[0054] Example 1

[0055] This invention provides a filter-based clamping mechanism, such as... Figures 1-4 As shown, it includes:

[0056] Filter frame 1, used to house filter body 2;

[0057] Multiple sets of clamping assemblies are used to lock the filter body 2 within the filter frame 1. Preferably, four sets of clamping assemblies are provided, located at the four corners of the filter body 2. The clamping assemblies include:

[0058] The first pressure plate 3 is used to abut against the filter body 2;

[0059] A second pressure plate 4 is provided on the outside of the first pressure plate 3, and the filter frame 1 is provided with a limiting flange 9 for abutting against the second pressure plate 4;

[0060] The clamping bolt 5 is threadedly engaged with the second pressure plate 4. Preferably, a nut 6 that is threadedly connected to the clamping bolt 5 is welded and fixed on the second pressure plate 4. The clamping bolt 5 passes through the second pressure plate 4 and is rotatably connected to the first pressure plate 3, which can be rotatably connected by a bearing.

[0061] When in use, the first pressure plate 3 is brought into contact with the filter body 2, and then the clamping bolt 5 is rotated. The clamping bolt 5 drives the second pressure plate 4 to move outward through the nut 6 until it is pressed against the limiting folded edge 9, thereby pressing and fixing the filter body 2. The structure is simple, stable and quick to install, and has good practical effect.

[0062] The filtering frame 1 includes:

[0063] Frame;

[0064] The first limiting plate 7, which is located on the frame and opposite to the pressure block assembly, can be fixed by welding and is used to limit the filter body 2 in conjunction with the pressure block assembly.

[0065] The second limiting plate 8, located on the inner wall of the frame, can be fixed by welding and is used to limit the position of the filter body 2.

[0066] Example 2

[0067] This embodiment is based on embodiment 1, such as... Figures 5-8 As shown, it also includes a connecting component for connecting all the pressing block components, the connecting component comprising:

[0068] Mounting plate 10;

[0069] Multiple pins that are circumferentially spaced and rotatably mounted on the mounting plate 10 can be connected by bearings. The number of pins is equal to the number of pressure block assemblies and corresponds one-to-one.

[0070] A sleeve 11 is rotatably mounted on each pin. An installation rod 15 is movably connected to the sleeve 11 along its length. Preferably, the installation rod 15 is movably inserted into the sleeve 11. The end of the installation rod 15 away from the sleeve 11 is rotatably connected to the clamping bolt 5, preferably through a bearing. A first spring 13 is provided between the installation rod 15 and the sleeve 11. The force of the first spring 13 on the installation rod 15 is directed toward the clamping bolt 5. Preferably, the first spring 13 is sleeved on the installation rod 15. The two ends of the first spring 13 abut against the protrusions provided on the end of the sleeve 11 and the installation rod 15, respectively.

[0071] A rotating sleeve 12 is rotatably mounted on the sleeve 11. A worm 14 is slidably connected to the rotating sleeve 12 along its length. When the rotating sleeve 12 rotates, it can drive the worm 14 to rotate. The worm 14 can slide along the length of the rotating sleeve 12. Preferably, the worm 14 is movably inserted into the rotating sleeve 12. A protrusion is provided on the worm 14 along its length. A groove is provided in the rotating sleeve 12 that is slidably connected to the protrusion. A worm wheel 19 that meshes with the worm 14 is fixed on the clamping bolt 5. It can be fixed by welding.

[0072] A second bevel gear 16 is fixed to one end of the rotating sleeve 12 near the pin shaft. A first bevel gear 17 that meshes with the second bevel gear 16 is coaxially fixed on the pin shaft. The first bevel gear 17 can be fixed by welding.

[0073] Transmission component 18 is used to drive all pins to rotate synchronously.

[0074] In use, the sleeve 11 is rotatably connected to the pin shaft. The sleeve 11 can be manually rotated to adjust its angle, thereby adjusting the position of the pressure block assembly through the mounting rod 15. It can be pressed in different positions. The mounting rod 15 is movably connected to the sleeve 11, and a spring is provided between the two. It can adapt to the pressing and fixing of filter bodies 2 of different shapes and sizes, meet more usage needs, and improve adaptability.

[0075] Understandably, after the pressure block assembly is placed in the clamping position, the transmission component 18 drives all the pins to rotate synchronously. The pins drive the first bevel gear 17 to rotate, and the first bevel gear 17 drives the rotating sleeve 12 to rotate through the second bevel gear 16. It should be explained that the first bevel gear 17 is coaxial with the pin. When the sleeve 11 rotates around the pin, the rotating sleeve 12 and the second bevel gear 16 on it also rotate around the pin. Since the first bevel gear 17 is coaxial with the pin, even if the sleeve 11 rotates, the second bevel gear 16 remains engaged with the first bevel gear 17. The rotating sleeve 12 drives the worm gear 14 to rotate, and the worm gear 14 drives the threaded rod to rotate through the worm wheel 19. The threaded rod drives the second pressure block to move and abut against the limiting flange 9, thereby clamping and fixing the filter body 2. All pressure block assemblies can be operated simultaneously for clamping, which is convenient and practical and improves work efficiency.

[0076] The transmission component 18 includes:

[0077] The mounting shaft, which is rotatably mounted on the mounting plate 10, can be rotatably mounted via bearings, and a handle can also be welded onto the mounting shaft. The axis of the mounting shaft passes through the center of all the pins.

