[0036] This utility model proposes a hinge structure 1000.

[0037] Please see Figure 1 , Figure 2 as well as Figure 5 In one embodiment of this utility model, the hinge structure 1000 includes a connecting seat 1, a mounting seat 2, and a transmission component; the connecting seat 1 is hidden inside the door body 14, one end of the transmission component is connected to the connecting seat 1, and the other end of the transmission component is exposed in the door body 14 and connected to the mounting seat 2, so that the mounting seat 2 can rotate relative to the connecting seat 1; the mounting seat 2 has a waist-shaped hole 201 through the mounting seat 2 on the side facing the connecting seat 1, and the mounting seat 2 is connected to the object to be installed.

[0038] The connecting seat 1 is used to connect with the door body 14. Correspondingly, the mounting seat 2 is connected with the installation object of the door body 14. The installation object can be a door frame, box 13, or cabinet, etc. After being connected with the installation object, the door body 14 can rotate relative to the installation object through the rotational connection between the mounting seat 2 and the connecting seat 1, thereby realizing the opening and closing of the door body 14.

[0039] To conceal the connecting seat 1, in this embodiment, the upper and lower ends of the door body 14 are connected to the installation object via two hinge structures 1000. Two receiving grooves are formed on the side of the door body 14 facing the installation object, located at the upper and lower ends of the door body 14. The connecting seat 1 of the two hinge structures 1000 can be pre-embedded in the two receiving grooves and fixed to the door body 14 with screws. The connecting seat 1 is connected to the mounting seat 2 via a transmission assembly, and the mounting seat 2 is connected to the installation object of the door body 14. Thus, after the door body 14 is installed, both connecting seats 1 are concealed within the receiving grooves. In other embodiments, several receiving grooves can be provided on the left or right end of the door body for the connecting seat 1 to be installed, thereby achieving the concealment of the connecting seat 1.

[0040] The extension direction of the waist-shaped hole 201 needs to correspond to the position of the door body 14 where the installation object is installed. For example, if the side where the door body 14 is installed is the front side, the corresponding waist-shaped hole 201 is set to extend back and forth, so that the gap between the door body 14 and the installation object can be adjusted.

[0041] In the technical solution of this utility model, the connecting seat 1 is connected to the door body 14, and the connecting seat 1 is rotatably connected to the mounting seat 2 through a transmission component. The mounting seat 2 is connected to the mounting object of the door body 14, allowing the door body 14 to rotate relative to the mounting object. By providing a slotted hole 201 in the mounting seat 2 to connect with the mounting object, the hinge structure 1000 can be adjusted within a certain range during installation, thereby adjusting the gap between the door body 14 and the mounting object and improving the flexibility of the hinge structure 1000. Furthermore, the connecting seat 1 is concealed within the door body 14, minimizing the impact of external environmental factors such as dust and moisture on the connecting seat 1, thus reducing maintenance needs and extending its service life.

[0042] Furthermore, in one embodiment of this utility model, please refer to... Figure 1 and Figure 2 The mounting base 2 has multiple oblong holes 201 arranged in a rectangular array. By providing multiple oblong holes 201, the mounting base 2 can be more precisely adjusted to the appropriate position during installation to meet the installation requirements of the door 14. Furthermore, the rectangular array of oblong holes 201 provides multiple fixing points for the mounting base 2, resulting in a more stable connection after installation and maximizing the use of the space in the mounting base 2, making it suitable for use in space-constrained environments.

