Description

Technical Field

[0001] The utility model relates to the technical field of rolling shutter door installation, in particular to an anti-loosening rolling shutter door motor bracket plate. Background Art

[0002] The rolling door motor will generate vibration and impact during operation, which will cause the nuts used to connect the motor and the motor bracket plate to loosen under long-term action. The motor vibration is transmitted to the connection between the motor bracket plate and the wall through the motor bracket plate, causing the bolts and nuts used to connect the motor bracket plate and the wall to loosen. When the nuts at the connection between the motor and the motor bracket plate are loose, the motor will vibrate and displace during operation, the motor will run unstably, the motor noise will increase, and even the motor will burn out. When the bolts and nuts at the connection between the motor bracket plate and the wall are loose, the stability of the motor bracket plate will be affected, thereby affecting the normal operation of the motor and causing the motor vibration to increase. Therefore, there is an urgent need for a rolling door motor bracket plate that can prevent loosening to ensure the stability of the motor bracket plate and ensure that the motor runs stably with low noise. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a rolling shutter door motor bracket plate that is anti-loosening, which can improve the stability of the connection between the motor and the motor bracket plate, and improve the stability of the connection between the motor bracket plate and the wall, thereby ensuring stable operation of the motor with low noise.

[0004] The technical solution adopted by the utility model is as follows: a rolling shutter door motor bracket plate for preventing loosening, including a bracket plate body, the bracket plate body is provided with a plurality of extruded first protrusions, each of the first protrusions has a connecting plate on its inner surface, each of the first protrusions has a through hole, each of the first protrusions has a first connecting column for connecting the motor, one end of the first connecting column passes through the through hole to be connected to the connecting plate, the other end passes through the motor support foot and is threadedly connected with a nut, the first connecting column and the nut cooperate to limit the motor.

[0005] Principle of the technical solution:

[0006] The setting of the first protrusion, the connecting plate and the connecting column transforms the direct connection between the motor and the bracket plate body into a connection with the protrusion and the connecting plate. The protrusion can act as an elastic element to buffer the vibration, so that the vibration generated when the motor is running will first be transmitted to the connecting column, and then pass through the connecting plate and the protrusion. The vibration energy generated when the motor is running is partially absorbed by the connecting plate and the protrusion when passing through the connecting plate and the protrusion, that is, it is dispersed and buffered at the connecting plate and the protrusion, and then the remaining vibration energy is transmitted to the bracket plate body with a lower intensity, thereby reducing the influence of the motor vibration on the bracket plate body.

[0007] Compared with the prior art, the beneficial effects of the present invention are:

[0008] The connecting plate of the utility model can enhance the strength of the first protrusion, thereby increasing the stability of the connection between the first protrusion and the connecting column. The connecting plate and the first protrusion cooperate, and there is a damping effect at the connection between the connecting plate and the first protrusion, which can consume part of the vibration energy, thereby reducing the transmission of vibration, so that less vibration energy is transmitted to the bracket plate body, thereby improving the stability of the connection between the motor and the bracket plate body, and improving the stability of the connection between the bracket plate body and the wall, thereby ensuring that the motor runs stably, with uniform rotation speed and low noise.

[0009] As a preferred implementation manner of the present invention, the diameter of the via hole is greater than the diameter of the first connecting column.

[0010] Beneficial effect: The diameter of the via hole is larger than the diameter of the first connecting column, so that the first connecting column and the first protrusion are not directly connected, but are connected to the first protrusion through the connecting plate. In this way, the path of vibration energy transmission is first transmitted to the connecting plate through the connecting column, then transmitted to the first protrusion through the connecting plate, and then transmitted to the bracket plate body through the first protrusion, decreasing layer by layer, effectively absorbing and dispersing the vibration energy generated during the operation of the motor.

[0011] As a preferred embodiment of the present invention, a rubber sleeve is provided at one end of the first connecting column close to the connecting plate, and when the first connecting column passes through the motor support foot, the rubber sleeve fits against the inner wall of the motor support foot.

[0012] Beneficial effects: The rubber sleeve increases the friction between the motor support foot and the motor support foot, thereby enhancing the stability of the connection between the motor support foot and the first connecting column. Since the rubber sleeve itself has elastic and damping properties, the rubber sleeve will undergo elastic deformation and absorb part of the vibration energy, thereby reducing the transmission of vibration. The rubber sleeve can also play an isolating role, isolating the direct contact between the motor and the connecting column, thereby further reducing the transmission of vibration.

[0013] As a preferred embodiment of the present utility model, the bracket plate body is provided with a plurality of extruded second protrusions, and each of the second protrusions is provided with a second connecting column for connecting to a sprocket.

