For example, in a cabinet, the cabinet door is supported and hinged by the hinge, so that the cabinet door can rotate relative to the cabinet body, thereby opening or closing the cabinet door. However, existing doors, windows, and cabinets all have the following defects:

[0003] 1. The connection between the cabinet body, hinges, and cabinet doors (or: door frame, hinges, doors. Or: window frame, hinges, window doors) is not secure. The main reason is that the connection between the hinges and the cabinet body, and the connection between the hinges and the cabinet doors are not secure, which makes the cabinet doors easily tilt after long-term use and cannot be closed normally. In summary, the pivot structure used in doors, windows, and cabinets is not strong enough.

DETAILED DESCRIPTION

[0040] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0041] See also Figure 1-Figure 5 , shows a pivot structure of a preferred embodiment of the present invention, including a support frame 1, a hinge 2, and a plate body 3. The side plates of the support frame 1 enclose an inner cavity 11. The hinge 2 includes a fixed block 21 and a support block 22. The fixed block 21 is located in the inner cavity 11 and is fixedly connected to the support frame 1. The support block 22 is connected to the fixed block 21 and extends from the inside of the inner cavity 11 to the outside of the inner cavity 11. The support block 22 is provided with a through hole 2221 (see Fig.10 , Fig.13 ), the through hole 2221 is located outside the inner cavity 11, the plate body 3 is provided with a clearance groove 31, and the two opposite side walls of the clearance groove 31 are respectively provided with a first limiting hole 331 (see Figure 6 ); the pivot structure also includes a pivot shaft 4 (see Figure 5), both ends of the pivot shaft 4 are respectively located in one of the first limiting holes 331 of the give way slot 31, the pivot shaft 4 is sleeved in the through hole 2221, and the plate body 3 can rotate around the through hole 2221; when the plate body 3 switches from a closed state to an open state, the plate body 3 rotates around the through hole 2221 and can rotate the plate body 3 180°; when the plate body 3 switches from an open state to a closed state, the plate body 3 rotates around the through hole 2221 and can cover the inner cavity 11; when the plate body 3 is in a closed state, the entire support block 22 or a part of the support block 22 is located in the give way slot 31.

[0042] It can be understood that the present pivot structure is achieved by fixing the fixing block 21 on the supporting frame 1, and then supporting the plate body 3 through the supporting block 22 connected to the fixing block 21, and the through hole 2221 of the supporting block 22 is connected to the pivot shaft 4, and the two ends of the pivot shaft 4 are respectively located in one of the limit block holes of the door plate (i.e., the clearance groove 31), thereby realizing a secure connection between the plate body 3 and the supporting block 22. Since the plate body 3 is provided with the clearance groove 31, when the plate body 3 is in a closed state, the entire supporting block 22 or a part of the supporting block 22 is located in the clearance groove 31. Such arrangement enables the support block 22 to extend from the inside of the inner cavity 11 to the outside of the inner cavity 11, so that when the plate body 3 is switched from a closed state to an open state, the plate body 3 rotates around the through hole 2221, and the plate body 3 can rotate 180° without being interfered by the support frame 1; and when the plate body 3 is switched from an open state to a closed state, the plate body 3 rotates around the through hole 2221, and the plate body 3 can cover the inner cavity 11 without shaking.

[0043] It should be noted that when the plate body 3 is in the closed state, the entire support block 22 can be located in the clearance groove 31, or a portion of the support block 22 can be located in the clearance groove 31. For example, the support block 22 can be directly fixed to the fixed block 21, and the entire support block 22 can be located in the clearance groove 31; or a portion of the support block 22 can be connected to the fixed block 21, so that the support block 22 can be adjusted up and down, front and back, and the other portion of the support block 22 is located in the clearance groove 31.

