Description

Technical Field

[0001] This utility model relates to the field of lighter grinding wheel technology, and in particular to a lighter grinding wheel. Background Technology

[0002] Lighters are an indispensable tool in daily life because they are easy to carry and convenient to start a fire. There are a wide variety of lighters on the market, and the grinding wheel lighter, as a classic style, is still popular. When using it, the user rotates the grinding wheel to make the grinding wheel rub against the flint at the bottom to generate sparks, and at the same time presses the fuel switch to use the sparks to start a fire.

[0003] A search revealed a Chinese patent (authorization announcement number CN212108489U) disclosing a grinding wheel structure for a lighter, comprising an inner grinding wheel with a central hole, and a first side wheel and a second side wheel respectively disposed on both sides of the inner grinding wheel; a receiving cavity is formed on the side of the first side wheel facing the inner grinding wheel, and an insertion rod passing through the central hole of the inner grinding wheel is disposed on the receiving cavity, with the other end of the insertion rod fixed to the second side wheel; a limiting strip is provided on the insertion rod along its own length direction; a clearance groove is formed on the inner sidewall of the central hole of the inner grinding wheel for the limiting strip to pass through, and one side of the inner grinding wheel is embedded in the receiving cavity. This patented technology has the advantages of simple structure, convenient installation, and stable and reliable performance.

[0004] However, the above-mentioned device still has some shortcomings in actual use. The most obvious one is that the ignition structure of the lighter does not have a safety device, which makes it easy for children to operate and ignite, posing a certain safety hazard. It needs to be improved urgently. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main purpose of this utility model is to provide a lighter grinding wheel.

[0006] The technical solution of this utility model is as follows: a lighter grinding wheel includes a grinding wheel body, wear-resistant toothed plates are fixedly connected at equal intervals on the outer side of the grinding wheel body, side wheels are provided on both sides of the grinding wheel body, and a sliding groove is opened inside each side wheel. A push block is slidably connected inside each sliding groove. A rotating seat is provided on the outer side of the grinding wheel body, and a second locking hole is opened on the side of the rotating seat near the side wheel. A second locking post is fixedly connected on the side of each push block near the rotating seat. The second locking post engages with the corresponding second locking hole. An unlocking mechanism is provided inside the side wheel.

[0007] By adopting the above technical solution, when there is a child in the lighter storage area, the safety structure can be activated to turn the long screw, thereby causing the moving block to slide in the groove. This causes pressure on the push block, and the grinding wheel body is fixed by the engagement of the second locking post and the second locking hole. This will hinder the child from lighting the lighter. The slow movement of the long screw will wear down the child's patience, making the unlocking process more complicated. The child cannot easily light the lighter, thus minimizing safety hazards.

[0008] In a preferred embodiment, the unlocking mechanism includes a movable block slidably connected to the inner wall of the groove, with a long screw rotatably connected to the top of each movable block, the movable block abutting against the side of the push block, and a spring sleeved on the outer side of each locking post.

[0009] By adopting the above technical solution, when it is necessary to unlock and use the grinding wheel body, simply rotate the long screw in the opposite direction.

[0010] In a preferred embodiment, a replacement mechanism is provided on the outer side of the grinding wheel body. The replacement mechanism includes a retainer fixedly connected to one side of the two side wheels that are close to each other. The retainer is engaged with a slot. A double-ended screw is provided inside the grinding wheel body. The double-ended screw penetrates the interior of the side wheels. A fixing nut is threaded to both sides of the double-ended screw.

[0011] By adopting the above technical solution, the two side wheels and the grinding wheel body can be combined into a whole through the cooperation of the card holder and the card slot, so as to facilitate the assembly of the grinding wheel body.

[0012] In a preferred embodiment, the card holder is provided with a stabilizing mechanism, which includes a magnetic sheet embedded in one of the card holders and an iron sheet that works in conjunction with the magnetic sheet embedded in the other card holder on the side away from the side wheel.

