[0019] In order to elaborate in detail the technical solutions adopted by the present utility model to achieve the predetermined technical purposes, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only partial embodiments of the present utility model, rather than all embodiments, and, without creative efforts, the technical means or technical features in the embodiments of the present utility model can be replaced. The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0020] As Figure 1 and Figure 2 shown, a thermal conductivity testing device for an antibacterial and cool-sensing fabric of the present utility model includes a base 1, a heating box body 2, a fixing bracket 3 for an antibacterial and cool-sensing fabric, and a thermal conductivity detection box body 4. The heating box body 2 is fixed on the upper side of the base 1. The lower end of the fixing bracket 3 for an antibacterial and cool-sensing fabric is detachably arranged on the upper end of the heating box body 2. The lower end of the thermal conductivity detection box body 4 is detachably arranged on the upper end of the fixing bracket 3 for an antibacterial and cool-sensing fabric. The thermal conductivity detection box body 4 is connected to the heating box body 2 by a locking mechanism. A first thermocouple 5 is arranged in the heating box body 2, and a second thermocouple 6 is arranged in the thermal conductivity detection box body 4.

[0021] An infrared heater 7 is arranged at the bottom of the heating box body 2. The internal cavity of the heating box body 2 is heated by the infrared heater 7 and heated to about 37°C to simulate the normal human body temperature.

[0022] A horizontal partition 8 is provided inside the heating box body 2. The horizontal partition 8 is horizontally fixed inside the heating box body 2 to divide the inner cavity of the heating box body 2 into a lower heating cavity and an upper heating cavity. A plurality of heat conduction holes 9 are formed around the horizontal partition 8. The first thermocouple 5 is arranged inside the upper heating cavity. Since the heating of the infrared heater 7 itself has a certain radiation, in order to prevent the infrared heater 7 from directly radiating and heating the antibacterial cool feeling fabric on the upper side, the horizontal partition 8 is added, so as to ensure that the infrared heater 7 only directly heats the lower heating cavity, and the upper heating cavity forms a heat convection through the heat conduction holes 9 for indirect heating. When the first thermocouple 5 detects that the temperature reaches 37 °C, the heating stops.

[0023] At the upper end of the heating box body 2, a first step groove matching the lower end of the antibacterial cool feeling fabric fixing bracket 3 is provided. The lower end of the antibacterial cool feeling fabric fixing bracket 3 is embedded in the first step groove at the upper end of the heating box body 2. At the lower end of the heat conduction detection box body 4, a second step groove matching the upper end of the antibacterial cool feeling fabric fixing bracket 3 is provided. The upper end of the antibacterial cool feeling fabric fixing bracket 3 is embedded in the second step groove at the lower end of the heat conduction detection box body 4. Through the connection method of the step groove, the installation of the antibacterial cool feeling fabric fixing bracket 3 and the heat conduction detection box body 4 is made simpler and more convenient.

[0024] The locking mechanism includes a plurality of screw locking mechanisms. The plurality of screw locking mechanisms are divided into two groups and symmetrically arranged on both sides of the heating box body 2 and the heat conduction detection box body 4. Each screw locking mechanism includes a locking screw 10, a screw fixing bracket 11, a locking bracket 12 and a butterfly locking nut 13. The screw fixing bracket 11 is fixed on the outer side surface of the heating box body 2. The lower end of the locking screw 10 is hinged on the screw fixing bracket 11. The locking bracket 12 is fixed on the outer side surface of the heat conduction detection box body 4. A groove matching the locking screw 10 is provided on the outer side of the locking bracket 12. The butterfly locking nut 13 is sleeved on the upper end of the locking screw 10 and is threadedly connected with the locking screw 11. The upper end of the locking screw 11 is clamped in the groove on the outer side of the locking bracket 12 and is locked and fixed by the butterfly locking nut 13. After the antibacterial cool feeling fabric fixing bracket 3 and the heat conduction detection box body 4 are sequentially installed on the heating box body 2, the locking screw 10 is rotated upward and clamped into the groove of the locking bracket 12, and then the butterfly locking nut 13 is rotated to lock and fix the locking screw 10.

[0025] As Figure 3 shown, the antibacterial cool feeling fabric fixing bracket 3 is an annular bracket. An annular support plate 14 protruding from the inner wall of the antibacterial cool feeling fabric fixing bracket 3 is arranged inside the antibacterial cool feeling fabric fixing bracket 3. The antibacterial cool feeling fabric 15 is flattened and arranged inside the antibacterial cool feeling fabric fixing bracket 3. The lower sides of the four peripheral edges of the antibacterial cool feeling fabric 15 are arranged on the annular support plate 14 and fixed by a pressing mechanism.

[0026] As Figure 4As shown in the figure, the hemming mechanism includes a hemming pressing plate 16, which is arranged along the periphery of the annular support plate 14. One side of the hemming pressing plate 16 is hinged to the upper side of the annular support plate 14 through a hinge shaft, and a torsion spring is arranged on the hinge shaft. The lower end of the other side of the hemming pressing plate 16 is provided with a serrated structure 17. The torsion spring provides a downward pressure on the hemming pressing plate 16 to press and fix the antibacterial and cool-sensing fabric 15 on the upper side of the annular support plate 14. The serrated structure 17 can increase the bite on the antibacterial and cool-sensing fabric 15 and prevent the fabric from falling off.

[0027] An insulating board 18 is arranged inside the antibacterial and cool-sensing fabric fixing bracket 3. The insulating board 18 is located below the annular support plate 14. A perforation matching the insulating board 18 is opened on one side of the antibacterial and cool-sensing fabric fixing bracket 3, and a sliding groove matching the insulating board 18 is opened on the inner wall of the antibacterial and cool-sensing fabric fixing bracket 3. The insulating board 18 is inserted into the antibacterial and cool-sensing fabric fixing bracket 3 along the perforation of the antibacterial and cool-sensing fabric fixing bracket 3 and slides along the sliding groove to the other side of the antibacterial and cool-sensing fabric fixing bracket 3. A handle is arranged on the side of the insulating board 18 away from the antibacterial and cool-sensing fabric fixing bracket 3. When in use and during installation, the insulating board 18 is inserted into the antibacterial and cool-sensing fabric fixing bracket 3. When the temperature in the heating box body 2 reaches the experimental temperature, the insulating board 18 is pulled out for the experiment to ensure the accuracy of the test.
