Abstract
Description
Technical Field
[0001] This utility model relates to the field of hose connector technology, and in particular to a quick-connect hose connector. Background Technology
[0002] Flexible hoses are essential components in modern industry. They are primarily used as protective conduits for wires and cables, signal wires and cables in automated instruments, and as shower hoses in residential applications, with sizes ranging from 3mm to 150mm. Small-diameter hoses (inner diameter 3mm-25mm) are mainly used for protecting the sensing circuits of precision optical scales and industrial sensors.
[0003] The prior art, disclosed in CN219994705U, discloses a quick-connect hose connector. This connector uses protrusions on the inner side of a convex plug to engage with recesses on the outer side of a concave plug. Since these protrusions are typically elastic to engage with the recesses, they may detach under external force or high water pressure after installation, resulting in poor stability. Furthermore, installation and disassembly require overcoming the elastic force. Therefore, we disclose a quick-connect hose connector to meet these needs. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1 - Figure 4 The embodiments provided by this utility model are as follows:
[0022] A quick-connect hose connector includes a plug 1 and a connector 7. The plug 1 has a mounting hole on its side, and the connector 7 has a mounting groove on its side away from the plug 1. Two hoses 2 are fixedly installed in the mounting hole and the mounting groove, respectively. The connector 7 has a slot 6 on its side near the plug 1. The slot 6 communicates with the mounting groove and is adapted to the plug 1. The outer annular part of the connector 7 has an annular mounting groove 21. Multiple evenly arranged limiting mechanisms are installed in the annular mounting groove 21. The outer annular part of the plug 1 has multiple evenly arranged locking slots 3. The multiple locking slots 3 are respectively installed in conjunction with the multiple limiting mechanisms. The connector 7 is equipped with a compression mechanism, which is installed in conjunction with the multiple limiting mechanisms.
[0023] With the above structure, during installation, the connector 7 is aligned with the slot 6 on the plug 1 and moved. Through the setting of multiple limiting mechanisms, it can be quickly fixed while limiting multiple points in the circumferential direction, making the connection stable. At the same time, the setting of the squeezing mechanism can make multiple limiting mechanisms move, thereby facilitating disassembly later.
[0024] like Figure 3 and Figure 4 As shown, the limiting mechanism includes a rectangular hole 16 opened on the inner wall of the annular mounting groove 21. The rectangular hole 16 is connected to the slot 6. A rectangular locking post 4 is slidably installed in the rectangular hole 16. Both ends of the rectangular locking post 4 extend outside the rectangular hole 16. The rectangular locking post 4 corresponds to the position of the slot 3. A slanted groove 17 is opened on the side of the rectangular locking post 4 near the plug 1. The slanted groove 17 corresponds to the position of the plug 1. The limiting mechanism also includes a mounting rod 14 fixedly installed on the side of the rectangular locking post 4. A right-angled trapezoidal block 13 is fixedly installed at the bottom of the mounting rod 14. The inclined side of the right-angled trapezoidal block 13 is away from the rectangular locking post 4. One end of a spring telescopic rod 15 is fixedly installed at the bottom of the mounting rod 14. The telescopic end of the spring telescopic rod 15 is fixedly installed on the inner wall of the annular mounting groove 21. During installation, the plug 1 is aligned with the slot 6 and moved in. When the plug 1 comes into contact with the multiple inclined slots 17, the plug 1 presses against the multiple inclined slots 17, causing the multiple rectangular locking posts 4 to move. The movement of the multiple rectangular locking posts 4 drives the multiple mounting rods 14 to move, and the multiple spring telescopic rods 15 deform. When the multiple rectangular locking posts 4 correspond to the positions of the multiple slots 3 respectively, the sealing ring 10 is tightly attached to the vertical inner wall of the slot 6. Under the force of the multiple spring telescopic rods 15, the multiple rectangular locking posts 4 enter the multiple slots 3 respectively, thereby limiting the movement at multiple points in the circumferential direction, thus achieving quick insertion.
