Description

Technical Field

[0001] This invention relates to the field of circuit board processing, and more particularly to a circuit board insertion rack. Background Technology

[0002] Circuit boards can be broadly classified into three categories based on the number of layers: single-sided, double-sided, and multi-layer circuit boards. First, there are single-sided circuit boards. In the most basic type, components are concentrated on one side, while conductors are concentrated on the other. Because the conductors only appear on one side, this type of circuit board is called a single-sided circuit board. In existing technology, a board mounting bracket is used to hold circuit boards. Patent application number CN202022687453.X discloses a circuit board mounting bracket, which includes a fixing plate. A fixing block is fixed to the upper surface of the fixing plate, and V-shaped fixing grooves are evenly distributed on the fixing block. Vertical posts are fixed to the four corners of the upper surface of the fixing plate. Fixing rods are provided between the posts on both sides of the fixing plate, passing through the posts and rotatably connected to them. A turntable is also fixed to one side of the fixing rod, and fixing holes are evenly distributed through the turntable. Limiting holes are also provided on the posts. Handles are fixed to the turntable. Limiting blocks are evenly distributed on the fixing rods. The cross-section of the limiting blocks is fan-shaped, and the width of the arc-shaped end face of the limiting block gradually increases from one side to the other. The circuit board to be placed is placed in the insertion rack, and the bottom of the circuit board is fixed in the fixing slot of the fixing block. The two sides of the circuit board are fixed between two adjacent limiting blocks to secure the circuit board. Although this type of insertion rack can accommodate a large number of circuit boards, when the batch of the same circuit board is relatively small, and another circuit board has different external dimensions, a regular insertion rack cannot hold both types of circuit boards at once. Two corresponding insertion racks are required, which will lead to a shortage of insertion racks and seriously affect production capacity and work efficiency.

[0003] This invention was proposed in response to the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a circuit board insertion rack.

[0005] This invention can be achieved through the following technical solutions:

[0006] This invention discloses a circuit board insertion bracket, comprising a positioning plate and a limiting plate. Multiple positioning slots are fixed on both the positioning plate and the limiting plate. Multiple support tubes are fixed on the positioning plate. Support rods are fixed on the limiting plate at positions corresponding to the support tubes. The ends of the support rods are disposed within the corresponding support tubes and slidably connected to them. Threaded tubes are fixed at the ends of the support tubes, and threaded rods are threaded onto the threaded tubes. A supporting plate is disposed between the positioning plate and the limiting plate. Multiple limiting slots are fixed at both ends of the supporting plate. Slip rings are fixed on the supporting plate at positions corresponding to the support tubes. The support tubes pass through the slip rings and are slidably connected to them. Support slots are fixed on both the positioning plate and the limiting plate, and support slots are also fixed on both sides of the supporting plate. Adjust the distance between the support plate and the positioning plate according to the required size of the circuit board. The position of the support plate is adjusted by sliding the sliding ring on the support plate onto the support tube. Similarly, adjust the distance between the limiting plate and the support plate according to the size of the second type of circuit board. This is achieved by inserting a support rod into the support tube and sliding it to adjust the distance between the limiting plate and the support plate. After the limiting plate is adjusted to the appropriate position, rotate the screw. Because the screw is threadedly connected to the threaded tube, it moves on the threaded tube as it rotates. The bottom of the screw presses against the support rod, fixing the support rod to the support tube. After the support rod is fixed, the first circuit board is inserted between the positioning plate and the support plate. Both ends of the circuit board are respectively locked in the positioning slot and the limiting slot, and the bottom of the circuit board is limited and supported by the support slot, thus fixing the circuit board. The second circuit board is fixed between the limiting plate and the support plate. Both ends of the circuit board are respectively locked in the positioning slot of the limiting plate and the limiting slot of the support plate, and the bottom of the circuit board is limited and supported by the support slot, thus fixing the second circuit board. This device can meet the fixing requirements of circuit boards of different sizes and can fix two sizes of circuit boards at the same time.

