[0004] However, the door shelf inside the refrigeration equipment is fixed to the door, and its position relative to the door cannot be adjusted, so it cannot support items of various shapes and is inconvenient to use. Utility Model Content

[0005] The purpose of this application is to provide a refrigeration device that can adjust the height of the door shelf relative to the door body, thereby facilitating the support of items of various shapes.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] According to one aspect of this application, a refrigeration device is provided, comprising: a door body, a door shelf, and a locking assembly; the door body extends vertically, and a guide post extending vertically is provided on the door body, the guide post having a plurality of vertically arranged engaging slots; the door shelf is movably disposed on the guide post, and a working space is provided within the door shelf; the locking assembly is housed within the working space, the locking assembly comprising: a locking rod, a pressing member, and a transmission structure; the locking rod is disposed on a side wall of the door shelf facing the engaging slots, the door shelf being movable horizontally to slide into and engage within the engaging slots; the pressing member is movably disposed on the side wall of the door shelf; the transmission structure is rotatably connected within the working space, the transmission structure drivingly connecting the pressing member and the locking rod, and when the pressing member is pressed, the transmission structure is used to convert the pressing movement of the pressing member into the horizontal movement of the locking rod.

[0008] The above technical solution has the following advantages or beneficial effects:

[0009] When a user needs to use the door shelf to accommodate objects of different shapes, the user presses the pressing component. The transmission structure converts the pressing movement of the component into the horizontal movement of the locking lever, controlling the locking lever to slide into and out of the engagement slot, thereby quickly adjusting the height of the door shelf relative to the door. Furthermore, the locking assembly of this refrigeration device is ergonomically designed, allowing the user to lock the lever into the engagement slot simply by pressing with their fingers while holding the door shelf, enhancing user convenience and improving the user experience.

[0010] In some embodiments, the pressing member is vertically inserted into the side wall of the door shelf; the transmission structure includes a rotating member that extends vertically and is rotatably connected to the inner wall of the workspace, the rotating member drivingly connecting the pressing member and the locking rod respectively, for converting the vertical movement of the pressing member into the horizontal movement of the locking rod.

[0011] The above technical solution has the following advantages or beneficial effects:

[0012] The pressing element extends vertically. When the user holds the door shelf and needs to move it, they simply bend their fingers to press the pressing element. This, along with the rotating component, converts the vertical movement of the pressing element into the horizontal movement of the locking lever, allowing the locking lever to quickly move out of the engagement slot, thus improving operational efficiency. Furthermore, the vertical pressing method of this element allows for different finger pressing techniques, facilitating application of force with the thumb, index finger, or little finger.

[0013] In some embodiments, the pressing member has a first sliding groove that extends horizontally; the rotating member has a first moving part that is movably accommodated within the first sliding groove.

[0014] The above technical solution has the following advantages or beneficial effects:

[0015] The transmission structure used for the transmission connection between the pressing element and the rotating element is simplified, so that the vertical movement of the pressing element and the rotation of the rotating element can be directly converted, thereby facilitating the installation, disassembly and maintenance of the locking assembly and improving the reliability of the locking assembly.

[0016] In some embodiments, the transmission structure further includes a connecting rod, the two ends of which are rotatably connected to the locking rod and the rotating member, respectively, and the rotation axis of the connecting rod is parallel to the rotation axis of the rotating member.

[0017] The above technical solution has the following advantages or beneficial effects:

[0019] In some embodiments, a second sliding groove is provided on the locking rod, the second sliding groove extends along the moving direction of the pressing member, and a second moving part is provided on the rotating member, the second moving part being movably accommodated in the second sliding groove.

[0020] The above technical solution has the following advantages or beneficial effects:

[0021] An alternative transmission structure connection method is provided, which facilitates the conversion of the rotational motion of the rotating component into the horizontal movement of the locking lever. Furthermore, compared to the linkage transmission method, this structure is simpler, easier to install, disassemble, and maintain, improves the reliability and stability of the locking assembly, and reduces production costs.

[0022] In some embodiments, the locking assembly further includes an elastic element, the two ends of which are respectively connected to the inner wall of the working space and the rotating element, so as to keep the locking rod engaged in the engaging groove.

[0023] The above technical solution has the following advantages or beneficial effects:

[0024] The elastic element absorbs the rotational kinetic energy of the rotating component. After the door shelf is adjusted to the desired height, the elastic element applies an elastic force to the rotating component, causing the locking rod to extend into and engage in the locking groove, thereby confining the door shelf to the door body. The elastic element improves the ease of use and efficiency of the locking assembly.

