[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Please refer to Figures 1-5 , a circuit board detection fixture that is convenient to use, including a detection machine body 1. A support platform 2 is fixedly connected to the side wall of the detection machine body 1. Two support sliding grooves 3 are opened on the side wall of the support platform 2. A support sliding block 4 is slidably connected to the inner wall of the support sliding groove 3. A chute opening is opened on the upper surface of the support sliding block 4. A slide bar 5 is slidably connected to the inner wall of the chute opening. A support spring 6 is sleeved on the side wall of the slide bar 5. A support side plate 7 is fixedly connected to the upper surface of the slide bar 5. A lifting device is provided between the two support side plates 7. A fixing device is provided on one side of the slide bar 5.

[0022] It can be seen from the above structure that by setting the detection machine body 1, support platform 2, support sliding groove 3, support sliding block 4, chute opening, slide bar 5, support spring 6, support side plate 7, lifting device and fixing device in cooperation; when the circuit board needs to be detected, the fixing device is turned on, and the support side plate 7 under the pressing plate of the detection machine body 1 can be pulled, so that the support side plate 7 drives the support sliding block 4 to slide out from under the pressing plate of the detection machine body 1 along the support sliding groove 3 through the slide bar 5, which is convenient to place the circuit board on the support side plate 7. Then, the support side plate 7 is pushed into the detection machine body 1 under the pressing plate, and the fixing device is used to fix the support sliding block 4, and the circuit board detection can be carried out. When the support side plate 7 drives the support sliding block 4 to slide to the bottom of the support sliding groove 3, the lifting device will lift the circuit board in the support side plate 7, which is convenient for the staff to take.

[0023] Further, the lifting device includes two sets of T-shaped chutes 8 opened on the side walls of two adjacent support side plates 7. The side walls of the T-shaped chutes 8 are both slidably connected with T-shaped sliders 9. The side wall of the T-shaped slider 9 is fixedly connected with a lifting side plate 10. The bottom surface of the lifting side plate 10 is fixedly connected with two first magnets 12. On the upper surface of the support platform 2 symmetric to the first magnet 12, a second magnet 11 is fixedly connected. The first magnet 12 and the second magnet 11 are arranged to repel each other. By setting the two sets of T-shaped chutes 8, T-shaped sliders 9, lifting side plates 10, first magnets 12 and second magnets 11 to cooperate with each other, when it is necessary to take out the circuit board in the support side plate 7, first turn on the fixing device, and then pull the support side plate 7, so that the support side plate 7 drives the support slider 4 to slide along the support chute 3 to the bottom of the support chute 3 through the slide bar 5. When the support slider 4 slides to the bottom of the support chute 3, the first magnet 12 fixedly connected to the bottom surface of the lifting side plate 10 will be perpendicular to the second magnet 11. Because the second magnet 11 repels the first magnet 12 and the second magnet 11 has sufficient repulsive magnetic force, the second magnet 11 will push the first magnet 12 to drive the lifting side plate 10 to slide up along the T-shaped chute 8 through the T-shaped slider 9. At the same time, the two lifting side plates 10 will drive the circuit board to rise, which is convenient for taking the circuit board. After taking out the circuit board, the support side plate 7 can be slightly pushed forward to make the first magnet 12 out of the magnetic force range of the second magnet 11. At this time, the lifting side plate 10 will descend to form a clamping space with the support side plate 7, which is convenient for placing the circuit board and enhances the use convenience.

[0024] Further, the fixing device includes a support rod 13 fixedly connected to one end of the support slider 4. The upper surface of the support rod 13 is fixedly connected with a spring chamber 14. The inner wall of the spring chamber 14 is slidably connected with a T-shaped fixing pin 16. The two ends of the T-shaped fixing pin 16 extend out of the spring chamber 14. A fixing spring 15 is sleeved on the side wall of the T-shaped fixing pin 16 inside the spring chamber 14. One end of the fixing spring 15 is fixedly connected with the side wall of the T-shaped fixing pin 16, and the other end of the fixing spring 15 is fixedly connected with the inner wall of the spring chamber 14. An insertion slot 18 is opened on the side wall of the support platform 2 below the T-shaped fixing pin 16. By using the support rod 13, spring chamber 14, T-shaped fixing pin 16, fixing spring 15 and insertion slot 18 in cooperation, pulling the T-shaped fixing pin 16 makes the T-shaped fixing pin 16 squeeze the fixing spring 15 out of the insertion slot, and then the T-shaped fixing pin 16 can be pulled outwards. Then the T-shaped fixing pin 16 will drive the support slider 4 to slide along the support chute 3 through the support rod 13. When the T-shaped fixing pin 16 is on one side of the insertion slot 18, release the T-shaped fixing pin 16, and the fixing spring 15 will push the T-shaped fixing pin 16 to automatically slide into the insertion slot 18. The operation is simple and convenient.

[0025] Furthermore, the first magnets 12 and the second magnets 11 on the front side are arranged in a staggered manner with the first magnets 12 and the second magnets 11 on the rear side; the staggered design enables the first magnet 12 on the rear side to only react to the second magnet 11 on the same vertical line on the rear side, and will not react to the first magnet 12 passing through the second magnet 11 on the rear side, facilitating the simultaneous upward movement of the lifting side plates 10.

[0026] Furthermore, a shock-absorbing rubber pad 19 is fixedly connected to the bottom surface of the T-shaped chute 8; by providing the shock-absorbing rubber pad 19, the vibration generated when the T-shaped slider 9 slides down is reduced, improving the safety of use.

[0027] Furthermore, a circular pull handle 17 is fixedly connected to the top surface of the T-shaped fixing pin 16; by providing the circular pull handle 17, the circular pull handle 17 can be pulled to drive the T-shaped fixing pin 16 to rise or fall, facilitating the pulling of the T-shaped fixing pin 16.

[0028] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
