[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0030] like Figures 1-11 As shown, a shock-absorbing motor mounting bracket is provided with a motor body 2 above the bracket body 1, and buffer grooves 8 are provided at three U-shaped positions on the upper surface of the bracket body 1. An O-ring 6 is movably sleeved inside the buffer groove 8, and a mounting groove 13 and three arc grooves 11 are provided on the lower surface of the top of the bracket body 1. The three arc grooves 11 are located on the outside of the mounting groove 13, and a rubber ring 10 is inserted into the inside of the mounting groove 13. The lower surface of the motor body 2 is threadedly connected with three self-tapping screws 7 that pass through the gasket 3, the bracket body 1, and the rubber ring 10. The periphery of the bracket body 1 is rounded to facilitate the processing of the bracket body 1.
[0031] During use, insert the rubber ring 10 into the mounting groove 13, then place the motor body 2 above the bracket body 1, so that the output shaft of the motor body 2 passes through the bracket body 1 and the rubber ring 10 in sequence, and align the threaded holes on the rubber ring 10, the bracket body 1, and the motor body 2, rotate the self-tapping screw 7 to fix and lock the rubber ring 10, the bracket body 1, and the motor body 2, add an O-ring 6 at the three supporting points of the bracket body 1, and the center hole of the O-ring 6 is fixed to the supporting surface of other parts through the guide column, thereby effectively buffering the bearing shock damage caused by collision, ensuring the quality of the motor product, making the motor mounting bracket have a shock-absorbing effect, and improving the product service life. It can be used for large-scale production and technical research and development of motor product installation.
[0032] like Figure 2-Figure 8 As shown, a protective sleeve 9 is fixedly installed on the upper surface of the top of the bracket body 1. The cross-section of the protective sleeve 9 is a T-shaped structure, and the material of the protective sleeve 9 is rubber.
[0033] The protective sleeve 9 is provided to protect the output shaft of the motor, thereby preventing the output shaft from directly contacting the bracket body 1 and the rubber ring 10 and causing wear, thereby extending the service life of the bracket and the motor output shaft.
[0034] like Figures 1-8 As shown, anti-skid pads 5 are fixedly installed on three sides of the lower surface of the bottom of the bracket body 1, and the material of the anti-skid pads 5 is silicone.
[0035] The anti-skid pad 5 made of silica gel can provide an anti-skid effect, thereby improving the stability of the bracket during installation and use.
[0036] like Figure 2-Figure 9 As shown, the buffer groove 8 is in the shape of a water drop, the cross section of the O-ring 6 is in an I-shaped structure, and the lower part of the O-ring 6 is in a conical shape. The material of the O-ring 6 is rubber.
[0037] By adding O-rings 6 at the three supporting points of the bracket body 1, the center hole of the O-ring 6 is fixed through the guide column and the supporting surface of other parts, thereby effectively buffering the bearing shock damage caused by collision, ensuring the quality of the motor product, and making the motor mounting bracket have a shock-absorbing effect, thereby increasing the service life of the product and being used for large-scale production and technical research and development of motor product installation.
[0038] like Figure 2-Figure 8 、 Figure 11 As shown, the mounting groove 13 includes a slot 131 and two slots 132. The rubber ring 10 is plugged into the slot 131. Two protrusions 14 are fixedly mounted on the upper surface of the rubber ring 10. The height of the outer protrusion 14 is smaller than the height of the inner protrusion 14. The outer portion of the protrusion 14 is plugged into the inner portion of the slot 2 132.
[0039] When the rubber ring 10 is inserted into the first slot 131 , the two second slots 132 and the protrusion 14 can position the rubber ring 10 , thereby improving the installation effect of the rubber ring 10 and the bracket body 1 and facilitating the fixing of the rubber ring 10 .
[0040] like Figure 3-Figure 11 As shown, three grooves 12 are provided on the lower surface of the rubber ring 10, and the grooves 12 and the buffer grooves 8 are arranged in the same position, and the grooves 12 and the buffer grooves 8 are staggered with the arc grooves 11. The three grooves 12, the buffer grooves 8 and the arc grooves 11 are all distributed in a circular array. Three support columns 4 are fixedly installed on the upper surface of the bracket body 1, and the support columns 4 and the arc grooves 11 are arranged in the same position. A rubber gasket 3 is overlapped between the upper surface of the three support columns 4 and the lower surface of the motor body 2.
[0041] By providing three arcuate grooves 11, the weight of the bracket body 1 can be reduced. At the same time, the bracket body 1 is set into a shell shape, so that the bracket has the characteristic of being lightweight. The groove 12 and the buffer groove 8 are arranged in the same position, and the support column 4 and the arcuate groove 11 are arranged in the same position. The groove 12 and the buffer groove 8 are staggered with the arcuate groove 11. During installation, the threaded holes on the gasket 3, the motor body 2, the bracket body 1, and the rubber ring 10 are arranged in the same position, which facilitates the alignment of the threaded holes and reduces installation errors. The bracket body 1, the motor body 2, the gasket 3, and the rubber ring 10 can be quickly fixed, thereby improving the installation efficiency of the motor and the bracket.
[0042] The working principle of the present invention is as follows: when in use, place the gasket 3 on the upper end of the support column 4, insert the rubber ring 10 into the mounting groove 13, then place the motor body 2 on the gasket 3, make the output shaft of the motor body 2 pass through the gasket 3, the bracket body 1, and the rubber ring 10 in sequence, and align the threaded holes on the rubber ring 10, the bracket body 1, the gasket 3, and the motor body 2, rotate the self-tapping screw 7 to fix and lock the rubber ring 10, the bracket body 1, the gasket 3, and the motor body 2, add O-rings 6 at the three supporting points of the bracket body 1, and the middle hole of the O-ring 6 is connected to the guide column and other parts. The supporting surface is fixed, which effectively cushions the bearing shock damage caused by collision, ensures the quality of the motor product, makes the motor mounting bracket have a shock-absorbing effect, and improves the service life of the product. The anti-slip pad 5 made of silicone material can play an anti-slip effect, and improves the stability of the bracket during installation and use. The protective sleeve 9 is provided to protect the output shaft of the motor, avoiding direct contact between the output shaft and the bracket body 1 and the rubber ring 10 to cause wear, thereby extending the service life of the bracket and the motor output shaft, and can be used for a large number of production and technical research and development of motor products.
[0043] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
