[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 3 As shown, a structure for rapid positioning of a nozzle comprises a base plate 1; a shell 3 is installed on the side end of the base plate 1; a positioning plate 2 is installed on the side end of the shell 3; a positioning magnet plate is fixedly connected to one end of the positioning plate 2, and the positioning magnet plate is connected to the base plate 1; a nozzle body 5 is installed inside the shell 3; a limiting unit is provided on the base plate 1.

[0021] Before work, the positioning plate 2 is installed to the side end of the base plate 1. The positioning plate 2 is adsorbed to the side end of the base plate 1 by the magnetic attraction of the positioning magnet plate, so that the positioning plate 2 can be easily installed and disassembled on the base plate 1, which is much more convenient than the traditional bolt installation and disassembly, and avoids the positioning plate 2 from sliding left and right during the process. The positioning pressure rod 8 is connected to the positioning plate 2, and the positioning pressure plate 6 is made to slide in the direction of the positioning plate 2 through the spring elasticity of the telescopic rod 7, so that the positioning pressure rod 8 presses the positioning plate 2 on the base plate 1, thereby limiting the position of the positioning plate 2 and avoiding the position of the positioning plate 2 from sliding during work.

[0022] The limiting unit includes a telescopic rod 7; the side end of the base plate 1 is equipped with a telescopic rod 7; the internal fixing spring of the telescopic rod 7; the side end of the telescopic rod 7 is connected to a positioning pressure plate 6; the bottom end of the positioning pressure plate 6 is fixed with a positioning pressure rod 8, and the bottom end of the positioning pressure rod 8 is equipped with a positioning plate 2.

[0023] The positioning plate 2 is adsorbed to the side end of the base plate 1 by the magnetic attraction of the positioning magnet plate, so that the positioning plate 2 can be easily installed and disassembled on the base plate 1, and the positioning pressure rod 8 is connected to the positioning plate 2. The spring elasticity of the telescopic rod 7 makes the positioning pressure plate 6 slide in the direction of the positioning plate 2, so that the positioning pressure rod 8 presses the positioning plate 2 on the base plate 1, thereby limiting the position of the positioning plate 2 and avoiding the position of the positioning plate 2 from sliding during operation.

[0024] A positioning hole is formed inside the positioning pressure plate 6 ; a positioning screw 10 is threadedly connected inside the positioning hole; and a rotating rod 9 is fixedly connected to the top end of the positioning screw 10 .

[0025] When the positioning pressure rod 8 is installed and fixed to the positioning plate 2, the rotating rod 9 can be rotated to rotate the positioning screw 10. The positioning screw 10 is threadedly connected to the positioning hole. The positioning screw 10 is rotated to the bottom side end of the base plate 1. The bottom end of the positioning screw 10 is in contact and squeezed with the base plate 1, thereby limiting the position of the positioning pressure plate 6 to avoid the positioning pressure plate 6 from sliding randomly during operation.

[0026] An adjusting slot 13 is formed at the bottom end of the positioning plate 6 ; a telescopic rod 7 is slidably connected to the bottom end of the adjusting slot 13 .

[0027] Before the installation of the positioning plate 2, the positioning pressure plate 6 can be slid and adjusted, and the telescopic rod 7 slides on the adjustment slide groove 13, so that the positioning pressure plate 6 can slide on the telescopic rod 7, so that the position of the positioning pressure plate 6 will not affect the installation work of the positioning plate 2. After the positioning plate 2 is installed, the positioning pressure plate 6 is slid to the top of the positioning plate 2, and the positioning plate 2 is limited by the positioning pressure rod 8.

[0028] A retaining plate 11 is fixedly connected to the side end of the telescopic rod 7 ; a limiting screw 12 is threadedly connected to the retaining plate 11 , and the bottom end of the limiting screw 12 is connected to the bottom plate 1 .

[0029] When the position of the telescopic rod 7 needs to be adjusted or disassembled, the disassembly limit screw 12 is rotated to contact the fixing plate 11, so that the telescopic rod 7 can be disassembled, and the positioning pressure plate 6 can also be disassembled together and separated from the base plate 1.

[0030] The housing 3 is provided with a plurality of positioning bolts 4 ; the bottom plate 1 is provided with a plurality of positioning plates 2 and a nozzle body 5 .

[0031] When it is necessary to simply observe the condition of the nozzle body 5, the positioning bolt 4 can be rotated. The shell 3 is installed and fixed to the positioning plate 2 through multiple sets of positioning bolts 4. After rotating and removing the positioning bolts 4, the condition of the nozzle body 5 can be clearly observed, thereby determining whether to process the nozzle body 5, such as adding ink, cleaning, etc.

[0032] The working principle of the utility model is as follows: before work, the positioning plate 2 is installed to the side end of the base plate 1, and the positioning plate 2 is adsorbed to the side end of the base plate 1 by the magnetic attraction of the positioning magnet plate, so that the positioning plate 2 can be easily installed and removed on the base plate 1, which is much more convenient than the traditional bolt installation and removal, and the positioning plate 2 can be prevented from sliding left and right during the process. The positioning pressure rod 8 is connected to the positioning plate 2, and the positioning pressure plate 6 is made to slide in the direction of the positioning plate 2 by the spring elasticity of the telescopic rod 7, so that the positioning pressure rod 8 presses the positioning plate 2 on the base plate 1, thereby limiting the position of the positioning plate 2, and preventing the position of the positioning plate 2 from sliding during the work process; when it is necessary to simply observe the condition of the nozzle body 5, the positioning bolt 4 can be rotated, and the shell 3 is fixed to the positioning plate 2 by multiple sets of positioning bolts 4. After rotating and removing the positioning bolts 4, the condition of the nozzle body 5 can be clearly observed, so as to judge whether the nozzle body 5 should be processed, ink replenishment, cleaning, etc.; the positioning plate 2 is installed before When the position of the telescopic rod 7 needs to be adjusted or disassembled, the limiting screw 12 is rotated to contact the fixing of the fixing plate 11, so that the telescopic rod 7 can be disassembled, and the positioning pressure plate 6 can also be disassembled together with the bottom plate 1 to separate it from the bottom plate 1.

[0033] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