[0025] In some embodiments, the rotating member is triangular in shape, and includes a first corner, a second corner, and a third corner. The rotation axis of the rotating member is located at the first corner, the second corner is throttle-connected to the pressing member, and the third corner is throttle-connected to the locking rod.

[0026] The above technical solution has the following advantages or beneficial effects:

[0027] A rotating component structure is provided, which can stably and efficiently convert the movement of the pressing component into the horizontal movement of the locking lever, improving the force transmission efficiency and facilitating user pressing. Furthermore, the triangular shape of the rotating component enhances its structural strength and stability, preventing fatigue fracture.

[0028] In some embodiments, the locking assembly further includes a protective box located within the workspace, wherein the locking lever, the pressing member, and the transmission structure are all housed within the protective box.

[0029] The above technical solution has the following advantages or beneficial effects:

[0030] The protective box serves two purposes: firstly, it facilitates the installation and disassembly of the locking lever, pressing component, and transmission structure, thereby improving production efficiency; secondly, it protects the locking lever, pressing component, and transmission structure, enhancing the reliability and stability of the locking assembly.

[0031] In some embodiments, the door shelf has a pressing hole relative to the pressing member; the door shelf has a locking hole relative to the locking rod; the protective box has a pressing channel relative to the pressing hole, the pressing member is slidably accommodated in the pressing channel and passes through the pressing hole to exit the door shelf; the protective box has a locking channel relative to the locking hole, the locking rod is slidably accommodated in the locking channel and passes through the locking hole to exit the door shelf.

[0032] The above technical solution has the following advantages or beneficial effects:

[0033] The pressing holes and pressing channels ensure the stable and reliable movement of the pressing parts, while the locking holes and locking channels ensure the stable and reliable movement of the locking rod, thereby improving the stability and reliability of the locking components.

[0034] In some embodiments, the door body is provided with two guide posts, which are arranged laterally at intervals; a limiting gap is formed between the guide posts and the door body, and a portion of the door shelf is accommodated within the limiting gap to limit the horizontal movement of the door shelf; at least one end of the door shelf is provided with the working space, the locking rod extends longitudinally, and the pressing member passes through the upper side wall of the door shelf.

[0035] The above technical solution has the following advantages or beneficial effects:

[0050] Figure 1 This is a structural schematic diagram of the refrigeration equipment of this utility model.

[0051] See Figure 1 The refrigeration equipment may include a housing 100 and a door 210. The housing 100 has a refrigeration compartment for storing and refrigerating items. The door 210 is closable over the housing 100 to allow the refrigeration compartment to be opened and closed.

[0052] The refrigeration equipment may also include a door shelf 300. The door shelf 300 is located on the side of the door 210 facing the refrigeration compartment, and items can be placed on the door shelf 300. When the door 210 is closed on the cabinet 100, the door shelf 300 and the items on it extend into the refrigeration compartment to refrigerate the items on the door shelf 300, thereby improving the space utilization of the refrigeration equipment.

Figure 7 yes Figure 6 The diagram shows the structure after the cover plate has been removed.

[0056] See Figures 1 to 7 This application provides a refrigeration device, which may include a door body 210, a door shelf 300, and a locking assembly 400. The door body 210 extends vertically and is provided with a vertically extending guide post 230, which has a plurality of vertically arranged engaging slots 231. The door shelf 300 is movably mounted on the guide post 230 and has a working space 331. The locking assembly 400 is housed within the working space 331. The locking assembly 400 may include a locking rod 420, a pressing member 440, and a transmission structure 430. The locking rod 420 is movably mounted horizontally through a side wall of the door shelf 300 facing the engaging slots 231, and the locking rod 420 can slide into and engage within the engaging slots 231. The pressing member 440 is movably mounted through a side wall of the door shelf 300. The transmission structure 430 is a transmission connection between the pressing member 440 and the locking lever 420, for converting the pressing movement of the pressing member 440 into the horizontal movement of the locking lever 420.

[0057] When a user uses the refrigeration equipment to store items of different shapes, they open the door 210. The user holds the door shelf 300 and presses the pressing member 440. The transmission structure 430 converts the pressing movement of the pressing member 440 into the horizontal movement of the locking lever 420, controlling the locking lever 420 to slide out of the engagement groove 231. This allows the door shelf 300 to move rapidly vertically along the guide post 230, adjusting the height of the door shelf 300 relative to the door 210. This allows door shelves 300 of different heights to accommodate objects of different shapes, improving the space utilization of the refrigeration equipment. Furthermore, the locking component 400 of this refrigeration equipment is ergonomically designed, allowing the locking lever 420 to engage with the engagement groove 231 simply by pressing with a finger while the user holds the door shelf 300, simplifying the operation, facilitating user use, and improving the user experience.

