Description

Technical Field

[0001] This utility model relates to the field of pipe fittings, and in particular to a pipe fitting for new energy vehicles. Background Technology

[0002] In new energy vehicles, complex and efficient fluid piping systems are crucial for ensuring the safe and reliable operation of their core components. These systems rely heavily on various pipelines to transport media such as coolant, refrigerant, lubricating oil, compressed air, and even high-voltage wiring harnesses. As the core component connecting various parts to flexible hoses in the piping system, the performance of pipe fittings directly affects the system's sealing, reliability, and durability. Currently, widely used pipe fitting technologies are mainly based on traditional threaded or clamp-type connections. These fittings typically require the installation of specific rigid fittings, such as barbed fittings or flange fittings, at the hose end, and then connection and sealing with the system interface are achieved by tightening the threads or clamps.

[0003] However, existing pipe fittings have significant drawbacks and shortcomings when applied to new energy vehicles, especially in scenarios requiring frequent connection / disconnection or maintenance / replacement of hoses. First, they are cumbersome and inefficient: whether threaded or clamped, special tools such as wrenches and clamp pliers are usually required for tightening, which is extremely inconvenient in the space-constrained vehicle chassis or engine compartment, increasing the time and difficulty of assembly and maintenance. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a new energy vehicle pipe connector to facilitate installation and prevent loosening.

[0005] To achieve the above technical objectives, this utility model provides a new energy vehicle pipe connector:

[0006] It includes a connector body, an auxiliary mounting cylinder is rotatably connected to the outer surface of the connector body, a push cylinder is threadedly connected to the inside of the auxiliary mounting cylinder, and anti-slip protrusions are uniformly fixed on the inner wall of the push cylinder.

[0007] Preferably, a connecting protrusion is integrally connected to the outer surface of the connector body, a sliding ring is rotatably connected to the outer surface of the connecting protrusion, a connecting ring groove is provided at the end of the auxiliary mounting cylinder, and the sliding ring is slidably connected to the connecting ring groove.

[0008] Preferably, the slip ring includes a first retaining ring and a second retaining ring, wherein the first retaining ring and the second retaining ring have the same structure.

[0009] Preferably, one end of the second retaining ring has a retaining groove, and the other end of the second retaining ring has a retaining block fixed thereon, wherein the retaining groove and the retaining block cooperate with each other.

[0010] Preferably, a protrusion is fixed at the end of the connector body, and a groove is formed on the outer surface of the protrusion, with a sealing ring embedded inside the groove.

[0011] Preferably, the outer surface of the connector body is integrally connected with a barbed ring, and the barbed ring is located between the protruding head and the connecting protruding ring, and the cross-section of the barbed ring is triangular.

[0012] Preferably, the inner wall of the auxiliary mounting cylinder is fixed with an internal thread, the outer surface of the push cylinder is fixed with an external thread, and the internal thread and the external thread are threadedly connected.

[0013] Preferably, the outer surface of the auxiliary mounting cylinder is uniformly fixed with anti-slip blocks.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0015] 1: An auxiliary installation cylinder is fitted onto the main body of the connector, and a connecting push cylinder is rotated inside the auxiliary installation cylinder. By inserting the hose between the push cylinder and the main body of the connector, and then rotating the auxiliary installation cylinder, the auxiliary installation cylinder drives the push cylinder to move towards the connecting convex ring. The anti-slip teeth increase the friction between the push cylinder and the hose, which in turn drives the hose to move towards the connecting convex ring, thus achieving the effect of convenient assembly.

[0016] 2: Furthermore, if the hose needs to be removed, the auxiliary installation cylinder needs to be rotated in the opposite direction, so that the push cylinder moves in the opposite direction of the connecting protrusion. Due to the friction between the anti-slip protrusion and the hose, as well as the resistance provided by the barbed ring, the push cylinder cannot move if the auxiliary installation cylinder is not actively rotated, thus achieving the effect of preventing loosening.

[0024] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0025] Reference Figure 1-5 A new energy vehicle hose connector includes a connector body 1, with a protrusion 12 fixed at the end of the connector body 1. A groove 13 is formed on the outer surface of the protrusion 12, and a sealing ring 14 is embedded inside the groove 13. A barbed ring 15 is integrally connected to the outer surface of the connector body 1, and the barbed ring 15 is located between the protrusion 12 and the connecting protrusion 11. The cross-section of the barbed ring 15 is triangular. The purpose is to increase the friction between the hose and the connector body 1. The end of the protrusion 12 is wedge-shaped, which makes it easy for the hose to be fitted onto the end of the connector body 1. The sealing ring 14 is used to improve the sealing between the hose and the connector body 1.

[0026] An auxiliary mounting cylinder 3 is rotatably connected to the outer surface of the connector body 1. A connecting protruding ring 11 is integrally connected to the outer surface of the connector body 1. A sliding ring 2 is rotatably connected to the outer surface of the connecting protruding ring 11. A connecting ring groove 31 is opened at the end of the auxiliary mounting cylinder 3, and the sliding ring 2 is slidably connected to the connecting ring groove 31. A pusher cylinder 4 is threadedly connected to the inside of the auxiliary mounting cylinder 3. Specifically, an internal thread 33 is fixed on the inner wall of the auxiliary mounting cylinder 3, and an external thread 42 is fixed on the outer surface of the pusher cylinder 4. The internal thread 33 and the external thread 42 are threadedly connected. Anti-slip teeth 41 are evenly fixed on the inner wall of the pusher cylinder 4. For example, during installation, by inserting the hose between the protruding head 12 and the pusher cylinder 4, the anti-slip teeth 41 are used to increase the friction between the pusher cylinder 4 and the hose. Then, the auxiliary mounting cylinder 3 is rotated, and the auxiliary mounting cylinder 3 can use the internal thread 33 to act on the external thread 42, thereby driving the pusher cylinder 4 to move towards the connecting protruding ring 11, so that the pusher cylinder 4 drives the hose to be fitted onto the connector body 1. There is no need for manual repeated pushing of the hose for installation, which is more labor-saving, especially when installing in a confined space.

[0027] The slip ring 2 includes a first retaining ring 21 and a second retaining ring 22. The first retaining ring 21 and the second retaining ring 22 have the same structure. One end of the second retaining ring 22 has a retaining groove 222, and the other end of the second retaining ring 22 has a retaining block 221. The retaining groove 222 and the retaining block 221 cooperate. For example, the retaining block 221 on the first retaining ring 21 engages with the retaining groove 222 on the second retaining ring 22. Similarly, the retaining block 221 on the second retaining ring 22 engages with the retaining groove 222 on the first retaining ring 21, which facilitates the assembly between the first retaining ring 21 and the second retaining ring 22.

[0028] It is worth mentioning that the narrowest diameter of the auxiliary mounting cylinder 3 and the push cylinder 4 is larger than the maximum outer diameter of the connector body 1. During assembly, the auxiliary mounting cylinder 3 and the push cylinder 4 are first put on the connector body 1, and then the first retaining ring 21 and the second retaining ring 22 are snapped on to complete the connection between the connector body 1, the slip ring 2, the auxiliary mounting cylinder 3 and the push cylinder 4.

[0029] Anti-slip blocks 32 are evenly fixed on the outer surface of the auxiliary mounting cylinder 3, which increases the friction between the user's hand and the auxiliary mounting cylinder 3, making it easier for the user to grip the auxiliary mounting cylinder 3 and apply force.

[0030] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
