Description

Technical Field

[0001] This utility model relates to the field of hand tools, and more particularly to disassembly and assembly tools. Background Technology

[0002] An oil filter, also known as an engine oil filter, is primarily used to remove impurities such as dust, metal particles, carbon deposits, and soot particles from engine oil, protecting the engine. Therefore, to ensure the effectiveness of the oil filter and achieve engine protection, it is essential to maintain and replace the oil filter regularly.

[0003] Because different car models have different oil filter sizes, existing removal and installation tools have a certain range of specifications and can only be used for oil filters within that range, so their applicability is generally limited. Secondly, because the space for installing oil filters in cars is small, existing removal and installation tools are bulky and inconvenient to use. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, one of the objectives of this utility model is to provide a small and easy-to-use disassembly and assembly tool that can be used with different sizes of oil filters.

[0005] One of the objectives of this utility model is achieved through the following technical solution:

[0006] The disassembly and assembly tool includes a base, a rotating component, a toggle switch, a clamping block assembly, and a locking assembly. The rotating component is rotatably mounted on the base and includes a ratchet. The clamping block assembly includes multiple clamping blocks movably connected to each other to switch between a retracted and an open state. Each clamping block is rotatably connected to the base. The locking assembly includes a first pawl and a second pawl, the ratchet teeth of which face opposite directions. The toggle switch is mounted on the base and abuts against the first pawl, causing the first pawl to... When the pawl engages with the ratchet, and the rotating member rotates around the first direction under external force, the first pawl and the ratchet lock together, and the rotating member drives the multiple clamping blocks and the parts to be disassembled held by the multiple clamping blocks to rotate around the first direction; when the toggle button abuts against the second pawl, causing the second pawl to engage with the ratchet, and the rotating member rotates around the second direction opposite to the first direction under external force, the second pawl and the ratchet lock together, and the rotating member drives the multiple clamping blocks and the parts to be disassembled held by the multiple clamping blocks to rotate around the second direction.

[0007] Furthermore, the clamping block assembly also includes a first elastic element, the two ends of which are fixedly connected to the two clamping blocks respectively.

[0008] Furthermore, the number of clamping blocks is two, and the two clamping blocks are slidably connected.

[0009] Furthermore, the two clamping blocks are a first clamping block and a second clamping block. The first clamping block includes a first clamping part and a slider extending from the first clamping part. The second clamping block includes a second clamping part and a mounting plate extending from the second clamping part. The mounting plate is provided with a receiving space. The slider is slidably mounted in the receiving space. The first clamping part and the second clamping part form a clamping space.

[0010] Furthermore, both the first clamping part and the second clamping part are provided with anti-slip textures on the side facing the clamping space.

[0011] Furthermore, the slider is provided with a groove, the mounting plate is provided with a mounting hole, the axis of the mounting hole is perpendicular to the extension direction of the groove, and the clamping block assembly also includes a guide post, the guide post is located in the groove and the guide post is fixed to the mounting hole.

[0012] Furthermore, the disassembly and assembly tool also includes connecting rods, the number of which is the same as the number of clamping blocks. One end of each connecting rod is rotatably connected to the clamping block, and the other end of each connecting rod is rotatably connected to the base.

[0013] Furthermore, there are two clamping blocks. When the two clamping blocks are in the open state, the two connecting rods are on the same straight line. When the two clamping blocks are in the closed state, the two connecting rods abut against each other.

[0014] Furthermore, the locking assembly also includes two second elastic elements. Both the first pawl and the second pawl are rotatably mounted on the base. One end of one second elastic element abuts against the base and the other end abuts against the first pawl; the other second elastic element abuts against the base and the other end abuts against the second pawl.

[0015] Furthermore, the contact point between the toggle switch and the first pawl is located between the rotation point of the first pawl and the contact point between the first pawl and the second elastic element.

[0016] Furthermore, the toggle switch simultaneously abuts against both the first pawl and the second pawl.

