Description

Technical Field

[0001] The present invention relates to the field of circuit board processing, and particularly to a bracket for circuit board processing. Background Art

[0002] A circuit board is an important electronic component and a support for electronic components. During the processing of a circuit board, a bracket is required to hold the circuit board; most of the existing brackets for circuit board processing are fixedly installed on the operating table. The overall structure of the common bracket is fixed and cannot be flexibly adjusted. Since the multi-layer circuit board brackets are generally connected and fixed by screws between each layer of trays and the support columns, the disassembly and assembly operations between the trays are relatively inconvenient. Summary of the Invention

[0003] The purpose of the present invention is to provide a bracket for circuit board processing.

[0004] The technical problems of the present invention are mainly solved by the following technical solutions:

[0005] A bracket for circuit board processing, comprising an upper disk body and a lower disk body:

[0006] Four groups of vertex regions at the bottom of the upper disk body are each provided with a screw rod, on which a screw tube is screwed, and the screw tube is fixed on the side wall of the lower disk body through a bearing. An arc-shaped plate buckling on the screw tube is provided at the top of the side wall of the lower disk body. A rectangular notch is provided at the top of the arc-shaped plate. An operation opening corresponding to the rectangular notch is provided on the side wall of the screw tube. A limiting rod is arranged in the operation opening and the rectangular notch, and one end of the limiting rod is fixed in the opening of the screw tube through a rotating shaft. A spring connected to the inner side wall of the screw tube is obliquely arranged at the top of the limiting rod;

[0007] An arc-shaped magnetic plate located directly above the operation opening is further arranged in the screw tube, and the top of the magnetic plate is connected to a fixed block in the screw tube through a telescopic rod.

[0008] Preferably, support plates are arranged on both side walls inside the upper disk body and the lower disk body, and U-shaped notches for fixing the ends of the circuit board are evenly arranged at the top of the support plates.

[0009] Preferably, the length of the limiting rod is less than the distance between the rotating shaft and the operation opening, and the diameter of the limiting rod is adapted to the width of the rectangular notch and the operation opening.

[0010] Preferably, a stud is arranged at the bottom of the lower disk body, a counterweight seat is arranged on the stud, and a threaded hole screwed with the stud is arranged on the counterweight seat. Supporting feet for suspending the lower disk body are further arranged at the bottom of the lower disk body, and the height of the supporting feet is greater than the length of the stud and the thickness of the counterweight seat.

[0011] Preferably, the outer side wall of the solenoid is a smooth structure, and a thread screwed with the screw rod is provided on the inner side wall of the solenoid.

[0012] Preferably, a groove is provided on the inner side wall of the solenoid, and one end of the spring is fixedly connected to the side wall of the groove.

[0013] The beneficial effects of the present invention are as follows: The present invention prevents the solenoid from rotating by means of the rectangular notch against the limiting rod, so that the solenoid will not rotate on the screw rod, thereby ensuring the distance between the upper disc body and the lower disc body; and when it is necessary to adjust the distance between the upper disc body and the lower disc body, only need to rotate the limiting rod to rotate around the rotating shaft while compressing the spring. When the limiting rod slides into the inner opening of the solenoid through the operation opening, then multiple people cooperate to rotate the solenoid so that it rotates in the bearing and also rotates on the screw rod to expand or contract the screwed area between the screw rod and the solenoid, thereby changing the distance between the upper disc body and the lower disc body, or making the screw rod slide out of the solenoid to realize the separation of the upper disc body and the lower disc body. In the above process, since the rectangular notch no longer resists the limiting rod, components such as the arc-shaped plate will not affect the rotation of the solenoid.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions of the present invention will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0019] A bracket for circuit board processing includes an upper disc body 1 and a lower disc body 2:

[0020] The four groups of top corner areas at the bottom of the upper disk body 1 are all provided with screw rods 3, wherein a screw tube 4 is screwed on the screw rods 3, and the screw tube 4 is fixed to the side wall of the lower disk body 2 through a bearing 5, and an arc plate 6 buckled on the screw tube 4 is provided at the top of the side wall of the lower disk body 2, wherein a rectangular notch 7 is provided at the top of the arc plate 6, and an operation opening 8 corresponding to the rectangular notch 7 is provided on the side wall of the screw tube 4, wherein a limiting rod 9 is provided in the operation opening 8 and the rectangular notch 7, and one end of the limiting rod 9 is fixed in the opening of the screw tube 4 through a rotating shaft 10, and a spring 11 connected to the inner side wall of the screw tube 4 is also obliquely provided on the top of the limiting rod 9, and a groove 20 is provided on the inner side wall of the screw tube 4, wherein one end of the spring 11 is fixedly connected to the side wall of the groove 20;

[0021] The spiral tube 4 is also provided with an arc-shaped magnetic plate 12 located just above the operation opening 8 , wherein the top end of the magnetic plate 12 is connected to a fixed block 14 in the spiral tube 4 via a telescopic rod 13 .

