[0025] The working principle of the present invention is as follows:

[0026] In the present design, the detection stand 5 is composed of a left frame 51, a front frame 52, a right frame 53 and a rear frame 54 to form a rectangular frame structure; an L-shaped connecting plate 12 is used at the connection between the left frame 51, the front frame 52, the right frame 53 and the rear frame 54, and two screw holes are provided on the horizontal plate body and the vertical plate body of the L-shaped connecting plate 12. On the connection between the left frame 51, the front frame 52, the right frame 53 and the rear frame 54, two screw holes are also provided at the position of the screw holes of the L-shaped connecting plate 12, so as to facilitate the use of screws for fixing; four L-shaped connecting plates 12 are used to connect and fix the left frame 51, the front frame 52, the right frame 53 and the rear frame 54 to form a rectangular frame-type detection stand 5.

[0027] In this design, pressure sensors are installed on the top of the pressure plates 1, 2, 3 and 4 of the left detection component 6, the front detection component 7, the right detection component 8 and the rear detection component 9, so that the controller 11 can be used to conveniently control the detection cylinders 1, 2, 3 and 4 to apply a force of 150N on all sides of the toilet cover 13.

[0028] When the present design starts to detect, the controller 11 controls the detection cylinder 61 in the left detection assembly 6 to move, and drives the connecting rod 63 connected thereto to move synchronously toward the left end of the toilet cover 13 through its piston rod, and at the same time drives the guide wheel of the linkage rod 64 linked thereto to move on the rear frame guide rail 541 on the top surface of the rear frame 54; when the pressure plate 65 on the outer end of the connecting rod 63 reaches the left end of the protruding portion 131 at the rear of the toilet cover 13, the position sensor probe 66 sends a data signal L1 to the controller 11, and the protruding portion at the rear of the cover moves. The distance between the left end of 131 and the position sensing receiver 67 is L1, and L1 is the initial value; then the controller 11 controls the detection cylinder 61 to apply a force of 150N. When the protruding portion 131 at the rear of the cover plate is deformed, the distance between the position sensor probe 66 and the position sensing receiver 67 in this state is L2. When the data signal L2 is sent to the controller 11, the greater the difference between L1 and L2, the smaller the strength of the toilet cover plate 13; the smaller the difference between L1 and L2, the greater the strength of the toilet cover plate 13.

[0029] Similarly, the controller 11 is used to control the front detection component 7, the right detection component 8, and the rear detection component 9 to implement strength detection of the front, right, and rear of the toilet seat cover 13, and the operation steps are the same as above.

[0030] In this design, the difference between L1 and L2 is 0.05-0.15 cm, which indicates good strength. If the difference between L1 and L2 is greater than 0.15 cm, it means that the strength of this part of the toilet seat cover 13 is poor.

[0031] In this design, the controller controls the detection cylinder, position sensor, and pressure sensor. The circuits involved can be easily implemented by technicians in this industry and belong to the prior art. After receiving the two L1 and L2 data sent back by each position sensor, the controller can use the controller to achieve real-time subtraction, so as to obtain the strength data value (L1-L2 difference) around the toilet cover 13, so as to determine the installation strength of the toilet cover 13 in the first time.

[0032] The smart toilet cover installation strength detection device described in the present invention solves the problems of the lack of special detection equipment for the installation strength of the smart toilet cover and the inaccurate application point caused by different measurement points due to covers of different shapes. It can ensure the accuracy of the smart toilet cover installation strength detection results, thereby more effectively determining whether the standard requirements are met.

[0033] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
