DETAILED DESCRIPTION

[0031] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction to the technical solution of the present invention.

[0032] Example 1

[0033] like Figure 1 As shown, an internal and external wall decoration grinding device includes a fixed housing 10, a motor 20, a grinding head 30, an arc tube 40, a fan 50 and a limit mechanism 80. The fixed housing 10 is provided with the motor 20, the motor 20 is transmission-connected with the grinding head 30, and the grinding head 30 extends out of the fixed housing 10;

[0034] An arc tube 40 is provided inside the fixed housing 10 below the grinding head 30. A fan 50 is provided in the arc tube 40. When the fan 50 is working, the dust polished by the grinding head 30 is blown away to transport the dust from the grinding part.

[0035] A limiting mechanism 80 is provided on the fixed housing 10 at a position opposite to the grinding head 30 , and the limiting mechanism 80 supports the fixed housing 10 to fit against the wall.

[0036] Specifically, when performing a wall grinding operation, the limiting mechanism 80 assists in limiting the fixed housing 10 from being attached to the wall, which can reduce the user's strength when grinding the wall. At the same time, it can assist in limiting the overall position of the fixed housing 10 to maintain the movement stability of the grinding equipment during the grinding process. The motor 20 works to drive the grinding head 30 to rotate, and the grinding head 30 performs a grinding operation on the wall position that needs to be polished;

[0037] By providing the arc tube 40 and the fan 50, the dust produced by grinding can be collected in time, thereby avoiding the occurrence of large-scale dust in the grinding area, and achieving better practical application effects.

[0038] like Figure 2 As shown, the limiting mechanism 80 includes a fixed base 81, a first bull's eye ball 82, a telescopic rod 83 and a first rotating connecting card 84. The telescopic rod 83 is rotatably arranged on the top of the fixed base 81. The top of the telescopic rod 83 is connected to the fixed shell 10 through the first rotating connecting card 84. The first bull's eye balls 82 are evenly arranged on the bottom of the fixed base 81.

[0039] The telescopic rod 83 supports and limits the bottom of the fixed shell 10, reducing the force of the user holding the fixed shell 10, making the movement of the grinding device as a whole more labor-saving when grinding different parts of the wall. The bottom end of the telescopic rod 83 is rotatably set on the fixed base 81, and the first bull's eye ball 82 is evenly arranged on the bottom of the fixed base 81, which can make the movement of the grinding device as a whole more labor-saving and improve the wall grinding efficiency.

[0040] like Figure 2 As shown, a support member 85 is fixed on the top of the fixed base 81 on one side of the fixed shell 10, and the support member 85 controls the minimum tilt angle of the telescopic rod 83. The support member 85 includes an inclined fixing plate 851 and a support rod 852. The top of the support rod 852 is rotatably provided with an inclined fixing plate 851. Through the setting of the support member 85, the minimum tilt angle of the telescopic rod 83 can be limited. On the one hand, the overall grinding range of the grinding mechanism can be limited, and the grinding operation can be carried out within a reasonable grinding range. On the other hand, when the telescopic rod 83 rotates suddenly, it can prevent the fixed shell 10 on the telescopic rod 83 from falling to the ground, thereby having a better protection effect on the fixed shell 10.

[0041] Example 2

[0042] like Figure 2 As shown, an internal and external wall decoration grinding device includes a fixed housing 10, a motor 20, a grinding head 30, an arc tube 40, a fan 50 and a limit mechanism 80. The fixed housing 10 is provided with the motor 20, the motor 20 is transmission-connected with the grinding head 30, and the grinding head 30 extends out of the fixed housing 10;

[0043] An arc tube 40 is provided inside the fixed housing 10 below the grinding head 30. A fan 50 is provided in the arc tube 40. When the fan 50 is working, the dust polished by the grinding head 30 is blown away to transport the dust from the grinding part.

[0044] A limiting mechanism 80 is provided on the fixed housing 10 at a position opposite to the grinding head 30 , and the limiting mechanism 80 supports the fixed housing 10 to fit against the wall.

[0045] like Figure 4 As shown, the limiting mechanism 80 includes a right-angle fixed seat 801, a second bull's eye ball 802, a self-locking wheel 803, a fixed folding rod 804 and a second rotating connecting card 805. The self-locking wheel 803 is fixed to the bottom of the right-angle fixed seat 801, and the second bull's eye ball 802 is evenly arranged on the side of the right-angle fixed seat 801. A fixed folding rod 804 is fixed at the top corner of the right-angle fixed seat 801, and the top of the fixed folding rod 804 is connected to the fixed housing 10 through the second rotating connecting card 805;

[0046] When the limiting mechanism 80 is in use, the right-angle fixing seat 801 is located at the junction of the wall and the ground.

