DETAILED DESCRIPTION

[0042] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. 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 implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0043] refer to Figure 1-4 A specific embodiment of the present invention provides a vibrating scraper, comprising:

[0044] Housing 1;

[0045] A blade 4, wherein the blade 4 is limited at a first end of the housing 1;

[0046] A vibration source, the vibration source is installed in the housing 1, and the housing 1 generates vibration through the vibration source;

[0047] The limiting unit is installed on the casing 1, and the blade 4 can be detached from the first end of the casing 1 through the limiting unit.

[0048] Currently on the market, for painted surfaces (coatings) and dirty tiles, a hand-held scraper is generally used to scrape off the paint (coating) and caulking agent (gap filler) on the surface. However, the hand-held scraper method is inconvenient, time-consuming, labor-intensive, and inefficient. In the present application, the main function of the limit unit is to install the blade 4 on the housing 1, which is convenient for holding the housing 1 and placing the blade 4 in the operating position; the main function of the vibration source is to generate vibration, and the housing 1 synchronously generates vibration through the vibration source, and the vibration is transmitted to the blade 4 through the housing 1, so that the blade 4 vibrates at a high frequency; when the blade 4 touches the painted surface and the excess, dry caulking agent, it can be easily scraped off. On the whole, the present application can reduce labor intensity, improve work efficiency, and bring convenience to construction.

[0049] Further optimization scheme, the limit unit includes:

[0050] A first limiting portion, the first limiting portion is installed in the housing 1, and the blade 4 is limited at a first end of the housing 1 by the first limiting portion;

[0051] The second limiting portion is installed outside the casing 1, and the first limiting portion is limited in the casing 1 through the second limiting portion.

[0052] The main function of the first limiting portion is to limit the blade 4 at the first end of the casing 1, which helps to ensure that the blade 4 is securely installed and in a stable state during use; the main function of the second limiting portion is to limit the first limiting portion to prevent the first limiting portion from loosening during use, that is, during continuous vibration, thereby affecting the installation stability of the blade 4.

[0053] Further optimizing the solution, the first limiting part includes:

[0054] An L-shaped limiting link 7, the short side of which passes through the blade 4 and clamps the blade 4 at the first end of the housing 1;

[0055] The connecting rod limiting handle 8 has a first end which is rotatably connected to the long side of the L-shaped limiting connecting rod 7 and is slidably connected in the casing 1 along the long side of the L-shaped limiting connecting rod 7, and a second end of the connecting rod limiting handle 8 is limited in the casing 1 by a second limiting portion.

[0056] After the short side of the L-shaped limit link 7 passes through the blade 4, the short side of the L-shaped limit link 7 is pulled to abut the blade 4 against the first end face of the casing 1, and the long side of the L-shaped limit link 7 is limited by the link limit handle 8, and the link limit handle 8 is limited in the casing 1 by the second limiting portion. With this arrangement, the blade 4 is limited at the first end of the casing 1 by the L-shaped limit link 7, the link limit handle 8, and the second limiting portion.

[0057] Further optimization plans also include:

[0058] A limiting protrusion 5, which is fixedly connected to the first end of the housing 1;

[0059] The strip hole 6 is opened on the blade 4 , the limiting protrusion 5 is adapted at the first end of the strip hole 6 , and the short side of the L-shaped limiting connecting rod 7 passes through the second end of the strip hole 6 .

[0060] The main function of the limiting protrusion 5 is to support the blade 4, further limit the blade 4, and fully ensure the installation stability of the blade 4.

[0061] Further optimization plans also include:

[0062] A rotating shaft 15, the rotating shaft 15 passes through the first end of the connecting rod limiting handle 8 and the long side of the L-shaped limiting connecting rod 7;

[0063] The two groups of oblong holes 17 are oppositely opened in the housing 1 and are arranged along the long side of the L-shaped limiting connecting rod 7 . The two ends of the rotating shaft 15 slide in the two groups of oblong holes 17 respectively.

[0064] An oblong hole 17 is provided, and by holding the connecting rod limit handle 8 and the L-shaped limit connecting rod 7, the rotating shaft 15 can be driven to slide in the oblong hole 17, so that the short side of the L-shaped limit connecting rod 7 can clamp the blade 4 on the housing 1 or release the blade 4. The connecting rod limit handle 8 can rotate around the rotating shaft 15 at a certain angle.

