Description
Technical Field
[0001] This utility model relates to the field of automotive repair technology, and more specifically, to an adjustable torque spark plug sleeve. Background Technology
[0002] In the field of automotive repair and maintenance, spark plugs are a key component of the engine ignition system, and their installation and removal are of paramount importance. Spark plug sockets are an indispensable tool for technicians when operating spark plugs. However, traditional spark plug sockets have revealed many inconveniences in actual use, which greatly affect the work efficiency and operating experience of technicians.
[0003] Traditional spark plug sleeves are typically simple in structure and have a single function, with a significant shortcoming in torque adjustment. Torque, as a physical quantity that measures the magnitude of rotational force, plays a crucial role in the installation and removal of spark plugs. Appropriate torque ensures a good seal between the spark plug and the engine block. It prevents insufficient torque from causing poor sealing, leading to air or oil leaks and affecting the normal operation of the engine, while also preventing excessive torque from damaging the spark plug threads or even the cylinder block threads, increasing repair costs and difficulty. However, in practice, technicians often find it difficult to precisely control the torque using traditional spark plug sleeves.
[0004] Due to the lack of an effective torque adjustment mechanism, technicians can only rely on their own experience and feel to judge the torque when tightening or loosening spark plugs. This method is highly subjective and uncertain. Different technicians have different operating habits and strengths, making it difficult to guarantee that the ideal torque value can be achieved every time. Moreover, traditional spark plug sockets cannot meet the diverse torque requirements when dealing with different specifications and models of spark plugs and engines under different operating conditions. This forces technicians to frequently change tools or use other auxiliary methods, which greatly reduces work efficiency. Utility Model Content
[0005] 1. Technical problems to be solved To address the problems existing in the prior art, the purpose of this utility model is to provide an adjustable torque spark plug sleeve, which makes it more convenient for technicians to adjust the torque when using the spark plug sleeve, thereby improving the work efficiency of technicians.
[0006] Technical solution
[0007] To solve the above problems, the present invention adopts the following technical solution.
[0008] An adjustable torque spark plug sleeve includes a sleeve body. A universal mechanism is mounted on the upper end of the sleeve body, and a telescopic rod is mounted on the upper end of the universal mechanism. An adjustment hole is drilled at the outer end of the telescopic rod, and an adjustment rod is disposed within the adjustment hole. A fixing ring is fixedly connected to the inner wall of the adjustment rod, and a rotating rod is rotatably connected within the fixing ring. Multiple evenly distributed through holes are drilled at the upper end of the adjustment rod, and a contact pad is disposed within the adjustment rod. Multiple evenly distributed locking blocks are fixedly connected to the upper end of the contact pad, and the locking blocks are located within the through holes. The contact pad and the inner wall of the adjustment rod are... Multiple evenly distributed springs are fixedly connected to the rotating rod, with the springs and the locking block spaced apart. A support block is fixedly connected to the upper end of the rotating rod, and the support block is located below the contact pad and in contact with the contact pad. A first connecting rod is fixedly connected to the outer end of the rotating rod, and a locking rod is fixedly connected to the outer end of the first connecting rod. A second connecting rod is fixedly connected to the upper end of the adjusting rod, and a locking groove is chiseled on the outer end of the second connecting rod, with the locking rod located in the locking groove. This design makes it more convenient for technicians to adjust the torque when using the spark plug sleeve, thus improving the efficiency of the technicians' work.
[0009] Furthermore, a polished layer is provided at the rotatable connection between the fixed ring and the rotating rod. By providing the polished layer, the rotating rod can rotate more smoothly within the fixed ring, thereby making torque adjustment more convenient.
[0010] Furthermore, both the locking rod and the second connecting rod are fixedly connected with magnet blocks inside. The two magnet blocks attract each other. By setting the magnet blocks that attract each other, the locking rod and the second connecting rod are not easy to separate, thereby improving the stability when the rotating rod is locked.
[0011] Furthermore, the spring is made of stainless steel and its surface is coated with an anti-rust paint layer. By using stainless steel to make the spring and coating its surface with anti-rust paint, the spring is less prone to corrosion during long-term use, thereby improving its service life.
[0012] Furthermore, the distance between the upper and lower inner walls of the slot is greater than the thickness of the lever, and an elastic pad is fixedly connected to the inner wall of the slot. By setting the distance between the upper and lower inner walls of the slot to be greater than the thickness of the lever, the lever can be locked into the slot when the rotating rod is rotated, thus locking the position of the rotating rod. Beneficial effects
[0013] Compared with existing technologies, the advantages of this utility model are: (1) This solution makes it easier for technicians to adjust the torque when using spark plug sleeves, thus improving their work efficiency.