[0047] When grinding a wall, the right-angle fixing seat 801 is set at the junction of the wall and the bottom plate, so that the grinding device as a whole can move along the junction line between the wall and the bottom plate during the movement process, making the overall movement process more stable;

[0048] By setting the fixed folding rod 804, the fixed housing 10 can be supported. At the same time, the fixed folding rod 804 can be bent to change the direction to maintain the supporting effect for the fixed housing 10. Through this setting, the wall at the same horizontal position can be quickly polished, further improving the polishing efficiency.

[0049] Second bull's eye balls 802 are evenly arranged on the sides of the right angle fixing seat 801, so that when the right angle fixing seat 801 moves, a rolling connection is generated between the right angle fixing seat 801 and the wall, thereby reducing the friction resistance of the right angle fixing seat 801 and making the movement process smoother.

[0050] Example 3

[0051] On the basis of Example 1 or Example 2, Figure 5 As shown, a third bull's eye ball 902 is provided on the fixed housing 10 at one side of the grinding head 30 , and an elastic protective sleeve 901 is included on the fixed housing 10 at one side of the grinding head 30 .

[0052] A third bull's eye ball 902 is arranged on the fixed shell 10, so that when the grinding head 30 is grinding the wall, when the fixed shell 10 is moved, a rolling connection is maintained between the fixed shell 10 and the wall, so that the user can move the fixed shell 10 conveniently, thereby improving the overall grinding efficiency of the grinding equipment and achieving better practical application effect.

[0053] The fixed shell 10 includes an elastic protective sleeve 901 on one side of the grinding head 30. The elastic protective sleeve 901 can reduce dust generated by grinding when the grinding head 30 is grinding, and keep the environment around the grinding position clean.

[0054] Example 4

[0055] On the basis of Example 1 or Example 2, Figure 6 As shown, a dust guide 91 is provided on the fixed shell 10 at one side of the grinding head 30 , and a fixed bent rod 92 connected to the bottom of the dust guide 91 is fixed on the fixed shell 10 , and the dust guide 91 guides dust to the inside of the arc tube 40 .

[0056] like Figure 7As shown, the dust guide 91 includes an extraction plate 911, a rotating roller 912, a hollow plate 913 and a compression spring 914. One end of the hollow plate 913 is arranged on the fixed shell 10. The extraction plate 911 is slidably arranged inside the hollow plate 913. The hollow plate 913 is provided with an compression spring 914 connected to the extraction plate 911. A rotating roller 912 is rotatably arranged on the outer end of the extraction plate 911, and the rotating roller 912 is arranged parallel to the extraction plate 911.

[0057] Specifically, when the grinding head 30 is grinding the wall, the extrusion spring 914 in the hollow plate 913 will squeeze the plug-in plate 911, so that the rotating roller 912 on the plug-in plate 911 will contact the wall, and the dust will be guided by the plug-in plate 911 and the hollow plate 913, so that the dust will quickly enter the arc tube 40, and then the fan 50 will work to discharge the dust in the arc tube 40 in time.

[0058] like Figure 7 As shown, a slot is provided at the end of the insertion plate 911 for the rotating roller 912 to rotate, and a rotating shaft for rotatably connecting the rotating roller 912 is provided at the slot position on the insertion plate 911. Through this structural setting, when the fixed shell 10 is moving, the rotating roller 912 can assist in guiding the fixed shell 10 to move in the vertical direction, thereby maintaining the stability of the movement of the fixed shell 10.

[0059] like Figure 1 and Figure 3 As shown, a connecting hose 60 is connected to the bottom end of the arc tube 40 , and an end of the connecting hose 60 is connected to a collecting bag 70 .

[0060] With this structural arrangement, the collecting bag 70 can be placed at any position, so that the collected dust can be stored centrally without affecting the overall use of the grinding equipment.

[0061] like Figure 1 As shown, an operating handle 11 is fixed on the fixed shell 10 at one side of the limiting mechanism 80, and the operating handle 11 is arranged as an arc structure. Through the arrangement of the operating handle 11, the user can conveniently control the fixed shell 10 when performing the grinding operation.

[0062] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
