Description

Technical Field

[0001] This utility model belongs to the field of manual tool technology, specifically relating to a scraper connector, which is particularly used for installing and connecting scrapers used for interior decoration, thereby increasing the operable area for construction workers. Background Technology

[0002] Applying putty is one of the methods of interior wall decoration. Putty is applied to the wall to ensure a smooth surface. Applying putty refers to removing uneven parts of the base surface through filling or overall treatment, keeping the wall smooth and flat. It is the most important step in base surface treatment.

[0003] Currently, putty application is generally done with a scraper. However, due to the large area of ​​walls, especially their height and width, a handle is usually added to the scraper to increase the work area for the worker. This allows the worker to expand the work area without moving. The handle and the scraper are connected by a connector. However, because different brands of scrapers, even those of the same specifications, may have different dimensions, the connectors are not universally compatible. Utility Model Content

[0004] This invention addresses the shortcomings of existing connectors in terms of poor versatility by providing a scraper connector that can be adjusted to accommodate different brands of scrapers, thereby improving the versatility of the scraper connector.

[0005] To achieve the above objectives, the scraper connector of this utility model includes: Base; The first and second grippers, which are disposed on the base and arranged facing each other, form a clamping space between the base, the first gripper, and the second gripper. The internal width of the clamping space is greater than the open width of the clamping space. An adjustment mechanism is provided at the base, which has a handle that switches between a clamping position and a releasing position. When the handle is in the clamping position, the clamping space is reduced, and when the handle is in the releasing position, the clamping space is expanded.

[0006] Therefore, even if different scrapers have different sizes, the scraper can be installed on the connecting seat through the clamping space that can be expanded and reduced. The scraper is clamped in the clamping space by the adjustment mechanism, and the scraper can be loosened or tightened by the operating handle. It has good versatility and is easy to use.

[0007] In one embodiment, the first and second grippers are integrally connected to the base. The adjustment mechanism includes a cam disposed on a handle that is flipped and fitted to the base. When the handle flips from a released position to a clamping position, the cam moves into the clamping space to reduce the clamping space; when the handle flips from the clamping position to a released position, the cam moves away from the clamping space to expand the clamping space. This embodiment's structure maintains a fixed distance between the first and second grippers and provides high strength, making it suitable for using the cam to apply a reliable clamping force to the scraper to securely mount the scraper to the connecting seat. This type of connecting seat is particularly suitable for connecting scrapers of the same specifications but with slight dimensional differences.

[0008] Preferably, to prevent the scraper from moving in the connecting seat during use, the adjustment mechanism consists of at least two spaced-apart adjustment mechanisms, so that the scraper is clamped by cams at at least two locations, preventing uneven force on the scraper during operation and causing it to shake in the connecting seat.

[0009] Preferably, to maintain a permanent grip on the scraper and prevent it from loosening, the handle is self-locking via a cam when in the gripped position. This prevents the handle from accidentally flipping over and releasing the scraper.

[0010] In another embodiment, the first gripper is integrally connected to the base, and the second gripper is rotatably connected to the base. The adjustment mechanism includes a connecting rod connecting the handle and the second gripper. The handle is flipped and assembled to the base. When the handle flips from the released position to the clamping position, the second gripper is brought closer to the first gripper by the connecting rod to reduce the clamping space. When the handle flips from the clamping position to the released position, the second gripper is brought away from the first gripper by the connecting rod to expand the clamping space. This connecting seat structure utilizes the variable distance between the first and second grippers to increase the clamping space and relies on the clamping force of the first and second grippers to clamp the scraper. It is suitable for connecting scrapers of different specifications or with large dimensional errors to the connecting seat, and can more conveniently place or remove the scraper from the clamping space.

[0011] Preferably, to maintain a persistent clamping of the scraper and prevent it from loosening, the handle is self-locking due to the torque applied to the handle by the connecting rod when it is in the clamping position. This prevents the handle from accidentally flipping over and releasing the scraper.

[0012] Preferably, to prevent the scraper from wobbling relative to the connecting seat, at least one of the base, the first clamping jaw, and the second clamping jaw has an anti-slip component attached to its surface facing the clamping space. This anti-slip component contacts the scraper when it is connected to the connecting seat, increasing friction and preventing uneven force on the scraper during operation that could cause wobbling.

[0013] Preferably, the base is rotatably connected to the handle via a horizontal axis. This allows the connecting seat and the scraper to rotate relative to the handle to adjust their posture, making it more comfortable for construction workers to operate.

[0014] Preferably, the base and the handle are engaged by an anti-rotation surface. This is used to maintain the relative posture of the connecting seat and the handle.

[0015] Preferably, the horizontal shaft is locked in place by a threaded connection to prevent rotation. This allows for easy tightening or loosening of the connecting seat and handle via the thread, facilitating adjustment of their relative positions.

