Description

Technical Field

[0001] This utility model belongs to the technical field of oil cooler pipeline connection structure, specifically a quick-connect connector for oil cooler pipelines. Background Technology

[0002] With the increasing level of industrialization, the application range of oil coolers is becoming more and more widespread, placing higher demands on the connection technology of oil cooler pipelines. The common connection method for existing oil cooler pipelines mostly uses a combination of rubber hoses and clamps. Rubber hoses and clamps are simple in structure, low in cost, and offer a certain degree of flexibility, thus they are widely used in oil cooler pipeline connections. However, this connection method has some significant drawbacks, mainly in the following aspects:

[0003] Low assembly efficiency: Traditional hose and clamp connection methods require manual operation, involving connecting the pipes one by one and tightening the clamps, a relatively cumbersome process. Especially in situations requiring frequent disassembly and reassembly, the labor intensity for assembly personnel is high, and the connection time is long, affecting production efficiency.

[0004] Poor connection stability: The connection between the hose and the clamp depends on the clamp's tightening force and the hose's elasticity. However, due to long-term use, the clamp may loosen due to high-frequency vibration, weakening the clamp's tightening force and causing leakage problems, which increases the risk of system failure.

[0005] Increased spare parts management costs: Additional clamps are needed, increasing spare parts inventory and supply pressure, and increasing overall production and operation costs. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a quick-connect connector for oil cooler pipes, aiming to solve the problems of low assembly efficiency, poor connection stability, and high spare parts management costs associated with existing hose and clamp connection methods. The connector includes a straight pipe section, a fixed interface section, and a bend section. The straight pipe section is used to connect to the hose, and the fixed interface section is used to fix it to the oil cooler body. The bend section connects to the straight pipe section and the fixed interface section at both ends, with their axes perpendicular to each other. The bend section and the fixed interface section are riveted to form a second extrusion part protruding from the circumferential surface. This second extrusion part limits the insertion depth of the fixed interface section into the oil cooler. A cylindrical insert is riveted to the straight pipe section, and the cylindrical insert is used for quick connection to the hose and to prevent the hose from detaching.

[0007] Preferably, the cylindrical insert is sleeved and installed on the straight pipe section, the bent pipe section and the straight pipe section are riveted to form a first extrusion section protruding from the circumferential surface, the end of the straight pipe section away from the bent pipe section is provided with a flared section by cold drawing, and the cylindrical insert is stuck between the first extrusion section and the flared section.

[0008] Preferably, the cylindrical insert has a fastening conical surface on the side facing the flared portion for forming a compression seal on the connected tubing.

[0009] Preferably, the large-diameter end of the fastening cone surface is provided with a recessed groove that is recessed into the circumferential surface, and the recessed groove is used to form a barbed fit on the edge of the extruded tubing.

[0010] Preferably, the end face of the flared portion is provided with a guide cone surface that narrows towards the axis, the guide cone surface being used to reduce the difficulty of inserting and connecting the sleeved tubing.

[0011] Preferably, the small-diameter end of the guide cone surface is provided with a rounded corner that is turned inward toward the axis.

[0012] Preferably, the cylindrical insert has a circumferential protrusion protruding from the circumferential surface, which is used to limit the depth of the tubing inserted into the cylindrical insert.

[0013] Compared with the prior art, this utility model provides a quick-connect connector for oil cooler pipes, which has the following advantages:

[0014] The quick-connect connector design reduces the time required for manual clamp operation in traditional connection methods. The connector completes assembly through automatic locking and sealing, greatly improving assembly efficiency. By simplifying the connection method, this utility model reduces reliance on clamps, lowers spare parts inventory and supply pressure, and thus reduces the overall operating costs of enterprises.

[0019] Example

[0020] The following is combined Figure 1 and Figure 2 This application introduces a quick-connect connector for oil cooler pipes, comprising a straight pipe section 2, a fixed interface section 4, and a bent pipe section 1. The straight pipe section 2 is used to connect to a rubber hose, and the fixed interface section 4 is used to fixally connect to the oil cooler body. The two ends of the bent pipe section 1 are respectively connected to the straight pipe section 2 and the fixed interface section 4, with their axes perpendicular to each other. The bent pipe section 1 and the fixed interface section 4 are riveted to form a second extrusion section 5 protruding from the circumferential surface. The second extrusion section 5 is used to limit the depth of the fixed interface section 4 inserted into the oil cooler. A cylindrical insert 8 is fixed to the straight pipe section 2 by press riveting. The cylindrical insert 8 is used to quickly connect to the rubber hose and form an anti-detachment fixation for the rubber hose.

[0021] The cylindrical insert 8 is sleeved and installed on the straight pipe section 2. The bent pipe section 1 and the straight pipe section 2 are riveted to form a first extrusion section 3 protruding from the circumferential surface. The end of the straight pipe section 2 away from the bent pipe section 1 is provided with a flared section 6 by cold drawing. The cylindrical insert 8 is stuck between the first extrusion section 3 and the flared section 6.

[0022] The cylindrical insert 8 has a fastening cone surface 9 on the side facing the flared part 6 for forming a compression seal on the connected tubing.

[0023] The large-diameter end of the fastening cone 9 is provided with a recessed groove 10 that is recessed into the circumferential surface. The recessed groove 10 is used to form a barbed fit on the edge of the extruded hose, further strengthening the connection strength between the hose and the cylindrical insert 8.

[0024] The end face of the flared part 6 is provided with a guide cone surface 7 that narrows towards the axis. The guide cone surface 7 is used to reduce the difficulty of inserting and connecting the sleeved tubing.

[0025] The small-diameter end of the guide cone 7 is provided with a rounded corner 11 that is turned inward toward the axis to reduce damage to the tubing during connection.

[0026] The cylindrical insert 8 has a circumferential protrusion 12 protruding from the circumferential surface. The circumferential protrusion 12 is used to limit the depth of the tubing into the cylindrical insert 8, so as to avoid the tubing being inserted too deeply and affecting the sealing performance of the connector. Furthermore, due to the protruding rotating surface, it can also form a rotation limit for the cylindrical insert 8 and the tubing.
