Description

Technical Field

[0001] This application relates to the field of hose devices, and more particularly to a hydraulic hose that is convenient to connect. Background Art

[0002] The hydraulic hose mainly consists of an inner rubber layer resistant to liquids, a middle rubber layer, a 2- or 4- or 6-layer steel wire winding reinforcement layer, and an outer rubber layer. The inner rubber layer enables the conveyed medium to bear pressure and protects the steel wire from erosion. The outer rubber layer protects the steel wire from damage, and the steel wire layer is the framework material that plays a reinforcing role.

[0003] The connection of the existing hydraulic hose usually adopts a threaded connection with a stainless steel joint. When the pressure of the medium in the hose is relatively high, it is necessary to tightly tighten the threaded joint. When disassembling and assembling the connection multiple times, the phenomenon of thread wear and slippage will occur, affecting the connection tightness. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, this application provides a hydraulic hose that is convenient to connect.

[0005] The hydraulic hose that is convenient to connect provided by this application adopts the following technical solutions:

[0006] A hydraulic hose that is convenient to connect, including a hose body, a male connection head fixedly arranged at one end of the hose body, and a female connection head fixedly arranged at the other end of the hose body;

[0007] The male connection head includes a connecting pipe, and an annular groove is formed on the outer peripheral surface of the connecting pipe;

[0008] The female connection head includes a pipe shell and a snap ring slidably arranged on the outer peripheral surface of the pipe shell. A convex ring is arranged on the inner side surface of the snap ring. A step groove is formed on the pipe shell. A spring is elastically abutted between the convex ring and the step groove. A plurality of card holes are evenly formed on the pipe shell along the circumferential surface. A card ball that matches the annular groove is clamped in the card hole, and the diameter of the card ball is larger than the aperture of the card hole.

[0009] Further, a circular ring-shaped dial is fixedly arranged on the outer peripheral surface of the snap ring.

[0010] Further, both side edges of the annular groove and the side surface of the convex ring facing away from the spring are in a slope-shaped structure.

[0011] Further, a convex edge for abutting against the convex ring is fixedly arranged at the port of the pipe shell. When the convex ring abuts against the convex edge, the convex ring blocks the card holes.

[0012] This application has the following beneficial technical effects:

[0013] By providing a male connecting head and a female connecting head at both ends of the pipe body, the male connecting head can be directly inserted into the female connecting head and clamped and fixed, realizing the quick connection of the hydraulic hose, so as to change the length of the hose, which can be used frequently and has a relatively long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 is a schematic cross-sectional structure diagram of an embodiment of the present application.

[0015] Reference numerals: 1, pipe body; 2, connecting pipe; 21, annular groove; 3, pipe shell; 31, snap ring; 32, convex ring; 33, stepped groove; 34, spring; 35, locking hole; 36, locking ball; 4, paddle; 5, convex edge. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the present application will be further described in detail below with reference to the accompanying drawings.

[0017] An embodiment of the present application discloses a hydraulic hose that is convenient to connect. Please refer to Figure 1 , a hydraulic hose that is convenient to connect includes a pipe body 1, a male connecting head fixedly provided at one end of the pipe body 1, and a female connecting head fixedly provided at the other end of the pipe body 1.

[0018] Among them, the male connecting head includes a connecting pipe 2, and an annular groove 21 is formed on the outer peripheral surface of the connecting pipe 2.

[0019] Among them, the female connecting head includes a pipe shell 3 and a snap ring 31 slidably arranged on the outer peripheral surface of the pipe shell 3. A convex ring 32 is arranged on the inner side surface of the snap ring 31. A stepped groove 33 is arranged on the pipe shell 3. A spring 34 is elastically abutted between the convex ring 32 and the stepped groove 33. A plurality of locking holes 35 are uniformly formed on the pipe shell 3 along the circumferential surface. A locking ball 36 that cooperates with the annular groove 21 is clamped in the locking hole 35. The diameter of the locking ball 36 is larger than the aperture of the locking hole 35.

[0020] When the male connecting head and the female connecting head are docked, the snap ring 31 can be slid and the spring 34 can be compressed. The convex ring 32 disengages from the opening of the locking hole 35. At this time, the connecting pipe 2 is inserted into the pipe shell 3, and the locking ball 36 is pushed outwards until the locking hole 35 is aligned with the annular groove 21. The snap ring 31 is reset and the convex ring 32 pushes the locking ball 36 into the locking hole 35. The part of the locking ball 36 embedded in the locking hole 35 is embedded in the annular groove 21, preventing the connecting pipe 2 from disengaging from the pipe shell 3. At the same time, the convex ring 32 blocks the locking hole 35 and abuts against the locking ball 36 to realize clamping and fixing.

[0021] A flange 5 for abutting against the convex ring 32 is fixedly arranged at the port of the shell 3. When the convex ring 32 abuts against the flange 5, the convex ring 32 covers the card hole 35. When the male connector and the female connector are snap-fastened, the convex ring 32 abuts against the flange 5, which can prevent the snap ring 31 from falling off the shell 3.

[0022] Both side edges of the annular groove 21 and the side surface of the convex ring 32 facing away from the spring 34 are of a slope structure. This is to facilitate snapping the clamping ball 36 into the annular groove 21 and separating the clamping ball 36 from the annular groove 21.

[0023] Furthermore, a dial 4 in a circular ring structure is fixedly arranged on the outer peripheral surface of the snap ring 31. This is to facilitate pushing the snap ring 31 open through the dial 4 and prevent the phenomenon that it is difficult to operate due to wet hands.

[0024] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
