The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0037] Existing plastic valve stems are inexpensive but have limited strength; all-copper valve stems have high strength but are too expensive; if the valve core stem is made of both copper and plastic, the wall thickness of the two materials will be reduced, which will actually decrease the strength.
[0038] like Figures 1 to 5 As shown, some embodiments of this utility model provide a valve core rod, which has a first direction and a second direction that are perpendicular to each other. This valve core rod is mainly used in valve cores to improve the strength and stability of the valve core rod body during use.
[0039] The valve core rod includes a protruding rod 100, a rod cap 200, and a connector 300. It should be noted that in this embodiment, the protruding rod 100 is a metal rod, and the rod cap 200 is a plastic rod cap 200.
[0040] The protruding rod 100 includes a first rod body 110 and a second rod body 120, which are connected to define a first step 130. The connection method between the first rod body 110 and the second rod body 120 includes snap-fit, bonding, welding, threaded connection or integral molding, which can be specifically set according to the actual situation.
[0041] It is understood that the outer diameter of the first rod 110 is smaller than the outer diameter of the second rod 120, so as to form the first step 130 between the first rod 110 and the second rod 120.
[0042] It should be noted that, in this embodiment, the first rod 110 and the second rod 120 are integrally formed to form the protruding rod 100. The axis of the first rod 110 and the axis of the second rod 120 coincide with the axis of the protruding rod 100.
[0043] The protruding rod 100 provided in this application is made of metal material, such as copper rod, iron rod, stainless steel rod or alloy rod.
[0044] In this embodiment, the protruding rod 100 is a copper rod. It should be noted that copper rods have good corrosion resistance and oxidation resistance, and can maintain good adaptability in complex environments such as high temperature and high humidity, acid and alkaline environments; in addition, copper rods can be easily processed into various shapes through processing techniques such as deformation, shearing, and bending to meet different needs.
[0045] In addition, the first rod body 110 is provided with a first connecting hole 111 and a second connecting hole 112 spaced apart, and the first connecting hole 111 and the second connecting hole 112 respectively penetrate the first rod body 110 along the first direction. It can be understood that the axis of the first connecting hole 111 and the axis of the second connecting hole 112 are perpendicular to the axis of the first rod body 110.
[0046] Along the second direction, a first mounting groove 210 is provided on one side of the rod cap 200. The rod cap 200 is sleeved on the first rod body 110. The groove wall of the first mounting groove 210 abuts against the outer wall of the first rod body 110 to form a limiting structure to prevent the rod cap 200 from rotating relative to the first rod body 110, thereby improving the compactness and stability of the connection between the rod cap 200 and the protruding rod 100.
[0047] In addition, the pole cap 200 is abutted against the first step 130 so that the first step 130 can limit the pole cap 200, thereby ensuring the accuracy of the connection position between the pole cap 200 and the pole body and the installation efficiency.
[0048] The connector 300 fills the first connecting hole 111 and the second connecting hole 112, and connects the protruding rod 100 and the rod cap 200 through the connector 300. This not only improves the stability of the connection between the protruding rod 100 and the rod cap 200, but also further improves the compactness of the connection between the rod cap 200 and the protruding rod 100, and improves the strength of the rod cap 200 and the overall strength of the valve core rod.
[0049] It should be noted that the connector 300 is a hot melt component. The connector 300 is injection molded into the first connecting hole 111 and the second connecting hole 112, and the protruding rod 100 and the rod cap 200 are formed in one step to improve the overall strength and stability of the valve core rod.
[0050] This invention combines a copper rod and a plastic rod cap, and through a reasonable copper-plastic ratio and structural adjustments, it not only controls costs effectively but also ensures optimal valve core strength.
[0051] like Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the first rod 110 has a first wall surface 113 and a second wall surface 114 disposed opposite to each other along the first direction, and the first mounting groove 210 has a third wall surface 211 and a fourth wall surface 212 disposed opposite to each other. The first wall surface 113 abuts against the third wall surface 211, and the second wall surface 114 abuts against the fourth wall surface 212. The first wall surface 113, the second wall surface 114, the third wall surface 211, and the fourth wall surface 212 are parallel to each other. It can be understood that the first rod 110 has a flat structure, so that the outer wall of the first rod 110 can connect with the groove wall of the first mounting groove 210 to form a limiting structure, preventing the rod cap 200 from rotating relative to the first rod 110 and ensuring the stability of the connection between the rod cap 200 and the first rod 110.
