Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of natural leather detection equipment, more specifically, it relates to a kind of natural leather air permeability detection device. BACKGROUND

[0002] Natural leather air permeability detection device, i.e. leather air permeability tester, is a device specially used for evaluating the air permeability of leather material.

[0003] The existing natural leather air permeability detection device places the leather between two transparent cups during testing, and the two transparent cups are respectively attached to the leather. The upper cup is filled with water, and the lower cup is pressed by gas. If bubbles appear in the water in the upper cup, it indicates that the leather has air permeability, otherwise it does not. Currently, the lower cup is manually placed on the upper cup, and the two transparent cups are clamped on both sides by buckles. The upper cup is prone to positional deviation during placement. Positional deviation leads to poor sealing between the upper and lower cups, affecting the application of gas pressure and the sealing state of water. If the seal is not tight, even if the leather itself has air permeability, bubbles cannot be observed due to gas escaping from the poor seal, resulting in inaccurate test results.

[0004] Therefore, a new solution is needed to solve this problem. SUMMARY

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a natural leather air permeability detection device. The first transparent cup is fixed on the base, the second transparent cup is fixed on the movable plate, and the second transparent cup is located above the first transparent cup. The axis of the first transparent cup and the second transparent cup coincides. When the second transparent cup is moved downward by the air cylinder and contacts the upper surface of the leather, the air cylinder applies pressure to the second transparent cup, so that the second transparent cup and the first transparent cup cooperate with the leather to be firmly and tightly fixed, preventing positional deviation between the two transparent cups and improving the sealing between the upper and lower cups. At the same time, rubber sealing rings are arranged in the first transparent cup and the second transparent cup to improve the sealing, thereby improving the accuracy of the leather air permeability test results.

[0006] The utility model discloses a technical purpose above is realized through the following technical schemes: a natural leather's air permeability detection device, including the base, the upper end middle side fixed mounting of base has the first transparent cup, the right side fixed mounting of first transparent cup has the trachea, one end fixed mounting of trachea has the gasbag, the upper end left side fixed mounting of base has the fixed frame, the upper end fixed mounting of fixed frame has the pneumatic cylinder, the output fixed mounting of pneumatic cylinder has movable board, the upper end right side fixed insertion connection of movable board has the second transparent cup, the second transparent cup is through from top to bottom, the axis line of first transparent cup and second transparent cup coincides, the upper end left side fixed connection of movable board has the limit rod, and the limit rod and fixed frame movable insertion connection.

[0007] The utility model further sets up: the inner chamber upper portion of first transparent cup and the inner chamber lower portion of second transparent cup all fixed mounting have a rubber seal ring.

[0008] The utility model further sets up: the lower end fixed mounting of base has four support legs.

[0009] The utility model further sets up: the fixed frame is L shape setting.

[0010] The utility model further sets up: movable board and base keep parallel positional relation.

[0011] Summarized above, the utility model has following beneficial effect:

[0012] 1, through first transparent cup fixed on the base, second transparent cup is fixed on movable board, and second transparent cup is located the upper of first transparent cup, and the axis line of first transparent cup and second transparent cup coincides, through starting pneumatic cylinder and push second transparent cup and move down and contact the upper surface of leather, and pneumatic cylinder carries out pressure to second transparent cup, thereby make second transparent cup and first transparent cup cooperate leather fixed firm and compact, prevent the positional deviation between two transparent cups, improve the sealing between the upper and lower cup, and set up rubber seal ring in first transparent cup and second transparent cup to improve the sealing, thereby improve the accuracy of leather air permeability test result.
