[0004] To solve the above problems, the present invention adopts the following technical solution:
[0005] According to a first aspect of the present invention, an embodiment of the present invention provides a lifting pivot assembly, including a lower pivot seat and a lower connector. The lower connector is disposed above the lower pivot seat and is used to connect to a door body. The bottom of the lower connector is provided with a downwardly extending lower pivot and a lifting sub-key. The lower pivot seat is provided with a lower bushing and a lifting female key. The lower pivot is inserted into the lower bushing and can rotate and move vertically within the lower bushing. The lifting female key is sleeved on the outside of the lower bushing. The top of the lifting female key has a lifting inclined surface. The lower end of the lifting sub-key abuts against the lifting inclined surface. During the opening and closing of the door body, the lower end of the lifting sub-key moves along the lifting inclined surface. In the rotation direction of the lifting sub-key, the height of the lifting inclined surface gradually increases, and the lifting inclined surface has a highest point and a lowest point. When the door body is in the closed state, the lower end of the lifting sub-key is located at the lowest point. During the opening of the door body, the lower end of the lifting sub-key moves towards the highest point.
[0006] In some embodiments, the top of the lifting female key has a protrusion, one side of the protrusion forms the lifting ramp, the apex of the protrusion forms the highest point, and the lowest point of the protrusion forms the lowest point.
[0007] In some embodiments, two protrusions are provided, and the lowest points of the lifting ramps of the two protrusions are connected.
[0008] In some embodiments, both sides of the protrusion form the lifting ramp, and the lowest points of the lifting ramps of the two protrusions that are adjacent to each other are connected; two lifting sub-keys are provided accordingly, and the two lifting sub-keys abut against the lifting ramps of the two protrusions that are far apart from each other.
[0009] In some embodiments, the top surface of the lower rotating shaft seat is provided with a mounting groove, and the lifting female key is placed in the mounting groove; both the lifting female key and the inner wall of the mounting groove are provided with limiting structures, and the limiting structure of the lifting female key and the limiting structure on the inner wall of the mounting groove are adapted to each other to restrict the rotation of the lifting female key in the mounting groove.
[0010] In some embodiments, the limiting structure of the lifting female key is a protrusion disposed on the periphery of the lifting female key, and the limiting structure on the inner wall of the mounting groove is a groove adapted to the protrusion, wherein the protrusion is embedded in the groove.
[0011] In some embodiments, the top surface of the lower rotating shaft seat is provided with a through mounting hole, and the top surface of the lower rotating shaft seat is also covered with a cover plate, which covers the mounting hole.
[0012] In some embodiments, the lower connector includes a lower base plate, a first pressure cover, a second pressure cover, a first pad, and a second pad. The first pressure cover and the second pressure cover are located on both sides of the door body, and the first pressure cover and the second pressure cover are connected together by screws. The first pad is placed between the first pressure cover and the door body, and the second pad is placed between the second pressure cover and the door body. The lower base plate is connected to the first pressure cover or the second pressure cover. The lower pivot and the lifting key are both fixed to the bottom surface of the lower base plate.

[0029] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.
[0030] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0031] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.
[0032] An embodiment of this utility model provides a lifting shaft assembly, such as... Figure 1-4 As shown, the device includes a lower pivot seat 100 and a lower connector 200. The lower connector 200 is positioned above the lower pivot seat 100 and is used to connect with the door body 10. Therefore, the door body 10 and the lower connector 200 are linked. When the door body 10 rotates, the lower connector 200 rotates accordingly. The bottom of the lower connector 200 is provided with a downwardly extending lower pivot 201 and a lifting key 202. The lower pivot seat 100 is provided with a lower bushing 110 and a lifting key 300. The lower pivot 100 is inserted into the lower bushing 110 and can rotate within the lower bushing 110, allowing the door body 10 to rotate relative to the lower pivot seat 100. At the same time, the lower pivot 100 can also move vertically within the lower bushing 110, which provides the condition for the door body 10 to move in the vertical direction.