[0058] See Figures 1 to 5 In this embodiment, the door 210 is rotatably connected to the cabinet 100. The door 210 can rotate toward the refrigeration compartment to close onto the cabinet 100, thereby sealing the refrigeration compartment and storing items. The door 210 can also rotate away from the refrigeration compartment to open the refrigeration compartment of the cabinet 100, allowing items to be retrieved or placed.

[0059] See Figures 2 to 5In this embodiment, a guide post 230 may be provided on the door body 210. The guide post 230 may be located on the side of the door body 210 facing the refrigeration room. The guide post 230 extends vertically to guide the vertical movement of the door shelf 300 and limit the horizontal movement of the door shelf 300. Multiple engaging slots 231 may be formed on the guide post 230 along the vertical direction to engage with the locking rod 420, thereby limiting the door shelf 300 to different heights of the guide post 230 and realizing the height adjustment of the door shelf 300.

[0060] Furthermore, when the user needs to clean the door shelf 300, they can press the pressing part 440 to disengage the locking rod 420 from the engaging groove 231, and then move the door shelf 300 along the guide post 230 to separate the door shelf 300 from the door body 210, thereby achieving quick disassembly of the door shelf 300 and facilitating the cleaning and replacement of the door shelf 300.

[0061] In some embodiments, a connecting plate 220 is provided on the side wall of the door 210 facing the refrigeration room. The side of the connecting plate 220 away from the door 210 is connected to the guide post 230 to limit the guide post 230 to the door 210.

[0062] In other embodiments, the guide post 230, the connecting plate 220, and the door body 210 are integrally formed, thereby improving the connection strength between the door body 210 and the guide post 230.

[0063] In some embodiments, in the longitudinal direction, a locking groove 231 is formed on the side of the guide post 230 facing the cooling compartment to facilitate adaptation to the locking assembly 400.

[0064] See Figures 2 to 5 In this embodiment, two guide posts 230 may be provided on the door body 210, and the two guide posts 230 are arranged at a distance along the lateral direction. A limiting gap is formed between the guide posts 230 and the door body 210. Part of the door shelf 300 is accommodated within the limiting gap to limit the horizontal movement of the door shelf 300, thereby ensuring the stability and reliability of the door shelf 300 when adjusting its height position and preventing the door shelf 300 from tilting or falling.

[0065] In some embodiments, the two connecting plates 220 are respectively connected to the opposite sides of the two guide posts 230 in the lateral direction, and the two limiting gaps are located on the opposite side of the two guide posts 230. In the projection plane perpendicular to the longitudinal direction, the projection of the door shelf 300 is located between the projections of the two guide posts 230, so that the door shelf 300 can be limited between the two guide posts 230, thereby limiting the movement of the door shelf 300 in the horizontal direction.

[0066] In some embodiments, each of the two guide posts 230 may be provided with a plurality of engaging slots 231, which are arranged opposite to each other. The engaging slots 231 on the two guide posts 230 can engage with the locking component 400 to ensure the stability and reliability of the vertical movement of the door shelf 300 at both ends in the lateral direction.

[0067] See Figures 2 to 5 In this embodiment, a stop block 250 may also be provided on the door body 210. The stop block 250 is located within the limiting interval 240 and extends longitudinally to connect the door body 210 and the guide post 230. The stop block 250 is located below the door shelf 300 to support and stop the door shelf 300 from moving downward, thereby preventing the door shelf 300 from continuing to move downward and dislodging from the guide post 230, and preventing the door shelf 300 from falling to the ground.

[0068] In some embodiments, the stop block 250 is integrally formed with the door body 210, the connecting plate 220 and the guide post 230.

[0069] Figure 8 This is a schematic diagram of the door shelf of this utility model after the cover plate has been removed.

[0070] See Figures 2 to 4 , Figures 6 to 8 In this embodiment, the refrigeration equipment may include a door shelf 300. The door shelf 300 may include a shelf body 310 and a limiting protrusion 320. The shelf body 310 may extend laterally. A storage groove 311 may be formed on the upper surface of the shelf body 310 for placing items. The limiting protrusion 320 may protrude from the lateral sidewall of the shelf body 310, and the limiting protrusion 320 is disposed relative to a limiting gap. The limiting protrusion 320 can engage within the limiting gap to limit the horizontal movement of the shelf body 310.

[0071] In some embodiments, limiting protrusions 320 may be provided on both sides of the shelf body 310. The two limiting protrusions 320 can be engaged in the two limiting gaps respectively to improve the connection strength between the door shelf 300 and the door body 210, and improve the reliability and safety of the refrigeration equipment.

