[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a tea bar machine, comprising a cabinet and a back panel arranged on the top of the cabinet, a display device is provided on the upper part of the side wall of the back panel, the back of the display device is rotatably connected to the back panel through a rotating shaft, an elastic locking mechanism is provided on one of the display device and the back panel, and a plurality of locking grooves are provided on the other of the two, and the elastic locking mechanism is clamped in different locking grooves to adjust the inclination angle of the display device.

[0005] In the above-mentioned tea bar machine, the elastic locking mechanism includes a mounting seat with a mounting cavity, the mounting seat is provided with a through hole connected to the mounting cavity, and also includes a spring and a marble arranged in the mounting cavity. The marble extends out of the through hole under the push of the spring and is engaged with the locking groove.

[0006] In the above-mentioned tea bar machine, the inner diameter of the through hole is smaller than the ball diameter of the marble, so as to prevent the marble from freely escaping from the mounting cavity through the through hole.

[0007] In the above-mentioned tea bar machine, a limiting convex rib is provided on the inner wall of the installation cavity and is arranged around the through hole, and the outer peripheral side of the marble is against the limiting convex rib.

[0008] In the above tea bar machine, a positioning column coaxial with the through hole is also provided on the inner wall of the installation cavity, and the end of the spring away from the marble is sleeved on the positioning column and abuts against the inner wall of the installation cavity.

[0009] In the above-mentioned tea bar machine, the rotating shaft is passed through the mounting seat, and an elastic member located in the mounting cavity is disposed outside the rotating shaft. The two ends of the elastic member respectively abut against the mounting seat and the rotating shaft to push the plug-in end of the rotating shaft out of the mounting cavity and plug into the display device or the back panel.

[0010] In the above tea bar machine, the two ends of the rotating shaft are respectively the plug-in end and the operating end, the mounting seat is provided with an avoidance hole connected to the mounting cavity, and the part of the operating end extending out of the mounting cavity through the avoidance hole is provided with an operating hole radially penetrating the rotating shaft.

[0012] In the above-mentioned tea bar machine, the back panel includes a plate body and a mounting boss arranged on one side of the plate body. Two elastic locking mechanisms are provided. Both elastic locking mechanisms are installed on the back of the display device and are respectively located on both sides of the mounting boss. The locking groove is arranged on the end face of the mounting boss.

[0013] In the above-mentioned tea bar machine, a rotating shaft hole for inserting the rotating shaft is provided on the end surface of the mounting boss, and a plurality of locking grooves are arranged around the rotating shaft hole.

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

[0015] A tea bar machine includes a cabinet and a back panel arranged on the top of the cabinet, a display device is arranged on the upper part of the side wall of the back panel, the back of the display device is rotatably connected to the back panel via a rotating shaft, an elastic locking mechanism is arranged on one of the display device and the back panel, and a plurality of locking grooves are arranged on the other of the two, and the elastic locking mechanism is clamped in different locking grooves to adjust the tilt angle of the display device. The technical solution has the following technical effects:

[0016] The utility model connects the display device to the back plate by rotation, so that the user can adjust the tilt angle of the display device by rotating the display device. When users of different heights need to view the display device, the users can rotate the display device according to their own height and sight angle to adjust the tilt angle of the display device, so that the display device in the tilted position is at an angle that is easy to view or operate. When a kettle is boiling water on the cabinet of the tea bar machine, the user can rotate the display device to a vertical position (that is, the display panel of the display device is vertically arranged) to avoid the top of the kettle mouth, so that the water vapor sprayed from the kettle mouth can directly escape upward into the air, avoiding the display device from being blocked on the rising path of the water vapor, thereby avoiding the water vapor condensing on the surface of the display device or entering the display device to cause the display device to be damaged by moisture, thereby extending the service life of the display device. By respectively arranging an elastic locking mechanism and a plurality of locking grooves on the display device and the back panel, the elastic locking mechanism can be snapped into the corresponding locking groove when rotated to the angle required by the user to limit the display device. That is, the elastic locking mechanism can maintain the display device at different tilt angles by snapping into different locking grooves to prevent the display device from rotating freely, so that the display device can be stably maintained at the angle required by the user when there is no external force, thereby improving the user experience.

