Description

Technical Field

[0001] This utility model relates to the field of rubber hose technology, specifically a high-stability rubber hose connector. Background Technology

[0002] Hose fittings are commonly used connecting devices in hydraulic systems to connect different components and pipes, enabling fluid transmission and control.

[0003] Existing hose fittings involve inserting the connecting tube inside the fitting into the hose, and then wrapping the outside of the hose with a clamp. When subjected to vibration or pressure fluctuations, the clamp is prone to loosening, leading to liquid leakage. In high-pressure environments, the sealing performance is insufficient, making it difficult to meet the needs of industrial pipelines, hydraulic systems, and other applications requiring high stability. Utility Model Content

[0004] The purpose of this utility model is to provide a highly stable hose connector. Through the cooperation of the connector assembly, connecting groove and protrusion, the protrusion of the hose body and the hook of the inner wall of the retainer form a mechanical limit, which effectively prevents the axial movement of the hose. The hose body and the annular gap thread connection enhance the connection stability. The combination of multiple structures achieves a stable connection, enhances stability, and reduces the risk of leakage.

[0005] This utility model is achieved through the following technical solution: This utility model is a high-stability hose connector, including a connector assembly. The connector assembly includes an outer shell, an inner shell fixedly connected to the inner wall of the outer shell, a retainer fixedly connected to the upper and lower ends of the outer shell, a barb fixedly connected to the inner wall of the retainer, a clamp sleeved on the outer wall of the outer shell, a hose body threadedly connected to the inner wall of the inner shell, a connecting groove opened at one end of the hose body, and a raised ridge surrounding the outer wall of the hose body.

[0006] Furthermore, the outer shell is cylindrical with openings at both the top and bottom, and the card holders are funnel-shaped with openings running through them from top to bottom. One end of each card holder is positioned opposite to the top and bottom of the outer shell, and a circumferential groove is provided between the opposite side of the two card holders and the outer side of the outer shell.

[0007] Furthermore, a circumferential extension plate is provided in the middle of the outer wall of the inner shell. The inner shell is welded to the middle of the inner wall of the outer shell through the extension plate. The inner shell, outer shell, and extension plate are combined to form two annular gaps on the inner wall of the outer shell. The inner wall of the annular gap is provided with internal threads.

[0008] Furthermore, the inner wall of the clamp abuts against the outer wall of the annular groove, and the clamp is locked in the annular groove by a locking device. The inner side wall of the connecting groove is provided with an external thread, and the hose body is threaded into the annular gap through the external thread of the inner side wall of the connecting groove.

[0009] Furthermore, the bottom end of the connecting groove abuts against the bottom surface of the inner wall of the annular gap, the protrusion and the barb engage with each other, the outer edge of the protrusion abuts against the side wall of the card seat, and the outer edge of the barb abuts against the outer wall of the hose body.

[0010] This utility model has the following beneficial effects: This utility model uses a connector assembly, a connecting groove, and a protruding rib to cooperate. The protruding rib on the outside of the hose body engages with the hook on the inner wall of the card holder to form a mechanical limit, which effectively prevents the hose from moving axially. The hose body and the annular gap thread connection enhance the connection stability. The combination of multiple structures achieves a stable connection, enhances stability, and reduces the risk of leakage.

[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0014] 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.

[0015] Please see Figure 1-5This utility model provides a technical solution: a high-stability hose connector, including a connector assembly 1. The connector assembly 1 includes an outer shell 101, an inner shell 104 fixedly connected to the inner wall of the outer shell 101, and retainers 102 fixedly connected to the upper and lower ends of the outer shell 101. The outer shell 101 is cylindrical with openings at both ends. The retainers 102 have a funnel-shaped cross-section with openings at both ends. One end opening of the two retainers 102 is respectively positioned opposite each other at the upper and lower ends of the outer shell 101. A circumferential groove is provided between the opposite side of the two retainers 102 and the outer side of the outer shell 101. A barb 103 is fixedly connected to the inner wall of the retainer 102. A circumferential extension plate extends from the middle of the outer wall of the inner shell 104. The inner shell 104 is welded to the middle of the inner wall of the outer shell 101 through the extension plate. The inner shell 104, the outer shell 101, and the extension plate are combined to form two annular gaps on the inner wall of the outer shell 101. The inner wall of the annular gaps is provided with internal threads. A sleeve is provided on the outer wall of the outer shell 101. The clamp 2 has a threaded connection to the inner wall of the inner sleeve 104, and the hose body 3 is connected to it. One end of the hose body 3 has a connecting groove 4. The inner wall of the clamp 2 abuts against the outer wall of the annular groove. The clamp 2 is locked in the annular groove by a locking component, which is a bolt assembly passing through both ends of the clamp 2. The bolt assembly includes a bolt and a nut. Tightening the nut can tighten the clamp 2, thereby further securing the hose connector. The inner wall of the connecting groove 4 has an external thread, and the hose body 3 passes through the inner wall of the connecting groove 4. The external thread is connected in the annular gap. The outer wall of the hose body 3 is surrounded by a protruding rib 5. The protruding rib 5 is arranged around the circumference of the hose body 3. The barb 103 is arranged in a ring shape on the side wall of the card holder 102. The bottom end of the connecting groove 4 abuts against the bottom surface of the inner wall of the annular gap. The protruding rib 5 and the barb 103 are engaged with each other to form a mechanical limiting structure to prevent the hose body 3 from moving axially. The outer edge of the protruding rib 5 abuts against the side wall of the card holder 102, and the outer edge of the barb 103 abuts against the outer wall of the hose body 3.

[0016] First, place this device in the designated working position. During installation, align the end of the hose body 3 with the connecting groove 4 with the inner sleeve 104. Screw the hose body 3 between the inner sleeve 104 and the outer sleeve 101 by engaging the external thread on the inner side wall of the connecting groove 4 with the internal thread on the inner wall of the annular gap. During the screwing process, the protruding rib 5 on the outer wall of the hose body 3 and the barb 103 on the inner wall of the clamp 102 engage with each other to form a mechanical limit, preventing the hose body 3 from moving axially. Then, put the clamp 2 on the annular groove on the outer wall of the outer sleeve 101, so that the inner wall of the clamp 2 abuts against the outer wall of the groove. Then, pass the bolt assembly through both ends of the clamp 2 and tighten the nut to tighten the clamp 2, further securing the hose joint and completing the assembly of the high-stability hose joint, achieving stable connection and sealing.
