[0003] In order to avoid blockage caused by residual substances, the foaming material gun often needs to be cleaned inside after use. Most of the existing foaming material guns are fixed by means of threaded connection between the gun body and the gun barrel. When the threaded connection is too tight, it is time-consuming and laborious to disassemble and assemble, and it is not simple and convenient enough. When it is too loose, it is easy to affect the tightness of the connection, resulting in raw material leakage. In view of this, we propose a connection structure of an EPP material gun to solve the above problems. Content of the Utility Model

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1 , an EPP material gun connection structure, including a material gun body 1 and a feed pipe 20. The material gun body 1 further includes a pipe body 101 and a gun body 102, and a connection component is provided between the pipe body 101 and the gun body 102.

[0026] Please refer to Figure 2 , wherein the connection component includes a connecting sleeve 3 fixedly installed on the surface of the gun body 102, a connecting block 4 fixedly installed on the surface of the pipe body 101 and located inside the connecting sleeve 3, and a limit component for limiting the connecting block 4 is further provided inside the connecting sleeve 3.

[0027] Please refer to Figure 3 and Figure 5 , the limit component includes two installation grooves 5 opened on the inner wall of the connecting sleeve 3, two limit grooves 6 opened on the surface of the connecting block 4, an arc-shaped limit plate 7 provided on the inner wall of the limit groove 6, two sleeves 8 fixedly installed on the surface of the connecting sleeve 3, a movable rod 9 rotatably installed on the surface of the limit plate 7 and extending into the sleeve 8, a fixed block 11 rotatably installed on the surface of the movable rod 9, a slide block 19 fixedly installed on the surface of the fixed block 11 and extending into the inner wall of the sleeve 8, a return spring 12 fixedly installed between the fixed block 11 and the connecting sleeve 3, two slots 13 opened on the surface of the sleeve 8, and two limit rods 14 fixedly installed on the surface of the movable rod 9 and extending into the slots 13.

[0028] Wherein, one end of the movable rod 9 away from the connecting sleeve 3 is located outside the sleeve 8. A pull block 10 is also fixedly installed at the end of the movable rod 9 located outside the sleeve 8. The movable rod 9 is rotationally connected to the outer wall of the limiting plate 7 through a bearing. The return spring 12 is located outside the movable rod 9.

[0029] In addition, by adjusting the position of the limiting plate 7 to insert it into the limiting groove 6, the connecting block 4 can be limited, thereby completing the installation of the pipe body 101 and the gun body 102. On the contrary, pulling the limiting plate 7 to move it into the installation groove 5 can disassemble the pipe body 101 and the gun body 102. At the same time, the position of the limiting plate 7 can be limited by the limiting rod 14. Compared with the threaded connection method, this structure is simple and convenient to operate, time-saving and labor-saving, and greatly improves the disassembly, assembly, maintenance or cleaning efficiency of the EPP material gun.

[0030] Please refer to Figure 3 , in this embodiment, a chute 18 is further opened on the inner wall of the sleeve 8. One end of the slider 19 extending into the inner part of the sleeve 8 is slidably connected to the inner wall of the chute 18.

[0031] Wherein, a bearing is also installed on the inner wall of the fixed block 11. The fixed block 11 is rotationally connected to the outer wall of the movable rod 9 through a bearing. The chute 18 and the slider 19 are provided for guiding and positioning the fixed block 11, so that the fixed block 11 does not rotate when the movable rod 9 rotates, thereby ensuring the stability of the return spring 12.

[0032] Please refer to Figure 5 and Figure 6 , in this embodiment, the limiting rod 14 is clamped on the inner wall of the slotted groove 13. The installation groove 5 and the limiting groove 6 are both semi-circularly arranged. The limiting plate 7 is slidably connected to the inner walls of the installation groove 5 and the limiting groove 6.

[0033] Wherein, the slotted groove 13 is a horizontally U-shaped arrangement. When the limiting rod 14 is clamped with the horizontal part below the slotted groove 13, at this time, the limiting plate 7 is located inside the limiting groove 6. When the limiting rod 14 is clamped with the horizontal part above the slotted groove 13, at this time, the limiting plate 7 is located inside the installation groove 5, thus facilitating the connection of the pipe body 101 and the gun body 102.

[0034] Please refer to Figure 3 , in this embodiment, a connection groove is opened on one side of the pipe body 101 close to the gun body 102. A plug-in block 15 extending into the connection groove is fixedly installed on one side of the gun body 102 close to the pipe body 101. A sealing sleeve 16 is also fixedly installed on the inner wall of the connection groove. The plug-in block 15 is slidably connected to the inner wall of the sealing sleeve 16. Two positioning grooves 17 are also opened on one side of the connecting sleeve 3. Two positioning blocks 2 extending into the positioning grooves 17 are fixedly installed on the surface of the connecting block 4.

[0035] Among them, by providing the plug-in block 15, the connecting groove and the sealing sleeve 16, the sealing performance when the pipe body 101 and the gun body 102 are connected is improved.

[0036] In addition, by providing the positioning block 2 and the positioning groove 17, after the pipe body 101 and the gun body 102 are connected, the limiting plate 7 and the limiting groove 6 can be accurately aligned, further improving the convenience of disassembling and assembling the EPP material gun.

[0037] When this embodiment is in use, during disassembly, rotate the movable rod 9 so that the limiting rod 14 is located in the vertical part of the slot 13, and then pull up the movable rod 9 to make the limiting plate 7 disengage from the limiting groove 6. When the limiting plate 7 completely moves into the installation groove 5, rotate the movable rod 9 so that the limiting rod 14 is stuck into the horizontal part of the slot 13. At this time, the limiting plate 7 is limited, and at the same time, the limiting plate 7 no longer limits the connecting block 4. At this time, the pipe body 101 can be directly disassembled;

[0038] When installation is required, align the positioning block 2 with the positioning groove 17, and then connect the pipe body 101 and the gun body 102. After the connection is completed, repeat the above operation steps. When the limiting rod 14 is no longer limited by the slot 13, the limiting plate 7 will automatically snap into the limiting groove 6 under the elastic force of the return spring 12, thereby completing the limitation of the connecting block 4, and then completing the connection of the pipe body 101. Subsequently, continue to rotate the movable rod 9 so that the limiting rod 14 is stuck into the horizontal part of the slot 13, and the installation of the pipe body 101 is completed. The operation is simple and convenient, time-saving and labor-saving, greatly improving the efficiency of disassembling, assembling, maintaining or cleaning the EPP material gun.
