Abstract
Description
Technical Field
[0001] This utility model relates to the field of beverage equipment technology, and in particular to a double-door linkage lock assembly and beverage equipment. Background Technology
[0002] In commercial settings where beverage equipment, such as multi-functional coffee machines, is used for beverage preparation and sales, the coffee door and powder refrigerator door are used extremely frequently. Currently, coffee doors and powder refrigerator doors in coffee shops typically use separate lock systems. This means that staff need to use different keys to open these two doors. This traditional lock setup brings many inconveniences in practice. For example, when staff are hurriedly making coffee, they need to search for the corresponding key among multiple keys to open the coffee door or powder refrigerator door, which not only wastes valuable time but also reduces work efficiency. Moreover, staff also need to constantly keep track of the location of multiple keys to avoid losing them, increasing management costs and effort.
[0003] Frequent searching for and using different keys can easily lead to operational errors by staff in a stressful work environment, such as accidentally taking the wrong key or opening the wrong door, which in turn affects the coffee-making process and quality. Furthermore, managing multiple keys can easily become chaotic, potentially resulting in lost or damaged keys, causing unnecessary trouble for the store's normal operations. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a double-door linkage lock assembly and beverage equipment, which can simultaneously open the coffee door and the powder refrigerator door with a single key. This not only simplifies the operation process and improves work efficiency, but also reduces management costs and avoids a series of problems caused by improper key management.
[0005] This utility model is achieved through the following technical solution:

[0008] The second door panel has a second lock groove.
[0009] The first latch includes a first open position and a first locking position;
[0010] The second latch includes a second open position and a second locking position;
[0011] A lock cylinder assembly includes a lock cylinder body and a rotating shaft coaxially and fixedly connected to the lock cylinder body, wherein the first latch is fixed on the rotating shaft;
[0012] An elastic reset element is used to drive the second latch to move from the second open position to the second locked position;
[0013] When the lock cylinder body rotates around the first direction under the drive of the key, the lock cylinder body drives the first latch to move from the first locked position to the first open position through the rotating shaft, thereby pushing the second latch to move from the second locked position to the second open position; at this time, the first lock groove disengages from the first latch, and the second lock groove disengages from the second latch.
[0014] When the lock cylinder body rotates in the second direction under the drive of the key, the lock cylinder body drives the first latch to move from the first open position to the first locked position through the rotating shaft, and the second latch moves from the second open position to the second locked position under the action of the elastic reset member; at this time, the first lock groove engages with the first latch, and the second lock groove engages with the second latch.
[0015] Furthermore, it also includes a column and a fixing seat fixed on the column, the first hook being located on one side of the column, and the second hook being located on the other side of the column and movably disposed on the fixing seat.
[0016] Furthermore, it also includes a first protrusion that is movably inserted into the column. One end of the first protrusion is fixedly connected to the second hook. When the first hook is in the first open position, the other end of the first protrusion abuts against the first hook.
[0017] Furthermore, a first retaining ring is provided on the outer peripheral surface of the first protrusion. When the first hook is in the first locking position, the first retaining ring abuts against the column.
[0018] Furthermore, the column is provided with a first guide hole through which the first protrusion passes, and the first protrusion can reciprocate along the axial direction of the first guide hole.
[0019] Furthermore, it also includes a connecting rod and a second protrusion that is movably inserted into the column. The connecting rod is movably inserted into the fixed base, and one end of the connecting rod is fixedly connected to the second protrusion, and the other end is fixedly connected to the second hook. One end of the elastic reset member abuts against the second protrusion, and the other end abuts against the fixed base.
[0020] Furthermore, a second retaining ring is provided on the outer peripheral surface of the second protrusion. When the first hook is in the first locking position, the second retaining ring abuts against the column.
[0021] Furthermore, the column is provided with a second guide hole through which the second protrusion passes, and the second protrusion can reciprocate along the axial direction of the second guide hole.
[0022] Furthermore, the lock cylinder assembly also includes a lock shell, which is sleeved on the outside of the lock cylinder body and the first latch, and the lock shell has an avoidance hole at the position corresponding to the first latch.
[0023] This application also provides a beverage device, including the double-door linkage assembly as described above.
[0024] Compared with existing technologies, the advantages of this utility model are:

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0032] like Figures 1-5 As shown, a double-door linkage assembly according to an embodiment of the present invention includes a first door panel 290, a second door panel 340, a first latch 710, and a second latch 720. The first door panel 290 has a first locking groove 291 for engaging with the first latch 710, and the second door panel 340 has a second locking groove 341 for engaging with the second latch 720. The first latch 710 includes a first open position and a first locked position, and the second latch 720 includes a second open position and a second locked position. When the first latch 710 is in the first open position, it disengages from the first locking groove 291, and the first door panel 290 can be opened. Conversely, when the first latch 710 is in the first locked position, it engages with the first locking groove 291, and the first door panel 290 cannot be opened. When the second latch 720 is in the second open position, the second latch 720 is disengaged from the second lock groove 341, and the second door panel 340 can be opened. Conversely, when the second latch 720 is in the second locked position, the second latch 720 is engaged with the second lock groove 341, and the second door panel 340 cannot be opened.
[0033] like Figure 2 The double-door linkage assembly further includes a lock cylinder assembly 730 and an elastic reset member 740. The lock cylinder assembly 730 includes a lock cylinder body 731 and a rotating shaft 732 coaxially fixedly connected to the lock cylinder body 731. A first latch 710 is fixed to the rotating shaft 732, and the elastic reset member 740 drives a second latch 720 from a second open position to a second locked position. (Reference) Figure 3When the lock cylinder body 731 rotates around the first direction under the drive of the key 701, the lock cylinder body 731 drives the first latch 710 from the first locked position to the first open position through the rotating shaft 732, thereby pushing the second latch 720 from the second locked position to the second open position; at this time, the first lock groove 291 disengages from the first latch 710, and the second lock groove 341 disengages from the second latch 720.
