Description

Technical Field

[0001] This utility model relates to the field of pipe fitting connection technology, specifically a double-sealed snap-fit ​​two-way pipe fitting. Background Technology

[0002] The double-seal snap-fit ​​tee fitting is a high-performance pipe connector that uses double-snap-fit ​​connection technology and is mainly used for precise sealing connection of two pipes.

[0003] For example, patent publication number "CN221348342U", entitled "Snap-on Connection Device", includes a connector and a positioning insert. The connector has at least two flow ports, and a support platform is provided circumferentially on the inner wall of the flow port. A first sealing ring is provided on the support platform. The pipe to be connected is inserted into the flow port and abuts against the first sealing ring radially. A positioning slot is provided on the side wall of the flow port. The positioning insert corresponds to each flow port. The positioning insert includes a rod. A protruding ring is provided on the outer wall of the end of the pipe to be connected that is inserted into the flow port. The rod is inserted into the positioning slot. The end of the rod near the end of the pipe to be connected abuts against the protruding ring of the pipe to be connected axially, and the end of the rod away from the end of the pipe to be connected abuts against the side wall of the positioning slot axially. This snap-on connection device has a simple structure, is easy to operate, and can be assembled and disassembled without tools.

[0004] The aforementioned patent describes a method for installation and disassembly where "the positioning plug can be manually inserted into the positioning slot to fix the pipe to be connected in the flow port, and the pipe to be connected can be disassembled by pulling out the positioning plug." This method is simple to operate, but it is not very stable and the positioning plug is prone to falling off during use, which affects the use of the connected pipe. Therefore, a double-seal snap-fit ​​two-way pipe fitting is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a double-sealed snap-fit ​​two-way pipe fitting to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-sealed snap-fit ​​two-way pipe fitting, comprising a first pipe fitting and a connecting pipe, wherein a flexible hose is fixedly connected to one end of the first pipe fitting, a second pipe fitting is fixedly connected to one end of the flexible hose, and snap-fit ​​assemblies are fixedly connected to one end of the first pipe fitting and one end of the second pipe fitting, respectively.

[0007] The buckle assembly has a fixing tube installed inside. The inner wall of the fixing tube is fixed to the outer wall of the first fitting. A clamp is rotatably connected to the inner wall of the fixing tube. A torsion spring is installed at the rotatable connection between the fixing tube and the clamp. A friction wheel is rotatably connected to the outer wall of the fixing tube. A rotating ring is fixedly connected inside the friction wheel for contacting the clamp and applying force to the clamp. A limiting component is installed between the fixing tube and the friction wheel.

[0008] Preferably, the limiting component includes a movable rod, the outer wall of which is movably connected to the inner wall of the fixed tube, a rotating component rotatably connected to the bottom end of the movable rod, and a first-order spring damper installed between the rotating component and the fixed tube.

[0009] Preferably, a limiting ring is fixedly connected to the outer wall of the connecting tube, and the outer wall of the limiting ring has a groove for contacting the bottom end of the card.

[0010] Preferably, the bottom end of the friction wheel is provided with a limiting groove for matching the outer wall of the moving rod, and the outer wall of the friction wheel is provided with a friction groove.

[0011] Preferably, a limiting rod is fixedly connected to the outer wall of the movable rod, and a limiting member is fixedly connected to the outer wall of the fixed tube for contacting the limiting rod to restrict the movement of the movable rod.

[0012] Preferably, the outer wall of the fixed tube has a through hole, and the interior of the friction wheel passes through the through hole to the outer wall of the fixed tube and the outer wall of the rotating ring for fixation.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This double-sealed snap-fit ​​two-way pipe fitting achieves a breakthrough improvement through its double-sealed snap-fit ​​structure. The snap-fit ​​assembly incorporates a fixed pipe, a snap-fit ​​component, a rotating ring, and a friction wheel. Combined with the elastic reset function of the torsion spring, it forms a self-locking snap-fit ​​structure. When the connecting pipe is inserted, the bottom end of the snap-fit ​​component precisely engages with the limiting groove of the limiting ring. The friction wheel enhances the gripping force through its surface texture, enabling the connecting pipe to achieve double locking in both the axial and radial directions, preventing the pipe from becoming loose and affecting its use.

[0015] Meanwhile, the design of the hose itself provides elastic compensation, which can adapt to connection scenarios with bending angle deviation or axial misalignment. By setting the limiting component, the moving rod restricts the friction wheel, preventing the friction wheel from rotating easily, thereby ensuring the stability of the buckle assembly during use.

[0021] 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.

[0022] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a double-sealed snap-fit ​​two-way pipe fitting, including a first pipe fitting 1 and a connecting pipe 6. One end of the first pipe fitting 1 is fixedly connected to a hose 2, and one end of the hose 2 is fixedly connected to a second pipe fitting 3. One end of the first pipe fitting 1 and one end of the second pipe fitting 3 are respectively fixedly connected to snap-fit ​​components 4.

