[0050] See also Figures 1 to 5As shown, an embodiment of the present application provides a tray for fixing a PCS, comprising: a base 1, a rear fixing member 2, a front fixing member 3, and an upper cover 4. A first card slot 11 is provided on the base 1, and the rear fixing member 2 has a first claw 24. The rear fixing member 2 and the base 1 are detachably connected, and the claw of the rear fixing member 2 can be engaged with the first card slot 11. The rear fixing member 2 is used to press and fix the rear end of the PCS device 6. The front fixing member 3 is fixed to the base 1, and the front fixing member 3 is used to connect and fix with the front part of the PCS device 6. The upper cover 4 is detachably connected to the base 1, and the upper cover 4 covers the front fixing member 3 and at least part of the rear fixing member 2.

[0051] The front fixing member 3 and the rear fixing member 2 are respectively located at the front and rear ends of the PCS device 6 to fix the PCS device 6 between the front fixing member 3 and the rear fixing member 2. The front fixing member 3 and the rear fixing member 2 fix the PCS device 6 at both ends of the PCS device 6, respectively, which enhances the strength and stability of the fixing structure, and the PCS device 6 will not be loose at one end and tight at the other end. The rear fixing member 2 of the tray for fixing the PCS of the present application has a first claw 24, and a first slot 11 is provided on the base 1. When the rear fixing member 2 and the base 1 are connected, the first claw 24 is engaged with the first slot 11. The fixing method of the rear fixing member 2 and the base 1 includes a snap-fit ​​structure, which makes the assembly structure more solid and improves the ability to resist external impact.

[0052] In some possible embodiments, the rear fixing member 2 includes a housing, and the first claw 24 is connected to the housing. When the rear fixing member 2 is connected to the base 1, a fixing cavity is formed between the housing and the base 1, and the rear end of the PCS device 6 can be accommodated in the fixing cavity. The housing can cooperate with the base 1 to press and fix one end of the housing of the PCS device 6.

[0053] In some possible implementations, see Figure 4 and Figure 5 As shown, the rear fixing member 2 includes an end plate 21, two side plates 22 and a top plate 23. The two side plates 22 are respectively connected to the two sides of the end plate 21. The top plate 23 is located on the top of the end plate 21 and is respectively connected to the two side plates 22. The first claw 24 is provided on the side plate 22. When the rear fixing member 2 and the base 1 are connected, the top plate 23, the side plates 22 and the base 1 enclose the fixing cavity, and the first claw is clamped in the first slot 11 on the base.

[0054] Among them, the first clamping claw 24 has a clamping strip 241 and a connecting strip 242, and the connecting strip 242 respectively connects the clamping strip 241 and the thickness end surface of the lower edge of the side panel 22. When the rear fixing member 2 and the base 1 are connected, the thickness end surface of the lower edge of the side panel 22 is attached to the base 1, and the clamping strip 241 is clamped to the side of the base 1 facing away from the upper cover 4.

[0055] When assembling the rear fixing member 2 and the base 1, the position of the rear fixing member 2 can be adjusted first so that the first claws 24 on both sides of the rear fixing member 2 respectively penetrate the corresponding first slots 11 on the base 1, and then the rear fixing member 2 can be translated along the extension direction of the clip 241 to make the clip 241 slide away from the first slot until the connecting strip 242 hits the end of the first slot. At this time, the rear fixing member 2 is assembled in place, and the rear fixing member 2 and the base 1 can be further connected and fixed by fasteners.

[0056] For example, combined with Figure 4 and Figure 5 As can be seen, a flange 25 is provided on the lower edge of the end plate 21, and the flange 25 is bent toward the side away from the side plate 22. When the rear fixing member 2 and the base 1 are connected, the flange 25 is attached to the base 1 and fixed to the base 1 by fasteners. The fasteners can be screws.

[0057] In some possible scenarios, see Figure 2 As shown, the front fixing member 3 includes a fixing plate 31 and a connecting plate 32. The connecting plate 32 is provided with a connection hole for connecting to the PCS device 6, which can be conveniently connected to the housing of the PCS device 6 via fasteners. The fasteners can be screws, the screw shafts of which pass through the connection holes in the connecting plate 32 to connect to the housing of the PCS device 6, with the screw caps being confined to the connecting plate 32. The fixing plate 31 is perpendicularly connected to the connecting plate 32 and is closely connected to the base 1. The fixing plate 31 can be connected to the base 1 via fasteners, which can be screws, the screw shafts of which pass through the fixing plate 31 to connect to the base 1, with the screw caps being confined to the fixing plate 31.

