Description

Technical Field

[0001] The utility model relates to the field of eccentric block motors, and particularly relates to an eccentric block motor with adjustable eccentric distance. Background Technique

[0002] An eccentric block motor is a special motor that realizes vibration through the centrifugal force generated by an eccentric mass when the motor rotates. When the motor rotates, the eccentric mass periodically deviates from the equilibrium position, thereby generating periodic vibration. This vibration can be transmitted to the human body through the surface in contact with the human body (such as a mattress, a seat cushion, a massage cushion, etc.), so as to achieve the effect of massage or rehabilitation treatment.

[0003] An eccentric block motor consists of a motor main body, a rotating shaft and an eccentric block, and the eccentric block is the core part for realizing vibration. In the existing eccentric block motors, the eccentric block is fixedly connected to the rotating shaft, and the eccentric distance of the eccentric block relative to the rotating shaft cannot be adjusted. The eccentric vibration effect of the whole motor is fixed and unchanged, and the flexibility and adaptability in use are poor, and the use effect is average. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an eccentric block motor with adjustable eccentric distance, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

Detailed Embodiments

[0019] When using the eccentric block motor, the motor main body 1 is installed through the cooperation of the mounting plate 4 and the mounting holes 5 with screws. The eccentric distance of the eccentric block structure 3 is adjusted according to needs. After the adjustment, when the motor main body 1 is started, the rotating shaft 2 drives the eccentric block structure 3 to rotate, so as to achieve the effect of eccentric vibration, and the eccentric vibration can be used for rehabilitation massage.

[0020] Through the above implementation, the eccentric block structure 3 includes an eccentric block main body 301, a U-shaped groove 302, a movable groove 303, an adjusting block 304, and a limiting component 305. The U-shaped groove 302 and the movable groove 303 are formed on the eccentric block main body 301, and the eccentric block main body 301 is connected to the end of the rotating shaft 2. The adjusting block 304 is arranged in the U-shaped groove 302 and the movable groove 303 on the eccentric block main body 301. The limiting component 305 is installed on the eccentric block main body 301. The eccentric block structure 3 further includes a limiting groove 306, an adjusting hole 307, and an adjusting bolt 308. The limiting groove 306 is formed on the eccentric block main body 301. The adjusting hole 307 is arranged on the eccentric block main body 301, and the adjusting hole 307 communicates with the limiting groove 306. The adjusting bolt 308 is connected in the adjusting hole 307 on the eccentric block main body 301, and the lower end of the adjusting bolt 308 is located in the limiting groove 306. The eccentric block main body 301 is connected to the corresponding limiting component 305 through the limiting groove 306. The four limiting components 305 are equidistantly linearly distributed on the eccentric block main body 301. The limiting component 305 includes a circular groove 3051, a threaded groove 3052, a connecting block 3053, a threaded joint 3054, a hexagonal groove 3055, a limiting post 3056, a through hole 3057, and a spring 3058. The circular groove 3051 and the threaded groove 3052 are formed on the circular groove 3051. The connecting block 3053 is fixedly connected to the threaded joint 3054, and the threaded joint 3054 is connected in the threaded groove 3052. The hexagonal groove 3055 is formed on the connecting block 3053. The through hole 3057 is formed on the limiting post 3056, and the lower end of the limiting post 3056 is located in the circular groove 3051. The spring 3058 is connected between the connecting block 3053 and the limiting post 3056. By providing the eccentric block structure 3, the eccentric block main body 301 is connected to the rotating shaft 2 through the adjusting block 304. When used in cooperation with the limiting component 305, the relative position of the eccentric block main body 301 can be adjusted at a specific spacing, thereby changing the eccentric distance and the vibration effect, making the use of the entire motor more flexible and variable. Structures such as the spring 3058 and the limiting post 3056 are provided in the limiting component 305, which can ensure the connection stability between the adjusting block 304 and the eccentric block main body 301. At the same time, the limiting post 3056 can be telescoped through the spring 3058, ensuring the use effect of the limiting component 305. By arranging the adjusting bolt 308 in the adjusting hole 307, the limiting component 305 can be pushed down to contract, facilitating the adjustment of the position of the adjusting block 304. When the adjusting bolt 308 moves upward, the corresponding limiting component 305 can quickly extend for limiting, without affecting the limiting effect.

[0021] When installing the eccentric block structure 3, the rotating shaft 2 is fixedly connected to the adjusting block 304. A limiting component 305 is arranged on the eccentric block body 301. During installation, the connecting block 3053, spring 3058 and limiting column 3056 in the limiting component 305 are arranged in the circular groove 3051. The threaded joint 3054 contacts the threaded groove 3052. The long rod in the hexagonal wrench passes through the through hole 3057 and is connected to the hexagonal groove 3055. By rotating the connecting block 3053 with the hexagonal wrench, the threaded joint 3054 is screwed into the threaded groove 3052, thus completing the installation of the limiting component 305. Install all the limiting components 305 according to the above process. Subsequently, the eccentric block body 301 can be set on the adjusting block 304 through the U-shaped groove 302 and the movable groove 303 and can be used. During use, the U-shaped groove 302 and the movable groove 303 play a limiting role on the adjusting block 304 in the direction perpendicular to the U-shaped groove 302. The upper end of the limiting component 305 is inserted into the limiting groove 306, playing a limiting role on the adjusting block 304 in the direction parallel to the U-shaped groove 302, ensuring the connection stability between the adjusting block 304 and the eccentric block body 301. Subsequently, start the motor and perform eccentric vibration. If it is necessary to adjust the eccentric distance, the adjusting bolt 308 in the adjusting hole 307 can be rotated. The adjusting bolt 308 descends and pushes the limiting column 3056, causing the limiting column 3056 to descend and compress the spring 3058 until the upper end of the limiting column 3056 is flush with the surface of the eccentric block body 301. Subsequently, the eccentric block body 301 can move relative to the adjusting block 304. When moving to the next limiting component 305, directly press the limiting component 305 to make way, and then continue to move the eccentric block body 301. Proceed in this way until the eccentric block body 301 and the adjusting block 304 are adjusted to a suitable relative position. Subsequently, rotate the adjusting bolt 308 to make way. The spring 3058 in the limiting component 305 elongates, causing the limiting column 3056 to be inserted into the limiting groove 306 to achieve limiting fixation. In this way, the eccentric distance is changed. After the eccentric distance is adjusted, the eccentric block motor can be used continuously.
