DETAILED DESCRIPTION

In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

As shown in Figures 1 to 4, an automatic tester for the washability and waterproof performance of shoes includes a box body 1, wherein a water tank for containing water is provided in the box body 1, a sample fixing component is provided in the water tank, a plurality of water immersion sensors are provided in the sample fixing component, and a washing component is provided next to the water tank sample fixing component.

In this embodiment, the brushing assembly includes a telescopic cylinder 2, which is mounted on the side wall of the box 1, a rotating motor 3 is mounted on the telescopic cylinder 2, a brushing base is mounted on the rotating motor 3, a brushing arm 5 is swingably mounted on the brushing base, and a shoe brush 6 is mounted on the end of the brushing arm 5. When the rotating motor 3 is driven forward and reverse, the shoe brush can be swept back and forth horizontally, and when the telescopic cylinder is driven forward and reverse, the shoe brush can be swept back and forth longitudinally. The rotating motor and the telescopic cylinder are respectively connected to counters, and the counters are prior art (the counters are connected to record the rotation value of the motor or the extension value of the telescopic cylinder, thereby recording the number of times the shoe brush is brushed), which will not be described in detail here.

The telescopic cylinder 2 is installed on the side wall of the box body through a detachable bracket. The detachable bracket and the box body 1 are detachably connected through a bolt assembly, which is convenient for adjusting the height of the detachable bracket. The rotating motor 3 and the detachable bracket can be slidably connected through a slide rail and a slider assembly, which is convenient for the telescopic cylinder 2 to control the reciprocating movement of the rotating motor 3.

In this embodiment, the sample fixing assembly includes a shoe last 7 , a fixing arm 8 is disposed on the top of the shoe last 7 , and the fixing arm 8 is mounted on a supporting rod 9 , and the supporting rod 9 is swingably mounted on the box 1 .

In this embodiment, an arc-shaped groove 10 for the support rod 9 to swing is opened on the side wall of the box body 1, and a control handle is provided at the end of the support rod 9.

In this embodiment, the support rod 9 is provided with a roller 11 at the arc groove 10, and the outer side of the roller 11 extends to form a limiting plate 12, and a limiting hole 13 is provided on the limiting plate 12, and a plurality of positioning holes corresponding to the limiting hole 13 are provided on the box body.

In this embodiment, a support seat 14 is installed in the water tank, and a support plate 15 is rotatably installed on the support seat 14. A rotating shaft 16 is installed at one end of the support plate 15, and one end of the rotating shaft 16 extends out of the box body 1. A connecting rod 17 is arranged between the rotating shaft 16 and the support rod 9.

The placement angle of the support plate 15 is adjusted by changing the relative position of the limit plate 12, thereby adjusting the inclined surface of the experimental shoe body 19. When the experimental shoe body 19 is placed at an angle, the cleaning component can perform a sufficient cleaning test on the side of the experimental shoe body 19 to avoid the defect that the cleaning component cannot clean the side of the shoe body when the shoe body is placed normally.

In this embodiment, an air bag 18 is provided on the upper surface of the shoe last 7, and the plurality of water immersion sensors are mounted on the surface of the air bag 18. When in use, the air bag 18 will be inflated and will fit upwardly on the inner side of the experimental shoe body 19, ensuring that the water immersion sensor can receive the signal of water leakage from the upper membrane of the experimental shoe body 19 in time.

In this embodiment, the inflatable bag 18 includes a shoe upper portion and a shoe opening portion, the shoe upper portion covers the upper surface of the shoe last 7, and the shoe opening portion wraps the top of the shoe last 7 in a ring shape, so that the inflatable bag 18 can just support the shoe opening of the experimental shoe body 19, thereby preventing the water drop test in the box 1 from splashing into the shoe and affecting the test results.

In this embodiment, an air storage cavity 20 is provided in the shoe last 7, and the air storage cavity 20 is a closed space. A detachable cover is provided on the top of the shoe last 7, and the cover is installed at the bottom of the fixed arm 8. The cover and the shoe last 7 can be locked by threaded sealing. An air flow channel 21 connecting the air storage cavity 20 and the air bag 18 is provided at the upper of the shoe last 7. A compression block 22 is movably provided in the air storage cavity 20, and a compression mechanism for controlling the movement of the compression block 22 is provided on the shoe last 7. The air storage space of the air storage cavity 20 from the compression block 22 to the air bag is gradually reduced, which is convenient for the inflation and recovery of the air bag 18.

In this embodiment, the compression mechanism includes a swing shaft 23 and a telescopic rod 24. The swing shaft 23 is rotatably installed in the shoe last 7. One side of the swing shaft 23 extends out of the shoe last 7 and is provided with a control paddle. An eccentric wheel 25 is provided in the middle of the swing shaft 23. The outer edge end of the eccentric wheel 25 is in contact with the top of the telescopic rod 24. The compression block 22 is located below the telescopic rod 24.

In this embodiment, the telescopic rod 24 includes a rod head and a rod body, the diameter of the rod head is larger than the diameter of the rod body, a limit plate 27 is provided below the rod head in the shoe last 7, a circular hole is provided on the limit plate 27 for the rod to pass through, and a spring 28 is provided between the limit plate and the rod head.

A spiral groove 29 is provided on the rod head, and a guide column 30 corresponding to the spiral groove 29 is provided on the inner wall of the shoe last 7. A first magnet 31 is provided at the bottom of the rod body, and the first magnet 31 is located below the limiting plate 27. A second magnet 32 is provided on the top of the compression block 22, and a card block is provided at the outer edge of the second magnet 32. A card slot for embedding the card block is provided on the inner wall of the shoe last 7. The first magnet 31 and the second magnet 32 are controlled to attract or repel each other by the rotation of the first magnet 31. A pull rope 33 is provided between the middle parts of the first magnet 31 and the second magnet 32, and the pull rope 33 can prevent the two magnets from being too far apart.

During operation, the swing shaft 23 is controlled to rotate by the paddle, and the swing shaft 23 drives the eccentric wheel 25 to rotate. The eccentric wheel 25 pushes the telescopic rod 24 to slide down. While the rod head slides down, it is affected by the guide column 30 to spiral downward. The rod body drives the first magnet 31 to rotate. Since the outer edge end of the second magnet 32 is stuck, it will not rotate with it, thereby forming a state of mutual repulsion between the first magnet and the second magnet. At this time, the compression block 22 is driven downward by the second magnet 32 to compress the gas in the air storage chamber 20, so that the gas flows to the airbag 18.

The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification, equalization change and modification made to the above embodiment by any technician familiar with the field without departing from the content of the technical solution of the present invention according to the technical essence of the present invention shall fall within the scope of the present invention.
