Description

Technical Field

[0001] This utility model belongs to the field of building tools technology, and specifically relates to a connector for a putty scraper. Background Technology

[0002] Putty powder is a type of building decoration material. Its main components are talcum powder and glue. Workers usually use a scraper to apply putty to the wall surface to remove unevenness and defects on the surface of the object being coated.

[0003] Traditional putty scrapers lack long handles, requiring workers to stand on a scaffold to apply putty to high areas of the wall. Therefore, some putty scrapers with long handles have appeared on the market, such as the combined scraper tool disclosed in Chinese Utility Model Patent CN 202221756538.1. This tool includes a scraper connecting frame, with a scraper mounting groove on one side for engaging the scraper. A Y-shaped support frame is hinged to the lower part of the other side of the scraper connecting frame, and a latch is hinged to the upper part of the other side of the scraper connecting frame. The latch and the Y-shaped support frame are located on the same side of the scraper connecting frame. A first connecting seat is located at the lower part of the other side of the scraper connecting frame. The end faces of the first connecting seat are respectively provided with a first toothed surface and a second toothed surface. The first toothed surface and the second toothed surface on both sides of the first connecting seat are respectively... The device is equipped with a first tooth angle adjuster and a second tooth angle adjuster. An adjusting connector passes sequentially through one upper end of the Y-shaped support frame, the first tooth angle adjuster, the first connecting seat, the second tooth angle adjuster, and the other upper end of the Y-shaped support frame. The adjusting connector is then locked to connect the first connecting seat to the Y-shaped support frame. The adjusting connector includes a screw, one end of which is equipped with a knob, and the other end of which is detachably connected to a nut. The outer side of the third connecting seat is provided with a nut limiting groove, the size of which matches the nut.

[0004] In the above structure, the first tooth angle adjuster and the second tooth angle adjuster are controlled to press against the first tooth surface and the second tooth surface respectively by adjusting the connecting parts, so that the scraper connecting frame and the Y-shaped support frame are relatively fixed. However, during the use of this structure, the screw and nut are easy to loosen, which will cause the scraper connecting frame and the Y-shaped support frame to rotate unexpectedly, affecting the service life of the scraper tool.

[0017] The present invention is further configured such that: the cross-sectional size of the first positioning groove increases with the distance from the bottom of the first positioning groove, and the cross-sectional size of the first positioning part increases with the distance from the bottom of the first positioning groove.

[0018] The advantages of this utility model compared to the prior art are:

[0019] 1. In this utility model, the second positioning part can be disengaged from the second positioning groove by pressing the hinge, so that the extension rod can rotate relative to the connecting part. This makes it convenient for the user to adjust the relative angle between the extension rod and the connecting part, and is convenient for the user to use. In addition, the second positioning part is driven by the elastic element to maintain the cooperation between the second positioning part and the second positioning part during use. The second positioning part and the second positioning part are not easy to accidentally disengage during use, and the extension rod and the connecting part are prevented from rotating accidentally during use, making it convenient for the user to use.

[0020] 2. The detachable hinge shaft and positioning component in this utility model facilitate the disassembly and installation of the hinge component. Furthermore, the end cap and positioning component prevent the hinge component from detaching from the rotating hole, which is beneficial for the stable installation of the hinge component and prevents accidental detachment of the hinge component from the rotating hole during use, thus affecting the normal use of the putty scraper. The wear-resistant sleeve facilitates the flexible rotation of the hinge component and the rotating hole, reduces wear on the hinge component and the rotating hole during rotation, and extends the service life of the connector.

[0021] 3. The guide hole in this utility model facilitates the stable sliding of the hinge, preventing the hinge from tilting to the side during use and causing damage to the connector or extension rod, thus extending the service life of the connector. Since the end cap is slidably connected to the guide hole and the elastic element is hidden in the guide hole, it prevents debris from affecting the elongation and contraction of the elastic element during use, thus preventing damage to the elastic element and making it convenient for users. The setting of the limiting wall and the limiting protrusion can prevent the positioning element from disengaging from the first positioning groove, facilitating the stable installation of the hinge and the hinge shaft.

[0022] 4. The third positioning part and the third positioning groove in this utility model facilitate the positioning and installation of the hinge shaft and the positioning part, avoid the relative rotation of the hinge shaft and the positioning part during use, which would cause the connection between the hinge shaft and the positioning part to loosen, and prevent the hinge part from accidentally disengaging from the rotating hole and the first positioning groove, making it convenient for users to use; the setting of the connecting sleeve allows the manufacturer to increase the strength of the second positioning groove as needed, avoids excessive force on the connecting part during use which would cause damage to the second positioning groove, and helps to reduce the service life of the connector.

