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] A tea bar machine generally includes a cabinet body and a back plate installed on the top of the cabinet body. For the convenience of transportation, at present, the tea bar machines on the market are of a split structure with the cabinet body. After the user receives the tea bar machine, tools such as screwdrivers are required to install the back plate onto the cabinet body by themselves. The installation of the back plate is difficult, so that when the user installs it by themselves, it is easy to be not installed in place, causing problems such as water leakage, and the user experience is poor.

[0003] To solve the above problems, a prior art discloses a quick installation and disassembly structure. A locking member for limiting a plug-in member is arranged inside a slot, and a locking hole is arranged on the side wall of the plug-in member. Specifically, the locking member includes a sliding member and a reset member. The sliding member is located in the slot, and by pressing the pressing part of the sliding member, the sliding member is controlled to move inside the slot. One end of the reset member is connected to one side of the sliding member, and the other end abuts against the side wall of the slot. The reset member is preferably arranged as a reset spring to facilitate automatic locking of the installed back plate, with low installation difficulty and reduced workload of the user.

[0004] However, the above solution has a relatively complex structure, many components, and high requirements for the accuracy and strength of the accessories of the overall structure. It is easily affected by manufacturing tolerances, resulting in problems such as jamming and appearance defects during installation. At the same time, when the back plate is inserted and installed, it is still not convenient enough, resulting in poor user experience.

[0005] Therefore, there is an urgent need for a technical solution with convenient installation, small complexity of accessories, and higher appearance consistency at present. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a tea bar machine to solve at least one of the above problems.

[0007] To solve the above technical problems, the utility model adopts the following technical scheme: A tea bar machine includes a placement table and a back plate. A plug-in member is arranged at the bottom of the back plate, and a plug-in slot for the plug-in member to be inserted is arranged at the top of the placement table. An elastic buckle is arranged on the plug-in member, and an installation hole penetrating the side wall of the plug-in slot is arranged at the rear side of the placement table. When the back plate is installed on the placement table, the elastic buckle is clamped with the installation hole to limit the back plate. The technical scheme has the following technical effects:

[0008] The utility model provides an elastic buckle on the connector at the bottom of the back panel, and provides a mounting hole that horizontally penetrates the side wall of the plug-in slot on the storage platform, so that when the user installs the back panel on the storage platform, he only needs to plug the connector into the mounting slot, and the elastic buckle on the side of the connector can automatically engage with the mounting hole on the side wall of the plug-in slot through deformation, so as to lock the back panel in the vertical direction. The installation is convenient and simple, and the back panel is prevented from being freely separated from the storage platform when subjected to upward force (such as collision by the user), thereby ensuring the stable installation of the back panel on the storage platform; when the user needs to remove the back panel from the storage platform, he only needs to press the elastic buckle in the mounting hole to make the elastic buckle deform and retract into the plug-in slot, and then the back panel can be lifted upward to realize the disassembly of the back panel. The overall complexity of the disassembly and assembly structure is low, the installation operation is more convenient, and the user experience is improved.

[0009] In the above tea bar machine, the elastic buckle includes a longitudinally extending elastic pressure plate and a clamping protrusion arranged on one side of the elastic pressure plate, the upper end of the elastic pressure plate is connected to the plug-in component, and when the elastic buckle is clamped with the mounting hole, the top of the clamping protrusion abuts against the inner wall of the mounting hole. The longitudinal extension of the elastic pressure plate allows the elastic buckle to have a larger deformation amount, so that the elastic buckle can be deformed, avoiding the elastic buckle from breaking when installing or removing the back plate, and extending the service life of the elastic buckle.

[0010] In the above tea bar machine, the longitudinal section of the snap-fit protrusion is triangular, so that the snap-fit protrusion is tilted downward toward the mounting surface of the mounting hole, and a pressing protrusion is provided on the mounting surface, which is vertically arranged away from the pressing surface of the snap-fit protrusion. The locking protrusion is arranged downwardly inclined toward the mounting surface of the mounting hole. During the plug-in process of the plug-in piece and the plug-in slot, the inclined mounting surface abuts against the inner side wall of the plug-in slot, and the inner side wall of the plug-in slot pushes the mounting surface, so that the elastic pressure plate is bent and deformed to automatically avoid the side wall of the plug-in slot. When the plug-in piece and the plug-in slot are plugged in place, the elastic pressure plate is reset to make the locking protrusion snap into the mounting hole, so as to realize the clamping between the elastic buckle and the mounting hole. During the entire installation process, the user does not need to press the elastic buckle, and the user can install smoothly and labor-saving. A pressing protrusion is provided on the mounting surface, and the pressing protrusion has a pressing surface away from the locking protrusion. The pressing surface is vertically arranged. When the plug-in piece and the plug-in slot are plugged in place, the pressing protrusion is located in the mounting hole to shorten the distance between the end of the mounting hole and the elastic buckle. The user's finger does not need to extend into the mounting hole for a long distance to push the elastic buckle to deform, so that the user presses the elastic buckle to unlock the elastic buckle and the mounting hole, thereby improving the user's operating experience.

