Abstract
For a non-return locator for self-closing doors, comprise bearing and non-return leg.Bearing is fixed on door leaf inner surface bottom, non-return leg has free end, the link hinged with bearing and is connected the brace portion of described free end and link, when non-return locator is in running order, the work plane of free end and earth surface, produce friction, at bearing, under the acting in conjunction of non-return leg and door leaf, self-closing doors is made to be fixed on required open position.
Description
Technical field
The present invention relates to a kind of non-return locator be arranged on automatic close rotary door.
Background technology
In daily life, people install door engine additional usually on door leaf, under the effect not having other external force, door engine can drive door leaf to rotate around the jointed shaft of door leaf and doorframe, complete automatic door-closing, eliminate the action of closing the door, but this gives as needed continuous transport article or other work needing door leaf to stay open state a period of time to make troubles.
At Chinese patent application prospectus, the positioner that a kind of antitheft door of building keeps opening-wide state is disclosed in CN 2878617Y, described positioner is made up of supporting leg, supporting leg seat, supporting leg twisted axis, supporting leg off working state detent mechanism, its thrust of closing the door compressing supporting leg produced by the original closing device of building door, supporting leg is made to produce reaction force, two dynamic balances, thus make door leaf be parked in required open position.When needs are closed, lift supporting leg with pin, make supporting leg rest on the inner surface of door leaf, extruding retainer spring compresses one end of supporting leg, make one end that rubber pad is housed of supporting leg can not leave door leaf inner surface, make supporting leg can not bring impact to the normal use of door.But because supporting leg adopts a kind of thinner bar material, even if add rubber pad for increasing the frictional force of supporting leg and ground on supporting leg end, but the contact area because of supporting leg and ground is less, the frictional force produced is less, thus make the location of door leaf unreliable, just obtain positioner location when ground is more smooth invalid.When needs use supporting leg to locate door leaf, people is needed to kick ear with pin hook, supporting leg is put down, and supporting leg be extruded retainer spring extruding be positioned in door leaf surface, make the action putting down supporting leg more difficult, simultaneously when regaining supporting leg, meeting opposite house under retainer spring squeezing action produces collision, and the impact several times of supporting leg opposite house can cause the damage of door leaf surface.Because supporting leg off working state detent mechanism physical dimension is less, easily damaged in Reusability, not only make supporting leg can not be in off working state more reliably, and make the complex structure of non-return locator.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of structure simpler, more convenient operation, and locating effect is better, can effectively solve because supporting leg impact several times door leaf surface to cause the non-return locator of damage to door leaf surface.
For solving the problem, the invention provides a kind of non-return locator for self-closing doors, this non-return locator comprises bearing and non-return leg, wherein non-return leg has free end, the link hinged with bearing and is connected the brace portion of described free end and link, when non-return locator is in running order, the work plane of described free end and earth surface, the free end of described non-return leg is provided with thrust.
Owing to being provided with thrust on the free end of non-return leg, when non-return locator is in running order, increase the contact area on non-return leg and ground, effectively increase frictional force like this, thus improve the reliability to door leaf non-return location, simultaneously in the process putting down supporting leg, because the existence of thrust, footwear and supporting leg contact surface increase, and make supporting leg put down action easier, and need not add non-return leg in addition and put down device.In addition, if make the width of thrust side direction be greater than the lateral width in brace portion, contact area can be increased further.In addition, also can on the free end of non-return leg affixed brake pad, to increase the friction factor of contact surface.
As a further improvement on the present invention, can arrange crisscross groove on the end face of brake pad with work plane makes contacting of itself and ground more effective.
As a further improvement on the present invention, the quality of non-return leg free end can be strengthened, the quality of free end is made to be greater than the quality of link, and make the center of gravity of non-return leg near free end, when non-return locator is in off working state, because center of gravity is near free end, under gravity, make non-return leg more stable be in non-work state, and other auxiliary body need not be added in addition, also simplify the structure of non-return locator simultaneously.
Further improve as of the present invention, a positioning boss can be set on bearing, when regaining non-return leg, by positioning boss, supporting leg being positioned, thus avoiding non-return leg causes door leaf surface in folding and unfolding process damage to the collision of door leaf surface.

Detailed description of the invention
[Fig. 1 to Fig. 3 shows the first embodiment of non-return locator.As shown in Figure 1 to Figure 3, non-return locator comprises bearing and non-return leg, wherein non-return leg has free end, the link hinged with bearing and is connected the brace portion of free end and link, when non-return locator is in running order, the work plane of free end and earth surface, increase the work plane of free end and the contact area on ground because the free end of non-return leg being provided with thrust, thus increase the frictional force between non-return leg and ground, and make the location of door leaf more reliable; Simultaneously in the process putting down supporting leg, because the existence of thrust, footwear and supporting leg contact surface increase, and make supporting leg put down action easier, and need not add non-return leg in addition and put down device.In addition, the width because of thrust side direction is greater than the lateral width in brace portion, can increase contact area further, and the groove of crisscross setting on work plane will make the contact on itself and ground more effective.In the present invention, the quality of non-return leg free end is strengthened, the quality of free end is made to be greater than the quality of link, and make the center of gravity of non-return leg near free end, when non-return locator is in off working state, because center of gravity is near free end, under gravity, make non-return leg more stable be in non-work state, and other auxiliary body need not be added in addition, also simplify the structure of non-return locator simultaneously.A positioning boss is set in the present invention on bearing, when regaining non-return leg, by positioning boss, supporting leg is positioned, thus avoiding non-return leg causes door leaf surface in folding and unfolding process damage to the collision of door leaf surface.
Fig. 4 shows the second embodiment of non-return locator.As shown in Figure 4, affixed brake pad on the free end of non-return leg, to increase the friction factor of contact surface.The groove of crisscross setting on the end face of brake pad in the present invention will make the contact on itself and ground more effective.
By reference to the accompanying drawings embodiments of the present invention are described in detail above, but the present invention is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, many variations can also be made to it.Therefore, protection scope of the present invention be not only confined to above-mentioned example, all technical schemes belonged under thinking of the present invention all belong to protection scope of the present invention.
