[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0022] Example:
[0023] The present invention provides an angle-adjustable wall grinding device, which aims to solve the technical problem of easy deviation of grinding devices in the prior art.
[0024] See also Figures 1-4 , the utility model provides a technical solution:
[0025] A wall grinding device with adjustable angle includes a telescopic rod 1, the top end of the telescopic rod 1 is rotatably connected to a support frame 2, the inner side of the support frame 2 is sleeved with a motor 3, one end of the output shaft of the motor 3 is fixedly connected to a grinding disc 4, and by starting the motor 3 to drive the grinding disc 4, the unevenness of the wall surface can be polished flat, the outer periphery of the support frame 2 is fixedly sleeved with a slide rail 5, the outer side of the slide rail 5 is slidably connected to a stabilizing component 6, and the stabilizing component 6 is used to improve the stability of the grinding device during grinding work.
[0026] See also Figure 1-Figure 3 In this embodiment, the specific structure of the stabilizing component 6 is as follows:
[0027] The stabilizing assembly 6 includes a slider 601, an angle indicator 602, a stabilizing bolt 603, a rotating rod 604, and a smoothing plate 605. The slider 601 is movably engaged with the outer side of the slide rail 5. The angle indicator 602 is fixedly connected to one end of the top of the slider 601. The stabilizing bolt 603 is fixedly connected to the top of the slider 601 and the end away from the angle indicator 602. The rotating rod 604 is rotatably connected to the top of the angle indicator 602. The smoothing plate 605 is fixedly connected to the end of the rotating rod 604 away from the angle indicator 602.
[0028] First, see Figure 1 、 Figure 2 and Figure 3 The slider 601 slides on the outside of the slide rail 5, driving the smooth disc 605 to slide and adjust, and the slider 601 is fixed by the stabilizing bolt 603, thereby ensuring that the grinding disc 4 will not be hindered when grinding the wall. When grinding the wall, the angle between the smooth disc 605 and the grinding disc 4 can be adjusted by rotating the rotating rod 604, so that the grinding disc 4 can be conveniently used to grind walls at different angles. The operation is simple and convenient, which improves the convenience of using the device.
[0029] Second, see Figure 1 、 Figure 2 and Figure 4 The telescopic rod 1 and the support frame 2 are rotatably connected by a limit shaft 7. One end of the limit shaft 7 is provided with a tooth. One end of the limit shaft 7 with the tooth is sleeved on a limit clamp 8. The top of the limit clamp 8 is movably connected to one side of the bottom of the support frame 2. The top of the inner cavity of the limit clamp 8 is fixedly connected with a spring 9. The bottom end of the spring 9 is movably connected with a ball 10. The end of the ball 10 away from the spring 9 is engaged with the limit shaft 7. When in use, the limit clamp 8 can keep the telescopic rod 1 and the support frame 2 stable during rotation. At the same time, when the support frame 2 is rotated, the limit clamp 8 can be driven to rotate. At the same time, the spring 9 is under the action of the limit shaft 7, and the ball 10 is driven to roll inside the limit clamp 8. The ball 10 rolls over the top of the tooth and is clamped by the action of the spring 9.
[0030] For further information, see Figure 1 and Figure 2A through hole 11 is provided at one end of the telescopic rod 1 near the support frame 2. The telescopic rod 1 is a hollow metal tube. The telescopic rod 1 is divided into an outer tube and an inner tube. An adjusting bolt 12 is installed on the tube wall of the outer tube of the telescopic rod 1. A plurality of limiting holes 13 are provided at positions of the inner tube of the telescopic rod 1 corresponding to the adjusting bolts 12. The adjusting bolts 12 and the limiting holes 13 are adapted for use. When the device is used for work, it is necessary to polish walls of different heights. The outer tube and inner tube of the telescopic rod 1 can be telescopically adjusted by adjusting the bolts 12 and the limiting holes 13, so that the telescopic rod 1 can be adjusted to the required height, thereby improving the convenience of the device when in use.
[0031] For further information, see Figure 1 and Figure 2 The end of the motor 3 near the output shaft is movably connected with a dust cover 14, and one end of the cover head of the dust cover 14 corresponds to the position of the grinding disc 4. The cover head of the dust cover 14 is a soft plastic cover head, and a dust suction pipe 15 is fixedly connected to the outside of the dust cover 14. The end of the dust suction pipe 15 away from the dust cover 14 passes through the inner cavity of the telescopic rod 1 through the through hole 11, and the end of the dust suction pipe 15 passing through the inner cavity of the telescopic rod 1 is movably connected with a dust suction box 16. When the grinding disc 4 is used to grind the wall, the soft plastic cover head can cover the grinding disc 4. At the same time, the soft plastic cover head is close to the wall, which can prevent the dust generated during grinding from flying everywhere, and then the dust suction box 16 can be used to absorb the dust generated during grinding through the dust suction pipe 15, and the dust suction box 16 is a prior art. The dust suction box 16 can temporarily store dust to avoid the impact of dust on the environment, thereby improving the practicality of the device during use.
[0032] For further information, see Figure 3 The top of the angle indicator 602 is engraved with a scale bar, and the end of the rotating rod 604 close to the angle indicator 602 is engraved with an indicating arrow, which can assist in observing the angle value when the smooth disk 605 and the grinding disk 4 encounter the wall angle, which is convenient for secondary grinding.
[0033] The working process of the present invention is as follows: when using the device, first adjust the smoothing disc 605 to a position flush with the grinding disc 4 through the rotating rod 604, so that the smoothing disc 605 and the grinding disc 4 are in the same plane, and then slide the slider 601 to adjust the relative position of the smoothing disc 605 and the grinding disc 4 to ensure that the grinding disc 4 will not be obstructed when grinding the wall. When grinding the wall, the angle of the smoothing disc 605 and the grinding disc 4 can be adjusted by rotating the rotating rod 604, so that the grinding disc 4 can be conveniently used to grind walls of different angles. At the same time, the top of the angle indicator 602 is engraved with a scale bar, and the end of the rotating rod 604 close to the angle indicator 602 is engraved with an indicating arrow, which can assist in observing the relative position of the smoothing disc 605 and the grinding disc 4. The angle value when the grinding disc 4 encounters the wall angle is convenient for secondary grinding. During grinding, the smooth disc 605 and the grinding disc 4 will contact the wall at the same time. When grinding generates vibration, the sliding disc 605 can keep the grinding device stable to avoid deviation during the grinding process, so that the polished wall surface is smooth and flat. At the same time, when the wall is polished by the grinding disc 4, the soft plastic cover head can cover the grinding disc 4. At the same time, the soft plastic cover head is close to the wall, which can prevent the dust generated during grinding from flying everywhere. Then, the dust box 16 can be used to absorb the dust generated during grinding through the dust suction pipe 15, and the dust box 16 is a prior art. The dust box 16 can temporarily store dust to avoid the impact of dust on the environment, thereby improving the practicality of the device during use.