[0072] In other embodiments, the limiting protrusion 320 is integrally formed with the shelf body 310, thereby ensuring the structural strength of the door shelf 300.

[0073] See Figures 2 to 4 , Figures 6 to 8 In this embodiment, the door shelf 300 may also include a cover plate 340.

[0074] A retaining plate 330 may also be protruding from the transverse sidewall of the shelf body 310. The retaining plate 330 extends laterally. The retaining plate 330 can be wrapped around the transverse sidewall of the shelf body 310. A cover plate 340 is detachably fitted onto the retaining plate 330 so that the transverse sidewall of the shelf body 310, the retaining plate 330 and the cover plate 340 can be closed to form a working space 331, which is used to accommodate the locking assembly 400.

[0075] Users can quickly install and repair the locking component 400 by opening the cover 340, thereby improving the installation and maintenance efficiency of the locking component 400.

[0076] In some embodiments, the enclosure panel 330 may be adapted to the outer contour of the transverse sidewall of the shelf body 310 and be easy for the user to grip. In other embodiments, the enclosure panel 330 may be enclosed to form a rectangular structure.

[0077] See Figures 2 to 4 , Figures 6 to 8 In this embodiment, the limiting protrusion 320 can be arranged longitudinally at intervals with the enclosure plate 330. The limiting protrusion and an adjacent enclosure plate 330 can respectively abut against and limit the longitudinal side walls of the guide column 230, thereby ensuring the tight connection between the door shelf 300 and the guide column 230, preventing the door shelf 300 from loosening or falling off, and ensuring the reliability and stability of the refrigeration equipment.

[0078] In some embodiments, the enclosure panel 330 can be integrally formed with the shelf body 310, thereby improving the structural strength and load-bearing capacity of the door shelf 300.

[0079] See Figures 2 to 4 , Figures 6 to 8 In this embodiment, the door shelf 300 may have a pressing hole 332 relative to the pressing member 440, the pressing hole 332 being used to accommodate the pressing member 440. The door shelf 300 may also have a locking hole 333 relative to the locking rod 420, the locking hole 333 being used to accommodate the locking rod 420.

[0080] In some embodiments, the pressing hole 332 may be provided on the upper end wall of the enclosure plate 330 to facilitate pressing by the user. The locking hole 333 may be provided on the longitudinal side wall of the enclosure plate 330 facing the guide post 230 to facilitate the locking rod 420 to extend into and engage in the locking groove 231.

[0081] See Figures 2 to 4 , Figures 6 to 8 In this embodiment, at least one side of the door shelf 300 is provided with an enclosure plate 330 so that at least one side of the door shelf 300 is provided with a working space 331.

[0082] In some embodiments, both transverse side walls of the shelf body 310 may be provided with enclosure plates 330 so that both transverse sides of the shelf body 310 can accommodate locking components 400. The shelf body 310 can be engaged with two guide posts 230 through the two locking components 400 to improve the connection strength, stability and reliability between the door shelf 300 and the door body 210.

[0083] Figure 9 This is a structural schematic diagram of the locking component of this utility model. Figure 10 yes Figure 7 A structural schematic diagram of the mechanism shown from another perspective.

[0084] See Figures 2 to 10 In this embodiment, the refrigeration equipment may include a locking component 400, which is located within the working space 331. A portion of the locking component 400 can extend through the door shelf 300 and is locked in place by a locking groove 231 on the guide post 230. The user can use the locking component 400 to lock the door shelf 300 onto the guide post 230, thereby adjusting the height of the door shelf 300 relative to the door body 210. This allows the door shelf 300 to support items of different shapes, improving the space utilization of the refrigeration equipment.

[0085] The locking assembly 400 may include a locking lever 420, a pressing member 440, and a transmission structure 430. The locking lever 420 extends horizontally and is movably inserted through the enclosure plate 330 to be able to insert into or remove from the engagement slot 231 of the guide post 230. The pressing member 440 is movably inserted through the enclosure plate 330 for user pressing. The transmission structure 430 drives the locking lever 420 and the pressing member 440 to convert the pressing movement of the pressing member 440 into horizontal movement of the locking lever 420, thereby improving the height adjustment efficiency of the door shelf 300, facilitating user operation, and the locking assembly 400 is also ergonomic, facilitating finger pressing and improving the user experience.

[0086] See Figures 6 to 10 In this embodiment, the locking rod 420 can extend longitudinally. One end of the locking rod 420 is located in the working space 331 to be connected to the transmission structure 430, and the other end of the locking rod 420 can pass through the locking hole 333 and engage in the engaging groove 231.

