Description

Technical Field

[0001] This utility model relates to the field of hand embroidery technology, and in particular to an embroidery frame support. Background Technology

[0002] An embroidery frame stand is a tool used to support and secure an embroidery frame, commonly used in hand embroidery. Its main function is to provide a stable working platform, allowing the embroiderer to perform embroidery operations more conveniently. Without a stand, the embroidery frame may wobble or move, affecting the quality and efficiency of the embroidery. Existing embroidery frame stands include an embroidery frame body with an embroidery frame clamp that holds the embroidery frame. For details, please refer to a convenient hand embroidery frame disclosed in patent application number 202221983765.8.

[0003] The existing technology has three shortcomings: (1) The clamp of the embroidery frame clamp is controlled by screws to open and close. When opening the clamp, the screws need to be loosened to loosen the clamp. However, due to gravity, the clamp will not open by itself, but must be manually pried open. This requires one hand to pry open the clamp and the other hand to control the embroidery frame to be fed into the clamp and adjusted. It is impossible to operate with one hand. (2) Since the embroidery frame clamp is fixed, the angle of the embroidery frame cannot be adjusted. Especially when reeling in the thread, the entire embroidery frame needs to be flipped over. The embroidery frame can only be removed from the embroidery frame support, flipped over and then reinstalled on the embroidery frame support before the thread can be reeled in. This operation is very cumbersome. (3) The embroidery frame support is fixed by clamping itself against the edge of the table with a U-shaped clamp. This fixing method restricts the opening direction of the clamp of the embroidery frame clamp. This is extremely inconvenient for users who are used to embroidering with their left hand or for situations where special stitches are required. Utility Model Content

[0004] The first technical problem to be solved by this utility model is to provide an embroidery frame bracket with an automatically opening clamp that allows the user to fix the embroidery frame with one hand, in light of the above-mentioned technical status.

[0005] The second technical problem to be solved by this utility model is to provide an embroidery frame support that can rotate, in response to the above-mentioned technical status quo.

[0006] The third technical problem to be solved by this utility model is to provide an embroidery frame support in view of the above-mentioned technical status quo, which allows the opening direction of the clamp of the embroidery frame clamp to be changed over a wide range.

[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: an embroidery frame support, including a vertically arranged support column and an embroidery frame clamp that can be opened and closed on the upper part of the support column, characterized in that: the embroidery frame clamp includes a pair of horizontally extending upper clamping body components and a lower clamping body component that can move relative to each other, and an adjusting screw that vertically passes through the upper clamping body components and the lower clamping body components.

[0008] The adjusting screw has an upper threaded section and a lower threaded section, with the upper threaded section and the lower threaded section having opposite helical directions. The upper clamping body assembly has an upper internal threaded section that is adapted to and engages with the upper threaded section, and the lower clamping body assembly has a lower internal threaded section that is adapted to and engages with the lower threaded section. The upper clamping body assembly and the lower clamping body assembly are moved closer to each other or further apart by rotating the adjusting screw.

[0009] To facilitate user operation of the adjusting screw and prevent slippage, preferably, the top of the adjusting screw is provided with an adjusting handle, and the surface of the adjusting handle is provided with anti-slip texture.

[0010] To prevent slippage between the adjusting handle and the adjusting screw, the top cross-section of the adjusting screw is further defined as an irregular circle.

[0011] Preferably, the rear part of the lower clamping assembly is connected to the support column, and the rear part of the lower clamping assembly has an upwardly extending hinge portion, and the rear part of the upper clamping assembly is hinged to the hinge portion of the lower clamping assembly.

[0012] Preferably, the embroidery frame clamp further includes a fixing screw, the head of which passes laterally through the rear of the support column and the lower clamp assembly, so that the rear of the lower clamp assembly is fixed to the front of the support column.

[0013] As a technical solution to the second technical problem mentioned above, a knob is installed at the tail of the fixing screw. The knob surface is provided with anti-slip texture. The fixing screw is fixedly connected to the embroidery frame clamp and rotatably connected to the support column. The embroidery frame clamp is rotated relative to the support column by rotating the knob.

[0014] When the embroidery frame clamp is opened, the upper clamp assembly forms an angle with the lower clamp assembly. This makes it difficult for the adjusting screw to simultaneously engage with the internal threads of both. As an improvement, the upper clamp assembly includes an upper clamp body and an upper nut fixed within it. The upper clamp body has a laterally extending mounting groove, and the upper nut is cylindrical and rotatably mounted within the mounting groove around its own axis. The axis of the upper nut extends in the same direction as the mounting groove, and the upper nut has a vertically penetrating threaded hole. The internal thread of this threaded hole is the upper internal thread segment that matches the upper thread segment of the adjusting screw. Therefore, when the aforementioned angle occurs, the upper nut can rotate itself to bring the adjusting screw channel of the upper clamp assembly and the adjusting screw channel of the lower clamp body back to the same straight line.

