Abstract
The utility model discloses a connecting device. According to the connecting device, a tubing head is sleeved with a connecting head, the tubing head penetrates through an elastic sleeve, a pressure spring is arranged between the tubing head and the elastic sleeve, a guiding pin is arranged between the connecting head and the elastic sleeve, a shrinkage spring is arranged between the connecting head and the guiding pin, and a sealing ring is arranged on the tubing head. The sealing ring automatically presses the inclined surface of a measured workpiece and generates deformation, thereby effectively having the sealing function. The connecting device is rapid in connection, good in sealing effect, efficient, and capable of saving cost.
Description
Technical field:
The utility model relates to a kind of connection set.
Background technique
At present common oil hydraulic cylinder or pneumatic cylinder etc. all need to be connected with external air source or hydraulic power by inipple, to carry out air pressure or the work of hydraulic pressure class or experiment, connect rear in order to guarantee sealing effect, generally all adopt workpiece thread bottom O shape circle to seal, operational sequence is that the tubing joint that O shape circle is housed is put into the workpiece thread bottom, being screwed into gland nut compresses joint again, thereby end O shape circle is effectively contacted with the Work piece sealing face play seal action, but the operation that is screwed into nut is more loaded down with trivial details: the double thread mouth, screw in the effective thread part, tighten again, process is more, if need to produce in enormous quantities and need this work, meeting much time power, inefficiency.
The model utility content
The utility model technical issues that need to address provide a kind of connection set and to reach source of the gas or hydraulic power are connected fast with cylinder or oil hydraulic cylinder, can guarantee sealing effect simultaneously.
In order to solve the problems of the technologies described above, the technical solution of the utility model is, a kind of connection set comprises resilient sleeve, tubing head, described tubing head is socketed with connecting head outward, described tubing head passes resilient sleeve, is provided with holddown spring between described tubing head and the resilient sleeve, is provided with guide finger between described connecting head and the resilient sleeve, be provided with contraction spring between described connecting head and the guide finger, described tubing head is provided with seal ring.
Described tubing head is provided with the first annular projection and the second annular projection, described the first annular projection is arranged in the resilient sleeve, the second annular projection is arranged on outside the resilient sleeve, described the second annular projection is provided with seal ring, and described holddown spring is arranged between the first annular projection and the resilient sleeve.
Described seal ring is O-ring seals.
The external diameter that described the first annular projects into the tubing head between the second annular projection reduces gradually.
The utility model compared with prior art tubing head is socketed with connecting head outward, described tubing head passes resilient sleeve, be provided with holddown spring between described tubing head and the resilient sleeve, be provided with guide finger between described connecting head and the resilient sleeve, be provided with contraction spring between described connecting head and the guide finger, described tubing head is provided with seal ring, and the inclined-plane of seal ring automatic impaction measured workpiece also produces distortion, can effectively play seal action.Connect fast good sealing effect, the high cost of saving of efficient.
Description of drawings
Fig. 1 is the utility model structural representation;
1, tubing head; 2, seal ring; 3, connecting head; 4, contraction spring; 5, guide finger; 6, resilient sleeve; 7, holddown spring.
Embodiment
A kind of connection set, comprise resilient sleeve 6, tubing head 1, the described tubing head 1 outer connecting head 3 that is socketed with, described tubing head 1 passes resilient sleeve 6, is provided with holddown spring 7 between described tubing head 1 and the resilient sleeve 6, is provided with guide finger 5 between described connecting head 3 and the resilient sleeve 6, be provided with contraction spring 4 between described connecting head 3 and the guide finger 5, described tubing head 1 is provided with seal ring 2.
Described tubing head 1 is provided with the first annular projection and the second annular projection, described the first annular projection is arranged in the resilient sleeve 6, the second annular projection is arranged on outside the resilient sleeve, described the second annular projection is provided with seal ring, and described holddown spring 7 is arranged between the first annular projection and the resilient sleeve 6.
Described seal ring 2 is O-ring seals.
The external diameter that described the first annular projects into the tubing head 1 between the second annular projection reduces gradually.
Described connecting head 3 is socketed between first annular projection and the second annular projection of tubing head 1, under the effect of guide finger and contraction spring, connecting head 3 is mobile between the first annular projection and the second annular projection, and the external diameter of connecting head 3 changes along with the variation of tubing head 1 external diameter.
When connecting head 3 needs to connect, to resilient sleeve 6 interior compressions, tubing head is at holddown spring 7 with tubing head 1, and effect is lower shrinks in resilient sleeve, connecting head dwindles connecting head 3 outer dias under the effect of guide finger 5, holddown spring 4, and seal ring 2 and connecting head 3 is close; After finishing above operation, this connecting head is directly put into the internal screw workpiece that is connected, then operator grasps resilient sleeve 6 is near workpiece internal thread exterior edge face, guarantee that resilient sleeve 6 do not do significant movement in the operation of back, unclamp tubing head 1, under the effect of spring 7, tubing head 1 is mobile outside resilient sleeve under the effect of Compress Spring, connecting head 3 external diameters enlarge, fix until buckle into the internal thread of workpiece, this moment, spring 7 still for reaching free state, continued connecting head 3 and tubing head 1, thereby reach the seal ring 2 that compresses tubing head 1 end, thereby realize the effect of fast assembling and sealing;
After the testing of workpiece is finished, one of operator holds resilient sleeve 6, the another hand with tubing head 1 to resilient sleeve 6 interior compressions, tubing head is at holddown spring 7, effect is lower shrinks in resilient sleeve, connecting head dwindles connecting head 3 outer dias, operator's fech connection head under the effect of guide finger 5, holddown spring 4.
Connection procedure is convenient and swift, and the inclined-plane of the seal ring 2 automatic impaction measured workpieces of end also produces distortion, can effectively play seal action.Connect fast good sealing effect, the high cost of saving of efficient.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the concrete realization of the utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or without improving design of the present utility model and technological scheme are directly applied to other occasions, all in protection domain of the present utility model.
