Description

Technical Field

[0001] The present application relates to the field of textile auxiliary tools, and in particular to a U-shaped clip shears storage device for a sewing machine. Background Art

[0002] Currently, in the garment processing industry, U-shaped clip shears are a commonly used tool for cutting various types of fabrics. These U-shaped clip shears are often placed haphazardly due to their high frequency of use and complex operating environments, affecting the operator's work efficiency.

[0003] The industry has adopted a number of solutions to this problem, with two main approaches being used: using dedicated tool boxes to store various tools, and using wall-mounted or table-top hooks to hang tools. Each approach has its own advantages and disadvantages. While tool boxes can effectively protect tools and prevent them from being lost, they are bulky and take up a lot of space. Therefore, they are typically placed in a designated location, requiring operators to reach for them each time they use them, which is very inconvenient. Furthermore, opening the tool box to locate a specific tool is time-consuming. Wall-mounted or table-top hooks are relatively lightweight and save space, but they can easily cause tools to fall, especially for sharp tools like U-shaped clips, which can pose a safety hazard. Utility Model Content

[0004] In order to fix the position of the U-shaped clip scissors, reduce the situation where the U-shaped clip scissors are lost due to being placed randomly or affect the operator's use, and ensure the operator's work efficiency, the present application provides a U-shaped clip scissors storage device for a sewing machine.

[0005] The present application provides a U-shaped clip scissors storage device for a sewing machine, which adopts the following technical solution:

[0006] A U-shaped clip scissors storage device for a sewing machine comprises a telescopic connector mounted on a sewing machine table. The telescopic connector has a telescopic function, and one end of the telescopic connector away from the sewing machine table is used for connecting with the U-shaped clip scissors.

[0007] By adopting the above technical solution, the U-shaped clamp shears are used to trim the burrs and defects of the trimmed cloth. By adjusting the telescopic connecting part, the U-shaped clamp shears can adapt to the cloth working conditions of different sewing machine tables, making the operation of stretching and retracting the U-shaped clamp shears more convenient.

[0008] Optionally, the telescopic connecting member is a spring.

[0009] By adopting the above technical solution, the spring is used to suspend and store the U-shaped clip shears, thereby avoiding the loss of the U-shaped clip shears during use, and at the same time making it easier for the operator to pick up the U-shaped clip shears and perform operations on the scraps that cannot be trimmed.

[0010] Optionally, a fixed shell detachably connected to the sewing machine table is provided, one end of the telescopic connector is installed in the fixed shell, and the other end of the telescopic connector passes through the fixed shell for connection with the U-shaped clip.

[0011] By adopting the above technical solution, the fixed shell accommodates the function of the telescopic connector. At the same time, the other end of the telescopic connector passes through the fixed shell for connection with the U-shaped clamp shears, thereby performing a fixed-point retraction operation on the U-shaped clamp shears.

[0012] Optionally, a fixed shaft is fixed in the fixed shell, and the telescopic connecting part includes a coil spring fixed on the fixed shaft, a drum fixed on the outer ring of the coil spring, and a telescopic strip with one end fixed on the drum, and the end of the telescopic strip away from the drum passes through the fixed shell for connection with the U-shaped clamp.

[0013] By adopting the above technical solution, the coil spring is used to connect to the fixed shaft, and the outer side of the coil spring is connected to the driving reel for rotation, so that the telescopic strip is wound or loosened, thereby driving the U-shaped clip shears located outside to perform a recovery operation.

[0014] Optionally, a one-way ratchet assembly is provided between the fixed shaft and the reel for limiting the reel to rotate in one direction only.

[0015] By adopting the above technical solution, the one-way ratchet assembly can limit and fix the reel after rotation, avoiding the use of the rear coil spring to drive the reel to rotate in the opposite direction.

[0016] Optionally, the one-way ratchet assembly includes an inner gear ring fixed on the inner ring of the reel, a one-way tooth hinged on the outer wall of the fixed shaft, and a spring. The spring is located on the inner tooth side of the one-way tooth, one end of the spring is connected to the one-way tooth, and the other end of the spring is connected to the outer wall of the fixed shaft. A rod group is provided on the fixed shaft to control the engagement or separation of the one-way tooth and the inner gear ring.

[0017] By adopting the above technical solution, the inner gear ring is hinged to the spring connected to the outer wall of the fixed shaft. The spring controls the tooth top of the one-way tooth to be in meshing relationship with the one-way tooth under normal conditions. After the rod group is pressed down, the one-way tooth is controlled to release the meshing relationship with the inner gear ring.

