[0025] 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 of 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.

[0026] like Figure 1 , Figure 2 and Figure 6 As shown, it is a steering gear according to an embodiment of the utility model, comprising: a first connector 100, a second connector 200 and a nut pressing block 300;

[0027] The first end of the first connector 100 is arranged close to the second connector 200, and a rotation groove 101 is provided on the end surface of the first end of the first connector 100, and the rotation groove 101 runs from one side of the first connector 100 to the other side, and at least one side of the first end of the first connector 100 is provided with an inclined support surface 110, and the inclined support surface 110 is located on both sides of the rotation groove 101, and the inclined support surface 110 gradually inclines toward a direction away from the second connector 200 from one end close to the middle of the first connector 100 to one end close to the edge of the first connector 100;

[0028] The second end of the second connecting head 200 is arranged close to the first connecting head 100, and the end face protrusion of the second end of the second connecting head 200 is provided with a threaded rod 210, and the end of the threaded rod 210 away from the second connecting head 200 is connected to the side wall of the rotating groove 101 through the supporting shaft 610, and the nut clamping block 300 is provided with a threaded hole 301, and the threaded rod 210 is penetrated into the threaded hole 301, and the side wall of the threaded hole 301 is threadedly connected with the threaded rod 210, and the nut clamping block 300 abuts against the end face of the first end of the first connecting head 100 or the inclined supporting surface 110 when rotating along the threaded rod 210.

[0029] In this embodiment, the first connector 100 and the second connector 200 can rotate relative to each other. Specifically, the central axis of the threaded rod 210 coincides with the central axis of the second connector 200. In this way, when the threaded rod 210 rotates relative to the first connector 100, the second connector 200 also rotates with the threaded rod 210. In one embodiment, the cross section of the second connector 200 is circular, the second connector 200 is cylindrical, and the threaded rod 210 is cylindrical. The circumferential surface of the threaded rod 210 is at least partially provided with a threaded structure for threading with the side wall of the threaded hole 301 of the nut pressing block 300.

[0030] In this embodiment, the cross section of the first connector 100 is circular, that is, the first connector 100 is arranged in a cylindrical shape, and the first end of the first connector 100 is provided with an inclined support surface 110, and the inclined support surface 110 is adjacent to and connected to the end surface of the first end of the first connector 100, and the inclined support surface 110 is inclined to the radial plane of the first connector 100. In this way, when the threaded rod 210 rotates, it will drive the nut clamping block 300 to rotate relative to the first connector 100, so that the side of the nut clamping block 300 facing the first connector 100 is parallel to the inclined support surface 110, and then, as shown in Figure 2 and Figure 6 As shown, the nut pressing block 300 is screwed toward the inclined support surface 110, and the nut pressing block 300 is tightened to abut against the inclined support surface 110. The friction between the nut pressing block 300 and the inclined support surface 110 will fix the angle between the threaded rod 210 and the first connector 100. Conversely, when it is necessary to adjust the angle of the second connector 200 relative to the first connector 100, the nut pressing block 300 is screwed in the opposite direction, so that the nut pressing block 300 rotates along the thread structure of the threaded rod 210 and moves away from the first connector 100 along the axial direction of the threaded rod 210, so that the threaded rod 210 and the first connector 100 can rotate relative to each other, as shown in FIG. Figure 1As shown, if the central axes of the first connector 100 and the second connector 200 need to coincide so that the umbrella handle stands upright, the threaded rod 210 is rotated to align with the axis of the first connector 100, and then the nut pressing block 300 is tightened to abut against the end surface of the first end of the first connector 100, so that the first connector 100 and the second connector 200 are fixed. In this way, the umbrella handle including the diverter can be adjusted to an upright or bent state.

[0031] In the above embodiment, when the angle needs to be adjusted, the nut clamping block 300 is twisted in a direction away from the first connecting head 100, and then the angle of the threaded rod 210 in the rotating groove 101 is adjusted, and then the nut clamping block 300 is twisted in the opposite direction so that the nut clamping block 300 abuts against the inclined support surface 110, and the nut clamping block 300 is tightened. The friction between the nut clamping block 300 and the inclined support surface 110 fixes the angle between the threaded rod 210 and the first connecting head 100, thereby realizing the angle adjustment between the first connecting head 100 and the second connecting head 200. Compared with the snap-on fixation, the nut clamping block 300 is used for loosening and fixing, the structure is simpler, and the angle adjustment process is more convenient.

