Abstract

This invention discloses a design method for an adjusting rod adapted to different adjusting sleeves, and an adjusting rod designed using this method. The design method includes the following steps: Step 1: Draw two types of teeth with different tooth spacing and tooth height on the rod bodies of two identical adjusting rods, forming two drawings; Step 2: Align and overlap the rod body portions of the two drawings to obtain the overlapping portion of the two adjusting rods; Step 3: Erase the non-overlapping portions of the two adjusting rods to obtain a new adjusting rod. The adjusting rod designed in this invention forms its external teeth by overlapping two types of teeth with the same rod body. The external teeth of the adjusting rod can be used with the adjusting sleeves adapted to the corresponding two types of teeth, allowing one adjusting rod to be adapted to two types of adjusting sleeves. The application scenarios of the adjusting rod are no longer limited, and its versatility is enhanced. The continuous arrangement of the external teeth on the rod body makes the relative adjustment range between the adjusting rod and the adjusting sleeve larger and more flexible.

Description

Technical Field

[0001] This invention relates to the field of in-wall water tank accessories, and in particular to a design method for an adjusting rod adapted to different adjusting sleeves, and an adjusting rod designed by the method. Background Technology

[0002] Wall-hung toilets are becoming increasingly popular due to their suspended installation on the wall, allowing for thorough cleaning and eliminating blind spots. Wall-hung toilets typically feature an in-wall cistern (also known as a concealed cistern). [See reference...] Figure 1 As shown, the drainage method of the wall-mounted water tank a is as follows: the user presses button c on the control panel b. Button c drives the adjusting rod e, which passes through the panel bracket d, to move axially. The adjusting rod e then drives the adjusting sleeve f connected to it to swing, thereby opening the drain valve inside the water tank a to drain the water and complete the flushing operation. The adjusting rod e engages with the adjusting sleeve f through interlocking teeth 3. When the adjusting rod e is driven by button c, it applies an axial force to the adjusting sleeve f, thus causing the adjusting sleeve f to swing. However, due to the installation position limitations of the control panel b and other accessories, the engagement between the adjusting rod e and the adjusting sleeve f cannot be too loose.

[0003] In existing technologies, adjusting rods and adjusting sleeves are usually manufactured by the same company. However, adjusting rods and sleeves from different manufacturers have their own sizes and specifications, meaning that an adjusting rod can typically only be used with adjusting sleeves from the same manufacturer, lacking universality. If the adjusting rod is damaged during use, the user's choice of adjusting sleeves is severely limited, resulting in a poor user experience. To solve the compatibility problem, some manufacturers use a segmented design on the same adjusting rod, setting two or more segments with different tooth spacing and heights on the circumference of the adjusting rod. Each segment can be used with a different adjusting sleeve. This method has significant drawbacks: the range of adjustment that a single adjusting sleeve can fit on the adjusting rod is limited, which restricts the installation depth of the adjusting rod inside the water tank. This makes it difficult to adapt the protrusion of the adjusting rod on the water tank surface to the installation position of accessories such as the control panel. In practical applications, segmented adjusting rods do not effectively solve the overall structural compatibility problem. Summary of the Invention

[0004] The purpose of this invention is to provide a design method for an adjusting rod that can adapt to different adjusting sleeves, and an adjusting rod designed by the method. The adjusting rod can adapt to two different sizes of adjusting sleeves, thus having higher versatility.

[0005] To achieve the above objectives, one solution of the present invention is:

[0006] A method for designing an adjusting rod that adapts to different adjusting sleeves includes the following steps:

[0007] Step 1: Draw two different tooth patterns with different tooth spacing and tooth height on the two identical adjustment rods to create two drawings;

[0008] Step 2: Align and overlap the rod sections on the two drawings to obtain the overlapping parts of the two adjusting rods;

[0009] Step 3: Erase the non-overlapping parts of the two adjusting rods to obtain new adjusting rods.

[0010] In step one, the range of the interdental distance ratio d for the two types of teeth is 0.2≤d≤5, and the range of the tooth height ratio h for the two types of teeth is 0.75≤d≤1.33.

[0011] In step one, the tooth shape includes one of triangle, rectangle, and trapezoid, and the two teeth used for overlapping have the same tooth shape.

[0012] The second solution of the present invention is: an adjusting rod designed according to the adjustment rod design method for adapting to different adjusting sleeves, wherein the external teeth of the rod body are formed by overlapping design of two adjusting rods with different tooth spacing and tooth height, and the external teeth are arranged continuously in the axial direction of the rod body.

