Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic products, specifically to a tool for checking the left-right symmetry of a toilet mounting surface. Background Technology
[0002] Currently, the symmetry of the toilet's base mounting surface is tested using traditional manual methods. The process involves placing the toilet upright and then having a worker visually inspect it, relying on personal experience and subjective judgment. This method has significant drawbacks. It relies excessively on subjective human judgment, lacks objective quantitative standards, and prolonged work can lead to worker fatigue, resulting in decreased accuracy, a significantly increased risk of misjudgment, and difficulty in ensuring the stability and reliability of the tested product quality. Utility Model Content
[0003] Based on this, and in response to the above problems, this utility model provides a tool for checking the left-right symmetry of the toilet mounting surface.
[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] A tool for checking the left-right symmetry of a toilet mounting surface includes a transparent panel for contacting the toilet mounting surface, a pair of left-right distributing blocks on the back of the transparent panel, and a drive mechanism for driving the two blocks to move synchronously in opposite directions against the inner wall of the mounting opening of the toilet mounting surface, so that the center position of the transparent panel coincides with the center position of the toilet mounting surface. The transparent panel has scale lines for measurement and scale values.
[0006] Using the above technical solution, during inspection, the toilet is first erected, with the back of the transparent panel in contact with the toilet's mounting surface. Then, a drive mechanism activates two locking blocks that press against the mounting openings on the toilet's mounting surface, aligning the center of the transparent panel with the center of the toilet's mounting surface. The inspection is then performed using the scale lines and values on the transparent panel, thus avoiding errors caused by subjective human judgment and accurately measuring symmetry, improving the accuracy and reliability of the inspection results. Furthermore, this inspection tool is convenient and simple to use, replacing the process of repeated manual adjustments and visual inspection, reducing labor intensity, and is suitable for inspecting toilets of various sizes.
[0007] In a specific embodiment of this utility model: the driving mechanism includes an open outer shell on the left and right sides, and a rotatable gear installed inside the outer shell. Two racks are symmetrically arranged on the upper and lower sides of the gear, and both racks mesh with the gear. Two locking blocks are respectively fixed on the outer ends of the corresponding racks. Each rack is slidably installed inside the outer shell through a mounting structure.
[0008] In a specific embodiment of this utility model: the mounting structure includes multiple bolts, the rack has a horizontally arranged groove, the outer shell has multiple first bolt holes corresponding to the position of the groove, the transparent panel has second bolt holes that correspond one-to-one with the number and position of the first bolt holes, and the end of each bolt passes through the corresponding first bolt hole, through the groove, and is tightened in the corresponding second bolt hole.
[0009] In a specific embodiment of this utility model: a rotating wheel connected to the gear and used to drive the gear to rotate is also installed on the front of the transparent panel.
[0010] In a specific embodiment of this utility model: the transparent panel is made of acrylic sheet. Using acrylic sheet not only provides high light transmittance, allowing the toilet mounting surface to be clearly seen through the panel for convenient subsequent inspection, but it is also lightweight, wear-resistant, and not easily damaged.
[0011] In a specific embodiment of this utility model: a handle is provided on the upper part of the front of the transparent panel. With this structure, the operator can stably control the movement direction of the transparent panel by holding the handle, especially improving operational controllability when aligning the toilet mounting surface with the center of the panel.
[0012] In summary, during inspection, the toilet is first erected. After the back of the transparent panel contacts the toilet's mounting surface, the drive mechanism moves two locking blocks against the mounting opening on the toilet's mounting surface, aligning the center of the transparent panel with the center of the toilet's mounting surface. The scale lines and values on the transparent panel are then used for inspection, thus avoiding errors caused by subjective human judgment. This allows for precise measurement of symmetry, improving the accuracy and reliability of the test results. Furthermore, this inspection tool is convenient and simple to use, replacing the process of repeated manual adjustments and visual inspection, reducing labor intensity, and is suitable for inspecting toilets of various sizes.

