Handmade carpet tools not only meet people's needs for designing and making carpets themselves, but also provide a fun and engaging experience, enhancing the enjoyment of daily life.

[0003] The support frame used to stretch the carpet backing is an important component of handmade carpet tools. It is used to properly stretch the carpet backing before the flocking machine can be used for flocking. Existing backing frames typically consist of a frame with fabric threading pins. In use, the backing is manually stretched and the fabric threading pins are used to secure the edges, achieving the desired stretching effect. However, this type of backing frame has the following problems: it cannot be disassembled, takes up considerable space when not in use, and is inconvenient for storage and transport.

[0004] In summary, it is necessary to develop and design a support structure for the base fabric to solve the aforementioned technical problems. Summary of the Invention

[0017] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0018] Please see Figure 1 This utility model discloses a backing fabric support for carpet flocking, comprising a rectangular support frame with supporting back frames on both sides of the back of the support frame. The support frame is used to fix the carpet backing fabric and stretch it to a suitable tension to facilitate subsequent manual flocking operations. The supporting back frames support the support frame. Typically, this backing fabric support is used on a table, with the lower end of the supporting back frames fixed to the table, the support frame in a vertical or slightly tilted position, and the bottom of the support frame resting on the table.

[0019] The horizontal border (including the top and bottom borders) and vertical border (including the left and right borders) of the fabric support frame each include multiple frame segments 2 of equal length. In the structure shown in the figure, each border of the fabric support frame includes two frame segments 2.

[0020] Horizontally adjacent frame segments 2 (referring to the frame segments 2 of the top and bottom edges) are connected by straight connectors 4, and vertically adjacent frame segments 2 (referring to the frame segments 2 of the left and right edges) are connected by straight connectors 4. Adjacent horizontal frame segments 2 and vertical frame segments 2 (referring to the frame segments 2 of the upper left, upper right, lower left, and lower right corners) are connected by L-shaped connectors 1 or T-shaped connectors 11.

[0021] like Figure 1 As shown in the figure, in this embodiment, the lower left and lower right corners are connected by T-shaped connectors 11. The advantage of this is that the T-shaped connector 11 has a connecting end on the outside. Therefore, when the T-shaped connector 11 is used at the bottom of the fabric support frame, the width of the bottom of the fabric support frame can be expanded to a certain extent, which can improve the stability of the fabric support frame.

[0022] In this embodiment, frame segment 2 is a square steel pipe, and L-shaped connector 1, straight connector 4, and T-shaped connector 11 are injection molded parts. The L-shaped connector 1 has slots 5 at its two insertion portions, the straight connector 4 has slots 4 at its two insertion portions, and the T-shaped connector 11 has slots 5 at its longitudinal insertion portion and one of its transverse insertion portions. Figure 1 As shown, the L-shaped connector 1 is plugged into the end of the frame segment 2 and can be fixed to the frame segment 2 with assembly screws 3 to prevent arbitrary separation; the straight connector 4 is plugged into the end of the frame segment 2 and can be fixed to the frame segment 2 with assembly screws 3 to prevent arbitrary separation; the T-shaped connector 11 is plugged into the end of the frame segment 2 and can be fixed to the frame segment 2 with assembly screws 3 to prevent arbitrary separation.

[0023] The purpose of providing the slot 5 at the insertion part of each connector is to facilitate the insertion of the insertion part into the steel pipe port of the frame segment 2. During connection, the insertion part can be squeezed by pressing. Due to the presence of the slot 5, the insertion part can be appropriately contracted, which makes it easier to insert into the steel pipe port of the frame segment 2.

[0024] Each frame segment 2 is provided with forward-extending fabric-threading needles 10, so that the front of the supporting frame has a ring of fabric-threading needles 10, that is, the front of the top frame, bottom frame, left frame and right frame each have a row of fabric-threading needles 10. When fixing the carpet backing, the carpet backing is stretched taut and moved toward the supporting frame until the edges of the carpet backing contact the frames of the supporting frame. At this time, each row of fabric-threading needles 10 pierces the carpet backing. Then the carpet backing is released, and the carpet backing is fixed and stretched on the supporting frame.

[0025] In this embodiment, an adjustable crossbeam 9 with adjustable height is also provided inside the support frame. A row of fabric-threading needles 10 extending forward is provided on the adjustable crossbeam 9. The function of setting the adjustable crossbeam 9 with adjustable height is: when the carpet backing fabric used is relatively narrow (when the longitudinal width of the backing fabric is less than the height of the support frame), it is impossible to fix the upper and lower edges of the backing fabric at the same time, and therefore it is impossible to tighten the backing fabric. At this time, the adjustable crossbeam 9 can be installed and set to a suitable height. Then, the lower edge of the backing fabric can be fixed by the adjustable crossbeam 9 and its fabric-threading needles 10, thereby tightening the backing fabric.

