[0023] Combined with appendix Figures 1 to 5 As shown, this embodiment discloses an automatic hand crank simulation opening and closing test device for outdoor sun umbrellas, including a transmission column 1, an automatic hand crank mechanism 2, at least one first longitudinal positioning part 3, a base 5, and an umbrella column 7. The bottom end of the transmission column 1 is fixed on the base 5, and a transmission rack 11 is provided on the outer side of the transmission column 1. The automatic hand crank mechanism 2 and the first longitudinal positioning part 3 are arranged vertically and fitted on the transmission column 1, and can move freely longitudinally on the transmission column 1. The automatic hand crank mechanism 2 includes an automatic hand crank part 21, which can drive the umbrella column crank 71 to rotate, thereby testing the umbrella column crank 71. A transverse positioning part 4 is provided on the first longitudinal positioning part 3, and the umbrella column 7 is fixed on the transverse positioning part 4 and can move laterally.

[0024] In conjunction with the above installation structure, the first longitudinal positioning part 3 includes a handle 31, a locking part 32, and a first connecting sleeve part 33. The handle 31 and the locking part 32 are disposed on the outer side of the first connecting sleeve part 33. The first connecting sleeve part 33 is fitted onto the transmission column 1. The locking part 32 matches the transmission rack 11. In this embodiment, the locking part 32 is a compression lock. In other embodiments, a commonly used locking and limiting structure can also be used. When the locking part 32 is in the unlocked state, the user can hold the handle 31 and apply a pulling force in the longitudinal direction to allow the first longitudinal positioning part 3 to move freely longitudinally on the transmission column 1. When the locking part 32 is in the locked state, the bottom of the locking part 32 and the serrated part of the transmission rack 11 abut against each other to achieve fixed limiting, so that the first longitudinal positioning part 3 can be fixed on the transmission column 1.

[0025] In conjunction with the above installation structure, the transverse positioning part 4 includes a fixed plate part 43 and a sliding sleeve part 42. The end of the fixed plate part 43 is fixed to the inner side of the first longitudinal positioning part 3 with bolts. The sliding sleeve part 42 is fitted onto the fixed plate part 43 and can move laterally along the fixed plate part 43. The sliding sleeve part 42 is provided with a plurality of fastening parts 41. The fastening part 41 includes two fastening plates 411. The fastening plates 411 are fixedly connected by bolts. The fastening plates 411 are recessed inward and form a cavity 412 in the middle. The cavity 412 of different fastening parts 41 is of different sizes to accommodate umbrella columns 7 with different diameters. The umbrella column 7 can be placed in the cavity 412 and clamped and fastened by the fastening plates 411.

[0026] With the above installation structure, users can freely adjust the fixed position and height of the umbrella column 7 and clamp and fix the umbrella column 7, ensuring the stability of the umbrella column 7 during testing, preventing the umbrella column 7 from moving randomly or even falling over during testing, and reducing the error during testing.

[0027] In summary, the automatic crank unit 21 includes a rotating shaft 211, a rotating arm 212, and a rotating handle 213. The two ends of the rotating arm 212 are respectively matched and connected to the rotating shaft 211 and the rotating handle 213. The rotating shaft 213 is provided with a slot, and one end of the rotating arm 212 is in the slot and can extend and retract freely. The rotating arm 212 is also marked with a scale, so it can be used for outdoor umbrellas with different lengths of umbrella column cranks 71. The rear of the rotating shaft 211 is connected to a first motor 214, which allows the rotating shaft 211 to rotate and the rotating handle 213 to rotate. The rotating handle 213 is provided with a receiving cavity 215, and the umbrella column crank 71 is placed in the receiving cavity 215, thereby driving the umbrella column crank 71 to rotate. The umbrella column crank 71 is provided with an opening rope (not shown in the figure), thereby simulating the opening and closing of the umbrella.

[0028] In conjunction with the above installation structure, the automatic hand crank mechanism 2 also includes a second connecting sleeve 22 and a second longitudinal positioning part 23. The second connecting sleeve 22 is fitted onto the transmission column 1 and connects the automatic hand crank part 21 and the second longitudinal positioning part 23. The automatic hand crank mechanism 2 moves longitudinally on the transmission column 1 through the second longitudinal positioning part 23. The second longitudinal positioning part 23 includes a transmission gear 231, several sliding wheels 232, and a second motor 233. The transmission gear 231 is meshed with the transmission rack 11. The center of the transmission gear 231 is connected to the rotating shaft of the second motor 233. The second motor 233 can make the transmission gear 231 rotate and move longitudinally on the transmission rack 11. The sliding wheels 232 are located inside the second connecting sleeve 22 and contact the transmission column 1 to assist sliding, making the automatic hand crank mechanism 2 move more smoothly in the longitudinal direction, and also providing a certain support for the second longitudinal positioning part 23.

[0029] In addition to the above, several casters are also provided under the base 5, which improves the mobility of this utility model, makes it easier to move this utility model, and makes it convenient to adjust the test angle before testing.

[0030] In addition to the above, this utility model is also equipped with a central control system 8, which can control the first motor 214 and the second motor 233 and display the test results.

[0031] Compared with the prior art, this utility model has the following advantages: it can be applied to outdoor umbrellas with different umbrella column diameters and crank mechanism specifications, and can clamp and fix the umbrella column to prevent the outdoor umbrella from falling over during the test, thus improving the stability during the test; the positions of each component of the testing device can be freely adjusted, enhancing the practicality of the testing device.
