Description

Technical Field

[0001] The utility model relates to the technical field of hair cutting tools, in particular to a hair cutting device. Background Art

[0002] An electric hair clipper is mainly composed of a hair clipper body and a movable cutter head. The movable cutter head is powered by the hair clipper body and trims hair. Currently, the trimming length of the movable cutter head is adjusted by clamping a fixed cutter head on the movable cutter head and replacing the fixed cutter heads of different sizes. However, the clamping method of detachably replacing the fixed cutter head is inconvenient for manual operation, which is not conducive to convenient adjustment of the hair trimming length of the hair clipper. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a hair clipper, which solves the problem that the existing hair clippers are inconvenient for trimming the hair length.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a hair clipper, including a body and a fixed blade head slidably arranged on the body, and the hair clipper also includes:

[0005] An operating assembly is rotatably connected to the machine body and connected to the fixed blade head so as to drive the fixed blade head to move on the machine body when the operating assembly rotates;

[0006] A connecting assembly, through which the operating assembly is rotatably connected to the fuselage;

[0007] The elastic locking part is elastically loaded between the connecting component and the operating component, so that when the operating component rotates, the elastic locking part is elastically deformed to allow the operating component to rotate, and when the operating component stops rotating, the elastic locking part is reset to lock the operating component relative to the fuselage.

[0008] Furthermore, an assembly hole is provided on the operating component, one end of the connecting component is embedded in the assembly hole, and the other end passes through the assembly hole and is connected to the fuselage.

[0009] By adopting the above technical solution, the assembly hole is set, which makes it easy to integrate the connector on the operating component. At the same time, through the assembly hole setting, part of the connecting component can also be hidden, thereby improving the integration of the product.

[0010] Furthermore, the connecting component includes a stopper and a fastener, the fastener passes through the stopper and is connected to the fuselage, an anti-rotation structure is provided between the stopper and the fuselage to keep the stopper stationary when the operating component rotates around the fastener as the rotation center, and an elastic locking portion is provided on the stopper, and its free end elastically abuts against the inner wall of the assembly hole.

[0011] By adopting the above technical solution, the anti-rotation structure can make the elastic locking part on the anti-rotation part remain stationary when the operating component rotates, so that when the operating component rotates, the inner wall of the assembly hole is always elastically clamped by the elastic locking part, and then after the operating component rotates to any angle and stops, the elastic locking part can be used to clamp the assembly hole to achieve locking of the position of the operating component after rotation.

[0012] Furthermore, the anti-rotation part includes a mounting head for setting an elastic locking part and a anti-rotation column arranged at one end of the mounting head. A anti-rotation hole is provided on the fuselage for limiting the rotation of the anti-rotation column when cooperating with the anti-rotation column. The anti-rotation hole and the anti-rotation column are plugged into each other to form an anti-rotation structure.

[0013] By adopting the above technical solution, the anti-rotation hole can be a non-circular special-shaped hole, and its shape can be a special-shaped hole, a polygonal prism hole or other shapes. Its main function is to limit the rotation of the entire anti-rotation part after the anti-rotation column is inserted.

[0014] Furthermore, a gear ring is provided on the inner wall of the assembly hole, and the free end of the elastic locking portion elastically abuts against the gear ring.

[0015] By adopting the above technical scheme, the free end of the elastic locking part is abutted against the gear ring, so that when the gear ring rotates with the operating component, the free end of the elastic locking part will abut against the gear ring, and when the free end of the elastic locking part abuts against the teeth, the elastic locking part is compressed, and when its free end enters the tooth groove between two teeth, the elastic locking part elastically resets and enters the tooth groove, so that when the operating component rotates, the free end of the elastic locking part will elastically abut against the gear ring, thereby emitting a "click" mechanical impact sound, thereby improving the user experience and making the manual adjustment feel better. At the same time, when the free end of the elastic locking part enters the tooth groove, the operating component can also be locked, so that after the manual rotational external force applied to the operating component is canceled, the operating component can also be stably locked in the predetermined rotation position, thereby positioning the fixed blade head in the adjusted position.

[0016] Furthermore, the anti-rotation member is provided with a through hole along its axis for the fastener to pass through.

[0017] By adopting the above technical solution, the provision of the through hole makes it easy for the fastener to pass through the anti-rotation member, so as to facilitate the convenient assembly of the two, while saving the assembly space of the two, so that the volume of the component after the two are combined is more compact.

