Based on the embodiments in the utility model, all other embodiments obtained by ordinary skilled person in the art without making creative labor belong to the scope of protection of the utility model.

[0031] The tea bar machine provided in the embodiment comprises a cabinet body and a cabinet door rotatably connected to the cabinet body, the cabinet body comprises a base, a side plate and a back plate, one of the side plate and the base is provided with a plurality of spaced buckle structures, and the other is provided with a first clamping groove fixedly installed with the buckle. The bottom of the side plate is provided with a folded edge portion bent inward to form a U-shaped structure, and the base is provided with a Z-shaped mounting cavity. The folded edge portion is fitted into the mounting cavity under the clamping cooperation between the buckle structure and the first clamping groove. In the embodiment, the U-shaped folded edge portion and the Z-shaped mounting cavity are arranged, and the clamping and fixing of the cabinet door, the cabinet buckle structure and the first clamping groove form a three-way limiting structure in the up-down, left-right and front-back directions to limit the displacement of the side plate in three directions at the same time, so as to realize the screw-free quick installation of the cabinet door, reduce the cost of the whole machine, and reduce the assembly and transportation difficulty of the whole machine. The reliability is further improved. In addition, the clamping and cooperation reduces the requirement for machining precision and position precision, so that the side plate and the base can be adaptively adjusted according to their respective machining conditions during assembly, and the product qualification rate is improved.

[0032] In detail, as shown in Figures 1-3 The tea bar machine provided in the embodiment comprises a cabinet body and a cabinet door rotatably connected to the cabinet body, the cabinet body comprises a base, a side plate and a back plate, one of the side plate and the base is provided with a plurality of spaced buckle structures, and the other is provided with a first clamping groove fixedly installed with the buckle. The bottom of the side plate is provided with a folded edge portion bent inward to form a U-shaped structure, and the base is provided with a Z-shaped mounting cavity. The folded edge portion is fitted into the mounting cavity under the clamping cooperation between the buckle structure and the first clamping groove. In the embodiment, the U-shaped folded edge portion and the Z-shaped mounting cavity are arranged, and the clamping and fixing of the cabinet door, the cabinet buckle structure and the first clamping groove form a three-way limiting structure in the up-down, left-right and front-back directions to limit the displacement of the side plate in three directions at the same time, so as to realize the screw-free quick installation of the cabinet door, reduce the cost of the whole machine, and reduce the assembly and transportation difficulty of the whole machine. The reliability is further improved. In addition, the clamping and cooperation reduces the requirement for machining precision and position precision, so that the side plate and the base can be adaptively adjusted according to their respective machining conditions during assembly, and the product qualification rate is improved.

[0033] In the embodiment, as shown in Figures 1-4As shown, the flange portion 121 specifically includes an inwardly extending first flange portion 1211, which is fixed to the bottom wall 1111 of the mounting cavity 111. A snap-fit ​​structure 130 or a first slot 140 is evenly distributed on the first flange portion 1211. Further, the snap-fit ​​structure 130 is provided on the bottom wall 1111 of the mounting cavity 111, and the first flange portion 1211 is correspondingly provided with the first slot 140. The flange portion 121 also includes an upwardly extending second flange portion 1212 connected to the first flange portion 1211. The second flange portion 1212 abuts against the side wall 1112 of the mounting cavity 111 when the side plate 120 is installed onto the base 110. The structural design of the first and second flange portions facilitates the rapid assembly of the side plate 120 and the base 110, while achieving surface contact between the side plate 120 and the base 110. It helps to disperse stress and reduce local stress concentration, thereby improving the stability of the contact part between the side plate 120 and the base 110, reducing the load on the base 110 and reducing potential damage caused by vibration. The second flange 1212 can abut against the side wall of the mounting cavity 111 to limit the displacement of the side plate 120 in the left and right directions. The first flange 1211 is fastened to the bottom wall 1111 by the snap-fit ​​structure 130 and the first slot 140 to realize the displacement of the side plate 120 in the up and down and front and back directions. It should be noted that the flange 121 can also improve the structural strength at the contact position between the base 110 and the side plate 120, especially the structural strength of the side plate 120 itself, so that the tea bar machine can maintain relatively high impact resistance and improve the overall structural strength of the tea bar machine.

