[0033] Example 1

[0034] Reference Figures 1-5 The first embodiment of the present invention provides a brake piston removal device. The device includes an upper fixing component 100, a switching component 101, and a rotating fixing component 102 located outside the switching component 101. The switching component 101 is covered with a brake cylinder 102a. The switching component 101 includes a first rotating cylinder 101c located inside the brake cylinder 102a.

[0035] Specifically, a pressing cylinder 101a is sleeved on the inner wall of the first rotating cylinder 101c.

[0036] In this mechanism design, the components are arranged as follows: the pressing cylinder 101a is located at the innermost layer, and a first rotating cylinder 101c is nested around it; the first rotating cylinder 101c is further placed inside the brake cylinder 102a, forming a nested structure of pressing cylinder 101a—first rotating cylinder 101c—brake cylinder 102a. The first rotating cylinder 101c and the brake cylinder 102a are fixedly connected, meaning they maintain a rigid fit and there is no relative rotation. When the brake cylinder 102a is driven and begins to rotate, it directly and effectively transmits the rotational motion to the first rotating cylinder 101c through its fixed connection with the first rotating cylinder 101c, causing the first rotating cylinder 101c to rotate synchronously with the brake cylinder 102a. This structural design ensures effective motion transmission and stable overall operation.

[0037] Specifically, a slider 101b is fixedly connected to the outer wall of the pressing cylinder 101a, and an annular groove 101e is opened inside the second rotating cylinder 201a. The slider 101b slides in the annular groove 101e, and a handle is fixedly connected to one end of the outer wall of the pressing cylinder 101a.

[0038] Five sets of sliders 101b are evenly arranged on the outer wall of the pressing cylinder 101a. This design of multiple sets of sliders 101b ingeniously enhances the stability of the pressing cylinder 101a during movement. Specifically, these five sliders 101b are closely attached to and fixed on the outer wall, forming a stable contact and linkage relationship with the corresponding structure on the inner wall of the second rotating cylinder 201a. When the pressing cylinder 101a is subjected to a force and moves downward, the second rotating cylinder 201a can be driven to rotate synchronously and smoothly through these five sliders 101b.

[0039] In addition, a sturdy handle is fitted to one end of the pressing cylinder 101a, which the operator can control by directly pressing the handle to move the pressing cylinder 101a up and down in the vertical direction.

[0040] Furthermore, the annular groove 101e is composed of five vertical grooves and five V-shapes, with the starting height of each V-shape of the annular groove 101e being higher than the ending height.

[0041] The slider 101b is cleverly embedded in the annular groove 101e inside the second rotating cylinder 201a, allowing it to slide along the groove. When an external force is applied to press down on the pressing cylinder 101a, the slider 101b, which is fixed to the pressing cylinder, also moves downward along the longitudinal axis. The slider 101b first slides in the vertical section of the annular groove 101e. At this time, due to the unique design of the annular groove 101e, its shape contains a series of V-shaped structures, with the starting end of each V-shape being higher than the ending end, which means that the concave part at the bottom of the V-shape faces the higher side.

[0042] When the slider 101b slides down to the entrance of the V-shaped structure, it will naturally be guided to the shorter side of the V-shape. This design ensures that the slider 101b has a clear path selection each time it falls. Although the pressing cylinder 101a itself can only make simple vertical displacement, through the cooperation of the slider 101b and the special channel, each time the slider falls to the bottom of the V-shaped groove and then slides up, it will drive the second rotating cylinder 201a to rotate.

[0043] In summary, when a complete pressing operation is completed, the slider 101b will slide down to the short side of the V-shape in the annular groove 101e, slide up with the V-shaped structure, and re-enter the vertical groove. At the same time, the second rotating cylinder 201a will rotate at a certain angle accordingly.

[0044] Furthermore, a first handle 102c is fixedly connected to one side of the brake cylinder 102a, and a first turntable 102d is rotatably connected to the outer wall of the brake cylinder 102a. A groove is opened inside the first turntable 102d, and a first gear 102e is installed in the groove. The first gear 102e is fixedly connected to the brake cylinder 102a.

[0045] The first handle 102c is located at one end of the brake cylinder 102a. The operator can directly control the rotation of the brake cylinder 102a by rotating the first handle 102c. It is worth mentioning that the brake cylinder 102a and the first turntable 102d are rotatably connected, which means that the first turntable 102d does not rotate during the rotation of the brake cylinder 102a, and there is no relative displacement between the two in the vertical direction.

