Description

Technical Field

[0001] This utility model relates to the technical field of waterproof testing machines, and in particular to an open-type multi-level waterproof testing machine. Background Technology

[0002] Currently, in industries such as electronics, electrical appliances, and waterproofing materials, testing the waterproofing performance of products is a crucial step in ensuring product quality and reliability. To meet the diverse waterproofing requirements faced by different products in practical applications, waterproofing testing machines are widely used in production and testing processes, especially in dynamic waterproofing tests such as water spraying and water sprinkling. The uniformity and control precision of the spraying process of the testing equipment have become one of the core indicators for evaluating equipment performance.

[0003] In existing technologies, most waterproof testing machines employ fixed-structure spray devices, with a motor driving a rotating shaft or nozzle to change the spray direction. Some machines also incorporate guide rail structures, along with sliders and transmission rods, to reciprocate the spray arm or nozzle, adjusting the spray path through mechanical transmission. This allows for multi-angle, multi-intensity water spray tests on the test object's surface. These structures typically complete the test using a single spray system, resulting in a relatively fixed structure with limited adaptability and linkage, and often relying on repeated spraying actions to simulate environments with different protection levels.

[0004] However, existing waterproof testing machines have shortcomings in achieving multi-directional synchronous spraying. Specifically, traditional structures struggle to efficiently link multiple spray components to achieve synchronous movement through a single drive mechanism. Especially when conducting large-area or multi-angle spraying tests, multiple independent drive devices are often required, resulting in complex structures, high control difficulty, and poor equipment operational stability. This makes it difficult to meet the demands for efficient, multi-level dynamic waterproof testing. Therefore, an open-type multi-level waterproof testing machine is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an open-type multi-level waterproof testing machine, which aims to improve the problem that traditional structures in the prior art are difficult to achieve synchronous movement of multiple spray components through a single drive mechanism.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an open-type multi-level waterproof testing machine, comprising a testing machine body, wherein symmetrical arc-shaped spray pipes are installed inside the testing machine body, a bracket is installed on one side of the testing machine body, and an adjustment component is installed on the lower surface of the bracket;

[0007] The adjustment assembly includes a first connecting rod, a second connecting rod, two hinge blocks, a first sliding plate, and a second sliding plate. The lower surfaces of the two hinge blocks are fixedly connected to the upper surface of the bracket. One side of the first sliding plate is rotatably connected to the outer wall of one of the hinge blocks, and one side of the second sliding plate is rotatably connected to the outer wall of the other hinge block. One side of the outer wall of the first connecting rod is rotatably connected to the outer wall of the first sliding plate, and one side of the outer wall of the second connecting rod is rotatably connected to the outer wall of the second sliding plate. A first motor is fixedly connected to the lower surface of the bracket. An eccentric wheel is fixedly connected to the output end of the first motor. A first rotating plate is rotatably connected to one side of the outer wall of the eccentric wheel. A V-shaped plate is rotatably connected to one side of the outer wall of the first rotating plate, and a first hinge seat is rotatably connected to one side of the V-shaped plate.

[0008] Furthermore, both the first and second slide plates are slidably connected with connecting rods, and one end of each connecting rod is fixedly connected to the outer wall of the arc-shaped spray pipe.

[0009] Furthermore, a support base is fixedly connected directly below the two arc-shaped spray pipes, and a second motor is fixedly connected inside the support base. A rotating seat is fixedly connected to the output end of the second motor.

[0010] Furthermore, a bidirectional lead screw is rotatably connected inside the rotating seat, and symmetrical clamping plates are threaded onto the outer wall of the bidirectional lead screw.

[0011] Furthermore, a support is fixedly connected to one side of the outer wall of the clamping plate, and a rotating plate is slidably connected inside the support.

[0012] Furthermore, a hinge seat two is fixedly connected to the side near the support, and a rotating shaft is rotatably connected inside the hinge seat two.

[0013] Furthermore, an adjusting screw is rotatably connected inside the rotating shaft, a rotating sleeve is rotatably connected inside the second rotating plate, the adjusting screw is threadedly connected to the rotating sleeve, and a clamping block is rotatably connected inside the second rotating plate.

[0014] Furthermore, the upper surface of the hinge seat is fixedly connected to the top of the inner wall of the bracket, one side of the V-shaped plate is rotatably connected to one side of the outer wall of the connecting rod, and the other side of the V-shaped plate is rotatably connected to one side of the outer wall of the connecting rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, a motor drives a rotating plate on one side of an eccentric wheel to reciprocate. The rotating plate then drives a V-shaped plate to rotate on one side of a hinge seat. The rotation of the V-shaped plate facilitates the efficient rotation of connecting rods one and two. The cooperation of connecting rods one and two facilitates the rotation of sliding plate two and connecting rods. Simultaneously, the cooperation of sliding plate two and connecting rods enables two arc-shaped spray pipes to spray the items simultaneously, achieving an efficient waterproof test and improving the machine's practicality.