[0044] Better, see Figure 6The plate body 3 includes a horizontal plate 32 and a vertical plate 33. The horizontal plate 32 is fixedly connected to the vertical plate 33 and arranged in an L-shaped structure. The positioning groove 31 extends from one side of the horizontal plate 32 in a direction perpendicular to the vertical plate 33 and passes through the horizontal plate 32 and the vertical plate 33 in sequence. The first limiting hole 331 is opened in the horizontal plate 32 and is located on the side of the horizontal plate 32 away from the vertical plate 33. When the plate body 3 is in a closed state, the vertical plate 33 is located between the horizontal plate 32 and the fixed block 21. In this way, when the horizontal plate 32 is connected to the pivot shaft 4 through the first limiting hole 331, the vertical plate 33 is at a certain distance from the pivot shaft 4, so that the plate body 3 can rotate and open a larger angle (i.e., more than 180°). Furthermore, when the vertical plate 33 switches from the open state to the closed state, since the vertical plate 33 is at a certain distance from the pivot shaft 4, the vertical plate 33 can fit the port of the inner cavity 11 and better cover the inner cavity 11, and at this time the entire support block 22 or a part of the support block 22 is located in the clearance groove 31. It should be further explained here that the installation of the L-shaped structure must meet the following requirements: when the plate body 3 is in the closed state, the vertical plate 33 is located between the horizontal plate 32 and the fixed block 21; that is, when the plate body 3 is opened 180°, the horizontal plate 32 is located between the vertical plate 33 and the fixed block 21; only in this way can the plate body 3 be opened and closed normally.

[0045] Connection method 1 of the support block 22 and the fixed block 21: Preferably, the support block 22 is fixedly connected to the fixed block 21, and the length of the support block 22 is equal to the width of the make-way slot 31. When the plate body 3 is in a closed state, the length direction of the support block 22 is consistent with the direction of the width of the make-way slot 31 (wherein, when the support frame 1 is placed normally, the direction of the width is parallel to the horizontal plane), and the entire support block 22 is located in the make-way slot 31. By setting the length of the support block 22 to be equal to the width of the make-way slot 31, the support block 22 will not be exposed outside the plate body 3 when the plate body 3 is in a closed state, so that the support block 22 can be prevented from being damaged by accidental collision, thereby further improving the reliability of the present pivot structure.

[0046] The second connection method between the support block 22 and the fixed block 21: preferably, see Figure 7-Figure 14 The hinge 2 also includes a guide member 23 (see Fig. 9 ), the support block 22 includes an extension portion 222 and an insertion portion 221, and the side of the fixing block 21 near the extension portion 222 is recessed from outside to inside to form a mounting cavity 211. The guide member 23 is inserted into the mounting cavity 211 along the port of the mounting cavity 211 and fixed in the mounting cavity 211. The guide member 23 has a groove 231 that passes through both sides of the guide member 23 (see Fig. 9), the extension direction of the groove 231 is consistent with the extension direction of the installation cavity 211. The insertion portion 221 of the support block 22 extends into the groove 231 from the port of the installation cavity 211, and can make a reciprocating linear motion along the extension direction of the groove 231, so that the insertion portion 221 can be fine-tuned along the direction of the groove 231 (that is, the hinge 2 can be fine-tuned along the direction of the groove 231). The insertion portion 221 is connected to a first fastener 2211 (see Figure 8 , Fig. 9 ), the guide member 23 is provided with a first adjustment hole 2341, and the first fastener 2211 is used to fix the insertion portion 221 to the guide member 23. The first adjustment hole 2341 is larger than the diameter of the first fastener 2211, so that when the insertion portion 221 is loosened from the guide member 23, the relative position of the first fastener 2211 and the first adjustment hole 2341 can be adjusted; that is, by loosening the first fastener 2211, the hinge 2 can be fine-tuned along the direction of the groove 231, and by tightening the first fastener 2211, the insertion portion 221 can be fixed on the guide member 23. Fine-tuning the hinge 2 can not only adjust the position of the hinge 2 so that the plate body 3 can better cover the inner cavity 11, but also, fine-tuning the hinge 2 is more conducive to preventing the hinge 2 from being weakened due to long-term local force on the hinge 2, thereby improving the reliability of the hinge 2. Among them, the first fastener 2211 can be a conventional element such as a screw, a rivet, a bolt, a pin, etc.

[0047] Further, see Fig. 9 The guide member 23 includes a left side plate 232, a right side plate 233 and a bottom plate 234, the bottom plate 234 is located between the left side plate 232 and the right side plate 233, and the left side plate 232, the right side plate 233 and the bottom plate 234 enclose the groove 231 (see Fig. 9 ); the first adjustment hole 2341 is provided on the bottom plate 234; the bottom plate 234 is fixedly connected with a second fastener 2342 (see Figure 8 , Fig. 9 ), the insertion portion 221 is provided with a second adjustment hole 2212, the second fastener 2342 extends into the second adjustment hole 2212, and the second adjustment hole 2212 is larger than the diameter of the second fastener 2342, so that the second adjustment hole 2212 can move relative to the second fastener 2342, and the second adjustment hole 2212 is limited by the second fastener 2342. It can be understood that in order to achieve fine adjustment of the insertion portion 221 and control the maximum adjustment range of the insertion portion 221, this embodiment sets the second adjustment hole 2212 to be larger than the diameter of the second fastener 2342, and fixes the second fastener 2342 to the bottom plate 234 of the guide member 23, so that the movement range of the second adjustment hole 2212 is controlled by the second fastener 2342. Among them, the second fastener 2342 can be a conventional element such as a screw, a rivet, a bolt, a pin, etc.

