A shock absorbing mechanism as described above is characterized in that it also includes an upper shock absorber fixedly connected to the top of the elevator car, and the upper shock absorber includes an upper shock absorber seat fixedly connected to the top of the elevator car plate, an upper guide pin is provided on the upper shock absorber seat plate, an upper bearing sleeve is provided outside the upper guide pin, and an upper and lower coil is arranged inside the upper bearing sleeve. The upper and lower rolling bearings are covered with upper damping rubber rings, the upper guide pins are set in the upper and lower rolling bearings, and the upper and lower rolling bearings The bearing and the upper damping rubber ring are respectively fixed in the upper bearing casing through the upper and lower collar assemblies, and the upper shock absorber fixing connector is fixedly connected to the other end of the upper guide pin. The fixed connection piece of the upper shock absorber is fixedly connected with the vertical beam of the car.

A shock absorbing mechanism as described above is characterized in that the collar assembly includes a collar, and an elastic circlip is arranged outside the collar.

In summary, the present invention has the beneficial effects relative to the prior art as follows:

The present invention has a simple structure, only needs two shock-absorbing fulcrums, which are directly arranged on the lower beam, saves the outer car floor, four horizontal adjustment rods and guide grooves, and saves about 1,000 yuan per unit; the shock absorber is assembled in the factory, The on-site installation is very simple; the service life is long; the shock-absorbing spring is used to effectively prevent the rubber from being susceptible to oil stains and temperature difference corrosion.
