[0002] Composite spacers are components used to support and fix double-layer PCB boards. They are usually made of metal and insulating materials. They play a supporting, fixing and isolating role in electronic equipment to ensure stable connection and correct spacing between PCB boards. These composite spacers are usually composed of internal metal studs and external insulating sleeves. The internal metal studs are used to connect and fix PCB boards, and the external insulating sleeves are used for isolation and insulation. This design enables the composite spacers to provide mechanical support and fixing functions while ensuring electrical isolation and safety.

[0003] However, in the prior art, the composite spacer is integrally formed. When the installed and fixed PCB board needs to be inspected, the bolts need to be unscrewed one by one. After the inspection is completed, the bolts need to be screwed back one by one. The operation is cumbersome and requires a lot of time and manpower, which seriously affects the efficiency of the inspection. Utility Model Content

A composite spacer for supporting and fixing a double-layer PCB board is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a composite spacer column for supporting and fixing a double-layer PCB board, comprising a spacer column body, the upper surface of which is provided with a mounting groove, a support column is embedded in the interior of the mounting groove, a threaded column is fixedly connected to the upper surface of the support column, a positioning hole is provided on the outer surface of the spacer column body and the outer surface of the support column, a slider is slidably embedded in the inner wall surface of the positioning hole, one end of the slider is fixedly connected to a support plate, and a spring is fixedly connected to one side surface of the support plate.

[0006] Furthermore, one end of the spring is fixedly connected to a support member, and one end of the support member is fixedly connected to the outer surface of the spacer column body.

[0007] Furthermore, three positioning blocks are equidistantly and fixedly connected to the inner wall surface of the installation groove, and one side surface of the three positioning blocks is in contact with the outer surface of the support column.

[0008] Furthermore, a telescopic rod is fixedly connected to the outer surface of the support plate, and one end of the telescopic rod is fixedly connected to a side surface of the support member.

[0009] Furthermore, a limiting slide groove is provided on the outer surface of the support column, and a limiting block is embedded on the inner wall surface of the limiting slide groove.

[0010] Furthermore, a side surface of the limit block is fixedly connected to one of the positioning blocks.

[0011] Furthermore, a paddle is fixedly connected to one side surface of the support plate, and an anti-slip pad is fixedly connected to one side surface of the paddle.

[0012] Furthermore, the inner wall surface of the spring is sleeved on the outer surface of the telescopic rod.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when in use, align the threaded column with the installation threaded hole, rotate the spacer column body, and under the action of the thread, the spacer column body is fixedly connected to the installation position through the threaded column, and the slider is embedded in the interior of the positioning hole to fix the spacer column body and the threaded column to prevent the threaded column and the spacer column body from rotating relative to each other, and then fix the equipment to the spacer column body through bolts. When it is necessary to overhaul the installed equipment, push the support plate outward, the support plate squeezes the spring, and the spring compresses the stroke to disengage one end of the slider from the threaded column, lift the spacer column body connected to the equipment upward, remove the equipment, and perform maintenance work. After the maintenance is completed, repeat the above operation to reset the spacer column body and the equipment. The operation is simple and the equipment maintenance efficiency is effectively improved.

[0015] 2. In the utility model, the three positioning blocks are fitted with the outer surface of the support column to provide supporting force for the support column, reduce the contact area with the outside when installing the support column and the spacer column body, reduce the friction during installation, and the telescopic rod limits the movement trajectory of the spring to prevent the spring from bending and deforming when subjected to lateral force, thereby ensuring the normal operation of components. When installing the support column, align the limit block with the limit slide groove, and then push the support column to make the support column embedded in the interior of the installation groove. The limit block cooperates with the limit slide groove to align the positioning hole with the slider, and the support plate is moved by the paddle to facilitate force. The anti-slip pad increases the friction of the fingers to prevent hand slippage, thereby improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS
