DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figures 1-5 As shown, the locking structure of this outdoor umbrella includes a pillar 1, an umbrella frame 7, and a diagonal pull rod 4 connecting the pillar 1 and the umbrella frame 7. It also includes a sliding assembly 6 and a locking caliper 62 mounted on the pillar 1. The sliding assembly 6 includes a sliding sleeve 61, a stop block 63, a rotating moving rod 64, and a rotating guide seat 65. The sliding sleeve 61 is slidably fitted onto the pillar 1, and the end of the diagonal pull rod 4 is rotatably connected to the sliding sleeve 61. The sliding sleeve 61 has a moving cavity, and the stop block 63 and the rotating moving rod 64 are sequentially slidably disposed within the moving cavity. The stop block 63 is fixed to the rotating moving rod 64, or the stop block 63 and the rotating moving rod 64 are integrally formed. A linkage device is provided between the locking caliper 62 and the stop block 63, whereby the locking caliper 62, under external force, causes the stop block 63 to press against or disengage from the pillar 1, locking or unlocking the engagement between the sliding sleeve 61 and the pillar 1. The linkage device includes a first guide slope 66 located on one side of the stop block 63 and a second guide slope 67 located on one side of the locking caliper 62. Specifically, the first guide slope 66 is located on the rotating moving rod 64, and the second guide slope 67 is located on the rotating guide seat 65, with the second guide slope 67 in close contact with the first guide slope 66. The rotating guide seat 65 is fixed to the locking caliper 62, or the rotating guide seat 65 and the locking caliper 62 are integrally formed. When the locking caliper 62 is rotated, the rotating guide seat 65 rotates synchronously. Guided by the first guide slope 66 and the second guide slope 67, the rotating moving rod 64 moves laterally, causing the stop block 63 to press against or disengage from the column 1, thereby locking or unlocking the engagement between the sliding sleeve 61 and the column 1, thus achieving the positioning of the tilt angle of the inclined rod 4 and the umbrella frame 7.

[0026] In the above technical solution: multiple contact protrusions are evenly distributed on the first guide slope 66 and the second guide slope 67. The contact protrusions increase the friction when the first guide slope 66 and the second guide slope 67 come into contact, ensuring that the rotary guide seat 65 can only rotate relative to the rotary moving rod 64 under the action of external force, and preventing the rotary guide seat 65 from rotating accidentally, which would cause the sliding sleeve 61 to be accidentally unlocked or locked.

[0027] In the above technical solution: the rotating moving rod 64 has two sets of first guide inclined surfaces 66, the two sets of first guide inclined surfaces 66 have opposite inclination directions, and a first step 68 is formed between the two sets of first guide inclined surfaces 66. The rotating guide seat 65 has two sets of second guide inclined surfaces 67, and a second step 69 is formed between the two sets of second guide inclined surfaces 67. During the rotation of the rotating guide seat 65, when the second step 69 contacts the first step 68, the rotating guide seat 65 stops rotating. At this time, the stop block 63 disengages from the column 1, and the sliding sleeve 61 can move up and down relative to the column 1.

The handle 612 is used to exert force to make the sliding sleeve 61 move up and down relative to the stand 1, and the handle 612 makes the sliding more labor-saving. The cooperation of the second screw 615 and the arc-shaped groove 621 limits the rotation process of the locking calipers 62, prevents the locking calipers 62 from rotating excessively, and prevents the stand 1 from being deformed due to excessive extrusion of the anti-skid block 63.