[0023] 5. The guide surface in this utility model facilitates the quick insertion of the first positioning part into the first positioning groove, and allows the user to quickly adjust the relative angle between the extension rod and the connector, making it convenient for the user. Since the cross-sectional size of the first positioning groove increases with the distance from the bottom of the first positioning groove, and the cross-sectional size of the first positioning part also increases with the distance from the bottom of the first positioning groove, it facilitates the quick connection and disconnection of the first positioning groove and the first positioning part. It can also reduce the friction between the first positioning groove and the first positioning part during the movement of the hinge, making it convenient for the user to control the hinge movement, and reducing the wear of the first positioning groove and the first positioning part after long-term use, thereby reducing or even avoiding the shaking of the extension rod and the connector during use.

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0036] See Figures 1 to 9 As shown, a connector for a putty scraper includes an extension rod 1. A connecting member 2 for mounting the putty scraper is rotatably mounted on the extension rod 1. The connecting member 2 is provided with a hinge seat 21. The hinge seat 21 is provided with a hinge 3 and an elastic member 4. The extension rod 1 is rotatably connected to the hinge seat 21 via the hinge 3. The hinge 3 is provided with a first positioning part 321 and a second positioning part 322. The hinge seat 21 is provided with a mounting hole 24 adapted to the hinge 3. The hinge 3 can slide axially along the mounting hole 24. A first positioning groove 25 is provided in the mounting hole 24. The first positioning part 321 is slidably mounted on the first positioning groove 25. In a positioning groove 25, the extension rod 1 is provided with a second positioning groove 15 that is adapted to the second positioning part 322. The second positioning part 322 and the second positioning groove 15 have multiple mounting positions. When the second positioning part 322 and the second positioning groove 15 are in different mounting positions, the relative angle between the extension rod 1 and the connecting member 2 is different. The elastic member 4 can drive the hinge member 3 to reset and make the second positioning part 322 cooperate with the second positioning groove 15. Under the action of external force, the hinge member 3 can slide axially along the mounting hole 24 and disengage the second positioning part 322 from the second positioning groove 15, so that the extension rod 1 can rotate relative to the connecting member 2.

[0037] In the above structure, pressing the hinge 3 can disengage the second positioning part 322 from the second positioning groove 15, allowing the extension rod 1 to rotate relative to the connecting part 2. This facilitates the user's adjustment of the relative angle between the extension rod 1 and the connecting part 2, making it convenient for the user to use. Furthermore, the elastic element 4 drives the second positioning part 322 to maintain its engagement with the second positioning element, preventing accidental disengagement of the second positioning part 322 from the second positioning element during use. This also prevents accidental rotation of the extension rod 1 and the connecting part 2 during use, making it convenient for the user to use.

[0038] In this embodiment, the hinge 3 is provided with a plurality of second positioning portions 322 on its outer periphery. The second positioning portions 322 are evenly distributed around the outer periphery of the hinge. The extension rod 1 is provided with a second positioning groove 15 that is adapted to each of the second positioning portions 322. After the extension rod 1 and the connector 2 are rotated at a certain angle, the second positioning portion 322 can cooperate with other second positioning grooves 15 and fix the extension rod 1 and the connector 2 relative to each other, thereby changing the relative angle between the extension rod 1 and the connector 2. In this embodiment, the mounting hole 24 is provided with a plurality of first positioning grooves 25 at intervals on its outer periphery. The first positioning grooves 25 extend axially along the mounting hole 24. The hinge 3 is provided with a first positioning portion 321 that is adapted to each of the first positioning grooves 25.

[0039] The connector 2 is provided with a fixing groove 22 for installing a putty scraper. The putty scraper can slide relative to the connector 22. A fixing buckle 23 is rotatably provided on the connector 2. The fixing buckle 23 abuts against the putty scraper and fixes the putty scraper in the fixing groove 22.

[0040] The hinge 3 described in this utility model includes a detachably connected hinge shaft 31 and a positioning member 32. The extension rod 1 is provided with a rotating hole that is rotatably connected to the hinge shaft 31. The first positioning part 321 and the second positioning part 322 are both provided on the positioning member 32. The hinge shaft 31 is provided with an end cap 311. The end cap 311 and the positioning member 32 are respectively provided on both sides of the rotating hole to prevent the hinge 3 from detaching from the rotating hole. The detachably connected hinge shaft 31 and positioning member 32 facilitate the disassembly and installation of the hinge 3. In addition, the end cap 311 and positioning member 32 prevent the hinge 3 from detaching from the rotating hole, which is conducive to the stable installation of the hinge 3 and avoids the hinge 3 from accidentally detaching from the rotating hole during use, thus affecting the normal use of the putty scraper.

