Abstract

The utility model relates to a floor spring which comprises a casing, a piston, a draw rod, a spring, a rotary shaft, a cam, an upper and a lower pull plates, a positioning roller, and a rotary shaft groove. The utility model is characterized in that a lower cam having a coaxial offset angle is arranged below the cam arranged below the rotary shaft, and a positioning opening is arranged on the lower cam. An inverted T-shaped roller which is matched with the lower cam is arranged between the upper and the lower pull plates. The utility model has the advantages of multi-angle positioning and horizontal open of 180 DEG. The floor spring is convenient for the unblocking of the road.

Description

A kind of novel floor spring
The utility model relates to a kind of floor spring, particularly a kind of novel floor spring.
The maximum angle that present spring usually can be opened door is that door is unfavorable for The coast is clear for substantially vertically opening about 116 degree when the personnel of being used in pass in and out more occasion, and damages the part of floor spring easily under external force.
The purpose of this utility model provides a kind of novel floor spring of energy 180 degree horizontally openables.
The technical solution of the utility model is a kind of novel floor spring of design, comprise housing, piston, pull bar, spring, turning cylinder, cam, go up lower pulling plate, positioning roller, rotary axis groove, it is characterized in that: the following cam that a coaxial drift angle is arranged under the cam under the turning cylinder, on the following cam positioning port is arranged, the inverted T shape roller that cooperates with following cam is arranged between last lower pulling plate.
The utility model has the advantages that and multi-angle to locate and energy 180 degree horizontally openables, be beneficial to The coast is clear.
Below in conjunction with accompanying drawing the utility model is elaborated,
Accompanying drawing 1 is a structural front view of the present utility model,
Accompanying drawing 2 is a structure vertical view of the present utility model,
Comprise housing 1 among the figure, piston 2, pull bar 3, spring 4, turning cylinder 5, cam 6, last lower pulling plate 7,8, positioning roller 9, rotary axis groove 10, it is characterized in that: the cam under the turning cylinder 5 has the following cam 11 of a coaxial drift angle for 6 times, on the following cam 11 positioning port 12 is arranged, last lower pulling plate 7,8 have the T type roller 13 that cooperates with following cam 11, during use, because following cam 11 and cam 6 coaxial drift angles, when cam 6 forwards T type roller 13 to, inverted T shape roller 13 is not to cam 6 location, and rotate positioning port 12 and inverted T shape roller 13 location on the cam 11 at present again, this moment, the opening angle of door was 160 degree, and when being rotated further, the wheel point of cam 6 is stuck in 9 of two positioning rollers, and this moment, the opening angle of door was 180 degree.And when opening smaller angle, the positioning port 12 of cam 6 and following cam 11 can be located with positioning roller 9, inverted T shape roller 13 one by one.
