In some extreme cases, the car body may be in danger of falling rapidly. When the car body rapidly falls to the bottom of the hoistway, due to the lack of a shock absorbing mechanism at the bottom of the car that can achieve a buffering effect, the personnel in the car will Due to the huge impact force, it will be injured to varying degrees, and the resulting falling force cannot be dispersed in time, which may lead to death in severe cases.

Utility model content

Aiming at the deficiencies of the prior art, the utility model provides a buffer device for a villa elevator that can buffer when the car is dropped.

In order to achieve the above purpose, the utility model provides the following technical solutions: a buffer device for a villa elevator, comprising a bottom plate, a fixed frame is fixed on the upper side of the bottom plate, and a plurality of circumferences around the center line of the bottom plate are fixed on the outer wall of the fixed frame. The fixed rods are evenly distributed. The fixed rod is provided with a chute that communicates with the inner wall of the fixed frame. A first buffer spring is arranged between the bottom surfaces, the other end of the sliding rod is hinged with a buffer rod, a first buffer plate is arranged above the bottom plate, and one end of each of the buffer rods away from the sliding rod is connected to the first buffer rod. Plate hinged.

By adopting the above technical solution, when the car falls on the first buffer plate and gives pressure to the first buffer plate, the first buffer plate moves downward under the pressure, and the buffer rod drives the sliding rod to move into the chute, and the first buffer spring It is compressed by the force of the sliding rod, so as to achieve the function of buffering; because the first buffer spring is arranged in the chute, it can avoid the failure of the first buffer spring caused by the fall of external substances into the inside of the first buffer spring.

Further, the upper side of the bottom plate is also fixed with a fixing column, the upper side of the fixing column is provided with an installation slot with an upward opening, and a support rod is inserted into the installation slot, and the support rod extends into the installation groove. A second buffer spring is arranged between one end and the bottom surface of the installation groove, and one end of the support rod away from the second buffer spring extends out of the buffer plate.

By adopting the above technical solution, when the car falls, it first contacts the support rod, and the support rod moves downward to squeeze the second buffer spring, first buffering a part of the pressure of the car, and the car continues to move downward to contact the first buffer spring. A buffer plate is provided, and the car drives the first buffer plate to move downward. At this time, the first buffer spring and the second buffer spring jointly play a buffering effect on the car, and the buffering effect is good.

Further, a second buffer plate is fixed at one end of the support rod extending out of the buffer plate.

By adopting the above technical solution, the second buffer plate can increase the contact area between the support rod and the car, so that the car is more stable when it falls.

Further, a plurality of reinforcing ribs are arranged between the fixed column and the bottom plate, and the reinforcing ribs are evenly distributed around the axis and circumference of the fixed column.

By adopting the above technical solution, the reinforcing rib can increase the connection strength between the fixed column and the bottom plate.

Further, the upper side of the sliding rod is provided with a positioning groove extending along the length of the sliding rod, the bottom surface of the positioning groove is provided with a number of positioning steps arranged in sequence along the length of the positioning groove, and the height of the positioning steps is determined from the fixing frame. The center increases in sequence toward the outside of the fixing frame, and the fixing rod is provided with a positioning rod with one end extending into the positioning groove.

By adopting the above technical solution, when the first buffer plate is pressed to move downward, the sliding rod is driven to move into the chute. At this time, the lower end of the positioning rod moves to the positioning step with a lower height due to gravity. When it falls to the lowest point, the lower end of the positioning rod moves to the positioning step with the lowest height, and then the sliding rod is moved out of the chute by the rebound force of the first buffer spring, and the lowest positioning step can restrict the sliding rod from moving outward. distance, so as to prevent the car from bouncing upwards due to the rebound force of the first buffer spring and causing discomfort to the personnel in the car.

Further, a first elastic layer is provided above the first buffer plate.

Further, the upper end of the fixing column is provided with a second elastic layer.

To sum up, the beneficial effects of the present utility model are as follows: 1. When the car falls, it first contacts the second buffer plate, the second buffer plate is forced to move downward, and the second buffer spring is squeezed by the support rod, and the second buffer plate is forced to move downward. The buffer spring plays a buffering role first, and the car continues to move downward until the second buffer plate contacts the first buffer plate. The car drives the second buffer plate and the first buffer plate to move downward, and the second buffer plate is driven by the buffer rod. The sliding rod moves into the chute, and the first buffer spring is compressed by the force of the sliding rod. At this time, the first buffer spring and the second buffer spring together play a buffering effect on the car, and the buffering effect is better; 2. The first buffer spring The buffer spring is arranged in the chute, so as to prevent external substances from falling into the inside of the first buffer spring and causing the failure of the first buffer spring.