[0018] Furthermore, the operating assembly includes a knob head and a handle arranged on the rotating head, and the assembly hole is correspondingly opened on the rotating head.

[0019] By adopting the above technical solution, the setting of the rotating head makes it convenient to set the connecting component and the elastic locking part, and the handle is for the length of the force arm, and manual adjustment of the operating component is more labor-saving and easy when rotating.

[0020] Furthermore, a dial head is provided on one end face of the rotating head away from the center of the circle, and a slot is provided on the fixed blade head. When the operating assembly is connected to the body, the dial head is correspondingly embedded in the slot.

[0021] By adopting the above technical solution, the dial head is inserted into the slot, and when the rotating head rotates around the fastener, it can push the fixed cutter head to move through the dial head, thereby converting the rotational motion of the rotating head into the linear motion of the fixed cutter head.

[0022] Furthermore, a sliding mechanism is provided between the fixed blade head and the machine body to guide the fixed blade head to perform linear reciprocating motion on the machine body when the fixed blade head rotates in the operating assembly.

[0023] By adopting the above technical solution and setting the sliding mechanism, it is convenient for the fixed blade head to linearly reciprocate along the length direction of the machine body under the rotation drive of the operating component, so as to facilitate the adjustment of the setting position of the fixed blade head.

[0024] Furthermore, the elastic locking portion includes an elastic sheet or a spring plunger.

[0025] By adopting the above technical solution, the spring plunger and the elastic sheet both have the characteristics of elastic retractable reset, so that after the rotation of the operating component stops, the operating component can be tightly locked by the elastic locking part after elastic reset.

[0026] Compared with the prior art, the advantages of the utility model are:

[0027] 1. In the utility model, the operating component is rotatably connected to the machine body through the connecting component, and after being connected with the fixed blade head, the setting position of the fixed blade head on the machine body is adjusted by rotating the operating component. At the same time, an elastic locking portion is provided between the connecting component and the operating component, and the elastic squeezing effect of the elastic locking portion is utilized to maintain a certain elastic damping between the operating component and the connecting component. In this way, when the operating component is rotated to adjust the fixed blade head, the elastic force can be utilized to make the operating component rotate to any angle and can be stably positioned at any position, so that the precise position of the fixed blade head on the machine body can be adjusted conveniently, which greatly improves the convenience of personnel in adjusting the position of the fixed blade head.

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0043] Reference Figure 1 and 2The hair clipper includes a body 1, a movable blade head 8 and a fixed blade head 5. The movable blade head is arranged on the body 1 and connected to a power unit in the body 1. The movable blade head 8 moves under the drive of the power unit to trim the hair. The fixed blade head 5 is covered on the outside of the movable blade head 8. The fixed blade head 5 moves linearly on the body 1, and then the relative position of the fixed blade head 5 and the movable blade head 8 can be changed, so as to achieve the adjustment of the trimmed hair length of the hair clipper. The hair clipper is provided with an operating component 3, a connecting component and an elastic locking portion. The operating component 3 is rotatably connected to the side of the body 1 through the connecting component, and the operating component 3 is connected to the movable blade head 8. The fixed blade head 5 can be driven to set a position on the body 1 through the rotation of the operating component 3. An elastic locking portion is provided between the connecting component and the operating component 3. The locking portion is elastically loaded between the connecting component and the operating component 3, so that the operating component 3 and the connecting component are tightened through its elastic action, thereby making the operating component 3 have a certain elastic damping when rotating, so that when the operating component 3 is rotated by an external force, its elastic locking portion can be elastically contracted to allow the operating component 3 to rotate, and the position of the fixed blade head 5 is adjusted. When the external force is removed, the elastic locking portion is elastically reset, and the rotation of the operating component 3 is elastically damped, thereby preventing the operating component 3 from rotating arbitrarily, thereby achieving the purpose of positioning the fixed blade head 5 after displacement. Through the above scheme, the setting position of the fixed blade head 5 on the body 1 can be conveniently adjusted to facilitate the hair clipper to accurately control the moving blade head 8 to trim the hair.

