Abstract
The utility model discloses a door slot hand-pinch-prevention device for protecting the safety of a child. The device comprises a fixing block, wherein a door slot blocking mechanism and an infrared sensor are mounted on the fixing block; the door slot blocking mechanism comprises a sleeve; a control circuit and an electric magnet are mounted in the sleeve; the control circuit is connected with the electric magnet through a circuit; the electric magnet is connected with a spring; the spring is connected with a door slot blocking rod; and an iron block is mounted at the joint of the door slot blocking rod and the spring. The door slot hand-pinch-prevention device has the advantages as follows: a hand of the child is effectively protected from being pinched and wounded, the safety of the child is protected, the structure is simple, and the use is convenient.
Description
Technical field
The utility model relates to a kind of crack between a door and its frame finger pinch device, is 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 crack between a door and its frame, and other people do not note can making at closing time door to crush children's hand; also there is no 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.
The utility model content
The purpose of this utility model 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 by door, do not clamped injured, thereby child protection safety, and advantage simple in structure, easy to use.
In order to achieve the above object, the technical solution of the utility model is:
A kind of crack between a door and its frame finger pinch device that is used for child protection safety, comprise fixed block; Crack between a door and its frame blocking mechanism and infrared sensor are installed on described fixed block; 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 stops that with crack between a door and its frame rod is connected; Described crack between a door and its frame stops that rod and spring junction are equipped with iron block.
The beneficial effects of the utility model are: by using the utility model; 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 at closing time the door crush children's hand, have play effective child protection hand by door, do not clamped injured, thereby child protection safety; and advantage simple in structure, easy to use.
The accompanying drawing explanation
Fig. 1 is the utility model external structure schematic diagram;
Fig. 2 is the utility model internal construction schematic diagram;
Fig. 3 is that the utility model is arranged on the use view on doorframe.
The specific embodiment
The utility model as shown in Figure 1, Figure 2 and Figure 3 is 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; Crack between a door and its frame blocking mechanism 2 and infrared sensor 3 are installed on 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 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 stops that with crack between a door and its frame rod 5 is connected; 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 the present embodiment is arranged on door 11 and doorframe 10 place, junction doorframes by screw, when the infrared sensor 3 be arranged on fixed block 1 downside, sense the crack between a door and its frame place hand when contact arranged, by signal feedback to the control circuit 6 on crack between a door and its frame blocking mechanism 2, the power supply disconnected on electromagnet 7 by control circuit 6, the crack between a door and its frame that original electromagnet 7 holds stops the iron block 9 studded with on rod 5, after cutting off the power supply, crack between a door and its frame stops that the iron block 9 of edge on rod 5 is by the elastic force ejection of spring 8, 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 crack between a door and its frame blocking mechanism 2 does not disconnect the power supply on electromagnet 7, electromagnet 7 keeps holding the state that crack between a door and its frame stops the iron block 9 of edge on rod 5 always, make crack between a door and its frame stop that the iron block 9 of edge on rod 5 can't pass through the ejection of spring 8, be also that crack between a door and its frame stops that rod 5 also can't eject sleeve 4, door 11 can normally be closed.
By using the utility model; when children hide behind the door; because of carelessness hand is placed in crack between a door and its frame; can not note making at closing time door crush children's hand because of other people; have and play effective child protection hand and do not clamped injured by door; thereby child protection safety, and advantage simple in structure, easy to use.
The described content of this manual embodiment is only enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reaches the equivalent technologies means that design can be expected according to the utility model in those skilled in the art.
