Description

Technical Field

[0001] The utility model belongs to the field of hair styling tools, and particularly relates to a frog-type four-leg locking arm structure. Background Art

[0002] Existing hair styling tools, such as hair straighteners and curling irons, typically include upper and lower clamping plates that are hinged to each other. To keep the upper and lower clamping plates in an open position, spaced apart from each other, for easy styling of hair, an elastic mechanism is provided between the upper and lower clamping plates to maintain the two plates in an open position. During use, the consumer presses the upper and lower clamping plates together to clamp and style the hair. When the user releases the pressure, the upper and lower clamping plates return to the open position due to the elastic force of the elastic mechanism, allowing the consumer to style another section of hair.

[0003] During the hair styling stage, consumers need to continuously press the upper and lower clamps to keep them closed to continuously heat and style the hair or blow-dry the hair. However, continuous pressing can easily cause discomfort and effort to the consumer's hands, which is not conducive to the consumer's continuous hair styling operation. Summary of the Invention

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] like Figure 1-3 As shown, the utility model provides a frog-type four-legged locking arm structure, comprising a main body 1 and a clamping plate 1 2 and a clamping plate 2 3 respectively hinged to the main body 1, the main body 1 comprising an air inlet end 11 and an air outlet end 12, the clamping plate 1 2 and the clamping plate 2 3 are both hinged to one side of the main body 1 near the air inlet end 11, and the clamping plate 1 2 and the clamping plate 2 3 can move between an open state and a closed state;

[0033] Among them, such as Figure 1 As shown, the closed state refers to pressing the clamping plate 1 2 and the clamping plate 2 3 so that the clamping plate 1 2 and the clamping plate 2 3 simultaneously approach the main body 1 and fit together to achieve clamping of the hair;

[0034] like Figure 3 As shown, the open state means that the splint 1 2 and the splint 2 3 rotate in a direction away from the main body 1, so that the splint 1 2 and the splint 2 3 are away from each other.

[0035] Specifically, two elastic members 13 are provided on the outer peripheral wall of the main body 1, and the ends of the two elastic members 13 are respectively elastically connected to the inner sides of the clamping plate 1 2 and the clamping plate 2 3, so that the clamping plate 1 2 and the clamping plate 2 3 always remain in an open state away from each other when not affected by external forces.

[0036] Specifically, such as Figure 4-6 As shown, a bracket 4 is fixedly provided on the peripheral wall of the main body 1, and an outer side surface of the bracket 4 is provided with an inwardly concave rectangular flat surface 41, so that the flat surface 41 forms two limiting steps 1 42 along the length direction of the main body 1, and a locking arm 5 is slidably connected on the flat surface 41 and between the two limiting steps 1 42, and at least a portion of the locking arm 5 is respectively located between the clamping plate 1 2 and the main body 1, and between the clamping plate 2 3 and the main body 1;

[0037] The locking arm 5 includes a plate body 51, and the plate body 51 approaches or slides against the flat surface 41 and moves forward and backward along the length direction of the main body 1. During the process, the front end 511 and the rear end 512 of the plate body 51 will respectively abut against the two limit steps 42 at different positions, thereby limiting the forward and backward sliding distance of the locking arm 5; the plate body 51 is provided with two symmetrically arranged cross arms 52 on both sides of the front end 511 close to the air outlet end 12, and the cross arms 52 surround the peripheral wall of the main body 1 and extend perpendicular to the length direction of the main body 1, and the cross arms 52 are provided with a latch 521 extending toward the air outlet end 12, and the inner sides of the splint 1 2 and the splint 2 3 are provided with slots 6 corresponding to the latch 521;

[0038] When in use, the consumer manually presses the clamping plate 1 2 and the clamping plate 2 3 so that the two rotate toward the main body 1 and present a closed state. At this time, the locking arm 5 is pushed toward the air outlet end 12 so that the locking arm 5 moves forward and the two latches 521 on the locking arm 5 are respectively inserted into the slots 6 on the clamping plate 1 2 and the clamping plate 2 3, so that the locking arm 5 is respectively engaged and locked with the clamping plate 1 2 and the clamping plate 2 3, thereby locking the clamping plate 1 2 and the clamping plate 2 3 and maintaining the closed state; in the closed state, it is convenient for consumers to continue to perform hairdressing operations on their hair without the need for consumers to manually and continuously press the clamping plate 1 2 and the clamping plate 2 3, thereby achieving the purpose of saving effort. At the same time, after using the product, it can save space in the closed state for easy storage and carrying;

