Description

Technical Field

[0001] This utility model relates to the field of electrostatic testing technology, specifically a portable electrostatic testing stand. Background Technology

[0002] Electrostatic discharge (ESD) testing is the process of assessing and measuring the amount of static charge on the surface of an object or material. Static electricity can have a negative impact on product quality, safety, and equipment performance, making ESD testing very important. Tests typically use test fixtures to simulate electrostatic discharge events that may occur in the real world and to evaluate the equipment's immunity and reliability under ESD interference.

[0003] Currently, electrostatic discharge testing fixtures still have some shortcomings, such as the difficulty in controlling the discharge position, which affects testing efficiency.

[0004] To overcome the problem of difficulty in controlling the discharge position and affecting testing efficiency, a prior art Chinese patent (publication number: CN209264858U) discloses an electrostatic testing fixture in which the electrostatic gun is always mounted above the material platform via a lifting frame, eliminating the need to hold the electrostatic gun by hand. The entire testing process is extremely convenient, requiring only the adjustment of the test position via the lifting frame and adjustment seat, effectively improving testing efficiency. At the same time, it prevents fatigue during manual discharge testing, which can lead to inaccurate test results, thereby improving the test effect.

[0005] However, the electrostatic test racks currently in use still have certain shortcomings. The test racks mentioned above improve testing efficiency by adjusting the test position, but the test racks are usually quite large, which is inconvenient to transport or carry, takes up a lot of space, and increases the instability of the rack, making it easy to be damaged during transport. They are also quite troublesome to use. Therefore, it is necessary to improve the existing structure. Utility Model Content

[0006] The purpose of this utility model is to provide a portable electrostatic test rack to solve the problems mentioned in the background art, such as the inconvenience of carrying the electrostatic test rack and the inconvenience of extending the support frame, which affects the efficiency of rack operation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable electrostatic testing rack, comprising a base, a support frame rotatably connected to the top of the base, and a testing platform connected to the side of the support frame.

[0008] The top of the support frame is connected to a connecting frame, the test bench rotates on the side of the connecting frame, and a rotating mechanism is connected between the connecting frame and the test bench, and between the support frame and the base. The rotating mechanism includes a first rotating rod, which is symmetrically rotatably connected to the upper surface of the base.

[0009] An extension block is fixed to the bottom of the connecting frame, and an extension mechanism for adjusting the height of the support frame is provided inside the extension block.

[0010] Furthermore, the rotating mechanism also includes a sliding groove, which is formed on the side of the first rotating rod. Two positioning grooves are formed through the side of the sliding groove, and a second rotating rod slides through the sliding groove. A telescopic groove is formed on the side of the second rotating rod.

[0011] Furthermore, a positioning block slides through the inside of the telescopic groove, and a spring connects the positioning block to the telescopic groove, thus the positioning block and the positioning groove are positioned together.

[0012] Furthermore, the upper surface of the base is also provided with a compression mechanism to improve the carrying stability of the test frame. The compression mechanism includes a threaded rod, which is fixed to the upper surface of the base. A threaded ring is threadedly connected to the surface of the threaded rod, and a through groove is provided on the side of the support frame.

[0013] Furthermore, the extension mechanism includes a movable groove, which is formed on the side of the extension block. A toothed plate is fixed inside the movable groove. The extension block slides inside a guide groove, which is formed on the top of the support frame.

[0014] Furthermore, a rotating groove is provided through the side of the guide groove, and a ratchet is rotatably connected inside the rotating groove. A gear is fixed to the side of the ratchet, and the gear is located inside the movable groove.

[0015] Furthermore, the gear and the toothed plate are meshingly connected, and a rotating block is rotatably connected to the side of the rotating groove near the ratchet. A push rod is fixed to the side of the rotating block, and a torsion spring is connected between the threaded rod and the rotating groove. The push rod slides through the rotating groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This portable electrostatic test rack can reduce the size of the electrostatic test rack by folding and rotating the test platform and support frame, thereby improving the portability of the test rack. The compression of the through groove by the threaded ring can prevent the test rack from shaking and becoming unstable during carrying, thus improving the stability of the test rack. Finally, the support frame can be extended by pushing the connecting frame upward, which improves the ease of operation of the test rack.

[0018] 2. It is equipped with a connecting frame, which allows the test frame to be folded on both sides, reducing its size and improving portability;

[0019] 3. A positioning block is provided. The extension and retraction of the positioning block and the spring can improve the operating efficiency of the first and second rotating rods. Furthermore, since the positioning block has an inclined surface, it can be operated directly by pulling when the second rotating rod extends, resulting in high operating efficiency.

[0020] 4. It is equipped with a threaded ring, which can compress the inner wall of the through groove, thereby improving the stability of the test frame after folding and reducing the noise generated by component collision;

[0021] 5. Equipped with a ratchet, the connecting frame can be locked by positioning the ratchet and the rotating block, which improves the convenience of extending the connecting frame. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Example 1, such as Figures 1-4 The present invention provides the following technical solution to address the problem of the inconvenience of carrying the electrostatic test rack: A rotating mechanism 202 is disclosed, comprising a base 1, a support frame 2 rotatably connected to the top of the base 1, and a test platform 3 connected to the side of the support frame 2; a connecting frame 201 is connected to the top of the support frame 2, and the test platform 3 rotates on the side of the connecting frame 201; rotating mechanisms 202 are connected between the connecting frame 201 and the test platform 3, and between the support frame 2 and the base 1; the rotating mechanism 202 includes a first rotating rod 203 internally, which is symmetrically rotatably connected to the upper surface of the base 1; the connecting frame... An extension block 212 is fixed at the bottom of 201. An extension mechanism for adjusting the height of the support frame 2 is provided inside the extension block 212. The rotating mechanism 202 also includes a sliding groove 204. The sliding groove 204 is opened on the side of the first rotating rod 203. Two positioning grooves 205 are opened through the side of the sliding groove 204. A second rotating rod 206 slides through the sliding groove 204. A telescopic groove 207 is opened on the side of the second rotating rod 206. A positioning block 208 slides through the telescopic groove 207. A spring is connected between the positioning block 208 and the telescopic groove 207. The positioning block 208 and the positioning groove 205 are positioned together.