[0018] Optionally, the rod group includes an elastic part fixed to the top of the fixed shaft, a pressing head fixed to the end of the elastic part away from the fixed shaft, and a shift rod fixed to one side of the pressing head. The side of the shift rod away from the pressing head extends to the side wall of the fixed shaft and fits with the outer wall of the fixed shaft. A protrusion is fixed to one side of the shift rod. The side of the protrusion away from the shift rod is an inclined surface, and the inclined surface of the protrusion faces the one-way tooth. When the pressing head is operated to squeeze the elastic part, the inclined surface of the protrusion drives the one-way tooth to rotate and squeezes the spring to release the meshing relationship between the one-way tooth and the inner gear ring.

[0019] By adopting the above technical solution, in the working state, the U-shaped clamp shears stretches the telescopic strip, and after reaching the trimming position, the one-way teeth engage with the inner gear ring, thereby limiting the reverse rotation of the reel; after completing the trimming work, the operator presses down the control lever and the elastic part cooperating with it contracts, the control lever drives the one-way teeth to separate from the inner gear ring, and the reverse rotation of the coil spring drives the telescopic strip to be recovered and wound, and then a new round of stretching and trimming process begins.

[0020] Optionally, an output port for the telescopic strip to pass through is opened on the outer wall of the fixed shell, and a damping group for damping the telescopic strip is arranged in the output port; the damping group includes a mounting sleeve installed in the output port, an elastic sleeve fixed on the inner wall of the mounting sleeve, and a damping sleeve located on the inner wall of the elastic sleeve, the middle part of the damping sleeve is for the telescopic strip to pass through, and the width of the penetration port of the damping sleeve is smaller than the telescopic strip to damp and clamp the telescopic strip.

[0021] By adopting the above technical solution, the mounting sleeve is used to fix the damping group on the output port opened on the fixed shell, and the elastic sleeve provides elastic deformation for the damping sleeve, so that the width of its penetration port is smaller than the telescopic strip, thereby playing an effective sealing and damping role.

[0022] Optionally, a plurality of telescopic connectors are provided, and the plurality of telescopic connectors are spaced apart along the length direction of the fixed axis, and one end of each telescopic connector away from the fixed axis is used to be connected to a U-shaped clip.

[0024] Optionally, a snap-on U-ring is fixed to the sewing machine table.

[0026] Optionally, one side of the fixed shell is open, and the open side of the fixed shell is connected to a ruler cover.

[0027] By adopting the above technical solution, the ruler cover is used to seal the telescopic connector placed in the fixed housing.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] The spring is used to suspend and store the U-shaped clip shears to avoid the loss of the U-shaped clip shears during use, and at the same time it is convenient for the operator to pick up the U-shaped clip shears and perform operations on the scraps that cannot be trimmed.

[0030] The fixed shell accommodates the telescopic connecting piece. At the same time, the other end of the telescopic connecting piece passes through the fixed shell to be connected to the U-shaped clamp shears, thereby performing a fixed-point retraction operation on the U-shaped clamp shears.

[0044] The following is combined with Figure 1-11 This application is described in further detail.

[0045] The embodiment of the present application discloses a U-shaped clip scissors storage device for a sewing machine.

[0046] Example 1

[0047] Reference Figure 1 The U-shaped clip scissors storage device for a sewing machine includes a telescopic connector 2 mounted on a sewing machine table. The telescopic connector 2 has a telescopic function. The specific telescopic connector 2 can be a spring, a rubber band, or the like.

[0048] The implementation principle of the first embodiment is as follows: when in use, the U-shaped clip scissors 1 is directly installed on the end of the telescopic connector 2 away from the sewing machine table, and the operator holds the U-shaped clip scissors 1 to cut the fabric to be trimmed; due to the telescopic function of the telescopic connector 2, the operator can drive the U-shaped clip scissors 1 to any place to operate, and after use, the telescopic connector 2 can also fix the position of the U-shaped clip scissors 1 on the sewing machine table to avoid loss.

[0049] Example 2

[0050] Reference Figure 2 and Figure 3 The difference between this embodiment and the first embodiment lies in the difference in the telescopic connecting member 2. In this embodiment, a fixed shell 3 is detachably connected to the sewing machine table, and a fixed shaft 5 is vertically provided in the fixed shell 3. One end of the telescopic connecting member 2 is installed on the fixed shaft 5, and the other end of the telescopic connecting member 2 extends out of the fixed shell 3 and is connected to the U-shaped clip 1. The stretched U-shaped clip 1 can trim the scraps of cloth at different positions on the sewing machine table.

