Description

Technical Field

[0001] This utility model relates to a wire frame structure. Background Technology

[0002] A thread holder is a device used to organize sewing threads, ensuring that the threads do not appear too messy or tangled together. Existing thread holders generally include a main rod and a horizontal thread spool mounted on the main rod, with thread inserts and thread reels on the horizontal thread spool.

[0003] In existing technology, the crossbar of the wire spool is generally horizontally mounted on the main rod, with mounting holes on the crossbar. The main rod passes through the mounting holes and is fixed to the main rod by screws and clamps. The wire post is vertically mounted on the crossbar. However, this structure limits the number of crossbars that can be mounted on the main rod. If more crossbars are needed, the height of the main rod must be increased, which can easily lead to poor stability of the wire frame and cause it to collapse during use. Furthermore, the crossbar is mounted on the main rod by a mounting bracket to facilitate installation between the crossbar and the main rod. However, the existing mounting bracket and the crossbar are integrally injection molded, resulting in difficult processing and demolding. Moreover, the connection between the mounting bracket and the main rod via screws and clamps makes disassembly and assembly cumbersome and prevents quick assembly and disassembly. Additionally, the wire post and the wire reel are screwed and fixed to the crossbar, requiring additional tools during assembly, which reduces assembly efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a wire frame structure in which the mounting base and the wire spool crossbar are set separately, and are installed and fixed after injection molding, which is convenient for processing. At the same time, the mounting base and the wire spool crossbar are easy to install and have good firmness.

[0005] The technical solution of this utility model is as follows: A wire frame structure includes a main rod and a wire spool crossbar. The wire spool crossbar is mounted on the main rod via a mounting base. Several wire posts are provided along the length of the wire spool crossbar, each wire post being detachably mounted on the crossbar and angled upwards relative to the main rod. The wire posts and the mounting base are respectively located on both sides of the wire spool crossbar. The mounting base and the wire spool crossbar are separately configured. The mounting base is detachably mounted on the main rod. A connector is provided on the side of the mounting base facing the wire spool crossbar. A corresponding insertion groove is provided on the wire spool crossbar. The connector is inserted into the insertion groove to connect the mounting base and the wire spool crossbar. The mounting base has a mounting hole and a slot communicating with the mounting hole. The main rod passes through the mounting hole. The mounting base has a locking structure that can adjust the clamping force of the mounting base on both sides of the slot, allowing the mounting base to grip or release the main rod, thereby enabling the installation or disassembly of the mounting base and the main rod.

[0006] By adopting the above technical solution, the wire column is inclined upwards, making it less likely for the wire drum to fall off when installed on the wire column. Compared with the existing method of vertically setting the wire column, this structure can install more wire columns on the main rod of the same height. The mounting base and the wire drum crossbar are set separately. During processing, they are injection molded separately and then installed when in use. Compared with the existing one-piece injection molding, it can reduce the complexity of the mold, thereby reducing the mold cost and manufacturing difficulty. Moreover, in subsequent maintenance and replacement, only the damaged parts need to be replaced instead of replacing the whole, saving costs. The advantages in production flexibility, material selection, and reduced manufacturing risks are particularly prominent when dealing with complex parts, changing functional requirements, and large-scale production. At the same time, the mounting base is connected to the main rod through a locking component, making the mounting base easy and quick to assemble and disassemble.

[0007] A further feature of this invention is that the side of the mounting base facing the horizontal bar of the spool is an inclined surface. The connector includes a first connecting plate parallel to the inclined surface and a second connecting plate located between the first connecting plate and the mounting base. The second connecting plate has first connecting blocks on both sides. The lower end of the insertion groove is open. The side of the insertion groove facing the mounting base has two opposing first elastic hooks. When the connector is inserted into the insertion groove, the first elastic hooks hook onto the first connecting blocks. There is a gap between the first elastic hooks and the side wall of the mounting groove so that the first elastic hooks can elastically deform and detach from the first connecting blocks.