[0033] The lifting key 300 is sleeved on the outside of the lower bushing 110, and its shape can be similar to a cylinder. The top of the lifting key 300 has a lifting ramp 310, and the lower end of the lifting key 202 abuts against the lifting ramp 310. During the opening and closing of the door 10, the lower end of the lifting key 202 moves along the lifting ramp 310. In the rotation direction of the lifting key 202, the height of the lifting ramp 310 gradually increases, and the lifting ramp 310 has a highest point 311 and a lowest point 312. When the lifting key 202 moves along the lifting ramp 310, it can be raised or lowered according to the change in the height of the lifting ramp 310, which in turn causes the door 10 to rise or fall accordingly. When the door 10 is in the closed state, the lower end of the lifting key 202 is at its lowest point, and the distance between the door 10 and the ground is minimized, which can ensure the waterproofness of the door 10. During the opening of the door 10, the lower end of the lifting key 202 moves towards its highest point 311, gradually increasing the height of the lifting key 202. This lifts the door 10 upwards, making it relatively farther from the ground, reducing the resistance to opening and facilitating opening. During the closing of the door 10, the height of the door 10 is greater than its height when closed, which also reduces the resistance to closing and facilitates closing.
[0034] by Figure 1 and Figure 2 For example, we can see Figure 2 Both the lower connecting piece 200 and the door body 10 are lifted relative to the lower pivot seat 100, and the door body 10 is relatively far away from the ground, making it easier to open and close the door.
[0035] In some embodiments, such as Figure 3 and Figure 4 As shown, the top of the lifting female key 300 has a protrusion 320, one side of the protrusion 320 forms a lifting ramp 310, the highest point 311 is formed at the apex of the protrusion 320, and the lowest point of the protrusion 320 forms the lowest point. In this embodiment, the protrusion 320 forms a lifting ramp 310 with gradually changing height, and the lower end of the lifting female key 202 will move along the surface of the protrusion 320.
[0036] Furthermore, two protrusions 320 are provided, each with a lifting ramp 310, and the lowest points 312 of the lifting ramps 310 of the two protrusions 320 are connected. When the door 10 is in the closed state, the lower end of the lifting key 202 is located at the connection point of the lifting ramps 310 of the two protrusions 320. When the door 10 rotates in one direction, i.e., opens in one direction, the lifting key 202 moves accordingly along the lifting ramp 310 of one of the protrusions 320. When the door 10 rotates in the other direction, i.e., opens in the other direction, the lifting key 202 moves accordingly along the lifting ramp 310 of the other protrusion 320. This allows the door 10 to be lifted during both-way opening processes, making both-way opening relatively smooth and convenient for users to open the door in either direction.
[0037] Furthermore, both sides of the protrusion 320 form lifting ramps 310, totaling four lifting ramps 310. The lowest points of the lifting ramps 310 of two adjacent protrusions 320 are connected. Figure 4 For example, the lifting ramps 310 on the same side of the two protrusions 320 are adjacent to each other, and the lowest points of the adjacent lifting ramps 310 are connected, while the lifting ramps 310 on different sides of the two protrusions 320 are far apart from each other.
[0038] Two lifting keys 202 are provided, each abutting against the mutually distant lifting ramps 310 of the two protrusions 320. When one lifting key 202 moves upward along the lifting ramp 310 of one protrusion 320, the other lifting key 202 also moves upward along the lifting ramp 310 of the other protrusion 320. When one lifting key 202 moves downward along the lifting ramp 310 of one protrusion 320, the other lifting key 202 also moves downward along the lifting ramp 310 of the other protrusion 320. Thus, the two protrusions 320 and the two lifting keys 202 work together to lift the door 10, which can improve the lifting effect and keep the door 10 stable during the lifting process.
[0039] In some embodiments, such as Figure 3 and Figure 4 As shown, the top surface of the lower pivot seat 100 is provided with a mounting groove 120, in which the lifting nut 300 is placed. This structural design facilitates the installation of the lifting nut 300 onto the lower pivot seat 100 and makes it easy to replace the lifting nut 300 if it is damaged. Furthermore, the weight of the door will press the lifting nut 300 into the mounting groove 120, eliminating concerns about it easily detaching from the groove.
