Description

Technical Field

[0001] The utility model relates to the technical field of quick-connect plugs, in particular to a locking and fixing structure of a quick-connect connector. Background Art

[0002] Quick-connect plugs are a plug-and-play connection method widely used in various applications for their convenience and quick connection. They come in a variety of styles, including miniature, standard, metal, stainless steel, flame-retardant, composite, and drum-type connector combinations. These different types of quick-connect plugs are suitable for different working environments and usage requirements. Their design makes connecting air pipes simple and quick, significantly improving work efficiency in applications where space is limited or connections are difficult. Whether connecting electrical wires or pneumatic pipes, quick-connect plugs provide a stable and reliable connection solution. For example, some quick-connect plugs are designed specifically for power cords, while others are suitable for connecting air pipes in pneumatic systems.

[0003] There are many types of quick-connect plugs on the market. Considering that they need to be locked and fixed during use, their design ideas generally adopt a snap-on design. This design makes plugging in more convenient, but inevitably brings a lot of inconvenience to disassembly. In addition, it is very easy to cause disassembly damage due to incorrect disassembly operation during the disassembly process, thereby causing equipment failure. Therefore, a locking and fixing structure of a quick-connect connector is proposed, which solves the problem that the locking and fixing structure of the traditional quick-connect connector is relatively simple to plug in and fix, but its disassembly process is relatively complicated. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides a locking and fixing structure for a quick-connect connector, which has the advantages of strong practicality and simple operation. It solves the problem that the locking and fixing structure of the traditional quick-connect connector is relatively simple to plug and fix, but its disassembly process is relatively complicated and easily leads to structural damage.

[0005] In order to achieve the above-mentioned purpose of strong practicality and simple operation, the utility model provides the following technical solutions: a locking and fixing structure of a quick-connect connector, including a socket, a plug movably connected to the inside of the socket, a locking component arranged inside the plug, a fixing component arranged inside the socket, and an unlocking component movably connected to the inside of the plug; the locking component includes a sliding groove opened inside the plug, a positioning groove opened on both sides of the plug, a positioning rod fixedly installed inside the positioning groove, a locking buckle movably connected to the outside of the positioning rod, a limiting rod fixedly installed on the side of the locking buckle, a spring plate fixedly installed on the side of the limiting rod, and a locking spring fixedly installed on the side of the spring plate.

[0006] Furthermore, a through hole is provided inside the locking buckle, a positioning rod vertically passes through the locking buckle and is rotatably connected to the locking buckle, and both ends of the locking spring are fixedly mounted to the spring plate.

[0007] Furthermore, the fixing component includes locking grooves provided on both sides of the inner wall of the socket, a plurality of limit grooves provided on the inner wall of the socket, a locking hole provided on the side of the plug, a fixing spring fixedly mounted on the inner wall of the locking hole, and a positioning block fixedly mounted on the side of the fixing spring.

[0008] Furthermore, the locking groove is an oblique groove and its shape matches the shape of the locking buckle, and a limiting baffle with a certain angle is provided on the opposite side of the two locking grooves.

[0009] Furthermore, one end of the positioning block can be embedded in the interior of the limiting groove and slidably connected to the inner wall of the limiting groove, and the end of the positioning block close to the fixing spring is embedded in the interior of the locking hole and slidably connected to the inner wall of the locking hole.

[0010] Furthermore, the unlocking component includes an unlocking block slidably connected to the inside of the sliding groove, a pushing block fixedly installed on the side of the unlocking block, an unlocking groove opened inside the pushing block, a connecting spring fixedly installed on the side of the pushing block, and a connecting groove opened on the inner side wall of the sliding groove.

[0011] Furthermore, the unlocking slot longitudinally passes through both sides of the push block, and the integral structure consisting of the limiting rod, spring plate and locking spring passes through the unlocking slot transversely, and the side surface of the spring plate and the inner side wall of the unlocking slot are slidably connected.

[0012] Furthermore, one end of the connecting spring is embedded in the interior of the connecting groove and fixedly mounted to the inner side wall of the connecting groove.

[0013] Compared with the prior art, the present invention provides a locking and fixing structure for a quick-connect connector, which has the following beneficial effects:

[0014] 1. The locking and fixing structure of the quick-connect connector is as follows: by inserting the plug into the socket, when the plug is completely inserted into the socket, the positioning block is embedded in the limit groove, and the two ends of the locking spring respectively squeeze the spring plate. Under the squeezing action of the spring, the spring plate pushes the limiting rod to drive the locking buckle away from each other, so that the locking buckle is embedded in the locking groove. When the locking buckle is completely embedded in the locking groove, the positioning block is embedded in the limit groove. At the same time, the two ends of the fixing spring are respectively squeezed by the plug and the positioning block, thereby forming a stable structure.

[0015] 2. The locking and fixing structure of the quick-plug connector is to press the unlocking block, and the movement of the unlocking block drives the pushing block to move, and the movement of the pushing block drives the spring plate to move, and the movement of the spring plate drives the locking buckle to rotate. When the rotation of the locking buckle is blocked by the limit baffle at the edge of the locking groove, the plug is pushed to continue to be inserted into the inside of the socket. After the locking buckle moves a certain distance inside the locking groove, it can be smoothly rotated out of the locking groove. While releasing the plug, continue to lightly press the unlocking block until the fixed spring pushes the plug to pop out from the inside of the socket to complete the disassembly of the quick-plug connector, which solves the problem that the locking and fixing structure of the traditional quick-plug connector is relatively simple to plug and fix, but its disassembly process is relatively complicated and easy to cause structural damage.

