Description

Technical Field

[0001] The utility model relates to a down anti-drilling property detector for down. Background Art

[0002] Feather down is a natural material with good fluffiness and resilience. Its products are soft and warm. However, when down is filled into the product, due to its good fluffiness, the down is close to the fabric and has good resilience. No matter which direction it is pressed from, the down can quickly return to its original state. However, the air permeability of anti-drilling down fabric is usually poor, resulting in a large amount of static air stagnating in the down product. When down products are squeezed or rubbed by the outside world, static air leaks out from the pores of the fabric or the needle holes of the sutures, and feathers and down also take the opportunity to drill out with the air to form drilled down. Drilled down not only affects the appearance but also its warmth retention. With the improvement of consumption level, consumers and down product manufacturers pay more and more attention to the anti-drilling down performance of fabrics, and the test of fabric anti-drilling down performance is increasingly valued. In my country's national standards, anti-drilling down performance is expressed by the number of drilled down roots under specified conditions using a fabric anti-drilling down tester.

[0003] In the prior art, for example, the tester described in CN209387654U requires manual counting of the number of downs drilled out of the rotary box after the detection process is completed, and then the downs in the rotary box are cleaned out one by one to avoid affecting the next detection; the counting process is not only easy to cause omissions, but also easy to make the staff dizzy; the cleaning process requires manual sorting out of the downs one by one from the sample opening, which is time-consuming and laborious.

[0004] Therefore, it is necessary to improve the down anti-drilling property detector in the prior art. Utility Model Content

[0005] The utility model aims to overcome the defects in the prior art and provide a down anti-drilling property detector, which is convenient for detection personnel to count the number of downs, avoids the cleaning of the rotary box, and improves the detection efficiency.

[0007] A preferred technical solution is that the fixing assembly includes a Velcro tape arranged between the outer wall of the lining member and the inner wall of the rotary box.

[0008] Preferably, an elastic reset member is provided on the side wall or side of the inner lining member, and the elastic reset member is arranged in close contact with the inner wall of the rotary box.

[0009] Preferably, the rotary box includes an outer box and an inner box. The inner box is fixed in the outer box, a cavity is provided between the inner box and the outer box, the cavity is set to be in negative pressure, a plurality of ventilation holes are provided on the side wall of the inner box, and the inner lining member is arranged in the inner box.

[0010] Preferably, the outer box is provided with a negative pressure port, and a sealing plug is detachably arranged at the negative pressure port.

[0011] Preferably, the negative pressure port is arranged opposite to the picking and placing port.

[0012] Preferably, the cover plate is hermetically connected to the picking and placing port.

[0013] Preferably, sealing strips are provided on the walls of the cover plate that are in close contact with the outer box and the inner box.

[0014] The advantages and beneficial effects of the present utility model are as follows: The down anti-feather leakage detector of the present utility model has a reasonable structure. By providing an inner lining member, the sample to be tested is placed in the inner lining member, and the inner lining member is installed in the rotary box. Then, the test can be started. After the test is completed, the inner lining member can be taken out of the rotary box. The inner lining member is placed on the test bench, and the inspector can count and clean it with confidence, which is convenient for the inspector to count the number of down feathers and avoids the cleaning of the rotary box, improving the test efficiency.

[0027] Embodiment

[0028] As Figures 1-9 shown, the down anti-feather leakage detector of the embodiment includes a base 1 and a rotary box 2 rotatably connected to the base 1. The rotary box 2 is provided with an access opening 3 and a cover plate 4 for opening or closing the access opening 3; it also includes a deformable inner lining member 5, and the inner lining member 5 is detachably and fixedly connected to the inner cavity of the rotary box 2. A fixing component for fixing the inner lining member 5 in the rotary box 2 is provided between the rotary box 2 and the inner lining member 5.

[0029] Through such a design, the sample to be tested is placed in the inner lining member 5, the inner lining member 5 is placed in the rotary box 2 and fixed to the rotary box 2, and then the experiment can be started. After the rotation is completed, the inner lining member 5 is removed and placed on the platform. The inspector can count the number of down feathers calmly and conveniently without having to count the down feathers one by one against the rotary box 2; the inner lining member 5 can be a plastic cloth, a polyester cloth, etc. with a smooth inner surface.

[0030] Specifically, the fixing component includes a magic tape 6 disposed between the outer wall of the inner lining member 5 and the inner wall of the rotary box 2.

[0031] Through such a design, the purpose of detachable connection between the inner lining member 5 and the inner wall of the rotary box 2 is achieved, avoiding the inner lining member 5 from falling off and affecting the experimental process when the rotary box 2 rotates.

[0032] Furthermore, an elastic reset member 7 is disposed on the side wall or side of the inner lining member 5, and the elastic reset member 7 is arranged in contact with the inner wall of the rotary box 2.

[0033] Through such a design, after the inner lining member 5 is inserted into the rotary box 2, it is in contact with the inner wall of the rotary box 2 under the action of the restoring force of the elastic reset member 7; the elastic reset member 7 can be made of easily reset materials such as rubber and silica gel.

[0034] In another specific embodiment, furthermore, the fixing component can also be designed as follows: the rotary box 2 includes an outer box 8 and an inner box 9, the inner box 9 is fixed in the outer box 8, a cavity 10 is provided between the inner box 9 and the outer box 8, the cavity 10 is set to be under negative pressure, and a plurality of ventilation holes 11 are provided on the side wall of the inner box 9, and the inner lining member 5 is disposed in the inner box 9.

[0035] Through such a design, by using negative pressure suction, the phenomenon that the inner lining member 5 falls off from the inner box 9 when the rotary box 2 rotates is avoided; it can also avoid the flexible nature of the magic tape 6 from causing insufficient sample collision and increasing the experimental duration, thus affecting the experimental efficiency.

[0036] Specifically, the outer box 8 is provided with a negative pressure port 12, and a sealing plug 13 is detachably provided at the negative pressure port 12.

[0037] Through such a design, the purpose of achieving negative pressure in the cavity 10 is realized.

[0038] Furthermore, the negative pressure port 12 is disposed opposite to the access port 3.

[0039] Through such a design, the influence of the center of gravity offset of the rotary box 2 is reduced.

[0040] Specifically, the cover plate 4 is sealingly connected to the access port 3.

[0041] Through such a design, the negative pressure in the cavity 10 is prevented from being affected by the access port 3.

[0042] Specifically, sealing strips 14 are provided on the walls of the cover plate 4 that are in contact with the outer box 8 and the inner box 9.

[0043] Through such a design, the air communication between the cavity 10 and the inner box 9 is avoided.

[0044] The inner lining 5 can be made of materials such as plastic cloth or polyester cloth with a smooth inner surface, which do not affect the test results.

[0045] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
