Description

Technical Field

[0001] This utility model relates to the field of hair clipper technology, specifically a connection structure for a hair clipper blade. Background Technology

[0002] The clipper blade is snapped onto the handle. To ensure safety and prevent the blade from coming loose from the handle during use, the blade is tightly secured to the handle. After a haircut, the blade often needs to be disassembled to clean out any loose hair inside.

[0003] Traditional hair clippers have blades that are fixed to the handle. When disassembling them, external force must be used to pry the blades off the handle. The disassembly process is very laborious and can easily damage the blades. Moreover, after repeated disassembly and reassembly, wear will occur between the blades and the clipper handle. This may lead to a decrease in the stability of the hair clipper, thereby reducing its lifespan. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a connection structure for the hair clipper blade, thereby solving the problem mentioned in the background art that traditional hair clippers require external force to pry the blade off the handle during disassembly, as the blade is clamped to the handle. This disassembly process is laborious and easily damages the blade. Furthermore, after repeated disassembly of the blade, wear will occur between the blade and the hair clipper handle, which may lead to a decrease in the stability of the hair clipper and a reduction in its service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connecting structure for a hair clipper head, including a hair clipper handle, a connecting block fixedly installed at the top of the hair clipper handle, a connecting groove formed in the connecting block, a mating block disposed in the connecting groove, a protrusion fixedly installed at the bottom of the mating block, four positioning grooves formed on the outer surface of the protrusion, the four positioning grooves being arranged in a circular array on the outer surface of the protrusion, elastic sheets fixedly installed at both the front and rear ends of the protrusion, and a locking block fixedly installed at the bottom position of the outer surface of the elastic sheet, the locking block installed on the outer surface of the elastic sheet being inverted triangular in shape.

[0006] By adopting the above technical solution, the protrusion at the bottom of the mating block is aligned with the connecting groove. After the protrusion is inserted into the connecting groove, the positioning post installed in the connecting groove will engage with the positioning groove in the protrusion, thereby preventing the mating block from rotating. After the mating block is inserted into the connecting groove, the elastic plates installed at the front and rear ends of the protrusion will tilt under the action of the locking block, thereby preventing the locking block from affecting the installation of the mating block. Afterwards, when the locking block moves into the slot, the elastic plates will reset, thereby locking the locking block into the slot, thus ensuring that the mating block is stably installed.

[0007] Preferably, the connecting block has slots at both the front and rear ends, a limit block is fixedly installed on the outer surface of the slot, a spring is fixedly installed in each slot, a button is fixedly installed on the outer end of the spring, and a push block is fixedly installed on the inner surface of the button.

[0008] Using the above technical solution, pressing the button inward causes the button to retract, which in turn causes the push block inside the button to push out the locking block, allowing the operator to disassemble the docking block. Therefore, the connection point of this connection structure will not wear after multiple disassemblies and installations, and the installation and disassembly are also relatively simple.

[0009] Preferably, four positioning posts are fixedly installed in the connecting groove opened in the connecting block, and the four positioning posts are arranged in a circumferential array in the connecting groove. An annular groove is opened at the top of the connecting block.

[0010] Using the above technical solution, after the protrusion is inserted into the connecting groove, the positioning post installed in the connecting groove will engage with the positioning groove in the protrusion, thereby preventing the mating block from rotating. The annular plate is inserted into the annular groove on the connecting block, so the connection between the connecting block and the mating block can be kept sealed, thus effectively preventing hair fragments from entering the connecting groove and affecting the installation and disassembly of the connection structure.

[0011] Preferably, an annular plate is fixedly installed at the bottom of the docking block, and a connecting component for connecting with the blade is provided at the top of the docking block.

[0012] Using the above technical solution, after the mating block is installed, the annular plate at the bottom of the mating block is inserted into the annular groove on the connecting block. Therefore, the connection between the connecting block and the mating block can be kept sealed, which can effectively prevent fine hairs from entering the connecting groove and affecting the installation and disassembly of the connection structure.

[0013] Preferably, the locking block located at the bottom of the outer surface of the elastic sheet is movably engaged in the slot opened in the connecting block, and the locking block is located directly in front of the pushing block.

[0014] By adopting the above technical solution, the limiting block in the slot can effectively restrict the button, thereby preventing the outer end of the button from extending out of the slot. Therefore, this can effectively prevent the button from being accidentally pressed by the operator, causing the push block to push the slot block out of the slot and resulting in the docking block becoming loose.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The connecting structure of this hair clipper head involves aligning the protrusion at the bottom of the docking block with the connecting groove. After the docking block is inserted into the connecting groove, the elastic plates installed at both ends of the protrusion will tilt under the action of the locking block. Then, when the locking block moves into the slot, the elastic plates will reset, thus locking the locking block into the slot, thereby ensuring the docking block is stably installed. When the docking block needs to be disassembled, pressing the button inward will cause the button to drive the spring to contract, which in turn pushes the locking block out of the inner end of the button, allowing the operator to remove the docking block. Therefore, the connection point will not wear after multiple disassemblies and installations, and the installation and disassembly are relatively simple.

