The specific embodiment
Below in conjunction with accompanying drawing 1-7, the specific embodiment of the technical solution of the utility model is described in further detail.
Embodiment: a kind of door closer comprises electric device 7 and the hydraulic means 10 that links to each other with electric device 7.Electric device 7 comprises motor 1 and gear-box 2.The output shaft 9 of motor 1 is provided with bevel gear 6, is connected with gear 5 on the bevel gear 6, is socketed with the axle 3 that links to each other with the connecting rod of door on the gear 5, and axle 3 is arranged in the gear-box 2 by bearing 4, is fixedly connected with cam 8 on the described axle 3; The rotation of motor 1 drives axle 3 by bevel gear 6 and gear 5 and rotates, thus the switch of control gate.
Hydraulic means comprises housing 19, is provided with cavity 34 in the housing 19, is provided with piston 20 in the cavity 34.Piston 20 is connected with described housing 19 inwall slipper seals, and cavity 34 is isolated into left cavity 32 and right cavity 33; One end of cavity 34 is provided with rear end cap 17, and the other end is provided with drive end bearing bracket 22.Drive end bearing bracket 22 movable sealings are socketed in the front end of piston 20.The front end of piston 20 is by pivot pin 24 and described cam 8 corresponding rollers 23.The utility model has adopted cam 8 and roller 23 transferring power, used Archimedes' principle, in the manually-operated of hand push door, having overcome present technology causes the dynamics of pushing increasing because of the structure that adopts gear and tooth bar, reach the effect that the dynamics that pushes can be more and more littler, made things convenient for old man and child.Piston 20 is in the described cavity 34 and with cavity 34 movable sealings and is connected, and cavity 34 is isolated into left cavity 32 and right cavity 33.Be provided with the spring 18 that is in the right cavity 33 between piston 20 and the rear end cap 17, play the effect that promotes piston 20.Piston 20 is provided with the oil pipe a14 that communicates with described left cavity 32 and right cavity 33, is provided with one-way cock 31 between oil pipe a14 and the described left cavity 32.Realize the storage and the release of spring 18 energy by the rectilinear motion of piston 20, when piston 20 moved compression spring 18 backward, one way valve 31 was opened, and hydraulic oil flow in the left cavity 32 from right cavity 33.
Because piston 20 itself just has volume, piston 20 makes the smaller volume of cavity 34 in the process that advances, moreover, filled up hydraulic oil in the cavity 34, guarantee the volume same so were it not for cavity 34, piston 20 propellings are not so, in order to guarantee that hydraulic means 10 can operate as normal, in piston 20, be provided with hole 37, be provided with plunger 39 in the hole 37, be provided with spring b40 between plunger 39 and the piston 20, described plunger 39 is connected with described piston 20 inwall movable sealings.Piston 20 is provided with hole a36, and plunger 39 is provided with hole b38, and the end of described spring b40 is connected in the a36 of hole, and the other end is connected in the b38 of hole.Hole a36 and hole b38 play support spring b40 effect.So in the process that piston 20 advances, plunger 39 is under pressure and advances in hole 37, then can form the space of a compensation, when piston 20 is subjected to the effect outward movment of spring 18, then plunger 39 also moves outside hole 37 simultaneously, thereby makes volume not change all the time.
Be equipped with sealing ring 21 between piston 20 and housing 19 inwalls and the drive end bearing bracket 22, and be provided with sealing ring 21 between piston 20 inwalls and the plunger 39, guarantee that hydraulic oil seepage can not take place.
When switching on first, electromagnet 27 drives control valve 15 by lever 25 and compresses sealing ring a35, realizes the cut-out to oil circuit; Motor 1 is converted into cam 8 rotations simultaneously, and cam 8 drives the piston 20 that is connected with roller 23 and moves backward, and hydraulic oil flows by one way valve 31 and flows into left cavity 32 from right cavity 33; When motor 1 antiport or cam 8 were met peak, because the reason that oil circuit cuts off, piston 20 transfixions, hydraulic means 10 breaks away from electric device 7, thereby realizes the function of door closer.During outage, electromagnet 27 drives control valve 15 by lever 25 and unclamps sealing ring a35, realizes the unimpeded of oil circuit,
