Abstract

The utility model discloses multi stage limit door spindle which comprises a door frame and a movable door spindle. The utility model is characterized in that: the lower part of the movable door spindle is provided with a movable connector that can rotate along the door spindle and whose lower part is provided with a horizontal lower adjoining plane which is provided with a pit. The connector seat that is fixedly connected with the door frame is provided with a localizer that is installed right below the movable door spindle. The localizer is provided with a horizontal adjoining plane that attaches the lower adjoining plane of the movable connector closely. The upper adjoining plane is provided with a lower pit, the butted upper and lower pits are provided with balls. When push the door, the movable connector rotates relative to the localizer, the balls will slip out from the pits to block the adjoining plane to elevate the movable door. When the movable connector rotates to certain to a preset angle, the balls will slip back into the pits to block the rotation. When the torque force is smaller than the resistance, the balls will maintain in the pits to perform the functions of stopping and limiting so as the realize multi stage opening and closing of the door.

Description

The spacing door-hinge structure of multisection type

[technical field]

The utility model belongs to a kind of door-hinge structure.

[background technology]

At present; generally the vertical hinged door of Shi Yonging generally can divide two classes; first band is the rotary shaft vertical hinged door up and down; it two is to adopt the hinge type vertical hinged door; more than these two kinds of vertical hinged doors all have same problem; it is careless the user to occur through regular meeting, open firmly excessive, too fast at closing time, bad other article of door knob or door damaged.

[utility model content]

The purpose of this utility model is to provide that a kind of minute multistage spacingly opens the door, the spacing door-hinge of spacing multistage accurately.

The utility model is to adopt following scheme to realize: the spacing door-hinge structure of a kind of multisection type, comprise doorframe and movable door-hinge, it is characterized in that, the lower end of movable door-hinge is equipped with a flexible jumper that can have mating face under the level with door-hinge rotation and lower end, the following mating face of flexible jumper is provided with pit, it is on the circumference in the center of circle that described upward pit is distributed in the door-hinge axle center, one with connector holder that doorframe is fixedlyed connected on be equipped with one be in movable door-hinge under locator, this locator has mating face on the level that is adjacent to mating face under the flexible jumper, but and keep flexible jumper relative positioning device to rotate, the last mating face of described locator is provided with down pit, it is on the circumference in the center of circle that described pit down is distributed in the door-hinge axle center, and the radius of a circle of following pit along the radius of a circle at distribution place, axle center and last pit along distribution place, axle center is identical, pit can be docked after locator and flexible jumper relatively rotate an angle with following pit, and pit is built-in with spheroid with following pit in butt joint.

Further improvement as such scheme is characterized in that, described spheroid is more than half to submerge and go up pits, and maintains the part spheroid pit down that submerges.

Further improvement as such scheme is characterized in that, described spheroid the is more than half pits down that submerge, and maintain the part spheroid and submerge and go up pit.

Further improvement as such scheme is characterized in that, spheroid is rotary in last pit and following pit.

Further improvement as such scheme, it is characterized in that, it is the circular trough in axle center with the door-hinge that connector holder is provided with one, be used for inserting for locator, locator can be rotated in this circular trough, have long slot bore on the sidewall of described locator, then be provided with the circular hole corresponding on the circular cell wall with the slotted hole groove, one bolt passes circular hole and long slot bore and is screwed into the screwed hole that places the locating piece in the locator, and locator is fixed on the connector holder.

Operating principle of the present utility model and characteristics are described below:

1, the designed spacing door-hinge structure of multisection type of the utility model when pushing, is lived

The device that is dynamically connected rotates with door-hinge, makes spheroid sliding from the following pit at place

Go out, and rotate, slipping under the next one before the pit with last pit,

Only raise dodge gate on mating face on the locator slightly on the spheroid top, when

After rotating a predetermined angular, spheroid slips into branch again under the action of gravity of door

In cloth another following pit on same circumference, certain to rotating generation

Resistance has played certain buffering inhibition to the rotation of dodge gate, falls

Low velocity of rotation, when twisting resistance during less than resistance, spheroid then rests on down

In the pit, play the spacing effect that pauses; Certainly, when door-hinge rotates,

Spheroid also may be to skid off from last pit, and rests on down in the pit,

Before pit rode on the spheroid on the next one, ended at flexible jumper on the spheroid top

Following bonding surface on and dodge gate is raised slightly, when flexible jumper rotates

Behind the certain angle, it is sliding again at ball to be distributed on the same circumference another pit

On the body, hinder or the spacing effect that pauses and can play dodge gate equally.

Because door needs to finish the action of repeatedly lifting and landing in closing course,

Cushioned excessive external force, thereby realized that the action of switch door divides multistage to finish,

Avoided the switch door overexert, when excessive, bad other things of door knob or damage

Bad door itself.

2, the designed spacing door-hinge structure of multistage of the utility model is more than half with spheroid

Volume embeds to be gone up in the pit, and spheroid can not deviate from from last pit at least,

Thereby make spheroid when motion, can not break away from upper and lower pit simultaneously, and be stuck in

Between the upper and lower bonding surface, influence the rotation of door-hinge; Equally also can be with spheroid

Under embedding, more than half volumes in the pit, spheroid at least can not taken off from following pit

Go out, can not be stuck between the upper and lower bonding surface in the time of guaranteeing the spheroid motion equally.

3, the spheroid in the designed spacing door-hinge structure of multistage of the utility model, pit

Can rotate in pit, the friction when moving to reduce spheroid makes switch

When door is more laborsaving, and can reduce the wearing and tearing of spheroid and ambient medium.

4, the designed spacing door-hinge structure of multistage of the utility model, locator can

Rotate in the circular trough on the connector holder, in that locator and connector holder is solid

Before fixed, can locator be rotated according to concrete needs and adjust certain angle,

To guarantee of the butt joint of upper and lower pit in each suitable spacing position.
