Description

Technical Field

[0001] The utility model belongs to the field of drinking water equipment, and particularly relates to a tea bar machine. Background Art

[0002] In recent years, with the improvement of living standards, the use of tea bar machines has become increasingly common. Currently, tea bar machines on the market typically consist of a cabinet and a back panel mounted on top of the cabinet. For ease of transportation, the back panel and cabinet are separated, requiring users to install the back panel on the cabinet after receiving the goods. Connectors are usually provided at the bottom of the back panel, which can be inserted into the grooves on the storage table at the top of the cabinet to achieve the connection between the back panel and the storage table. However, the grooves provide poor positioning for the connectors, and even slight force can easily cause the back panel mounted on the top of the cabinet to shake, resulting in a poor user experience. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide a tea bar machine to solve at least one of the above problems.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a tea bar machine, comprising a cabinet with a storage table on the top and a back panel mounted on the storage table, a plug-in protrusion on the bottom of the back panel, a plug-in slot on the top of the storage table, a limiting protrusion in the plug-in slot, the limiting protrusion extending upward from the inner bottom wall of the plug-in slot to form an annular plug-in gap for plugging the plug-in protrusion between the outer peripheral side of the limiting protrusion and the inner side wall of the plug-in slot, the plug-in protrusion is provided with a limiting slot opening downward, the top of the limiting protrusion extends out of the plug-in slot and is plugged into the limiting slot. This technical solution has the following technical effects:

[0005] The utility model provides a limiting protrusion in the plug-in groove at the top of the storage table, so that when the back panel is installed on the storage table, the plug-in protrusion at the bottom of the back panel is plugged into the annular plug-in gap on the storage table. At the same time, the limiting protrusion is plugged into the limiting groove of the plug-in protrusion. The plug-in structure between the back panel and the storage table increases the contact area between the storage table and the back panel, so that the storage table can support the outer wall of the plug-in protrusion in the horizontal direction through the inner side wall of the plug-in groove, and can also support the inner side wall of the limiting groove in the horizontal direction through the outer wall of the limiting protrusion. The height is greater than the depth of the insertion slot, so that the limiting protrusion can be inserted deeper into the back panel, increasing the contact area between the limiting protrusion and the limiting slot. Therefore, the limiting protrusion extending out of the insertion slot can enhance the supporting effect of the storage table on the back panel without deepening the depth of the insertion slot, making the installation of the back panel on the storage table more stable. When the back panel installed on the storage table is subjected to a lateral impact (such as a collision by the user), the limiting protrusion inserted into the back panel can stably support the back panel, avoiding violent shaking of the back panel, especially the top of the back panel, thereby improving the user experience.

[0006] In the tea bar machine described above, a plurality of longitudinally extending support ribs are provided on the inner sidewall of the limiting groove. When the limiting protrusion is plugged into the limiting groove, the support ribs abut against the outer sidewall of the limiting protrusion. The support ribs fill the gap between the inner sidewall of the limiting groove and the limiting protrusion, ensuring stable contact between the limiting groove and the limiting protrusion, avoiding a gap between the limiting protrusion and the limiting groove that could allow the limiting protrusion to wobble due to manufacturing errors, thereby reducing the amount of wobble of the back panel. The configuration of the limiting groove allows the plug-in protrusion to have a hollow annular structure. The longitudinally extending support ribs on the inner sidewall of the limiting groove enhance the strength of the plug-in protrusion and prevent it from breaking.

[0007] In the aforementioned tea bar machine, the plug-in protrusion is provided with a positioning hole that extends transversely through the plug-in protrusion, and the storage platform is provided with a latch and a mounting hole that extends transversely through the plug-in slot and the limiting protrusion. When the back panel is mounted on the storage platform, the latch sequentially passes through the opposing mounting hole and the positioning hole to limit the back panel. When the back panel is mounted on the storage platform, the positioning hole and the mounting hole are aligned so that they are coaxial. The latch can be passed through the mounting hole and the positioning hole in sequence to lock the back panel and the storage platform, thereby limiting the back panel in the horizontal and vertical directions. This simple structure can prevent the back panel from shaking vertically on the storage platform or freely disengaging from the storage platform, thereby ensuring the back panel is firmly installed on the storage platform.

