Description

Technical Field

[0001] The utility model relates to the technical field of oil pipe joints, in particular to an automobile reducing oil pipe joint accessory. Background Art

[0002] The automotive reducer oil pipe fittings market has a wide variety of products, and prices vary according to material, size and customization requirements. There are many suppliers and they provide customization services to meet the growing market demand. These fittings play a key role in the oil system of motor vehicles such as cars and motorcycles. The oil pipe fittings currently on the market are usually composed of two parts: a nut connector and a connector body. This design facilitates the rapid connection of pipelines. However, in the production and manufacturing process, a locking nut machine is required to press and lock these two parts. Since the nut connector and the connector body are sleeved, this may cause the nut connector to fall off or separate during the locking process, which affects the simplicity and efficiency of the locking operation. Utility Model Content

[0003] Based on this, the purpose of the utility model is to provide an automobile reducing oil pipe joint accessory to solve the technical problem that during the production process of the joint accessory, the sleeve connecting parts are prone to falling off and separation, which reduces the convenience of the locking nut operation of the locking nut machine.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automobile reducing oil pipe joint accessory, comprising a nut joint and a joint body, the joint body comprising a connecting head and a plug-in rod, a through pipe is arranged between the connecting head and the plug-in rod, a limiting mechanism is arranged on the outer side of the connecting head, the limiting mechanism comprises an annular groove, and a friction ring is arranged inside the annular groove.

[0005] By adopting the above technical solution, the connector is inserted into the connecting sleeve, and the friction ring on the outside of the connector is tightly abutted against the inner wall of the connecting sleeve, which effectively increases the friction between the two.

[0006] Furthermore, the nut joint includes a nut block, and a connecting sleeve is provided on one side of the nut block.

[0007] By adopting the above technical solution, the joint can be more flexibly adapted to oil pipes of different diameters, thereby improving the versatility and adaptability of the joint. At the same time, the presence of the connecting sleeve facilitates quick and stable connection with the connecting head of the joint body.

[0008] Furthermore, the friction ring is annular in structure and is made of rubber, and the outer side of the friction ring abuts against the inner wall of the connecting sleeve.

[0009] By adopting the above technical solution, the friction ring made of rubber material has good elasticity and friction, which can effectively increase the friction between the connector and the connecting sleeve, and prevent the connector from loosening or falling off when subjected to force or vibration.

[0010] Furthermore, a limiting ring is provided on one side of the plug-in rod, and a groove is formed between the limiting ring, the through pipe and the connector.

[0011] By adopting the above technical solution, the setting of the limiting ring plays a limiting role on the plug-in rod, preventing it from being over-inserted or accidentally disengaged, thereby ensuring the stability and safety of the joint.

[0012] Furthermore, chamfers are provided at the edges and corners of the inner wall of the groove.

[0013] By adopting the above technical solution, chamfering can eliminate stress concentration on the inner wall of the groove, reduce the risk of damage caused by stress concentration during use, and thus improve the structural strength and durability of the joint.

[0014] Furthermore, a slope is provided on the other side of the plug-in rod, and a plurality of guide sealing cones are provided on the outer side of the plug-in rod.

[0015] By adopting the above technical solution, the setting of the inclined surface makes it easier for the plug-in rod to be inserted into the corresponding interface more smoothly, reduces resistance and wear during insertion, and improves installation efficiency.

[0016] Furthermore, the outer surface of the connecting sleeve is a locking nut pressing surface and is engaged with the groove.

[0017] By adopting the above technical solution, a stable and uniform force-bearing surface can be provided when the lock nut operation is performed, thereby ensuring the accuracy and effectiveness of the lock nut operation.

[0018] In summary, the utility model mainly has the following beneficial effects:

[0019] 1. The utility model inserts the connector into the interior of the connecting sleeve through the limiting mechanism. At this time, the friction ring on the outside of the connector fits tightly against the inner wall of the connecting sleeve. The material and design of the friction ring are used to increase the friction between the connector and the connecting sleeve, which not only provides a certain pre-tightening force between the nut joint and the joint body, but also effectively avoids the situation of falling off or separation during the locking process, thereby significantly improving the convenience of the locking operation;

[0020] 2. The utility model carefully arranges chamfers at the edges and corners of the inner wall of the groove, which not only enhances the overall structural strength of the joint body, but also effectively prevents possible breakage during the locking process. This setting detail not only improves the durability and safety of the product, but also further optimizes the processing accuracy and ensures the quality and stability of product production.
