Abstract
Description
Technical Field
[0001] This utility model relates to the field of razor technology, and in particular to a razor connection structure. Background Technology
[0002] Manual cassette shavers typically consist of a shaver head assembly and a handle. The shaver head assembly is detachably connected to the handle via a connecting structure. To facilitate shaver head replacement, a spring and ejection mechanism are usually incorporated into the connecting structure. When the shaver head release button is pressed, the spring pushes the ejection mechanism to pop the shaver head assembly off the handle, allowing the user to detach the shaver head assembly without applying additional force, improving ease of operation and safety. However, this design results in a more complex connecting structure with more parts, increasing production costs and assembly difficulty, while also increasing the overall weight and size of the shaver, affecting portability. Utility Model Content
[0003] This utility model provides a razor connection structure that can improve the ease of use of razors.
[0004] To solve the above-mentioned technical problems, this utility model provides a razor connection structure, characterized in that it includes:
[0005] A knife handle, wherein a slot is provided on the knife handle, a latch is provided on the inner wall of the slot, and a spring button is provided at the latch;
[0006] The cutter head connector has a plug-in portion that mates with the slot. The plug-in portion has an elastic buckle with a first guide slope. When the plug-in portion is inserted into the slot, the elastic buckle engages with the slot, and the elastic button abuts against the first guide slope.
[0007] As a preferred embodiment of the above technical solution, the elastic buckle includes a connecting plate, one end of which is connected to the blade connector, and the other end of which protrudes to one side to form a buckle portion. A reinforcing rib is provided between the buckle portion and the connecting plate, and the first guide slope is provided on the reinforcing rib.
[0008] As a preferred embodiment of the above technical solution, the number of reinforcing ribs is two, and the two reinforcing ribs are symmetrically distributed at both ends of the buckle portion.
[0009] As a preferred embodiment of the above technical solution, the elastic button is provided with a pressing part and a connecting part, the pressing part is located at the bayonet, and the pressing part is connected to the inner sidewall of the bayonet through the connecting part.
[0010] As a preferred embodiment of the above technical solution, the pressing part protrudes upward to form a pressing protrusion, and the pressing protrusion is exposed on the upper part of the bayonet.
[0011] As a preferred embodiment of the above technical solution, the plug-in portion is provided with a support plate, and the support plate is provided with a guide portion.
[0012] As a preferred embodiment of the above technical solution, the buckle portion is provided with a second guide slope, and the opening of the slot is provided with a guide groove, wherein the second guide slope cooperates with the guide groove.
[0013] As a preferred embodiment of the above technical solution, a guide limiting plate is provided in the slot, and a guide limiting groove is provided on the insertion part, wherein the guide limiting plate and the guide limiting groove cooperate with each other.
[0014] As a preferred embodiment of the above technical solution, the slot is provided with a plurality of circumferential limiting grooves, and the insertion part is provided with a plurality of circumferential limiting protrusions, wherein the circumferential limiting grooves cooperate with the circumferential limiting protrusions.
[0015] This utility model provides a shaver connection structure, including: a handle and a shaver head connector. The shaver head connector is used to fix the shaver head. In use, the insertion part of the shaver head connector is aligned with the slot on the handle and pushed in axially. During insertion, the first guide slope of the elastic buckle contacts the inner wall of the slot and generates elastic deformation. When inserted into place, the elastic buckle snaps into the slot, and at the same time, the elastic button abuts against the first guide slope to achieve quick locking and ensure a stable connection. In disassembly, the elastic button is pressed to push the first guide slope, forcing the elastic buckle to disengage from the slot. Pressing the elastic button further causes the elastic buckle to undergo elastic deformation. Under the combined action of the elastic buckle's own elasticity, the first guide slope, and the elastic button, the shaver head connector will automatically pop out from the handle, facilitating the disassembly and replacement of the shaver head. This allows the user to complete the separation action without additional force when disassembling the shaver head assembly, improving operational convenience and safety. At the same time, the absence of a practical spring and ejection mechanism effectively reduces the complexity of the product structure, the number of parts and assembly difficulty, improves overall reliability, and also reduces the overall weight and size of the shaver, increasing the product's lightweight and compactness, making it easier to carry and use.