[0052] like Figure 5As shown, in some embodiments of this utility model, the rod cap 200 has a second mounting groove 220 communicating with the first mounting groove 210 on the side facing the second rod body 120. The inner diameter of the second mounting groove 220 is larger than the inner diameter of the first mounting groove 210, so that the groove wall of the second mounting groove 220 and the groove wall of the first mounting groove 210 define a second step 230. The second step 230 abuts against the first step 130, so that the second step 230 provides a limiting effect on the rod cap 200, thereby ensuring the accuracy of the installation position between the rod cap 200 and the rod body, improving production efficiency, and ensuring production quality.
[0053] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the end of the second rod 120 adjacent to the first rod 110 is at least partially housed in the second mounting groove 220, and the groove wall of the second mounting groove 220 abuts against the outer wall of the second rod 120, so as to form a limiting structure by connecting the groove wall of the second mounting groove 220 and the outer wall of the second rod 120, thereby further improving the compactness and stability of the connection between the rod cap 200 and the rod.
[0054] It should be noted that if the distance between the axis of the first connecting hole 111 and the axis of the second connecting hole 112 is too small, that is, if the distance between the first connecting hole 111 and the second connecting hole 112 is too small, the difference between the local strength of the first rod 110 and the strength of other areas will be too large, which will cause the local area of the first rod 110 to be prone to breakage under the action of external force; if the distance between the axis of the first connecting hole 111 and the axis of the second connecting hole 112 is too large, it will cause the strength of the two ends of the first rod 110 along the second direction to decrease.
[0055] Based on this, such as Figure 5 As shown, in some embodiments of this utility model, the first connecting hole 111 has a first axis 115 parallel to the first direction, and the second connecting hole 112 has a second axis 116 parallel to the first direction, so as to improve the convenience of injecting the connector 300 into the first connecting hole 111 and the second connecting hole 112, simplify the processing difficulty of the valve core rod, and improve the processing efficiency of the valve core rod.
[0056] Along the second direction, the distance between the first axis 115 and the second axis 116 is L1, and the length of the first rod 110 is L2. The ratio between L1 and L2 is m, where m satisfies 0.4 ≤ m ≤ 0.6. It can be understood that the value of the ratio m between L1 and L2 can be in the range of 0.4 ≤ m ≤ 0.6 or 0.5 ≤ m ≤ 0.6.
[0057] In this embodiment, by controlling the distance between the first axis 115 and the second axis 116, the strength difference between different regions of the first rod 110 is reduced, thereby ensuring the stability of the local strength of the first rod 110 and ensuring the uniformity of the force on different regions of the first rod 110.
[0058] It should be noted that if the diameters of the first connecting hole 111 and the second connecting hole 112 are too small, the filling amount of the connector 300 in the first connecting hole 111 and the second connecting hole 112 will be reduced, resulting in a decrease in the strength and stability of the connection between the rod body and the rod cap 200, making the rod cap 200 easy to fall off the rod body; if the diameters of the first connecting hole 111 and the second connecting hole 112 are too large, it will lead to a decrease in the overall strength of the first rod body 110, making the first rod body 110 easy to break under the action of external force.
[0059] Based on this, such as Figure 3 As shown, in some embodiments of this utility model, the diameter of the first connecting hole 111 is D1, the diameter of the second connecting hole 112 is D2, and the outer diameter of the first rod 110 is D3.