[0087] The pressing member 440 can extend vertically. One end of the pressing member 440 is located within the working space 331 and is connected to the transmission structure 430, while the other end of the pressing member 440 passes through the side wall of the door shelf 300. The pressing member 440 can move vertically and can be converted into longitudinal movement of the locking rod 420 through the transmission structure 430, so that the locking rod 420 extends into and exits the engagement groove 231, thereby enabling the height position adjustment of the door shelf 300 relative to the guide post 230.

[0088] The pressing element 440 extends vertically through the door shelf 300 to accommodate the user's fingers. The user's fingers can press the pressing element 440 to move the locking lever 420 out of the engagement groove 231, thereby improving the convenience and comfort of adjusting the height of the door shelf 300.

[0089] In other embodiments, both the upper and lower ends of the pressing member 440 can pass through the door shelf 300 to enable vertical movement of the pressing member 400.

[0090] See Figure 2 , Figures 4 to 10 In this embodiment, the pressing member 440 extends through the upper end of the door shelf 300 to accommodate the user's thumb or index finger.

[0091] In some embodiments, the pressing member 440 extends through the lower end of the door shelf 300 to accommodate the user's little finger. When the pressing member 440 extends through the lower end of the door shelf 300, the pressing member 440 can also move downward under its own weight, thereby driving the locking rod 420 to extend into the engaging groove 231 through the transmission structure 430.

[0092] See Figure 7 , Figure 9 and Figure 10 In this embodiment, the pressing member 440 may be provided with a first sliding groove 441, which extends in the horizontal direction and is used for transmission connection with the transmission structure 430.

[0093] In some embodiments, the first groove 441 may extend along the moving direction of the locking lever 420.

[0094] See Figure 7 , Figure 9 and Figure 10 In this embodiment, the transmission structure 430 may include a rotating member 431, which extends vertically. The rotating member 431 is rotatably connected to the inner wall of the working space 331. The rotation axis 4312 of the rotating member 431 extends horizontally. The rotating member 431 is connected to the pressing member 440 and the locking lever 420 respectively to convert the vertical movement of the pressing member 440 into the horizontal movement of the locking lever 420.

[0095] A first movable part 4314 may be protruded from the rotating member 431, and the first movable part 4314 is movably accommodated within the first sliding groove 441. When the user presses the pressing member 440, the pressing member 440 moves vertically, and the inner wall of the first sliding groove 441 abuts against the first movable part 4314, thereby causing the first movable part 4314 to slide within the first sliding groove 441. The first movable part 4314 causes the rotating member 431 to rotate around the rotation axis 4312 of the rotating member 431, and the rotation of the rotating member 431 can drive the locking rod 420 to move out of the engaging groove 231.

[0096] See Figure 7 , Figure 9 and Figure 10 In this embodiment, the first moving part 4314 extends laterally to enter the first slide groove 441 and is able to move longitudinally within the first slide groove 441.

[0097] In some embodiments, the first moving part 4314 may be a cylindrical structure to facilitate stable and smooth vertical movement of the pressing member 440, and to prevent the first moving part 4314 from affecting the vertical movement of the pressing member 440. In other embodiments, the first moving part 4314 may be a columnar structure so that it can slide longitudinally within the first groove 441.

[0098] See Figure 7 , Figure 9 and Figure 10 In this embodiment, the rotating member 431 can be triangular. The rotating member 431 may include a first corner 4311, a second corner 4313, and a third corner 4315. The rotation axis 4312 of the rotating member 431 is located at the first corner 4311, the second corner 4313 is connected to the pressing member 440, and the third corner 4315 is connected to the locking rod 420.

[0099] The first corner portion 4311 is located below the second corner portion 4313 and the third corner portion 4315. The second corner portion 4313 is positioned away from the door body 210, and the third corner portion 4315 is positioned close to the door body 210. When the user presses the pressing member 440, the pressing member 440 moves vertically downward. The first moving part 4314 drives the second corner portion 4313 to rotate downward around the first corner portion 4311, and the third corner portion 4315 rotates around the first corner portion 4311 away from the door body 210. This causes the locking lever 420 to move away from the door body 210 and disengage from the engaging groove 231, so that the vertical movement of the pressing member 440 can be converted into the lateral movement of the locking lever 420.

[0100] In some embodiments, a rotating shaft 4312 extending laterally may be protruded from the first corner portion 4311. The rotating shaft 4312 is rotatably connected to the inner wall of the workspace 331 so that the rotating member 431 can rotate about the rotating shaft 4312 line.

