As shown in the above drawings and fig. 14 to 18, each roof rack unit 2 includes a first roof bar 21, a second roof bar 22, a diagonal brace 24, and a joint 25, respectively. The top frame comprises a plurality of extension bars 23, each top frame unit 2 being connected to an extension bar 23. Wherein the inner end of the extension rod 23 is pivotally connected to the top frame unit 2 to allow the extension rod 23 to be flipped up relative to the top frame unit 2 when the umbrella frame 100 is tipped over sideways. The inner end of the first ejector rod 21 is rotatably connected to the top cap 3; the joint 25 is disposed at the outer end of the first ejector rod 21, and the two are fixedly connected or integrally disposed. The inner end of the second ejector rod 22 is rotatably connected to the first slider 4, and the outer end of the second ejector rod 22 is rotatably connected to the joint 25. The inner end of the extension rod 23 is rotatably connected to the joint 25, and the outer end is extended outwards and may be provided with a connection piece 26, and the connection piece 26 is provided with a connection hole or a connection groove, so as to facilitate connection with the umbrella cloth 200 and the like, and provide a larger shielding area. The upper end of the diagonal brace 24 is rotatably connected to the first jack 21, and the lower end of the diagonal brace 24 is rotatably connected to the second slider 5. In the embodiment, the first ejector rod 21 of each top frame unit 2 is pivotally connected to the top cap 3, the second ejector rod 22 of each top frame unit 2 is pivotally connected to the first slider 4, and the diagonal brace 24 of each top frame unit 2 is pivotally connected to the second slider 5. As shown in fig. 12, the extension rod 23 is connected to the joint 25 through a first pivot a1, the second jack 22 is connected to the joint 25 through a second pivot a2, and the first jack 21, the second jack 22, the center support rod 1 and the first slider 4 thereon of each jack unit 2 constitute a crank slider mechanism; the first carrier rod 21, the diagonal brace 24, the central support rod 1 and the second slide 5 thereon of each top frame unit 2 constitute a crank slide mechanism.

Further, in the present embodiment, each top frame unit 2 includes two second ejector pins 22, and the two second ejector pins 22 are connected between the same joint 25 and the first slider 4 in parallel to enhance the strength of the top frame unit 2. A gap is arranged between the two second ejector rods 22, and the diagonal brace 24 passes through the gap between the two second ejector rods 22 and is respectively connected with the first ejector rod 21 and the second sliding block 5. The length of the diagonal brace 24 is smaller than that of the first ejector rod 21 and the second ejector rod 22, and the distance between the joint of the diagonal brace 24 and the first ejector rod 21 and the outer end of the first ejector rod 21 is smaller than one half of the length of the first ejector rod 21, and the sum of the distance and the length of the diagonal brace 24 is smaller than or equal to the length of the second ejector rod 22. In addition, the difference in length between the first jack 21 and the second jack 22 is less than one tenth of the length of the second jack 22; preferably, the length of the first ejector pin 21 is smaller than the length of the second ejector pin 22. When the umbrella stand 100 is in the folded state, the diagonal brace 24 is accommodated between the two second ejector rods 22 in each top frame unit 2, so that the internal space is fully utilized, and the overall volume after folding is prevented from being excessively large.

Specifically, the joint 25 of each top frame unit 2 and the center support rod 1 (specifically, the lower end portion of the uppermost sub rod 11) are close to each other, that is, the outer end portion of the first jack 21, the outer end portion of the second jack 22, and the diagonal brace 24 and the extension rod 23 are all close to the center support rod 1; the first slider 4 and the second slider 5 are separated from each other and slide upwards until they are close to the top cap 3, and the spring 6 is compressed; the inner end of the second jack 22 and the inner end of the first jack 21 are close to each other.

When the umbrella stand 100 is folded, the lugs 411 on the two locking plates 41 are pressed inwards, the second sliding block 5 moves downwards and the first sliding block 4 are separated from each other, the inclined supporting rod 24 is driven to be close to the central supporting rod 1, and therefore the first ejector rod 21 and the second ejector rod 22 lean against the central supporting rod 1 at the same time, and the first sliding block 4 is pushed upwards and the top cap 3 is pushed to be close; finally, the extension rod 23 is turned upwards to be close to the first ejector rod 21, and the folding of the bracket is completed. When the shielding product is opened, the extension rod 23 is turned downwards to open, the second sliding block 5 is pushed upwards, and meanwhile, the first sliding block 4 slides downwards under the auxiliary pushing of the restoring force of the spring 6 until the locking plate 41 is inserted into the second sliding block 5, each top frame unit 2 is completely unfolded, and the whole top frame unit is directly locked in an unfolded state.

The umbrella stand 100 of the present embodiment can be applied to outdoor shielding products such as beach umbrellas, and when the shielding products are fallen to the ground, the extension rod 23 is turned upwards to buffer the impact force, so that the strength of the support is improved, and the top frame unit 2 does not need to be deformed or folded. The umbrella frame 100 can be unfolded and folded, and the folded volume is small. Wherein, the number of the second ejector rods 22 of each top frame unit 2 is two, so that the overall strength of the top frame is improved, and the size of the folded umbrella frame 100 is not increased. In addition, the spring 6 between the top cap 3 and the first slider 4 provides assistance when the umbrella stand 100 is opened, and the product is more labor-saving when opened. Except for the extension rod 23, the whole top frame unit 2 is linked with the first sliding block 4 and the second sliding block 5, so that the opening and the folding are convenient; the extension rod 23 is pivoted on the joint 25, when the product falls down, the extension rod 23 can be folded upwards to buffer impact, so that the end part of the extension rod 23 is prevented from being directly impacted, and the risk of breakage or deformation of the extension rod 23 is reduced.
