Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery technology, and in particular to a lubrication tool for the vent hole of a battery. Background Technology

[0002] As user demands increase, more and more cars are placing their batteries in enclosed environments. When a battery is working, the water in the electrolyte decomposes, producing gases such as hydrogen and oxygen. Therefore, vent holes need to be installed on the battery cover to direct the gases generated during charging and discharging outside the vehicle. This requires inserting a vent pipe into the vent hole. However, due to the tight fit between the various battery components, assembling the vent pipe is difficult. Therefore, grease is usually added to the vent hole during battery manufacturing to facilitate the insertion of the vent pipe.

[0003] The current method of adding lubricant involves manually applying lubricant or grease to a cotton swab and then inserting the swab into the vent hole. However, because the diameter of the vent hole is relatively small, manual operation is not only time-consuming and laborious, but also prone to errors in accurately inserting the swab into the vent hole. This can result in the lubricant on the swab being smeared onto the battery cover, potentially causing a short circuit due to conductivity, especially in humid environments. In addition, some lubricants contain acidic or alkaline additives, and long-term residue may corrode the battery casing or seals, shortening the equipment's lifespan. Furthermore, cotton swab fibers may detach and clog the vent hole, affecting the battery's normal venting function, potentially leading to internal pressure buildup or even an explosion. Utility Model Content

[0004] The purpose of this invention is to provide a lubrication fixture for battery vent holes, which can save time and effort when adding grease to the vent holes, and can accurately apply the grease to the vent holes, thus improving efficiency.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides a lubrication fixture for a battery vent hole, including a positioning cover for covering the vent hole. The positioning cover has a first through hole corresponding to the vent hole. The positioning cover is movably connected to a fixing block. The fixing block has a second through hole corresponding to the first through hole. A spring-loaded component is movably connected in the second through hole. A lubricating body is fixedly connected to one end of the spring-loaded component near the vent hole. When the spring-loaded component is compressed, the lubricating body can be inserted into the vent hole. When the spring-loaded component is released, the lubricating body is removed from the vent hole.

[0007] Preferably, the rebound assembly includes a fixed guide post and a pressing part, which can move horizontally within the second through hole of the fixing block.

[0008] Preferably, the pressing part is located at the end away from the vent hole and protrudes from the second through hole, a spring is sleeved on the guide post, and the lubricant is inserted into the guide post.

[0009] Preferably, the diameter of the guide post is smaller than the diameter of the pressing part.

[0010] Preferably, a fixed sleeve is fixed on the inner circumferential wall of the second through hole near the vent hole. The outer diameter of the fixed sleeve is larger than the diameter of the guide post, and the guide post and the lubricant can move inside the fixed sleeve.

[0011] Preferably, the positioning cover includes a positioning block, the first through hole is provided on the positioning block, and a handle is provided on the top of the positioning cover.

[0012] Preferably, the outer surface of the positioning block is provided with two vertical and parallel grooves, the first through hole is located between the two grooves, and the side of the fixing block facing the battery is provided with two protrusions that can slide within the grooves.

[0013] Preferably, the cross-section of the protrusion and the groove is trapezoidal, and the end near the vent is the larger end.

[0014] Preferably, the groove includes a groove opening and a groove bottom surface, the groove extending upward to the upper surface of the positioning block to form the groove opening, and the groove bottom surface being lower than the plane where the lowest end of the vent hole is located.

[0015] Preferably, the outer periphery of the lubricant is coated with grease.

[0016] The present invention achieves the following beneficial technical effects compared to the prior art:

[0017] This utility model provides a lubrication fixture for battery vent holes. Because the second through hole, the first through hole, and the vent hole correspond, and because the pressing part, guide post, and lubricant are fixedly connected as a single unit, pressing the pressing part towards the vent hole causes the pressing part, guide post, and lubricant to move towards the vent hole within the second through hole. This allows the lubricant to be precisely inserted into the vent hole, spreading the grease onto the lubricant. At this time, the spring is compressed. When the pressing part is released, the spring force pushes the pressing part away from the vent hole, thereby removing the lubricant from the vent hole. Compared to the prior art of manually applying grease with cotton swabs, this lubrication fixture only requires pressing the pressing part to add grease to the vent hole, saving time and effort. Furthermore, the corresponding arrangement of the second through hole, the first through hole, and the vent hole allows for precise insertion of the lubricant into the vent hole and application of grease, resulting in higher efficiency. Furthermore, this tooling avoids the phenomenon of lubricating grease being applied to the battery cover, ensuring the life of the equipment and preventing the vent from becoming blocked.

Detailed Implementation

[0023] This utility model provides a lubrication fixture for the vent hole of a storage battery, such as... Figures 1-4 As shown, the device includes a positioning cover 1, which is used to cover the vent hole 2 on the battery 3. Specifically, the positioning cover 1 includes a positioning block 4, which has a first through hole 5 corresponding to the vent hole 2. By setting the first through hole 5, the lubricant 15 can pass through the first through hole 5 and enter the vent hole 2, ensuring the accuracy of adding lubricant. It should be noted that the shape and size of the positioning cover 1 can be changed according to the actual size and specifications of the battery 3, as long as the first through hole 5 corresponds to the vent hole 2.

