[0039] See also Figure 1 The present invention provides a PE pipe socket connection structure, including a socket end 1 and a spigot end 2 respectively arranged on different pipe bodies, and the socket end 1 and the spigot end 2 are respectively connected to the corresponding pipe bodies in one piece. The outer diameter of the socket end 1 is larger than the outer diameter of the pipe body, and the inner diameter of the socket end 1 is consistent with the outer diameter of the spigot end 2. A limiting portion 3 is provided on the outer wall of the spigot end 2, and the limiting portion 3 is formed as an outward protrusion, so as to limit the length of the spigot end 2 and form a plug-in limit. A sealing protrusion 4 can also be provided on the outer wall of the spigot end 2, and the sealing protrusion 4 is arranged around the spigot end 2. After the spigot end 2 and the socket end 1 are plugged in, the sealing protrusion 4 is located in the socket end 1, which plays a role in sealing and increasing the stability of the connection.

[0040] See also Figure 1 In one embodiment of the present invention, an outer guide portion 5 is provided at one end of the socket end 1 away from the pipe body, and the inner wall of the guide portion is inclined, that is, the inner diameter of the outer end is larger than the inner diameter of the inner end, so that the plug-in processing of the socket end 2 and the socket end 1 can be completed more conveniently. The position where the outer guide portion 5 is connected to the socket end 1 forms an annular groove transition, so that the outer guide portion 5 can be closely fitted with the limit portion 3 of the socket end 2 after connection to ensure the connection sealing effect. An inner guide portion can be provided at one end of the socket end 2 away from the pipe body, and the size of the outer end of the inner guide portion (the end away from the pipe body) is smaller than the size of the inner end, so that the plug-in processing of the socket end 2 and the socket end 1 can be completed more conveniently. The length of the socket end 2 can be slightly longer than the length of the socket end 1, so that after the plug-in is completed, the inner guide portion can be squeezed by the inner wall of the pipe body to be closer to the inner wall of the socket end 2 (the outer end of the inner guide portion is at the transition position between the socket end 2 and the pipe body or extends into the pipe body), so as to ensure the connection effect of the two sections of the pipe body.

[0041] See also Figure 2-8The present invention is an automatic plug-in device for the above-mentioned PE pipe socket connection structure, including a base 6, a fixed frame 7, a fixed support 8, a pressure block 1 9, a movable frame 10, a movable support 11, a pressure block 2 14 and a linear drive component. The base 6 is used as a basic structure. A handle may be provided on the side of the base 6 to facilitate the movement of the base 6. An operation panel is provided on the base 6, and a control button for controlling the start and stop of the equipment is provided on the operation panel. The control buttons include start and stop buttons and an emergency stop button of different drive components. The operation panel may include a display screen for displaying and adjusting the control program.

[0042] See also Figure 2 In one embodiment of the present invention, the fixing frame 7 is fixedly arranged on the base 6; the fixing frame 7 may include a horizontal plate and a vertical plate that are fixedly connected. The fixed support 8 is fixedly arranged on the horizontal plate of the fixing frame 7, and a clamping groove 13 is provided on the top surface of the fixed support 8; the pressure block 19 is arranged above the fixed support 8, and a clamping groove 13 is provided on the bottom surface of the pressure block 19; a linear drive component may be provided on the vertical plate to drive the pressure block 19 to move linearly up and down. The cross-section of the clamping groove 13 is semicircular, and the size of the clamping groove 13 is consistent with the diameter of the tube body, and the clamping grooves 13 on the fixed support 8 and the movable support 11 are on a straight line. That is, the pressure block 19, the fixed support 8 and the pressure block 2 14 and the movable support 11 cooperate to clamp and fix two sections of the tube body respectively.

[0043] See also Figure 2 In one embodiment of the present invention, the movable frame 10 is slidably disposed on the base 6 and connected to a linear drive assembly 12; the movable frame 10 can be slidably connected to the base 6 via a slide rail structure. Specifically, a slide rail is fixedly disposed on the base 6, and a slider that cooperates with the slide rail is fixedly disposed on the bottom surface of the movable frame 10. The linear drive assembly 12 is used to drive the movable frame 10 to move linearly so as to approach or move away from the fixed frame 7.

[0044] See also Figure 2In one embodiment of the present invention, the movable frame 10 may include a horizontal plate and a vertical plate fixedly arranged at right angles, the movable support 11 is fixedly arranged on the horizontal plate of the movable frame 10, and a clamping groove 13 is provided on the top surface of the movable support 11; the pressure block 2 14 is located directly above the movable support 11, and a clamping groove 13 is provided on its bottom surface; a linear drive component is fixedly arranged on the vertical plate to drive the pressure block 2 14 to move linearly up and down. The linear drive component can be a cylinder structure, a screw drive structure or a linear motor, etc. As an example, two sets of linear drive components 2 15 are respectively used to drive the pressure block 1 9 and the pressure block 2 14 to move up and down; the linear drive component 1 12 and the linear drive component 2 15 are both cylinder drive structures.

