Description

Bus passenger handle

Technical field

The invention belongs to safety appliance field, specifically refer on short distance mass transportation facilities for preventing standee from staggering The bus passenger handle fallen down.

Background technology

The traffic works such as routine bus system vehicle that short-working bus is primarily referred to as in urban area, underground, ground tramcar Tool, owing to the passenger person of standing of this kind of vehicle is more, the most all devices have passenger handle, and they are usually consolidating of bunchiness On the vertical pole of longitudinal direction of car device, clean and tidy for outward appearance takes same height on device height, and actually used In this uniform passenger handle passenger that but has deficiency, mainly height shorter inconvenience very when using, or Can't reach or tilt tiptoe and reach reluctantly to settle health is hung draw very uncomfortable, practicality the most easily makes health unstable, Can not well play protection passenger design function, so in actual life people be sought after one pull height can be because of people And same height can be retracted to novel passenger handle attractive in appearance during the different unmanned use of suitable regulation.

Summary of the invention

The purpose of the present invention is to provide the new technical scheme bus passenger handle of a kind of passenger handle, and it is permissible Eliminate above-mentioned all inconvenience, preferably protect the safety of passenger.

The technical scheme is that and be achieved in that, it comprises vertical pole, latch closure, described latch closure by bearing pin thereon to Under be connected to a link assembly, a V-arrangement shell fragment card is not on the link assembly rivet of bearing pin and left and right sides thereof；Shake hands in a frame-shaped Upper side frame on process one without the step trough of the above-below direction at the bottom of medial launder and a horizontal elongated slot, two of link assembly lower end Connecting rod stretches into two rivets length slightly at step trough and its position, termination and stretches out forwards, backwards in elongated slot；The I-shaped that one top lengthens The pull bar of shape submerges in the step trough under elongated slot, and it enters in Handle frame through step trough below, and its top the most upwards processes Have the symmetrical teeth of row to become ratch, the inclined-plane of the teeth all at right angles teeth of triangle and left and right sides relatively rather than Opposing, the left and right sides returning apparatus under ratch has turriform stage clip, teeth to contact with the rivet in elongated slot.

The invention has the beneficial effects as follows that the height that just can be regulated handle by shirtsleeve operation easily is to adapt to different body High people use, and shake hands and can automatically revert to uniform original state after using.

Accompanying drawing illustrates:

Fig. 1 be the design illustrate handle front view (left and right two figure represents the handle of initial condition and pull-down state respectively, Additionally what is called faces the direction, both sides referring to vehicle).

Fig. 2 is the decomposing schematic representation assembling front each parts.

Fig. 3 is to pull handle first to pull pull bar to move down when regulating its height under preparation to redraw each portion that link assembly lengthens Part operating position relation schematic diagram.

In each figure, 1 is vertical pole, and 2 is latch closure, and 3 is bearing pin, and 4 is V-arrangement shell fragment, and 5 is link assembly, and 6 is pull bar, and 7 for drawing Hands, 8 is ratch, and 9 is turriform stage clip, and 10 is elongated slot, and 11 is step trough.

Detailed description of the invention:

Illustrate the design below in conjunction with the accompanying drawings.