[0022] In this embodiment, support plates 15 are provided on both side walls of the upper plate 1 and the lower plate 2, wherein U-shaped notches 16 for fixing the ends of the circuit board are evenly provided on the top of the support plates 15. By inserting the two ends of the circuit board into the corresponding U-shaped notches 16, the circuit board is fixed in the upper plate 1 and the lower plate 2 in an orderly manner.

[0023] In this embodiment, the length of the limiting rod 9 is smaller than the distance between the rotating shaft 10 and the operating opening 8, wherein the diameter of the limiting rod 9 is adapted to the width of the rectangular notch 7 and the operating opening 8. Thus, after the limiting rod 9 rotates with the rotating shaft 10 as the center, it can slide into the inner opening of the screw tube 4 through the operating opening 8.

[0024] like Figure 1 As shown, a stud 17 is provided at the bottom of the lower plate 2, wherein a counterweight seat 18 is provided on the stud 17, and a screw hole is provided on the counterweight seat 18 to be screwed with the stud 17. A support leg 19 is also provided at the bottom of the lower plate 2 to suspend it, wherein the height of the support leg 19 is greater than the length of the stud 17 and the thickness of the counterweight seat 18. The overall weight of the device is increased by the counterweight seat 18 to lower its center of gravity, thereby effectively improving its stability.

[0025] In this embodiment, the outer wall of the spiral tube 4 is a smooth structure, wherein the inner wall of the spiral tube 4 is provided with a thread that is threadedly connected to the screw rod 3 .

[0026] The working principle of the present invention is as follows: Figure 1 , 2 As shown, the spring 11 stretches and pushes the limit rod 9 to rotate with the rotating shaft 10 as the center, so that it slides out of the operation opening 8 and is embedded in the corresponding rectangular notch 7. The rectangular notch 7 abuts against the limit rod 9 to prevent the screw tube 4 from rotating, so that the screw tube 4 will not rotate on the screw rod 3, thereby ensuring the spacing between the upper plate body 1 and the lower plate body 2;

[0027] When the distance between the upper plate body 1 and the lower plate body 2 needs to be adjusted, it is only necessary to rotate the limit rod 9 to make it rotate around the rotating shaft 10 as the center of the circle while compressing the spring 11. At this time, the magnetic plate 12 is magnetically connected to the inner wall of the screw tube 4 and will not move downward to block the operation opening 8, or the magnetic plate 12 is pushed upward to move it above the operation opening 8 to prevent it from blocking the operation opening 8. When the limit rod 9 slides into the inner opening of the screw tube 4 through the operation opening 8, the magnetic plate 12 can be pulled downward to move it downward to resist the top end of the limit rod 9 in the vertical state at this time, preventing it from sliding out through the operation opening 8 under the stretching force of the spring 11. At this time, people can operate the screw tube 4 very calmly;

[0028] Then, multiple people cooperate to rotate the screw tube 4 so that it rotates in the bearing 5 and also rotates on the screw rod 3 to expand or reduce the threaded connection area between the screw rod 3 and the screw tube 4, thereby changing the distance between the upper disk body 1 and the lower disk body 2, or making the screw rod 3 slide out of the screw tube 4 to realize the separation of the upper disk body 1 and the lower disk body 2. In the above process, under the premise that the rectangular notch 7 is lost to resist the limit rod 9, the arc plate 6 and other components will not affect the rotation of the screw tube 4. When it is necessary to prevent the screw tube 4 from rotating, the operating opening 8 is aligned with the rectangular notch 7. At this time, it is only necessary to squeeze the magnetic plate 12 upward to open the operating opening 8. Then, under the action of the loss of the magnetic plate 12, the spring 11 stretches and pushes the limit rod 9 to rotate with the rotating shaft 10 as the center. After the limit rod 9 slides out of the operating opening 8, it will be stuck in the corresponding rectangular notch 7, thereby achieving the purpose of preventing the screw tube 4 from rotating by resisting the limit rod 9 by the rectangular notch 7.

[0029] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
