[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0025] The present invention will be further described below with reference to the embodiments.
[0026] Example: Refer to Figures 1 to 3 A waterproof testing device for finished leather products, comprising a test chamber 1;
[0027] The testing mechanism includes a lifting component 2, a bending component 3, and two fixing components 4. The lifting component 2 includes a mounting frame 21 fixedly connected to the upper surface of the test box 1. An electric push rod 22 is fixedly connected to the inner top surface of the mounting frame 21. The output end of the electric push rod 22 is fixedly connected to a first-order C-shaped frame 23.
[0028] The bending assembly 3 includes a motor 31 fixedly connected to the side wall of the first C-shaped frame 23 via a bracket. The output end of the motor 31 is fixedly connected to a bidirectional threaded rod 32. The bidirectional threaded rod 32 is rotatably connected to the two side walls of the first C-shaped frame 23 via bearings. Nuts 33 are threadedly connected to the threaded sections of the bidirectional threaded rod 32 with opposite thread directions. Two limiting grooves 34 are opened on the upper surface of the first C-shaped frame 23. Limiting blocks 35 are slidably connected in the two limiting grooves 34. The two limiting blocks 35 are fixedly connected to the upper surfaces of the two nuts 33 respectively. The bottom surfaces of the two nuts 33 are rotatably connected to opening and closing plates 36 via pins. The two opening and closing plates 36 are hinged together. The two side walls of the limiting blocks 35 are in contact with the two inner walls of the limiting grooves 34.
[0029] The fixing component 4 includes two cross-shaped through slots 41 formed on the side wall of the opening and closing plate 36. A cross-shaped slider 42 is slidably connected within each of the two cross-shaped through slots 41. A spring 43 is fixedly connected between each of the two cross-shaped sliders 42 and the inner wall of each of the two cross-shaped through slots 41. A second-order C-shaped bracket 44 is fixedly connected to the side wall of each of the two second-order C-shaped brackets 44. A threaded through hole 45 is formed on the side wall of each of the two threaded through holes 45. A fixing threaded rod 46 is threadedly connected within each of the two threaded through holes 45. The side ends of the two fixing threaded rods 46... Each component is rotatably connected to a pressure plate 47 via a bearing. Two fixing components 4 are respectively fixed on two opening and closing plates 36. Through the cooperation of the two fixing components 4, the leather to be tested is securely fixed. Knobs are fixedly connected to the side ends of multiple fixing threaded rods 46 for easy operation by staff. Multiple springs 43 are respectively located in multiple cross slots 41. The side wall of the pressure plate 47 near the second cubital frame 44 is in contact with the inner wall of the second cubital frame 44 to ensure that the fixing components 4 can operate normally.
[0030] The working principle of this utility model is as follows: When using this waterproof testing equipment for finished leather products, the finished leather product to be tested is first placed on two opening plates 36 and fixed by the fixing component 4. The knob on the side of the fixing threaded rod 46 is rotated, which drives the fixing threaded rod 46 to rotate in the threaded through hole 45, thereby pushing the pressure plate 47 to move inward to the inner side of the second cubit frame 44, clamping the edge of the leather between the pressure plate 47 and the second cubit frame 44. During the fixing process, the cross slider 42 can slide in the cross through groove 41, and the spring 43 plays a buffering role, which can adapt to leather of different lengths and ensure a firm fixation.
[0031] After fixing, start the electric push rod 22. The output end of the electric push rod 22 extends, driving the No. 1 C-shaped frame 23 and the bending component 3 and fixing component 4 below to descend, so that the leather is immersed in the water in the test chamber 1 for waterproof testing.
[0032] To simulate the waterproof performance of leather under bending conditions, start motor 31. Motor 31 drives bidirectional threaded rod 32 to rotate. Since the two threads of bidirectional threaded rod 32 are in opposite directions and nut 33 cannot rotate under the restriction of limit block 35 and limit groove 34, the two nuts 33 will move in opposite directions along bidirectional threaded rod 32. Nut 33 drives opening and closing plate 36 to move. The two opening and closing plates 36 open and close around the hinge point, thereby bending the leather to simulate the bending scenario in actual use. The bending angle can be adjusted as needed to better meet the actual testing requirements.
[0033] After the test is completed, turn off the motor 31 and the electric push rod 22. The output end of the electric push rod 22 retracts, causing all components to rise. Loosen the fixing component 4, remove the leather, and observe the water seepage of the leather to complete the test.
[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