[0013] By adopting the above technical solution, the connection between the two side wheels and the grinding wheel body can be increased through the attraction between the iron sheet and the magnetic sheet.

[0014] In a preferred embodiment, the grinding wheel body is provided with positioning mechanisms on both sides. The positioning mechanism includes a locking pin that is fixedly connected to one side of the side wheel at equal intervals. Both sides of the grinding wheel body are provided with locking holes that cooperate with the locking pins. The locking pins and locking holes are engaged with each other.

[0015] By adopting the above technical solution, the use of the first locking post and the first locking hole can play an important positioning role.

[0016] In a preferred embodiment, each of the side wheels has a storage groove inside that cooperates with the fixing nut, and the fixing nut abuts against the inner wall of the corresponding storage groove. The outer side of the wear-resistant tooth is coated with a wear-resistant coating.

[0017] By adopting the above technical solution and setting wear-resistant coatings and wear-resistant tooth plates, the wear resistance of the grinding wheel body can be further improved.

[0018] In a preferred embodiment, the sum of the widths of the two card holders is equal to the width of the inner wall of the card slot, and the top end of the long screw extends to the outside of the side wheel and is fixedly connected to an adjustment knob.

[0019] By adopting the above technical solution, the long screw can be rotated by adjusting the knob settings.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, when a child is in the lighter storage area, a safety structure can be activated. The long screw is turned, causing the moving block to slide within the groove, thereby squeezing the push block. The two locking pins and two locking holes engage to fix the grinding wheel body, thus hindering the child from lighting the lighter. The slow movement of the long screw will wear down the child's patience, making the unlocking process more complicated and preventing the child from easily lighting the lighter, thus minimizing safety hazards. Meanwhile, when adults are carrying the lighter, they can easily slide the grinding wheel body to light it without turning the long screw. The use of wear-resistant teeth increases the wear resistance of the grinding wheel body, thereby extending its service life.

[0022] 2. In this utility model, by using the card holder and the card slot together, the two side wheels and the grinding wheel body can be combined into a whole, which facilitates the assembly of the grinding wheel body and the replacement of the damaged grinding wheel body, thus avoiding the phenomenon of replacing the entire lighter due to the damage of the individual grinding wheel body.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-4 A lighter grinding wheel includes a grinding wheel body 1. Wear-resistant toothed plates 2 are fixedly connected at equal intervals on the outer side of the grinding wheel body 1. Side wheels 3 are provided on both sides of the grinding wheel body 1. Each side wheel 3 has a sliding groove 12 inside, and a push block 11 is slidably connected inside each sliding groove 12. A rotating seat 10 is provided on the outer side of the grinding wheel body 1. A locking hole 15 is provided on the side of the rotating seat 10 near the side wheel 3. Each push block 11 has a locking post 16 fixedly connected on the side near the rotating seat 10. Each locking post 16 engages with the corresponding locking hole 15. An unlocking mechanism is provided inside the side wheel 3. When there is a child in the lighter storage area, the safety structure can be activated to engage the long screw 14. The screw is turned, which causes the moving block 13 to slide in the slide groove 12, thereby squeezing the push block 11. The locking pin 16 and the locking hole 15 are engaged to fix the grinding wheel body 1. This will hinder children from lighting the lighter. The long screw 14 moves slowly, which will wear down children's patience and make the unlocking process more complicated. Children cannot easily light the lighter, which poses a small safety hazard. At the same time, when adults carry the lighter, they can easily slide the grinding wheel body 1 to light the lighter without turning the long screw 14. The wear-resistant toothed plate 2 can increase the wear resistance of the grinding wheel body 1, thereby increasing the service life of the grinding wheel body 1.

[0030] Reference Figure 3 The unlocking mechanism includes a movable block 13 that is slidably connected to the inner wall of the slide groove 12. The top of each movable block 13 is rotatably connected to a long screw 14. The movable block 13 abuts against the side of the push block 11 that is close to it. The outer side of each locking post 16 is fitted with a spring 17. When it is necessary to unlock the grinding wheel body 1, simply rotate the long screw 14 in the opposite direction.