[0044] Reference Figure 3 and 4 The operating assembly 3 includes a rotating head 31 and a handle 32 arranged on the rotating head 31. An assembly hole 310 for accommodating the connecting assembly is opened on one side of the rotating head 31. The connecting assembly includes a stopper 2 and a fastener 7. After the fastener 7 passes through the stopper 2, one end of the fastener 7 passes through the side of the rotating head 31 away from the assembly hole 310 and is connected to the fuselage 1. One end of the elastic locking portion is arranged on the stopper 2. An anti-rotation structure is arranged between the stopper 2 and the fuselage 1. The anti-rotation structure can prevent the rotating head 31 from rotating around the fastener 7 as the rotation center. The holding member 2 and the elastic locking portion will not rotate with the rotation of the rotating head 31. The other end (i.e., the free end) of the elastic locking portion elastically abuts against the inner wall of the assembly hole 310. In this way, the elastic force of the elastic locking portion can be used to make the rotation of the operating component 3 around the fastener 7 have a certain damping, so that after the rotating head 31 is rotated to adjust the position of the fixed knife head 5, even if the rotational driving force of the rotating head 31 is canceled, the operating component 3 can be stabilized on the fuselage 1, thereby making the fixed knife head 5 stably locked.

[0045] In this embodiment, refer to Figure 4The fastener 7 can be a screw, and its first end connected to the fuselage 1 is provided with a thread, and the second end is provided with a nut. When the screw passes through the stop member 2, its nut is tightly pressed against the first end of the stop member 2, and then the second end of the fastener 7 passes through the rotating head 31 and is screwed to the corresponding threaded hole provided on the fuselage 1, thereby realizing the connection between the fastener 7, the stop member 2 and the rotating head 31 after assembly with the fuselage 1.

[0046] In this embodiment, a through hole communicating with the assembly hole 310 is provided at the center of one side of the rotating head 31 away from the assembly hole 310 , so that a screw can pass through the rotating head 31 and connect with the body 1 .

[0047] In this embodiment, refer to Figure 4 As an embodiment of the anti-rotation structure between the stopper 2 and the fuselage 1, the stopper 2 includes a mounting head 21 and a stopper column 22 arranged at one end of the mounting head 21. The two are integrally formed or assembled in a split manner. The axes of the two are penetrated by a through hole to facilitate the screws to pass through. The shape of the mounting head 21 is adapted to the shape of the assembly hole 310 to facilitate its assembly in the assembly hole 310. The outer shape of the positioning column can be a non-circular polygonal prism, such as a quadrilateral prism, a pentagonal prism, etc., and a stopper hole 11 adapted to the shape of the stopper column 22 is correspondingly opened on the main body. When the rotating head 31 is installed on the fuselage 1 by screws, the part of the stopper column 22 protruding from the outside of the rotating head 31 is correspondingly inserted into the stopper hole 11, so that when the rotating head 31 rotates, its stopper 2 remains stationary, and the corresponding elastic locking portion also remains relatively stationary because it is arranged on the mounting head 21.

[0048] Based on the above embodiment, other structures can also be used as the anti-rotation structure between the anti-rotation member 2 and the fuselage 1. For example, the above-mentioned anti-rotation column 22 is replaced with an insertion rod arranged around one side of the mounting head 21, and the anti-rotation hole 11 is set as a socket that cooperates with the insertion rod. By inserting the insertion rod into the socket, the anti-rotation member 2 can also be prevented from rotating when the rotating head 31 rotates.

[0049] Based on the above embodiment, the elastic locking portion can be an elastic sheet or a spring plunger 4, as long as it can provide an elastic force between the rotating head 31 and the mounting head 21, so that the rotating head 31 has a certain damping when rotating, and can ensure that after the external force driving the rotating head 31 to rotate is withdrawn, the operating component 3 will not easily shake and affect the position of the fixed blade head 5. The elastic locking portion can also be other structures, such as a V-shaped metal sheet with elastic force, elastic rubber, etc. The following is a specific description of the embodiment of the existing common spring plunger 4:

[0050] The spring plunger 4 includes a ball head 41, a shell 43 and a spring 42. The shell 43 has a cavity inside, and the spring 42 is accommodated in the cavity. The ball head 41 is movably arranged in the cavity and is subjected to the elastic force of the spring 42. When the ball head 41 is compressed, the ball head 41 compresses the spring 42 so that the ball head 41 is hidden in the cavity. When the external force is removed, the ball head 41 can be elastically reset under the elastic force of the spring 42.

[0051] Based on the above embodiment, an opening 210 can be opened on the outer side of the mounting head 21, and then the shell 43 of the spring plunger 4 is embedded in the opening 210, so that the spring plunger 4 is integrated on the mounting head 21. Of course, it is conceivable that the shell 43 can be omitted, and the opening 210 is directly used to replace the cavity of the shell 43 to directly set the spring 42 and the ball head 41 in the opening 210. Of course, the assembly method between the elastic locking portion and the mounting head 21 can also be other structures and assembly methods, which will not be elaborated here.

