Description

Technical Field

[0001] The utility model relates to the technical field of sealing plugs, in particular to a sealing plug for an engine. Background Technique

[0002] An engine is a complex machine composed of many mechanisms and systems. Its overall structure and quality play a decisive role in the motion performance, economic performance, and emission performance of an automobile. The basic structure of an engine mainly consists of a crank connecting rod mechanism, a valve train, a fuel supply system, a cooling system, a lubrication system, an ignition system, a starting system, and various accessories and attachments required for the engine to work. These mechanisms and systems each undertake different tasks but cooperate together to ensure the normal operation of the engine. In the engine liquid tank, a sealing plug is needed to seal it. Its design aims to ensure the sealing of the liquid inside the engine, prevent leakage, and ensure the normal operation of the engine.

[0003] Patent document CN204187202U discloses a sealing plug for an engine, which discloses that "it includes a screw head and a threaded part connected to the screw head. The threaded part is a hollow structure, and one end away from the screw head is open. The sealing plug for an engine provided by the embodiment of the utility model greatly reduces the weight and cost by setting the threaded part as a hollow structure."

[0004] However, the sealing plug for an engine in the above-mentioned published literature mainly considers that by setting the threaded part as a hollow structure, the weight is greatly reduced and the cost is also significantly reduced. It is not convenient to add liquid to the inside of the engine and does not require disassembling the sealing plug for liquid addition. Because when adding liquid to the engine liquid tank, it is necessary to rotate the sealing plug to remove it from the inlet and outlet before adding liquid. And the existing sealing studs will be damaged after long-term installation and disassembly, resulting in poor sealing.

[0005] In view of this, it is necessary to research a liquid adding mechanism, which can facilitate adding liquid to the inside of the engine without disassembling the sealing plug for liquid addition. Content of the Utility Model

[0006] The purpose of the utility model is to provide a sealing plug for an engine to solve the technical problem of enabling the sealing plug for an engine to have a convenient liquid adding function as mentioned in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A sealing plug for an engine, comprising: a sealing plug top cover, a sealing stud is installed at the bottom of the sealing plug top cover, a sealing block is installed at the bottom of the sealing stud, and a liquid adding mechanism is arranged on the inner wall of the sealing plug top cover. The liquid adding mechanism is used to facilitate adding liquid to the inside of the engine without disassembling the sealing plug for liquid addition;

[0008] The liquid adding mechanism includes a liquid adding tank which is arranged on the inner wall of the sealing plug top cover, and one end of the liquid adding tank extends into the inside of the sealing block. A metering rod is installed on the inner wall of the liquid adding tank, and a metering floating plate is installed around the outer wall of the metering rod. A locking hole is provided at the top of the sealing plug top cover, a first magnetic block is installed on the inner wall of the locking hole, a second magnetic block is installed on the outer wall of the first magnetic block, a plugging block is installed on the outer wall of the second magnetic block, a supporting block is installed on the inner wall of the liquid adding tank, and a filter screen layer is installed on the outer wall of the supporting block.

[0009] Preferably, a disassembly mechanism is provided on the outer wall of the sealing block, and the disassembly mechanism is used to facilitate the disassembly and replacement of the sealing block.

[0010] Preferably, the disassembly mechanism includes a disassembly and installation groove which is arranged on the outer wall of the sealing stud.

[0011] Preferably, a disassembly and installation post is installed on the outer wall of the sealing block, and a clamping groove is provided on the outer wall of the disassembly and installation post.

[0012] Preferably, a clamping channel is provided on the outer wall of the sealing stud, and one end of the clamping channel extends into the inside of the disassembly and installation groove.

[0013] Preferably, a sliding rod is installed on the inner wall of the clamping channel, a sliding block is installed around the outer wall of the sliding rod, a clamping post is installed on the outer wall of the sliding block, a locking block is installed on the outer wall of the sliding rod, and a locking groove is provided on the outer wall of the sliding block.

[0014] Preferably, a long rod is installed on the outer wall of the locking block, and one end of the long rod extends into the inside of the locking groove.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By installing the liquid adding mechanism, it is convenient to add liquid to the inside of the engine without disassembling the sealing stud for liquid adding. When adding liquid to the engine liquid tank, it is necessary to rotate the sealing stud and remove it from the inlet and outlet for liquid adding. However, the existing sealing stud will be damaged after long-term disassembly and installation, resulting in poor sealing. Therefore, it is necessary to facilitate the liquid adding to the engine liquid tank. First, pull the plugging block to remove the second magnetic block from the first magnetic block, and then add liquid to the engine liquid tank through the liquid adding tank. At the same time, during liquid adding, the filter screen layer can be taken and placed in the supporting block to filter the particulate matter in the added liquid according to requirements. During the liquid adding process, the movement of the metering floating plate on the metering rod can be observed to determine whether to continue adding liquid. After liquid adding is completed, use the plugging block to seal the liquid adding tank. At the same time, according to the magnet adsorption situation, the position of the plugging block can also be stabilized by using bolts and magnets synchronously, thereby facilitating the liquid adding to the engine liquid tank;

