The invention relates to a hydraulic cylinder with a hydraulic hinge, which comprises a cylinder body (1), a piston (2) and a piston rod (5), wherein the piston (2) and a piston rod (5) are arranged in the inner chamber of the cylinder body (1). The hydraulic cylinder is characterized in that a check ring (4) is arranged between the piston (2) and a shoulder (11) of the piston rod (5); a through hole (9) and a blind hole (8) are formed in the piston (2); liquid can flow in the through hole (9) in two directions; the blind hole (8) serves as a cylinder body of an positive displacement pump; the check ring (4) can move between the piston (2) and the shoulder (11), and can cover part of the blind hole (8); one end of the piston rod (5) is connected with the piston (2); the other end of the piston rod (5) is connected with a guide sleeve (6) and a Y-shaped oil seal (7); and an O-shaped oil seal (3) is embedded in the piston (2). The invention has the advantages that as the positive displacement hydraulic pump is arranged on the piston, the size of the cylinder body is greatly reduced; as the internal structure of a piston cylinder is simplified, the purposes of small and exquisite appearance, simple operation and large force are realized; and the hydraulic cylinder can be changed and improved in various manners, so that the application range is wide.
Description
Technical field
The present invention relates to the oil hydraulic cylinder of a kind of oil hydraulic cylinder, particularly a kind of hydraulicefficiency hinge.Belong to hinge accessory technical field.
Background technique
At present, hinge is widely used in reality production and life.The hinge of existing technology has two kinds of structures: a kind of is the mechanical elasticity structure, and this elastic mechanical structure produces strong wallop closing to 60 quick closedowns when spending, and makes door send ear-piercing interference noise.Another kind is the structure of band hydraulic damping cylinder, and this structure has overcome the noise interference of closing the door fast and bringing, but because its oil hydraulic cylinder adopts Twin channel or three Room types, therefore have following shortcoming: the volume of liquid cylinder entity is big, consumptive material is many, cost is high.
Summary of the invention
The technical issues that need to address of the present invention, promptly the object of the invention is in order to overcome the shortcoming that existing hinge oil hydraulic cylinder volume is big, part is many, consumptive material is many, cost is high, a kind of oil hydraulic cylinder of hydraulicefficiency hinge to be provided.
Technical problem of the present invention can solve through taking following measure:
The oil hydraulic cylinder of hydraulicefficiency hinge; Comprise cylinder body and the piston and the piston rod that are positioned at inner chamber of cylinder block; It is characterized in that: be provided with back-up ring between the shoulder of piston and piston rod, be provided with an access hole that two-way circulates and the blind hole as the displacement pump cylinder body in the piston, back-up ring can move between piston and shoulder; Back-up ring can cover the part of blind hole: an end of piston rod and piston be connected, the other end is connected with " Y " type oil sealing with guide pin bushing, is with " O " shape oil sealing in the piston; Be provided with two guide pin bushings in the cylinder body, two guide pin bushings seize on both sides by the arms " Y " type oil-sealing sleeve on piston rod and hydraulic oil be encapsulated in the cylinder body by the panel beating reducing together; The bottom of cylinder body is provided with and hinged mounting hole; The exposed parts of piston rod is provided with the hole or the riveted joint shoulder that are installed in the hinge joint part; The size of ring washer can cover the major part of the whole and blind hole of access hole, makes blind hole become a container with liquid entering hole and liquid outlet; The maximum moving distance of ring washer is provided by the shaft shoulder on the piston rod.
The present invention has following beneficial effect:
1, to be different from the characteristics of existing technology be that cylinder body is a single channel in the present invention; Utilize blind hole and back-up ring on the piston to constitute the volume cylinder; Be equivalent on piston, be provided with volume-type hydraulic pump; The volume of cylinder body is reduced greatly, simplified the piston cylinder inner structure, realized the purpose small and exquisite, simple, that power is big.Have simple in structure, install and remove advantage easily and efficiently.
2, the present invention encapsulates all equipment with panel beating reducing distortion on cylinder body; Make assembly technology simple, beautiful shape is small and exquisite, and the part that the mounting hole of cylinder base setting and piston rod expose constitutes the hinge joint position; Make hydraulic cylinder structure compact, the inornate simple and easy and attractive in appearance harmony of appearance.
3, the present invention can make various variations and remodeling, has wide range of applications.

Fig. 2 is the axis projection figure of Fig. 1.
Fig. 3 is the back-up ring of Fig. 1 and the partial enlarged drawing of piston joint
Embodiment
Below in conjunction with specific embodiment the present invention is specifically described.
Specific embodiment:
Fig. 1, Fig. 2 and Fig. 3 constitute a specific embodiment of the present invention.Can know that from Fig. 1 present embodiment comprises cylinder body 1 and piston that is positioned at cylinder body 1 inner chamber 2 and piston rod 5; One end of piston rod 5 and piston 2 be connected, the other end is connected with " Y " type oil sealing 7 with guide pin bushing 6; Be with " O " shape oil sealing 3 in the piston 2; The shoulder 11 of piston rod 5 is provided with back-up ring 4, is provided with an access hole that two-way circulates 9 and the blind hole 8 as the displacement pump cylinder body in the piston 2.
In the present embodiment: two guide pin bushings 6 are seized " Y " type oil sealing 7 on both sides by the arms and are enclosed within on the piston rod 5 and hydraulic oil is encapsulated in the cylinder body 1 by the panel beating reducing together.The bottom of cylinder body 1 is provided with and hinged mounting hole.The exposed parts of piston rod 5 is provided with the hole or the riveted joint shoulder that are installed in the hinge joint part.The size of ring washer 4 can cover the major part of the whole and blind hole 8 of access hole 9, makes blind hole 8 become a container with liquid entering hole and liquid outlet.
Can know from Fig. 3: the maximum moving distance of ring washer 4 is provided by the shaft shoulder on the piston rod 5 11.
Key of the present invention is to be provided with in the piston volume-type hydraulic pump.This volume-type hydraulic pump is made up of back-up ring 4, the blind hole 8 that is positioned at piston 2.According to Principle of Mechanical Designing: the moving or change the pump of liquid being pressed to oil drain out by inlet port of the seal container that constitutes by housing.Like Fig. 1, shown in Figure 3, in the practical application, when hinge is closed; Piston 2 moves to the opening end of cylinder body 1, and the liquid in the cylinder body 1 offers 4 one back pressures of back-up ring, impels back-up ring 4 to move away piston 2, make and form an interspace between the two; Access hole 9 conductings on the piston 2 at this moment, because the existence of back-up ring 4, so liquid can only slowly pass through; The flow stream velocity of access hole 9 of flowing through is slower; Reach piston 2, piston rod 5 and slowly move, the torsion spring power of resiliently deformable on the hinge is slowly discharged, reach the purpose that closing noise was slowly closed, reduces even eliminated to hinge.In addition, when piston rod 5 was compressed into cylinder body 1, flow was washed ring washer 4 open, fast through access hole 9, so when hinge was opened, resistance was very little, has the effect of opening the door fast.
