Description

Technical Field

[0001] This utility model relates to the field of hair clipper technology, and in particular to a hook structure and a hair clipper using the structure. Background Technology

[0002] Hair clippers, also known as electric clippers, are a common hair-cutting tool. In daily use, hair clippers are usually placed directly on a carrier, such as a table or charging base. Existing technologies include products with hanging holes or hooks on the hair clippers for suspension. However, hanging holes or protruding hooks obviously take up a lot of space, affecting the aesthetics and practicality of the hair clippers. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a hook that solves the problem that the existing hook structure is relatively poor in terms of aesthetics and practicality when installed on a hair clipper.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a hook structure, including a hook hinged to a corresponding carrier, an elastic locking part provided on the carrier, and a mating part provided on the hook. The elastic locking part has a locked state that cooperates with the mating part to lock the hook and the carrier relative to each other, and an unlocked state that allows the two to rotate relative to each other. When the hook rotates, it abuts against the elastic locking part and enters the unlocked state. After the hook stops rotating relative to the carrier, the elastic locking part resets to cooperate with the mating part to enter the locked state.

[0005] Furthermore, the hook is equipped with a pivot, and the hook is hinged to the carrier through the pivot. The mating part includes several positioning holes arranged around the pivot, and the elastic locking part is inserted into the positioning holes to restrict the rotation of the hook.

[0006] By adopting the above technical solution and setting multiple positioning holes around the carrier, the advantage is that when the hook rotates around the carrier to any angle, it can be inserted into the corresponding positioning hole through the elastic locking part, thereby positioning the hook at any angle with the carrier. This allows the hook to be set at a right angle or an acute angle with the carrier according to the actual product hanging needs, thus enriching the usage scenarios of the hook and the practicality of the product.

[0007] Furthermore, the elastic locking part includes a locking element and an elastic element. The locking element is elastically connected to the carrier through the elastic element, and the locking element and the positioning hole form a plug-in fit.

[0008] By adopting the above technical solution, the locking component is movably connected to the carrier through the elastic component, which facilitates the separation of the locking component from the positioning hole after the elastic component is compressed when the insertion rod is squeezed by the hook. At the same time, when the locking component and the corresponding positioning hole are matched and aligned again, the locking component and the positioning hole can be locked again under the elastic reset action of the elastic component.

[0009] Furthermore, the locking element includes a ball bearing, and the positioning hole is an arc-shaped concave surface located on the rotating shaft.

[0010] By adopting the above technical solution, the ball bearing and the arc-shaped concave surface design make it easy for the hook to rotate around the pivot axis. The arc-shaped concave surface can squeeze the ball bearing, thereby causing the ball bearing to be displaced after compressing the elastic element, so as to allow the ball bearing to separate from the positioning hole.

[0011] Furthermore, the locking lever includes a plug rod that forms a plug-in fit with the positioning hole.

[0012] By adopting the above technical solution, the insertion method of the plug rod and the positioning hole makes disassembly and separation convenient.

[0013] Furthermore, at least one of the contact end shapes of the insertion rod and the positioning hole, and the shape of the positioning hole, is an arc-shaped structure.

[0014] Through the above technical solution, by setting the arc structure, the relative displacement of the insertion rod relative to the elastic element can be achieved by squeezing the arc structure when the shaft rotates, thereby releasing the insertion locking effect between the insertion rod and the positioning hole.

[0015] Furthermore, a blind hole is provided on the carrier, and the locking element is elastically movable in the blind hole through an elastic element.

[0016] By adopting the above technical solution, the blind hole design facilitates the concealment of the entire elastic locking part, thereby improving product precision and optimizing product size.

[0017] Furthermore, both the hook and the carrier are equipped with magnetic components. When the hook is flipped and brought together on the carrier, the hook magnetically attracts the carrier through the magnetic components.

[0018] By adopting the above technical solution, the magnetic component can improve the stability of the connection between the hook and the carrier after the hook is folded and closed.

[0019] Furthermore, the rotating shaft includes a column at the end of the hook and an elastic telescopic rod at the end of the column. The carrier is provided with a shaft groove, and the column is rotatably connected to the shaft groove through the elastic telescopic rod.

[0020] By adopting the above technical solution, the setting of the shaft groove facilitates the storage of the shaft column, optimizes the product structure, and avoids the shaft being exposed, which affects the aesthetics. The setting of the elastic telescopic rod allows for convenient disassembly or assembly of the hook and the carrier by utilizing its contraction.

[0021] A hair clipper includes a housing with a hook structure as described above.

