Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a quick-insertion connector device with an automatic calibration function. Background Art

[0002] Generally speaking, water pipe joints have very high requirements for ease of assembly and disassembly, and locking reliability, especially in certain application scenarios where quick assembly and disassembly and leak-proof reliability are extremely high. Currently, there are two commonly used ways to lock water pipe joints. One is to use two separate clamps, which are threaded and fixed with screws and nuts on both sides. The other is to use quick connectors. This device requires two connectors to fit tightly, which is laborious and costly to assemble and disassemble. At the same time, the assembly and disassembly positions need to be lubricated and maintained regularly to ensure ease of assembly and disassembly, which is very inconvenient to use.

[0003] After searching, Chinese patent CN220488551U discloses a quick-connect connector, including a connecting tube and a connector body, wherein the connector body is inserted into the connecting tube, wherein a plug-in assembly for fixing the connector body is provided in the connecting tube, wherein the plug-in assembly includes a cavity, wherein the cavity is provided in the connecting tube, wherein a slide plate is provided for sliding in the cavity. In this utility model, the force rod is pulled so that the force rod drives the slide plate to squeeze the first buffer spring, and then the connector body is plugged into one end of the connecting tube, and then the pulled force rod is released so that the slide plate is driven by the elastic force of the first buffer spring to drive the positioning rod to be clamped in the positioning rod to fix the connector body, and when the two connector bodies are inserted into the connecting tube, the second telescopic rod and the second buffer spring can contact the sealing ring to contact the two connector bodies, thereby improving the sealing of the two connector bodies.

[0004] The utility model quick-plug connector realizes docking installation of the connector through the cooperation of multiple springs, but the multiple springs can only be pressed individually. With this method, when the connector needs to be disassembled, the cooperation of several people is required to press the multiple springs to realize the detachment of the two pipes. This method not only requires the cooperation of multiple people, but also increases the disassembly and assembly steps of the pipes, making it inconvenient for one person to disassemble and assemble, so it cannot meet the use requirements. Therefore, a quick-plug connector device with automatic calibration function is proposed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 A quick-connect connector device with an automatic calibration function includes an inner shell 2 sleeved on the outside of two quick-connect connectors 1, an outer shell 3 is fixedly mounted on the outer surface of the inner shell 2, and a sealing structure is arranged inside the inner shell 2, and the sealing structure includes an elastic component 5 and a sealing block 6 mounted on the side of the elastic component 5 close to the quick-connect connector 1. The quick-connect connector 1 is inserted into the inner shell 2, and the elastic component 5 causes the sealing block 6 to contact the two quick-connect connectors 1, thereby improving the sealing of the two quick-connect connectors 1. The interior of the inner shell 2 is hollow, and both ends are connected. An installation groove 4 is provided inside the inner shell 2, and the side of the elastic component 5 away from the sealing block 6 is fixed to the inner wall of the installation groove 4.

[0024] The elastic component 5 is composed of a return spring and a telescopic rod, and the return spring surrounds the outside of the telescopic rod.

[0025] In this embodiment, a calibration connection structure connected to the quick-connect connector 1 is provided inside the shell 3; the calibration connection structure includes a first L-rod 8 and a second L-rod 9 provided inside the shell 3 and extending outside thereof, a first return spring 11 and a second return spring 15 provided inside the shell 3 and respectively fixed to one side of the first L-rod 8 and the second L-rod 9, a guide wheel 12 provided inside the shell 3, and a pull rope 13 fixedly installed between the first L-rod 8 and the second L-rod 9 and passing through the outer surface of the guide wheel 12.

[0026] It should be noted that a cavity 7 is provided inside the housing 3, a mounting seat 14 is installed on the inner wall of the cavity 7, a side of the second return spring 15 away from the second L-shaped rod 9 is fixed to the outside of the mounting seat 14, and a side of the first return spring 11 away from the first L-shaped rod 8 is fixed to the inner wall of the cavity 7. The two protruding parts of the first L-shaped rod 8 and the second L-shaped rod 9 are hooked to achieve the limitation of each other.

[0027] In addition, when the second L-rod 9 is not connected to the slot, the second L-rod 9 will abut against the outer wall of the quick-connect connector 1, and the quick-connect connector 1 can be docked and tested. At this time, the quick-connect connector 1 can be rotated to connect the second L-rod 9 to the slot, thereby achieving automatic correction.

[0028] In this embodiment, the inner shell 2 and the outer shell 3 are provided with a through hole communicating with the cavity 7, and a slot adapted to the second L-rod 9 is provided inside one of the quick-connect connectors 1, and the second L-rod 9 extends through the through hole to the outside of the outer shell 3 and is plugged into the slot. The end of the pull rope 13 close to the second L-rod 9 passes through the inside of the mounting seat 14 and the second return spring 15.

[0029] In this embodiment, the number of the sealing structures is four, and the four sealing structures are symmetrically distributed in groups of two, and a handle 10 is installed between two adjacent first L-shaped rods 8 .

[0030] A pulley 16 is installed on the side of the first L-shaped rod 8 away from the second L-shaped rod 9 by bolts, and a slide groove 17 is provided inside the cavity 7, and the pulley 16 is rollingly connected to the inner wall of the slide groove 17.

[0031] The working principle of the above embodiment is:

[0032] When in use, the handle 10 is pressed to extend the first L-rod 8 toward the inside of the housing 3 and squeeze the first return spring 11. The displacement of the first L-rod 8 drives the second L-rod 9 through the pull rope 13 and the guide wheel 12 to extend it toward the inside of the housing 3. Then the quick-connect connector 1 is inserted into the inner housing 2. The elastic component 5 causes the sealing block 6 to contact the two quick-connect connectors 1, thereby improving the sealing of the two quick-connect connectors 1. Finally, the pressure of the handle 10 is released. Through the reaction force of the first return spring 11, the first L-rod 8 and the second L-rod 9 are extended toward the outside of the housing 3 to fix the quick-connect connector 1. In addition, when the second L-rod 9 is not connected to the slot, the second L-rod 9 will contact the outer wall of the quick-connect connector 1, so that the quick-connect connector 1 can be docked and detected. At this time, the quick-connect connector 1 can be rotated to connect the second L-rod 9 to the slot to achieve automatic correction.