[0031] Reference Figure 2The grinding wheel body 1 is provided with a replacement mechanism on its outer side. The replacement mechanism includes a retainer 9 fixedly connected to the two side wheels 3 on the side closest to each other. The retainer 9 is engaged with the slot 6. The grinding wheel body 1 is provided with a double-ended screw 5 inside. The double-ended screw 5 passes through the inside of the side wheel 3. The two sides of the double-ended screw 5 are threaded with fixing nuts 4. Through the cooperation of the retainer 9 and the slot 6, the two side wheels 3 and the grinding wheel body 1 can be combined into a whole, so as to facilitate the assembly of the grinding wheel body 1. At the same time, it is convenient to replace the damaged grinding wheel body 1, avoiding the phenomenon of replacing the entire lighter due to the damage of the individual grinding wheel body 1.

[0032] Reference Figure 2 The card holder 9 is equipped with a stabilizing mechanism. The stabilizing mechanism includes a magnetic sheet embedded in one of the card holders 9 and an iron sheet that works with the magnetic sheet on the side of the other card holder 9 away from the side wheel 3. By attracting the iron sheet and the magnetic sheet, the connection between the two side wheels 3 and the grinding wheel body 1 can be increased, making the whole system more stable in use.

[0033] Reference Figure 2 The grinding wheel body 1 is provided with positioning mechanisms on both sides. The positioning mechanisms include locking pins 7 that are fixedly connected to one side of the side wheel 3 at equal intervals. Both sides of the grinding wheel body 1 are provided with locking holes 8 that cooperate with the locking pins 7. The locking pins 7 and locking holes 8 are engaged. The use of locking pins 7 and locking holes 8 can play an important positioning role, making the assembly of the side wheel 3 and the grinding wheel body 1 more convenient and ensuring the accuracy of the assembly work.

[0034] Reference Figure 2 Each of the side wheels 3 has a storage groove inside that works with the fixing nut 4. The fixing nut 4 abuts against the inner wall of the corresponding storage groove. The outer side of the wear-resistant toothed plate 2 is coated with wear-resistant paint. The storage groove makes it easy to store the fixing nut 4. The wear-resistant paint and wear-resistant toothed plate 2 further improve the wear resistance of the grinding wheel body 1 and extend its service life.

[0035] Reference Figure 3 The sum of the widths of the two card holders 9 is equal to the width of the inner wall of the card slot 6. The top of the long screw 14 extends to the outside of the side wheel 3 and is fixedly connected to an adjustment knob. The long screw 14 can be rotated by adjusting the knob.

[0036] Working principle: When a child is in the lighter storage area, the safety structure can be activated by turning the long screw 14, which causes the moving block 13 to slide in the slide groove 12, thereby squeezing the push block 11. The locking pin 16 and the locking hole 15 are engaged to fix the grinding wheel body 1, which will hinder the child from lighting the lighter. The slow movement of the long screw 14 will wear down the child's patience, making the unlocking process more complicated and preventing the child from easily lighting the lighter, thus minimizing safety hazards. At the same time, when adults are carrying the lighter, they can easily slide the grinding wheel body 1 to light the lighter without turning the long screw 14. The wear-resistant toothed plate 2 increases the wear resistance of the grinding wheel body 1, thereby improving its service life. When it is necessary to unlock the grinding wheel body 1, simply turn the long screw 14 in the opposite direction.

[0037] By using the card holder 9, double-ended screw 5, fixing nut 4 and card slot 6 together, the two side wheels 3 and the grinding wheel body 1 can be combined into a whole, which facilitates the assembly of the grinding wheel body 1 and the replacement of the damaged grinding wheel body 1. This avoids the phenomenon of replacing the entire lighter due to the damage of the individual grinding wheel body 1. Furthermore, the attraction between the iron sheet and the magnetic sheet increases the tightness of the connection between the two side wheels 3 and the grinding wheel body 1, making the whole lighter more stable in use.

[0038] The above are merely preferred embodiments of this application and are not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
