Detailed Description

The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown.

Referring to fig. 1-6, the present invention provides an automatic lifting system 42 for a stand chair, comprising: a waterproof containing box body 1 which is a hollow structure with an opening at the upper end; the cover body 2 is hinged to the upper side end of the waterproof containing box body 1 and is used for covering the upper end opening of the waterproof containing box body 1; the lifting device 3 is arranged in the waterproof accommodating box body 1; and the seat device 4 is arranged in the waterproof containing box body 1 in a liftable mode and is connected with the lifting device 3, the lifting device 3 controls the lifting of the seat device 4, so that the seat device 4 is contained in the waterproof containing box body 1 or extends out of the waterproof containing box body 1, the structure is simple, the operation is convenient, the seat device 4 can be contained in the waterproof containing box body 1 when the seat device is not used, the seat 42 is prevented from being aged due to long-term wind and sunshine, water cannot be accumulated on the seat 42, and the seat 42 is convenient to clean and maintain.

The lifting device 3 comprises a column support 31, a tensile rope 32, a rope support seat 33, a driving piece 34 and a lifting connecting plate 35, the column support 31 is fixedly arranged on the inner wall of the waterproof accommodating box body 1, the rope support seat 33 and the driving piece 34 are respectively arranged at two ends of the column support 31, the lifting connecting plate 35 is slidably arranged on the column support 31, the lifting connecting plate 35 is used for installing the seat device 4, the tensile rope 32 is wound on the rope support seat 33, the tensile rope 32 is connected with the lifting connecting plate 35 and the driving piece 34, and the driving piece 34 drives the tensile rope 32 to move so as to drive the lifting connecting plate 35 to lift. The tensile cord 32 may be a steel wire cord and the drive member 34 may be a motor.

The lifting device 3 further comprises a protective cover 36, and the protective cover 36 is arranged at the upper end of the upright support 31 and used for protecting the lifting device 3. Because the protection device is arranged in the waterproof containing box body 1 along the vertical direction, the protection cover 36 can prevent water from entering the lifting device 3, and the use safety and the service life of the lifting device 3 are ensured.

The seat device 4 includes a support base 41 and a plurality of seats 42, the plurality of seats 42 are arranged in a row on the support base 41, and the support base 41 is mounted on the lifting connection plate 35.

The supporting seat 41 is provided with a pedal 411 for stepping on, so that the sitting comfort is good, and the accidental falling can be prevented.

The waterproof containing box body 1 is also provided with a drainage structure for preventing water accumulation, and water entering the waterproof containing box body 1 from the edge gap of the cover body 2 can be discharged in time.

In one embodiment, the drainage structure includes a groove 11, a drainage hole 12 and a drainage channel 13, the groove 11 is disposed along the circumference of the upper end edge of the waterproof housing case 1, the drainage hole 12 is disposed at the bottom of the groove 11, and the drainage channel 13 communicates the drainage hole 12 and the waterproof housing case 1. Wherein, the groove 11 is arranged corresponding to the edge of the cover body 2, so that the water entering from the edge gap of the cover body 2 can directly fall into the groove 11.
