Description

Technical Field

[0001] This utility model relates to the field of electric clipper technology, specifically to a quick-release blade structure for an electric clipper. Background Technology

[0002] Electric hair clippers are commonly used tools in hairdressing, styling, and home personal care. Their blades, as the core component that directly contacts hair and performs the cutting action, require regular disassembly for cleaning, maintenance, or replacement to ensure cutting efficiency and hygiene. However, the connection structure between the blades and the main unit in existing electric hair clippers generally suffers from inconvenient disassembly and cumbersome operation, failing to meet users' needs for quick maintenance. Currently, most mainstream electric clipper heads on the market use screw fixing, clamp-on interference fit, or complex locking mechanisms for connection. While screw fixing provides a stable connection, disassembly requires specialized tools such as screwdrivers, making the process cumbersome. Frequent disassembly and assembly can also lead to stripped screws and worn threads, affecting connection reliability. Clamp-on interference fit structures, while tool-free, often feature rigid clamping designs that require significant external force for disassembly and assembly. This not only makes operation laborious but also increases the risk of damage to the clipper head or main unit connection due to improper force application. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-release structure for the blade of an electric clipper. By first removing the housing from the electric clipper body, and then using the quick-release component to disengage the blade assembly from the electric clipper connection, the blade assembly can be quickly detached.

[0004] To address the problems of existing technologies, this utility model provides a quick-release structure for the blade of an electric hair clipper, comprising: an electric hair clipper body, one end of which is provided with an electric hair clipper connecting part; a housing, detachably mounted on the electric hair clipper connecting part; a blade assembly, detachably mounted in the electric hair clipper connecting part; a quick-release assembly, disposed inside the electric hair clipper connecting part and used to detach the blade assembly; and a retaining plate having two sides disposed on the front and rear sides of the electric hair clipper connecting part for connecting the electric hair clipper connecting part and the housing. The blade assembly includes a sliding plate slidably disposed inside the electric hair clipper connecting part, with sliding parts at both ends of the sliding plate. The bottom sides of the electric hair clipper connecting part are also provided with sliding grooves that cooperate with the sliding parts. Support blocks are vertically disposed on both sides of the top of the sliding plate, and the support blocks have through holes. The electric hair clipper connecting part also has blind holes that coincide with the through holes on the support blocks. The quick-release assembly includes a plug that can be inserted into the through holes on the support blocks, one end of which is also inserted into the blind holes.

[0005] Preferably, the quick-release assembly further includes a guide block installed on the electric clipper connection portion, and the guide block slides in engagement with the insert block.

[0006] Preferably, the quick-release assembly further includes a guide rail fixed in the electric clipper connection part, and a slider is slidably disposed on the guide rail, and a transmission rod is rotatably connected to both ends of the slider, and the transmission rod is movably connected to the insert block.

[0007] Preferably, the quick-release assembly further includes a push rod connected to the slider, with one end of the push rod extending to the outside of the electric clipper connection and connected to a handle. A spring is also fitted on the push rod, with one end of the spring connected to the push rod and the other end of the spring connected to the outside of the electric clipper connection.

[0008] Preferably, the housing can cover the electric clipper connection part and contact the electric clipper body. The outer sides of the housing are also vertically provided with second limiting members, and the interior of the second limiting members is vertically provided with second limiting grooves. The two sides of the electric clipper connection part are also provided with first limiting members, and the first limiting members are vertically provided with first limiting grooves. The first limiting members and the second limiting members cooperate with each other.

[0009] Preferably, a retaining plate is slidably provided on the first and second limiting members, and a limiting rail that can cooperate with the first and second limiting grooves is also provided on the inner side of the retaining plate.

[0010] Preferably, the limiting rail forms a damping fit structure with the first limiting groove and the second limiting groove. When the limiting rail is displaced relative to the first limiting groove or the second limiting groove, the contact interface between the two can generate a damping force that hinders the relative movement, so as to realize the controllable sliding or positioning of the limiting rail in the first limiting groove and the second limiting groove.

