DETAILED DESCRIPTION

[0022] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a nozzle that is easy to connect, including an ink box 1, the ink box 1 is connected to an external tube 2, an ink outlet 3 is arranged on the side wall of the ink box 1, a nozzle 4 is arranged on the side of the ink outlet 3, the nozzle 4 is installed by pushing the nozzle 4 toward the ink outlet 3, an installation mechanism 5 is arranged on the ink outlet 3 and the nozzle 4, an installation groove 7 is opened on the nozzle 4, and a stabilizing mechanism 6 is arranged on the ink outlet 3 and the installation groove 7.

[0023] In this embodiment, a mounting mechanism 5 is provided on the ink outlet 3 and the nozzle 4. The limit can be automatically released by the arc surface of the clamping block 52 in the mounting mechanism 5 being squeezed by the ink outlet 3. The nozzle 4 can be easily installed by clamping the clamping block 52 in the clamping groove 53. At the same time, the elastic plate 51 drives the clamping block 52 to release the limit, so that the nozzle 4 can be disassembled and replaced conveniently.

[0024] In this embodiment, a stabilizing mechanism 6 is provided on the ink outlet 3 and the mounting groove 7. By squeezing one end of the arc plate 65 through the fixing block 62 in the stabilizing mechanism 6, the other end of the arc plate 65 can be snapped into the interior of the limiting groove 66. By being snapped into place by the fixing block 62, the nozzle 4 can be installed more stably.

[0025] The above-mentioned installation mechanism 5 includes an elastic plate 51, which is fixedly installed on the outer wall of the nozzle 4. A block 52 is fixedly installed on the outer wall of the elastic plate 51. The block 52 on the outer wall of the elastic plate 51 is driven by the nozzle 4 to move toward the ink outlet 3 for installation. The block 52 is set to be arc-shaped. The edge of the ink outlet 3 squeezes the arc surface of the block 52, which can make the block 52 drive the elastic plate 51 to deform and release the limit, so that the block 52 is convenient to be connected to the inside of the slot 53, thereby completing the installation of the nozzle 4. A slot 53 is provided on the outer wall of the ink outlet 3. The slot 53 is adapted to the size of the block 52 and is located on the side of the block 52.

[0026] The above-mentioned stabilizing mechanism 6 includes a mounting rod 61, which is fixedly mounted on the outer wall of the ink outlet 3. The mounting rod 61 is arranged in a bent shape. A fixing block 62 is fixedly mounted on the end of the mounting rod 61. Two groups of fixing blocks 62 are arranged in total, and the two groups of fixing blocks 62 are symmetrically arranged with the center line in the transverse direction of the ink outlet 3 as the symmetry axis. A rotating rod 63 is rotatably connected to the inner wall of the mounting groove 7. The outer wall of the rotating rod 63 is fixedly connected to one end of a torsion spring 64, and the other end of the torsion spring 64 is elastically connected to the inner wall of the mounting groove 7. The elastic force of the torsion spring 64 can make the arc The plate 65 is rotated and reset to release the limit, which makes it convenient to disassemble and replace the nozzle 4. An arc plate 65 is fixedly sleeved on the outer wall of the rotating rod 63. One end of the arc plate 65 is squeezed by the fixed block 62 to make the arc plate 65 rotate around the rotating rod 63. The arc plate 65 is arranged in an arc shape. The end of the arc plate 65 is snapped into the inside of the limit groove 66 to make the nozzle 4 be installed more firmly. The arc plate 65 is located inside the installation groove 7. A limit groove 66 is provided on the outer wall of the fixed block 62. The limit groove 66 is located on the side of the arc plate 65.

[0027] In this embodiment, when the nozzle 4 needs to be installed, the nozzle 4 is pushed toward the ink outlet 3, and then the nozzle 4 drives the block 52 on the outer wall of the elastic plate 51 to move toward the ink outlet 3, and then the edge of the ink outlet 3 squeezes the arc surface of the block 52, so that the block 52 drives the elastic plate 51 to deform and the limit is released, and finally the block 52 is connected to the inside of the slot 53 by the elastic force of the elastic plate 51, and the installation of the nozzle 4 is completed. During the installation process, the fixing block 62 moves into the inside of the installation slot 7, and then the fixing block 62 is fixed. The block 62 squeezes one end of the arc plate 65, causing the arc plate 65 to rotate around the rotating rod 63, and then the other end of the arc plate 65 is clamped into the inside of the limiting groove 66, and is clamped by the fixing block 62 on the ink outlet 3, so that the nozzle 4 can be installed more firmly. When the nozzle 4 needs to be disassembled, the elastic plate 51 is moved to drive the clamping block 52 to release the limit, and then the nozzle 4 is pulled away from the ink outlet 3. The elastic force of the torsion spring 64 causes the arc plate 65 to rotate and reset to release the limit, thereby facilitating the disassembly and replacement of the nozzle 4.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
