[0006] In the above tea bar machine, the bottom surface of the annular overflow glue groove is higher than the bottom surfaces of the inner and outer glue grooves, so that the depths of the inner and outer glue grooves are both greater than the depth of the annular overflow glue groove.

[0007] In the above-mentioned tea bar machine, the width of the inner glue groove is greater than the width of the outer glue groove, and the depth of the inner glue groove is greater than the depth of the outer glue groove.

[0008] In the above tea bar machine, the mounting frame is provided with a first annular rib and a second annular rib abutting against the light-transmitting plate, and the second annular rib surrounds the outer circumference of the first annular rib to form an annular glue overflow groove therebetween.

[0014] The beneficial effects of the utility model are:

[0015] A tea bar machine includes a back panel and a display assembly arranged on the back panel, the display assembly includes a mounting frame and a light-transmitting plate bonded to the mounting frame, the mounting frame is provided with an annular glue overflow groove opening toward the light-transmitting plate and a glue-making groove arranged in the annular glue overflow groove, the mounting frame is further provided with an annular convex rib, the annular glue overflow groove surrounds the outer peripheral side of the annular convex rib to form an inner glue discharge groove between the annular glue overflow groove and the annular convex rib. The technical solution has the following technical effects:

[0016] The utility model arranges the glue groove in the annular glue overflow groove, and arranges the inner glue discharge groove located in the inner circle of the annular glue overflow groove on the installation frame, so that when the light-transmitting plate is installed, the glue used for bonding the light-transmitting plate is injected into the glue groove, and then the light-transmitting plate is covered on the installation frame. Because the glue grooves are all located in the annular glue overflow groove, the glue overflowing from the glue groove will directly enter the annular glue overflow groove when the glue is injected or the light-transmitting plate is covered. If there is too much glue in the annular glue overflow groove and overflows, the annular convex rib can block the glue overflowing from the inner circle of the installation frame, so that the glue stays in the inner glue discharge groove, and the glue is prevented from diffusing to the circuit board installed in the central area of ​​the installation frame, so that the display component is more beautiful, and at the same time the circuit board is kept clean and tidy, and the glue is prevented from interfering with the stable operation of the circuit board.

[0017] The mounting frame is also provided with an outer glue groove, which surrounds the outer peripheral side of the annular glue overflow groove. The outer glue groove can accommodate the colloid overflowing from the annular glue overflow groove to the outer peripheral side, so that the colloid stays in the outer glue groove, thereby preventing a large amount of colloid from overflowing from the outer peripheral side of the connection between the light-transmitting plate and the mounting frame and affecting the assembly of subsequent structures, making the outer peripheral side of the mounting frame more tidy and beautiful.

[0018] The bottom surface of the annular overflow glue groove is higher than the bottom surface of the inner and outer glue grooves, so that the depth of the inner and outer glue grooves are greater than the depth of the annular overflow glue groove. Thus, the space of the inner and outer glue grooves is larger, and the two can fully accommodate the colloid overflowing from the annular overflow glue groove, thereby preventing the colloid from overflowing from the inner or outer glue grooves.

[0019] The width of the inner glue groove is greater than the width of the outer glue groove, and the depth of the inner glue groove is greater than the depth of the outer glue groove, that is, the space of the inner glue groove is set to be larger than the space of the outer glue groove. Even if a large amount of colloid overflows from the annular glue overflow groove to the inner circle of the mounting frame, the inner glue groove can completely accommodate the overflowed colloid, ensuring that the overflowed colloid will not flow onto the circuit board and interfere with the stable operation of the circuit board.

[0020] The mounting frame is provided with a first annular rib and a second annular rib that abut against the light-transmitting plate, and the second annular rib surrounds the outer circumference of the first annular rib to form an annular glue overflow groove therebetween. When the light-transmitting plate is mounted on the mounting frame, the surface of the light-transmitting plate abuts against the tops of the first annular rib and the second annular rib, so that the first annular rib and the second annular rib can not only enclose an annular glue overflow groove for accommodating the colloid, but also support the light-transmitting plate, thereby facilitating the installation of the light-transmitting plate.