[0016] This invention features a first and second gripper arranged opposite each other at the base, forming a clamping space. An adjustment mechanism including a handle is also provided at the base. The handle rotates between a clamping position and a releasing position; when the handle is in the clamping position, the clamping space is reduced; when the handle is in the releasing position, the clamping space is expanded. Therefore, even with different sizes of scrapers, the scraper can be installed on the connecting seat through the expandable and retractable clamping space. The scraper is clamped in the clamping space by the adjustment mechanism, and the scraper is released or tightened by operating the handle. This design offers good versatility and ease of use.

[0020] In the description of this utility model, it should be understood that the technical features defined by terms such as "first" and "second" which have a sequential concept are only for the purpose of clearly describing the defined technical features and making the defined technical features clearly distinguishable from other technical features, and do not represent that they are named in this way in actual implementation. Therefore, they should not be construed as limitations on this utility model.

[0021] The present invention will now be described in detail with reference to specific embodiments and accompanying drawings.

[0022] Example 1 like Figure 1-7 As shown, the scraper connector includes a base 100, a first gripper 200, a second gripper 300, and an adjustment mechanism 500.

[0023] The base 100 is in the form of a slightly curved plate, which serves as the base of the entire connector and is also used to connect to the handle 700.

[0024] The first gripper 200 and the second gripper 300 are disposed on the base 100 and arranged facing each other, forming a clamping space 400 between the base 100, the first gripper 200, and the second gripper 300. The first gripper 200 and the second gripper 300 are curved such that the internal width of the clamping space 400 is greater than the open width of the clamping space (in... Figure 5-7 In the middle, the width direction is the direction of the line connecting the edge of the first gripper 200 and the edge of the second gripper 300, so that the scraper can be connected and constrained in the clamping space by the first gripper and the second gripper.

[0025] Adjustment mechanism 500 is disposed on base 100, and is provided with Figure 6 The clamping position shown is the same as Figure 7 The handle 501, which is switched between the release positions shown, reduces the clamping space 400 when the handle 501 is in the clamping position and expands the clamping space 400 when the handle 501 is in the release position.

[0026] Therefore, even if different scrapers vary in size, they can all be installed and configured on the connecting seat through the expandable and retractable clamping space, and the scraper is clamped in the clamping space by the adjustment mechanism. The scraper is loosened or tightened by the operating handle, realizing disassembly or installation, which is versatile and convenient to use.

[0027] In this embodiment, the first gripper 200 and the second gripper 300 are integrally connected to the base 100. The adjusting mechanism 500 includes a cam 502 disposed on a handle 501, which is flipped and mounted to the base 100 via a first pin 504. The handle 501 moves from... Figure 7 The release position is shown. Figure 6 When the clamping position is flipped, the cam 502 moves toward the clamping space 400 to reduce the clamping space, and the handle 501 moves from... Figure 6 The clamping position shown is towards Figure 7 When the release position is flipped as shown, cam 502 moves away from clamping space 400 to expand the clamping space.

[0028] The reduction and expansion of the clamping space 400 Figure 6 , Figure 7 The difference is reflected in the height of the clamping space (the distance between the cam and the opening), as in shank 501. Figure 6 As shown, when in the clamping position, the height H1 of the clamping space is less than the handle 501. Figure 7 The height H2 of the clamping space is shown when the device is in the released position.

[0029] The structure of this embodiment maintains a fixed distance between the first and second grippers and possesses high strength, making it suitable for using a cam to apply a reliable holding force to the scraper to securely mount the scraper to the connector. This type of connector is particularly suitable for connecting scrapers of the same specifications but with slight dimensional differences.

[0030] In this embodiment, to prevent the scraper from moving within the connecting seat during use, the adjusting mechanism 500 consists of two spaced-apart units, thereby clamping the scraper with cams at at least two locations and preventing uneven force on the scraper during operation, which could cause it to wobble within the connecting seat. In other embodiments, the adjusting mechanism may consist of multiple spaced-apart units.

[0031] In this embodiment, in order to maintain a permanent grip on the scraper and prevent it from loosening, the handle 501 is located at... Figure 6 The clamping position shown relies on cam 502 for self-locking to prevent the handle from accidentally flipping and releasing the scraper. Specifically, as... Figure 6 As shown, when the handle 501 is in the clamping position, it clamps the scraper. The cam 502 squeezes the scraper and receives a reaction force F1 from the scraper. This reaction force F1... Figure 6 The upward-pointing arrow indicates that the reaction force F1 generates a clockwise torque on the handle around the first pin 504, causing the handle to press against the base 100 and achieving handle self-locking.

[0032] In this embodiment, the base 100 is rotatably connected to the handle 700 via a horizontal axis 800, only a portion of which is shown in the figure. This allows the connecting seat and scraper to rotate relative to the handle to adjust their posture, making it more comfortable for construction workers to operate. Furthermore, the base 100 and the handle 700 engage with a toothed anti-rotation surface 101 to maintain the relative posture of the connecting seat and the handle. The horizontal axis 800 is threaded to lock the anti-rotation surface. Specifically, the horizontal axis 800 is a bolt with a wing nut 801 connected to it; the base and handle are locked or loosened by tightening the wing nut 801. This facilitates locking or loosening the connecting seat and handle via threads, and facilitates adjustment of their relative posture.

