Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to a novel hybrid voltage high-frequency circuit board. Background Technology

[0002] A search revealed that application number 202320009744.4 discloses a mixed-voltage high-frequency circuit board, including a mounting frame. The mounting frame has a rectangular structure, and four U-shaped support feet are symmetrically welded on the left and right side plates of the mounting frame. The bottom plates of the U-shaped support feet are locked together with the housing of the electrical appliance. Four positioning short posts are symmetrically arranged through the four corners of the mounting frame, and two circuit boards are symmetrically fitted on the four positioning short posts. Two buffer springs are symmetrically fitted on each of the four positioning short posts.

[0003] In the application for a mixed-voltage high-frequency circuit board, eight blocking and positioning components can hold the high-voltage and low-voltage circuit boards in place on four positioning posts. A simple push of the T-shaped force rods outwards can cause the baffle to slide outwards and displace the circuit boards from the positioning posts. However, in this way, each circuit board is held in place by four blocking and positioning components. The installation and removal of the circuit boards require pulling the four T-shaped force rods outwards, which means that at least three workers are needed to install and remove the circuit boards. This causes inconvenience to the use of the equipment and leaves room for improvement. Therefore, we propose a new type of mixed-voltage high-frequency circuit board. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide a novel mixed-voltage high-frequency circuit board.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a novel mixed-voltage high-frequency circuit board, comprising a mounting frame and a high-voltage high-frequency circuit board and a low-voltage circuit board respectively disposed on the upper and lower sides of the mounting frame. Four U-shaped support feet are symmetrically welded on the left and right sides of the mounting frame. Four positioning short posts are disposed at the four corners of the mounting frame, penetrating the four corners of both the high-voltage high-frequency circuit board and the low-voltage circuit board. Four sets of mounting brackets are fixedly installed at the front and rear ends of the upper and lower side walls of the mounting frame. Positioning mechanisms are provided on the four sets of mounting brackets. The positioning mechanisms include four limiting slide rods fixedly connected to the four sets of mounting brackets and four bidirectional threaded rods rotatably connected to the four sets of mounting brackets. Eight blocking positioning components are slidably connected to the outer wall of the four limiting slide rods. Eight blocking positioning discs that abut against the upper and lower ends of the four positioning short posts are fixedly connected to one end of each of the eight blocking positioning components. Eight adjusting slide plates that are slidably connected to the outer wall of the four limiting slide rods are threaded to the left and right ends of the four bidirectional threaded rods. Eight blocking springs are fixedly connected between one end of each of the eight blocking positioning components and the outer wall of the eight bidirectional threaded rods.

[0006] Furthermore, eight buffer springs are fitted onto the upper and lower ends of the four positioning short columns and are fixedly connected to the upper and lower side walls of the mounting frame.

[0007] Furthermore, one end of each of the eight buffer springs abuts against the outer wall of both the high-voltage high-frequency circuit board and the low-voltage circuit board.

[0008] Furthermore, each of the eight blocking positioning discs has a limit slot on the side near the four positioning short posts.

[0009] Furthermore, each of the eight limiting slots has eight limiting blocks that are fixedly connected to the upper and lower side walls of the four positioning short columns.

[0010] Furthermore, the cross-sections of the inner sides of the eight limiting slots and the cross-sections of the eight limiting blocks are all T-shaped and compatible.

[0011] Furthermore, the eight blocking springs are respectively sleeved on the corresponding positions of the outer wall surfaces of the four limiting slide rods.

[0012] Furthermore, the outer walls of the left and right ends of the four bidirectional threaded rods are respectively provided with threads in opposite directions and are threadedly connected to one end of the eight adjusting slide plates.

[0013] Furthermore, an adjustment knob is fixedly installed on the middle of the outer wall surface of each of the four bidirectional threaded rods.

[0014] This utility model provides a novel mixed-voltage high-frequency circuit board. It has the following beneficial effects:

[0015] 1. This novel mixed-voltage high-frequency circuit board, through the setting of a positioning mechanism, allows for operation by rotating the adjustment knob to drive the bidirectional threaded rod, forcing the two adjusting slide plates threaded to the bidirectional threaded rod to move away from each other along the outer wall of the corresponding limit slide rod. The two adjusting slide plates, through two blocking springs, push the two blocking positioning components and the two blocking positioning discs away from each other, releasing the contact between the two blocking positioning discs and one end of the corresponding two positioning short pillars. Similarly, rotating the remaining three bidirectional threaded rods releases the contact between the eight blocking positioning discs and the upper and lower ends of the four positioning short pillars, facilitating the installation and removal of high-voltage high-frequency circuit boards and low-voltage circuit boards on the mounting frame. When there are many workers, the four blocking positioning components on the same side can be pulled outward to stretch the four blocking springs and move the four blocking positioning discs away from one end of the four positioning short pillars, thus enabling the installation and removal of high-voltage high-frequency circuit boards and low-voltage circuit boards on the mounting frame. The above operation is simple and practical, and the structure is reasonable and compact, allowing the equipment to be operated by a single person while retaining the original multi-person operation mode, improving the convenience and practicality of the equipment.