[0008] In the above-mentioned tea bar machine, a guide rib located above the positioning hole is provided on the inner side wall of the limiting groove. The guide rib extends vertically to the highest point of the edge of the positioning hole and abuts against the outer side wall of the limiting protrusion. When the back panel is installed on the storage table, the outer side wall of the limiting protrusion abuts against the side of the guide rib, and the latch inserted into the positioning hole abuts against the end of the guide rib. By providing a guide rib located above the positioning hole on the inner side wall of the limiting groove, the latch can be guided and limited during insertion, preventing the end of the latch from tilting upward during insertion, that is, preventing the latch from being deflected during insertion and being unable to smoothly plug into the storage table and back panel, thereby reducing the difficulty of installing the latch. After the back panel is installed, the guide rib abuts against the outer side wall of the limiting protrusion, and can also fill the gap between the inner side wall of the limiting groove and the inner side wall of the limiting protrusion, thereby reducing the amount of shaking of the back panel.

[0009] In the tea bar machine described above, the latch includes a pin shaft and a head disposed at one end of the pin shaft. When the pin shaft is inserted into the mounting hole, the head shaft abuts against the outer wall of the storage table. The pin shaft has a circular cross-section. This circular cross-section allows the user to rotate the latch shaft 360 degrees around its central axis without affecting the connection between the pin shaft, the back panel, and the storage table when assembling the back panel and the storage table. This eliminates the need to rotate the latch shaft to align with the mounting hole, reducing insertion difficulty and improving installation efficiency.

[0010] In the tea bar machine described above, a guide bevel is provided on the end of the pin facing away from the head. The guide bevel is arranged around the central axis of the pin. This eliminates the need for precise alignment of the pin end with the mounting hole during installation. The guide bevel facilitates insertion of the pin into the mounting hole during installation, reducing assembly difficulty.

[0011] In the tea bar machine described above, a pull ring and a receiving slot for receiving the pull ring are provided on the side of the head facing away from the pin. The pull ring is rotatably connected to the head. When a user needs to insert or remove the latch, the pull ring is rotated until it extends out of the receiving slot. The user can then grasp the pull ring with their fingers to move the latch. After the latch is installed, the pull ring is rotated until it is stored in the receiving slot, thus preventing the pull ring from occupying space outside the latch.

[0012] In the above-mentioned tea bar machine, a coupler is also included. The coupler is installed on the storage table and protrudes from the top surface of the storage table. The top height of the limiting protrusion is higher than the top height of the coupler. The tea bar machine is relatively large in size. After receiving the tea bar machine, the user needs to unpack the package for assembly. Because the user usually disassembles the package by pouring out the components, the top height of the limiting protrusion is set to be higher than the top height of the coupler. When pouring out, the limiting protrusion can first contact the ground. The storage table and the limiting protrusion can form a triangular space with the ground to suspend the coupler, avoiding direct contact between the coupler and the ground, thereby preventing the coupler from being damaged by the impact of the ground or the impact of the ground on the coupler being transmitted to the glass cover, causing the glass cover of the storage table to break, thereby reducing the risk of damage to the coupler and the glass cover of the storage table.

[0013] In the above tea bar machine, both end surfaces of the limiting protrusion in the length direction are arc-shaped, so that the cross section of the limiting protrusion is waist-shaped, so as to facilitate the insertion of the limiting protrusion into the limiting groove.

[0014] In the tea bar machine described above, the stopper protrusion comprises a hollow annular sealing rib and a plurality of reinforcing ribs disposed within the annular sealing rib. The reinforcing ribs extend along the width of the stopper protrusion and are connected to two opposing inner sidewalls of the annular sealing rib. The coordinated structure of the annular sealing rib and the reinforcing ribs reduces the material and weight of the stopper protrusion while enhancing its strength. This ensures that, when the stopper protrusion is plugged into the stopper slot, it provides better support for the back panel and prevents breakage of the stopper protrusion.