[0033] Example 2 like Figure 8-14 As shown, the scraper connector also includes a base 100, a first gripper 200, a second gripper 300, and an adjustment mechanism 500.

[0034] The base 100 is in the form of a slightly curved plate, which serves as the base of the entire connector and is also used to connect to the handle 700.

[0035] The first gripper 200 and the second gripper 300 are disposed on the base 100 and arranged facing each other, forming a clamping space 400 between the base 100, the first gripper 200, and the second gripper 300. The first gripper 200 and the second gripper 300 are curved such that the internal width of the clamping space 400 is greater than the open width of the clamping space (in... Figure 12-14 In the middle, the width direction is the direction of the line connecting the edge of the first gripper 200 and the edge of the second gripper 300, so that the scraper can be connected and constrained in the clamping space by the first gripper and the second gripper.

[0036] Adjustment mechanism 500 is disposed on base 100, and is provided with Figure 13 The clamping position shown is the same as Figure 14 The handle 501, which is switched between the release positions shown, reduces the clamping space 400 when the handle 501 is in the clamping position and expands the clamping space 400 when the handle 501 is in the release position.

[0037] Therefore, even if different scrapers have different sizes, the scraper can be installed on the connecting seat through the clamping space that can be expanded and reduced. The scraper is clamped in the clamping space by the adjustment mechanism, and the scraper can be loosened or tightened by the operating handle. It has good versatility and is easy to use.

[0038] In this embodiment, the first gripper 200 is integrally connected to the base 100, and the second gripper 300 is rotatably connected to the base 100 via a second pin 505. The adjusting mechanism 500 includes a connecting rod 503 connecting the handle 501 and the second gripper 300. The handle 501 is flipped and assembled to the base 100 via a first pin 504. The handle 501 can be adjusted from... Figure 14 The release position is shown. Figure 13 When the clamping position is flipped as shown, the second gripper 300 is brought closer to the first gripper 200 by the connecting rod 503 to reduce the clamping space 400, and the handle 501 moves from... Figure 13 The clamping position shown is towards Figure 14 When the release position is flipped as shown, the second gripper 300 is carried away from the first gripper 200 by the connecting rod 503 to expand the gripping space 400.

[0039] The reduction and expansion of the clamping space 400 Figure 13 , Figure 14 The difference is reflected in the opening width, such as the handle 501. Figure 13 The opening width W1 shown when in the clamping position is less than that of the handle. Figure 14 The opening width W2 is shown when the device is in the loosened position.

[0040] The connecting seat of this structure uses the variable spacing between the first and second jaws to increase the range of the clamping space, and relies on the clamping force of the first and second jaws to clamp the scraper. It is suitable for connecting scrapers of different specifications or with large dimensional errors to the connecting seat, and can more conveniently place the scraper in the clamping space or remove it from the clamping space.

[0041] In this embodiment, in order to maintain a permanent grip on the scraper and prevent it from loosening, the handle 501 is located at... Figure 13 In the clamping position shown, the torque applied to the handle 501 by the connecting rod 503 provides self-locking, preventing the handle from accidentally flipping and releasing the scraper. Specifically, as... Figure 13 As shown, when the handle 501 is in the clamping position, it clamps the scraper. The connecting rod 503 is supported between the handle 501 and the second jaw 300 and applies a pushing force F2 to the handle. This pushing force F2 is... Figure 13 The right-pointing arrow indicates that the thrust F2 generates a counterclockwise torque on the handle around the first pin 504, causing the handle to press against the base 100 and achieve handle self-locking.

[0042] In this embodiment, to prevent the scraper from wobbling relative to the connecting seat, at least one of the base 100, the first gripper 200, and the second gripper 300 is provided with an anti-slip component 600 on its surface facing the clamping space. This anti-slip component contacts the scraper when it is connected to the connecting seat, increasing friction and preventing uneven force on the scraper during operation that could cause wobbling.

[0043] In this embodiment, the base 100 is rotatably connected to the handle 700 via a horizontal axis 800, only a portion of which is shown in the figure. This allows the connecting seat and scraper to rotate relative to the handle to adjust their posture, making it more comfortable for construction workers to operate. Furthermore, the base 100 and the handle 700 engage with a toothed anti-rotation surface 101 to maintain the relative posture of the connecting seat and the handle. The horizontal axis 800 is threadedly connected to lock the anti-rotation surface. Specifically, the horizontal axis 800 is a bolt with a head 802, and a nut is connected to the bolt. Tightening or loosening the head 802 locks or loosens the base and handle. This facilitates tightening or loosening the connecting seat and handle via threads, and facilitates adjustment of their relative posture.
