[0030] Furthermore, in some embodiments, a covering plate 21 is provided at one end of the second sliding structure 2 facing outside the frame body 1, and part of the frame body 1 is provided with a through hole connecting the receiving space 11 and the outside of the frame body 1, and the axial projection surface of the covering plate 21 covers the through hole, and the second sliding structure 2 is slidably connected to the first sliding structure 12 through the through hole, and the holding portion 3 of the second sliding structure 2 facing the frame protrudes from the side of the covering plate 21 away from the receiving space 11.

[0031] Specifically, the frame 1 is provided with a through hole at a position close to the first sliding structure 12, so that when the second sliding structure 2 is slidably connected to the first sliding structure 12, the second sliding structure 2 can enter the receiving space 11 or be pulled out of the frame 1 through the through hole, and the operation is convenient and quick. The second sliding structure 2 is also provided with a cover plate 21, so when the second sliding structure 2 enters the receiving space 11 and is connected to the first sliding structure 12, the cover plate 21 can cover the through hole, so that the relative sealing of the entire device can be achieved, and dust can be prevented from entering the frame 1 and contaminating the internal components of the frame 1, which can extend the service life of the device.

[0032] Furthermore, in some embodiments, a plurality of first slideways 111 are defined in the receiving space 11, and the first slideways 111 correspond to the first sliding structures 12 one by one. The first sliding structure 12 includes two guide structures respectively arranged on both sides of the first slideway 111 and extending along the length direction of the frame 1. The second sliding structure 2 includes an assembly structure 22 for assembling the frequency conversion module and extending along the length direction of the frame 1. Both sides of the assembly structure 22 are respectively assembled on the two guide structures, and the assembly structure 22 can move along the guide structure.

[0033] Specifically, a plurality of first slides 111 can be defined in the receiving space 11, and guide structures are provided on both sides of each first slide 111, and two guide structures in a first slide 111 form a first sliding structure 12. The second sliding structure 2 may include an assembly structure 22. Exemplarily, the assembly structure 22 may be a tray, one side of which is used to assemble the frequency conversion module, and the two sides of the tray are used to be slidably connected with the two guide structures. When the frequency conversion module needs to be replaced or added, the gripping portion 3 can be pulled so that the two sides of the tray are pulled out of the receiving space 11 to the outside of the frame 1 through the guidance of the guide structure, and the frequency conversion module can be replaced or added at this time. Then, the gripping portion 3 is pulled again, and the tray is guided by the guide structure to enter the receiving space 11, and the whole process is convenient and quick to operate.

[0034] In some embodiments, four first slide rails 111 are defined in the receiving space 11 , and the 1U chassis is provided with four first sliding structures 12 and four second sliding structures 2 , so that the system can achieve a 4-way channel capacity on the 1U chassis.

[0035] Furthermore, in some specific embodiments, the guide structure includes two guide plates 121 that are orthogonal to the side walls of the first slide 111 and are spaced apart along the height direction of the frame 1 , the side of the assembly structure 22 is clamped between the two guide plates 121 , and the assembly structure 22 can move along the guide plates 121 .

[0036] Specifically, a guide structure may include two guide plates 121, and the two guide plates 121 are spaced apart along the height direction of the frame 1. Moreover, in the same first slide 111, the two guide structures are symmetrically arranged. In the same first slide 111, one side edge of the assembly structure 22 is clamped between the two guide plates 121 of one of the guide structures, and the other side edge of the assembly structure 22 is clamped between the two guide plates 121 of the other guide structures. With such arrangement, the two sides of the assembly structure 22 are respectively guided by the guide plates 121 on both sides, so that the sliding connection between the first sliding structure 12 and the second sliding structure 2 can be realized, and the assembly structure 22 can be moved along the extended length of the guide plate 121 by pulling the gripping portion 3, so that the hot plugging of the frequency conversion module can be realized, and the operation is convenient and quick.

