Description

Technical Field

[0001] The utility model relates to the technical field of air suspension centrifugal fans, in particular to a control panel protection structure for air suspension centrifugal fans. Background Art

[0002] The air-suspended centrifugal fan is an integrated machine of a permanent magnet motor and a centrifugal fan, sharing a common shaft. The fan has a small impeller and a high speed to ensure high wind pressure and sufficient air volume. It is based on dynamic pressure air bearing technology and permanent magnet direct-drive motor technology. It uses air-suspended bearings to make the fan shaft self-suspended when rotating at high speed. The air-suspended centrifugal blower is different from the traditional Roots blower. Compared with the Roots blower, the air-suspended centrifugal blower reduces the friction loss of equipment operation and saves electricity. There is no mechanical wear, only wind friction loss, and the wind friction power consumption is within 200W. Compared with the magnetic suspension fan, the air suspension fan has no magnetic field circuit, is not afraid of emergency stop and power failure, and is more convenient to maintain.

[0003] The above-mentioned prior art solutions have the following defects: the control panel of the existing air suspension centrifugal fan outer chassis does not have a good protective structure, and some even do not have a protective cover, making it impossible to protect the display screen and control buttons. Utility Model Content

[0004] The utility model aims to provide a control panel protection structure for an air suspension centrifugal fan.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A control panel protection structure for an air-suspended centrifugal fan comprises a box body, a mounting groove is reserved on the outer side of the box body, a control panel body is fixedly connected to the inside of the mounting groove, a first connecting block is fixedly connected to the outer side of the box body, a protective cover is provided on the outer side of the mounting groove, a second connecting block is fixedly connected to the outer side of the protective cover, a card slot is reserved on the outer side of the protective cover, and a sealing plate is fixedly connected to the inner side of the protective cover.

[0007] By adopting the above technical solution, a mounting groove is added on the outside of the box body, and a control panel is added inside the mounting groove. A protective cover that can be flipped open can be added on the outside of the control panel to protect the control panel.

[0008] Furthermore, a fixing block is fixedly connected to the outer side of the box body and located on the outer side of the protective cover, a cavity is opened inside the fixing block, and a clamping block, a connecting rod and a spring are arranged inside the cavity.

[0009] By adopting the above technical solution and adding a spring clamping structure, the protective cover can be installed by clamping, which is convenient for operation.

[0010] Furthermore, the first connecting block and the second connecting block are movably connected via a torsion spring.

[0011] By adopting the above technical solution, the protective cover can be automatically opened by torsion spring. Once the connecting rod is opened, the protective cover will be directly opened without limit, which makes it more convenient to open. At the same time, the control panel can be operated at any time, which is convenient to use.

[0012] Furthermore, the sealing plate is snap-connected to the mounting groove and fits tightly to the inner side of the mounting groove.

[0013] By adopting the above technical solution, the sealing effect inside the installation groove can be improved by the sealing plate, preventing external dust from entering the interior of the control panel.

[0014] Furthermore, one end of the connecting rod is fixedly connected to the card block, and the other end of the connecting rod extends to the outside of the fixed block. A spring is sleeved on the outside of the connecting rod. The connecting rod and the card block are movably connected to the fixed block through the spring, and the card block is engaged with the card slot.

[0015] By adopting the above technical solution, the protective cover can be limited by the connection between the clamping block and the clamping slot, and the clamping block can be telescopically moved by the expansion and contraction action of the spring, which is convenient for engagement.

[0016] In summary, the beneficial technical effects of the utility model are:

[0017] A protective cover, a spring, a card block and a sealing plate are used. A torsion spring is added to the component connecting the protective cover and the outside of the box body, so that the protective cover can be automatically popped open. At the same time, by pulling the connecting rod and the expansion and contraction action of the spring, the card block can be quickly stretched and moved to facilitate engagement with the card slot. The sealing plate can be sealed and connected to the installation slot, thereby improving the sealing effect of the connection and making it easier to use. BRIEF DESCRIPTION OF THE DRAWINGS
