Abstract
The invention discloses a door crack hand-clamping prevention device for protecting safety of children. The door crack hand-clamping prevention device comprises a fixed block which is provided with a door crack resisting mechanism and an infrared sensor. The door crack resisting mechanism comprises a sleeve, and a control circuit and an electromagnet are installed in the sleeve. The control circuit is in circuit connection with the electromagnet, the electromagnet is connected with a spring, and the spring is connected with a door crack resisting bar. An iron block is arranged at the joint between the door crack resisting bar and the spring. The door crack hand-clamping prevention device has the advantages of effectively protecting hands of the children from being clamped and injured, protecting the safety of the children, and being simple in structure and convenient to use.
Description
Technical field
The present invention relates to a kind of crack between a door and its frame finger pinch device, be specifically related to a kind of crack between a door and its frame finger pinch device that is used for child protection safety.
?
Background technology
Fond of play is children's nature; a lot of children can like hiding behind the door, often hand can be placed in the crack between a door and its frame, and other people do not have attention can make at closing time door crush children's hand; also do not have at present a kind of protective device that child protection prevents that hand from being pressed from both sides that is used for, the present invention produces thus.
?
Summary of the invention
The object of the present invention is to provide a kind of crack between a door and its frame finger pinch device that is used for child protection safety, have play effective child protection hand do not clamped by door injured, thereby child protection safety, and advantage simple in structure, easy to use.
In order to achieve the above object, technical scheme of the present invention is:
A kind of crack between a door and its frame finger pinch device that is used for child protection safety comprises fixed block; Crack between a door and its frame blocking mechanism and infrared sensor are installed on the described fixed block; Described crack between a door and its frame blocking mechanism comprises sleeve; Control circuit and electromagnet are installed in the described sleeve; Described control circuit links to each other with electromagnet by circuit; Described electromagnet links to each other with spring; Described spring stops that with crack between a door and its frame rod links to each other; Described crack between a door and its frame stops that rod and spring junction are equipped with iron block.
The invention has the beneficial effects as follows: the application of the invention; when children hide behind the door; because of carelessness hand is placed in the crack between a door and its frame; can not note because other people; make at closing time the door crush children's hand, have play effective child protection hand do not clamped by door injured, thereby child protection safety; and advantage simple in structure, easy to use.
Description of drawings
Fig. 1 is external structure schematic diagram of the present invention;
Fig. 2 is internal construction schematic diagram of the present invention;
Fig. 3 is that the present invention is installed in the use view on the doorframe.
The specific embodiment
Such as a kind of crack between a door and its frame finger pinch device that is used for child protection safety of Fig. 1, Fig. 2 and the present invention shown in Figure 3, comprise fixed block 1; Crack between a door and its frame blocking mechanism 2 and infrared sensor 3 are installed on the described fixed block 1; Described crack between a door and its frame blocking mechanism 2 comprises sleeve 4; Control circuit 6 and electromagnet 7 are installed in the described sleeve 4; Described control circuit 6 links to each other with electromagnet 7 by circuit; Described electromagnet 7 links to each other with spring 8; Described spring 8 stops that with crack between a door and its frame rod 5 links to each other; Described crack between a door and its frame stops that rod 5 and spring 8 junctions are equipped with iron block 9.
The crack between a door and its frame finger pinch device of present embodiment is installed on door 11 and place, the doorframe 10 junction doorframe by screw, when the infrared sensor 3 that is installed on fixed block 1 downside, sense the crack between a door and its frame place hand when contact arranged, with signal feedback to the control circuit 6 on the crack between a door and its frame blocking mechanism 2, by the power supply on the control circuit 6 disconnection electromagnet 7, the crack between a door and its frame that original electromagnet 7 holds stops the iron block 9 that studs with on the rod 5, crack between a door and its frame stops that the iron block 9 of edge on the rod 5 is by the elastic force ejection of spring 8 after cutting off the power supply, crack between a door and its frame stops that rod 5 also ejects sleeve 4 simultaneously, give door 11 1 resistances, a pass is not gone up; Otherwise, infrared sensor 3 is not sensed the crack between a door and its frame place when thing is arranged, control circuit 6 on the crack between a door and its frame blocking mechanism 2 does not disconnect the power supply on the electromagnet 7, electromagnet 7 keeps holding the state that crack between a door and its frame stops the iron block 9 of edge on the rod 5 always, make crack between a door and its frame stop that the iron block 9 of edge on the rod 5 can't be by the ejection of spring 8, also be that crack between a door and its frame stops that rod 5 also can't eject sleeve 4, door 11 can normally be closed.
The application of the invention when children hide behind the door, is placed on hand in the crack between a door and its frame because of carelessness; can not crush children's hand because other people not to note not making at closing time door, have play effective child protection hand do not clamped by door injured, thereby child protection safety; and advantage simple in structure, easy to use.
The described content of this manual embodiment only is enumerating the way of realization of inventive concept; protection scope of the present invention should not be regarded as only limiting to the concrete form that embodiment states, protection scope of the present invention also reaches in those skilled in the art conceives the equivalent technologies means that can expect according to the present invention.