[0016] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, specific embodiments of this utility model are given below.

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] See Figures 1 to 5 This utility model provides a razor connection structure, characterized in that it includes:
[0025] A knife handle 1, wherein a slot 101 is provided on the knife handle 1, and a latch 102 is provided on the inner wall of the slot 101, and a spring button 2 is provided at the latch 102;
[0026] The cutter head connector 3 has a plug-in portion 301 that mates with the slot 101. The plug-in portion 301 has an elastic buckle 4 and a first guide slope 401. When the plug-in portion 301 is inserted into the slot 101, the elastic buckle 4 engages with the bayonet 102, and the elastic button 2 abuts against the first guide slope 401.
[0027] This utility model provides a shaver connection structure, including: a handle 1 and a blade head connector 3. The blade head connector 3 is used to fix the blade head. In use, the insertion part 301 of the blade head connector 3 is aligned with the slot 101 on the handle 1 and pushed in axially. During the insertion process, the first guide slope 401 of the elastic buckle 4 contacts the inner wall of the slot 102 and generates elastic deformation. When inserted into place, the elastic buckle 4 engages with the slot 102, and at the same time, the elastic button 2 abuts against the first guide slope 401 to achieve quick locking and ensure connection. For secure disassembly, press the elastic button 2 to push the first guide slope 401, forcing the elastic buckle 4 to disengage from the latch 102. Continue pressing the elastic button 2 to cause the elastic buckle 4 to elastically deform. Under the combined action of the elastic buckle 4's own elasticity, the first guide slope 401, and the elastic button 2, the blade head connector 3 will automatically pop out from the handle 1, facilitating the disassembly and replacement of the blade head. This allows users to complete the separation action without applying additional force when disassembling the blade head assembly, improving operational convenience and safety. Simultaneously, the absence of a spring and ejection mechanism effectively reduces the complexity of the product structure, decreases the number of parts and assembly difficulty, improves overall reliability, and reduces the overall weight and size of the shaver, enhancing its lightweight and compact design, making it easy to carry and use.
[0028] In a further embodiment of this invention, the elastic buckle 4 includes a connecting plate 402. One end of the connecting plate 402 is connected to the blade connector 3, and the other end of the connecting plate 402 protrudes to one side to form a buckle portion 403. A reinforcing rib 404 is provided between the buckle portion 403 and the connecting plate 402, and the first guide slope 401 is provided on the reinforcing rib 404.
[0029] In this embodiment, the elastic buckle 4 includes a connecting plate 402, which is made of an elastic material. One end of the connecting plate 402 protrudes to one side to form a buckle portion 403. A reinforcing rib 404 is provided between the buckle portion 403 and the connecting plate 402. The first guide slope 401 is disposed on the reinforcing rib 404. When the insertion portion 301 is inserted into the slot 101, the buckle portion 403 is squeezed by the inner wall of the slot 101, causing the connecting plate 402 to undergo elastic deformation. The first guide slope 401 on the reinforcing rib 404... The inclined surface 401 slides and compresses accordingly. When the latching part 403 passes the bayonet 102, the connecting plate 402 returns to its original shape, and the latching part 403 quickly embeds into the bayonet 102 to achieve locking. During disassembly, pressing the elastic button 2 pushes the first guide inclined surface 401, causing the latching part 403 to be deflected towards the connecting plate 402 and disengage from the bayonet 102. Under the combined action of the elastic force of the connecting plate 402 itself, the first guide inclined surface 401, and the elastic button 2, the insertion part 301 is gradually pushed out, completing the automatic ejection separation. The reinforcing rib 404 and the first guide inclined surface 401 are integrated into a single design, enhancing the structural strength and response sensitivity of the elastic latch 4 and ensuring stable performance after multiple insertions and removals. The entire connection structure is compact and reliable, taking into account both lightweight and high reliability requirements.
[0030] In a further embodiment of this invention, there are two reinforcing ribs 404, which are symmetrically distributed at both ends of the snap-fit portion 403.
[0031] In this embodiment, the two reinforcing ribs 404 are symmetrically distributed at both ends of the latching part 403, which makes the force more balanced and effectively prevents the latching part 403 from tilting or getting stuck on one side during insertion and removal, thus improving the smoothness of connection and separation.