[0011] In the above-mentioned tea bar machine, the pressing protrusion is provided with a first arc-shaped guiding surface, and the first arc-shaped guiding surface is connected between the bottom surface and the pressing surface of the pressing protrusion. When the plug-in part and the plug-in slot are plugged, the bottom of the inner wall of the plug-in slot will abut against the first arc-shaped guiding surface of the pressing protrusion and slide along the first arc-shaped guiding surface towards the pressing surface, so as to push the pressing protrusion to avoid the side wall of the plug-in slot, preventing the pressing protrusion from abutting against the top of the placement table and hindering the installation of the plug-in part and the plug-in slot, making the installation smoother.

[0012] In the above-mentioned tea bar machine, the clamping protrusion has an abutting surface at its top, and a second arc-shaped guiding surface is connected between the abutting surface and the installation surface. When disassembling the back panel, the end of the side wall of the installation hole abuts against the second arc-shaped guiding surface and slides along the second arc-shaped guiding surface towards the installation surface, so that the disengagement of the clamping protrusion from the installation hole is smoother, and the user operation is more labor-saving.

[0013] In the above-mentioned tea bar machine, the plug-in part is a ring-shaped plugging protrusion, and the ring-shaped plugging protrusion is provided with an avoidance notch for accommodating the elastic pressing plate, and there is a deformation gap between the two sides of the elastic pressing plate and the inner wall of the avoidance notch. The avoidance notch accommodates the elastic pressing plate and reserves a deformation gap on both sides of the elastic pressing plate to prevent the plug-in part from hindering the deformation of the elastic pressing plate, enabling the elastic pressing plate to have a greater deformation amount, preventing the elastic pressing plate from breaking, and prolonging the service life.

[0014] In the above-mentioned tea bar machine, the ring-shaped plugging protrusion is provided with positioning ribs, and the positioning ribs vertically extend on the outer side wall of the ring-shaped plugging protrusion and abut against the inner side wall of the plug-in slot. The positioning ribs can enhance the strength of the ring-shaped plugging protrusion, prevent the ring-shaped plugging protrusion from bending, deforming or breaking, and prolong the service life of the ring-shaped plugging protrusion. When the ring-shaped plugging protrusion is plugged into the plug-in slot, the positioning ribs can abut against the inner side wall of the plug-in slot to fill the gap between the ring-shaped plugging protrusion and the inner side wall of the plug-in slot, making the installation between the plug-in part and the plug-in slot tighter and preventing the back panel from shaking.

[0015] In the above-mentioned tea bar machine, a drain pipe communicating with the inside of the back panel is further provided at the bottom of the back panel, and the ring-shaped plugging protrusion surrounds the drain pipe. When the water circuit inside the back panel leaks, the water flow can be discharged from the drain pipe out of the back panel, and the ring-shaped plugging protrusion surrounds the drain pipe to hide the drain pipe inside the ring-shaped plugging protrusion, so that the ring-shaped plugging protrusion can shield the drain pipe, making it more beautiful.

[0016] In the above-mentioned tea bar machine, an avoidance groove is provided on the inner side wall of the plug-in slot, and the avoidance groove is located above the installation hole to avoid the elastic buckle during the installation of the back panel. When the plug-in part and the plug-in slot are plugged, the avoidance groove can avoid the end of the elastic buckle to prevent the clamping protrusion from abutting against the top of the placement table and hindering the installation of the plug-in part and the plug-in slot, making the installation smoother.

[0017] In the above-mentioned tea bar machine, a groove is provided on the rear side of the placement table, and the mounting hole is arranged in the groove. The setting of the groove can accommodate the part of the elastic buckle protruding from the mounting hole, so as to prevent the elastic buckle from protruding from the surface of the placement table, prevent the protruding part of the elastic buckle from being collided by external force and cause the disconnection of the mounting hole of the elastic buckle, ensure the stable locking of the back plate on the placement table, and at the same time be more beautiful, ensuring the consistency of the appearance.

