Abstract
The utility model provides a quick joint which is tightly connected with a tool and comprises a joint main body. The joint main body is provided with a joint hole. A ball hole is arranged on the wall of the joint hole. A ball used for clamping the connecting rod of the tool is arranged in the ball hole. A rotatable locking operation sleeve is sheathed outside the joint main body. The inner wall of the locking operation sleeve is provided with an inclined surface or arc surface which can squeeze the ball to enable the ball to protrude the wall of the joint hole and to tightly clamp the connecting rod of the tool. By adopting the technical scheme, when compared with a traditional quick joint, the utility model has the advantages that the structure of the quick joint is simpler; and since the quick joint is in clamping fit with the connecting rod of the tool, the connecting rod of the tool is prevented from getting loose on the quick joint and the tool connected on the quick joint can work accurately and stably.
Description
Technical field
The utility model relates to the hydraulic quick coupler technical field.
Background technology
Hydraulic quick coupler is to link to each other with lathe or pistol electric drill to be used for the device of presto tool, and described instrument can be drill bit, screwdriver etc.Present hydraulic quick coupler utilizes operating sleeve in axial sliding to promote to be arranged on ball in the adapter body, makes it expose ball hole in the adapter body, snaps in the groove in the instrument extension bar, finishes being connected of hydraulic quick coupler and instrument.The hydraulic quick coupler of this structure does not have clamping relation between ball and the instrument extension bar and just is stuck in the described groove, makes to have the axial gap of rocking between instrument and hydraulic quick coupler, be unfavorable for instrument accurately and steady operation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of hydraulic quick coupler closely that is connected with instrument.For this reason, the utility model is by the following technical solutions: it comprises adapter body, described adapter body has nipple orifice, the joint hole wall is provided with ball hole, be provided with the ball that is used for the clamping tool extension bar in the ball hole, described adapter body is with rotatable locking operation cover outward, and the inwall of described locking operation cover has and can push ball and make it protrude in the joint hole wall and the inclined-plane or the cambered surface of clamping tool extension bar.Be used to adopt the technical solution of the utility model, the hydraulic quick coupler that structure of the present utility model is more traditional is simpler, and make and be clamping engagement between hydraulic quick coupler and the instrument extension bar, can prevent instrument extension bar loosening on hydraulic quick coupler, make the instrument that is connected on the hydraulic quick coupler can be accurately and steady operation.

The specific embodiment
Embodiment 1, with reference to accompanying drawing 1,2.
The utility model comprises adapter body 1, described adapter body has nipple orifice 2, the joint hole wall is provided with ball hole 3, be provided with the ball 4 that is used for the clamping tool extension bar in the ball hole, described adapter body is with rotatable locking operation cover 5 outward, the inwall of described locking operation cover has and can push ball and make it protrude in the joint hole wall and the inclined-plane or the cambered surface of clamping tool extension bar, in the present embodiment, what the inwall extruding ball of locking operation cover 5 made that it protrudes in main body cover inwall is cambered surface 6, described cambered surface 6 for described locking operation cover inwall along circumferential set corresponding with the ball hole cambered surface of gradually opening shape that is.Described extruding ball can be directly to push or indirect extrusion, with regard to the former, the diameter of ball should be greater than the nipple orifice wall thickness that the ball hole place is set, the interior wall energy squeezing roll pearl clamping tool extension bar of locking operation cover 5, with regard to the latter, middlewares such as extension bar can be set before ball, and described cambered surface or inclined-plane be the extruding middleware earlier, and middleware passes to ball with extruding force.
In use, after the instrument extension bar inserted nipple orifice, as shown in Figure 2, the locking operation that turns clockwise cover 5 made ball 4 be pushed by the shape cambered surface 6 of gradually opening that diameter reduces gradually, and the instrument extension bar clamps and can not become flexible the most at last.When the need removal tool, be rotated counterclockwise locking operation cover 5, make the bigger corresponding ball hole of a side of close diameter of gradually opening shape cambered surface 6, thereby loosen the clamping of ball, thereby can take off instrument from hydraulic quick coupler to the instrument extension bar.
The utility model comprises adapter body 210, described adapter body has nipple orifice 220, the joint hole wall is provided with ball hole 230, be provided with the ball 240 that is used for the clamping tool extension bar in the ball hole, described adapter body is with rotatable locking operation cover 250 outward, the inwall of described locking operation cover has and can push ball and make it protrude in the joint hole wall and the inclined-plane or the cambered surface of clamping tool extension bar, in the present embodiment, described inclined-plane or cambered surface are meant the taper surface 260 corresponding with ball hole that locking operation cover inwall has, and described locking operation cover 250 is threaded with adapter body 210.Described extruding ball can be directly to push or indirect extrusion, with regard to the former, the diameter of ball should be greater than the main body sleeve wall thickness that the ball hole place is set, the interior wall energy squeezing roll pearl clamping tool extension bar of locking operation cover 250, with regard to the latter, middlewares such as extension bar can be set before ball, and described cambered surface or inclined-plane be the extruding middleware earlier, and middleware passes to ball with extruding force.
In use, after the instrument extension bar inserted nipple orifice, shown in Fig. 3,4, rotational lock operating sleeve 250 made its upwards also i.e. motion of right side in figure, the taper surface 260 that makes ball 240 diameters reduce gradually pushes, and the instrument extension bar clamps and can not become flexible the most at last.When the need removal tool, opposite spin locking operation cover 250 makes its also i.e. motion of left side in figure downwards, makes the bigger corresponding ball hole of a side of diameter of taper surface 260, thereby loosen the clamping of ball, thereby can take off instrument from hydraulic quick coupler to the instrument extension bar.
