[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-5 As shown, the utility model provides a technical solution: a yarn mouth structure of a knitting machine, including a Us seat 1, and a group of first guide wheels 2 are installed on the back of the Us seat 1. When the device is in use, the first guide wheel 2 is installed inside the guide rail of the knitting machine. The set first guide wheel 2 can facilitate the device to move left and right along the guide rail of the knitting machine.

[0026] A slide groove 3 is provided on the front of the Us seat 1, and a groove 4 is provided on the inner wall of the slide groove 3. A spring 5 is provided inside the groove 4, and the bottom end of the spring 5 abuts against the inner bottom wall of the groove 4. The inner bottom wall of the groove 4 is fixedly connected with a limiting ring 13, and the limiting ring 13 is located outside the spring 5. The limiting ring 13 is set to limit the bottom end of the spring 5 to prevent the bottom end of the spring 5 from sliding.

[0027] A top frame 6 is provided above the spring 5, and the inner top wall of the top frame 6 abuts against the top end of the spring 5. The upper surface of the top frame 6 abuts against a pressure plate 7, and the upper surface of the pressure plate 7 abuts against the inner top wall of the groove 4. The outer surfaces of the pressure plate 7 and the top frame 6 are both slidably connected to the inner wall of the groove 4, and the front end of the pressure plate 7 is fixedly connected to the Us handle 8. The spring 5 can give the top frame 6, the pressure plate 7 and the Us handle 8 an upward pushing force.

[0028] The outer surface of the Us handle 8 is slidably connected to the inner wall of the slide 3. A second guide wheel 11 is installed at the top of the Us handle 8, and a yarn mouth 12 is installed at the bottom of the Us handle 8. An inspection cover assembly 9 is provided inside the Us handle 8. The inspection cover assembly 9 includes a through hole 901. The through hole 901 is opened inside the Us handle 8. The rear end of the through hole 901 corresponds to the position of the groove 4. A blocking cover 904 is installed inside the through hole 901. The blocking cover 904 can be used to shield and protect the spring 5.

[0029] A first card slot 902 is provided on the inner bottom wall of the through hole 901, and a card plate 905 is fixedly connected to the bottom end of the blocking cover 904. The card plate 905 is engaged with the inside of the first card slot 902. The bottom end of the blocking cover 904 can be fixed by engaging the card plate 905 with the first card slot 902.

[0030] A second card slot 903 is provided on the inner top wall of the through hole 901, and the top of the blocking cover 904 is fixedly connected with a spring piece 906. The outer surface of the spring piece 906 is fixedly connected with a card block 907, and the card block 907 is engaged with the inside of the second card slot 903. By engaging the card block 907 with the second card slot 903, the top of the blocking cover 904 can be fixed.

[0031] When the blocking cover 904 needs to be opened, press the spring piece 906 downward, and the spring piece 906 will drive the card block 907 to move downward. When the card block 907 is out of the second card slot 903, pull the spring piece 906 outward to pull the top of the blocking cover 904 out of the through hole 901. Then pull the spring piece 906 upward to remove the blocking cover 904, so that the blocking cover 904 can be opened.

[0032] An L-shaped pull plate 908 is provided at the rear of the blocking cover 904, and the rear end of the L-shaped pull plate 908 is fixedly connected to the front of the top frame 6. The L-shaped pull plate 908 can be used to easily pull the top of the top frame 6 and the top of the spring 5 out from the inside of the groove 4.

[0033] A group of limit assemblies 10 are arranged between the Wusi handle 8 and the Wusi seat 1. The positions of the two limit assemblies 10 correspond to each other. The limit assembly 10 includes a limit plate 101. The end of the limit plate 101 close to the Wusi handle 8 does not extend to the front of the baffle 904 to avoid affecting the opening of the baffle 904. The internal thread of the limit plate 101 is connected with a group of bolts 102. The rear ends of the two bolts 102 pass through the limit plate 101 and extend to the interior of the Wusi seat 1, and the bolts 102 are threadedly connected to the Wusi seat 1. By utilizing the threaded connection between the bolts 102 and the Wusi seat 1, the limit plate 101 can be fixed to the rear of the Wusi seat 1. The set limit plate 101 can limit the Wusi handle 8 to prevent the Wusi handle 8 from sliding out of the inside of the slide groove 3.

[0034] Working principle: When the device is in use, the downward pressure mechanism on the knitting machine can push the second guide wheel 11, the Us handle 8 and the yarn mouth 12 to move downward. The spring 5 provided can drive the Us handle 8 and the yarn mouth 12 to reset. When the device is used for a long time and the spring 5 needs to be replaced, press the spring piece 906 downward, and the spring piece 906 will drive the block 907 to move downward. When the block 907 is out of the second slot 903, pull the spring piece 906 outward to pull the top end of the blocking cover 904 out of the through hole 901, and then pull the spring piece 906 upward to remove the blocking cover 904, so that the blocking cover 904 can be opened. Then, pull the L-shaped pull plate 908 forward. The movement of the L-shaped pull plate 908 can drive the top frame 6 and the top end of the spring 5 to move out of the interior of the groove 4, so that the spring 5 can be easily removed from the device, and then the spring 5 can be easily replaced after the device has been used for a long time.
