Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a foldable high and low pull dumbbell rowing machine. Background Technology

[0002] The dumbbell rowing machine is a fitness equipment that combines the functions of dumbbells and rowing machines. The high and low pull dumbbell rowing machine allows users to choose between high or low pulls to exercise different muscle groups according to their needs.

[0003] For example, the utility model patent with authorization announcement number CN219558611U discloses a high and low pull dumbbell rowing machine that can perform both high and low rowing modes, allowing exercisers to choose different exercise modes according to their own exercise needs, making exercise more convenient for exercisers.

[0004] In existing technology, when the exerciser pulls the handles to raise and lower the dumbbell rack, the handles rely entirely on the exerciser's grip for stability. Therefore, if the exerciser's hand slips during the exercise, the dumbbell rack will fall from a high position. This not only shortens the lifespan of the high and low dumbbell rowing machine, but also causes the handles to reset, requiring the exerciser to get off the seat and pick up the handles again, thus affecting exercise efficiency.

[0005] Therefore, it is necessary to invent a foldable high and low pull dumbbell rowing machine to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a foldable high and low dumbbell rowing machine that prevents the dumbbell rack from falling off due to the user slipping from the handle during high and low pull exercises, thus ensuring the lifespan of the equipment. Furthermore, it eliminates the need for the user to get up and retrieve the handles, improving exercise efficiency. This addresses the problem mentioned in the background art where, when the user pulls the handles to raise and lower the dumbbell rack, the rack, which relies entirely on the user's grip, can slip during exercise, causing it to fall from a higher position. This not only shortens the lifespan of the high and low pull dumbbell rowing machine but also forces the handles to reset, requiring the user to get off the seat and retrieve the handles again, thus affecting exercise efficiency.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a foldable high and low pull dumbbell rowing machine, comprising:

[0008] A foldable bracket is used to install the sliding support mechanism and the dumbbell height-lowering mechanism;

[0009] A sliding support mechanism for supporting the buttocks of an exerciser;

[0010] A dumbbell pull-up mechanism, wherein the dumbbell pull-up mechanism is used for performing pull-up exercises; and

[0011] Two sets of handle assemblies, each set including a middle rod fixedly connected to the adjacent steel cable in the dumbbell high and low pull mechanism, with grip rods fixedly installed at both ends of the middle rod. An annular groove is opened on the outer side of the grip rod near the middle rod, and a storage groove communicating with the annular groove is opened on the right side of the grip rod. An elastic collar is sleeved on the inner side of the annular groove, and an elastic wristband stored in the storage groove is fixedly connected to the side of the elastic collar. A grip sleeve is sleeved on the outer side of the grip rod, and threads are provided on both the outer side of the grip rod and the inner side of the grip sleeve. The grip rod and the grip sleeve are threadedly connected.

[0012] According to at least one embodiment of the present disclosure, a foldable high and low pull dumbbell rowing machine includes an inverted Y-shaped support, a connecting support is fixedly disposed on the bottom right side of the inverted Y-shaped support, and a support support is rotatably connected to the inner side of the connecting support via a pin.

[0013] According to at least one embodiment of the present disclosure, a foldable high and low pull dumbbell rowing machine has a locking pin slidably provided through the front of the connecting bracket, the locking pin passing through the supporting bracket and slidably connected to the supporting bracket.

[0014] According to at least one embodiment of the present disclosure, a foldable high and low pull dumbbell rowing machine includes a sliding support mechanism comprising an inverted U-shaped frame slidably sleeved on the outside of a support bracket. The top and bottom inner sides of the inverted U-shaped frame are rotatably provided with four concave wheels via pins, and the concave wheels are all slidably sleeved on the outside of the support bracket.

[0015] According to at least one embodiment of the present disclosure, a foldable high and low pull dumbbell rowing machine has a seat cushion fixedly disposed on the top of the inverted U-shaped frame, and a locking bolt threadedly connected to the concave wheel is disposed through the front of the concave wheel.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features a handle assembly. Before starting a workout, the grip sleeve is rotated counterclockwise to release the obstruction between the annular groove and the storage groove. The elastic wristband is then removed from the storage groove and placed on the wrist. The grip sleeve is then rotated clockwise until it engages with the elastic ring. Pulling the grip sleeve then causes it to pull the intermediate rod via the grip rod, traction on the steel cable in the dumbbell pull-up mechanism, enabling high or low pull exercises. If the exerciser slips and releases the grip sleeve, the elastic wristband on the outside of the wrist and the elastic ring on the inside of the annular groove can still pull the intermediate rod via the grip rod, preventing the intermediate rod from causing the dumbbell holder to fall due to the steel cable. Compared to existing technologies, this invention prevents the dumbbell holder from falling during high and low pull exercises due to the grip sleeve slipping out of the hand, ensuring the equipment's lifespan. Furthermore, it eliminates the need for the exerciser to get up and retrieve the handle, improving workout efficiency. Attached Figure Description

[0028] Figure 1 This is a schematic diagram of the overall structure of a foldable high and low pull dumbbell rowing machine according to one embodiment of the present disclosure.

