Description

Technical Field

[0001] The invention belongs to the field of outdoor product testing equipment, in particular to a rainproof performance testing device for an outdoor backpack. Background Art

[0002] An outdoor backpack is a type of backpack designed specifically for outdoor activities. It combines practicality, durability and comfort to meet the needs of a variety of sports or leisure activities such as outdoor adventures, hiking, mountaineering, camping, cycling, rock climbing, etc. During the production process, outdoor backpacks need to be tested for rainproof performance. Through rainproof performance testing, it can be ensured that the backpack will not be damaged by rainwater penetration when used on rainy days, thereby extending the service life of the backpack.

[0003] The patent with announcement number CN208765900U discloses a rainproof performance testing device for outdoor backpacks, which relates to the field of outdoor product testing equipment, including a bottom plate, a box body is fixedly connected to the top of the bottom plate, a movable box is fixedly connected to the top of the box body, a rotating shaft is rotatably connected between the two sides of the inner wall of the movable box through a bearing, the outer surface of the rotating shaft is fixedly connected to the first pulley and the rotating wheel from left to right, a first motor is fixedly connected to one side of the top of the movable box, and the outer surface of the output shaft of the first motor is fixedly connected to the second pulley. This patent can spray water on the backpack comprehensively through the movement of the nozzle to ensure a more comprehensive detection of the rainproof performance of the backpack, greatly improving the practicality of the detection equipment, so that the backpack can be fully exposed to the rain, and has a good water circulation function, avoiding the waste of water when the backpack is detected, and saving water resources.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] Since the backpack has a certain elasticity, when the backpack is fixed, it is in a compressed state, which will cause more wrinkles on the surface of the backpack. The seams of the backpack are the key parts of the waterproof performance. If the backpack is in a compressed state during the test, the seams are blocked and these potential problems may not be discovered. In addition, the shape of the outdoor backpack will change when loading items of different weights and shapes. If the backpack is in a compressed state during the test, it is impossible to simulate the shape of the backpack in actual use, thereby affecting the accuracy of the test results. In addition, when using the outdoor backpack, it may be subjected to physical shock and vibration due to running and climbing. The zippers, fasteners, and seams on the backpack may loosen or deform under vibration and shock, resulting in reduced sealing. In this way, rainwater may penetrate into the backpack through these gaps. The spraying in the above technical solution alone cannot simulate such a situation, affecting the comprehensiveness of the rainproof detection.

In addition, when a depression appears at the striking location, the backpack can be stopped from rotating, and the three splints on both sides can be driven to rotate in different directions at the same time, and the anti-slip protrusions and the surface of the backpack can be used to clamp the two sides of the depression of the backpack.

[0044] Specifically, an outdoor backpack is a type of backpack designed for outdoor activities. It combines practicality, durability and comfort to meet the needs of various sports or leisure activities such as outdoor adventures, hiking, mountaineering, camping, cycling, rock climbing, etc. During the production process, outdoor backpacks need to be tested for rainproof performance. Through rainproof performance testing, it can be ensured that the backpack will not be damaged by rainwater penetration when used on rainy days, thereby extending the service life of the backpack; when using the existing rainproof performance testing device for outdoor backpacks, the backpack is first fixed, then sprayed, and the rainproof performance of the backpack is obtained by observing whether the backpack is filled with water. However, since the backpack has a certain elasticity, when the backpack is fixed, the backpack is in a compressed state, which will cause the surface of the backpack to have more wrinkles, and the seams of the backpack are the key parts of the waterproof performance. If the backpack is in a compressed state during the test, the seams are blocked, and these potential problems may not be found. In addition, when the outdoor backpack is loaded with items of different weights and shapes, its shape will change. If the backpack is in a compressed state during the test, it is impossible to simulate the shape of the backpack in actual use, thereby affecting the accuracy of the test results;

[0045] Therefore, in order to solve the above problems, when using the present embodiment, a certain amount of water is injected into the bottom of the box body 1 through the water injection pipe 33, and then the box door on the front side of the box body 1 is opened. Then, according to the width of the backpack to be detected, the two-way threaded rods 18 on both sides are manually rotated to adjust the spacing between the front and rear clamping plates 10, so that the left edge of the backpack can be placed between the left clamping plate 10 and the second clamping plate 11, and the right edge of the backpack can be placed between the right clamping plate 10 and the second clamping plate 11, and then the plurality of threaded rods 3 5 are rotated to make the second clamping plate 11 move horizontally and cooperate with the first clamping plate 10 to move the backpack. Clamping, when the backpack is clamped, the right support plate 12 can be slid to the right by rotating the threaded rod 13 to stretch the backpack in the left and right directions, and the bidirectional threaded rod 18 can be rotated again to increase the distance between the two sliders 30 to stretch the backpack in the front and back directions, so as to simulate the shape of the backpack when in use, and also reduce the wrinkles on the surface of the backpack, so that the seams are exposed, and then the water at the bottom of the box body 1 is pumped out by the water pump 3, and then sprayed to the backpack from the nozzle 6 after passing through the water outlet pipe 2, and finally, the backpack is taken off to observe the water inflow state of the backpack, so as to know the rainproof performance of the backpack;

