[0045] Reference Figure 1-13 , which is a plug fixing structure of a tea bar machine disclosed in the utility model, and is used for a tea bar machine, including: a tea bar machine composed of a backrest 1, a table top 2 and a body 3, an inner first assembly 4 installed below the cavity of the table top 2, and a second assembly 5 installed above the cavity of the backrest 1. A positioning groove 6 is provided above the table top 2, and a male terminal head 7 is clamped inside the positioning groove 6. A female terminal head 8 passing through the bottom of the backrest 1 is installed in the cavity of the second assembly 5; the male terminal head 7 and the female terminal head 8 in this application both use the locking harness terminal of the prior art. Compared with the method of connecting using a USB interface in the prior art, the manufacturing method in this application is simpler, and the use of USB is eliminated. In the process of connecting the table top and the backrest control panel, the existing conventional manually connected locking harness terminal is directly used, so no additional special parts are required. This design simplifies the manufacturing process of the tea bar machine, reduces costs, and improves manufacturing efficiency.

[0046] When the backrest 1 and the table top 2 are assembled, the male terminal head 7 and the female terminal head 8 in the second assembly 5 are plugged into each other;

[0047] The first assembly 4 and the second assembly 5 both integrate water inlet and water outlet functions.

[0048] The male terminal head 7 can maintain a stable position when inserted into the female terminal head 8, avoiding poor connection or disconnection due to looseness or instability. By effectively fixing the male terminal head 7 and the female terminal head 8, the risk of damage or failure caused by accidental impact or incorrect insertion is successfully reduced.

[0049] Embodiment 1:

[0050] In this embodiment, the first assembly 4 includes a mounting plate 9, and two positioning cylinders 10 facing two width direction edges are fixedly connected to the top of the mounting plate 9. A groove 11 adapted to the positioning cylinder 10 and located on both sides of the positioning groove 6 passes through the top of the table 2, and the top of the mounting plate 9 abuts against the bottom of the male terminal head 7.

[0051] The opposite side of the mounting plate 9 is provided with a mounting groove 12, and one side of the mounting plate 9 is provided with a first wiring groove 13 connected to the mounting groove 12. The first wiring groove 13 and the second wiring groove 16 facilitate the wiring of the female terminal head 8 and the male terminal head 7, respectively. When the wiring harness is too long, there is no need to insert it from the end, which facilitates the subsequent installation of the female terminal head 8 and the male terminal head 7, and makes the installation and connection of the wiring harness more orderly and simple. It helps to reduce the confusion and crossing of the wiring harness, and reduces the risk of damage to the wiring harness.

[0052] In this embodiment, the second assembly 5 includes a combination plate 14, an extension tube 15 fixedly connected to the combination plate 14 above, a second wiring groove 16 penetrating through one side of the extension tube 15 is opened on one side of the combination plate 14, and the female terminal head 8 is installed inside the extension tube 15;

[0053] A positioning mechanism for fixing the position of the female terminal head 8 is inserted into the extension tube 15; the positioning mechanism is designed to further ensure that the female terminal head 8 can be correctly positioned and locked during the insertion process, preventing the subsequent random movement of the female terminal head 8, thereby ensuring the stability and reliability of the female terminal head 8.

[0054] A plurality of positioning blocks 17 are fixedly connected to the lower portion of the combined plate 14 . A slot 18 is formed through the central portion of the lower portion of the backrest 1 , and the female terminal head 8 passes through the slot 18 .

[0055] In this embodiment, a sealing cylinder 19 plugged into the positioning cylinder 10 is fixedly connected to the side of the combination plate 14 facing the mounting plate 9, and a circular hole 20 matching the sealing cylinder 19 and located on both sides of the slot 18 is penetrated below the backrest 1, and the sealing cylinder 19 is provided with a plurality of annular grooves from top to bottom, and a sealing ring 21 is fitted inside the annular groove. The tight connection between the male terminal head 7 and the female terminal head 8 is ensured by the cooperation between the sealing cylinder 19 and the positioning cylinder 10, and the guiding effect of the positioning cylinder 10 ensures that the male terminal head 7 can be accurately inserted into the female terminal head 8, thereby ensuring the stability and correctness of the connection.

[0056] The fitting design of the sealing ring 21 and the annular groove ensures the complete sealing effect of the sealing cylinder 19. The sealing ring 21 is made of soft rubber or silicone, and the sealing ring 21 fits tightly on the inner wall of the positioning cylinder 10, ensuring the maximization of the sealing performance.

