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 usually includes a cabinet body and a back plate installed on the top of the cabinet body. For the convenience of transportation, currently, the tea bar machines on the market have a split structure with the cabinet body. Users need to install the back plate on the cabinet body by themselves after receiving the goods. Usually, a plug-in part is arranged at the bottom of the back plate to realize the installation between the back plate and the placement table by plugging the plug-in part into the groove of the placement table on the top of the cabinet body. However, the inner side wall of the groove of the placement table abuts against the peripheral side of the plug-in part to limit the back plate. The contact area between the plug-in part and the groove is small, resulting in a poor limiting effect of the groove on the plug-in part. Slight force can easily cause the back plate to shake, and the user experience is poor. Content of the Utility Model

[0003] 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.

[0004] To solve the above technical problem, the utility model adopts the following technical scheme: A tea bar machine includes a cabinet body with a placement table at the top and a back plate installed on the placement table. An installation groove is provided at the top of the placement table, a ring-shaped plug-in part is provided at the bottom of the back plate, a positioning protrusion is provided on the inner bottom wall of the installation groove, and an annular slot is formed between the outer peripheral side of the positioning protrusion and the inner side wall of the installation groove. The ring-shaped plug-in part is plugged into the annular slot. The technical scheme has the following technical effects:

[0005] In the present utility model, by providing positioning protrusions in the installation groove, an annular slot for accommodating the annular plug-in part at the bottom of the back panel can be formed between the outer peripheral side of the positioning protrusion and the inner side wall of the installation groove. When the back panel is installed on the storage table, the annular plug-in part is inserted into the annular slot, and the storage table supports the outer side wall of the annular plug-in part through the inner side wall of the installation groove to limit the annular plug-in part. At the same time, the storage table can also support the inner side wall of the annular plug-in part through the positioning protrusion to further limit the annular plug-in part. The positioning protrusion increases the contact area between the storage table and the annular plugging protrusion, that is, increases the supporting area of the storage table for the annular plugging protrusion in the horizontal direction, making the limiting effect of the storage table on the annular plug-in part better, and the installation of the back panel on the storage table more stable, preventing the back panel installed on the storage table from shaking when subjected to a horizontal force (such as a slight collision by the user), and improving the user experience. And by setting the structure of the bottom of the back panel for plugging into the installation groove as a hollow annular plugging protrusion, it can be avoided that the annular plugging protrusion shrinks or warps due to internal structures such as cross ribs during the production process, ensuring the uniform thickness of the annular plugging protrusion, and effectively avoiding assembly difficulties caused by the deformation of the annular plugging protrusion, reducing the assembly difficulty of the back panel and the storage table, and improving the assembly efficiency.

[0006] In the above-mentioned tea bar machine, the width of the annular slot is the same as the thickness of the annular plug-in part, so that the inner side wall of the annular plug-in part abuts against the outer side wall of the positioning protrusion, and the outer side wall of the annular plug-in part abuts against the inner side wall of the installation groove. When the annular plug-in part is inserted into the annular slot, the inner side wall of the annular plug-in part is in contact with and abuts against the outer side wall of the positioning protrusion, and the outer side wall of the annular plug-in part is in contact with and abuts against the inner side wall of the installation groove, avoiding the formation of a gap that causes slight shaking of the back panel between the annular plug-in part and the positioning protrusion or between the annular plug-in part and the inner side wall of the installation groove, making the supporting effect of the storage table on the back panel in the horizontal direction better, and the installation of the back panel more stable and reliable.

[0007] In the above-mentioned tea bar machine, the thickness of the annular connector gradually decreases from top to bottom, and the outer side walls of the positioning protrusions and the inner side walls of the installation grooves are both inclined to cooperate with the annular connector. By setting the annular connector to have a structure with a gradually decreasing thickness from top to bottom, and setting the opposite side walls of the annular slot to cooperate with the annular connector, when the user installs the back panel onto the storage table, at the initial stage of the insertion of the annular connector into the annular slot, the width of the top opening of the annular slot is greater than the bottom thickness of the annular connector. There is no need to precisely align the annular connector and the annular slot. After the annular connector is partially inserted into the annular slot, the inner side wall of the inclined installation groove and the outer side wall of the positioning protrusion can guide the installation of the annular connector, so that the annular connector and the annular slot can be quickly inserted, reducing the installation difficulty for the user and improving the user's assembly experience. After the back panel and the storage table are installed, the outer side wall of the inclined positioning protrusion and the inner side wall of the installation groove can increase the supporting area of the storage table for the annular connector, making the installation of the back panel on the storage table more stable and reliable.

