Description

Technical Field

[0001] The utility model relates to the technical field of scraping therapy, and particularly relates to a scraping instrument. Background Art

[0002] Scraping therapy is a physical therapy method. By applying scraping, dotting, picking, hitting and other techniques with a scraping tool on specific areas of the body, it can cause the skin to show flushing, ecchymosis and other scraping marks, aiming to dredge the meridians and detoxify and arouse the spirit. As a key tool, there are various types of scraping boards, but most of them are basic types. To improve the use experience, especially for specific areas such as the shoulders, the scraping board is designed with an adjustable angle between the handle and the scraping head. However, the existing adjustable structures often face the problem of unstable connection between the handle and the scraping head. Content of the Utility Model

[0003] The purpose of the utility model is to provide a scraping instrument to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above technical problems:

[0005] The utility model provides a scraping instrument, which includes a scraping head and a handle. The scraping head is provided with a rotating shaft, the rotating shaft is a hollow rod, and the side wall of the rotating shaft is provided with a rotating hole and a clamping hole with an equilateral polygon cross-section; the handle is a hollow rod, an installation block is arranged inside the handle, the installation block is provided with a connecting groove, the rotating shaft is inserted into the connecting groove from the top of the handle, the installation block is provided with a rotating pin piece slidably arranged in the installation block along the radial direction of the rotating shaft, the side wall of the handle is clamped with a button cover, the rotating pin piece sequentially passes through the side wall of the connecting groove, the rotating hole, the clamping hole, the side wall of the connecting groove and is connected with the button cover, a clamping section adapted to the clamping hole is arranged in the middle of the rotating pin piece, at least two clamping grooves extending along the radial direction of the rotating pin piece are arranged on the side of the rotating shaft away from the button cover, the rotating pin piece is provided with a limiting block clamped with the clamping groove, and a first elastic member is arranged between the installation block and the button cover. The first elastic member provides an elastic force to drive the limiting block to be clamped with the clamping groove and the clamping section to be sleeved in the clamping hole.

[0006] The beneficial effects of the utility model are:

[0007] When adjusting the angle between the scraping head and the handle, hold the button cover, rotate the pin and slide it relative to the mounting block, push the limit block to disengage from the clamping groove, and at the same time the clamping section disengages from the clamping hole. At this time, the scraping head can be freely rotated. When it is rotated to the required angle, release the button cover. Under the action of the first elastic member, push the limit block to engage with the clamping groove and at the same time the clamping section engages with the clamping hole to lock the angle between the handle and the scraping head. Since the cross-section of the clamping hole is an equilateral polygon and the cross-section of the clamping section is also a corresponding equilateral polygon, the clamping section cannot rotate in the clamping hole. Therefore, when the clamping section is sleeved in the clamping hole, the angle between the handle and the scraping head can also be locked. The utility model sets two locking positions, one is that the limit block engages with the clamping groove, and the other is that the clamping section engages with the clamping hole, which has a better locking effect and the connection between the handle and the scraping head is more stable.

[0008] As a further improvement of the above technical solution, the cross-section of the clamping section gradually increases from the button cover to the limit block, the side surface of the clamping section is an inclined surface, and the inner side wall of the clamping hole is adapted to the clamping section.

[0009] When the clamping section just snaps into the clamping hole, its cross-section is slightly smaller than that of the clamping hole, which is beneficial for the clamping section to better snap into the clamping hole and play a guiding role. Especially when the clamping section and the clamping hole are not exactly corresponding, it plays a guiding and guiding role and is beneficial for the clamping section to better snap into the clamping hole.

[0010] As a further improvement of the above technical solution, the number of the limit blocks is two, and the two limit blocks are arranged on the same radial direction of the rotating pin. By setting two clamping positions, two symmetrical stress points are formed, making the structure more stable.

[0011] As a further improvement of the above technical solution, a rotating slot hole is provided at the top of the handle, and the rotating shaft extends out of the rotating slot hole and rotates along the rotating slot hole. The rotating slot hole can show the rotation direction of the scraping head, which is convenient for rotating the angle of the scraping head. The rotating slot hole can also play a guiding role.

[0012] As a further improvement of the above technical solution, a pressing hole is provided on the side wall of the handle, and the button cover is provided with an annular abutting edge that abuts against the edge of the pressing hole.

[0013] As a further improvement of the above technical solution, the button cover is provided with a limit slot for abutting against the mounting rotating pin, which is convenient for the rotating pin and also convenient for installing the elastic member.

[0014] As a further improvement of the above technical solution, the first elastic member is a first spring sleeved on the rotating pin member, which provides a fixed path and position for the first spring, preventing the first spring from shifting or twisting when subjected to pressure or tension. The first spring is directly sleeved on the rotating pin member, which can simplify the structure of the device, reduce the number and complexity of components. This not only reduces the manufacturing cost of the device, but also improves the assembly efficiency and maintainability of the device.