[0017] The elastic locking mechanism includes a mounting seat with a mounting cavity, the mounting seat is provided with a through hole communicating with the mounting cavity, and also includes a spring and a marble arranged in the mounting cavity, the marble extends out of the through hole under the push of the spring and is engaged with the locking groove. By setting the elastic locking mechanism as a structure in which the mounting seat, the spring and the marble cooperate, the spring always keeps pushing the marble at the through hole during the rotation of the display device, and when the display device is rotated to the right position, the marble extends out of the mounting cavity through the through hole and extends into the aligned locking groove under the push of the spring, so as to realize automatic locking of the display device at various angles, and the cooperation of the spring and the marble enables the user to push the marble to automatically disengage from the engaged locking groove and retract into the through hole by simply rotating the display device, so that the rotation of the display device is smoother and the operation is convenient and simple.

[0018] The inner diameter of the through hole is smaller than the ball diameter of the marble, so as to prevent the marble from freely escaping from the mounting cavity through the through hole. The mounting seat can limit the marble in the mounting cavity through the through hole, and when the elastic locking mechanism is not installed on the display device, the marble is prevented from freely escaping from the mounting cavity through the through hole under the push of the spring, thereby ensuring the stability of the installation between the marble and the mounting seat.

[0019] The inner wall of the installation cavity is provided with a limiting convex rib arranged around the through hole, and the outer peripheral side of the marble is against the limiting convex rib. The marble is limited by the limiting convex rib so that the central axis of the through hole passes through the center of the marble, that is, the marble can only approach or move away from the through hole along the central axis of the through hole, preventing the marble from being unable to align with the through hole due to vibration and other reasons, ensuring that the marble can always extend out of or retract into the installation cavity through the through hole, thereby ensuring the stable locking of the marble and the locking groove.

[0020] A positioning column coaxial with the through hole is also provided on the inner wall of the installation cavity, and the end of the spring away from the marble is sleeved on the positioning column and abuts against the inner wall of the installation cavity. The positioning column can not only reduce the difficulty of assembling the spring during assembly and facilitate the rapid installation and positioning of the spring, but also limit the spring to ensure that the spring can always align with and stably push the marble, ensuring the stable operation of the elastic locking mechanism.

[0021] The rotating shaft is passed through the mounting seat, and an elastic member located in the mounting cavity is disposed outside the rotating shaft. The two ends of the elastic member are respectively against the mounting seat and the rotating shaft to push the plug-in end of the rotating shaft out of the mounting cavity and plugged into the display device or the back panel. When the display device is mounted on the back panel, the plug-in end of the rotating shaft extends out of the mounting cavity through the limiting hole for plugging, so that the display device and the back panel are rotatably connected through the rotating shaft. When the user needs to remove the display device from the back panel, the plug-in end extending out of the limiting hole is retracted into the mounting cavity to realize the removal of the display device. The installation and removal are convenient and simple, which improves the user experience and facilitates the user to repair and replace the display device.

[0022] The two ends of the rotating shaft are respectively a plug-in end and an operating end. The mounting seat is provided with an avoidance hole connected to the mounting cavity. The part of the operating end extending out of the mounting cavity through the avoidance hole is provided with an operating hole that radially penetrates the rotating shaft. When the user needs to remove the display device from the back panel, he only needs to pass the rod-shaped tool through the operating hole, and then pull the tool to drive the plug-in end of the rotating shaft to retract into the limiting hole, so that the display device is separated from the back panel. The setting of the operating hole allows the user to increase the contact area between the hand and the operating end by inserting the tool therein, and the operation is more labor-saving.

[0023] The plug-in end is a cylinder, and the operating end includes a stop plate and an operating plate with an operating hole. The operating plate and the stop plate cross to form the operating end, and the avoidance hole cooperates with the operating end. The plug-in end of the cylinder is convenient for plugging with the back plate, and the operating plate and the stop plate cross to form the operating end, which can enhance the strength of the operating end, facilitate the plugging of the shaft, and prevent the shaft from bending and breaking.

[0024] The back plate includes a plate body and a mounting boss disposed on one side of the plate body. Two elastic locking mechanisms are provided. Both elastic locking mechanisms are mounted on the back of the display device and are respectively located on both sides of the mounting boss. The locking groove is disposed on the end surface of the mounting boss. By arranging the display device on the mounting boss on the side of the plate body, it is possible to avoid the vertically disposed side surface of the plate body limiting the rotation angle of the display device. The user can adjust the display device at a large angle so as to adjust it to an angle suitable for the user to view, thereby improving the user's experience.