[0039] When it is necessary to unlock the closed state, it is only necessary to push the locking arm 5 toward the air inlet end 11 to make the locking arm 5 retreat and disengage the latch 521 from the slot 6. Under the elastic force of the elastic member 13, the splint 1 2 and the splint 2 3 return to the open state again, which is practical and convenient.

[0040] Specifically, such as Figure 7-9 As shown, two symmetrically arranged longitudinal arms 53 are provided on both sides of the rear end 512 of the plate body 51 near the air inlet end 11. The longitudinal arms 53 extend toward the air inlet end 11. The bracket 4 is provided with a limiting groove 43 corresponding to the longitudinal arm 53. The longitudinal arm 53 is slidably connected to the limiting groove 43. Through the setting of the limiting groove 43, the locking arm 5 is kept moving in the front-to-back direction along the length of the main body 1, thereby guiding the movement of the locking arm 5.

[0041] Furthermore, on the bracket 4, limit blocks 44 are respectively provided on both sides of the limit step 1 42 near the air inlet end 11. The limit blocks 44 extend perpendicularly to the length direction of the main body 1. The two limit blocks 44 respectively slide against the outer side surfaces of the two longitudinal arms 53, so that when the locking arm 5 moves, the locking arm 5 is effectively prevented from falling off from the main body 1.

[0042] Preferably, the inner side surface of one end of the longitudinal arm 53 close to the air inlet end 11 is further provided with a wave point 531 protruding toward the main body 1, and the bracket 4 is provided with a first arcuate groove 45 and a second arcuate groove 46 corresponding to the wave point 531. The first arcuate groove 45 and the second arcuate groove 46 are arranged along the length direction of the main body 1, and the first arcuate groove 45 is closer to the air outlet end 12 than the second arcuate groove 46.

[0043] When in use, in the closed state, the locking arm 5 is pushed forward toward the air outlet end 12, and after the latch 521 is plugged into the slot 6, the wave point 531 is just engaged with the first arc groove 45, thereby locking the position of the locking arm 5; when the locking arm 5 is pushed backward with force toward the air inlet end 11, the wave point 531 slides out of the first arc groove 45 and moves in the direction of the second arc groove 46 until the wave point 531 is engaged with the second arc groove 46, at this time, the latch 521 is just disengaged from the slot 6, thereby forming the open state of the splint 1 2 and the splint 2 3; through the setting of the wave point 531, the first arc groove 45 and the second arc groove 46, the locking arm 5 has a fixing effect in the open state and the closed state, thereby limiting the random sliding of the locking arm 5 and improving the stability of the product; at the same time, it can also enhance the consumer's feel of locking and unlocking the closed state, thereby improving the consumer's user experience.

[0044] Specifically, such as Figure 9 As shown, a limiting arm 522 is provided on one end of the cross arm 52 away from the plate body 51, and the limiting arm 522 extends perpendicularly to the length direction of the main body 1. A holder 47 is provided on the outer peripheral wall of the bracket 4, and a limiting hole 471 corresponding to the limiting arm 522 is provided in the holder 47. The limiting arm 522 is slidably connected to the limiting hole 471. The setting of the limiting arm 522 and the limiting hole 471 has a limiting effect on the movement of the locking arm 5, further preventing the locking arm 5 from falling off the bracket 4;

[0045] Further, if Figure 9-10As shown, the outer side surface of the limiting arm 522 is also provided with a fixing block 523 protruding outward, and a limiting step 2 524 is formed between the fixing block 523 and the limiting arm 522, and the fixing block 523 is limitedly abutted against the end wall of the holder 47 away from the plate body 51 through the limiting step 2 524; the fixing blocks 523 and the limiting step 2 524 on the two limiting arms 522 are symmetrically arranged; when in use, after the limiting arm 522 passes through the limiting hole 471, the limiting step 2 524 in the fixing block 523 abuts against the end wall of the holder 47, thereby preventing the limiting arm 522 from shaking in the flat surface 41 and affecting the stability of use, and at the same time, it can also effectively prevent the limiting arm 522 from falling off from the limiting hole 471, thereby improving the movement stability of the locking arm 5.