[0023] The fastener assembly 4 has a fixing tube 401 installed inside. The inner wall of the fixing tube 401 is fixed to the outer wall of the first fitting 1. The inner wall of the fixing tube 401 is rotatably connected to the clamp 402. A torsion spring is installed at the rotatable connection between the fixing tube 401 and the clamp 402. The outer wall of the fixing tube 401 is rotatably connected to the friction wheel 404. The friction wheel 404 has a rotating ring 403 fixedly connected inside for contacting the clamp 402 and applying force to the clamp 402. A limiting assembly 5 is installed between the fixing tube 401 and the friction wheel 404.

[0024] The limiting component 5 includes a movable rod 501, the outer wall of the movable rod 501 is movably connected to the inner wall of the fixed tube 401, the bottom end of the movable rod 501 is rotatably connected to a rotating component 502, and a first spring damping device 503 is installed between the rotating component 502 and the fixed tube 401.

[0025] A limiting ring 7 is fixedly connected to the outer wall of the connecting pipe 6. The outer wall of the limiting ring 7 has a groove for contacting the bottom end of the clamp 402.

[0026] The bottom end of the friction wheel 404 is provided with a limiting groove for matching the outer wall of the moving rod 501, and the outer wall of the friction wheel 404 is provided with a friction groove.

[0027] A limiting rod 504 is fixedly connected to the outer wall of the movable rod 501, and a limiting member 505 is fixedly connected to the outer wall of the fixed tube 401 for contacting the limiting rod 504 to limit the movement of the movable rod 501.

[0028] The outer wall of the fixed tube 401 has a through hole, and the interior of the friction wheel 404 passes through the through hole to be fixed to the outer wall of the fixed tube 401 and the outer wall of the rotating ring 403.

[0029] The first pipe fitting and the second pipe fitting 3 are connected by a flexible hose 2. This design allows the two-way pipe fitting to be used at bending angles or when the axes of the two connecting pipes 6 are not aligned. By setting the flexible hose 2, the internal connection between the two connecting pipes 6 can be achieved.

[0030] A limiting ring 7 is fixed to the outer wall of the connecting pipe 6. A groove is provided on the limiting ring 7 to enable the connection of the snap-fit ​​component 4. During installation, the first fitting 1 and the connecting pipe 6 are connected. During the movement of the connecting pipe 6, the limiting ring 7 and the snap-fit ​​component 402 come into contact. Since the snap-fit ​​component 402 and the fixed pipe 401 are rotatably connected, and a torsion spring is installed at the rotatable connection between the snap-fit ​​component 402 and the fixed pipe 401, the snap-fit ​​component 402 can restrict the limiting ring 7 through the groove, thereby enabling the connection between the first fitting 1 and the connecting pipe 6. Similarly, the connection between the second fitting 3 and the other connecting pipe 6 can be achieved.

[0031] When disassembly is required, the moving rod 501 is rotated by the limiting rod 504, and the movement of the limiting rod 504 is controlled by the limiting member 505, so that the moving rod 501 and the friction wheel 404 are separated. Then, the moving rod 501 is restricted by the limiting rod 504 and the limiting member 505. The first spring damper 503 is compressed. When the first spring damper 503 extends, it will enable the moving rod 501 to restrict the rotation of the friction wheel 404. The setting of the rotating member 502 enables the moving rod 501 to rotate during the movement, thereby facilitating the rotation of the limiting member 505 to achieve cooperation with the limiting member 505.

[0032] Rotating the friction wheel 404 causes the rotating ring 403 to rotate. Due to the internal design of the rotating ring 403, the inside of the rotating ring 403 contacts the outer wall of the clamp 402 during rotation. As the rotation angle of the rotating ring 403 increases, the rotation angle of the clamp 402 also increases, thus separating the clamp 402 from the inner wall of the groove. This allows the connecting pipe 6 and the first fitting 1 to separate, ensuring that the first fitting 1 and the connecting pipe 6 will not separate during use, thus guaranteeing the normal use of the fittings. A breakthrough improvement is achieved through a double-sealed snap-fit ​​structure. The snap-fit ​​assembly 4 incorporates the fixing pipe 401, the clamp 402, and the rotating ring. 403 and friction wheel 404, together with the elastic reset function of torsion spring, form a self-locking buckle structure. When the connecting tube 6 is inserted, the bottom end of the clip 402 precisely engages with the limiting groove of the limiting ring 7. The friction wheel 404 enhances the gripping force through surface texture, so that the connecting tube 6 achieves double locking in both axial and radial directions, avoiding the situation where the tubes become loose and affect the use. Through the design of the hose 2, the hose 2 itself has elastic compensation capability, which can adapt to connection scenarios with bending angle deviation or axial misalignment. Through the setting of the limiting component 5, the moving rod 501 restricts the friction wheel 404, so that the friction wheel 404 will not easily rotate, thereby ensuring the stability of the buckle component 4 during use.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
