[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-5 A wireless on-site testing device for wall heat transfer coefficient includes a tester 1, a control terminal 2 mounted on the top of the tester 1, a cover 3 on the surface of the tester 1, a connecting plate 4 mounted on the bottom of the tester 1, and a base 5 connected to the bottom of the connecting plate 4; a first screw 6 is rotatably connected inside the base 5, and movable blocks 7 are threadedly connected to both sides of the surface of the first screw 6; a partition 8 is provided at the top of the movable block 7, and a rotating shaft 9 is mounted on one side of the partition 8; a support bar 10 is connected to the surface of the rotating shaft 9, and a mounting plate 11 is connected to the top of the support bar 10. The top of the mounting plate 11 is equipped with a pulley 12. By rotating the first screw 6, the moving block 7 connected to its surface thread can move the support bar 10 and the mounting plate 11. The pulley 12 installed at the bottom of the mounting plate 11 can be moved to the ground and contact the ground to lift the base 5. Thus, the detector 1 and other items can be moved by the pulley 12. The operation is simple. The support bar 10 and the mounting plate 11 are also connected by a rotating shaft 9 and a partition 8, which makes it easy for the support bar 10 to move the mounting plate 11 when it moves.

[0030] Furthermore, a movable rod is connected to one side of the movable block 7 and is slidably connected to the inner wall of the base 5. This is to facilitate the movable block 7, which is threaded to the surface of the first screw 6, to move in a limited position on the inner wall of the base 5 through the movable rod when the first screw 6 rotates.

[0031] Furthermore, the threads on both sides of the surface of the first screw 6 are arranged in opposite directions, which is to facilitate the simultaneous movement of the moving blocks 7 connected to the threads on both sides of the surface of the first screw 6 in the opposite direction or in the opposite direction when the first screw 6 rotates.

[0032] Furthermore, the base 5 is internally rotatably connected to a second screw 13 that is threadedly connected to the connecting plate 4, and the base 5 is internally fixedly connected to a guide rod 14 that is movably sleeved with the connecting plate 4. This allows the connecting plate 4, which is threadedly connected to its surface, to be limited and moved on the surface of the guide rod 14 by rotating the second screw 13, thereby driving the detector 1 on the connecting plate 4 to move, so as to move the detector 1 to a designated position according to the specific situation.

[0033] Furthermore, a rotating rod 15 is rotatably connected to the surface of the cover 3, and the rotating rod 15 passes through the cover 3 and is connected to a first bevel gear 16. Second bevel gears 17 are evenly distributed in a ring on the surface of the first bevel gear 16, and a third screw 18 is connected to one side of the second bevel gear 17. A fixing tube 19 connected to the surface of the detector 1 is threaded to the surface of the third screw 18. Fixing holes are opened around the surface of the detector 1, and the fixing tube 19 is in contact with the inside of the fixing holes. By rotating the rotating rod 15 and the first bevel gear 16, the second bevel gears 17 meshing with the surface of the first bevel gear 16 can drive the third screw 18 to rotate, thereby moving the fixing tube 19 on the surface of the third screw 18 to move the fixing tube 19 into the fixing hole, so that the cover 3 can be installed without the need to use bolts to install the cover 3, making the operation relatively simple.

[0034] Furthermore, a ring of grooves 20 are evenly distributed on one side of the cover 3, and a slider 21 is slidably connected inside the grooves 20. The top of the slider 21 is connected to a first connecting rod 22 that is connected to the fixed tube 19. This is to facilitate the fixed tube 19 on its surface to be limited and moved by the slider 21, the grooves 20 and the first connecting rod 22 when the third screw 18 rotates.

[0035] Furthermore, a bearing 23 is mounted on the surface of the third screw 18, and a second connecting rod 24 connected to the cover 3 is connected to the bottom end of the bearing 23. This facilitates the support and limiting of the third screw 18 through the bearing 23 and the second connecting rod 24, allowing it to rotate in its original position.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
