The utility model can effectively prevent cold air from leaking.
Description
(1) technical field
The utility model relates to a kind of door closer.
(2) background technology
When cold-storage door is closed, the door-plate weather strip must fit like a glove with doorframe, can prevent effectively that so just cold air from escaping to overflow, the at present more existing door closer that is used for closing automatically door, exist the power of closing strong and the process of closing the door is not steady, make the door-plate weather strip not fit like a glove, cause cold air to leak with doorframe.
(3) summary of the invention
The utility model exists closing force not strong for the door closer that solves present use, thereby causes the cold-storage door sealing not strong, and making has the excessive problem of cold air; The technical scheme that is adopted is: the hydraulic pressure bucket is movably connected on body one end and can relatively rotates, hydraulic stem freely wore fixed cover, piston is fixed in the hydraulic stem other end, one spring housing is located on the hydraulic stem, one end is against fixed cover other end abuts against plunger, piston, spring and part hydraulic stem place the hydraulic pressure bucket, and fixed cover is fixed in the openend of hydraulic pressure bucket, are marked with hydraulic oil in the hydraulic pressure bucket;
Guide peg one end is movably connected on the other end of body and can relatively rotates, and hydraulic stem one end and guide peg flexibly connect and can relatively rotate, and the guide peg other end is provided with pulley.
Be provided with C type hook, use with the pulley coupling.
Guide peg is the L type, and hydraulic stem one end is movably connected on the L type infall of guide peg.
Hydraulic pressure bucket and body one end be connected with guide peg one end and the body other end be connected with being connected of hydraulic stem one end and guide peg all be that pin connects.
Fixed cover and body junction are provided with rubber washer, and the contact portion of hydraulic stem and fixed cover is provided with rubber washer.
The end that hydraulic stem is connected with piston is provided with external screw thread, and a nut is engaged in and presses piston on the external screw thread.
Good effect of the present utility model has: when door was opened, hydraulic stem stretched out the hydraulic pressure bucket, moved on the piston, and guide peg and body are rectangular and remain unchanged the bigger elastic force of spring compression generation simultaneously; The process of closing the door is: when door closes certain angle, pulley is run into the C type hook on the doorframe, the chute that pulley is prolonging in the C type hook slowly slides, along with the angle of guide peg and body becomes big gradually, the elastic force of spring slips in the hydraulic pressure bucket hydraulic stem, force door-plate to be pressed into doorframe thereby produce inside pressure, equal until door-plate with doorframe.Can find out that therefrom the utility model is big and steadily in the power of inwardly oppressing at closing time, and door-plate weather strip and doorframe are fitted like a glove, can prevent effectively that cold air from escaping to overflow.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 2 is the utility model hydraulic pressure bucket, piston, fixed cover and hydraulic stem decomposition texture schematic diagram;
Fig. 3 is the view of the utility model when door is opened;
Fig. 4 is the view of the utility model when door is closed.
(5) specific embodiment
Embodiment: referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of hydraulic pressure door closer, hydraulic pressure bucket 10 usefulness pins 55 are movably connected on body 20 1 ends and can relatively rotate, hydraulic stem 11 freely wore fixed cover 21, piston 30 is located at and is provided with externally threaded hydraulic stem 11 1 ends, one nut 12 is engaged in external screw thread, and piston 30 is fixed in hydraulic stem 11.
One spring 40 is sheathed on the hydraulic stem 11, one end is against fixed cover 21 other end abuts against plunger 30, piston 30, spring 40 and part hydraulic stem 11 place hydraulic pressure bucket 10, fixed cover 21 is fixed in the openend of hydraulic pressure bucket 10, at this moment spring 40 maintains certain elastic force, is marked with hydraulic oil in the hydraulic pressure bucket 10;
Guide peg 50 1 ends can relatively rotate with the other end that pin 51 is movably connected on body 20, and the L type infall of hydraulic stem 11 1 ends and guide peg 50 flexibly connects and can relatively rotate with pin 53, and guide peg 50 other ends are provided with a pulley 60 by pin 54.
Fixed cover 21 and body 20 junctions are provided with rubber washer 80, and the contact portion of hydraulic stem 11 and fixed cover 21 is provided with rubber washer 81.
Be provided with C type hook 70 again.
Use of the present utility model is: the utility model is applicable to revolving door, and promptly Men a side is connected with doorframe by the loose-leaf hinge;
Body 20 is fixed in away from flexibly connecting the door-plate upper edge of a side with doorframe, and it is corresponding with pulley 60 that C type hook 70 is fixed in the doorframe upper edge;
If the closed condition of being initially, at this moment state is: hydraulic stem 11 is a straight line with guide peg 50,20 of hydraulic pressure bucket 10 and bodies maintain certain angle, when door is unlocked, pulley 60 slowly down skids off from C type hook 70, simultaneously, the angle of guide peg 50 and hydraulic stem 11 slowly diminishes and hydraulic stem 11 is up drawn at leisure, spring 40 is compressed and the close at leisure body 20 of hydraulic pressure bucket 10 at leisure, skid off C type hook 70 until guide peg 50 and hydraulic stem 11 rectangular also pulleys 60, at this moment, the angle of guide peg 50 and hydraulic stem 11 remains unchanged and hydraulic pressure bucket 10 is parastate with body 20, pulley 60 is away from C type hook 70, door can freely rotate on doorframe, is opening;
The process of closing the door is, when door is closed to certain angle, the C type that pulley 60 on the door-plate is run on the doorframe is linked up with 70 inboards, the chute that pulley 60 is prolonging C type hook 70 slowly slides, the elastic force of spring 40 begins to work, and hydraulic stem 11 slowly is pressed into hydraulic pressure bucket 10, and guide peg 50 slowly becomes big with the angle of hydraulic stem 11, its generation force door-plate to be pressed into doorframe gradually to internal pressure, equal until door-plate with doorframe.
From opening the door and the process of closing the door can be found out, owing to there is hydraulic oil, the elastic force that makes spring 40 produce is very steady, and at closing time, the impact force that doorframe is subjected to door-plate is very steady, but the adhesive power of closing back door plate is very strong.Therefore, it is strong and the process of closing the door is steady that the utility model is closed power, makes door-plate weather strip and doorframe fit like a glove, and can not cause cold air to leak.
