Abstract
Description
Technical Field
[0001] This utility model relates to a mortise and tenon joint module, and more particularly to a mortise and tenon joint module used as an assembly toy, which belongs to the category of toys. Background Technology
[0002] There are various types of assembly toys in the current technology, and the assembly methods are also different. Some use interlocking joints, connecting through friction, while others use magnetic force. Magnetic connections generally result in a more regular structure, but if things get messy, they will stick together and become a clump, unable to maintain a fixed shape. Interlocking joints have high requirements for size; if they are too tight, they won't fit, and if they are too loose, they won't connect properly. They will also loosen with repeated use. Furthermore, interlocking joints are generally one-to-one, and when multiple parts are connected, they cannot support each other, which does not enhance the stability of the connection. In addition, the variety of connections cannot be guaranteed, resulting in limited functionality and low fun. Utility Model Content
[0003] The purpose of this utility model is to provide a mortise and tenon joint module to solve the problems of multiple parts of assembled toys not being able to support each other and the connection method being unstable in the prior art.
[0004] To solve the above problems, the mortise and tenon joint module involved in this utility model adopts the following technical solution: a mortise and tenon joint module,

[0039] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model; that is, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0040] In the specific embodiment 1 of the mortise and tenon joint module involved in this utility model, Figure 1 and Figure 2In this mortise and tenon joint module, there are several first square overlapping strips 1. A first rectangular notch 2 is provided on one side of each first square overlapping strip 1. Since the first square overlapping strip 1 is square, its end face is square. The side length of the first square overlapping strip 1 refers to the side length of its end face. The depth of the first rectangular notch 2 is half the side length of the first square overlapping strip 1. The notch extends from one side to the opposite side; that is, it is continuous and open, extending to three adjacent faces. The notch is U-shaped, consisting of two side walls and a bottom wall. The depth of the notch refers to the distance from the bottom of the notch to the opening. The width of the first rectangular notch 2 is the same as the side length of the first square overlapping strip 1. The width of the first rectangular notch 2 refers to the distance between the two side walls of the notch. The distance between adjacent side walls of two adjacent first rectangular notches 2 is equal to the width of the first rectangular notch 2. The distance between the end face of the first square overlap strip 1 and the nearest sidewall of the nearest first rectangular notch 2 is the same as the width of the first rectangular notch 2. This distance refers to the extension direction of the first square overlap strip.
[0041] Furthermore, such as Figure 2 As shown, the sidewalls of the first rectangular notch 2 are inclined, meaning the distance between the two sidewalls at the bottom is less than the distance at the opening. Furthermore, the angle between the sidewall of the first rectangular notch 2 and the side of the first square overlapping strip where the notch is located is 60°.
[0042] Furthermore, the sidewalls of the first rectangular notch 2 have flared chamfers 7 at both ends. That is, the first rectangular notch 2 has chamfers at the two sides it extends to, and these two sides are the two adjacent sides of the side where the first rectangular notch is set.
[0043] In this embodiment, the sidewall of the first rectangular notch 2 is a slope. In other embodiments, it can also be a plane, that is, the sidewall is perpendicular to the sidewall of the first square overlapping strip where the notch is set.
[0044] In the second specific embodiment of the mortise and tenon joint module involved in this utility model, Figure 3 and Figure 4 In China, combined Figure 1 and Figure 2 The difference between this embodiment and Embodiment 1 is that it also includes several second square overlapping strips 3, and second rectangular notches 4 are provided on two sides of the second square overlapping strips 3. These two sidewalls can be two adjacent sidewalls, such as... Figure 2 As shown, it can also be two opposite sidewalls, such as Figure 3As shown, the side length of the second square overlap strip 3 is equal to the side length of the first square overlap strip in embodiment 1. Furthermore, the width and depth of the second rectangular notch 4 are the same as those of the first rectangular notch 2. Similarly, the distance between adjacent sidewalls of two adjacent second rectangular notches 4 is equal to the width of the second rectangular notch 4. Here, "adjacent" refers to the two closest second rectangular notches, regardless of whether they are on the same side. The distance between the end face of the second square overlap strip 3 and the nearest sidewall of the nearest second rectangular notch 4 is the same as the width of the second rectangular notch 4. This distance refers to the distance along the extension direction of the second square overlap strip.
[0045] In the specific embodiment 3 of the mortise and tenon joint module involved in this utility model, Figure 5 In China, combined Figure 1 , Figure 2 as well as Figure 3 and Figure 4 The difference between this embodiment and Embodiment 2 is that it also includes several third-square overlapping strips 5. Third rectangular notches 6 are evenly distributed on the three sides of each third-square overlapping strip 5. The side length of the third-square overlapping strip 5 is equal to the side length of the first square overlapping strip in Embodiment 1 and the second square overlapping strip in Embodiment 2. Furthermore, the width and depth of the third rectangular notches 6 are the same as those of the first rectangular notches 2. Similarly, the distance between the adjacent sidewalls of two adjacent third rectangular notches 6 is equal to the width of the third rectangular notch 6. Here, "adjacent" refers to the two closest third rectangular notches, regardless of whether they are on the same side. The distance between the end face of the third square overlapping strip 5 and the nearest sidewall of the nearest third rectangular notch 6 is the same as the width of the third rectangular notch 6. This distance refers to the distance along the extension direction of the third-square overlapping strip.
[0046] In the accompanying drawings of the above embodiments, the first square strip, the second square strip, and the third square strip all have a specific number of rectangular notches. In other embodiments, the number of rectangular notches can be selected as needed. In the above embodiments, the case of having only one rectangular notch is not given. The first square strip may have only one first rectangular notch.
[0047] In the above embodiments, the first overlapping strip, the second overlapping strip, and the third overlapping strip have the same structure as some and different structures. The difference here refers to the different number of rectangular notches. For the second overlapping strip and the third overlapping strip, there are also different arrangements of rectangular notches.
[0048] In addition to the assembly method mentioned in the beneficial effects, this utility model also has other assembly methods such as... Figures 6-18 The method shown is a usage method and is used to help explain the function of this utility model.
[0049] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
