DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] For example, see Figure 1-3 A building elevator with a protective structure comprises a base 1, the top of the base 1 is slidably connected with a lifting seat 3 through a sliding rod 2, the front end of the lifting seat 3 is provided with an opening 4, the front end of the lifting seat 3 is slidably connected with a protective door 5, the top of the base 1 is connected with the lifting seat 3 by a lifting device 6, the front end of the lifting seat 3 is provided with an automatic opening and closing mechanism 7, the top of the protective door 5 is provided with a warning mechanism 8, the automatic opening and closing mechanism 7 comprises a hydraulic bin 71, a gear 77, and a rack 78, the hydraulic bin 71 is fixedly connected to the bottom of the base 1 through a connecting plate, the internal piston at one end of the hydraulic bin 71 is slidably connected with a pressure rod 72, the end of the pressure rod 72 away from the hydraulic bin 71 is fixedly connected with a pressure plate 73, the protective door 5 is initially in contact with the opening 4, the pressure plate 73 is located above the base 1, and the protective door 5 and the opening 4 play a protective role to prevent passengers and goods from falling. When the lifting seat 3 moves downward, it will drive the pressure plate 73 to move downward and contact the top of the base 1. The surface of the pressure rod 72 is sleeved with a return spring 74. The other end of the hydraulic chamber 71 is slidably connected to the internal piston of the push rod 75. The top of the push rod 75 is fixedly connected to a gear rod 76. The gear 77 is rotatably connected to the front end of the lifting seat 3. The rack 78 is fixedly connected to the bottom of the protective door 5. The teeth on the gear rod 76 and the rack 78 are meshed with the teeth on the gear 77. The gear rod 76, the rack 78, and the gear 77 are all made of stainless steel. When the gear rod 76 moves, it meshes with the gear 77 to drive the gear 77 to rotate. The rotation of the gear 77 drives the rack 78 to move. The stainless steel gear rod 76, the rack 78, and the gear 77 are not easily damaged by water corrosion.

[0020] When in use, the lifting seat 3 is driven to descend through the lifting device 6. The setting of the slide bar 2 makes the lifting seat 3 more stable when rising or falling. The descent of the lifting seat 3 drives the pressure plate 73 to move downward and contact the top of the base 1. At this time, the pressure plate 73 contacts the top of the base 1 to produce extrusion, causing the pressure rod 72 to move upward and enter the hydraulic chamber 71. The return spring 74 is tightened, and the pressure rod 72 moves upward into the hydraulic chamber 71 and drives the push rod 75 to move right through the hydraulic pressure in the hydraulic chamber 71. The push rod 75 moves right and drives the gear rod 76 to move right. The gear rod 76 moves right and meshes with the gear 77 to drive the gear 77 to rotate counterclockwise. The gear 77 rotates counterclockwise. The rotation drives the rack 78 to move leftward, and the rack 78 moves leftward to drive the protective door 5 to move leftward to open the opening 4 at the front end of the lifting seat 3, so as to facilitate the entry and exit of personnel and goods. At this time, when the lifting seat 3 is driven to rise by the lifting device 6, the pressure plate 73 leaves the base 1, and the return spring 74 rebounds and drives the pressure rod 72 to move downward to restore. At this time, the push rod 75 drives the gear rod 76 to move leftward, and the gear 77 rotates clockwise, the rack 78 and the protective door 5 move to the right, and the opening 4 is blocked and closed by the protective door 5 to play a protective role. The automatic opening or closing of the protective door 5 effectively avoids the situation of forgetting to close the protective door 5.

[0021] For example 2, please refer to Figure 1-4 On the basis of the first embodiment, the warning mechanism 8 includes a bell 81 and a rotating rod 82. The bell 81 is fixedly connected to the top of the protective door 5. The rotating rod 82 is rotatably connected to the top of the protective door 5 by being provided with a torsion spring 83. A striker 84 is fixedly connected to the surface of the rotating rod 82. The striker 84 is made of rubber, and the end of the striker 84 away from the rotating rod 82 is arc-shaped. The striker 84 made of rubber and the arc-shaped end will not cause damage to the bell 81 when it hits the bell 81, but will only cause the bell 81 to vibrate and make a sound. The length of the striker 84 is greater than the distance from the protective door 5 to the bell 81. The surface of the bell 81 is made of stainless steel. The striker 84 will hit the bell 81 when it moves with the protective door 5. The bell 81 made of stainless steel is not easily corroded by rainwater.

[0022] When in use, on the basis of Example 1, when the protective door 5 moves to open or close the opening 4, it will also drive the rotating rod 82 to move. When the rotating rod 82 moves, it drives the impact rod 84 to move and hits the bell 81. The impact rod 84 is made of rubber and has an arc-shaped end that hits the bell 81 without causing damage to the bell 81, but only causes the bell 81 to vibrate and make a sound. Then the rotating rod 82 will rotate and drive the impact rod 84 to deflect and pass over the bell 81. Finally, the torsion spring 83 is tightened and rebounds to drive the rotating rod 82 and the impact rod 84 to restore. When the protective door 5 moves, the bell 81 makes a sound to remind the occupants to be careful not to be pinched by the protective door 5.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
