Description

Technical Field

[0001] This invention relates to the field of scraper technology, and in particular to a vibrating scraper. Background Technology

[0002] Most paint scrapers on the market are still simple designs with ordinary handles and blades, or with added devices that allow the entire blade to be detached. Moreover, these types of paint scrapers can only be used to scrape off paint and grout by manual force. However, using a hand scraper is very inconvenient, time-consuming, laborious, and inefficient.

[0003] Therefore, there is an urgent need for a vibratory scraper that can reduce labor intensity, improve work efficiency, and facilitate construction. Summary of the Invention

[0004] The purpose of this invention is to provide a vibratory scraper that solves the problems of time-consuming, labor-intensive, and inefficient techniques in the prior art. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The present invention provides a vibrating scraper, comprising:

[0007] chassis;

[0008] A blade, the blade being positioned at a first end of the housing;

[0009] A vibration source is installed inside the housing, and the housing vibrates through the vibration source;

[0010] A limiting unit is installed on the housing, and the blade is detachable from the first end of the housing via the limiting unit.

[0011] Preferably, the limiting unit includes:

[0019] A strip-shaped hole is formed on the blade, the limiting protrusion is adapted to the first end of the strip-shaped hole, and the short side of the L-shaped limiting link passes through the second end of the strip-shaped hole.

[0020] Preferred options also include:

[0021] A rotating shaft passes through the first end of the connecting rod limiting handle and the long side of the L-shaped limiting connecting rod;

[0022] Two sets of elongated holes are respectively opened in the housing and arranged along the long side of the L-shaped limiting link. The two ends of the rotating shaft slide in the two sets of elongated holes respectively.

[0023] Preferred options also include:

[0024] A limiting block, wherein the limiting block is fixedly connected to the second end of the connecting rod limiting handle;

[0025] A groove is formed inside one side of the housing, and the limiting block is adapted to fit within the groove.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

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

[0044] Casing 1;

[0045] Blade 4 is positioned at the first end of housing 1;

[0046] A vibration source is installed inside the housing 1, and the housing 1 generates vibration through the vibration source.

[0047] A limiting unit is installed on the housing 1, and the blade 4 is detachably attached to the first end of the housing 1 via the limiting unit.

[0048] Currently, for painted surfaces (coatings) and dirty tiles, a hand scraper is typically used to remove the paint (coating) and grout (grout filler). However, this method is inconvenient, time-consuming, labor-intensive, and inefficient. In this application, the limiting unit's main function is to mount the blade 4 onto the housing 1, facilitating handheld operation and positioning the blade 4 in the ready-to-operate position. The vibration source's main function is to generate vibration; the housing 1 synchronously generates vibration through the vibration source, transmitting the vibration to the blade 4, causing it to vibrate at a high frequency. When the blade 4 touches the painted surface and excess, dried grout, it can be easily scraped off. Overall, this application reduces labor intensity, improves work efficiency, and facilitates construction.

[0049] The solution has been further optimized, and the limiting unit includes:

[0050] The first limiting part is installed inside the housing 1, and the blade 4 is limited at the first end of the housing 1 by the first limiting part;

[0051] The second limiting part is installed outside the housing 1, and the first limiting part is limited inside the housing 1 by the second limiting part.

[0052] The main function of the first limiting part is to limit the blade 4 to the first end of the housing 1, which helps to ensure that the blade 4 is securely installed and stable during use. The main function of the second limiting part is to restrict the first limiting part and prevent the first limiting part from loosening during use, i.e., during continuous vibration, which would affect the installation stability of the blade 4.

[0053] The design has been further optimized, and the first limiting part includes:

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

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

[0056] After the short side of the L-shaped limiting link 7 passes through the blade 4, by pulling the link limiting handle 8, the short side of the L-shaped limiting link 7 abuts the blade 4 against the first end face of the housing 1. The long side of the L-shaped limiting link 7 is limited by the link limiting handle 8, and the link limiting handle 8 is limited inside the housing 1 by the second limiting part. In this way, the purpose of limiting the blade 4 to the first end of the housing 1 by the L-shaped limiting link 7, the link limiting handle 8, and the second limiting part is achieved.