[0008] The above-mentioned further design improves the firmness between the mounting base and the crossbar of the spool, and the mounting base and the crossbar of the spool can be disassembled and assembled without the need for external tools, making disassembly and assembly convenient and quick. During disassembly and assembly, the first elastic hook is driven from the bottom of the insertion slot to both sides, causing it to elastically deform and disengage from the first connecting block, so that the crossbar of the spool can be removed from the mounting base. The upper end face of the first connecting block is inclined, and the first elastic hook is also provided with an inclined surface, which facilitates elastic deformation when the first elastic hook slides downward.

[0009] A further feature of this invention is that it includes a wire clamp assembly, which includes a base plate, a guide plate, a mounting rod, and a wire clamp. The guide plate and the wire clamp are mounted on the base plate via the mounting rod, and the base plate is detachably mounted on the crossbar of the wire spool.

[0010] With the above-mentioned further design, the thread clamp can optimize the tension of the sewing thread, maintain the smooth flow of the sewing thread, and prevent the thread from tangling, making the sewing machine operate more efficiently and accurately throughout the sewing process. The base plate and the thread spool crossbar are set separately, and are connected and installed after injection molding, which facilitates processing and simplifies the mold structure.

[0011] A further improvement of this utility model is as follows: the base plate is provided with two second elastic hooks, and there is a gap between the two second elastic hooks to allow for elastic deformation. The crossbar of the spool is provided with a connecting chamber with an open upper end. The two side walls of the connecting chamber are provided with second connecting blocks, and the second elastic hooks are hooked onto the second connecting blocks to realize the installation of the base plate.

[0012] With the above-mentioned further design, the structure is simple and easy to assemble and disassemble. During installation, the second elastic hook is inserted from the opening at the top of the connecting chamber and slid downwards. When the second connecting block is in position during the sliding, the second elastic hooks move towards each other and elastically deform into the space between the two second connecting blocks. Continue sliding down until the hooking part of the second elastic hook is hooked onto the second connecting block. Assembly and disassembly are convenient and quick, without the need for other installation tools. The upper surface of the second connecting block is inclined to facilitate the sliding of the second elastic hook into the space between the two second connecting blocks.

[0013] A further feature of this invention is that the connecting chamber has a slot for exposing the second elastic hook, so as to drive the second elastic hook to elastically deform and detach from the second connecting block.

[0014] With the above-mentioned further design, it is easy for the user to insert into the slot and drive the two second elastic hooks to move towards each other, disengaging from the second connecting block, so that the bottom plate can be removed from the crossbar of the spool.

[0015] A further feature of this invention is that a tensioning post is provided on one side of the wire clamp on the base plate, and an inlet hole and an outlet hole are provided on the conductor plate.

[0016] With the above-mentioned further configuration, the sewing thread on the spool passes through the inlet hole on the guide plate, then around the clamp of the thread clamp, then around the tensioning post, and finally passes through the outlet hole. The tensioning post prevents the sewing thread from falling off the thread clamp and keeps the sewing thread taut, making sewing smoother.

[0017] A further improvement of this invention: the locking structure includes a locking member and a limiting rod. One end of the limiting rod passes through the locking member and through the slot, and a limiting member is provided on the limiting rod. The other end of the limiting rod is provided with a limiting part. An axial limiting space is formed between the limiting member and the limiting part. The locking member is rotatably mounted on the limiting rod and is located between the limiting part and the mounting base. The limiting part abuts against the outer surface of the locking member. One side of the inner surface of the locking member and the outer surface of the mounting base is provided with an inclined surface or an arc-shaped surface, and the other side is provided with a pressing surface. When the locking member rotates, the pressing surface cooperates with the inclined surface or the arc-shaped surface to adjust the clamping force of the mounting bases on both sides of the slot to realize the installation or removal of the spool crossbar.

[0018] With the above further setting, the size of the slot opening can be adjusted by rotating the locking member, so as to adjust the clamping force of the mounting seat. The disassembly and assembly of the bobbin cross bar can be realized without tools, which is convenient, fast, time-saving and labor-saving. The adjustment is convenient and fast. When the locking member rotates, the pressing surface cooperates with the inclined surface or the arc surface, and one side wall of the mounting seat axially slides relative to the other side wall along the axial direction of the limiting rod, so that the slot becomes larger or smaller. When unlocking, it can axially slide relative to the main rod to realize disassembly. When locking, it cannot move, and the stability is good.