[0021] The tops of the first annular rib and the second annular rib are respectively provided with a plurality of notches opening upward, and the colloid in the annular overflow glue groove enters the inner glue groove and the outer glue groove through the notches on both sides. When installing the light-transmitting plate, the notches on the first annular rib and the second annular rib can provide a flow channel for the colloid, so that the excess colloid in the annular overflow glue groove can enter the inner glue groove and the outer glue groove through the notches on both sides, reducing the installation resistance of the colloid in the annular overflow glue groove to the light-transmitting plate, making the installation of the light-transmitting plate smoother and more labor-saving.

[0022] The second annular rib includes an overflow glue strip with a notch, the end of the overflow glue strip is connected to a glue blocking portion located at the corner of the annular overflow glue groove, and the glue blocking portion is provided with a groove with an opening facing the annular overflow glue groove. The provision of the glue blocking portion can enhance the strength of the corner of the installation frame, and the groove provided on the glue blocking portion can both accommodate the colloid overflowing from the annular overflow glue groove and prevent the colloid from overflowing onto the outer side wall of the corner of the installation frame, thereby ensuring the neatness of the buckle and other structures at the corner and preventing the colloid from affecting the connection between the buckle and other structures on the installation frame and the base.

[0023] There are multiple glue grooves, and the multiple glue grooves are evenly distributed in the annular glue overflow groove, which can reduce the amount of colloid injected. At the same time, the structure of arranging multiple glue grooves in a single annular glue overflow groove can reduce the difficulty of production and processing.

[0024] A double row of glue grooves are provided in the annular glue overflow groove, and the double row of glue grooves are staggeredly arranged in the annular glue overflow groove, so that the glue overflowing from one row of glue grooves can overflow to the gap between two adjacent glue grooves in the other row, ensuring stable bonding between the light-transmitting plate and the mounting frame, while making the flow of the glue between the glue groove and the annular glue overflow groove smoother.

[0025] A plurality of positioning ribs are provided on the outer circumference of the installation frame, and the positioning ribs include a connecting portion horizontally extending from the outer side wall of the installation frame and a limiting portion perpendicular to the connecting portion, and the limiting portion limits the position of the light-transmitting plate by abutting against the outer circumference of the light-transmitting plate. The positioning ribs can quickly position the light-transmitting plate during installation, without the need for the staff to align the light-transmitting plate with the installation frame, thereby reducing the difficulty of assembly and improving the efficiency of assembly.

[0044] Example:

[0045] A tea bar machine, such as Figures 1 to 5 As shown, it includes a cabinet with a storage table on the top, a back panel 100 fixed on the storage table, and a kettle placed on the storage table. A display component is installed on the top of the back panel 100. The display component includes a base 500, a mounting frame 300 and a light-transmitting plate 400. The base 500 is installed on the back panel 100. The base 500 has a accommodating cavity 510. The mounting frame 300 is arranged in the accommodating cavity 510 of the base 500, and the light-transmitting plate 400 is bonded to the mounting frame 300. An annular glue overflow groove 310 and a glue applying groove 320 are provided on the installation frame 300. The openings of the annular glue overflow groove 310 and the glue applying groove 320 are arranged toward the light-transmitting plate 400, and the glue applying groove 320 is located inside the annular glue overflow groove 310. An annular convex rib 330 is also provided on the installation frame 300. The annular glue overflow groove 310 surrounds the outer peripheral side of the annular convex rib 330 to form an inner glue discharge groove 340 between the annular glue overflow groove 310 and the annular convex rib 330.

