[0018] This utility model provides a remote-controlled floor grinding machine. It has the following beneficial effects:

[0019] 1. This remote-controlled floor grinder uses two reversible, perforated telescopic rods as handles. The position is adjusted by rotating the handles around the support base. Since the handles are tilted towards both sides of the vehicle body, the force applied during use differs. The rotation of the perforated telescopic rods allows for pushing or pulling the vehicle body, easily adapting to the user's force application habits, thus increasing flexibility and convenience. To lock the position and angle of the perforated telescopic rods, a locking block is pushed away from the stop block. After rotating the perforated telescopic rod, the locking block moves to the other side of the support base. Releasing the locking block brings it closer to the stop block, which engages with the notch to lock the perforated telescopic rod. This allows for flexible and convenient adjustment and locking of the perforated telescopic rods, making it easy to use and simple to operate. Furthermore, the rotation of the perforated telescopic rods allows them to be stored above the vehicle body, reducing their protruding length and minimizing interference with the vehicle's movement.

[0020] 2. This remote-controlled floor grinder connects two pull rods via a connecting rod. When adjusting the perforated telescopic rod, the connecting rod can be pulled by hand, causing the two pull rods to slide along the corresponding ear plates. The pull rods cause the locking block to approach the ear plates and compress the spring. When the perforated telescopic rod rotates to the appropriate position, the connecting rod is released, and the locking block resets under the spring force and engages with the stop block on the other side of the locking block again, thus adjusting the position of the perforated telescopic rod. Another crossbar is fixedly installed at the end of the perforated telescopic rod for gripping and pushing the entire device. The position of the perforated telescopic rod can be adjusted by placing the web of the hand against the crossbar and gripping the connecting rod with the fingers. The operation and use are highly convenient. Attached Figure Description

[0027] A remote-controlled floor grinder, such as Figure 1 and Figure 2 As shown, it includes:

[0028] The vehicle body 10 has a height-adjustable grinding head 11 on one side and a support base 12 fixedly installed on the other side. The support base 12 is rotatably connected to a perforated telescopic rod 13 for support. Specifically, an electric push rod is fixedly installed on the top of the vehicle body 10. The grinding head 11 is fixedly connected to the output shaft of the electric push rod to realize the lifting and lowering of the grinding head 11. The grinding head 11 includes a housing. A motor is fixedly installed on the top of the housing. A grinding disc connected to the output shaft of the motor is rotatably connected to the bottom of the housing. The grinding disc is rotated to grind and level the ground.

[0029] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a limiting structure is set between the support base 12 and the perforated telescopic rod 13 for adjusting and locking the position of the perforated telescopic rod 13. The limiting structure includes a locking block 14, a stop block 15, and a notch 16. Stop blocks 15 are fixedly set on both sides of the support base 12. The locking block 14 is elastically connected to the perforated telescopic rod 13. The locking block 14 has a notch 16. The stop block 15 can be locked into the notch 16 to restrict the rotation of the perforated telescopic rod 13. The support base 12 is welded and fixed to the top of the vehicle body 10. A rotating shaft is fixedly installed on both sides of the support base 12. The perforated telescopic rod 13 has a shaft hole. The rotating shaft passes through the shaft hole and is limited by a retaining spring. The stop block 15 forms a semi-circular cylindrical structure. The stop blocks 15 on both sides of the support base 12 are arranged in a ring array. The distribution center of the stop blocks 15 is concentric with the rotating shaft. The locking block 14 is a rectangular block. A notch 16 is opened on the end of the locking block 14 near the stop block 15. The notch 16 forms an arc-shaped groove that fits with the stop block 15 with clearance.

[0030] In this design, two reversible perforated telescopic rods 13 serve as handrails. The position of the handrails is adjusted by rotating them around the support base 12. Since the force exerted on the handrails differs depending on their orientation relative to the sides of the vehicle body 10, the rotation of the perforated telescopic rods 13 allows for pushing or pulling the vehicle body 10, facilitating adjustments based on the user's force application habits and enhancing flexibility and convenience. To lock the position and angle of the perforated telescopic rods 13, the locking block 14 is pushed away from the stop block 15. After rotating the perforated telescopic rods 13, the locking block 14 moves to the other side of the support base 12. Releasing the locking block 14 causes it to approach the stop block 15, which then engages with the notch 16 to lock and limit the perforated telescopic rods 13. This allows for flexible and convenient adjustment and locking of the perforated telescopic rods 13, making it easy to use and simple to operate.

[0031] like Figure 4 As shown, the limiting structure also includes a pull rod 20 and an ear plate 22. The ear plate 22 is fixedly connected to the telescopic rod 13 with holes. The pull rod 20 is slidably connected to the ear plate 22. A spring is provided between the ear plate 22 and the locking block 14. The ear plate 22 has a through hole adapted to the pull rod 20. The pull rod 20 is slidably disposed in the hole. The end of the pull rod 20 is fixedly connected to the end face of the locking block 14. The spring is sleeved on the pull rod 20. The two ends of the spring abut against the end faces of the ear plate 22 and the locking block 14 respectively. There are two pull rods 20. The two pull rods 20 are parallel to each other. The ends of the two pull rods 20 are fixedly connected to a connecting rod 21.

[0032] In this design, to facilitate control of the locking block 14, a connecting rod 21 is used to connect two pull rods 20. When adjusting the perforated telescopic rod 13, the connecting rod 21 can be pulled by hand. The connecting rod 21 drives the two pull rods 20 to slide along the corresponding ear plates 22. The pull rods 20 drive the locking block 14 to approach the ear plates 22 and compress the spring deformation. When the perforated telescopic rod 13 rotates to the appropriate position, the connecting rod 21 is released. The locking block 14 resets under the elastic force of the spring and engages with the stop block 15 on the other side of the locking block 14 again, thereby adjusting the position of the perforated telescopic rod 13. Another crossbar is fixedly installed at the end of the perforated telescopic rod 13 for the palm to hold and push the entire device. The position of the perforated telescopic rod 13 can be adjusted by pressing the crossbar against the palm and hooking the connecting rod 21 with the fingers. The operation and use are highly convenient.

[0033] The working principle of this utility model is as follows: By setting a connecting rod 21 to connect two pull rods 20, when adjusting the perforated telescopic rod 13, the connecting rod 21 can be pulled by hand. The connecting rod 21 drives the two pull rods 20 to slide along the corresponding ear plate 22. The pull rod 20 drives the locking block 14 to approach the ear plate 22 and squeezes the spring to deform. When the perforated telescopic rod 13 rotates to the appropriate position, the connecting rod 21 is released. The locking block 14 is reset under the elastic force of the spring and engages with the stop block 15 on the other side of the locking block 14 again, thereby realizing the position adjustment of the perforated telescopic rod 13. Another crossbar is fixedly installed at the end of the perforated telescopic rod 13 for the palm to hold and push the entire device. By using the position of the thumb and forefinger of the palm to touch the crossbar and the fingers to hold the connecting rod 21, the position of the perforated telescopic rod 13 can be adjusted. The two flippable perforated telescopic rods 13 serve as handrails. The position can be adjusted by rotating the handrails around the support base 12, thereby realizing the pushing or pulling of the entire device.

[0034] The bottom of the vehicle body 10 is equipped with a hub motor to provide driving force, and the top of the vehicle body 10 is equipped with a remote control device: a magnetic remote control or a wireless control module, which supports remote start, stop, speed adjustment and steering operations.

[0035] Control box: Integrated into the main body, it receives remote control signals and controls the operation of actuators such as drive motors and hub motors to achieve remote control function.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
