[0012] A further improvement is that: the worm is provided with a handle, and the handle is located outside the base.

[0013] By adopting the above technical solution, the beneficial effects of the utility model are:

[0014] The structure is simple and easy to carry. When transporting, the wheels extend out of the sliding slots to support the base, allowing staff to push the umbrella directly to move it, making it easier to carry. After transporting, the wheels can be retracted into the base to ensure stable placement. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 The utility model is a structural schematic diagram of a parasol with a movable base according to an embodiment of the present invention. DETAILED DESCRIPTION

[0016] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0017] refer to Figure 1 The embodiment of the utility model discloses: a parasol with a movable base, comprising an umbrella body 1, a middle rod 2 arranged on the umbrella body 1, and a base 3, the end of the middle rod 2 is arranged on the base 3, a sliding groove 4 is opened on the base 3, a sliding plate 5 is slidingly provided in the sliding groove 4, four moving wheels 6 are evenly distributed on the sliding plate 5, and a sliding device for driving the moving wheel 6 to slide out of the sliding groove 4 is provided in the base 3.

[0018] Specifically, the sliding device includes a rectangular sliding rod 7, the base 3 is provided with a sliding channel, the sliding channel is connected to the sliding groove 4, the sliding rod 7 is slidably arranged in the sliding channel, a screw 8 is rotatably penetrated in the base 3, one end of the screw 8 is located in the sliding channel, the screw 8 is threadedly driven with the sliding rod 7, the other end of the screw 8 is provided with a worm gear and a worm 11, the base 3 is provided with a rotation channel 10, the screw 8 is located in the rotation channel 10, the worm gear is sleeved on the screw 8, the worm 11 is rotatably penetrated on the base 3, one end of the worm 11 is meshed with the worm gear for transmission, and the other end of the worm 11 passes through the base 3. When the umbrella is to be moved, the worm 11 is rotated, the worm 11 drives the worm gear to rotate, the worm gear drives the screw 8 to rotate, the screw 8 is threadedly driven with the sliding rod 7, so that the sliding rod 7 slides out of the sliding channel, and then drives the sliding plate 5 to slide down, so that the moving wheel 6 slides out of the sliding groove 4, and then the user can push the umbrella to move, making it more convenient to move the umbrella. When the movement is completed, the worm 11 is reversed, so that the screw 8 is reversed, and the sliding rod 7 is returned to its original position. The sliding rod 7 drives the sliding plate 5 to return to its original position, so that the moving wheel 6 is returned to the sliding groove 4, and then the bottom surface of the base 3 contacts the ground, so that the base 3 can be stably placed on the ground, which makes it easier for users to hold the umbrella better.

[0019] In order to prevent excessive sliding, the base 3 is provided with a limit block 9 at the exit of the sliding groove 4, and the sliding plate 5 resists the limit block 9 after sliding downward.

[0020] To further facilitate the transport of the umbrella, a connecting passage 12 is formed around the base 3. A water inlet pipe 13 is provided at the upper end of the base 3, which is provided with a first sealing cap. A water outlet pipe 14 is provided on the side of the base 3, which is connected to the connecting passage 12 and is provided with a second sealing cap. Water, sand, or gravel can be poured in or out of the connecting passage 12. When the umbrella is not in use, the connecting passage 12 can be drained out, thereby reducing the weight of the base 3 and making it easier to hold and transport the umbrella.

[0021] In order to better carry the umbrella and the base 3 , a connecting sleeve 15 is provided on the base 3 , and the middle rod 2 is threadedly connected and passed through the connecting sleeve 15 .

[0022] In order to facilitate the rotation of the worm 11 , a handle is provided on the worm 11 , and the handle is located outside the base 3 .
