Description
Hetero Material Combination Chopsticks (2) The present invention is related to the compositional structure of chopsticks, in particular, a combination chopstick of different materials consisting of different materials interfacing with each other. Press, combined chopsticks refer to chopsticks consisting of two separate sections of shaft butted, the main purpose of which is to reduce its storage length, and have the advantage of easy carrying. For example, the combined chopsticks disclosed in China's patent case No. M306838 are made by threaded docking to form their chopsticks Concave and convex structures (such as grooves or snap rings) are also more complicated in turning, especially when applied to the machining of metal shafts, which not only takes longer machining time, but also results in higher machining difficulty and increases its manufacturing cost if further requirements are required for its tight assembly. The chopsticks, as disclosed in our patent case No. M626900, are composed of a clamping structure composed of corresponding positioning bumps and positioning grooves. In addition, the telescopic environmentally friendly chopsticks disclosed in China's patent case No. M554750 are combined with the two-stage shaft of the chopstick body using a spring push top bead body to correspond to the positioning of the button in a certain hole. In addition, the composite titanium chopstick structure disclosed in China's patent case No. M569597 has a sticky glue applied to the interconnection of the two rods to form the chopstick body The uncured adhesive during the manufacturing process of its insertion is also easily pushed and displaced, resulting in poor attachment and bonding effect, and the cured adhesive is also prone to gradual brittleness or shrinkage with increasing use time, resulting in reduced bonding strength and loss of bonding function. In view of this, how to improve the above problems is the primary topic intended to be solved for this creation. The object of the present invention is to provide a combination chopsticks of different materials that can significantly reduce the manufacturing time and cost of a metal material shaft, and can additionally provide a different material combination chopstick with marking and quick recognition functions. To achieve the foregoing purposes, the invention provides a heteromaterial combination chopstick, comprising: a clamp rod, made of a metal material, and a set of holes formed at one end of the clamp rod; a grip rod, made of a non-metallic material, the grip rod forming a set of sockets at one end, and within the socket a first card lever portion; A combination component has a blocking portion, and a group portion and a sleeve portion are respectively protruded from two opposite sides of the blocking portion, the group portion is relatively inserted and fixed in the group hole, the sleeve portion is relatively inserted in the sleeve hole, and a second latch portion is provided on the sleeve portion and is mutually locked with the first latch portion. The outer diameter of the blocking portion is larger than the outer diameter of the group portion and the outer diameter of the sleeve portion, so that the blocking portion forms a blocking surface on the two opposite sides facing the clamping rod and the grip rod, the open end of the group hole and the open end of the sleeve hole are respectively abutted and positioned on the corresponding blocking surfaces, so that the combination can be used to combine and limit the clamping rod and the grip rod to form a chopstick body structure, and the outer peripheral surface of the blocking portion can further constitute a marking portion exposed on the surface of the chopstick body. Preferably, the first latch portion is composed of a rib surrounding the inner edge of the sleeve hole, and the second latch portion is composed of a groove surrounding the outer circumference of the sleeve portion, so that when the sleeve portion of the assembly is relatively inserted into the sleeve hole of the handle, the first latch portion and the second latch portion can be correspondingly latched together. Preferably, the sleeve hole is formed with a chamfered portion at an outer corner of its open end, so that when the handle is relatively pressed against the corresponding blocking surface with the open end of the sleeve hole, a groove can be formed between the handle and the assembly. Preferably, the sleeve portion is tapered toward its protruding direction. Preferably, an axial through hole is defined in the sleeve portion, so that the sleeve portion forms a hollow tube shape. Preferably, the assembly portion is formed in sequence with a connecting section and an inserting section in its protruding direction. The outer diameter of the connecting section is equal to or greater than the inner diameter of the assembly hole, so that the outer circumferential surface of the connecting section of the assembly portion can form a tight-fitting abutting engagement with the inner edge of the assembly hole, while the inserting section has a tapered shape that tapers toward its protruding direction. Furthermore, an annular groove is recessed on the outer