[0002] A fitness frame is a type of exercise equipment that allows users to hang resistance bands. Existing fitness frames typically use a frame structure, often L-shaped, with hooks on the frame for hanging resistance bands. Users can easily perform stretching exercises in different positions by attaching the resistance bands to the hooks at different locations. However, existing fitness frames are not foldable, resulting in large storage space and difficulties in transporting them. Utility Model Content

[0003] The purpose of this invention is to provide a multifunctional fitness rack with a linkage support structure to solve the problems of existing fitness racks being non-foldable, having large storage space, and being difficult to transport.

[0004] This utility model is achieved through the following technical solution:

[0005] A multifunctional fitness frame with a linkage support structure includes a base frame and an upright frame rotatably connected to the base frame. The upright frame can rotate between a folded position and an unfolded position with its connection point with the base frame as the axis. A support rod assembly that can be folded or unfolded is provided between the base frame and the upright frame. When the upright frame is switched to the unfolded position, the support rod assembly unfolds to restrict the upright frame to the unfolded position. When the upright frame is switched to the folded position, the support rod assembly folds up.

[0006] Furthermore, the support rod assembly includes several support rods that can rotate relative to each other. When the upright is switched to the unfolded position, the several support rods rotate relative to each other and unfold to form a triangular fixed structure with the base frame and the upright. When the upright is switched to the folded position, the several support rods rotate and fold between the base frame and the upright.

[0007] Furthermore, the support rods include an upper support rod and a lower support rod. One end of the upper support rod is rotatably connected to the upright frame, and the other end is rotatably connected to the lower support rod. The end of the lower support rod away from the upper support rod is rotatably connected to the base frame. The upright frame is provided with a stop block on one side of the upper support rod. The direction from the unfolded position to the folded position is defined as the folding direction. When the upright frame is rotated to the unfolded position, the upper support rod abuts against the stop block to restrict the upper support rod from rotating relative to the lower support rod in the folding direction.

[0008] Furthermore, the stop block is provided with a stop groove for inserting the upper support rod.

[0009] Furthermore, the stop block is cylindrical, and the stop groove extends circumferentially around the stop block.

[0010] Furthermore, the direction from the folded position to the unfolded position is defined as the unfolding direction. The base frame is provided with a stop block. When the upright frame is rotated to the unfolded position, the stop block abuts against the upright frame to restrict the upright frame from rotating in the unfolding direction.

[0011] Furthermore, the stop block is provided with a stop groove for the stand to be inserted when it is rotated to the unfolded position.

[0012] Furthermore, when the upright is rotated to the folded position, the upright is attached to the base frame; when the upright is rotated to the unfolded position, the upright is perpendicular to the base frame.

[0013] Furthermore, the base frame has a folding groove for the upright to be inserted when the upright is rotated to the folding position, and when the upright is inserted into the folding groove, a folding space is formed between the upright and the groove wall of the folding groove for the support rod assembly to be inserted.

[0014] Furthermore, the base frame is provided with a number of spaced-apart lower hanging parts; and / or the upright frame is provided with a number of spaced-apart upper hanging parts; and / or the base frame is provided with a pulley at the end where it is rotatably connected to the upright frame.

