Description

Technical Field

[0001] This utility model relates to the field of spark plug technology, and in particular to a high-power motorcycle spark plug. Background Technology

[0002] During the assembly and use of high-power motorcycle spark plugs, a protective sleeve is placed on the outside of the insulator to protect it. Traditional fixing methods often use fasteners for locking, lacking a structure that effectively guides and limits the movement of the sleeve. This causes the sleeve to shake or shift during installation and tightening, which not only increases the difficulty of assembly but may also cause mechanical damage to the insulator due to collision or compression of the sleeve.

[0018] 1. 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.

[0019] This invention provides, for example Figure 1 - Figure 4 The high-power motorcycle spark plug shown includes: Spark plug body 1, spark plug body 1 includes an insulator 101, a mounting part is provided at the bottom of the insulator 101, the mounting part is used to fix the position of the insulator 101, and an electrode part is provided at the bottom of the mounting part; Sheath 2 is fitted onto the outer wall of insulator 101, and a through hole 201 is provided at the top of sheath 2; The locking component 3 includes a threaded cylinder 301 disposed at the bottom of the insulator 101, a sheath 2 inserted into the middle of the threaded cylinder 301, the threaded cylinder 301 being used to restrict the movement of the sheath 2, and a fixing member for fixing the position of the sheath 2 being provided at the connection between the sheath 2 and the threaded cylinder 301.

[0020] It should be noted that the through hole 201 is used for the end of the spark plug body 1 to pass through the sheath 2. When it is necessary to fix the position of the sheath 2, the sheath 2 is first inserted into the inside of the threaded cylinder 301, and then the position of the sheath 2 is fixed by the fastener. The threaded cylinder 301 restricts the movement direction of the sheath 2, so as to avoid the sheath 2 from shaking randomly and colliding with the insulator 101 when the position of the sheath 2 is fixed.

[0021] Specifically, the mounting components include a connecting rod 103 located at the bottom of the insulator 101, a fixing thread 105 at the bottom of the connecting rod 103, a sealing gasket 104 fitted in the middle of the connecting rod 103, and a first hexagonal block 102 fitted at the top of the connecting rod 103 for rotating the connecting rod 103. The electrode components include a center electrode 106 inserted and connected to the bottom of the connecting rod 103, and a side electrode 107 fixedly connected to the bottom end of the connecting rod 103.

[0022] It should be noted that the first hexagonal block 102 in the middle of the spark plug is the force-bearing part for tightening or loosening the spark plug with a socket wrench; the fixing thread 105 below is responsible for accurately fixing the spark plug to the engine cylinder head, ensuring that it is in the correct position; there is a sealing gasket 104 between the thread and the rotating block, which is to ensure that the high-pressure gas in the combustion chamber does not leak from here; the core conductive component is the center electrode 106, which is responsible for introducing high-voltage current into the combustion chamber; the current is released through the side electrode 107, which maintains a specific gap with the top of the center electrode 106, generating an electric spark to ignite the air-fuel mixture; and the insulator 101 can withstand extremely high voltage and temperature, ensuring that the current can only flow to the electrode tip along a preset path to prevent leakage.

[0023] Specifically, the fasteners include a threaded sleeve 303 threaded onto the top of the threaded cylinder 301, a sliding hole 306 on the top of the threaded sleeve 303, a sheath 2 inserted into the sliding hole 306, a washer 302 fixedly connected to the top of the first hexagonal block 102, the threaded sleeve 303 being positioned on top of the washer 302, a second hexagonal block 305 being fitted onto the middle of the threaded sleeve 303, the second hexagonal block 305 being used to rotate the threaded sleeve 303, a first limiting ring 304 being fitted onto the bottom of the sheath 2, and a second limiting ring 307 being fitted onto the middle of the sheath 2.

[0024] It should be noted that the first limiting ring 304 and the second limiting ring 307 are both fixedly sleeved on the threaded sleeve 303. The sliding hole 306 is adapted to the protective sleeve 2, so that the threaded sleeve 303 can be sleeved on the protective sleeve 2 through the sliding hole 306. Through this design, the threaded sleeve 303 can slide on the protective sleeve 2. The gasket 302 is made of rubber. The second hexagonal block 305 is fixedly sleeved on the second hexagonal block 305 in the middle of the threaded sleeve 303. In use, a wrench is placed on the second hexagonal block 305, and the second hexagonal block 305 and the threaded sleeve 303 are rotated by the wrench, and the threaded sleeve 303 is tightened by the wrench.

[0025] Furthermore, when it is necessary to fix the position of the sheath 2, first insert the sheath 2 onto the threaded cylinder 301, and make the first limiting ring 304 on the sheath 2 fit against the threaded cylinder 301. Then rotate the threaded sleeve 303 so that the threaded sleeve 303 is threaded onto the threaded cylinder 301, and the threaded sleeve 303 is fixed to the threaded cylinder 301 by the threaded connection. The threaded sleeve 303 presses the first limiting ring 304, and the first limiting ring 304 is pressed and fixed by the compression of the threaded sleeve 303. The position of the sheath 2 is fixed by pressing and fixing the first limiting ring 304.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
