Description

Technical Field

[0001] This utility model relates to the field of vibration test bench technology, and in particular to a safety protection device for vibration test bench. Background Technology

[0002] Vibration testing machines simulate various environments encountered by products during manufacturing, assembly, transportation, and use to determine whether a product can withstand environmental vibrations. They are applicable to research, development, quality control, and manufacturing in various industries such as electronics, electromechanical, optoelectronics, automobiles, and toys.

[0003] Existing vibration testing machines operate in an open-type environment, lacking both protection and the ability to limit the movement of the tested items. This lack of protection allows the tested items to easily break during vibration, resulting in flying debris that can cause injury. Furthermore, the lack of limiting mechanisms allows the tested items to easily slide across the testing platform during vibration. Therefore, there is an urgent need to develop a vibration testing platform safety device that provides excellent protection against breakage and flying debris during vibration testing, and also limits the movement of the tested items at their edges to prevent them from sliding around on the testing platform. This device would overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a safety protection device for a vibration test bench to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A safety protection device for a vibration test bench includes a vibration test bench, a transparent protective cover, a limiting mechanism, and a rotary drive mechanism. Two transparent protective covers are mounted on the vibration test bench. A rotating shaft is fixed to the bottom of each transparent protective cover and rotatably connected to the side of the vibration test bench. A rotary drive mechanism for rotating the transparent protective cover is installed on both the left and right sides of the vibration test bench. A limiting mechanism is installed inside each transparent protective cover. The limiting mechanism includes a mounting rod, a semi-circular sliding sleeve, a limiting baffle, and a fastening bolt. The mounting rod is fixed inside the transparent protective cover, and a semi-circular sliding sleeve is slidably mounted on the mounting rod. A limiting baffle is fixedly connected to the lower side of the semi-circular sliding sleeve, and a fastening bolt that presses against the mounting rod is mounted on the semi-circular sliding sleeve.

[0007] Preferably, the mounting rod is provided with a limiting groove for the movement of the semi-circular sleeve.

[0008] Preferably, the two transparent protective covers are arranged symmetrically about the central axis of the vibration test bench.

[0009] Preferably, the rotary drive mechanism includes a drive motor, a first gear, and a second gear. The drive motor is fixed to the side of the vibration test bench. The first gear is fixed on the output shaft of the drive motor. A second gear meshing with the first gear is provided on one side of the first gear. The second gear is fixedly installed on the rotating shaft.

[0010] Preferably, a switch button is fixedly installed on the side of the vibration test bench, and the drive motor is electrically connected to the switch button via a wire.

[0011] Preferably, the transparent protective cover is made of transparent acrylic sheet.

[0012] The beneficial effects of this utility model are as follows: When using this vibration test bench safety protection device, the item to be tested is placed in the center of the top surface of the vibration test bench. The position of the limiting baffle is then adjusted according to the size of the item. Loosening the fastening bolts allows movement of the semi-circular sliding sleeve and the limiting baffle. After adjustment, the fastening bolts are tightened. Then, the drive motor rotates the first and second gears, which in turn rotate the shaft. The shaft then rotates the transparent protective cover, allowing it to cover the item to be tested, preventing it from shattering and injuring people during the vibration test. Simultaneously, the limiting baffle restricts the edge of the item, preventing it from sliding around on the vibration test bench. In summary, this utility model provides good protection, preventing the item to be tested from shattering and injuring people during the vibration test, and also restricts the edge of the item to prevent it from sliding around on the vibration test bench.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] See Figures 1-5 In this embodiment of the present invention, a safety protection device for a vibration test bench includes a vibration test bench 1, a transparent protective cover 2, a limiting mechanism 3, and a rotary drive mechanism 4. Two transparent protective covers 2 (the vibration test bench 1 is a prior art product) are installed on the vibration test bench 1. The two transparent protective covers 2 are symmetrically arranged about the central axis of the vibration test bench 1. A rotating shaft 201 is fixed to the bottom of each transparent protective cover 2, and the rotating shaft 201 is rotatably connected to the side of the vibration test bench 1. A rotary drive mechanism 4 for rotating the transparent protective cover 2 is installed on both the left and right sides of the vibration test bench 1. A limiting mechanism 3 is installed inside each transparent protective cover 2. The limiting mechanism 3 includes: a mounting rod 301, a semi-circular sliding sleeve 302, a limiting baffle 303, and a fastening bolt 304. The mounting rod 301 is fixed to the transparent protective cover 2. Inside the protective cover 2, a semi-circular sliding sleeve 302 is slidably mounted on the mounting rod 301. The mounting rod 301 is provided with a limiting groove 3011 for the movement of the semi-circular sliding sleeve 302. A limiting baffle 303 is fixedly connected to the lower side of the semi-circular sliding sleeve 302. A fastening bolt 304 is installed on the semi-circular sliding sleeve 302 that presses against the mounting rod 301. When the fastening bolt 304 is tightened, it presses tightly against the mounting rod 301, thus preventing the semi-circular sliding sleeve 302 from sliding. In use, the item to be tested is placed on the vibration test bench 1. The limiting baffle 303 limits the edge of the item to be tested, preventing the item to be tested from sliding around when vibrating on the vibration test bench 1. In addition, loosening the fastening bolt 304 allows the semi-circular sliding sleeve 302 and the limiting baffle 303 to move, so as to limit the items to be tested of different sizes.

[0023] The rotary drive mechanism 4 includes a drive motor 401, a first gear 402, and a second gear 403. The drive motor 401 is fixed to the side of the vibration test bench 1. The first gear 402 is fixed on the output shaft of the drive motor 401. A second gear 403 meshes with the first gear 402 on one side. The second gear 403 is fixedly mounted on the rotating shaft 201. A switch button 4011 is fixedly mounted on the side of the vibration test bench 1. The drive motor 401 is electrically connected to the switch button 4011 through a wire. In use, the drive motor 401 drives the first gear 402 and the second gear 403 to rotate, the second gear 403 drives the rotating shaft 201 to rotate, and the rotating shaft 201 drives the transparent protective cover 2 to rotate.

[0024] The transparent protective cover 2 is made of transparent acrylic sheet.

[0025] Working principle: When using the safety protection device of this vibration test bench, the item to be tested is placed in the middle of the top surface of the vibration test bench 1. The position of the limiting baffle 303 is then adjusted according to the size of the item to be tested. The fastening bolt 304 is loosened, allowing the semi-circular sliding sleeve 302 and the limiting baffle 303 to move. After adjustment, the fastening bolt 304 is tightened. Then, the drive motor 401 drives the first gear 402 and the second gear 403 to rotate. The second gear 403 drives the rotating shaft 201 to rotate, which in turn drives the transparent protective cover 2 to rotate. This allows the transparent protective cover 2 to cover the item to be tested, preventing it from breaking and flying fragments that could injure people during the vibration test. At the same time, the limiting baffle 303 can limit the edge of the item to be tested, preventing it from sliding around on the vibration test bench 1 during vibration.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
