[0030] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] The utility model provides a pipeline connection locking device, such as Figure 1-Figure 6 As shown, the pipeline connection locking device is used for connecting two sets of connecting pipes 100, and includes:

[0032] A connecting member 200, the connecting member 200 comprises a first connecting end 210, a second connecting end 220 and a connecting section 230, the first connecting end 210 and the second connecting end 220 are connected via the connecting section 230; the first connecting end 210 and the second connecting end 220 are connected to different connecting pipes 100 respectively;

[0033] The locking member 300 includes a shaft 340, a dial plate 330 disposed on the shaft 340, and deflection blocks 320 disposed at both ends of the shaft 340, and different deflection blocks 320 extend into the first connection end 210 and the second connection end 220 respectively;

[0034] In the present application, the shaft 340 is not arranged at the axis of the deflection block 320. When the dial plate 330 rotates, the deflection block 320 limits and locks the connection pipe 100 inserted into the connecting member 200 under the eccentric action.

[0035] In this embodiment, the structures of the first connection end 210 and the second connection end 220 are substantially the same. The first connection end 210 and the second connection end 220 are symmetrically arranged on different end surfaces of the connecting section 230. The first connection end 210 and the second connection end 220 are both provided with a sealing assembly 240.

[0036] When the connecting pipe 100 is inserted into the first connecting end 210 or the second connecting end 220, the sealing assembly 240 will generate a blocking force on the connecting pipe 100 under the action of friction, and then the dial plate 330 will be toggled, and the deflection block 320 will extend into the first connecting end 210 or the second connecting end 220 under the action of deflection and abut against the peripheral side of the sealing assembly 240. At this time, the abutment force generated by the deflection block 320 will exert a greater pressure on the connecting pipe 100, so that the connecting pipe 100 cannot be easily moved or rotated; the linkage structure and eccentric force action are used here to simplify the locking mechanism after the pipe fittings are docked, reduce the operation process of the operator, and complete the pipe fitting docking needs at both ends through a synchronous locking method; while meeting the fixed locking needs, the workload of the operator is reduced, and the assembly efficiency of the quick-connect equipment is improved;

[0037] As a preferred implementation in this embodiment, the first connecting end 210 is taken as an example, the first connecting end 210 is provided with a rear limit groove 211 at one end close to the connecting section 230, and the first connecting end 210 is provided with a front guide groove 212 at the end away from the connecting section 230;

[0038] The sealing assembly 240 includes a flexible sealing ring 241, a front sealing ring 242 and a rear sealing ring 243. The flexible sealing ring 241 is disposed between the front sealing ring 242 and the rear sealing ring 243.

[0039] The front sealing ring 242 is a bell-mouth structure and is adapted to the front guide groove 212. The bell-mouth structure is mainly used to alleviate the impact force during the insertion process by using the inclined surface, and at the same time facilitates the insertion of the connecting pipe 100;

[0040] The rear sealing ring 243 is located in the rear limiting groove 211;

[0041] In this embodiment, the front sealing ring 242 and the rear sealing ring 243 are both made of hard rubber material, which has high hardness and sealing performance. The flexible sealing ring 241 is made of a thin silicone material. When the deflection block 320 is deflected, it abuts against the outside of the flexible sealing ring 241. Under the abutment, the flexible sealing ring 241 is tightly attached to the inner wall of the connecting pipe 100 and generates a great friction force to prevent the movement of the connecting pipe 100.

[0042] As a preferred implementation in this embodiment, the locking member 300 further includes a plurality of mounting seats 310; an extension opening 213 is provided on the first connecting end 210, the deflection block 320 enters the first connecting end 210 from the extension opening 213, and the mounting seats 310 are arranged on both sides of the extension opening 213, the shaft rod 340 rotates in the shaft hole provided on the mounting seat 310, and the deflection block 320 and the dial plate 330 are fixedly connected to the shaft rod 340, so when the dial plate 330 deflects, the deflection block 320 synchronously deflects around the mounting seat 310 driven by the shaft rod;

[0043] In this embodiment, two sets of mounting seats 310 are also provided on one side of the second connecting end 220 to provide rotation support for the shaft 340; when the plate 330 is away from the end of the shaft 340 and close to the outer wall of the connecting section 230, the eccentric force generated by the deflection block 320 is greater; on the contrary, when the plate 330 is away from the end of the shaft 340 and close to the outer wall of the connecting section 230, the eccentric force generated by the deflection block 320 is smaller, and the friction force on the connecting pipe 100 is smaller, and the connecting pipe 100 is more likely to leave the connecting member 200;

[0044] In this embodiment, at least two groups of locking members 300 are provided around the connecting member 200. The locking members 300 are distributed in a circular array on the connecting member 200 and are fixed by upper limits in different directions to further enhance the strength of the docking.

[0045] The working principle of this application is as follows;

[0046] First, the connecting tube 100 is inserted into the first connecting end 210 and the second connecting end 220 respectively, and the sealing assembly 240 completes the primary fixation. The sealing assembly 240 assumes the main sealing function in this process. After the plugging is completed, the multiple groups of dial plates 330 located on the peripheral side of the connecting piece 200 can be simultaneously moved by gripping to quickly complete the limit locking, and the two groups of connecting tubes 100 can be quickly connected through the connecting piece 200. When disassembly is required, the operation can be reversed to complete the disassembly;