[0013] The rod body has a clearance portion and a limiting portion that are rotatably engaged with the adjusting sleeve on its circumferential surface, and the external teeth are sequentially arranged on the surface of the limiting portion along the axial direction of the rod body.

[0014] After adopting the above technical solution, the present invention has the following technical effects:

[0015] ① The adjusting rod forms its outer teeth by overlapping two types of teeth with the same rod body. The outer teeth of the adjusting rod and the adjusting sleeves that are matched with the two types of teeth can be used together, so that one adjusting rod can be matched with two types of adjusting sleeves. The application scenarios of the adjusting rod are no longer limited, and its versatility is stronger.

[0016] ② The external teeth of the adjusting rod are arranged continuously along the axial direction of the adjusting rod body. The adjusting sleeve can be engaged and bite at any position on the rod body, which makes the adjusting rod more adjustable and more flexible in use during product assembly. Therefore, it can meet the assembly requirements of more wall-mounted water tanks. Attached Figure Description

[0053] Furthermore, this invention provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0054] refer to Figure 2 As shown, the present invention discloses an adjusting rod 1 adapted to different adjusting sleeves, including a rod body 11; the circumferential surface of the rod body 11 is provided with a clearance part 111 and a limiting part 112 that are rotatably engaged with the adjusting sleeve 2. The clearance part 111 is aligned with the internal teeth 21 of the adjusting sleeve 2 to achieve clearance when the rod body 11 moves axially, and the limiting part 112 is engaged with the internal teeth 21 of the adjusting sleeve 2 to achieve axial limiting after the rod body 11 rotates.

[0055] The surface of the limiting part 112 is provided with a plurality of external teeth 1121 arranged sequentially along the axial direction of the rod 11. These external teeth 1121 are the overlapping parts of two teeth with different tooth pitches and tooth heights. That is, two kinds of teeth are designed on the rod 11, and the tooth pitches or tooth heights of the two kinds of teeth are different, or the tooth pitches and tooth heights of the two kinds of teeth are both different. After the two kinds of teeth are arranged along the axial direction of the rod 11 on the surface of the limiting part 112, the non-overlapping parts are removed, and the remaining overlapping parts are the external teeth 1121 of the present invention (see the design method below for the specific method).

[0056] The following shows a specific embodiment of the adjusting rod.

[0057] The aforementioned external teeth 1121 and teeth are all annular teeth with a certain arc length set along the circumference of the rod 11; the tooth shape includes one of triangle, rectangle, and trapezoid, and the two tooth shapes used for overlapping design are the same. That is to say, when carrying out overlapping design, the combination of teeth is triangle + triangle, rectangle + rectangle, trapezoid + trapezoid.

[0058] The range of the tooth spacing ratio d for the two types of teeth is 0.2 ≤ d ≤ 5; simultaneously, the range of the tooth height ratio h for the two types of teeth is 0.75 ≤ d ≤ 1.33. Within this parameter range, the adjustment rod 1 and the adjustment sleeve 2 adapted to the two types of teeth fit closely, making operation convenient.

[0059] The aforementioned limiting parts 112 are arranged at equal angular intervals around the center line of the rod body 11, and a clearance part 111 is provided between adjacent limiting parts 112. Therefore, the directional restriction when assembling the adjusting rod 1 and the adjusting sleeve 2 can be reduced. The adjusting rod 1 can be inserted into the adjusting sleeve 2 simply by aligning the clearance part 111 with the inner tooth 21 of the adjusting sleeve 2.

[0060] The aforementioned clearance portion 111 is a recessed groove with a fan-shaped cross-section formed on the circumference of the rod body 11, corresponding to the shape of the inner teeth 21 of the adjusting sleeve 2.

[0061] The present invention also includes a rod cap 12; the rod cap 12 is integrally connected to the end of the rod body 11, and a plurality of protrusions 121 are provided on its circumferential surface. For example, in this embodiment, the protrusions 121 are flanges provided along the axial direction of the rod body 11, which makes it convenient for the user to grip and turn the adjusting rod 1.

[0062] refer to Figure 3 and Figure 4 As shown, when the adjusting rod 1 and the adjusting sleeve 2 are assembled, the relief part 111 (that is, the groove mentioned above) of the adjusting rod 1 is aligned with the inner tooth 21 of the adjusting sleeve 2, and then the adjusting rod 1 is inserted into the adjusting sleeve 2 to the appropriate position. Then the adjusting rod 1 is rotated so that the outer tooth 1121 of the adjusting rod 1 engages with the inner tooth 21 of the adjusting sleeve 2.