[0032] In a further embodiment of this invention, the elastic button 2 is provided with a pressing part 201 and a connecting part 202. The pressing part 201 is located at the bayonet 102, and the pressing part 201 is connected to the inner sidewall of the bayonet 102 through the connecting part 202.
[0033] In this embodiment, the elastic button 2 is provided with a pressing part 201 and a connecting part 202. The connecting part 202 is an elastic connecting part 202. The pressing part 201 is connected to the inner side of the bayonet 102 through the elastic connecting part 202. When pressed, the connecting part 202 undergoes elastic deformation, transmitting a pushing force to the first guide slope 401, causing the latching part 403 to deflect and disengage from the bayonet 102. After releasing the pressure, the elastic connecting part 202 automatically resets, ensuring that the button rebounds to its original position and maintaining structural stability. This design simplifies the operation and improves the user experience.
[0034] In a further embodiment of this invention, the pressing part 201 protrudes upward to form a pressing protrusion 203, and the pressing protrusion 203 is exposed on the upper part of the bayonet 102.
[0035] In this embodiment, the pressing protrusion 203 is exposed outside the bayonet 102, which facilitates finger touch operation and thus improves the convenience of operation.
[0036] In a further embodiment of this invention, a support plate 302 is provided on the plug-in portion 301, and a guide portion 303 is provided on the support plate 302.
[0037] In this embodiment, a support plate 302 is provided on the insertion part 301. When the insertion part 301 is inserted into the slot 101, the support plate 302 fits against the inner wall of the slot 101, providing support and preventing the cutter head connector 3 from shaking or loosening during use, thus improving connection stability. Simultaneously, using the support plate 302 as a support structure effectively reduces the contact area between the insertion part 301 and the slot 101, making the insertion process smoother, reducing frictional resistance, and minimizing wear. The support plate 302 extends along the insertion direction, and a guide part 303 is provided at its end. The guide part 303 has an inclined structure, which guides the support plate 302 smoothly into the slot 101 during insertion, preventing insertion obstruction due to misalignment, thereby improving ease of use.
[0038] In a further embodiment of this invention, the latching part 403 is provided with a second guide slope 405, and the opening of the slot 101 is provided with a guide groove 105, wherein the second guide slope 405 cooperates with the guide groove 105.
[0039] In this embodiment, the latching part 403 is provided with a second guide slope 405, and the opening of the slot 101 is provided with a guide groove 105. During the insertion process, the second guide slope 405 and the guide groove 105 cooperate with each other to guide the latching part 403 to slide smoothly into the slot 101, avoiding collision or jamming caused by angle deviation, thereby further improving the ease of use.
[0040] In a further embodiment of this invention, a guide limiting plate 103 is provided in the slot 101, and a guide limiting groove 304 is provided on the insertion part 301, wherein the guide limiting plate 103 and the guide limiting groove 304 cooperate.
[0041] In this embodiment, a guide limiting plate 103 is provided in the slot 101, and a guide limiting groove 304 is provided on the plug-in part 301. During the plug-in process, the guide limiting plate 103 is embedded in the guide limiting groove 304, and the two slide together to effectively limit the lateral displacement of the plug-in part 301, ensure stable alignment during the connection process, improve the accuracy and reliability of the connection, and prevent shaking during use.
[0042] In a further embodiment of this invention, the slot 101 is provided with a plurality of circumferential limiting grooves 104, and the insertion part 301 is provided with a plurality of circumferential limiting protrusions 305, wherein the circumferential limiting grooves 104 cooperate with the circumferential limiting protrusions 305.
[0043] In this embodiment, a plurality of circumferential limiting grooves 104 are provided on the side wall of the slot 101, and a plurality of circumferential limiting protrusions 305 are provided on the insertion part 301. During the insertion process, the circumferential limiting protrusions 305 are embedded in the corresponding circumferential limiting grooves 104 to achieve circumferential limiting, thereby preventing relative rotation between the blade head connector 3 and the handle 1 during use, ensuring that the blade head assembly remains stable during shaving, avoiding slippage, and thus effectively improving the safety and user experience of shaving.
