Description

Technical Field

[0001] This utility model belongs to the technical field of embroidery equipment, specifically relating to embroidery frames for embroidery machines. Background Technology

[0002] Currently, many embroidery machine frames on the market use a manual fabric clamping mechanism. The fabric clamp, a sheet metal part, is used to hold the fabric against the clamping ridge. It has a clamping groove that engages with the clamping ridge. When the clamping groove opens, it engages with the clamping ridge, and the groove closes due to its own elasticity, clamping the fabric securely. However, installing the fabric clamp requires considerable force; otherwise, it is difficult to engage with the clamping ridge. Because it requires significant force, operation is inconvenient, especially since many embroidery machine operators are women, who frequently encounter problems installing and removing the fabric clamp. Another approach employs a pneumatic structure, such as patent CN210481712U, which discloses an embroidery machine including an embroidery table, an embroidery frame, a fixed frame, a pressure plate, and a cylinder. The embroidery frame is mounted on the embroidery table. The fixed frame includes a long side frame and a wide side frame. The wide side frame has several fabric clamping strips distributed along its length, each clamping a fabric clip for securing the wide edge of the fabric. The pressure plate is hinged to the long side frame, and the cylinder is mounted on the long side frame. A connecting rod is hinged to the piston rod end of the cylinder, and the other end of the connecting rod is hinged to the pressure plate. However, the pneumatic fabric clamps require multiple cylinders and corresponding cylinder drive structures, making the structure more complex and costly. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a convenient fabric clip assembly and embroidery frame for embroidery machines, which adopts a manual structure to realize the fabric clipping operation and solves the problem of the inconvenience of manual operation.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A convenient fabric clamp assembly for clamping fabric onto a fabric clamping protrusion includes a fabric clamp body, a fixing member, and a fabric clamping handle mechanism. The fabric clamp body is provided with a clamping groove that engages with the fabric clamping protrusion. The clamping groove is provided with a first clamping edge and a second clamping edge that are respectively clamped on both sides of the width of the fabric clamping protrusion.

[0006] The first clamping edge and the second clamping edge are separately arranged. The fixing member is fixed to the outside of the fabric clamp body and fixed to the first clamping edge. The fabric clamping handle mechanism includes a sliding member and a fabric clamping handle. The sliding member is connected to the second clamping edge. The fabric clamping handle mechanism has a clamping state in which the sliding member slides in a first direction, thereby driving the second clamping edge to slide and clamp the fabric, and a releasing state in which the sliding member slides in a second direction, thereby driving the second clamping edge to slide and release the fabric. The fabric clamping handle is used for rotation operation to switch the fabric clamping handle mechanism between the clamping state and the releasing state.

[0007] Preferably, the fabric clamping handle mechanism further includes a first connector and a second connector. The second end of the first connector is fixed to the fabric clamping handle, and the first end of the first connector is hinged to the sliding member, thereby causing the sliding member to slide. The first end of the second connector is hinged to the fabric clamping handle, and the second end is hinged to the fixing member. The fabric clamping handle moves the first end of the first connector by flipping up and down.

[0008] Preferably, the top of the fastener is provided with a second side extension segment extending in a second direction and beyond the second clamping edge, the second end of the second connector is hinged to the edge of the second side extension segment, and there is a gap between the edge of the second side extension segment and the second end of the first connector.

[0009] Preferably, the second side extension is a stepped structure with the second side higher than the first side, so that the edge of the second side extension is higher than the first end of the first connector.

[0010] Preferably, a fixing screw is provided between the second end of the first connector and the fabric clamping handle, the first connector is provided with an adjustment hole connected to the fixing screw, and the fabric clamping handle is provided with a threaded hole connected to the fixing screw. The relative position between the first connector and the fabric clamping handle is adjusted by the cooperation of the fixing screw and the adjustment hole to accommodate fabrics of different thicknesses.

[0011] Preferably, the top second side of the fixing member is provided with a second interval groove along the length direction, and the sliding member is provided with an oblique extension section that passes obliquely upward along the second direction through the second interval groove, and the edge of the oblique extension section is hinged to the first end of the first connecting member.

[0012] Preferably, the first end of the first connector is provided with protruding sections at intervals along the length direction, and a first interval groove is formed between adjacent protruding sections. A third interval groove is provided in the middle of the oblique extension section, and the protruding sections extend into the third interval groove and are connected to the oblique extension section by a pin.

[0013] Preferably, the top of the second clamping edge is provided with a sliding part, and the top of the fixing member is provided with a sliding groove corresponding to the sliding part. A fixing screw connects the sliding part and the sliding member to the sliding groove.

[0014] Preferably, the first clamping edge and the fixing member are an integral structure; and / or, the sliding member and the second clamping edge are an integral structure.