[0040] Embodiment 1:

[0041] A tea bar machine, as Figures 1 to 9 shown, includes a cabinet body and a back plate 100. A placement table 200 is provided at the top of the cabinet body. An insertion slot 210 with an upward opening is provided at the top of the placement table 200. An installation hole 220 is provided at the rear side of the placement table 200. The installation hole 220 horizontally penetrates the rear side wall of the insertion slot 210 to communicate the outside and the insertion slot 210. A plug-in member 300 is provided at the bottom of the back plate 100. An elastic buckle 400 is provided on the plug-in member 300. When the back plate 100 is installed on the placement table 200, the bottom surface of the back plate 100 abuts against the top surface of the placement table 200. The plug-in member 300 is inserted into the insertion slot 210, and the elastic buckle 400 on the side of the plug-in member 300 is clamped with the installation hole 220 to limit the back plate 100 in the vertical direction through the elastic buckle 400.

[0042] In the present utility model, an elastic buckle 400 is provided on the plug-in connector 300 at the bottom of the back panel 100, and an installation hole 220 penetrating the side wall of the plug-in groove 210 horizontally is provided on the storage table 200. When a user installs the back panel 100 on the storage table 200, the plug-in connector 300 only needs to be inserted into the installation groove, and the elastic buckle 400 on the side of the plug-in connector 300 can be automatically clamped with the installation hole 220 on the side wall of the plug-in groove 210 through deformation, so as to lock the back panel 100 in the vertical direction. The installation is convenient and simple, and it is avoided that the back panel 100 is freely separated from the storage table 200 when receiving an upward force (such as the collision of a user), ensuring the stable installation of the back panel 100 on the storage table 200; when the user needs to remove the back panel 100 from the storage table 200, only need to press the elastic buckle 400 in the installation hole 220 to make the elastic buckle 400 deform and retract into the plug-in groove 210, then the back panel 100 can be lifted upward to realize the removal of the back panel 100. The overall complexity of the disassembly and assembly structure is low, the installation operation is more convenient, and the user experience is improved.

[0043] As Figure 3 shown, in this embodiment, the elastic buckle 400 includes an elastic pressing plate 410 and a clamping protrusion 420. The upper end of the elastic pressing plate 410 is connected to the plug-in connector 300, the lower end of the elastic pressing plate 410 extends longitudinally downward, the clamping protrusion 420 is arranged at the bottom of one side of the elastic pressing plate 410 and protrudes from the side surface of the elastic pressing plate 410. When the back panel 100 is installed on the storage table 200, the clamping protrusion 420 extends into the installation hole 220, and the top of the clamping protrusion 420 abuts against the inner wall of the installation hole 220 to prevent the clamping protrusion 420 from moving upward, realizing the clamping of the elastic buckle 400 with the installation hole 220, and further realizing the locking and limiting of the back panel 100. The longitudinally extending arrangement of the elastic pressing plate 410 enables the elastic buckle 400 to have a large deformation amount, so that the elastic buckle 400 can deform, avoiding the fracture of the elastic buckle 400 when the user installs or disassembles the back panel 100, and prolonging the service life of the elastic buckle 400. As Figure 5As shown, preferably in this embodiment, the longitudinal section of the snap projection 420 is triangular, and the mounting surface 422 of the snap projection 420 facing the mounting hole 220 is inclined downward. During the insertion process of the connector 300 into the insertion slot 210, the inclined mounting surface 422 abuts against the inner sidewall of the insertion slot 210, and the inner sidewall of the insertion slot 210 pushes the mounting surface 422, causing the elastic pressing plate 410 to bend and deform to automatically avoid the sidewall of the insertion slot 210. When the connector 300 is inserted into the insertion slot 210 in place, the elastic pressing plate 410 resets, so that the snap projection 420 is snapped into the mounting hole 220, and the clamping between the elastic snap 400 and the mounting hole 220 can be realized. During the entire installation process, there is no need for the user to press the elastic snap 400, and the user's installation is smooth and labor-saving. A pressing projection 430 is provided on the mounting surface 422. The pressing projection 430 has a pressing surface 431 facing away from the snap projection 420, and the pressing surface 431 is vertically arranged. When the connector 300 is inserted into the insertion slot 210 in place, the pressing projection 430 is located in the mounting hole 220 to shorten the distance between the end of the mounting hole 220 and the elastic snap 400. The user's finger does not need to extend into the mounting hole 220 for a long distance to push the elastic snap 400 to deform, so that the user can press the elastic snap 400 to unlock the elastic snap 400 and improve the user's operation experience.

