DETAILED DESCRIPTION

[0016] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.

[0017] like Figures 1 to 5 As shown, the present invention provides a wing folding positioning locking device, including a horizontal plate 1, vertical plates 2 are arranged at both ends of the horizontal plate 1, the upper ends of the vertical plates 2 are hingedly connected to the ends of the horizontal plate 1, and the horizontal plate and the two vertical plates 2 are combined to form an inverted U-shaped locking device. The horizontal plate and the vertical plates are both provided with through grooves 3, and guide rails 4 are arranged in the through grooves 3. A plurality of cylinders 5 are installed on the guide rails 4 through sliders. The design can adjust the position of the cylinder according to specific circumstances. The telescopic end of the cylinder 5 points to the area surrounded by the horizontal plate and the two vertical plates 2. Grooves 6 are arranged on the upper parts of both ends of the horizontal plate, and docking joints 7 are arranged in the grooves 6. The lower ends of the vertical plates are provided with docking blocks 8 that cooperate with the grooves, and the bottoms of the docking blocks 8 are provided with docking interfaces 9 that cooperate with the docking joints 7. When multiple locking devices are stacked up and down, as shown in FIG. Figure 2 As shown, the docking block of the locking device on the upper side is inserted into the groove of the locking device on the lower side, and the docking joint 7 is inserted into the corresponding docking port 9 to achieve docking. The adjacent cylinders 5 in the same through groove are connected by a first hose 10, and the cylinder on the lower side of the through groove of the vertical plate is connected to the docking port 9 at the lower end of the vertical plate, and the cylinder body of the uppermost cylinder in the through groove of the vertical plate is connected to the docking joint 7 on the corresponding side of the upper part of the horizontal plate, and the cylinder in the through groove of the horizontal plate close to the end of the horizontal plate is connected to the docking joint 7 on the corresponding side of the upper part of the horizontal plate.

[0018] A first channel 11 is arranged inside the upper end of the vertical plate, and the cylinder body of the uppermost cylinder in the through groove of the vertical plate is connected to the lower end of the corresponding first channel 11 through a second hose. Second channels 12 are arranged inside the two ends of the horizontal plate, and the cylinder in the through groove of the horizontal plate close to the end of the horizontal plate is connected to the inner end of the second channel through a third hose. The second channel is connected to the corresponding docking joint 7 through a third channel 13. When the vertical plate is opened to form an angle of ninety degrees with the horizontal plate, the upper end of the first channel docks with the outer end of the second channel.

[0019] The upper end of the first channel and the outer end of the second channel are both fixedly mounted with sealing rings, and the upper end of the first channel and the outer end of the second channel are butted against each other through the sealing ring to ensure better air tightness.

[0020] A fourth channel is arranged inside the lower end of the vertical plate, the cylinder at the lowermost side in the through groove of the vertical plate is connected to the upper end of the corresponding fourth channel through a fourth hose, and the lower end of the fourth channel is connected to the corresponding docking port.

[0021] A pad cloth 14 is arranged on the inner side of the vertical plate. The pad cloth 14 has a certain elasticity. One end of the pad cloth 14 is fixedly connected to the lower end of the vertical plate, and the other end of the pad cloth is connected to the winding device in the middle of the horizontal plate after passing through the hinge axis at the hinge between the upper end of the vertical plate and the horizontal plate. The telescopic end of the cylinder is fixedly installed with a pressing plate 15, which contacts the corresponding outer side surface of the pad cloth.

[0022] When the cargo 16 is placed inside the locking device, the telescopic end of the cylinder extends and pushes the padding through the pressing plate 15, and the inner side of the padding presses the cargo. This design can increase the squeezing area when fixing the cargo and play a certain protective role.

[0023] A accommodating cavity is provided at the bottom of the transverse plate, and a winding device is arranged in the accommodating cavity. The winding device includes a winding roller 17, and the other end of the pad cloth is connected to the winding roller 17. One end of the central axis of the winding roller extends out of the accommodating cavity and is provided with an inner hexagonal hole 18. A ratchet 19 is fixedly installed at one end of the winding roller 17. A hinged ratchet 20 is provided at the top of the accommodating cavity. One end of the ratchet 20 is connected to the accommodating cavity through a spring. The elastic force of the spring ensures that one end of the ratchet 20 cooperates with the ratchet to prevent the ratchet from reversing by itself. A threaded hole is provided at the top of the accommodating cavity corresponding to the position of the other end of the ratchet 20. An embedded bolt 21 is provided in the threaded hole. The bolt 21 rotates When it moves downward, it can push the other end of the ratchet 20, so that one end of the ratchet 20 is released from the ratchet wheel, and the reversal of the winding roller is realized. Through this design, the tightness of the pad cloth can be adjusted by oneself. For example, the pad cloth is in a relatively loose state at the beginning. When the goods are placed on the inside of the locking device, the user uses a tool to cooperate with the hexagonal hole to rotate the winding roller to pre-tighten the pad cloth. Then the cylinder is extended to clamp the goods inside the locking device through the relatively tight pad cloth. This design can be applied to some irregular goods. The cooperation of the cylinder, the pressure plate and the pad cloth can better wrap the goods and achieve the fixation of the goods.

[0024] The utility model also comprises a sealing cover matched with the butt joint, and the butt joint can be closed by the sealing cover.

[0025] It also includes a bottom plate 22, on which a positioning groove 23 cooperating with the docking block is arranged, and an air supply head 24 connected to the air supply device is arranged in the positioning groove 23, and the air supply head 24 can dock with the docking port 9 of the docking block.

[0026] When in use, multiple devices are stacked, a sealing cover is installed on the uppermost docking joint, the docking block 8 at the lower end of the vertical plate of the lowermost locking device is inserted into the positioning groove 23, the goods are placed inside the locking device, the air supply device outputs gas, and the output gas enters the cylinders of multiple locking devices, and the telescopic ends of all cylinders are extended to squeeze and fix the corresponding goods. Through this device, multiple goods can be quickly fixed and the fixing efficiency is improved, and the squeezing force on the goods can be ensured to be relatively uniform. Placing the goods inside the locking device can protect the more fragile goods and avoid the lower layer of goods being crushed when multiple layers are stacked. The horizontal plate and the vertical plate of the device are both plate-shaped designs, which can reduce the space occupied by the goods placement area. The device can also be folded and can be folded and put away when not in use.

[0027] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention.