[0057] In this embodiment, a water outlet pipe 22 connected to the sealing cylinder 19 is connected above the combined plate 14 , a water inlet pipe 23 is connected below the positioning cylinder 10 , and the water inlet pipe 23 is connected to the water outlet pipe 22 .

[0058] The design of the water inlet pipe 23 and the water outlet pipe 22 can realize the water delivery function of the tea bar machine without interfering with the connection between the male terminal head 7 and the female terminal head 8. Such a design effectively prevents subsequent liquid from flowing out of the interface, thereby avoiding the possibility of liquid damaging the male terminal head 7 and the female terminal head 8.

[0059] In this embodiment, the male terminal head 7 includes a first shell 24, and the left and right sides of the first shell 24 are elastically matched with buckles 25. After the buckles 25 are unfolded, a plurality of fixed slots 26 are opened on the side facing the table 2. One side of the male terminal head 7 is fixedly connected to a positioning protrusion 27 with a slope on the top, and the front and rear sides of the first shell 24 are fixedly connected to positioning plates 28 that fit at the edge of the positioning slot 6. The design of the fixed slot 26 can fix the position of the buckle 25, avoid the subsequent male terminal head 7 from falling from the positioning slot 6, and improve the stability of the male terminal head 7 after installation;

[0060] Among them, the buckle 25 will shrink after entering the positioning groove 6, and rebound into a triangular structure after the male terminal head 7 enters the positioning groove 6, so that the buckle 25 and the upper edge of the positioning groove 6 are abutted. In this embodiment, the female terminal head 8 includes a second shell 29 with a T-shaped structure, and the first side of the second shell 29 is fixedly connected to a baffle 30 that fits at the edge of the extension tube 15; further, the baffle 30 is provided to prevent the buckle from sliding out of the extension tube 15, and the inner side of the baffle 30 fits at the edge of the extension tube 15. A straight groove 31 is provided on the second side of the second shell 29, and a plate 32 located inside the straight groove 31 is movably connected to the second side of the second shell 29;

[0061] A snap-fitting protrusion 33 that matches the positioning protrusion 27 is disposed on one side of the plate body 32 , and through slots 34 for the buckle 25 to move are provided on both left and right sides of the second housing 29 .

[0062] Specifically, the male terminal head 7 and the female terminal head 8 in the present application are both prior art.

[0063] In this embodiment, the positioning mechanism includes a connecting plate 35, and the connecting plate 35 is fixedly connected to two L-shaped guide plates 36 on one side of the extension tube 15, and the guide plates 36 and the step portion of the second housing 29 are mutually abutted, and the female terminal head 8 is located in the space between the two guide plates 36; an inclined plate 37 for pushing the plate body 32 to unfold is provided between the two guide plates 36. The connecting plate 35 is fixed to one side of the extension tube 15 by bolts. Specifically, two threaded tubes are fixedly connected to one side of the extension tube 15, and through holes corresponding to the threaded tubes are penetrated and opened on the opposite side of the connecting plate 35.

[0064] The guide plate 36 plays the role of filling the space. This arrangement can prevent the male terminal head 7 from sliding after the insertion, further ensuring that the male terminal head 7 can be accurately positioned and locked when inserted, thereby enhancing the stability of the connection.

[0065] The inclined plate 37 can be arranged to keep the plate body 32 in an unfolded state, thereby preventing the plate body 32 from being unable to be disassembled due to the combination between the snap-fit ​​protrusion 33 of the plate body 32 and the positioning protrusion 27 of the interface. The effect of quick disassembly and assembly is achieved without changing the original structure.

[0066] Example 2

[0067] The first assembly 4 includes a mounting plate 9, on which a combination tube 39 is mounted. The combination tube 39 can pass through the positioning groove 6, and then the male terminal head 7 is fixed on the top of the combination tube 39 by the buckle 25 to achieve position fixation. The positioning plates 28 on both sides of the male terminal abut against the steps of the combination tube 39.

[0068] The second assembly 5 includes a combination plate 14, and the upper cross-section of the combination plate 14 is a bonding plate 40 with a "concave" shape. A bonding block 41 is installed on one side of the mounting plate 9. The bonding block 41 is provided with a slope on the side facing the female terminal head 8 to push the plate body 32 to move. The female terminal head 8 is installed between the space between the bonding plate 40 and the bonding block 41 and passes through the combination plate 14.

[0069] The above embodiments may be combined with each other, and even the male terminal plate body 32 may be cut off and the related structures may be simplified.

[0070] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the shape and principle of the utility model should be included in the protection scope of the utility model.
