Description

Technical Field

[0001] The utility model belongs to the field of handheld ignition tools, in particular to a grinding wheel type lighter. Background Art

[0002] Grinding wheel lighters mainly rely on the friction between the grinding wheel and the flint to generate sparks, which in turn ignite the fuel or gas to form a flame. The grinding wheel and the flint are in very close contact, which results in a large frictional resistance to the rotation of the grinding wheel. It takes force to turn the grinding wheel, which can easily scratch your fingers. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0024] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.

[0025] The directional and positional terms used in this invention, such as up, down, front, back, left, right, inside, outside, top, bottom, and side, are merely references to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0026] A grinding wheel lighter, such as Figure 1-Figure 5 As shown, it includes a housing 1, a grinding wheel 2, and a pressing member 3. The grinding wheel 2 is rotatable relative to the housing 1, and the pressing member 3 is capable of sliding up and down relative to the housing 1. A coaxial gear 4 is provided on one side of the grinding wheel 2. A one-way ratchet structure is provided between the grinding wheel 2 and the gear 4, and a one-way rotation drive is formed by the one-way ratchet structure. The pressing member 3 is provided with a rack 301 meshed with the gear 4. When the pressing member 3 slides down relative to the housing 1, the grinding wheel 2 rotates. Specifically, when the pressing member 3 is pressed down, the rack drives the gear 4 to rotate clockwise, and the gear 4 drives the grinding wheel 2 to rotate through the one-way ratchet structure. On the other hand, when the pressing member 3 is pressed down, the rack drives the gear 4 to rotate counterclockwise, and under the action of the one-way ratchet structure, the grinding wheel 2 does not rotate. By arranging a rack, a gear, and a one-way ratchet structure between the grinding wheel and the pressing member, the driving rotation of the grinding wheel can be achieved by simply pressing the pressing member, which is more labor-saving than directly turning the grinding wheel.

[0027] Further, such as Figure 2 As shown, two supporting side plates 101 are formed on the shell 1 and are arranged at a certain distance apart. The grinding wheel 2 and the gear 4 are both arranged between the two supporting side plates 101, and a hinge shaft 5 is provided that passes through the supporting side plates 101, the grinding wheel 2 and the gear 4, so that the grinding wheel 2 and the gear 4 can be rotatably fixed between the two supporting side plates 101.

[0028] Furthermore, the one-way ratchet structure includes a ratchet 6 that forms a circumferential linkage with the grinding wheel 2 and a pawl 7 that forms a circumferential linkage with the gear 4 .

[0029] like Figure 6 As shown, the ratchet wheel 6 is integrated with the grinding wheel 2. The sidewall of the grinding wheel 2 near the gear 4 is provided with ratchet grooves 601 at equal intervals to form the ratchet wheel 6. This eliminates the need for additional parts and reduces costs. Furthermore, the grinding wheel 2 itself has a high hardness, which prolongs the service life of the formed ratchet wheel 6.

[0030] Further, such as Figure 6 、 Figure 7As shown, the center of the gear 4 is a first linkage hole, the pawl 7 is an annular member provided with a second linkage hole 701 and an inclined swing arm 702 is extended on the annular member, the outer end of the swing arm 702 forms an end that cooperates with the ratchet 6, and an elastic structure is provided to cause the end of the swing arm 702 to be stuck in the ratchet groove 601 of the ratchet 6; the hinge shaft 5 is provided with a linkage section 501, and the first linkage hole and the second linkage hole 701 both cooperate with the linkage section 501 to form a circumferential linkage between the pawl 7 and the gear 4.

[0031] Furthermore, the latch 7 is made of metal, and the swing arm 702 is a spring formed integrally on the latch 7 .

[0032] The hinge shaft 5 is composed of a first pin 502 and a second pin 503 connected together. The linkage section 501 is disposed on the second pin 503, and the second pin 503 is rotatable relative to the first pin 502. A connecting hole 504 is defined in one end of the first pin 502, and a protrusion at one end of the second pin 503 forms a connecting shaft 505, which extends into the connecting hole 504.

[0033] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