[0017] Furthermore, the dial includes an operating part and an abutment part fixedly connected to the operating part. The abutment part has a triangular cross-section. The operating part is rotatably mounted on the base. The abutment part abuts against both the first pawl and the second pawl.

[0018] Furthermore, when the first pawl engages with the ratchet, the second pawl disengages from the ratchet; when the second pawl engages with the ratchet, the first pawl disengages from the ratchet.

When a component is said to be "connected to" another component, it can be directly connected to the other component or it may be fixed through another intermediate component. When a component is said to be "set on" another component, it can be set directly on the other component or it may be set through another intermediate component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] This application's disassembly and assembly tool installs or removes the component to be disassembled by rotation; the rotation direction is reversed when installing or removing the component. In this embodiment, the component to be disassembled is an oil filter, and a wrench provides clockwise or counterclockwise rotational power to the disassembly and assembly tool. Since different brands of oil filters have different sizes, this application's disassembly and assembly tool can switch between a retracted state and an open state to accommodate components of different specifications.

[0040] Please see Figure 1 , Figure 2 as well as Figure 3 The disassembly / assembly tool includes a rotating component 10, a base 20, a toggle switch 30, a connecting rod 40, a clamping block assembly 50, and a locking assembly 60. The rotating component 10 is rotatably mounted on the base 20 and is used to mount a wrench to input the rotational driving force. The base 20 transmits power through the connecting rod 40 to the clamping block assembly 50, causing the clamping block assembly 50 to rotate the component to be disassembled / assembled. The toggle switch 30 controls the direction in which the locking assembly 60 engages with the rotating component 10, allowing the rotating component 10 to change the direction it drives the component to be disassembled / assembled. The clamping block assembly 50 is used to clamp or release components of different sizes to be installed. The locking assembly 60 is mounted on the base 20 and engages in a different direction from the rotating component 10, allowing the power from the rotating component 10 to be transmitted to the clamping block assembly 50.

[0041] The rotating component 10 is cylindrical in shape. A wrench hole 11 is provided at the top of the rotating component 10 for mounting a wrench. A ratchet 12 is provided on the side wall at the bottom of the rotating component 10, which engages with the pawl 61 to lock and transmit power. The rotating component 10 is rotatably mounted on the base 20, with the wrench hole 11 exposed outside the base 20 and the ratchet 12 located inside the base 20.

[0042] The base 20 is used to mount the rotating component 10, the toggle switch 30, and the locking assembly 60 to protect these components and prevent damage. The base 20 also transmits the rotational driving force. The base 20 includes an upper cover 21 and a lower cover 22, which are fixedly connected. The rotating component 10 and the toggle switch 30 are rotatably mounted on the upper cover 21, and the locking assembly 60 is located between the upper cover 21 and the lower cover 22.

[0043] A toggle switch 30 is mounted on the base 20 and is used to control the direction in which the locking assembly 60 and the rotating member 10 engage. Specifically, the toggle switch 30 is rotatably mounted on the base 20 and includes an operating part 31 and an abutment part 32 extending from the operating part 31. The operating part 31 is located outside the base 20 for easy user operation, while the abutment part 32 is located inside the base 20 and simultaneously abuts against both the first pawl 610 and the second pawl 611. Because the cross-section of the abutment part 32 is polygonal, the abutment amplitude of the abutment part 32 against the first pawl 610 and the second pawl 611 is different, causing one of the first pawl 610 and the second pawl 611 to engage with the ratchet 12 while the other disengages from the ratchet 12. In this embodiment, the cross-section of the abutment part 32 is triangular.