[0015] To further enhance the adaptive effect of this invention on the included angle, the lower clamping body assembly can also be improved in a similar way. Specifically, the lower clamping body assembly includes a lower clamping body and a lower nut fixed in the lower clamping body. The lower clamping body has a horizontally extending mounting through hole. The lower nut is cylindrical and can be rotatably mounted in the mounting through hole around its own axis. The axis of the lower nut extends in the same direction as the mounting through hole. The lower nut has a vertically penetrating threaded hole. The internal thread of the threaded hole is the lower internal thread section that matches the lower thread section of the adjusting screw.

[0016] To enable clamping of embroidery frames of different shapes, preferably, the front of the lower clamping assembly is provided with a frame fitting portion adapted to the shape of the embroidery frame. When the embroidery frame is circular, the frame fitting portion is arc-shaped to match the diameter of the embroidery frame, and the embroidery frame is located on the inner side of the frame fitting portion; when the embroidery frame is square, the frame fitting portion is straight-shaped to match the embroidery frame.

[0017] As a technical solution to the third technical problem mentioned above, preferably, the bottom of the support column has a support base, the support base has four horizontal openings facing four directions respectively, and the embroidery frame support also includes a U-shaped clip, the upper clamp of which can be inserted into any of the aforementioned horizontal openings. For example, if a user wants to switch from right-hand embroidery to left-hand embroidery, the support column needs to be rotated 180°, but the U-shaped clip also rotates 180°, causing its clamping opening to face the user instead of the table. With this technical solution, this problem can be solved simply by removing the upper clamp of the U-shaped clip from the original horizontal opening and inserting it into the horizontal opening on the opposite side.

[0018] Compared with existing technologies, this invention improves the thread structure of the adjusting screw by designing it with upper and lower thread sections in opposite directions. Therefore, when the adjusting screw is rotated in one direction, the upper thread section moves downward relative to the upper clamping assembly, while the lower thread section moves upward relative to the lower clamping assembly. The upper and lower clamping assemblies move away from each other under the action of the adjusting screw, thus achieving automatic opening without the need for manual lifting of the upper clamping assembly or reliance on elastic elements. When the adjusting screw is rotated in the opposite direction, the upper thread section moves upward relative to the upper clamping assembly, while the lower thread section moves downward relative to the lower clamping assembly. The upper and lower clamping assemblies move closer together under the action of the adjusting screw and ultimately clamp the embroidery frame. Therefore, this invention features an automatically opening clamp for the embroidery frame, allowing users to secure the embroidery frame with one hand. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Example 1

[0027] like Figures 1-5 The image shown is a preferred embodiment of an embroidery frame support according to this utility model.

[0028] The embroidery frame support consists of three parts: a vertical support post 1, a horizontal embroidery frame clip 2, and a U-shaped clip 3. (See reference) Figure 1 .

[0029] The vertically arranged support column 1 and the horizontally arranged embroidery frame clamp 2 make the embroidery frame support roughly inverted L shape. The rear part of the embroidery frame clamp 2 is connected to the upper part of the support column 1, and the front part of the embroidery frame clamp 2 can be opened and closed to hold the embroidery frame. The U-shaped clamp 3 is connected to the bottom of the support column 1, and the opening of the U-shaped clamp 3 faces to one side to hold the table or other operating platform, so as to reliably fix the support column 1 to the operating platform.

[0030] like Figure 2 As shown, the embroidery frame clamp 2 includes a pair of horizontally extending, relatively movable upper clamping components 21 and lower clamping components 22; an adjusting screw 23 vertically passing through the upper clamping components 21 and lower clamping components 22; an adjusting handle 24 located at the top of the adjusting screw 23; a fixing screw 25; and a knob 26 located at the tail of the fixing screw 25. This pair of upper clamping components 21 and lower clamping components 22 extends horizontally and remains horizontal with the operating platform fixed to the support column 1, facilitating embroidery operations. The upper clamping components 21 and lower clamping components 22 are vertically penetrated by the adjusting screw 23, which has an upper threaded section 231 and a lower threaded section 232, with the threads in the upper threaded section 231 and lower threaded section 232 having opposite helical directions. The top cross-section of the adjusting screw 23 is as shown... Figure 5The irregular circle shown has an adjusting handle 24 on its outside, and the surface of the adjusting handle 24 is provided with anti-slip texture. The upper clamping body assembly 21 has an upper internal thread section 2121 that is adapted to and engages with the upper thread section 231, and the lower clamping body assembly 22 has a lower internal thread section 2221 that is adapted to and engages with the lower thread section 232. By rotating the adjusting screw 23, the upper clamping body assembly 21 and the lower clamping body assembly 22 are moved closer or further apart, ultimately realizing the opening or clamping of the embroidery frame clamp 2.

[0031] The upper clamping assembly 21 and the lower clamping assembly 22 can move up and down relative to each other. One of the components of the upper clamping assembly 21 and the lower clamping assembly 22 is fixed relative to the support column 1. In this embodiment, the rear part of the lower clamping assembly 22 is connected to the support column 1, and a hinge portion 2213 extends upward from the rear part of the lower clamping assembly 22. The rear part of the upper clamping assembly 21 is hinged to the hinge portion 2213 of the lower clamping assembly 22, so that the upper clamping assembly 21 can rotate relative to the lower clamping assembly 22 and the support column 1 about the hinge point.

