On, the other end of the support rod is provided with sliding block, and the sliding block is buckled in the sliding slot of sliding slot, and the sliding block can be along sliding slot
Direction sliding, the spring for being constantly in compressive state is provided between the support rod and pedestal；It is described when pushing door-plate open
Support rod spring is continued to squeeze, when people leave no longer to door apply thrust when, effect of the support rod in spring thrust
It is lower to push away door-plate to the position of doorframe, until door-plate is closed completely with doorframe.
Preferably, the sliding slot of the sliding slot is provided with buffer spring, the activity of the buffer spring far from one end of pedestal
End is mounted with buffer stopper.
Preferably, when door in the closure state, buffer spring is applied to the power of sliding block and spring is applied to the power of sliding block
It is contrary and equal in magnitude.
Preferably, the sliding block is the end that support rod is fixed on by a universal joint.
Preferably, the spring is the middle part for being fixed on support rod.
Preferably, the outside of the sliding slot is removably mounted with cover board, and there are for support rod and sliding block on the cover board
Between the movable bar shaped long hole of connection structure.
Compared with prior art, the beneficial effects of the present invention are:
1. the present invention is provided a kind of with the device that door-plate is automatically closed, the Purely mechanical by simply designing
Door closer have the advantages that structure is simple, manufacturing cost is low, easy to maintain, service life is long.
2. the present invention is provided with buffer spring far from one end of pedestal in the sliding slot of sliding slot, and in the movable end of buffer spring
It is mounted with buffer stopper, which effectively prevents sliding block and contact with the hard of sliding slot, effectively extends its service life.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure, pedestal 1, sliding slot 2, sliding block 3, universal joint 4, buffer spring 5, buffer stopper 6, support rod 7, spring 8.
Specific embodiment
The present invention is described in further detail below in conjunction with Detailed description of the invention and specific embodiment mode.
Referring to Fig. 1, a kind of mechanical automatic door closer, including pedestal 1, sliding slot 2, support rod 7 and spring 8, pedestal 1 and sliding
Slot 2 is located at the same horizontal position and is mutually perpendicular to, and is respectively disposed on doorframe and door-plate, and the fixed section of support rod 7 is hinged on
On pedestal 1, the other end of support rod 7 is provided with sliding block 3, and sliding block 3 is buckled in the sliding slot of sliding slot 2, and sliding block 3 can be along sliding slot 2
Direction sliding, the spring 8 for being constantly in compressive state is provided between support rod 7 and pedestal 1；When pushing door-plate open, support
Bar 7 continues to squeeze to spring 8, and when people, which leaves, no longer applies thrust to door, support rod 7 is under the action of 8 thrust of spring
Door-plate is pushed away to the position of doorframe, until door-plate is closed completely with doorframe.
The sliding slot of sliding slot 2 is provided with buffer spring 5, buffer spring far from one end of pedestal 1 as a preferred technical solution,
