[0027] Embodiment 1

[0028] Reference Figures 1 to 4 As shown, the utility model discloses a fixing device, which can be used to compress a filter installed in a clean equipment, so that the filter can be stably assembled in the clean equipment and is easy to disassemble. The fixing device includes a housing 1.

The mounting seat 30 is arranged inside the housing 1, the elastic member 33 is arranged on the mounting seat 30, and the stopper 32 is arranged at the movable end of the elastic member 33, so that the stopper 32 can move under the drive of the elastic member 33. In addition, the stopper 32 is also in active contact with the transmission wheel 31, and the elastic deformation direction of the elastic member 33 is in the same direction as the radial direction of the transmission wheel 31.

[0032] It should be explained that the fixing device has an initial state, a compressed state and a loosened state: in the initial state, refer to Figure 3 As shown, the transmission wheel 31 is in contact with the limiting member 32, and at this time, the pressing member 20 is not in contact with the filter to be fixed;

[0033] When the filter to be fixed needs to be pressed and fixed, Figure 4 From the perspective of the embodiment, the pressing member 20 is moved until the pressing member 20 presses and fixes the filter to be fixed. At this time, the pressing member 20 drives the transmission wheel 31 to rotate. After pressing, the elastic member 33 connected to the limiting member 32 applies a force to the limiting member 32, so that the limiting member 32 abuts against the transmission wheel 31, thereby limiting the position of the transmission wheel 31. At this time, the fixing device is in a pressed state.

[0034] When the filter needs to be loosened, refer to Figure 4 as well as Figure 5As shown, the limiting member 32 is pressed downward to separate the limiting member 32 from the transmission wheel 31. At this time, the pressing member 20 can move freely. The pressing member 20 is separated from the filter. Figure 5 As shown, the fixing device is in a released state.

[0035] It can be known that the fixing device to be protected by the utility model is provided with a shell, a clamping unit and a transmission unit, wherein the clamping unit includes a clamping member and a connecting rod, the clamping unit can clamp or loosen the filter to be fixed, the transmission unit includes a transmission wheel, a limiter and an elastic member, the transmission wheel is connected to the clamping member through a connecting rod, the limiter and the transmission wheel are movably connected, when the filter is fixed, the fixing device is in a clamping state, the clamping member abuts against the filter to be fixed, and the limiter abuts against the transmission wheel, by adjusting the position of the limiter, the limiter moves in a direction away from the transmission wheel until the limiter is separated from the transmission wheel, so that the transmission wheel can rotate freely, at this time, the clamping member can be separated from the filter, so as to facilitate the removal of the filter. The utility model is small and light, so it is easy to be installed in the gap between the filter and the box body, the device can facilitate the installation and removal of the filter, and reduce the time required for installation and removal, and only a small operating stroke is required to achieve installation and removal, thereby effectively improving the installation and replacement efficiency of the filter.

[0037] As a preferred embodiment, the transmission unit also includes a connecting disk 34, which is coaxially arranged with the transmission wheel 31, and the connecting disk 34 and the transmission wheel 31 can rotate synchronously, the connecting rod 21 is connected to the connecting disk 34, and the connecting rod 21 is connected to the transmission wheel 31 through the connecting disk 34, so that when the connecting rod 21 moves, it can drive the connecting disk 34 and the transmission wheel 31 to move synchronously.

[0038] In detail, in order to facilitate the adjustment of the position of the clamping member 20, the connecting rod 21 includes a connecting portion 210 and a bending portion 211, one end of the connecting portion 210 is connected to the connecting plate 34, and the other end of the connecting portion 210 is connected to the bending portion 211, one end of the bending portion 211 is connected to the connecting portion 210, and the other end is connected to the clamping member 20.

[0041] Furthermore, a mounting plate 301 is provided on the support base plate, and the mounting plate 301 is perpendicular to the support base plate. Three mounting plates 301 are provided and are sequentially connected to form a storage space, and the limiting member 32 is accommodated in the storage space surrounded by multiple mounting plates 301.

[0042] As a preferred embodiment, the mounting seat 30 and the limiting member are arranged below the transmission wheel 31. In this way, the movement of the limiting member 32 can be limited, so that the limiting member 32 always moves along the height direction, and the limiting member 32 is prevented from deflecting.

[0043] As a preferred embodiment, the mounting seat 30 is also provided with a baffle 302, and the baffle 302 is horizontally extended along the top of the mounting plate 301, so that the baffle 302 can limit the limit member 32 in the height direction to prevent the limit member 32 from moving to the outside of the storage space.

[0044] As a preferred embodiment, in order to facilitate the operation of the operator and to facilitate the adjustment of the position of the limiter 32, a connecting column 320 is provided on the limiter 32. The housing 1 is provided with a through hole for accommodating the connecting column 320, and the connecting column 320 is penetrated through the through hole and protrudes from the surface of the housing 1.

[0047] During operation, after the filter to be fixed is moved to the required position, the pressing member 20 is pushed toward the filter until the filter is pressed. At this time, the limiter 32 prevents the ratchet from rotating, and the filter is installed and fixed. When the filter needs to be removed, the limiter 32 is pressed downward, and the limiter 32 is separated from the ratchet. At this time, the pressing member 20 can be moved in the opposite direction to a suitable position, so that the pressing member 20 is separated from the filter, and the filter can be removed smoothly.
