Description

Technical Field

[0001] The utility model relates to the technical field of ceramic valve cores, in particular to a ceramic valve core positioning piece. Background Art

[0002] The ceramic valve core is a component in the faucet and is a controller for controlling the water flow of the faucet. It controls the introduction and closing of the water flow by rotating the ceramic valve core. Before installing the ceramic valve core inside the faucet, a positioning piece must be installed at the bottom of the ceramic valve core. The positioning piece can be used to assist in positioning the installation of the ceramic valve core to ensure that the water hole at the bottom of the ceramic valve core can correspond exactly to the water hole inside the faucet. For example, patent No. CN202122331866.9 discloses a ceramic valve core positioning piece. This solution realizes the connection and fixation between it and the valve core by providing a mounting structure on the positioning piece body. The mounting structure mainly consists of a reset spring, a fixing block and a fixing groove. When in use, the positioning piece is adapted to the bottom of the valve core. At this time, the fixing block is in a closed state. Then the positioning piece is rotated so that the position of the fixing block corresponds to the position of the fixing groove, and resets under the action of the reset spring so that the fixing block closes to the fixing groove, thereby realizing the connection between the positioning piece and the valve core. However, this solution has certain defects and shortcomings when used:

[0003] First, when assembling the valve core and the positioning piece in this way, the fixing block is pressed against the fixing groove by means of a return spring, and this fixing method is not stable enough. The fixing block may easily fall off during use, resulting in an unstable connection between the positioning piece and the valve core. Secondly, although this method can achieve the connection between the positioning piece and the valve core, it is not convenient for disassembly between the valve core and the positioning piece, and then it is not convenient for inspection and maintenance of the components, and the convenience of use is poor, so it needs to be improved.

The extension section 102 is provided with a plurality of coarse holes 103 distributed in an array, and the extension section 102 is provided with a fine hole 105 on one side of the coarse hole 103, and the fine hole 105 penetrates the inner side of the positioning piece body 1; a fixing structure 2 is provided with a plurality of , and multiple fixing structures 2 are installed at the coarse hole 103 and fine hole 105 corresponding to the extension section 102. The fixing structure 2 includes a telescopic shaft 201 and a positioning shaft 203 coaxially arranged on one side of the telescopic shaft 201, wherein the telescopic shaft 201 is slidably connected to the coarse hole 103 of the extension section 102, and the positioning shaft 203 slides at the fine hole 105, and a positioning protrusion 204 is integrally formed on the end of the positioning shaft 203 away from the telescopic shaft 201, and the positioning protrusion 204 is adapted to the positioning hole 6 corresponding to the valve core body 3.

[0026] It should be noted that, by setting the positioning piece body 1 as three parts, namely, a circular positioning plate 101, an extension section 102 and an annular positioning plate 106, wherein the circular positioning plate 101 is the main part of the positioning piece body 1, and the contour of the extension section 102 is a conical design, the setting of the annular positioning plate 106 can achieve the initial adaptation between the valve core body 3 and the positioning piece body 1, and by setting a coarse hole 103 and a fine hole 105 at the extension section 102, the adaptation installation of the fixed structure 2 is satisfied, and the fixed structure 2 is composed of a telescopic shaft 201 adapted to the coarse hole 103, and a positioning shaft 203 adapted to the fine hole 105. The telescopic shaft 201 is coaxially connected and fixed with the positioning shaft 203, so that the telescopic shaft 201 and the positioning shaft 203 can be telescoped synchronously. By setting a positioning protrusion 204 at the end of the positioning shaft 203, the positioning shaft 203 and the positioning protrusion 204 are adapted to the corresponding positioning hole 6 on the valve core body 3. When the telescopic shaft 201 and the positioning shaft 203 move toward the center of the positioning piece body 1, the positioning shaft 203 and the positioning protrusion 204 can be closed to the positioning hole 6 of the valve core body 3, thereby realizing the assembly and fixation between the positioning piece body 1 and the valve core body 3. This method of fixation is stable and prevents the structures from falling off.

[0027] like Figure 1 and Figure 3 As shown, in some embodiments, a limiting groove 104 is provided on the inner wall of the annular positioning plate 106 , and a limiting block 4 is provided on the outer wall of the valve core body 3 , and the limiting block 4 is adapted to the limiting groove 104 .

[0028] It should be noted that the setting of the limit block 4 and the limit groove 104 can realize the limiting function when the positioning piece body 1 is assembled on the valve core body 3, so that the positioning hole 6 is aligned with the fine hole 105, thereby realizing the fixing function of the fixing structure 2 on the valve core body 3.

[0029] like Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, a spring 202 is sleeved on the positioning shaft 203 , and two ends of the spring 202 are respectively connected and fixed to the telescopic shaft 201 and the extension section 102 .

[0030] It should be noted that the setting of the spring 202 can realize the automatic elastic extension of the telescopic shaft 201 and the positioning shaft 203, realize the automatic reset of the positioning shaft 203 and the positioning protrusion 204, and cancel the fixing effect of the positioning piece body 1 on the valve core body 3.

[0032] It should be noted that the annular body 501 is threadedly connected to the outer wall of the annular positioning plate 106, so that the annular body 501 can be raised and lowered along the annular positioning plate 106. By setting a beveled surface 502 at the bottom of the annular body 501 and setting an arc-shaped protrusion 205 at the end of the telescopic shaft 201, when the annular body 501 rotates and moves downward, the beveled surface 502 at its bottom can offset the arc-shaped protrusion 205, thereby realizing the telescopic control of the telescopic shaft 201 and the positioning shaft 203, and then the positioning shaft 203 and the positioning protrusion 204 are closed to the positioning hole 6 of the valve core body 3, thereby realizing the installation and positioning of the positioning piece body 1 on the valve core body 3. When the limit ring 5 is rotated in the opposite direction, the beveled surface 502 at the bottom of the limit ring 5 can leave the arc-shaped protrusion 205, and then the telescopic shaft 201 and the positioning shaft 203 are reset under the action of the spring 202, thereby canceling the installation and fixation of the positioning piece body 1 on the valve core body 3.

[0033] like Figure 3 and Figure 4 As shown, in some embodiments, a through hole is provided on the circular positioning plate 101 of the positioning piece body 1 .
