[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-11 This embodiment provides an elevator ceiling ventilation structure, comprising an elevator body 1. The body 1 is similar to the elevator car disclosed in Patent Publication No. CN113272237A. To allow air to flow between the interior and exterior of the body 1, a roof 2 is fixedly connected to the upper end of the body 1, with ventilation holes formed at the upper end of the roof 2. To increase the efficiency of air flow between the interior and exterior of the body 1, a fan 3 is fixedly installed within the ventilation holes of the roof 2. The fan 3 is a low-pressure fan of model DFBZ-I-4. The fan 3 blows air into the interior of the body 1, and the air is discharged through the elevator door, thereby increasing the efficiency of air flow between the interior and exterior of the body 1.

[0031] In order to prevent infants, pregnant women, patients and other people who need to avoid the wind from the wind blowing out of the fan 3 from contacting the people riding the elevator, an adjustment mechanism 4 for adjusting the wind direction is provided inside the roof 2.

[0032] Specifically, the regulating mechanism 4 includes an air guide plate 41 and an regulating frame 42, wherein the air guide plate 41 is provided in a plurality, such as Figure 3 As shown, multiple wind guide plates 41 are evenly arranged in a straight line, and rotating rods 412 are fixedly connected on both sides of the wind guide plates 41. The rotating rods 412 are rotatably inserted into the inside of the roof 2, that is, the rotating rods 412 enable multiple wind guide plates 41 to be rotatably installed in the roof 2. By rotating and adjusting the angle of the wind guide plates 41, the wind direction of the fan 3 can be changed to prevent the wind from blowing towards the elevator passengers who need wind protection.

[0033] There are four adjustment racks 42, wherein two adjustment racks 42 are arranged as a group of adjustment members. The two adjustment racks 42 of the same group of adjustment members are distributed up and down. The two groups of adjustment members are respectively located on both sides of the air guide plate 41. Both ends of the air guide plate 41 are fixedly connected to two adjustment rods 411. Figure 3 As shown, the adjustment frame 42 has multiple sliding slots. Two adjustment rods 411 located at the same end of the air deflector 41 are slidably mounted within the two sliding slots of the same adjustment frame 42. The adjustment frame 42 is controlled to slide horizontally within the roof 2. At this time, the adjustment rods 411 slide up and down within the sliding slots of the adjustment frame 42. The inner sidewalls of the sliding slots exert a lateral force on the adjustment rods 411, thereby driving the air deflector 41 to rotate.

[0034] When the wind deflector 41 needs to rotate, the two adjustment racks 42 of the same set of adjustment members need to slide in opposite directions. In order to synchronously control the movement of the same set of adjustment racks 42, a control mechanism 5 is provided in the roof 2. Figure 3 As shown, the control mechanism 5 includes a rack 51 and a control gear 52. The rack 51 is fixedly connected to one end of the adjustment frame 42. Two control gears 52 are provided, and the two control gears 52 are rotatably mounted inside the roof 2. The control gear 52 is located between the racks 51 of the two adjustment frames 42 in the same group, and the control gear 52 and the two racks 51 are meshed with each other. Rotating the control gear 52 drives the two racks 51 to move horizontally in opposite directions, that is, drives the two adjustment frames 42 in the same group to slide horizontally in opposite directions and synchronously.

[0035] In order to synchronize the adjustment frames 42 on both sides of the air guide plate 41 and make the air guide plate 41 rotate stably, a connecting rod 521 is fixedly connected between the two control gears 52. By rotating the connecting rod 521 to synchronize the rotation of the two control gears 52, the angle of the air guide plate 41 can be rotated in coordination with the adjustment mechanism 4 and the control mechanism 5. When adjusting the angle of the air guide plate 41, the connecting rod 521 needs to be rotated, but the connecting rod 521 is located inside the roof 2. Even if a slot is provided so that people can access the connecting rod 521, the height of the roof 2 still prevents most people from accessing the connecting rod 521. In order to manually control the rotation of the connecting rod 521, a driven wheel 55 is fixedly sleeved on the outer wall of the connecting rod 521. Among them, a driving wheel 54 is rotatably installed on the inner wall of the main body 1, and the driving wheel 54 and the driven wheel 55 are located in the same vertical plane. A transmission belt 56 is installed through the interior of the main body 1 and the roof 2, as shown in FIG. Figure 8 and Figure 10 As shown, the two ends of the transmission belt 56 are respectively connected to the outer side walls of the driving wheel 54 and the driven wheel 55, as shown in FIG. Figure 9 As shown, two guide pulleys 561 are installed for rotation within the roof 2. A transmission belt 56 passes around these two guide pulleys 561, forming an L-shaped structure. The transmission belt 56 can be configured as a toothed belt or a chain. When the transmission belt 56 is configured as a toothed belt, both the driving pulley 54 and the driven pulley 55 are configured as pulleys. When the transmission belt 56 is configured as a chain, both the driving pulley 54 and the driven pulley 55 are configured as gears. When the driving pulley 54 rotates, the transmission belt 56 drives the driven pulley 55 to rotate, which in turn drives the connecting rod 521.

[0036] The inner side wall of the main body 1 is provided with a rotating hole, in which a control disk 57 is rotatably mounted. The end surface of the control disk 57 facing the driving wheel 54 is fixedly connected to the second bevel gear 571, and one end of the driving wheel 54 is fixedly connected to the first bevel gear 541. Figure 10 As shown, the first helical gear 541 and the second helical gear 571 are meshed with each other. Figure 11 As shown, a receiving groove is provided on the end surface of the control disk 57 away from the second bevel gear 571, and a rocker 572 is rotatably installed in the receiving groove, that is, one end of the rocker 572 is rotatably connected to the inner end of the receiving groove. By rotating the rocker 572, the rocker 572 and the control disk 57 are vertically distributed. The control disk 57 can be rotated by holding the rocker 572, and the second bevel gear 571 rotates synchronously with the rotation of the control disk 57, and the driving wheel 54 can be driven to rotate through the first bevel gear 541.

[0037] When the rocker 572 rotates and is perpendicular to the control panel 57, the rocker 572 protrudes from the inner side wall of the main body 1. If the passengers hit the protruding rocker 572, it will cause serious injuries. In order to reset the rocker 572 after the control panel 57 is rotated, a spring bar 573 is fixed in the storage slot of the control panel 57. Figure 11As shown, the spring bar 573 is configured as a U-shaped metal bar, one end of the spring bar 573 is fixedly connected to the storage slot, and the other end of the spring bar 573 is fixedly connected to the outer wall of the rocker 572. The contraction elastic force of the spring bar 573 applies a pulling force to the rocker 572 in the direction of the storage slot, and then after the elevator passenger releases the rocker 572, the rocker 572 is reset by the elastic force of the spring bar 573.

[0038] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