[0019] A further setting of the present utility model: A plurality of installation channels are provided on the bobbin cross bar along its length direction. At least two third elastic hooks are provided at the lower end of the thread post. A gap is provided between adjacent third elastic hooks for elastic deformation. Each third elastic hook passes through the installation channel and hooks on the bottom of the bobbin cross bar to realize the connection between the thread post and the bobbin cross bar. An activity space is provided in the installation channel for each third elastic hook to elastically deform inward so that the elastic hook disengages from the bobbin cross bar.

[0020] With the above further setting, there is a gap between adjacent third elastic hooks. When the third elastic hook is located in the installation channel, each third elastic hook deforms inward so that the third elastic hook can pass through the installation channel. After passing through the installation channel, the third elastic hook will rebound due to its own elasticity, and the third elastic hook hooks the bottom of the bobbin cross bar to complete the clamping connection between the thread post and the bobbin cross bar. When disassembling, press each third elastic hook inward to make it disengage from the bottom of the bobbin cross bar, and then pull out the thread post outward to remove the thread post from the bobbin cross bar, making the disassembly and assembly of the thread post very convenient and not damaging the thread post after disassembly.

[0021] A further setting of the present utility model: It further includes a thread passing bracket. The thread passing bracket is arranged in a U shape or an H shape. Both ends of the thread passing bracket are connected to the bobbin cross bar. Thread passing holes are provided on the cross bar in the middle of the thread passing bracket corresponding to the positions of each thread post.

[0022] With the above further setting, the sewing thread on the bobbin passes through the thread clamping component and then through the thread passing hole, playing a guiding role to ensure that the thread will not get stuck or knotted during sewing and can maintain smooth flow.

[0029] like Figure 1-15As shown, a thread frame structure includes a main rod 1 and a thread spool crossbar 2. The thread spool crossbar 2 is mounted on the main rod 1 via a mounting base 3. Several thread posts 6 are provided along the length of the thread spool crossbar 2, each thread post 6 being detachably mounted on the thread spool crossbar 2 and angled upwards relative to the main rod 1. The thread posts 6 and the mounting base 3 are respectively located on opposite sides of the thread spool crossbar 2. A support base 11 is provided at the bottom of the main rod 1, through which the thread frame is mounted on a sewing machine. The mounting base 3 and the thread spool crossbar 2 are separate components. The mounting base 3 is detachably mounted on the main rod 1. A connector 31 is provided on the side of the mounting base 3 facing the thread spool crossbar 2. The horizontal bar 2 of the spool is provided with a corresponding insertion groove 21. The connector 31 is inserted into the insertion groove 21 to connect the mounting base 3 and the horizontal bar 2 of the spool. The horizontal bar 2 of the spool can be inclined relative to the main rod 1 as a whole, or only the surface of the mounting post 6 can be inclined relative to the main rod 1. The mounting base 3 is provided with a mounting hole 32 and a slot 33 communicating with the mounting hole 32. The main rod 1 passes through the mounting hole 32. The mounting base 3 is provided with a locking structure 5. The locking structure 5 can adjust the clamping force of the mounting base 3 on both sides of the slot so that the mounting base 3 clamps or loosens the main rod 1, thereby realizing the installation or disassembly between the mounting base 3 and the main rod 1. The post is inclined upward. This design prevents the wire spool from falling off the wire post when installed. Compared to the existing vertically installed wire posts, this structure allows for the installation of more wire posts on the same height main pole. Compared to the existing horizontally installed wire spool crossbars, when the crossbars are inclined relative to the main pole, more crossbars can be installed on the main pole at the same height. Wire spool crossbars can also be installed on both sides of the main pole. The crossbars on both sides can share a common mounting base or use separate mounting bases. When wire spool crossbars are installed on both sides, no wire clamp assembly is installed on the crossbars. The mounting base 3 and the crossbar 2 are separate units, injection molded separately during manufacturing and then installed during use. Compared to existing one-piece injection molding, this mounting method reduces the complexity of the mold, thereby lowering the mold cost and manufacturing difficulty. Moreover, in subsequent maintenance and replacement, only the damaged parts need to be replaced, without replacing the entire unit, saving costs. It has advantages in production flexibility, material selection, and reduced manufacturing risks, especially when dealing with complex parts, changing functional requirements, and large-scale production. At the same time, the mounting base is connected to the main rod through a locking component, making the mounting base easy and quick to assemble and disassemble. To ensure the stability of the spool crossbar 2, two main rods 1 can be set, and two mounting bases 3 are provided accordingly, each sleeved on the corresponding main rod 1.