[0057] Further optimizations to the plan include:

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

[0059] A slotted hole 6 is formed on the blade 4. A limiting protrusion 5 is fitted at the first end of the slotted hole 6. The short side of the L-shaped limiting link 7 passes through the second end of the slotted hole 6.

[0060] The main function of the limiting protrusion 5 is to further limit the blade 4 when it is held in place, thus ensuring the installation stability of the blade 4.

[0061] Further optimizations to the plan include:

[0062] 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] Two sets of elongated holes 17 are respectively opened in the housing 1 and arranged along the long side of the L-shaped limiting link 7. The two ends of the rotating shaft 15 slide in the two sets of elongated holes 17 respectively.

[0064] An elongated hole 17 is provided. By holding the connecting rod limiting handle 8 and the L-shaped limiting connecting rod 7, the rotating shaft 15 can be driven to slide within the elongated hole 17, thereby satisfying the requirement that the short side of the L-shaped limiting connecting rod 7 clamps the blade 4 onto the housing 1 or releases the blade 4. The connecting rod limiting handle 8 can rotate around the rotating shaft 15 by a certain angle.

[0065] Further optimizations to the plan include:

[0066] Limiting block 13 is fixedly connected to the second end of the connecting rod limiting handle 8;

[0067] The groove is formed inside the casing 1 on one side, and the limiting block 13 is adapted to fit in the groove.

[0068] When the short side of the L-shaped limiting link 7 passes through the blade 4, the limiting block 13 is moved into the groove by pulling and rotating the link limiting handle 8. At this time, the short side of the L-shaped limiting link 7 clamps the blade 4, and the rotating shaft 15 can no longer slide in the elongated hole 17. The limiting block 13 is limited in the groove by the second limiting part. At this time, the link limiting handle 8 and the long side of the L-shaped limiting link 7 are collinear.

[0069] Further optimization of the scheme, limit block 13 includes:

[0070] The first block 131 and the second block 132 are fixedly connected and are respectively adapted to the groove along the axial direction of the rotating shaft 15.

[0071] Further optimization of the design, the groove includes:

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

[0073] This configuration prevents the connecting rod limiting handle 8 and the limiting block 13 from shifting axially along the rotating shaft 15, ensuring the clamping position of the L-shaped limiting connecting rod 7 and the blade 4, as well as the installation stability of the blade 4. The second block 132 has a smaller axial dimension along the rotating shaft 15 than the first block 131, meaning the second limiting groove 16 has a smaller axial dimension along the rotating shaft 15 than the first limiting groove 14.

[0074] The design has been further optimized, and the second limiting part includes:

[0075] The flip cover 2 has its first end rotatably connected to the outer wall of the housing 1, and its second end is snapped onto the outer wall of the housing 1 and is in contact with the second end of the connecting rod limiting handle 8.

[0076] By attaching the flip cover 2 to the outer wall of the housing 1, the limiting block 13 is positioned within the groove. 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 away from the housing 1 to disengage the limiting block 13 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 sliding the rotating shaft 15 within the elongated hole 17). The short side of the L-shaped limiting connecting rod 7 releases the blade 4, allowing the blade 4 to be removed.

[0077] Further optimization of the scheme, vibration sources include:

[0078] Motor 11, motor 11 is installed inside housing 1;

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

[0080] After starting the motor 11, it drives the eccentric wheel 12 to rotate. The rotation generates vibration, which is transmitted to the blade 4 through the housing 1.

[0081] Further optimizations to the plan include:

[0082] Battery 10 is installed inside housing 1;

[0083] Circuit board 9 is installed inside the housing 1 and is electrically connected to the battery 10 and the motor 11.

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

[0085] Pressing switch 3 activates motor 11, causing it to vibrate and drive the front blade 4 to vibrate at high speed. The blade 4 quickly strikes the peeling paint (coating) and tile grout (gap filler), thus removing the peeling paint and dirty tile grout.

[0086] Further optimization of the design: the total length of this application is controlled within 14 to 25 cm; this length range provides the best human-machine interface; the dimensions of the hand grip are controlled within 25 to 45 mm; this size range provides the best human-machine interface; the position of switch 3 is controlled within 50 to 85 mm from the front end of the machine (i.e., the first end of the casing 1); this size range provides the best human-machine interface.