[0014] Beneficial effect: When the sprocket rotates, the sprocket is connected to the second protrusion through the second connecting column. Compared with the direct connection between the sprocket and the bracket plate body through the second connecting column, the second protrusion can be used as an elastic element to buffer the vibration.

It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present application.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] The reference numerals include: bracket plate body 1 , first protrusion 2 , through hole 201 , connecting plate 3 , first connecting column 4 , rubber sleeve 5 , second protrusion 6 , second connecting column 7 .

[0024] like Figure 1-5 As shown, the anti-loosening roller shutter door motor bracket plate, such as Figure 1 and Figure 5 As shown, the bracket plate body 1 includes a plurality of first protrusions 2 formed by extrusion, and a plurality of second protrusions 6 formed by extrusion. In this embodiment, the cross section of the first protrusion 2 is a flat-topped arch, and the second protrusion 6 is a semi-hollow sphere. Figure 3 and Figure 4 As shown, a connecting plate 3 is welded to the inner surface of each first protrusion 2. Figure 2 As shown, each first protrusion 2 is provided with a through hole 201, and a first connecting column 4 with one end passing through the through hole 201 is welded on the connecting plate 3. The diameter of the through hole 201 is larger than the diameter of the first connecting column 4. The outer end of the first connecting column 4 passes through the motor support foot and is threadedly connected with a nut. The first connecting column 4 and the nut cooperate to limit the motor.

[0025] A rubber sleeve 5 is provided at one end of the first connecting column 4 close to the connecting plate 3, and the diameter of the through hole 201 is equal to the sum of the diameters of the first connecting column 4 and the rubber sleeve 5. When the first connecting column 4 passes through the motor support foot, the rubber sleeve 5 fits against the inner wall of the motor support foot, and each second protrusion 6 is provided with a second connecting column 7 for connecting the sprocket.

[0026] In this embodiment, the bracket plate body 1 is connected to the wall by bolts.

[0027] In this embodiment, the bracket plate body 1 may be provided with a second protrusion 6, such as Figure 1 As shown, two second protrusions 6 may also be provided. Figure 5 shown.

[0028] The principle of preventing the nuts at the connection between the motor and the first connection column 4 and the connection between the bracket plate body 1 and the wall from loosening is explained as follows:

[0029] The bracket plate body 1 is connected to the wall through the through-hole bolts on the bracket plate body 1, and the motor legs are respectively sleeved on the corresponding first connecting columns 4 through the through-holes on the motor legs. The rubber sleeves 5 on the first connecting columns 4 fit with the side walls of the through-holes on the motor legs, and one end of the first connecting column 4 extending out of the through-holes on the motor legs is threadedly connected with a nut;

[0030] On the one hand, compared with the conventional first connecting column 4 directly connected to the bracket plate body 1, in this solution, the connecting plate 3 has a thickness. When the first connecting column 4 is connected to the connecting plate 3, the first protrusion 2 and the rubber sleeve 5 cooperate to provide support for the outer edge of the first connecting column 4, and then the connecting plate 3, the first protrusion 2 and the rubber sleeve 5 cooperate to provide stable support for the first connecting column 4, so that when the motor generates vibration during operation, the first connecting column 4 is stably connected to the nut to prevent the nut from loosening;

[0031] On the other hand, the motor generates vibration when it is running. The vibration energy generated by the motor is first transmitted to the rubber sleeve 5. The rubber sleeve 5 has elastic and damping characteristics. The rubber sleeve undergoes elastic deformation to absorb part of the vibration energy, and the remaining vibration energy is transmitted to the connecting plate 3 through the first connecting column 4. At this time, the surface area of ​​the connecting plate 3 is larger than the radial surface area of ​​the first connecting column 4, and there is a larger contact surface. The connecting plate 3 acts as a shock-absorbing layer to absorb and disperse the vibration energy and impact force transmitted from the motor to the bracket plate body 1. The remaining vibration energy is then transmitted to the first protrusion 2 through the connecting plate 3. The larger contact surface increases the damping effect between the connecting plate 3 and the first protrusion 2, and then transmitted from the first protrusion 2 to the bracket plate body 1, layer by layer, absorbing and dispersing the vibration energy generated by the motor, so that the vibration energy transmitted to the bracket plate body 1 is less, and the vibration energy on the first connecting column 4 is less, thereby improving the stability of the connection between the motor and the bracket plate body 1, and the stability of the connection between the bracket plate body 1 and the wall, thereby ensuring stable operation of the motor, uniform speed and low noise.

[0032] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