[0043] Specifically, in one embodiment of this utility model, please refer to Figure 1The connecting seat 1 has a first mounting hole; the transmission assembly includes a first rotating shaft 3 and a first bearing 4 sleeved on the first rotating shaft 3. The first bearing 4 is located within the first mounting hole, and the end of the first rotating shaft 3 furthest from the connecting seat 1 is connected to the mounting seat 2. The first mounting hole provides a mounting position for the first bearing 4, allowing it to be accurately positioned and ensuring the stability of the transmission assembly. The first bearing 4 reduces friction between the first rotating shaft 3 and the connecting seat 1, ensuring accuracy and smoothness of transmission while maintaining a simple structure, and also facilitating the assembly of the hinge structure 1000. Furthermore, please refer to... Figure 3 and Figure 4 The connecting seat 1 can be installed in the door body 14 in a concealed manner, and then connected to the mounting seat 2 through the first pivot 3. The concealed installation makes the connecting seat 1 not exposed, thus providing a cleaner and more beautiful appearance. Since the connecting seat 1 is hidden inside the door body 14, the influence of external environmental factors such as dust and moisture on the connecting seat 1 is small, which helps to reduce maintenance needs and extend service life.

[0044] To limit the axial movement of the first bearing 4, in one embodiment of this invention, please refer to... Figure 1 The hinge structure also includes a first pressure plate 5 and a first end plate 6. The first pressure plate 5 is sleeved on the first rotating shaft 3 and covers the first mounting hole. The first end plate 6 is located inside the first mounting hole, and the first bearing 4 is located between the first end plate 6 and the first pressure plate 5. Through the cooperation of the first pressure plate 5 and the first end plate 6, the position of the first bearing 4 can be precisely limited, ensuring the axial stability and accuracy of the first bearing 4. Before the first bearing 4 is installed into the first mounting hole, the first end plate 6 is placed into the first mounting hole to fill part of the space, and then the first bearing 4 is installed. In this way, the first end plate 6 can be close to or pressed against one end of the first bearing 4. Through this tight cooperation, the axial movement of the first bearing 4 can be effectively limited. By limiting the axial movement of the first bearing 4, unnecessary friction and wear can be reduced, helping to extend the service life of the first bearing 4. The first pressure plate 5, covering the first mounting hole, can press the outer ring of the first bearing 4, effectively preventing the first bearing 4 from dislodging from the first mounting hole when subjected to external force.

[0045] Specifically, in one embodiment of this utility model, please refer to Figure 2The connecting seat 1 has a second mounting hole and a third mounting hole connected from top to bottom. The transmission assembly includes a second rotating shaft 7, a second bearing 8 and a load-bearing bearing 9 sleeved on the second rotating shaft 7. The second bearing 8 is located in the second mounting hole, and the load-bearing bearing 9 is located in the third mounting hole. The end of the second bearing 8 away from the connecting seat 1 is connected to the mounting seat 2. The design of the second bearing 8 is similar to the function of the first bearing 4 in the above embodiment. The second bearing 8 can reduce the friction between the second rotating shaft 7 and the connecting seat 1, ensuring the accuracy and smoothness of the transmission. The setting of the load-bearing bearing 9 enables the hinge structure 1000 to bear a larger axial force, increasing the load-bearing capacity of the hinge structure 1000, and is suitable for installation at the lower end of the door body 14 or in positions with high load-bearing requirements.

[0046] Furthermore, in one embodiment of this utility model, please refer to... Figure 2 The hinge structure also includes a second pressure plate 10 and a second end plate 11. The second pressure plate 10 covers the second mounting hole, and the second end plate 11 is located inside the second mounting hole, between the second bearing 8 and the second pressure plate 10. The cooperation of the second pressure plate 10 and the second end plate 11 precisely restricts the position of the second bearing 8, ensuring its axial stability and accuracy. After the second bearing 8 is installed into the second mounting hole, the second end plate 11 is then installed into the second mounting hole, and finally the second pressure plate 10 is placed over the second mounting hole. In this way, the second end plate 11 fills the gap between the second bearing 8 and the second pressure plate 10, and can be close to or against one end of the second bearing 8. Its cooperation with the second pressure plate 10 effectively restricts the axial movement of the second bearing 8. By restricting the axial movement of the second bearing 8, unnecessary friction and wear are reduced, helping to extend the service life of the first bearing 4. The second pressure plate 10 can press the outer ring of the second bearing 8, effectively preventing the second end plate 11 or the second bearing 8 from dislodging from the second mounting hole under external force.

