Description

Technical Field

[0001] The utility model relates to the technical fields of centrifugal fans and shock absorber seats, and mainly relates to a slidable shock absorber seat for a centrifugal fan. Background Art

[0002] As Figure 1 shown, the conventional fixing structure and method of a shock absorber for a centrifugal fan mainly include a centrifugal fan 1, a motor 2, a shock absorber 3, a base 4 and a bracket 5. The motor 2 and the centrifugal fan 1 are installed on the bracket 5. The motor shaft and the fan shaft are connected by a belt 6. Four shock absorbers 3 are arranged between the bracket 5 and the base 4. As Figure 2 shown, the shock absorber 3 is fixed to the bracket 5 by bolts 7 and nuts 8.

[0003] The disadvantages of the existing structure are as follows: Before installation, the positioning and movement of the fan air outlet 9 and the unit air outlet are rather troublesome. The unit and the unit air outlet are not shown in the figure. The unit air outlet is used to correspond and match with the fan air outlet 9. If the positions of the subsequent unit and the unit air outlet are changed, the bracket 5, a sheet metal part, needs to be re-drilled with bolt holes, which will cause the disassembly and movement of the overall fan and motor assembly to be time-consuming and laborious. Since the bottom of the bolt 7 is suspended without support (as Figure 2 ), only the nut 8 is used to fix the shock absorber 3 and the bracket 5. During operation, the vibration of the motor 2 and the centrifugal fan 1 may cause the nut 8 to loosen, and finally the bolt 7 may fall off. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies existing in the prior art and provide a slidable shock absorber seat for a centrifugal fan.

[0005] The purpose of the utility model is achieved by the following technical solutions. A slidable shock absorber seat for a centrifugal fan includes a bracket and a square steel. Among them, the bracket is used to install the centrifugal fan and the motor. A group of shock absorbers are arranged at the bottom of the bracket. The shock absorbers are slidably connected to the square steel through shock absorber sliders, so that the fan air outlet of the centrifugal fan matches the position of the unit air outlet by sliding the shock absorber sliders.

[0006] Furthermore, the cross-section of the shock absorber slider is a frame structure with an opening at the bottom. The top surface and the two side surfaces of the shock absorber slider are respectively fitted and connected with the top surface and the two side surfaces of the square steel. Bolts pass through the top surface of the shock absorber slider and cooperate with nuts to fixedly connect the shock absorber slider and the shock absorber together.

[0007] Furthermore, a group of screw holes are arranged on the two side surfaces of the shock absorber slider. When the shock absorber slider moves to the position where the fan air outlet matches the unit air outlet, the shock absorber slider and the square steel are fixedly connected together through self-tapping screws and the screw holes.

[0008] Furthermore, a raised portion is provided on the top surface of the shock absorber slider, and a groove matching the head of the bolt is provided inside the raised portion, so that the head of the bolt is flush with the top surface of the shock absorber slider after assembly.

[0009] Furthermore, the motor is mounted on the bracket through a slide rail, and the motor shaft and the fan shaft are connected by belt drive. The tension of the belt is adjusted by moving the position of the motor on the bracket.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. The U-shaped base is changed to two square steels, and a shock absorber slider matching the square frame is added, which facilitates the overall sliding when calibrating the positions of the fan air outlet and the unit air outlet. The shock absorber and the shock absorber slider are connected by bolts and nuts with high strength, and the shock absorber slider is sleeved on the square steel to increase the contact area between the shock absorber slider and the square steel.

[0012] 2.

[0025] The present utility model will be further described below in conjunction with the drawings and the detailed implementation manners. It should be noted that, on the premise of no conflict, any combination can be formed between the following described embodiments or technical features to form new embodiments.

[0026] As Figures 3 - 7 shown, a slidable shock absorber seat for a centrifugal fan includes a centrifugal fan 1, a motor 2, a bracket 5 and a square steel 11. The centrifugal fan 1 and the motor 2 are installed on the bracket 5. The motor 2 is installed on the bracket 5 through two slide rails 13. The motor shaft and the fan shaft are connected by a belt 6 for transmission. By moving the position of the motor 2 on the bracket 5, the tension of the belt 6 is adjusted. Four shock absorbers 3 and two square steels 11 are provided at the bottom of the bracket 5. The shock absorbers 3 are slidably connected to the square steels 11 through shock absorber sliders 10, so that the fan air outlet 9 of the centrifugal fan 1 matches the position of the unit air outlet by sliding the shock absorber sliders 10.

[0027] The key point in the design and installation of the shock absorber slider is that when the fan air outlet and the unit air outlet do not align during the installation of the fan motor, it is convenient to move the whole to achieve the purpose of calibration. The specific structure of the shock absorber slider 10 is as Figures 8 - 10 shown. The cross-section of the shock absorber slider 10 is a frame structure with an opening at the bottom. The top surface and two side surfaces of the shock absorber slider 10 are respectively fitted and connected with the top surface and two side surfaces of the square steel 11. The bolt 7 passes through the top surface of the shock absorber slider 10 and cooperates with the nut 8 to fixedly connect the shock absorber slider 10 and the shock absorber 3 together. With the shock absorber installation method using the shock absorber slider, it is convenient to slide the whole when calibrating the positions of the fan air outlet and the unit air outlet. The connection between the shock absorber and the shock absorber slider with bolts and nuts has high strength, and the shock absorber slider is sleeved on the square steel to increase the contact area between the shock absorber slider and the square steel.

[0028] During installation, the centrifugal fan 1 and the motor 2 are installed on the bracket 5. The shock absorber 3 and the shock absorber slider 10 are first fixedly connected with bolts 7 and nuts 8, and after being connected, they are installed at the bottom of the bracket. The shock absorber slider 10 is sleeved on the square steel 11, and the head of the bolt 7 abuts against the square steel 11, and the square steel 11 plays a role in supporting the bolt 7. There is a protruding part at the top of the shock absorber slider 10, and a groove matching with the head of the bolt 7 is arranged in the protruding part, reserving space for the head of the fixing bolt to avoid leaving a gap for the bolt head between the slider and the square steel, ensuring that the shock absorber slider 10 is completely fitted with the square steel 11.

[0029] Three screw holes 10-1 are arranged on both side surfaces of the shock absorber slider 10. When the shock absorber slider 10 moves to the position where the air outlet 9 of the fan matches the air outlet of the unit, the shock absorber slider 10 and the square steel 11 are fixedly connected together through self-tapping screws 12 and the screw holes 10-1. Tapping self-tapping screws at multiple hole positions ensures that the shock absorber slider will not slide during the operation of the fan motor, and can effectively prevent the overall detachment of the large fan and the large motor.

[0030] It can be understood that for those skilled in the art, equivalent replacement or change of the technical solution and the inventive concept of the present utility model should fall within the protection scope of the appended claims of the present utility model.
