Description

Technical Field

[0001] This utility model relates to pipe connections. Background Technology

[0002] Pipelines are widely used as a crucial final stage for water transfer. Currently, most pipelines are connected using flanges. However, in some temporary connection scenarios, either the pipe at the connection point lacks a flange, or there is insufficient space to install one. Therefore, finding alternative solutions for flanged connections is essential. Furthermore, because pipelines carry water and experience high internal pressure, unstable connections can easily lead to disconnections during use, affecting operational stability.

[0003] As a result, pipe connectors have emerged on the market, which connect two pipes together with a single component. However, these connectors generally suffer from cumbersome connection methods and low connection stability. Utility Model Content

[0007] The clamping member has a clamping cavity with a variable inner diameter. The outer wall of the outer shell has an opening that communicates with the sub-cavity. An operating member abuts against the clamping member through the opening. Under the action of an external force, the operating member moves radially inward to squeeze the clamping member so that the inner diameter of the clamping cavity becomes smaller, thereby clamping the clamping cavity with the pipe.

[0025] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0026] refer to Figures 1-5 This embodiment provides a pipe connector for connecting two pipes 1 together, including: a shell 2, a clamping member 3, and a gland 4;

[0027] The outer casing 2 has a chamber 21 into which the pipe 1 extends, and the inner wall of the chamber 21 is provided with a sub-chamber 22 for installing the clamping member 3; the pressure cap 4 extends from the end of the outer casing 2 into the chamber 21 and abuts against the clamping member 3 to confine the clamping member 3 in the sub-chamber 22.

[0028] The clamping member 3 has a clamping cavity 31 with a variable inner diameter. The outer wall of the outer shell 2 has an opening 23 that connects to the sub-chamber 22. An operating member 5 abuts against the clamping member 3 through the opening 23. Under the action of external force, the operating member 5 moves radially inward to squeeze the clamping member 3, thereby reducing the inner diameter of the clamping cavity 31 and clamping the clamping cavity 31 with the pipe 1.

[0029] The aforementioned pipe 1 connector uses a pressure cap 4 to pre-install the clamping member 3 in the sub-chamber 22 of the outer casing 2, preventing it from falling out of the outer casing 2 or shifting in position. Users can easily insert the pipe 1 to be connected into the chamber 21 of the outer casing 2 and then lock the clamping member 3 using the operating member 5, thus achieving the connection between the clamping member 3 and the pipe 1 clamp. This process is relatively simple and convenient.

[0030] To achieve the goal of changing the inner diameter of the clamping cavity 31 under the pressure of the operating member 5, the clamping member 3 in this embodiment is divided into a first part 32 and a second part 33, which together form the clamping cavity 31. The first part 32 and the second part 33 are each provided with an arc surface, with a protruding rib 34 at one end and a groove 35 at the other end. When the operating member 5 is in its initial position, the protruding rib 34 is partially placed within the groove 35, forming a certain gap between the end of the protruding rib 34 and the bottom of the groove 35. When the operating member 5 presses the clamping member 3, the protruding rib 34 moves towards the bottom of the groove 35. Through the relative movement of the protruding rib 34 and the groove 35, the inner diameter of the clamping cavity 31 can be changed.

[0031] Furthermore, to increase the clamping force between the clamping member 3 and the pipe 1, the clamping member 3 is provided with a protrusion 36 on the inner wall of the clamping cavity 31. The interaction between the protrusion 36 and the pipe 1 increases the friction between the clamping member 3 and the clamping cavity 31, thereby increasing the stability of the clamp and preventing loosening.

[0032] Furthermore, the protrusions 36 are disposed on the inner walls of the arcuate surfaces of the first portion 32 and the second portion 33. There are multiple protrusions 36, spaced apart along the thickness direction of the first portion 32 and the second portion 33. This provides protrusions 36 on both sides of the pipe 1, and increasing the number of protrusions 36 further increases the clamping force between the clamping member 3 and the pipe 1.

[0033] In this embodiment, sub-cavities 22 extend radially outward from the upper and lower sides of the chamber 21, respectively. To install the first part 32 and the second part 33 into the sub-cavities 22, the portion of the first part 32 and the second part 33 placed within the sub-cavities 22 is a platform 37. Placing the platform 37 within the sub-cavities 22 and then using the pressure cap 4 allows the clamping member 3 to be installed within the sub-cavities 22 without loosening. For this purpose, the pressure cap 4 is divided into an insertion part inserted into the outer shell 2 and a limiting part placed outside the outer shell 2. The sidewall of the insertion part is provided with an L-shaped rib 41, and the inner wall of the outer shell 2 is provided with a connecting rib 24 that mates with the L-shaped rib 41. When the connecting rib 24 is connected to the L-shaped rib 41, the limiting part abuts against and limits the end of the outer shell 2. When installing the cover 4, first insert the insertion part of the cover 4 into the outer shell 2 from the end. At this time, the L-shaped rib 41 and the connecting rib 24 are staggered. Then rotate the cover 4 so that the L-shaped rib 41 and the connecting rib 24 are engaged and connected to complete the installation and fixing of the cover 4.

[0034] In this embodiment, the operating component 5 is a set screw. The inner wall of the corresponding opening 23 is threaded, and the user can use a screwdriver or other tools to turn the set screw clockwise, which will allow the set screw to move downward within the opening 23, thereby squeezing the clamping component 3.

[0035] Furthermore, after the two pipes 1 are connected by a connector, there will be a certain gap on their opposite sides, allowing liquid to fill the entire chamber 21. To prevent leakage, a sealing ring 25 is provided on the inner wall of the chamber 21. The sealing ring 25 fits snugly against the outer wall of the pipe 1, forming a sealed cavity and effectively preventing leakage. To further enhance the sealing performance, each pipe 1 has two sealing rings 25, ensuring that even if one sealing ring 25 fails, another sealing ring 25 remains in a sealed state.

[0036] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