[0014] (2) A polished layer is provided at the connection between the fixed ring and the rotating rod. By setting the polished layer, the rotating rod can rotate more smoothly in the fixed ring, thus making the torque adjustment work more convenient.
[0015] (3) Both the locking rod and the connecting rod are fixedly connected with magnet blocks. The two magnet blocks attract each other. By setting the magnet blocks that attract each other, the locking rod and the connecting rod are not easy to separate, thereby improving the stability when the rotating rod is locked.
[0016] (4) The spring is made of stainless steel and the surface of the spring is coated with anti-rust paint. By using stainless steel to make the spring and coating its surface with anti-rust paint, the spring is less likely to be corroded during long-term use, thereby improving the service life of the spring.
[0017] (5) The distance between the upper and lower inner walls of the slot is greater than the thickness of the lever. An elastic pad is fixedly connected to the inner wall of the slot. By setting the distance between the upper and lower inner walls of the slot to be greater than the thickness of the lever, the lever can be locked into the slot when the rotating lever is rotated.

[0023] Please see Figure 1-4 An adjustable torque spark plug sleeve includes a sleeve body 1, a universal mechanism 2 mounted on the upper end of the sleeve body 1, a telescopic rod 3 mounted on the upper end of the universal mechanism 2, an adjustment hole 4 drilled at the outer end of the telescopic rod 3, an adjustment rod 5 disposed within the adjustment hole 4, a fixing ring 6 fixedly connected to the inner wall of the adjustment rod 5, a rotating rod 7 rotatably connected within the fixing ring 6, multiple evenly distributed through holes 8 drilled at the upper end of the adjustment rod 5, a contact pad 9 disposed within the adjustment rod 5, multiple evenly distributed locking blocks 10 fixedly connected to the upper end of the contact pad 9, the locking blocks 10 being located within the through holes 8, and a fixed connection between the contact pad 9 and the inner wall of the adjustment rod 5. There are multiple evenly distributed springs 11, which are spaced apart from the locking blocks 10. A support block 12 is fixedly connected to the upper end of the rotating rod 7. The support block 12 is located on the lower side of the contact pad 9 and is in contact with the contact pad 9. A first connecting rod 13 is fixedly connected to the outer end of the rotating rod 7. A locking rod 14 is fixedly connected to the outer end of the first connecting rod 13. A second connecting rod 15 is fixedly connected to the upper end of the adjusting rod 5. A locking groove 16 is chiseled on the outer end of the second connecting rod 15. The locking rod 14 is located in the locking groove 16. This makes it more convenient for technicians to adjust the torque when using the spark plug sleeve, thus improving the efficiency of the technicians' work.
[0024] Please see Figure 2-4A polished layer is provided at the rotatable connection between the fixed ring 6 and the rotating rod 7. By setting the polished layer, the rotating rod 7 can rotate more smoothly within the fixed ring 6, thus making the torque adjustment work more convenient. Magnet blocks are fixedly connected inside both the locking rod 14 and the second connecting rod 15. The two magnet blocks attract each other. By setting the mutually attracting magnet blocks, the locking rod 14 and the second connecting rod 15 are not easy to separate, thereby improving the stability of the rotating rod 7 when the position is locked.
[0025] Please see Figure 3-4 The spring 11 is made of stainless steel and has a rust-proof paint coating. By using stainless steel to make the spring 11 and coating it with rust-proof paint, the spring 11 is less prone to corrosion during long-term use, thereby improving its service life. The distance between the upper and lower inner walls of the slot 16 is greater than the thickness of the lever 14. An elastic pad 1601 is fixedly connected to the inner wall of the slot 16. By setting the distance between the upper and lower inner walls of the slot 16 to be greater than the thickness of the lever 14, the lever 14 can be locked into the slot 16 when the rotating rod 7 is rotated, thus locking the position of the rotating rod 7.
[0026] When using this invention, technicians insert the adjusting rod 5 into the adjusting hole 4, select a suitable position, and rotate the rotating rod 7 so that the locking rod 14 is engaged in the locking groove 16. Under the squeezing action of the support block 12 on the contact pad 9, the support block 12 pushes the contact pad 9 upward, thereby causing the locking block 10 to extend out of the through hole 8, so that the spring 11 is engaged in the adjusting hole 4. The opening of the adjusting hole 4 is located between two adjacent springs 11. Compared with the prior art, this invention makes it more convenient for technicians to adjust the torque when using the spark plug sleeve, thus improving the work efficiency of technicians.
