Abstract
The utility model relates to a hydraulic flow regulating valve for sports equipment. The utility model is used to solve the difficulty that the flow of the hydraulic fluid of existing sports equipment is not regulable. An involute cylindrical cam is assembled on a valve body, and the size of an oil channel in the valve body can be changed by regulating the cam, and the purpose of controlling the flow can be obtained. The utility model has the advantages that the continuous regulation of the flow between oil-hydraulic cylinders is realized, and output resistances can be regulated according to the physic quality conditions of a user. The utility model also has the advantages of convenient operation and high stability.
Description
The utility model belongs to a kind of fluid flow regulator valve, mainly is applicable to the control of flow between two oil hydraulic cylinders on the sports equipment.
Body-building all has a sources of resistance that produces resistance with sports equipment, and people overcome the purpose that resistance reaches exercise repeatedly by muscular strength.The sources of resistance of existing equipment is normally by weight, spring, generations such as hydraulic pressure.Use the sports equipment of hydraulic pressure as sources of resistance, fluid flow is nonadjustable in its oil hydraulic cylinder, and promptly this sports equipment can only produce constant resistance.Thereby, bring some inconvenience just for year order and physical discrepant user, the people of physically alive can not get that exercise intensity should be arranged, and the people of poor physical capacity is difficult to operation again.
The purpose of this utility model just provides a kind of adjustable flow control valve, operates this valve and can produce different resistances.
The utility model is finished like this: adorn the valve of a control flow rate between two oil hydraulic cylinders, two oil hydraulic cylinders link to each other with valve body by screw thread, have an oil duct that the oil duct of two oil hydraulic cylinders is communicated with in the valve body.Main points are that the cam mechanism that is used for control flow rate is housed between the oil duct of valve body, and this cam mechanism has one and is assemblied in the hole, valve body garden, and rotating column type cam.When rotating cam, the interstitial site of cam and hole wall can change, and then valve body internal oil channel size also changes thereupon, reaching control flow rate, and then the purpose of control resistance size.
Advantage of the present utility model is: realized the continuous adjusting of flow between oil hydraulic cylinder, output resistance can change according to user's health.Easy and simple to handle, the stability height.
Accompanying drawing and drawing explanation:
Fig. 1 is an exploded perspective view of the present utility model.
Fig. 2 is a sectional elevation of the present utility model.
Fig. 3 is a longitudinal section of the present utility model.
Fig. 4 is the structural drawing of the utility model cam.
Fig. 5 is that the A of cam shown in Figure 4 is to view.
Fig. 6 is user mode figure of the present utility model.
Below in conjunction with accompanying drawing the utility model embodiment is elaborated.
Fig. 1 has described embodiment's formation, its assembly process is such, oil ring 4 is enclosed within earlier on the oil ring groove on the cam 3, again the cam of working good is placed in the hole, garden of valve body 5, then clasp 2 is buckled on the garden hole wall of valve body 5 in the ring shaped slot, then knob 1 is enclosed within on the four rib projectioies of cam 3, gets final product in the screw with countersink head screw 6 screw-in valve bodies 5 sides at last.
Fig. 2 has described embodiment's oil duct situation, and two oil ducts 7,8 of two oil hydraulic cylinders 10,11 are communicated with to get up by oil duct 9.Have the hole, garden in the neutral position of oil duct 9, cam 3 is housed on the hole, garden.Fig. 3, Fig. 4, Fig. 5 have represented the structure of cam 3 and the assembling situation of cam 3 and valve body 5, and a garden axle 12 that protrudes is arranged at its cam 3 bottoms, are engaged on the shrinkage pool of bottom, hole, valve body garden the stability during with 3 rotations of assurance cam.The radius of cam 3 is designed to involute-type with the variation of angle, makes the flow control continization.
Fig. 6 has represented the stereogram after embodiment's assembling.
Claims (3)
1, a kind of flow control valve, the inside of its valve body [5] has two oil ducts [7,8] that link to each other with oil hydraulic cylinder [10,11] to be connected the oil duct [9] of oil duct [7,8] with one, it is characterized in that: go up at valve body [5] and have circular hole, assembling one rotating column type cam [3] on this circular hole with respect to oil duct [9] position intermediate.
2, flow control valve according to claim 1 is characterized in that: in cam (3) bottom one circular shaft (12) that protrudes is arranged, be engaged on the shrinkage pool of valve body circular hole bottom, and also be with a knob (1) in the top of cam (3).