[0017] 2. In this utility model, by placing the required testing machine above the rotating seat, the clamping plate clamps and fixes the testing machine by rotating the bidirectional lead screw, and then by rotating the adjusting lead screw, the rotating sleeve drives the rotating plate two to slide inside the support, thereby achieving the effect of driving the clamping block to further clamp the testing machine. Then, the rotating seat is driven to rotate by the second motor, thereby achieving the effect of the testing machine being tested and being stably placed on the rotating seat, thus improving the practicality of the machine.

[0025] 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.

[0026] Reference Figures 1-5This utility model provides an embodiment of an open-type multi-level waterproof testing machine, comprising a machine body 1, which is used to construct an overall waterproof testing platform. Symmetrical arc-shaped spray pipes 2 are installed inside the machine body 1. The arc-shaped spray pipes 2 can provide multi-angle spray coverage, enabling spray testing of the object under test from different angles. A bracket 3 is installed on one side of the machine body 1, which serves to install and support the adjustment components. An adjustment component is installed on the lower surface of the bracket 3. The adjustment component drives the spray pipes to swing through a power transmission mechanism to achieve the waterproof level adjustment function. The adjustment component includes a connecting rod 9. Linkage 10, two hinge blocks 11, slide plate 12, and slide plate 2 13; link 1 and link 2 form a synchronous linkage structure, transmitting rotational power to the slide plate. The lower surfaces of the two hinge blocks 11 are fixedly connected to the upper surface of the bracket 3 to fix the hinge fulcrum of the slide plate and ensure the stability of the sliding structure. One side of slide plate 12 is rotatably connected to one side of the outer wall of a hinge block 11, realizing the rotatability of slide plate 12, which helps to drive the spray pipe to swing. One side of slide plate 2 13 is rotatably connected to one side of the outer wall of another hinge block 11, cooperating with slide plate 12 to achieve dual-sided coordinated drive; link 1 One side of the outer wall of the 9th rod is rotatably connected to one side of the outer wall of the slide plate 12, and one side of the outer wall of the second connecting rod 10 is rotatably connected to one side of the outer wall of the second slide plate 13. This connection method can effectively transmit power, enabling the slide plate to perform angle adjustment movement. A motor 4 is fixedly connected to the lower surface of the bracket 3. The motor 4 provides reciprocating drive power for the adjustment component. An eccentric wheel 5 is fixedly connected to the output end of the motor 4. The eccentric wheel 5 can convert the rotational motion of the motor into reciprocating eccentric motion. A rotating plate 6 is rotatably connected to one side of the outer wall of the eccentric wheel 5. The rotating plate 6 reciprocates with the eccentric wheel 5, driving the operation of the subsequent structure. A V-shaped connecting rod is rotatably connected to one side of the outer wall of the rotating plate 6. The V-shaped plate 8 converts the reciprocating motion of the rotating plate 6 into angular changes, which are then transmitted to the linkage system. A hinge seat 7 is rotatably connected to one side of the V-shaped plate 8, which provides a fixed rotation point for the V-shaped plate 8 to ensure the stability of the motion path. Connecting rods 14 are slidably connected inside the slide plate 12 and slide plate 13. The sliding of the connecting rods 14 inside the slide plate can drive the spray pipe to swing up and down, realizing dynamic changes in the spray angle. One end of each connecting rod 14 is fixedly connected to the outer wall of the arc-shaped spray pipe 2. The connecting rods 14 convert the mechanism motion into synchronous spraying action of the arc-shaped spray pipe 2, improving the test efficiency.

[0027] Specifically, motor 4 drives the eccentric wheel 5 to rotate plate 6 on one side in reciprocating motion. Then, rotating plate 6 drives V-shaped plate 8 to rotate on the hinge seat 7. The rotation of V-shaped plate 8 facilitates the efficient rotation of connecting rod 9 and connecting rod 10. The cooperation of connecting rod 9 and connecting rod 10 facilitates the rotation of sliding plate 13 and connecting rod 14. At the same time, the cooperation of sliding plate 13 and connecting rod 14 enables the two arc-shaped spray pipes 2 to spray the items simultaneously, achieving an efficient waterproof test and improving the machine's practicality.

