Specific embodiment
The technical solution of the utility model is further elaborated with reference to the accompanying drawing.
A kind of hydraulic door-closer shown in Figure 1 for the utility model, including having shell 1, the energy of sealing inner cavity 11
The piston body 2 for doing horizontal rectilinear motion in inner cavity 11, the transmission mechanism for driving piston body 2 to move are reached, is filled in inner cavity 11
Full hydraulic oil, piston body 2 divide inner cavity 11 for the first cavity 111 and the second cavity 112, are provided on piston body 2 for controlling
Hydraulic oil is only capable of the check valve 21 flowed into the first cavity 111 from the second cavity 112, between piston body 2 and the one end of shell 1
One is additionally provided with for providing the elastic component 3 that piston body 2 is moved towards 111 direction of the first cavity.In the present embodiment, door, which is in, closes
When closed state, the first cavity 111 is in the smallest state of volume, and when starting to open the door, piston body 2 is under the drive of the transmission mechanism
It is moved towards the direction of the second cavity 112 of compression, when the external world, stopping exerts a force on the door, under the action of elastic component 3, piston body 2
It is moved towards the direction of the first cavity 111 of compression.
Referring to figure 1 and figure 2, gs-oil separator 4 is provided in inner cavity 11, gs-oil separator 4 includes in the horizontal direction
The outer tube 41 of extension and two end caps 43 for being separately positioned on 41 extending direction both ends of outer tube are opened on each end cap 43
Equipped with so that the venthole 431 that 41 inside of outer tube is connected to outside, oily when the door closer of the utility model is kept in motion
Air outside gas separating device 4 is stirred as minute bubbles, and part minute bubbles enter in outer tube 41, when door closer is in static shape again
When state, the minute bubbles convergence in outer tube 41 becomes air pocket, and above-mentioned air pocket will not enter in hydraulic oil, with door closer
Constantly working, the gas in inner cavity is gradually all collected into inside outer tube 41, and the bubble in hydraulic oil is gradually all separated,
Therefore more and more steady when piston body 2 is run, user experience is improved, and the structure of the door closer is simple, easy to accomplish, cost
It is cheap.
Shown in referring to figs. 2 and 3, gs-oil separator 4 further includes that setting is in outer tube 41 and same horizontally extending
Inner tube 42, outer tube 41, inner tube 42 and two end caps 43 surround cricoid air storing cavity 44 jointly, and gs-oil separator 4 also has edge
The perforative hydraulic oil channel 45 of length direction, hydraulic oil channel 45 is enclosed by inner tube 42 to be set, if offering capable person in inner tube 42
The through-hole 46 that air storing cavity 44 is connected to hydraulic oil channel 45.Since the air in inner cavity 11 can't be especially more, air storing cavity
44 volume does not need to be arranged very big, and correspondingly, the volume of gs-oil separator 4 is also smaller, is easily placed in inner cavity 11.
When the hydraulic door-closer of the utility model remains static, part bubble in hydraulic oil can via through holes 46 into
Entering in air storing cavity 44 and converging becomes air pocket, and above-mentioned air pocket will not enter in hydraulic oil, when the door closer is in movement
When state, the air outside gs-oil separator 4 is stirred as minute bubbles, and part minute bubbles enter in hydraulic oil channel 45, when closing door
When thinking highly of new remain static, the minute bubbles in hydraulic oil channel 45 enter in air storing cavity 44, with the continuous work of door closer
Make, the gas in inner cavity 11 is gradually all collected into air storing cavity 44, and the bubble in hydraulic oil is gradually all separated.
Specifically, gs-oil separator 4 is arranged in the second cavity 112, and piston body 2 corresponds to when compressing the first cavity 111
The state that door leaf is automatically closed, after the gas in hydraulic oil is all collected by gs-oil separator 4, being automatically closed for door leaf will more
Steadily.And gs-oil separator 4 is installed on piston body 2 and moves with the movement of piston body 2, is conducive to gs-oil separator 4
Collect the bubble in hydraulic oil.
As a preferred embodiment, the one end of hydraulic oil channel 45 is connect with check valve 21, therefore the second chamber
When hydraulic oil in body 112 is flowed into the first cavity 1, it is bound to by gs-oil separator 4, so that the gas in hydraulic oil
Bubble is easier to enter in air storing cavity 44.
Specifically, shown in Figure 1, elastic component 3 is the pressure spring being arranged in the second cavity 112, the both ends difference of pressure spring 3
It contradicts on the one end of piston body 2 and inner cavity 11, structure is relatively simple.The middle part of pressure spring 3 has an accommodation space, oil gas point
It is arranged in the accommodation space from device 4, so that the structure of the hydraulic door-closer of the utility model is more compact.Pressure spring 3 is moving
When the air pocket outside gs-oil separator 4 can be stirred as minute bubbles, minute bubbles can flow into oil gas point with hydraulic oil
From in device 4.
Shown in referring to figs. 2 and 3, outer tube 41 and inner tube 42 are all cylinder, the axial line of outer tube 41 and the axis of inner tube 42
Heart line is collinearly arranged.In this way setting so that installation gs-oil separator when it is more convenient, do not need carry out angle adjustment.For same
Purpose, through-hole 46 is uniformly arranged in the circumferential direction of inner tube 42.
When piston body 2 compresses the second cavity 112, the hydraulic oil in the second cavity 112 flows into the first chamber through check valve 21
Sky of the hydraulic oil through piston body 2 Yu inner cavity 11 in body 111, when piston body 2 compresses the first cavity 111, in the first cavity 111
Clearance flow enters in the second cavity 112, and in certain embodiments, hydraulic door-closer is provided with for being connected to the first cavity 111 and second
The connecting pipe of cavity 112, to change drag size when switch gate.
In the present embodiment, transmission mechanism includes being arranged on piston body 2 and along the rack gear of 2 direction of motion of piston body arrangement
22 and the gear 5 that is rotatably arranged on hydraulic door-closer and is meshed with rack gear 22.5 turns of the opening and closing energy band moving gear of door
It is dynamic, and then drive the movement of piston body 2.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
