[0013] The utility model is described in detail below in conjunction with specific implementation methods:

[0014] like Figures 1 to 3The flatness testing mechanism of a smart toilet cover shown in the figure includes a frame body 1, a carrier plate 2, a first rotating shaft 3, a driving motor 31, a rotating plate 32, a first test rod 33, a bracket 4, a second test rod 41, a sliding sleeve 5, a second rotating shaft 51, a push plate 52, a guide rod 53 and a lock nut 7. The carrier plate 2 is fixedly installed inside the frame body 1, the driving motor 31 is fixedly installed on the carrier plate 2, the first rotating shaft 3 is rotatably installed on the top of the frame body 1 through a first ball bearing, the retaining frame of the first ball bearing is fixedly installed on the top of the frame body 1, the first rotating shaft 3 is fixedly connected to the rotating body of the first ball bearing, and the driving motor The output shaft of 31 is transmission connected with the first rotating shaft 3, the rotating plate 32 is fixedly mounted on the top of the first rotating shaft 3 by locking two upper and lower lock nuts, the rotating plate 32 is symmetrically provided with first oblong holes 34 on both sides, two first test rods 33 are fixedly mounted in the first oblong holes 34 by locking two upper and lower lock nuts, a second oblong hole 12 is longitudinally provided on the top of the frame body 1, the bracket 4 is fixedly mounted in the second oblong hole 12 by a lock nut, the second test rod 41 is horizontally fixedly mounted on the bracket 4, the sliding sleeve 5 is fixedly mounted on the carrier plate 2, the second rotating shaft 51 is slidably mounted in the sliding sleeve 5, and the middle of the second rotating shaft 51 The second rotating shaft 51 is rotatably connected to the push plate 52 through a second ball bearing, the second rotating shaft 51 is fixedly connected to the rotating body of the second ball bearing, the retainer of the second ball bearing is fixedly installed on the push plate 52, the top of the guide rod 53 is fixedly connected to the push plate 52, the lower part of the guide rod 53 is slidably installed on the carrier plate 2, the top of the second rotating shaft 51 is set as a tool blind hole structure 8, the tool blind hole is composed of a lock nut 7 tool clamping hole and a screw rod 91 accommodating hole coaxially connected, the lock nut 7 is slidably installed up and down in the tool clamping hole, the bottom of the second rotating shaft 51 is fixedly installed with a handwheel 6, the handwheel 6 is located at the lower part of the carrier plate 2, and also includes a control module and an acoustic waveguide. Sound / light alarm device, the first test rod 33 and the second test rod 41 are both set as spring telescopic rod structures, and displacement sensors are set on the movable ends of the spring telescopic rods. The displacement sensor and the sound / light alarm device are respectively connected to the control module through circuits. The outer ends of the first test rod 33 and the second test rod 41 are in contact with the toilet cover. In order to reduce the friction between the contact ends of the first test rod 33 and the second test rod 41 and the toilet cover, balls are embedded in the outer ends of the first test rod 33 and the second test rod 41, and there is rolling friction between the balls and the toilet cover to extend the service life of the first test rod 33 and the second test rod 41.

[0015] It also includes a limit card 54, which can be mounted on the guide rod 53, and after the limit card 54 contacts the top surface of the carrier plate 2, the limit position of the downward movement of the guide rod 53 is limited. A pull ring is fixedly provided on the outer end of the limit card 54, which can be used to separate the limit card 54 from the guide rod 53, so that the guide rod 53 can move freely up and down.

[0016] The four corners of the bottom of the frame body 1 are screwed with support adjustment feet 11, and the support adjustment feet 11 are used to adjust the stability of the frame body 1.

[0017] The bottom surface of the top of the frame body 1 is provided with a receiving slot 13 that matches the top of the second rotating shaft 51. The entrance of the receiving slot 13 is arranged as an angled structure to increase the limit position of the upward movement of the second rotating shaft 51, thereby extending the depth of the tool clamping hole, and avoiding the problem that the lock nut 7 is located at the end of its tool clamping hole and thus falls out of it.

[0018] The smart toilet cover 9 is placed on the top of the frame body 1, and the bolt 91 of the smart toilet cover 9 passes through the mounting hole on the top of the frame body 1. The operator pushes the combination of the hand wheel 6, the second rotating shaft 51, the push plate 52, and the guide rod 53 to move upward under the guidance of the sliding sleeve 5. The lock nut 7 is placed in the tool blind hole structure 8 on the top of the second rotating shaft 51. The second rotating shaft 51 is rotated by the hand wheel 6 to rotate, and the lock nut 7 is screwed and installed on the bolt 91. After the lock nut 7 is tightened, the smart toilet cover 9 is fixedly installed on the top of the frame body 1, and the cover plate of the smart toilet cover 9 is started to reciprocate and open and close. The cover plate contacts the second test rod 41 to compress it, and the movable rod of the second test rod 41 and the displacement sensor send signals to the control module. By recording the signal sending time of the movable rod of the second test rod 41 and the displacement sensor, it can be detected whether the time period of the reciprocating opening and closing operation of the cover plate of the smart toilet cover 9 is always consistent, and the number of times the cover plate of the smart toilet cover 9 is opened and closed is counted. When the cover plate of the smart toilet cover 9 is opened and closed, The rotating plate 32 rotates to a longitudinal state to avoid interference with the cover plate of the smart toilet cover 9. When the cover plate of the smart toilet cover 9 is closed, the driving motor 31 drives the first rotating shaft 3, the rotating plate 32, and the first test rod 3 to rotate 360°. The two first test rods 3 are asymmetrically installed in the first oblong holes 34 on both sides of the rotating plate 32. The movable ends of the two first test rods 3 are crimped into contact with the outer surface of the cover plate of the smart toilet cover 9 under the action of elastic force. The outer surface of the cover plate of the smart toilet cover 9 is generally a planar structure or a curved structure with a high middle part. Therefore, the movable end of the first test rod 3 can always be elastically crimped into contact with the outer surface of the cover plate of the smart toilet cover 9. The position sensor on the movable end of the first test rod 3 sends a signal to the control module. The control module judges the closing flatness of the cover plate of the smart toilet cover 9 by comparing the signal curve of the position sensor on the subsequent active end of the first test rod 3 with the first signal curve, and then tests its closing stability and accuracy. In addition, in order to shorten the overall height of the rack body 1, the height space between the top of the rack body 1 and the carrier plate 2 is small, and it is difficult for the operator to reach out and use tools to lock and fix the lock nut and the bolt 91 of the smart toilet cover. Therefore, the hand wheel 6 for rotation is set in the area where the drive motor 31 is installed between the lower part of the rack body 1 and the carrier plate 2, so that the operator can rotate the second rotating shaft 51 and the lock nut 7 through the hand wheel 6.