[0015] In addition, an embroidery frame for an embroidery machine is also provided, including the aforementioned fabric clip assembly.

[0016] This utility model adopts the above-mentioned technical solution and has the following technical effects: The fabric clamping handle mechanism includes a sliding member and a fabric clamping handle. The sliding member is connected to the second clamping edge. The fabric clamping handle mechanism has a clamping state in which the sliding member slides in a first direction, thereby driving the second clamping edge to slide and clamp the fabric, and a releasing state in which the sliding member slides in a second direction, thereby driving the second clamping edge to slide and release the fabric. The fabric clamping handle is used for rotation operation, so that the fabric clamping handle mechanism can switch between the clamping state and the releasing state. Therefore, by rotating the fabric clamping handle, the sliding member can drive the second clamping edge to slide, thereby switching the fabric clamping handle mechanism between the clamping state and the releasing state. Compared with the operation of traditional fabric clamps, the operation is more labor-saving.

[0017] In addition, since the sliding component drives the second clamping edge to slide to realize the switching of the fabric clamping handle mechanism between the clamping state and the release state, a large horizontal clamping force can be maintained in the clamping state, and a large release space can be generated when releasing, making it easy to take out the fabric.

[0018] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0029] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0030] The terminology used in this invention is for the purpose of describing specific embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "front," "rear," "X-direction," and "Y-direction," which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0033] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0034] like Figures 1 to 7 As shown, this embodiment provides a convenient fabric clamp assembly 200 for clamping fabric 12 onto a fabric clamping protrusion 11, which is located on the embroidery frame 100. As shown in the figure, after establishing a planar coordinate system, the length direction of the fabric clamp assembly 200 is the Y direction, the width direction is the X direction, and the X- direction is defined as the first direction, and the X+ direction as the second direction.

[0035] The fabric clamp assembly 200 includes a fabric clamp body 21, a fixing member 22, and a fabric clamping handle mechanism. The fabric clamp body 21 has a clamping groove 213 that engages with the fabric clamping protrusion. The clamping groove 213 has a first clamping edge 211 and a second clamping edge 212 that clamp the two sides of the width of the fabric clamping protrusion. The first clamping edge 211 and the second clamping edge 212 are separately disposed. The fixing member 22 is fixed to the outside of the fabric clamp body and to the first clamping edge 211. The fabric clamping handle mechanism includes a sliding member 26 and a fabric clamping handle 23. The sliding member 26 is connected to the second clamping edge 212. The fabric clamping handle mechanism has a clamping state where the sliding member 26 slides in a first direction, thereby driving the second clamping edge 212 to slide and clamp the fabric, and a releasing state where the sliding member slides in a second direction, thereby driving the second clamping edge 212 to slide and release the fabric. The fabric clamping handle 23 is used for rotational operation, allowing the fabric clamping handle mechanism to switch between the clamping state and the releasing state.

[0036] Therefore, rotating the fabric clamping handle causes the sliding component to move the second clamping edge, thus switching the fabric clamping handle mechanism between the clamping and releasing states. Compared to the operation of traditional fabric clamps, this method is more labor-saving.

[0037] In addition, since the sliding component drives the second clamping edge to slide to realize the switching of the fabric clamping handle mechanism between the clamping state and the release state, a large horizontal clamping force can be maintained in the clamping state, and a large release space can be generated when releasing, making it easy to take out the fabric.

[0038] Combination Figure 1 As shown and referring to existing structures, the fabric-reinforcing strip 11 includes an arc-shaped protrusion 111 and recesses 112 on both sides of the bottom. The free ends of the first clamping edge 211 and the second clamping edge 212 are provided with clamping portions 214 that engage with the recesses. The first clamping edge 211 and the second clamping edge 212 can be sheet metal parts, and the clamping portion 214 can be an arc-shaped rolled edge that is bent upward from the bottom ends of the first clamping edge 211 and the second clamping edge 212.

[0039] In some embodiments, the fabric clamping handle mechanism further includes a first connector 24 and a second connector 25. The second end of the first connector is fixed to the fabric clamping handle 23, and the first end of the first connector is hinged to the sliding member 26, thereby causing the sliding member 26 to slide. The first end of the second connector is hinged to the fabric clamping handle 23, and the second end is hinged to the fixing member 22. The fabric clamping handle 23 moves the first end of the first connector by flipping up and down.