[0032] It is worth mentioning that the threaded rod 210 and the side wall of the rotating groove 101 can be rotatably connected in the following manner: Figure 3 and Figure 4 As shown, the end of the threaded rod 210 away from the second connector 200 is provided with a first rotation hole (not shown) in the radial direction, and the side walls on both sides of the rotation groove 101 are provided with second rotation holes 102 respectively, and the support shaft 610 is inserted into the second rotation hole 102 and the first rotation hole. The support shaft 610 can be a pin, so that the threaded rod 210 can rotate relative to the support shaft 610 to achieve rotation in the rotation groove 101. In one embodiment, the end of the threaded rod away from the second connector is provided with support shafts protruding radially toward both sides, and the side walls on both sides of the rotation groove are provided with second rotation holes respectively, and the support shafts on both sides of the threaded rod are rotatably provided in the two second rotation holes. In one embodiment, the side walls on both sides of the rotation groove are provided with support shafts protruding radially, and the end of the threaded rod away from the second connector is provided with a first rotation hole in the radial direction, and the support shaft is rotatably inserted in the first rotation hole.

[0033] In order to make the angle adjustment of the steering gear more flexible, in one embodiment, the inclined support surfaces 110 are respectively provided on both sides of the first end of the first connector 100, and the two inclined support surfaces 110 are respectively provided at the two ends of the extension direction of the rotation groove 101. In this embodiment, the first end of the first connector 100 is provided with two inclined support surfaces 110, and the two inclined support surfaces 110 are respectively provided at the two ends of the extension direction of the rotation groove 101, so that the nut clamping block 300 can rotate to the two ends of the rotation groove 101 with the threaded rod 210, and respectively abut against the two inclined support surfaces 110 at the two ends, so that the steering gear has more adjustable angles and more flexible adjustment.

[0034] In order to make the angle adjustment of the steering gear more flexible, in one embodiment, as Figure 5 As shown, the inclined support surface 110 includes a first inclined surface 111 and a second inclined surface 112, the first side of the first end of the first connector 100 is provided with the first inclined surface 111, and the second side of the second end of the first connector 100 is provided with the second inclined surface 112. In one embodiment, the angle between the first inclined surface 111 and the end surface of the first end of the first connector 100 is a first angle, the angle between the second inclined surface 112 and the end surface of the first end of the first connector 100 is a second angle, and the first angle is not equal to the second angle. In this embodiment, the inclination angles of the first inclined surface 111 and the second inclined surface 112 are different, which can support the second connector 200 to be fixed at different angles, so that the steering gear has more adjustable angles and more flexible adjustment. In one embodiment, the first angle is 45° and the second angle is 60°. In this way, the first connector 100 and the second connector 200 can be bent at 120 degrees or 135 degrees to adapt to different sun exposure angles. The umbrella handle that is bent at 120 degrees or 135 degrees can adapt to more conventional sun exposure angles and has stronger adaptability.

[0035] In order to facilitate the tightening and force application of the nut pressing block 300, in one embodiment, a first friction pattern structure is provided on the outer surface of the nut pressing block 300. For example, the first friction pattern structure is provided as stripes. In this embodiment, the nut pressing block 300 is provided in a cylindrical shape. By providing the first friction pattern structure on the circumferential surface of the nut pressing block 300, when the user holds the circumferential surface of the nut pressing block 300 and twists the nut pressing block 300, the friction between the user's hand and the nut pressing block 300 is effectively increased, thereby making it more convenient for the user to apply force. In one embodiment, the cross-sectional shape of the outer edge of the nut pressing block 300 is a polygon, for example, the cross-sectional shape of the outer edge of the nut pressing block 300 is a hexagon or an octagon. By setting the cross-sectional shape of the outer edge of the nut pressing block 300 to a polygon, it is convenient for the user to apply force to the nut pressing block 300 and to twist the nut pressing block 300.