[0015] As a further improvement of the above technical solution, a second elastic member is provided between the limiting block and the side wall of the handle, and the second elastic member provides an elastic force for pushing the limiting block to be engaged with the engaging groove and the engaging section to be engaged with the engaging hole. Further providing elastic force plays a better engaging role, and the engaging and locking are more firm.

[0016] As a further improvement of the above technical solution, the second elastic member includes a second spring, and one end of the second spring is sleeved on the end of the rotating pin member. It is convenient to fix the second spring, so that the spring plays a role in providing elastic force and improves the stability of the overall device structure.

[0017] As a further improvement of the above technical solution, the mounting block is provided with a limiting channel for limiting the second spring. The limiting channel provides a fixed path and position for the second spring, preventing the second spring from shifting or twisting when subjected to pressure or tension. This stability ensures that the second spring can work in a predetermined direction and with a predetermined force, thereby improving the stability and reliability of the entire device or structure.

[0028] In the description of the present utility model, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0029] Referring to Figures 1 to 6 , the following embodiments are made for a scraping instrument of the present utility model:

[0030] A scraping instrument includes a scraping head 100 and a handle 200. The scraping head 100 is rotatably and fixedly arranged at the top of the handle 200. When scraping a specific part, the angle between the scraping part and the handle 200 can be adjusted, which is convenient for holding the handle 200 to perform scraping. When scraping, the handle 200 is more comfortable and fitting to hold, the wrist exerts force without getting tired, and one person can also complete scraping of parts such as the shoulder and neck.

[0031] The scraping head 100 is internally provided with a heating component, and this scraping instrument has an automatic heating function. Since the surface of the scraping head 100 needs to maintain a certain flatness and is generally made of bian stone, it is easily damaged when encountering external collisions. Therefore, the scraping head 100 is provided with a protective cover. The protective cover is sleeved on the scraping head 100, fits with the scraping head 100, and has a shape adapted to the scraping head 100, playing a role in protecting the scraping head 210. The protective cover is made of silicone material or other soft rubber materials. The silicone material is softer and can achieve a better protection effect. The handle 200 is internally provided with a power supply component, and the power supply component is electrically connected to the internal vibration motor and heating component. It is convenient to move and use the scraping instrument and is convenient to carry when going out. The scraping instrument of the present utility model has functions such as vibration, heating, adjustable massage angle, and convenient portability when going out.

[0032] Specifically, the following introduces how to fix the connection structure between the handle 200 and the scraping head 100.

[0033] A rotating shaft 110 is provided at the bottom of the scraping head 100. The rotating shaft 110 is a hollow rod. A rotating hole 111 is provided on the left side wall of the rotating shaft 110, and a clamping hole 112 with an equilateral polygon cross-section is provided on the left side wall of the rotating shaft 110. The equilateral polygon can be an equilateral octagon, an equilateral decagon, etc.

[0034] The handle 200 is a hollow rod. A rotating groove hole 210 is provided on the rear side wall of the top of the handle 200. An installation block 300 is provided inside the handle 200. The installation block 300 is provided with a connection groove 310. The rotating shaft 110 is inserted into the connection groove 310 from the rotating groove hole 210. The rotating shaft 110 can rotate back and forth in the connection groove 310. The installation block 300 is provided with a rotating pin 400 that slides left and right on the installation block 300. A button cover 500 is clamped and arranged on the left side wall of the handle 200. The rotating direction of the scraping head 100 can be seen through the rotating groove hole 210, which is convenient for adjusting the rotation angle of the scraping head 100, and the rotating groove hole 210 can also play a guiding role.

[0035] The rotating pin 400 sequentially passes through the side wall of the connection groove 310, the rotating hole 111, the clamping hole 112, the side wall of the connection groove 310 from right to left and is fixedly connected to the button cover 500. A clamping section 410 adapted to the clamping hole 112 is provided in the middle of the rotating pin 400. At least two clamping grooves 113 extending radially along the rotating pin 400 are provided on the right side wall of the rotating shaft 110. The rotating pin 400 is provided with two limiting blocks 420 that are clamped with the clamping grooves 113. Among them, the two limiting blocks 420 are arranged on the same radial direction of the rotating pin 400. Two clamping positions are set to form two symmetrical stress points, making the structure more stable. In some other embodiments, only one limiting block 420 can also be provided.

[0036] A first elastic member 600 is disposed between the mounting block 300 and the button cover 500. The first elastic member 600 includes a first spring which is sleeved on the rotating pin member 400, and its two ends are respectively in contact with the mounting block 300 and the button cover 500. The first elastic member 600 causes the rotating pin member 400 to move leftward, so that the limiting block 420 is engaged with the engaging groove 113 and at the same time the engaging section 410 is sleeved in the engaging hole 112.