[0046] The utility model arranges the glue groove 320 in the annular glue overflow groove 310, and arranges the inner glue discharge groove 340 located in the inner circle of the annular glue overflow groove 310 on the installation frame 300, so that when installing the light-transmitting plate 400, the glue used for bonding the light-transmitting plate 400 is injected into the glue groove 320, and then the light-transmitting plate 400 is covered on the installation frame 300. Because the glue groove 320 is entirely located in the annular glue overflow groove 310, when the glue is injected or the light-transmitting plate 400 is covered, the glue overflowing from the glue groove 320 will directly enter the annular glue overflow groove 310. If there is too much glue in the annular glue overflow groove 310 and it overflows, the annular convex rib 330 can block the glue overflowing toward the inner circle of the installation frame 300, so that the glue stays in the inner glue discharge groove 340, and the glue is prevented from diffusing to the circuit board installed in the central area of ​​the installation frame 300, making the display component more beautiful, while ensuring the cleanliness of the circuit board and preventing the glue from interfering with the stable operation of the circuit board.

[0047] In this embodiment, an external glue discharge groove 350 is further provided on the installation frame 300. The external glue discharge groove 350 surrounds the outer peripheral side of the annular glue overflow groove 310. The external glue discharge groove 350 can accommodate the colloid overflowing from the annular glue overflow groove 310 to the outer peripheral side, so that the colloid stays in the external glue discharge groove 350, thereby preventing a large amount of colloid from overflowing from the outer peripheral side of the connection between the light-transmitting plate 400 and the installation frame 300 and affecting the assembly of subsequent structures, so that the outer peripheral side of the installation frame 300 is neater and more beautiful.

[0048] In this embodiment, if Figure 4 As shown, the bottom surfaces of the inner glue discharge groove 340 and the outer glue discharge groove 350 are both lower than the bottom surface of the annular glue overflow groove 310, so that the depth of the inner glue discharge groove 340 and the depth of the outer glue discharge groove 350 are both greater than the depth of the annular glue overflow groove 310, thereby making the space between the inner glue discharge groove 340 and the outer glue discharge groove 350 larger, and the two can fully accommodate the colloid overflowing from the annular glue overflow groove 310, avoiding the colloid from overflowing from the inner glue discharge groove 340 or the outer glue discharge groove 350. Preferably, the width of the inner glue groove 340 is greater than the width of the outer glue groove 350, and the depth of the inner glue groove 340 is greater than the depth of the outer glue groove 350, that is, the space of the inner glue groove 340 is set to be larger than the space of the outer glue groove 350. Even if a large amount of colloid in the annular glue overflow groove 310 overflows to the inner circle of the mounting frame 300, the inner glue groove 340 can completely accommodate the overflowed colloid, ensuring that the overflowed colloid will not flow onto the circuit board and interfere with the stable operation of the circuit board.

[0049] like Figure 3As shown, a first annular rib 360 and a second annular rib 370 protruding from the surface of the mounting frame 300 are provided on the mounting frame 300, and the second annular rib 370 surrounds the outer peripheral side of the first annular rib 360 to form an annular glue overflow groove 310 therebetween. When the light-transmitting plate 400 is installed on the mounting frame 300, the surface of the light-transmitting plate 400 abuts against the top of the first annular rib 360 and the second annular rib 370, so that the first annular rib 360 and the second annular rib 370 can not only form the annular glue overflow groove 310 for accommodating the colloid, but also support the light-transmitting plate 400, thereby facilitating the installation of the light-transmitting plate 400.

[0050] Preferably, a plurality of notches 380 are respectively provided on the top of the first annular rib 360 and the second annular rib 370, and the notches 380 open upward and horizontally penetrate the first annular rib 360 or the second annular rib 370. The notches 380 on the first annular rib 360 are used to connect the annular overflowing glue groove 310 and the inner glue discharge groove 340, and the notches 380 on the second annular rib 370 are used to connect the annular overflowing glue groove 310 and the outer glue discharge groove 350. When the light-transmitting plate 400 is installed, the first annular rib 360 is provided with a plurality of notches 380, and the notches 380 on the second annular rib 370 are provided with a plurality of notches 380. The notches 380 on the first annular rib 360 and the second annular rib 370 can provide a flow channel for the colloid, so that when the light-transmitting plate 400 is covered on the mounting frame 300, the excess colloid in the annular glue overflow groove 310 can enter the inner glue discharge groove 340 and the outer glue discharge groove 350 through the notches 380 on both sides under the squeezing of the light-transmitting plate 400, thereby reducing the installation resistance of the colloid in the annular glue overflow groove 310 to the light-transmitting plate 400, making the installation of the light-transmitting plate 400 smoother and more labor-saving.

