[0002] In people's daily life, combs can be seen everywhere. They are commonly used consumer goods in people's daily life.

[0003] At present, a comb is mainly composed of a comb head and a comb handle. The tail of the comb head and the head of the comb handle are connected together, and the connection can be a detachable connection or an integrated connection. When the detachable connection is made, the comb head and the comb handle can be disassembled and assembled, thereby meeting the user's need to flexibly replace the corresponding comb head according to actual needs.

[0004] For example, in a hot air comb that is easy to replace the comb head disclosed in Chinese Patent Application No. 202321596123.7, although the comb head and the handle body can be detachably assembled, the locking between the comb head and the handle body is achieved by the limit groove provided on the comb head and the limit block and spring assembled on the handle body. Therefore, when the comb head and the handle body are disassembled, the operator needs to make the limit block move to overcome the spring elastic force, and the comb head can be separated from the handle body only after the limit block slides out of the limit groove. Therefore, the hot air comb that is easy to replace the comb head disclosed in Chinese Patent Application No. 202321596123.7 has the defects of troublesome disassembly operation and high cost.

[0005] Therefore, there is an urgent need for a detachable comb to overcome one or more of the above-mentioned defects. Utility Model Content

[0024] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the embodiments and the accompanying drawings.

[0025] See also Figures 1 to 3 The detachable comb 100 of the utility model comprises a comb 10, a comb handle 20 and a screw-on structure 30 disposed between the tail 11 of the comb 10 and the head 21 of the comb handle 20. The tail 11 of the comb 10 and the head 21 of the comb handle 20 are plugged into each other to facilitate the quick docking operation between the comb 10 and the comb handle 20.

[0026] The turn-lock structure 30 includes a first guide groove 31 extending along the insertion direction of the comb head 10 and the comb handle 20, a second guide groove 32 connected to the first guide groove 31, a blocking protrusion 33 protruding in the second guide groove 32, and a protrusion 34 that can slide along the first guide groove 31 and the second guide groove 32. Figure 2 , Figure 3 , Figure 5 and Figure 6 As an example, the convex head 34 is a fan-shaped structure, so that the outer side of the convex head 34 is a cylindrical surface, which effectively reduces the friction resistance between the convex head 34 and the blocking convex 33, so that the convex head 34 can pass over the blocking convex 33 more smoothly; obviously, according to actual needs, the convex head 34 can also be a structure of other shapes, so it is not Figure 2 , Figure 3 , Figure 5 and Figure 6 Limits shown.

[0027] At the same time, the second guide groove 32 extends in an arc shape around a rotation center line C, and the rotation center line C extends along the insertion direction. Figure 5 and Figure 6 As an example, the center line of the comb handle 20, the center line of the comb head 10 and the rotation center line C coincide with each other, so that the relative rotation between the comb handle 20 and the comb head 10 is also performed around the rotation center line C, thereby satisfying the need for the protrusion 34 to rotate into or out of the second guide groove 32 around the rotation center line C during the relative rotation between the comb handle 20 and the comb head 10.

[0028] Furthermore, the protrusion 34 can slide along the first guide groove 31 to an alignment position aligned with the second guide groove 32 during the insertion of the comb head 10 and the comb handle 20. Figure 6 As shown, the convex head 34 in the aligned position can be rotated around the rotation center line C to the locking position of the second guide groove 32 passing over the blocking convex 33, as shown in FIG. Figure 5As shown, at this time, the blocking protrusion 33 can prevent the protrusion 34 from rotating out of the second guide groove 32 around the rotation center line C, thereby achieving the purpose of stabilizing the comb head 10 and the comb handle 20. Figure 5 and Figure 6 As an example, there are two rotating buckle structures 30, which are arranged relative to each other with the rotation center line C as the center. For example, the central angle between the two rotating buckle structures 30 is 180 degrees. This design can increase the stability of the comb head 10 and the comb handle 20 after assembly. Obviously, according to actual needs, the number of rotating buckle structures 30 can also be one or three. Figure 5 and Figure 6 More specifically, as follows:

[0029] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, as an example, the blocking protrusion 33 is also arranged adjacent to the first guide groove 31, so that the design can effectively reduce the length of the arc-shaped extension of the second guide groove 32. In addition, the blocking protrusion 33 is also arranged to extend along the insertion direction, and the cross section of the blocking protrusion 33 is an arc. Figure 5 and Figure 6 As shown, it is more convenient for the convex head 34 to cross the blocking convex 33; obviously, according to actual needs, the cross section of the blocking convex 33 can also be a trapezoid, so it is not necessary to Figure 5 and Figure 6 Limits shown.

