In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments can have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, and therefore, once an item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0019] Example 1: Figures 1 to 6 As shown, a horizontal spool locking mechanism includes a handwheel 5, a housing 6, a sliding sleeve 9, a top shaft 14 and a top 12; The top 12 is matched with the inner hole of the spool; the top 12 is installed on the shaft end of the top shaft 14, and the top shaft 14 is axially limited and rotated in the sliding sleeve 9; The sliding sleeve 9 includes a first axial diameter portion 9-1 and a second axial diameter portion 9-2 connected to each other. The outer diameter of the first axial diameter portion is smaller than the outer diameter of the second axial diameter portion. A first limiting step is formed at the connection between the first axial diameter portion and the second axial diameter portion. The hand wheel 5 is sleeved on the outer periphery of the first shaft diameter portion and is connected to the sleeve 9 through a flat key 3 with clearance fit; the housing 6 is slidably mounted on the outer periphery of the second shaft diameter portion of the sleeve 9 with clearance fit; An external gear 6-1 is provided on the outer periphery of the first end of the housing 6; an internal gear 5-1 that matches the external gear is provided on the side of the handwheel 5 close to the housing 6; a helical groove 6-2 that communicates with the outer wall of the sleeve 9 is provided on the wall of the housing 6, and a roller bearing 16 is connected and installed on the outer wall of the sleeve 9 corresponding to the helical groove, so that the sleeve 9 rotates forward or backward in the housing 6 under the guidance of the roller bearing 16 and the helical groove 6-2, so as to drive the top 12 to move axially to tighten the I-wheel.

[0020] In the present application, the outer diameter of the sleeve is slightly smaller than the inner hole of the housing, and the sleeve is intermittently fitted so that it can slide flexibly.

[0021] In this embodiment, Figure 3 As shown, one end of the housing 6 is machined with an external gear 6-1, the gear module m is 0.8, and the number of teeth is 138. A half-circle helical groove 6-2 is machined on the wall of the housing 6, and the helix angle α is less than 10°. A small helix angle can ensure a certain degree of self-locking. Figure 2 As shown, the housing 6 has countersunk holes on its ribs and is fixed to a bracket 7 using six second screws 8, wherein the bracket 7 can be part of a stranding machine or can be connected and fixed to the stranding machine. The countersunk holes are machined on the housing ribs to facilitate the fixing of the housing.

[0022] In some embodiments, the horizontal I-shaped wheel locking mechanism also includes an elastic compression member 4, which is compressed at the end of the handwheel 5 away from the outer shell 6 and is used to push the handwheel 5 close to the outer shell 6 under the pressure of the elastic compression member 4, so that the outer gear 6-1 is engaged with the inner gear 5-1, thereby locking the handwheel 5 to prevent the sleeve 9 from sliding.

[0023] Furthermore, the horizontal I-shaped wheel locking mechanism also includes a spring pressure cover 2, which is connected to the end of the first axial diameter portion of the sleeve 9; the handwheel 5 has a circle of grooves outside the inner hole on one side close to the spring pressure cover 2 for installing the elastic compression part 4, and one end of the elastic compression part 4 is limitedly installed in the groove, and the other end is compressed and fixed by the spring pressure cover 2.

[0024] In this embodiment, the elastic compression member 4 is a compression spring.

[0025] In this embodiment, a tapered roller bearing 15 and a deep groove ball bearing 17 are positioned between the tip shaft 14 and the sleeve 9. The deep groove ball bearing 17 is axially restrained by a brake washer 19 and a round nut 20. The tip 12 is connected to the tip shaft 14 via a flat key 13. The tip 12's maximum outer diameter is axially restrained by a tip gland 11, which is mounted on the end of the second axial diameter 9-2 of the sleeve 9. The tip shaft and tip are mounted inside the sleeve via the tapered roller bearing 15 and deep groove ball bearing 17, allowing for flexible rotation. This allows the tip 12 to lock the horizontal spool, preventing axial movement, while allowing the tip shaft and tip to rotate with the spool.

[0026] In this embodiment, the maximum outer diameter portion of the tip 12 is connected to the tip gland 11 via a labyrinth sealing structure to prevent foreign matter from entering the interior.

[0027] In this embodiment, the tip 12 is conical with a cone angle of 60 degrees, and the structure matches the inner hole of the spool. During operation, as the sleeve moves forward, the tip 12 presses against the inner hole of the spool.

[0028] In this embodiment, there are multiple deep groove ball bearings 17, and spacers 18 are provided between the multiple deep groove ball bearings.

[0029] In this embodiment, Figure 3 、 Figure 4 As shown, the outer circumference of the second diameter portion of the sleeve 9 is threaded, mounting a set of roller bearings 16. The outer diameter of the roller bearings 16 is slightly smaller than the width of the helical groove 6-2 in the outer shell wall. Guided by the helical groove, the sleeve 9 rotates forward or backward within the outer shell 6. A flat keyway is machined on the outer circumference of the first diameter portion of the sleeve 9 for mounting a flat key 3 for connecting to the handwheel 5. Three first screws 1 are used to mount the spring gland 2 on the end face.

[0030] like Figure 5 、 Figure 6 As shown, the outer ring of the handwheel 5 has several protrusions. On the side of the inner hole near the spring gland 2, there is a circle of elastic member mounting grooves 5-2, which are used to mount the elastic compression member 4. A keyway 5-3 is machined into the inner hole for mounting the flat key 3. The handwheel 5 is connected to the sleeve 9 via the flat key 3, with a clearance fit. On the side of the handwheel 5 near the housing 6, there is a circle of internal gears 5-1, whose tooth profile matches that of the external gear 6-1 of the housing 6.

[0031] During operation, grab the hand wheel 5 and pull it outwards, the inner gear 5-1 and the outer gear 6-1 are separated and rotated counterclockwise, driving the sliding sleeve 9 to rotate together and move backward relative to the housing 6, as shown in FIG. Figure 7 After the spool is placed in the designated position, turn the hand wheel 5 clockwise to move the center 12 forward and tighten the spool. Figure 2As shown, under the action of the elastic compression member 4, the internal gear 5-1 of the hand wheel 5 is engaged with the external gear 6-1 of the housing 6 to lock the I-shaped wheel.

[0032] The present application provides a horizontal spool locking mechanism which has a simple structure, is easy to operate, is stable and reliable, and can effectively lock the horizontal spool.
