[0031] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Example 1:

[0033] This embodiment provides a multifunctional fitness bed, such as Figure 1-Figure 7 As shown, the bed frame 1 includes a first adjustment plate 2, a second adjustment plate 3, a telescopic support rod 4, and a connecting rod 5. Specifically, the bed frame 1 includes legs, a bed support frame, and a bed board. The legs are connected to the four corners of the bed support frame to provide support, and the bed board is installed within the bed support frame. The bed frame 1 can be made of an alloy material, which has good support strength. The bed board can be made of a leather mattress, which has good wear resistance and comfort. The first adjustment plate 2 and the second adjustment plate 3 can also be made of an alloy material.

[0034] The first and second adjustment plates 2 and 3 are respectively connected perpendicularly to the left and right sides of the bed frame 1 relative to the bed surface 11 of the bed frame 1 and extend upward from the bed frame 1. The height of the first adjustment plate 2 is greater than that of the second adjustment plate 3. The bed surface 11 of the bed frame 1 can be the surface of a mattress. The length of the connecting edges of the first and second adjustment plates 2 and 3 to the bed frame is at least twice the width of the telescopic support rod 4.

[0035] One end of the telescopic support rod 4 is rotatably connected to the bottom side of the second adjustment plate 3 through a first fulcrum 41. The first fulcrum 41 of the telescopic support rod 4 can be connected to the second adjustment plate 3 through a connecting shaft 48. Specifically, the telescopic support rod 4 is connected to the connecting shaft 48 through a bearing to facilitate the rotation of the telescopic support rod 4 and change the angle between the telescopic support rod 4 and the bed surface.

[0036] The other end of the telescopic support rod 4 extends beyond the second adjustment plate 3 and connects to the edge of the second adjustment plate 3 via a second fulcrum 42. The telescopic support rod 4 is connected to the second adjustment plate 3 via a first fulcrum 41 and a second fulcrum 42. This ensures a secure connection between the telescopic support rod 4 and the second adjustment plate 3, maintaining a stable angle between the telescopic support rod 4 and the bed surface. The end of the telescopic support rod 4, away from the first fulcrum 41, has a third fulcrum 43.

[0037] One end of the connecting rod 5 is perpendicularly connected to the third fulcrum 43 of the telescopic support rod 4. The other end of the connecting rod 5 can be inserted vertically into the first connection hole 21 at different locations on the first adjustment plate 2. The connecting rod 5 is arranged parallel to the bed surface, supported by the first adjustment plate 2, the second adjustment plate 3, and the telescopic support rod 4. The first adjustment plate 2 directly supports one end of the connecting rod 5, while the second adjustment plate 3 supports the other end of the connecting rod 5 through the telescopic support rod 4.

[0038] The multifunctional fitness bed of this embodiment supports both ends of the connecting rod 5 by connecting the first and second adjusting plates 2 and 3 to the bed frame. Compared to conventional support systems that connect support rods to the bed frame, the first and second adjusting plates 2 and 3 increase the length of the connection to the bed frame, thereby increasing the stability of the connection to the bed frame, thereby enhancing the support strength of the connecting rod and providing better support stability. Because the first fulcrum 41 of the telescopic support rod 4 is rotatably connected to the second adjusting plate 3, when the telescopic support rod 4 rotates relative to the second adjusting plate 3, the other end of the connecting rod 5 is inserted into the corresponding first connecting hole 21 on the first adjusting plate 2, thereby adjusting the position and height of the connecting rod 5 along the length of the bed frame. This provides high flexibility in use, and the adjustable length of the telescopic support rod 4 further increases the flexibility of adjusting the height of the connecting rod 5, which can meet the different exercise needs of different people.

[0039] In a preferred embodiment, the first adjustment plate 2 has two groups of first connection holes 21. Both groups of first connection holes 21 are arranged in an arc shape, with one group of first connection holes 21 positioned parallel to and above the other group of first connection holes 21. When the telescopic support rod 4 is adjusted to different heights, the connecting rod 5 connects to different groups of first connection holes 21. When the telescopic support rod 4 is rotated to different angles relative to the second adjustment plate 3, the connecting rod 5 connects to first connection holes 21 at different arc positions within the same group.

[0040] The second adjustment plate 3 is provided with a plurality of second connection holes 31 arranged in an arc shape. When the telescopic support rod 4 is rotated to different angles relative to the second adjustment plate 3, the first fulcrum of the telescopic support rod 4 is connected to the bottom side of the second adjustment plate 3, and the second fulcrum 42 of the telescopic support rod 4 is connected to a different second connection hole 31.

[0041] The line connecting the center point of the arc-shaped arrangement of each group of first connecting holes 21 and the center point of the arc-shaped arrangement of the second connecting holes 31 is arranged parallel to the axis of the connecting rod 5, so that a stable support frame is formed between the first adjustment plate 2, the second adjustment plate 3, the bed frame and the connecting rod 5.

