[0002] Pipe connectors are an indispensable component of the piping system. They are mainly used to connect different pipes or the transition between pipes and equipment. They are usually made of rubber, PVC, metal and other materials. They have high flexibility, corrosion resistance and shock absorption characteristics. They are widely used in building drainage systems, industrial piping systems, fire protection facilities and air conditioning systems.

[0003] At present, the pipe connections of PVC pipes usually adopt the connection methods of rubber ring, socket, bonding and threaded connection. Among them, the connection method of socket connection is less stable and tight. When bonding, the selection and application of adhesive have a great influence on the bonding quality. The connection efficiency is low and there are certain operation requirements. Secondly, the connection methods of socket and threaded connection cause greater damage to the connection of PVC pipe orifice. For PVC pipes with thinner walls, it is easy to cause deformation of the pipe wall. It is inconvenient to operate and it is easy to cause further damage to the main body of the PVC pipe. Utility Model Content

[0004] The purpose of the utility model is to provide a quick connector for pipes, which facilitates the connection operation and can further improve the support of the pipe wall at the pipe mouth and reduce the deformation or even damage of the pipe wall, thereby improving the connection stability and sealing with the pipe.

[0008] Furthermore: the end surfaces of the first connecting seat and the second connecting seat body surrounding the plurality of slots are arranged in an arc shape.

[0009] Furthermore: the slots opened around the second connecting seat body are staggered with the slots opened around the first connecting seat body, and the end faces of the slots opened around the second connecting seat body are arranged in a direction away from both ends of the connecting rod.

[0010] Furthermore: the number of slots provided on the first connecting seat body is smaller than the number of slots provided on the second connecting seat body.

[0011] Furthermore: a plurality of sealing strips are evenly arranged around and on the seat body corresponding to the notch of the second connecting seat.

[0012] Furthermore: the lock rings rotatably provided on the connecting parts at both ends of the connecting rod are provided with adaptable ribs on both sides corresponding to the end faces of the seat body of the first connecting seat and the connecting rod.

[0013] Furthermore: the rod structure between the ribs on both sides of the connecting rod is made of transparent material.

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0024] See also Figure 1-2 The present embodiment relates to a quick connector for a pipe 100, comprising a connecting rod 1, connecting parts 2 are provided at both ends of the connecting rod, and a locking ring 3 is rotatably provided on the connecting part 2, the connecting part 2 comprises a first connecting seat 21 and a second connecting seat 22 embedded in the first connecting seat 21, an installation groove 23 is provided between the first connecting seat 21 and the second connecting seat 22, and a plurality of notches 24 are opened around the seat bodies of the first connecting seat 21 and the second connecting seat 22.

[0025] Specifically in this embodiment, see Figure 2As shown, when using this pipe 100 quick connector to adapt the pipe 100 structure to connect the PVC pipe 100, the pipe mouth of the corresponding PVC pipe 100 can be respectively plugged into the connecting parts 2 at both ends of the connecting rod. When the pipe mouth is plugged along the mounting groove 23 between the first connecting seat 21 and the second connecting seat 22, the second connecting seat 22 is placed inside the pipe 100 and fits against the inner wall of the pipe mouth. At the same time, the first connecting seat 21 is placed outside the pipe 100 and fits against the outer wall of the pipe mouth. Then, as the pipe mouth of the pipe 100 continues to move into the mounting groove 23, the adaptation size of the mounting groove 23 can be slightly smaller than the wall thickness of the pipe 100 when selected, so that during the connection process of the pipe 100, the first connecting seat 21 and the second connecting seat 22 can, under the action of several notches 24 arranged around its seat body, enable the second connecting seat 22 and the first connecting seat 21, which are respectively fitted with the inner and outer walls of the pipe mouth of the pipe 100, to produce an appropriate degree of deformation without affecting the normal rotation and locking process of the lock ring 3. At the same time, the lock ring 3 structure provided at both ends of the connecting rod 1 can adopt a conventional threaded connection method and be rotated and connected through the threaded structure 211 correspondingly provided on the outer periphery of the seat body of the first connecting seat 21. Therefore, through the adaptive rotation of the lock ring 3 on the first connecting seat 21, the pipe mouth in the mounting groove 23 between the first connecting seat 21 and the second connecting seat 22 can be locked, thereby realizing the connection process of the pipe 100 on the connecting part 2. The specific state after the connection is completed can be seen in Figure 1 As shown in the figure, the setting of the connecting part 2 in this pipe 100 connector can not only realize the quick connection of the pipe 100, but also does not require bonding, is convenient to operate and has low operating requirements. At the same time, the structural setting of the first connecting seat 21 and the second connecting seat 22 in the connecting part 2 can further improve the connection stability with the pipe 100, improve the connection efficiency, and effectively avoid the degree of damage to the pipe wall caused by the conventional threaded connection method during the connection process. In addition, the setting of the second connecting seat 22 can also play a certain supporting role on the inner wall of the pipe 100 compared with the conventional socket connection method, effectively reducing the probability of pipe wall deformation or even damage to the main body of the pipe 100 due to the thin pipe wall. At the same time, the setting of the first connecting seat 21 and its outer locking ring 3 can further improve the installation adaptability and connection stability with the pipe 100.