[0022] Compared with the prior art, the advantages of this utility model are:

[0023] 1. This utility model relates to a hook that is hinged to a corresponding carrier, allowing the hook to be folded or unfolded relative to the carrier. When unfolded, the carrier can be hung on a wall or other surface using the hook. When folded, the hook avoids taking up space on the carrier, effectively improving the product's aesthetics and the hook's practicality. Furthermore, by providing an elastic locking part on the carrier and a mating part on the hook, the hook and carrier can be locked together, maintaining the unfolded angle between them. When the hook is subjected to external force and rotates, it can disengage from the positioning hole by abutting the elastic locking part, allowing the hook to rotate relative to the carrier. Thus, in actual use, the hook can be positioned at any unfolded angle on the carrier as needed, adapting to different hook angle requirements and effectively increasing the versatility and convenience of the hook's use.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] Reference Figure 1 , 2 3 and 4, the hook structure includes a hook 300 hinged to a corresponding carrier, the carrier is provided with an elastic locking part 220, the hook 300 is provided with a mating part, the elastic locking part 220 has a locked state that cooperates with the mating part to lock the hook 300 and the carrier relative to each other, and an unlocked state that allows the two to rotate relative to each other. When the hook 300 rotates, it abuts against the elastic locking part 220 to enter the unlocked state. After the hook 300 stops rotating relative to the carrier, the elastic locking part 220 resets to cooperate with the mating part to enter the locked state.

[0037] In this embodiment, the carrier can be a hair clipper, electric clipper, hair dryer, shaver, or other electrical or non-electrical appliance on which the hook 300 can be set, and is not limited to a specific product. In this embodiment, the carrier is a hair clipper as an example, and the specific structure of the hook 300 is described.

[0038] In this embodiment, refer to Figure 2 The hair clipper includes a housing 100, a hook 300 is hinged to the end of the housing 100 away from the blade, an end cap 200 is provided at the corresponding end of the housing 100, an elastic locking part 220 is provided on the end cap 200, the hook 300 includes a ring 310 and a rotating shaft 320 provided at the lower end of the ring 310, the ring 310 is hollow inside so that the hair clipper can be hung on the corresponding mounting surface through the hollow part, the end cap 200 is provided with a shaft groove 230 at the position corresponding to the rotating shaft 320, and the rotating shaft 320 is rotatably connected in the shaft groove 230 to realize the rotatable connection between the hook 300 and the end cap 200.

[0039] In this embodiment, refer to Figure 3 and 4The elastic locking part 220 includes a locking member and an elastic member 221. The locking member is elastically and movably disposed on the end cap 200 via the elastic member 221. The mating part includes a plurality of positioning holes 3211 arranged around the outer periphery of the rotating shaft 320. The elastic movement direction of the locking member is opposite to the position of the rotating shaft 320. The locking member can be inserted into the corresponding positioning hole 3211 on the rotating shaft 320 under the elastic force of the elastic member 221. In this way, by using the insertion and mating between the locking member and the positioning hole 3211, the hook 300 and the end cap 200 can be locked relative to each other to maintain the unfolding angle between the hook 300 and the end cap 200. When an external force is applied to the ring 310, causing it to rotate relative to the end cap 200 with the pivot 320 as the pivot point, the pivot 320 will press the locking member through the positioning hole 3211, thereby causing the locking member to compress the elastic member 221. After the elastic member 221 deforms, the ring 310 is allowed to rotate. When the ring 310 rotates relative to the end cap 200 to a predetermined angle, such as 90°, 45° or other angles between the ring 310 and the end cap 200, the locking member and the corresponding positioning hole 3211 on the pivot 320 are matched again. The elastic member 221 applies a force to the locking member toward the corresponding positioning hole 3211, thereby causing the locking member to be inserted and matched with the positioning hole 3211 corresponding to the ring 310 after rotation, thus restricting the rotation of the ring 310 again. Therefore, by using multiple positioning holes 3211 spaced around the outer periphery of the rotating shaft 320, the ring body 310 can be locked at any position on one side of the end cap 200 after the rotation of the ring body 310 stops, so that the hook 300 can adapt to the angle setting requirements of different installation scenarios.

[0040] In this embodiment, one or two positioning holes 3211 can be provided. When two positioning holes 3211 are provided, refer to... Figure 4 The lines connecting the two positioning holes 3211 and the axis of the rotating shaft 320 are set at right angles. This angle setting corresponds to the folded position of the hook 300 folded and closed onto the end cap 200 and the unfolded position when the hook 300 and the end cap 200 are at a 90-degree angle.