[0025] like Figure 3 and Figure 4As shown, the extrusion mechanism includes an external thread 22 on the annular side of the connector 7, a threaded sleeve 8 is threaded on the external thread 22, a convex annular groove is provided on the side of the threaded sleeve 8 near the rectangular retaining post 4, a convex annular block 11 is rotatably installed in the convex annular groove, an L-shaped ring 12 is fixedly installed on the side of the convex annular block 11 extending outside the convex annular groove, and a plurality of balls 20 are rotatably installed on the side of the L-shaped ring 12 near the rectangular retaining post 4, and the plurality of balls 20 correspond to the positions of the inclined sides of the plurality of right-angled trapezoidal blocks 13 respectively; the extrusion mechanism also includes a plurality of sliders 19 fixedly installed at the bottom of the L-shaped ring 12, a plurality of sliding grooves 18 are provided on the inner wall of the annular mounting groove 21, and the plurality of sliders 19 are slidably installed in the plurality of sliders 19 respectively. When disassembly is required, the threaded sleeve 8 is rotated. The outer side of the threaded sleeve 8 has friction grooves. The spiral movement of the threaded sleeve 8 causes the convex annular block 11 to rotate in the convex annular groove, bringing the convex annular block 11 closer to the rectangular locking post 4. The movement of the convex annular block 11 drives the L-shaped ring 12 to move. The movement of the L-shaped ring 12 causes multiple balls 20 to press against the inner walls of multiple right-angled trapezoidal blocks 13, thereby causing the multiple right-angled trapezoidal blocks 13 to move. The movement of the multiple right-angled trapezoidal blocks 13 drives multiple mounting rods 14 and multiple rectangular locking posts 4 to move, thereby allowing the multiple rectangular locking posts 4 to move out of the multiple locking slots 3, thus facilitating disassembly.
[0026] like Figure 2 As shown, a sealing ring 10 is installed on the side of the plug 1 near the connector 7, and the sealing ring 10 corresponds to the vertical inner wall of the slot 6. The sealing ring 10 is used to provide a seal.
[0027] like Figure 1 and Figure 2 As shown, multiple guide rods 5 are fixedly installed on the vertical inner wall of the slot 6. The guide rods 5 are inside the slot 6 to prevent damage when not connected. Multiple guide grooves 9 are opened on the side of the plug 1, and the multiple guide rods 5 correspond to the positions of the multiple guide grooves 9 respectively. After the guide rods 5 are inserted into the slots 9, the multiple rectangular locking posts 4 correspond to the positions of the multiple locking slots 3 respectively.
[0028] Working principle:
[0029] During installation, the plug 1 is aligned with the slot 6 and moved in. During the movement, the guide rod 5 is aligned with the guide groove 9. When the plug 1 contacts the multiple inclined grooves 17, the plug 1 presses against the multiple inclined grooves 17, thereby causing the multiple rectangular locking posts 4 to move. The movement of the multiple rectangular locking posts 4 drives the multiple mounting rods 14 to move, and the multiple spring telescopic rods 15 deform. When the multiple rectangular locking posts 4 correspond to the positions of the multiple slots 3 respectively, the sealing ring 10 is tightly pressed against the vertical inner wall of the slot 6. Under the force of the multiple spring telescopic rods 15, the multiple rectangular locking posts 4 enter the multiple slots 3 respectively, thereby limiting the position at multiple points in the circumferential direction, thus achieving quick insertion.
[0030] When disassembly is required, the threaded sleeve 8 is rotated. The outer side of the threaded sleeve 8 has friction grooves. The spiral movement of the threaded sleeve 8 causes the convex annular block 11 to rotate in the convex annular groove, bringing the convex annular block 11 closer to the rectangular locking post 4. The movement of the convex annular block 11 drives the L-shaped ring 12 to move. The movement of the L-shaped ring 12 causes multiple balls 20 to press against the inner walls of multiple right-angled trapezoidal blocks 13, thereby causing the multiple right-angled trapezoidal blocks 13 to move. The movement of the multiple right-angled trapezoidal blocks 13 drives multiple mounting rods 14 and multiple rectangular locking posts 4 to move, thereby allowing the multiple rectangular locking posts 4 to move out of the multiple locking slots 3, thus facilitating disassembly.
[0031] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
