Description

Technical Field

[0001] The utility model relates to a rotating mechanism, in particular to a steering knuckle, and to an umbrella with the steering knuckle. Background Art

[0002] At present, fishing umbrellas, sun umbrellas and other umbrellas are generally equipped with a steering knuckle mechanism, so as to adjust the direction of the umbrella body according to the direction of the sun. However, after the angle of the umbrella body is adjusted, due to the heavy weight of the upper umbrella body, or the influence of wind force, plus the lever effect, it is very necessary to keep the angle of the umbrella body stable and not shaking. Prior art 1 (CN216493908U) discloses a steering adjustable fishing umbrella bracket, which has a movable tooth 11 and an engagement block 22, and the lower end of the engagement block 22 has a spring. The movable tooth 11 and the engagement block 22 are kept fixed in the axial direction by the elastic force of the spring when locked. When unlocking is required, the engagement block 22 moves downward under the drive of the outer cover 22. This structure relies on the elastic force of the spring when locking, but since the spring itself can be deformed, the locking effect of the movable tooth 11 is not good. If the weight of the umbrella body above the movable tooth 11 is relatively large, it can compress the spring itself, so that the movable tooth shakes. In the prior art, it is proposed to add a locking nut to prevent the sliding seat from moving, which is more stable than the spring. Obviously, such a structure is too complicated and time-consuming and laborious when unlocking is required. Prior art 2 (CN220529464U) discloses a fishing umbrella elbow, which also uses the elastic force of the first spring 4 to axially press the meshing teeth 31 on the slider 3 and the convex joint 11 to achieve the purpose of locking, but shaking still occurs. Prior art 3 (CN220384461U) discloses a fishing umbrella adjustment accessory, in which the adjustment part 111 and the locking part 301 are meshed, and the locking is completed by the mutual cooperation of the gear and the rack, which cannot completely solve the problem of shaking of the steering part 100.

[0010] Furthermore, a countersunk hole for accommodating the end of the spring is provided on the inner side of the handle.

[0011] Further, the distance between the outer sides of the handles of the first jaw part and the second jaw part is substantially the same as the width of the ear part.

[0025] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] See also Figure 1-7The steering knuckle 1 of the utility model comprises a first connecting part 2, a second connecting part 3, a locking part 4, a spring 5, a first pin 6, and a second pin 7. The first connecting part 2 comprises a first connecting rod 21 and a gear 22. The first connecting rod 21 is fixedly connected to the gear 22. The first connecting rod 21 is located above the gear 22. The gear 22 has an axial hole 23 in the middle. The axis of the axial hole 23 is perpendicular to the axis of the first connecting rod 21.

[0027] The locking part 4 has a first jaw part 41 and a second jaw part 42. The first jaw part 41 and the second jaw part 42 respectively include a meshing part 43, a handle 44, and a bearing 45. The meshing part 43 is fixed above the handle 44. The meshing part 43 includes a plurality of latch teeth 431. The bearing 45 is located inside the handle 44 and below the meshing part 43. The axes of the bearing holes 451 on the bearings of the first jaw part 41 and the second jaw part 42 coincide. The bearing surfaces of the bearings of the first jaw part 41 and the second jaw part 42 cooperate with each other, so that the locking part 4 as a whole forms a clamp-shaped structure.

[0028] See also Figure 1 The width of the bearing 45 on the second jaw part 42 is approximately half of the width of the second jaw part 42. Similarly, the width of the bearing 45 on the first jaw part 41 is approximately half of the width of the first jaw part 41. The two bearings are offset from each other in the width direction. Since the axes of the bearing holes 451 on the bearings of the first jaw part 41 and the second jaw part 42 coincide, the bearing surfaces can fit each other. It can be understood by those skilled in the art that, except Figure 1 In addition to the design in which the two bearing surfaces fit each other, one of the bearings can also be distributed at both ends of the width direction of the clamp, forming a gap in the middle to accommodate the other bearing to form a matching relationship.

[0029] The second connecting part 3 includes a base 31, and two ears 32 are arranged opposite to each other above the base 31, and a gap 33 is formed between the two ears 32. A second connecting rod 38 is provided below the base 31. A partition 34 is also provided above the base 31 and in the gap 33. The width of the partition is smaller than the width of the gap 33, so as to provide space for the rotation of the handle. The partition 34 is provided with a receiving hole 35 for receiving the spring 5. The axis of the receiving hole 35 is perpendicular to the axis of the shaft hole 23.

[0030] The ear portion 32 is provided with a first hole 36 and a second hole 37, wherein the first hole 36 is arranged above the second hole 37, the axis of the first hole 36 coincides with the axis of the shaft hole 23, the gear 22 is located in the gap 33, and the first connecting portion 2 can rotate relative to the second connecting portion 3 around the axis of the first hole 36; the axis of the second hole 37 coincides with the axis of the bearing hole 451 of the bearing 45, and the first clamp portion 41 and the second clamp portion 42 can rotate relative to the second connecting portion 3 around the axis of the second hole 37; the latching teeth 431 of the first clamp portion 41 and the second clamp portion 42 can lock the gear 22 from both sides.

