DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4As shown, a square laser cutting machine head nozzle includes a nozzle 1, a discharge port 2 is provided at the lower end of the nozzle 1, an adjustment structure 3 is installed at the rear end of the nozzle 1, the adjustment structure 3 includes a fixing part 4, a bidirectional screw 5 is arranged inside the fixing part 4, sliders 6 are threadedly arranged on the outer walls on both sides of the bidirectional screw 5, connecting plates 7 are installed at the front ends of the two groups of sliders 6, a limiting groove 8 is provided at the front end of the fixing part 4, an adjustment plate 10 is installed on one side of the front end of the connecting plate 7 passing through the limiting groove 8, stabilizing grooves 9 are provided on both sides of the nozzle 1, and one side of the adjustment plate 10 leads to the interior of the nozzle 1.

[0023] In this embodiment, a protective structure 11 is provided on both sides of the nozzle 1, and the protective structure 11 includes a protective cover 12. A screw 13 is provided at the upper end of the protective cover 12. Threaded holes 14 are opened on both sides of the upper end of the nozzle 1, and the lower end of the screw 13 passes through the protective cover 12 and enters into the interior of the threaded hole 14.

[0024] The protective cover 12 protects and blocks the connecting plate 7 and the adjusting plate 10 , so that when the operator touches the nozzle 1 , burns can be avoided. The threaded hole 14 facilitates the entry and installation of the screw 13 .

[0025] In this embodiment, the upper corners of the two groups of adjustment plates 10 near one end are arc-shaped.

[0026] The upper corner of one end of the adjusting plate 10 is arc-shaped, which can better facilitate the delivery of laser light.

[0027] In this embodiment, the upper end of the outer wall of the nozzle 1 is provided with a mounting thread.

[0028] In this embodiment, a reinforcement groove 16 is opened at the front end of the stabilizing groove 9 , and a stabilizing plate 15 is fixedly provided at the front end of one side of the protective cover 12 , and the stabilizing plate 15 enters into the reinforcement groove 16 .

[0029] The reinforcement groove 16 facilitates the entry of the stabilizing plate 15 , thereby enhancing the stability of the installation of the protective cover 12 .

[0030] In this embodiment, an isolation cavity 17 is formed on a side of the protective cover 12 close to the nozzle 1 .

[0031] The isolation chamber 17 is used to place the protective cover 12 .

[0032] In this embodiment, the connecting plate 7 is located inside the isolation cavity 17 , and the upper and lower ends of the connecting plate 7 are not in contact with the inner walls of the upper and lower ends of the protective cover 12 .

[0033] The upper and lower ends of the connecting plate 7 do not contact the inner walls of the upper and lower ends of the protective cover 12, so that direct transfer of heat from the connecting plate 7 can be avoided.

[0034] It should be noted that the utility model is a square laser cutting machine head nozzle. When the size of the light beam needs to be adjusted, the bidirectional screw rod 5 is rotated to move the two sets of sliders 6, thereby driving the connecting plate 7 to move, so that the adjustment plate 10 is located inside the stabilizing groove 9 and moves, thereby limiting the position of the laser beam ejection, and achieving the purpose of quick adjustment;

[0035] The protective cover 12 is put on both sides of the nozzle 1, and the screws 13 are passed through the protective cover 12 and finally enter into the threaded hole 14 to install the protective cover 12. When the operator touches the nozzle 1 with his limbs, he will not directly contact the adjustment plate 10 or the connecting plate 7, which can avoid burns and better achieve the purpose of protection.