[0051] like Figure 3 As shown, in this embodiment, the second annular rib 370 includes an overflowing glue strip 371 provided on the side of the annular overflowing glue groove 310 and a glue blocking portion 372 provided at the corner of the annular overflowing glue groove 310, the overflowing glue strip 371 extends along a straight line, the notches 380 are all provided on the overflowing glue strip 371, the glue blocking portion 372 is connected to the end of the overflowing glue strip 371, and the thickness of the glue blocking portion 372 is greater than that of the overflowing glue strip 371, and a groove 3721 is provided on the glue blocking portion 372, and the groove 3721 is The opening is toward the light-transmitting plate 400 and the annular glue overflow groove 310. The setting of the glue blocking part 372 can enhance the strength of the corner of the installation frame 300. The groove 3721 set on the glue blocking part 372 can not only accommodate the glue overflowing from the annular glue overflow groove 310, but also prevent the glue from overflowing to the outer wall of the corner of the installation frame 300, thereby ensuring the neatness of the buckles and other structures at the corners and preventing the glue from affecting the connection between the buckles and other structures on the installation frame 300 and the base 500.

[0052] In the present embodiment, a plurality of glue grooves 320 are provided. The glue grooves 320 are circular and surrounded by annular glue ribs 321. The height of the glue ribs 321 is lower than the first annular rib 360 and the second annular rib 370, so that the glue can flow smoothly from the glue groove 320 to the annular glue overflow groove 310. The plurality of glue grooves 320 are evenly spaced and arranged in a single row in the annular glue overflow groove 310, which can reduce the amount of injected glue. At the same time, the structure of arranging a plurality of glue grooves 320 in a single annular glue overflow groove 310 can reduce the difficulty of production and processing. Of course, it is understandable that the glue grooves 320 in this embodiment can also be provided with double rows, and the double rows of glue grooves are staggered in the annular glue overflow groove, so that the glue overflowing from one row of glue grooves can overflow into the gap between two adjacent glue grooves in the other row, ensuring that the light-transmitting plate 400 and the installation frame 300 are stably bonded, while making the flow of the glue between the glue grooves 320 and the annular glue overflow groove 310 smoother.

[0053] like Figure 4 As shown, in the present embodiment, a plurality of positioning ribs 390 are provided on the outer peripheral side of the mounting frame, and the positioning ribs 390 include a connecting portion 391 and a limiting portion 392. The connecting portion 391 extends horizontally from the outer side wall of the mounting frame 300, and the limiting portion 392 is vertically connected to the end of the connecting portion 391 away from the mounting frame 300 and is provided on the top surface of the mounting frame 300. When the light-transmitting plate 400 is installed on the mounting frame 300, the outer peripheral side of the light-transmitting plate 400 abuts against the limiting portion 392 toward the side wall of the mounting frame 300, and can be moved along the positioning ribs 390 to cover the mounting frame 300. The positioning ribs 390 can be used to quickly install and position the light-transmitting plate 400 during installation, without the need for staff to align the light-transmitting plate 400 with the mounting frame 300, thereby reducing the difficulty of assembly and improving assembly efficiency. Of course, it is understandable that in order to reduce the space occupied by the mounting frame 300 in the base 500, such as Figure 5 As shown, the positioning rib 390 in this embodiment can be separated from the installation frame 300 by breaking or cutting after the light-transmitting plate 400 is installed.

[0054] 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.
