Description

Technical Field

[0001] This application relates to the field of hairdressing tools, specifically a weight-adjustable hair clipper. Background Technology

[0002] Hairdressing scissors are an indispensable tool in a hairdresser's daily work, and their design usually focuses on the sharpness of the blades, the comfort of the grip, and the overall portability. However, few people pay attention to the impact of the weight of hairdressing scissors on a hairdresser's work. Each hairdresser has their own usage habits, and the weight of hairdressing scissors will produce different feels when cutting hair for different customers, thus creating different requirements for the weight of hairdressing scissors.

[0003] The existing barber scissors have a single weight design and cannot be adjusted according to the specific needs of barbers. As a result, they cannot meet the different needs of different customers, causing barbers to feel uncomfortable when dealing with different customers, and even affecting their work efficiency and performance. Utility Model Content

[0004] To address the different needs of barbers regarding the weight and center of gravity of the scissors when used by different customers, a scissor with adjustable weight was invented.

[0005] The above-mentioned objective of this utility model is achieved through the following technical solution: A weight-adjustable hair clipper includes a body with an adjustment groove. The adjustment groove has multiple slots in which a removable weight is engaged.

[0006] By adopting the above technical solution, the center of gravity and weight of the hair clippers can be adjusted by placing different numbers and materials of counterweights, thereby improving the work efficiency of hairdressers.

[0007] Optionally, the slot includes a first locking segment and a second locking segment that are connected, and the first locking segment and the second locking segment are arranged at an angle to each other, and the counterweight is simultaneously locked into the first locking segment and the second locking segment.

[0008] By adopting the above technical solution, the first and second locking segments, which are set at an angle, simultaneously lock and fix the counterweight, which can provide locking stability and prevent the counterweight from making abnormal noises or shaking when it is pushed or swung during the use of the hair clippers, thus affecting the hairdresser's feel.

[0009] Optionally, the bottom of the slot is provided with a positioning guide groove, and the counterweight is provided with a protruding positioning guide block on the side facing the slot. When the counterweight is inserted into the slot, the positioning guide block is aligned and inserted into the positioning guide groove.

[0010] By adopting the above technical solution, the use of positioning guide groove and positioning guide block serves two purposes: firstly, it guides the counterweight block when it is inserted into the first and second locking sections, making it easier for the counterweight block to be inserted into the angled first and second locking sections, thus facilitating the adjustment of the hair clipper's counterweight; secondly, it further enhances the stability of the counterweight block after installation, preventing abnormal noises or shaking that may occur when the counterweight block is pushed or swung during the use of the hair clipper, thus affecting the hairdresser's feel.

[0011] Optionally, when the counterweight is engaged in the slot, one end or one side of the counterweight extends outside the slot.

[0012] By adopting the above technical solution, it is easier for a person to manually grasp the counterweight.

[0013] Optionally, the counterweights have the same shape but different masses.

[0014] By adopting the above technical solutions, more options are available for adjusting the total weight and center of gravity, allowing barbers with different habits to choose the right one.

[0015] Optionally, the slots are spaced apart along the long axis of the machine body.

[0016] By adopting the above technical solution, the center of gravity of the counterweight adjustment is adjusted and changed along the long axis of the machine body, ensuring that the center of the hair clipper is centered.

[0017] Optionally, it also includes a cover body, which is detachably installed in the opening of the adjustment groove, and the side of the cover body facing the adjustment groove is also provided with a pressing block for pressing the counterweight.

[0018] By adopting the above technical solution, after the cover is closed, the counterweight is fixed by the pressure block, which further improves the stability of the counterweight, avoids the counterweight from shaking during use and avoids the counterweight from falling off when the hair clippers are hit, and improves the reliability of the hair clippers of this application.

[0019] Optionally, a slot is provided on one side of the adjustment groove, and the body is also equipped with a release mechanism located on the side of the adjustment groove away from the slot. The release mechanism includes a locking tongue with one end inserted into the adjustment groove and a trigger rod that pries the locking tongue out of the adjustment groove. The two ends of the cover are respectively provided with inserts and cards, and the cards have lock slots. When the cover is closed, the inserts are inserted into the slots, and the end of the locking tongue inserted into the adjustment groove is inserted into the lock slot.

[0020] By adopting the above technical solution, the cover and the body can be detachably connected through inserts and cards, which provides good stability while being easy to install and remove.

[0021] Optionally, a first magnet is fixed on the side of the cover facing the adjustment groove, and a second magnet is fixed in the adjustment groove. When the cover is closed, the first magnet and the second magnet are aligned and their magnetic poles face each other.

[0022] By adopting the above technical solution, when the trigger rod pries the locking tongue out of the adjustment groove, the locking tongue unlocks the card, the first magnet and the second magnet repel each other, causing the cover to lift up and making it easy to remove the cover, which facilitates the use of the hair clippers of this application and the adjustment of the counterweight.