[0046] Looking further, the first gear 102e maintains a fixed connection with the brake cylinder 102a, while simultaneously achieving a rotatable connection with the first turntable 102d. Therefore, when the brake cylinder 102a rotates under the drive of the first handle 102c, the first gear 102e will also rotate synchronously due to its rigid connection with the first gear 102e. In summary, by operating the first handle 102c, torque transmission from the brake cylinder 102a to the first gear 102e can be achieved, while during this process, the first turntable 102d remains stationary but allows the brake cylinder 102a to rotate freely above it.

[0047] Preferably, the first gear 102e meshes with a set of second gears 102f, and a first nut rod 102g is fixedly connected to the middle of the second gear 102f. The bottom of the first nut rod 102g is provided with a threaded hole.

[0048] It should be noted that the first gear 102e and the second gear 102f form a meshing transmission relationship. Once the first gear 102e starts to rotate, due to the meshing characteristics between gears, it will immediately drive the second gear 102f, which meshes with it, to rotate synchronously. The middle part of the second gear 102f is fixedly connected to the first nut rod 102g. Therefore, any rotation of the second gear 102f will be transmitted to the first nut rod 102g, causing it to rotate together. The bottom of the first nut rod 102g is specially designed with a threaded hole. When it rotates under the action of the second gear 102f, this threaded hole can be tightly engaged with the matching screw.

[0049] In short, when the first gear 102e rotates, it drives the second gear 102f and the first nut rod 102g to rotate in sequence through the gear transmission chain. Ultimately, the first nut rod 102g moves relative to the matching screw through the threaded hole at its bottom, thereby achieving the purpose of tightening or adjusting.

[0050] Example 2

[0051] Reference Figures 1-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a lower pull-out component 200 is provided, which is located below the upper fixing component 100. The lower pull-out component 200 includes an adjustment component 201 sleeved on the outer wall of the switching component 101, a rotating component 202 installed on the outside of the adjustment component 201, and a second rotating cylinder 201a sleeved on the switching component 101. The second rotating cylinder 201a has a corresponding second groove 201b.

[0052] Furthermore, the second rotating cylinder 201a is rotatably connected to the first rotating cylinder 101c, and a base 201e is fixedly connected to the bottom of the second rotating cylinder 201a. An annular groove 101e is provided inside the second rotating cylinder 201a.

[0053] The first rotating cylinder 101c and the brake cylinder 102a are fixedly connected, meaning they do not rotate relative to each other as a whole. However, the second rotating cylinder 201a is rotatably connected to the first rotating cylinder 101c, so the second rotating cylinder 201a can rotate independently without affecting the first rotating cylinder 101c and the brake cylinder 102a.

[0054] A base 201e is fixed to the bottom of the second rotating cylinder 201a. The important function of the base 201e is to provide a limit, ensuring that objects placed on the second rotating cylinder 201a will not slip or fall off due to the rotation of the second rotating cylinder 201a. At the same time, the second rotating cylinder 201a adopts a double-layer structure design: its outer layer is made of silicone material, which is designed to increase the friction of the contact surface to ensure that objects placed on it remain stable during rotation and are not easy to slip off; while the inner layer is made of rigid material, ensuring that the second rotating cylinder 201a can effectively transmit power when rotating, driving other objects connected to it to rotate as well.

[0055] Furthermore, the rotating assembly 202 includes a second turntable 202d sleeved outside the second rotating cylinder 201a. A groove is opened inside the second turntable 202d, and a third gear 202e is installed in the groove. The third gear 202e is rotatably connected to the second turntable 202d. The third gear 202e meshes with a set of fourth gears 202f. A second nut rod 202g is fixedly connected to the middle of the fourth gear 202f. A threaded hole is opened at the bottom of the second nut rod 202g.

[0056] The second turntable 202d is designed to be mounted outside the second rotating cylinder 201a with a silicone layer. Due to the frictional resistance provided by the silicone layer, the second turntable 202d can remain relatively stationary without any additional external force, and will not undergo axial or radial displacement.

[0057] Inside the second turntable 202d, a third gear 202e is installed. Although the third gear 202e rotates, it does not directly cause the second turntable 202d to move accordingly. Importantly, the third gear 202e forms a meshing transmission relationship with a set of fourth gears 202f, which means that when the third gear 202e rotates, it can effectively drive the fourth gear 202f to rotate synchronously.

[0058] A second nut rod 202g is fixedly connected to the middle of the fourth gear 202f. In this way, any rotation of the fourth gear 202f will be converted into the rotation of the second nut rod 202g. The bottom of the second nut rod 202g is specially machined with a threaded hole. Therefore, when the second nut rod 202g rotates, the threaded hole at its bottom can form a rotational lock with the corresponding screw. In this way, the motion conversion from gear transmission to threaded fastener is completed.