[0034] refer to Figure 4 When the lock cylinder body 731 rotates in the second direction under the drive of the key 701, the lock cylinder body 731 drives the first latch 710 to move from the first open position to the first locked position via the rotating shaft 732, and the second latch 720 moves from the second open position to the second locked position under the action of the elastic reset member 740. At this time, the first lock groove 291 engages with the first latch 710, and the second lock groove 341 engages with the second latch 720. In this application, the operator only needs to insert one key into the lock cylinder body 731, and can simultaneously control the opening and closing of the first door panel 290 and the second door panel 340 by rotating the key 701. This improvement greatly saves operation time, reduces the confusion caused by the operator frequently searching for and using different keys when busy, makes the operation process simpler and more efficient, and significantly improves work efficiency.
[0035] The lock cylinder assembly 730 also includes a lock housing 733, which is sleeved on the outside of the lock cylinder body 731 and the first latch 710. The lock housing 733 has an clearance hole 734 corresponding to the position of the first latch 710. (See reference...) Figure 3 When the first hook 710 is in the first locking position, the first hook 710 at least partially protrudes through the clearance hole 734 and engages with the first locking groove 291.
[0036] like Figure 5 As shown, the double-door linkage assembly also includes a column 750 and a mounting base 760 fixed on the column 750. A first hook 710 is located on one side of the column 750, and a second hook 720 is located on the other side of the column 750 and is movably mounted on the mounting base 760. The column 750 and the mounting base 760 provide stable support for the second hook 720, ensuring the stability of the double-door linkage assembly structure.
[0037] For example Figure 2As shown, the double-door linkage assembly also includes a first protrusion 770 that is movably inserted into the column 750. One end of the first protrusion 770 is fixedly connected to the second hook 720. When the first hook 710 is in the first open position, the other end of the first protrusion 770 abuts against the first hook 710. When the staff needs to open both doors, they only need to quickly rotate the key 701. The first protrusion 770 quickly drives the second hook 720 to move and disengage from the second lock groove 341, thereby realizing the synchronous and rapid opening of both doors.
[0038] A first retaining ring 771 is abutted on the outer peripheral surface of the first protrusion 770. When the first latch 710 is in the first locking position, the first retaining ring 771 abuts against the column 750. The design of the first retaining ring 771 effectively prevents excessive displacement of the first protrusion 770, ensuring the stability and safety of the double-door linkage assembly.
[0039] The column 750 has a first guide hole 751 through which the first protrusion 770 passes, and the first protrusion 770 can reciprocate along the axial direction of the first guide hole 751. The first guide hole 751 can ensure the precise movement of the first protrusion 770, so that the second hook 720 and the second lock groove 341 always maintain precise engagement during frequent use of the double door.
[0040] The double-door linkage assembly also includes a connecting rod 780 and a second protrusion 790 movably inserted into the column 750. The connecting rod 780 is movably inserted into the fixed base 760, with one end fixedly connected to the second protrusion 790 and the other end fixedly connected to the second hook 720. One end of the elastic reset member 740 abuts against the second protrusion 790, and the other end abuts against the fixed base 760. During the process of the first hook 710 rotating to the first open position, the first hook 710 pushes the first protrusion 770 to move horizontally, and the first protrusion 770 then drives the second hook 720 to move synchronously. The second hook 720 then drives the second protrusion 790 to move synchronously through the connecting rod 780. At this time, the elastic reset member 740 gradually enters a compressed state, storing elastic potential energy. When the first latch 710 is in the first locked position, the elastic reset member 740 releases elastic potential energy, pushing the second protrusion 790 and the second latch 720 to reset. At this time, the second latch 720 is precisely engaged with the second locking groove 341 again, that is, the second latch 720 moves from the second open position to the second locked position.
[0041] refer to Figure 5 To prevent the elastic reset element 740 from falling off, the elastic reset element 740 is sleeved on the connecting rod 780. The elastic reset element 740 can be a spring or other elastic element.
[0042] A second retaining ring 791 is abutted on the outer peripheral surface of the second protrusion 790. When the first latch 710 is in the first locking position, the second retaining ring 791 abuts against the column 750. The design of the second retaining ring 791 effectively prevents excessive displacement of the second protrusion 790, ensuring the stability and safety of the linkage component.
[0043] The column 750 has a second guide hole 752 through which the second protrusion 790 passes, and the second protrusion 790 can reciprocate along the axial direction of the second guide hole 752. The second guide hole 752 ensures the precise movement of the second protrusion 790, further reducing operational errors caused by mechanical errors. At the same time, in conjunction with the synergistic effect of the first guide hole 751 and the first protrusion 770, it ensures that the second hook 720 and the second locking groove 341 always maintain precise engagement during the opening and closing of the double doors, effectively improving the overall operating efficiency of the equipment and the user experience, and reducing the frequency of maintenance.
[0044] On the other hand, this application also provides a beverage device, including the double-door linkage assembly as described above. This beverage device can be a multi-functional beverage device integrating a coffee machine, a refrigerator, and a powder dispenser, in which case the first door panel 290 and the second door panel 340 respectively refer to the coffee door and the powder refrigerator door. Alternatively, this beverage device can be a multi-functional coffee machine that only includes a coffee machine and a refrigerator, in which case the first door panel 290 and the second door panel 340 respectively refer to the coffee door and the refrigerator door.
[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
