[0010] The docking assembly is arranged on the clamp and is used to dock and fix the base pipe and the docking pipe.

[0011] In a possible design, the integrated sealing assembly includes a crossbar fixedly arranged on the inner wall of one of the U-shaped sealing seats, a screw is rotatably mounted on the crossbar, and a nut for tightening the two U-shaped sealing seats is threadedly connected to the screw.

[0012] In a possible design, the docking assembly includes four trapezoidal blocks fixedly arranged in a circular array on one side of the clamp, the trapezoidal blocks are provided with threaded holes, and the threaded holes are threadedly connected with bolts for tightening against the outer wall of the docking tube.

[0013] In a possible design, two bevels are symmetrically fixed on the top of the nut and the bolt for facilitating direct manual screwing.

[0014] In a possible design, a buffer sheet for increasing friction is fixedly provided on the inner wall of the tight hoop.

[0015] In a possible design, the buffer sheet is made of hard rubber.

[0016] In a possible design, the bottom end of the bolt is provided with anti-slip grooves for improving friction.

[0017] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0018] The working principle and usage process of this technical solution are as follows:

[0019] When in use, put the tight hoop on the base pipe, adjust the position of the tight hoop so that it fits tightly with the base pipe, and use the crossbar and screw in the integrated sealing assembly to seal. The specific operation is to rotate the upright screw until it is completely inserted into the two U-shaped sealing seats, adjust it to a horizontal state, and then tighten the nut on the screw to tighten the two U-shaped sealing seats so that the tight hoop is firmly fixed on the outer wall of the base pipe;

[0020] Afterwards, place the butt joint pipe close to the base pipe to ensure that the butt joint position is accurate, and use the trapezoidal blocks and bolts in the butt joint assembly to tighten the four bolts separately so that they pass through the corresponding threaded holes until the bottom end of the bolt is close to the outer wall of the butt joint pipe. You can use tools to continue tightening the bolts until the required tightness is reached. The anti-slip grooves at the bottom end of the bolts will increase friction to ensure that the bolts will not loosen. After completing the butt joint installation, check whether all fasteners are secure to ensure that there is no looseness or leakage, and perform necessary tests, such as pressure tests, to ensure the reliability and safety of the connection device.

[0021] The utility model has the following beneficial effects:

[0022] The utility model uses an integrated design to tightly combine key components such as the tight hoop, U-shaped sealing seat, integrated sealing assembly and docking assembly to form an overall structure. This design greatly reduces the number of scattered parts, making the entire device more compact and convenient for unified storage and carrying.

[0023] The design of the integrated sealing component and docking component in the utility model makes the installation process simpler and faster. The user only needs to screw the nuts and bolts to complete the connection without using complicated tools or performing tedious operations. This not only improves the installation efficiency but also reduces the installation cost.

[0024] The buffer plate on the inner wall of the tightening hoop and the anti-slip groove design at the bottom end of the bolt in the utility model effectively increase the friction between the connecting device and the pipe, ensuring the tightness and stability of the connection; the top of the nut and the bolt are both provided with inclined plates, which are convenient for direct manual tightening without the use of tools.

[0025] The utility model not only solves the problem in the prior art of having too many scattered parts and being inconvenient to store and carry in a unified manner, but also improves the installation efficiency and ensures the tightness and stability of the connection.

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "opening", "upper", "middle", "length", "inner" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0033] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0034] Example 1

[0035] Please refer to Figure 1-4 A quick connection device, the structure of which mainly includes a tight hoop 1, a U-shaped sealing seat 2, an integrated sealing component and a docking component:

[0036] The clamp 1 is designed as a two-section hinged ring structure, with U-shaped sealing seats 2 fixedly welded at both ends of the notch. The design of these two U-shaped sealing seats 2 allows the clamp 1 to be firmly fixed to the outer wall of a base pipe through them;

[0037] The integrated sealing assembly is designed to secure a clamp 1 to the outer wall of a base pipe. Specifically, a crossbar 3 is welded to the inner wall of one of the U-shaped sealing seats 2. A screw 4 is rotatably mounted on the crossbar 3, and a nut 5 is threadedly connected to the screw 4. The specific operation is to rotate the upright screw 4 until it fully enters the two U-shaped sealing seats 2 and adjust them to a horizontal position. When the screw 4 is horizontal, tightening the nut 5 will push the other U-shaped sealing seat 2 toward it, thereby securing the device to the base pipe through the clamp 1.

[0038] The docking assembly is used to fix the base pipe and the docking pipe. On one side of the tight hoop 1, four trapezoidal blocks 6 are fixedly welded in a circular array. These trapezoidal blocks 6 are provided with threaded holes 7. Each threaded hole 7 is threaded with a bolt 8. When these bolts 8 are tightened, their bottom ends will be tightly against the outer wall of the docking pipe, thereby achieving a fixed connection between the base pipe and the docking pipe.

[0039] Through an integrated design, the device tightly combines key components such as the tight hoop 1, the U-shaped sealing seat 2, the integrated sealing assembly and the docking assembly to form an overall structure. This design greatly reduces the number of scattered parts, making the entire device more compact and convenient for unified storage and carrying.

[0040] This application can be used for multifunctional HVAC pipe docking installation, and can also be used in other fields applicable to this application.

[0041] Example 2

[0042] Improvements based on Example 1:

[0043] A multifunctional HVAC pipe quick connection device, which is used in the field of pipe connection devices;

[0044] Please refer to Figure 1In order to more conveniently screw the nut 5 and the bolt 8, two bevel pieces 9 are symmetrically fixed on their top ends. The design of these bevel pieces 9 allows people to easily screw these fasteners manually without using any tools, which not only improves the installation efficiency but also reduces the installation cost.

[0045] Please refer to Figure 1 A layer of buffer sheet 10 is fixedly set on the inner wall of the tight hoop 1 to increase the friction and increase the tightness between the device and the base pipe. This buffer sheet 10 is made of hard rubber material. It not only provides sufficient friction, but also reduces the wear of the device on the surface of the base pipe to a certain extent.

[0046] Please refer to Figure 4 , further improved the design of the bolt 8. Specifically, anti-slip grooves 11 are provided at the bottom end of the bolt 8. These anti-slip grooves 11 are also used to increase friction to ensure that the bolt 8 can be more firmly fixed to the outer wall of the butt joint after tightening, to prevent loosening due to vibration or external force.

[0047] However, as is well known to those skilled in the art, the working principle of the tight hoop 1 is commonplace, and is a conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0048] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. The embodiments of the present utility model and the features of the embodiments can be combined with each other unless there is a conflict. Therefore, the scope of protection of the present utility model shall be based on the scope of protection of the claims.
