Link 70 comprises pedestal 71, chuck 72 and axle center 73, and wherein pedestal is connected with door, and the axle center is fixed on the pedestal, and chuck is enclosed within the outside, axle center rotationally, and hinged with connecting rod 22.
Floating piston assembly 30 comprises floating piston 31, spring 32 and joint ring 33, and wherein floating piston places the spring front end, and joint ring is contained in the outer rim of floating piston.
Adjusting part 50 is to be provided with two adjustment holes 51 vertically in main body 10 outsides, and this adjustment hole communicates with store oil cavity in the main body, and a set screw 52 respectively is housed in each adjustment hole.
Connector 60 comprises adapter sleeve 61 and Connection Block 62, and the adapter sleeve threaded one end is connected in main body 10 ends, and the other end and Connection Block are hinged.
As seen from the above technical solution, the utility model has overcome the defective of existing door closer, has realized the combination of door closer profile, structure and function.Because whole device is a tubular body, itself and doorframe all can be made two dimension with the connecting portion of door and rotate, thereby rotate flexible, capable of expansion and contraction.Also adopt hydraulic structure, thereby have good shock-absorbing capacity, make the process of closing the door very steady, realized that nothing is at closing time impacted, noiselessness owing to it.The utility model can be widely used in the various public and civilian construction.
Description of drawings
Fig. 1 is a schematic perspective view of the present utility model.
Fig. 2 is a structure sectional view of the present utility model.
The specific embodiment
Fig. 1 shows profile of the present utility model, Fig. 2 then shows its concrete structure, as shown, fluid pressure type door check of the present utility model is provided with a tubular body 10, and main body one end is provided with external screw thread 11, and the main body outside is provided with two adjustment holes 51 of one with it vertically, an adjustment hole is shorter, another is longer, and adjustment hole is communicated with the main body internal cavity, forms oil circuit.Two ends are respectively equipped with main piston assembly 20 and floating piston assembly 30 in the main body, wherein, main piston assembly 20 comprises main piston 201, connecting rod 202, joint ring 203, oil sealing 204 support rings 205 and clasp 206, wherein, main piston is contained in interlinking lever end, it is axially inboard fixing by nut 207, be drilled with oily circulation port on the main piston, can realize the unidirectional oil that follows with 208 effects of thin type pad, it axially is equipped with copper pad 208 in the outside successively, interior anti-collision body 209, X-shaped sealing ring 210, the first decompression seat 211, joint ring 203, oil sealing 204, support ring 205, the second decompression seat 212, dust scraping ring 213, outer anti-collision body 214 and clasp 206, clasp 26 is contained in body end, and above-mentioned parts all are contained on the connecting rod.Connecting rod stretches out from main body, its other end and rotatable link 70 are hinged, this link comprises pedestal 71, chuck 72 and axle center 73, wherein pedestal base plate 711 is screwed on the door, be fixed with axle center 73 on the ear seat 712 vertical with base plate, chuck is enclosed within the outside, axle center rotationally, and hinged by pin 74 with connecting rod 202, thereby connecting rod not only can stretch in main body, also can carry out bidimensional and rotate.Floating piston assembly 30 comprises floating piston 31, spring 32 and joint ring 33, and wherein floating piston places the spring front end, and the X-shaped joint ring is contained in the outer rim of floating piston, for preventing piston wear, in the piston outer rim wear ring 34 is housed also.Between main piston assembly and the floating piston assembly hydraulic oil 40 is housed, hydraulic oil can circulate between main body oil storage chamber and the formed oil circuit of adjustment hole.The main body outside is provided with adjusting part 50, and this adjusting part is in two axial adjustment holes 51 of main body 10 outsides a set screw 52 to be housed respectively, and one of them set screw is used to regulate the piston speed of service of starting stage of closing the door, and the speed of closing the door of this moment is very fast.Piston speed of service when another set screw is used for adjustment doors and is about to close, the speed of closing the door of this moment is slow.The oil-in place that the lower end of two set screw places adjustment hole to communicate with main body rotates the internal circulating load that set screw can change oil, and the oil mass in the main body is changed, thus the speed of service of regulating piston.By floating piston assembly one end connector 60 is housed in main body, this connector comprises adapter sleeve 61 and Connection Block 62, the adapter sleeve threaded one end is connected in main body 10 ends, its other end sealing, axle sleeve 63 is housed in the hole of this end end, adapter sleeve and Connection Block can rotate adapter sleeve around bearing pin by a bearing pin 64 being passed ear seat 621 on axle sleeve and the Connection Block and hinged.Connection Block 62 usefulness screws are connected with doorframe.
Operating principle of the present utility model is understood with reference to Fig. 2, when door is opened, connecting rod 202 drives main piston 21 floating piston direction motion in pipe, hydraulic oil circulates by the circulation port on adjustment hole and the main piston simultaneously, make the speed of service of connecting rod and door very fast, that is the Shi Buhui that opens the door is subjected to any restriction, meanwhile, floating piston is subjected to oil pressure to promote the compression spring, and open angle can reach more than 120 degree.When door was closed, floating piston 31 moved to the main piston direction under spring 32 effects, and main piston moves under the oil pressure effect laterally, connecting rod is ejected from main body, the thin type pad 208 of main piston one side is attached to the main piston end face, and hydraulic oil can only circulate by adjustment hole, under the set screw effect, beginning one section, to follow oil mass big, movement velocity is fast, when residue 15 is spent left and right sides crack between a door and its frame, follows oil mass and falls sharply, the speed of closing the door is slowed down, and lasts till last closure always.