[0022] A fixing component 4 is provided inside the socket 1 to cooperate with the locking component 3 inside the plug 2 when it is embedded inside. When disassembly is required, the unlocking component 5 inside the plug 2 is pressed and unlocked while moving inside the locking component 3.

[0023] In this embodiment, a through hole is opened inside the locking buckle 34 , the positioning rod 33 vertically passes through the locking buckle 34 and is rotatably connected to the locking buckle 34 , and both ends of the locking spring 37 are fixedly mounted to the spring plate 36 .

[0024] By setting the locking buckle 34 to rotate outside the positioning rod 33, the two ends of the locking spring 37 respectively squeeze the spring plates 36 at both ends, thereby driving the two locking buckles 34 to maintain an expanded state outside the positioning rod 33.

[0025] In this embodiment, the fixing component 4 includes locking grooves 41 opened on both sides of the inner wall of the socket 1, several limiting grooves 42 opened on the inner wall of the socket 1, a locking hole 43 opened on the side of the plug 2, a fixing spring 44 fixedly installed on the inner wall of the locking hole 43, and a positioning block 45 fixedly installed on the side of the fixing spring 44.

[0026] The locking is performed by providing a locking groove 41 , and the limiting groove 42 fixes the insertion position of the positioning block 45 to prevent the socket 1 from moving after insertion, and the locking hole 43 is responsible for receiving the contraction of the positioning block 45 .

[0027] In this embodiment, the locking groove 41 is an oblique groove and its shape matches the shape of the locking buckle 34 . A limiting baffle with a certain angle is provided on the opposite side of the two locking grooves 41 .

[0028] The locking of the device is achieved by providing a locking buckle 34 and a locking groove 41 that cooperate with each other, and the limit baffle limits the movement of the position of the locking buckle 34.

[0029] In this embodiment, one end of the positioning block 45 can be embedded in the interior of the limiting groove 42 and slidably connected to the inner wall of the limiting groove 42, and the end of the positioning block 45 close to the fixing spring 44 is embedded in the interior of the locking hole 43 and slidably connected to the inner wall of the locking hole 43.

[0030] By providing the positioning block 45 , the limiting groove 42 and the locking hole 43 can be extended and retracted, thereby achieving both locking and unlocking effects.

[0031] In this embodiment, the unlocking component 5 includes an unlocking block 51 slidingly connected to the inside of the sliding groove 31, a pushing block 52 fixedly installed on the side of the unlocking block 51, an unlocking groove 53 opened inside the pushing block 52, a connecting spring 54 fixedly installed on the side of the pushing block 52, and a connecting groove 55 opened on the inner wall of the sliding groove 31.

[0032] By designing the unlocking block 51 inside the sliding groove 31 , the pushing block 52 can be driven to slide, thereby driving the unlocking groove 53 to achieve the unlocking effect.

[0033] In this embodiment, the unlocking slot 53 runs longitudinally through both sides of the push block 52, and the integral structure consisting of the limiting rod 35, the spring plate 36 and the locking spring 37 passes horizontally through the unlocking slot 53, and the side surface of the spring plate 36 and the inner side wall of the unlocking slot 53 are slidably connected.

[0034] By arranging the limiting rod 35 and the spring plate 36 to pass through the unlocking slot 53 , the pushing block 52 can push the spring plate 36 to unlock during the movement.

[0035] In this embodiment, one end of the connecting spring 54 is embedded in the connecting groove 55 and fixed to the inner wall of the connecting groove 55 .

[0036] The position of the push block 52 is controlled by connecting the two ends of the connecting spring 54 to the connecting groove 55 and the push block 52 respectively.

[0037] The working principle of the above embodiment is:

[0038] By inserting the plug 2 into the socket 1, when the plug 2 is completely inserted into the socket 1, the positioning block 45 is embedded in the limiting groove 42, and the two ends of the locking spring 37 respectively squeeze the spring plate 36. Under the action of the spring squeezing, the spring plate 36 pushes the limiting rod 35 to drive the locking buckle 34 away from each other, so that the locking buckle 34 is embedded in the locking groove 41. When the locking buckle 34 is completely embedded in the locking groove 41, the positioning block 45 is embedded in the limiting groove 42. At the same time, the two ends of the fixing spring 44 are squeezed by the plug 2 and the positioning block 45 respectively, thereby forming a stable structure.

[0039] In addition, by pressing the unlocking block 51, the movement of the unlocking block 51 drives the pushing block 52 to move, and the movement of the pushing block 52 drives the spring plate 36 to move. The movement of the spring plate 36 drives the locking buckle 34 to rotate. When the rotation of the locking buckle 34 is blocked by the limit baffle at the edge of the locking groove 41, the plug 2 is pushed to continue to be inserted into the inside of the socket 1. After the locking buckle 34 moves a distance inside the locking groove 41, it can be smoothly rotated out of the locking groove 41. While releasing the plug 2, continue to lightly press the unlocking block 51 until the fixing spring 44 pushes the plug 2 to pop out from the inside of the socket 1 to complete the disassembly of the quick-connect connector.
