Abstract

The present invention provides an armrest matched with backrests of driver's chairs of locomotives and vehicles, which comprises an armrest body, a supporting shaft arranged on the tail part of the armrest body, a limiting element of which one end is arranged on the supporting shaft, a supporting shaft fixing element provided with an installing hole, and a thrust nut arranged on the armrest body in the position corresponding to the limiting body, wherein the supporting shaft conducts corresponding rotation with the armrest body; the supporting shaft fixing element is arranged on the supporting shaft at the end extending out of the armrest body. The tail end of a push rod arranged in the armrest body spirally passes through the thrust nut and is in contact with the limiting element, and the front end of the armrest body is provided with a rotary handle. The adjustment of the inclined angle and the elevation angle of the armrest of the present invention is convenient, and the rigidity of the whole body is reinforced.

Description

The vehicle drivers armrest

Technical field:

The present invention is relevant with handrail, and is relevant with the handrail of vehicle drivers back of seat cooperation especially.

Background technology:

The regulative mode of at present domestic and international some producer's armrest leaning angle, the one, regulating handle is in the bottom of handrail tail end; The 2nd, regulating handle and set screw are solidified as a whole; The 3rd, if when need regulating handrail reclining angle or the people leaves seat, or the people is in very awkward posture on the seat and regulates; The 4th, when regulating the handrail elevation angle, need handrail is dug, make it make handrail perpendicular to the ground substantially, can regulate, it is very inconvenient to regulate handrail reclining angle, and the handrail integral rigidity is relatively poor, easy fracture.

Summary of the invention:

The present invention seeks in order to overcome above deficiency, the vehicle drivers armrest that a kind of handrail reclining angle is easy to adjust, rigidity is strengthened greatly is provided.

The object of the present invention is achieved like this:

Vehicle drivers armrest of the present invention comprises armrest body, be loaded on the armrest body afterbody and with the counterrotating pivot shaft of body, one end is fixed in the locating part on the pivot shaft, pivot shaft stretches out the pivot shaft connecting element that the band mounting hole is housed on the end of armrest body, stationkeeping with respect to locating part on the armrest body has Thrust nut, the push rod tail end screw thread that is arranged in armrest body passes that Thrust nut contacts with locating part and front end is equipped with rotary handle, and handrail can rotate along pivot shaft.

Above-mentioned locating part is a stop screw.

End section is at least square before the above-mentioned push rod, and the hole that is at least square that cooperates with the push rod front end is arranged on the rotary handle.

Above-mentioned handrail is by skeleton, and the covering that is tightly packed on the skeleton is formed the intensity height.

Above-mentioned skeleton is hermetically sealed box like structure, and the engineering plastics that covering adopts injection pressure to be at least 9Mpa are made.

Above-mentioned handrail front end has the groove that cooperates with handle, with respect to handle rear end face position preceding inserts is housed at the recess outlet place, and armrest rear end is equipped with inserts behind the arc, and is not only attractive in appearance but also be convenient to location to rotary handle and handrail push rod.

Above-mentioned locating part axial line is vertical or approximately perpendicular to the pivot shaft axial line.

By screw and pivot shaft connecting element with handrail mounted in pairs of the present invention on the left and right side of vehicle seat back, the driver is seated on the seat naturally, the right hand (or left hand) level is put on the handrail on the plane, thumb is put in plane on the handrail naturally, the curved slightly handrail turning handle of holding of all the other four fingers points to upper right turning handle with four; Rotation along with handle, driving push rod simultaneously rotates, push rod also rotates in the Thrust nut of afterbody simultaneously, because Thrust nut is motionless, so the length of push rod tail end is promptly elongated gradually at this moment, under the restriction of locating part, it is big that gradual change is contended in the handrail reclining, be that the handrail front end is raised gradually, thereby reach the purpose that handrail reclining angle is regulated, otherwise then handrail reclining degree diminishes.

The present invention adopts rotary handle to regulate handrail reclining angle, regulate very convenient, and good looking appearance, integral rigidity is strengthened greatly.

Description of drawings:

Fig. 1 is a structural representation of the present invention.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the upward view of Fig. 1.

The specific embodiment:

Referring to Fig. 1～Fig. 3, armrest body is by the steel frame 2 of the hermetically sealed box like structure that can carry the plastic pressure of 9Mpa and to be coated on injection pressure on the steel frame be that the high pressure engineering plastics covering 3 of 9Mpa is formed.The armrest body front bottom end has rotary handle that groove 4 is installed.Pivot shaft 5 is contained in the armrest body afterbody and can rotates relatively with armrest body.Pivot shaft 5 stretches out the pivot shaft connecting element 6 that is fixed with band mounting hole pivot shaft on the end of armrest body.Stop screw 7 axial line L ₁Vertically (but also near normal) is in pivot shaft 5 axial line L ₂And screw thread is fixed on the pivot shaft.Be fixed with Thrust nut 8 at the armrest body tail end with respect to the stop screw extension, the tailing screw flight that is contained in the push rod 9 on the armrest body passes Thrust nut and contacts with stop screw.The cross sectional shape of push rod is that the cross sectional shape that orthohexagonal head stretches into the rotary handle 10 in the groove that is loaded on the armrest body front portion is that orthohexagonal Kong Zhongyu rotary handle cooperates.Inserts 11 before being equipped with on the position of armrest body front end groove with respect to the rotary handle aft end face, inserts 12 after the armrest body afterbody is embedded with arc.Handrail reclining angle setting range is bigger, regulates with back of seat reclining angle to cooperate very much.

Install when of the present invention, handrail of the present invention is installed on the vehicle seat back left and right side by mounting screw 13.

The foregoing description is that foregoing of the present invention is further described, but this should be interpreted as that the protection domain of the above-mentioned theme of the present invention only limits to the foregoing description.All technology that realizes based on foregoing all belong to scope of the present invention.
