Technical Field

The invention relates to a hair comb, in particular to a hair comb capable of preventing hair from being pulled and injured.

Background

With the increasing demand of people for beauty and hairdressing, various hair combs, such as curling combs, dyeing combs, electric combs, etc., have been developed for the convenience of hairdressing. However, the hair comb with controllable tension and no damage to scalp and hair is commonly pursued by people.

For example, chinese patent No. CN200320109059.1 (publication No. CN2659213Y) discloses "a comb", which includes a cylindrical comb body and a comb handle connected with the comb body into a whole, wherein the circumferential surface of the comb body is provided with radially outwardly extending comb teeth, the circumferential surface of the comb body is further divided into longitudinal grooves, and a cylindrical tube parallel to the comb body is partially embedded in the longitudinal grooves and is rotatably connected with the comb body. When in combing, the cylindrical barrel is contacted with the hair, and the friction force is generated between the cylindrical barrel and the hair to push the cylindrical barrel and the comb body to rotate mutually, so that the resistance between the hair and the comb is reduced, and the smooth combing is ensured without breaking the hair.

The comb disclosed above needs to be in direct contact with hair through the cylindrical barrel, and generates friction force with the hair to push the cylindrical barrel and the comb body to rotate mutually, so that the resistance between the hair and the comb is reduced, and the hair is prevented from being pulled apart due to overlarge tension. Therefore, the phenomenon that the hair is directly contacted through the cylindrical barrel when the pulling force is too large is avoided, but the friction force between the outer circumference of the cylindrical barrel and the hair is very small in practical use, and the cylindrical barrel and the comb body cannot be pushed to rotate mutually under most conditions, so that smooth combing cannot be realized, hair is broken, and hair roots are torn;

disclosure of Invention

The first technical problem to be solved by the invention is to provide a hair comb which can automatically slip when being used under the condition of overlarge pulling force so as to avoid pulling hair, aiming at the problems existing in the prior art.

A second technical problem to be solved by the present invention is to provide a comb in which the movable setting of the maximum resistance value is adjustable.

The technical scheme adopted by the invention for solving the first technical problem is as follows: the comb comprises a comb handle, a comb tooth sleeve positioned in front of the comb handle and comb teeth arranged on the periphery of the comb tooth sleeve, and is characterized in that a locking and releasing mechanism capable of enabling the comb tooth sleeve and the comb handle to be rotatably connected is further arranged in the comb tooth sleeve, and when the external force is smaller than the set maximum resistance value, the transmission connection between the comb tooth sleeve and the comb handle is locked by the locking and releasing mechanism; and when the external force is larger than the set maximum resistance value, the locking and releasing mechanism releases the transmission connection between the comb tooth sleeve and the comb handle.

That is, when the external force is larger than the set maximum resistance value, the comb teeth sleeve can rotate relative to the comb handle, so that when the comb is used in practice and the force is too large or the hair is knotted seriously, the locking and releasing mechanism can release the locking between the comb teeth sleeve and the comb handle, and the comb teeth sleeve can rotate relative to the comb handle, thereby avoiding the damage to the hair and the hair roots.

Wherein, the set maximum resistance value is the force which can remove the transmission connection between the comb teeth sleeve and the comb handle, so that the comb teeth sleeve and the comb handle can rotate mutually without interference, the locking and releasing mechanism has the function of preventing the comb teeth sleeve and the comb handle from being locked, and the external force is the force acting on the comb teeth sleeve or the comb handle.

As an improvement, the radial hole is a through hole, the two ejector blocks are respectively positioned at two ends of the radial hole, the compression spring is positioned between the two ejector blocks, and two ends of the compression spring are respectively abutted against the tail ends of the two ejector blocks. So set up, enable kicking block more stably keep the state of contradicting with the broach cover.

Furthermore, on the basis that the radial hole is a through hole, the two ejector blocks are respectively positioned at two ends of the radial hole, the two compression springs are respectively corresponding to the two ejector blocks, two adjacent support blocks are arranged between the two compression springs, and two ends of each compression spring respectively abut against the corresponding ejector block and support block. So, two compression spring act on the kicking block respectively, make the state that the kicking block can be better keeps conflicting with the broach cover.

Furthermore, the end faces of the top block and the supporting block, which correspond to the compression springs, are respectively provided with an annular groove for inserting the end of the corresponding compression spring.

Preferably, the comb tooth sleeve is provided with an axial round hole, a core column which can rotate relative to the comb tooth sleeve is arranged in the hole, the core column is detachably connected with the comb handle, an end cover with the same diameter as the core column is fixedly arranged at one end, close to the core column, of the comb handle, a radial cylinder is fixedly arranged on the end face, far away from the comb handle, of the end cover, a radial through hole is formed in the cylinder, the two top blocks are respectively arranged at two ends of the radial through hole, the elastic piece is a compression spring and is provided with two supporting blocks which respectively correspond to the two top blocks, two supporting blocks which are adjacently arranged are arranged between the two compression springs, and two ends of each compression spring respectively abut against the corresponding top block and the corresponding supporting block.

As an improvement, a limiting block is arranged between two adjacent supporting blocks on the hole wall of the radial through hole.
