Abstract
The utility model provides a spherical joint device. The spherical joint device comprises an upper fixing block (3), a lower fixing block (6) and a rolling ball (5). The lower surface of the upper fixing block (3) and the upper surface of the lower fixing block (6) are spherical faces respectively. The upper fixing block (3) and the lower fixing block (6) are fixed above the rolling ball (5) and below the rolling ball (5) respectively. The rolling ball (5) rolls between the upper fixing block (3) and the lower fixing block (6). A plurality of supporting rods can be arranged on the surface of the rolling ball through a welding method or other fixing methods, when pressure is exerted on the supporting rods, the rolling ball can roll between the upper friction face and the lower friction face, and therefore the pressure borne by the supporting rods can be eliminated.
Description
Technical field
The utility model has related to a kind of joint node, particularly a kind of spherical joint device.
Background technology
For thoroughly discharging spherical bearing root rod member moment of flexure, the present invention proposes a kind of articulated type support style, on bearing, connect various rod member for grid, this bearing energy restraint joint displacement, and release nodal moment can full degree of freedom rotate, thus change structure system stress form.
Summary of the invention
Goal of the invention of the present utility model is to solve existing fixing joint node can not eliminate the problem from the additional bending moment of support bar, and a kind of spherical joint device is provided.
In order to complete goal of the invention of the present utility model, the utility model by the following technical solutions:
A kind of spherical joint device of the present utility model, it comprises: upper fixed block, lower fixed block and spin, wherein: the upper soffit of fixed block and the upper surface of lower fixed block are respectively spherical, upper fixed block and lower fixed block are separately fixed at spin above and below, and spin is rolled between upper fixed block and lower fixed block;
A kind of spherical joint device of the present utility model, wherein: fixed piece and lower fixed block are separately fixed at spin above and below by least three screw bolt and nut;
A kind of spherical joint device of the present utility model, wherein: rubbing surface and lower rubbing surface are housed respectively on the upper surface of the soffit of fixed piece and lower fixed block;
A kind of spherical joint device of the present utility model, wherein: described upper frictional layer and lower frictional layer are made up of tetrachloro-ethylene material.
A kind of spherical joint device of the present utility model, wherein: described bolt is four, they are separately fixed on four angles of fixed block and lower fixed block.
Several support bars can be contained on roller surface by mode or other fixing modes of welding, and in the time that support bar is under pressure, spin can be rolled between upper rubbing surface and lower rubbing surface, so just can eliminate the suffered pressure of support bar.
Accompanying drawing explanation
Fig. 1 is the forward generalized section of the utility model spherical joint device;
Fig. 2 is bowing to schematic diagram of the utility model spherical joint device.
In Fig. 1 and Fig. 2, label 1 is bolt; Label 2 is nut; Label 3 is upper fixed block; Label 4 is upper rubbing surface; Label 5 is spin; Label 6 is lower fixed block; Label 7 is lower rubbing surface.
The specific embodiment
As depicted in figs. 1 and 2, spherical joint device of the present utility model comprises: upper fixed block 3, lower fixed block 6 and spin 5, the upper surface of the soffit of upper fixed block 3 and lower fixed block 6 is respectively spherical, and rubbing surface 4 and lower rubbing surface 7 are housed respectively on the upper surface of the soffit of upper fixed block 3 and lower fixed block 6.Upper frictional layer 4 and lower frictional layer 7 are made up of tetrachloro-ethylene material.Upper fixed block 3 and lower fixed block 6 are separately fixed at spin 5 above and belows by four bolts 1 and nut 2.Four bolts 1 and nut 2 are separately fixed on four angles of fixed block 3 and lower fixed block 6.Spin 5 is rolled between upper fixed block 3 and lower fixed block 6.It is upper that several support bars can be contained in spin 5 surfaces by the mode of welding or other fixing modes, and in the time that support bar is under pressure, spin 5 can be rolled between upper rubbing surface 4 and lower rubbing surface 7, so just can eliminate the suffered pressure of support bar.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and without prejudice to spirit of the present utility model in the situation that, the utility model can be done any type of modification.