[0033] When using the test fixture, the test object needs to be placed on the surface of the test platform 3, and then the electrostatic gun is used to test the test object. When the test fixture is not in use, the rotating mechanism 202 between the connecting frame 201 and the test platform 3 needs to be operated first. Pressing the positioning block 208 allows it to slide through the positioning groove 205 and the telescopic groove 207. When the positioning block 208 slides, it can compress the spring inside the telescopic groove 207. After the positioning block 208 is compressed into the telescopic groove 207, the test platform 3 is rotated. When the test platform 3 rotates, it can rotate through the connecting frame 201. When the test platform 3 rotates, it can drive the second rotating rod 206 to move. When the second rotating rod 206 moves, it can slide through the sliding groove 204. When the second rotating rod 206 slides, it can drive the positioning block 205 to move through the sliding groove 204. 8. The second rotating rod 206 and the first rotating rod 203 can be rotated through the test platform 3 and the connecting frame 201 respectively. When the test platform 3 is rotated to the side of the connecting frame 201 and the test platform 3 is close to the connecting frame 201, the second rotating rod 206 can drive the positioning block 208 to move to the side of another positioning groove 205. At this time, the positioning block 208 can be reset by the elastic force of the spring. When the positioning block 208 is reset, it can be positioned through the positioning groove 205. The positioning block 208 can then drive the second rotating rod 206 to be positioned. Then, the connecting frame 201 between the support frame 2 and the test platform 3 is operated. During operation, the support frame 2 is rotated to the upper surface of the base 1, realizing the folding effect of the test frame, thereby improving the portability of the test frame.

[0034] Example 2, as follows Figure 2 , Figure 5 and Figure 6 The present invention provides the following technical solution to address the problem of low stability and collision noise of the test frame: A compression mechanism is disclosed: the upper surface of the base 1 is also provided with a compression mechanism to improve the stability of the test frame. The compression mechanism includes a threaded rod 209, which is fixed to the upper surface of the base 1. A threaded ring 210 is threadedly connected to the surface of the threaded rod 209. A through slot 211 is provided through the side of the support frame 2. When the test frame is folded, the support frame 2 rotates to the side of the base 1. The rotation of the support frame 2 can drive the through slot 211 to rotate, and the support frame 2 is tightly attached to the base 1. When the support frame 2 reaches the surface of the base 1, it can drive the through groove 211 to pass through the side of the threaded rod 209. At this time, the movable threaded ring 210 is inserted from the back of the support frame 2 to the end of the threaded rod 209 and rotates. When the threaded ring 210 rotates, it can slide through the threaded rod 209. When the threaded ring 210 slides to the inner wall of the through groove 211, it can be squeezed. After the through groove 211 is squeezed, it can drive the support frame 2 to be squeezed and fixed to the base 1. When the support frame 2 is squeezed to the base 1, it can prevent the test frame from shaking and becoming unstable during the carrying process, thus improving the stability of the test frame.

[0035] Example 3, as follows Figure 7and Figure 8 The present invention provides the following technical solution to address the problem that the electrostatic test rack is inconvenient to extend the support frame 2, which affects the efficiency of rack operation. An extension mechanism is disclosed: the extension mechanism includes a movable groove 213, which is located on the side of the extension block 212. A toothed plate 214 is fixed inside the movable groove 213. The extension block 212 slides inside the guide groove 215, which is located on the top of the support frame 2. A rotating groove 216 is provided through the side of the guide groove 215. A ratchet 217 is rotatably connected inside the rotating groove 216. A gear 218 is fixed to the side of the ratchet 217. The gear 218 is located inside the movable groove 213 and meshes with the toothed plate 214. A rotating block 219 is rotatably connected to the side of the rotating groove 216 near the ratchet 217. A push rod 220 is fixed to the side of the rotating block 219, and a torsion spring is connected between the threaded rod 209 and the rotating groove 216. The push rod 220 slides through the rotating groove 216.

[0036] When the test fixture is in use, pushing the connecting frame 201 can move the extension block 212. The extension block 212 slides through the guide groove 215 during movement. This sliding motion of the extension block 212 moves the toothed plate 214, which in turn drives the gear 218 to mesh and rotate. The meshing rotation of the gear 218 drives the ratchet 217 to rotate. The ratchet 217's tilting teeth can press against the rotating block 219. After being pressed, the rotating block 219 rotates through the rotating groove 216. This rotation of the rotating block 219 tightens the torsion spring. After 219 is twisted to a certain position, ratchet 217 can rotate through rotating groove 216, and gear 218 can rotate through movable groove 213. At this time, connecting frame 201 can extend support frame 2. When connecting frame 201 extends to the designated position, rotating block 219 can be reset by torsion spring. When rotating block 219 is reset, it can be positioned by locking on the side of flat tooth of ratchet 217. When ratchet 217 is positioned, it can be positioned by gear 218 driving tooth plate 214. When tooth plate 214 is positioned, it can be positioned by connecting frame 201, which improves the practicality and convenience of test frame.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
