Description

Technical Field

[0001] This utility model relates to the field of automotive repair technology, and more specifically, to a multifunctional adaptive spark plug sleeve. Background Technology

[0002] A utility model patent with patent number CN201920748377.3 describes a "multifunctional spark plug sleeve," comprising a sleeve, a universal joint, a telescopic outer connecting rod, and a telescopic inner connecting rod. One end of the telescopic inner connecting rod has a groove, and the other end is fitted inside the telescopic outer connecting rod. The telescopic inner connecting rod has several vertically arranged retaining balls. The telescopic outer connecting rod is a hollow structure, fitted onto the telescopic inner connecting rod, and has retaining holes that match the retaining balls. The universal joint includes a connecting rod and a connecting block. The connecting rod has a connecting pin, and one end of the connecting block is rotatably connected to the connecting rod around the connecting pin. The connecting block also has a connecting pin, and one end of the telescopic outer connecting rod is rotatably connected to the connecting block around the connecting pin. The other end of the connecting block is connected to the sleeve. By incorporating the telescopic outer and inner connecting rods, the length of the entire sleeve can be adjusted by changing the position of the telescopic inner connecting rod within the telescopic outer connecting rod, thus accommodating spark plugs with different installation depths.

[0003] However, in actual use, the limiting spring of the above-mentioned utility model will gradually fatigue as the angle of the spark plug sleeve changes, thereby reducing its limiting effect on the spark plug sleeve. Furthermore, the replacement of the limiting spring is also quite troublesome, reducing the work efficiency of technicians. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a multifunctional adaptive spark plug sleeve that can limit the spark plug sleeve when adjusting its angle, reducing the possibility of damage due to excessive rotation and improving the work efficiency of technicians.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A multifunctional adaptive spark plug sleeve includes a sleeve with a universal joint mounted on its upper end. A telescopic rod is fixedly connected to the upper end of the universal joint. A limiting mechanism is provided at the outer end of the universal joint. The limiting mechanism includes a lower connecting ring and an upper limiting ring located outside the universal joint. An annular groove is chiseled at the upper end of the lower connecting ring, and multiple evenly distributed sliding blocks are slidably connected within the annular groove. Multiple evenly distributed connecting blocks are fixedly connected to the bottom end of the upper limiting ring. An elastic rotating rod is rotatably connected to the bottom end of each connecting block, and a connecting nut is fixedly connected to the bottom end of the elastic rotating rod. The connecting nut is located outside the sliding block and threadedly connected to it. This design allows for the limitation of the spark plug sleeve when adjusting its angle, reducing the possibility of damage due to excessive rotation and improving the work efficiency of technicians.

[0009] Furthermore, a contact pad is fixedly connected to the inner wall of the upper limit ring. By setting the contact pad, the universal joint is less likely to be damaged when it comes into contact with the inner wall of the upper limit ring during rotation, thereby improving the service life of the universal joint.

[0010] Furthermore, the cross-section of the annular groove is convex, and a polished layer is provided at the contact points between the annular groove and the sliding block. By providing a polished layer at the contact points between the annular groove and the sliding block, the sliding block is less likely to be obstructed when sliding within the annular groove.

[0011] Furthermore, the upper limit ring, contact pad, and elastic rotating rod are all made of rubber material. The surface of the elastic rotating rod is engraved with anti-slip texture. By using rubber material to make the upper limit ring, contact pad, and elastic rotating rod, the universal joint can be protected when it is twisted, and the possibility of damage due to excessive rotation of the universal joint can be reduced.

[0012] Furthermore, both the connecting nut and the sliding block are fixedly connected to a magnet. The two magnets attract each other. By setting the magnets to attract each other, when installing the lower connecting ring, the connecting nut can be quickly attracted to the sliding block by the action of the magnets, thereby screwing the sliding block into the connecting nut.

[0013] 3. Beneficial effects

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution can limit the spark plug sleeve when adjusting the angle of the spark plug sleeve, reduce the possibility of damage due to excessive rotation, and improve the work efficiency of technicians.

[0016] (2) A contact pad is fixedly connected to the inner wall of the upper limit ring. By setting the contact pad, the universal joint is less likely to be damaged when it comes into contact with the inner wall of the upper limit ring during rotation, thereby improving the service life of the universal joint.