[0015] The features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The utility model proposes a tea bar machine, comprising a cabinet with a storage table on the top and a back panel installed on the storage table, a plug-in protrusion is provided at the bottom of the back panel, a plug-in groove is provided at the top of the storage table, a limiting protrusion is provided in the plug-in groove, the limiting protrusion extends upward from the inner bottom wall of the plug-in groove to form an annular plug-in gap for plugging the plug-in protrusion between the outer peripheral side of the limiting protrusion and the inner side wall of the plug-in groove, a limiting groove with an opening downward is provided on the plug-in protrusion, and the top of the limiting protrusion extends out of the plug-in groove and is plugged into the limiting groove. The utility model provides a limiting protrusion in the plug-in groove at the top of the storage table, so that when the back panel is installed on the storage table, the plug-in protrusion at the bottom of the back panel is plugged into the annular plug-in gap on the storage table. At the same time, the limiting protrusion is plugged into the limiting groove of the plug-in protrusion. The plug-in structure between the back panel and the storage table increases the contact area between the storage table and the back panel, so that the storage table can support the outer wall of the plug-in protrusion in the horizontal direction through the inner side wall of the plug-in groove, and can also support the inner side wall of the limiting groove in the horizontal direction through the outer wall of the limiting protrusion. The height is greater than the depth of the insertion slot, so that the limiting protrusion can be inserted deeper into the back panel, increasing the contact area between the limiting protrusion and the limiting slot. Therefore, the limiting protrusion extending out of the insertion slot can enhance the supporting effect of the storage table on the back panel without deepening the depth of the insertion slot, making the installation of the back panel on the storage table more stable. When the back panel installed on the storage table is subjected to a lateral impact (such as a collision by the user), the limiting protrusion inserted into the back panel can stably support the back panel, avoiding violent shaking of the back panel, especially the top of the back panel, thereby improving the user experience.

[0036] Example 1:

[0037] A tea bar machine, such as Figures 1 to 8As shown, it includes a cabinet body and a back panel 200, a storage platform 100 is provided on the top of the cabinet body, and a plug-in slot 110 with an opening upward is provided on the top of the storage platform 100, and a limiting protrusion 120 is provided in the plug-in slot 110. The limiting protrusion 120 extends upward from the inner bottom wall of the plug-in slot 110 to form an annular plug-in gap 130 between the outer peripheral side of the limiting protrusion 120 and the inner side wall of the plug-in slot 110, and the top of the limiting protrusion 120 extends out of the plug-in slot 110, that is, the top height of the limiting protrusion 120 is higher than the top height of the plug-in slot 110. A plug-in protrusion 210 is provided at the bottom of the back panel 200, and a downward-opening limiting groove 211 is provided on the plug-in protrusion 210. The limiting groove 211 passes through the plug-in protrusion 210 and extends toward the interior of the back panel 200. When the back panel 200 is installed on the storage table 100, the plug-in protrusion 210 is plugged into the annular plug-in gap 130, and the outer side wall of the plug-in protrusion 210 is abutted against the inner side wall of the plug-in groove 110. At the same time, the limiting protrusion 120 is plugged into the limiting groove 211, and the inner side wall of the limiting groove 211 is abutted against the outer side wall of the limiting protrusion 120.

[0038] The utility model provides a limiting protrusion 120 in the plug-in groove 110 at the top of the storage table 100, so that when the back plate 200 is installed on the storage table 100, the plug-in protrusion 210 at the bottom of the back plate 200 is plugged into the annular plug-in gap 130 on the storage table 100. At the same time, the limiting protrusion 120 is plugged into the limiting groove 211 of the plug-in protrusion 210. The plug-in structure between the back plate 200 and the storage table 100 increases the contact area between the storage table 100 and the back plate 200, so that the storage table 100 can support the outer wall of the plug-in protrusion 210 in the horizontal direction through the inner side wall of the plug-in groove 110, and can also support the inner side wall of the limiting groove 211 in the horizontal direction through the outer wall of the limiting protrusion 120. The height of the protrusion 120 is greater than the depth of the insertion slot 110, so that the limiting protrusion 120 can be inserted deeper into the back panel 200, increasing the contact area between the limiting protrusion 120 and the limiting slot 211. Therefore, the limiting protrusion 120 extending out of the insertion slot 110 can enhance the supporting effect of the storage platform 100 on the back panel 200 without deepening the depth of the insertion slot 110, making the installation of the back panel 200 on the storage platform 100 more stable. When the back panel 200 installed on the storage platform 100 is subjected to a lateral impact (such as a collision by the user), the limiting protrusion 120 inserted into the back panel 200 can stably support the back panel 200, avoiding the back panel 200, especially the top of the back panel 200, from shaking violently, thereby improving the user experience.