[0042] In a preferred embodiment, the first adjustment plate 2 and the second adjustment plate 3 are both semicircular plate-shaped structures, with the multiple first connection holes 21 in each group being equidistant from the center of the first adjustment plate 2. The line connecting the centers of the first adjustment plate 2 and the second adjustment plate 3 is perpendicular to the axis of the connecting rod 5. The bottom edges of the first adjustment plate 2 and the second adjustment plate 3 are respectively connected to the sides of the bed frame. The curved edges of the first adjustment plate 2 and the second adjustment plate 3 are positioned above the bed surface. The curved structure reduces the probability of collision. Specifically, two curved pads 22 are provided on the side of the first adjustment plate 2 facing the second adjustment plate. The two curved pads 22 are positioned along the edges of the first adjustment plate 2 to reduce collisions. The curved shape of the first and second adjustment plates 2 and 3 also enhances the support strength of the connecting rod. The radius of the first adjustment plate 2 can be at least twice the radius of the second adjustment plate 3. The diameter of the first adjustment plate 2 is at least 3 / 5 of the length of the bed frame 1.

[0043] The multiple second connection holes 31 are equidistant from the center of the second adjustment plate 3 and are arranged along the edge of the second adjustment plate 3. The first fulcrum 41 of the telescopic support rod 4 is rotatably connected to the center of the second adjustment plate 3. The distance between the first fulcrum 41 and the second fulcrum 42 of the telescopic support rod 4 is equal to the distance between the second connection holes 31 and the center of the second adjustment plate 3.

[0044] As a preferred embodiment, Figure 4 As shown, the connecting rod 5 comprises a first outer tube 53, a first inner rod 54, and a first handle 52. A radially extending fixing plate 55 is disposed within each end of the first outer tube 53. A first fixing block 56 is disposed at each end of the first outer tube 53. The first inner rod 54 passes through the fixing plates 55 and the first fixing block 56. The first handle 52 is connected to the end of the first inner rod 54 closest to the telescopic support rod 4, while the end of the first outer tube 53 closest to the first handle 52 is connected to the telescopic support rod 4.

[0045] A first elastic member 57 is sleeved on the first inner rod 54 at one end near the first handle 52. The first elastic member 57 is disposed inside the first outer tube 53, with one end abutting the fixing plate 55 and the other end abutting the first fixing block 56. Pulling the first handle 52 causes the end of the first inner rod 54 near the first adjustment plate 2 to retract into the first outer tube 53, thereby adjusting the position of the connecting rod 5.

[0046] When the first handle 52 is released, the end of the first inner rod 54 close to the first adjustment plate 2 extends out of the first outer tube 53 and is inserted into the first connecting hole 21 to connect the connecting rod 5 to the first adjustment plate 2 .

[0047] In this embodiment, the connection state between the connecting rod 5 and the first adjustment plate 2 can be adjusted by pulling the first handle 52 , so that the installation position and height of the connecting rod 5 can be easily adjusted.

[0048] A grip 51 is provided on the upper side of the connecting rod 5. The grip 51 and the connecting rod 5 are both cylindrical structures. The axis of the grip 51 is perpendicular to the axis of the connecting rod 5, and the grip 51 can be conveniently held.

[0050] As a preferred embodiment, Figure 5 As shown, the telescopic support rod 4 includes an inner sleeve 47 and an outer sleeve 46. The inner sleeve 47 is inserted into the inner side of the outer sleeve 46. The inner sleeve 47 is provided with a plurality of third connecting holes 471 distributed along its length. A second elastic connector 45 is provided at the upper end of the outer sleeve 46 and connected to the inner sleeve 47 by inserting the second elastic connector into the third connecting holes 471. To adjust the length of the telescopic support rod 4, the inner sleeve 47 is moved relative to the outer sleeve 46, and the second elastic connector is inserted into the corresponding third connecting hole 471, thereby adjusting the length of the telescopic support rod 4.

[0051] As a preferred embodiment, Figure 5 As shown, the first elastic connector 44 and the second elastic connector 45 each include a second outer tube 441, a second inner rod 442, and a second handle 443.

The second handle 443 is connected to one end of the second inner rod 442, and a second elastic member 445 is sleeved on the second inner rod 442. The second elastic member 445 is provided inside the second outer tube 441 and its two ends are respectively abutted against the two second fixing blocks. The second outer tube 441 is perpendicularly connected to the outer sleeve 46, that is, the axis of the second outer tube 441 is perpendicular to the center line of the outer sleeve 46.

[0052] Specifically, the first elastic member and the second elastic member are springs of different specifications.

[0053] When the second handle 443 is pulled, the end of the second inner rod 442 close to the second adjustment plate 3 can be retracted into the second outer tube 441. When the second handle 443 is released, the second inner rod 442 extends out of the second outer tube 441, and the second inner rod 442 is inserted into the second connecting hole 31 or the third connecting hole 471.

[0054] The second outer tube 441 of the second elastic connector 45 is disposed outside the outer sleeve 46 , and the second inner insert rod 442 thereof is inserted into the third connecting hole 471 , thereby connecting the outer sleeve with the inner sleeve.

[0055] The second outer tube 441 of the first elastic connector 44 extends from one side of the outer sleeve 46 to the inner side of the outer sleeve 46 and is connected to the inner wall on the opposite side, and its second inner insert rod 442 can extend out of the side wall on the opposite side of the outer sleeve 46 and be inserted into the second connecting hole 31, thereby connecting the outer sleeve to the second adjustment plate.

[0056] The provision of the second elastic connector 45 and the first elastic connector 44 makes it easier to adjust the rotation angle and telescopic length of the telescopic support rod 4 and improves the adjustment efficiency.
