[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment: Refer to Figures 1-4 A yarn guide plate convenient for assembly shown in the figure, including a movable support 1, a sleeve 8 and a yarn guide hook 2. The movable support 1 is installed on the sleeve 8. A threaded hole 9 communicating with the inner cavity of the sleeve 8 is provided on the sleeve 8. The yarn guide hook 2 is installed on the movable support 1. An upper positioning ring 3 and a lower positioning ring 4 are arranged at intervals on the installation surface of the movable support 1. The outer diameter of the upper positioning ring 3 is adapted to the U-shaped clamping part of the yarn guide hook 2. The U-shaped clamping part of the yarn guide hook 2 is located between the upper positioning ring 3 and the lower positioning ring 4 and contacts the outer wall of the upper positioning ring 3. The end of the U-shaped clamping part of the yarn guide hook 2 is inserted into the positioning hole 7 provided on the movable support 1. It further includes a limiting member 6; the limiting member 6 includes a U-shaped rod 61. Elastic snap rings 62 are fixedly installed at both ends of the U-shaped rod 61. Annular clamping grooves adapted to the elastic snap rings 62 are provided on the inner ring walls of the upper positioning ring 3 and the lower positioning ring 4. The U-shaped rod 61 is provided with a baffle 63, and the baffle 63 is located between the U-shaped clamping part of the yarn guide hook 2 and the lower positioning ring 4.

[0024] When assembling the yarn guide hook 2 and the movable bracket 1, one end of the U-shaped clamping portion of the yarn guide hook 2 can be inserted into the positioning hole, and the inner wall of the U-shaped clamping portion is in contact with the outer wall of the upper positioning ring 3. At this time, both ends of the U-shaped rod 61 are respectively inserted into the inner ring cavities provided on the upper positioning ring 3 and the lower positioning ring 4, and through the clamping of the elastic snap ring 62 and the annular slot, the U-shaped rod 61 is fixed to the upper positioning ring 3 and the lower positioning ring 4 respectively. At this time, the baffle 63 provided on the U-shaped rod 61 is located between the U-shaped clamping portion of the yarn guide hook 2 and the lower positioning ring 4. The baffle 63 forms a limit for the U-shaped clamping portion of the yarn guide hook 2. Through the cooperation of the baffle 63 and the upper positioning ring 3, the yarn guide hook 2 can be prevented from moving up and down, left and right. By cooperating with the insertion of one end of the U-shaped clamping portion into the positioning hole 7, the yarn guide hook 2 can be prevented from moving along the insertion direction of the U-shaped rod 61. At the same time, the contact between the outer wall of the upper positioning ring 3 and the inner wall of the U-shaped clamping portion of the yarn guide hook 2 can prevent the yarn guide hook 2 from rotating around the axis of the insertion end of the U-shaped clamping portion, which can effectively ensure the stability of the assembly of the yarn guide hook 2 and the movable bracket 1. When disassembly is required, the U-shaped rod 61 can be directly pulled out from the movable bracket 1. The assembly and disassembly operations are convenient and fast, greatly improving work efficiency.

[0025] It should be noted that: the positioning hole 7, the upper positioning ring 3 and the lower positioning ring 4 are integrally provided with the movable bracket 1.

[0026] As a preferred implementation manner in this embodiment, as Figure 4 shown, the movable bracket 1 is provided with a plugging groove 5 adapted to the end of the baffle 63. The end of the baffle 63 away from the U-shaped rod 61 is located in the plugging groove 5. The inner bottom surface of the plugging groove 5 can support one end of the baffle 63, and the other end of the baffle 63 is fixed on the U-shaped rod 61, which can enhance the support strength of the baffle 63 for the yarn guide hook 2 and avoid the baffle 63 being bent and damaged due to the excessive extrusion of the yarn guide hook 2 on the baffle 63 (that is, the longitudinal force of the yarn guide hook 2 forms extrusion on the baffle 63).

[0027] As a preferred implementation manner in this embodiment, as Figure 3 shown, the baffle 63 is arranged as an arc-shaped plate, and the concave surface of the arc-shaped plate is adapted to the outer surface of the U-shaped clamping portion of the yarn guide hook 2. Its arc-shaped setting can increase the contact area between the baffle 63 and the outer wall of the U-shaped clamping portion of the yarn guide hook 2, so that the extrusion of the yarn guide hook 2 on the baffle 63 can be dispersed, and the baffle 63 is evenly stressed everywhere, which can prevent the baffle 63 from being damaged by extrusion.

[0028] As a preferred implementation manner in this embodiment, as Figure 3 shown, a pull ring 64 is installed on the U-shaped rod 61, and the U-shaped rod 61 can be pulled through the pull ring 64 to separate it from the movable bracket 1, which is convenient for the disassembly of the U-shaped rod 61 and the movable bracket 1.

[0029] As a preferred implementation manner in this embodiment, not shown in the figure, the elastic snap ring 62 is made of metal rubber material, which has the inherent properties of the selected metal and the elasticity similar to that of rubber. It is not afraid of high temperature of 800° and low temperature of minus 167°. At the same time, it has good wear resistance, corrosion resistance and anti-aging property, and its service life is much better than that of ordinary rubber materials.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