[0041] Preferably, a wear-resistant sleeve 33 is fitted on the hinge shaft 31. The wear-resistant sleeve 33 passes through the rotation hole. The hinge 3 is rotatably connected to the extension rod 1 through the wear-resistant sleeve 33. The setting of the wear-resistant sleeve 33 is conducive to the flexible rotation of the hinge 3 and the rotation hole, which helps to reduce the wear of the hinge 3 and the rotation hole during the rotation process and helps to extend the service life of the connector.

[0042] The connector 2 is provided with two hinge seats 21, and a hinge groove 28 is formed between the two hinge seats 21. One end of the extension rod 1 is rotatably disposed in the hinge groove 28. One hinge seat 21 is provided with a mounting hole 24, and the other hinge 3 is provided with a guide hole 27. The hinge shaft 31 is slidably connected to the guide hole 27. One end of the elastic element 4 abuts against the end cap 311, and the other end of the elastic element 4 abuts against the extension rod 1 or the hinge seat 21. The setting of the guide hole 27 is conducive to the stable sliding of the hinge 3, and avoids the hinge 3 from tilting to the side during use, which would cause damage to the connector 2 or the extension rod 1, and helps to extend the service life of the connector.

[0043] In this embodiment, the end cap 311 is inserted into the guide hole 27 and slidably connected to the guide hole 27, and the elastic element 4 is hidden in the guide hole 27. This structure can prevent debris from affecting the elongation and contraction of the elastic element 4 during use, avoid damage to the elastic element 4, and facilitate user use.

[0044] In this utility model, a limiting protrusion 26 extends from the side wall of the mounting hole 24. A limiting wall 324 adapted to the limiting protrusion 26 is provided on the side of the first positioning part 321. The elastic member 4 drives the hinge member 3 to reset and makes the limiting wall 324 abut against the limiting protrusion 26. The setting of the limiting wall 324 and the limiting protrusion 26 can prevent the positioning member 32 from disengaging from the first positioning groove 25, which facilitates the stable installation of the hinge member 3 and the hinge shaft 31.

[0045] The positioning member 32 is provided with a third positioning groove 323, and the hinge shaft 31 is provided with a third positioning part 312 that is adapted to the third positioning groove 323. The third positioning part 312 and the third positioning groove 323 cooperate to restrict the relative rotation of the hinge shaft 31 and the positioning member 32. The setting of the third positioning part 312 and the third positioning groove 323 facilitates the positioning and installation of the hinge shaft 31 and the positioning member 32, avoids the relative rotation of the hinge shaft 31 and the positioning member 32 during use, which may cause the connection between the hinge shaft 31 and the positioning member 32 to become loose, and prevents the hinge member 3 from accidentally disengaging from the rotation hole and the first positioning groove 25, making it convenient for the user to use.

[0046] The extension rod 1 described in this utility model includes a connector 11, a positioning hole 12 is provided on the connector 11, a connecting sleeve 13 is detachably provided in the positioning hole 12, and a hinge hole 14 is provided in the connector 13. The hinge 3 is rotatably connected to the hinge hole 14, and a second positioning groove 15 is provided on the connecting sleeve 13 and located in or at one end of the hinge hole 14. The provision of the connecting sleeve 13 allows the manufacturer to increase the strength of the second positioning groove 15 as needed, avoids excessive force on the connector 2 during use, which would cause damage to the second positioning groove 15, and help reduce the service life of the connector.

[0047] In this embodiment, a fourth positioning groove 121 is provided on the side wall of the positioning hole 12, and a fourth positioning part 131 adapted to the fourth positioning groove 121 is provided on the connector 11.

[0048] The first positioning part 321 and / or the first positioning groove 25 are provided with a guide surface 151. The first positioning part 321 is guided into the first positioning groove 25 through the guide surface 151. The guide surface 151 facilitates the first positioning part 321 to quickly enter the first positioning groove 25, and facilitates the user to quickly adjust the relative angle between the extension rod 1 and the connector 2, making it convenient for the user to use. In this embodiment, both the first positioning part 321 and the first positioning groove 25 are provided with a guide surface 151.

[0049] In this invention, the cross-sectional size of the first positioning groove 25 increases with the distance from the bottom of the first positioning groove 25, and the cross-sectional size of the first positioning part 321 increases with the distance from the bottom of the first positioning groove 25. This structure facilitates the quick connection and disconnection of the first positioning groove 25 and the first positioning part 321, and can reduce the friction between the first positioning groove 25 and the first positioning part 321 during the movement of the hinge 3, making it easier for the user to control the hinge movement, and reducing the wear of the first positioning groove 25 and the first positioning part 321 after long-term use, thereby reducing or even preventing the extension rod 1 and the connector 2 from shaking during use.