[0018] 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.
[0019] Please see Figure 1 , Figure 2 and Figure 4 As shown, this utility model is a tool for checking the left and right symmetry of a toilet mounting surface, including a transparent panel 10 for contacting the toilet mounting surface 9, a pair of left and right distributed locking blocks 11 on the back of the transparent panel 10, and a driving mechanism 20 for driving the two locking blocks 11 to move back and forth against the mounting opening 8 of the toilet mounting surface 9 so that the middle position of the transparent panel coincides with the middle position of the toilet mounting surface 9.
[0020] The transparent panel 10 has scale lines for measurement and scale values. To better illustrate this embodiment, multiple horizontal and vertical dashed lines are used to represent the scale lines and scale values on the panel.
[0021] When performing a toilet mounting surface symmetry test, the toilet is first placed upright so that the back of the transparent panel 10 of the inspection tool is completely in contact with the toilet mounting surface 9. A drive mechanism then drives two locking blocks to move synchronously back-to-back until the blocks abut against the inner wall of the mounting opening 8 on the toilet mounting surface 9, aligning the center of the toilet mounting surface 9 with the center of the transparent panel 10. Using the scale lines and values on the transparent panel 10, inspectors can quickly and accurately measure the symmetry of the toilet mounting surface 9, effectively avoiding measurement errors caused by subjective human judgment and meeting the inspection needs of various toilet sizes.
[0022] like Figure 2 and Figure 3 As shown, in this embodiment, the drive mechanism 20 includes a housing 21 with openings on the left and right sides, and a rotatable gear 22 installed inside the housing 21. Two racks 23 are symmetrically arranged on the upper and lower sides of the gear 22 inside the housing 21. Both racks 23 mesh with the gear 22. Two locking blocks 11 are respectively fixed to the outer ends of the corresponding racks 23. Each rack 23 is slidably installed inside the housing 21 via a mounting structure.
[0023] In this embodiment, the mounting structure includes two bolts 24. The rack 23 has a horizontally arranged groove 25. Two first bolt holes 26 are distributed on the outer casing 21 corresponding to the groove 25. The transparent panel 10 has second bolt holes that correspond one-to-one in number and position to the first bolt holes 26. During assembly, the ends of each bolt 24 pass through the corresponding first bolt hole 26, through the groove 25, and are tightened into the corresponding second bolt hole.
[0024] Additionally, a rotating wheel 28 connected to the gear 22 is installed on the front of the transparent panel 10 to drive the gear 22 to rotate. In this way, by rotating the rotating wheel 28 clockwise or counterclockwise, the gear 22 is driven to rotate, which in turn drives the two racks to move towards or away from each other with the locking blocks.
[0025] In this embodiment, the transparent panel 10 is made of acrylic sheet. Using acrylic sheet not only provides high light transmittance, allowing the toilet mounting surface to be clearly seen through the panel for easy subsequent inspection, but it is also lightweight, wear-resistant, and not easily damaged.
[0026] In this embodiment, a handle 13 is provided on the upper part of the front of the transparent panel 10. In this way, the operator can hold the handle to stably control the movement direction of the transparent panel, which improves the controllability of operation, especially when aligning the toilet mounting surface with the middle position of the panel.
[0027] The above describes a tool for checking the left-right symmetry of a toilet mounting surface according to this utility model. During inspection, the toilet is first placed vertically so that the back of the transparent panel 10 of the tool is completely flush with the toilet mounting surface 9. Then, the rotating wheel is turned, causing the gears to rotate and driving the two racks 23 to move the locking blocks 11 backwards until the locking blocks 11 abut against the inner wall of the mounting opening 8 of the toilet mounting surface 9, so that the center position of the transparent panel coincides with the center position of the toilet mounting surface. Finally, using the scale lines and values on the transparent panel 10, the symmetry of the toilet mounting surface is quickly and accurately measured.
[0028] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
