Technical Field

[0001] The utility model relates to the technical field of testing fixtures, in particular to a flip-type single-board testing fixture. Background Art

[0002] A fixture is a large category of tools for carpentry, ironwork, fitter, machinery, electronic control and other handicrafts. It is mainly used as a tool to assist in controlling position or movement. Fixtures can be divided into three categories: process assembly fixtures, project test fixtures and circuit board test fixtures.

[0003] The test fixture can be used to detect the test performance of a module or a single board. In the process of testing a module or a single board to be tested, it is usually necessary to connect an auxiliary single board to the workpiece to be tested.

An adapter, the adapter is fixed on the body, and the adapter can be electrically connected to the test probe. And an auxiliary single board, the auxiliary single board is detachably connected to the adapter. By detachably connecting the auxiliary single board to the adapter, the installation and removal of the auxiliary single board on the adapter can be quickly achieved, which plays a role in improving the replacement speed of the auxiliary single board, avoiding the delay of the test of the single board to be tested due to a long waiting time, compressing the replacement time of the auxiliary single board as much as possible, and maximizing the working efficiency of the test fixture. In addition, it can effectively avoid the damage of the auxiliary single board during the binding installation and forced disassembly process, thereby reducing the testing cost of the test fixture.

[0005] During the use of the existing single board test fixture, the staff needs to press the single board on the surface of the test material, but the process of pressing the single board on the surface of the tested material is cumbersome and not convenient and fast enough. Therefore, we propose a flip-type single board test fixture to solve the above-mentioned problems. Utility Model Content

[0025] Embodiment 1, refer to Figures 1-4 In this embodiment, in order to solve the problem that the existing single board test fixture needs to press the single board on the surface of the test material during use, but the process of pressing the single board on the surface of the tested material is relatively cumbersome and not convenient and fast enough, the utility model discloses a flip-top single board test fixture.

[0026] It includes a base 1, a support base 2 is fixedly installed on the top of the base 1, a single board body 3 is movably hingedly arranged on the front surface of the support base 2, a first connecting plate 4 is fixedly installed on the left and right sides of the single board body 3, a second connecting plate 5 is fixedly installed on both sides of the support base 2, a first connecting rod 6 is movably hingedly arranged on the surface of the second connecting plate 5, the other end of the first connecting rod 6 is movably hingedly arranged at the bottom of the first connecting plate 4, a second connecting rod 7 is movably hingedly arranged on the surface of the second connecting plate 5, a third connecting rod 8 is movably hingedly arranged on the surface of the first connecting plate 4, the second connecting rod 7 is hingedly arranged with the third connecting rod 8, and the second connecting rod 7 is hingedly arranged with the first connecting rod 6.

[0027] A pressing plate 9 is fixedly mounted on the top of the rear side of the single board body 3 , and two test probes 10 are fixedly mounted on the front side of the single board body 3 .

[0028] The specific working principle is: by setting the single board body 3, the staff places the material to be tested on the surface area of ​​the base 1, and then uses the pressing plate 9 to flip down the single board body 3. The single board body 3 moves on the support seat 2 in a stable trajectory through the first connecting rod 6, the second connecting rod 7 and the third connecting rod 8 on the surface, so that the test probe 10 is accurately placed on the test area, so that the material test can be quickly carried out by flip-type pressing.

[0029] Example 2, refer to Figures 1-4 In order to solve the problem that the existing test fixture is not firmly fixed and affects the test results, based on the same concept as the above-mentioned embodiment 1, the flip-type single-board test fixture also includes:

[0030] A movable groove 11 is provided on the surface of the base 1 , a fixed plate 12 is fixedly installed in the middle of the inner cavity of the movable groove 11 , and a bidirectional lead screw 13 is rotatably connected between the inner walls on the left and right sides of the inner cavity of the movable groove 11 .

[0031] The bidirectional lead screw 13 penetrates the surface of the fixed plate 12 and is rotatably connected to the surface of the fixed plate 12 . The left end of the bidirectional lead screw 13 penetrates the left side of the base 1 and a knob 14 is fixedly installed on the left end of the bidirectional lead screw 13 .

[0032] The left and right sections of the bidirectional lead screw 13 are both threadedly movably connected with sliders 15 , and the two sliders 15 are both slidably arranged inside the movable groove 11 .

[0033] An L-shaped limiting plate 16 is fixedly mounted on the top of the two sliding blocks 15 .

[0034] A positioning block 17 is fixedly mounted on the top of the base 1 , and a spring latch 18 is inserted into the inner cavity of the positioning block 17 .

[0036] The specific working principle is: by setting the knob 14, the staff places the material to be tested on the base 1, and then rotates the knob 14 according to the size of the material to be tested. The rotation of the knob 14 drives the two-way screw 13 to rotate, and the rotation of the two-way screw 13 drives the left and right sections of the sliders 15 to move closer to each other, that is, the limit plates 16 move closer to each other to clamp and limit the material to be tested. By pulling the handle 20 outward and then releasing it, the spring pin 18 is affected by itself and drives the positioning plate 19 to press against the front side of the material to be tested, thereby cooperating with the limit plate 16 to clamp and limit the material to be tested.