[0032] The head of the fixing screw 25 passes laterally through the rear of the support column 1 and the lower clamp assembly 22, fixing the rear of the lower clamp assembly 22 to the front of the support column 1. A knob 26 is installed at the tail of the fixing screw 25. The knob 26 has anti-slip textures. The fixing screw 25 is fixedly connected to the embroidery frame clamp 2 and rotatably connected to the support column 1. Rotating the knob 26 causes the embroidery frame clamp 2 to rotate relative to the support column 1. When the user retracts the thread, there is no need to remove the embroidery frame from the embroidery frame support, flip the embroidery frame, and then reinstall it. Simply rotating the embroidery frame clamp 2 via the knob 26 is sufficient to retract the thread.

[0033] The upper clamp assembly 21 includes an upper clamp 211 and an upper nut 212 fixed within the upper clamp 211. The upper clamp 211 has a laterally extending mounting groove. The upper nut 212 is cylindrical and can be rotatably mounted within the mounting groove 2111 around its own axis. The axis of the upper nut 212 extends in the same direction as the mounting groove 2111. The upper nut 212 has a vertically penetrating screw hole, the internal thread of which is the upper internal thread section 2121 that matches the upper thread section 231 of the adjusting screw 23. When the embroidery frame clamp 2 opens, the upper clamp assembly 21 forms an angle with the lower clamp assembly 22, which may make it difficult for the adjusting screw 23 to simultaneously engage with the internal threads of both. In this embodiment, the upper nut 212, by rotating itself, can bring the adjusting screw channel of the upper clamp assembly 21 and the adjusting screw channel of the lower clamp assembly 22 back to the same straight line, thereby avoiding the above situation. For details, please refer to [reference needed]. Figure 3 and Figure 4 .

[0034] To further improve the adaptive effect on the included angle, this embodiment also makes similar improvements to the lower clamping body assembly 22. The lower clamping body assembly 22 includes a lower clamping body 221 and a lower nut 222 fixed in the lower clamping body 221. The lower clamping body 221 has a laterally extending mounting through hole 2211. The lower nut 222 is cylindrical and can be rotatably mounted in the mounting through hole 2211 around its own axis. The axis of the lower nut 222 extends in the same direction as the mounting through hole 2211. The lower nut 222 has a vertically penetrating threaded hole. The internal thread of the threaded hole is the lower internal thread section 2221 that is adapted to the lower thread section 232 of the adjusting screw 23.

[0035] To clamp embroidery frames of different shapes, the front of the lower clamping assembly 22 is provided with a frame fitting part 2212 that adapts to the shape of the embroidery frame, such as... Figure 5 As shown. The embroidery frame in this embodiment is circular, so the frame assembly 2212 is an arc shape that matches the diameter of the embroidery frame. In use, the embroidery frame is set on the rear side of the frame assembly 2212.

[0036] In this embodiment, the bottom of the support column 1 has a support base 11, and the support base 11 has the following characteristics: Figure 1 The four horizontal openings 111 shown face four directions respectively, and the upper clamp of the U-shaped clip 3 can be inserted into any of the horizontal openings 111. For example, if a user wants to switch from right-handed embroidery to left-handed embroidery, the support 1 needs to rotate 180°, but the U-shaped clip 3 also rotates 180°, causing its clamping opening to change from facing the table to facing the user, making it impossible for the U-shaped clip 3 to clamp onto the table. With this embodiment, simply remove the upper clamp of the U-shaped clip 3 from the original horizontal opening 111 and insert it into the opposite horizontal opening 111, so that the clamping opening of the U-shaped clip 3 faces the table again.

[0037] The working principle of this embodiment is as follows:

[0038] Because the adjusting screw 23 has an upper threaded section 231 and a lower threaded section 232 with opposite rotation directions, when the embroidery frame clamp 2 is opened, the user rotates the adjusting screw 23 counterclockwise. The upper threaded section 231 moves downward relative to the upper clamping assembly 21, and the lower threaded section 232 moves upward relative to the lower clamping assembly 22. Under the action of the adjusting screw 23, the upper clamping assembly 21 and the lower clamping assembly 22 move away from each other, thus achieving automatic opening without the need to manually lift the upper clamping assembly 21 or rely on elastic elements. When the embroidery frame clamp 2 is locked, the user rotates the adjusting screw 23 clockwise. The upper threaded section 231 moves upward relative to the upper clamping assembly 21, and the lower threaded section 232 moves downward relative to the lower clamping assembly 22. Under the action of the adjusting screw 23, the upper clamping assembly 21 and the lower clamping assembly 22 move closer to each other and finally clamp the embroidery frame.

[0039] Example 2

[0040] This implementation example Figure 6 As shown, this is Embodiment 2 of the present invention. The difference between Embodiment 1 and Embodiment 2 is that the frame portion 2212 of this embodiment is straight, which is more suitable for clamping a square embroidery frame.
