Technical Field
[0001] The utility model relates to the technical field of screw plugs, and in particular to a lightweight high-pressure shell screw plug for new energy vehicles. Background Art
[0002] Screw plugs are needed in the production of new energy vehicles. Screw plugs are a mechanical fastener used to fix and connect two parts. Its main function is to make the fixed parts fit tightly to prevent loosening due to vibration or external force, and to seal through threads and sealing gaskets to prevent medium leakage.
[0003] However, after the existing screw plugs are used for a long time, the external threads may rust and become difficult to twist. Usually, lubricating oil needs to be applied, but it is difficult for the lubricating oil to pass through the gaps between the screw plugs and thus it is not easy to play a lubricating role. The lubricating effect is not great. Therefore, a lightweight high-pressure shell screw plug for new energy vehicles is needed. Utility Model Content
[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a lightweight high-pressure shell plug for new energy vehicles, which can solve the problem that the external thread of the plug may rust after being used for a long time, making it difficult to twist, and the lubricating oil is difficult to pass through the gap between the plugs, making it difficult to play a lubricating role.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a lightweight high-pressure shell plug for new energy vehicles, comprising an upper plug and a lubricating oil extrusion structure, the bottom of the upper plug is welded with a lower plug, the lubricating oil extrusion structure comprises a moving part, a piston rod, a sliding rod, a spring, and a piston, the moving part is slidably connected to the inside of the upper plug, the piston rod is fixedly connected to the moving part, the piston is slidably connected to the inside of the lower plug, the piston is fixedly connected to the piston rod, the number of sliding rods is multiple and all are fixedly connected to the moving part, each sliding rod is slidably connected to the upper plug, the number of springs is the same as the sliding rods and all are fixedly connected to the sliding rods, and the other end of each spring is fixedly connected to the upper plug.
[0006] Preferably, a lubricating oil containing groove is opened inside the lower part of the screw plug.
[0007] Preferably, the internal threaded connection of the lower portion of the screw plug is provided with a sealing bolt.
[0008] Preferably, a plurality of oil outlet holes are provided inside the lower portion of the screw plug, and a permeable net is fixedly connected inside each oil outlet hole.

[0010] Preferably, the outer surface of the lower portion of the screw plug is provided with an external thread.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] (1) The lightweight high-pressure housing screw plug for new energy vehicles squeezes the lubricating oil in the lubricating oil holding groove through the oil outlet hole by means of a piston. After being squeezed out of the oil outlet hole, the lubricating oil adheres to the outer wall of the lower part of the screw plug and produces a good lubricating effect. The screw plug can then be easily screwed out, thus solving the problem that the outer thread of the screw plug may rust after being used for a long time, making it difficult to screw it, and the lubricating oil is difficult to pass through the gap between the screw plugs, making it difficult to play a lubricating role. This makes it easier to screw out the screw plug, thus increasing its practicality.
[0013] (2) The lightweight high-pressure housing screw plug for new energy vehicles has a permeable net to prevent dust from entering the interior of the lubricating oil. The hexagonal grooves of different sizes enable the screw plug to adapt to screwdrivers of different sizes, making it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 1-2 The utility model provides a technical solution: a lightweight high-pressure shell plug for new energy vehicles, including a plug upper part 1 and a lubricating oil extrusion structure. The bottom of the plug upper part 1 is welded with a plug lower part 2. The lubricating oil extrusion structure includes a moving part 4, a piston rod 8, a sliding rod 9, a spring 10, and a piston 14. The moving part 4 is slidably connected to the inside of the plug upper part 1, the piston rod 8 is fixedly connected to the moving part 4, the piston 14 is slidably connected to the inside of the plug lower part 2, the piston 14 is fixedly connected to the piston rod 8, the number of sliding rods 9 is multiple and all are fixedly connected to the moving part 4, each sliding rod 9 is slidably connected to the plug upper part 1, the number of springs 10 is the same as that of the sliding rods 9 and all are fixedly connected to the sliding rods 9, and the other end of each spring 10 is fixedly connected to the plug upper part 1.
[0023] Furthermore, a lubricating oil containing groove 15 is provided inside the lower part 2 of the screw plug, and a sealing bolt 13 is connected to the internal thread of the lower part 2 of the screw plug. A plurality of oil outlet holes 11 are provided inside the lower part 2 of the screw plug, and a penetration net 12 is fixedly connected to the inside of each oil outlet hole 11. The penetration net 12 can prevent dust from entering the interior of the lubricating oil. When the screw plug is screwed, the moving part 4 will drive the piston rod 8 to move, and the movement of the piston rod 8 will drive the piston 14 to move. The piston 14 moves along the inner wall of the lubricating oil containing groove 15 and squeezes the lubricating oil inside the lubricating oil containing groove 15 through the oil outlet holes 11. After the lubricating oil is squeezed out from the oil outlet holes 11, it will adhere to the outer wall of the lower part 2 of the screw plug and produce a good lubricating effect. Then the screw plug can be easily screwed out. The setting of the lubricating oil extrusion structure solves the problem that the external thread of the screw plug may rust and become difficult to screw after being used for a long time, and the lubricating oil is difficult to pass through the gap between the screw plugs, resulting in difficulty in lubrication. This makes it more convenient to screw out the screw plug and increases practicality.
[0024] Secondly, the interior of the movable part 4 is respectively provided with a first hexagonal inner groove 5, a second hexagonal inner groove 6 and a third hexagonal inner groove 7, and the outer surface of the lower part 2 of the screw plug is provided with an external thread 3. Through hexagonal grooves of different sizes, the screw plug can be adapted to screwdrivers of different sizes, which is more convenient to use. The upper part 1 of the screw plug and the lower part 2 of the screw plug are both made of lightweight aluminum profiles, which not only retains the excellent performance of traditional aluminum profiles, but also has higher strength and better corrosion resistance, thereby improving the durability of the screw plug.
[0025] Working principle: When the screw plug is turned, the moving part 4 will drive the piston rod 8 to move, and the movement of the piston rod 8 will drive the piston 14 to move. The piston 14 moves along the inner wall of the lubricating oil containing groove 15 and squeezes the lubricating oil inside the lubricating oil containing groove 15 through the oil outlet hole 11. After the lubricating oil is squeezed out from the oil outlet hole 11, it will adhere to the outer wall of the lower part 2 of the screw plug and produce a better lubricating effect. Then the screw plug can be easily screwed out, and the lubricating oil can be stored in the inside of the lubricating oil containing groove 15 through the sealing bolt 13.
[0026] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
