Since the clamping base 1-1 is the main body of the clamping assembly, the structure is hollowed out while ensuring strength to meet the requirements of lightweight.

[0041] The clamping base 1-1 is symmetrically provided with first connecting holes on both sides above, and a second connecting hole is opened at the bottom. The clamping base 1-1 and the telescopic bracket 2 are stacked in sequence, and a telescopic bracket 2 is connected between two adjacent clamping bases 1-1 above and below; the clamping base 1-1 located at the bottom is bolted to the rotating assembly through the second connecting hole, and its top is bolted to the bottom of the telescopic bracket 2 through the first connecting hole, and the top of the telescopic bracket 2 is bolted to the second connecting hole opened at the bottom of the clamping base 1-1 located above. In actual use, when multiple cylindrical equipment needs to be placed, at least two clamping bases 1-1 in the storage cabin can be rotated and erected, and then multiple clamping assemblies can be vertically stacked and connected according to the number of cylindrical equipment. The telescopic bracket 2 and the clamping assembly can be disassembled through the bolt structure to better meet different clamping and storage needs.

[0042] The buckle 1-3 includes an arc-shaped locking card and a hook fixed at one end of the locking card, the other end of the locking card is rotatably connected to one side of the clamping base 1-1 through a rotating bearing 1-6, and the arc-shaped concave surface of the locking card faces the space; two pads 1-2 fixed to the clamping base 1-1 are also provided in the space, the two pads 1-2 are both located below the locking card and are symmetrically arranged along the arc direction of the locking card, and the two The centers of the upper arc surfaces of the pads 1-2 coincide with each other; felt 1-4 is provided on the locking card and the surface of the pad 1-2 facing the space. In order to improve the clamping stability of the mounting cylinder 5, higher installation accuracy requirements are imposed on the pad 1-2 and its mounting surface to ensure that the centers of the upper arc surfaces of the two pads 1-2 coincide with each other as much as possible. A section of 6mm thick felt 1-4 is pasted between the locking card and the two pads 1-2 to prevent damage to the surface of the mounting cylinder 5 when clamped and pressed.

Each telescopic rod 2-1 is composed of two round brackets with a diameter of 12mm and a distance of 50mm. During processing and manufacturing, not only the position accuracy of the axis lines of the two round brackets must be ensured, The cylindricity of the bracket must also be ensured so that it can slide smoothly in the first sliding bearing 2-3. Threaded holes are provided at the ends of the two circular brackets so that they can be fixed in place by screws after being in place. The arrangement of the upper and lower clamping assemblies can realize the clamping of double-layer workpieces. The telescopic bracket 2 can not only realize the adjustable distance between the two cylindrical workpieces after installation, but also reduce the overall size of the mechanism after use, so that the clamping mechanism can be stored and hidden in a storage cabin with limited space. Two telescopic brackets 2 are symmetrically arranged on both sides of the clamping base 1-1 to ensure a stable connection between the two clamping bases 1-1. The telescopic bracket 2 can not only realize the adjustable distance between the two cylindrical equipment after installation, but also reduce the overall size of the mechanism after use, so that it is easy to store and hide in the guide rail 3-1 cabin with limited space.

[0045] A through hole is provided on the support column 2-2, and a threaded hole is provided at the end of the telescopic rod 2-1. The threaded hole cooperates with the through hole.

[0047] The rotating assembly includes a rotating support 3-7 and a connecting shaft 3-4. The bottom of the rotating support 3-7 is located in the storage cabin and is fixed with a second sliding bearing 3-5. The second sliding bearing 3-5 is sleeved on the outside of the connecting shaft 3-4 and is slidably connected to the connecting shaft 3-4. The rotating support 3-7 is bolted to the clamping base 1-1 located at the bottom through the first connecting hole; the connecting shaft 3-4 is fixedly connected to the support ear 3-3, and the axis of the connecting shaft 3-4 is perpendicular to the length center line of the storage cabin. A second bearing end for limiting the second sliding bearing 3-5 is also provided on the rotating support 3-7. There are two covers 3-6, two sliders 3-2 and two guide rails 3-1, and ears 3-3 are provided on the two sliders 3-2. The rotating support 3-7 rotates around the connecting shaft 3-4. When clamping, the rotating support 3-7 is rotated to make the upper mounting surface parallel to the mounting surface of the guide rail 3-1. After the whole is moved to a suitable position along the guide rail 3-1, the rotating support 3-7 is limited by the limiting assembly to realize the position locking of the rotating sliding device 3. When the cylinder clamping mechanism is stored and hidden, the whole mechanism is rotated around the connecting shaft 3-4 to fall over, and then the slider 3-2 is moved to adjust its position in the guide rail 3-1 cabin. The whole operation process is simple, efficient and easy to use.

[0048] The limiting assembly includes a latch seat 3-8 and a quick latch. Both the latch seat 3-8 and the rotating support 3-7 are provided with a socket for inserting the quick latch. When the cylinder is clamped, the rotating support 3-7 is rotated to make the clamping mechanism perpendicular to the storage compartment. The quick latch is inserted into the sockets of the corresponding side walls of the latch seat 3-8 and the rotating support 3-7 in turn, so that the rotating support 3-7 can be limited to prevent it from rotating. Since the structure and function of the quick latch are very mature and common, the quick latch is not shown in detail in the figure.

[0049] The latch seat 3-8 includes a mounting portion and a limiting portion arranged perpendicular to the mounting portion, the insertion hole is arranged on the limiting portion, and the limiting portion is arranged parallel to the outer side of the rotating support 3-7; a first mounting hole is opened on the mounting portion, and a plurality of second mounting holes are opened on the mounting base 4 along the length direction of the storage cabin, and the first mounting hole and the second mounting hole are arranged correspondingly. In order to adapt to different usage occasions and clamp cylindrical equipment of different lengths, a first mounting hole is reserved on the mounting portion of the latch seat 3-8, and more second mounting holes are opened on the mounting base 4. Therefore, it is only necessary to adjust the mounting position of the latch seat 3-8 on the mounting base 4 to realize the position adjustment of the entire clamping mechanism.

[0050] The implementation principle of the present invention is as follows: the mounting base 4 is placed at a suitable position on a small vehicle or ship, and then the rotating support 3-7 is rotated out and limited, and then a suitable number of telescopic brackets 2 and clamping assemblies are selected and installed according to the number of cylindrical equipment workpieces to be placed, and after the cylindrical equipment is sleeved on the mounting cylinder 5, the mounting cylinder 5 is clamped and limited on the corresponding clamping assembly, and the relative positions of the upper and lower adjacent clamping assemblies can be adjusted by the telescopic bracket 2. In addition, if it is a larger cylindrical equipment workpiece, two mounting cylinders 5 can be inserted into the cylindrical equipment workpiece at the same time, and then the two mounting cylinders 5 are respectively connected to the upper and lower corresponding clamping assemblies, and then the telescopic bracket 2 is adjusted to increase the distance between the two mounting cylinders 5, so that the two mounting cylinders 5 can support and limit the cylindrical equipment from the upper and lower ends inside the cylindrical equipment, thereby ensuring the stability of the transportation of larger cylindrical equipment, and the usage method is relatively flexible and can be adjusted according to actual usage.