[0026] The seat body of the second connecting seat 22 on the connecting part 2 at both ends of the connecting rod is arranged in a trumpet shape, and the end face of the seat body is arranged as an inclined surface 221 and a redundant length is extended outward along the two ends of the connecting rod. The adapting seat body structure of the second connecting seat 22 arranged in a trumpet shape and the setting of the inclined surface 221 on the end face of the seat body can facilitate the plugging process of the pipe mouth in the installation groove 23, and at the same time can further reduce the degree of deformation of the first connecting seat 21 and the second connecting seat 22 caused during the plugging process of the pipe mouth, and the setting of its redundant length cooperates with the outer seat body structure of the first connecting seat 21, which can further improve the fit and connection stability of the connecting part 2 to the pipe mouth of the pipeline 100, and further improve the effect of the first connecting seat 21 and the second connecting seat 22 on the pipeline 100 during the connection process of the pipeline 100.

[0027] The end faces 241 of the plurality of notches 24 formed around the base bodies of the first connecting seat 21 and the second connecting seat 22 are arranged in an arc shape. The arc-shaped end faces 241 of the notches 24 can effectively disperse the concentrated stress at the notches 24 of the base bodies during the connection of the first connecting seat 21 and the second connecting seat 22 with the pipeline 100, further improve the stability of the base body structure of the first connecting seat 21 and the second connecting seat 22, and reduce the unnecessary impact of the notches 24 on the overall structure of the base body, thereby improving the stability during use and appropriately extending the service life.

[0028] The slot 24 opened around the seat body of the second connecting seat 22 is staggered with the opening position of the slot 24 opened around the seat body of the first connecting seat 21, and the end face 241 of the slot 24 opened around the seat body of the second connecting seat 22 is set in the direction away from the two ends of the connecting rod. The slot 24 with this position setting method can further improve the plugging effect of the pipe 100 on the connecting part 2, and during the plugging process, the pipe mouth in the installation groove 23 can ensure that its pipe wall completely blocks the slot 24 on the second connecting seat 22, thereby further improving the connection effect of the first connecting seat 21 and the second connecting seat 22 and the sealing of the inside of the pipe 100 and the inside of the connecting rod 1, and effectively reducing the leakage of liquid in the pipe 100.

[0029] The number of the slots 24 on the first connecting seat 21 is smaller than the number of the slots 24 on the second connecting seat 22. Figure 2It can be seen that the corresponding number of notches 24 on the first connecting seat 21 and the second connecting seat 22 can ensure that the overall structure of the first connecting seat 21 and the second connecting seat 22 has a certain strength, while further improving the structural stability of the first connecting seat 21 and the deformation strength of the second connecting seat 22, thereby further improving the connection effect of the connecting part 2, ensuring the effective connection length of the pipe mouth in the installation groove 23 and the optimal locking effect of the locking ring 3 on the connecting rod 1, and improving the connection stability of this type of pipeline 100 connector.

[0030] A plurality of sealing strips 222 are arranged around and evenly arranged on the seat body of the second connecting seat 22 corresponding to the notch 24. The setting of the sealing strips 222 on the seat body of the second connecting seat 22 can further reduce the degree of wear on the inner wall of the pipe orifice, and at the same time can further improve the fit between the second connecting seat 22 and the inner wall of the pipe orifice, and further improve the sealing effect between the connecting part 2 and the pipe orifice of the pipe 100. At the same time, the setting of the plurality of sealing strips 222 can also increase the friction force at the connection with the pipe 100, further improve the connection stability of the connecting part 2, thereby effectively reducing the phenomenon of the pipes 100 connected to the connecting parts 2 at both ends of this pipe 100 quick connector falling off during use.

