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 the position of cue mark and a scale
Set 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
Set on thrust bearing 430, during rotating regulating part 420, 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 seat ring direct
It abuts against with end cap 150, and so that end cap 150 is born regulating part 420 and 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
It fastens and sliding part 410 is prevented to rotate, so that regulating part 420 pushes sliding part 410 to slide.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies 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, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
