Technical Field

[0001] This utility model relates to the field of pipe connection, and in particular to a novel concentric reducer connection structure. Background Technology

[0002] A reducer is a common pipe fitting, mainly used to connect two sets of pipes with different diameters. Depending on the position of the center point of the connection, it can be divided into concentric reducers and eccentric reducers. A concentric reducer has two connection points with the center lines collinear, and is mainly used for two sections of two sets of collinear reducers.

[0003] Since the middle part of the reducer is usually inclined, welding is usually used to connect the reducer and the pipeline for easy connection. However, this makes it impossible to disassemble and reuse the reducer later, and the overall device is not economical. Therefore, a new concentric reducer connection structure is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 5 The present invention provides an embodiment of a novel concentric reducer connection structure, comprising a reducer 1 for connecting pipes, a connecting component 2 for sealing the connection at the right end of the reducer 1, the connecting component 2 including a housing sleeve 210 for accommodating a sliding ring 211, the housing sleeve 210 being fixedly connected to the outer wall of the reducer 1, and a fixing component 3 for fixing a lever 213 being provided on the outer wall of the housing sleeve 210, the fixing component 3 including a rotating ring 31 for driving a rubber block 32 to rotate, the rotating ring 31 being rotatably connected to the outer wall of the housing sleeve 210, the rotating ring 31 being able to rotate on the outer wall of the housing sleeve 210 but not being able to move left or right.

[0032] Reference Figure 2 - Figure 4The connecting assembly 2 also includes a fixing ring 21 for supporting the plastic spring sheet 22. The fixing ring 21 is fixedly connected to the outer wall of the reducer 1. The right end of the fixing ring 21 is fixedly connected to the plastic spring sheet 22 for compressing the sealing sleeve 23. The plastic spring sheet 22 is made of plastic and has elastic deformation capability. It will bend when compressed. The inner wall of the plastic spring sheet 22 is fixedly connected to the sealing sleeve 23 for compressing the pipeline. The top end of the plastic spring sheet 22 is fixedly connected to the inclined block 24 for compressing the plastic spring sheet 22. The outer wall of the fixing ring 21 is slidably connected to the compression sleeve 25 for compressing the inclined block 24. The outer wall of the connecting assembly 2 is rotatably connected to the left end near the fixing ring 21 to drive the arc sleeve 27 to rotate. The inner wall of the rotating sleeve 26 is fixedly connected to the arc sleeve 27 for compressing the compression sleeve 25. The arc sleeve 27 and the compression sleeve 25 are adapted to each other. By rotating the rotating sleeve 26, the arc sleeve 27 can be driven to rotate. When the arc sleeve 27 rotates, it will compress the compression sleeve 25 and make it move to the right.

[0033] Reference Figure 1 - Figure 3 The outer wall of the rotating sleeve 26 is fixedly connected to an anti-slip block 28 for easy rotation by the operator. The left end of the anti-slip block 28 is fixedly connected to a locking block 29 for fixing the rotating sleeve 26. The inner wall of the storage sleeve 210 is slidably connected to a sliding ring 211 for fixing the locking block 29. The right end of the sliding ring 211 is provided with a slot 212 for accommodating the locking block 29. The slot 212 and the locking block 29 are compatible. When the locking block 29 is engaged in the slot 212, the rotating sleeve 26 will be fixed and unable to rotate backward. The left end of the sliding ring 211 is fixedly connected to a fixing spring 214 for pushing the sliding ring 211. The left end of 14 is fixedly connected to the inner wall of the storage sleeve 210. The fixing spring 214 will push the sliding ring 211 to the right at all times. The top of the sliding ring 211 is fixedly connected to a lever 213 for the operator to move the sliding ring 211. The lever 213 slides on the right end of the storage sleeve 210. By moving the lever 213, the sliding ring 211 can be separated from the locking block 29. The fixing component 3 also includes a rubber block 32 for blocking the lever 213. The rubber block 32 is fixedly connected to the outer wall of the rotating ring 31. The rubber block 32 and the lever 213 are compatible. By squeezing the lever 213 with the rubber block 32, it can be prevented from moving to the left.

[0034] Working principle: When it is necessary to connect the pipeline, the pipeline to be connected can be inserted into the right end of the reducer 1. Then, the rotating sleeve 26 can be rotated to drive the arc sleeve 27 to rotate. The rotation of the arc sleeve 27 will squeeze the compression sleeve 25, forcing the compression sleeve 25 to move to the right. The compression sleeve 25 moving to the right will squeeze the inclined block 24. The inclined block 24 being squeezed will squeeze the plastic spring 22 inward. The plastic spring 22 being squeezed will bend and squeeze the sealing sleeve 23. The sealing sleeve 23 will squeeze the outer wall of the pipeline, thus achieving the fixing effect.

[0035] Once the pipeline is secured, the anti-slip block 28 can be slowly released. The fixing spring 214 will push the sliding ring 211 to move it to the right, causing the locking block 29 to engage inside the slot 212. At this point, the rotating sleeve 26 will not be able to rotate backward. Then, the rotating ring 31 can be rotated to drive the rubber block 32 to rotate. The rubber block 32 will block the left end of the slot 212, preventing it from moving to the left. In this way, the pipeline is secured.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