[0047] To limit the position of the load-bearing bearing 9, please refer to one embodiment of this utility model. Figure 2 The hinge structure also includes a third pressure plate 12, which is sleeved on the second rotating shaft 7 and covers the third mounting hole. The third pressure plate 12 can press the outer ring of the load-bearing bearing 9, effectively preventing the load-bearing bearing 9 from coming out of the third mounting hole when subjected to external force, thus improving safety.

[0048] Specifically, in one embodiment of this utility model, the first bearing 4 is a deep groove ball bearing. Deep groove ball bearings have high radial load capacity, making them suitable for bearing large loads; they also have a low coefficient of friction, which helps reduce friction in the hinge during operation, making the opening and closing of the door 14 smoother; and they have a long service life, reducing the frequency of maintenance and replacement. In another embodiment of this utility model, the second bearing 8 is also a deep groove ball bearing, and the load-bearing bearing 9 is a planar bearing. Planar bearings can withstand very high axial loads, and their simple structure and relatively low manufacturing cost help reduce the cost of the overall hinge structure 1000.

[0049] Please see Figure 3 This utility model also proposes a storage device 2000, which includes a housing 13, a door 14, and two hinge structures 1000. The specific structure of the hinge structure 1000 is as described in the above embodiments. Since this storage device 2000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The housing 13 has an opening, and the door 14 has two receiving grooves on the side facing the housing 13. The two receiving grooves are located at the upper and lower ends of the door 14, respectively. Two connecting seats 1 are respectively disposed in the two receiving grooves, and two mounting seats 2 are connected to the housing 13. Specifically, a hinge structure 1000 with a load-bearing bearing 9 is selected to connect the lower end of the door body 14 and the housing 13, and a hinge structure 1000 with a transmission assembly having a first rotating shaft 3 is selected to connect the upper end of the door body 14 and the housing 13. In this installation configuration, the connecting seat 1 of the hinge structure 1000 at the upper end of the door body 14 is located at the lower end of the mounting seat 2, and the connecting seat 1 of the hinge structure 1000 at the lower end of the door body 14 is located at the upper end of the mounting seat 2, that is, the door body 14 is positioned between the two mounting seats 2. This reduces the overall cost while ensuring the load-bearing capacity of the hinge structure 1000. Please refer to [link / reference needed]. Figure 5 Two receiving slots are located at the upper and lower ends of the door body 14, respectively. The connecting seats 1 of the two hinge structures 1000 can be pre-embedded in the two receiving slots and fixed to the door body 14 with screws. The connecting seats 1 are connected to the mounting seats 2 via a transmission assembly. The mounting seats 2 are connected to the mounting objects of the door body 14. Thus, after the door body 14 is installed, both connecting seats 1 are hidden within the receiving slots. This concealed installation prevents the connecting seats 1 from being exposed, providing a cleaner and more aesthetically pleasing appearance. Furthermore, because the connecting seats 1 are hidden inside the door body 14, external environmental factors such as dust and moisture have less impact on them, helping to reduce maintenance needs and extend their service life. In other embodiments, the relative positions of the connecting seats 1 and the mounting seats 2 of the hinge structure 1000 can be reversed, thereby concealing the mounting seats 2 within the housing 13.

[0050] Furthermore, in one embodiment of this utility model, please refer to... Figure 4 The door 14 is also equipped with a transparent observation window 1401, through which the contents of the cabinet 13 can be observed. The transparent observation window 1401 uses double-glazed glass, which has good heat insulation properties, making it suitable for special applications, such as refrigerators for storing specimens. In addition, a heating structure can be provided for the transparent observation window 1401 to prevent the outer glass from fogging up and affecting observation.

[0051] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