[0078] The driving spur gear, which is coaxially fixed to the mounting shaft, can be fixed by welding.

[0079] Driven spur gears fixed on a pin shaft along the same axis can be fixed by welding, and all driven spur gears mesh with the driving spur gears respectively;

[0080] It is understandable that by manually rotating the mounting shaft, the mounting shaft drives the driving spur gear to rotate, and the driving spur gear drives all the pins to rotate synchronously through the driven spur gear. Of course, the transmission component 18 can also be a belt and pulley or a chain and sprocket, etc., without too many restrictions.

[0081] Example 3

[0082] This embodiment is based on embodiment 2, such as Figures 9-11 As shown, it also includes a shock-absorbing component for buffering and damping the filter body 2. The shock-absorbing component includes:

[0083] A support plate 20 is provided on the side of the second limiting plate 8 near the filter body 2 to support the filter body 2;

[0084] Multiple arc-shaped elastic plates 21 are disposed between the support plate 20 and the second limiting plate 8. The arc-shaped elastic plates 21 are arched, and their tops are in contact with the lower surface of the support plate 20. They are used to provide elastic support for the support plate 20, thereby enabling buffering and shock absorption.

[0085] Multiple vertical telescopic rods 24 are fixedly connected between the support plate 20 and the second limiting plate 8, and can be fixed by welding. The telescopic rods 24 include a sleeve 30 and a movable rod 31 that is movably inserted into the sleeve 30.

[0086] In this embodiment, the shock absorption component further includes:

[0087] Rotating the shaft 23 located below the arc-shaped elastic plate 21, the shaft 23 can be installed through bearings and bearing seats, and the crank handles can be welded and fixed at both ends of the shaft 23. The shaft 23 is provided with multiple sets of bidirectional screw segments, and each arc-shaped elastic plate 21 is matched with a set of bidirectional screw segments.

[0088] The two threaded sleeves 22 are hinged to both ends of the arc-shaped elastic plate 21. The two threaded sleeves 22 are respectively threadedly connected to the two threaded sections of a set of bidirectional screw segments. The threaded sleeves 22 are slidably connected to the second limiting plate 8. Preferably, a slider is fixed on the threaded sleeve 22, and a sliding groove is provided on the second limiting plate 8 for the slider to slide.

[0089] The rotating shaft 23 can be manually rotated, and the bidirectional lead screw section on the rotating shaft 23 drives the two internal threaded sleeves 22 to move closer or further apart. The internal threaded sleeves 22 drive the arc-shaped elastic plate 21 to move, changing its curvature and elastic potential energy, thereby achieving the effect of adjusting buffering and shock absorption.

[0090] Furthermore, at least one set of support rods is provided on the second limiting plate 8 below each arc-shaped elastic plate 21. Each set of support rods includes two support rods 25. The two support rods 25 are V-shaped and their bottom ends are hinged to the second limiting plate 8. Support wheels are rotatably installed on the top ends of the two support rods 25. The support wheels are in contact with the arc-shaped elastic plate 21. A second spring 26 is connected between the two support rods 25. The second spring 26 is a tension spring. When the arc-shaped elastic plate 21 is deformed by compression, the two support rods 25 separate, and the tension spring generates tension on the two support rods 25. The support wheels support the arc-shaped elastic plate 21, which again plays a role in buffering and shock absorption.

[0091] Furthermore, the telescopic rod 24 also includes a housing 28 and an airbag 29. The housing 28 is fixed to one end of the sleeve 30 inserted into the movable rod 31 and can be welded. The housing 28 has a through hole for the movable rod 31 to pass through. The housing 28 has an annular airbag 29 inside, which is sleeved on the movable rod 31. The other end of the sleeve 30 is connected to a connecting pipe 27, which is connected to the airbag 29.

[0092] When the movable rod 31 moves downward, it forces the air in the sleeve 30 into the airbag 29. The volume of the airbag 29 increases, and the pressure between it and the movable rod 31 increases, thereby increasing the friction and creating resistance to the movement of the movable rod 31. This provides a buffering and shock-absorbing effect and improves the shock absorption efficiency.

[0093] In summary, this invention provides a filter-based clamping mechanism, the working principle of which is as follows:

[0094] Place the filter body 2 into the filter frame 1, then rotate the sleeve 11 to adjust the pressure block assembly to the clamping position. Manually rotate the mounting shaft, which drives the driving spur gear. The driving spur gear, through the driven spur gear, drives all the pins to rotate synchronously. The pins drive the first bevel gear 17 to rotate, and the first bevel gear 17, through the second bevel gear 16, drives the rotating sleeve 12 to rotate. It should be noted that the first bevel gear 17 is coaxial with the pins. When the sleeve 11 rotates around the pins, the rotating sleeve 12 and the second bevel gear 16 on it also rotate around the pins. When the shaft rotates, since the first bevel gear 17 is coaxial with the pin shaft, even if the sleeve 11 rotates, the second bevel gear 16 remains engaged with the first bevel gear 17. The rotating sleeve 12 drives the worm gear 14 to rotate, and the worm gear 14 drives the threaded rod to rotate through the worm wheel 19. The threaded rod drives the second pressure block to move and abut against the limiting flange 9, thereby pressing and fixing the filter body 2. All pressure block components can be operated simultaneously for pressing, which is convenient and practical and improves work efficiency. The shock absorption component can buffer and dampen the filter body 2, protecting the filter body 2.