[0011] Preferably, the cutter head assembly further includes a fixed blade disposed on the slide plate and a movable blade slidably disposed on top of the fixed blade.

[0012] The advantages of this utility model compared to the prior art are: This application applies an upward axial thrust to the clamping plate, causing it to displace along a preset trajectory. During this process, the damping engagement structure between the limiting rails on the clamping plate and the first and second limiting grooves gradually releases its locking state. The limiting rails completely disengage from the first and second limiting grooves along the groove axis, at which point the limiting constraints between the housing and the electric clipper body are released. Next, a horizontal pulling force is applied to the housing, causing it to move along a trajectory parallel to the end face of the electric clipper connection until the housing is completely separated from the electric clipper body. Subsequently, an axial pressing force is applied to the push rod, which transmits the external force to the slider, driving the slider to produce linear displacement along the guide mechanism. Under the linkage of the slider, the insert block moves synchronously with the slider, releasing the insertion engagement between the insert block and the support block. The insert block completely disengages from the support block, at which point the rigid connection between the cutter head assembly and the electric clipper connection is released. Finally, a pulling force is applied to the cutter head assembly away from the electric clipper's connecting part, causing the cutter head assembly to move along the guide structure of the electric clipper's connecting part until the cutter head assembly is completely freed from the constraint range of the electric clipper's connecting part, thereby achieving the overall disassembly of the cutter head assembly. This disassembly process, through a step-by-step linkage design of the mechanical structure, allows for rapid separation of the cutter head assembly without the need for any external tools, solely through manual operation. This effectively improves disassembly and assembly efficiency while avoiding component damage caused by excessive force in traditional structures. Attached Figure Description

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1-8As shown, this utility model provides a quick-release structure for the blade of an electric hair clipper, comprising: an electric hair clipper body 1, one end of which is provided with an electric hair clipper connecting part 11; a housing 2, detachably mounted on the electric hair clipper connecting part 11; a blade assembly 3, detachably mounted in the electric hair clipper connecting part 11; a quick-release assembly 4, disposed inside the electric hair clipper connecting part 11 and used to remove the blade assembly 3; and a retaining plate 5, having two plates disposed on the front and rear sides of the electric hair clipper connecting part 11, used to connect the electric hair clipper connecting part 11 and the housing 2; as a protective component, it can cover the electric hair clipper connecting part 11 and contact the electric hair clipper body 1, providing dustproof and collision-proof protection for the internal blade assembly 3 and quick-release assembly 4, while maintaining the integrity of the overall appearance of the electric hair clipper. The cutter head assembly 3 includes a slide plate 31 slidably disposed inside the electric clipper connecting part 11. Slide members 312 are provided at both ends of the slide plate 31. Slide grooves 13 that mate with the slide members 312 are also provided on both sides of the bottom of the electric clipper connecting part 11. Support blocks 311 are vertically disposed on both sides of the top of the slide plate 31, and each support block 311 has a through hole. The electric clipper connecting part 11 also has blind holes that coincide with the through holes on the support blocks 311. The quick-release assembly 4 includes a plug 41 that can be inserted into the through holes on the support blocks 311, with one end of the plug 41 also inserted into the blind hole. As the basic load-bearing structure of the entire device, it provides an installation reference and support for other components. The electric clipper connecting part 11 at one end is the core connecting area, used to assemble the housing 2, the blade assembly 3, and the main body. The sliding grooves 13 on both sides of the bottom of the electric clipper connecting part 11 cooperate with the sliding parts 312 of the blade assembly 3 to ensure the precise movement direction of the blade assembly 3. The blind holes on the connecting part correspond to the through holes of the support block 311, and the blade assembly 3 is fixed by inserting the insert block 41. The electric clipper connecting part 11 is provided with first limiting members 12 on both sides. The first limiting members 12 have a first limiting groove 121 vertically arranged in the first limiting member 12, which cooperates with the second limiting member 21 on the housing 2 to provide a positioning and connection basis for the installation of the housing 2. The quick-release assembly 4 also includes a guide block 42 installed on the electric clipper connecting part 11, and the guide block 42 slides with the insert block 41. The quick-release assembly 4 also includes a guide rail 45 fixed in the electric clipper connecting part 11, and a slider 412 is slidably disposed on the guide rail 45. A transmission rod 411 is rotatably connected to both ends of the slider 412, and the transmission rod 411 is movably connected to the insert block 41. The quick-release assembly 4 also includes a push rod 43 connected to the slider 412, with one end of the push rod 43 extending to the outside of the electric clipper connecting part 11 and connected to a handle. A spring 44 is also sleeved on the push rod 43, with one end of the spring 44 connected to the push rod 43 and the other end connected to the outside of the electric clipper connecting part 11.