[0008] In the above-mentioned tea bar machine, the annular connector includes an annular rib extending downward and a plurality of positioning ribs provided on the annular rib. The positioning ribs longitudinally extend on the outer side wall of the annular rib and abut against the inner side wall of the installation groove. The positioning ribs can enhance the strength of the annular rib, prevent the annular rib from bending, deforming or breaking, and extend the service life of the annular connector. When the annular rib is inserted into the annular slot, the positioning ribs can abut against the inner side wall of the installation groove to fill the gap between the annular rib and the inner wall of the annular slot, making the installation of the annular connector and the annular slot more tight.

[0009] In the above-mentioned tea bar machine, the height of the positioning protrusion is less than the depth of the installation groove, so as to form a first installation gap between the bottom surface of the back panel installed on the storage table and the top surface of the positioning protrusion. The first installation gap reserves some installation allowances between the back panel and the storage table to prevent the positioning protrusion from being too high and lifting the back panel upward, resulting in the back panel not being installed in place.

[0010] In the above-mentioned tea bar machine, the height of the inner side wall of the installation groove is greater than the height of the annular connector, so as to form a second installation gap between the bottom of the annular connector inserted into the annular slot and the inner bottom wall of the annular slot. The second installation gap can reserve some installation allowances between the back panel and the storage table, preventing the bottom surface of the back panel from not abutting against the top surface of the storage table due to the annular connector being too long, and ensuring that the back panel can be installed in place.

[0011] In the above-mentioned tea bar machine, a limiting member and a first limiting hole that transversely penetrates the side wall of the installation groove and the positioning protrusion are provided on the storage table, a second limiting hole that is aligned with the first limiting hole is provided on the annular plug-in member, and the limiting member transversely penetrates the first limiting hole and the second limiting hole to limit the back plate. When the back plate is installed on the storage table, the second limiting hole is aligned with the first limiting hole, and the limiting member transversely penetrates the first limiting hole and the second limiting hole to limit the back plate in the vertical direction. When the back plate is hit upward, the annular plug-in member will not be disengaged from the annular slot, thereby ensuring the stable installation of the back plate on the storage table.

[0012] In the above-mentioned tea bar machine, the side of the storage table protrudes into the installation groove to form a receiving groove for accommodating the end of the limiter on the side of the storage table away from the installation groove, and the annular plug-in is provided with an avoidance groove for avoiding the protrusion. When the limiter is plugged into the storage table and the annular plug-in, the end of the limiter is located in the receiving groove, so that the limiter is accommodated by the receiving groove, avoiding the end of the limiter protruding from the outer wall of the storage table and occupying too much space, thereby avoiding the protrusion of the limiter from the storage table to affect the placement of the tea bar machine against the wall, and facilitating the user to place and use it.

[0013] In the above tea bar machine, the positioning protrusion is integrally formed on the placement table, so that the positioning protrusion is a hollow structure with an opening downward. By integrally forming the positioning protrusion and the placement table, the placement table is a hollow structure, which reduces the weight and production materials of the placement table, facilitates the opening of the first limiting hole on the placement table, and reduces the assembly steps of the placement table.

[0014] In the tea bar machine, two annular connectors are provided, and the two annular connectors are symmetrically arranged on both sides of the bottom surface of the back plate. The two annular connectors are symmetrically arranged on both sides of the bottom surface of the back plate, which reduces the material of the annular connectors while ensuring that the annular connectors can stably support the back plate, so that the force on both sides of the back plate is more uniform and the installation is more stable.

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

[0029] A tea bar machine proposed by the present utility model includes a cabinet body with a placement table at the top and a back plate installed on the placement table. The top of the placement table is provided with an installation groove, and the bottom of the back plate is provided with an annular plug-in part. A positioning protrusion is provided on the inner bottom wall of the installation groove. An annular slot is formed between the outer peripheral side of the positioning protrusion and the inner side wall of the installation groove. The annular plug-in part is inserted into the annular slot. By providing a positioning protrusion in the installation groove in the present utility model, an annular slot for accommodating the annular plug-in part at the bottom of the back plate can be formed between the outer peripheral side of the positioning protrusion and the inner side wall of the installation groove. When the back plate is installed on the placement table, the annular plug-in part is inserted into the annular slot. The placement table supports the outer side wall of the annular plug-in part through the inner side wall of the installation groove to limit the annular plug-in part. At the same time, the placement table can also support the inner side wall of the annular plug-in part through the positioning protrusion to further limit the annular plug-in part. The positioning protrusion increases the contact area between the placement table and the annular plug-in protrusion, that is, increases the support area of the placement table for the annular plug-in protrusion in the transverse direction, making the limiting effect of the placement table on the annular plug-in part better, and the installation of the back plate on the placement table more stable, preventing the back plate installed on the placement table from shaking when receiving a transverse force (such as a slight collision by the user), and improving the user experience. And by setting the structure of the bottom of the back plate for plugging into the installation groove as a hollow annular plug-in protrusion, it can be avoided that the annular plug-in protrusion shrinks or warps and deforms due to internal structures such as cross ribs during the production process, ensuring the uniform thickness of the annular plug-in protrusion, and effectively avoiding assembly difficulties caused by the deformation of the annular plug-in protrusion, reducing the assembly difficulty of the back plate and the placement table, and improving the assembly efficiency.

