[0028] Schematic diagram of a gas stove valve stem that is easy to disassemble and assemble.

[0029] refer to Figures 1 to 3 According to any preferred embodiment of the utility model, a valve stem for a gas stove that is easy to disassemble and assemble is connected to a gas stove valve core, one end of the gas stove valve core has two grooves, and the valve stem for a gas stove that is easy to disassemble and assemble includes a rod body 10 and two external fasteners 20.

[0030] Specifically, in any embodiment of the present utility model, if Figure 1 and Figure 2 As shown, one end of the rod body 10 has two protrusions 101, each of the external fasteners 20 has a through hole 201 with an opening 202, each of the protrusions 101 is sleeved with an external fastener 20, and the protrusions 101 pass through the through hole 201, the material of the external fastener 20 is plastic, and the external fastener 20 is interference fit with the groove on the gas stove valve core, so when the rod body 10 rotates circumferentially, the gas stove valve core follows the circumferential rotation.

[0031] It should be noted that the width of the protrusion 101 is greater than the width of the opening 202 of the through hole 201. When the protrusion 101 passes through the through hole 201, the parts of the external fastener 20 located on both sides of the opening 202 are elastically deformed in the form of opposite movements, and the protrusion 101 passes through the through hole 201. After the protrusion 101 is placed in the through hole 201, the parts of the external fastener 20 located on both sides of the opening 202 restore the elastic deformation before the deformation. state, and prevent the protrusion 101 from being separated from the external fastener 20; it should be emphasized that by sleeved on the protrusion 101, and the material of the external fastener 20 is plastic, when the assembler presses the protrusion 101 sleeved with the external fastener 20 into the groove, although the external fastener 20 and the groove have an interference fit, the assembler can more easily press the protrusion 101 sleeved with the external fastener 20 into the groove because plastic is easier to deform than metal. In the groove; and in taking out the valve stem for the gas stove that is easy to disassemble and assemble, it is only necessary to make the protrusion 101 of the rod body 10 slip out of the opening 202 of the external fastener 20. Since the material of the external fastener 20 is plastic, although the width of the opening 202 is smaller than the width of the protrusion 101, after the rod body 10 is subjected to an upward pulling force, the parts of the external fastener 20 located on both sides of the opening 202 move away from each other to take out the rod body 10. Compared with the prior art, the protrusion 101 and the valve core are both metal, and it is not easy to press the protrusion 101 into the groove when the two are interference fit, and it is not easy to take the protrusion 101 out of the groove when taking it out. The embodiment of the present application has the advantage of less effort during disassembly and assembly; in addition, since the material of the valve core is metal and the material of the external fastener 20 is plastic, even if the size error of the external fastener 20 is slightly larger, it can be squeezed into the groove, thereby achieving the advantage of lower processing accuracy requirements.

[0032] Furthermore, in order to facilitate the protrusion 101 to be disengaged from the opening 202, the portions of the external fastener 20 located on both sides of the opening 202 are easily deformed. Figure 2 As shown, the outer fastener 20 includes two curved portions 203 , the two curved portions 203 are respectively located at two sides of the opening 202 , and the distance between the two curved portions 203 gradually decreases from one end to the other end.

[0033] Further, in the first embodiment of the present utility model, as Figure 2 As shown, the external fastener 20 also includes a semicircular portion 204, the two ends of which are respectively connected to the two curved portions 203, the maximum radial dimension of the semicircular portion 204 is greater than the minimum spacing between the two curved portions 203, and a cross-section of the protrusion 101 is circular.

[0034] It should be noted that in the first embodiment, when the protrusion 101 with the external fastener 20 is placed in the groove, the two ends of the semicircular portion 204 are in line contact with the side wall of the groove. Since the semicircular portion 204 has an arc, the external fastener 20 is easy to be pressed into the groove.

[0035] Figure 3 The diagram shows a second embodiment of the utility model. In the second embodiment, the external fastener 20 also includes a U-shaped portion 205, and the two ends of the U-shaped portion 205 are respectively connected to the two curved portions 203. The width of the U-shaped portion 205 is greater than the minimum spacing between the two curved portions 203, and a cross-section of the protrusion 101 is arch-shaped.

[0036] It should be noted that, compared with the first embodiment, in the second embodiment, the contact between the protrusion 101 and the groove is surface contact, and the contact area is larger.

[0037] Furthermore, in the second embodiment, if Figure 3 As shown, in order to facilitate the protrusion 101 to pass through the opening 202, the bottom of the protrusion 101 has two first guiding slopes 1011. When the protrusion 101 passes through the opening 202, the first guiding slopes 1011 abut against the parts of the external fastener 20 located on both sides of the opening 202.

[0038] Furthermore, in the second embodiment, if Figure 3 As shown, in order to facilitate the U-shaped portion 205 to extend into the groove, one end of the U-shaped portion 205 away from the curved portion 203 has two second guiding inclined surfaces 2051 .

[0039] Furthermore, in any embodiment of the present utility model, in order to prevent the outer fastener 20 from rotating circumferentially relative to the protrusion 101, as shown in FIG. Figure 2 As shown, the through hole 201 has an anti-rotation groove 2011 on one side away from the opening 202, and the central plane of the anti-rotation groove 2011 coincides with the central axis of the through hole 201. One end of each of the protrusions 101 has an extension portion 1012, and when the protrusion 101 is placed in the through hole 201, the extension portion 1012 is placed in the anti-rotation groove 2011.

[0040] Furthermore, in order to facilitate the screw connection between the rod body 10 and the outside, as Figure 1 As shown, the end of the rod body 10 away from the protrusion 101 has a cut surface 102, and the cross-section of the end of the rod body 10 away from the protrusion 101 is non-circular; in addition, the end of the rod body 10 away from the protrusion 101 has a retaining ring groove 103.

[0041] In summary, the easily disassembled gas stove valve stem according to the embodiment of the present application is explained, which provides the easily disassembled gas stove valve stem with advantages such as less effort during disassembly and assembly and lower processing precision requirements.