[0044] Please see Figure 6 The number of connecting rods 40 is the same as the number of clamping blocks. One end of each connecting rod 40 is rotatably connected to a clamping block, and the other end of each connecting rod 40 is rotatably connected to the lower cover 22 of the base 20. In this embodiment, there are two connecting rods 40. When the two clamping blocks move to their open limit positions, the two connecting rods 40 are on the same straight line. When the two clamping blocks move to their closed limit positions, the two connecting rods 40 abut against each other. Each connecting rod 40 includes a rod body 41, a first rotating shaft 42, and a second rotating shaft 43. One end of the rod body 41 is rotatably connected to the clamping block via the first rotating shaft 42, and the other end of the rod body 41 is rotatably connected to the lower cover 22 via the second rotating shaft 43.

[0045] Please see Figure 4The clamping block assembly 50 includes multiple clamping blocks that are movably connected, allowing the clamping blocks to switch between an open state and a closed state. In this embodiment, the clamping block assembly 50 includes a first clamping block 51, a second clamping block 52, a first elastic member 53, and a guide post 54. The first clamping block 51 and the second clamping block 52 are slidably connected. Specifically, the first clamping block 51 includes a first clamping portion 510, a slider 511 extending from the first clamping portion 510, and a first mounting base 512. The first clamping portion 510 extends vertically, and the slider 511 extends horizontally. The first clamping portion 510 has a first anti-slip texture 5102 on the side facing the second clamping portion 520, which prevents the clamping block assembly 50 from slipping on the part to be disassembled or assembled. The first clamping portion 510 also has a first fixing hole 5101 for fixing the first elastic member 53, which is a spring. The first mounting base 512 is located at the bottom of the first clamping part 510 and is used to rotate the mounting link 40. The slider 511 is provided with a sliding groove 5110 for sliding between the first clamping block 51 and the second clamping block 52. The second clamping block 52 includes a second clamping part 520, a mounting plate 521, and a second mounting base 522. The second clamping part 520 extends vertically and has a second anti-slip texture 5202 on its sidewall facing the first clamping part 510. The second anti-slip texture 5202 is used to prevent the clamping block assembly 50 from slipping with the part to be disassembled. The second clamping part 520 is provided with a second fixing hole 5201 for fixing the first elastic member 53. The mounting plate 521 extends horizontally and has a receiving space 5210 and a mounting hole 5211. The receiving space 5210 extends horizontally, and the axis of the mounting hole 5211 extends vertically. The slider 511 slides within the receiving space 5210, and the guide post 54 is fixed to the mounting hole 5211 and located in the slide groove 5110. The second mounting base 522 is used to rotate and mount the connecting rod 40. In this embodiment, there are two first elastic elements 53, which are located on both sides of the clamping block assembly 50. The two first elastic elements 53 are in a stretched state, and the elastic force of the two first elastic elements 53 causes the first clamping block 51 and the second clamping block 52 to automatically retract.

[0046] Please see Figure 5The locking assembly 60 includes a pawl 61, a second elastic element 62, and a third rotating shaft 63. The pawl 61 includes a first pawl 610 and a second pawl 611. There are two second elastic elements 62 and two third rotating shafts 63. Both the first pawl 610 and the second pawl 611 have ratchet teeth at their ends. One end of each of the first pawl 610 and the second pawl 611 is rotatably mounted to the lower cover 22 via the third rotating shaft 63. One end of one second elastic element 62 abuts against the lower cover 22, and the other end abuts against the first pawl 610. The other second elastic element 62 abuts against the lower cover 22, and the other end abuts against the second pawl 611. When the lever 30 is engaged, only one of the first pawl 610 and the second pawl 611 engages with the ratchet 12, while the other disengages.

[0047] Please see Figures 5 to 8 When assembling and disassembling the tool, the rotating part 10 and the toggle switch 30 are rotatably mounted on the base 20. The toggle switch 30 abuts against the first pawl 610 and the second pawl 611. Because the cross-section of the abutting part 32 is polygonal, the abutting part 32 abuts against the first pawl 610 and the second pawl 611 with different abutting amplitudes, causing the first pawl 610 to engage with the ratchet 12 and the second pawl 611 to disengage from the ratchet 12. The base 20 is rotatably connected to the first clamping block 51 and the second clamping block 52 respectively via two connecting rods 40.