[0025] 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

The back side of the display device 300 is rotatably connected to the upper part of the side wall of the back panel 200 through a rotating shaft 500, so that the display device 300 can rotate on the back panel 200 around the rotating shaft 500, and an elastic locking mechanism 400 is provided on the back side of the display device 300, and a plurality of locking grooves 221 are provided on the plane where the back panel 200 and the elastic locking mechanism 400 are in contact. When the user rotates the display device 300, the display device 300 rotates around the rotating shaft 500, and the elastic locking mechanism 400 passes through each locking groove 221 in turn. When the user rotates the display device 300 to a suitable angle, the elastic locking mechanism 400 is snapped into the locking groove 221 corresponding to it to limit the display device 300 and prevent the display device 300 from rotating freely. Of course, it is understandable that the elastic locking mechanism 400 and the locking groove 221 in this embodiment may also be exchanged, that is, the elastic locking mechanism 400 is provided on the back plate 200 , and the locking groove 221 is provided on the display device 300 .

[0051] The utility model connects the display device 300 to the back plate 200 by rotation, so that the user can adjust the tilt angle of the display device 300 by rotating the display device 300. When users of different heights need to view the display device 300, the users can rotate the display device 300 according to their own height and sight angle to adjust the tilt angle of the display device 300. Figure 2 As shown, the display device 300 in the inclined position is at an angle that is easy to view or operate. When the kettle is boiling water on the cabinet 100 of the tea bar machine, the user can rotate the display device 300 to a vertical position (that is, the display panel of the display device 300 is vertically arranged), as shown in FIG. Figure 3 As shown, the upper part of the kettle mouth is avoided, so that the water vapor sprayed from the kettle mouth can directly escape upward into the air, avoiding the display device 300 from being blocked on the rising path of the water vapor, thereby preventing the water vapor from condensing on the surface of the display device 300 or entering the display device 300 to cause the display device 300 to be damaged by moisture, thereby extending the service life of the display device 300. By respectively providing an elastic locking mechanism 400 and a plurality of locking grooves 221 on the display device 300 and the back plate 200, the elastic locking mechanism 400 can be inserted into the corresponding locking groove 221 when rotating to the angle required by the user, so as to limit the display device 300, that is, the elastic locking mechanism 400 can be inserted into different locking grooves 221 to maintain the display device 300 at different tilt angles, avoiding the display device 300 from rotating freely, so that the display device 300 can be stably maintained at the angle required by the user when there is no external force, thereby improving the user's use experience.

[0052] like Figure 5 and Figure 6 As shown, the elastic locking mechanism 400 includes a mounting seat 410, a spring 420 and a marble 430. The mounting seat 410 includes a first shell and a second shell. The first shell and the second shell are buckled to form a mounting cavity 411 located inside the mounting seat 410. The first shell and the second shell are locked by screws. A through hole 414 is provided on the mounting seat 410. The through hole 414 is connected to the mounting cavity 411.

By setting the elastic locking mechanism 400 as the mounting seat 410, the spring 420 The structure of the spring 420 and the marble 430 cooperates so that during the rotation of the display device 300, the spring 420 always keeps pushing the marble 430 at the through hole 414. When the display device 300 is rotated into place, the marble 430, pushed by the spring 420, extends out of the installation cavity 411 through the through hole 414 and extends into the aligned locking groove 221, so as to realize automatic locking of the display device 300 at various angles. The cooperation between the spring 420 and the marble 430 allows the user to only rotate the display device 300, and the marble 430 can automatically disengage from the locked locking groove 221 and retract into the through hole 414, so that the rotation of the display device 300 is smoother and the operation is convenient and simple. Preferably, the inner diameter of the through hole 414 is smaller than the ball diameter of the marble 430, so that the mounting seat 410 can limit the marble 430 in the mounting cavity 411 through the through hole 414, and when the elastic locking mechanism 400 is not mounted on the display device 300, the marble 430 is prevented from freely escaping from the mounting cavity 411 through the through hole 414 under the push of the spring 420, thereby ensuring the stability of the installation between the marble 430 and the mounting seat 410. In this embodiment, the mounting cavity 411 may be provided with one group of marbles 430 and springs 420, or may be provided with multiple groups (two or more groups) of marbles 430 and springs 420, and the multiple groups of marbles 430 and springs 420 are arranged around the central axis of the mounting seat 410.

