Although the present invention is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative, not limiting, of the scope of the present invention.

[0023] See Figure 1-4 In one embodiment of the present invention, an assembled parasol steering structure includes: a knob 1, a fixing seat 2, a connecting rod 3, a positioning cylinder 4, a locking cylinder 5, an umbrella pole connecting seat 6, a parasol locking assembly 7, a mounting cylinder 8, a protective sleeve 9 and a spring 10. The tail end of the connecting rod 3 is fixed to the inner side of the umbrella pole connecting seat 6; the fixing seat 2, the positioning cylinder 4 and the locking cylinder 5 are sleeved on the connecting rod 3, wherein the connecting rod 3 is loosely matched with the positioning cylinder 4 and the fixing seat 2, the positioning cylinder 4 is fixedly connected to the fixing seat 2, and the locking cylinder 5 is fixed to the inner side of the head end of the umbrella pole connecting seat 6. The tail end of the positioning cylinder 4 and the head end of the locking cylinder 5 are both provided with teeth that can mesh with each other. The knob 1 is connected by a thread The connection is arranged at the head end of the connecting rod 3 and abuts against the head end of the fixing seat 2 to expand or reduce the distance between the positioning cylinder 4 and the locking cylinder 5 so that the positioning cylinder 4 and the locking cylinder 5 are engaged or disengaged. The parasol locking assembly 7 is arranged at the tail end of the umbrella pole connecting seat 6 to fasten the parasol to the umbrella pole connecting seat 6; the mounting cylinder 8 is fixed to the outer periphery of the fixing seat 2 by screws, and is used for connecting this steering structure with the ground fixing part; the protective sleeve 9 is arranged on the umbrella pole connecting seat 6 to protect the umbrella pole; the spring 10 is arranged on the connecting rod 3 and is located between the fixing seat 2, the positioning cylinder 4, and the locking cylinder 5 to facilitate the separation between the positioning cylinder 4 and the locking cylinder 5.

[0024] Specifically, the fixing seat 2 is a cylindrical structure, and an outer groove 22 is provided at the tail end thereof, and an inner groove 21 is provided on the bottom wall of the outer groove 22, and the inner diameter of the inner groove 21 is smaller than the inner diameter of the outer groove 22; the positioning cylinder 4 is fixed in the inner groove 21 and the tail end of the positioning cylinder 4 is at least partially located on the inner side of the outer groove 22. After such an arrangement, the positioning cylinder 4 and the fixing seat 2 are connected as one, and can move synchronously. During production, the positioning cylinder 4 and the fixing seat 2 are processed separately to reduce the degree of integration of the steering structure; in this embodiment, the outer periphery of the positioning cylinder 4 and the groove wall of the inner groove 21 are tightly fitted to each other, that is, an interference connection.

[0025] In one embodiment, in order to ensure that the rear positioning cylinder 4 will not rotate around its own axis alone after being assembled with the fixing seat 2, the positioning cylinder 4 and the fixing seat 2 can be bonded; alternatively, the inner groove 21 is a square structure, and the outer periphery of the positioning cylinder 4 is also a square structure. After assembly, the positioning cylinder 4 will not slide relative to the fixing seat 2.

[0026] The head end of the umbrella pole connecting seat 6 is a cylindrical structure, and the axis center of the head end of the umbrella pole connecting seat 6 is provided with a accommodating cavity 61, and the outer peripheral end of the head end of the umbrella pole connecting seat 6 is provided with an inserting groove 62; the locking cylinder 5 is fixed in the accommodating cavity 61. During implementation, the locking cylinder 5 and the umbrella pole connecting seat 6 are interference connected or bonded, the purpose of which is to integrate the locking cylinder 5 and the umbrella pole connecting seat 6; the setting of the inserting groove 62 reduces the outer diameter of the head end of the umbrella pole connecting seat 6. After assembly, the head end of the umbrella pole connecting seat 6 can be at least partially inserted into the outer groove 22, and the side wall of the outer groove 22 abuts against the outer periphery of the umbrella pole connecting seat 6. Such a structure can effectively prevent dust from entering the inner side of the steering structure, thereby ensuring the performance of its components.

[0027] A limiting plate 31 is provided at the tail end of the connecting rod 3, and a limiting groove 51 that is adapted to the size of the limiting plate 31 is opened at the tail end of the locking cylinder 5. The locking cylinder 5 is sleeved on the connecting rod 3, and the limiting plate 31 is located in the limiting groove 51. The limiting plate 31 is bonded to the bottom wall of the accommodating cavity 61.

The tail end of the spring 10 abuts against the bottom wall of the central groove 52, and the head end abuts against the bottom wall of the inner groove 21. That is to say, after assembly, when the positioning cylinder 4 is engaged with the locking cylinder 5, the parasol is fixed in the direction, and the spring 10 is compressed between the locking cylinder 5 and the fixing seat 2. Because the positioning cylinder 4 is fixed to the fixing seat 2, the spring 10 is compressed between the locking cylinder 5 and the fixing seat 2. Then, the spring 10 has a tendency to release potential energy to separate the positioning cylinder 4 from the locking cylinder 5. When the knob 1 is rotated back toward the head end of the connecting rod 3, the positioning cylinder 4 and the fixing seat 2 are pushed away from the locking cylinder 5 under the action of the spring 10, and the positioning cylinder 4 is disengaged from the locking cylinder 5. At this time, the direction of the parasol can be changed by rotating the umbrella pole connecting seat 6. After adjusting the direction of the parasol, the knob 1 is rotated toward the tail end of the connecting rod 3 again until the positioning cylinder 4 is engaged with the locking cylinder 5, and the direction adjustment of the parasol is completed.

[0029] The parasol locking assembly 7 includes a locking wrench 71, a locking force adjusting rod 72 and a pin 73. The locking wrench 71 is fixedly connected to the locking force adjusting rod 72 through the pin 73; the tail of the umbrella pole connecting seat 6 is set as a hook-shaped tightening part, the locking force adjusting rod 72 is connected to the tightening part, and the locking wrench 71 is press-fitted with the tightening part. Rotating the locking wrench 71 can change the size of the tightening part opening, thereby achieving the purpose of tightening; the protective cover 9 is arranged on the inner side of the tightening part.

[0030] Through this technical solution, a knob, a fixing seat, a positioning cylinder, a locking cylinder, and an umbrella pole connecting seat are arranged on the connecting rod, wherein the positioning cylinder is fixedly connected to the fixing seat, and the locking cylinder is fixedly arranged on the inner side of the head end of the umbrella pole connecting seat, and the tail end of the positioning cylinder and the head end of the locking cylinder are both provided with teeth that can engage with each other. The design of dispersed parts makes this steering structure have the advantages of easy processing, assembly and replacement.
