Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is embodiment's of the present utility model structural representation;
Fig. 2 is the structural representation of embodiment of the present utility model when extracting bearing pin.
Among the figure, 1 is pedestal, and 2 is bearing pin, and 21 is draw-in groove, and 3 is fixed base, and 4 is stationary axle, and 5 is clamp, and 51 is an end of clamp, and 52 is the other end of clamp.
Embodiment
Below with reference to drawings and Examples the utility model is done concrete explaination.
But the device of a kind of quick lock in bearing pin of embodiment of the present utility model as shown in Figure 1 comprises pedestal 1 and bearing pin 2.Pedestal 1 is provided with the pin-and-hole (not shown), and bearing pin 2 inserts in the pin-and-hole.Bearing pin 2 is connected with pedestal and is connected by pin-and-hole.
Wherein, also comprise fixed base 3, stationary axle 4 and clamp 5.Fixed base 3 is connected with pedestal 1, and stationary axle 4 is located on the fixed base 3, and clamp 5 is connected with stationary axle 4 and can be around stationary axle 4 rotations.The non-insertion end of not inserting on the bearing pin 2 in the pin-and-hole is provided with draw-in groove 21.When locking during bearing pin 2, an end 51 and the draw-in groove 21 of clamp 5 forms at least that a point contacts also can be in draw-in groove 21 interior rotations; The other end 52 of clamp 5 contacts with pedestal 1.One end 51 of clamp 5 is positioned at the side of the face vertical with horizontal plane at the running shaft place of described clamp 5, and the other end 51 and the center of gravity of clamp 5 is positioned at the opposite side of the face vertical with horizontal plane at the running shaft place of described clamp 5.
Thus, under the effect of center of gravity, clamp 5 can rotate also until the other end 52 places on the pedestal 1; And an end 51 of clamp 5 forms at least a point with the draw-in groove 21 of bearing pin 2 and contacts, and so under the effect of pedestal 1 restriction clamp 5 rotations, can limit bearing pin 2 and upwards come off.Simultaneously can and bearing pin 2 between the clamp 5 that freely rotates, can rotate easily the space again, so that quick insertion or taking-up bearing pin 2.The utility model is controlled well, easy to operate, cost is low, non-maintaining, and safe and reliable, using scope Chang Guang.
In the utility model, the end 51 that the draw-in groove 21 in the bearing pin 2 needs only when clamp 5 can freely rotate therein, and forms at least one some contact, when bearing pin 2 comes off pin-and-hole, it is applied resistance get final product, its shape can be for multiple, and the present embodiment is not restricted this.
In embodiment of the present utility model, preferably be fixedly connected with between fixed base 3 and the pedestal 1.Certainly, also can be and removably connect, so that adapt to the bearing pin of different model size.
In embodiment of the present utility model, stationary axle 4 is vertical with clamp 5, and preferred stationary axle 4 is parallel with pedestal 1, and namely the running shaft of clamp 5 is parallel with pedestal 1.When bearing pin 2 is deviate from, rotation clamp 5 will be more laborsaving, have higher efficient.
As shown in fig. 1, in embodiment of the present utility model, draw-in groove 21 be shaped as circular groove.And an end 51 of preferred clamp 5 be shaped as arc-shaped convex.And an end 51 of preferred clamp 5 be shaped as cam-shaped.The shape matching of circular groove and projection is suitable for rotation between groove and the projection, less friction between relatively.
In addition, as shown in fig. 1, in embodiment of the present utility model, an end 51 of clamp 5 and the distance of the distance of stationary axle 4 less than pedestal 1 and stationary axle 4.When bearing pin 2 inserted and take out, the short so that end 51 of clamp 5 of distance can rotate to the space of stationary axle 4 belows, for the movement of bearing pin 2 is provided convenience.
In addition, in embodiment of the present utility model, also can be provided with the pushing part on the clamp 5, facilitate for promoting clamp 5 rotations.
In the embodiment of model utility in actual use, as shown in fig. 1, under static state, clamp 5 utilizes the deadweight rotation until the other end 52 places on the pedestal 1; When inserting bearing pin 2, the bottom of bearing pin 2 promotes an end 51 rotations of clamp 5 until in the bearing pin 2 insertion pin-and-holes, clamp 5 is because center of gravity effect rotation subsequently, until the other end 52 places on the pedestal 1 again, at this moment, an end 51 of clamp 5 places in the draw-in groove 21 of bearing pin 2, because the restriction of 1 pair of the other end 52 of pedestal, clamp 5 can not rotate, so an end 51 of clamp 5 limits draw-in groove 21 and move up, and fixes bearing pin 2.
When need took out bearing pin 2, as shown in Figure 2, direction was used external force rotation clamp 5 as shown by arrows in FIG., because an end 51 of clamp 5 can rotate in draw-in groove 21, an end 51 rotates draw-in groove 21, and bearing pin 2 can detach pedestal 1 thus.
The cut to bearing pin of usefulness of the transportation that the utility model can be widely used in all trades and professions logistics vehicles such as the engineering machinery such as crawler crane, trailer, factory's vehicle transport machinery, highway transport vehicle, railway station transport vehicle are defeated, port traffic vehicle, connections of airport freight transportation vehicle, supermarket vehicle.
Above specific embodiment of the utility model is described in detail, but it is as example, the utility model is not restricted to specific embodiment described above.To those skilled in the art, any equivalent modifications that this model utility is carried out and substituting also all among category of the present utility model.Therefore, not breaking away from impartial conversion and the modification of doing under the spirit and scope of the present utility model, all should be encompassed in the scope of the present utility model.