[0045] See also Figure 3-4 In one embodiment of the present invention, the movable support 11 and the pressure block 14 are respectively provided with limiting notches 16, and the two limiting notches 16 can enclose a limiting cavity that matches the outer diameter of the socket end 1. By setting the limiting cavity, the freedom of movement of the pipe body can be limited, and the stability of the pipe body can be ensured, thereby ensuring that the socket end 1 can be stably plugged into the socket end 2 when the movable frame 10 moves. The length dimension of the limiting cavity is smaller than the length dimension of the socket end 1. In this way, a portion of the socket end 1 can be slightly exposed, and while the stability of the socket end 1 during the plug-in process is ensured by the limiting cavity, the leaking portion of the socket end 1 can undergo a certain deformation, which can make it easier to dock and plug with the socket end 2.

[0046] See also Figure 3-4 as well as Figure 7 In one embodiment of the present invention, the length dimension of the movable support 11 is greater than the length dimension of the pressure block 14, so that the pipe body where the socket end 1 is located can be effectively supported at the bottom. A support plate 17 is fixedly arranged on the base 6, and a V-shaped support notch is opened at the top of the support plate 17, and the height position of the support notch is consistent with the height position of the clamping groove 13 on the fixed support 8. By providing the support plate 17 and cooperating with the fixed support 8, the pipe body where the socket end 2 is located is supported, so that it can maintain horizontal stability during the plug-in process, ensure the plug-in effect, and avoid the pipe body being difficult to align during the plug-in process due to bending.

[0047] See also Figure 8In one embodiment of the present invention, a roller 18 is provided in the movable support 11, and the roller 18 is connected to the rotation power source. The roller 18 can be located directly below the clamping groove 13 and can contact the surface of the tube body located in the clamping groove 13. The roller 18 is used to drive the tube body to move, so that the socket end 1 can be in the limiting cavity, and the tube body is prevented from extending out of the support more and bending during the insertion process due to its insufficient radial strength. Preferably, the rotation direction of the roller 18 is inclined to the tube body, so that the tube body can be driven to move while promoting its rotation, so that the tube body can be centered and avoid sagging during the insertion process of the socket end 1 and the socket end 2. The side of the roller 18 is provided with bristles, and the contact between the bristles and the tube body promotes the movement of the tube body. Avoid the roller 18 with higher hardness directly contacting to produce higher pressure and negatively affect the tube body, including that the bristles will not cause destructive effects on the tube body after the insertion is completed. The bristles can also be replaced by a flexible layer.

[0048] Working principle of the present invention:

[0049] Initially, the movable frame 10 is separated from the fixed frame 7, and the pressure blocks 1 9 and 2 14 are in a high position. When in use, the pipe body where the socket end 1 and the plug end 2 are located is placed in the clamping grooves 13 on the movable support 11 and the fixed support 8, respectively, and then the equipment is started. At this time, the pressure blocks 1 9 and 2 14 are synchronously lowered to contact and cooperate with the fixed support 8 and the movable support 11, respectively, and the clamping grooves 13 thereon form clamping cavities for defining two sections of the pipe body. Then, the linear drive assembly 1 12 drives the movable frame 10 to move toward the fixed frame 7, driving the movable support 11, the pipe body, etc. thereon to move together. In this process, the socket end 1 is docked with the plug end 2. Since the freedom of the socket end 1 to move to the left is locked by the clamping groove 13 (limiting cavity), and the freedom of the spigot end 2 to move to the right is locked by the clamping groove 13 and the limiting part 3 on the spigot end 2, after the movable frame 10 drives the movable support 11 to move to the specified position, the socket end 1 and the spigot end 2 complete the plug-in action. Then, the pressing block 1 9 and the pressing block 2 14 are reset upward, and after the plug-in completed pipe body is removed, the movable frame 10 is reset. The placement and removal of the pipe body can be performed manually, or by setting up corresponding loading and unloading structures such as manipulators.

[0050] After the pipe body is placed on the support platform, if its plug-in end extends too much, it will lack effective support and be easily bent in the radial direction, especially during the docking process of the socket end 1 and the plug end 2, it will be slightly bent downward due to gravity. If it extends too much, the bending amount will become larger. During the docking process, it is very easy for the socket end 1 and the plug end 2 to bend downward under pressure, resulting in poor plug-in quality, or even failure to successfully complete the plug-in action. Therefore, a roller 18 structure is provided to avoid this situation. The pressure block 1 9 and the pressure block 2 14 are synchronously lowered to contact and cooperate with the fixed support platform 8 and the movable support platform 11 respectively, and the clamping grooves 13 thereon form clamping cavities for limiting the two sections of the pipe body respectively. After this action is completed, the roller 18 structure can be started to rotate, prompting the pipe body where the socket end 1 is located to move to the left, so that the socket end 1 is in the limiting cavity, so that the limiting cavity can give full play to the limiting support effect of the socket end 1 during the plug-in process. Similarly, a corresponding roller 18 structure may be provided in the fixed support 8 to drive the tube body where the socket end 2 is located to move to the right, and the limit position of the rightward movement of the tube body where the socket end 2 is located is limited by the limit portion 3 on the socket end 2. The movement of the tube body in this process can be achieved by setting the size of the clamping groove 13 to be slightly larger than the size of the tube body, so that the clamping structure composed of the support, the pressure block, etc. does not limit the limited movement of the tube body. The roller 18 structure drives the tube body to move axially, so that the socket end 1 can be stably located in the limit cavity, and the limit portion 3 of the socket end 2 is close to the end of the fixed support 8, so that the two sections of the tube body will not extend too much from the support, ensuring that stable support is provided to the tube body, avoiding bending of the tube body, and ensuring the quality and stability of plug-in.
