[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0019] A preferred embodiment of the present utility model provides a device for detecting the number of door openings and closings.

[0020] like Figures 1 to 2 As shown, the device includes a base 1, on which a main bracket 2 and a sub-bracket 3 are fixedly mounted. The main bracket 2 is a vertical frame structure for mounting a door body 4 to be tested, and the sub-bracket 3 is also a vertical frame structure. The main bracket 2 and the sub-bracket 3 are fixedly connected to increase overall stability.

[0021] Two guide columns 5 are provided on the sub-bracket 3 along the up and down directions. The two guide columns 5 are arranged in parallel. A mounting seat 6 is slidably installed on the two guide columns 5. A screw rod (not shown in the figure) is also provided between the two guide columns 5. The screw rod is arranged parallel to the guide columns 5 and is rotatably installed on the sub-bracket 3 through a bearing. A threaded through hole is provided on the mounting seat 6. The screw rod is threadedly connected to the threaded through hole. A handwheel is provided on the top of the screw rod. Turning the handwheel can drive the mounting seat 6 to slide along the guide columns 5, that is, the height of the mounting seat 6 can be adjusted.

[0022] A motor 7 and an adapter block 8 are mounted on the mounting base 6. The motor 7 is fixedly mounted, and the output shaft of the motor 7 is arranged upward. A turntable 9 is mounted on the output shaft of the motor 7. A rotating shaft 10 is fixedly and vertically mounted on the outer side surface (i.e., the top surface) of the turntable 9.

[0023] The adapter block 8 is rotatably mounted through a bearing, and a swing arm 11 is fixedly mounted on the adapter block 8. The swing arm 11 is arranged in the horizontal direction, and the swing arm 11 is divided into two sections in the length direction with the adapter block 8 as the dividing point. A slider 12 is installed on each section. Specifically, the slider 12 is provided with a through hole that is compatible with the swing arm 11. The slider 12 can be slidably mounted on the swing arm 11. By sliding the slider 12, the position of the slider 12 on the installed section can be adjusted arbitrarily and fixed by a top screw.

[0024] By adjusting the positions of the two sliders 12 in their respective sections, the door bodies 4 to be tested with different widths can be adapted, and the size of the opening angle of the door body 4 to be tested can also be adjusted.

[0025] The first slider is connected to the rotating shaft 10 through a first connecting rod 13. Specifically, a sleeve 14 is provided at one end of the first connecting rod 13, and the sleeve 14 is rotatably mounted on the rotating shaft 10. A first slot is provided on the first slider, and the other end of the first connecting rod 13 extends into the first slot and is rotatably connected through a pin shaft.

[0026] The second slider is hinged with a second connecting rod 15. Specifically, a second slot is provided on the second slider. One end of the second connecting rod 15 extends into the second slot and is rotatably connected through a pin shaft. The other end of the second connecting rod 15 is connected to a suction cup 16, which is adsorbed on the door body 4 to be tested.

[0027] The motor 7 drives the turntable 9 to rotate, and through the transmission of the first connecting rod 13, the two ends of the swing arm 11 are crossed and swung back and forth, thereby realizing the continuous opening and closing of the door body 4 to be tested.

[0028] Furthermore, the device also includes an electromagnetic induction counter (but not shown in the figure). The probe of the electromagnetic induction counter is set on the mounting base 6, and the induction magnet of the electromagnetic induction counter is set on the adapter block 8, which is used to measure the number of times the door body 4 to be measured is opened and closed. The specific working principle of the electromagnetic induction counter can be referred to the existing technology and will not be repeated here.

[0029] In summary, the door opening and closing frequency detection device described in the embodiment of the present invention can adjust the vertical position of the suction cup by adjusting the height of the mounting base, and the left and right position of the suction cup by adjusting the positions of the two sliders. This allows the suction cup to be attached to different positions on the door to be tested, thereby adapting to doors of different sizes. Furthermore, the device has a simple structure, flexible design, low manufacturing cost, and strong practicality.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