[0023] In summary, this utility model has the following beneficial effects: By selecting different numbers and weights of configuration blocks and fixing them to different positions in the adjustment groove, the weight and center of gravity of the hair clippers can be adjusted, thus adapting to the usage habits of different hairdressers and making them more flexible to use.

Detailed Implementation

[0026] As attached Figure 1As shown, a hair clipper with adjustable counterweight includes a head 1, a body 2, a counterweight block 3, and a cover 4.

[0027] The head 1 is connected to one end of the body 2 and is used to cut hair.

[0028] The body 2 has a recessed adjustment groove 21 on one side.

[0029] A first magnet 22 is fixedly engaged at the center of the bottom of the adjusting groove 21. The shape of the first magnet 22 can be determined according to actual needs; here it is a circular piece.

[0030] The bottom of the adjustment slot 21 has multiple slots 211, which are located on both sides of the first magnet 22 and spaced apart along the long axis of the body 2. The number of slots 211 is related to the length of the body 2. Here, there are six slots 211. The adjustment slot 21 has three slots 211 on the side of the first magnet 22 closer to the head 1 and three slots 211 on the side of the first magnet 22 away from the head 1. The slots 211 on both sides of the first magnet 22 are symmetrically arranged about the axis of the first magnet 22.

[0031] The card slot 211 includes a first card receiving section 2111 and a second card receiving section 2112 that are connected to each other. The first card receiving section 2111 and the second card receiving section 2112 are arranged at an angle of α. The ends of the first card receiving section 2111 and the second card receiving section 2112 that are far apart are both open.

[0032] In addition, the bottom of the slot 211 is provided with a positioning guide groove 2113, which is a circular groove; there are two positioning guide holes, located in the first locking section 2111 and the second locking section 2112 respectively.

[0033] The number of counterweights 3 is equal to the number of slots 211, and the shape of the counterweights 3 is adapted to the shape of the slots 211 so that the counterweights 3 are engaged in the slots 211.

[0034] The counterweight 3 includes a first counterweight section 31 and a second counterweight section 32. The first counterweight section 31 and the second counterweight section 32 are set at an angle, and the angle is also α.

[0035] The cross-section of the first counterweight section 31 in the vertical length direction is the same as the cross-section of the first snap-fit ​​section 2111 in the vertical length direction, but the length of the first counterweight section 31 is greater than that of the first snap-fit ​​section 2111.

[0036] The cross-section of the second counterweight section 32 in the vertical length direction is the same as the cross-section of the second locking section 2112 in the vertical length direction, but the length of the second counterweight block 3 is greater than that of the second locking section 2112.

[0037] When the counterweight 3 is engaged in the slot 211, the side of the first counterweight section 31 is in contact with the side of the first engaging section 2111, and the side of the second counterweight section 32 is in contact with the side of the second engaging section 2112. At the same time, one end of the first counterweight section 31 extends out of the first engaging section 2111, and one end of the second counterweight 3 extends out of the second engaging section 2112, which makes it easy for a person to hold the counterweight 3.

[0038] As attached Figure 2 As shown, the counterweight 3 has a protruding positioning guide block 33 on the side facing the adjustment groove 21. There are two positioning guide blocks 33, which are convenient to be positioned on the first counterweight section 31 and the second counterweight section 32.

[0039] As attached Figure 1 and attached Figure 2 As shown, when the counterweight 3 is inserted into the slot 211 from the outside of the self-adjusting groove 21, the positioning guide block 33 is first aligned and inserted into the positioning guide groove 2113. The projection of the counterweight 3 along the axis of the positioning guide block 33 matches and aligns with the slot 211, so that the counterweight 3 is smoothly filled into the slot 211.

[0040] The counterweights 3 have the same shape, and the weight of the counterweights 3 is different due to the density of the internal filling material. Thus, the center of gravity of the hair clippers can be adjusted along the long axis of the machine body 2 by adjusting the counterweights 3 to be engaged in different slots 211.

[0041] As attached Figure 1 As shown, the shape of the cover 4 is adapted to the shape of the opening of the adjustment groove 21, and it covers the opening of the adjustment groove 21.

[0042] As attached Figure 1 and attached Figure 2 As shown, the cover 4 is also provided with a groove 41 and a pressing block 42 on the side facing the adjustment groove 21. The groove 41 is located at the center of the cover on the side facing the adjustment groove 21, and a second magnet 43 is fixedly engaged inside it. The magnetic poles of the second magnet 43 and the first magnet 22 are opposite. When the cover 4 is closed, the first magnet 22 and the second magnet 43 are aligned and their poles are opposite to each other.