[0034] In detail, such as Figure 3 and Figure 4As shown, a limiting structure 150 is also provided between the second flange 1211 and the side wall 1112 of the mounting cavity 111 to limit the vertical displacement of the side plate 120. The limiting structure 150 engages with the first slot 140 of the snap-fit ​​structure 130, forming a double limit on the vertical direction of the side plate 120, thus enhancing the reliability of the connection structure between the side plate 120 and the base 110. In one specific embodiment of this example, the limiting structure 150 includes a limiting part 151 located on the side wall 1112 of the mounting cavity 111 and a second slot 152 that engages with the limiting part 151. The second slot 152 is a through-slot structure evenly distributed on the second flange 1212. The engaging effect between the limiting part 151 and the second slot 152 secures the second flange 1212. The second flange 1212 is positioned on the side wall 1112 to limit its vertical displacement. Furthermore, the limiting part 151 is provided with multiple slots corresponding to the second slots 152, and its position is closer to the inside of the cabinet than that of the buckle structure 140. At the same time, the limiting part 151 and the buckle structure 140 are staggered, so that when the side plate and the base are fastened, they are subjected to forces in two directions. This allows for the application of loads in different directions, which can better balance and disperse stress, thereby improving the stability and deformation resistance of the whole structure. The uniform force in multiple directions can avoid local overload, thus making more effective use of the strength and toughness of the material, reducing stress concentration, reducing the risk of cracks or other damage, helping to reduce fatigue damage, and extending the service life of the tea bar machine.

[0035] Specifically, refer to Figure 3 The connection between the second flange 1212 and the first flange 1212 is an arc-shaped structure. The height of the second flange 1212 is less than or equal to the height of the side wall 1112 of the mounting cavity 111. In this embodiment, by setting the connection with an arc-shaped structure, the space is maximized, providing higher efficiency and practicality. It also reduces the sharp edges of the flange 121, reducing the possibility of damage to the flange 121 or the mounting cavity 111 caused by bumps. At the same time, it reduces the overall space occupied by the flange 121, so as to avoid uneven assembly due to manufacturing tolerances during the production of parts.

[0036] In this embodiment, as Figure 1 , Figure 3 and Figure 4As shown, the side panel 120 has a positioning flange 122 that bends toward the inside of the cabinet on the side near the cabinet door. The base 110 also has a plurality of guide structures 112 that cooperate with the positioning flange 122. The guide structures 112 are used to guide the side panel 120 to be installed on the base 100. Specifically, the guide structure 112 is fixed to the bottom wall 1111 of the mounting cavity 111 and extends upward in the vertical direction. The side panel 120 has a mounting opening 123 that is adapted to the guide structure 112, and the top of the guide structure 112 is higher than the top of the mounting cavity. By setting a guide structure 112 on the base 110 with a height higher than the mounting cavity, the side plate 120 first contacts the guide structure 112 through the positioning flange 122 during assembly, and the guide structure 112 performs preliminary positioning of the side plate 120 to ensure that the flange portion 121 of the side plate 120 can be accurately fixed to the mounting cavity 111. The first slot 140 and the second slot 152 are respectively aligned with the buckle structure 130 and the limiting portion 151 to prevent assembly misalignment. In the specific embodiment of this example, at least two guide structures 112 are provided, and they are located on the left and right sides near the cabinet door to improve the restriction of the displacement of the side plate 120 in the left and right directions.

[0037] In this embodiment, refer to Figure 4 The snap-fit ​​structure 130 includes a fixing part 131 fixed to the first slot 140 and a connecting part 132 connecting the fixing part 131 and extending downward. The base 110 is provided with a mounting groove 113 for fixing the connecting part 132. The fixing part 131 extends upward to the outside of the mounting groove 113. The fixing part 131 is used to cooperate with the first slot 140 and fasten onto the first flange 1211. Therefore, it needs to extend beyond the top opening of the mounting groove 111 and extend a certain distance to achieve assembly with the first slot 140, preventing assembly failure due to tolerances during processing. Specifically, the fixing part 131 includes a first limiting rib 1311 and a second limiting rib 1312 with opposite and symmetrically distributed fastening positions. When the first limiting rib 1311 and the second limiting rib 1312 cooperate with the first slot 140, they respectively engage. The first slot 140 is located on both the front and rear sides of the first slot, and the buckle structure 130 is an L-shaped structure on the top surface of the outer periphery of the base 110. The first slot 140 is a rectangular slot at the bottom of the side plate 120. When the side plate 120 is installed on the base 110, the fixing part 131 uses the first slot 140 to hold the side plate 120 above the base 100. In this embodiment, the restriction on the front and rear displacement of the side plate 120 is strengthened by setting two symmetrical and opposite fixing parts 131. The connecting parts 132 of the buckle structure 130 are all set in the mounting groove 113, forming a hidden design, which ensures the aesthetic appearance of the tea bar machine and improves the visual effect. At the same time, the mounting groove 113 protrudes downward, which increases the stress area of ​​the bottom surface of the base while enhancing the structural strength of the base 110, thereby improving the stability and deformation resistance of the base 110.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
