[0026] The following will describe in detail some embodiments of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0027] Please refer to Figures 1-6 , embodiments of the present utility model provide a magnetic adsorption type clamping and locking mechanism for circuit board testing, including a base 10, an adjusting mechanism 20 is installed at the upper end near one side of the base 10, and a sub - part clamping mechanism for clamping a sub - board is installed at the upper end of the adjusting mechanism 20.

[0028] Among them, the sub - part clamping mechanism includes a pair of adjusting rails 40 located above the adjusting mechanism 20, and an adjusting plate 43 is horizontally slidably connected between the pair of adjusting rails 40.

[0029] Positioning bolts 41 are provided at both sides of the adjusting plate 43 close to the two sides. The positioning bolts 41 slide in the adjusting rails 40, and at the same time, the positioning bolts 41 penetrate through the adjusting plate 43 and are threadedly connected with the tightening nuts 42. Therefore, after loosening the positioning bolts 41, the adjusting plate 43 can slide back and forth on the adjusting rails 40, realizing the movement of the overall clamping mechanism on the Y - axis. After sliding to a suitable position, tightening the positioning bolts 41 can fix the adjusting plate 43.

[0030] In order to fix the sub - board, moving blocks 46 are slidably connected to both ends of the adjusting plate 43. Two groups of symmetric slide bars 47 are provided at the bottom of the moving blocks 46. The slide bars 47 are correspondingly slidably connected with two groups of adjusting slots 44 opened on the adjusting plate 43. At the same time, slide holes are opened at the bottom of the moving blocks 46, and the adjusting plate 43 is located in the slide holes to realize the movement of the moving blocks 46.

[0031] In addition, a knob bolt 48 is threadedly connected to the bottom of the moving block 46. One end of the knob bolt 48 is inserted and fitted with a groove 49 opened at the bottom of the adjusting plate 43. After loosening the knob bolt 48, the moving block 46 can slide. After the moving block 46 slides to a suitable position, the knob bolt 48 is tightened so that the knob bolt 48 enters the corresponding groove 49 to fix the moving block 46.

[0032] Since a scale line 45 is provided on one side of the adjusting plate 43, when adjusting the width of the two moving blocks 46, the width refers to the scale line 45 and is preferably centered.

[0033] One side of each of the two moving blocks 46 is respectively connected to two positioning bars 50. A placing plate one 60 is connected between the two positioning bars 50. The placing plate one 60 is used to place the sub-board. At the same time, the placing plate one 60 can be magnetized. After the position of the sub-board is adjusted, magnetization is performed to lock the sub-board.

[0034] At the same time, a second slot 51 is opened inside the positioning bar 50. The side of the placing plate one 60 is snap-fitted with the second slot 51, which is convenient for disassembling the placing plate one 60 and adjusting its position.

[0035] As Figure 1 shown, a support rod 30 is installed at the upper end near the other side of the base 10. The support rod 30 supports the support plate 31. A main part clamping mechanism for clamping the main board is installed on the upper side of the support plate 31.

[0036] The main part clamping mechanism includes two groups of symmetric positioning blocks 32 on the upper side of the support plate 31. A placing plate two 70 is installed between the two groups of positioning blocks 32. A first slot 33 is opened inside the positioning block 32. The side of the placing plate two 70 is snap-fitted with the first slot 33, which is convenient for disassembling and assembling the position of the placing plate two 70.

[0037] A clamp 71 is installed on the upper side of the placing plate two 70, and the main board can be placed in the clamp 71 to improve the stability of the main board.

[0038] At the same time, a connecting plate 72 is provided on one side of the clamp 71. A fixing bolt 74 is threadedly connected to one side of the connecting plate 72. The lower end of the fixing bolt 74 is rotatably connected to a fixing plate 73. After rotating the fixing bolt 74, the fixing plate 73 is pushed downward. When the fixing plate 73 is in contact with the sub-board, the sub-board is fixed.

[0039] In summary, the working principle of a magnetic adsorption type clamping and locking mechanism for circuit board testing in an embodiment of the present utility model is as follows: When the sub-board is placed, the left and right and front and back positions of the sub-board can be adjusted through the sub-part clamping mechanism. Then the main board is fixed in the clamp 71. After adjusting the positions of the sub-board and the main board, the magnetic adsorption switch of the entire device is turned on to lock the sub-board.

[0040] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
