Description

Technical Field

[0001] This utility model relates to the field of electrical safety testing technology, specifically to an electrical safety testing device. Background Technology

[0002] With the continuous development and application of electrical technology, the types and quantities of electrical products are constantly increasing, and electrical safety issues are receiving increasing attention. To ensure the safety and reliability of electrical products, various countries have formulated corresponding electrical safety standards and regulations. Electrical safety testing equipment, as an important tool for detecting and verifying whether electrical products comply with these standards and regulations, is also facing increasingly higher technical levels and performance requirements.

[0003] In existing technologies, the technical principles of electrical safety testing equipment are mainly based on electrical safety theory, electromagnetic principles, and related testing standards and methods. These devices test and evaluate the electrical safety performance of electrical products by simulating their electrical states under normal use and fault conditions. However, existing electrical safety testing equipment often requires disassembly of the casing for maintenance. If disassembly is inconvenient, maintenance time is significantly extended, leading to economic losses due to production delays, substantial increases in maintenance costs, and a shortened lifespan due to the accumulation of minor faults and damage from improper maintenance. This severely impacts the normal use, maintenance efficiency, and overall effectiveness of the equipment.

[0004] Based on this, an electrical safety testing device is now provided that can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide an electrical safety testing device to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electrical safety testing device includes: a base plate;

[0008] A protective shell is fixedly installed on the top of the base plate. A workbench is fixedly connected to the top of the base plate. A test bracket is fixedly connected to the top of the workbench. A test interface is fixedly connected to the top of the workbench.

[0009] Quick-release mechanism, which is fixedly installed on the inner surface of the protective shell, is used to quickly install and remove the protective shell;

[0010] The clamping mechanism is fixedly installed on the inner surface of the test bracket and is used to clamp electrical components.

[0011] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0012] In one alternative: the quick-release mechanism includes a mounting base, which is fixedly disposed on the inner surface of the protective shell, a locking block is fixedly connected to the mounting surface of the mounting base, and a locking button is slidably connected to the inner surface of the protective shell.

[0013] In one alternative: a locking component is slidably disposed on the inner surface of the locking block for quickly locking the locking block and the protective shell.

[0014] In one alternative embodiment: the locking assembly includes a first wedge block, which is slidably disposed on the inner surface of the locking block. A spring is fixedly connected to the inner surface of the locking block, and the end of the spring is fixedly connected to the right side of the locking block. A plug rod is slidably connected to the inner surface of the worktable.

[0015] In one alternative embodiment: the clamping mechanism includes a limiting plate, which is fixedly disposed on the inner surface of the test bracket. A second wedge block is slidably connected to the top of the limiting plate. A screw is rotatably connected to the left end of the second wedge block. The outer surface of the screw is threadedly connected to the inner surface of the test bracket and the limiting plate. A knob is fixedly connected to the left end of the screw. A rotating bracket is fixedly connected to the top of the limiting plate. A pressure rod is rotatably connected to the inner surface of the rotating bracket. A roller is rotatably connected to the inner surface of the pressure rod.

[0016] In one alternative: a control panel is located on the top of the protective shell, and control buttons are located on the top of the control panel.

[0017] In one alternative: the inner surface of the worktable is provided with a sliding groove that matches the locking block.

[0018] In one alternative: the inner surface of the locking block is provided with a sliding groove that matches the first wedge block, and the inner surface of the worktable is provided with a sliding groove that matches the first wedge block and the insertion rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model aligns the locking block with the sliding groove of the worktable. Due to the pressure ramp design, the first wedge block, after being squeezed by the sliding groove, inserts into the sliding groove of the locking block and compresses the spring. The spring then returns to its original position, thus fixing the first wedge block in the sliding groove of the worktable. To unlock, manually press the locking button. The button pushes the insert rod to move, and the insert rod pushes the first wedge block back into the locking block.

[0021] 2. This utility model involves placing the component to be tested in a test bracket and manually turning a knob to drive the screw to rotate. The screw, threadedly connected to the test bracket and the limiting plate, moves to the right. Simultaneously, the screw, through a rotating connection, drives the second wedge block to the right. The pressing ramp on the second wedge block applies pressure to the roller, which in turn causes the pressure rod to rotate within the rotating bracket. The other end of the pressure rod then presses and fixes the component in place. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figures 1-5 As shown, an electrical safety testing device includes: a base plate 1, a protective shell 2, a quick-release mechanism, and a clamping mechanism; the protective shell 2 is fixedly disposed on the top of the base plate 1, a workbench 3 is fixedly connected to the top of the base plate 1, a test bracket 4 is fixedly connected to the top of the workbench 3, and a test interface 5 is fixedly connected to the top of the workbench 3; the quick-release mechanism is fixedly disposed on the inner surface of the protective shell 2 for quick installation and removal of the protective shell 2; the clamping mechanism is fixedly disposed on the inner surface of the test bracket 4 for clamping electrical components; a control panel 19 is disposed on the top of the protective shell 2, and control buttons 20 are disposed on the top of the control panel 19 for convenient internal electrical control; the test interface 5 facilitates the connection of test leads and facilitates testing after power-on.