[0037] The first spring is sleeved on the rotating pin member 400, providing a fixed path and position for the first spring, preventing the first spring from shifting or twisting when subjected to pressure or tension. The first spring is directly sleeved on the rotating pin member 400, which can simplify the structure of the device, reduce the number and complexity of components. This not only reduces the manufacturing cost of the device, but also improves the assembly efficiency and maintainability of the device.

[0038] When adjusting the angle between the scraping head 100 and the handle 200, hold the button cover 500, the rotating pin member 400 slides relative to the mounting block 300, pushing the limiting block 420 to disengage from the engaging groove 113, and at the same time the engaging section 410 disengages from the engaging hole 112. At this time, the scraping head 100 can be freely rotated. When it is rotated to the required angle, release the button cover 500. Under the action of the elastic member, the limiting block 420 is pushed to engage with the engaging groove 113 and at the same time the engaging section 410 engages with the engaging hole 112 to lock the angle between the handle 200 and the scraping head 100.

[0039] Since the cross-section of the engaging hole 112 is an equilateral polygon and the cross-section of the engaging section 410 is also a corresponding equilateral polygon, the engaging section 410 cannot rotate in the engaging hole 112. Therefore, when the engaging section 410 is sleeved in the engaging hole 112, the angle between the handle 200 and the scraping head 100 can also be locked.

[0040] The present utility model sets two locking positions. One is that the limiting block 420 is engaged with the engaging groove 113, and the other is that the engaging section 410 is engaged with the engaging hole 112, having a better locking effect and making the connection between the handle 200 and the scraping head 100 more stable.

[0041] For further improvement, refer to Figure 4, the cross-section of the clamping section 410 gradually increases from left to right, presenting a gradually changing shape. The side surface of the clamping section 410 is an inclined surface. This design enables the clamping section 410 to smoothly guide and adapt to the internal structure of the clamping hole 112 during the insertion process. The inner wall of the clamping hole 112 is adapted to the clamping section 410. The inner wall of the clamping hole 112 gradually contracts inward along the insertion path of the clamping section 410, and its inclination angle matches the inclined surface of the clamping section 410, thereby achieving a tight fit and a stable connection between the two. This design not only improves the reliability of the connection, realizes an efficient and stable connection between the two, but also ensures the stability and durability of the overall structure.

[0042] In addition, when the clamping section 410 is just inserted into the clamping hole 112, its cross-section is slightly smaller than that of the clamping hole 112, which is beneficial for the clamping section 410 to better engage with the clamping hole 112 and play a guiding role. Especially when the clamping section 410 and the clamping hole 112 are not exactly corresponding, it plays a guiding role and is beneficial for the clamping section 410 to better engage with the clamping hole 112. In some other embodiments, the cross-sections of the clamping sections 410 can be of the same size.

[0043] For further improvement, a pressing hole 220 is provided on the side wall of the handle 200, and the button cover 500 is provided with an annular abutting edge 510 that abuts against the edge of the pressing hole 220.

[0044] For further improvement, the button cover 500 is provided with an abutting groove 520, and the rotating pin 400 abuts against the abutting groove 520. When pressed, the rotating pin 400 can be more stably pushed to slide relative to the mounting block 300, and it is also convenient to install the elastic member. The first spring is sleeved on the rotating pin 400, and its two ends respectively abut against the bottom of the abutting groove 520 and the mounting block 300.

[0045] For further improvement, the first elastic member 600 is a first spring. The first spring is sleeved on the rotating pin 400. The rotating pin 400 provides a fixed path and position for the first spring, preventing the first spring from shifting or twisting when subjected to pressure or tension. The first spring is directly sleeved on the rotating pin 400, which can simplify the structure of the device, reduce the number and complexity of components. This not only reduces the manufacturing cost of the device, but also improves the assembly efficiency and maintainability of the device. In some other embodiments, the first elastic member 600 can be an elastic sheet.

[0046] For further improvement, referring to Figure 4 , a second elastic member 700 is provided between the limiting block 420 and the side wall of the handle 200. The second elastic member 700 provides an elastic force to push the limiting block 420 to engage with the clamping groove 113 and the clamping section 410 to engage with the clamping hole 112. Further providing an elastic force plays a better clamping role and makes the clamping and locking more firm.

[0047] The second elastic member 700 includes a second spring, and one end of the second spring is sleeved on the end of the rotating pin member 400. This facilitates the fixation of the second spring, enabling the spring to provide an elastic force and enhancing the stability of the overall device structure.

[0048] Furthermore, the mounting block 300 is provided with a limiting channel 320 for limiting the second spring. The limiting channel 320 provides a fixed path and position for the second spring, preventing the second spring from shifting or twisting when subjected to pressure or tension. This stability ensures that the second spring can operate in a predetermined direction and with a predetermined force, thereby enhancing the stability and reliability of the entire device or structure.

[0049] The above has specifically described the preferred embodiments of the present utility model, but the present invention is not limited to the embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present utility model, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