[0017] (3) The cross-section of the annular groove is convex. A polishing layer is provided at the contact point between the annular groove and the sliding block. By setting a polishing layer at the contact point between the annular groove and the sliding block, the sliding block is less likely to be obstructed when sliding in the annular groove.

[0018] (4) The upper limit ring, contact pad and elastic rotating rod are all made of rubber material. The surface of the elastic rotating rod is engraved with anti-slip texture. By using rubber material to make the upper limit ring, contact pad and elastic rotating rod, the universal joint can be protected when it is twisted, and the possibility of damage due to excessive rotation of the universal joint can also be reduced.

[0019] (5) Both the connecting nut and the sliding block are fixedly connected with magnets. The two magnets attract each other. By setting the magnets that attract each other, when installing the lower connecting ring, the connecting nut can be quickly attracted to the sliding block by the action of the magnets, so that the sliding block can be screwed into the connecting nut.

[0029] Example:

[0030] Please see Figure 1-4 A multifunctional adaptive spark plug sleeve includes a sleeve 1, a universal joint 2 mounted on the upper end of the sleeve 1, a telescopic rod 3 fixedly connected to the upper end of the universal joint 2, and a limiting mechanism 4 provided at the outer end of the universal joint 2. The limiting mechanism 4 includes a lower connecting ring 5 and an upper limiting ring 6 located outside the universal joint 2. An annular groove 7 is chiseled at the upper end of the lower connecting ring 5, and multiple evenly distributed sliding blocks 8 are slidably connected in the annular groove 7. Multiple evenly distributed connecting blocks 9 are fixedly connected to the bottom end of the upper limiting ring 6, and an elastic rotating rod 10 is rotatably connected to the bottom end of the connecting blocks 9. A connecting nut 11 is fixedly connected to the bottom end of the elastic rotating rod 10. The connecting nut 11 is located outside the sliding blocks 8 and is threadedly connected to the sliding blocks 8. This design can limit the spark plug sleeve when adjusting the angle, reduce the possibility of damage due to excessive rotation, and improve the work efficiency of technicians.

[0031] Please see Figure 3-4 The upper limit ring 6 has a contact pad 601 fixedly connected to its inner wall. By setting the contact pad 601, the universal device 2 is less likely to be damaged when it comes into contact with the inner wall of the upper limit ring 6 during rotation, thereby improving the service life of the universal device 2. The cross-section of the annular slide groove 7 is convex. The contact area between the annular slide groove 7 and the sliding block 8 is provided with a polished layer. By setting the polished layer at the contact area between the annular slide groove 7 and the sliding block 8, the sliding block 8 is less likely to be obstructed when sliding in the annular slide groove 7.

[0032] Please see Figure 3The upper limit ring 6, contact pad 601, and elastic rotating rod 10 are all made of rubber. The surface of the elastic rotating rod 10 is engraved with anti-slip texture. By using rubber to make the upper limit ring 6, contact pad 601, and elastic rotating rod 10, the universal joint 2 can be protected when it is twisted, and the possibility of damage due to excessive rotation of the universal joint 2 can be reduced. The connecting nut 11 and the sliding block 8 are both fixedly connected with magnets. The two magnets attract each other. By setting the magnets that attract each other, when the lower connecting ring 5 is installed, the connecting nut 11 can be quickly attracted to the sliding block 8 by the action of the magnets, so that the sliding block 8 can be screwed into the connecting nut 11.

[0033] When using this invention, technicians place the upper limit ring 6 on the outside of the universal joint 2, align the connecting nut 11 at the bottom of the elastic rotating rod 10 with the sliding block 8, and rotate the elastic rotating rod 10 by means of the rotation between the elastic rotating rod 10 and the connecting block 9, so that the connecting nut 11 and the sliding block 8 are threadedly connected. When the universal joint 2 is twisted, the buffering effect of the upper limit ring 6, the contact pad 601 and the elastic rotating rod 10 can prevent the universal joint 2 from being damaged, and at the same time protect the universal joint 2 from excessive rotation. Compared with the prior art, this invention can limit the spark plug sleeve when adjusting the spark plug sleeve angle, reduce the possibility of damage due to excessive rotation, and improve the work efficiency of technicians.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