[0051] Reference Figure 3 The telescopic connecting member 2 includes a coil spring 21 fixed on the fixed shaft 5 and a reel 22 located outside the coil spring 21. The inner ring of the coil spring 21 is fixed to the outer wall of the fixed shaft 5, and the outer ring of the coil spring 21 is connected to the inner wall of the reel 22.

[0052] A retractable strip 23 is fixedly attached to the outer wall of the reel 22. The retractable strip 23 is wound around the reel 22, and the end of the retractable strip 23 away from the reel 22 extends through the fixed housing 3 and connects to the U-shaped clip 1. Under normal circumstances, the retractable strip 23 is wound around the reel 22, pulling the U-shaped clip 1 into contact with the outer wall of the fixed housing 3. During use, the operator pulls the U-shaped clip 1 from the outside, which pulls the retractable strip 23 out of the reel 22. At this time, the reel 22 also causes the coil spring 21 to contract, allowing the operator to pull the U-shaped clip 1 to any position for cutting. After cutting is completed, the force applied to the U-shaped clip 1 is released, and the elastic force of the coil spring 21 drives the reel 22 to rotate, thereby rewinding the retractable strip 23 around the reel 22.

[0053] In order to prevent the operator from applying a pulling force on the U-shaped clamp scissors 1 through the telescopic bar 23 when pulling the U-shaped clamp scissors 1 to cut the cloth, thereby affecting the operator's normal cutting work, a one-way ratchet group is also provided on the fixed shaft 5 for limiting the reverse rotation of the coil spring 21.

[0054] Reference Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The one-way ratchet assembly includes an inner gear ring 221 fixed to the inner wall of the reel 22, a one-way tooth 51 is provided on the outer wall of the fixed shaft 5, one end of the one-way tooth 51 is hinged to the outer wall of the fixed shaft 5, and the inner tooth side of the one-way tooth 51 is connected to the spring 54, and the inner tooth side of the one-way tooth 51 is connected to the outer wall of the fixed shaft 5 through the spring 54;

[0055] The fixed shaft 5 is provided with a lever group 52 for releasing the meshing relationship between the one-way teeth 51 and the inner gear ring 221 .

[0056] The rod group 52 includes a pressing head 521, an elastic member 53 fixed between the pressing head 521 and the fixed shaft 5, and a shift rod 523 fixed to the lower end of the pressing head 521. The shift rod 523 is located on one side of the elastic member 53 and the side wall of the end of the shift rod 523 away from the pressing head 521 abuts against the fixed shaft 5. A protrusion 524 is fixed on one side of the shift rod 523. The side of the protrusion 524 facing the one-way tooth 51 is wedge-shaped, and the inclined surface of the wedge faces the side away from the pressing head 521. Normally, the projection 524 is located above one side of the one-way tooth 51. When the mating relationship between the one-way tooth 51 and the inner gear ring 221 needs to be released, the pressing head 521 is directly pressed, which squeezes the elastic member 53 and drives the lever 523 downward. At this time, the wedge-shaped inclined surface of the projection 524 abuts the outer arc surface of the one-way tooth 51. As the projection 524 continues to slide, the projection 524 abuts the one-way tooth 51 and rotates inward about the hinge axis with the fixed shaft 5, thereby releasing the mating relationship between the one-way tooth 51 and the inner gear ring 221. At this time, the tension applied to the U-shaped clamp 1 is released, and the elastic force of the coil spring 21 drives the reel 22 to rotate in the opposite direction, thereby winding the telescopic strip 23 around the reel 22 and resetting the U-shaped clamp 1.

[0057] It is understood that the spring 54 located between the fixed shaft 5 and the one-way tooth 51 is normally compressed, abutting the one-way tooth 51 to always be located within the inner gear ring 221. Due to the limited space between the fixed shaft 5 and the inner gear ring 221, the one-way tooth 51, once located within the inner gear ring 221 under the abutment of the spring 54, will not rotate away from the spring 54. When the protrusion 524 drives the one-way tooth 51 to rotate inward, it further compresses the spring 54. When the U-shaped clip 1 is reset and the force applied to the pressing head 521 is released, the pressing head 521 is reset under the elastic force of the elastic member 53. At this time, the one-way tooth 51 also rotates outward under the elastic force of the spring 54 until the tooth top of the one-way tooth 51 abuts the corresponding tooth groove of the inner gear ring 221, thereby achieving reset. The elastic member 53 can also be a spring.

