Description
Technical field
the utility model relates to a kind of door closer, particularly a kind of can automatic door opening and the door closer of closing the door.
Background technology
the basic role of door closer is automatically closed by door, can also steadily close to protect doorframe and door leaf.In prior art, the course of work of door closer is usually as follows: door leaf is opened by people, connecting rod and the relative pinion rotation launching to drive door closer of cranking arm, because the piston body of door closer inner chamber is meshed by rack and pinion, therefore piston body does rectilinear motion in the lumen by spring-compressed under the drive of gear; After people enters, the reset force of spring promotes piston body and does rectilinear motion in opposite direction, and gear rotates in opposite direction under the drive of tooth bar, connecting rod and crank arm folded toward thus closed by door leaf.The shortcoming of this door closer is as follows: the unlatching of door leaf needs Manual-pushing, first will put down and going to push again, using inconvenience when holding thing in incomer's hand; Incomer frequently contacts door leaf, fast spreading disease, uses unhygienic.
Summary of the invention
for the problems referred to above, the purpose of this utility model is to provide a kind of automatic door closer, and it can automatic door opening and closing the door.
for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
a kind of automatic door closer, comprising:
door closer body, it is arranged on door leaf, described door closer body comprises the housing with inner chamber, be arranged at the piston in described inner chamber actively, be located in the closer axle in described inner chamber rotationally, be arranged at the gear on described closer axle, top be located between described piston and housing for the spring by piston reset, hydraulic oil is full of in described inner chamber, the external surface of described piston is provided with the tooth bar extended along its length, described wheel and rack is meshed to drive piston to do rectilinear motion in the lumen, the end of described closer axle is passed described housing and extends to outside housing, one of them end of described closer axle is fixedly connected with a driven bevel gear,
inductor, it is arranged on doorframe for picking up the signal of human body near door leaf;
motor, its to be arranged on door leaf and after receiving described signal startup optimization, the output shaft of described motor is fixedly connected with an initiatively conical gear, and described active conical gear is meshed with described driven bevel gear;
linkage, its one end is connected on the end of described closer axle, the other end is rotationally connected with doorframe.
preferably, described motor is installed on described housing.
preferably, described inductor is microwave sensor or infrared inductor.
preferably, described driven bevel gear and connecting rod are fixedly connected on two relative ends of described closer axle respectively.
preferably, described linkage comprises cranks arm and connecting rod, described in the one end of cranking arm rotate with one end of connecting rod and be connected, described in the other end of cranking arm be fixedly connected on one of them end of closer axle, the other end of described connecting rod is rotationally connected with doorframe.
operating principle of the present utility model is as follows:
when people is near door leaf, inductor senses the signal that people is close and this signal is sent to motor, motor starts startup optimization after receiving this signal, motor is by initiatively conical gear and driven bevel gear drive closer axle to rotate, crank arm and to rotate under the drive of closer axle thus relatively with connecting rod to launch, door leaf is opened, simultaneously because rack and pinion is meshed, piston body does rectilinear motion in the lumen, and spring is compressed; After people enters, inductor is responded to less than the close signal of people, motor is out of service, piston does rectilinear motion in opposite direction under the effect of spring restoring force, gear driven closer axle rotates in opposite direction, crank arm and to rotate in opposite direction with closer axle thus to draw close in opposite directions with connecting rod, door leaf cuts out.
the utility model adopts above structure, and tool has the following advantages: by the signal that inductor pickup human body is close, motor is run automatically and drives door leaf to open; After door is opened, move by the effect driven plunger of reset force thus door leaf cuts out automatically, the automatic opening and closing of door leaf can be realized, easy to use; Motor is by initiatively conical gear and the rotation of driven bevel gear driven wheel, and motor can be installed on door closer housing, and outsides cover of electric machinery can be wholely set with housing, easy for installation, and small product size is little.

Detailed description of the invention
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, can be easier to be those skilled in the art will recognize that to make advantage of the present utility model and feature thus more explicit defining is made to protection domain of the present utility model.
shown in composition graphs 1, Fig. 2, a kind of automatic door closer, comprising:
door closer body, it is arranged on door leaf, described door closer body comprises the housing 1 with inner chamber 11, be arranged at the piston (not shown) in described inner chamber 11 actively, be located in the closer axle 22 in described inner chamber 11 rotationally, be arranged at the gear 21 on described closer axle 22, top be located between described piston and housing 1 for the spring (not shown) by piston reset, hydraulic oil is full of in described inner chamber 11, the external surface of described piston is provided with the tooth bar extended along its length, described gear 21 is meshed with tooth bar to drive piston to do rectilinear motion in inner chamber 11, the end of described closer axle 22 is passed described housing 1 and extends to outside housing 1, one of them end of described closer axle 22 is fixedly connected with a driven bevel gear 23,
inductor 5, it is arranged on doorframe for picking up the signal of human body near door leaf;