[0037] Further, in some embodiments, multiple first slideways 111 are distributed up and down along the height direction of the frame 1, so the lower guide plate 121 of the upper first slideway 111 can be the upper guide plate 121 of the lower first slideway 111. Such an arrangement can save materials and reduce costs.

[0038] Further, the guide plate 121 includes a sub-guide plate extending along the length direction of the frame 1 ; or, the guide plate 121 includes a plurality of sub-guide plates spaced apart and distributed along the length direction of the frame 1 .

[0039] In some possible implementations, a guide plate 121 is a sub-guide plate, and the extension length of the sub-guide plate along the length of the frame 1 is equal to the extension length of the guide structure, so that the side of the assembly structure 22 can be clamped between the two sub-guide plates of the guide structure, ultimately realizing hot plugging of the frequency conversion module, which is convenient and quick to operate.

[0040] In some implementations, one guide plate 121 may include multiple sub-guide plates, and the extension length of the sub-guide plates along the length direction of the frame 1 is less than the extension length of the guide structure. Along the length direction of the frame 1, multiple sub-guide plates are combined to form one guide plate 121. This arrangement can save materials, and can provide a buffer space for the assembly structure 22 and the guide structure during the relative sliding process, so that the assembly structure 22 and the guide structure can slide relative to each other better.

[0041] Furthermore, in some implementable embodiments, the sub-guide plates of the two guide plates 121 in the same guide structure may be arranged in a staggered manner, so as to better achieve a stable connection between the assembly structure 22 and the guide structure.

[0042] Furthermore, in some specific embodiments, the guide structure includes a first guide groove opened on the side wall of the first slide 111 and the opening direction is parallel to the width direction of the frame 1, and the side of the assembly structure 22 is embedded in the first guide groove, and the assembly structure 22 can move along the first guide groove.

[0043] Specifically, the transverse cross-sectional shape of the first guide groove can be U-shaped, [-shaped, C-shaped, V-shaped, etc. The two sides of the assembly structure 22 are respectively embedded in the two first guide grooves, so that the assembly structure 22 can move along the extension direction of the first guide groove through the guiding effect of the first guide groove, and finally realize the hot plug of the frequency conversion module, which is convenient and quick to operate.

[0044] Furthermore, in some specific embodiments, the guide structure includes a convex plate protruding from the side wall of the first slide 111 and extending along the length direction of the frame 1, and a second guide groove opened at the top or bottom of the convex plate and extending along the length direction of the frame 1, and a guide protrusion cooperating with the second guide groove is provided at the bottom or top of the side of the assembly structure 22, and the guide protrusion is connected to the second guide groove, and the assembly structure 22 can move along the second guide groove.

[0045] Specifically, along the height direction, the side of an assembly structure 22 where the frequency conversion module is assembled is the top side, and the side away from the frequency conversion module is the bottom side. Exemplarily, a second guide groove extending along the length direction of the frame 1 may be provided on the top side of the convex plate, and the transverse cross-sectional shape of the second guide groove may be U-shaped, V-shaped, [-shaped, C-shaped, etc.; a guide protrusion may protrude from the bottom side of the side of the assembly structure 22, which may be a guide protrusion extending along the length direction of the frame 1, or a plurality of guide protrusions distributed at intervals along the length direction of the frame 1. Through the cooperation of the guide protrusion and the second guide groove, the assembly structure 22 may be realized along the extension direction of the second guide groove, thereby finally realizing hot plugging of the frequency conversion module, and the operation is convenient and quick.

[0046] Further, in some embodiments, the frame 1 is provided with a first clip structure, the holding portion 3 is provided with a second clip structure 31, and the holding portion 3 can be rotatably connected to the second sliding structure 2; when the second sliding structure 2 and the frame 1 are in a first connection state, and the holding portion 3 and the second sliding structure 2 are in a second connection state, the first clip structure is clipped to the second clip structure 31; when the holding portion 3 and the second sliding structure 2 are in a third connection state, the first clip structure and the second clip structure 31 can be separated.

