Description

Technical Field

[0001] This utility model relates to the field of laser engraving machine technology, and in particular to a protective cover structure for a billboard laser engraving machine. Background Technology

[0002] A laser engraving machine for billboards is a device that uses a high-energy laser beam to precisely engrave, cut, or mark the surface of billboard materials. Its core principle is to use the high temperature generated by a focused laser beam to melt, vaporize, or ablate the material surface, thereby forming the desired text, patterns, or designs. Currently, laser engraving machines lack a protective shield structure, making it impossible to create a closed engraving space during the process.

[0003] In existing technology, a protective cover body is set on the engraving machine, which is composed of an upper cover plate, a lower base plate, a front cover plate and a rear cover plate to form a closed engraving space.

[0004] However, when it is necessary to open the protective cover, the current protective cover does not have a folding function, and the area occupied by the protective cover after opening is too large, making it inconvenient to use. Utility Model Content

[0005] The purpose of this utility model is to provide a protective cover structure for a laser engraving machine for billboards, which solves the problem that the existing protective covers do not have a folding function and occupy too much space when opened, making them inconvenient to use.

[0006] To achieve the above objectives, this utility model provides a protective cover structure for a laser engraving machine for billboards, including an engraving machine body, a first protective plate, a second protective plate, a support mechanism, and a folding mechanism;

[0007] The folding mechanism includes a limiting unit, a triangular bracket, two rotating shafts and two hinges. The upper end of the engraving machine body has an opening, and the two sides of the opening have grooves respectively.

[0008] The limiting unit includes a housing, a spring, a limiting rod, a limiting ring, and a circular ring;

[0009] One end of each of the two rotating shafts is rotatably adapted to the corresponding groove, and the other end of each of the two rotating shafts is fixedly connected to the side of the second protective plate. The first protective plate and the second protective plate are respectively disposed at the opening, and the first protective plate is located to the left of the second protective plate. The two ends of the two hinges are fixedly connected to the upper ends of the first protective plate and the second protective plate, respectively. The triangular bracket is fixedly connected to the right end of the engraving machine body. The outer shell is fixedly connected to the upper end of the second protective plate. The limiting ring is fixedly connected to the upper end of the first protective plate. One end of the limiting rod passes through the outer shell. The ring is fixedly sleeved on the outside of the limiting rod and located inside the outer shell. The two ends of the spring are fixedly connected to the inner wall of the outer shell and the ring, respectively.

[0010] The folding mechanism further includes two sealing gaskets, which are fixedly connected to the sides of the first protective plate and the second protective plate, respectively, and the two sealing gaskets are in contact with each other.

[0011] The folding mechanism further includes a first handle, a second handle, a third handle, and a soft pad. The soft pad is fixedly connected to the upper end of the triangular bracket. The first handle is fixedly connected to the left end of the first protective plate. The second handle is fixedly connected to the lower end of the first protective plate. The third handle is fixedly connected to the lower end of the second protective plate.

[0012] The support mechanism includes two first round rods and two second round rods.

[0013] The two first round rods and the two second round rods are respectively located below the opening.

[0014] This utility model discloses a protective cover structure for a laser engraving machine for billboards. By pulling the first protective plate upward, the first protective plate rotates to the right under the action of the two hinges, while simultaneously pulling the limiting rod outward. After the first protective plate has fully rotated, the limiting rod is released, and under the action of the spring, it returns to its original position, adapting to the limiting ring, thereby limiting and fixing the first protective plate. Then, the second protective plate is flipped to the right again, finally bringing the inner wall of the first protective plate into contact with the upper end of the triangular bracket. This completes the folding and unfolding of the protective structure of the device. Thus, the device can fold the protective structure and reduce the floor space occupied after unfolding, making it convenient to use. Attached Figure Description

Figure 6 This is a partial structural schematic diagram of the engraving machine body 101 of this utility model.

[0025] This utility model provides a protective cover structure for a laser engraving machine for billboards, including an engraving machine body 101, a first protective plate 102, a second protective plate 103, a support mechanism, and a folding mechanism; the folding mechanism includes a limiting unit, a triangular bracket 104, two rotating shafts 105, two hinges 106, two sealing gaskets 107, a first pull handle 108, a second pull handle 109, a third pull handle 110, and a soft pad 111; the upper end of the engraving machine body 101 has an opening 112, and the two sides of the opening 112 have grooves 113 respectively; the limiting unit includes a shell 114, a spring 115, a limiting rod 116, a limiting ring 117, and a circular ring 118; the support mechanism includes two first circular rods 119 and two second circular rods 120.

[0026] In this specific embodiment, by pulling the first protective plate 102 upward, the first protective plate 102 rotates to the right under the action of the two hinges 106, while simultaneously pulling the limiting rod 116 outward. After the first protective plate 102 has fully rotated, the limiting rod 116 is released, and under the action of the spring 115, it returns to its original position, adapting to the limiting ring 117, thereby limiting and fixing the first protective plate 102. Then, the second protective plate 103 is flipped to the right again, finally bringing the inner wall of the first protective plate 102 into contact with the upper end of the triangular bracket 104, thus completing the folding and opening of the protective structure of this device. Therefore, this device can fold the protective structure and reduce the floor space occupied after opening, making it convenient to use.