[0041] Furthermore, refer to Figure 2 In order to limit the elastic deformation direction of the elastic element 221 and avoid the elastic element 221 and the locking element being exposed, which would affect the product appearance and the assembly precision of the product structure, a blind hole 210 is provided in the shaft groove 230. The elastic element 221 and the locking element are respectively provided in the blind hole 210. One end of the elastic element 221 is connected to the bottom of the blind hole 210, and the other end is connected to one end of the locking element. In this way, the locking element can be compressed into the blind hole 210 by squeezing the elastic element 221 and partially extended out of the blind hole 210 under the elastic force of the elastic element 221 to cooperate with the positioning hole 3211.

[0042] Reference Figure 2As one embodiment of the elastic locking part, the elastic element 221 can be a spring 3222, a compression spring, or other elastic components. Taking the elastic element 221 as a spring 3222 as an example, the locking element includes a ball 222, and the positioning hole 3211 is an arc-shaped concave surface. Its arc-shaped concave surface is adapted to the surface of the ball 222. The ball 222 can move relative to the blind hole 210 and partially protrude from the blind hole 210 to fit into the positioning hole 3211 (see reference). Figure 5 and 6 Once engaged, the rotating shaft 320 can be locked to maintain the setting angle between the ring 310 and the end cap 200. When the ring 310 is subjected to external force and rotates through the rotating shaft 320, the positioning hole 3211 will squeeze the ball 222, thereby causing the ball 222 to move into the blind hole 210 (during the movement, the spring 3222 is compressed). When the ring 310 and the end cap 200 reach a predetermined angle, the corresponding positioning hole 3211 on the rotating shaft 320 engages with the ball 222 again, locking the rotating shaft 320 again, so as to achieve the purpose of adjusting the angle between the hook 300 and the end cap 200.

[0043] As another embodiment of the elastic locking part 220 (without accompanying drawings), unlike the above embodiment, the locking member in this embodiment is a cylindrical insert rod, one end of which is connected to the spring 3222, and the other end can be inserted into the positioning hole 3211. The contact end between the insert rod and the positioning hole 3211 is set as an arc-shaped structure, or the positioning hole 3211 is set as the aforementioned arc-shaped concave surface, or both one end of the insert rod and the positioning hole 3211 are set as arc-shaped structures, so that when the rotating shaft 320 rotates, the positioning hole 3211 can squeeze the insert rod, allowing the rotating shaft 320 to rotate after the insert rod separates from the positioning hole 3211. The working principle of this embodiment is similar to that of the first embodiment described above, and will not be repeated here.

[0044] Based on the above embodiments, referring to Figure 2 , 3To facilitate the assembly and disassembly of the hook 300 and the end cap 200, the rotating shaft 320 includes a column 321 connected to the ring 310 and elastic telescopic rods 322 located at both ends of the column 321. The column 321 has a receiving hole 3212, and the elastic telescopic rods 322 are correspondingly located within the receiving hole 3212. Each elastic telescopic rod 322 includes a spring 3222 and two positioning shafts 3221 connected to both ends of the spring 3222. The connection ends of the positioning shafts 3221 and the spring 3222 are provided with connectors. 3221a, one end of its positioning shaft 3221 is connected to the end of the spring 3222 through the connector 3221a, and the other end extends out of the receiving hole 3212. The corresponding shaft groove 230 has insertion holes 231 at both ends that match the positioning shaft 3221. When the rotating shaft 320 is combined with the end cover 200, the column 321 is embedded in the shaft groove 230, and the two telescopic positioning shafts 3221 are correspondingly embedded in the insertion holes 231, thus realizing the detachable combination between the hook 300 and the end cover 200.

[0045] Based on the above embodiments, referring to Figure 4 To further enhance the firmness of the hook 300 folding onto the end cap 200, a magnetic groove 311 is provided at the end of the ring 310 away from the column 321. A magnetic attractor 4000 is provided in the corresponding magnetic groove 311. The magnetic attractor 4000 is also provided at the corresponding position on the end cap 200. In this way, when the hook 300 rotates around the pivot 320 and folds onto the end cap 200, the magnetic attractor 4000 on the ring 310 and the magnetic attractor 4000 on the end cap 200 are attracted to each other, thereby effectively enhancing the firmness of the hook 300 on the end cap 200.

[0046] In this embodiment, the magnetic component 400 is a magnet or other material that can be magnetically attracted. Of course, in order to make the hook 300 more secure after being folded and closed on the end cap 200, the magnetic component can also be replaced with Velcro or a snap fastener, which will not be described in detail here.

[0047] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