[0058] The cam 523 is pressed against the locking cam 524 to release the locking cam 523, and the cam 524 is pressed against the locking cam 524, so that the cam 523 is not loosened and the cam 524 is not loosened.

[0059] Reference Figure 8 An output port 31 is provided on the fixed housing 3 , and the telescopic strip 23 passes through the output port 31 to the outside of the fixed housing 3 . A damping group 32 is installed at the output port 31 .

[0060] The damping group 32 includes a mounting sleeve 321 mounted on the inner wall of the output port 31, an elastic sleeve 322 mounted on the inner wall of the mounting sleeve 321, and a damping sleeve 323 mounted on the inner wall of the elastic sleeve 322. The elastic sleeve 322 controls the shape change of the damping sleeve 323 located therein. The middle part of the damping sleeve 323 is for the telescopic strip 23 to pass through. The penetration width of the damping sleeve 323 is smaller than that of the telescopic strip 23 to damp and clamp the telescopic strip 23, thereby achieving the sliding of the damping telescopic strip 23 and causing the telescopic strip 23 to move slowly inside the damping sleeve 323.

[0061] Reference Figure 9 and Figure 10 There can be multiple telescopic connectors 2, and the multiple telescopic connectors 2 are spaced apart along the length direction of the fixed axis 5. The end of each telescopic connector 2 corresponds to the U-shaped clip 1 one by one, so as to realize the telescopic recovery of the multiple U-shaped clips 1 in different directions.

[0062] It can be understood that there are also multiple protrusions 524 set on the shift rod 523, and the multiple protrusions 524 are arranged at intervals along the length direction of the shift rod 523. The multiple protrusions 524 correspond one-to-one to the one-way teeth 51 on the multiple reels 22, and the shift rod 523 is located between the multiple coil springs 21 and the fixed shaft 5, so that the shift rod 523 will not affect the normal winding work of the coil spring.

[0063] Reference Figure 11 A snap-fit ​​U-ring 4 is installed at the bottom of the fixed shell 3. When in use, the snap-fit ​​U-ring 4 can be clamped on the sewing machine table to fix the fixed shell 3. The setting of the snap-fit ​​U-ring 4 makes it possible to fix the fixed shell 3 at any position on the sewing machine table as needed, and installation and disassembly are very convenient.

[0064] Reference Figure 11 An opening is provided on the side of the fixed shell 3 away from the clamping U ring 4, and a ruler cover 6 is installed at the opening. When in use, the telescopic connector 2 can be installed in the fixed shell 3 from the opening, and the ruler cover 6 can be removed to facilitate the installation and maintenance of its internal components.

[0065] The implementation principle of the second embodiment of the present application is as follows: the operator fixes the fixed shell 3 together with the telescopic connecting member 2 placed in the fixed shell 3 on the sewing machine table. When in use, the operator directly pulls the U-shaped clamp 1, and the U-shaped clamp 1 can drive the telescopic strip 23 to be pulled out from the reel 22 and drive the reel 22 to rotate. At this time, the reel 22 will drive the coil spring 21 to contract, and the one-way tooth 51 will slide in the inner gear ring 221; when the operator pulls the U-shaped clamp 1 to the set position, releases the tension applied to the U-shaped clamp 1, and the one-way tooth 51 will abut against the inner gear ring 221, thereby preventing the reel 22 from rotating in the opposite direction. The operator can use the U-shaped clamp 1 to cut the fabric at different positions. After cutting is completed, the pressing head 521 is directly pressed to drive the lever 523 to move inward. At this time, the protrusion 524 will abut the one-way teeth 51 and rotate inward, squeezing the spring 54, thereby releasing the mating relationship between the one-way teeth 51 and the inner gear ring 221. At this time, under the elastic force of the coil spring 21, the reel 22 can be automatically driven to rotate, thereby rewinding the telescopic strip 23 around the reel 22 and pulling the U-shaped clip 1 to the fixed housing 3. When the U-shaped clip 1 is reset, the force applied to the pressing head 521 is released. Under the elastic force of the elastic member 53, the pressing head 521 drives the lever 523 to reset. At this time, the protrusion 524 is released from the abutment relationship with the inner gear ring 221. The one-way teeth 51 are reset under the elastic force of the spring 54 and re-engage in the inner gear ring 221.

[0066] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
