Description

Technical Field

[0001] The utility model relates to the technical field of test benches, in particular to an electrical engineering and automation test bench with a dustproof structure. Background Art

[0002] An electrical test bench is a specialized equipment platform used for conducting various tests on electrical equipment and systems. It simulates the various operating conditions of electrical equipment in actual operation and, through a series of testing methods, inspects, verifies, and evaluates the performance, parameters, and functions of electrical equipment to ensure its quality, safety, and reliability.

[0003] When using existing test benches, in order to prevent dust from affecting the test, they are usually used with a dust cover. The dust cover is provided with an operating port, and the operating port is equipped with an opening and closing device to seal the dust cover. However, the existing opening and closing methods usually adopt push-pull and flip-up types. When the opening and closing device is opened, the cover is prone to automatically move or flip over, affecting the normal operation of the staff. When taking and placing the test equipment, the cover is prone to flip over due to its own movement, causing bumps and damage to the equipment being taken and placed, resulting in poor results during actual use. Utility Model Content

[0004] In response to the above problems, the purpose of the present utility model is to provide an electrical engineering and automation test bench with a dustproof structure to solve the problem that the sealing plate is prone to move or flip over when opened, which is inconvenient for staff to operate, and the moving or flipping sealing plate is prone to cause bumps and damage to the experimental equipment being taken and placed.

[0006] The beneficial effects of the utility model are as follows: through the upward movement of the sealing plate, the fixed block on the sealing plate squeezes the beveled surface on the locking block, so that the locking block moves to one side with the moving rod and the telescopic column, and the telescopic column squeezes the spring, thereby moving the locking block into the avoidance groove, making it convenient for the fixed block to dock with the stabilizing rod, and with the rebound of the spring, the locking block is stuck in the locking groove, locking the fixed block and the sealing plate, thereby ensuring that the sealing plate remains sufficiently stable when opened and will not fall automatically, thereby improving stability.

[0007] In order to limit and guide the sealing plate;

[0008] As a further improvement of the above technical solution: both sides of the sealing plate are slidably connected to fixed rods, the fixed rods are fixedly connected to the transparent dust cover, and a sliding groove is provided on the side of the fixed rod in contact with the sealing plate, and a slider is slidably connected in the sliding groove;

[0009] The beneficial effect of this improvement is that the sealing plate can be guided by using the slide groove and the slider to ensure that the sealing plate is sufficiently stable during the lifting process and will not tilt or shake, so that the sealing plate always maintains a vertical up and down movement trajectory.

[0010] In order to achieve sealing of the connection between the sealing plate and the laboratory bench body;

[0011] As a further improvement of the above technical solution: a sealing groove is provided on the upper end surface of the test bench body, the sealing groove is located directly below the sealing plate, a sealing strip is fixedly connected to the lower end surface of the sealing plate, and the sealing strip is adapted to the sealing groove;

[0012] The beneficial effect of this improvement is that the connection between the sealing plate and the test bench body can be sealed by using the sealing groove and the sealing strip, thereby preventing dust from entering the transparent dust cover through the analysis.

[0013] In order to achieve effective ventilation inside the transparent dust cover;

[0014] As a further improvement of the above technical solution: an air inlet is provided on the other side of the transparent dust cover, and an air outlet is provided on the side of the transparent dust cover away from the air inlet;

[0015] The beneficial effect of this improvement is that through the use of the air inlet and outlet, the air circulation of the transparent dust cover can be guaranteed, and the heat emitted by the equipment inside the transparent dust cover cannot be effectively discharged, which affects the normal operation of the equipment.

[0016] In order to filter the dust in the air;

[0017] As a further improvement of the above technical solution: an air particle filter is provided at both the air inlet and the air outlet, and the air particle filter is fixedly connected to the transparent dust cover;

[0018] The beneficial effect of this improvement is that an air particle filter can be installed through the ventilation port, which can effectively filter dust particles in the air, achieving the dual effect of ventilation and dust prevention, and preventing dust from accumulating on the test equipment and affecting the accuracy of the test data.

[0019] In order to achieve heat dissipation inside the transparent dust cover;

[0020] As a further improvement of the above technical solution: a heat dissipation fan is provided at the air outlet, and the heat dissipation fan is fixedly connected to one of the air particulate filters;

[0021] The beneficial effect of this improvement is that the use of the cooling fan can ensure the circulation of air inside the test bench, avoiding the accumulation of heat generated in the closed environment that affects the normal operation of the electrical equipment.

[0022] In order to support the test bench body;

[0023] As a further improvement of the above technical solution: support columns are fixedly connected to the four corners of the lower end surface of the test bench body;

[0024] The beneficial effect of this improvement is that the test bench body can be supported by using the support column, ensuring that the test bench body is sufficiently stable during private use and will not tilt or shake.