[0040] Both the lifting key 300 and the inner wall of the mounting groove 120 are provided with limiting structures. The limiting structure of the lifting key 300 and the limiting structure on the inner wall of the mounting groove 120 are adapted to each other to restrict the lifting key 300 from rotating in the mounting groove 120. Therefore, during the rotation of the door, the lateral thrust of the lifting key 202 on the lifting ramp 310 will not cause the lifting key 300 to rotate, thus ensuring the function of the lifting key 300 in lifting the door.
[0041] Furthermore, the limiting structure of the lifting key 300 is a protrusion 310 disposed on the circumferential surface of the lifting key 300, and the limiting structure on the inner wall of the mounting groove 120 is a groove 121 adapted to the protrusion 310. The protrusion 310 is embedded in the groove 121, thereby restricting the rotation of the lifting key 300 in the mounting groove 120. This limiting structure has the advantages of simple structure and easy assembly. Multiple protrusions 310 can be provided and evenly distributed on the circumferential surface of the lifting key 300. Correspondingly, multiple grooves 121 can also be provided to improve the limiting effect.
[0042] In some embodiments, such as Figure 3 and Figure 4 As shown, the top surface of the lower shaft seat 100 is provided with a through mounting hole 130, through which screws and other connecting parts can be inserted to fix the lower shaft seat 100. At the same time, the top surface of the lower shaft seat 100 is also covered with a cover plate 140, which covers the mounting hole 130, protecting the screws and other connecting parts from rusting or damage, and improving the aesthetics.
[0043] In some embodiments, such as Figure 2 and Figure 3 As shown, the lower connector includes a lower base plate 280, a first pressure cover 210, a second pressure cover 220, a first pad 230, and a second pad 240. The first pressure cover 210 and the second pressure cover 220 are located on both sides of the door body 10, and are connected together by a first screw 250. The door body 10, the second pressure cover 220, the first pad 230, and the second pad 240 can all be provided with through holes. The first pressure cover 210 is provided with a threaded hole adapted to the first screw 250. The first screw 250 passes through the through hole and is fixed in the threaded hole, so that the first pressure cover 210 and the second pressure cover 220 clamp and fix the door body 10 from both sides.
[0044] The first pad 230 is placed between the first pressure cover 210 and the door body 10, and the second pad 240 is placed between the second pressure cover 220 and the door body 10, providing cushioning and protection for the door body 10 to prevent damage. The lower base plate 280 is connected to either the first pressure cover 210 or the second pressure cover 220, and the lower pivot 201 and the lifting key 202 are both fixed to the bottom surface of the lower base plate 280.
[0045] The perforation on the second pressure cap 220 can be a countersunk hole 221. The head of the first screw 250 is inserted into the countersunk hole 221. The lower decorative cap 270 can cover the countersunk hole 221 to protect the first screw 250, making it less prone to rust or damage, and improving its aesthetics.

The upper pivot 501 is inserted into the upper bushing and can rotate in the upper bushing, so that the door body 10 can rotate relative to the upper pivot seat 400. At the same time, the upper pivot 501 can move vertically in the upper bushing. When the door body 10 is lifted, the upper pivot 501 moves vertically upward in the upper bushing so as not to affect the lifting of the door body 10.
[0048] In some embodiments, such as Figure 7 As shown, the upper connector includes an upper base plate 580, a third pressure cover 510, a fourth pressure cover 520, a third pad 530, and a fourth pad 540. The third pressure cover 510 and the fourth pressure cover 520 are located on both sides of the door body, and are connected together by a second screw 550. The door body, the fourth pressure cover 520, the third pad 530, and the fourth pad 540 can all be provided with through holes. The third pressure cover 510 is provided with a threaded hole adapted to the second screw 550. The second screw 550 passes through the through hole and is fixed in the threaded hole, so that the third pressure cover 510 and the fourth pressure cover 520 clamp and fix the door body from both sides.
[0049] The third pad 530 is placed between the third pressure cover 510 and the door body, and the fourth pad 540 is placed between the fourth pressure cover 520 and the door body, providing cushioning and protection for the door body to prevent damage.
