DETAILED DESCRIPTION

The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As shown in FIGS. 1 to 5 , this embodiment provides a shock-absorbing base for a fan, which is used to reduce vibration and noise when the fan is working, including:

A mounting base 2 is arranged at the bottom of the fan 1;

The first shock absorbing member 5 is arranged in the middle of the bottom surface of the mounting seat 2.

The base 3 is located below the mounting seat 2, and the first shock absorbing member 5 is installed between the base 3 and the mounting seat 2;

The connecting rod mechanism 4 is hinged between the mounting seat 2 and the base 3 , and the connecting rod mechanism 4 is used to support the mounting seat 2 .

In the above scheme, it should be noted that the exhaust fan of this scheme is a centrifugal fan, and the fan 1 is installed in the mounting seat 2. When the fan is running, the first shock absorber 5 can reduce the vibration effect of the fan 1 on the base 3, and the connecting rod mechanism 4 will slide along the bottom of the mounting seat 2 when the mounting seat 2 moves downward, always supporting the mounting seat 2 to prevent the single first shock absorber 5 from failing to effectively maintain the overall stability of the mounting seat 2 and causing the fan 1 to fall.

Furthermore, the mounting base 2 comprises:

The seat body has a groove 202 formed inside;

There are multiple limiting protrusions 203, which are symmetrically arranged in the groove 202. The limiting protrusions 203 are used to support the bottom surface of the fan 1; the limiting protrusions 203 are rubber blocks.

A slideway 204 is provided at the bottom of the groove 202;

An elastic member 205, both ends of which are slidably disposed in the groove 202;

The supporting seat 206 is disposed in the middle of the elastic member 205 , and the middle of the supporting seat 206 contacts the bottom of the fan 1 .

In the above scheme, the limiting protrusion 203 is arranged obliquely to support the fan 1. It should be noted that there are four limiting protrusions 203, which support the position of the bottom of the fan 1, and the four limiting protrusions 203 can stably install the fan 1 in the groove 202 during operation. Since the bottom of the fan 1 is circular, the upper surface of the supporting seat 206 also needs to be provided with an arc groove adapted to the bottom surface of the fan 1. When the fan 1 is placed on the limiting protrusion 203, the bottom of the fan 1 will be installed in the arc groove. Since the lower part of the supporting seat 206 is provided with an elastic member 205, the vibration generated by the fan 1 during operation will also be absorbed by the elastic member 205, thereby improving the shock absorption effect.

It should also be noted that the elastic member 205 is an arc-shaped spring sheet. When the fan 1 vibrates, the rubber limiting protrusion 203 will play a buffering role to prevent the fan 1 from completely squeezing the elastic member 205 and causing the elastic member 205 to lose its elasticity. Since the limiting protrusion 203 also has a small elastic effect, the limiting protrusion 203 and the elastic member 205 can cooperate to achieve preliminary shock absorption of the fan 1.

Furthermore, the first shock absorbing member 5 comprises:

The fixed cylinder 501 is arranged in the middle of the base 3;

The piston rod 503 is slidably disposed in the fixed cylinder 501, and one end of the piston rod 503 away from the fixed cylinder 501 is fixedly connected to the middle of the bottom surface of the mounting seat 2;

The first spring 502 is sleeved on the piston rod 503 , one end of the first spring 502 is fixedly connected to the inner bottom of the fixed cylinder 501 , and the other end of the first spring 502 is fixedly connected to the end of the piston rod 503 away from the fixed cylinder 501 .

In the above scheme, the first shock absorber 5 is arranged at the center of gravity of the base 3. The first shock absorber 5 is used to achieve secondary shock absorption. When the fan 1 drives the mounting base 2 to vibrate, the piston rod 503 can achieve shock absorption on the bottom of the mounting base 2 under the action of the first spring 502. By reducing the vibration of the base 3 and the mounting base 2, the noise during the operation of the exhaust fan can be reduced.

Furthermore, the connecting rod mechanism 4 is provided with multiple groups, and each group of the connecting rod mechanism 4 includes:

A first hinge seat 402 is slidably disposed on the bottom surface of the mounting seat 2;

The second hinge seat 403 is arranged on the upper surface of the base 3;

Mount 2 also includes:

There are multiple slide grooves 201 , and the multiple slide grooves 201 are all opened on the bottom surface of the mounting seat 2 , and the first hinge seat 402 is slidably connected to the slide grooves 201 .

The connecting rod 401 has one end hinged to the first hinge seat 402 and the other end hinged to the second hinge seat 403. The connecting rod 401 is arranged tilted.

In the above solution, the connecting rod 401 is connected to the mounting seat 2 through the first hinge seat 402, and the connecting rod 401 is connected to the base 3 through the second hinge seat 403. It should be noted that when the mounting seat 2 descends, the first hinge seat 402 will slide along the slide groove 201 to ensure that the connecting rod 401 can be quickly deflected. The connecting rod 401 structure can play a strong supporting role for the mounting seat 2.

Furthermore, it also includes:

The protective frame 6 is arranged on the side wall of one side of the mounting seat 2, the protective frame 6 is L-shaped, and the side of the protective frame 6 away from the mounting seat 2 is connected to the top surface of the fan 1; the protective frame 6 includes: a vertical rod 602, fixedly arranged on the side wall of the mounting seat 2; a horizontal rod 601, fixedly connected to the end of the vertical rod 602 away from the mounting seat 2, and a gap is left between the horizontal rod 601 and the top surface of the fan 1; a circular groove is opened in the horizontal rod 601, and the opening direction of the circular groove is toward one side of the fan 1, and the second shock absorber 7 is installed in the circular groove.

The second shock absorbing member 7 is disposed between the anti-slip frame and the top surface of the fan 1, and is used to provide downward pressure on the fan 1. The second shock absorbing member 7 includes: a T-shaped rod 701, which is slidably disposed in the circular groove, and one end of the T-shaped rod 701 abuts against the top wall of the fan 1; a second spring 702, which is sleeved on the T-shaped rod 701, and one end of the second spring 702 located inside the circular groove is fixedly connected to the bottom of the circular groove.

In the above scheme, the protective frame 6 is used to limit the top of the fan 1 to prevent the fan 1 from falling off the mounting base 2 during vibration. It should be noted that the connection method between the T-bar 701 in the second shock absorber 7 and the second spring 702 is the same as the connection method of the first shock absorber 5.

Further, the base 3 also includes: an anti-skid pad 301, which has multiple anti-skid pads 301, and the multiple anti-skid pads 301 are respectively arranged at the corners of the bottom surface of the base 3. The anti-skid pad 301 can prevent the base 3 from being displaced due to vibration. At the same time, the anti-skid pad 301 is a rubber pad, which can also reduce noise.

Working process: During installation, first place the fan 1 in the groove 202 of the mounting seat 2, the bottom surface of the fan 1 abuts against the limiting protrusion 203 and contacts the arc groove of the supporting plate, then install the protective frame 6 on the side wall of the mounting seat 2, and abut the second shock absorbing member 7 against the bottom of the fan 1. During operation, when the fan 1 is running, the vibration generated by the fan 1 will first be partially absorbed by the second shock absorbing member 7, the limiting protrusion 203 and the elastic member 205, initially reducing the vibration effect and reducing noise, and the first shock absorbing member 5 will further absorb the vibration received by the mounting seat 2, reducing the vibration effect again, and thus reducing noise.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