[0040] Specifically, the fixing member 22 includes a top 221, a shoulder 222 connected to the top and extending obliquely downward on a first side, and a support leg 223 connected to the shoulder 222 and extending obliquely downward. The bottom of the support leg has an outwardly folded horizontal flange. Its second side has a second side extension 224 extending from the top in a second direction and exceeding the second flange. The second end of the second connecting member 25 is hinged to the edge of the second side extension, and there is a gap between the edge of the second side extension and the second end of the first connecting member. Furthermore, the second side extension 224 has a stepped structure with the second side higher than the first side, with a step 2241 in the middle, so that the edge of the second side extension is higher than the first end of the first connecting member. Thus, as... Figure 4 As shown, in the released state, the first connector 24, the second connector 25, and the second side extension 224 roughly form a triangular structure, thus providing a certain amount of room for movement when the fabric clamping handle 23 is flipped downwards; as Figure 7 As shown, when the fabric clamping handle 23 is flipped downwards, the first connecting member 24 moves in the first direction, and the height of the first end of the second connecting member 25 decreases. Finally, in the fabric clamping state, the fabric clamping handle 23 is completely pressed down, and the fabric clamping handle 23, the first connecting member 24, and the second connecting member 25 are in a relatively stable state. When there is no external force, the fabric clamping position of the second clamping edge 212 is maintained.

[0041] Because fabric thickness varies, a fixing screw 27 is provided between the second end of the first connecting member and the fabric clamping handle to accommodate different fabric thicknesses. The first connecting member has an adjustment hole 241 connected to the fixing screw, and the fabric clamping handle 23 has a threaded hole connected to the fixing screw. The relative position between the first connecting member and the fabric clamping handle is adjusted by the cooperation of the fixing screw and the adjustment hole to accommodate fabrics of different thicknesses. After the fixing screw is loosened, the relative position between the fabric clamping handle and the first connecting member can be adjusted. This changes the distance the sliding member and the second clamping edge move when the fabric clamping handle is operated, thus adapting to fabrics of different thicknesses. Moving in the second direction accommodates thicker fabrics, while moving in the first direction accommodates thinner fabrics. After adjustment, the fixing screw is tightened.

[0042] Specifically, the top 221 of the fixing member has a second spacer groove 225 spaced along its length on its second side. The sliding member 26 has an oblique extension section that extends obliquely upward through the second spacer groove in the second direction. The edge of the oblique extension section is hinged to the first end of the first connecting member. The oblique extension section has a rounded edge, and a third spacer groove 261 is provided in the middle of the oblique extension section. The first end of the first connecting member has protruding sections 242 spaced along its length, forming a first spacer groove 243 between adjacent protruding sections. The free end of the protruding section has a rounded edge, forming a pin sleeve. The protruding sections 242 extend into the third spacer groove 243, aligning the positions of the rounded edges on the first connecting member and the oblique extension section, and connecting them to a pin, thus achieving hinged connection between them. Because the first spacer groove 243 and the second spacer groove 225 are staggered along their length, the rounded edge of the oblique extension section extends into the second spacer groove 225. In addition, the hinge structure between the fabric clamp handle and the second connector, as well as between the second connector and the second side extension of the fixing member, is similar. It is also achieved by setting a spacer groove and an arc-shaped rolled edge along the length direction between the two opposite parts. One of the arc-shaped rolled edges extends into the spacer groove of the other, so that the positions of the arc-shaped rolled edges of the two parts correspond, thereby connecting with a pin to achieve hinge.

[0043] Specifically, the top of the second clamping edge 212 is provided with a sliding part, and the top of the fixing member 22 is provided with a sliding groove 2211 corresponding to the sliding part. A fixing screw 27 connects the sliding part and the sliding member to the sliding groove. Therefore, the sliding part and the sliding member slide together with the second fixing screw 27, and the fixing screw slides along the sliding groove 2211. In this way, when the fabric clamping handle is flipped up and down, since the sliding part, the sliding member and the second fixing screw are restricted from sliding horizontally together, the second connecting member rotates up and down, and at the same time, the first end of the first connecting member also moves horizontally.

[0044] Preferably, the first clamping edge and the fixing member are an integral structure. The sliding member and the second clamping edge are an integral structure. Of course, they can also be fixed separately.

[0045] In some embodiments, the first clamping edge 211 includes, from top to bottom, a first top edge 2111, a first inclined edge 2112, and a first vertical edge 2113. The first top edge 2111 is attached to the lower part of the top of the fixing member, and the first inclined edge 2112 is attached to the lower part of the shoulder of the fixing member. The two can be an integral structure, thereby restricting the relative movement of the first clamping edge 211. The first vertical edge is located inside the support leg of the fixing member, and the bottom of the first vertical edge 2113 has a rounded edge as a clamping part. The second clamping edge 212 includes, from top to bottom, a second top edge 2121, a second vertical edge 2122, and a second inclined edge 2123. The second top edge 2121 is attached to the lower part of the top of the fixing member, and has a sliding part on it and is connected to the fixing screw. The second inclined edge 2123 extends obliquely to the concave part on the second side, and the bottom of the second inclined edge 2123 has a rounded edge as a clamping part.

[0046] The above description is merely a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