[0031] exist Figure 1-2 In the embodiment, the first hole 36 and the second hole 37 are through holes, the first pin 6 passes through the first hole 36 and the shaft hole 23, and the second pin 7 passes through the second hole 37 and the bearing hole 451. Those skilled in the art will appreciate that the first hole and the second hole may also be countersunk holes.

[0032] The working process of the utility model is as follows: when it is necessary to adjust the angle between the first connecting part 2 and the second connecting part 3, pinch the lower ends of the two handles 44 by hand to overcome the elastic force of the spring 5, and the two meshing parts 43 open. At this time, rotate the first connecting rod 21 to deviate from the second connecting rod 38 by a certain angle. After adjusting the angle, release the handle 44. Under the action of the spring, the handle 44 clamps the gear 22 with the two meshing parts 43 to fix the angle.

[0033] The utility model provides meshing parts 43 on both sides of the gear 22, and meshes the teeth 431 on the meshing parts with the teeth of the gear 22 by elastic force, which can effectively avoid the shaking problem of the first connecting part. Figure 5 As shown, assuming that the gear 22 rotates counterclockwise, the second jaw 42 on the right side of the gear 22 will be pushed to the right, which may cause it to loosen, but at the same time, the first jaw 41 on the left side will be driven by the gear 22 to be closer to the gear 22, thereby increasing the locking force. This design is equivalent to the first jaw 41 and the second jaw 42 forming an "interlocking" effect with the gear 22. Compared with the prior art, it well avoids the problem of the first connecting part shaking during use.

[0034] Secondly, since a pliers-like working principle is adopted, the opening angle of the meshing portion 43 can be adjusted by controlling the strength of the hand, so that when the control gear 22 rotates, there is a certain contact with the meshing portion 43 to form damping, thereby preventing the first connecting portion 2 from rotating too quickly (for example: when the first connecting portion 2 is connected to the umbrella body, the umbrella body is too heavy or is affected by the wind and rotates quickly by itself, especially when the first connecting portion has been adjusted to a relatively large angle, its gravitational torque is greater).

[0035] In addition, the bearing surfaces of the bearings of the first jaw portion 41 and the second jaw portion 42 of the utility model cooperate with each other, so that the locking portion 4 as a whole forms a clamp-shaped structure, so that the volume of the entire locking portion 4 is greatly reduced, and the distance between the outer sides of the handles of the first jaw portion 41 and the second jaw portion 42 is substantially the same as the width of the ear portion (see Figure 3 , Figure 5 ), so that the entire locking portion is basically located in the gap 33, further, the gear 22 is designed below the first connecting portion 2, so that from the overall point of view, the entire steering knuckle is similar to the structure of a column (see Figure 2 ), not only makes the whole steering knuckle more beautiful, but also allows the first connecting rod 21 and the second connecting rod 38 to be basically on the same axis. Compared with the design of the first connecting rod 21 and the second connecting rod 38 being misaligned in the prior art, when the first connecting rod 21 and the second connecting rod 38 are both in a vertical state, it is more conducive to maintaining balance.

[0036] In order to facilitate the operator to exert force when pinching the handle 44, the width of the lower two sides of the ear 32 is gradually reduced to form a notch 322, which is adapted to the design of the two handles and is used to place the operator's fingers. This can easily increase the stroke of the handle 44 and facilitate the rapid opening of the two engaging parts 43.

[0037] When the first connecting rod 21 is rotated, a boss 24 is further provided between the first connecting rod 21 and the gear 22, and an arc surface 321 is formed on the upper part of the ear 32, and the top end of the arc surface 321 abuts against the lower end surface of the boss 24, which, on the one hand, provides support force for the first connecting part 2, and on the other hand, makes the structure of the entire steering knuckle more compact. In addition, when the first connecting rod 21 rotates, the boss 24 will not be hindered due to the existence of the arc surface 321.

[0038] Those skilled in the art will appreciate that the receiving holes 35 on the partition 34 may also be replaced by countersunk holes arranged on both sides, with a spring arranged in each countersunk hole. Preferably, a countersunk hole for accommodating the end of the spring is provided on the inner side of the handle to prevent the spring from sliding.

[0039] Figure 8 It is a schematic diagram of an umbrella of the utility model, which includes a lower umbrella rod 10, an upper umbrella rod 9, an umbrella body 8, and a steering knuckle 1. The umbrella body 8 is connected to the upper umbrella rod 9, the upper umbrella rod 9 is fixedly connected to the first connecting rod 21, and the lower umbrella rod 10 is fixedly connected to the second connecting rod 38. In this way, the upper umbrella rod 9 rotates relative to the lower umbrella rod through the steering knuckle 1, thereby adjusting the direction of the umbrella body 8.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
