Rotary joint structure described in the utility model is connected between oil cylinder and the control oil channel, it is simple in structure, cost is lower, be implemented under the situation of oil cylinder rotation, control oil channel keeps motionless and not influenced by torsional interaction, effectively solves being connected because of oil cylinder rotates between oil cylinder and the control oil channel problem that the control oil channel connecting tube is forced to torsional deformation to occur.
Description of drawings
Fig. 1 is the mounting structure schematic representation of rotary joint structure described in the utility model.
Fig. 2 is the mounting structure schematic representation of another mode of execution of rotary joint structure described in the utility model.
Below come the utility model is further described by the drawings and specific embodiments:
Embodiment
As shown in Figure 1, rotary joint structure described in the utility model is connected between oil cylinder 1 and the control oil channel 2, it comprise be tightly connected and in relative rotation oil cylinder take over 3 and control oil channel joint tube 4; Described control oil channel joint tube 4 connects with control oil channel 2 and is tightly connected; Described oil cylinder is taken over 3 and is connected with oil cylinder 1 rigid seal and is provided with the adapter oil circuit that communicates with oil cylinder 1 inner chamber in it, described adapter oil circuit 31 is provided with the oil transportation hole 32 that connects with control oil channel joint tube 4, described oil transportation hole 32 can be for a plurality of, and it is evenly distributed on oil cylinder and takes over 3 perisporium.
Further, the head of described oil cylinder adapter 3 stretches in the control oil channel joint tube 4, and it is installed in the control oil channel joint tube 4 by bearing pack 5.Above-mentioned oil cylinder is taken over 3 the axis and the axis normal setting of control oil channel joint tube 4, and promptly oil cylinder takes over 3 and the 4 vertical settings of control oil channel joint tube, and right-angle turning is connected conserve space between realization oil cylinder 1 and the control oil channel 2.As shown in Figure 2, the axis of above-mentioned oil cylinder adapter 3 and the axis of control oil channel joint tube 4 also can be arranged in parallel, but because control oil channel 2 generally all is arranged on the bottoms of oil cylinder 1, it needs additional straight angle joint 7 to realize connecting, and it is relatively large to take up room.Therefore, rotary joint structure shown in Figure 1 is an optimum implementation.