[0101] In some embodiments, the second corner portion 4313 of the rotating member 431 may also be located near the door body 210, and the pressing member 440 passes through the lower end of the door shelf 300 and is convexly connected to the second corner portion 4313. The first corner portion 4311 is located away from the door body 210, and the third corner portion 4315 is located above the first corner portion 4311 and the second corner portion 4313. The third corner portion 4315 is convexly connected to the locking rod 420, and the pressing member 440 can press vertically upward so that the third corner portion 4315 moves away from the door body 210 around the second corner portion 4313, and the locking rod 420 disengages from the engaging groove 231.

[0102] In other embodiments, the rotating member 431 may also be arc-shaped, straight-lined, or other irregular in shape, as long as it can realize the function of converting the vertical movement of the pressing member 440 into the horizontal movement of the locking lever 420.

[0103] See Figure 7 , Figure 9 and Figure 10 In this embodiment, the transmission structure 430 may further include a connecting rod 432. The two ends of the connecting rod 432 are rotatably connected to the locking rod 420 and the rotating member 431, respectively, with the rotation axis 4312 of the connecting rod 432 parallel to the rotation axis 4312 of the rotating member 431. When the rotating member 431 rotates, it drives the locking rod 420 to extend into or move out of the engaging groove 231 via the connecting rod 432, thereby achieving engagement and disengagement of the locking rod 420 and the guide post 230.

[0104] One end of the connecting rod 432 is hinged to the third corner 4315, and the other end of the connecting rod 432 is hinged to the locking rod 420, so that when the rotating member 431 rotates around the first corner 4311, the rotating member 431 can drive the connecting rod 432 to rotate around the first corner 4311. The connecting rod 432 and the rotating member 431 can rotate relative to each other, and the connecting rod 432 and the locking rod 420 can rotate relative to each other, thereby converting the rotation of the rotating member 431 into the longitudinal movement of the locking rod 420.

[0105] In some embodiments, the transmission structure 430 does not require a connecting rod 432, and the transmission structure 430 only includes a rotating member 431.

[0106] A second groove (not shown in the figure) may be formed on the locking lever 420. The second groove may extend along the moving direction of the pressing member 440. In this embodiment, the second groove extends vertically. A second moving part (not shown in the figure) may be protruded from the rotating member 431, and the second moving part is movably accommodated within the second groove.

[0107] The second moving part is disposed on the triangular portion 4315 of the rotating member 431. The second moving part extends laterally and enters and exits the second slide groove. When the rotating member 431 rotates around the first corner portion 4311, the second moving part moves vertically within the second slide groove, and the second moving part can abut against the inner wall of the second slide groove to drive the locking rod 420 to move longitudinally.

[0108] The structure of the second slide and the second moving part can be set with reference to the structure of the first slide 441 and the first moving part 4314 described above.

[0109] See Figure 7 , Figure 9 and Figure 10 In this embodiment, the locking component 400 may further include an elastic element 450, the two ends of which are respectively connected to the inner wall of the working space 331 and the rotating component 431, so as to keep the locking rod 420 engaged in the engaging groove 231.

[0110] When the user presses the pressing member 440, the pressing member 440 moves vertically and drives the rotating member 431 to rotate. During the rotation of the rotating member 431, the rotating member 431 can drive the locking rod 420 to disengage from the engaging groove 231, and part of the kinetic energy of the rotating member 431 is converted into the elastic potential energy of the elastic member 450.

[0111] After the door shelf 300 is adjusted to the height position, the user removes the pressing member 440. The elastic potential energy in the elastic member 450 is converted into elastic force to drive the rotating member 431 to rotate. When the rotating member 431 rotates, the locking rod 420 can be inserted into and engaged in the engaging groove 231, and the pressing member 440 can be moved upward to extend out of the upper end face of the door shelf 300. This makes it easier for the user to press the pressing member 440 to adjust the height position of the door shelf 300, improve the working efficiency of the locking component 400, and enhance the user experience.

[0112] In some embodiments, the elastic element 450 is an elastic tension spring. One end of the elastic tension spring is connected to the inner wall of the working space 331, and the other end of the elastic tension spring is connected to the rotating element 431, so that the elastic tension spring releases kinetic energy to keep the locking rod 420 engaged in the engaging groove 231.

[0113] In some embodiments, the elastic element 450 can also be a compression spring, so that the tension spring releases kinetic energy to keep the locking rod 420 engaged in the engagement groove 231. In other embodiments, the elastic element 450 can also be a torsion spring. The torsion spring can be sleeved on the rotating shaft 4312.

[0114] In some embodiments, the elastic member 450 may also connect the inner wall of the working space 331 and the locking lever 420, so that the elastic member 450 can apply an elastic force to the locking lever 420, thereby keeping the locking lever 420 engaged in the engaging groove 231. The elastic member 450 may also connect the inner wall of the working space 331 and the pressing member 440, so that the elastic member 450 can apply an elastic force to the pressing member 440, thereby keeping the locking lever 420 engaged in the engaging groove 231.

