[0002] With the structure of the full-automatic optical disc burning and printing device becoming more and more compact, how to effectively utilize space has become an important task in the overall machine structure design. For the optical drive inside the device, whether during the installation of the whole machine or during the subsequent use, the optical drive is often disassembled and installed. However, due to the device structure with limited space, when the user disassembles and installs the optical drive, it will be affected by the arrangement of other components inside the device, and the disassembly, installation and maintenance are inconvenient. At present, the conventional optical drive fixing method is to set 4 screw mounting holes on each of the left and right sides of the optical drive. During installation, the optical drive is first fastened to the optical drive rack with screws, and then the optical drive rack is fixed to the chassis. This method has the following defects: (1) The optical drive rack cannot be pre-installed on the device, which will increase the assembly time of the whole machine and reduce the installation efficiency; (2) Once the optical drive needs to be replaced, the optical drive rack still needs to be removed, and the maintenance is still inconvenient; (3) It does not support hot plugging.

[0024] Optionally, the fixing bracket 1 is in a concave shape. The first guide plate 3 and the second guide plate 4 are both vertically arranged. The bottoms of the first guide plate 3 and the second guide plate 4 are respectively fixedly connected to two opposite sides of the support surface 2. G-shaped guide grooves 8 that are bent inwardly into the fixing bracket 1 are provided at the tops of the first guide plate 3 and the second guide plate 4, such that the G-shaped guide groove of the first guide plate 3 faces the first guiding member 6, and the G-shaped guide groove of the second guide plate 4 faces the second guiding member 7.

[0025] Further optionally, the support surface 2, the first guide plate 3, and the second guide plate 4 are all square, adapting to the cubic shape of the optical drive 5. The support surface 2 is the bottom surface of the fixing bracket 1. A plurality of heat dissipation through holes are evenly arranged on the support surface 2. The support surface 2 faces and supports the bottom surface of the optical drive 5.

[0026] Optionally, G-shaped guide grooves that are bent outwardly towards the outside of the optical drive 5 are provided at the tops of the first guiding member 6 and the second guiding member 7. After the optical drive 5 slides into the interior of the fixing bracket 1, the bottom of the G-shaped guide groove of the first guide plate 3 contacts the top of the G-shaped guide groove of the first guiding member 6, and the bottom of the G-shaped guide groove of the second guide plate 4 contacts the top of the G-shaped guide groove of the second guiding member 7, thereby fixing the vertical position of the optical drive 5 inside the fixing bracket 1.

[0027] Further optionally, a first positioning strip 9 that protrudes towards the outside of the optical drive 5 is provided at the bottom of the first guiding member 6. The first positioning strip 9 is horizontally arranged. The length of the first positioning strip 9 is equal to the length of the first guiding member 6. A first positioning tongue 11 that is vertically downward is provided at one end of the first positioning strip 9. At least one mounting hole is provided on the first positioning tongue 11.

[0028] Further optionally, a second positioning strip 10 that protrudes towards the outside of the optical drive 5 is provided at the bottom of the second guiding member 7. The second positioning strip 10 is horizontally arranged. The length of the second positioning strip 10 is equal to the length of the second guiding member 7. A second positioning tongue 12 that is vertically downward is provided at one end of the second positioning strip 10. At least one mounting hole is provided on the second positioning tongue 12.

[0031] The first positioning tongue piece 11 and the second positioning tongue piece 12 correspondingly support the same long side edge of the support surface 2. At both ends of this long side edge, there is respectively a vertically downward secondary tongue piece 13, and there is at least one mounting hole on the secondary tongue piece 13. After the optical drive 5 slides into the fixing frame 1, the first positioning tongue piece 11 and the second positioning tongue piece 12 respectively contact the two secondary tongue pieces, and screws pass through the mounting holes of the first positioning tongue piece 11 and the corresponding secondary tongue piece, and the other screws pass through the mounting holes of the second positioning tongue piece 12 and the corresponding secondary tongue piece, then the optical drive 5 can be fixedly connected to the fixing frame 1.

[0032] Further optionally, there is a square vacant area 14 on the support surface 2. The vacant area 14 is formed by horizontally recessing the long side edge where the secondary tongue piece 13 is located towards the other long side edge. After the optical drive 5 slides into the fixing frame 1, the bottom surface of the optical drive 5 corresponding to the vacant area 14 is exposed, which is convenient for the operator to hold the exposed part of the bottom surface and slide the optical drive 5 out of the fixing frame 1.

[0035] During application, first, the vertical side surfaces of the two guiding plates are mounted inside the burning and printing device through screws, thereby installing the fixing frame 1. The two guiding members are respectively pre-mounted on both sides of the optical drive 5 in advance. The ends of the two guiding members provided with positioning tongue pieces protrude from the surface of the optical drive 5, so that when the subsequent positioning tongue pieces are connected to the corresponding secondary tongue pieces, the optical drive 5 can be located inside the fixing frame 1. Then, the first guiding member 6 faces the first guiding plate 3, the second guiding member 7 faces the second guiding plate 4, and the optical drive 5 is slid into the fixing frame 1. The two guiding members cooperate with the corresponding guiding plates for limiting, playing a positioning role and a fastening role for the optical drive 5.

[0036] Since the fixing frame 1 is directly mounted in the burning and printing device, when it is necessary to disassemble the optical drive 5, only the screws between the positioning tongue piece and the secondary tongue piece need to be removed, and then the position of the optical drive 5 can be slid, so that the optical drive 5 supports hot plugging, and the operation is simple and convenient.

[0037] The fixing frame 1 is integrally formed, the first guiding member 6 and the second guiding member 7 are respectively integrally formed, and the G-shaped guiding grooves at the tops of the respective components are also integrally bent and formed. The two guiding plates and their G-shaped guiding grooves and the support surface 2 form a receiving space for installing the optical drive 5.
