Abstract
The invention discloses a hidden type door closer capable of achieving bidirectional installation. The hidden type door closer capable of achieving bidirectional installation comprises a body, a rotating piece, a rotating arm, a rotating rod, a resetting structure, a damping structure and a locating block. The rotating piece and the rotating arm are rotationally installed on the body through the rotating rod. The rotating arm is installed on the portion, extending out from the body, of the rotating rod. The resetting structure and the damping structure are arranged in the body and connected with the rotating piece. The resetting structure generates pull force on the rotating piece all the time. The damping structure generates push force on the rotating piece all the time. The pull force is always larger than the push force. The locating block is connected with the rotating arm in a sliding manner. The rotating rod can extend out from the different sides of the body. The structures of the rotating arm installed on the different sides of the body are different. The hidden type door closer can be installed in a bidirectional lanner, and the production cost is effectively reduced.

And slide block 11 is pulled, the compression stress that spring 9 is subject to is reduced, when manpower unclamps the active force of opposite house, in 11 restoring force of oil cylinder
In the presence of door rotate to the direction closed, and with the rotation of door, the compression stress suffered by spring 9 is increasing, and opposite house is produced
Raw damping force is also increasing, and then the speed that door is closed is gradually slack-off, door is slowly shut, in whole process, oil cylinder
11 restoring force is consistently greater than the contracting power of spring 9.
Embodiment two
Embodiment two is different from embodiment one in turning arm and locating piece, and remaining structure is just the same.The embodiment
Turning arm 116 is the bar of a bending, and is being not affected by external force effect, and turning arm 116 is reached away from one end of rotating rod 8
The front of door-plate and the width extension in door-plate.Equally, when installation direction is inconsistent, the turning arm 116 needs more
Change, the structure of the turning arm 116 in the case of two kinds mirror image each other.
As shown in figs. 12-15, the locating piece 150 of the present embodiment includes housing 151, core body 152 and fixed plate 153,
The middle part of the housing 151 arranges jagged 1511, and moveable movable plate 1521 is provided with the core body 152, such as schemes
Shown in 14 and 15, the breach 1511 cooperatively forms the groove 154 coordinated with turning arm 116 with movable plate 1521, and according to tool
The installation of body needs to adjust particular location of the movable plate 1521 in breach 1511 to determine in which side formation notch
1541 so that turning arm 116 enters or skids off groove 154 from notch 1541.
When mounted, the embodiment is roughly the same with embodiment one：The installation direction of door closer is determined as the case may be,
Further determine rotating rod 8 stretches out direction, then selects the turning arm 116 being engaged, and then door closer is arranged on door-plate；
Locating piece 150 is fixed on doorframe, the movable plate 1521 then moved as needed on core body 152 is formed and turning arm 116
The notch 1541 being engaged.
Ultimate principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
The simply present invention of the personnel it should be appreciated that the present invention is not restricted to the described embodiments, described in above-described embodiment and description
Principle, without departing from the spirit and scope of the present invention the present invention also have various changes and modifications, these change and
Improvement is both fallen within the range of claimed invention.The protection domain of application claims by appending claims and its
Equivalent is defined.
