Abstract
The utility model relates to a floor spring which is opened for 180 DEG in single direction, which comprises a casing, a pull rod, a shaft center, a spring and a piston. The utility model is characterized in that both sides of the front end of the pull rod are provided with outer bulges on which holes are arranged, a groove and a hole are arranged on the shaft center, a shaft center plug is arranged in the hole and connected with a hole on the pull rod, a roller steel core is arranged on another hole, and the outside of the roller steel core is sheathed with a centrifugal roller. Two sections of relative step break lines are arranged on an outside arc line of the shaft center, the front end of the spring is provided with stop dogs, the stop dog on one side are matched with the step break lines of the outside arc line of the shaft center, and another stop dog is matched with the centrifugal roller. The utility model has the advantages that an opening angle of door leaves can be enlarged to facilitate people to come and go, and the door leaves are hard to impact by external force.
Description
The utility model relates to a kind of floor spring, particularly a kind of floor spring of unidirectional unlatching 180 degree.
The maximum angle of at present general floor spring open and close is 116 degree, and fixed point is 90 degree, because angle is little, door leaf takes up room greatly, comes in and goes out to personnel and causes very big inconvenience, and the angle wicket is also damaged by external force collision easily in addition.
The purpose of this utility model provides the floor spring that unidirectional unlatching 180 degree of a kind of energy make things convenient for personnel to come in and go out.
The technical solution of the utility model is the floor spring of a kind of unidirectional unlatching 180 degree of design, comprise housing, pull bar, the axle center, spring, piston, it is characterized in that: there is evagination the front end both sides of pull bar, porose on the evagination, the groove that one 270 degree are arranged on the axle center, one hole is arranged on the axle center, there is the axle center to tie to connect the evagination hole on the pull bar in the hole, one roller steel core is arranged on another evagination hole, the roller steel core is with a centrifugal roller outward, and two sections relative rank broken strings are arranged on the camber line of outside, axle center, and the front end of spring has block, the block of one side cooperates with the rank broken string of outside, axle center camber line, and the opposite side block cooperates with centrifugal roller.
The utility model has the advantages that can make door leaf increase opening angle makes things convenient for personnel to come in and go out and door leaf is difficult for by external force collision.
Below in conjunction with accompanying drawing the utility model is elaborated,
Accompanying drawing 1 is a schematic perspective view of the present utility model,
Accompanying drawing 2 is an axle center of the present utility model front view,
Accompanying drawing 3 is a door leaf zero degree schematic diagram of the present utility model,
Comprise housing 1 among the figure, pull bar 2, axle center 3, spring 4, piston 5, it is characterized in that: there is evagination 6 the front end both sides of pull bar 2, on the evagination 6 porose 7, the groove 8 that one 270 degree are arranged on the axle center 3, one hole 9 is arranged on the axle center 3, evagination hole 7 on axle center bolt 10 cylinder lever connecting rods 2 is arranged in the hole 9, one roller steel core 11 is arranged on another evagination hole 7, the roller steel core 11 outer centrifugal rollers 12 that are with, two sections relative rank broken strings 13 are arranged on the 3 outside camber lines of axle center, the front end of spring 4 has the block 14 of block 14, one sides to cooperate with the rank broken string 13 of axle center 2 outside camber lines, and opposite side block 14 cooperates with centrifugal roller 12.
When door leaf turns to zero angle, single order broken string 13 is stopped the door leaf location by block 14, this moment is 13 gapped if break in block 14 and rank, then can cooperate with the block 14 of opposite side door leaf is located by centrifugal roller 12, and when door leaf turns to 180 to spend, another rank broken string 13 turns to block 14 that door leaf is located, this moment, spring was compressed, but can door leaf be strained by the door-inhale on the doorframe, door leaf is replied during relieving, when door leaf rotated, pull bar 2 moved with axle center 3, and the 270 degree grooves 8 that have on the axle center 3 guarantee the rotation of pull bar.