[0024] Pressing the handle of push rod 43 compresses spring 44, causing push rod 43 to move slider 412 along guide rail 45. Slider 412 pulls insert block 41 along guide block 42 via transmission rod 411, causing insert block 41 to disengage from through hole and blind hole of support block 311, releasing the lock of cutter head assembly 3. Finally, pull fixed blade 32 along slide groove 13, causing slide 312 of slide plate 31 to move along slide groove 13, allowing cutter head assembly 3 to be removed as a whole. The installation process is the reverse of the disassembly process. Under the reset action of spring 44, insert block 41 automatically inserts into through hole and blind hole to fix cutter head assembly 3. The damping of clamping plate 5 enables quick installation of housing 2. The entire process can be completed manually without tools, significantly improving the efficiency and convenience of disassembly and assembly of cutter head assembly 3.

[0025] The housing 2 can cover the electric clipper connecting part 11 and contact the electric clipper body 1. Second limiting members 21 are vertically arranged on both sides of the outer surface of the housing 2. A second limiting groove 211 is vertically arranged inside the second limiting member 21. First limiting members 12 are also arranged on both sides of the electric clipper connecting part 11. A first limiting groove 121 is vertically arranged in the first limiting member 12. The first limiting member 12 and the second limiting member 21 cooperate with each other. A locking plate 5 is slidably arranged on the first limiting member 12 and the second limiting member 21. A limiting rail 51 that cooperates with the first limiting groove 121 and the second limiting groove 211 is also provided inside the locking plate 5. The limiting rail 51 forms a damping fit structure with the first limiting groove 121 and the second limiting groove 211. When the limiting rail 51 is displaced relative to the first limiting groove 121 or the second limiting groove 211, the contact interface between the two can generate a damping force that hinders the relative movement, so as to realize the controllable sliding or positioning of the limiting rail 51 in the first limiting groove 121 and the second limiting groove 211.

[0026] In the assembled state, the housing 2 covers the electric clipper connecting part 11 and contacts the electric clipper body 1. The first limiting member 12 and the second limiting member 21 cooperate with each other. The limiting rail 51 of the clamping plate 5 forms a damping cooperation with the first limiting groove 121 and the second limiting groove 211, fixing the housing 2 on the electric clipper connecting part 11. When it is necessary to disassemble the cutter head assembly 3, first push the clamping plate 5 upward, so that the limiting rail 51 overcomes the damping force and slides in the first limiting groove 121 and the second limiting groove 211 and disengages from them, releasing the constraint of the housing 2, and removing the housing 2 in the horizontal direction; this facilitates subsequent disassembly.

[0027] The blade assembly 3 also includes a fixed blade 32 mounted on a slide plate 31 and a movable blade 33 slidably mounted on top of the fixed blade 32. The fixed blade 32 is fixedly mounted on the slide plate 31, serving as a reference component for the cutting action and providing support and a base for the movable blade 33; the movable blade 33 is slidably mounted on top of the fixed blade 32, and through relative sliding with the fixed blade 32, they work together to cut the hair.

[0028] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