[0115] See Figure 7 , Figure 9 and Figure 10 In this embodiment, the locking assembly 400 may further include a protective box 410. The locking lever 420, the pressing member 440, and the transmission structure 430 are all housed within the protective box 410 to facilitate the installation, disassembly, and maintenance of the locking assembly 400. A pressing channel 411 may be provided on the protective box 410 relative to the pressing hole 332, and the pressing member 440 is slidably housed within the pressing channel 411 and passes through the door shelf 300 through the pressing hole 332. A locking channel 412 may be provided on the protective box 410 relative to the locking hole 333, and the locking lever 420 is slidably housed within the sliding channel and passes through the locking hole 333 through the door shelf 300.

[0116] When the locking assembly 400 is installed, the pressing member 440, the rotating member 431, the locking rod 420, the connecting rod 432, and the elastic member 450 are installed inside the protective box 410, and then the protective box 410 is placed inside the working space 331. When the protective box 410 is installed inside the working space 331, the pressing member 440 slides in the pressing channel 411 and passes through the pressing hole 332, and the locking rod 420 slides in the locking channel 412 and passes through the locking hole 333.

[0117] In some embodiments, the protective box 410 may have engaging flanges 414 protruding from the pressing channel 411 and the locking channel 412 respectively. The engaging flanges 414 are located on the outside of the protective box 410 and may be arranged around the outer periphery of the locking rod 420 and the pressing member 440.

[0118] When the protective box 410 is installed on the door shelf 300, the two engaging protrusions 414 can extend into and be positioned in the locking hole 333 and the pressing hole 332 respectively. On the one hand, this can improve the connection strength between the protective box 410 and the door shelf 300 and improve the stability of the refrigeration equipment. On the other hand, it can guide the locking rod 420 and the pressing member 440 through the door shelf 300 and prevent the locking rod 420 and the pressing member 440 from abutting against the inner wall of the working space 331.

[0119] In other embodiments, the engaging flange 414 can abut against the inner wall of the working space 331 to stably and reliably confine the protective box 410 within the working space 331, preventing the locking component 400 from moving slightly and improving the reliability and stability of the locking component 400.

[0120] In some embodiments, the rotating member 431 is rotatably connected to the protective box 410. One end of the elastic member 450 is connected to the protective box 410, and the other end of the elastic member 450 is connected to the rotating member 431, so that it can absorb the kinetic energy of the rotating member 431 and release the kinetic energy to drive the rotating member 431 to rotate.

[0121] In some embodiments, the protective box 410 may also be provided with two stop plates 460. The two stop plates 460 are respectively located on both sides of the rotating member 431 in the rotation direction, so as to limit the rotation angle of the rotating member 431, prevent the pressing member 440 and the locking rod 420 from moving completely into the internal space of the protective box 410, and ensure the reliability and stability of the locking assembly 400.

[0122] See Figure 7 , Figure 9 and Figure 10 In this embodiment, the size of the protective box 410 is adapted to the size of the working space 331 so that the protective box 410 can be stably and reliably installed in the door shelf 300 to prevent the protective box 410 from becoming loose relative to the door shelf 300.

[0123] In some embodiments, a locking block 413 is provided on the peripheral sidewall of the protective box 410. A locking groove is recessed on the inner peripheral wall of the working space 331. When the protective box 410 is installed in the working space 331, the locking block 413 engages in the locking groove, thereby limiting the movement of the protective box 410 and preventing the locking rod 420 from accidentally sliding out of the engaging groove 231, ensuring that the door shelf 300 is stably and reliably positioned on the door body 210.

[0124] In other embodiments, the limiting protrusion 320, shelf body 310, protective box 410, rotating member 431, and pressing member 440 may be provided with weight-reducing grooves and / or weight-reducing holes, so as to reduce the weight of the door shelf 300 and the rotating assembly while ensuring the structural strength of the limiting protrusion 320, shelf body 310, protective box 410, rotating member 431, and pressing member 440, making it easier for users to hold and move the door shelf 300.

[0125] See Figures 1 to 10 In this embodiment, when a user places items of different sizes to adjust the height of the door shelf 300, the user's hand holds the door shelf 300 and their fingers press the pressing member 440. The pressing member 440 moves downward and presses down on the first moving part 4314, causing the first moving part 4314 to slide away from the door body 210 within the first sliding groove 441. The movement of the first moving part 4314 drives the rotating member 431 to rotate away from the door body 210 around the rotation axis 4312. The rotation of the rotating member 431 drives the locking rod 420 to disengage from the engaging groove 231 via the connecting rod 432. Part of the rotational kinetic energy of the rotating member 431 is converted into the elastic potential energy of the elastic member 450.

