A door pump assembly for opening and closing doors of buses

Abstract

The invention discloses a driving pump assembly for an opening-closing door of a bus. The driving pump assembly comprises attic bases, a first damping disc, a pump bin, blocking and connecting rods, a clamping disc, a second damping disc, an adjusting disc, a movable extension rod, a penetrating connection bolt, an upper installation plate, buffer spring coils, a lower baffle, an inserting groove, a clamping bolt, a rotary column, a sliding groove, a sliding rod and a locking ring. The driving pump assembly has the beneficial effects that the front attic base and the rear attic base of the driving pump assembly are both welded and attached to each other through the first damping disc and the second damping disc; by the adoption of the multiple buffer spring coils in the damping discs, on one hand, vibration of the driving pump assembly in the bus can be reduced, and using stability is guaranteed; and on the other hand, frictional losses of the driving pump assembly and all the components of the bus are reduced, and the service life of the driving pump assembly is prolonged. When the driving pump assembly is installed on the bus, an inserting plate of the bus is inserted into the inserting groove of the clamping disc and screwed and fixed through the clamping bolt, and the driving pump assembly is fixed more stably and firmly; and the driving pump assembly is convenient to operate, and all the components are connected flexibly.

Description

technical field [0001] The invention relates to a door pump assembly, in particular to a door pump assembly for opening and closing doors of buses, belonging to the technical field of bus door pump applications. Background technique [0002] With the rapid development of people's living standards, buses are used more and more widely in daily life. There are many kinds of buses with different appearances. Buses refer to following fixed routes on urban roads, with or without fixed shift time, carrying For motor vehicles traveling by passengers, the door pump assembly is indispensable when the bus is used. The door pump assembly is a very important part of the bus. Its main function is to provide power for the bus door to open and close, so that it can Quick opening and closing, convenient for pedestrians to pass. [0003] As a very important part of the bus, the existing door pump assembly has a large friction loss with the bus parts, insufficient stability and reliability, p...

AI Technical Summary

Problems solved by technology

[0003] As a very important part of the bus, the existing door pump assembly has a large friction loss with the bus parts, is not stable enough to be placed, has poor stability, and has a low service life. The length of the movable link connected to the door part is fixed. , not flexible adjustment, poor connection accuracy, and insufficient adaptability. Therefore, in view of the above problems, a door pump assembly for opening and closing doors of buses is proposed.