[0059] Furthermore, the inner wall of the second turntable 202d is provided with two sets of symmetrical grooves. One set of grooves is fixedly connected to the first telescopic threaded block 202h, and the other set of grooves is fixedly connected to the second telescopic block 202k. The inner wall of the third gear 202e is provided with threads, and a set of symmetrical second telescopic threaded blocks 202i is slidably connected in the threads. The second telescopic threaded blocks 202i slide in the slide rail 202j fixedly connected to the inner wall of the second turntable 202d.

[0060] The inner wall of the second turntable 202d features two sets of symmetrically arranged grooves. One groove houses a first telescopic threaded block 202h, while the other groove houses a second telescopic block 202k. Both types of telescopic blocks have threaded blocks at their front ends, allowing the first telescopic threaded block 202h and the second telescopic block 202k to move flexibly within the grooves on the inner wall of the second turntable 202d.

[0061] Meanwhile, the inner wall of the third gear 202e has a threaded track. Within this threaded area, a pair of symmetrically arranged second telescopic threaded blocks 202i are slidably connected. The movement trajectory of these second telescopic threaded blocks 202i is subject to dual constraints: on the one hand, they can slide up and down within the slide rail 202j fixed to the inner wall of the second turntable 202d; on the other hand, they must follow the guidance of the inner thread of the third gear 202e to move.

[0062] Therefore, when the second telescopic threaded blocks 202i move vertically within the slide rail 202j, they slide along the spiral thread trajectory on the inner wall of the third gear 202e, thereby driving the third gear 202e to rotate around its own axis. This design ensures the accuracy and stability of motion conversion, effectively converting linear motion into rotational motion.

[0063] Furthermore, the second telescopic block 202k, the first telescopic threaded block 202h, and the second telescopic threaded block 202i are 72 degrees apart.

[0064] The three components—the second telescopic block 202k, the first telescopic threaded block 202h, and the second telescopic threaded block 202i—are arranged at 72-degree intervals. When the pressing cylinder 101a is operated, a slider 101b is fixedly connected to its outer wall. This slider 101b slides within a specially designed annular groove 101e inside the second rotating cylinder 201a. This annular groove 101e has a unique structure composed of five alternating vertical groove segments and five V-shaped groove segments.

[0065] When pressing force is applied to the pressing cylinder 101a, the slider 101b slides and advances within the annular groove 101e. Due to the special design of the groove, each complete slide—that is, the process of the pressing cylinder descending and then resetting—drives the second rotating cylinder 201a to rotate 72 degrees. This rotation angle precisely ensures that whenever the second rotating cylinder 201a rotates to its final position, the telescopic blocks at the next 72-degree position (first the second telescopic block 202k, then the first telescopic threaded block 202h, followed by the second telescopic threaded block 202i) can sequentially align precisely with the second groove 201b inside the second rotating cylinder 201a, achieving effective engagement. This design achieves precise coupling and orderly switching between the pressing action and the rotational motion.

[0066] Specifically, a rotating column 202a is rotatably connected inside the pressing cylinder 101a. A second handle 202b is fixedly connected to one side of the rotating column 202a. A base 201e is rotatably connected to the bottom of the rotating column 202a. A threaded sleeve 202l is fixedly connected to one end of the rotating column 202a. A groove corresponding to the second groove 201b is opened on the threaded sleeve 202l. A push block 202c slides in the groove. The inner side of the push block 202c is inclined.

[0067] When the operator applies power to the second handle 202b, it directly drives the rotating column 202a to rotate. Although the rotating column 202a is rotatably connected to the inside of the pressing cylinder 101a, its rotation does not cause any change in the movement of the pressing cylinder 101a itself. Similarly, the bottom of the rotating column 202a is also rotatably connected to the base 201e, so even if the rotating column 202a moves, it will not affect the position of the second rotating cylinder 201a connected to the base 201e.

[0068] A threaded sleeve 202l is fixedly connected to one end of the rotating column 202a. When the rotating column 202a rotates, the threaded sleeve 202l will rotate accordingly. The surface of the threaded sleeve 202l has a groove corresponding to the second groove 201b inside the second rotating cylinder 201a. When the groove on the threaded sleeve 202l is exactly aligned with the second groove 201b, the second telescopic block 202k will be embedded in the two grooves.

[0069] In this mechanical structure design, the opening angle of the second groove 201b is specifically set to 72 degrees. Correspondingly, the angle of the second telescopic threaded block 202i is also designed to be 72 degrees. This precise matching is to ensure that the second telescopic threaded block 202i can make maximum contact with the threaded sleeve 202l during the rotation of the threaded sleeve 202l, thereby enhancing the mechanical interaction between the two and improving working efficiency and stability.