[0030] The specific structure of the spool crossbar 2 being inclined relative to the main rod 1 includes a sloping side of the mounting base 3 facing the spool crossbar 2. The connector 31 includes a first connecting plate parallel to the sloping side and a second connecting plate located between the first connecting plate and the mounting base. First connecting blocks 311 are provided on both sides of the second connecting plate. The insertion groove 21 has an opening at its lower end, and two opposing first elastic hooks 211 are provided on the side of the insertion groove facing the mounting base 3. When the connector 31 is inserted into the insertion groove, the first elastic hooks 211 hook onto the first connecting blocks 311. A gap is provided between the side walls of the groove 35 so that the first elastic hook 211 can elastically deform and disengage from the first connecting block 311, thereby improving the firmness between the mounting base 3 and the spool crossbar 2. Furthermore, the mounting base 3 and the spool crossbar 2 can be disassembled and assembled without the need for external tools, making disassembly and assembly convenient and quick. During disassembly and assembly, the first elastic hook 211 is driven from the bottom of the insertion groove to both sides, causing it to elastically deform and disengage from the first connecting block 311, so that the spool crossbar can be removed from the mounting base 3. The upper end face of the first connecting block 311 is inclined, and the first elastic hook 211 is also provided with an inclined surface, which facilitates elastic deformation when the first elastic hook 211 slides downward.

[0031] It also includes a thread clamp assembly 4, which comprises a base plate 41, a guide plate 42, a mounting rod 43, and a thread clamp 44. The guide plate 42 and the thread clamp 44 are mounted on the base plate 41 via the mounting rod 43. The base plate 41 is detachably mounted on the thread spool crossbar 2. The thread clamp 44 optimizes the tension of the sewing thread, maintains the smooth flow of the sewing thread, and prevents the thread from tangling, making the sewing machine operate more efficiently and accurately throughout the sewing process. The base plate 41 and the thread spool crossbar 2 are separately designed and connected after injection molding, which facilitates processing and simplifies the mold structure. The thread clamp 44 is existing technology and therefore is not further described. Detailed explanation: A tensioning post 45 is provided on one side of the thread clamp 44 on the base plate 41. The guide plate 42 has an inlet hole and an outlet hole. The number of thread clamps, guide plates, and mounting rods is the same as the number of thread posts on each spool crossbar, corresponding to each thread post. The sewing thread on the spool passes through the inlet hole on the guide plate, then around the clamp of the thread clamp, then around the tensioning post, and finally through the outlet hole. The tensioning post prevents the sewing thread from falling off the thread clamp and keeps the sewing thread taut, making sewing smoother. Specifically, the installation structure between the base plate 41 and the spool crossbar 2 is as follows: the base plate 41 has two second springs... The device includes a second elastic hook 411 with a gap between it to allow for elastic deformation. The crossbar 2 of the spool has a connecting chamber 22 with an open upper end. Second connecting blocks 221 are located on opposite side walls of the connecting chamber 22. The second elastic hooks 411 are hooked onto the second connecting blocks 221 to install the base plate 41. The structure is simple and easy to assemble and disassemble. During installation, the second elastic hooks 411 are inserted from the open upper end of the connecting chamber 22 and slid downwards. When the second connecting blocks 221 are in position during sliding, the second elastic hooks 411 move towards each other, elastically deforming and entering between the two second connecting blocks 221. Continue sliding down until the hooking part of the second elastic hook 411 hooks onto the second connecting block 221. It is convenient and quick to disassemble and assemble without the need for other installation tools. The upper end face of the second connecting block 221 is inclined to facilitate the second elastic hook 411 to slide into the two second connecting blocks 221. The connecting chamber 22 has a slot 222 for the second elastic hook 411 to be exposed, so as to drive the second elastic hook 411 to elastically deform and detach from the second connecting block 221. It is convenient for the user to insert into the slot 222 and drive the two second elastic hooks 411 to move towards each other and detach from the second connecting block 221, so that the bottom plate 41 can be removed from the wire spool crossbar 2.

