[0023] Reference Figs. 1-3 A simple adjustable support device, the support device is mainly composed of upper support 1, connecting seat 2, support cylinder 3, support rod 4, adjusting nut 5, lower support 6 and connecting piece.

[0024] The upper support 1 and the lower support 6 are the installation basis of the support device, when the supported part moves relatively, the connecting seat 2 and the support rod 4 rotate around the upper support 1 and the lower support 6 respectively, and at the same time, the support rod 4 slides in the support cylinder 3 until the support cylinder 3 contacts with the adjusting nut 5, the supported part moves to the designated position and is reliably supported.

[0025] The upper support 1 and the lower support 6 are the installation basis of the support device, and are respectively assembled on the installation surfaces of the two supported parts. The upper support 1 and the lower support 6 are symmetrical parts, each having two lugs. When installing, the central surface of the two supports should be overlapped as the installation reference surface, and the installation angle can be adjusted according to the actual installation space.

[0026] The connecting seat 2 and the support rod 4 are respectively installed in the inner side of the lug of the upper support 1 and the lower support 6 through the pin shaft, and are limited by the split pin, so that they can only rotate on the pin shaft of the upper support and the lower support.

[0027] One end of the connecting seat 2 is a lug, and the other end is a shaft segment. The connecting seat 2 connects the upper support 1 and the support cylinder 3 respectively, so as to ensure that the support cylinder 3 can rotate around the upper support 1.

[0028] One end of the support cylinder 3 is welded with the connecting seat 2. The support cylinder 3 is a hollow structure, and the inner ring is polished and coated with lubricating grease during assembly, so as to ensure that the support rod 4 can move smoothly in the support cylinder 4.

[0029] One end of the support rod 4 is a ball head, so as to reduce the friction with the support cylinder and be guided by the inside of the support cylinder. The other end of the support rod 4 is a lug, which can rotate around the lower support after assembly. The lug of the support rod 4 is provided with a threaded segment above the lug, which is used for adjusting the position of the adjusting nut 5. The length of the threaded segment can be adjusted according to actual needs.

[0030] The adjusting nut 5 is a double nut for use. The adjusting nut 5 is installed on the threaded segment of the support rod, and the position of the adjusting nut 5 on the threaded segment of the support rod is adjusted according to actual needs. After the adjustment is completed, the double nuts are tightened to eliminate the gap between the threads, so as to ensure that the support cylinder can be reliably supported at any designated position.

The upper support 1 and the lower support 6 are respectively fixed on the mounting surfaces of two supported members. The connecting seat 2 is connected with the upper support 1 by a lug and is integrally welded with the support cylinder 3 at the other end, so as to drive the support cylinder 3 to rotate around the upper support 1. The support cylinder 3 is a hollow structure, which can ensure the smooth movement of the support rod 4 inside. The support rod 4 is provided with a ball head at one end to reduce the friction with the inside of the support cylinder 3, and is provided with a lug at the other end to be connected with the lower support 6, so as to ensure that the support rod 4 can rotate around the lower support 6. The upper part of the lug is provided with a threaded segment, which is used for the adjusting nut 5 to adjust the position. The length of the threaded segment can be adjusted according to actual needs. The adjusting nut 5 is a double-nut combination, which is adjusted and locked on the threaded segment of the support rod 4 according to actual needs, so as to ensure that the support cylinder 3 can be reliably supported at any specified position.

[0032] As shown in Fig. 3 When the adjusting nut 5 is adjusted to the appropriate position and locked, and the supported member drives the upper support 1 to rotate to the specified angle, the support cylinder 3 is in contact with the adjusting nut 5, and the supported member cannot continue to rotate and is stopped at the specified position and reliably supported.