[0046] The backpack can be fixed and stretched by the expansion positioning mechanism to simulate the shape of the backpack when loaded with items. At the same time, the problem of the water flow being unable to contact the seams due to the seams of the backpack being blocked by wrinkles is avoided, thereby improving the accuracy of the detection results.

[0047] Furthermore, when the backpack is sprayed, the motor 1 8 and the motor 4 32 can be started at the same time, and the motor 1 8 can drive the rotating frame 9 to rotate, so that the backpack can rotate, so that different sides of the backpack can face the spray head 6, and under the action of the motor 4 32 driving the threaded rod 24 to rotate, the spray head 6 can move back and forth horizontally, so that each position of the backpack can be sprayed evenly, thereby improving the uniformity of the spray, avoiding the spray dead angle, and improving the comprehensiveness of the detection;

[0048] In addition, when an outdoor backpack is in use, it may be subjected to physical shock and vibration due to running and climbing. The zippers, fasteners, and seams on the backpack may become loose or deformed under vibration and shock, resulting in reduced sealing. In this way, rainwater may penetrate into the backpack through these gaps. The above-mentioned spraying alone cannot simulate such a situation. Therefore, during the spraying process, the motor 3 17 can be used to drive the connecting rod 2 16 to rotate, and with the cooperation of the connecting rod 1 15, the striking column 28 can be made to slide back and forth horizontally to strike the backpack and make the backpack vibrate, so as to observe whether the zippers and fasteners of the backpack are loosened due to vibration and shock, and then rainwater penetrates into the backpack, further improving the comprehensiveness of the detection;

[0049] When the striking post 28 strikes the backpack, the striking position will be sunken. When the striking position is sunken, the striking post 28 will not be able to contact the backpack. Therefore, the striking work can be carried out normally. When the striking position is sunken, the backpack stops rotating, and then the motor 2 14 drives the upper clamping plate 3 20 to rotate. Under the action of the gear 22, the clamping plates 3 20 on both sides rotate in different directions at the same time, and the anti-slip protrusions 21 and the surface of the backpack are used to clamp the two sides of the sunken position of the backpack. At this time, the striking post 28 moves to the right again to pull out the sunken position, and then the clamping plate 3 20 is reset. At this time, the striking post 28 can continue to strike the backpack, thereby avoiding the backpack from being partially sunken due to the striking, and then the striking post 28 cannot normally hit the backpack, and the continuous vibration of the backpack is ensured.

[0050] Therefore, by utilizing the reset striking mechanism, during the spraying process, the striking column 28 can be driven to slide back and forth laterally to strike the backpack, causing the backpack to vibrate, and then it can be observed whether the zippers, fasteners, and seams of the backpack are loosened due to vibration and impact, forming water seepage channels, causing rainwater to seep into the backpack, thereby further improving the comprehensiveness of the detection. In addition, when a depression appears at the striking location, the backpack can be stopped from rotating, and the clamping plates 20 on both sides can be driven to rotate in different directions at the same time, and the anti-slip protrusions 21 and the surface of the backpack can be used to clamp the two sides of the depression of the backpack. At this time, the striking column 28 can be moved to the right again to pull out the depression, and the striking column 28 can continue to strike the backpack, thereby avoiding the situation where the backpack is partially depressed due to the striking, and then the striking column 28 cannot strike the backpack normally, thereby ensuring the continuous vibration of the backpack.

[0051] In this embodiment, Figure 1 As shown, a plurality of through holes 27 are provided on the partition plate 26;

[0052] Specifically, the water used in the spraying process will flow into the bottom of the box through the through hole 27, and then the spraying water can be pumped by the water pump 3 to continue the spraying work, thereby realizing the circulation of resources and saving water.