[0031] The locking ring 3 rotatably provided on the connecting parts 2 at both ends of the connecting rod has the seat end faces of the first connecting seat 21 on both sides and the connecting rod 1 provided with adaptive ribs 4. The setting of the corresponding ribs 4 on both sides of the locking ring 3 on the connecting rod 1 can form an effective activity space for the locking ring 3 on the connecting rod 1, which can facilitate the rotation and adjustment of the locking ring 3 and effectively prevent the locking ring 3 from falling off or being lost. In addition, the ribs 4 on the seat end faces of the first connecting seat 21 can be adapted to the specific wall thickness of the connected pipe 100 according to actual usage requirements and the corresponding thread structure 211, thereby further avoiding unnecessary damage to the pipe 100 and its connecting part 2 structure due to excessive rotation and adjustment of the locking ring 3, thereby improving the stability and efficiency of the connection process.

[0032] The rod structure 11 between the ribs 4 on both sides of the connecting rod 1 is made of transparent material. Figure 1 As shown in the figure, the rod structure 11 made of transparent material on the connecting rod can facilitate observation of the connection between the connecting parts 2 at both ends of the connecting rod 1 and the pipeline 100, and can also observe the circulation of the liquid in the pipeline 100, which is convenient for later maintenance operations such as finding and unblocking blockages in the pipeline 100.

[0033] See also Figure 3-4The rod structure 11 between the ribs 4 on both sides of the connecting rod 1 is installed on the connecting rod 1 through a detachable structure to form a second connecting rod. The corresponding positions of the connecting rods 1 on both sides of the second connecting rod 11 are provided with plug-in parts 5 that are adapted to the rod body of the second connecting rod 11. The two ends of the second connecting rod 11 are plugged into the plug-in parts 5 of the connecting rod 1 to fix it. The second connecting rod 11 can be installed and disassembled through the plug-in parts 5 provided at the corresponding positions of the connecting rod 1, and the adaptation length of the second connecting rod 11 can be selected according to the specific connection requirements and the distance between the pipes 100 connected on both sides, thereby further improving the applicability and flexibility of use of this type of quick connector for pipes 100. In addition, the rod structure 11 of the second connecting rod 11 can also be used or removed by selecting corresponding materials such as transparent materials according to usage requirements. Figure 4 The bellows 111 structure shown in the figure is adapted to meet different usage requirements and usage environments.

[0034] The plug-in portion 5 includes a first plug 51 and a second plug 52 embedded in the first plug 51. A slot 53 is provided between the first plug 51 and the second plug 52, and the second plug 52 extends in a direction away from the connecting rod 1 with a redundant length. The plug-in portion 5 also includes a clamp 54 adapted to the second connecting rod 11. The clamp 54 is placed on one side of the first plug 51 and surrounds the outer periphery of the second plug 52. For details, see Figure 4 As shown, when the second connecting rod 11 is installed, the two ends of its rod body can be respectively inserted into the slot 53 between the first plug 51 and the second plug 52, and the first plug 51 is placed on the outside of the rod body of the second connecting rod 11, while the second plug 52 is placed inside the rod body of the second connecting rod 11 and fits with its inner wall. After the plugging is completed, the two ends of the rod body of the second connecting rod 11 can be fastened to the relative positions of the second plug 52 by the clamp 54. The structural setting of the plug-in part 5 cooperates with the design of the first plug 51 and the second plug 52 and the matching slot 53 therebetween. The arrangement can further improve the adaptability and fit between the connecting rod 1 and the two ends of the second connecting rod 11, so that the second connecting rod 11 connected to the connecting rod 1 is not prone to deviation and shaking, and the redundant length of the second plug 52 and the clamp 54 surrounding it can further improve the connection stability with the two ends of the second connecting rod 11. At the same time, the structural arrangement of this plug-in part 5 is simple and stable, which is convenient for installation, disassembly and replacement operations. Combined with the rod structure of the second connecting rod 11, it can improve flexibility and convenience during use.