[0126] When the rotating component 431 rotates to a certain angle, it abuts against the stop plate 460, causing the rotating component 431 to stop rotating. At this time, the locking rod 420 disengages from the engaging groove 231, and the user can move the door shelf 300 vertically to quickly adjust the height of the door shelf 300 relative to the door body 210, thereby enabling the door shelf 300 to be used to place items of various shapes and improving the space utilization of the refrigeration equipment.

[0127] After the door shelf 300 is adjusted to the desired height, the finger is removed, and the elastic element 450 applies an elastic force to the rotating element 431, causing the rotating element 431 to rotate around the rotation axis 4312 closer to the door body 210. The rotation of the rotating element 431 has two effects: firstly, the connecting rod 432 drives the locking rod 420 to slide towards the engaging groove 231 within the locking channel 412, causing the engaging groove 231 to extend into and engage within it, thereby limiting the door shelf 300 to the height position of the door body 210; secondly, the first moving part 4314 drives the pressing element 440 to move vertically upwards, protruding from the upper surface of the door shelf 300, thus facilitating subsequent height adjustment by the user.

[0128] The locking structure allows for the conversion between the longitudinal movement of the locking lever 420 and the pressing movement of the pressing member 440, in accordance with ergonomics. This allows users to lock the locking lever 420 and the engaging groove 231 by pressing with their fingers while holding the door shelf 300, making it easier for users and improving their user experience.

[0129] Another embodiment of the locking component 400:

[0130] In this embodiment, a working space 331 may be provided at the lower end of the door shelf 300, and the working space 331 may extend laterally. A locking component 400 may be disposed within the working space 331. The locking component 400 includes a locking lever 420, a pressing member 440, and a rotating member 431.

[0131] The locking lever 420 extends longitudinally. One end of the locking lever 420 is located within the working space 331, and the other end of the locking lever 420 passes through the side wall of the door shelf 300 facing the engagement groove 231.

[0132] The pressing member 440 can extend laterally. One end of the pressing member 440 is located within the working space 331, and the other end of the pressing member 440 passes through the lateral side wall of the door shelf 300 and extends to the outside of the door shelf 300.

[0133] The rotating component 431 is rotatably housed within the working space 331 about a vertical rotation axis 4312. The rotating component 431 is drive-connected to the locking rod 420 and the pressing component 440, and its drive-connection structure refers to the drive-connection structure of the locking assembly 400 in the above embodiment.

[0134] The structure of the locking assembly 400 allows the user's fingers to press the pressing member 440 laterally, thereby driving the locking lever 420 to disengage from the engagement groove 231 via the transmission structure 430.

[0135] In some embodiments, the pressing member 440 can also extend longitudinally. One end of the pressing member 440 is located within the working space 331, and the other end of the pressing member 440 passes through the longitudinal side wall of the door shelf 300 away from the door body 210, so that when the user presses the pressing member 440, the transmission structure 430 converts the pressing movement of the pressing member 440 into the movement of the locking lever 420, so that the locking lever 420 can disengage from the engagement groove 231.

[0136] In other embodiments, the locking lever 420 extends laterally to pass through the lateral sidewall of the door shelf 300. The opening direction of the engaging groove 231 is laterally oriented towards the center of the door shelf 300. The pressing member 440 extends longitudinally to pass through the longitudinal sidewall of the door shelf 300. The transmission structure 430 drivesly connects the pressing member 440 and the locking lever 420 to convert the pressing movement of the pressing member 440 into the lateral movement of the locking lever 420, so that the locking lever 420 can disengage from the engaging groove 231.

[0137] The above embodiments are merely illustrative examples of structures. The structures in each embodiment are not fixed combinations. In the absence of structural conflicts, the structures in multiple embodiments can be arbitrarily combined and used. For example, if the pressing member 440 extends longitudinally to penetrate the longitudinal sidewall of the door shelf 300 away from the door body 210, it can be applied not only to the embodiment where the working space 331 is located at the bottom of the door shelf 300, but also to the embodiment where the working space 331 is located at both ends laterally, so that the pressing movement of the pressing member 440 can be converted into the longitudinal movement of the locking lever 420.

[0138] In some embodiments, the locking assembly 400 may further include an elastic element 450. The elastic element 450 connects the rotating member 431 and the inner wall of the working space 331 to retain the locking lever 420 engaged in the engagement groove 231.

[0139] Although this application has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since this application can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
