Description
Technical field
The utility model relates to one and steps on car device, particularly the stowable pull access step of a kind of handrail.
Background technology
In some box refitted cars and shelter vehicle, its chassis is relatively high, staff could need to come in and go out compartment or shelter up and down by access step, CN203129938U discloses a kind of pull and folds access step, by guide rail, upper ladder, lower ladder and pedal composition, by fixed pin holes by upper ladder, lower ladder folds in guide rail, and pedal is rotated to and upper ladder, the angle that lower ladder is parallel, thick less than 60mm after access step folding storage, larger saves installing space, use parallel-crank mechanism dexterously, achieve rapidly, launch neatly and collect, but do not configure ascending stair handrail in the pull access step in this utility model patent, make safety during ascending stair not high.
Summary of the invention
The purpose of this utility model be overcome prior art above-mentioned deficiency and provide a kind of handrail stowable pull access step, it provide armrest system, improve safety during ascending stair, and handrail can be realized can collect fast and launch.
The technical solution of the utility model is: the stowable pull access step of a kind of handrail, comprise handrail, ladder body, guide rail, pedal, described guide rail is in " U " shape, guide rail bilateral symmetry is provided with kidney slot, one end of guide rail and terraced body is by the first pinned connection, described terraced body is by a left side, the cross bar composition of right two groups of columns and connection column, it is inner that described pedal is positioned at terraced body, and with column by the second pinned connection, described handrail is positioned at the left and right sides of terraced body, handrail comprises two pull bars and a bar, described pull bar is connected by hinged-support with bar, pull bar by the 3rd bearing pin respectively with the left side of terraced body, right column connects, the link of pull bar and terraced body is equipped with the screw hole running through terraced body and pull bar.
The further technical scheme of the utility model is: the column of described pull bar, bar and terraced body can form parallelogram sturcutre, and the column of terraced body can form oblique tetragonal body structure.
Further, described pull bar is rhs-structure, and bar is round steel structure.
Further, hinged-support standing groove is provided with in described bar.
Further, described screw hole is milled screw hole.
Further, described pedal is provided with anti-skidding projection or anti-slip tank.
The utility model compared with prior art has following features: the handrail that the utility model provides stowable pull access step provides can collect extensible handrail fast, thing was had to hold up when both ensure that ascending stair, improve safety during ascending stair, additionally do not increase placement space again, and structure is simple, easy to operate.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in drawings: the stowable pull access step of a kind of handrail, comprise handrail 5, ladder body 1, guide rail 13, pedal 4, guide rail 12 is in " U " shape, guide rail 13 bilateral symmetry is provided with kidney slot 13-1, guide rail 13 is connected by the first bearing pin 12 with one end of terraced body 1, ladder body 1 is by a left side, the cross bar 2 of right two groups of columns 3 and connection column 3 forms, it is inner that pedal 4 is positioned at terraced body 1, and be connected by the second bearing pin 8 with column 3, handrail 5 is positioned at the left and right sides of terraced body 1, handrail 5 comprises two pull bars 6 and a bar 7, pull bar 6 is connected by hinged-support 9 with bar 7, pull bar by the 3rd bearing pin 10 respectively with the left side of terraced body 1, right column 3 connects, pull bar 6 and the link of terraced body 1 are equipped with the screw hole 11 running through terraced body 1 and pull bar 6.
Access step in use, pull bar 6, the column 3 of bar 7 and terraced body 1 can form parallelogram sturcutre, the column 3 of ladder body 1 can form oblique tetragonal body structure, ensure that the pull bar 6 of handrail 5 has four points of connection with the column 3 of terraced body 1, effectively can limit the degree of freedom of handrail 5, handrail 5 is made to be in stable state, can not double swerve, pull bar 6 is rhs-structure, make pull bar 6 better with column 3 degree of laminating of terraced body 1, bar 7 is round steel structure, the comfortableness of grasping can be increased, hinged-support standing groove is provided with in bar 7, hinged-support 9 can be hidden in when access step is in collecting state in bar 7, do not take up space.
Screw hole 11 is milled screw hole, can direct hand by milled screw tightening screw hole 11, simple and convenient, time saving and energy saving.
Pedal 4 is provided with anti-skidding protruding 4-1, increases the frictional force of pedal 4 and ascending stair personnel foot, safer when making ascending stair.
Operating principle of the present utility model and using method are: pull access step in use, first terraced body 1 is pulled out from the kidney slot 13-1 guide rail 13 by the first bearing pin 12, and four columns 3 of terraced body 1 are launched into oblique tetragonal body structure completely, by the second bearing pin 8, pedal 4 is adjusted to parallel to the ground again, now terraced body 1 is 60 degree with the angle on ground, reduce the length of terraced body 1 while comfortableness when ensure that the upper and lower access step of ascending stair personnel and safety as far as possible, finally by the 3rd bearing pin 10, the pull bar 6 in handrail 5 is pulled out, until stop when making the screw hole 11 on pull bar 6 overlap completely with the screw hole 11 on terraced body 1, and use milled screw to be fixed on by pull bar 6 on terraced body 1, now hinged-support 9 pulls out from pull bar 6, make bar 7 parallel with terraced body 1, now ascending stair personnel can hand steered bar 7, access step is climbed up along pedal 4, handrail 5 and terraced body 1 when collecting, then are stowed in the kidney slot 13-1 of guide rail 13 by hinged-support 9, the 3rd bearing pin 10, second bearing pin 8, first bearing pin 12 along backward when using by pull access step successively.
