Description

Technical Field

[0001] This utility model belongs to the field of wrench technology, specifically relating to a universal gripping wrench for automotive oil filters. Background Technology

[0002] In the process of car maintenance and repair, the removal and installation of oil filters is a common operation, and a three-jaw wrench is a commonly used tool for removing and installing oil filters.

[0003] Traditional three-jaw grippers, when holding oil filters, have a small contact area and are prone to slippage because only the bar-shaped jaws holding the oil filter are in contact with it. Therefore, there is an urgent need for a new type of gripper that can enhance the contact area and anti-slip performance to solve the slippage problem of traditional tools when installing and removing oil filters. Utility Model Content

[0004] The purpose of this invention is to provide a universal gripping wrench for automotive oil filters, which can reduce slippage of the gripping wrench during the installation and removal of automotive oil filters.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A universal gripper for automotive oil filters includes two main supports. A connecting spindle is rotatably connected between the two main supports at the middle position. A universal wrench is connected to the end of the connecting spindle. A first meshing gear is fixedly connected to the outer side of the connecting spindle. Three second meshing gears are rotatably connected between the two main supports and around the first meshing gear. The three second meshing gears are arranged in a circular array around the axis of the connecting spindle, and the first and second meshing gears are meshed together. A rocker arm is fixedly connected to the outer side of each of the three second meshing gears. A rotating rod is rotatably connected to the rocker arm. A clamping plate is installed at the lower end of the rotating rod. An anti-slip pad is installed on the side of the clamping plate facing the axis of the connecting spindle.

[0007] Furthermore, the universal wrench includes a connecting rod that is connected to the main shaft drive, and the connecting rod is connected to a handle via a universal coupling.

[0008] Furthermore, a sleeve interface is fixedly connected to the end of the connecting spindle, and a square drive head is fixedly connected to the end of the connecting rod away from the universal coupling, the square drive head being snapped into the inside of the sleeve interface.

[0009] Furthermore, a torsion spring is fixedly connected between the rocker arm and the rotating rod.

[0010] Furthermore, the anti-slip pad includes a fixed block and a movable block installed on one side of the clamping plate. The fixed block is fixedly connected to the end of one side of the clamping plate, and the movable block is slidably connected to the clamping plate. A connecting pad is fixedly connected to the outer side of the fixed block and the movable block.

[0011] Furthermore, a connecting ring is fixedly connected to the lower end of the rotating rod, and a rotating shaft is fixedly connected to the rear side of the clamping plate, with the rotating shaft rotatably connected inside the connecting ring.

[0012] Furthermore, a magnet is fixedly connected to the connecting ring, and an iron is fixedly connected to the rotating shaft.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model discloses a universal gripper for automotive oil filters. During the gripping process of an automotive oil filter, the angle of the clamping plate and the anti-slip pad can be automatically adjusted to adapt to the angle of the side of the automotive oil filter. This ensures that there is a large contact area between the anti-slip pad and the side wall of the automotive oil filter, improving the clamping stability of the gripper on the automotive oil filter. As a result, the phenomenon of the gripper slipping can be reduced during the installation and removal of automotive oil filters. Attached Figure Description

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] like Figures 1-4 As shown, a universal gripper for an automotive oil filter includes two main supports 1. A connecting main shaft 2 is rotatably connected between the two main supports 1 at the middle position. A first meshing gear 3 is fixedly connected to the outer side of the connecting main shaft 2. Three second meshing gears 4 are rotatably connected between the two main supports 1 and around the first meshing gear 3. The three second meshing gears 4 are arranged in a circular array with the connecting main shaft 2 as the axis. The first meshing gear 3 and the second meshing gears 4 are meshed together. By rotating the connecting main shaft 2, the first meshing gear 3 can drive the multiple second meshing gears 4 to rotate synchronously.

[0023] A rocker arm 6 is fixedly connected to the outer side of each of the three second meshing gears 4. A rotating rod 7 is rotatably connected to the rocker arm 6. A clamping plate 12 is installed at the lower end of the rotating rod 7. An anti-slip pad is installed on the side of the clamping plate 12 facing the axis of the main shaft 2.

[0024] At this time, when disassembling and assembling the car oil filter, place the gripping wrench on the outside of the car oil filter, so that the three clamping plates 12 are located around the periphery of the car oil filter. Rotating the connecting main shaft 2 will drive the rocker arm 6 to rotate. When the rocker arm 6 rotates, it will drive the clamping plates 12 to rotate together until the anti-slip pads on the clamping plates 12 abut against the side wall of the car oil filter. The clamping plates 12 will automatically rotate under the resistance of the car oil filter, thereby automatically adjusting the angle of the clamping plates 12 and the anti-slip pads to adapt to the angle of the side of the car oil filter, so that the anti-slip pads and the side wall of the car oil filter make surface contact, so that there is a large contact area between the anti-slip pads and the side wall of the car oil filter, improving the clamping stability of the gripping wrench on the car oil filter, thereby reducing the phenomenon of gripping wrench slippage during the disassembly and assembly of the car oil filter.