[0048] Furthermore, the width of the protruding portion 221 is smaller than the distance between the left side plate 232 and the right side plate 233 (see Figure 7 , Fig. 9 ), so that the insertion portion 221 can move closer to or away from each other relative to the left side plate 232 in the groove 231. The fixing block 21 is fixedly connected with the third fastener 212, and the insertion portion 221 is provided with a third adjustment hole 2213, the third adjustment hole 2213 is larger than the aperture of the third fastener 212, and the guide member 23 is provided with a clearance hole 2343, and the third fastener 212 passes through the clearance hole 2343 and extends into the third adjustment hole 2213. It can be understood that the clearance hole 2343 of the guide member 23 ensures that the third fastener 212 can pass through and extend into the third adjustment hole 2213, and the third fastener 212 limits the movement range of the third adjustment hole 2213. The width of the insertion portion 221 is smaller than the distance between the left side plate 232 and the right side plate 233. This arrangement enables the insertion portion 221 to be fine-tuned in the direction of approaching the left side plate 232 or away from the left side plate 232. Furthermore, by combining the second fastener 2342 and the second adjusting member, and combining the third fastener 212 and the third adjusting member, they can restrain and support each other, and ensure the connection reliability of the insertion portion 221, and prevent the insertion portion 221 from being adjusted too much to cause the plate 3 to collide with the hinge 2. The third fastener 212 can be a conventional element such as a screw, a rivet, a bolt, a pin, etc.

[0049] Preferably, see Fig. 9 , Fig.10 The end of the extending portion 221 away from the fixed block is movably connected to a guide post 2214 (see Fig. 9), the insertion portion 221 can move along the axial direction of the guide column 2214, the left side plate 232 and the right side plate 233 of the guide member 23 are both provided with a second limiting hole 235, one end of the guide column 2214 abuts against the inner wall of the installation cavity 211, and the other end of the guide column 2214 passes through the second limiting hole 235 of the left side plate 232, the groove 231, and the second limiting hole 235 of the right side plate 233 in sequence, and abuts against the inner wall of the installation cavity 211. In addition, the diameter of the guide column 2214 is smaller than the second limiting hole 235, so that the guide column 2214 can move in the second limiting hole 235, that is, after the second guide column 2214 is matched with the second limiting hole 235, the second guide column 2214 can still move, thereby preventing the second guide column 2214 from limiting the fine adjustment of the insertion portion 221. Moreover, by abutting the inner wall of the installation cavity 211 with both ends of the guide column 2214, when the insertion portion 221 moves axially along the guide column 2214, the guide column 2214 can guide the insertion portion 221, and the fine-tuning process is more reliable, and the degree of damage to the internal structure of the pivot structure is reduced each time; further, because the two ends of the second guide column 2214 abut against the inner wall of the installation cavity 211, when the insertion portion 221 is fine-tuned along the direction of the groove 231, the adjustment process of the insertion portion 221 is also very stable.

[0050] It should be further explained that the pivot structure in this embodiment can make the insertion portion 221 finely adjusted along the direction of the channel 231 under the premise of loosening the first fastener 2211, and can also make the insertion portion 221 finely adjusted along the direction of approaching or moving away from the left side plate 232. That is, when the pivot structure is placed normally, the insertion portion 221 can be adjusted forward and backward and up and down.

[0051] In addition, the pivot structure can be applied to many products, such as:

[0052] The cabinet includes the pivot structure. Preferably, the cabinet further includes an outer frame 5, the outer frame 5 has a cavity 51, and the support frame 1 is embedded in the cavity 51. The outer frame 5 protects the support frame, which can prevent the support frame from being hit, especially prevent the hinge 2 from being hit, thereby improving the reliability of the cabinet.

[0053] A window comprises the pivoting structure.

[0054] A door comprises the pivoting structure.

[0055] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