[0043] The number of pressing blocks 42 is equal to the number of slots 211, which is six in this case. When the cover 4 is aligned with the cover adjustment groove 21, the pressing blocks 42 and the slots 211 are aligned one by one.

[0044] The end of the cover 4 facing the head 1 is provided with an insert 44, which extends outward.

[0045] As attached Figure 3 As shown, the machine body 2 has a slot 23 on the side wall of the adjustment groove 21 near the machine head 1, and the insert 44 can be aligned and inserted into the slot 23.

[0046] A card 45 is provided at the end of the cover 4 away from the machine head 1. The card 45 extends perpendicularly to the side of the cover 4 facing the adjustment groove 21. A locking groove 451 is opened on the side of the card 4 facing away from the center of the cover 4.

[0047] As attached Figure 3 and attached Figure 4 As shown, the machine body 2 has an installation cavity 24 at the end away from the machine head 1, and the adjustment groove 21 has a through hole 25 on the side wall away from the machine head 1, which passes through the installation cavity 24 and the adjustment groove 21.

[0048] As attached Figure 3 and attached Figure 5 As shown, when the cover 4 is closed, the insert 44 is inserted into the slot 23, the card 45 is inserted into the adjustment slot 21, and the locking slot 451 is aligned with the through hole 25.

[0049] As attached Figure 6 As shown, the mounting cavity 24 is also equipped with an unlocking mechanism 5. The unlocking mechanism 5 includes a rotating shaft 51, a locking element 52, and a trigger rod 53. The rotating shaft 51 is fixed in the mounting cavity 24, and the locking element 52 is sleeved and rotatably connected to the rotating shaft 51.

[0050] With the rotating shaft 51 as the center, the locking part 52 has a locking part 521 and a linkage part 522 on both sides.

[0051] The locking part 521 has a protruding latch 5211 on the side facing the through hole 25. The latch 5211 rotates with the locking part 521 around the rotating shaft 51 and passes through the through hole 25 and is inserted into the lock groove 451.

[0052] The linkage part 522 is recessed on the side facing the adjustment groove 21 to form a receiving groove 5221, and a locking spring 54 is inserted into the receiving groove 5221. One end of the locking spring 54 abuts against the bottom of the receiving groove 5221, and the other end abuts against the inside of the mounting cavity 24, forcing the locking part 521 to rotate toward the through hole 25.

[0053] A through-hole 26 is provided on the side of the mounting cavity 24 away from the adjustment groove 21. The trigger rod 53 passes through the sliding hole 26 and is slidably connected to the sliding hole 26. A limiting edge 531 is provided on the side of the trigger rod 53 facing the adjustment groove 21. The outer contour dimension of the limiting edge 531 is larger than that of the sliding hole 26, so as to prevent the trigger rod 53 from sliding out of the body 2.

[0054] A trigger block 532 is also protruding on the side of the limiting line 531 facing the adjustment groove 21, and the trigger block 532 abuts against the side of the linkage part 522 facing away from the adjustment groove 21.

[0055] Combined with appendix Figure 5 and attached Figure 6Thus, the trigger rod 53 is pushed along the sliding hole 26 toward the adjustment groove 21 side. The trigger block 532 will push the linkage part 522 to rotate toward the adjustment groove 21 side, and in conjunction, pry the locking part 521 to rotate away from the through hole 25, so that the locking tongue 5211 is pulled out of the locking groove 451 and retracted into the through hole 25, so that the end of the cover 4 away from the machine head 1 is unlocked.

[0056] As attached Figure 6 As shown, to reduce wear and tear on the trigger lever 53 and stress fracture due to lever arm amplification, the release mechanism 5 also includes a trigger key 55. One end of the trigger key 55 abuts against the outward end of the trigger lever 53, and the other end extends out of the body 2 to replace the pressure on the end of the trigger lever 53.

[0057] The specific operation of this hair clipper application is as follows: Press the trigger button 55 to retract the bolt 5211 into the through hole 25, and unlock the end of the cover 4 away from the head 1. Then, the repulsive force of the first magnet 22 and the second magnet 43 causes the end of the cover 4 away from the head 1 to be lifted up. The barber holds the end of the cover 4 away from the head 1 and pulls the insert 44 out of the slot 23 to remove the cover 4. The counterweight 3 can be freely adjusted and replaced to achieve the desired effect. Then insert the insert 44 into the slot 23, close the cover 4 and put it back on, insert the card 45 into the adjustment groove 21 so that the locking tongue 5211 engages with the locking groove 451, and press the counterweight 3 in the adjustment groove 21 with the pressing block 42 to make it more stable, thus completing the adjustment.

[0058] Therefore, the hair clippers of this application can adjust the weight and center of gravity of the hair clippers by selecting the number and quality of the counterweights 3 and the position of the slots 211, so as to adapt to the habits and needs of different hairdressers and improve haircutting efficiency.