[0025] A universal wrench is connected to the end of the connecting spindle 2, which allows the user to easily rotate the connecting spindle 2 in different positions.

[0026] Specifically, such as Figures 1-2 As shown, the universal wrench includes a connecting rod 18 that is connected to the main shaft 2 for transmission. The connecting rod 18 is connected to a handle 20 via a universal coupling 19. At this time, when the user is in different positions of the car oil filter, the handle 20 can be rotated through the universal coupling 19 to adjust the angle of the handle 20 so that the angle of the handle 20 is adapted to the user, making it convenient for the user to rotate the handle 20, thereby making it convenient for the user to rotate the main shaft 2.

[0027] The connecting rod 18 can be directly and fixedly connected to the connecting spindle 2, or it can be detachably connected to the connecting spindle 2. In this technical solution, a sleeve interface 5 is fixedly connected to the end of the connecting spindle 2, and a square drive head 21 is fixedly connected to the end of the connecting rod 18 away from the universal coupling 19. The square drive head 21 can be snapped into the inside of the sleeve interface 5. At this time, the snap-fit ​​connection between the sleeve interface 5 and the square drive head 21 is completed by inserting the square drive head 21 into the inside of the sleeve interface 5, thus completing the transmission between the connecting spindle 2 and the connecting rod 18. By setting the sleeve interface 5 and the square drive head 21 separately, the universal wrench can be disassembled and stored.

[0028] Among them, such as Figures 1-2 As shown, a torsion spring 8 is fixedly connected between the rocker arm 6 and the rotating rod 7. The torsion spring 8 can maintain the initial positioning of the rotating rod 7, so that the anti-slip pad on the clamping plate 12 can be automatically positioned to the side opposite to the oil filter inside the gripping wrench.

[0029] One type of anti-slip pad can be a rubber block fixedly connected to the clamping plate 12, with a concave arc-shaped surface on the side of the rubber block away from the clamping plate 12.

[0030] Another structure of anti-slip pads is as follows: Figures 2-3 As shown, the anti-slip pad includes a fixed block 13 and a movable block 16 installed on one side of the clamping plate 12. The fixed block 13 is fixedly connected to the end of one side of the clamping plate 12, and the movable block 16 is slidably connected to the clamping plate 12. A connecting pad 17 is fixedly connected to the outside of the fixed block 13 and the movable block 16. The material of the connecting pad 17 can be rubber.

[0031] like Figure 4 As shown, F1 represents the rotation direction of the sleeve interface 5, and F2 represents the rotation direction of the rocker arm 6. When the sleeve interface 5 is rotated counterclockwise, the rocker arm 6 can be rotated clockwise via the connecting main shaft 2, the first meshing gear 3, and the second meshing gear 4. At this time, the fixed block 13 is located at the front end of the rocker arm 6's rotation direction relative to the movable block 16, i.e., the arrow end. Since the two ends of the connecting pad 17 are fixedly connected to the upper sides of the fixed block 13 and the movable block 16 respectively, one end of the connecting pad 17 is subjected to the force of the fixed block 13. The connection pad 17 is fixed and cannot be moved. When the connecting pad 17 contacts the side of the car oil filter, the connecting pad 17 will pull the movable block 16 to move under the squeezing force exerted by the car oil filter on the connecting pad 17. When the connecting pad 17 is completely in contact with the side of the car oil filter, both the fixed block 13 and the movable block 16 abut against the side of the car oil filter, thereby positioning the connecting pad 17. The connection pad 17 increases the contact area between the anti-slip pad and the car oil filter.

[0032] Specifically, the movable block 16 is installed by opening a groove 14 on one side of the clamping plate 12, and a slider 15 is slidably connected inside the groove 14. The movable block 16 is fixedly connected to the slider 15, so that the sliding connection of the movable block 16 can be completed relatively easily.

[0033] The clamp 12 can be fixedly connected to the rotating rod 7, or it can be rotatably connected to the rotating rod 7. In this technical solution, a rotatable connection is preferred, as detailed below. Figure 2 As shown, a connecting ring 9 is fixedly connected to the lower end of the rotating rod 7, and a rotating shaft 10 is fixedly connected to the rear side of the clamping plate 12. The rotating shaft 10 is rotatably connected inside the connecting ring 9. At this time, the clamping plate 12 can be rotated to change the relative position of the fixed block 13 and the movable block 16 to adapt to the change of the rotation direction of the rocker arm 6.

[0034] A magnet 11 is fixedly connected to the connecting ring 9, and an iron is fixedly connected to the rotating shaft 10. At this time, the rotating shaft 10 can be magnetically positioned by the magnet 11.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
