AI Technical Summary
When storing existing splicing chopsticks, they need to separate two sections of structures to occupy more space. The part used to pick up food in the lower section is easily contaminated, and the stability and strength of the connecting structure are insufficient, resulting in shaking at the connection.
A portable splicing chopstick was designed, using the upper chopstick body as a tubular structure and the lower chopstick body as the main body part and the connecting head. The connection was achieved through the tight fit of the middle part, and the main body part of the lower chopstick body was inserted into the tube of the upper chopstick body. In the cavity, the elastic deformation of plastic materials and the tight fit of wooden or bamboo materials are used to ensure connection stability and avoid direct contact with the chopstick tip through structural design.
It reduces storage space requirements, avoids bacterial contamination on the hands, improves portability, and uses a clever structural design to prevent the connection from shaking, ensuring higher safety and hygiene.

Description
Technical Field
[0001] The utility model belongs to the technical field of chopsticks, and specifically relates to portable chopsticks, in particular to two-section spliced portable chopsticks suitable for limited space. Background Art
[0002] Spliced chopsticks and telescopic chopsticks are two main structural forms of portable chopsticks. Compared with telescopic chopsticks, the advantage of spliced chopsticks is that the structure is relatively simple. Existing spliced chopsticks mainly connect two sections of the structure together by threaded connection or plug-in to form a pair of chopsticks. For example, the disposable spliced chopsticks disclosed in the Chinese utility model patent with publication number CN206630411U include a first chopstick body, a second chopstick body, a first connecting member and a second connecting member, the first chopstick body is fixedly connected to the first connecting member, the second chopstick body is fixedly connected to the second connecting member, the first connecting member and the second connecting member are detachably connected, and the detachable connection between the first connecting member and the second connecting member is a plug-in connection or a threaded connection.
[0003] For another example, the hygienic spliced chopsticks disclosed in the Chinese utility model patent with publication number CN214258873U include a coaxially arranged hand-held connecting rod (upper structure) and a food-holding connecting rod (lower structure), the bottom end of the hand-held connecting rod is connected to the top end of the food-holding connecting rod, the bottom end of the hand-held connecting rod is provided with a connecting protrusion, the top end of the food-holding connecting rod is provided with a connecting hole, and the hand-held connecting rod is detachably connected to the food-holding connecting rod through the cooperation of the connecting protrusion and the connecting hole.
[0004] The above-mentioned existing spliced chopsticks have the following shortcomings: 1. When storing, the connection between the upper and lower sections of the structure needs to be disconnected and the chopsticks need to be placed as two independent components, which requires more storage space. 2. When storing, the lower section used for picking up food is exposed to the outside and is easily contaminated. 3. Technical information on how to ensure the connection strength of the connection structure, how to make the connection structure stable, and how to prevent the connection from shaking is not disclosed. Summary of the invention
[0005] The purpose of the utility model is to provide an innovative structural solution to address the above-mentioned deficiencies of existing spliced chopsticks, which not only ensures the stability of the connection structure between the two sections and prevents the connection from loosening, but also cleverly utilizes the structural relationship to achieve multiple functions of one part.
[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a portable spliced chopsticks, including an upper chopstick body and a lower chopstick body, characterized in that the upper chopstick body is a tubular structure with at least one end open, and the lower chopstick body includes a main body and a connecting head, and the lower end of the main body is the chopstick tip. An intermediate part is provided between the connecting head and the main body, and the radial dimension of the intermediate part is larger than the radial dimension of the tube cavity of the upper chopstick body. The maximum radial dimension of the connecting head is tightly matched with the radial dimension of the tube cavity of the upper chopstick body, the maximum radial dimension of the main body is tightly matched with the radial dimension of the tube cavity of the upper chopstick body, and the length of the main body is less than or equal to the length of the tube cavity of the upper chopstick body.
[0007] When the spliced chopsticks are used, the connecting head of the lower chopstick body is inserted into the tube cavity of the upper chopstick body and tightly matched therewith to achieve connection, and then the lower chopstick body and the upper chopstick body are combined to form a whole chopstick with a combined length. When stored, the main body of the lower chopstick body is inserted into the tube cavity of the upper chopstick body, and the lower chopstick body is fixed in the tube cavity of the upper chopstick body through the tight fit between the two.
[0008] Furthermore, the upper chopstick body is a single body structure formed by thermoplastic molding of plastic material, and the lower chopstick body is a single body structure made of wood or bamboo material. The tube cavity of the upper chopstick body and the lower chopstick body including the main body and the connecting head are tightly matched based on the elastic deformation of the plastic material supplemented by the elastic deformation of the wood material or bamboo material.
[0009] Specifically, the upper chopstick body is made of PP material. The ratio of the wall thickness to the outer diameter of the tubular structure is 0.08-0.12.
[0010] As an option, the upper chopstick body is a circular tube structure, the main body of the lower chopstick body near the middle part is a cylindrical structure, the diameter of the cylindrical structure is larger than the inner diameter of the circular tube structure. The entire connecting head or the part near the middle part is a cylindrical structure with the same diameter as the cylindrical structure of the main body.
[0011] As another option, the upper chopstick body is a square tube structure, the main body of the lower chopstick body near the middle part is a square column structure, and the cross-sectional size of the square column structure is larger than the inner cavity cross-sectional size of the square tube structure. The entire connecting head or the part near the middle part is a square column structure with the same cross-sectional size as the square column structure of the main body.
[0012] Furthermore, the middle portion is a columnar structure, and its cross-sectional dimensions are the same as the tubular outer dimensions of the upper chopstick body.
