According to the type, it can also be divided into freight elevator cars, elevator cars, passenger elevator cars, etc.
[0003] When the car is working, it is generally controlled to move up and down by a suspension rope. When the car is working, the suspension rope may break, and the car will fall rapidly. In order to prevent the car from falling to the bottom and causing harm to the people inside, a locking structure will be installed on the outside of the car. When the car falls rapidly, the locking structure will open and clamp with the elevator shaft to stop the car. However, when the car stops in an emergency after falling rapidly, the people inside will be subjected to strong inertia, causing harm to the people inside. Therefore, an assembled elevator car is proposed, which can buffer the inertia of the people inside when the car stops in an emergency after falling rapidly. Utility Model Content

Implementation
[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] The utility model provides an assembled elevator car, such as Figure 1-4 As shown, it includes a car bottom 1, a box body 2 and a car top 3. The upper surface of the car bottom 1 and the bottom surface of the car top 3 are fixedly connected to the upper and lower surfaces of the box body 2 respectively.

The front and rear ends of each reduction frame 4 are respectively slidably inserted into the inside of the adjacent frame rods 19. The frame rods 19 increase the stability of the reduction frame 4. At the same time, the frame rods 19 limit the moving path of the reduction frame 4.
[0023] Push rods 13 are provided on the left and right sides of the box body 2 and between the two inclined arc blocks 6. The ends of the two push rods 13 close to each other are fixedly connected to a rotating plate 11. The back of the box body 2 is fixedly connected to a double-headed motor 12. When the box body 2 falls rapidly, the double-headed motor 12 is started, and the rear ends of the two rotating plates 11 are fixedly connected to the two output ends of the double-headed motor 12 respectively. The arc axis of the inclined arc block 6 is coaxially arranged with the axis of the double-headed motor 12. The sides of the two inclined arc blocks 6 close to each other are both spiral inclined surfaces. The push rods 13 are arranged parallel to the axis of the double-headed motor 12. The ends of the two push rods 13 away from each other are rotatably inlaid with balls 18. The balls 18 reduce the wear of the push rods 13 and the inclined arc block 6 when they move relative to each other. The double-headed motor 12 pushes the two push rods 13 to move synchronously through the two rotating plates 11, and the push rods 13 push the reduction frame 4 close to the wall by sliding on the spiral inclined surface of the inclined arc block 6.
[0024] A buffer bottom plate 7 is slidably inserted inside the box body 2, a cylinder 5 is fixedly penetrated on the upper surface of the car bottom 1, a spring 8 is fixedly connected to the inner bottom wall of the cylinder 5, the upper end of the spring 8 is fixedly connected to the bottom surface of the buffer bottom plate 7, and the left and right sides of the buffer bottom plate 7 are slidably inserted with a card plate 9, and the ends of the two card plates 9 that are away from each other slide through the left and right inner walls of the box body 2 respectively. When the card plate 9 is inserted into the side of the buffer bottom plate 7, the buffer bottom plate 7 contacts with the car bottom, so that the buffer bottom plate 7 can stably support the internal personnel during normal operation without shaking, and at the same time reduce The space inside the box 2 is low, which improves the space and comfort of the people inside. After the card plate 9 is separated from the buffer bottom plate 7, the spring 8 pushes the buffer bottom plate 7 to move upward. When the people inside are subjected to inertia, the buffering is completed by pushing the spring 8 to be compressed. The ends of the two card plates 9 that are away from each other are respectively fixedly connected to the two reduction frames 4 located below. The left and right sides of the box 2 are fixedly connected with tension telescopic rods 10. The ends of the two tension telescopic rods 10 that are away from each other are respectively fixedly connected to the sides of the two reduction frames 4 located above that are close to each other.
[0025] A square frame 14 is provided on the inner ring side of the spring 8, and the lower end of the square frame 14 is fixedly passed through the inner bottom wall of the cylinder 5, and a double-sided clamping rod 15 is provided inside the square frame 14, and the upper end of the double-sided clamping rod 15 is fixedly connected to the bottom surface of the buffer bottom plate 7, and a plurality of elastic plates 17 are slidably inserted on the left and right sides of the double-sided clamping rod 15, and the other end of the elastic plate 17 is rotatably connected to the inner wall of the square frame 14, and a baffle 16 is provided below the elastic plate 17, and the baffle 16 is fixedly inserted inside the square frame 14. When the buffer bottom plate 7 moves upward, the double-sided clamping rod 15 drives the elastic plate 17 to rotate upward, so that the elastic plate 17 will not move the double-sided clamping rod 15 upward. When the buffer bottom plate 7 moves downward, the double-sided clamping rod 15 pushes the elastic plate 17 to contact the baffle 16, and the elastic plate 17 applies resistance to the double-sided clamping rod 15 through elastic bending, thereby assisting the spring 8 in buffering the inertia of the buffer bottom plate 7.
[0026] Working principle: when the car is operating normally, the card plate 9 is inserted into one side of the buffer bottom plate 7, so that the spring 8 is in a compressed state, the buffer bottom plate 7 is in contact with the car bottom 1, and there is a larger space in the box body 2 to improve the comfort of use. When the box body 2 falls rapidly, the double-headed motor 12 drives the push rod 13 to move downward on the side of the inclined arc block 6 through the rotating plate 11, and pushes the inclined arc block 6 to drive the reduction frame 4 away from the box body 2, first driving the card plate 9 to disengage from the buffer bottom plate 7, and the spring 8 stretches to push the buffer bottom plate 7 to move upward relative to the car bottom 1, and then the reduction frame 4 contacts the wall to decelerate. The people inside the box body 2 are subjected to the inertia to push the buffer bottom plate 7 to compress the spring 8, and the spring 8 decelerates the inertia of the internal personnel through compression.