[0053] Working principle: a certain amount of water is injected into the bottom of the box body 1 through the water injection pipe 33, and then the box door on the front side of the box body 1 is opened. Then, according to the width of the backpack to be tested, the two-way threaded rods 18 on both sides are manually rotated to adjust the spacing between the front and rear clamping plates 10, so that the left edge of the backpack can be placed between the left clamping plate 10 and the second clamping plate 11, and the right edge of the backpack can be placed between the right clamping plate 10 and the second clamping plate 11. Then, the plurality of threaded rods 3 5 are rotated to make the second clamping plate 11 move horizontally and cooperate with the first clamping plate 10 to clamp the backpack. When the backpack is clamped, the right support plate 12 can be slid to the right by rotating the threaded rod 13. The backpack can be stretched in the left and right directions by moving the bidirectional threaded rod 18, and the bidirectional threaded rod 18 can be rotated again to increase the spacing between the two sliders 30 to stretch the backpack in the front and back directions, so as to simulate the shape of the backpack when in use, reduce wrinkles on the surface of the backpack, expose the seams, and then use the water pump 3 to pump out the water from the bottom of the box body 1, and spray it from the nozzle 6 to the backpack after passing through the water outlet pipe 2. Finally, the backpack is taken off to observe the water inflow state of the backpack, so as to know the rainproof performance of the backpack; thus, the backpack can be fixed and stretched by using the expansion positioning mechanism to simulate the shape of the backpack when loaded with items, and at the same time, it can also avoid the backpack from being damaged by the back. The seams of the bag are blocked by wrinkles, which makes it impossible for the water flow to contact the seams, thereby improving the accuracy of the detection result; and, when the backpack is sprayed, the motor 1 8 and the motor 4 32 can be started at the same time, and the motor 1 8 can drive the rotating frame 9 to rotate, so that the backpack rotates, so that different sides of the backpack can face the spray head 6, and under the action of the motor 4 32 driving the threaded rod 24 to rotate, the spray head 6 moves back and forth horizontally, so that each position of the backpack can be sprayed evenly, the uniformity of the spray is improved, the spray dead angle is avoided, and the comprehensiveness of the detection is improved; and, when the outdoor backpack is in use, it may be subjected to physical shock and vibration due to running and climbing, The zippers and fasteners on the backpack may become loose or deformed under vibration and impact, resulting in reduced sealing. In this way, rainwater may penetrate into the backpack through these gaps. The above-mentioned spraying alone cannot simulate such a situation. Therefore, during the spraying process, the motor 3 17 can be used to drive the connecting rod 2 16 to rotate, and with the cooperation of the connecting rod 1 15, the striking column 28 can be made to slide back and forth horizontally to strike the backpack and make the backpack vibrate. Then, it can be observed whether the zippers, fasteners, and seams of the backpack are loosened due to vibration and impact, forming a water seepage channel, and rainwater penetrates into the backpack, which further improves the comprehensiveness of the detection.When the striking post 28 strikes the backpack, the striking position will be sunken. When the striking position is sunken, the striking post 28 will not be able to contact the backpack. Therefore, the striking work can be carried out normally. When the striking position is sunken, the backpack can stop rotating, and then the motor 14 drives the upper clamping plate 3 20 to rotate, and under the action of the gear 22, the clamping plates 3 20 on both sides rotate in different directions at the same time, and the anti-slip protrusions 21 and the surface of the backpack are used to clamp the two sides of the sunken position of the backpack. At this time, the striking post 28 moves to the right again to pull out the sunken position, and then the clamping plate 3 20 is reset. At this time, the striking post 28 can continue to strike the backpack, thereby avoiding the situation where the backpack is partially sunken due to the striking, and then the striking post 28 cannot hit the backpack normally, thereby ensuring the continuous vibration of the backpack; thereby, the reset striking mechanism can be used to drive the striking post 28 to move horizontally during the spraying process. The backpack is hit by sliding back and forth, causing the backpack to vibrate, and then it can be observed whether the zipper and fasteners of the backpack are loosened due to vibration and impact, and rainwater seeps into the backpack, which further improves the comprehensiveness of the detection. In addition, when a depression appears at the hitting position, the backpack can be stopped from rotating, and the clamping plates 20 on both sides are driven to rotate in different directions at the same time, and the anti-slip protrusions 21 and the surface of the backpack are used to clamp the two sides of the backpack depression. At this time, the hitting column 28 moves to the right again to pull out the depression, and the hitting column 28 can continue to hit the backpack, avoiding the situation where the backpack is partially depressed due to the hitting, and then the hitting column 28 cannot hit the backpack normally, ensuring the continuous vibration of the backpack, and the water used in the spraying process will flow into the bottom of the box through the through hole 27, and then the spraying water can be pumped by the water pump 3 to continue the spraying work, thereby realizing the circulation of resources and saving water. ;
