Description

Technical Field

[0001] The utility model relates to chopsticks, in particular to disposable tower groove self-locking assembled bamboo chopsticks. Background Art

[0002] A Chinese patent with announcement number CN213551041U discloses a pair of chopsticks, including a grip rod and a food clamp rod, wherein the grip rod is provided with a screw hole, and an outer side wall at one end of the food clamp rod is provided with an external thread that matches the screw hole. With the utility model, the grip rod and the food clamp rod are stably connected and are not easy to fall off. The above scheme uses a threaded connection method to connect the grip rod and the food clamp rod together to form chopsticks. On the one hand, it is cumbersome to twist the grip rod and the food clamp rod relative to each other during use. On the other hand, the processing cost of the thread is high, especially for bamboo chopsticks, which are prone to defects such as broken processing parts during processing. In view of the above defects, it is necessary to design a disposable tower groove self-locking assembly bamboo chopsticks. Utility Model Content

[0003] The purpose of the utility model is to provide a disposable tower groove self-locking assembled bamboo chopsticks, which can be quickly installed by direct plug-in and docking. Compared with the processing of threads, the shapes of the components of the device are regular, the processing is simple and convenient, and the yield rate is high.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a disposable tower groove self-locking assembled bamboo chopsticks, including a tower-shaped tenon rod and a tapered groove mortise tube, the top of the tower-shaped tenon rod is sequentially provided with a first frustum, a first cylindrical block and a second frustum from bottom to top, the inner side of the tapered groove mortise tube is sequentially provided with a second tapered hole, a first cylindrical cavity and a first tapered hole from top to bottom, the first frustum matches the shape of the first tapered hole, the second frustum matches the shape of the second tapered hole, the first cylindrical block forms an interference fit with the first cylindrical cavity, and the diameter of the first cylindrical block is between the diameters of the top circle and the bottom circle of the first frustum.

[0005] The utility model is further improved as follows:

[0006] Furthermore, a second cylindrical block is provided at the upper end of the second truncated cone, and the diameter of the second cylindrical block is not greater than the top circle diameter of the second truncated cone.

[0007] Furthermore, the tapered groove mortise tube is also provided with a second cylindrical cavity, which is arranged at the upper end of the second tapered hole, and the shape of the second cylindrical cavity matches that of the second cylindrical block.

[0008] Furthermore, the outer surface of the first cylindrical block is provided with serrations.

[0009] Furthermore, the inner surface of the first cylindrical cavity is provided with grooves, and the saw teeth fit in the grooves.

[0010] Furthermore, the bottom circle diameter of the second truncated cone is not greater than the diameter of the first cylindrical block.

[0011] Furthermore, the tower-shaped tenon rod is conical.

[0012] Compared with the prior art, the disposable tower groove self-locking assembled bamboo chopsticks, when used, hold the tower-shaped tenon rod and the tapered groove mortise tube in both hands for insertion. Since the diameter of the first cylindrical block is between the top circle and bottom circle diameters of the first truncated cone, a protrusion that blocks the first cylindrical block from slipping out downward is formed at the connection between the first cylindrical cavity and the first tapered hole. At this time, the first cylindrical block and the first cylindrical cavity form an interference fit and dock together. The first truncated cone and the second truncated cone on both sides of the first cylindrical block are respectively tightly attached to the first tapered hole and the second tapered hole, so that the tower-shaped tenon rod and the tapered groove mortise tube automatically coincide with each other, and the tower-shaped tenon rod and the tapered groove mortise tube are tightly connected, not easy to slip out, and not shaking. The device has a simple structure and can be quickly installed by direct insertion and docking. Compared with the processing of threads, the shapes of the components of the device are regular, the processing is simple and convenient, and the yield rate is high.