[0030] In one embodiment, such as Figure 3 As shown, the quick-release mechanism includes a mounting base 6, which is fixedly disposed on the inner surface of the protective shell 2. A locking block 7 is fixedly connected to the mounting surface of the mounting base 6. A locking button 8 is slidably connected to the inner surface of the protective shell 2. A locking component is slidably disposed on the inner surface of the locking block 7 for quickly locking the locking block 7 and the protective shell 2. A sliding groove adapted to the locking block 7 is provided on the inner surface of the workbench 3 to facilitate the sliding installation of the locking block 7. The mounting base 6 facilitates the installation of the locking block 7. The locking button 8 is designed so that the operator can manually press the locking button 8 to squeeze the insert rod 11.

[0031] In one embodiment, such as Figure 4 As shown, the locking assembly includes a first wedge block 9, which is slidably disposed on the inner surface of the locking block 7. A spring 10 is fixedly connected to the inner surface of the locking block 7, and the end of the spring 10 is fixedly connected to the right side of the locking block 7. A plug rod 11 is slidably connected to the inner surface of the worktable 3. A sliding groove adapted to the first wedge block 9 is formed on the inner surface of the locking block 7, facilitating the sliding of the first wedge block 9 on the inner surface of the locking block 7. A sliding groove adapted to the first wedge block 9 and the plug rod 11 is formed on the inner surface of the worktable 3. This facilitates the locking of the first wedge block 9 and the sliding of the insertion rod 11. When the insertion rod 11 slides, it pushes the first wedge block 9 back into the locking block 7, thereby releasing the lock. The outer surface of the first wedge block 9 is provided with a pressing slope, so that when it contacts the sliding groove opened on the surface of the worktable 3, the first wedge block 9 is subjected to a pressing force and is pushed into the locking block 7, so that the locking block 7 is inserted into the worktable 3. The spring 10 is provided to facilitate the reset of the first wedge block 9 and its insertion into the sliding groove on the inner surface of the worktable 3 for limiting.

[0032] In one embodiment, such as Figure 5As shown, the clamping mechanism includes a limiting plate 12, which is fixedly mounted on the inner surface of the test bracket 4. A second wedge block 13 is slidably connected to the top of the limiting plate 12. A screw 14 is rotatably connected to the left end of the second wedge block 13. The outer surface of the screw 14 is threadedly connected to the inner surfaces of the test bracket 4 and the limiting plate 12. A knob 15 is fixedly connected to the left end of the screw 14. A rotating bracket 16 is fixedly connected to the top of the limiting plate 12. A pressure rod 17 is rotatably connected to the inner surface of the rotating bracket 16. A roller 18 is rotatably connected to the inner surface of the pressure rod 17. The limiting plate 12 facilitates the sliding of the second wedge block 13. The second wedge block 13 has a pressing ramp at its top, which facilitates pressing the roller 18 when sliding to the right, causing the pressure rod 17 to rotate on the inner surface of the rotating bracket 16, thereby pressing the component. The screw 14 is threadedly connected to the test bracket 4 and the limiting plate 12, so that the screw 14 moves to the right when rotating. Since the screw 14 is rotatably connected to the second wedge block 13, the screw 14 drives the second wedge block 13 to move to the right. The knob 15 allows the operator to manually rotate the screw 14. The rotating bracket 16 facilitates the installation of the pressure rod 17.

[0033] The above embodiment discloses an electrical safety testing device. Before the test operation begins, preparations must be made to ensure that the test environment meets the requirements of the product manual and test standards, including conditions such as temperature, humidity, and electromagnetic interference. Then, the test leads of the insulation resistance tester are correctly connected to the test object and test interface 5 for testing. The test results are judged according to the test standards to determine whether they are qualified, and a test report is generated. By aligning the locking block 7 with the sliding groove on the workbench 3, and then installing the protective shell 2, when the first wedge block 9 contacts the sliding groove, the pressure ramp on its surface is subjected to the squeezing force from the sliding groove, causing the first wedge block 9 to insert into the sliding groove on the inner surface of the locking block 7 and compress the spring 10. The spring 10 then drives the first wedge block 9 to reset, limiting its position within the sliding groove on the inner surface of the workbench 3. When unlocking is required, the locking button 8 is manually pressed. The locking button 8 pushes the insertion rod 11 to move, causing the insertion rod 11 to push the first wedge block 9 into the locking block 7, thus completing the process. To unlock, the component to be tested is placed in the test bracket 4, and then the knob 15 is manually turned to rotate the screw 14. Since the screw 14 is threadedly connected to the test bracket 4 and the limiting plate 12, the screw 14 moves to the right when rotating. Since the screw 14 is rotatably connected to the second wedge block 13, the screw 14 drives the second wedge block 13 to move to the right. The extrusion ramp on the surface of the second wedge block 13 extrudes the roller 18, thereby subjecting the pressure rod 17 to extrusion force and causing it to rotate on the inner surface of the rotating bracket 16. At this time, the other end of the pressure rod 17 presses and fixes the component.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
