Specific embodiment
Below with reference to attached drawing, the utility model will be further described, it should be noted that following embodiment is with this
Premised on technical solution, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is simultaneously
It is not limited to the present embodiment.
As shown in Figs 1-4, a kind of door closer, including pedestal 1, lever piece 2, magnetic part 3, electromagnet 4 and movable part 5;Institute
It states lever piece 2 and is rotatably connected at the pedestal 1 and using the junction with pedestal 1 as balance pivot 21, the lever piece 2
It is that boundary is divided into two sides with balance pivot 21;The magnetic part 3 is connected to the side 23 of the lever piece 2, and with the electromagnet 4
Position it is corresponding, the weight of the other side 22 of the total weight and lever piece 2 of the side 23 and magnetic part 3 of the lever piece 2
Measure that unequal (in the installation direction of the present embodiment, the total weight of the side 23 of the lever piece 2 and magnetic part 3 is greater than described
The weight of the other side 22 of lever piece 2);When the electromagnet 4 is powered, the magnetic part 3 and the magnetic phase of the electromagnet 4
It inhales, the other side 22 of the lever piece 2 can fasten with the movable part 5;The other side 22 when the magnetic disappearance of electromagnet 4
It is separated with movable part 5.
The working principle of above-mentioned door closer is: door closer is generally fixed on the doorframe of fire resistant doorsets, springy liquid
Pressure energy storage device is fixedly connected with door leaf on one side, and the other end connects door closer, and when door leaf is opened, hydraulic device is in energy storage state.
In the present embodiment, the other end of hydraulic device is connected to the movable part.Under normal circumstances, electromagnet 4 is in energization shape
The other side 22 of state, 4 magnetic attracting of magnetic part 3 and electromagnet, the lever piece 2 has a downwarp in the magnetic power that electromagnet 4 provides
It rises.At this time if necessary to open door leaf, first open door leaf, movable part 5 moves under the drive of connecting rod, when be moved to it is described
When 22 corresponding position of the other side, movable part 5 and the other side 23 engage, and the movable part 5 after engaging cannot live in the horizontal direction
Dynamic, then the other end of connecting rod can not be movable in the horizontal direction, so that hydraulic device is fixed on energy storage state, door leaf is obtained
To be fixed on opening state.When fire condition occurs, electromagnet loses power supply supply, and magnetism disappears, and is losing magnetic power
Afterwards, the other side is moved toward opposite direction, to separate with movable part.After losing outer power limit, the hydraulic dress with elastic potential energy
Release elastic energy is set, door leaf is automatically closed.
Above-mentioned door closer, which only passes through a few components such as pedestal, lever piece, magnetic part, electromagnet and movable part, can be achieved with
The function of door leaf fast automatic closing when fire is easily opened and fixed, occurred to door leaf under normal circumstances, and structure is simple, installs
Journey is efficient and convenient, and operating method is also easily understood, and helps to save transportation cost, human cost and production cost.
Further, the lever piece 2 and the movable part 5 are all made of plastic material and are made.Existing door closer component
It is generally made of metal material, the frictional force between lever piece and movable part made of metal material is big, is not easy after engaging point
From.Using lever piece and movable part made of plastic material in the present embodiment, frictional force between the two can be greatly reduced, is made
It obtains in the case where no magnetic power, lever piece and movable part can be made to separate by the movement of lever piece itself, further
Guarantee after simplifying structure, door closer still can effectively realize the function being automatically closed.
In the present embodiment, the one side of the other side 22 of the lever piece 2 be equipped with groove 221, the movable part 5 with it is described
The opposite one side of groove 221 is equipped with protrusion 51, and when the electromagnet is powered, the protrusion 51 can be caught in the groove 221.
In the present embodiment, the lever piece 2 step structure thin in thick middle, both ends.
In the present embodiment, the pedestal 5 has open cavity, and the lever piece 2, magnetic part 3 and electromagnet 4 are all provided with
In the cavity, the electromagnet 4 is corresponding with the side of magnetic part 3 towards the cavity inside, and the movable part 5 is located at
Outside the pedestal 5.
In the present embodiment, the magnetic part 3 is fixedly connected with the side 23 of the lever piece 2 by screw 6.
In the present embodiment, the lever piece 2 and the junction of the pedestal 5 are equipped with the corresponding pin hole 10 in position, use
It ships and resell on another market and realizes being rotatably connected lever piece 2 and pedestal 5 across the pin hole.
In the present embodiment, the side 23 of the lever piece 2 is equipped with screw hole 231, and the nail rod of a screw 7 passes through the spiral shell
Nail hole 231 is fixedly connected on the pedestal 5, and elastic component 8 is equipped between the magnetic part 3 and the nut of the screw 7.Pass through spiral shell
The setting of nail and elastic component when electromagnet restores magnetic again, can be inhaled with electromagnet again after being re-energised for magnetic part
It closes and further power-assisted is provided, in the present embodiment, the elastic component 8 uses compressed spring.
Further, the door closer further includes shell 9, the pedestal 5, lever piece 2, magnetic part 3, electromagnet 4 and work
Moving part 5 is set in the shell 9, and the movable part 5 can make opposite sliding along the length direction of the shell 9, and described
Shell 9 is equipped with the interconnecting piece 52 stretched out outside shell 9.Shell limits the scope of activities of movable part, so that movable part and lever
Part is easy to again through the engaging of mobile and lever piece after being detached from.
For those skilled in the art, it can be provided various corresponding according to above technical solution and design
Change and modification, and all these change and modification, should be construed as being included in the utility model claims protection scope it
