Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1 to 3, a prevent emergency brake handrail for bus, bus includes roof board 1, and this a prevent emergency brake handrail for bus includes horizontal pole 2 and montant 13, and montant 13 equidistance fixed connection is on horizontal pole 2, and horizontal pole 2 sets up with montant 13 is perpendicular, and montant 13 fixed connection is in the carriage, and a plurality of spouts 8 have been seted up to roof board 1's bottom equidistance, and equal sliding connection has slider 7 in every spout 8. In the preferred embodiment of the present invention, a fixed frame 10 is fixedly connected to the inner bottom end of the sliding block 7 at the sliding chute 8, a roller 9 is mounted on the fixed frame 10, and the roller 9 is in sliding contact with the inner bottom end of the sliding chute 8. The sliding friction between the sliding block 7 and the inner wall of the sliding groove 8 can be changed into rolling friction by arranging the roller 9, and the rolling friction is only one tenth of sliding friction resistance, so that the sliding block 7 is more labor-saving in movement.

The bottom fixed connection of slider 7 has the slide 3 of level setting, and slide 3 can adopt the higher material of quality, and the equidistance is radially cut off on the horizontal pole 2, and common fixedly connected with fixed establishment 5 between two adjacent cross-sections.

In the preferred embodiment of the present invention, the fixing mechanism includes a fixing block 51 and a bolt 53, a slot 52 with two ends communicated with each other is axially formed in the middle of the fixing block 51, the suspension rod 4 is rotatably connected in the slot 52 by a pin, slots 54 are formed in both ends of the fixing block 51, and the cross section of the cross bar 2 extends into the slots 54 and is radially fixed by the bolt 53. The fixing mechanism has the following functions: the cross rod 2 with two cut sides is connected and has the function of being rotationally connected with the suspender 4.

It is further preferred that the rotary connection part of the suspension rod 4 and the fixing mechanism 5 is defined as a fulcrum, and the distance from the top end of the suspension rod 4 to the fulcrum is greater than the distance from the bottom end of the suspension rod 4 to the fulcrum, so that the top of the suspension rod 4 can form a labor-saving lever, and the sliding plate 3 can be driven to move conveniently.

5 internal rotations of fixed establishment are connected with

jib

4, and 3 swing joint of top and the slide of jib 4, swing joint mode specifically as follows: the hanger rod 4 is provided with a limiting groove 12, the limiting groove 12 adopts a structure with arc edges on two sides of a middle rectangle, a cylindrical pin 11 is movably connected in the limiting groove 12, and the cylindrical pin 11 is fixedly connected with the sliding plate 3. The setting of spacing groove 12 plays the effect of tolerance on the one hand for the length of compensation jib 4 prevents the card and dies, and on the other hand plays the effect of "slip moment of change", and cylindric lock 11 to keeping away from fulcrum one side motion alright increase this side moment.

The bottom end of the suspension rod 4 is fixedly connected with a handle 6, in the preferred embodiment of the invention, the handle 6 comprises two connecting blocks 61, a lifting rope 62 and a trapezoidal handle 63, the number of the connecting blocks 61 is two, and the two connecting blocks are respectively and fixedly connected with the bottom end of the suspension rod 4 and the top of the trapezoidal handle 63, and two ends of the lifting rope 62 are respectively and fixedly connected with the two connecting blocks 61. The handle 6 is connected with the suspender 4 through the lifting rope 62, thereby playing the role of flexible connection and buffering, and enabling the handle 6 to be always kept vertically downwards under the action of gravity, and preventing the suspender 4 from directly and rigidly driving the handle 6 to cause discomfort of passengers.

An adult with a high height can avoid emergency braking by holding the cross rod 2, and old, weak, sick, disabled and pregnant women with a relatively low height can avoid emergency braking by the handle 6, the sliding plate 3 is made of a material with a relatively high mass and has relatively high inertia, when the vehicle has emergency braking, the vehicle body suddenly decelerates, the sliding plate 3 continues to move towards one side of the vehicle head under the action of the inertia, the sliding block 7 and the sliding groove 8 can only realize linear sliding, after the sliding plate 3 moves, the sliding plate can overcome the pulling force of the handle 6 pulled by a person at the lower side and further drives the suspender 4 to move, the top of the suspender 4 inclines towards one side close to the vehicle head, and the limiting groove 12 plays a role of 'sliding torque conversion', so the torque required by the upper side of the suspender 4 can continuously and linearly decrease along with the inclination of the suspender 4, and the suspender 4 keeps in an inclined state for a relatively long time, due to the inclination of the suspender 4, the bottom of the suspender 4 can move to one side of the tail of the vehicle, the collision between the old, weak, sick, disabled and pregnant upper body holding the handle 6 and the passengers at the front side or the accessories in the vehicle under the action of inertia is avoided, when sudden braking occurs, the friction between the lower body of the passengers and the vehicle bottom changes the motion state, the upper body tilts backwards under the action of the suspender 4 due to holding the handle 6, the passengers can bear larger force in the horizontal direction due to the fact that the gravity center is close to the back, the stability is higher, and when the vehicle resumes running, the suspender 4 drives the sliding plate 3 to reset under the pulling force of the passengers.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