[0039] like Figure 3As shown, in this embodiment, a plurality of support ribs 212 are provided on the inner side wall of the limiting groove 211, and the plurality of support ribs 212 extend longitudinally on the inner side wall of the limiting groove 211. When the limiting protrusion 120 is plugged into the limiting groove 211, the support ribs 212 abut against the outer side wall of the limiting protrusion 120. The support ribs 212 can fill the gap between the inner sidewall of the limiting groove 211 and the limiting protrusion 120, ensuring stable contact between the limiting groove 211 and the limiting protrusion 120, avoiding the gap between the limiting protrusion 120 and the limiting groove 211 that could allow the limiting protrusion 120 to wobble due to production and processing errors, thereby reducing the amount of wobble of the back plate 200. The arrangement of the limiting groove 211 allows the plug-in protrusion 210 to have a hollow annular structure. The support ribs 212 extending longitudinally on the inner sidewall of the limiting groove 211 can enhance the strength of the plug-in protrusion 210 and prevent the plug-in protrusion 210 from breaking. Preferably, multiple support ribs 212 are arranged at equal intervals on the inner sidewall of the limiting groove 211.

[0040] like Figure 5 As shown, a positioning hole 213 is provided on the plug-in protrusion 210, and the positioning hole 213 is arranged to pass through the plug-in protrusion 210 horizontally. A mounting hole 140 and a latch 300 are provided on the storage platform 100, and the mounting hole 140 passes through the side wall of the plug-in slot 110 and the limiting protrusion 120 horizontally. When the back panel 200 is installed on the storage platform 100, the positioning hole 213 is aligned with the mounting hole 140 so that the two are coaxial. The latch 300 can pass through the mounting hole 140 and the positioning hole 213 in sequence, so that the back panel 200 and the storage platform 100 are locked, so as to limit the back panel 200 in the horizontal and vertical directions. The simple structure can prevent the back panel 200 from shaking in the vertical direction on the storage platform 100 or from freely disengaging from the storage platform 100, thereby ensuring that the back panel 200 is firmly installed on the storage platform 100. Figure 6As shown, a guide rib 214 is provided on the inner wall of the limiting groove 211, and the guide rib 214 is located above the positioning hole 213. The guide rib 214 extends vertically downward from the top of the inner wall of the limiting groove 211 so that the end of the guide rib 214 is flush with the highest point of the edge of the positioning hole 213. When the back panel 200 is installed on the storage table 100, the outer wall of the limiting protrusion 120 is abutted against the side of the guide rib 214, and the pin 300 passed through the positioning hole 213 is abutted against the end of the guide rib 214. By providing a guide rib 214 located above the positioning hole 213 on the inner wall of the limiting groove 211, the pin 300 can be guided and limited during the process of plugging the pin 300, thereby preventing the end of the pin 300 from tilting upward during the plugging process, that is, preventing the pin 300 from being deflected during the plugging process and being unable to be smoothly plugged into the storage table 100 and the back panel 200, thereby reducing the difficulty of installing the pin 300. After the back panel 200 is installed, the guide rib 214 is abutted against the outer wall of the limiting protrusion 120, and can also fill the gap between the inner wall of the limiting groove 211 and the inner wall of the limiting protrusion 120, thereby reducing the amount of shaking of the back panel 200.