[0026] Please see Figure 2 It can be seen that: Fixing plates 8 are provided at both the front and rear ends of the adjustable crossbeam 9. The two fixing plates 8 are located at the front and rear of the frame segment 2 on this side, respectively, and the front fixing plate 8 is located between two longitudinally adjacent fabric threading needles 10 on the frame segment 2. At this time, the two fabric threading needles 10 located above and below the front fixing plate 8 provide a positioning function for this fixing plate 8. Due to the limiting effect of these two fabric threading needles 10, the adjustable crossbeam 9 will not move up or down during use after being set in position.

[0027] In this embodiment, the adjustable crossbeam 9 is a square steel pipe. The inner ends of the two fixing plates 8 are fixedly connected to the ends of the adjustable crossbeam 9 by fixing bolts 7, and the outer ends of the two fixing plates 8 are connected by fixing bolts 7. In order to improve the convenience of operation, the aforementioned fixing bolts 7 are selected as rat ear bolts.

[0028] The structure of the fabric threading needle 10: The fabric threading needle 10 is selected as a steel nail. When installing rows of fabric threading needles 10 on the steel pipes of both the frame segment 2 and the adjustable crossbeam 9, the steel nails are driven through the steel pipes from back to front. The fabric threading needles 10 should have a suitable and equal exposed length at the front of both the frame segment 2 and the adjustable crossbeam 9, and the spacing between adjacent fabric threading needles 10 should be equal.

[0029] Please see Figure 3 It can be seen that: The support frame includes a diagonal brace 15, the upper end of which is connected to the support frame via a frame adapter 6, and a root fixing member 16 is installed at the lower end of the diagonal brace 15. The frame adapter 6 is detachably connected to the support frame, and the root fixing member 16 is used for fixed connection to the desktop.

[0030] In this embodiment, the diagonal brace 15 is a square steel pipe, the frame adapter 6 and the root fixing part 16 are injection molded parts, the frame adapter 6 is fixedly connected to the longitudinally placed frame segment 2 on the support frame, the upper end of the diagonal brace 15 is hinged to the frame adapter 6, and the lower end of the diagonal brace 15 is hinged to the root fixing part 16.

[0031] Specifically, the frame adapter 6 has a groove at the front and a groove at the rear. During assembly, the upper end of the diagonal brace 15 is inserted into the groove at the rear of the frame adapter 6 and connected by a bolt. The upper frame segment 2 of the left or right side frame of the fabric support frame is inserted into the groove at the front of the frame adapter 6 and fixed by a bolt. The root fixing member 16 includes a base plate and two ear plates oppositely arranged on the base plate. The lower end of the diagonal brace 15 is located between the two ear plates of the root fixing member 16 and connected by a bolt. During carpet flocking, the root fixing member 16 is fixedly connected to the tabletop. For example, the base plate of the root fixing member 16 can be glued to the tabletop, or a connecting hole can be provided on the base plate and bolts can be used to fix the base plate of the root fixing member 16 to the tabletop.

[0032] To guide the carpet yarn during the flocking process and prevent tangling, a yarn holder 13 with multiple yarn loops 14 at its bottom is included. The base of the yarn holder 13 is detachably connected to the top side of the fabric support frame. In use, the carpet yarn released from the spool is passed through the yarn loops 14 and connected to a handheld electric / manual flocking machine for flocking. Because the yarn is guided by the yarn loops 14, tangling is avoided.

[0033] In this embodiment, the horizontal frame segment 2 located at the upper left corner of the support frame is connected to the vertical frame segment 2 by a T-shaped connector 11, and the root of the hanging frame 13 is detachably connected to the T-shaped connector 11 through the hanging frame adapter 12.

[0034] Please see Figure 4 As can be seen, the cable hanger 13 is a square steel pipe, and the cable hanger adapter 12 is an injection-molded part. The cable hanger adapter 12 includes a sleeve and a plug. The plug of the cable hanger adapter 12 is inserted into the base of the cable hanger 13, and the sleeve of the cable hanger adapter 12 is inserted into the exposed end of the T-shaped connector 11 in the upper left corner. As shown in the figure, the cable hanger adapter 12 has a certain angle between the sleeve and the plug, so that after the cable hanger 13 is installed on the support frame, it tilts forward, that is, towards the operator.

[0035] How to use: Assemble the support frame and place the two support back frames on the table. Fix the two root fixing pieces 16 to the table and let the bottom edge of the front support frame rest on the table. Adjust the posture of the support frame appropriately so that it is in a vertical or slightly tilted position. Install the hanging bracket 13.

[0036] Depending on the width of the carpet backing used, selectively install the adjustable crossbeam 9; then stretch the backing and move it toward the support frame until the bottom edges contact the frame edges, and each row of needles 10 pierces the backing. After the backing is released, it is fixed and stretched on the support frame. Then, an electric / manual flocking machine can be used to perform flocking on the backing.

[0037] When not in use, the support fabric device can be disassembled and stored. Specifically: disconnect the frame adapter 6 from the support fabric frame to complete the separation of the support fabric frame from the support back frame; disconnect the wire frame adapter 12 from the support fabric frame; remove the adjustable crossbeam 9 from the support fabric frame; and then disassemble the support fabric frame into multiple frame segments 2 and multiple connectors. The disassembled parts can be stored in a box, which takes up little space and is easy to carry and use.
