[0021] The present application is further described in detail below in conjunction with the accompanying drawings.
[0022] In order to more clearly understand the technical solution presented in the embodiments of the present application, the working principle of an existing door and window thermal insulation performance detection device is first introduced.
[0023] The existing door and window thermal insulation performance testing equipment is divided into two types: precision and simple types. The precision type can obtain various values of door and window thermal insulation more accurately, and the simple type can obtain some basic data of doors and windows. For ordinary buildings, the simple type testing equipment can meet the corresponding needs. The present application is in the direction of simple type testing equipment. The existing simple type testing equipment increases the temperature on one side of the door and window by heating, sun exposure, etc., and then observes and records the temperature change value on the other side to obtain the temperature change time, change speed, change value and other data on the other side, and then obtains the detection structure. The thermal insulation of the door and window is obtained through analysis. However, the detection structure is relatively simple. Sometimes the door and window are heavy and the connection is not firm, which may cause them to fall over and cause accidents. Therefore, it is necessary to improve the existing detection structure to solve these problems.
[0024] See also Figure 1, is a door and window thermal insulation performance detection device disclosed in an embodiment of the present application, comprising a mounting plate 1, a box body 2, a partition 3, a connecting bar 4, a connecting block A5, a connecting block B6, a temperature sensor 7, a display module 8, a slide 9, a movable block 10, a connecting frame 11 and a heating wire 12, the box body 2 is fixedly connected to the rear end of the mounting plate 1, the front and rear sides of the box body 2 are connected, the partition 3 is fixedly connected to the middle of the box body 2, and the partition 3 divides the internal space of the box body 2 into two equal rectangular cavities, the connecting bar 4 is fixedly connected to the front ends of the left and right sides of the box body 2, and the connecting block A5 is fixedly connected to the upper and lower sides of the partition 3 On the front side surfaces of the box body 2 corresponding to the two ends, the connecting blocks B6 are respectively fixedly connected to the front side surfaces of the box body 2 corresponding to the middle part of the connecting bar 4, the temperature sensors 7 are respectively fixedly connected to the four inner walls of each rectangular cavity of the box body 2, the display module 8 is fixedly connected to the upper end of the box body 2, the output ends of the temperature sensors 7 are respectively electrically connected to the input ends of the display module 8, the slide grooves 9 are symmetrically opened on the upper surface of the mounting plate 1, the movable block 10 is slidably connected in the slide grooves 9, the connecting frame 11 is fixedly connected to the upper end of the movable block 10, the heating wires 12 are fixedly connected, and the heating wires 12 are arranged in sequence in an S shape.

The setting of the box body 2 can allow the heat passing through the doors and windows during the detection process to pass through, effectively improving the accuracy of the detection process, and can be used for detection in more environments. The use of the partition 3 can divide the space inside the box body 2, so that two spaces are formed inside the box body 2, and more spaces can be divided as needed. The temperature sensors 7 are installed in the two spaces respectively, so that two or more groups of experimental data can be obtained in one experiment, which effectively improves the efficiency of the detection. The connection bar 4 and the connection block A are set 5 and the connecting block B6 can connect and fix the doors and windows, so that the door body or the window body is firmly connected to the front side of the box body 2. When in use, the heating wire 12 connected to the connecting frame 11 generates heat, and then moves the position of the movable block 10 in the slide groove 9, changes the distance between the heating wire 12 and the door and window, and after a certain period of time, the temperature sensor 7 obtains the temperature change value in the box body 2, and transmits it to the display module 8 in the form of an electrical signal, and records and displays it through the display module 8. The core component of the display module 8 adopts a programmable single-chip microcomputer, which is convenient for subsequent improvement and upgrading, easy to operate, and has a good application prospect.