[0044] In this embodiment, a first arc-shaped guiding surface 432 is provided on the pressing projection 430. The first arc-shaped guiding surface 432 is connected between the bottom surface and the pressing surface 431 of the pressing projection 430. When the connector 300 and the insertion slot 210 are inserted, the bottom of the inner wall of the insertion slot 210 will abut against the first arc-shaped guiding surface 432 of the pressing projection 430 and slide along the first arc-shaped guiding surface 432 towards the pressing surface 431 to push the pressing projection 430 to avoid the sidewall of the insertion slot 210, preventing the pressing projection 430 from abutting against the top of the storage table 200 and hindering the installation of the connector 300 into the insertion slot 210, making the installation smoother.

[0045] The snap projection 420 has an abutting surface 421, and the abutting surface 421 is located at the top of the snap projection 420 for abutting against the inner wall of the mounting hole 220 when the elastic snap 400 is snapped with the mounting hole 220. A second arc-shaped guiding surface 423 is connected between the abutting surface 421 and the mounting surface 422. When disassembling the back panel 100, the end of the sidewall of the mounting hole 220 abuts against the second arc-shaped guiding surface 423 and slides along the second arc-shaped guiding surface 423 towards the mounting surface 422, making the disengagement of the snap projection 420 from the mounting hole 220 smoother and the user's operation more labor-saving.

[0046] The plug-in member 300 in this embodiment is a hollow annular plug-in protrusion 310. An avoidance notch 311 is provided on the annular plug-in protrusion 310. The elastic pressing plate 410 is arranged in the avoidance notch 311. The two sides of the elastic pressing plate 410 do not contact the annular plug-in protrusion 310, so as to form a deformation gap 312 between the elastic pressing plate 410 and the inner side wall of the avoidance notch 311. The avoidance notch 311 accommodates the elastic pressing plate 410 and reserves a deformation gap 312 on both sides of the elastic pressing plate 410, so as to prevent the plug-in member 300 from hindering the deformation of the elastic pressing plate 410, enabling the elastic pressing plate 410 to have a larger deformation amount, avoiding the elastic pressing plate 410 from breaking, and prolonging the service life.

[0047] Positioning ribs 320 are provided on the outer side wall of the annular plug-in protrusion 310. There are multiple positioning ribs 320, and the multiple positioning ribs 320 are arranged in parallel and extend vertically on the annular plug-in protrusion 310. The positioning ribs 320 can enhance the strength of the annular plug-in protrusion 310, avoid the annular plug-in protrusion 310 from bending, deforming or breaking, and prolong the service life of the annular plug-in protrusion 310. When the annular plug-in protrusion 310 is plugged into the plug-in slot 210, the positioning ribs 320 can abut against the inner side wall of the plug-in slot 210 to fill the gap between the annular plug-in protrusion 310 and the inner side wall of the plug-in slot 210, making the installation between the plug-in member 300 and the plug-in slot 210 tighter and preventing the backboard 100 from shaking.

[0048] As Figure 6 shown, in this embodiment, a drain pipe 110 is further provided at the bottom of the backboard 100. The drain pipe 110 is communicated with the inside of the backboard 100. When water leaks in the waterway inside the backboard 100, the water flow can be discharged from the drain pipe 110 out of the backboard 100. The annular plug-in protrusion 310 is arranged around the drain pipe 110 to hide the drain pipe 110 inside the annular plug-in protrusion 310, so that the annular plug-in protrusion 310 can block the drain pipe 110 and make it more beautiful.

[0049] In this embodiment, as Figure 9 shown, an avoidance groove 211 is further provided on the inner side wall of the plug-in slot 210. The avoidance groove 211 is located at the opening of the plug-in slot 210 and is directly above the installation hole 220. When the plug-in member 300 is plugged into the plug-in slot 210, the avoidance groove 211 can avoid the end of the elastic buckle 400, so as to prevent the clamping protrusion 420 from abutting against the top of the placement table 200 and hindering the installation of the plug-in member 300 and the plug-in slot 210, making the installation smoother.

[0050] As Figure 7As shown in the figure, a groove 230 recessed into the interior of the placement table 200 is provided on the rear side surface of the placement table 200. The mounting hole 220 is provided in the groove 230. The groove 230 can accommodate the part of the clamping protrusion 420 of the elastic buckle 400 that extends out of the mounting hole 220, so as to prevent the elastic buckle 400 from protruding from the surface of the placement table 200, and prevent the protruding part of the clamping protrusion 420 from being collided by an external force, resulting in the disconnection of the mounting hole 220 of the elastic buckle 400, ensuring the stable locking of the back plate 100 on the placement table 200, and at the same time being more beautiful, ensuring the consistency of the appearance.

[0051] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. Any technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
