Description

Technical Field

[0001] The utility model relates to the technical field of product detection, in particular to a waterproof detection device used in the production of trolley cases. Background Art

[0002] A trolley case is a kind of travel equipment that is easy to carry and practical. It usually consists of a trolley and rollers, which makes the trolley case both portable and draggable, greatly reducing the burden of carrying luggage during travel. The emergence of this design has made the trolley case one of the most popular types of luggage. The structure of the trolley case includes a trolley and rollers, where the trolley is divided into single-tube and double-tube, and the roller is also divided into square tube and round tube. In addition, the design of the trolley case is also constantly innovating. For example, a new cylindrical design has emerged. This design allows the trolley case to better adapt to various terrains, and can even be directly dragged up and down stairs, further enhancing the convenience of use. As for the materials of the trolley case, there are many kinds, including cloth boxes, ABS hard boxes, leather boxes, PC, etc. These materials not only give the trolley case a different appearance and touch, but also determine the performance characteristics of the trolley case, such as durability, weight and price. For example, ABS suitcases are hard and impact-resistant, while PC suitcases are lighter and more durable. With the development of technology, suitcases are becoming more and more diverse. For example, according to the direction of the wheels, they can be divided into directional wheels, universal wheels, and detachable universal wheels. Each design has its specific use environment and advantages. In general, a suitcase is a travel necessity that combines practicality and comfort. Whether it is a short trip or a long journey, it can provide great convenience. Suitcases will encounter rain and snow in daily use scenarios, so the waterproof performance of suitcases is also one of the important indicators of product performance testing during production.

[0003] The utility model with application number 202321239710.0 discloses a waterproof testing device, which drives the threaded rod to rotate by holding two handles, so that the clamping block and the sliding block move down until the two clamping blocks clamp the two ends of the instrument respectively, to ensure the stability of the instrument during the subsequent waterproof test, and drives the water wheel to rotate through the output shaft of the motor, and the water in the frame is stirred by the rotation of the water wheel, which has a good waterproof detection effect on the instrument. The water in the frame can be injected into the water spray pipe through the first connecting pipe and the second connecting pipe through the high-pressure water pump, and finally the water is discharged through multiple nozzles to spray the instrument for waterproof testing;

[0004] However, the above-mentioned waterproof testing device only performs a waterproof test on the test piece by spraying water from above the water spray pipe, which cannot simulate rain from all directions on rainy days, making the test result incomplete. When the above-mentioned waterproof testing device performs the test, the test piece is fixed between the U-shaped plates and cannot be rotated to detect the waterproof performance in all directions, which can easily affect the test result. Therefore, the utility model proposes a waterproof testing device for suitcase production to solve the problems existing in the prior art. Utility Model Content

When it is necessary to simulate the waterproof performance of the trolley case in various directions on rainy days, the first motor 6 drives the gear 7 to rotate and mesh with the arc-shaped rack 4 to drive the slider 3 and the spray rack 8 to slide along the arc-shaped guide rail 2, thereby realizing the simulation of rainwater in various reverse directions, improving the detection effect, and realizing the detection of the waterproof performance of the trolley case in various directions.

[0021] The circulating water supply mechanism includes a water tank 9, a water pump 10, a water supply hose 11 and a circulating water pipe 12. A water tank 9 is provided at the bottom of the detection box 1. A water pump 10 is connected to one side of the water tank 9. A water supply hose 11 is connected between the water pump 10 and the spray rack 8. A circulating water pipe 12 is provided on the other side of the bottom of the detection box 1 and is connected to the water tank 9. When water is supplied, the water pump 10 is started to pump the water in the water tank 9 to the spray rack 8 through the water supply hose 11 for spraying. After spraying, the water flow flows back into the water tank 9 through the circulating water pipe 12, thereby reducing the waste of water resources while performing spray detection.

[0022] The positioning and rotating mechanism includes a turntable 13, a second motor 14, a waterproof sleeve 15, a connecting shaft 16, a roller 17 and a limiting mechanism. A turntable 13 is rotatably provided in the middle of the bottom of the detection box 1, a second motor 14 is fixedly provided in the middle of the bottom of the detection box 1, a waterproof sleeve 15 is fixedly provided in the middle of the bottom of the detection box 1, a connecting shaft 16 is rotatably provided in the waterproof sleeve 15, and rollers 17 are symmetrically rotated at the bottom of the turntable 13. A limiting mechanism is provided on the turntable 13, and the connecting shaft 16 is fixedly connected to the turntable 13 and the output end of the second motor 14 respectively up and down. There are four groups of rollers 17. When the spray test is performed, the second motor 14 starts to drive the connecting shaft 16 to drive the turntable 13 to rotate, and the waterproof sleeve 15 prevents water from seeping through the gap. When the turntable 13 rotates, the roller 17 rotates in contact with the bottom of the detection box 1 to keep the turntable 13 stable, and drives the trolley case placed on the turntable 13 to rotate, so as to detect the waterproof performance of the trolley case in all directions.

[0023] The limiting mechanism includes a fixing plate 18, a spring 19 and a limiting plate 20. The fixing plate 18 is symmetrically fixed on the turntable 13, and a spring 19 is fixed on the inner side of the fixing plate 18. A limiting plate 20 is fixed on the inner side of the spring 19.

[0024] A timer 21 is fixedly provided on the other side of the detection box 1, and a prompt light 22 is fixedly provided above the timer 21. The timer 21 is electrically connected to the prompt light 22. When it is necessary to accurately control the variable of the spraying time, the timer 21 is turned on to set the time while starting the waterproof test. After the time returns to zero, the prompt light 22 lights up to prompt the staff to stop the test, so that the test time for each suitcase is the same, which is convenient for horizontal comparison of the waterproof performance of each suitcase.

[0025] When the waterproof detection device for suitcase production is used for detection, the suitcase is placed on the turntable, and the spring force is used to make the limit plate close to the suitcase for limit to prevent the suitcase from displacement when the turntable rotates. When the detection is performed, the water pump is started to pump the water in the water tank to the spray rack through the water supply hose and then spray it to spray the suitcase to simulate rainy weather to detect the waterproof effect of the suitcase. When it is necessary to perform waterproof detection on all directions of the suitcase, the first motor is started to drive the gear to rotate and mesh with the arc-shaped rack to drive the spray rack and the slider to slide and adjust along the arc-shaped guide rail, so that the spray rack can move and adjust the spray angle to simulate rain in all directions on rainy days. At the same time, the second motor is started to drive the connecting shaft and the turntable to rotate so that the suitcase rotates slowly in the detection box to realize waterproof detection in all directions. When the spray detection starts, the spray detection time is set on the timer as needed. After the timer time returns to zero, the prompt light is turned on to prompt the staff to stop the detection. The sprayed water flows back into the water tank through the circulating water pipe for continuous recycling.