[0015] The advantage of this technical solution is that by configuring the fitness frame as a base frame and an upright frame that can rotate relative to the base frame to a folded position and an unfolded position, and by configuring a support rod assembly between the upright frame and the base frame, the support rod assembly unfolds when the upright frame is switched to the unfolded position to restrict the upright frame to the unfolded position, and folds up when the upright frame is switched to the folded position, the fitness frame can be folded and stored, which is convenient for storage and transportation. At the same time, it makes the fitness frame have good stability when unfolded. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figure 1-5 As shown, the multifunctional fitness frame with a linkage support structure includes a base frame 1 and an upright frame 2 rotatably connected to the base frame 1. The upright frame 2 can rotate between a folded position and an unfolded position with its connection point with the base frame 1 as the axis. A support rod group 3 that can be folded or unfolded is provided between the base frame 1 and the upright frame 2. When the upright frame 2 is switched to the unfolded position, the support rod group 3 unfolds to restrict the upright frame 2 to the unfolded position. When the upright frame 2 is switched to the folded position, the support rod group 3 folds up. This embodiment provides a multifunctional fitness frame with a linkage support structure to solve the problems of existing fitness frames being non-foldable, having large storage space, and being difficult to transport. It mainly involves configuring the fitness frame as a base frame 1 and an upright frame 2 that can rotate relative to the base frame 1 to a folded position and an unfolded position. A support rod assembly 3 is arranged between the upright frame 2 and the base frame 1. The support rod assembly 3 unfolds when the upright frame 2 is switched to the unfolded position to restrict the upright frame 2 to the unfolded position, and folds up when the upright frame 2 is switched to the folded position, so that the fitness frame can be folded and stored, which is convenient for storage and transportation. At the same time, it makes the fitness frame have good stability when unfolded.

[0025] In this embodiment of the invention, the support rod assembly 3 includes several support rods 301 that can rotate relative to each other. When the upright frame 2 is switched to the unfolded position, the support rods 301 rotate relative to each other and unfold to form a triangular fixing structure with the base frame 1 and the upright frame 2. When the upright frame 2 is switched to the folded position, the support rods 301 rotate relative to each other and fold between the base frame 1 and the upright frame 2. This configuration, by arranging the support rod assembly 3 into several support rods 301, which rotate relative to each other and unfold to form a triangular fixing structure with the base frame 1 and the upright frame 2 when the upright frame 2 is switched to the folded position, provides good stability when the fitness frame is unfolded. Simultaneously, when the upright frame 2 is switched to the folded position and folds relative to each other between the base frame 1 and the upright frame 2, the fitness frame has a good folding and storage effect and a small storage volume.

[0026] In this embodiment of the invention, the plurality of support rods 301 include an upper support rod 302 and a lower support rod 303. One end of the upper support rod 302 is rotatably connected to the upright 2, and the other end is rotatably connected to the lower support rod 303. The end of the lower support rod 303 away from the upper support rod 302 is rotatably connected to the base frame 1. The upright 2 is provided with a stop block 201 on one side of the upper support rod 302. The direction from the unfolded position to the folded position is defined as the folding direction, and the direction from the folded position to the unfolded position is defined as the unfolding direction. When the upright 2 is rotated to the unfolded position, the upper support rod 302 abuts against the stop block 201, restricting the upper support rod 302 from rotating relative to the lower support rod 303 in the folding direction. By configuring the plurality of support rods 301 as an upper support rod 302 and a lower support rod 303, and providing a stop block 201 on one side of the upper support rod 302 to restrict the upper support rod 302 from rotating relative to the lower support rod 303 in the folding direction, the above arrangement provides good stability when the upright 2 is rotated to the unfolded position.

[0027] It should be noted that when the upright frame 2 is rotated to the unfolded position, the upper support rod 302 and the lower support rod 303 unfold together to form a triangular fixed structure with the base frame 1 and the upright frame 2. At this time, the upper support rod 302 and the lower support rod 303 are in a locked state. When the user hangs the tension rope on the upright frame 2 and pulls it forward, the upper support rod 302 has a tendency to rotate in the folding direction. However, since the upper support rod 302 abuts against the stop block 201, it restricts the upper support rod 302 from rotating relative to the lower support rod 303 in the folding direction, preventing the upper support rod 302 and the lower support rod 303 from rotating and unlocking in the folding direction, so that the upright frame 2 has good stability when it is rotated to the unfolded position. When the fitness frame needs to be folded and stored, simply apply an upward force at the connection between the upper support rod 302 and the lower support rod 303 to make the upper support rod 302 rotate and unlock relative to the lower support rod 303 in the unfolding direction, so that several support rods 301 can rotate and fold with the upright frame 2.