[0013] Preferably, any cross-sectional shape of the upper chopstick body and the lower chopstick body is circular, the middle portion is a cylindrical structure, the upper chopstick body is a circular tube structure, and the diameter of the middle portion is the same as the outer diameter of the upper chopstick body.
[0014] Furthermore, the lower end of the main body of the lower chopstick body is a chopstick tip with a nearly conical structure that gradually shrinks from top to bottom.
[0015] Furthermore, a tight-fitting section connected to the middle part is provided on the upper part of the main body of the lower chopstick body. The tight-fitting section is a columnar structure that fits tightly with the tubular cavity of the upper chopstick body. The part from the lower end of the tight-fitting section to the tip of the chopsticks is a conical or quasi-conical structure that gradually shrinks from top to bottom.
[0016] Optionally, the main body of the lower chopstick body is a cone-shaped or approximately cone-shaped structure that gradually shrinks from top to bottom, and the upper end of the main body of the lower chopstick body is tightly matched with the tube cavity of the upper chopstick body.
[0017] Furthermore, the main body of the lower chopstick body and the connecting head are tightly matched with the tube cavity of the upper chopstick body and the contact surface is provided with a convex-concave matching structure.
[0018] The beneficial effects of the utility model are as follows: 1. Unlike the existing spliced chopsticks, which have two sections of chopstick bodies that are stored separately, the two sections of the spliced chopsticks of the utility model are stored together, which can reduce the occupied space by nearly half, and the portability is doubled. 2. During the splicing process, the user does not need to directly touch the tip of the chopsticks, that is, the end of the chopsticks that touches the food, thereby avoiding cross-contamination of bacteria or dirt on the hands. At the same time, before use, the tip of the chopsticks is cleverly stored in the tube cavity, completely isolated from the external environment, effectively preventing the attachment of pollutants such as dust and bacteria, and is safer and more hygienic.

[0024] The following is a further explanation of the structure and assembly method of the portable spliced chopsticks claimed by the present invention in conjunction with the accompanying drawings.
[0025] Reference Figure 1-5The disposable spliced chopsticks described in the utility model include an upper chopstick body 2 and a lower chopstick body 1. Both the upper chopstick body 2 and the lower chopstick body 1 are monomer structures. The upper chopstick body 2 is a straight through tubular structure with openings at both ends.
[0026] The lower chopstick body is divided into three functional parts from top to bottom, namely, a connecting head 12, a middle part 13, and a main body 11, wherein the main body 11 constitutes the lower half of the chopsticks after splicing, and its lower end is the chopstick tip, which is used to directly contact food. The middle part 13 is used to limit the connection between the upper chopstick body 2 and the lower chopstick body 1 during splicing and storage, and is used for holding during storage and splicing. The connecting head 12 is used as a connecting structure to connect the upper chopstick body 2 and the lower chopstick body 1 during splicing.
[0027] The following description is based on the example that both the upper chopstick body 2 and the lower chopstick body 1 have a circular structure.
[0028] The diameter of the upper chopstick body 2 is 7.3 mm, the wall thickness is 0.7 mm, and the ratio of the wall thickness to the outer diameter is 0.096.
[0029] The diameter of the middle part 13 is larger than the inner diameter of the tube cavity of the upper chopstick body 2. The connecting head 12 includes a cylindrical tight fitting section 121, the diameter of which is slightly larger than the inner diameter of the tube cavity of the upper chopstick body, so that it is tightly matched with the inner diameter of the tube cavity of the upper chopstick body, and the upper end of the main body also includes a cylindrical tight fitting section 111, the diameter of which is slightly larger than the inner diameter of the tube cavity of the upper chopstick body, so that it is tightly matched with the inner diameter of the tube cavity of the upper chopstick body, and the length L1 of the main body 11 is less than or equal to the length L2 of the tube cavity of the upper chopstick body 2.
[0030] The diameter of the middle portion 13 is equal to the outer diameter of the upper chopstick body 2. In the spliced or stored state, the side profile of the middle portion 13 is aligned with the side profile of the upper chopstick body 2.
[0031] In the storage state, the main body 11 of the lower chopstick body 1 is inserted into the tube cavity of the upper chopstick body from one end opening of the upper chopstick body 2, and the tight fitting section 111 at the upper end of the main body 11 of the lower chopstick body is tightly fitted with the inner wall of the tube cavity of the upper chopstick body 2 to achieve the tight connection between the upper chopstick body 2 and the lower chopstick body 1, and the lower chopstick body 1 and the upper chopstick body 2 are combined to form a combination body with a length close to half of that in the use state. The main body of the lower chopstick body 1 is stored and maintained in the tube cavity of the upper chopstick body 2.
[0032] When it is needed, hold the middle part 13 of the lower chopstick body, pull the main part 11 of the lower chopstick body out of the tube cavity of the upper chopstick body, then turn the lower chopstick body, insert the connecting head 12 from one end opening of the upper chopstick body 2 into the tube cavity of the upper chopstick body, and the tight fitting section 121 of the connecting head 12 is tightly fitted with the inner wall of the tube cavity of the upper chopstick body 2 to complete the fastening connection between the upper chopstick body 2 and the other end of the lower chopstick body 1. Then, the lower chopstick body 1 and the upper chopstick body 2 are combined to form a whole pair of chopsticks with a combined length for use.
[0033] Compared with traditional telescopic chopsticks or other types of spliced chopsticks, the spliced chopsticks of the utility model do not need to directly touch the tip of the chopsticks, that is, the end of the chopsticks that touches the food, during the splicing process, thereby avoiding cross-contamination of bacteria or dirt on the hands. At the same time, before use, the tip of the chopsticks is cleverly stored in the tube cavity, completely isolated from the external environment, effectively preventing the attachment of pollutants such as dust and bacteria, and is safer and more hygienic.
