DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figures 1-5As shown, an embodiment of the utility model proposes a connecting pipe for an oxygen concentrator that is easy to install. The connecting pipe for an oxygen concentrator that is easy to install designed in this scheme can improve the convenience of installation of the connecting pipe on the oxygen concentrator and improve the installation stability. It includes a connecting pipe body 1 and a limiting protrusion 2. The outer wall of one end of the connecting pipe body 1 is fixedly connected to the limiting protrusion 2. The end of the connecting pipe body 1 located at the limiting protrusion 2 is sleeved on the oxygen concentrator joint 3. A quick-fitting part 4 is sleeved on the connecting pipe body 1 at the position of the limiting protrusion 2. The quick-fitting part 4 consists of a collar 5, a convex ball 6, a spring 7 and a resistance ring 8. The collar 5 is sleeved on the connecting pipe body 1. A plurality of convex balls 6 are arranged in an annular array on the collar 5. A spring 7 is sleeved on the collar 5. The spring 7 is fixedly connected to the resistance ring 8. The resistance ring 8 is sleeved on the collar 5. When the connecting pipe body 1 is firmly connected to the oxygen concentrator joint 3 through the quick-fitting part 4, the connecting pipe body 1 at one end of the limiting protrusion 2 is aligned with the oxygen concentrator joint 3, and then the connecting pipe body 1 is sleeved with the limiting protrusion 2. Figure 1 The contact ring 8 is pushed in the direction indicated by A in the middle, so that the movable groove 804 inside the contact ring 8 is located at the position of the convex ball 6. At this time, the convex ball 6 can move in the movable hole 502. At this time, the spring 7 will be pulled to retract and maintain the rebound force. When the connecting pipe body 1 is sleeved on the oxygen generator joint 3, when the contact ring 8 is loosened, the spring 7 makes the contact ring 8 rebound. At this time, the contact wall 803 is in contact with the convex ball 6, so that the convex ball 6 is tightly in contact with the outer wall of the connecting pipe body 1, thereby achieving the contact with the outer wall of the connecting pipe body 1, so that the connecting pipe body 1 is tightly sleeved on the oxygen generator joint 3. Figure 1 The direction indicated by B is the oxygen supply. At this time, the connecting pipe body 1 is sleeved on the oxygen concentrator joint 3, and the oxygen concentrator joint 3 is provided with a trapezoidal pattern. The abutment wall 803 abuts against the convex ball 6, so that the connecting pipe body 1 is tightly sleeved on the oxygen concentrator joint 3. Without pushing the abutment ring 8, the abutment wall 803 can maintain the abutment against the convex ball 6, so that the convex ball 6 is tightly abutted against the outer wall of the connecting pipe body 1, thereby strengthening the connection of the connecting pipe body 1, improving the convenience of connection, and the stability of connection.

[0025] An embodiment of the utility model provides a connecting pipe for an oxygen concentrator that is easy to install. An outer ball head 9 is provided at one end of a connecting pipe body 1, and an inner ball head 10 is slidably connected inside the outer ball head 9. One end of the inner ball head 10 is connected to an extension tube 11, so that the extension tube 11 and the connecting pipe body 1 can be connected. When the connecting pipe is bent and needs to be adjusted, the inner ball head 10 can be rotated inside the outer ball head 9 to ensure that it is connected. The flexibility is increased, so that the pipeline can maintain good air tightness and fluidity at various angles, avoid the problem of poor gas supply caused by entanglement and bending of the connecting pipe, and improve the use effect. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0026] likeFigure 3 As shown, in some embodiments, one end of the collar 5 is provided with a sleeving groove 501, and the other end is annularly and arrayedly provided with movable holes 502. The convex balls 6 are movably arranged in the movable holes 502, and the convex balls 6 are in contact with the outer wall of the connecting pipe body 1. The design of the collar 5 meets the sleeving and connecting use on the connecting pipe body 1 to ensure the connecting effect.

[0027] As Figure 4 shown, in some embodiments, the inner wall of one end of the abutting ring 8 is provided with a convex ring 801. The inner wall of the abutting ring 8 on one side of the convex ring 801 is provided with an inner cavity 802. The inner wall of the abutting ring 8 on one side of the inner cavity 802 is provided with an abutting wall 803. The inner wall of the abutting ring 8 on one side of the abutting wall 803 is provided with a movable groove 804. Both the abutting wall 803 and the movable groove 804 are arranged in cooperation with the convex balls 6. The abutting ring 8 meets the abutting of the convex balls 6 to realize the reinforced connection use of the quick-installation part 4 on the connecting pipe body 1.

[0028] As Figure 3 shown, in some embodiments, one end of the spring 7 is fixedly connected to the convex ring 801. The spring 7 is located at the inner cavity 802 part. The other end of the spring 7 is fixedly connected to the collar 5 at the sleeving groove 501 part. The spring 7 acts between the collar 5 and the abutting ring 8 to meet the demand for convenient connection use.