[0024] The positioning cover 1 is detachably connected to a fixing block 6. Specifically, the outer surface of the positioning block 4 has two vertical and parallel grooves 7, and a first through hole 5 is located between the two grooves 7. The side of the fixing block 6 facing the battery 3 has two protrusions 8, each of which can slide within the corresponding groove 7, realizing the vertical sliding connection of the fixing block 6 relative to the positioning cover 1. The groove 7 includes a groove opening 9 and a groove bottom surface 10. The groove 7 extends upward to the upper surface of the positioning block 4 to form the groove opening 9. The groove opening 9 facilitates the downward sliding of the protrusions 8 on the fixing block 6 into the groove 7. The groove bottom surface 10 is lower than the plane where the lowest end of the vent hole 2 is located, so that the lower end of the protrusion 8 can be engaged with the groove bottom surface 10, ensuring connection stability and facilitating the lubricant 15 to pass through the fixing block 6 and enter the vent hole 2. The cross-sections of the protrusions 8 and the grooves 7 are trapezoidal, with the end closer to the vent hole 2 being the larger end. This makes it difficult for the fixing block 6 to fall off the side of the positioning cover 1, ensuring the connection stability of the tooling.

[0025] The fixing block 6 has a second through hole 11 corresponding to the first through hole 5. A spring-loaded assembly is movably connected in the second through hole 11. The spring-loaded assembly includes a fixed guide post 12 and a pressing part 13. The guide post 12 and the pressing part 13 can move horizontally within the second through hole 11 of the fixing block 6. The pressing part 13 is located at the end away from the vent hole 2 and protrudes from the second through hole 11 to facilitate applying pressure to the pressing part 13. The guide post 12 is located at the end close to the vent hole 2. A spring 14 is sleeved on the guide post 12. The diameter of the guide post 12 is smaller than the diameter of the pressing part 13, so that the spring 14 can be compressed when the pressing part 13 is pressed. A lubricant 15 is inserted into the guide post 12. A fixed sleeve 16 is fixedly installed on the inner circumferential wall of the second through hole 11 near the vent hole 2. The guide post 12 and the lubricating body 15 can move within the fixed sleeve 16. The outer diameter of the fixed sleeve 16 is larger than the diameter of the guide post 12, so that when the pressing part 13 is pressed, the spring 14 can be compressed between the fixed sleeve 16 and the pressing part 13. The outer circumference of the lubricating body 15 is coated with grease to apply the grease into the vent hole 2. Specifically, since the second through hole 11, the first through hole 5, and the vent hole 2 correspond to each other, and since the pressing part 13, the guide post 12, and the lubricant 15 are fixed together, when the pressing part 13 is pressed, pressing the pressing part 13 towards the vent hole 2 causes the pressing part 13, the guide post 12, and the lubricant 15 to move towards the vent hole 2 within the second through hole 11. This allows the lubricant 15 to be precisely inserted into the vent hole 2, spreading the lubricant on the lubricant 15 into the vent hole 2. At this time, the spring 14 is compressed. When the pressing part 13 is released, the elastic force of the spring 14 pushes the pressing part 13 away from the vent hole 2, thereby removing the lubricant 15 from the vent hole 2. Compared to the existing technology of manually applying grease with cotton swabs, this lubrication fixture only requires pressing the pressing part 13 when adding grease to the vent hole 2, saving time and effort. Furthermore, due to the corresponding arrangement of the second through hole 11, the first through hole 5, and the vent hole 2, the lubricant 15 can be precisely inserted into the vent hole 2 and the grease can be applied there, resulting in higher efficiency. Moreover, this fixture avoids the phenomenon of grease being applied to the battery cover of the battery 3, ensuring equipment lifespan and preventing clogging of the vent hole 2.

[0026] A handle 17 is provided on the top of the positioning cover 1. By providing the handle 17, it is more convenient to operate the positioning cover 1 when it is placed on the battery 3.

[0027] The lubrication fixture for the vent hole of a battery provided by this utility model, in specific application, firstly covers the top cover of the battery 3 with the positioning cover 1, and aligns the first through hole 5 on the positioning block 4 on the positioning cover 1 with the vent hole 2. Then, the protrusion 8 on the fixing block 6 is inserted from top to bottom into the groove 7 on the positioning block 4, and the second through hole 11 is aligned with the first through hole 5. Then, the pressing part 13 is pressed, so that the lubricating body 15, the guide post 12 and the pressing part 13, which are fixed together, move together in the fixing sleeve 16 toward the vent hole 2, so that the lubricating body 15 is inserted into the vent hole 2, so that the lubricating grease on the lubricating body 15 is applied to the vent hole 2. At this time, the spring 14 is compressed between the fixing sleeve 16 and the pressing part 13. After the application is completed, the pressing part 13 is released, and the elastic force of the spring 14 pushes the pressing part 13 to return to its original position, thereby causing the guide post 12 and the lubricating body 15 to return to their original position. If the grease is insufficient or the lubricant 15 is worn, the retaining block 6 can be removed, and the lubricant 15 can be re-coated with grease or replaced.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
