Description

A kind of trackless trolley car collector bow with spring
Technical field
The utility model relates to public transport technical field, particularly a kind of trackless trolley car collector bow with spring.
Background technology
At present for the trackless trolley car of public conveyance and transportation, due to its have that noise is low, non-pollution discharge, startup are fast etc., and feature is applied by emphasis, collector bow is as the vitals of trackless trolley car, and its design seems particularly important.
Utility model content
Feature and advantage of the present utility model are partly stated in the following description, or can be apparent from this description, or learn by putting into practice the utility model.
For overcoming the problem of prior art, the utility model provides a kind of trackless trolley car collector bow with spring, comprising: underframe, which is provided with actuating device; First lower arm rod, is flexibly connected with this underframe; Second lower arm rod, is flexibly connected with this underframe, and is connected with this actuating device; Upper armed lever, one end is flexibly connected with this second lower arm rod, and the other end is connected with conduction slide plate; Spring, one end is connected with this first lower arm rod, and the other end is connected with this second lower arm rod.
Preferably, the length of this spring elongation is less than 50 centimetres.
By reading specification sheets, those of ordinary skill in the art will understand the characteristic sum content of these technical schemes better.
Accompanying drawing explanation
Below by with reference to accompanying drawing describe the utility model particularly in conjunction with example, advantage of the present utility model and implementation will be more obvious, wherein content shown in accompanying drawing is only for explanation explanation of the present utility model, and do not form restriction of going up in all senses of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of the trackless trolley car collector bow with spring of the utility model embodiment.
Detailed description of the invention
As shown in Figure 1, the utility model provides a kind of trackless trolley car collector bow with spring, comprising: underframe 7, which is provided with actuating device 6; First lower arm rod 1, is flexibly connected with this underframe 7; Second lower arm rod 2, is flexibly connected with underframe 7, and is connected with this actuating device 6; Upper armed lever 3, one end is flexibly connected with the second lower arm rod 2, and the other end is connected with conduction slide plate 5; Spring 4, one end is connected with the first lower arm rod 1, and the other end is connected with the second lower arm rod 2.In the present embodiment, the length of this spring elongation is less than 50 centimetres.The trackless trolley car collector bow with spring that the utility model provides, actuating device 6 is utilized to drive the second lower arm rod 2 to move, second lower arm rod 2 then drives armed lever 3 to move, the first lower arm rod 1 and the second lower arm rod 2 can be made to keep variable distance by spring 4 simultaneously, and the motion of upper armed lever 3 is finely tuned, thus make conduction slide plate 5 can with wire good contact.Visible, the trackless trolley car collector bow structure with spring that the utility model provides is simple, and cost is low.
Above with reference to the accompanying drawings of preferred embodiment of the present utility model, those skilled in the art do not depart from scope of the present utility model and essence, and multiple flexible program can be had to realize the utility model.For example, to illustrate as the part of an embodiment or the feature that describes can be used for another embodiment to obtain another embodiment.These are only the better feasible embodiment of the utility model, not thereby limit to interest field of the present utility model that the equivalence change that all utilization the utility model specification sheetss and accompanying drawing content are done all is contained within interest field of the present utility model.