As shown in Figure 1, Figure 2, Figure 3 shows, the technical scheme of the design comprises vertical pole 1, latch closure 2, and latch closure 2 is fixed on vertical pole 1, Latch closure 2 is connected to downwards the link assembly 5 of a parallelogram like, a V-arrangement bullet by the bearing pin 3 that rivet-like thereon is grown slightly Sheet card is not on the link assembly rivet of bearing pin and left and right sides thereof, and the shape of this rivet is also required to grow slightly such as bearing pin 3 certainly So that the most fixing with V-arrangement shell fragment card, the elastic force trend of shell fragment is to strengthen the opening of V-arrangement, i.e. in the situation without other external force Lower link assembly 5 can be in short status because of the resilient force of V-arrangement shell fragment, in the vertical direction when there being the downward tractive of external force Time external force can overcome the elastic force falling shell fragment promote link assembly change shape elongate gradually downward, this shell fragment can be as shown in the figure One, a device can also be according to needs at front and back two sides all devices；At its thickness on the upper side frame of a Back Word shape handle 7 Middle part process a step trough 11 having three grades of ladders from the top down, the middle part of step trough bottom land penetrates downwards handle The upper side frame of 7, is also machined with a horizontal elongated slot 10 in the width range of the top position step trough of this upper side frame, and elongated slot exists Front and back upwardly penetrate through the upper side frame of handle, as shown in the exploded view of the handle 7 of Fig. 2；By two connecting rods of link assembly 5 lower end Stretch out forwards, backwards in elongated slot 10 and rivet, when even in stretching into step trough 11 and by long slightly for two rivets at its lower end position When bar assembly elongates or shortens, these two rivets can be near sliding or away from slip in elongated slot；It is I-shaped that one top lengthens Pull bar 6 also submerges in the step trough 11 under elongated slot 10, and it enters in Handle frame through step trough below, and its top the most upwards adds Work has the symmetrical teeth of row to become ratch 8, the teeth of the teeth on ratch all at right angles triangle and left and right sides Inclined-plane is relative rather than opposing, and teeth rivet with link assembly lower end in elongated slot contacts, and this kind of features of shape of teeth makes It can stop two rivets close to centre in elongated slot reliably, be but more easy to so that two rivets to both sides away from, it addition, by In the position of the lower ora terminalis rivet to be exceeded of connecting rod, in order to allow the teeth on ratch contact preferably handle reliably with rivet Teeth be processed into before and after two rows side by side, leave the roller seating space the most somewhat deepened between two toothrow teeth to accommodate ora terminalis (figure under connecting rod In single display draw), naturally it is also possible to processing teeth higher also to eliminate this problem, the most overall volume is also wanted Strengthen；Left and right sides returning apparatus under the ratch 8 of pull bar 6 has turriform stage clip 9, the lower end of turriform stage clip to be pressed in step trough on the lower Ladder on, when pull bar drop-down compression turriform stage clip, this spring can seldom take vertical blank because of the construction features of its turriform Between, such the design illustrate handle structure just describe, as shown in the handle legend on the left of Fig. 1, when this is not use Initial condition；In specifically used, when be height higher be just to need not when the people of regulation handle height uses that he can be straight Connect and hold the lower frame of handle 7 to keep the safety and stability of self, though as it was previously stated, handle by downward pulling force but pull bar not By the teeth operated on the i.e. ratch 8 of still maintaining the original state, the effect that the rivet of elongated slot inside connecting rod assembly lower end stops to both sides is not changed Becoming, link assembly can be therefore without stretch downward, and whole handle the most also will not change on downward length direction, long Spend stable handle and can give user security and stability；When user is a shorter people needing regulation handle height of height During use he can first tilt tiptoe reach into pull bar 6 in Handle frame following on slightly downwards force pull pull bar, pull bar Pulled downwards turriform stage clip 9 and moved down teeth departing from the most just losing riveting with contacting of rivet in elongated slot by compression ratch 8 The barrier effect of nail, shape as shown in Figure 3, the most this lower pulling force also overcomes the elastic force of V-arrangement shell fragment, in the effect of lower pulling force Two rivets in lower elongated slot can make near slip, link assembly the most therefore stretch downward some, comfortable when reaching user Just can unclamp the lower frame pressing down the finger of pull bar to hold lower section handle again after using height, now pull bar can be because of turriform The effect of stage clip 9 elastic force upwards recovers its initial height, and have left the rivet of its initial position in elongated slot the most again can be with The teeth corresponding with its new position on ratch 8 contact thus secure again position namely secure the height of link assembly Degree, handle the most stable after regulation can give user security and stability equally, such as the handle on right side in Fig. 1；Use Rear handle is without lower pulling force, and under the effect of V-arrangement shell fragment elastic force, two rivets in elongated slot can be forced both sides to the left and right and make remote From slide apart, the bevel feature of teeth is this will not to stop this away from the side, inclined-plane being provided separately the i.e. teeth of facility Rivet to the separate mobile of both sides until the left and right end position of elongated slot (this moving process is the most also to press turriform under ratch is forced The process of stage clip), link assembly retracts to the shortest shape, and whole handle is returned to again the initial condition before it uses, on the left of Fig. 1 Handle diagram shape.It addition, during actual processing and fabricating in order to allow handle the most more flexible can also be at latch closure position Additional a horizontal rotation structure is set.
