Abstract
The utility model provides a hidden connection structure of a crossed handrail of a rail vehicle, comprising a vertical handrail, a vertical handrail, a connecting rod and a connecting shaft, wherein one end of the connecting rod is provided with a circular tube with one sealed end and a thread hole; the vertical handrail is internally and horizontally provided with a thread sleeve; the connecting rod is horizontally and fixedly arranged on the side face of the vertical handrail through a hexagon-headed bolt and a thread sleeve; the connecting rod and the vertical handrail are sleeved on the connecting shaft; and the connecting rod and the vertical handrail are respectively fixedly connected with the connecting shaft through a countersunk head screw, so that the connecting rod and the vertical handrail are fixedly connected into a whole body. With the adoption of the connecting structure, the handrails are crossly connected through a transition piece and an inner connecting piece and a fastening piece at the connecting part is arranged at the upper part which is not easily observed by a passenger, so that the integrity and the beauty of the handrails and the connecting part are ensured in appearance. A part used at a crossed handrail connecting part is low in cost, is easy to machine and has a short production period; and the previous crossed handrail connection structure is extremely improved in appearance and cost.
Description
Technical field
The utility model relates to the stealthy linkage structure of a kind of rail vehicle intersection handrail, especially goes up the stealthy linkage structure of vertical handrail and vertical arm rest, belongs to packing technique field in the rail vehicle.
Background technique
At present, vertical handrail presss from both sides with adopting Hough being connected of vertical arm rest more on the rail vehicle.This linkage structure is for being connected vertical handrail through bolt between the two halves Hough folder with vertical handrail; Cause the connection slit to reach inequality more greatly easily; Fastening piece exposes and has potential safety hazard simultaneously; Influence attractive in appearancely, increased manufacture cycle, purchase cost, the installation work-hour of product, increased the cost of vehicle.
Summary of the invention
The utility model technical problem to be solved is, overcomes the above-mentioned shortcoming of existing technology, provides a kind of rail vehicle to intersect the stealthy linkage structure of handrail.
In order to solve above technical problem; The stealthy linkage structure of rail vehicle intersection handrail that the utility model provides, comprising: vertical handrail, vertical handrail is characterized in that: also include connecting rod, coupling shaft; Said connecting rod is the pipe of an end confining zone screw; Be horizontally disposed with thread bush in the said vertical handrail, said connecting rod is through the side of being fixed in vertical handrail of hexagon head bolt, thread bush level, and said connecting rod is enclosed within on the coupling shaft with vertical handrail; And said connecting rod is fixed through sunk screw and coupling shaft respectively with vertical handrail, thereby connecting rod and vertical handrail are fixed as one.
Further, be provided with lock washer between the spiral shell head of said hexagon head bolt and the connecting rod end face; Said vertical handrail and sunk screw joint are provided with pad.
Further, sunk screw, pad are arranged at the upper surface of connecting rod, vertical handrail.
The vertical handrail and the connecting rod of the utility model are fastened on the coupling shaft through sunk screw, and connecting rod is fastened on the thread bush on the vertical handrail through hexagon head bolt and lock washer.This linkage structure realizes interconnection through transition piece and interconnect with handrail, and the fastening piece of joint is located at the top that the passenger is not easy to see, from integrity and the aesthetic property that has guaranteed handrail and joint in appearance.Wherein, the cost of parts that the handrail joint adopts of intersecting is low, is prone to processing, and is with short production cycle, intersection handrail linkage structure before having improved greatly on outward appearance and the cost.The sunk screw surface is concordant with the grab bar surface, and transition is smooth, and the oarsman does not conveniently install, and has avoided fastening piece to expose the potential safety hazard of existence.From in appearance, it is little that this new structure connects slit, evenly distributes, and aesthetic property is good.
The erection sequence of the stealthy linkage structure of this intersection handrail is following: vertical handrail is installed earlier, and wherein thread bush is to be installed in advance on the vertical handrail; Connecting rod is installed then; Vertical handrail is installed at last, when vertical handrail is installed, is noted: earlier coupling shaft is placed in vertical handrail, with after vertical handrail and the connecting rod alignment coupling shaft being moved on to the tram, puts pad, fastening screw trip bolt again.
It is thus clear that the stealthy linkage structure of this intersection handrail is in installation, simple when changing, quick.Concerning rail vehicle MANUFACTURER, reduced product component quantity, shortened the manufacture cycle, reduced cost; Concerning rail vehicle operator, reduced the purchase cost of vehicle.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the stealthy linkage structure sectional view of the utility model rail vehicle intersection handrail.
Fig. 2 is the stealthy linkage structure plan view of the utility model rail vehicle intersection handrail.
Embodiment
The stealthy linkage structure of rail vehicle intersection handrail of present embodiment; Like Fig. 1, shown in Figure 2, comprising: vertical handrail 8, vertical handrail 1, it also includes connecting rod 3, coupling shaft 2; Connecting rod 3 is the pipe of an end confining zone screw; Be horizontally disposed with thread bush 4 in the vertical handrail 8, connecting rod 3 is through the side of being fixed in vertical handrail 8 of hexagon head bolt 14, thread bush 4 levels, and connecting rod 3 is enclosed within on the coupling shaft 2 with vertical handrail 1; And connecting rod 3 is fixing with coupling shaft 2 through sunk screw 19 respectively with vertical handrail 1, thereby connecting rod 3 and vertical handrail 1 are fixed as one.
Like Fig. 1, shown in Figure 2, be provided with lock washer 15 between the spiral shell head of hexagon head bolt 14 and connecting rod 3 end faces, vertically handrail 1 is provided with pad 7 with sunk screw 19 joints.
Except that the foregoing description, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