The outer peripheral side of the marble 430 abuts against the inner wall of the limiting rib 412, so that the marble 430 is limited by the limiting rib 412, so that the central axis of the through hole 414 passes through the center of the marble 430, that is, the marble 430 can only approach or move away from the through hole 414 along the central axis of the through hole 414, preventing the marble 430 from being unable to align with the through hole 414 due to vibration and other reasons, ensuring that the marble 430 can always extend or retract into the installation cavity 411 through the through hole 414, thereby ensuring the stable locking of the marble 430 and the locking groove 221. Figure 6As shown, in this embodiment, a positioning column 413 is also provided on the inner wall of the installation cavity 411. The positioning column 413 and the through hole 414 are respectively provided on two opposite inner walls of the installation cavity 411, and the positioning column 413 and the through hole 414 are coaxially provided. One end of the spring 420 is sleeved on the positioning column 413 and abuts against the inner wall of the installation cavity 411, and the other end abuts against the marble 430 to push the marble 430 toward the through hole 414. The positioning column 413 can not only reduce the difficulty of assembling the spring 420 during assembly, and facilitate the rapid installation and positioning of the spring 420, but also limit the spring 420 to ensure that the spring 420 can always align with and stably push the marble 430, thereby ensuring the stable operation of the elastic locking mechanism 400.

[0054] like Figure 6 As shown, in this embodiment, a limiting hole 415 communicating with the mounting cavity 411 is provided on the mounting seat 410, and the limiting hole 415 and the through hole 414 are located on the same end surface of the mounting seat 410.

The plug-in end 510 is inserted into the limiting hole 415 and can extend out of or retract into the mounting cavity 411 through the limiting hole 415. An elastic member 440 is provided in the mounting cavity 411. The elastic member 440 is sleeved on the outer side of the rotating shaft 500. One end of the elastic member 440 abuts against the inner wall of the mounting cavity 411, and the other end of the elastic member 440 abuts against the rotating shaft 500, so as to push the rotating shaft 500 out of the mounting cavity 411 in the direction of the limiting hole 415. 11. When the display device 300 is installed on the back panel 200, the plug-in end 510 of the rotating shaft 500 extends out of the installation cavity 411 through the limiting hole 415 under the push of the elastic member 440, and is plugged into the back panel 200, so that the display device 300 and the back panel 200 are rotatably connected through the rotating shaft 500. When the user needs to remove the display device 300 from the back panel 200, it is only necessary to retract the plug-in end 510 extending out of the limiting hole 415 into the installation cavity 411 to disengage the rotating shaft 500 from the back panel 200, thereby realizing the disassembly of the display device 300. The installation and disassembly of the display device are convenient and simple, thereby improving the user experience and facilitating the user to repair and replace the display device 300. A avoidance hole 416 connected to the mounting cavity 411 is also provided on the mounting seat 410. The operating end 520 of the rotating shaft 500 extends out of the mounting cavity 411 through the avoidance hole 416. An operating hole 523 is provided at the portion of the operating end 520 extending out of the mounting cavity 411. The operating hole 523 is arranged to penetrate the rotating shaft 500 along the radial direction of the rotating shaft 500. When the user needs to remove the display device 300 from the back plate 200, the user only needs to pass the rod-shaped tool through the operating hole 523, and then pull the tool to drive the plug-in end 510 of the rotating shaft 500 to retract completely into the limiting hole 415 to separate the rotating shaft 500 from the back plate 200. The setting of the operating hole 523 allows the user to increase the contact area between the hand and the operating end 520 by inserting the tool therein, making the operation more labor-saving.

[0055] like Fig.10 As shown, the plug-in end 510 of the rotating shaft 500 is a cylinder, and the plug-in end 510 of the cylinder facilitates the plugging of the rotating shaft 500 with the back plate 200. The operating end 520 includes a stop plate 521 and an operating plate 522. The operating plate 522 and the stop plate 521 cross to form the operating end 520, thereby enhancing the strength of the operating end 520.