circumferential surface of the connecting section, which is used to separate the connecting section into a first abutting surface and a second abutting surface that can respectively abut against the inner edge of the assembly hole. Preferably, the clamping rod is made of titanium, the gripping rod is made of plastic or wood, and the assembly is integrally injection-molded from plastic. The above-mentioned objects and advantages of the present invention can be more clearly understood from the following detailed description of the embodiments and the accompanying drawings. As shown in Figures 1 to 4, the present invention provides a combination of different materials chopsticks, which mainly consists of a clamping rod 11, a gripping rod 21, and an assembly 31 disposed between the clamping rod 11 and the gripping rod 21, which are connected to each other to form a chopstick body structure, wherein: The clamping rod 11 is made of metal. Preferably, the clamping rod 11 can be made of titanium metal in a long strip shape, which has the advantages of being non-toxic, lightweight, high in strength, corrosion-resistant and having a low thermal conductivity. The clamping rod 11 is used to form a clamping section of the chopstick body that can clamp food relative to the chopstick body, and a circular hole 12 is formed at one end of the clamping rod 11. The grip 21 is made of a non-metallic material in the shape of a long strip. The non-metallic material can be made of plastic or wood, etc., which has a surface anti-slip property better than that of metal, and is used to form a grip section of the chopstick body that can be grasped by a human hand. The grip 21 has a circular hole 22 formed at one end thereof, and the hole 22 has a chamfered portion 23 formed at the outer corner of the opening end, and a first latch portion 24 is formed on the inner edge of the hole 22 near the opening end; in this embodiment, the first latch portion 24 is composed of a rib surrounding the inner edge of the hole 22. The assembly 31 is integrally injection molded from a plastic material. The assembly 31 has a blocking portion 32, and a set portion 33 and a sleeve portion 34 are integrally formed on two opposite sides of the blocking portion 32, so that the set portion 33 and the sleeve portion 34 can respectively constitute the two ends of the assembly 31. The sleeve portion 34 is used to be inserted into the sleeve hole 22 of the handle 21, and a second latch portion 35 is provided on the sleeve portion 34 to be mutually locked with the first latch portion 24; in this embodiment, the second latch portion 35 is composed of a slot surrounding the outer circumference of the sleeve portion 34, so that when the sleeve portion 34 of the assembly 31 is relatively inserted into the sleeve hole 22 of the handle 21, the first latch portion 24 and the second latch portion 35 can be locked with each other. Together, the function of positioning the grip 21 is achieved, and the sleeve portion 34 is tapered toward its protruding direction, and an axial through hole 36 is defined in the sleeve portion 34, so that the sleeve portion 34 constitutes a hollow tube. The sleeve portion 34 is tapered and has the axial through hole 36, so that the sleeve portion 34 has better deformation elasticity, which can effectively improve the ease of assembly and disassembly between the sleeve portion 34 and the sleeve hole 22. The assembly portion 33 of the assembly member 31 is used to be relatively inserted and fixed in the assembly hole 12 of the clamping rod 11, and the assembly portion 33 is sequentially formed with a connecting section 37 and an insertion section 38 in the protruding direction thereof. The outer diameter of the connecting section 37 is equal to or greater than the inner diameter of the assembly hole 12, so that the outer peripheral surface of the connecting section 37 of the assembly portion 33 can form a tight-fitting abutting engagement with the inner edge of the assembly hole 12, and the insertion section 38 is tapered toward the protruding direction thereof. In addition, adhesive can be additionally applied between the assembly portion 33 and the assembly hole 12 to further enhance their bonding strength. In this embodiment, the connecting section 37 is further provided with an annular groove 39 on its outer circumferential surface. The annular groove 39 is used to separate the connecting section 37 to form a first abutting surface 371 and a second abutting surface 372 that can respectively abut against the inner edge of the assembly hole 12. In this way, the connecting section 37 on the assembly portion 33 can be closely abutted against the inner edge of the assembly hole 12 in sections, thereby further improving its bonding strength. The outer diameter of the blocking portion 32 of the assembly 31 is respectively larger than the outer diameter of the assembly portion 33 and the outer diameter of the sleeve portion 34, so that the blocking portion 32 can form an outwardly expanded circular ring shape, and a blocking surface 321 is formed on the two opposite sides of the blocking portion 32 facing the clamping rod 11 and the gripping rod 21. When the assembly hole 12 of