In the figure: 1. a base; 2. a circular turntable; 3. a screw hole; 4. a pull rod; 5. a chuck; 6. a sponge cushion; 7. fixing grooves; 8. and (4) anti-skid lines.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The PCB tester convenient to operate shown in figure 1 comprises a base 1, wherein the base is a base of the whole tester, and the bottom of the base is provided with a non-slip mat, so that the stability of the base can be improved.
Be provided with the circular revolving stage 2 of rotation axis perpendicular to base upper surface on the base, circular revolving stage is arranged in the circular recess that corresponds to seting up on the base, and the bottom of circular recess is provided with the carousel, and the rotation axis of carousel coincides with the rotation axis of circular revolving stage, and circular revolving stage passes through the carousel and connects with the base is rotatory, makes circular revolving stage obtain rotatory ability, when using, can rotate circular revolving stage, makes the rotatory different angle of PCB board, is convenient for test it in position and the angle of difference.
In addition, a bearing can be arranged between the circular turntable and the base, so that the rotating effect can be further ensured, and the bearing can seal a hole between the circular turntable and the base.
The part of the circular turntable, which protrudes out of the upper surface of the base, is provided with anti-slip stripes 8, the anti-slip stripes surround the side surface of the circular turntable for a circle, so that the friction force between the circular turntable and a human hand is increased, and the circular turntable is easier to rotate.
The side of the base is provided with a screw hole 3 vertical to the side of the circular rotary table, the screw hole is internally meshed with a rotation stopping bolt, the end part of the rotation stopping bolt can be supported on the side of the circular rotary table along with the rotation of the rotation stopping bolt and can be supported on the circular rotary table after being supported on the circular rotary table, the friction force between the rotation stopping bolt and the circular rotary table is increased, so that the rotation stopping effect can be achieved on the circular rotary table, the circular rotary table can be kept at a certain rotation angle, and the test on a PCB (printed circuit board) cannot be influenced due to the fact that the circular rotary table is.
The part of the circular turntable, which protrudes out of the upper surface of the base, is provided with a clamping device for fixing the PCB. The clamping device comprises two spring clamps which are symmetrical to each other by using a circular turntable, each spring clamp comprises a pull rod 4 and a chuck 5, the pull rod of each spring clamp is two, and the two pull rods jointly fix one chuck. The pull rod is arranged in a slide way hole correspondingly formed in the circular rotary table, a slide rail is arranged in the slide way hole, the slide rail is in sliding fit with the pull rod, and a spring is connected between the pull rod in the slide way hole and the circular rotary table.