[0060] The ratio between D1 and D3 satisfies 0.4 ≤ D1 / D3 ≤ 0.7, and the ratio between D2 and D3 satisfies 0.4 ≤ D2 / D3 ≤ 0.7. It can be understood that the ratio between D1 and D3 can be any range from 0.4 ≤ D1 / D3 ≤ 0.7, 0.5 ≤ D1 / D3 ≤ 0.7, to 0.6 ≤ D1 / D3 ≤ 0.7, and can be specifically set according to the actual situation. Similarly, the ratio between D2 and D3 can be any range from 0.4 ≤ D2 / D3 ≤ 0.7, 0.5 ≤ D2 / D3 ≤ 0.7, to 0.6 ≤ D2 / D3 ≤ 0.7, and can be specifically set according to the actual situation.
[0061] In this embodiment, the diameter of the first connecting hole 111 is equal to the diameter of the second connecting hole 112 to ensure the uniformity of the force on the first rod 110.
[0062] In addition, by controlling the apertures of the first connecting hole 111 and the second connecting hole 112, the overall strength of the first rod body 110 is ensured while the filling amount of the connector 300 in the first connecting hole 111 and the second connecting hole 112 is increased, thereby improving the stability and connection strength of the connection between the rod cap 200 and the rod body, and effectively improving the strength of the rod cap 200.
[0063] It should be noted that, since the distance between the first wall surface 113 and the second wall surface 114 is smaller than the outer diameter of the first rod 110, if the distance between the first wall surface 113 and the second wall surface 114 is too small, the bending strength of the first rod 110 will be reduced, making the first rod 110 easily damaged under the action of external force; if the distance between the first wall surface 113 and the second wall surface 114 is too large, the thickness of the rod cap 200 will be reduced, the overall strength of the rod cap 200 will be reduced, making the rod cap 200 easily damaged under the action of external force.
[0064] Based on this, such as Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the distance between the first wall surface 113 and the second wall surface 114 along the first direction is h. The ratio between h and D3 satisfies 0.5 ≤ h / D3 ≤ 0.7.
[0065] It is understood that the ratio between the distance h and D3 between the first wall surface 113 and the second wall surface 114 can be 0.5≤h / D3≤0.7 or 0.6≤h / D3≤0.7, and can be set according to the actual situation.
[0066] In this embodiment, by controlling the distance between the first wall surface 113 and the second wall surface 114, the overall strength of the first rod body 110 is ensured while the thickness and strength of the rod cap 200 are increased, thereby improving the stability of the connection between the rod body and the rod cap 200 and thus increasing the strength of the valve core rod.
[0067] In addition, in some embodiments of this utility model, the ratio between the outer diameter of the protruding rod 100 and the outer diameter of the rod cap 200 is n, where n satisfies 0.5≤n≤0.9.
[0068] It is understood that the ratio n between the outer diameter of the protruding rod 100 and the outer diameter of the rod cap 200 can be any range of 0.5≤n≤0.9, 0.6≤n≤0.9, 0.7≤n≤0.9, or 0.8≤n≤0.9, and can be specifically set according to the actual situation.
[0069] By controlling the ratio between the outer diameter of the convex rod 100 and the outer diameter of the rod cap 200, the strength of the convex rod 100 and the rod cap 200 can be guaranteed, thereby improving the overall strength of the valve core rod.
[0070] like Figures 1 to 5 As shown, in some embodiments of this utility model, the second rod 120 has a protrusion 121 at one end opposite to the first rod 110. The protrusion 121 is used to rotatably connect with the valve core, thereby rotatably connecting the valve core rod with the valve core.
[0071] The second rod 120 has a through hole 122 at one end near the protrusion 121. The through hole 122 passes through the second rod 120 along the first direction, so that the connecting post can pass through the through hole 122 and connect with the valve core, thereby rotatably connecting the valve core rod and the valve core to ensure the stability of the valve core rod on the valve core.
[0072] In addition, such as Figure 6 As shown, some embodiments of this utility model provide a valve core, including a valve core body 400 and a valve core rod as described in any of the above embodiments. The end of the rod away from the rod cap 200 is rotatably connected to the valve core body 400, thereby rotatably connecting the valve core rod to the valve core body 400.
[0073] It is understood that the valve core has the structure and beneficial effects of the valve core rod described in any of the above embodiments, which will not be repeated here.
[0074] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.
[0075] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0076] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