[0046] Specifically, such as Figure 1 As shown, in order to further improve the convenience of pushing the locking arm 5, the locking arm 5 is centrally arranged between the clamping plate 1 2 and the clamping plate 2 3, and a push block 54 is centrally provided on the outer side of the plate body 51, and the push block 54 is fixedly connected to the plate body 51; in the closed state, the clamping plate 1 2 and the clamping plate 2 3 can cover the outer side of the locking arm 5 as much as possible, so that a small gap 7 is formed between the clamping plate 1 2 and the clamping plate 2 3, thereby improving the overall aesthetics of the product, and at this time, the push block 54 is arranged in the gap 7;

[0047] Preferably, the ends of the first and second clamping plates 2 and 3 near the gap 7 are further provided with avoidance grooves 71 corresponding to the push block 54. By providing the avoidance grooves 71, the volume of the push block 54 is increased as much as possible while ensuring the overall aesthetics of the product, thereby increasing the contact area between the push block 54 and the consumer's fingers and improving the convenience of the consumer in pushing the push block 54.

[0048] Furthermore, the push block 54 and the plate body 51 can be connected by snapping, bonding or an integrally formed structure.

[0049] Specifically, in order to improve the durability and practicality of the locking arm 5 without destroying the overall aesthetics of the locking arm 5, the length of the flat surface 41 (the length in the front-to-back direction) is preferably set between 15 mm and 30 mm, and the width of the flat surface 41 (the length perpendicular to the front-to-back direction) is preferably set between 10 mm and 25 mm. Accordingly, the length and width of the plate body 51 can be preferably set to 22 mm and 18.6 mm to match the flat surface 41. The flat surface 41 and the plate body 51 are both roughly square.

[0050] The following is a detailed description of the working principle of the utility model;

[0051] During installation, the locking arm 5 is slidably fitted on the flat surface 41 of the bracket 4. At this time, the longitudinal arm 53 is slidably connected to the limiting groove 43 and the limiting block 44 is slidably abutted against the outer side of the longitudinal arm 53, while the limiting arm 522 on the transverse arm 52 is slidably connected to the limiting hole 471; then the pushing block 54 is fixedly installed on the outer side wall of the plate body 51, and finally the clamping plate 1 2 and the clamping plate 2 3 are installed so that they cover the outer side surface of the locking arm 5 in the closed state, thereby completing the installation of the locking arm 5;

[0052] During use, the first and second clamping plates 2, 3 are pressed to fit the main body 1 and present a closed state. Then, the push block 54 is manually pushed to drive the locking arm 5 to move forward toward the air outlet end 12. When the latch 521 is inserted into the slot 6 and the wave point 531 is synchronously engaged with the first arc-shaped groove 45, the closed state is locked, thereby achieving the purpose of relaxing the consumer's hand.

[0053] When the closed state needs to be released, it is only necessary to push the push block 54 toward the air inlet end 11 so that the push block 54 drives the locking arm 5 to retreat. When the latch 521 disengages from the slot 6 and the wave point 531 is synchronously engaged in the second arc groove 46, the closed state is released. Under the action of the elastic member 13, the splint 1 2 and the splint 2 3 return to the open state again.

[0054] The innovation of the present utility model lies in that, through the arrangement of the plate body, longitudinal arm, transverse arm and the limiting arm, the locking arm is made into a frog-type four-legged structure and slides against the outer peripheral wall of the main body, thereby effectively increasing the contact area between the locking arm and the main body, thereby improving the locking stability of the locking arm on the splint one and the splint two; at the same time, through the arrangement of the base and the limiting block, the sliding stability of the locking arm is improved, so that it maintains sliding balance to prevent the locking arm from shifting and forming a sliding obstacle, thereby improving the stability and durability of the locking arm.