the clamping rod 11 and the sleeve portion 22 of the gripping rod 21 are respectively engaged with the assembly portion 33 and the sleeve portion 34 of the assembly 31, the open end of the assembly hole 12 and the open end of the sleeve hole 22 will respectively abut and be positioned on the corresponding blocking surface 321, so that the assembly 31 can be used to combine and limit the clamping rod 11 and the gripping rod 21 to form the chopstick body structure. After they are assembled into the chopstick body, the outer peripheral surface of the blocking portion 32 can further constitute a marking portion exposed on the surface of the chopstick body. The invention composed of the above structure has the following advantages: 1. The heterogeneous material combination chopsticks provided by the present invention have a clamping rod 11 and a gripping rod 21 made of metal and non-metallic materials respectively, so that the clamping section constituting the chopstick body has the function of being hygienic and safe, while the gripping section has the function of being easy to hold and non-slip. 2. The present invention adopts a method of fixing the assembly portion 33 of the assembly 31 to the assembly hole 12 of the clamping rod 11 in a tight fit manner. At the same time, the assembly 31 is made of plastic material and has a slight elasticity, so that the bonding strength between the assembly 31 and the clamping rod 11 is not easy to loosen. The annular groove 39 is provided on the assembly section 37, and the assembly section 37 is further divided into a first abutting surface 371 and a second abutting surface 372 that can respectively abut against the inner edge of the assembly hole 12. In this way, the assembly section 37 on the assembly portion 33 can be segmented and tightly abutted against the inner edge of the assembly hole 12, so as to further enhance the bonding strength. 3. The grip 21 of the present invention is combined by aligning and engaging the first latch portion 24 in the sleeve hole 22 with the second latch portion 35 of the sleeve portion 34, and can be quickly disassembled to facilitate replacement of different grips 21. 4. The present invention simplifies the manufacturing process of the clamping rod 11 by connecting the assembly 31 to the clamping rod 11. That is, the clamping rod 11 made of metal material only needs to be formed with the assembly hole 12 at one end, and no additional turning process (such as turning a concave and convex structure such as a thread) is required. Therefore, the manufacturing time and cost of the clamping rod 11 made of metal material can be greatly reduced, making the clamping rod 11 made of metal material easier to manufacture. 5. In the heterogeneous material combination chopsticks provided by the present invention, when the assembly hole 12 of the clamping rod 11 and the sleeve hole 22 of the gripping rod 21 are respectively engaged with the assembly portion 33 and the sleeve portion 34 of the assembly member 31, the blocking surfaces 321 formed on both sides of the blocking portion 32 of the assembly member 31 not only provide a positioning function for the opening ends of the assembly hole 12 and the sleeve hole 22 to abut against each other, but also, after the chopsticks are assembled into the chopstick body, the outer peripheral surface of the blocking portion 32 can be directly formed and exposed on the surface of the chopstick body, thereby providing an additional marking function. Therefore, it is only necessary to further make the assembly member have a specific color to allow the user to intuitively and quickly identify the chopstick body (for example, to identify male and female chopsticks, or to identify the owner of the chopsticks). 6. The present invention further forms a chamfered portion 23 at the outer corner of the open end of the socket hole 22 of the handle 21. When the open end of the socket hole 22 of the handle 21 is relatively pressed against the corresponding blocking surface 321, a groove 41 is formed between the handle 21 and the assembly 31 on the surface of the chopstick body. The groove 41 not only serves as a reminder of the docking position, but also allows the user's fingernail to be inserted into the groove to apply force, making the handle 21 easy to disassemble and replace. The above embodiments are only used to illustrate the present invention, not to limit the present invention. Any replacement of equivalent elements should still fall within the scope of the present invention. In summary, it is clear to those skilled in the art that the present invention can indeed achieve the aforementioned objectives and complies with the provisions of the Patent Law, and therefore an application is filed in accordance with the law. 11: Clamping rod 12: Assembly hole 21: Grip 22: Socket hole 23: Chamfered portion 24: First latch portion 31: Assembly 32: Blocking portion 321: Blocking surface 33: Assembly portion 34: Socket portion 35: Second latch portion 36: Axial through hole 37: Assembly section 371: First abutting surface 372: Second abutting surface 38: Insertion section 39: Annular groove 41: Groove Figure 1 is an exploded view of the present invention.