[0028] In this embodiment of the invention, the stop block 201 is provided with a stop groove 202 for inserting the upper support rod 302. The above-mentioned arrangement, by configuring the stop groove 202 for inserting the upper support rod 302 on the stop block 201, makes the upper support rod 302 stable and less prone to displacement when it abuts against the stop block 201.

[0029] In this embodiment of the invention, the stop block 201 is cylindrical, and the stop groove 202 extends circumferentially around the stop block 201. By configuring the stop block 201 as cylindrical and the stop groove 202 as extending circumferentially around the stop block 201, the upper support rod 302 is stable and not easily deviated when it abuts against the stop block 201.

[0030] In this embodiment of the invention, a stop block 101 is provided on the base frame 1. When the upright frame 2 is rotated to the unfolded position, the stop block 101 abuts against the upright frame 2, restricting the upright frame 2 from rotating in the unfolding direction. The above arrangement, by configuring the stop block 101 on the base frame 1 to abut against the upright frame 2 and restrict the upright frame 2 from rotating in the unfolding direction when it is rotated to the unfolded position, provides good stability for the upright frame 2 when it is rotated to the unfolded position.

[0031] In this embodiment of the invention, the stop block 101 is provided with a stop groove 102 for the stand 2 to be inserted when it is rotated to the unfolded position. The above-mentioned arrangement, by configuring the stop groove 102 on the stop block 101 for the stand 2 to be inserted when it is rotated to the unfolded position, makes the stand 2 have good stability when it is rotated to the unfolded position.

[0032] In this embodiment of the invention, when the upright frame 2 is rotated to the folded position, it rests against the base frame 1. When the upright frame 2 is rotated to the unfolded position, it is perpendicular to the base frame 1. When the support rod assembly 3 is unfolded and forms a triangular structure with the upright frame 2 and the base frame 1, the angle α between the support rod assembly 3 and the base frame 1 ranges from 55° to 65°, and the angle β between the support rod assembly 3 and the upright frame 2 ranges from 25° to 35°. This configuration ensures good stability for the upright frame 2 when it is rotated to the unfolded position.

[0033] In this embodiment of the invention, the base frame 1 has a folding groove 103 for the upright frame 2 to be inserted when it is rotated to the folding position. When the upright frame 2 is inserted into the folding groove 103, a folding space 104 for the support rod assembly 3 is formed between the upright frame 2 and the groove wall of the folding groove 103. This arrangement, by configuring the folding groove 103 on the base frame 1 for the upright frame 2 to be inserted, and by configuring the folding groove 103 such that a folding space 104 for the support rod assembly 3 is formed between the upright frame 2 and the groove wall of the folding groove 103 when it is inserted, ensures that the upright frame 2 has a good folding and storage effect when it is rotated to the folding position, resulting in a small storage volume.

[0034] In this embodiment of the invention, the base frame 1 is provided with several spaced-apart lower hanging parts 105, and the upright frame 2 is provided with several spaced-apart upper hanging parts 200. This arrangement, by configuring the lower hanging parts 105 on the base frame 1 and the upper hanging parts 200 on the upright frame 2, facilitates the user in hanging the resistance band at different positions on the fitness frame.

[0035] In this embodiment of the invention, a pulley 106 is provided at the end of the base frame 1 that is rotatably connected to the upright frame 2. This arrangement, by providing the pulley 106 at the end of the base frame 1 that is rotatably connected to the upright frame 2, facilitates the movement of the fitness frame after it is folded and stored.

[0036] In this embodiment of the invention, the base frame 1 is rotatably connected to the upright frame 2 via the stop block 101. A hook 108 is provided at the end of the base frame 1 away from the stop block 101, and a hanging ring 204 is provided on the upright frame 2 to engage with the hook 108. This arrangement, by configuring the hook 108 on the base frame 1 and the hanging ring 204 on the upright frame 2 to engage with the hook 108, facilitates fixing the upright frame 2 to the base frame 1 after the fitness frame is folded and stored.
