Description

Technical Field

[0001] The utility model relates to hair curling equipment, in particular to a hair curler with adjustable diameter. Background Art

[0002] A hair curling iron is a tool used to curl and perm hair. It usually has one or more heated rod-shaped parts, which can be cylindrical or have a wavy or spiral shape to create different curling effects on the hair. The hair curling iron is heated by electricity, causing the hair to bend and set when it comes into contact with the hot surface, thus creating a lasting curling effect. When using a hair curling iron, it is necessary to operate it carefully to avoid scalding the scalp or damaging the hair. Before use, make sure the hair is dry and apply a heat protection spray to reduce damage to the hair. In addition, hair curling irons with different materials and designs may be suitable for different types of hair and curling effects, so it is very important to choose a hair curling iron that suits oneself.

[0003] A Chinese patent with the authorization publication number CN218737637U discloses a diameter-adjustable hair curling device. In the cavity, the shaping rod is installed in a limited sliding manner, so that its up and down positions can be precisely adjusted. The lower end surface of the shaping rod is designed with a rectangular movable cavity that is recessed inward. A central shaft is installed in this cavity, and a driven arm is fixedly sleeved on the central shaft. The other end of the driven arm is rotationally connected to the driving arm, and the lower end of the driving arm is rotationally installed on the side wall of the cavity through a round shaft. In the prior art, the adjustment can only be achieved by moving the middle shaping rod. Such a structure is inconvenient for wiring during design, and at the same time, if the middle position is adjusted too much, it may affect the opening and closing of the hair curler. Content of the Utility Model

[0004] In view of the above technical problems, the utility model discloses a hair curler with adjustable diameter, which includes an upper clamping plate and a lower clamping plate. The tails of the upper clamping plate and the lower clamping plate are hinged. A first heating rod is connected to the upper clamping plate. It is characterized in that the lower clamping plate is provided with a groove and a shaping rod, and a lifting assembly is installed in the lower clamping plate. A first fitting groove is installed in the groove. The lifting assembly drives the first fitting groove to lift and lower, and fits with the first heating rod. Through the above technical solution, the hair passes through the upper side of the shaping rod between the first fitting groove and the first heating rod. By lifting and lowering the first fitting groove, the bending degree of the curled hair can be adjusted to create different shapes. And during the adjustment process, the shaping rod can be kept stationary, reducing the difficulty of connecting the wires of the shaping rod and preventing problems caused by the lifting and lowering of the shaping rod affecting the connection wires.

[0005] Further, a second heating rod is also installed on the upper clamping plate. A second fitting groove is installed in the groove in a liftable manner. A synchronous plate is fixedly installed between the first fitting groove and the second fitting groove. The shaping rod is located between the first fitting groove and the second fitting groove. The second heating rod is in contact with the second fitting groove. Through the above technical solution, by arranging the first heating rod and the second heating rod to clamp the hair respectively, more bends can be generated in the hair, improving the efficiency of curling the hair.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0032] As Figures 1 - 13 shown, a hair curler with adjustable diameter includes an upper clamping plate 1 and a lower clamping plate 2. The tails of the upper clamping plate 1 and the lower clamping plate 2 are hinged. The tail of the lower clamping plate 2 is fixedly equipped with a connecting shaft 19, and the upper clamping plate 1 is rotatably mounted on the connecting shaft 19. A return spring 18 is fixedly mounted on the upper clamping plate 1, and the return spring 18 is fixedly connected to the lower clamping plate 2. The return spring 18 is located near the connecting shaft 19. Both the lower clamping plate 2 and the upper clamping plate 1 have short insertion rods, and the return spring 18 is inserted into the insertion rods for fixation. In the natural state, the upper clamping plate 1 and the lower clamping plate 2 maintain a certain angle. By pinching with the hand, the upper clamping plate 1 and the lower clamping plate 2 are brought closer, and after releasing the hand, they can automatically spring back. The tail of the lower clamping plate 2 is connected to an electric wire 3 for power supply. A switch and a control circuit are provided on the upper clamping plate 1 for controlling the temperature.

[0033] In this embodiment, a first heating rod 4 and a second heating rod 5 are connected to the upper clamping plate 1. A groove 7 is provided at the end of the lower clamping plate 2. Two fixing blocks 20 are fixedly installed at the middle position inside the groove 7. A shaping rod 8 is fixedly installed between the two fixing blocks 20, forming a U-shaped groove at the end of the lower clamping plate 2. A space is left between the lower side of the shaping rod 8 and the lower clamping plate 2, and a lifting assembly is installed in the space. Synchronous plates 37 are slidably installed up and down on both sides of the fixing blocks 20. A first fitting groove 21 and a second fitting groove 22 are fixedly installed on the synchronous plates 37. The first fitting groove 21 and the second fitting groove 22 are respectively located on both sides of the shaping rod 8. Driven by the lifting assembly, the synchronous plates 37, the first fitting groove 21, and the second fitting groove 22 can be lifted. The upper sides of the first fitting groove 21 and the second fitting groove 22 are both arc-shaped surfaces, and the first fitting groove 21 can be fitted with the first heating rod 4, and the second fitting groove 22 can be fitted with the second heating rod 5. The hair passes through the space between the first fitting groove 21 and the first heating rod 4 above the shaping rod 8. By lifting the first fitting groove 21, the bending degree of the curly hair can be adjusted to create different styles. And during the adjustment process, the shaping rod 8 can be kept stationary, reducing the wiring difficulty and preventing the problem that the connection wires are affected by the lifting of the shaping rod 8. Setting the first heating rod 4 and the second heating rod 5 to clamp the hair respectively can make the hair generate more bends and improve the efficiency of curling the hair.