[0065] Further optimization plans also include:

[0066] A limit block 13, the limit block 13 is fixedly connected to the second end of the connecting rod limit handle 8;

[0067] A groove is provided on one side of the inner part of the housing 1, and the limit block 13 is fitted in the groove.

[0068] When the short side of the L-shaped limit link 7 passes through the blade 4, the limit block 13 enters the groove by pulling and turning the link limit handle 8. At this time, the short side of the L-shaped limit link 7 completes clamping the blade 4, and the rotating shaft 15 cannot continue to slide in the oblong hole 17. The limit block 13 is limited in the groove through the second limit part; at this time, the link limit handle 8 and the long side of the L-shaped limit link 7 are arranged in the same line.

[0069] Further optimizing the solution, the limit block 13 includes:

[0070] The first block 131 and the second block 132 are fixedly connected and are respectively fitted in the grooves along the axial direction of the rotating shaft 15 .

[0071] Further optimization scheme, the groove includes:

[0072] The first limiting groove 14 and the second limiting groove 16 are connected, the first limiting groove 14 and the second limiting groove 16 are connected, the first block 131 is adapted in the first limiting groove 14 , and the second block 132 is adapted in the second limiting groove 16 .

[0073] This arrangement prevents the connecting rod limit handle 8 and the limit block 13 from axially displacing along the rotating shaft 15, thereby ensuring the clamping position of the L-shaped limit connecting rod 7 and the blade 4, as well as the installation stability of the blade 4; wherein, the axial dimension of the second block 132 along the rotating shaft 15 is smaller than that of the first block 131, that is, the axial dimension of the second limit groove 16 along the rotating shaft 15 is smaller than that of the first limit groove 14.

[0074] Further optimizing the solution, the second limiting part includes:

[0075] The flip cover 2 has a first end that is rotatably connected to the outer wall of the casing 1 , and a second end that is clamped on the outer wall of the casing 1 and is in contact with the second end of the connecting rod limiting handle 8 .

[0076] By clamping the flip cover 2 on the outer wall of the casing 1, the purpose of limiting the limit block 13 in the groove is achieved; when the blade 4 needs to be replaced, the flip cover 2 is opened, and the second end of the connecting rod limiting handle 8 is rotated to the side away from the casing 1 to make the limit block 13 disengage from the groove. At this time, the connecting rod limiting handle 8 and the L-shaped limiting connecting rod 7 can be slid (achieved by the sliding of the rotating shaft 15 in the oblong hole 17), and the short side of the L-shaped limiting connecting rod 7 releases the blade 4, so that the blade 4 can be removed.

[0077] To further optimize the solution, the vibration sources include:

[0078] A motor 11, wherein the motor 11 is installed in the housing 1;

[0079] The eccentric wheel 12 is fixedly connected to the output shaft of the motor 11 .

[0080] After the motor 11 is started, the eccentric wheel 12 is driven to rotate, and vibration is generated while rotating, and the vibration is transmitted to the blade 4 through the housing 1.

[0081] Further optimization plans also include:

[0082] A battery 10, the battery 10 is installed in the housing 1;

[0083] A circuit board 9 is installed in the housing 1 and is electrically connected to the battery 10 and the motor 11;

[0084] The switch 3 is mounted on the outer wall of the housing 1 and is electrically connected to the circuit board 9 .

[0085] When the switch 3 is pressed, the motor 11 is powered on and vibrates, driving the front blade 4 to vibrate at high speed. The edge of the blade 4 quickly strikes the peeling paint surface (coating) and the tile caulking agent (gap filler), thereby removing the peeling paint surface and the dirty tile caulking agent.

[0086] According to the further optimization scheme, the total length of the application is controlled within 14 to 25 cm; the human-machine relationship is best within this length range; the outer dimensions of the hand-held part are controlled within 25 to 45 mm, and the human-machine relationship is best within this size range; the position of the switch 3 is controlled within 50 to 85 mm from the front end of the machine (i.e., the first end of the housing 1), and the human-machine relationship is best within this size range.
