Abstract
The utility model discloses a rotary joint rotates unit, first terminal, second terminal, kicking block and spring that the unit includes swinging head, fixed axle, is arranged in the swinging head rotate, fixed axis rotation is consolidated for this to the swinging head. Work a telephone switchboard respectively through first terminal and second terminal, just make the second terminal rotation relatively of first terminal through rotating the unit. Like this when a terminal connection pivoted connecting wire, and during the fixed connecting wire of the 2nd terminal connection, holistic connection still can remain stable and can not hinder the rotation action that needs the pivoted connecting wire.
Description
Technical field
The utility model relates to the transition connecting apparatus between a kind of connecting line and connecting line.
Background technology
Vehicle-mounted, shipborne radar mainly comprises star-pursuing device and receiver at present, and other accessories.Because car, ship are in motion process and satellite running in orbit, star-pursuing device is made to need constantly to adopt multivariant rotation to adjust angle and corresponding satellite all the time.And in the process of rotating, the connecting line between star-pursuing device and receiver also can rotate along with the rotation of star-pursuing device; And receiver is fixed, therefore stable connection is the problem needing to solve how to make the connecting line between receiver and star-pursuing device still remain in a dynamic state.
Therefore, need a kind of new technical scheme to solve the problem.
Utility model content
The purpose of this utility model is the deficiency existed for prior art, provides a kind of rotary joint, and this rotary joint, as the transition element of connecting line, can make the connection between star-pursuing device and receiver use and keep stable connection.
For achieving the above object, the utility model can adopt following technical scheme:
A kind of rotary joint, the first binding post of the rotating unit front end that comprises shell, is positioned at the rotating unit of shell, is resisted against, is fixed on the second binding post of rotating unit rear end; Described rotating unit comprises rotation pipe, fixed axis, is arranged in the jacking block and spring that rotate pipe; Described first binding post is provided with the contact pin inserting and rotate in pipe; The front end of described rotation pipe is provided with accommodates and fixes the jack of this contact pin; Rotate the rear end of pipe and be provided with the opening inserted the front end for fixed axis; And jacking block be resisted against the front end of this fixed axis and jacking block between spring and fixed axis; One end of spring is resisted against jacking block and the other end is resisted against rotation pipe inside; Described rotation pipe rotates relative to this fixed axis; The front end of described second binding post is provided with inserts and the inserted block be fixed in fixed axis.
Compared with prior art, the utility model rotary joint by the first binding post and the wiring respectively of the second binding post, and enables the first binding post rotate relative to the second binding post by rotating unit.Like this when the connecting line of the first binding post connection of rotating, and during connecting line that the second binding post is connected and fixed, overall connection still can keep stable and the rotational action of the connecting line that needs can not be hindered to rotate.
Accompanying drawing explanation
Fig. 1 is the generalized section of the utility model rotary joint.
Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
Refer to Fig. 1, the utility model discloses a kind of rotary joint, the first binding post 3 of rotating unit 2 front end that comprises shell 1, is positioned at the rotating unit 2 of shell 1, is resisted against, is fixed on the second binding post 4 of rotating unit 2 rear end.Wherein be electrically connected to keep, described first binding post 3, second binding post 4, rotating unit 2 are all metal materials.Described rotating unit 2 comprises rotation pipe 21, fixed axis 22, is arranged in the jacking block 23 and spring 24 that rotate pipe 21.Described first binding post 3 is provided with the contact pin 31 inserting and rotate in pipe 21; The front end of described rotation pipe 21 is provided with accommodates and fixes the jack 22 of this contact pin 31.Rotate the rear end of pipe 21 and be provided with the opening inserted the front end for fixed axis 22; And jacking block 23 be resisted against the front end of this fixed axis 22 and jacking block 23 between spring 24 and fixed axis 22.One end of spring 24 is resisted against jacking block 23 and the other end is resisted against rotation pipe 21 inside.Rotate pipe 21 to rotate relative to fixed axis 22, and jacking block 23 and fixed axis 22 against keeping the stable of rotating unit 2 entirety, wherein the effect of spring 24 to cushion the pressure dependence between jacking block 23 and fixed axis 22, because when the pressure dependence in the environment that jolts that be in vehicle-mounted, boat-carrying between jacking block 23 and fixed axis 22 changes at any time, if pressure is excessive, excessive resistance can be caused to the rotation of rotating pipe 21, and the buffering of spring 24 can address this problem.Described rotation pipe 21 rotates relative to this fixed axis 22; The front end of described second binding post 4 is provided with inserts and the inserted block 41 be fixed in fixed axis 22.
Further, processing to make part and the convenience of assembling, being provided with further in described shell 1 and being fixed on sleeve 5 in shell 1 and gland 6.The rear end of described rotating unit 2 and the first binding post 3 is all housed in the cavity of sleeve 5, and the outer surface of the first binding post 3 is fitted with the inner surface of sleeve 5 and contacted.The outside of described sleeve 5 is provided with stage portion 51, and sleeve 5 is housed in cavity that gland 6 has and the rear end of gland 6 is resisted against in described stage portion 51; The outer surface of gland 6 contacts with the inner surface of shell 1 and fixes.Like this, first sleeve 5 load shell 1 interior after, then gland 6 is pressed into until with stage portion 51 against, gland is squeezed between sleeve 5 and shell 1.And the outside of gland 6 is provided with outer extensions 61 and is resisted against shell 1 front end, make assembling procedure simple like this and good positioning relation and mutual fixing between sleeve 5, gland 6 and shell 1, can be formed.Described second binding post 4 extends shell 1 and the second binding post 4 is fixed on shell 1, and this second binding post 4 can connect the connecting line not needing the moment to rotate, as connected the connecting line of the receiver of vehicle-mounted, shipborne radar; And the first binding post 3 is owing to can rotate relative to the second binding post 4, so the connecting line that needs rotate can be connected, as connected the connecting line of the star-pursuing device needing the moment to rotate of vehicle-mounted, shipborne radar.So namely, the connecting line between receiver and star-pursuing device can be made still to remain stable connection in a dynamic state in guarantee.And in order to more facilitate wiring, the front end of described first binding post 3 is provided with fluting 32, and projection 33 is extended in the side of the first binding post 3.Can make the both direction of the first binding post 3 all can wiring and increase the versatility of wiring like this.
