Abstract
The invention relates to the field of high-grade automobile commercial tables, in particular to an inner column of a lifting column of an automobile commercial table. The inner column comprises a column body, guide blocks and a shifting block, the column body is a hollow tube body, the guide blocks are arranged on the outer wall of the bottom of the column body, the shifting block is arranged on the side face of the top of the column body, the front face of the shifting block is a plane parallel to the radial direction of the column body, the rear face of the shifting block is an arc surface connected with the column body, and a reinforcing rib is arranged in the hollow portion of the shifting portion. The inner column ascends and descends along a set track and cannot cause relative rotation, and the inner elements are protected.
Description
Technical field
The present invention relates to high-grade automobile business table field, relate generally to a kind of automobile business table lifting column inner prop.
Background technology
Along with the development of modern society, commercial car is adopted by people more and more at large, people are also more and more higher to the requirement of business desk in commercial vehicle, the lifting of business desk table is controlled by lifting column, the inside and outside post of existing lifting column is cylindrical shape, and lifting column inside easily relatively rotates and causes internal component damage to affect use.
Summary of the invention
Technical problem to be solved by this invention overcomes the defect existed in above-mentioned prior art, provides a kind of automobile business table lifting column inner prop, and it along the track of setting, can not cause and relatively rotate when being elevated, protection inner member.
The technical solution adopted in the present invention is: a kind of automobile business table lifting column inner prop, comprise cylinder, guide pad, shifting block, described cylinder is the body of inner hollow, described guide pad is arranged on cylinder bottom outer wall, described shifting block is arranged on the top-side of cylinder, be the plane radial parallel with cylinder before shifting block, after be the cambered surface that connects with cylinder, shifting block inner hollow is provided with one reinforcement.
Described guide pad quantity is 3, uniform along cylinder bottom outer wall circumference, and the angle between 3 guide pads is 120 °.
Described cylinder top is provided with a circle boss, boss bottom surface is concordant with shifting block bottom surface, boss upper end cylinder outer wall is provided with four and supports block, four are supported block and distribute along the cylinder outer wall circumference opposing with shifting block, angle to interblock is 60 °, be provided with groove in the middle of the block, parallel with boss face to block bottom surface, end face is domatic under being tilted to.
Be provided with stiffener between described shifting block front upper and cylinder tube wall, stiffener is provided with circular hole.
The invention has the beneficial effects as follows: adopt such scheme, three guide pads bottom cylinder make cylinder along the lifting of setting track, prevent cylinder from relatively rotating damage inner member, the shifting block at cylinder top and support agllutination and close the lifting that lifting column external switch controls lifting column, boss then can the table bracing frame of supporting elevation column top stably.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is top view of the present invention.
Wherein: 1 is cylinder, 2 is guide pad, and 3 is shifting block, and 4 is reinforcement, and 5 is boss, and 6 for supporting block, and 7 is stiffener.
Detailed description of the invention
As Fig. 1, a kind of automobile business table lifting column inner prop, comprise cylinder 1, guide pad 2, shifting block 3, cylinder 1 is the body of inner hollow, cylinder 1 inside is used for arranging air spring, guide pad 2 is arranged on 1 outer wall at the bottom of cylinder, shifting block 3 is arranged on the top-side of cylinder 1, shifting block 3 is the plane radial parallel with cylinder 1 above, cambered surface below for connecting with cylinder 1, shifting block 1 inner hollow is provided with one reinforcement 4, the intensity that reinforcement 4 strengthens shifting block 3 makes it more durable not fragile, guide pad 2 quantity is 3, uniform along cylinder 1 bottom outer wall circumference, angle between 3 guide pads is 120 °, cylinder 1 top is provided with a circle boss 5, boss 5 bottom surface is concordant with shifting block 3 bottom surface, boss 5 is used for support desk board mount, boss 5 upper end cylinder 1 outer wall is provided with four and supports block 6, four support block along 6 with shifting block 3 opposing cylinder 1 outer wall circumference distribute, angle between block 6 is 60 °, groove is provided with in the middle of block 6, parallel with boss face to block 6 bottom surface, end face is domatic under being tilted to, stiffener 7 is provided with between shifting block 3 front upper and cylinder tube wall, stiffener 7 is provided with circular hole, stiffener 7 makes the bonding strength between reinforcement shifting block 3 and cylinder 1, circular hole on stiffener 7 is for connecting other elements, shifting block 3 is connected with external switch mechanism, in conjunction with the lifting controlling lifting column to block 3, guide pad 3 lifting column inner prop uniform bottom cylinder 1 is by the track lifting of setting, and limit relatively rotating of inner prop, protection inner member.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