[0063] refer to Figures 5 to 8 As shown, taking two types of adjusting sleeves 2a and 2b with the same tooth height and tooth spacing of 1.31 and 1.61 respectively as examples, and the external tooth 1121 on the adjusting rod 1 is the overlapping part of the two triangular teeth with tooth spacing of 1.31 and 1.61, by... Figure 6 and Figure 8 As can be seen from the two enlarged views, the adjusting rod 1 can engage with the adjusting sleeves 2a and 2b in some positions. When the adjusting rod 1 is pushed, it can drive the adjusting sleeves 2a and 2b to move, thereby realizing the function of the drain valve to drain water.

[0064] refer to Figures 9 to 12 As shown, taking two types of adjusting sleeves 2c and 2d with the same tooth height and tooth spacing of 2.62 and 3.22 respectively as examples, and the external tooth 1121 on the adjusting rod 1 is the overlapping part of the two rectangular teeth with tooth spacing of 2.62 and 3.22, by... Figure 10 and Figure 12 As can be seen from the two enlarged images, the adjusting rod 1 can engage with the adjusting sleeves 2c and 2d in some positions. When the adjusting rod 1 is pushed, it can drive the adjusting sleeves 2c and 2d to move, thereby realizing the function of the drain valve to drain water.

[0065] refer to Figures 13 to 16 As shown, taking two types of adjusting sleeves 2c and 2d with the same tooth height and tooth spacing of 2.62 and 3.22 respectively as examples, and the external tooth 1121 on the adjusting rod 1 is the overlapping part of the two trapezoidal teeth with tooth spacing of 2.62 and 3.22, by... Figure 14 and Figure 16 As can be seen from the two enlarged images, the adjusting rod 1 can engage with the adjusting sleeves 2c and 2d in some positions. When the adjusting rod 1 is pushed, it can drive the adjusting sleeves 2c and 2d to move, thereby realizing the function of the drain valve to drain water.

[0066] refer to Figures 17 to 20 As shown, the present invention also discloses a design method for an adjusting rod adapted to different adjusting sleeves, comprising the following steps:

[0067] Step 1: Draw two types of teeth 3 and 3' with different tooth pitch and tooth height on the rod body 11 of the two identical adjustment rods 1 respectively, forming two drawings;

[0068] Step 2: Align and overlap the rod 11 parts on the two drawings to obtain the overlapping parts of the two adjusting rods 1;

[0069] Step 3: Align the non-overlapping parts of the two adjusting rods (refer to...) Figure 18 Erase the shaded area to get a new adjustment lever.

[0070] The following illustrates a specific embodiment of the design method.

[0071] The above design method can be implemented using computer-aided design (CAD) to mainly draw the cross-section of the adjusting rod.

[0072] The range of the tooth spacing ratio d for the two types of teeth 3 is 0.2 ≤ d ≤ 5; simultaneously, the range of the tooth height ratio h for the two types of teeth 3 is 0.75 ≤ d ≤ 1.33. Within this parameter range, the adjustment rod 1 and the adjustment sleeve 2 adapted to the two types of teeth 3 fit together tightly, making operation convenient.

[0073] In step one, the tooth shape of the aforementioned teeth includes one of triangle, rectangle, and trapezoid, and the tooth shape of the two teeth used for overlapping is the same.

[0074] The product obtained by the above design method, namely the rod body 11 of the adjusting rod 1, has external teeth 1121 formed by the overlapping design of two adjusting rods with different tooth pitch and tooth height. The external teeth 1121 are arranged continuously in the axial direction of the rod body 11.

[0075] Through the above scheme, the design method and the designed adjusting rod 1 form its external teeth 1121 by overlapping two types of teeth 3 with the same rod body 11. The external teeth 1121 of the adjusting rod 1 and the adjusting sleeves 2 adapted to the corresponding two types of teeth 3 can be used together, so that one adjusting rod 1 can be adapted to two types of adjusting sleeves 2. The application scenarios of the adjusting rod 1 are no longer limited, and its versatility is stronger. The external teeth 1121 of the adjusting rod 1 are arranged continuously in the axial direction of the rod body 11 of the adjusting rod 1. The adjusting sleeves 2 can be engaged and bite at any position on the rod body 11, so that the adjusting rod 1 can be adjusted within a larger range and used more flexibly during product assembly. Therefore, it can meet the assembly requirements of more wall-mounted water tanks.

[0076] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