[0058] The connecting plate 32 may include a first connecting plate 321, a second connecting plate 322 and a third connecting plate 323. The second connecting plate 322 is located between the first connecting plate 321 and the third connecting plate 323, and is respectively connected to the first connecting plate 321 and the third connecting plate 323. The first connecting plate 321 and the second connecting plate 322 are respectively used to fit the PCS device 6, and the first connecting plate 321 has the connecting hole. The fixing plate 31 is located at the lower edge of the second connecting plate 322 and the third connecting plate 323, and is respectively connected to the second connecting plate 322 and the third connecting plate 323.

[0059] The front end of the PCS device 6 has a vertical corner, and the second connecting plate 322 and the first connecting plate 321 can be attached to the two vertical surfaces of the vertical corner respectively. The second connecting plate 322 can not be provided with a connecting hole, and is limited to the front end of the PCS device 6. The second connecting plate 322 cooperates with the rear fixing part 2 to limit the movement of the PCS device 6 in the front-rear direction. The front fixing part 3 is usually arranged in pairs and is arranged on both sides of the base 1 along the width direction. The two front fixing parts 3 are respectively located at the vertical corners on both sides of the front end of the PCS device 6, and the two front fixing parts 3 cooperate to limit the movement of the PCS device 6 in the left-right direction (such as the width direction). By arranging the connecting plate 32 as the first connecting plate 321, the second connecting plate 322 and the third connecting plate 323 connected in sequence, the structural strength of the front fixing part 3 can be obviously enhanced.

[0060] It should be noted that one PCS device 6 can be arranged on the base 1, and two PCS devices 6 can also be arranged on the base 1. The front fixing part 3 and the rear fixing part 2 are respectively arranged at the two ends of the PCS device 6 on the base 1.

[0061] In some possible embodiments, the second clamping jaw 41 is arranged on the upper cover 4, and the second clamping groove 12 is arranged on the base 1. In the connected state of the upper cover 4 and the base 1, the second clamping jaw 41 is clamped on the second clamping groove 12.

[0062] The upper cover 4 of the tray for fixing the PCS has the second clamping jaw 41, and the second clamping groove 12 is arranged on the base 1. When the upper cover 4 and the base 1 are connected, the second clamping jaw 41 is clamped on the second clamping groove 12. The fixing mode of the upper cover 4 and the base 1 includes a buckle structure, so that the assembly structure is more firm, and the ability to resist external force impact is improved. The local position of the upper cover 4 and the base 1 are connected and assembled through the buckle structure, which saves space and effectively fixes in a limited space. The structure of the second clamping jaw 41 is the same as that of the first clamping jaw 24, so the assembly mode and effect are also the same.

[0063] In some possible embodiments, the tray for fixing the PCS further includes a front panel 5 connected to the base 1. One end of the upper cover 4 is connected to the front panel 5 through a fastener, and the other end of the upper cover 4 is provided with the second clamping jaw 41.

[0064] For example, the front panel 5 is provided with a turned edge 25, and the edge of one end of the upper cover 4 is attached to the turned edge 25. The upper cover 4 and the turned edge 25 are connected and fixed through a fastener.

[0065] When two PCS devices 6 are arranged on the base 1, the front panel 5 can integrate the electrical connection components (such as interfaces and sockets and the like) of the two PCS devices 6, which is convenient for container wiring.

[0066] In some possible implementations, the base 1 is provided with a lifting seat 13 on its edge, which can be easily connected to a lifting device and transported by the lifting device, thus avoiding manual handling and significantly reducing the workload of workers. The upper cover 4 can be provided with an escape notch 42 at the position corresponding to the lifting seat 13.

[0067] In some possible implementation schemes, a plug-in piece 43 may be provided on the edge of the upper cover 4 , and a slot 14 may be provided on the base 1 . When the upper cover 4 is connected to the base 1 , the plug-in piece 43 is plugged into the slot 14 .
