble 2, the provided sealing gasket 6 continuously reduces the distance from the upper end surface of the fixing plate 5 until it contacts, forming a sealed space inside the sleeve 3 to prevent the operator from inhaling harmful gases.

[0022] A plurality of groups of chutes 7 are opened on the outer wall of the fixing plate 5. The plurality of groups of chutes 7 are annularly distributed, and a slide bar 8 is fixedly connected to the inner bottom of each of them. A slider 9 is slidably connected to the outer wall of the slide bar 8. The end of the slider 9 is fixedly connected to the inner wall of the sleeve 3. A spring 10 is sleeved on the outer wall of the slide bar 8. One end of the spring 10 is fixedly connected to the inner bottom of the chute 7, and the other end of the spring 10 is fixedly connected to the lower end surface of the slider 9;

[0023] The spring 10 provides an automatic reset function. When the thimble 2 is not in use, the sleeve 3 can automatically return to the specified position. At the same time, the elastic force of the spring 10 ensures that the sealing gasket 6 closely contacts the upper end surface of the fixing plate 5, enhancing the sealing effect.

[0024] The inner side wall of the chute 7 is arranged in a plane. One side outer wall of the slider 9 is in close contact with the inner side wall of the chute 7. A lamp tube 4 is installed on the upper end surface of the lubricant tank body 1. The outer wall of the lamp tube 4 is annularly arranged. A scale line 11 is provided on the side wall of the lubricant tank body 1;

[0025] The annular lamp tube 4 provides good lighting for the operation area, facilitating precise operation under low light conditions and reducing the risk of misoperation. The scale line 11 helps the operator accurately control the dosage of the lubricant, avoiding increased volatilization and harmful gas release caused by excessive use.

[0026] In the present utility model, when the device is in specific use: Ensure that the operating environment is well-ventilated to reduce the accumulation of harmful gases. Turn on the lamp tube 4 to ensure sufficient lighting in the working area for convenient and precise operation. Bring the maintenance tool to the designated area that needs lubrication of the battery pack cooling system, make the upper end face of the sleeve 3 contact the outer wall of the designated area in advance, and start the lubricant spraying mechanism by pushing up the ejector pin 2, so that the lubricant in the lubricant tank 1 is sprayed out to the designated area. During the continuous upward sliding of the ejector pin 2, the sealing gasket 6 continuously reduces the distance from the upper end face of the fixing plate 5 until it contacts, ensuring that a closed space is formed inside the sleeve 3. Spraying the lubricant in the closed space can prevent the operator from inhaling harmful gases.

[0027] When the lubrication operation is completed, release the ejector pin 2, and use the elastic force of the spring 10 to automatically return the sleeve 3 to the designated position. The spring 10 can ensure that the sealing gasket 6 is in close contact with the upper end face of the fixing plate 5, maintaining a good sealing effect to prevent the volatilization of residual lubricant. And through the scale line 11 on the side wall of the lubricant tank 1, accurately control the amount of lubricant used to ensure the use of an appropriate amount of lubricant and avoid the increased volatilization and release of harmful gases caused by excessive use.

[0028] Through the above work process, using this maintenance tool can effectively reduce the volatilization of lubricant and the release of harmful gases, ensure the safety of the operator, and improve the maintenance effect of the battery pack cooling system.

[0029] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
