Abstract
The utility model provides an adjustable double speed hydraulic hinge comprising a hinge support bracket. The inner part of the hinge support bracket is hinged with a hydraulic cylinder. The hydraulic cylinder is composed of a cylinder body and a piston arranged in the cylinder body. The cylinder body is provided with a hydraulic-oil return passage. An oil inlet and an oil outlet of the hydraulic-oil return passage are respectively arranged at the end part of the cylinder body at both sides of the piston. A second oil inlet is also arranged between the oil inlet and the oil outlet of the hydraulic-oil return passage to be connected with the hydraulic-oil return passage. The hydraulic-oil return passage is provided with a flow control device. The utility model has the advantages of double speed, adjustable speed and convenient operation, and is used for connecting and mounting the cabinet door.
Description
Technical field
The utility model relates to a kind of hydraulicefficiency hinge, is meant a kind of adjustable double speed hydraulicefficiency hinge that is used for the connection of cabinet door especially.
Background technology
At present, a large amount of hydraulicefficiency hinges that use connect cabinet door and cabinet frame in high-grade wardrobe or file cabinet, can the impact force of buffer tank door when closing, reduce and close the sound that door sends, traditional hydraulicefficiency hinge is a hinged hydraulic cylinder in hinge bracket, utilize the one way valve conducting when the cabinet door is opened on the piston, hydraulic oil can open door by the another side of one way valve from the fast flow speed and direction piston in one side of piston fast; One way valve when closing the cabinet door on the piston disconnects, hydraulic oil can only by be arranged on hydraulic oil return flow line in the cylinder body from one side of piston with the another side of slower velocity flow to piston, thereby closing of cabinet door played cushioning effect.The hydraulic oil return flow line of traditional hydraulicefficiency hinge is single channel, and the size of passage sets in production and processing, can not adjust according to actual needs and close a speed, has awkward deficiency.
Summary of the invention
The utility model is at the deficiencies in the prior art, a kind of double speed is provided, and can regulates hydraulic oil back-flow velocity, a kind of adjustable double speed hydraulicefficiency hinge easy to use as required.
The purpose of this utility model is achieved in that a kind of adjustable double speed hydraulicefficiency hinge, comprise hinge bracket, in hinge bracket, be hinged with hydraulic cylinder, hydraulic cylinder is made up of cylinder body and the piston that is arranged in the cylinder body, cylinder body is provided with the hydraulic oil return flow line, the oil-in of hydraulic oil return flow line, oil-out are separately positioned on the cylinder ends on piston both sides, wherein: also be provided with second oil-in between the oil-in of described hydraulic oil return flow line, the oil-out and be communicated with, on the hydraulic oil return flow line, be provided with flow regulator with the hydraulic oil return flow line.
Flow regulator described in the above-mentioned adjustable double speed hydraulicefficiency hinge is arranged on the rear end of the cylinder block corresponding with the hydraulic oil return flow line.
Another group flow regulator can also be set at the cylinder side wall corresponding with oil-in in the above-mentioned adjustable double speed hydraulicefficiency hinge, increase speed adjustable range.
Flow regulator described in the above-mentioned adjustable double speed hydraulicefficiency hinge can be made up of adjusting rod, joint ring, and the adjusting rod front end is that head is regulated in taper, and joint ring is fixed on the adjusting rod periphery; Be provided with installing hole at the rear end of the cylinder block corresponding with the hydraulic oil return flow line, adjusting rod is arranged in the installing hole, and part is threaded between adjusting rod and the cylinder body, and the taper of adjusting rod front end is regulated head and stretched in the hydraulic oil return flow line.
After the utility model adopts said structure,, can realize hydraulic oil backflow double speed control first quick and back slow, thereby make the cabinet door lower, reach better buffering effect in the back segment speed of closing by middle part second oil-in is set on the hydraulic oil return flow line; Simultaneously, by flow regulator being set, can adjust the back-flow velocity of hydraulic oil as required easily, to satisfy different instructions for uses in the hydraulic oil return flow line.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model.
Among the figure: head, 7-installing hole are regulated in 1-hinge bracket, 2-hydraulic cylinder, 3-cylinder body, 4-piston, 5-hydraulic oil return flow line, 51-oil-in, 52-oil-out, 53-second oil-in, 6-flow regulator, 61-adjusting rod, 62-joint ring, 63-taper.
The specific embodiment
Consult shown in Fig. 1, adjustable double speed hydraulicefficiency hinge of the present utility model, comprise hinge bracket 1, in hinge bracket 1, be hinged with hydraulic cylinder 2, hydraulic cylinder 2 is made up of cylinder body 3 and the pistons 4 that are arranged in the cylinder body 3, cylinder body 3 is provided with hydraulic oil return flow line 5, the oil-in 51 of hydraulic oil return flow line 5, oil-out 52 is separately positioned on cylinder body 3 ends on piston 4 both sides, oil-in 51 in hydraulic oil return flow line 5, also being provided with second oil-in 53 between the oil-out 52 is communicated with hydraulic oil return flow line 5, be equipped with flow regulator 6 in cylinder body 3 rear ends corresponding with corresponding cylinder body 3 sidewalls of oil-in 51 with hydraulic oil return flow line 5, flow regulator 6 is by adjusting rod 61, joint ring 62 is formed, adjusting rod 61 front ends are that taper regulates 63, and joint ring 62 is fixed on adjusting rod 61 peripheries; Be provided with installing hole 7 in cylinder body 3 rear ends corresponding with hydraulic oil return flow line 5, adjusting rod 61 is arranged in the installing hole 7, and part is threaded between adjusting rod 61 and the cylinder body 3, and the taper of adjusting rod 61 front ends is regulated 63 and stretched in the hydraulic oil return flow line 5.
When the utility model specifically uses,, can make taper regulate 63 and more stretch in the hydraulic oil return flow line 3, the circulation area of hydraulic oil return flow line 3 is reduced, make the back-flow velocity of hydraulic oil slack-off when inside rotation adjusting rod 61; When to inner rotary adjusting rod 61, can make taper regulate 63 and in hydraulic oil return flow line 3, outwards withdraw from, the circulation area of hydraulic oil return flow line 3 is increased, thereby the back-flow velocity of hydraulic oil is accelerated.Adjust the back-flow velocity that two groups of flow regulators 6 all can change hydraulic oil, increase a speed adjustable range of closing of hydraulicefficiency hinge.
