Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
Referring to fig. 1 to 4, the present utility model provides a technical solution: rubber joint, including first joint 1, second joint 2 and dabber 3, first joint 1 is corresponding with second joint 2, and dabber 3 is located the axle center portion of first joint 1 and second joint 2, and first joint 1 and second joint 2 all include overcoat 4 and inner core 5, have installed rubber piece 6 between overcoat 4 and the inner core 5, and rubber piece 6 slope is fixed in between overcoat 4 and the inner core 5, and the inner wall of inner core 5 has seted up screw thread draw-in groove 10, and screw thread piece 13 has been installed to the week side of dabber 3, and screw thread piece 13 corresponds with screw thread draw-in groove 10.
In this embodiment, the lower side of the first joint 1 is provided with a groove 7, the upper side of the second joint 2 is fixed with a bump 8, the bump 8 corresponds to the groove 7, and the bump 8 is inserted into the groove 7, so that the first joint 1 and the second joint 2 are combined together.
The clamp plate 12 has been installed to first joint 1 upside, clamp plate 12 is annular structure, the one end of dabber 3 is located clamp plate 12, backing plate 11 has been installed to second joint 2 downside, backing plate 11 is annular structure, and the other end of dabber 3 is located backing plate 11, the mounting groove has been seted up to the upside of backing plate 11, the mounting groove corresponds with second joint 2, insert in recess 7 lug 8, insert in the mounting groove second joint 2, insert the dabber 3 in the axial core of first joint 1 and second joint 2, can be with first joint 1, second joint 2, backing plate 11, clamp plate 12 and dabber 3 make up the installation and form a whole, can use the rubber joint.
