Description

Technical Field

[0001] The present application relates to the field of ceiling fans, and in particular to an industrial ceiling fan that is easy to install. Background Art

[0002] Industrial ceiling fans are a common industrial machine widely used in large spaces such as industrial plants, logistics warehouses, waiting rooms, exhibition halls, gymnasiums, supermarkets, etc. for space ventilation and personnel cooling.

[0003] For example, the utility model patent with patent announcement number CN217682353U discloses an industrial ceiling fan, including a mounting base, an extension rod, a fan hub, a motor, fan blades and a protective device. The extension rod is installed on the mounting base, and the fan hub and the motor are installed on the end of the extension rod in sequence from top to bottom. The protective device includes a first protective device, a second protective device and a third protective device for preventing the fan blades from falling off radially. The third protective device passes through each fan blade in sequence. The fan blade has a cavity, and the fan hub is provided with protrusions with equal intervals of angles. The protrusions are arranged one-to-one corresponding to the fan blades. The protrusions are inserted into the cavities of the fan blades and are connected to the fan blades by fastening bolts.

[0004] When the above industrial ceiling fan is used, multiple bolts need to be used to penetrate the fan blades and the protrusions for connection when installing the fan blades. This operation is relatively troublesome and needs to be improved. Summary of the Invention

[0005] In order to improve the above problems, the present application provides an industrial ceiling fan that is easy to install.

[0006] This application provides an easy-to-install industrial ceiling fan, which adopts the following technical solutions:

[0007] An industrial ceiling fan that is easy to install comprises a suspension rod, a mounting base provided on the suspension rod, a motor provided on the mounting base and a plurality of fan blades, the fan blades being provided with an insert block, the mounting base being provided with a slot for the insert block to be inserted into, a slider being provided on the mounting base for lifting and sliding, the slider being provided with a plurality of blocks, the blocks corresponding to the fan blades one-to-one, the fan blades being provided with a through hole for the blocks to be inserted into, a groove being provided on the slider, a guide surface being provided on the inner wall of the groove, the guide surface being located on a side of the groove close to the slot and tilted outward in a direction close to the slot, an adjusting rod being threadedly connected to the mounting base, the adjusting rod abutting the guide surface, an elastic member being provided on the mounting base, the elastic member abutting the slider so that the slider has a tendency to move away from the slot.

[0008] By adopting the above technical solution, when the fan blades need to be installed, the plug blocks on each fan blade are inserted into the corresponding slots, and then the adjusting rod is twisted to move the adjusting rod close to the slider. The adjusting rod presses against the guide surface and pushes the slider along the guide surface to move close to the plug blocks, so that each card block is inserted into the corresponding through hole. By abutting the inner wall of the through hole with the card block, several blades can be positioned. Only by twisting the adjusting rod can the installation of several fan blades on the mounting base be completed, and the operation is easier.

[0009] Optionally, a clearance groove is provided on the inner wall of the slot away from the slider, and the clamping block is clamped into the clearance groove.

[0010] By adopting the above technical solution and providing a clearance groove, when the ceiling fan is working, the fan blades are pressed against the block through the inner wall of the through hole under the action of the centrifugal force generated by the operation of the ceiling fan, and the block is pressed against the inner wall of the clearance groove, thereby sharing the force and reducing the possibility of breakage at the connection between the block and the slider.

[0011] Optionally, an air inlet and an air outlet are provided on the mounting seat, the slider is arranged around the outer circumference of the motor, an air supply channel is provided in the slider, and the air supply channel is arranged around the outer circumference of the motor. When the block is inserted into the give way slot, the air inlet and the air outlet are both connected to the air supply channel.

[0012] By adopting the above technical solution, an air inlet, an air outlet and an air supply channel are set. When the ceiling fan is transported, the air supply channel is blocked by the mounting base to reduce the amount of debris falling into the air supply channel. After the fan blades are installed, the air inlet and the air outlet are connected to the air supply channel. When the ceiling fan is working, part of the indoor air flow flows through the air inlet, the air supply channel and the air outlet, thereby taking away the heat generated by the motor operation and improving the heat dissipation effect of the ceiling fan.

[0013] Optionally, the elastic member is located on a side of the slider close to the slot and on a side of the block close to the motor, and an upper end surface of the mounting seat is provided with a mounting groove for the elastic member and the slider to be inserted into.

[0014] By adopting the above technical solution, when the block or elastic part is damaged due to long-term use, the adjusting rod can be twisted to make the adjusting rod disengage from the groove, and the slider and elastic part can be taken out of the installation groove for replacement. Then, the intact elastic part and slider are inserted into the installation groove in turn, and the adjusting rod is twisted again so that the adjusting rod is inserted into the groove and abuts the guide surface. The replacement of the elastic part / slider can be completed, making the installation and replacement of the elastic part / slider more convenient.

[0015] Optionally, a limit block is provided on the inner wall of the installation groove, and a limit groove for the limit block to slide and engage in is opened on the sliding block.

[0016] By adopting the above-mentioned technical solution, a limit block and a limit groove are set, and the limit block abuts against the inner wall of the limit groove to limit the slider, so that the air inlet and the air outlet are located on the moving path of the air supply channel. When the subsequent card block is stuck in the clearance groove, the deviation of the air inlet and the air outlet from the air supply channel is reduced.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. When installing the fan blades, insert the inserts on each fan blade into the corresponding slots, then twist the adjustment rod to move the adjustment rod closer to the slider. The adjustment rod pushes the slider to move closer to the inserts, so that each block is inserted into the corresponding through-hole. You can then position several blades. Simply twist the adjustment rod to complete the installation of several fan blades on the mounting base, making the operation easier.

[0019] 2. By providing the clearance groove, when the ceiling fan is working, the fan blades are pressed against the block through the inner wall of the through hole under the action of the centrifugal force generated by the operation of the ceiling fan, and the block presses against the inner wall of the clearance groove, thereby sharing the force and reducing the possibility of breakage at the connection between the block and the slider;

[0020] 3. By setting the air inlet, air outlet and air supply channel, when transporting the ceiling fan, the air supply channel is blocked by the mounting base to reduce the entry of debris into the air supply channel. After the fan blades are installed, the air inlet and air outlet are connected to the air supply channel. When the ceiling fan is working, part of the indoor air flow flows through the air inlet, air supply channel and air outlet, thereby taking away the heat generated by the motor operation and improving the heat dissipation effect of the ceiling fan.