[0035] Embodiment 1:

[0036] A tea bar machine, as Figures 1 to 7 shown, includes a cabinet body and a back plate 100. A placement table 200 is provided at the top of the cabinet body. An upward-opening installation groove 210 is provided at the top of the placement table 200. A positioning protrusion 220 is provided in the installation groove 210. The positioning protrusion 220 is provided on the inner bottom wall of the installation groove 210 and extends upward, so as to form an annular slot 230 surrounding the positioning protrusion 220 between the outer peripheral side of the positioning protrusion 220 and the inner side wall of the installation groove 210. An annular insertion member 300 is provided at the bottom of the back plate 100. When the back plate 100 is installed on the placement table 200, the annular insertion member 300 is inserted into the annular slot 230.

[0037] In the present utility model, by providing a positioning protrusion 220 in the installation groove 210, a circular slot 230 for accommodating the bottom annular connector 300 of the back plate 100 can be formed between the outer peripheral side of the positioning protrusion 220 and the inner side wall of the installation groove 210. When the back plate 100 is installed on the storage table 200, the annular connector 300 is inserted into the circular slot 230, and the storage table 200 supports the outer side wall of the annular connector 300 through the inner side wall of the installation groove 210 to limit the annular connector 300. At the same time, the storage table 200 can also support the inner side wall of the annular connector 300 through the positioning protrusion 220 to further limit the annular connector 300. The positioning protrusion 220 increases the contact area between the storage table 200 and the annular insertion protrusion, that is, increases the lateral support area of the storage table 200 for the annular insertion protrusion, making the limiting effect of the storage table 200 on the annular connector 300 better, and the installation of the back plate 100 on the storage table 200 more stable, preventing the back plate 100 installed on the storage table 200 from shaking when subjected to a lateral force (such as a slight collision by the user), and improving the user experience. And by setting the structure of the bottom of the back plate 100 for inserting the installation groove 210 as a hollow annular insertion protrusion, it is possible to avoid shrinkage or warping deformation of the annular insertion protrusion due to internal structures such as cross ribs during the production process, ensure the uniform thickness of the annular insertion protrusion, and thus effectively avoid assembly difficulties caused by deformation of the annular insertion protrusion, reduce the assembly difficulty of the back plate 100 and the storage table 200, and improve the assembly efficiency.

[0038] As Figure 7 shown, the width of the circular slot 230 is the same as the thickness of the annular connector 300. When the annular connector 300 is inserted into the circular slot 230, the inner side wall of the annular connector 300 is in contact with and abuts against the outer side wall of the positioning protrusion 220, and the outer side wall of the annular connector 300 is in contact with and abuts against the inner side wall of the installation groove 210, avoiding the formation of a gap that causes slight shaking of the back plate 100 between the annular connector 300 and the positioning protrusion 220 or between the annular connector 300 and the inner side wall of the installation groove 210, making the support effect of the storage table 200 on the back plate 100 in the horizontal direction better, and the installation of the back plate 100 more stable and reliable.

[0039] Preferably, the thickness of the annular connector 300 gradually decreases from top to bottom, that is, the longitudinal section of the annular connector 300 is an inverted trapezoid. The outer side wall of the positioning protrusion 220 is inclined obliquely upward. At the same time, the inner side wall of the mounting groove 210 opposite to the positioning protrusion 220 is inclined obliquely upward, so that the longitudinal section of the annular slot 230 is also an inverted trapezoid to cooperate with the annular connector 300. By setting the annular connector 300 to have a structure with a gradually decreasing thickness from top to bottom and setting the opposite side walls of the annular slot 230 to cooperate with the annular connector 300, when the user installs the back plate 100 on the storage table 200, at the initial stage of inserting the annular connector 300 into the annular slot 230, the top opening width of the annular slot 230 is greater than the bottom thickness of the annular connector 300. There is no need to precisely align the annular connector 300 and the annular slot 230. After the annular connector 300 is partially inserted into the annular slot 230, the inner side wall of the inclined mounting groove 210 and the outer side wall of the positioning protrusion 220 can guide the installation of the annular connector 300, so that the annular connector 300 and the annular slot 230 can be quickly inserted, reducing the installation difficulty of the user and improving the user's assembly experience. After the back plate 100 and the storage table 200 are installed, the outer side wall of the inclined positioning protrusion 220 and the inner side wall of the mounting groove 210 can increase the supporting area of the storage table 200 for the annular connector 300, making the installation of the back plate 100 on the storage table 200 more stable and reliable.

