DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example

[0029] A quickly assembled instrument test rack comprises a mounting frame, a support frame 9 and a support plate 1; the support frame 9 is connected to the mounting frame, and the support plate 1 is connected to the support frame 9; wherein the mounting frame is used for installing and arranging cables, and the support plate 1 is used for supporting instruments.

[0030] The support frame 9 is a rectangular frame structure made of U-shaped steel and has a clamping part 12 at the bottom. The support frame 9 is connected to the mounting frame through the clamping part 12 and is evenly spaced on the mounting frame. A support rod 8 is fixedly connected to the support frame 9, and a support plate 1 is arranged on the support rod 8. A connecting piece 2 is also arranged on the support plate 1. It should be noted that the rectangular frame made of U-shaped steel needs to ensure that the notch of the U-shaped steel faces inward to facilitate subsequent design. The clamping part 12 includes two clamping plates, which are fixedly connected to both sides of the bottom of the support frame 9. The two clamping plates are clamped on the frame of the mounting frame to fix the position of the support frame 9.

[0031] The connecting member 2 includes a mounting shell 15, a clamping plate 16, a bidirectional screw 17 and a rotating rod 14; the mounting shell 15 is fixedly connected to the mounting plate, and the clamping plate 16 is movably connected to both sides of the mounting shell 15; the bidirectional screw 17 is rotatably connected in the mounting shell 15, and the clamping plates 16 on both sides are respectively threadedly connected to both sides of the bidirectional screw 17; the rotating rod 14 is rotatably connected to the mounting shell 15 and the bottom of the rotating rod 14 extends into the mounting shell 15, the bottom of the rotating rod 14 is fixedly connected to the first bevel gear 19, the middle of the bidirectional screw 17 is fixedly connected to the second bevel gear 18, and the first bevel gear 19 is meshed with the second bevel gear 18. Among them, the threads on both sides of the double-headed screw are in opposite directions, and the connecting member 2 is used to extend and insert into the inner groove of the support frame 9 by controlling the clamping plate 16.

[0032] Specifically, when in use, the mounting frame, the support frame 9 and the support plate 1 are separable and can be transported and carried separately. When assembling, the mounting frame is fixed at a specified position, and the clamping portion 12 at the bottom of the support frame 9 is clamped on the upper frame of the mounting frame to determine the position of the support frame 9. Then, the support plate 1 is placed on the support rod 8, and the support plate 1 is moved so that the connecting member 2 on the support plate 1 is aligned with the support frame 9. The support rod 8 is used to place the support plate 1, and the connecting member 2 is used to position the support plate 1 to prevent the support plate 1 from moving laterally. The rotating rod 14 is twisted, and the first bevel gear 19 is driven to rotate by the rotating rod 14, and the first bevel gear 19 drives the second bevel gear 18 to rotate, and the second bevel gear 18 drives the double-headed screw to rotate. The clamping plate 16 is restricted by the mounting shell 15 and cannot rotate, so the clamping plate 16 will move in the axial direction of the double-headed screw. Since the threads on both sides of the double-headed screw have opposite rotation directions, when the double-headed screw rotates, the clamping plates 16 on both sides will approach or move away from each other. When the clamping plates 16 on both sides move away from each other, the clamping plates 16 will extend outward and insert into the inner groove of the support frame 9. It should be noted here that the inner groove refers to the groove naturally formed by the U-shaped steel. The clamping plates 16 enter the inner groove and press against the support frame 9. Through the above steps, the support plate 1 can be stably connected to the support frame 9. Then the instrument can be placed on the support plate 1 for testing.

[0033] In a preferred embodiment, the installation frame includes a power cable installation frame 10 and a signal cable installation frame 11, and the power cable installation frame 10 and the signal cable installation frame 11 are of the same size. There are many power cables and signal cables at the test site. By setting up two installation frames, the signal cables and power cables can be partitioned to avoid cross-line interference.

[0034] In a preferred embodiment, a limit plate is fixed to the bottom of the mounting plate, and the limit plate abuts against the support rod 8. After the limit plate is set at the bottom of the mounting plate, when the mounting plate is placed on the support rod 8 and pushed, the limit plate on the mounting plate will limit the movement of the mounting plate, preventing the mounting plate from falling off the support rod 8 when adjusting the position of the mounting plate. At the same time, by adjusting the position of the limit plate, it is also convenient to align the mounting plate with the support frame 9.

[0035] In a preferred embodiment, a plurality of bolt holes are provided at the bottom of the support frame 9, and a plurality of matching bolt holes are provided at the top of the mounting frame. When the test rack needs to be used for a long time, it is necessary to further improve the overall stability of the test rack. Therefore, after the bolt holes are provided, the mounting frame and the support frame 9 can be connected by bolts. After the support frame 9 and the mounting frame are bolted together, they have the advantages of being sturdy and durable. At the same time, the bolt connection method also has the advantage of convenient disassembly. When the test rack needs to be disassembled and transported later, the support frame 9 can be easily separated from the mounting frame.

[0036] In a preferred embodiment, a plurality of connectors 7 are connected to one side of the support frame 9, and the connectors 7 are U-shaped structures with the opening facing upward; the support frame 9 is hung with a plurality of connecting rods 4 through the connectors 7; and the connecting rods 4 are also connected with a back plate 5. The connectors 7 of this structure can be conveniently installed to facilitate installation of the connecting rods 4. When in use, the connecting rods 4 can be directly hung on the connectors 7, and finally a back plate 5 is connected to the connecting rods 4. Further optimized, a hanging joint 6 is fixed to the back plate 5, and the back plate 5 is hung on the connecting rod 4 through the hanging joint 6. The hanging joint 6 on the back plate 5 is an L-shaped structure, and the back plate 5 can be directly hung on the connecting rod 4 through the hanging joint 6, so as to facilitate the arrangement of the back plate 5. Further optimized, a connecting portion 3 is provided in the middle of the back plate 5. The back plate 5 is used to set auxiliary components such as plugs, and the protruding connecting portion 3 provided in the middle of the back plate 5 can facilitate the setting of plugs or other auxiliary components on the back plate 5.

[0037] In a preferred embodiment, the cross section of the clamping plate 16 away from the bidirectional screw rod 17 is a trapezoidal structure. In other words, the two sides of the end of the clamping plate 16 are inclined structures. This structure can play a guiding role, so that the clamping plate 16 can be easily inserted into the inner groove of the support frame 9.

[0038] In a preferred embodiment, a rotating head 13 is fixedly connected to the top of the rotating rod 14. More specifically, the rotating head 13 is also provided with anti-slip grooves, and the rotating rod 14 can be conveniently twisted through the design of the rotating head 13.

[0039] In a preferred embodiment, a rotating part 20 is fixedly connected in the mounting shell 15, and the bidirectional screw rod 17 is rotatably connected to the rotating part 20. The rotating part 20 is used to ensure the stability of the bidirectional screw rod 17 and prevent the bidirectional screw rod 17 from moving in the mounting shell 15.