[0070] In addition, the 72-degree slot angle has another important design consideration, which is to ensure that when the second rotating cylinder 201a rotates to any 72-degree division, the second slot 201b can only accommodate one object or be completely empty. This can effectively avoid jamming or conflict caused by multiple components in the same slot, and at the same time ensure that the action of each stage during the rotation can be executed accurately, so as to achieve orderly and smooth operation of the device.

[0071] The threaded sleeve 202l also contains a sliding pusher 202c. When the second telescopic block 202k slides into the second groove 201b, the pusher 202c is forced to move towards the inner wall of the threaded sleeve 202l and protrude. The inner surface of the pusher 202c is designed as a slope. In actual operation, when the pressing cylinder 101a is pressed, the pressing action acts on the slope on the inner side of the pusher 202c, thereby pushing the second telescopic block 202k in the upper groove of the threaded sleeve 202l outward. At the same time, the pressing of the pressing cylinder 101a also drives the second rotating cylinder 201a to rotate, causing the previously aligned second groove 201b to gradually disengage from the mating position with the second telescopic block 202k. At this time, the second telescopic block 202k is squeezed and retracts. This ingenious mechanical linkage design ensures coordinated operation between the components and realizes precise control and function switching of the entire device.

[0072] Example 3

[0073] Referring to Figures 1-6, the third embodiment of the present invention includes an upper fixing component 100, a switching component 101, and a rotating fixing component 102 located outside the switching component 101. The switching component 101 is fitted with a brake cylinder 102a. The switching component 101 includes a first rotating cylinder 101c located inside the brake cylinder 102a. A lower pull-out component 200 is located below the upper fixing component 100. The lower pull-out component 200 includes an adjusting component 201 fitted on the outer wall of the switching component 101. The rotating component 202 is mounted on the outside of the adjusting component 201. The switching component 101 is fitted with a second rotating cylinder 201a. The second rotating cylinder 201a has opposing second grooves 201b.

[0074] In use, rotating the first handle 102c rotates the brake cylinder 102a, which in turn rotates the first gear 102e, causing the first nut rod 102g to engage with the brake housing screw. Moving the handle on the pressing cylinder 101a causes it to move downwards, rotating the second rotating cylinder 201a 72 degrees. At this point, the second groove 201b on the second rotating cylinder 201a coincides with the groove on the threaded sleeve 202l, and the second groove 201b aligns with the second telescopic block 202k. The second telescopic block 202k extends into the second groove 201b and the groove on the threaded sleeve 202l. Rotating the second handle 202b then rotates the rotating column 202a, which in turn rotates the threaded sleeve 202l. The second telescopic block 202k rotates, which in turn rotates the second turntable 202d. The second turntable 202d is adjusted to a suitable angle with the piston bolt. After adjustment, the pressing cylinder 101a is pressed. At this time, the bottom of the pressing cylinder 101a enters the space between the threaded sleeve 202l and the rotating column 202a, pressing the inclined surface of the push block 202c. This causes the push block 202c to press the second telescopic block 202k and push it out of the grooves on the second groove 201b and the threaded sleeve 202l. The pressing of the pressing cylinder 101a causes the second rotating cylinder 201a to rotate. Therefore, the second groove 201b and the groove on the threaded sleeve 202l do not coincide. At this time, the second groove 201b and the first telescopic block 202k... When the threaded block 202h overlaps, rotating the second handle 202b causes the first threaded block 202h to screw onto the threaded sleeve 202l. Therefore, the rotation of the rotating column 202a causes the second turntable 202d to move up and down. After moving the second turntable 202d to the appropriate position, pressing the pressing cylinder 101a causes the second rotating cylinder 201a to rotate, causing the second groove 201b to deviate from the first telescopic threaded block 202h. When the second groove 201b presses against the first telescopic threaded block 202h, due to the inclined edge of the first telescopic threaded block 202h, it is pressed until the second groove 201b overlaps with the second telescopic threaded block 202i, and the second telescopic block 202i screws onto the threaded sleeve 202l. Rotating the second handle 202b causes the threaded sleeve 202l to rotate. The rotation of the threaded sleeve 202l causes the second telescopic threaded block 202i to move vertically and slide on the thread inside the third gear 202e, thus rotating the third gear 202e. Through the rotation of the third gear 202e, the second nut rod 202g is screwed into the piston screw. At this point, pressing the pressing cylinder 101a four times and rotating the second handle 202b again causes the first telescopic threaded block 202h to screw into the threaded sleeve 202l, bringing the first turntable 102d and the second turntable 202d closer together, allowing the piston to be pulled out. This design saves manpower, ensures safety, avoids the risk of injury from falling objects, and facilitates disassembly and assembly.This saves maintenance time and makes the maintenance process more efficient. After being pulled out, the device can be restored to its initial position by reversing the operation, and the same applies to the next use.