[0016] 2. This novel mixed-voltage high-frequency circuit board, by setting a limiting block, allows one end of the positioning short column to engage with the limiting slot on the corresponding blocking positioning plate through the limiting block, thereby enhancing the connection between the blocking positioning plate and the positioning short column and improving the stability of the equipment structure.

[0024] A novel hybrid voltage high-frequency circuit board, such as Figure 1-4 As shown, the system includes a mounting frame 10 and a high-voltage high-frequency circuit board 13 and a low-voltage circuit board 14 respectively disposed on the upper and lower sides of the mounting frame 10. Four U-shaped support feet 11 are symmetrically welded to the left and right sides of the mounting frame 10. Four positioning short posts 12 are disposed at the four corners of the mounting frame 10, penetrating the four corners of both the high-voltage high-frequency circuit board 13 and the low-voltage circuit board 14. Eight buffer springs 15 are fixedly connected to the upper and lower walls of the mounting frame 10 at their upper and lower ends. One end of each buffer spring 15 abuts against the outer wall of both the high-voltage high-frequency circuit board 13 and the low-voltage circuit board 14. Four sets of mounting brackets 16 are fixedly mounted at the front and rear ends of the upper and lower walls of the mounting frame 10. Positioning mechanisms are provided on the four sets of mounting brackets 16. The positioning mechanisms include four limiting slide rods 17 fixedly connected to the four sets of mounting brackets 16 and four bidirectional threaded rods 24 rotatably connected to the four sets of mounting brackets 16. Eight blocking positioning elements 18 are slidably connected to the outer wall of the four limiting slide rods 17. One end of the positioning member 18 is fixedly connected to eight blocking positioning discs 19 that abut against the upper and lower ends of the four positioning short posts 12. Each of the eight blocking positioning discs 19 has a limit slot 21 on the side near the four positioning short posts 12. Inside the eight limit slots 21, eight limit blocks 20 are fixedly engaged with corresponding positions on the upper and lower side walls of the four positioning short posts 12. The cross-sections of the inner sides of the eight limit slots 21 and the cross-sections of the eight limit blocks 20 are all T-shaped and compatible. The left and right ends of the four bidirectional threaded rods 24 are threaded together. There are eight adjusting slide plates 22 that are slidably connected to the outer walls of the four limiting slide rods 17. One end of the eight blocking positioning parts 18 is fixedly connected to the outer wall of the eight bidirectional threaded rods 24. The eight blocking springs 23 are respectively sleeved on the corresponding positions of the outer wall of the four limiting slide rods 17. The outer walls of the left and right ends of the four bidirectional threaded rods 24 are respectively provided with threads in opposite directions and are threadedly connected to one end of the eight adjusting slide plates 22. Adjusting knobs 25 are fixedly installed in the middle of the outer wall of the four bidirectional threaded rods 24.

[0025] The working principle of this utility model is as follows: In use, rotating the adjustment knob 25 drives the bidirectional threaded rod 24 to rotate, forcing the two adjusting slide plates 22, which are threadedly connected to the bidirectional threaded rod 24, to move away from each other along the outer wall surface of the corresponding limit slide rod 17. The two adjusting slide plates 22 push the two blocking positioning parts 18 and the two blocking positioning discs 19 away from each other through the two blocking positioning discs 19, releasing the contact operation between the two blocking positioning discs 19 and one end of the corresponding two positioning short posts 12. Similarly, rotating the remaining three bidirectional threaded rods 24 can release the contact between the eight blocking positioning discs 19 and the upper and lower ends of the four positioning short posts 12, thus facilitating the installation and removal of the high-voltage high-frequency circuit board 13 and the low-voltage circuit board 14 on the mounting frame 10. When there are many staff members, the four blocking positioning pieces 18 on the same side can be pulled outward to stretch the four blocking springs 23 and drive the four blocking positioning discs 19 away from one end of the four positioning short columns 12. This allows for the installation and removal of the high-voltage high-frequency circuit board 13 and the low-voltage circuit board 14 on the mounting frame 10. The above operation is simple and practical, and the structure is reasonable and compact, enabling the equipment to be operated by a single person while retaining the original multi-person operation mode, thus improving the convenience and practicality of the equipment. One end of the positioning short column 12 is engaged with the limiting slot 21 on the corresponding blocking positioning disc 19 through the limiting block 20 on it, which strengthens the connection between the blocking positioning disc 19 and the positioning short column 12 and improves the stability of the equipment structure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
