During closed state, cam 312 is abutted against close to 313 side of nock with pull rod 342, and pull rod 342 is partially housed in nock 313, convex
312 side away from nock 313 of wheel is abutted against with roller 336.
When opening the door, axostylus axostyle 311 is rotated with door-hinge, and rotates cam 312, and edge 314 pushes pull rod 342, makes the
One pulling plate 330 and the second pulling plate 340 are moved to the side for pushing part 350, and then make to push part 350 to the side of elastic component 200
Slide and compression elastic piece 200, while elastic component 200 is pushed 350 1 elastic force of part, and then give the first pulling plate 330 and second
Pulling plate 340 1 pushes power, pull rod 342 is pushed edge 314 and axostylus axostyle 311 is produced single-revolution power, and then plays the work of shutdown
With.
When at closing time, axostylus axostyle 311 is rotated with door-hinge, and turns round cam 312, and edge 314 pushes roller 330 manually,
The first pulling plate 330 and the second pulling plate 340 is moved to away from the side for pushing part 350, and then make to push part 350 to away from elasticity
200 1 Slideslip of part, and then elastic component 200 is discharged, meanwhile, the elastic force that part 350 is also subject to elastic component 200 is pushed, promotes axis
Bar 311 produces turning power, and produces shutdown power-assisted.
Meanwhile slided on by rotating stem 423 make abutting protrusion 422 in multiple joint faces 413 one, and select
Abutted against with one in multiple step surfaces 412 to selecting property, and regulating part 420 is pushed sliding part 410 and slide, and then adjusted
Save the torque of the decrement, i.e. adjusting door closing device 10 of elastic component 200.
Above-mentioned door closer 10 at least has the following advantages：
(1) slided on make regulating part 420 in multiple joint faces 413 by rotating regulating part 420 one, and selectively
Ground is abutted against with one in multiple step surfaces 412, and regulating part 420 is pushed sliding part 410 and slided, and then regulation elasticity part
200 decrement, while moment variations amount when regulating part 420 is abutted with adjacent step surface 412 can be pre-set, Ke Yigen
Regulating part 420 is connected on corresponding step surface 412 according to the torque size of required shutdown, the power of accurate adjusting door closing device 10
Square, improves the precision of 10 torque size of adjusting door closing device.
(2) side of the end cap away from cylinder 140 is equipped with scale, and the quantity of scale is equal with the quantity of step surface 412, each
Scale corresponds to a step surface 412, and regulating part 420 is equipped with cue mark, and cue mark is located at regulating part 420 and stretches out adjusting
On the side in hole 120, when regulating part 420 and a step surface 412 abut against, the position of cue mark and the position of a scale
Put corresponding, door closer 10 can rotate stem 423 according to the torque size of required shutdown, cue mark is directed toward corresponding
Scale, improves the efficiency of the torque of adjusting door closing device 10.
(3) blowout patche of thrust bearing 430 and seat ring are abutted against with regulating part 420 and pivot pin 440 respectively, and regulating part 420 is worn
Arranged on thrust bearing 430, during regulating part 420 is rotated, thrust bearing 430 can reduce regulating part 420 and pivot pin 440
Between frictional force.
(4) pivot pin 440 is fixedly connected with cylinder 140, and is abutted against with the seat ring of thrust bearing 430, prevents that seat ring is direct
Abutted against with end cap 150, and make what end cap 150 bore regulating part 420 to push power.
(5) card slot is offered on shell 100, sliding part 410 is equipped with snap fit tabs 415, snap fit tabs 415 and card slot phase
Engage and prevent sliding part 410 from rotating, so that regulating part 420 promotes sliding part 410 to slide.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, its description is more specific and detailed, but simultaneously
Cannot therefore it be construed as limiting the scope of the patent.It should be pointed out that come for those of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