[0036] In order to better support the umbrella, in one embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, it also includes a first support rod 400 and a second support rod 500. The first support rod 400 is connected to one end of the first connector 100 away from the second connector 200, and the second support rod 500 is connected to one end of the second connector 200 away from the first connector 100.

[0037] In this embodiment, the first support rod 400 is coaxially arranged with the first connecting head 100, and the second support rod 500 is coaxially arranged with the second connecting head 200. When the first connecting head 100 and the second connecting head 200 rotate relative to each other, the first support rod 400 and the second support rod 500 also rotate relative to each other, so that the bending angle of the umbrella handle is adjusted.

[0038] In order to achieve the connection between the first connector 100 and the first support rod 400, in one embodiment, please combine Figure 3 , Figure 4 and Figure 6 , the first connector 100 is protruded at one end away from the second connector 200 and is provided with a first connecting portion 130, one end of the first support rod 400 is sleeved on the first connecting portion 130, and the first connecting portion 130 is connected to the first support rod 400 through a first pin 410. In this embodiment, please combine Figure 3 , Figure 4 and Figure 6The first connecting portion 130 is radially provided with a first fixing hole 131, the first support rod 400 is cylindrically arranged, the first support rod 400 is provided with a second fixing hole along the radial direction, and the first pin shaft 410 is inserted into the first fixing hole 131 and the second fixing hole, thereby realizing the connection between the first connecting head 100 and the first support rod 400.

[0039] In order to realize the connection between the second connector 200 and the second support rod 500, in one embodiment, please combine Figure 3 , Figure 4 and Figure 6 The second connecting head 200 is provided with a second connecting portion 230 protruding from one end of the second connecting head 200, one end of the second supporting rod 500 is sleeved on the second connecting portion 230, and the second connecting portion 230 is connected to the second supporting rod 500 through a second pin 510. In this embodiment, please combine Figure 3 , Figure 4 and Figure 6 The second connecting portion 230 has a third fixing hole 231 radially opened, the second support rod 500 is cylindrically arranged, the second support rod 500 has a fourth fixing hole radially opened, and the second pin shaft 510 is inserted into the third fixing hole 231 and the fourth fixing hole, thereby realizing the connection between the second connecting head 200 and the second support rod 500.

[0040] In one embodiment, the length of the first support rod 400 is greater than the length of the second support rod 500. In this embodiment, the first support rod 400 is used to support the ground, and the second support rod 500 is used to connect with the umbrella frame and the umbrella canopy. Since the length of the first support rod 400 is longer, it is conducive to better supporting the second support rod and the umbrella frame. In addition, the height of the relative rotation position of the first support rod and the second support rod is made higher, which is conducive to better shielding the user.

[0041] In order to make the angle of the steering gear more firmly fixed, in one embodiment, the nut clamping block 300 is provided with a second friction pattern structure on one side facing the first connector 100. For example, the second friction pattern structure is provided as stripes, and the extension direction of each stripe is provided in a reflective shape with the center of the nut clamping block 300 as the center of the circle, for example, the second friction pattern structure is provided as a wave pattern, for example, the second friction pattern structure is provided as a spiral pattern. In this embodiment, by providing the second friction pattern structure on one side of the nut clamping block 300 facing the first connector 100, the friction force between the nut clamping block 300 and the end face of the first end of the first connector 100 and the inclined support surface 110 can be increased, so that after the nut clamping block 300 is tightened, the angle of the steering gear is more firmly fixed.

[0042] In order to make the angle fixation of the steering gear more secure and reduce the wear between the nut clamping block 300 and the first connector, in one embodiment, a buffer friction pad is provided on the side of the nut clamping block 300 facing the first connector 100, and the material of the buffer friction pad is rubber. In this embodiment, the nut clamping block 300 is abutted against the end face or inclined support face of the first connector through the buffer friction pad. The buffer friction pad can make the nut clamping block 300 and the first connector have a greater friction force and can provide a buffer between the two. In this way, the angle fixation of the steering gear can be made more secure and the wear between the nut clamping block 300 and the first connector can be reduced. It is worth mentioning that the buffer friction pad can be replaced. For example, after the support shaft is removed from the first connector, the buffer friction pad that is severely worn or damaged can be replaced.
