Abstract
The invention discloses a kind of crack between a door and its frame finger pinch device being used for child protection safety, comprise fixed block; Described fixed block is provided with crack between a door and its frame blocking mechanism and infrared sensor; Described crack between a door and its frame blocking mechanism comprises sleeve; Control circuit and electromagnet are installed in described sleeve; Described control circuit is connected with electromagnet by circuit; Described electromagnet is connected with spring; Described spring and crack between a door and its frame stop that rod is connected; Described crack between a door and its frame stops that rod and spring junction are provided with iron block.The present invention has and plays available protecting children hand and be not jammed injured, thus child protection safety, and structure is simple, advantage easy 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 being used for child protection safety.
Background technology
Fond of play is the nature of children; a lot of child can like hiding behind the door, often hand can be placed in crack between a door and its frame, and other people do not note making door crush children's hand at closing time; also do not have a kind of child protection that is used for prevent hand by the protective device pressed from both sides at present, 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 being used for child protection safety, have and play available protecting children hand and do not clamped by door injured, thus child protection safety, and structure is simple, advantage easy to use.
In order to achieve the above object, technical scheme of the present invention is:
Be used for the crack between a door and its frame finger pinch device of child protection safety, comprise fixed block; Described fixed block is provided with crack between a door and its frame blocking mechanism and infrared sensor; Described crack between a door and its frame blocking mechanism comprises sleeve; Control circuit and electromagnet are installed in described sleeve; Described control circuit is connected with electromagnet by circuit; Described electromagnet is connected with spring; Described spring and crack between a door and its frame stop that rod is connected; Described crack between a door and its frame stops that rod and spring junction are provided 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 crack between a door and its frame; can not note because of other people; make door crush children's hand at closing time, have and play available protecting children hand and do not clamped by door injured, thus child protection safety; and structure is simple, advantage easy to use.

Fig. 2 is internal construction schematic diagram of the present invention;
Fig. 3 is the using state schematic diagram that the present invention is arranged on doorframe.
Detailed description of the invention
Embodiment 1
The present invention is as shown in Figure 1, Figure 2 and Figure 3 a kind of is used for the crack between a door and its frame finger pinch device of child protection safety, comprises fixed block 1; Described fixed block 1 is provided with crack between a door and its frame blocking mechanism 2 and infrared sensor 3; Described crack between a door and its frame blocking mechanism 2 comprises sleeve 4; Control circuit 6 and electromagnet 7 are installed in described sleeve 4; Described control circuit 6 is connected with electromagnet 7 by circuit; Described electromagnet 7 is connected with spring 8; Described spring 8 and crack between a door and its frame stop that rod 5 is connected; Described crack between a door and its frame stops that rod 5 and spring 8 junction are provided with iron block 9.
The crack between a door and its frame finger pinch device of the present embodiment is arranged on door 11 and place, doorframe 10 junction doorframe by screw, when being arranged on the infrared sensor 3 on fixed block 1 downside, when sensing that there is a hand comes in contact at crack between a door and its frame place, by signal feedback to the control circuit 6 on crack between a door and its frame blocking mechanism 2, the power supply on electromagnet 7 is disconnected by control circuit 6, the crack between a door and its frame that original electromagnet 7 holds stops the iron block 9 that rod 5 studs with, after power-off, crack between a door and its frame stops that the iron block 9 of edge on rod 5 is ejected by the elastic force of spring 8, crack between a door and its frame stops that rod 5 also ejects sleeve 4 simultaneously, to door 11 1 resistances, make not close, otherwise, when infrared sensor 3 does not sense that there is a thing at crack between a door and its frame place, control circuit 6 on crack between a door and its frame blocking mechanism 2 does not disconnect the power supply on electromagnet 7, electromagnet 7 keeps the state of the iron block 9 holding edge on crack between a door and its frame stop rod 5 always, crack between a door and its frame is stopped, and the iron block 9 of edge on rod 5 cannot by the ejection of spring 8, also be that crack between a door and its frame stops that rod 5 also cannot eject sleeve 4, door 11 can normally be closed.
The application of the invention, when children hide behind the door, is placed in crack between a door and its frame by hand because of carelessness; can not note making door crush children's hand at closing time because of other people, have and play available protecting children hand and do not clamped by door injured, thus child protection safety; and structure is simple, advantage easy to use.
Content described in this manual embodiment is only enumerating the way of realization of inventive concept; should not being regarded as of protection scope of the present invention is only limitted to the concrete form that embodiment is stated, protection scope of the present invention also and conceive the equivalent technologies means that can expect according to the present invention in those skilled in the art.
