Abstract
The utility model discloses a chair table which is provided with an over loading protecting function; and the chair table includes a table plate which is articulated with a backrest of the chair; a spring strut and a pressure spring which is arranged in the spring strut are vertically arranged on the backrest of the seat; rolling balls are arranged at the bottom end of the pressure spring; warping plates are respectively arranged at both sides of the table plate, and one end of the warping plate is extended under the rolling balls from the sidewall of the spring strut. The chair table has the advantages that when the bearing weight of the table is over the designed weight, the end parts of the warping plate at the both sides of the table can press the rolling balls to pass through a limit point, so as to lead the table plate to be fallen automatically and not damage the table plate; the table can be reset by exerting the opposite force, and the over loading resetting process is simple and rapid.
Description
Technical field
The utility model relates to automobile-used or aviation seat dining table, especially relates to the seat dining table with overload protection function.
Background technology
Automobile-used or aviation at present mostly is vaulting pole formula structure with the seat dining table, by vaulting pole the dining table plate on the seat back is propped up during use.The existing deficiency of seat dining table of said structure does not show as: when the load that the dining table plate after strutting is born surpasses design value, the dining table plate will be damaged and can't recover, and can only change, and not only lose time but also improved use cost.
The utility model content
The utility model purpose is to provide a kind of seat dining table with overload protection function of simple and direct practicality.
For achieving the above object, the utility model can be taked following technical proposals:
Seat dining table with overload protection function described in the utility model, it comprises the dining table plate that is articulated on the back of seat; On described back of seat, be vertically installed with spring strut and the pressure spring that places in it, be provided with ball in the bottom of described pressure spring; Being provided with one on the dual-side of described dining table plate respectively has seesaw, and an end of described seesaw extends to described ball below from the spring strut sidewall.
The seesaw upper surface that extends to described ball below is the cancave cambered surface structure.
The utility model advantage just is that when the dining table plate bears above design weight the seesaw end compression steel ball that is arranged on dining table plate both sides is crossed limit point, and the dining table plate comes off automatically and is unlikely to damage; By the dining table plate is applied the recovery that opposite force can be finished dining table, overload rejuvenation is simple to operation.