[0007] Preferably, a threaded block is also fixed on the slip ring, and each threaded block is provided with a bolt that is threadedly connected to the threaded block. After the support plate is adjusted to a suitable position, the bolt is rotated, and the bottom of the bolt is pressed against the support tube, thus fixing the slip ring to the support tube.

[0008] Preferably, both the positioning plate and the limiting plate are equipped with handles. The handles make it easier to move the device.

[0009] Compared with existing technologies, the present invention has the following advantages:

[0010] This device can meet the requirements for fixing circuit boards of different sizes, and can fix two sizes of circuit boards at the same time. Attached Figure Description

[0015] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0016] Example 1:

[0017] like Figure 1As shown, this embodiment discloses a circuit board insertion bracket, including a positioning plate 1 and a limiting plate 2. Multiple positioning slots 3 are fixed on both the positioning plate 1 and the limiting plate 2. Multiple support tubes 4 are fixed on the positioning plate 1. Support rods 5 are fixed on the limiting plate 2 at positions corresponding to the support tubes 4. The ends of the support rods 5 are all disposed within the corresponding support tubes 4 and slidably connected to the support tubes 4. Threaded tubes 6 are fixed at the ends of the support tubes 4, and screws 7 are threadedly connected to the threaded tubes 6. A support plate 8 is disposed between the positioning plate 1 and the limiting plate 2. Multiple limiting slots 9 are fixed at both ends of the support plate 8. Slip rings 10 are fixed on the support plate 8 at positions corresponding to the support tubes 4. The support tubes 4 pass through the slip rings 10 and slidably connect to the slip rings 10. Support slots 13 are fixed on both the positioning plate 1 and the limiting plate 2, and support slots 13 are also fixed on both sides of the support plate 8. The distance between the support plate 8 and the positioning plate 1 is adjusted according to the required size of the circuit board. The position of the support plate 8 is adjusted by sliding the slip ring 10 on the support tube 4. The distance between the limiting plate 2 and the support plate 8 is also adjusted according to the size of the second type of circuit board. The distance between the limiting plate 2 and the support plate 8 is adjusted by inserting the support rod 5 into the support tube 4 and sliding it. After the limiting plate 2 is adjusted to the appropriate position, the screw 7 is rotated. Since the screw 7 is threadedly connected to the threaded tube 6, when the screw 7 rotates, it moves on the threaded tube 6. After the bottom of the screw 7 is pressed against the support rod 5, the support rod 5 and the support tube 4... After fixing the support rod 5, the first circuit board is inserted between the positioning plate 1 and the support plate 8. The two ends of the circuit board are respectively locked in the positioning slot 3 and the limiting slot 9, and the bottom of the circuit board is limited and supported by the support slot 13, thus fixing the circuit board. The second circuit board is fixed between the limiting plate 2 and the support plate 8. The two ends of the circuit board are respectively locked in the positioning slot 3 of the limiting plate 2 and the limiting slot 9 of the support plate 8, and the bottom of the circuit board is limited and supported by the support slot 13, thus fixing the second circuit board. This device can meet the fixing requirements of circuit boards of different sizes and can fix two sizes of circuit boards at the same time.

[0018] The slip ring 10 is also fixed with a threaded block, and each threaded block is provided with a bolt 11 that is threadedly connected to the threaded block. After the support plate 8 is adjusted to a suitable position, the bolt 11 is rotated. The bottom of the bolt 11 is squeezed against the support tube 4, which fixes the slip ring 10 to the support tube 4.

[0019] Example 2:

[0020] like Figure 2 As shown, this embodiment discloses a circuit board insertion rack. Based on the structure and principle of embodiment 1, both the positioning plate 1 and the limiting plate 2 of this embodiment are fixed with handles 12. The handles 12 make it easier to move this device.
