An embedded hole is formed at the bottom of the movable plate and is sleeved on the central column, and a plurality of corresponding screw holes are pierced around the embedded hole. The perforation is provided with a plurality of bolts passing through each perforation and screwed to each screw hole, and an upper joint structure is extended upward on the top of the movable plate.

Further, the utility model is provided with a circular embedding groove at the position corresponding to the central column on the installation surface. The central column is a circular cylinder and is embedded in the embedding hole with the bottom. The hole is a circular groove and is nested on the top of the center column. A straight rod is set upward on the top of the movable disc, and the top ring is formed on the top of the straight rod.

Preferably, eight screw holes are provided at equal intervals on the installation surface, eight through holes are provided, and eight bolts are provided.

Preferably, the upper coupling structure includes a straight rod extending from the top surface of the movable plate and a top ring formed on the outer end of the straight rod, and the lower coupling structure is an annular bottom ring.

Preferably, the upper coupling structure includes a straight rod extending from the top surface of the movable disc and a ㄩ-shaped block formed on the outer end of the straight rod, and a positioning hole is pierced at the opposite part of the ㄩ-shaped block.

When adjusting the joint angle of the utility model, each bolt is disassembled in advance, and then the movable plate is rotated to the required position, and then each bolt is screw-locked in each perforation and each screw hole, thereby positioning the position of the joint, because the utility model can The angle of the upper joint structure relative to the lower joint structure is adjusted, so it can be suitable for installation on various types of locomotives, and has an excellent general-purpose effect.

Detailed ways

The utility model is a steerable shock absorber, as shown in the first preferred embodiment of Fig. 1 to Fig. 3, the shock absorber includes a press cylinder body 10, a movable joint inserted and combined with the bottom of the press cylinder body 10 Rod 20, a spring 30 combined between the cylinder body 10 and the movable rod 20, and a joint 40 coupled to the top of the cylinder body 10, wherein:

The cylinder body 10 is provided with a first cylinder body 11, the first cylinder body 11 is a circular cylinder body arranged vertically and protrudes outwards on the peripheral side to form a spring flange 12 on the ring, and the first cylinder body 11 A circular mounting surface 13 is formed on the top, a circular socket 14 is formed in the center of the mounting surface 13, and a central column 15 is embedded in the socket 14. The central column 15 is a circular cylinder and is embedded with a bottom end. Located in the embedding groove 14, eight screw holes 16 are arranged at equal intervals in a circular manner on the installation surface 13 around the center column 15, extending outward on the top side of the first cylinder body 11 peripheral surface and Combined with a second cylinder block 17 .

The movable rod 20 is provided with a rod portion 21 extending axially along the first cylinder body 11. The top section of the rod portion 21 is inserted in the bottom of the first cylinder body 11 and can move forward and backward in the axial direction. The peripheral surface of the bottom section is corresponding to the upper spring flange 12 to protrude to form a ring lower spring flange 22, which forms a ring at the bottom end of the rod portion 21 and serves as a bottom ring 23 of the lower joint structure.

The spring 30 is vertically disposed and sheathed on the bottom of the first cylinder body 11 and the top section of the rod 21 . The top and bottom edges of the spring 30 abut against the upper spring flange 12 and the lower spring flange 22 respectively.

Joint 40 is provided with a movable disc 41, and the shape of movable disc 41 matches the circular disc body of installation surface 13 and forms a circular embedding hole 42 in the center of the bottom surface. The bottom surface of 41 leans against the installation surface 13, and the movable plate 41 is provided with eight perforations 43 corresponding to each screw hole 16 around the embedded hole 42, and eight bolts 44 are respectively threaded through each perforation 43 and then screwed to each screw hole 16. Thus, the joint 40 is combined with the top of the first cylinder body 11, and a straight rod 45 is extended upward in the center of the top surface of the movable plate 41, and a circular top ring 46 is formed at the top of the straight rod 45. Thus, The straight rod 45 and the top ring 46 are used as the upper joint structure.

When the utility model is used, the top ring 46 and the bottom ring 23 are combined on the rear side of the locomotive. When the position of the joint 40 is to be adjusted, as shown in Figures 3 to 5, the bolt 44 is disassembled and then the joint 40 is rotated. Since the movable plate 41 is sleeved on the central column 15 by using the embedded hole 42, it can freely rotate and move with the embedded hole 42 as the center point. When the top ring 46 is adjusted to the required angular position, align the through holes 43 with the screw holes 16 and screw-lock each bolt 44 to position the joint 40 together. Thus, the utility model can adjust the top ring 46 to a variety of different angles relative to the bottom ring 23, thus being suitable for installation at different angles. The locomotive is convenient for users to use.

The joint of the present utility model has other embodiments, such as the second preferred embodiment shown in FIG. 6 , which changes the shape of the joint structure on the joint.

The joint 40A of the second preferred embodiment forms a ㄩ-shaped block 46A on the top of the straight rod 45, and a round hole-shaped positioning hole 461A is relatively pierced on the ㄩ-shaped block 46A. 45 and ㄩ-shaped block 46A are used as upper joint structures of different forms. And since the rest of the second preferred embodiment is the same as the first preferred embodiment, it will not be repeated here.