[0016] 2. The connection structure of the hair clipper head, through the limiting block in the slot, can effectively restrict the button, thereby preventing the outer end of the button from extending out of the slot. Therefore, it can effectively prevent the operator from accidentally pressing the button and pushing the block out of the slot, which would cause the connecting block to become loose. Furthermore, the shape of the block is an inverted triangle, which can effectively ensure that the block is firmly locked into the slot. When it is necessary to disassemble the connecting block, the operator must press it simultaneously to push the block out of the slot. Therefore, it can effectively prevent the operator from accidentally pressing it during use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Referring to Figures 1-4, a connecting structure for a hair clipper head is described. A connecting block 2 is fixedly installed at the top of the hair clipper handle 1. A connecting groove 3 is formed within the connecting block 2, and a mating block 4 is disposed within the connecting groove 3. A protrusion 5 is fixedly installed at the bottom of the mating block 4. Four positioning grooves 6 are formed on the outer surface of the protrusion 5, arranged in a circular array. Elastic sheets 7 are fixedly installed at both the front and rear ends of the protrusion 5. A locking block 8 is fixedly installed at the bottom of the outer surface of the elastic sheet 7. The locking block 8 on the outer surface of the elastic sheet 7 is inverted triangular in shape. A locking groove 9 is formed at both the front and rear ends of the connecting block 2, and the outer surface of the locking groove 9 is fixed... A limiting block 10 is fixedly installed. A spring 11 is fixedly installed in the slot 9. A button 12 is fixedly installed at the outer end of the spring 11. A push block 13 is fixedly installed on the inner surface of the button 12. Four positioning posts 14 are fixedly installed in the connecting groove 3 opened in the connecting block 2. The four positioning posts 14 are arranged in a circumferential array in the connecting groove 3. An annular groove 15 is opened at the top of the connecting block 2. An annular plate 16 is fixedly installed at the bottom of the docking block 4. A connecting component 17 for connecting with the blade is provided at the top of the docking block 4. A locking block 8 provided at the bottom of the outer surface of the elastic sheet 7 is movably engaged in the slot 9 opened in the connecting block 2. The locking block 8 is located directly in front of the push block 13.

[0021] Working principle: When installing the clipper head, the operator aligns the protrusion 5 at the bottom of the connecting block 4 with the connecting groove 3. After the protrusion 5 is inserted into the connecting groove 3, the positioning post 14 installed in the connecting groove 3 will engage with the positioning groove 6 in the protrusion 5, thus preventing the connecting block 4 from rotating. After the connecting block 4 is inserted into the connecting groove 3, the elastic plates 7 installed at both ends of the protrusion 5 will tilt under the action of the locking block 8, thus preventing the locking block 8 from affecting the installation of the connecting block 4. After the locking block 8 moves into the slot 9, the elastic plate 7 will reset, thus locking the locking block 8 into the slot 9, thereby ensuring the stable installation of the connecting block 4. After the connecting block 4 is installed, the annular plate 16 at the bottom of the connecting block 4 is inserted into the annular groove 1 on the connecting block 2. Within 5, this ensures that the connection between connecting block 2 and mating block 4 remains sealed, effectively preventing fine hair from entering the connecting groove 3 and affecting the installation and disassembly of the connection structure. After the mating block 4 is installed, the operator can install the blade with the connecting component 17. When the mating block 4 needs to be disassembled, the operator presses the button 12 inward, causing the button 12 to drive the spring 11 to retract, thereby causing the push block 13 at the inner end of the button 12 to push out the locking block 8. Then, the operator can pull the mating block 4 upward to disassemble it. Therefore, the connection point of this connection structure will not wear after multiple disassemblies and installations, and the installation and disassembly are relatively simple, allowing the operator to quickly install and disassemble.

[0022] Example 2: Referring to Figures 1-4, a connection structure for a hair clipper head is described. The connecting block 2 has slots 9 at both its front and rear ends. Limiting blocks 10 are fixedly installed on the outer surface of each slot 9. Springs 11 are fixedly installed within each slot 9. A button 12 is fixedly installed on the outer end of each spring 11. A pushing block 13 is fixedly installed on the inner surface of each button 12. A locking block 8, located at the bottom of the outer surface of the elastic sheet 7, is movably engaged within the slots 9 in the connecting block 2. The locking block 8 is positioned directly in front of the pushing block 13. The locking block 8 on the outer surface of the elastic sheet 7 is shaped like an inverted triangle.

[0023] Working principle: Due to the limiting block 10 set in the slot 9, the limiting block 10 can effectively restrict the button 12, thereby preventing the outer end of the button 12 from extending out of the slot 9. Therefore, it can effectively prevent the button 12 from pushing the pushing block 13 and pushing the locking block 8 out of the slot 9 due to accidental touch by the operator, which would cause the docking block 4 to become loose. Furthermore, the locking block 8 is shaped like an inverted triangle, which can effectively ensure that the locking block 8 is firmly locked into the slot 9. When it is necessary to disassemble the docking block 4, the operator needs to press it simultaneously to push the locking block 8 out of the slot 9. Therefore, it can effectively prevent accidental touch by the operator during use.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