[0028] Reference Figures 1-5A support base 15 is fixedly connected directly below the two arc-shaped spray pipes 2. The support base 15 supports the lower mechanism of the arc-shaped spray pipes 2, providing an installation foundation and stable support. A second motor 16 is fixedly connected inside the support base 15. The second motor 16 serves as an independent drive source, used to drive the clamping or adjustment operation of the spray pipe clamping structure. A rotating seat 17 is fixedly connected to the output end of the second motor 16. The rotating seat 17 serves as a transmission connector, used to transmit the rotational output of the motor to the bidirectional lead screw 18. The bidirectional lead screw 18 is rotatably connected inside the rotating seat 17. The bidirectional lead screw 18 is a linear drive component with a double-threaded structure, which can synchronously drive the clamping plates 1 on both sides. 9. Linear movement is achieved. The outer wall of the bidirectional lead screw 18 is threaded with symmetrical clamping plates 19. The clamping plates 19 are used to clamp test objects of different sizes or structures, ensuring their stability and uniform force distribution during the test. A support 20 is fixedly connected to one side of the outer wall of the clamping plate 19. The support 20 provides longitudinal sliding guidance support for the clamping structure, ensuring smooth movement of the clamping plate 19. A rotating plate 21 is slidably connected inside the support 20. The rotating plate 21 performs sliding adjustment and fine-tuning of the rotation angle within the support 20 to match changes in the shape of the test object. A hinge seat 22 is fixedly connected to the side near the support 20, providing... The rotation fulcrum of the rotating shaft 23 ensures stable and controlled rotation. The rotating shaft 23 is rotatably connected inside the hinge seat 22. As the core transmission element, the rotating shaft 23 transmits driving force to the adjusting screw 24. The adjusting screw 24 is rotatably connected inside the rotating shaft 23, used to precisely adjust the position of the clamping block 26 to accommodate clamping requirements of different shaped objects. A rotating sleeve 25 is rotatably connected inside the rotating plate 21. After the rotating sleeve 25 is threadedly connected to the adjusting screw 24, the clamping block 26 in the rotating plate 21 can be adjusted forward and backward by rotating the adjusting screw 24. The adjusting screw 24 is threadedly connected to the rotating sleeve 25. The screw drive function improves adjustment accuracy and structural response sensitivity. The rotating plate 21 has a rotatable clamping block 26 inside, which directly acts on the surface of the object being measured and is used to cooperate with the clamping plate 19 to achieve a fastening function. The upper surface of the hinge seat 7 is fixedly connected to the top of the inner wall of the bracket 3. This installation method ensures the stable positioning of the entire eccentric drive structure in the vertical direction and improves the reliability of the system operation. One side of the V-shaped plate 8 is rotatably connected to one side of the outer wall of the connecting rod 9, and the other side of the V-shaped plate 8 is rotatably connected to one side of the outer wall of the connecting rod 10. This structure converts the eccentric drive into the synchronous rotation of the connecting rods on both sides through the V-shaped plate 8, thereby driving the overall operation of the spray system.

[0029] Specifically, through the above-mentioned structural configuration, motor 2 16 drives bidirectional lead screw 18 to rotate via rotating seat 17, achieving synchronous movement of the left and right symmetrical clamping plates 19. The clamping plates 19 drive the support 20 and its internally slidably connected rotating plate 21 to perform lateral displacement. Furthermore, through the cooperation of hinge seat 22 with rotating shaft 23, adjusting lead screw 24 and rotating sleeve 25, the clamping block 26 is driven to move precisely, thereby achieving effective clamping or releasing of the object under test. This structure, in conjunction with the spray pipe rotation device above, ensures that the object under test is stably positioned in a suitable location during multi-level waterproof spray testing, avoiding deviation, improving spray accuracy and the reliability of test results, and further enhancing the adaptability and ease of operation of the testing machine.

[0030] Working principle: When using this machine for waterproof testing, first place the machine to be tested above the rotating base 17. Then, rotate the double-acting screw 18, which drives the clamping plate 19 to clamp the outside of the testing machine for initial fixation. Next, rotate the adjusting screw 24 to make the rotating sleeve 25 drive the rotating plate 21 to slide inside the support 20. The movement of the rotating plate 21 then causes the clamping block 26 to abut against the outside of the testing machine for secondary fixation. Then, start the testing machine body 1, which sprays water evenly onto the testing machine through the arc-shaped spray pipe 2 to achieve the waterproof test effect. Finally, start the electric motor... Machine 2 16 causes the rotating seat 17 to rotate, thereby achieving the effect of multi-angle adjustment of rotation. At the same time, the starting motor 1 4 drives the rotating plate 1 6 on the outside of the eccentric wheel 5 to rotate. Then, the rotating plate 1 6 drives the V-shaped plate 8 to rotate under the restriction of the hinge seat 1 7. The rotation of the V-shaped plate 8 can drive the connecting rod 1 9 and the connecting rod 2 10 to rotate simultaneously. Then, the connecting rod 1 9 pulls the sliding plate 1 12 to rotate on one side of the hinge block 11, and the connecting rod 2 10 pulls the sliding plate 2 1 3 to rotate on the other side of the hinge block 11. This achieves the effect of driving the connecting rod 14 on one side of the arc-shaped spray pipe 2 to rotate evenly, thereby achieving the effect of efficient waterproof testing of the test machine.

Although the present utility model 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.