[0040] As Figure 3 shown, the annular connector 300 includes an annular rib 310 and positioning ribs 320. The annular rib 310 is annular and extends downward. There are multiple positioning ribs 320, and the multiple positioning ribs 320 extend vertically on the outer side wall of the annular rib 310, so that the multiple positioning ribs 320 are arranged in parallel. The positioning ribs 320 can enhance the strength of the annular rib 310, prevent the annular rib 310 from bending, deforming or breaking, and extend the service life of the annular connector 300. When the annular rib 310 is inserted into the annular slot 230, the positioning ribs 320 can fill the gap between the annular rib 310 and the inner wall of the annular slot 230 by abutting against the inner side wall of the mounting groove 210, making the installation of the annular connector 300 and the annular slot 230 tighter.

[0041] As Figure 7As shown in the figure, in this embodiment, the height of the positioning protrusion 220 is less than the depth of the installation groove 210, that is, the top surface of the positioning protrusion 220 is lower than the notch of the installation groove 210. 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 on the periphery of the notch of the installation groove 210. The annular connector 300 is inserted into the annular slot 230. A first installation gap 410 is formed between the top surface of the positioning protrusion 220 and the bottom surface of the back plate 100. The first installation gap 410 reserves a part of the installation allowance between the back plate 100 and the placement table 200, so as to prevent the positioning protrusion 220 from pushing up the back plate 100 due to the excessive height of the positioning protrusion 220, resulting in the back plate 100 not being installed in place.

[0042] The height of the inner side wall of the installation groove 210 is greater than the height of the annular connector 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 on the periphery of the notch of the installation groove 210. The annular connector 300 is inserted into the annular slot 230. A second installation gap 420 is formed between the bottom of the annular connector 300 and the inner bottom wall of the annular slot 230. The second installation gap 420 can also reserve a part of the installation allowance between the back plate 100 and the placement table 200, to prevent the bottom surface of the back plate 100 from not abutting against the top surface of the placement table 200 due to the excessive length of the annular connector 300, and ensure that the back plate 100 can be installed in place.

[0043] As Figure 2 shown in the figure, in this embodiment, a first limiting hole 240 is provided on the placement table 200. The first limiting hole 240 horizontally penetrates the side wall of the installation groove 210 and the positioning protrusion 220. A second limiting hole 330 is provided on the annular connector 300. When the back plate 100 is installed on the placement table 200, the second limiting hole 330 is aligned with the first limiting hole 240, and the limiting member 260 horizontally passes through the first limiting hole 240 and the second limiting hole 330 to limit the back plate 100 in the vertical direction. When the back plate 100 is subjected to an upward collision, the annular connector 300 will not come off from the annular slot 230, ensuring the stable installation of the back plate 100 on the placement table 200. Preferably, the positioning protrusion 220 in this embodiment is integrally formed on the placement table 200, so that the positioning protrusion 220 has a hollow structure with an opening downward. By integrally forming the positioning protrusion 220 with the placement table 200, the placement table 200 has a hollow structure, reducing the weight and production materials of the placement table 200, facilitating the opening of the first limiting hole 240 on the placement table 200, and at the same time reducing the assembly steps of the placement table 200.

[0044] As Figure 4 and Figure 5As shown, the outer wall of the storage table 200 protrudes into the installation groove 210 to form a receiving groove 250 on the side of the storage table 200 away from the installation groove 210, and an avoidance groove 340 for avoiding the protrusion is provided on the annular connector 300. When the limiting member 260 is plugged into the storage table 200 and the annular connector 300, the end of the limiting member 260 that leaks out of the second limiting hole 330 is located in the receiving groove 250, so that the limiting member 260 is accommodated by the receiving groove 250, thereby avoiding the end of the limiting member 260 protruding from the outer wall of the storage table 200 and occupying too much space, thereby avoiding the protrusion and the limiting member 260 of the storage table 200 affecting the placement of the tea bar machine against the wall, so as to facilitate the user to place and use it.

[0045] The annular connector 300 in this embodiment may be provided with one or more than one. Preferably, two annular connectors 300 are provided, and the two annular connectors 300 are symmetrically arranged on both sides of the bottom surface of the back plate 100. This reduces the material consumption of the annular connector 300 while ensuring that the annular connector 300 can stably support the back plate 100, so that the force on both sides of the back plate 100 is more uniform and the installation is more stable.

[0046] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
