Abstract

The utility model designs a buffer type self-positioning floor spring. When the rotation of a main shaft is controlled, the utility model can play roles of positioning and buffering by that a steel ball in a ball hole on the side face of a machine core enters a corresponding ball socket on the main shaft under the action of the spring pressure. The utility model comprises an outer casing, the spring, the cassette mechanism, the main shaft, and a rocking arm, and is characterized in that the ball hole on the side face of the machine core is at least one; the steel ball, the spring, and a bolt are arranged in the ball hole in sequence; the cylindrical main shaft is sheathed on the machine core; the ball socket on the main shaft of the utility model corresponds to the ball hole on the side face of the machine core.

Description

The self-align floor spring of buffer-type

The utility model belongs to alumium alloy door and window five metals class accessory, is the self-align floor spring of a kind of buffer-type specifically.

The floor spring complex structure that uses, and manifold accessory at present damages easily, after the oil pump wearing and tearing, do not have cushioning effect, impact force was bigger when door was closed, and damaged gate and glass easily, the movement rapid wear does not have positioning action, causes a unlatching malfunctioning.

The purpose of this utility model then is the problem that exists at above-mentioned prior art, the steel ball that has designed in the ball hole, a kind of movement side enters corresponding ball-and-socket on the main shaft under the spring pressure effect, the self-align floor spring of buffer-type of location and buffering effect when playing the control main axis rotation.

The purpose of this utility model can reach by following measure:

The self-align floor spring of a kind of buffer-type, comprise shell, spring, movement, main shaft, rocking arm, it is characterized in that ball hole, movement side at least one, pack into successively in the hole steel ball, spring, bolt, cylindrical spindle is enclosed within on the movement, and the ball-and-socket of its main shaft is corresponding with the ball hole on the movement side.

The purpose of this utility model can also reach by following measure:

Movement is cylinder or square body, and four ball holes on movement four sides are corresponding one by one with four ball-and-sockets on the cylindrical spindle.

Advantage of the present utility model:

The main force part of the self-align floor spring of buffer-type is the friction between main shaft and the steel ball, because main shaft and steel ball all are by quality material production, and through Overheating Treatment, scuff resistance is very high, and is not fragile, durable in use.Work as rotating spindle, when steel ball left the ball-and-socket of main shaft, the opening angle at gate can be selected arbitrarily, did not have impact force when the opening and closing gate.The self-align floor spring of buffer-type also has advantages such as volume is little, simple in structure, and labor and material saving is saved cost, and is economical and practical simultaneously.

Below in conjunction with accompanying drawing the utility model is further described:

With the cylindrical spindle movement main shaft middle part fixing hole 3 of packing into, main shaft lower end 6 and movement main shaft lower fixed hole 2, main shaft middle-end 7 are matched with movement main shaft middle part fixing hole 3, in the ball hole 1 of four sides of movement, put into steel ball, spring successively, the bolt of screwing on, make the moderate pressure of spring action on steel ball, and make that steel ball is corresponding one by one to be entered in the ball-and-socket 10 of main shaft, movement is placed shell, cover cover plate 5 then, make cover central hole 4 be inserted in main shaft upper end 8, in cover plate screw hole 11, be screwed into bolt, rocking arm hole 12 is enclosed within on the main shaft loop bar 9.

Claims

1, the self-align floor spring of a kind of buffer-type, comprise shell, spring, movement, main shaft, rocking arm, it is characterized in that ball hole, movement side at least one, pack into successively in the hole steel ball, spring, bolt, cylindrical spindle is enclosed within on the movement, and the ball-and-socket of its main shaft is corresponding with the ball hole on the movement side.

2, the self-align floor spring of buffer-type according to claim 1 is characterized in that movement is cylinder or square body, and four ball holes on movement four sides are corresponding one by one with four ball-and-sockets on the cylindrical spindle.
