[0002] High-pressure water jet cutting machines, also known as water cutters or water jet cutting machines, are industrial equipment that uses high-pressure water flow or water jet for cutting. They are widely used in the field of material processing. High-pressure water jet cutting machine nozzles are easily damaged by impacts during use. Therefore, protective structures are needed to protect the nozzles during operation. Existing anti-collision protective nozzles for high-pressure water jet cutting machines have at least the following drawbacks: 1. Existing anti-collision protective nozzles for high-pressure water jet cutting machines do not easily provide cushioning protection for multiple points within the nozzle itself; 2. The protective structure of existing anti-collision protective nozzles for high-pressure water jet cutting machines has poor stability and is difficult to install and disassemble. Therefore, we have introduced a new anti-collision protective nozzle for high-pressure water jet cutting machines. Utility Model Content

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A collision-resistant nozzle for a high-pressure water jet cutting machine includes a connecting pipe 1, a connector 2 fixedly connected to the upper end of the connecting pipe 1, a nozzle body 7 fixedly connected to the upper end of the connector 2, and a plurality of fixing blocks 3 fixedly connected in a ring array on the upper part of the outer surface of the connecting pipe 1. Each of the fixing blocks 3 has a protective component 6 fixedly connected to its upper end. Each of the fixing blocks 3 has a first connecting screw groove 5 and two connecting holes 4. The plurality of first connecting screw grooves 5 are respectively located between a plurality of groups of two first connecting holes 4 in a transverse direction.

[0027] In this embodiment, the protective component 6 includes a connecting structure 61. A fixing screw 62 is inserted through the middle of the upper end of the connecting structure 61. A support structure 63 is fixedly connected to the right end of the fixing screw 62. Protective plates 64 are sleeved on both the upper and lower ends of the support structure 63. Two positioning screws 65 are inserted through the ends of the two protective plates 64 that do not contact the support structure 63. The connecting structure 61 is fixedly connected to the fixing block 3. The connecting structure 61 includes a connecting block 611. Two insert rods 613 are fixedly connected to the lower end of the connecting block 611. The right side of the outer surface of the connecting block 611 is fixedly connected to... A telescopic rod 612 is attached, with a round block 614 fixedly connected to the right end of the telescopic rod 612. A spring 615 is sleeved on the right side of the outer surface of the telescopic rod 612. A connecting block 611 is sleeved with a fixing screw 62. Several sets of two horizontal positioning screws 65 pass through several protective plates 64 and are inserted into several sets of two horizontal No. 2 connecting screw grooves 634. Several sets of two horizontal insert rods 613 are inserted into several sets of two horizontal connecting holes 4. Several fixing screws 62 pass through several connecting structures 61 and are inserted into several No. 1 connecting screw grooves 5.

[0028] The above scheme protects the connecting pipe 1, connector 2, and nozzle body 7 during use by using the protective component 6. The two insert rods 613 are respectively inserted and connected to the two connecting holes 4, and the fixed screw 62 passes through the connecting structure 61 and is inserted and connected to the first connecting screw groove 5 to position the protective component 6. The spring 615 and the telescopic rod 612 together buffer and protect the two protective plates 64 from impact, thereby improving stability.

[0029] In this embodiment, the support structure 63 includes a connecting ring 631. A connecting screw 632 is inserted and connected to the right side of the outer surface of the connecting ring 631. Two support rods 633 are fixedly connected to both the upper and lower ends of the connecting ring 631. The ends of the two sets of horizontal support rods 633 that do not contact the connecting ring 631 are provided with a second connecting screw groove 634. The two sets of horizontal support rods 633 are respectively inserted and connected to two protective plates 64. Several connecting screws 632 pass through several connecting rings 631 and are inserted and connected to several round blocks 614.

[0030] The above scheme fixes the connection between the support structure 63 and the connecting structure 61 by connecting screw 632 passing through connecting ring 631 and inserting into round block 614. The two protective plates 64 are respectively sleeved with two sets of two horizontal support rods 633, and the positions of the two protective plates 64 are respectively positioned by two sets of two horizontal positioning screws 65 passing through the two protective plates 64 and inserting into two sets of two horizontal No. 2 connecting screw grooves 634. The two protective plates 64 are easy to install, disassemble and replace.

[0031] It should be noted that this utility model is an anti-collision protective nozzle for a high-pressure waterjet cutting machine. During use, the inserts 613 on several protective components 6 are inserted into several connecting holes 4, and then several fixing screws 62 pass through several connecting structures 61 and are inserted into several first-order connecting screw grooves 5, thus completing the positioning of the protective components 6. Several connecting screws 632 pass through several connecting rings 631 and are inserted into several round blocks 614, ensuring a stable connection between the supporting structures 63 and the connecting structures 61. Then, several sets of two longitudinal protective plates 64 are respectively fitted onto two sets of two transverse support rods 633, and then two sets of two transverse positioning screws 65 pass through two... The protective plates 64 are inserted and connected to two sets of transverse No. 2 connecting screw grooves 634, thereby fixing the position of the two protective plates 64. This connection method makes the installation and disassembly of the two protective plates 64 very convenient, facilitating subsequent replacement and maintenance. During the operation of the nozzle, several protective components 6 together form a protective barrier, which plays an anti-impact protection role for the connecting pipe 1, the connecting head 2 and the nozzle body 7 at multiple angles. When the two sets of longitudinal protective plates 64 are impacted, the springs 615 and the telescopic rods 612 on the several protective components 6 will work together. Through the elastic deformation of the springs 615 and the extension and retraction of the telescopic rods 612, the impact force is buffered and dissipated, effectively reducing the impact of the impact, thereby improving the stability of the entire nozzle device during use.