[0034] In this embodiment, the lifting assembly includes a first fixing block 24 and a second fixing block 28. The first fixing block 24 and the second fixing block 28 are fixedly installed inside the lower clamping plate 2 and are located in the space below the shaping rod 8. A long shaft 26 is rotatably installed on the first fixing block 24. A first gear 25 and a second gear 27 are fixedly installed on the long shaft 26. A rack 23 is installed on one side of the first fitting groove 21 or the second fitting groove 22 close to the long shaft 26. The rack 23 meshes with the first gear 25. In this embodiment, the rack 23 is installed on the first fitting groove 21.

[0035] In this embodiment, an annular plate 29 is fixedly installed at the end of the lower clamping plate 2. A rotating wheel 36 is rotatably installed on the annular plate 29. A fixed shaft 30 is fixedly installed on the axis of the rotating wheel 36, and the fixed shaft 30 is coaxially fixed with the long shaft 26. A limit disk 31 is fixedly installed inside the annular plate 29. Two short rods are arranged on the limit disk 31. Two positioning holes are arranged inside the annular plate 29, and the short rods are inserted into the positioning holes for positioning and fixing. A plurality of limit slots 32 are arranged at the eccentric position of the limit disk 31. In this embodiment, there are four, that is, the rotating wheel 36 can drive the first fitting groove 21 and the second fitting groove 22 to rise four gears and be fixed. A cover plate 33 is fixedly installed on the rotating wheel 36. A limit pin 34 is slidably installed on the cover plate 33. A through hole is arranged on the cover plate 33, and the limit pin 34 slides in the through hole. A limit spring 35 is fixedly installed between the limit pin 34 and the rotating wheel 36. In the natural state, the limit spring 35 drives the limit pin 34 to pass through the cover plate 33 for a short distance, and the limit pin 34 has a round head. The bottom of the limit slot 32 is also rounded. Rotating the rotating wheel 36 can make the limit pin 34 snap into different limit slots 32. When rotating forcefully, the limit slot 32 can push the limit pin 34 to compress the limit spring 35 and leave the limit slot 32. Manually rotating the rotating wheel 36 can drive the first fitting groove 21 and the second fitting groove 22 to rise and fall simultaneously through the first gear 25, meeting the needs of different sizes of curly hair. The limit pin 34 snapping into different limit slots 32 makes the first gear 25 rotate different degrees, which can control the first fitting groove 21 and the second fitting groove 22 to rise different distances, and can make the first fitting groove 21 and the second fitting groove 22 maintain their positions to prevent changes during use.

[0036] In this embodiment, a clamping groove 6 is arranged on the lower clamping plate 2. A clamping hook 17 is slidably installed in the clamping groove 6. A connecting plate 16 is fixedly installed on the lower side of the clamping hook 17. A push-pull block 10 is fixedly installed on the lower side of the connecting plate 16. A clamping rod 9 is installed on the upper clamping plate 1. The clamping rod 9 is inserted into the clamping groove 6 and cooperates with the clamping hook 17 for fixation. A clamping head 14 is fixedly installed on the connecting plate 16. A first clamping cylinder 12 and a second clamping cylinder 13 are fixedly installed inside the lower clamping plate 2. The clamping head 14 has elasticity. When the clamping head 14 is clamped between the first clamping cylinder 12 and the second clamping cylinder 13, the clamping rod 9 is fixed by the clamping hook 17. When unlocking is required, manually slide the push-pull block 10 to drive the connecting plate 16 to move the clamping head 14 away from the clamping rod 9. At this time, the clamping hook 17 no longer hooks the clamping rod 9, and the upper clamping plate 1 and the lower clamping plate 2 can also be separated and used normally.

[0037] Working principle: First, slide the push-pull block 10 to drive the connecting plate 16, causing the clamping joint 14 to move away from the clamping rod 9. At this time, the clamping hook 17 no longer hooks the clamping rod 9, and the upper clamping plate 1 and the lower clamping plate 2 can also be separated and used normally. Rotate the rotating wheel 36 according to requirements. The rotating wheel 36 drives the cover plate 33 and the limit pin 34 to move. The limit pin 34 switches into different limit grooves 32 for fixation. During the process, the rotating wheel 36 drives the long shaft 26 to rotate through the fixed shaft 30. The long shaft 26 drives the first gear 25 and the second gear 27 to rotate. The engaged rack 23 drives the first fitting groove 21 and the second fitting groove 22 to rise and adjust, and finally fix. After the adjustment is completed, turn on the switch to adjust the temperature, and then curl the hair.