[0047] Specifically, the second sliding structure 2 and the frame 1 are in the first connection state, indicating that the second sliding structure 2 enters the receiving space 11, and the first sliding structure 12 and the second sliding structure 2 slide into place; and the grip portion 3 and the second sliding structure 2 are in the second connection state, indicating that the grip portion 3 is rotated to the first preset angle, and at this time, the first clamping structure can be just clamped to the second clamping structure 31. Therefore, the assembly connection between the second sliding structure 2 and the frame 1 can be achieved, and the assembly connection between the first sliding structure 12 and the second sliding structure 2 can be achieved, and the device can be used for work. When it is necessary to replace the frequency conversion module or add a frequency conversion module, it is only necessary to rotate the grip portion 3 to the second preset angle so that the grip portion 3 and the second sliding structure 2 are in the third connection state, and then the first clamping structure and the second clamping structure 31 can be separated. At this time, the second sliding structure 2 is pulled out of the frame 1, and the frequency conversion module can be replaced or added, and the operation is convenient and quick.

[0048] Further, in some specific embodiments, the first clamping structure can be a clamping column, and the second clamping structure 31 can be a C-shaped clamping ring arranged at the end of the holding portion 3. When the holding portion 3 is at the first preset angle and the first clamping structure and the second clamping structure 31 are connected, the clamping column is sleeved in the clamping ring, and the opening of the clamping ring is facing the width direction of the frame 1, and the clamping column cannot be separated from the clamping ring, thereby realizing the assembly connection between the second sliding structure 2 and the frame 1, and the device can be used for work. When the holding portion 3 is rotated to the second preset angle, so that the opening of the clamping ring is facing the length direction of the frame 1, the holding portion 3 is pulled at this time, so that the clamping ring can be separated from the clamping column, thereby realizing the separation of the first clamping structure and the second clamping structure 31. It can be understood that the first preset angle and the second preset angle are the rotation angles of the holding portion 3, which can be set according to actual conditions.

[0049] Furthermore, in some specific embodiments, the device chassis also includes a reset member, which is connected between the grip portion 3 and the frame body 1; the reset member is used to provide a reset force to enable the first clamping structure and the second clamping structure 31 to be clamped.

[0050] Specifically, the reset member can be an elastic sheet, a spring, a silicone member, a magnetic member, etc. Exemplarily, the reset member is a spring, one end of which is connected to the gripping portion 3 and the other end is connected to the frame 1. The second sliding structure 2 may include a plane parallel to the length direction and / or width direction of the frame 1, such as a tray; the planes of the gripping portion 3 and the second sliding structure 2 are rotatably connected by a rotating shaft. When the gripping portion 3 is rotated to a first preset angle, the first clamping structure and the second clamping structure 31 are separated, and the gripping portion 3 is pulled to pull the second sliding structure 2 out of the frame 1, and the frequency conversion module can be assembled or replaced. After the assembly or replacement is completed, the gripping portion 3 can be rotated and pushed at the same time to push the second sliding structure 2 into the receiving space 11. When the first sliding structure 12 and the second sliding structure 2 are connected in place, the gripping portion 3 can be released. At this time, the spring can provide a reset force, so that the gripping portion 3 is automatically reset, so that the first clamping structure and the second clamping structure 31 can be automatically clamped, and the second sliding structure 2 and the frame 1 are automatically connected.

[0051] Furthermore, in some embodiments, a second slide is defined in the receiving space 11, and the power module 4 of the main module of the device can be slidably connected to the second slide, so that the power module 4 can be hot-swapped and replaced without dismantling the entire device. In addition, in some embodiments, the frame 1 can include a first shell and a second shell, the first slide 111 can be set at the first shell, and the second slide can be set at the second shell, so that the spatial structure can be used in all directions to form a multi-channel highly integrated platform, making the overall maintenance of the device convenient.

[0052] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0053] The above is a description of the technical solution provided by the utility model. For technicians in this field, according to the ideas of the embodiments of the utility model, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the utility model.