[0027] One end of each of the two rotating shafts 105 is rotatably adapted to the corresponding groove 113, and the other end of each of the two rotating shafts 105 is fixedly connected to the side of the second protective plate 103. The first protective plate 102 and the second protective plate 103 are respectively disposed at the opening 112, with the first protective plate 102 located to the left of the second protective plate 103. The two ends of the two hinges 106 are fixedly connected to the upper ends of the first protective plate 102 and the second protective plate 103, respectively. The triangular bracket 104 is fixedly connected to the right end of the engraving machine body 101. The outer shell 114 is fixedly connected to the upper end of the second protective plate 103. The limiting ring 117 is fixedly connected to the upper end of the first protective plate 102. One end of the limiting rod 116 passes through the outer shell 114. The ring 118 is fixedly sleeved on the outside of the limiting rod 116 and located inside the outer shell 114. The two ends of the spring 115 are fixedly connected to the inner wall of the outer shell 114 and the ring 118, respectively. By pulling the first protective plate 102 upward, the first protective plate 102 rotates to the right under the action of the two hinges 106, while simultaneously pulling the limiting rod 116 outward. After the first protective plate 102 has fully rotated, the limiting rod 116 is released, and under the action of the spring 115, it returns to its original position, adapting to the limiting ring 117, thereby limiting and fixing the first protective plate 102. Then, the second protective plate 103 is flipped to the right again, finally bringing the inner wall of the first protective plate 102 into contact with the upper end of the triangular bracket 104, thus completing the folding and opening of the protective structure of this device. As a result, this device can fold the protective structure and reduce the floor space occupied after opening, making it convenient to use.

[0028] Secondly, the two sealing gaskets 107 are fixedly connected to the sides of the first protective plate 102 and the second protective plate 103 respectively, and the two sealing gaskets 107 are in contact with each other. When the first protective plate 102 and the second protective plate 103 are closed, the two sealing gaskets 107 can seal the gap between the first protective plate 102 and the second protective plate 103, preventing light leakage and material splashing during engraving.

[0029] Meanwhile, the soft pad 111 is fixedly connected to the upper end of the triangular bracket 104, the first pull handle 108 is fixedly connected to the left end of the first protective plate 102, the second pull handle 109 is fixedly connected to the lower end of the first protective plate 102, and the third pull handle 110 is fixedly connected to the lower end of the second protective plate 103. When folding, pulling the first pull handle 108 facilitates flipping the first protective plate 102 onto the second protective plate 103, and then using the second pull handle 109 facilitates flipping both the first protective plate 102 and the second protective plate 103 onto the triangular bracket 104. When reclosing is required, pulling the third pull handle 110 facilitates flipping the second protective plate 103 back to its original position. The soft pad 111 protects the flipped-over first protective plate 102 and the second protective plate 103, preventing them from making hard contact with the triangular bracket 104, which could lead to wear and noise.

[0030] Finally, two first round rods 119 are symmetrically arranged on the inner top wall of the engraving machine body 101, and respectively contact the lower end of the first protective plate 102. Two second round rods 120 are symmetrically arranged on the inner top wall of the engraving machine body 101, and respectively contact the lower end of the second protective plate 103. The two first round rods 119 and the two second round rods 120 are located below the opening 112. When the first protective plate 102 and the second protective plate 103 are closed, the two first round rods 119 and the two second round rods 120 respectively provide load-bearing support.

[0031] When using the protective cover structure for the laser engraving machine of this utility model, by pulling the first protective plate 102 upward, the first protective plate 102 rotates to the right under the action of the two hinges 106, while simultaneously pulling the limiting rod 116 outward. After the first protective plate 102 has fully rotated, the limiting rod 116 is released, and under the action of the spring 115, it returns to its original position, adapting to the limiting ring 117, thereby limiting and fixing the first protective plate 102. Then, the second protective plate 103 is flipped to the right again, finally making the inner wall of the first protective plate 102 contact the upper end of the triangular bracket 104, thus completing the folding and opening of the protective structure of this device. Therefore, this device can fold the protective structure and reduce the floor space occupied after opening, making it convenient to use. When the first protective plate 102 and the second protective plate 103 are closed, the two sealing gaskets 107 can seal the first protective plate 102 and the... The gaps between the second protective plates 103 are sealed to prevent light leakage and material splashing during engraving. When folding, pulling the first handle 108 facilitates flipping the first protective plate 102 onto the second protective plate 103, and then using the second handle 109 facilitates flipping the first protective plate 102 and the second protective plate 103 together onto the triangular bracket 104. When it is necessary to close again, pulling the third handle 110 facilitates flipping the second protective plate 103 back to its original position. The soft pad 111 protects the flipped first protective plate 102 and the second protective plate 103, preventing them from making hard contact with the triangular bracket 104, which could cause wear and noise. When the first protective plate 102 and the second protective plate 103 are closed, the two first round rods 119 and the two second round rods 120 provide load-bearing support.

[0032] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