[0041] like Figure 2 As shown, the latch 300 includes a pin shaft 310 and a head 320 provided at one end of the pin shaft 310. When the back panel 200 and the storage table 100 are assembled, the pin shaft 310 is inserted into the mounting hole 140 and the positioning hole 213. The head 320 of the latch 300 is located outside the mounting hole 140 and the positioning hole 213, and is against the outer wall of the storage table 100, so as to install and position the latch 300 during installation. The axial cross-section of the pin shaft 310 is circular, so that when the user assembles the back panel 200 and the storage table 100 by themselves, any rotation of the pin 300 will not affect the connection between the pin shaft 310 and the back panel 200 and the storage table 100. There is no need to rotate the pin 300 to align with the mounting hole 140, which reduces the difficulty of insertion and improves installation efficiency. Preferably, a guide bevel 311 is provided at the end of the pin 310 away from the head 320. The guide bevel 311 is arranged around the central axis of the pin 310 so that the end of the pin 310 does not need to be precisely aligned with the mounting hole 140 during installation. The guide bevel 311 can assist the pin 310 in being plugged into the mounting hole 140 during the installation process, thereby reducing the difficulty of assembly.

[0042] like Figure 7 and Figure 8As shown, a receiving groove 321 is provided on the side of the head 320 of the latch 300 facing away from the pin shaft 310, and a pull ring 330 is provided in the receiving groove 321. The pull ring 330 is rotatably connected to the head 320 and can be stored in the receiving groove 321 or extended out of the receiving groove 321 by rotation. When the user needs to insert or pull out the latch 300, the pull ring 330 is rotated to extend out of the receiving groove 321. The user can hold the pull ring 330 with his fingers to drive the latch 300 to move, which is convenient and simple to operate. After the latch 300 is installed, the pull ring 330 is rotated to a position where it is stored in the receiving groove 321 to avoid the pull ring 330 occupying the space outside the latch 300.

[0043] In this embodiment, the storage table 100 includes a top plate 150 and a glass cover plate 160 covering the top plate 150. The tea bar machine also includes a coupler 400. The coupler 400 passes through the top plate 150 and the glass cover plate 160 in sequence to be electrically connected to the kettle on the storage table for boiling water. That is, the coupler 400 is arranged on the storage table 100, and the coupler 400 protrudes from the top surface of the storage table 100. The top height of the limiting protrusion 120 is higher than the top height of the coupler 400. The tea bar machine is large in size. After receiving the tea bar machine, the user needs to unpack it for assembly. Because the user usually disassembles the packaging by pouring out the various components, the top height of the limiting protrusion 120 is set to be higher than the top height of the coupler 400, so that when pouring out, the limiting protrusion 120 of the storage table will first contact the ground. A triangular space can be formed between the storage table 100 and the limiting protrusion 120 and the ground to allow the coupler 400 to be suspended in the air, preventing the coupler 400 from directly contacting the ground, thereby preventing the coupler 400 from being damaged by the impact of the ground or the impact of the ground on the coupler 400 being transmitted to the glass cover 160, causing the glass cover 160 of the storage table 100 to break, thereby reducing the risk of damage to the coupler 400 and the glass cover 160 of the storage table 100.

[0044] In this embodiment, the two end surfaces of the limiting protrusion 120 in the longitudinal direction are arc-shaped, so that the cross-section of the limiting protrusion 120 is waist-shaped, which facilitates the insertion of the limiting protrusion 120 into the limiting groove 211. Preferably, the limiting protrusion 120 includes a hollow annular sealing rib 121 and a plurality of reinforcing ribs 122. The reinforcing ribs 122 are arranged in the annular sealing rib 121. Each reinforcing rib 122 extends along the width direction of the limiting protrusion 120 and is respectively connected to the two opposite inner side walls of the annular sealing rib 121. The structure of the annular sealing rib 121 and the reinforcing ribs 122 cooperates to reduce the material and weight of the limiting protrusion 120 while enhancing the strength of the limiting protrusion 120, avoiding bending and deformation of the limiting protrusion 120, so that after the limiting protrusion 120 is inserted into the limiting groove 211, the supporting effect on the back plate 200 is better, preventing the limiting protrusion 120 from breaking.

[0045] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
