Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] As attached Figures 1 to 5 The tooling rack shown includes a test cabinet 1 and a box 2. A base plate 3 is fixedly installed on the bottom wall of the box 2. A connecting plate 4 is fixedly installed between the test cabinet 1 and the box 2. A second unfolding plate 10 is slidably installed in the connecting plate 4, and a groove is opened at one end of the second unfolding plate 10 for pulling. The connecting plate 4 and the second unfolding plate 10 are fixedly connected by bolts. A first unfolding plate 5 is slidably installed in the base plate 3, and the base plate 3 and the first unfolding plate 5 are fixedly connected by bolts. Two support legs 11 are symmetrically rotatably connected to the bottom wall of the second unfolding plate 10. A limiting component is provided on the bottom wall of the second unfolding plate 10 to limit and fix the rotating support legs 11. A number of limiting holes 9 are equally spaced on the side walls of the first unfolding plate 5 and the second unfolding plate 10. A number of first marking lines 7 are equally spaced on the side walls of the first unfolding plate 5 and the second unfolding plate 10. A second marking line 8 is provided at one end of the base plate 3 and the connecting plate 4.
[0023] In use, the second unfolding plate 10 is first slid out of the connecting plate 4 through the groove at one end, so that the first marking line 7 on the side wall of the second unfolding plate 10 is aligned with the second marking line 8 at one end of the connecting plate 4. Then, the bolts screwed on the connecting plate 4 are rotated, and one end of the bolt can be moved and inserted into the limiting hole 9 on the second unfolding plate 10, thereby limiting and fixing the second unfolding plate 10. Next, the two support legs 11 are rotated, so that the support legs 11 unfold from the bottom wall of the second unfolding plate 10. Then, the two unfolded support legs 11 are limited and fixed by the limiting component on the bottom wall of the second unfolding plate 10. Then, the first unfolding plate 5 is slid out from the bottom plate 3, so that the first marking line 7 on the side wall of the first unfolding plate 5 is aligned with the second marking line 8 at one end of the connecting plate 4. After the second marking line 8 is aligned, rotate the bolts screwed on the base plate 3. At this time, one end of the bolt can be moved and inserted into the limiting hole 9 opened on the first unfolding plate 5 to complete the limiting and fixing of the first unfolding plate 5. The two support legs 11 on the bottom wall of the second unfolding plate 10 are in contact with the upper surface of the first unfolding plate 5. The second unfolding plate 10 is supported by the two support legs 11 in contact with the surface of the first unfolding plate 5, thereby completing the unfolding of the first unfolding plate 5 and the second unfolding plate 10. The unfolded first unfolding plate 5 and the second unfolding plate 10 can be used to place some connectors or toolboxes and other test tools when performing load tests on low-voltage electrical equipment. When not in use, the extended first unfolding plate 5 and the second unfolding plate 10 can be folded to avoid occupying a lot of space.
[0024] Example 2
[0025] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:
[0026] In a preferred embodiment, the limiting assembly includes a connecting hole 12, a limiting block 13, a movable plate 14, a fixed plate 15, a limiting rod 16, and a spring 17. First, a connecting hole 12 is formed on one end surface of each of the two second unfolding plates 10. Then, a fixed plate 15 is fixedly welded to the bottom wall of the second unfolding plate 10. A limiting rod 16 movably passes through the surface of the fixed plate 15, and one end of the limiting rod 16 is fixedly connected to the movable plate 14. Next, two limiting blocks 13 are symmetrically fixedly connected to the surface of the movable plate 14, engaging with the connecting hole 12. The cross-sections of the connecting hole 12 and the limiting block 13 are both square, allowing the limiting block 13 to fit precisely into the connecting hole 12. To complete the limiting and fixing of the support leg 11, a spring 17 is sleeved on the outside of the limiting rod 16, and the spring 17 is located between the moving plate 14 and the fixed plate 15. Furthermore, when limiting and fixing the rotating support leg 11, the moving plate 14 and the limiting block 13 set on the moving plate 14 are first pulled by the limiting rod 16. Then the support leg 11 is rotated, and then the limiting rod 16 is released. At this time, the spring 17 squeezes and pushes the moving plate 14 and the limiting block 13 set on the moving plate 14 toward the two support legs 11, and makes the two limiting blocks 13 respectively insert into the two connecting holes 12, thereby completing the limiting and fixing of the two support legs 11.
[0027] As a preferred embodiment, two casters 6 are symmetrically arranged on one side of the bottom wall of the test cabinet 1, and two casters 6 are symmetrically arranged on one side of the bottom wall of the first unfolding plate 5; furthermore, the entire device can be moved and adjusted by the arrangement of four casters 6.
[0028] In a preferred embodiment, a fitting groove 21 is provided on both sides of the first unfolding plate 5, and two fitting blocks 20 that are symmetrically fixedly welded to the inner sidewall of the bottom plate 3 and are limited and slidably connected to the fitting groove 21 are provided.
[0029] In a preferred embodiment, two cabinet doors 18 are connected to the surface of the test cabinet 1 by hinges, and two boxes doors 19 are connected to the surface of the box 2 by hinges. Each of the two cabinet doors 18 and the two boxes doors 19 is fixedly connected with a handle by screws. In use, the two cabinet doors 18 on the test cabinet 1 are opened, and the low-voltage electrical connection to be tested is placed inside for testing.
[0030] The working process of this utility model is as follows: First, when using the device, the second unfolding plate 10 is slid out of the connecting plate 4 through the groove at one end of the second unfolding plate 10, so that the first marking line 7 on the side wall of the second unfolding plate 10 is aligned with the second marking line 8 at one end of the connecting plate 4. Then, the bolts screwed on the connecting plate 4 can be rotated. At this time, one end of the bolt can be moved and inserted into the limiting hole 9 on the second unfolding plate 10, thereby limiting and fixing the second unfolding plate 10. Next, the limiting rod 16 pulls the moving plate 14 and the limiting block 13 on the moving plate 14 to release the limiting block 13 from limiting and fixing the support leg 11. Then, the two support legs 11 are rotated so that the support legs 11 unfold from the bottom wall of the second unfolding plate 10. Then, the limiting rod 16 is released. At this time, the spring 17 squeezes and pushes the moving plate 14 and the limiting block 13 on the moving plate 14 toward the two support legs 11, and makes them... Two limiting blocks 13 are respectively inserted into two connecting holes 12 to limit and fix the two support legs 11. Then, the first unfolding plate 5 is slid out from the base plate 3. Similarly, the first marking line 7 on the side wall of the first unfolding plate 5 is aligned with the second marking line 8 on one end of the base plate 3. Then, the bolts screwed on the base plate 3 are rotated. At this time, one end of the bolt can be moved and inserted into the limiting hole 9 opened on the first unfolding plate 5 to complete the limiting and fixing of the first unfolding plate 5. Then, the first unfolding plate 5 and the second unfolding plate 10 are unfolded. The unfolded first unfolding plate 5 and the second unfolding plate 10 can be used to place some connectors or toolboxes and other test tools when performing load tests on low-voltage electrical equipment. When not in use, the extended first unfolding plate 5 and the second unfolding plate 10 can be folded to avoid occupying a lot of space. The above is the working principle of this tooling rack with an expandable space structure.