[0052] Based on the above embodiment, in order to improve the operating feel of personnel when adjusting the rotation of the rotating head 31, and to improve the elastic damping feeling of the elastic locking portion between the connecting component and the operating component, preferably, refer to Figure 4 A gear ring 311 is provided on the inner wall of the assembly hole 310, and a plurality of teeth are arranged around the gear ring 311, and tooth grooves are formed between adjacent teeth. When a person drives the rotating head 31 to rotate by operating the handle 32, the ball head 41 of the spring plunger 4 will be squeezed by the teeth and then elastically contracted. When the ball head 41 enters the tooth groove between the two teeth, the ball head 41 is reset under the elastic force of the spring 42 to enter the tooth groove, thereby emitting a "click" mechanical impact sound, thereby improving the user's experience of use and making the manual adjustment feel better. At the same time, when the free end of the elastic locking portion enters the tooth groove, the operating component 3 can also be locked, so that after the manual rotational external force applied to the operating component 3 is canceled, the operating component 3 can also be stably locked in the predetermined rotation position, thereby positioning the fixed blade head 5 in the adjusted position.

[0053] Based on the above embodiment, the gear ring 311 is provided to improve the elastic damping of the operating component 3 and the connecting component when they rotate relative to each other, and to improve the user experience when the user operates the rotating head 31 to rotate and the stability of the fixed blade head 5 after adjustment. It can be imagined that the gear ring 311 can also be other structures, for example, the gear ring 311 can be replaced by a plurality of concave-convex structures provided on the inner wall of the assembly hole 310, such as a sandpaper layer with greater friction, etc., which can also achieve the above effect.

[0054] Based on the above embodiments, when the elastic locking part is a metal elastic sheet or other materials or structures that can contact the inner wall of the assembly hole 310 and have a certain friction resistance between the two, it is also possible not to set a gear ring 311 on the inner wall of the assembly hole 310 or replace sandpaper or other structures to increase the contact friction. Instead, the elastic force of the elastic locking part is solely relied on to tighten the connecting component and the operating component. The combination of the elastic plunger and the gear ring 311 can further optimize the product usage experience and improve the product operability.

[0055] In the above embodiment, the elastic locking portion is installed on the mounting head 21 of the stop member 2, and its free end abuts against the inner wall of the assembly hole 310. It can be imagined that the positions of the two can also be interchanged, that is, the elastic locking portion is installed on the assembly hole 310, and its free end abuts against the mounting head 21 of the stop member 2, which can also achieve the above effect.

[0056] Based on the above embodiments, refer to Figure 1 As a way of linear sliding between the fuselage 1 and the fixed blade head 5, a sliding mechanism can be set between the two. Specifically, the fixed blade head 5 includes a blade head 52 and a fixed blade holder 53. The fixed blade holder 53 and the blade head 52 can be integrally formed, or the two are fastened by screws 51. Two sliding flanges 532 are provided on both sides of the bottom of the fixed blade holder 53, and two slide grooves 12 are provided on both sides of one end of the corresponding fuselage 1 where the movable blade head 8 is provided. The sliding flange 532 is slidably matched with the slide groove 12, so that the fixed blade holder 53 can achieve the purpose of reciprocating linear motion on the fuselage 1.

[0057] Based on the above embodiment, the sliding mechanism can also be other structures, such as setting a retractable telescopic rod between the fixed knife holder 53 and the fuselage 1, and the above effect can also be achieved by retracting the telescopic rod. Of course, it can also be other structures, which will not be elaborated here.

[0058] Based on the above embodiment, as a method in which the operating member can drive the fixed blade head 5 to move linearly when rotating, it can adopt an existing rocker mechanism, a crank connecting rod mechanism and the like. In this embodiment, referring to Figure 3 and 5 A dial head 6 can be provided on one end surface of the rotating head 31 away from the position where the screw penetrates, and a corresponding slot 531 is provided on the fixed knife holder 53. When the rotating head 31 rotates, its dial head 6 rotates around the screw as the rotation center, thereby driving the fixed knife holder 53 to slide along the slide groove. At this point, the rotating movement of the rotating head 31 can drive the fixed knife head 5 as a whole to reciprocate on the fuselage 1.

[0059] Although the preferred embodiments of the present invention are described in detail above, it should be clearly understood that the present invention may be modified and varied by those skilled in the art. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