[0048] When using disassembly / assembly tools, the initial state of the tools is as follows: Figure 5 as well as Figure 6 As shown, pry open the first clamping block 51 and the second clamping block 52. At this time, the disassembly and assembly tools are as follows: Figure 7 as well as Figure 8 As shown. The clamping block assembly 50 is installed onto the component to be disassembled (oil filter). When the clamping blocks are released, the first clamping block 51 and the second clamping block 52, under the pulling force of the first elastic element 53, clamp the component to be disassembled. At this time, the disassembly / reassembly tool... Figure 5 as well as Figure 6 As shown, when the wrench is installed in the wrench hole 11 and rotated counterclockwise (rotating in the first direction), the first pawl 610 engages with the ratchet 12, and the rotating part 10, base 20, two connecting rods 40, and clamping block assembly 50 become a single unit, causing the part to be disassembled to rotate counterclockwise and be removed from the workpiece (automobile). If the wrench is rotated clockwise (rotating in the second direction), the rotating part 10 rotates normally.

[0049] When it is necessary to install the part to be disassembled, the first clamping block 51 and the second clamping block 52 are disengaged, and the part to be disassembled is installed onto the clamping block assembly 50. The clamping blocks are then released, and the first clamping block 51 and the second clamping block 52 clamp the part to be disassembled under the pulling force of the first elastic element 53. The lever 30 is then turned to engage the second pawl 611 with the ratchet 12, and the first pawl 610 is disengaged from the ratchet 12. At this time, the wrench is installed into the wrench hole 11, and the wrench is rotated clockwise (rotating in the second direction). The second pawl 611 and the ratchet 12 are locked together, and the rotating part 10, the base 20, the two connecting rods 40, and the clamping block assembly 50 become a single unit, causing the part to be disassembled to rotate clockwise, thus installing the part onto the workpiece (automobile). If the wrench is rotated counterclockwise (rotating in the first direction), the rotating part 10 rotates normally.

[0050] The disassembly and assembly tool of this utility model has multiple clamping blocks that are movably connected to switch between a retracted state and an open state, allowing the tool to be used with parts of different sizes to be disassembled and assembled. When the dial 30 abuts against the first pawl 610, causing the first pawl 610 to engage with the ratchet 12, and the rotating member 10 rotates around the first direction under external force, the first pawl 610 and the ratchet 12 lock together, and the rotating member 10 drives the multiple clamping blocks and the parts to be disassembled and assembled held by the multiple clamping blocks to rotate around the first direction. When the dial 30 abuts against the second pawl 611, causing the second pawl 611 to engage with the ratchet 12, and the rotating member 10 rotates around the second direction opposite to the first direction under external force, the second pawl 611 and the ratchet 12 lock together, and the rotating member 10 drives the multiple clamping blocks and the parts to be disassembled and assembled held by the multiple clamping blocks to rotate around the first direction. Multiple clamping blocks and the component to be disassembled held by the clamping blocks rotate around a second direction; by rotating the dial 30, the disassembly and assembly tool can drive the component to be disassembled to rotate forward and backward, realizing the disassembly and assembly of the component, which is convenient to use; the two ends of the first elastic element 53 are respectively fixedly connected to the two clamping blocks, so that the multiple clamping blocks automatically clamp; the first clamping part 510 and the second clamping part 520 are provided with anti-slip textures on the side facing the clamping space, which can prevent the disassembly and assembly tool from slipping between itself and the component to be disassembled during use; the rotating part 10 is also provided with a wrench hole 11, which is located outside the base 20, and the wrench hole 11 is used to install a wrench, which is convenient to use; the overall structure of the disassembly and assembly tool is simple and small in size, making it easy to carry and use.

[0051] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