[0032] In embodiment 1 of the locking structure 5, the locking structure 5 includes a locking member 51 and a limiting rod 52. One end of the limiting rod 52 passes through the locking member 51 and through the slot 33, and the limiting rod 52 is provided with a limiting member 521. The other end of the limiting rod 52 is provided with a limiting part 522. An axial limiting space is formed between the limiting member 521 and the limiting part 522. The locking member 51 is rotatably mounted on the limiting rod 52 and is located between the limiting part 522 and the mounting base 3. The limiting part 522 abuts against the outer surface of the locking member 51. One side of the inner surface of the locking member 51 and the outer surface of the mounting base 3 is provided with an inclined surface 34 or an arc-shaped surface, and the other side is provided with a pressing surface 511, so as to lock the locking member 51. When 51 rotates, the pressing surface 511 engages with the inclined surface 34 or the arc-shaped surface, adjusting the clamping force of the mounting seats 3 on both sides of the slot 33 to install or remove the spool crossbar 2. The opening size of the slot 33 can be adjusted by rotating the locking component 51, thereby adjusting the clamping force of the mounting seats 3. The spool crossbar 2 can be installed and removed without tools, making it convenient, quick, and labor-saving. When the locking component 51 rotates, the pressing surface 511 engages with the inclined surface 34 or the arc-shaped surface, causing one side wall of the mounting seat 3 to slide axially relative to the other side wall on the limiting rod 52, thus making the slot 33 larger or smaller. When unlocked, it can slide axially relative to the main rod 1 to achieve disassembly; when locked, it cannot move, providing good stability and resistance. The pressure surface 511 can be a protrusion on one side, or it can be an inclined surface 34 or an arc surface; the spool crossbar 2 can be disassembled and assembled without the need for tools, which is convenient, quick, time-saving, and labor-saving. The adjustment is convenient and quick. Compared with locking or unlocking the spool crossbar 2 by means of bolts and nuts, which requires turning the nut many times, the locking structure 5 of this application is more convenient and quick to operate. Only a small rotation angle is needed to unlock or lock. For example, when the locking part 51 is rotated clockwise, the locking part 51 moves on the inclined surface 34 or the arc surface, so that one side wall of the mounting seat 3 is squeezed and axially slid relative to the other side wall in the axial space, thereby making the slot 33 smaller, and the mounting seat 3 holds It is tightly locked, cannot move, and has good stability. When rotated in the opposite direction, the slot 33 enlarges to unlock, allowing it to slide axially relative to the main rod 1 for disassembly. Of course, it can also unlock when rotated clockwise and lock when rotated counterclockwise. Depending on the specific inclined surface setting, the locking member 51 can also be provided with a lug 512 to facilitate the rotation of the locking member 51. Specifically, the cooperation between the limiting rod 52 and the locking member 51 is as follows: the locking member 51 is provided with a receiving groove 513, and the bottom of the receiving groove 513 is provided with a through hole 514 for the limiting rod 52 to pass through. The limiting part 522 of the limiting rod 52 is located in the receiving groove 513 and abuts against the bottom wall of the receiving groove 513, so that the limiting part 522 is not exposed, which is more aesthetically pleasing and safer.

[0033] Specifically, the limiting member 521 is set with a nut, and the limiting rod 52 can be set with a bolt. The nut and the locking member 51 are respectively located at both ends of the limiting rod 52. In this embodiment, the corresponding mounting base 3 can also be provided with a mounting groove 35 and a movable groove 36 on both sides of the slot 33. The mounting groove 35 and the movable groove 36 are both connected to the slot 33. The nut is set in the mounting groove 35, and the locking member 51 is rotatably set in the movable groove 36. One end of the limiting rod 52 extends through the slot 33 into the mounting groove 35 and is threadedly connected to the nut. The bottom wall of the movable groove 36 is provided with an inclined surface 34, an arc surface, or a pressing surface 511.

