[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: an elevator car top fixing installation mechanism, including a box body 1, a bracket 14 is arranged at one end of the box body 1, a support 15 is arranged at one side of the bracket 14, a pull ring 16 is slidably connected to one side of the support 15, a spring member 17 is fixedly welded to one end of the pull ring 16, one end of the spring member 17 is fixedly welded to the support 15, a latch 18 is arranged at one end of the pull ring 16, a slide bar 19 is slidably connected to one side of the bracket 14, and a guardrail 20 is arranged at one end of the slide bar 19. When the maintenance personnel are outside the box body 1 for maintenance operations, they pull the pull ring 16 and deform the spring member 17 to be in a compressed state. A group of jacks are specially provided on the bracket 14, and a plurality of groups of jacks are also provided on the slide bar 19, all of which are used for the latch 18 to pass through. When the pull ring 16 is pulled, the latch 18 is also driven to disengage from the sockets of the bracket 14 and the slide bar 19. Without the locking of the latch 18, the maintenance personnel can adjust the height of the guardrail 20 by lifting and lowering the slide bar 19 according to their own lifting needs. After the adjustment is completed, a group of sockets on the slide bar 19 are aligned with the sockets on the bracket 14, and the force on the pull ring 16 is cancelled. The spring member 17 is rebounded and reset to drive the latch 18 to pass through the bracket 14 and the slide bar 19, and the slide bar 19 is locked. After the adjustment is completed, the maintenance work can be carried out. The guardrail 20 has a protective effect on the maintenance personnel, and it also meets the safety issues when the elevator is performing maintenance work, reduces safety risks, and avoids the occurrence of elevator accidents. It is very practical.

[0023] A door 3 is provided on one side of the box body 1, and a safety sign 4 is provided on one side of the door 3. The safety sign 4 can let the elevator passengers know the safety warning category and emergency rescue measures, etc. The safety sign 4 is affixed to the front and back sides of the door 3, and the position is obvious, so that passengers can clearly understand it and reduce the probability of dangerous events.

[0024] A dustproof plate 12 is rotatably connected to one side of the box body 1, and a snap fastener 21 is provided on one side of the dustproof plate 12. A card slot 13 is provided at one end of the box body 1. The maintenance personnel can reach the top of the box body 1 for maintenance work by opening the dustproof plate 12. When the dustproof plate 12 needs to be closed, it is only necessary to insert the snap fastener 21 into the card slot 13. Because the box body 1 and the snap fastener 21 are both made of metal materials, a strong magnet is provided on the outside of the snap fastener 21, which can be firmly adsorbed in the card slot 13, thereby realizing the closure of the dustproof plate 12. When it needs to be opened, it is also very convenient. A handle is provided on the upper end of the snap fastener 21. The maintenance personnel hold it and apply force to open the dustproof plate 12.

[0025] A filter is provided at one end of the dustproof plate 12, and there are several filter screens. While the filter screen ventilates the air flowing into the box body 1, it also intercepts impurities such as dust to prevent them from falling into the box body 1, thereby keeping the inside of the box body 1 clean and avoiding respiratory infections for passengers.

[0026] A fixed block 6 is provided on one side of the box body 1, and the fixed block 6 is provided with two groups. A motor 7 is provided on one side of one group of fixed blocks 6, and a lead screw 8 is provided at one end of the output shaft of the motor 7. One end of the lead screw 8 is rotatably connected to the other group of fixed blocks 6. A slider 10 is threadedly connected to one side of the lead screw 8, and a fixed rod 9 is slidably connected to one side of the slider 10. One end of the fixed rod 9 is fixedly connected to the fixed block 6. A sound insulation board 11 is provided at one end of the slider 10, and one end of the sound insulation board 11 is slidably connected to the box body 1. Before the maintenance personnel need to open the dustproof plate 12, they need to remove the sound insulation board 11 first. The sound insulation board 11 plays a certain role. As for the sound insulation effect, during the lifting process of the box body 1, the dustproof plate 12 will vibrate and generate some noise due to the influence of wind force, while the sound insulation plate 11 has the effect of reducing noise and will not hinder the ventilation inside the box body 1. The maintenance personnel only need to start the motor 7, and its output shaft drives the lead screw 8 at one end to rotate. The lead screw 8 drives the slider 10 through the thread. The slider 10 is restricted by the fixed rod 9 and slides smoothly. When it moves, it drives the sound insulation plate 11 to move together. At the same time, one end of the sound insulation plate 11 is embedded in the slide groove of the box body 1 and slides. This slide groove provides support for the sound insulation plate 11 to prevent it from falling.

[0027] A protective cover 5 is provided on one side of the box body 1, and the protective cover 5 mainly protects the sliding door assembly and prolongs its service life.

[0028] A single chip microcomputer 2 is arranged on one side of the box body 1. The specific model of the single chip microcomputer 2 disclosed in the present device is Siemens S7-200, which is used to control the motor 7. The single chip microcomputer 2 controls the operation of the motor 7 using a method commonly used in the prior art.
