[0028] Please see Figure 1-4 This utility model provides a technical solution:
[0029] A quick-drying glue gun for polyurethane foam sealant includes a gun body 1, a connecting tube 2 at the left end of the gun body 1, a connector 3 at the left end of the connecting tube 2, a connecting seat 4 at both the front and rear of the outer surface of the connector 3, an installation groove 5 at the left end of each of the two connecting seats 4, a locking hole 6 on the inner wall of each of the two installation grooves 5, and a glue injection device 7 movably installed inside the two installation grooves 5. An installation mechanism 8 is inserted and fixedly installed on the upper part of the outer surface of the connecting tube 2, an operating wrench 9 is provided on the left side of the outer surface of the gun body 1, an adjustment knob 10 is provided at the rear end of the gun body 1, and a handle 11 is provided on the lower right side of the gun body 1.
[0030] In this embodiment, the glue injection device 7 includes a glue injection tube 71. L-shaped blocks 72 are provided on the front right side and rear right side of the outer surface of the glue injection tube 71. Mounting blocks 73 are fixedly installed on the right ends of both L-shaped blocks 72. Springs 74 are fixedly installed inside the inner grooves of both mounting blocks 73. Driving blocks 75 are movably installed inside the inner grooves of both mounting blocks 73. A locking block 76 is fixedly installed at the end of each driving block 75 away from the spring 74. A sealing gasket 77 is provided on the right end of the glue injection tube 71, and a sealing groove 78 is provided on the left end of the connector 3. The glue injection tube 71 is movably locked inside the sealing groove 78 by the sealing gasket 77. The glue injection tube 71 is movably locked inside the two mounting grooves 5 by the mounting blocks 73. Two springs 74 are fixedly connected to the two driving blocks 75, and two locking blocks 76 are movably locked inside the two locking holes 6.
[0031] The above method allows for the following steps: When the glue injection tube 71 needs to be installed, the sealing gasket 77 at the right end of the glue injection tube 71 is aligned with the sealing groove 78 at the left end of the connector 3 and inserted. At the same time, the mounting blocks 73 on both sides of the glue injection tube 71 are aligned with the two mounting grooves 5 on the connector 3 and inserted. During the insertion into the mounting grooves 5, the inner wall of the mounting groove 5 will squeeze the locking block 76, causing the locking block 76 to compress the spring 74 through the driving block 75. When the locking block 76 moves to the position aligned with the locking hole 6, under the elastic action of the spring 74, the driving block 75 pushes the locking block 76 into the locking hole 6, thereby achieving the fixed installation of the glue injection tube 71. When disassembling, the glue injection tube 71 can be quickly disassembled by simultaneously squeezing the two locking blocks 76.
[0032] In this embodiment, the installation mechanism 8 includes a connecting pipe 81, a valve 82 is provided on the front of the outer surface of the connecting pipe 81, an installation sleeve 83 is provided on the upper end of the connecting pipe 81, and a threaded pipe 84 is provided in the middle of the lower inner wall of the installation sleeve 83; the threaded pipe 84 is connected to the interior of the connecting pipe 2 through the connecting pipe 81.
[0033] With the above solution: When installing the quick-drying glue cartridge, the connecting end of the quick-drying glue cartridge is inserted into the mounting sleeve 83, so that the connector at one end of the quick-drying glue cartridge is aligned with the internal threaded tube 84. Then, by rotating the quick-drying glue cartridge, the quick-drying glue cartridge can be installed quickly, making the installation process more stable. When in use, the glue flows from the connecting tube 2 into the connecting tube 81. Since the threaded tube 84 is connected to the inside of the connecting tube 2 through the connecting tube 81, the glue can continue to flow from the connecting tube 81 into the threaded tube 84 inside the mounting sleeve 83.
[0034] It should be noted that this utility model is a quick-drying glue gun for polyurethane foam sealant. During use, when installing the quick-drying glue cartridge, the connecting end of the cartridge is inserted into the mounting sleeve 83, aligning the connector at one end of the cartridge with the internal threaded tube 84. Then, by rotating the cartridge, the quick-drying glue cartridge is quickly installed onto the mounting sleeve 83 using the threaded connection, making the installation process more stable and effortless. When installing the injection tube 71, the sealing gasket 77 at the right end of the injection tube 71 is aligned with the sealing groove 78 at the left end of the connector 3 and inserted. Simultaneously, the mounting blocks 73 on both sides of the injection tube 71 are aligned with the two mounting grooves 5 on the connector 3 and inserted. During insertion, the inner wall of the mounting groove 5 will press against the locking block 76, causing the locking block 76 to move through the driving block 75. When the compression spring 74 moves the locking block 76 to the position aligned with the locking hole 6, the elastic action of the spring 74 drives the block 75 to push the locking block 76 into the locking hole 6. At this time, the glue injection tube 71 is movably locked inside the sealing groove 78 through the sealing gasket 77, and simultaneously locked inside the two mounting grooves 5 through the mounting block 73, thus achieving the fixed installation of the glue injection tube 71. During disassembly, by simultaneously squeezing the two locking blocks 76, the locking blocks 76 are compressed by the driving block 75 to release the spring 74, thereby causing the locking blocks 76 to disengage from the locking hole 6. Then, the mounting blocks 73 on both sides of the glue injection tube 71 are pulled out from the mounting grooves 5. Next, the sealing gasket 77 at the right end of the glue injection tube 71 is removed from the sealing groove 78, thus completing the disassembly of the glue injection tube 71, making installation and disassembly more convenient and labor-saving.
