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.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1-2, the bus handrail capable of preventing inertial torsion comprises a fixing body 2, a rope belt 7 and a handle 12, wherein the fixing body 2 is connected with the handle 12 through the rope belt 7, the fixing body 2 is installed on a cross rod 1, an opening 10 is formed in the handle 12, a support bar 6 is arranged in the rope belt 7, the support bar 6 comprises an upper filling cavity and a lower filling cavity, non-Newtonian fluid 4 is filled in the upper filling cavity and the lower filling cavity, a plurality of first connecting pieces 5 are symmetrically and fixedly connected to two sides of the upper end of the support bar 6, second connecting pieces 8 are symmetrically and fixedly connected to two sides of the middle of the support bar 6, third connecting pieces 11 are symmetrically and fixedly connected to two sides of the lower end of the support bar 6, a kink is formed below the handle 12, and a;

wherein, the fixed body 2 includes two splint, 1 joint of horizontal pole is between two splint, and two splint are through 3 threaded fixation of a plurality of screws, are provided with the standing groove between two fixed body 2, and the upper end fixed joint of fag end 7 is between two splint, all is connected with fag end 7 through seam line 14 around second connection piece 8 and the first connection piece 5, inserts on two third connection pieces 11 and is equipped with a plurality of axle 9 of inserting, inserts axle 9 and runs through third connection piece 11, fag end 7 and handle 12.

In the invention, when a user uses the device, a passenger holds the notch in the handle 12 with hands, the internal corrugated groove 13 is convenient for the passenger to hold with hands, and simultaneously has an anti-skid effect, when the bus is in a running process and is started and braked, the passenger in the bus can unconsciously topple over due to the inertia effect, and can not tumble as long as the passenger holds the handle firmly, the passenger can correspondingly drag the handle 12 and the rope belt 7 when toppling over, because the rope belt 7 is internally provided with the support strip 6, the support strip 6 is filled with the non-Newtonian fluid 4, and because the support strip 6 is long-shaped, in order to avoid the internal fluid from being uneven up and down, the support strip 6 is divided into the upper filling cavity and the lower filling cavity, so that the upper and lower solutions are uniformly distributed, when the external force is suddenly received, the string 7 as a whole can function during twisting.

The liquid filled in the supporting strips 6 is the non-Newtonian fluid 4, the shearing stress and the shearing stress variability of the fluid are not in a linear relation, by utilizing the characteristics of the shearing thickening body in the fluid, when the force is applied, the self structure of the fluid is changed, the viscosity and the hardness are increased, the shearing force is disproportionately increased, meanwhile, the volume of the fluid is expanded, and finally, the applied pressure is uniformly dispersed to the periphery, when the vehicle normally runs or stops, passengers and the vehicle are in a relatively static state, but when the state of the bus is changed, namely the bus is started from a stop state to a running state, or the bus is braked from the running state, the passengers in the bus can keep the original physical state due to inertia, the body can involuntarily lean backwards or forwards, and even if the passengers hold the surrounding handrail, the body of a person is not a rigid structure, and the problem of toppling can be caused correspondingly, and the traditional mode uses the handrail connected by the completely flexible rope, so that the handrail can not provide good supporting effect actually.

However, when the brake or the start is suddenly performed, the passenger will pull the handle 12 to move forwards or backwards, the movement of the handle 12 will inevitably pull the rope belt 7 to bend or twist, and when the person leans, the handle 12 will bear the inertia impulse of a large part of the body of the person, the force is proportional to the weight of the passenger, the rope belt 7 will also receive the action force, but because the rope belt 7 is provided with the support strip 6, the support strip 6 is filled with the non-newtonian fluid 4, the hardness of the inner support strip 6 is changed when the person suddenly receives the action force, the hardness is larger when the action force is larger, the magnitude of the action force is proportional to the hardness, when the rope belt 7 bends and twists, the non-newtonian fluid 4 inside provides a reverse action force due to the change of the material property, so as to resist the action when the passenger pulls the rope belt 7, when starting or braking occurs, the support bar 6 in the rope belt 7 is transformed into a relatively very hard material structure, one end of the non-Newtonian fluid 4 filled in the cavity on the support bar 6 is installed in the fixed body 2, and the hardness is increased when external force is applied, so that the fixed body 2 and the support bar 6 form a structure similar to a fixed connection, wherein the lower end of the non-Newtonian fluid 4 filled in the cavity under the support bar 6 is fixedly connected with the handle 12 through the inserting shaft 9, so that a structure similar to a fixed connection is formed between the handle 12 and the support bar 6, and then a hard structure is formed among the fixed body 2, the rope belt 7 and the handle 12 when force is applied, the structure supporting passengers is a hard rod-shaped structure, and the passengers can hold the handrail of the hard structure and the feet are in contact with the ground of the carriage, when the passenger is under the inertia action, the problem of random shaking can not occur as long as the passenger grasps the handrail.

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.