[0030] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, as an example, the tail 11 of the comb head 10 is a hollow columnar structure, the head 21 of the comb handle 20 is a barrel structure, the first guide groove 31 and the second guide groove 32 are formed on the inner side wall 211 of the barrel structure, the blocking protrusion 33 is formed on the inner side wall 211 of the barrel structure, and the protrusion 34 is formed on the outer side wall 111 of the column structure, so as to facilitate the relative rotation of the tail 11 of the comb head 10 and the head 21 of the comb handle 20 around the rotation center line C, and improve the reliability of the matching between the tail 11 of the comb head 10 and the head 21 of the comb handle 20. Specifically, Figure 5 and Figure 6 As an example, the cross-sectional outer contour 112 of the column structure is circular, and the cross-sectional inner contour 212 of the barrel structure is circular. The column structure and the barrel structure are matched with each other in a clearance, so as to make the column structure and the barrel structure more compact while ensuring the smoothness of rotation. Obviously, according to actual needs, the cross-sectional outer contour 112 of the column structure can also be an ellipse or a regular polygon, which can also ensure that the tail 11 of the comb head 10 and the head 21 of the comb handle 20 can rotate with each other. It should be noted that although Figure 2and Figure 3 The tail 11 of the comb head 10 is a columnar structure and the head 21 of the comb handle 20 is a tubular structure; of course, according to actual needs, the tail 11 of the comb head 10 can also be a tubular structure and the head 21 of the comb handle 20 can be a columnar structure, and the columnar structure can also be solid. Figure 2 , Figure 3 , Figure 5 and Figure 6 Limits shown.

[0031] like Figure 3 As shown, the detachable comb 100 of the present invention further includes an indication structure 40, and the indication structure 40 includes a locking state indication position 41, a release state indication position 42, and an indication head 43. The locking state indication position 41 and the release state indication position 42 are both arranged at the head 21 of the comb handle 20, and the locking state indication position 41 and the release state indication position 42 are also exposed to the outside. The indication head 43 is arranged at the tail 11 of the comb 10, and the indication head 43 is also exposed to the outside; when the indication head 43 is in the locking position, it is aligned with the locking state indication position 41 to remind the user that the detachable comb 100 of the present invention is in the locking state; when the indication head 43 is in the alignment position, it is aligned with the release state indication position 42 to remind the user that the detachable comb 100 of the present invention is in the release state. In addition, the comb 10 is a flat comb. It should be noted that although Figure 3 It is shown that both the locking state indicating position 41 and the unlocking state indicating position 42 are arranged at the head 21 of the comb handle 20, and the indicating head 42 is arranged at the tail 11 of the comb head 10; obviously, according to actual needs, both the locking state indicating position 41 and the unlocking state indicating position 42 can be arranged at the tail 11 of the comb head 10, and correspondingly, the indicating head 42 is arranged at the head 21 of the comb handle 20. In addition, since the protruding head 34 rotates into the locking position or rotates out of the locking position and rotates to the alignment position by rotating around the rotation center line C, the locking state indicating position 41 and the unlocking state indicating position 42 are arranged in a spaced relationship along the rotation direction of the protruding head 34 around the rotation center line C; and since the power for the protruding head 34 to rotate around the rotation center line C is realized by the relative rotation between the comb head 10 and the comb handle 20 around the rotation center line C.

[0032] Compared with the prior art, the screw-lock structure 30 provided between the tail 11 of the comb head 10 and the head 21 of the comb handle 20 includes a first guide groove 31 extending along the insertion direction, a second guide groove 32 connected to the first guide groove 31, a blocking protrusion 33 convexly provided in the second guide groove 32, and a protrusion 34 that can slide along the first guide groove 31 and the second guide groove 32, and the second guide groove 32 extends in an arc shape around a rotation center line C extending along the insertion direction; therefore, during the assembly process of the comb head 10 and the comb handle 20, the comb head 10 and the comb handle 20 are inserted into each other when the protrusion 34 is aligned with the first guide groove 31, and the protrusion 34 slides along the first guide groove 31 to an alignment position aligned with the second guide groove 32 during the insertion process, and the state is shown in FIG. Figure 6 As shown; at this time, the convex head 34 in the aligned position is rotated around the rotation center line C to the locking position of the second guide groove 32 passing over the blocking convex 33, and the blocking convex 33 can prevent the convex head 34 from rotating out of the second guide groove 32 around the rotation center line C, so as to ensure the stability of the comb head 10 and the comb handle 20 after assembly; similarly, when the comb head 10 and the comb handle 20 are disassembled, the convex head 34 is made to pass over the blocking convex 33 around the rotation center line C and enter the first guide groove 31, and at this time, the comb head 10 and the comb handle 20 are relatively pulled out, so that the purpose of disassembling the comb head 10 and the comb handle 20 can be achieved. Therefore, the detachable comb head 100 of the utility model is convenient for the assembly and disassembly operation between the comb head 10 and the comb handle 20, ensures the assembly stability between the comb head 10 and the comb handle 20, and can also reduce costs.

[0033] It should be noted that the direction indicated by arrow A in the drawings is the direction in which the head 21 of the comb handle 20 is inserted into the tail 11 of the comb head 10, and correspondingly, the opposite direction indicated by arrow A in the drawings is the direction in which the tail 11 of the comb head 10 is inserted into the head 21 of the comb handle 20; therefore, the opposite insertion directions of the tail 11 of the comb head 10 and the head 21 of the comb handle 20 are the direction indicated by arrow A and the opposite direction. In addition, since the convex head 34 needs to cross the blocking convex 33 when switching between the alignment position and the locking position, it is necessary to control the size of the radially overlapping portion of the convex head 34 and the blocking convex 33. This size is flexibly designed by those skilled in the art based on the present application according to actual needs, so it will not be repeated here.

[0034] The above disclosure is only a preferred example of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