[0017] 2. The utility model is provided with a disassembly mechanism, which facilitates the disassembly and replacement of the sealing block. The sealing block will be worn after long-term use, resulting in poor sealing. The existing sealing blocks are often fixedly connected. When the sealing block is damaged, the whole sealing plug needs to be replaced, increasing the replacement cost. Therefore, it is necessary to improve this situation. First, when the sealing block needs to be disassembled, the long rod is first taken out from the locking groove, and then the clamping column is pulled, so that the sliding block moves on the sliding rod, and the clamping column is removed from the clamping groove. At this time, the sealing block is pulled, so that the installation and disassembly column is removed from the installation and disassembly groove, and the sealing block is disassembled. The installation is also operated in this way, which facilitates the installation and disassembly of the sealing block and reduces the later replacement cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figure 2 and Figure 3, the inner wall of the sealing plug top cover 1 is provided with a liquid adding mechanism. The liquid adding mechanism is used to facilitate the liquid addition to the engine interior without disassembling the sealing plug for liquid addition. The liquid adding mechanism includes a liquid adding groove 4. The liquid adding groove 4 is arranged on the inner wall of the sealing plug top cover 1, and one end of the liquid adding groove 4 extends into the interior of the sealing block 3. A metering rod 5 is installed on the inner wall of the liquid adding groove 4. A metering floating plate 6 is installed around the outer wall of the metering rod 5. A locking hole 7 is provided at the top of the sealing plug top cover 1. A first magnet 8 is installed on the inner wall of the locking hole 7. A second magnet 9 is installed on the outer wall of the first magnet 8. A plugging block 10 is installed on the outer wall of the second magnet 9. A supporting block 11 is installed on the inner wall of the liquid adding groove 4. A filter screen layer 12 is installed on the outer wall of the supporting block 11. When adding liquid to the engine liquid tank, it is necessary to rotate the sealing plug and remove it from the inlet and outlet to add liquid. However, the existing sealing stud 2 may be damaged after long-term installation and disassembly, resulting in poor sealing. Therefore, it is necessary to facilitate the liquid addition to the engine liquid tank. First, pull the plugging block 10 to remove the second magnet 9 from the first magnet 8. Then, add liquid to the engine liquid tank through the liquid adding groove 4. At the same time, when adding liquid, the filter screen layer 12 can be taken and placed in the supporting block 11 to filter the particulate matter in the added liquid according to the needs. During the liquid adding process, the movement of the metering floating plate 6 on the metering rod 5 can be observed to determine whether to continue adding liquid. After the liquid addition is completed, use the plugging block 10 to seal the liquid adding groove 4. At the same time, according to the magnet adsorption situation, the position of the plugging block 10 can also be stabilized by using bolts and magnets synchronously, thereby facilitating the liquid addition to the engine liquid tank.

[0029] Please refer to Figure 4 and Figure 5, a disassembly mechanism is provided on the outer wall of the sealing block 3. The disassembly mechanism is used to facilitate the disassembly and replacement of the sealing block 3. The disassembly mechanism includes an installation and disassembly groove 13, which is arranged on the outer wall of the sealing stud 2.

A locking groove 22 is provided on the outer wall of the slider 18. A long rod 21 is installed on the outer wall of the locking block 20, and one end of the long rod 21 extends into the interior of the locking groove 22. The sealing block 3 may be worn after long-term use, resulting in poor sealing. The existing sealing block 3 is often fixedly connected. When the sealing block 3 is damaged, the entire sealing plug needs to be replaced, increasing the replacement cost. Therefore, it is necessary to improve this. First, when the sealing block 3 needs to be disassembled, first take out the long rod 21 from the locking groove 22, and then pull the clamping column 19. Then the slider 18 moves on the sliding rod 17, so that the clamping column 19 is removed from the clamping groove 15. At this time, pull the sealing block 3 to remove the installation and disassembly column 14 from the installation and disassembly groove 13, and then disassemble the sealing block 3. The installation is also operated in this way, which facilitates the installation and disassembly of the sealing block 3 and reduces the later replacement cost.

When refueling the engine liquid tank, it is necessary to rotate the sealing plug and remove it from the inlet and outlet before refueling. However, the existing sealing stud 2 may be damaged after long-term installation and removal, resulting in poor sealing. Therefore, it is necessary to facilitate refueling of the engine liquid tank. First, pull the plugging block 10 to remove the second magnetic block 9 from the first magnetic block 8. Then, refuel the engine liquid tank through the refueling groove 4. At the same time, when refueling, a filter screen layer 12 can be taken and placed in the supporting block 11 to filter the particulate matter during refueling according to requirements. During the refueling process, the movement of the quantitative floating plate 6 on the quantitative rod 5 can be observed to determine whether to continue refueling. After refueling, use the plugging block 10 to seal the refueling groove 4. At the same time, according to the magnet adsorption situation, the position of the plugging block 10 can also be stabilized by using bolts and magnets synchronously, thus facilitating refueling of the engine liquid tank. The sealing block 3 may be worn after long-term use, resulting in poor sealing. The existing sealing block 3 is often fixedly connected. When the sealing block 3 is damaged, the entire sealing plug needs to be replaced, increasing the replacement cost. Therefore, it is necessary to improve this. First, when it is necessary to disassemble the sealing block 3, first take out the long rod 21 from the locking groove 22. Then, pull the locking column 19, and the slider 18 moves on the sliding rod 17, so that the locking column 19 is removed from the locking groove 15. At this time, pull the sealing block 3 to remove the disassembly and installation column 14 from the disassembly and installation groove 13, and then disassemble the sealing block 3. The installation is also operated in this way, thus facilitating the disassembly and installation of the sealing block 3 and reducing the later replacement cost.
