[0002] Quick-connect fittings are the most convenient plug-and-play connection method, especially in some inconvenient and difficult space situations where air pipe connections are difficult. Quick-connect fittings are divided into the following types: 1. Small; 2. Standard; 3. Metal; 4. Stainless steel; 5. Flame retardant; 6. Composite; 7. Drum-type fitting combination;

[0003] Most of the quick-connect plugs in the prior art are large in size and difficult to assemble in a narrow space with dense pipelines. Most of the existing quick-connect plugs do not have good locking and clamping capabilities when connecting two sets of pipes. They usually have a large activity space. When in use, the two sets of pipes cannot provide sufficient stability and sealing effect. The medium in the pipes will leak and lose to a certain extent, affecting the practicality and sealing effect of the plug. Therefore, we need to upgrade and transform the existing technology to overcome its existing problems and shortcomings. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 As shown in Figure 4, the present embodiment provides a quick-connect connector suitable for a small space, including a device body 1, the device body 1 includes an upper tube body 2 and a lower tube body 3, a connector 4 is arranged at the upper end of the lower tube body 3, and the connector 4 is inserted into the upper tube body 2 from bottom to top, a clamping ring 5 is arranged in the middle of the lower tube body 3, and side openings 6 are symmetrically opened on both sides of the clamping ring 5, a hinge seat 7 is arranged on the side of the upper tube body 2, and a rotating shaft 8 is installed on the inner side of the hinge seat 7, and torsion springs 9 are sleeved on both sides of the rotating shaft 8, and the other end of the torsion spring 9 is connected to the outer wall of the upper tube body 2. On the upper part, a movable rod 10 is connected to the lower end of the rotating shaft 8 and a lower clamping head 11 is provided at the bottom of the movable rod 10. An embedded groove 12 is provided on the outer wall of the connecting head 4 and a sealing sleeve 15 is installed in the embedded groove 12. The outer wall of the sealing sleeve 15 is sealed and fitted on the inner wall of the upper tube body 2. An inner cavity 151 is provided inside the sealing sleeve 15. Three groups of elastic sheets 152 are arranged at equal intervals inside the inner cavity 151. The elastic sheets 152 and the inner cavity 151 are used to elastically support the sealing sleeve 15, so as to always maintain the sealing and fitting effect between the sealing sleeve 15 and the inner wall of the upper tube body 2.

[0024] Preferably, an outer ring body 31 is provided on the outer side of the lower end of the lower tube body 3, and a plurality of anti-slip grooves 32 are provided on the outer ring body 31 in a ring array. The outer ring body 31 and the anti-slip grooves 32 facilitate manual insertion of the lower tube body 3. The clamping ring 5 is configured as a conical structure, and the lower clamping head 11 is elastically clamped on the clamping ring 5. The side opening 6 corresponds to the lower clamping head 11. The clamping ring 5 and the lower clamping head 11 facilitate clamping and limiting of the upper tube body 2 and the lower tube body 3. By rotating the lower tube body 3, the lower clamping head 11 can be aligned with the side opening 6 and disengaged from each other.

[0025] Preferably, a lower sealing groove 13 is provided inside the upper tube body 2, a lower sealing ring 16 is provided on the connecting head 4 and the lower sealing ring 16 corresponds to the lower sealing groove 13, and the lower sealing groove 13 and the lower sealing ring 16 cooperate to facilitate the sealing reinforcement of the connecting head 4, and an upper sealing groove 14 is provided inside the upper tube body 2, an upper sealing ring 17 is provided on the connecting head 4 and the upper sealing ring 17 corresponds to the upper sealing groove 14, and the upper sealing ring 17 and the upper sealing groove 14 cooperate to facilitate secondary sealing reinforcement of the connecting head 4.

[0026] The use principle and use process of the utility model are as follows: when in use, first install the sealing sleeve 15 in the embedded groove 12 on the outer side of the lower tube body 3, then install the lower sealing ring 16 and the upper sealing ring 17 on the upper end of the connector 4, insert the lower tube body 3 into the upper tube body 2 through the connector 4, so that the lower sealing ring 16 and the upper sealing ring 17 are respectively sealed and fitted in the lower sealing groove 13 and the upper sealing groove 14, and the sealing sleeve 15 is tightly fitted on the inner wall of the upper tube body 2 through the elastic sheet 152 and the inner cavity 151. During the plug-in process, the lower clamping head 11 and the movable rod 10 are in contact with the tapered clamping ring 5. The lower clamping head 11 moves outward under the action of the clamping ring 5, and the rotating shaft 8 pushes the torsion spring 9 to rotate inside the hinge seat 7. When the lower clamping head 11 moves to the lower end of the clamping ring 5, the lower clamping head 11 and the movable rod 10 lose the force, and the torsion spring 9 elastically resets and pushes the rotating shaft 8 to reset accordingly. At this time, the movable rod 10 and the lower clamping head 11 elastically reset and move to the lower end of the clamping ring 5. The lower tube body 3 cannot be pulled out from the inside of the upper tube body 2 to the outside. When it needs to be separated, the lower tube body 3 is rotated so that the side opening 6 corresponds to the position of the lower clamping head 11. At this time, the lower tube body 3 can be pulled out to the outside.

[0027] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
