[0002] Polyester yarn refers to yarn spun with polyester as raw material. Polyester is a type of fiber made by spinning polymers. There are many types of polyester yarn fabrics. In addition to weaving pure polyester fabrics, there are also many products blended or interwoven with various textile fibers to make up for the shortcomings of pure polyester fabrics and give play to better wearing performance.

[0003] The patent document with the existing announcement number CN216444766U discloses a high-strength and high-tenacity polyester yarn, including a top plate, a bobbin and a polyester yarn body, the top of the top plate is provided with an auxiliary structure, the bottom of the top plate is fixed with a bobbin, the bottom of the bobbin is provided with a limiting structure, the surface of the bobbin is provided with a polyester yarn body, and the surface of the polyester yarn body is provided with a reinforcing structure. By providing the auxiliary structure, a positioning column is set up at the center of the top of the top plate. When the polyester yarn is used, the thread end can be wound around the positioning column. After winding, the operator can move the movable sleeve on the positioning column so that the pressing sheet at the bottom is pressed on the polyester yarn, so that the polyester yarn can be pressed on the top plate, so that the thread end of the polyester yarn can be fixed to prevent it from moving. When it is used next time, the operator only needs to move the movable sleeve upwards and pick up the pressed polyester thread end, which is relatively convenient and realizes the convenience of using the polyester yarn.

[0004] Although the high-strength and high-tenacity polyester yarn mentioned above can solve the corresponding technical problems, in order to prevent the thread end from moving, the anti-slip ring is used to press the thread end.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] See also Figure 1-4 The present embodiment provides a polyester thread, comprising a supporting component 1, a polyester thread main body 2 wound on the supporting component 1, a pressing component 3 for pressing the polyester thread main body 2, and a socket component 4 for positioning the pressing component 3. The polyester thread main body 2, the pressing component 3, and the socket component 4 are respectively arranged on the supporting component 1, the pressing component 3 is movably connected to the polyester thread main body 2, the socket component 4 is movably connected to the pressing component 3, and the socket component 4 is respectively provided with one at the top and bottom of the supporting component 1; the pressing component 3 comprises a pressing rod 31, and the top and bottom ends of the pressing rod 31 are movably connected to a shell 32, and a groove 33 adapted to the shell 32 is provided on the supporting component 1, and the shell 32 and the socket component 4 are arranged in a one-to-one correspondence, and the shell 32 is located in the inner cavity of the corresponding socket component 4.

[0025] Working principle: After the polyester thread body 2 is processed and wound on the bobbin 11, the shell 32 is aligned with the groove 33 and inserted, so that the surface of the pressure rod 31 is squeezed by the surface of the polyester thread body 2, so that the pressure rod 31 drives the slider 34 to slide on the surface of the guide rod 36, and the spring 35 is compressed, so that the pressure rod 31 gradually moves away from the center of the bobbin 11 until the shell 32 is completely stuck in the inner cavity of the groove 33, and then the baffle 41 is rotated to the surface of the corresponding limit plate 12, and the baffle 41 plays a positioning role for the shell 32; when the polyester thread body 2 is used for weaving, the polyester thread body 2 is pulled The thread end of the polyester thread main body 2 causes the polyester thread main body 2 to gradually fall off the spool 11, and then the overall diameter of the polyester thread main body 2 wound on the spool 11 gradually becomes smaller. At this time, the elastic restoring force of the spring 35 causes the pressure rod 31 to move toward the center of the spool 11, so that the pressure rod 31 can always contact and press the surface of the polyester thread main body 2, so that after the polyester thread main body 2 is cut, the pressure rod 31 can timely press the thread end of the polyester thread main body 2, which is convenient for finding the thread end when used next time, and effectively prevents the polyester thread main body 2 from loosening.

[0026] Specifically, the support assembly 1 includes a bobbin 11 arranged parallel to the pressure rod 31, and the top and bottom of the bobbin 11 are rotatably connected to a limit plate 12 through a bearing, and the polyester thread body 2 is wound on the surface of the bobbin 11, and the two limit plates 12 are respectively located at the top and bottom of the polyester thread body 2. The above design allows the bobbin 11 and the polyester thread body 2 on its surface to rotate, so the polyester thread body 2 can be rotated off the bobbin 11 by pulling the thread end of the polyester thread body 2.

[0027] Specifically, one groove 33 is provided on each stop plate 12, and the housing 32 is movably clamped to the inner cavity of the corresponding groove 33. The above design can realize the detachable connection between the wire pressing assembly 3 and the support assembly 1, which is convenient for the subsequent disassembly and assembly of the wire pressing assembly 3 according to actual use requirements.

[0028] Specifically, the polyester thread main body 2 includes an inner core layer 21 arranged on the thread barrel 11, and a medium elastic layer 22 is provided on the surface of the inner core layer 21, and an outer covering yarn layer 23 is provided on the surface of the medium elastic layer 22. The medium elastic layer 22 is blended by polyester yarn and viscose fiber, and has high strength and resilience, which further improves the toughness of the inner core layer 21. The outer covering yarn layer 23 is a filament bundle or a filament double twisted yarn, which can ensure the flatness of the cloth woven by the polyester thread main body 2, and the inner core layer 21 is made of polyester thread material.

[0029] Specifically, the inner cavity of the housing 32 is slidably connected with a slider 34, and the end of the pressure rod 31 facing the slider 34 is rotatably connected to the corresponding slider 34 through a bearing. The above design realizes the movable connection between the pressure rod 31 and the housing 32 through the slider 34, so that the pressure rod 31 can move along the length direction of the housing 32, and further enables the pressure rod 31 to adjust its position according to the use of the polyester thread body 2 on the surface of the support component 1.

[0030] Specifically, a spring 35 is fixedly connected to one side of the slider 34 and the inner wall surface of the housing 32. The above design can automatically reset the slider 34 through the elastic restoring force of the spring 35, which can not only realize the automatic position adjustment of the pressure rod 31 without manual operation, but also enable the slider 34 to drive the pressure rod 31 to press tightly on the surface of the polyester thread body 2 to prevent the polyester thread body 2 from loosening.

[0031] Specifically, a guide rod 36 is provided inside the slider 34, both ends of which are fixedly connected to the inner wall of the housing 32, and the spring 35 is sleeved on the surface of the guide rod 36. The above design can guide the slider 34, so that the slider 34 can stably slide in the inner cavity of the housing 32, and prevent the slider 34 from slipping out of the inner cavity of the housing 32; at the same time, it can also limit the spring 35, so that the reverse elastic force generated by the spring 35 when compressed can always be in the same straight line with the direction of the pressure, and avoid the spring 35 from being skewed.

[0032] Specifically, the sleeve assembly 4 includes a cover 41 threadedly sleeved on the limit plate 12, and a through hole 42 is opened at the center of the cover 41, and the inner wall surface of the through hole 42 contacts the housing 32. With the above design, by screwing the sleeve assembly 4 onto the limit plate 12, the housing 32 on the limit plate 12 can be positioned, effectively preventing the wire pressing assembly 3 from being separated from the support assembly 1.

[0033] Specifically, a curved surface is provided on the side of the groove 33 away from the bobbin 11, and the curved surface is in the same straight line as the central axis of the limiting plate 12, and the curved surface contacts the inner wall surface of the blocking cover 41. The above design effectively ensures that the housing 32 can be placed in the inner cavity of the groove 33 and the blocking cover 41, and when the sleeve assembly 4 is placed on the limiting plate 12, the curved surface can contact the inner wall surface of the blocking cover 41, thereby further preventing the housing 32 from shaking in the inner cavity of the groove 33.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
