Description

Technical Field

[0001] This utility model relates to the field of lighter technology, specifically a novel lighter grinding wheel structure. Background Technology

[0002] A lighter is a common ignition tool. By rotating the grinding wheel, friction is created between the grinding wheel and the flint. This friction produces a spark, which ignites the flammable gas inside the lighter, thus completing the ignition. Disposable lighters use piezoelectric ceramic igniters, but non-disposable lighters usually still use the friction between the grinding wheel and the flint to generate a spark for ignition.

[0003] According to publication number CN222352368U, a lighter grinding wheel is provided, including a wheel body. The wheel body has a mounting hole that penetrates through it, allowing the wheel body to be mounted on a lighter. The surface of the wheel body has toothed protrusions arranged circumferentially. When the wheel body rotates, the toothed protrusions can contact the flint. During this contact, the toothed protrusions generate a spark through friction with the flint, thus igniting the lighter. The toothed protrusions replace the wheel body in contact with the flint during ignition, reducing the contact area and minimizing damage to the wheel body during rotation, thereby increasing the lifespan of the lighter grinding wheel. Furthermore, the toothed protrusions generate a more stable spark, further improving ignition efficiency.

[0004] While the above structure can improve the lifespan of the lighter's grinding wheel, most lighters are made of plastic. When installing the grinding wheel, the plastic shell is usually squeezed by external force, and then the limiting shaft is inserted into the mounting groove. This makes the installation and replacement of the grinding wheel inconvenient and can easily damage the plastic shell, rendering the lighter unusable.

[0005] Therefore, this utility model provides a novel lighter grinding wheel structure. Utility Model Content

[0008] Furthermore, the locking block is slidably connected to the sleeve, and the connecting shaft is slidably connected to the sleeve.

[0009] The beneficial effect of the above-mentioned further solution is that it makes it easier for staff to adjust the position of the insertion rod when using the inner grinding wheel of a lighter for installation.

[0022] 2. This new type of lighter grinding wheel structure, by setting a first insertion shaft, a second insertion shaft and an inner grinding wheel, allows the operator to effectively limit the inner grinding wheel when using the lighter. When the operator needs to replace the inner grinding wheel, they only need to manually pull out the first insertion shaft and the second insertion shaft. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-5 As shown, a novel lighter grinding wheel structure includes a first side wheel 1 and a rotating assembly. The rotating assembly is located on the front side of the outer wall of the first side wheel 1. The rotating assembly includes a connecting shaft 201, a locking block 202 fixedly connected to the front side of the outer wall of the connecting shaft 201, a sleeve 203 fitted onto the outer wall of the locking block 202, a moving groove 204 formed on the inner wall of the sleeve 203 corresponding to the locking block 202, and a rotating hole 205 formed on the outer wall of the sleeve 203 corresponding to the connecting shaft 201. The sleeve 203 has two rotating holes on its left and right sides. A connecting rod 206 is fixedly connected to the side. An insertion rod 207 is fixedly connected to the rear side of the outer wall of the connecting rod 206. A limit ball 208 is fixedly connected to the end of the insertion rod 207 away from the connecting rod 206. An installation plate 209 is sleeved on the outer wall of the insertion rod 207. A locking block 202 is slidably connected to a sleeve 203. A connecting shaft 201 is slidably connected to a sleeve 203. The insertion rod 207 is slidably connected to the installation plate 209. A notch 10 is opened at the corresponding position of the outer wall of the installation plate 209 and the sleeve 203.

[0031] The working principle or usage method of this embodiment is as follows: When the operator needs to install or maintain the inner grinding wheel 6, the sleeve 203 is manually pulled. At this time, the sleeve 203 slides on the outer wall of the connecting shaft 201. When it is in a suitable position, the locking block 202 limits the sleeve 203. Then the sleeve 203 is placed in the notch 10. Then the sleeve 203 is manually pushed. At this time, the insertion rod 207 moves accordingly. The limiting ball 208 passes through the limiting hole 3, and the insertion rod 207 enters the interior of the mounting plate 209, thereby completing the limiting of the sleeve 203.

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a limiting hole 3 is provided on the outer wall of the mounting plate 209 at the corresponding position of the insertion rod 207.

A second side wheel 9 is fixedly connected to the rear side of the outer wall of the second insertion shaft 5. The first insertion shaft 4 and the second insertion shaft 5 are slidably connected.

[0033] The working principle or usage method of this embodiment is as follows: When the operator needs to replace the inner grinding wheel 6, pull the first side wheel 1 so that the first insertion shaft 4 disengages from the second insertion shaft 5. Then, pull the second insertion shaft 5 out of the inner grinding wheel 6 to complete the replacement of the inner grinding wheel 6. When the operator uses the inner grinding wheel 6, the first side wheel 1 drives the first insertion shaft 4 to rotate, the first insertion shaft 4 drives the second insertion shaft 5 to rotate, and the second insertion shaft 5 drives the inner grinding wheel 6 to move.