[0034] Alternatively, the limiting member 521 and the limiting part 522 can be riveted to both ends of the limiting rod 52.

[0035] Alternatively, the limiting component 521 can be set with a limiting pin, and the limiting rod 52 has an insertion hole, with the limiting pin passing through the insertion hole.

[0036] In embodiment 2 of the locking structure 5, the locking structure 5 includes a locking member 51 and a limiting rod 52. The limiting rod 52 is bolted on, with one end passing through the locking member 51 and threaded through the slot 33 to the mounting base 3, and the other end having a limiting part 522. The locking member 51 is rotatably mounted on the limiting rod 52 and located between the limiting part 522 and the mounting base 3. The limiting part 522 abuts against the outer surface of the locking member 51. One side of the inner surface of the locking member 51 and the outer surface of the mounting base 3 has an inclined surface 34 or an arc surface, and the other side has a pressing surface 5. 11. When the locking member 51 rotates, the pressing surface 511 cooperates with the inclined surface 34 or the arc surface to adjust the clamping force of the mounting seats 3 on both sides of the slot 33; in this embodiment, threaded holes and movable grooves 36 can also be provided on the corresponding mounting seats 3 on both sides of the slot 33. The threaded holes and movable grooves 36 are connected to the slot 33. The locking member 51 is rotatably located in the movable groove 36. One end of the limiting rod 52 passes through the locking member 51 and extends through the slot 33 to the threaded hole and is threadedly connected to the threaded hole. An inclined surface 34 or an arc surface or a pressing surface 511 is provided on the bottom wall of the movable groove 36.

[0037] The horizontal bar 2 of the spool is provided with several installation channels 23 along its length. The lower end of the spool post 6 is provided with at least two third elastic hooks 61. There is a gap between two adjacent third elastic hooks 61 to allow for elastic deformation. Each third elastic hook 61 passes through the installation channel 23 and hooks onto the bottom of the horizontal bar 2 to connect the spool post 6 and the horizontal bar 2. The installation channel 23 is provided to allow each third elastic hook 61 to elastically deform inward so that the elastic hooks can disengage from the moving space of the horizontal bar 2. There is a gap between adjacent third elastic hooks 61. When the third elastic hook 61 is located in the installation channel 23, each third elastic hook 61 deforms inward so that the third elastic hook 61 can pass through the installation channel 23. After passing through the installation channel 23, the third elastic hook 61 will be elastically deformed by its own elasticity. The elastic hook 61 rebounds upon contact with the bottom of the spool crossbar 2, thus securing the wire post 6 to the spool crossbar 2. For disassembly, press the third elastic hook inwards to disengage it from the bottom of the spool crossbar 2, then pull the wire post 6 outwards to remove it from the spool crossbar 2. This makes the installation and removal of the wire post 6 very convenient and prevents damage after disassembly. A positioning boss 62 is located above each of the third elastic hooks 61 on the wire post 6, and a positioning step 231 is provided within the installation channel 23. When the wire post 6 is installed within the installation channel 23, the positioning boss 62 abuts against the positioning step 231, axially positioning the wire post 6 and preventing it from detaching from the spool crossbar 2. A sleeve 63 is also fitted onto the wire post 6, allowing the spool to be fitted over the sleeve 63 for positioning and preventing slippage.

[0038] It also includes a thread guide 7, which is arranged in the shape of a U or H. Both ends of the thread guide 7 are connected to the crossbar 2 of the thread spool. The crossbar in the middle of the thread guide 7 is provided with thread holes 71 corresponding to the positions of each thread post 6. The sewing thread on the thread spool passes through the thread clamp assembly and then through the thread holes 71, which plays a guiding role and ensures that the thread will not get stuck or knotted during the sewing process, and can maintain smooth flow.
