Abstract
The utility model provides a novel swivel joint of central authorities, including the solid of revolution, revolving axle with solid of revolution normal running fit, the one end of the solid of revolution is provided with connected to the fence, revolving axle and connected to the fence looks fixed connection, be provided with the dustproof seal structure of combination formula between the other end of the revolving axle and the solid of revolution, the tip of the solid of revolution is provided with the mounting groove, elastomeric composition formula dust sealing spare sets up in the mounting groove, a plurality of slots have been seted up on the terminal surface of elastomeric composition formula dust sealing spare and revolving axle contact, through set up that the slot not only can reduce and the revolving axle between area of contact, reducing abrasion, and can remain when having a small amount of steam to get into and can not infiltrate at the ditch inslot, because it then can in close contact with to have elasticity, thereby have good preventing dust, water -proof effects, and life is longer.
Description
Technical field
This utility model relates to a kind of Novel central swivel coupling, particularly to a kind of Novel central swivel coupling with good dustproof and waterproof effect.
Background technology
Existing Novel central swivel coupling; generally including revolving body and gyroaxis, the junction of revolving body end and gyroaxis would generally arrange sealing gasket and seal, and there will be abrasion after existing sealing gasket life-time service; then causing and there is gap between gyroaxis and revolving body, sealing effectiveness is poor.
Summary of the invention
The purpose of this utility model is in that to overcome the deficiency of above-mentioned technology, thus providing a kind of Novel central swivel coupling, has good dust-proof, waterproof effect.
This utility model be employed technical scheme comprise that such: Novel central swivel coupling, including revolving body, the gyroaxis being rotatably assorted with described revolving body, one end of described revolving body is provided with connection baffle plate, described gyroaxis is fixedly connected with the described baffle plate that is connected, combination type dust-proof sealing structure it is provided with between the other end of described gyroaxis and described revolving body, the end of described revolving body is provided with mounting groove, described elastomeric composition formula dust seal is arranged in described mounting groove, the end face that described elastomeric composition formula dust seal contacts with described gyroaxis offers some grooves.
Improve further: described groove is rectangular.
Improve further: described elastomeric composition formula dust seal includes ringwise elastomer, ringwise sealing member, and described sealing member is sheathed on described elastomer, and described groove is opened on described sealing member.
Improving further: offer some cannelures on described gyroaxis, be provided with rotating seal ring in described cannelure, some described rotating seal rings are along the axial distribution of described gyroaxis.
Improve further: between described connection baffle plate and described revolving body, be provided with described elastomeric composition formula dust seal.
By adopting preceding solution, the beneficial effects of the utility model are: be possible not only to reduce the contact area between gyroaxis by arranging groove, reduce abrasion, and have a small amount of steam can remain in groove when entering and do not penetrate into, then can be in close contact owing to having elasticity, thus have good dust-proof, waterproof effect, and service life is longer.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram;
Fig. 2 is the A place enlarged drawing of Fig. 1.
Wherein: 1, revolving body; 2, gyroaxis; 3, baffle plate is connected; 4, elastomer; 5, sealing member; 6, groove; 7, rotating seal ring.
Detailed description of the invention
This utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Such as Fig. 1, shown in Fig. 2, the open a kind of Novel central swivel coupling of this utility model, including revolving body 1, the gyroaxis 2 being rotatably assorted with described revolving body 1, one end of described revolving body 1 is provided with connection baffle plate 3, described gyroaxis 2 is fixedly connected with the described baffle plate 3 that is connected, it is provided with combination type dust-proof sealing structure between described gyroaxis 2 and the other end of described revolving body 1, the end of described revolving body 1 is provided with mounting groove, described elastomeric composition formula dust seal 5 is arranged in described mounting groove, the end face that described elastomeric composition formula dust seal 5 contacts with described gyroaxis 2 offers some grooves 6, described elastomeric composition formula dust seal 5 includes ringwise elastomer 4, ringwise sealing member 5, described sealing member 5 is sheathed on described elastomer 4, described groove 6 is opened on described sealing member 5.
Operation principle: elastomer 4 provides and sealing member 5 and gyroaxis 2 are in close contact, the groove 6 arranged on sealing member 5 can not only reduce the contact area between itself and gyroaxis 2, reduce abrasion, and have a small amount of steam can remain in groove 6 when entering and do not penetrate into, thus have good dust-proof, waterproof effect, and service life is longer.
The embodiment optimized in the present embodiment is that described groove 6 is rectangular.
Described gyroaxis 2 offers some cannelures, rotating seal ring 7 it is provided with in described cannelure, some described rotating seal rings 7 are along the axial distribution of described gyroaxis 2, the rotating seal ring 7 being generally arranged on revolving body 1 is arranged on gyroaxis 2, it is re-established as piston rod packing form by original piston seal form, owing to rotating seal ring 7 is arranged on revolving body 1, revolving body 1 is when die sinking, mold-opening structure is complicated, add die sinking cost, and directly rotating seal ring 7 is arranged on gyroaxis 2, the mode directly gyroaxis 2 can being processed carries out, in addition compact overall structure, good sealing effect.
In order to improve sealing effectiveness further, between described connection baffle plate 3 and described revolving body 1, it is provided with described elastomeric composition formula dust seal.
Of the present utility model ultimate principle and principal character and advantage thereof have more than been shown and described; skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and explanation is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications; these changes and improvements both fall within the scope of claimed this utility model, and this utility model claims scope and defined by appending claims and equivalent thereof.
