The utility model provides a kind of safety door.Said safety door comprises a body, doorframe, handle, ejector, and said handle is installed on the body, and said ejector is installed in the top of a body; Said ejector comprises fixture, motion bar, roller and torsion spring, and said fixture is fixed on the inboard top of a body, and said push rod is installed in the outside of door; Said handle comprises handle, carriage release lever, and said carriage release lever is provided with wedge and back-moving spring, is connected with push rod between the motion bar of said wedge and ejector; Hold handle at closing time, said carriage release lever moves, and said wedge drives push rod and moves upward; One end of said push rod backs down ejector, and door is normally closed, when hand unclamps from handle; Said back-moving spring moves carriage release lever, drives push rod and down moves, and an end of said push rod no longer withstands ejector; Said ejector is under the effect of torsion spring, and motion bar resets to the direction vertical with Men Ticheng.

Further describe below in conjunction with specific embodiment.

Please consult Fig. 1,2 and 3 in the lump, for the sectional view of the structural representation in the front of an embodiment of the utility model safety door and A-A and C-C sectional view.

As shown in the figure, said safety door comprises a body 1, doorframe 2, handle 3, ejector 4, push rod 5, rotation safety piece 6, torsion spring hinge 7, Fixed hinge 8, door lock 9 and push rod 10.

Said handle 3 is installed on the body 1.

Said ejector 4 is installed in the top of a body 1 inboard.

Said ejector 4 comprises fixture 41, motion bar 42, roller 43 and torsion spring.

Said fixture 41 is fixed on the top of a body 1 inboard, and said motion bar 42 is installed on the said fixture 41 through torsion spring.Said roller 43 is installed in the top of said motion bar 42.Said push rod 5 is installed in the outside of door, and an end is connected on the motion bar 42 of apical organ spare, and the other end and handle 3 contact.

The length of said apical organ spare motion bar 42 is a little slightly longer than normal adult's wrist.

Said handle 3 comprises inside and outside two grip 31 of door, carriage release lever 32, back-moving spring 33, the auxiliary rotation of handle finger 34, finger 35, the auxiliary circulator 36 of door lock.

Said carriage release lever 32 is installed in the middle of the chute of a body 1, two ends connect respectively outdoors with door in handle 31.The end that said carriage release lever 32 is positioned at outer side of door is provided with wedge 321, and an end and the wedge 321 of said push rod 5 contact.One limited block 38 is set between said wedge 321 and the handle 31.The end that said carriage release lever 32 is positioned at an inboard is provided with zigzag groove (figure does not show).

Said back-moving spring 33 is set on the carriage release lever 32.Also be provided with steel ball 37 between said carriage release lever 32 and the chute.

Auxiliary circulator 36 1 ends of said door lock are installed on the door lock 9; The auxiliary rotation of said handle finger 34 1 ends are installed on the carriage release lever 32, and said finger 35 links together the other end of the auxiliary circulator 36 of said door lock and the other end of the auxiliary rotation of handle finger 34.

Said push rod 5 can be wooden or other materials for example plastics and metal or the like.

The Fixed hinge 8 of rotation safety piece is installed on the side at said door body two ends about in the of 1, will rotates safety piece 6 and be fixed on a body 1 side.

Be positioned at the other torsion spring hinge 7 that is provided with of carriage release lever on said door body 1 side.

Said torsion spring hinge 7 comprises connecting portion 71 and rotating part 72, links to each other with rotation safety piece 6 on the said connecting portion 71.

Said rotating part 72 leans an end of push rod 10.

Said push rod 10 is installed in the chute of the installation portion on a body 1 inboard, also is arranged with back-moving spring 101 on the said push rod 10.

The other end of said push rod 10 leans the end that carriage release lever 32 is positioned at an inboard.

The other end of said push rod 10 has the gradient with carriage release lever 32 zigzag grooves coupling.

The thickness of said rotation safety piece 6 is lacked about 2 millimeters than the length of ejector 4, because children's finger diameter is generally greater than 2mm.

When grasping handle at closing time, hand-motion handle 31 is to the outer side of door motion, and handle 31 drives carriage release lever 32 and moves to outer side of door; Said push rod 5 is under the effect of handle wedge 321; Up motion, thus back down the motion bar 42 of ejector 4, motion bar 42 and 1 one-tenth parallel direction of body.At this moment, door can normally be closed.

When hand when handle 3 unclamps, carriage release lever 32 to the door medial movement, drives push rod 5 and down moves under the effect of back-moving spring 33, no longer withstands the motion bar 42 on the ejector 4.When door was opened, said ejector 4 was under the effect of torsion spring 43, and roller 42 resets to and 1 one-tenth vertical direction of door body.

Therefore, when children or adult do not grasp handle at closing time, push rod 5 can not rise and back down ejector 4; The motion bar 42 of said ejector 4 withstands on the doorframe 2; Door just can not be closed, and the length of said motion bar 42 is a little slightly longer than normal adult's wrist, even therefore wrist is between door body and doorframe; Adult's wrist only can be pinched and can not be crushed, and child only has a sensation of being pressed from both sides.

And when grasping handle at closing time, if own perhaps other people finger is arranged between door body and the doorframe, then when rotation safety piece 6 touches finger; Said rotation safety piece 6 fast rotational are also compressed the rotating part 72 of torsion spring hinge 7; And the more weak relatively push rod 10 of rotating part 72 Fast Compression elastic force gets in the carriage release lever 32 zigzag grooves, thus the carriage release lever 32 of stuck handle 3, and carriage release lever 32 can not move to outer side of door; So the motion bar 42 of push rod 5 with regard to not rising and backing down ejector 4; Door body 1 just can not closed, and finger just can not crushed so, even by pinch off.

In addition, owing to can drive the rotation of door lock 9 through rotating handles 31, so handle 3 can unblank through rotation, also can be through moving the effect that safety is closed the door of playing.

In sum; The safety door that the utility model embodiment is provided is installed the ejector that resets by torsion spring that has roller at the top of door, close the door when not holding handle; When perhaps between door and the doorframe finger being arranged; Withstand doorframe through ejector, door can not be closed, thereby avoids crushing own perhaps other people finger.

More than safety door that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the technical scheme that the utility model discloses; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