[0029] Figure 2 This is a schematic diagram of the foldable support 1 and sliding support mechanism 2 of a foldable high and low dumbbell rowing machine according to one embodiment of the present disclosure.

[0030] Figure 3 This is a schematic diagram of the handle assembly 4 of a foldable high and low pull dumbbell rowing machine according to one embodiment of the present disclosure.

[0031] like Figures 1-3 As shown, the foldable high and low pull dumbbell rowing machine disclosed herein may include: a foldable support frame 1, a sliding support mechanism 2, a dumbbell high and low pull mechanism 3, and two sets of handle assemblies 4, etc.

[0032] It should be noted that the dumbbell high and low pull mechanism 3 is a solution already disclosed in the prior art and a necessary technical feature for solving the technical problem using this application. Therefore, this application will not elaborate on the specific structure of the dumbbell high and low pull mechanism 3 here.

[0033] like Figure 1 and Figure 2 As shown in this disclosure, the foldable bracket 1 includes an inverted Y-shaped bracket 11. A connecting bracket 12 is fixedly provided at the bottom right side of the inverted Y-shaped bracket 11. A supporting bracket 13 is rotatably connected to the inner side of the connecting bracket 12 via a pin. A locking pin 14 is slidably provided through the front of the connecting bracket 12. The locking pin 14 passes through the supporting bracket 13 and is slidably connected to the supporting bracket 13.

[0034] Therefore, after the exercise is completed, the locking pin 14 can be pulled forward until the locking pin 14 releases the lock between the connecting bracket 12 and the supporting bracket 13. Then, the supporting bracket 13 is rotated counterclockwise around the pin to complete the folding and storage of the supporting bracket 13. Then, the locking pin 14 is reinserted into the connecting bracket 12. At this time, the locking pin 14 limits the supporting bracket 13 from the right side to prevent the supporting bracket 13 from accidentally resetting.

[0035] like Figure 2 As shown, in a preferred embodiment, the sliding support mechanism 2 includes an inverted U-shaped frame 21 that is slidably sleeved on the outside of the support bracket 13. The top and bottom inner sides of the inverted U-shaped frame 21 are rotatably provided with four concave wheels 22 via pins. The concave wheels 22 are all slidably sleeved on the outside of the support bracket 13. A seat cushion 23 is fixedly provided on the top of the inverted U-shaped frame 21. A locking bolt 24 that is threadedly connected to the concave wheel 22 is provided through the front of the concave wheel 22.

[0036] Therefore, when the exerciser sits on top of the seat cushion 23 and steps on the pedal on the inverted Y-shaped support 11, he can move the seat cushion 23 to the right along the support support 13 by straightening his legs. During this process, the four concave wheels 22 continuously roll on the outside of the support support 13, thus cooperating with the inverted U-shaped frame 21 to support the seat cushion 23 as it moves.

[0037] like Figure 3 As shown in this disclosure, any one of the handle assemblies 4 includes an intermediate rod 41 fixedly connected to the adjacent steel rope in the dumbbell high and low pull mechanism 3. Both ends of the intermediate rod 41 are fixedly provided with grip rods 42. An annular groove 43 is opened on the outer side of the grip rod 42 near the intermediate rod 41. A storage groove 44 communicating with the annular groove 43 is opened on the right side of the grip rod 42. An elastic collar 45 is sleeved on the inner side of the annular groove 43. An elastic wristband 46 stored in the storage groove 44 is fixedly connected to the side of the elastic collar 45. A grip sleeve 47 is sleeved on the outer side of the grip rod 42. Threads are provided on the outer side of the grip rod 42 and the inner side of the grip sleeve 47. The grip rod 42 and the grip sleeve 47 are threaded together.

[0038] Therefore, before starting the exercise, rotate the grip sleeve 47 counterclockwise to release the obstruction between the annular groove 43 and the storage groove 44. Then, take out the elastic wristband 46 from the inside of the storage groove 44 and put it on your wrist. Then, rotate the grip sleeve 47 clockwise until the grip sleeve 47 presses against the connecting part of the elastic collar 45. At this point, by pulling the grip sleeve 47, the grip sleeve 47 drives the intermediate rod 41 through the grip rod 42 to pull the steel cable in the dumbbell high and low pull mechanism 3, so as to achieve high pull or low pull. During exercise, when the exerciser slips and releases their grip on the sleeve 47, the elastic wristband 46, which is fitted onto the outside of the exerciser's wrist, and the elastic collar 45, which is fitted onto the inside of the annular groove 43, can pull the intermediate bar 41 through the grip bar 42. This prevents the intermediate bar 41 from causing the dumbbell mounting frame to fall due to the steel cable. Compared with existing technologies, this can prevent the dumbbell mounting frame from falling due to the slip of the grip on the sleeve 47 during pull-ups, thus ensuring the service life of the equipment. At the same time, it eliminates the need for the exerciser to get up and pick up the handle again, improving exercise efficiency.

[0039] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0040] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
