DETAILED DESCRIPTION

[0021] In order to better understand the purpose, structure and function of the present invention, a lifting parachute of the present invention is further described in detail below with reference to the accompanying drawings.

[0022] As shown in FIG1 , a lifting parachute of the present invention comprises an umbrella column 1 and an umbrella frame 2. A slide 11 is provided on the umbrella column 1, and an inclined rod 12 is hingedly connected to the slide 11. The other end of the inclined rod 12 is mounted in conjunction with the umbrella frame 2. An upper seat 13 is further provided on the umbrella column 1. The upper seat 13 is located above the slide 11 and can move up and down along the umbrella column 1. The upper seat 13 is hingedly connected to an inclined rod 14. The other end of the inclined rod 14 is used to hinge with the inclined rod 12. It also includes a limiting mechanism 3, a linkage mechanism 4 and a moving mechanism 5. The limiting mechanism 3 is used to limit the upper seat 13 to be located at the upper end of the umbrella column 1, the linkage mechanism 4 is used to realize the synchronous movement of the upper seat 13 and the slide 11, and the moving mechanism 5 is used to drive the slide 11 to move up and down along the umbrella column 1; when the umbrella frame 2 is folded, the linkage mechanism 4 realizes the connection between the upper seat 13 and the slide 11, the limiting mechanism 3 completes the limit unlocking of the upper seat, and the moving mechanism 5 drives the slide 11 to continue to move downward and drives the upper seat 13 to move downward along the umbrella column 1, so that the entire umbrella frame 2 moves downward.

[0023] As shown in Figure 2, the limiting mechanism 3 includes a limiting slide 31, a limiting push rod 32, and a locking mechanism 33. The limiting slide 31 is fixedly mounted on one side of the top of the umbrella column 1, located inside the upper seat 13. The limiting slide 31 has a sliding groove 311 that slopes upward from the outside to the inside. The limiting push rod 32 has a top block 321 at its upper end. The top block 321 is slidably connected to the sliding groove 311 and can slide within the sliding groove 311. When the top block 321 is at the bottom of the sliding groove 311, it protrudes from the surface of the umbrella column 1 and abuts the bottom of the upper seat 13, limiting the vertical movement of the upper seat 13. When the top block 321 is at the upper end of the sliding groove 311, it retracts from the surface of the umbrella column 1, allowing the upper seat 13 to slide vertically along the umbrella column 1. The bottom end of the limiting push rod 32 is connected to the locking mechanism 33, which drives the top block 321 to move, thereby opening and unlocking the upper seat 13. The locking mechanism 33 includes a fixed lock seat 331, a pull rod 332, and a pull ring 333. The fixed lock seat 331 is fixedly mounted at the lower end of the umbrella column 1 at a height suitable for manual operation. The upper end of the fixed lock seat 331 is hingedly connected to the inner side of the upper end of the pull rod 332. The lower end of the limiting push rod 32 is hingedly connected to the outer side of the upper end of the pull rod 332. The lower end of the pull rod 332 is fixedly connected to the pull ring 333. In the locked state, the pull rod 332 is in a vertical state. The pull rod 332 and the fixed lock seat 331 are fixedly connected by a lock (not shown in the figure; any lock connection method can be used). The limiting push rod 32 is located at the lowest position on the outer side of the umbrella column 1. When the top block 321 on the limiting push rod 32 is at the bottom end of the slide groove 311, the top block 321 protrudes from the surface of the umbrella column 1 and abuts against the bottom of the upper seat 13, limiting the vertical movement of the upper seat 13. When unlocking, pull the pull ring 333 to separate the pull rod 332 from the fixed lock seat 331. At the same time, the top end of the pull rod 332 and the hinged joint with the limiting push rod 32 move upward, driving the limiting push rod 32 to move upward. With the help of thrust, the limiting push rod 32 can be pushed up and close to the surface of the umbrella column 1. At this time, when the top block 321 on the limiting push rod 32 is at the upper end of the slide groove 311, the top block 321 is retracted into the surface of the umbrella column 1, and the upper seat 13 can slide vertically along the umbrella column 1.

[0024] As shown in Figure 3, the linkage mechanism 4 includes a linkage fixing rod 41, a fixing seat 42 and a pin 43. The linkage fixing rod 41 is vertically fixedly connected to the upper seat 13 and can slide along the umbrella column 1. The fixing seat 42 is fixedly connected to the lower end of the linkage fixing rod 41 and is also fixedly connected to the slide 11. The fixing seat 42 has a socket 1 421 and the diagonal rod 14 has a socket 2 141. When the umbrella stand 2 is folded, the socket 2 141 of the diagonal rod 14 is aligned with the socket 1 421 of the fixing seat 42. The pin 43 is inserted into the socket 1 421 and the socket 2 141 to lock the diagonal rod 14 and the fixing seat 42, thereby realizing the linkage sliding of the umbrella stand 2 with the upper seat 13 and the slide 11.

[0025] As shown in Figure 4, the moving mechanism 5 includes a pulley assembly 51, a synchronous belt 52, and a rocker 53. The synchronous belt 52 is fixed to the umbrella column 1 via the pulley assembly 51. The slide 11 is fixedly connected to the synchronous belt 52. The rocker 53 is used to manually drive the pulley assembly 51 to rotate, driving the synchronous belt 52 to move up and down, thereby driving the slide 11 to move up and down. Because the linkage mechanism 4 realizes the linkage between the umbrella frame 2, the upper seat 13, and the slide 11, the umbrella frame 2 and the upper seat 13 move together with the slide 11, which can achieve the height extension and retraction of the umbrella frame 2, making it more convenient for storage and transportation. Specifically, the pulley assembly 51 includes a driving wheel 511, a driven wheel assembly 1 512, and a driven wheel assembly 2 513. The driving wheel 511 is fixedly mounted in the umbrella column 1 and meshes with the synchronous belt 52. Driven wheel assembly 1 512 includes two driven wheels, one mounted at the top and one at the bottom of the driving wheel 511. The synchronous belt 52 passes through the driven wheels, the driving wheel 511, and the other. Driven wheel assembly 1 512 creates an S-shaped connection between the synchronous belt 52 and the driving wheel 511, strengthening the connection and preventing slippage and deviation. Driven wheel assembly 2 513 is fixedly mounted at the upper and lower ends of the umbrella column 1, respectively. The synchronous belt 52 passes through driven wheel assembly 2 513, enabling vertical movement of the synchronous belt 52. The driving wheel 511's axis, which is exposed on the surface of the umbrella column 1, has a polygonal shape. A remote lever 53 is inserted into the axis to manually rotate the driving wheel 511.

[0026] When in use, first fold the umbrella frame 2, then insert the pin 43 of the linkage mechanism 4 into the second hole 141 of the inclined rod 14 and the first hole 421 of the fixing seat 42 to lock the inclined rod 14 and the fixing seat 42, then pull the pull ring 333 to separate the pull rod 332 from the fixed lock seat 331, and the top block 321 retracts into the surface of the umbrella column 1, unlocking the upper seat 13, and then the rocker 53 drives the entire upper seat 13, the sliding seat 11 and the umbrella frame 2 to move downward to reduce the overall height.

[0027] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
