Description

Hair straightener

Technical Field

The utility model relates to a hair-dressing instrument technical field, more specifically says that it relates to a hair straightener.

Background

The hair straightener is called an electric splint and a popular splint, the common hair straightener is of a V-shaped structure and comprises an upper long splint and a lower long splint which are arranged in a V shape, one ends of the two splints are hinged together through a lock shaft, the other ends of the two splints can be opened and closed mutually, and a pair of heating plates is correspondingly arranged on the opposite inner side surfaces of the opening and closing ends of the two splints.

Generally, a hair straightener includes an upper plate and a lower plate having heating elements at their heads and pivotally connected at their ends to each other, and a connecting head assembled to the upper plate and the lower plate and having ends connected to an external power supply harness. When the hair straightener is used, an opening structure is usually arranged to automatically open the upper splint and the lower splint and put hair between the upper splint and the lower splint for hairdressing; but the space occupied by the opened state is large, and the storage is very inconvenient; the hair straightener in the prior art is generally provided with an opening and closing lock, and the opening and closing of the clamping plate are controlled through structures such as the clamping hook and the clamping groove, but the hinged shaft of the hair straightener is generally positioned at the tail end, so the structures such as the clamping hook and the clamping groove can be positioned at the position of a lever which is hard to force, and the problem that the clamping hook cannot be locked due to the breakage of the clamping hook is easily caused; simultaneously prior art is tight with the punch holder from top to bottom, and in view of safety, generally be provided with the gap for the heating plate can not laminate, and this results in when the less region of volume of sending out of centre gripping such as bang when using, and the hair can not be pressed from both sides easily, and it is very inconvenient to use.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a hair straightener which has the advantages of lockable upper and lower clamping plates, simple and reliable locking structure, and the like; when in use, the heating sheet can be tightly attached, and can play a good clamping effect on a small amount of hair.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a hair straightener, includes punch holder and lower plate, the punch holder is provided with the locking structure with the one end of lower plate, be provided with rather than sliding connection's articulated shaft in the locking structure, the punch holder is articulated through articulated shaft with the lower plate, be provided with the torsional spring in the articulated shaft, the structural symmetry that goes back of locking is provided with the arc concave surface, the terminal surface phase-match of arc concave surface and punch holder and lower plate, still be provided with spacing lug in the arc concave surface, still be provided with on punch holder and the lower plate and block the strip with spacing lug assorted, the structural spacing safety piece that still is provided with of locking, spacing safety piece stretches into between punch holder and the lower plate, still be provided with on punch holder and the lower plate with spacing safety piece assorted stopper.

Through adopting above-mentioned technical scheme, push-and-pull to the locking structure, can realize locking and separation between the punch holder and the lower plate, and the locking structure is integrated structure, and the power that receives is the inside pressure of punch holder and lower plate, can bear bigger power and not fragile, and the locking is more firm.

The utility model discloses further set up to: the cross-section of spacing safety block is the toper, the cross-section of stopper is the right trapezoid structure, and its inclined plane matches with the conical surface of spacing safety block.

By adopting the technical scheme, when the locking structure is pushed inwards, the limiting safety block can extrude the limiting block to two sides along the inclined plane, so that the heating sheets on the upper clamping plate and the lower clamping plate can not be attached to each other but remain a part of gaps.

The utility model discloses further set up to: the heating plate is arranged on the upper clamping plate and the lower clamping plate, and springs are abutted between the heating plate and the inner walls of the upper clamping plate and the lower clamping plate.

Through adopting above-mentioned technical scheme, can let the heating plate have certain flexible ability when the more hair of centre gripping.

The utility model discloses further set up to: the heating plate is characterized in that a control knob is further arranged on the lower clamping plate and electrically connected with the heating plate, and a groove matched with the control knob is further formed in the upper clamping plate.

The utility model discloses further set up to: still be provided with the power supply line in the locking structure, the power supply line is connected with control knob and heating plate electricity.

The utility model discloses further set up to: the locking structure is also provided with an elastic strip which is matched with the blocking piece; and anti-skid stripes are arranged at the far ends of the upper clamping plate and the lower clamping plate relative to the locking structure.

The utility model discloses further set up to: the inner walls of two sides of the locking structure are provided with long circular hole grooves, and the hinged shaft slides in the long circular hole grooves.

To sum up, the utility model discloses following beneficial effect has:

compared with the prior art, the utility model is provided with the locking structure and the limiting safety block, when the utility model is pushed inwards through the position of the sliding locking structure, the blocking strip can be blocked with the surface of the locking structure, so that the upper clamping plate and the lower clamping plate can not rotate around the hinge shaft and can not be opened, when the locking structure is pulled outwards, the stop strip is not stopped by the surface of the locking structure any more, the torsion spring arranged on the articulated shaft releases energy to drive the upper clamping plate and the lower clamping plate to rotate, the stop strip can rotate along the arc concave surface, the stop strip is stopped by the limiting convex block after rotating for a certain angle, the open angle is restrained, and the opening and closing of the upper clamping plate and the lower clamping plate are controlled by the push-pull locking structure, although the locking structure is still a labor-consuming lever, the locking structure is of a one-body structure, pressure rather than tension is borne by the locking structure, the locking structure is firmer and less prone to damage, and the problem that locking cannot be achieved due to the fact that clamping hooks and clamping grooves are prone to being broken in the prior art is solved; simultaneously, the last spacing safety block that still is provided with of locking structure, when locking structure inwards pushes away, spacing safety block can block in last spacing block department, make the upper and lower splint can not paste together with the heating plate on it, guarantee safety, and when locking structure outwards pull the back, spacing safety block no longer with last spacing block cooperation, make the upper and lower splint can laminate each other with the heating plate on it, can also play tight effect to less volume of sending out, when having solved among the prior art centre gripping for example the less region of volume of sending out such as bang, can not press from both sides the hair easily, use very inconvenient problem.
