[0033] As shown in the specific embodiments of the utility model, the utility model provides a kind of laser room protective door of impact resistance, including laser room frame 1; Figure 1 And Figure 2As shown, the driving mechanism 2 includes a fixed frame 201 fixed on the upper side in front of the laser room frame 1, and a driving motor 202 is fixedly arranged on the right side of the fixed frame 201. The output end of the driving motor 202 is fixedly connected with a lead screw 203. The lead screw 203 is driven to rotate by turning on the driving motor 202, and the rotation of the lead screw 203 drives the two side protection door bodies 6 to close and open to form automation.

[0034] As shown in Figure 2 , the lead screw 203 is provided in two groups, and the external threads of the two groups of lead screws 203 are opposite.

[0035] As shown in Figure 1 , Figure 3 and Figure 4 , the aluminum plate structure 604 is provided with double layers, and the first high-pressure laminated board 602 and the second high-pressure laminated board 605 are located in front and back of the aluminum plate structure 604. Through the aluminum alloy frame 601 and the first high-pressure laminated board 602 and the second high-pressure laminated board 605 inside, it has very strong impact resistance and scratch resistance, thereby improving the strength of the whole protection door body 6.

[0036] As shown in Figure 4 and Figure 5 , the laser absorption mechanism 7 includes a special function layer 701, which is covered outside the second high-pressure laminated board 605. The outside of the special function layer 701 is covered with a reflection layer 702, the outside of the reflection layer 702 is covered with an enhanced absorption layer 703, and the outside of the enhanced absorption layer 703 is covered with a basic absorption layer 704. When the laser in the laser room irradiates on the outermost basic absorption layer 704, it is responsible for preliminary absorption of laser energy, and then passes through the enhanced absorption layer 703 to further absorb the remaining laser energy, and then enters the reflection layer 702. Reflect the laser that has not been absorbed to reduce the transmission of the laser, and finally the special function layer 701 is responsible for providing additional protection performance, such as heat resistance.

The outer part of the special function layer 701 is covered with the reflective layer 702 made of aluminum, which can still maintain good reflective performance under high-energy laser irradiation. The main function of the reflective layer 702 is to reflect the laser energy that is not absorbed, thereby reducing the transmission of the laser. The outer part of the reflective layer 702 is covered with the enhanced absorption layer 703, which is used to enhance absorption and further absorb the remaining laser energy. The outermost part of the enhanced absorption layer 703 is covered with the basic absorption layer 704, which is mainly responsible for the initial absorption of laser energy. The material of the basic absorption layer 704 is polycarbonate, which has good processing performance and corrosion resistance, and can be doped with organic dyes or inorganic absorbents to form an absorption filter.

The fixed seat 8 is slidingly connected with the laser room frame 1. When the driving motor 202 drives the screw rod 203 to rotate, the sliding block 9 inside the fixed seat 8 at the lower side of the protective door body 6 is limited to slide in the sliding groove 11 opened at the front lower side of the laser room frame 1, thereby enhancing the stability of the two groups of protective door bodies 6 during movement.

[0039] The working principle of this utility model is as follows: First, connect the external power supply, then turn on the drive motor 202 switch on the front right side of the laser room frame 1. This drives the lead screw 203 inside the fixing frame 201 to rotate. Utilizing the reverse tapping of the external thread of the lead screw 203, the rotation of the lead screw 203 causes the protective door bodies 6 on both sides to move closer together and merge. In the event of an impact during daily use, the aluminum alloy frame 601, along with the internal first high-pressure laminate 602 and second high-pressure laminate 605, provides extremely strong impact and scratch resistance, thereby improving the overall strength of the protective door body 6. Simultaneously, the internal double-layer aluminum plate structure 604 further strengthens the overall structure. Combined with the buffer plate 603 of the first high-pressure laminate 602 and aluminum plate structure 604, it provides a certain buffering effect. Meanwhile, the laser irradiation inside the laser room... The basic absorption layer 704 on the inner side of the door body 6 is responsible for initially absorbing laser energy. Then, it passes through the enhanced absorption layer 703 to further absorb the remaining laser energy. After that, it enters the reflective layer 702 to reflect the unabsorbed laser to reduce laser transmission. Finally, the special function layer 701 is responsible for providing additional protective performance. To prevent the laser from passing through the outside of the protective door body 6, the laser sensor 3 in front of the fixing frame 201 scans for the presence of laser. When laser is scanned outside the protective door body 6, the signal from the laser sensor 3 is transmitted to the signal processor, which is located above the laser sensor 3. The signal processor then transmits the signal to the alarm light 4, causing the alarm light 4 to sound an alarm to remind the surrounding personnel. In this way, the use of the impact-resistant laser room protective door is completed.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
