[0024] By providing a fluid loading and unloading arm with a quick connection and locking mechanism in the embodiments of the present application, the technical problem that the connection between the nut and the threaded rod becomes loose due to environmental vibration or improper operation, thereby affecting the connection stability between the fluid loading and unloading arm and the liquid tank truck, is effectively solved. Embodiment

[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 And Figure 7 , the technical solutions in the embodiments of the present application effectively solve the technical problem that the connection between the nut and the threaded rod becomes loose due to environmental vibration or improper operation, thereby affecting the connection stability between the fluid loading and unloading arm and the liquid tank truck. The general idea is as follows:

[0026] In view of the problems existing in the prior art, the utility model provides a fluid loading and unloading arm with a quick connection and locking mechanism. The fluid loading and unloading arm with a quick connection and locking mechanism includes a joint 1. A fixing mechanism is arranged outside the joint 1. The fixing mechanism includes a sliding ring 2, an installation pipe 3, a nut cover 4, a fixing ring 5 and a spring 6. The sliding ring 2 is slidably connected to the outside of the joint 1. There are four installation pipes 3, and the four installation pipes 3 are all arranged outside the sliding ring 2. There are four nut covers 4, and the four nut covers 4 are respectively fixedly installed outside the four installation pipes 3. The fixing ring 5 is fixedly installed at one end of the joint 1 close to the sliding ring 2. There are four springs 6, and the four springs 6 are all fixedly connected to one side of the fixing ring 5 close to the sliding ring 2. The other end of the spring 6 is fixedly connected to the outside of the sliding ring 2. By setting the sliding ring 2 and cooperating with the nut cover 4, the sliding ring 2 is pushed to make the sliding ring 2 away from the flange on the joint 1. At this time, the spring 6 is compressed. When the flange on the joint 1 is docked with the flange on the vehicle, the threaded rod fixed by the flange of the vehicle enters the through hole opened by the flange of the joint 1. At this time, the nut is threadedly connected to the outside of the threaded rod. Then the sliding ring 2 is released. Under the action of the spring 6, the installation pipe 3 and the nut cover 4 are quickly slidably connected to the outside of the threaded rod and the nut. At this time, the nut cover 4 is sleeved outside the nut to prevent the nut from rotating. At this time, the nut cover 4 locks the nut to prevent the nut from loosening due to vibration or improper operation, improving the connection stability between the fluid loading and unloading arm and the liquid tank truck.

[0027] A protective cover 7 is arranged outside the sliding ring 2. The protective cover 7 is slidably connected to the outside of the fixing ring 5. The protective cover 7 can cover the spring 6 to provide protection for the spring 6. Threaded holes 8 are opened at both ends of the sliding ring 2. Fixing screws 9 are movably connected to both ends of the protective cover 7. The fixing screws 9 are threadedly connected to the inside of the threaded holes 8, facilitating the disassembly and assembly of the protective cover 7. A clamping block 10 is fixedly installed outside the protective cover 7. A clamping groove 11 is opened outside the joint 1. The clamping block 10 is adapted to the clamping groove 11. A sliding groove 12 is opened at one end of the joint 1 close to the clamping groove 11. The sliding groove 12 is composed of two identical grooves and a long groove. An insertion plate 13 is slidably connected to the inside of the sliding groove 12. The insertion plate 13 is composed of an L-shaped plate and three rectangular parallelepiped plates. A slot 14 is opened outside the clamping block 10. The insertion plate 13 is slidably connected to the inside of the slot 14. By setting the clamping block 10 and cooperating with the insertion plate 13, when the flange on the joint 1 is docked with the flange on the vehicle, the sliding ring 2 is pushed to make the clamping block 10 clamped in the clamping groove 11. At this time, the insertion plate 13 is pushed to make the insertion plate 13 enter the inside of the slot 14. At this time, the sliding ring 2 is fixed. At this time, the staff can threadedly connect the nut to the outside of the threaded rod, avoiding the sliding ring 2 from affecting the operation of the staff.

[0028] Four rotating grooves 15 are provided on the outside of the sliding ring 2, and a rotating shaft 16 is rotatably connected to the inside of each rotating groove 15. The rotating shaft 16 is fixedly installed on the outside of the installation pipe 3, and the installation pipe 3 is adjusted to sleeved the nut cover 4 on the outside of the nut.

[0029] Working principle:

[0030] First step, before the flange on the joint 1 is docked with the flange on the vehicle, push the sliding ring 2 so that the block 10 is clamped inside the slot 11. At this time, the spring 6 is compressed. Then push the plug 13 so that the plug 13 enters the inside of the slot 14, and at this time the sliding ring 2 is fixed.

[0031] Second step, at this time, the flange on the joint 1 can be docked with the flange on the vehicle. At this time, the threaded rod fixed by the flange of the vehicle enters the through hole opened by the flange of the joint 1. Then thread the nut onto the outside of the threaded rod. At this time, move the plug 13 to release the connection between the plug 13 and the slot 14. Then push the block 10 to release the connection between the block 10 and the slot 11. At this time, under the action of the spring 6, the sliding ring 2 slides so that the installation pipe 3 and the nut cover 4 slide on the outside of the threaded rod and the nut. At this time, the nut cover 4 is sleeved on the outside of the nut. If the nut cover 4 cannot be smoothly sleeved on the outside of the nut, at this time, the nut cover 4 can be rotated so that the threaded cover is smoothly sleeved on the outside of the nut.

[0032] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
