Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
A kind of swivel joint as shown in Fig. 1-Fig. 7, including swivel joint body 2 and the bolt 1 that is installed through in swivel joint body 2.
As shown in figures 3 to 6, described swivel joint body 2 includes the rotatable head 21 being sequentially connected, rotates main body 22 and conduit connection 23.Described rotatable head 21 offers bolt and installs cavity 24.Described rotation main body 22 is provided with the first cavity 25.Described conduit connection 23 is provided with the second cavity 26.Described bolt is installed and is interconnected between cavity the 24, first cavity 25 and the second cavity 26.Described conduit connection 23 uses ring joint.Described rotation main body 21 is provided with clip 5.Cavity installed by described bolt, on the one hand is used for making bolt-through installed therein, on the other hand with the first cavity, the second cavity, the 3rd cavity together as gas or the circulation passage of oil body.Described ring joint, for connecting trachea or the oil pipe of passenger vehicle, ring joint can increase the frictional force between swivel joint and trachea or oil pipe, it is ensured that the firm connection on swivel joint of trachea or oil pipe.After trachea or oil pipe being socketed in outside ring joint, then use clip to be wraps closely about the periphery of trachea or oil pipe, be further ensured that the fastness that trachea or oil pipe are connected with swivel joint.
As it is shown in fig. 7, described bolt 1 includes bolt head 11 and with externally threaded screw rod 12.Described screw rod 12 is installed cavity 24 from bolt and is passed, and its partial threads connection stretching out bolt installation cavity has nut 3.Described screw rod 11 is provided with the 3rd cavity 13, and the 3rd cavity 13 outer wall is provided with the through hole 14 being connected with the 3rd cavity.Described 3rd cavity 13 is installed cavity 24 by through hole 14 with bolt and is connected.A seal washer 4 it is respectively equipped with between described bolt head 11 and rotatable head 21 and between rotatable head 21 and nut 3.Described through hole, is used for making to be formed between the 3rd cavity and the first cavity, the second cavity path, it is ensured that passenger vehicle trachea or the circulation of oil pipe medium.Described through hole is positioned at bolt and installs in cavity.Described seal washer, for ensureing the sealing of swivel joint internal duct, prevents fluid from oozing out.Described nut, for bolt and swivel joint body being linked together, makes the two that relative motion no longer to occur after regulating relative position.
Assembling of the present utility model and use process be:
First, the screw rod of bolt is installed cavity from bolt and passes, and place a seal washer respectively on the screw rod that cavity both sides installed by bolt.Then, rotate swivel joint body, make swivel joint body turn an angle for rotary shaft with screw rod, when swivel joint body towards after meeting the connection request of current pipeline, fastening nut, makes swivel joint body and is bolted together, and swivel joint body and bolt are not occurring relative motion.Then, from bolt, screw rod is installed the partial threads stretched out cavity to be connected on the pipe interface of clutch general pump, clutch slave cylinder or other valve class devices；Now, between nut and pipe interface, it is coated with fluid sealant, to ensure the sealing effectiveness that swivel joint is connected with pipe interface.Finally, current pipeline is enclosed within the outside of ring joint, and with clip, current pipeline is close-coupled on ring joint.When need change swivel joint body towards time, unscrew nut, make swivel joint body turn to suitable position with screw rod for rotary shaft, the most again by nut screwing clamping.
Embodiment described above is only to be described preferred implementation of the present utility model; not scope of the present utility model is defined; on the premise of without departing from this utility model design spirit; various deformation that the technical solution of the utility model is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that this utility model claims determine.
