Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to an easy-folding 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. With its continuous development, existing technologies have produced dumbbell rowing machines that can perform both high and low dumbbell pulls.

[0003] To reduce the space occupied when not in use and facilitate storage, most existing high and low pull dumbbell rowing machines have a folding function. To fold them, first pull out the ball pin on the rotating seat that is used to lock the slide rail, then lift the slide rail connected to the ground tube on the right side of the rotating seat until the slide rail rotates to a vertical position, and then reset the ball pin to complete the folding operation.

[0004] However, in actual folding, the ball pin is usually located at one end of the slide rail. In order to make the slide rail rotation easier, after unlocking, it is often necessary to walk to the other end of the slide rail and then lift and rotate the slide rail. This means that a squatting posture is required when disassembling and assembling the ball pin, and a standing posture is required when lifting and rotating the slide rail. Therefore, during the folding process, it is necessary to first squat to remove the ball pin, then stand up and move to the other end of the slide rail to lift and rotate it, and then switch back to a squatting posture to insert the ball pin. The operation is too cumbersome and inconvenient in actual use.

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

[0006] The purpose of this invention is to provide an easy-to-fold high and low pull dumbbell rowing machine that eliminates the need for multiple standing and squatting movements during folding and unfolding, reducing the difficulty of folding and unfolding and making it more convenient in actual use. This solves the problem mentioned in the background art, where a squatting posture is required when assembling and disassembling the ball pin, and a squatting posture is required to switch to a standing posture when raising and rotating the slide rail. Therefore, during the folding process, it is necessary to first squat to remove the ball pin, then stand up and move to the other end of the slide rail to lift and rotate it, and then switch back to a squatting posture to insert the ball pin. This operation is too cumbersome and inconvenient in actual use.

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

[0008] The main body of the dumbbell rowing machine;

[0009] A slide rail assembly for mounting a hip support assembly and a locking folding mechanism;

[0010] A hip support assembly for supporting the hips of an exerciser; and

[0011] The locking folding mechanism includes a sliding channel inside the slide rail and a sliding groove on the top of the slide rail and connected to the sliding channel. A locking rod is slidably disposed inside the sliding channel. An adjusting rod is fixedly disposed on the top right side of the locking rod and slidably disposed inside the sliding groove. A clearance groove for avoiding the pin is provided on the left end of the locking rod. The locking folding mechanism also includes a stop block fixedly disposed on the top of the slide rail and adjacent to the adjusting rod. The locking folding mechanism also includes a transverse locking groove inside the rotating seat and a longitudinal locking hole penetrating the bottom of the rotating seat.

[0012] According to at least one embodiment of the present disclosure, the foldable high and low pull dumbbell rowing machine includes a slide rail assembly comprising a rotating seat fixedly disposed on the bottom right side of the dumbbell rowing machine body, wherein the right side inside the rotating seat is rotatably connected to the slide rail 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 ground-contact tube fixedly connected to the right end of the slide rail, and a plurality of locking openings are provided on the front of the slide rail.

[0014] According to at least one embodiment of the present disclosure, the foldable high and low dumbbell rowing machine includes a hip support assembly comprising a sliding frame sleeved on the outside of a slide rail, wherein each of the four inner corners of the sliding frame is rotatably connected to a concave wheel via a pin, and any one of the concave wheels is rotatably sleeved on the outside of the slide rail.

[0015] According to at least one embodiment of the present disclosure, a foldable high and low pull dumbbell rowing machine has a support fixedly provided on the top of the sliding frame, and a locking bolt that is threadedly connected to the sliding frame and adapted to the locking opening is provided through the front of the sliding frame.

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

[0017] This invention features a locking folding mechanism. When folding the slide rail assembly, the user can squat down near the right end of the slide rail, then move the adjusting rod to the right. This causes the left end of the locking rod to disengage from the transverse locking groove. The user then gradually stands up, lifting the right end of the slide rail until it is rotated to a vertical position. At this point, the locking rod moves down along the sliding channel under gravity and actively inserts into the longitudinal locking hole to achieve a limit. Compared to existing technologies, this invention eliminates the need for multiple standing and squatting movements during folding and unfolding, reducing the difficulty of folding and unfolding and making it more convenient in actual use.

[0031] Figure 3 This is a schematic diagram of the locking folding mechanism 4 of an easy-to-fold high and low dumbbell rowing machine according to one embodiment of the present disclosure.

[0032] Figure 4 This is a schematic diagram of the slide rail assembly 2 of an easily foldable high and low dumbbell rowing machine according to one embodiment of the present disclosure after folding.

[0033] like Figures 1-4 As shown, the foldable high and low dumbbell rowing machine disclosed herein may include: dumbbell rowing machine body 1, slide rail assembly 2, hip support assembly 3, and locking folding mechanism 4, etc.

[0034] like Figure 1 and Figure 2 As shown in this disclosure, the slide rail assembly 2 includes a rotating seat 21 fixedly installed at the bottom right side of the dumbbell rowing machine body 1. The right side of the rotating seat 21 is rotatably connected to the slide rail 22 via a pin. The right end of the slide rail 22 is fixedly connected to a ground-contact tube 23. The front of the slide rail 22 has multiple locking openings 24.

[0035] It should be noted that the dumbbell rowing machine body 1 and slide rail assembly 2 mentioned above are both solutions already disclosed in the prior art, and are not essential technical features for solving the technical problem of this application. Therefore, this application will not elaborate on their specific structure and working process here.

[0036] like Figure 1 As shown, in a preferred embodiment, the hip support assembly 3 includes a sliding frame 31 sleeved on the outside of the slide rail 22. Each of the four corners of the inner side of the sliding frame 31 is rotatably connected to a concave wheel 32 by a pin. Any one of the concave wheels 32 is rolledly sleeved on the outside of the slide rail 22. A support seat 33 is fixedly provided on the top of the sliding frame 31. A locking bolt 34 is threadedly connected to the sliding frame 31 and adapted to the locking opening 24 through the front of the sliding frame 31.

[0037] Therefore, during exercise, the exerciser sits on top of the support seat 33 with both feet on the pedals in the main body 1 of the dumbbell rowing machine, making it convenient for the exerciser to exercise in a seated position. In addition, due to the four concave wheels 32 on the inner side of the sliding frame 31, the sliding frame 31 can drive the support seat 33 to move outside the slide rail 22, thereby adjusting the position of the support seat 33 to accommodate exercisers with different leg lengths.

[0038] like Figure 2 and Figure 3 As shown, in this disclosure, the locking folding mechanism 4 includes a sliding channel 41 opened inside the slide rail 22 and a sliding groove 42 opened on the top of the slide rail 22 and connected to the sliding channel 41. A locking rod 43 is slidably disposed inside the sliding channel 41. An adjusting rod 44 is fixedly disposed on the top right side of the locking rod 43 and slidably disposed inside the sliding groove 42. A clearance groove 45 for avoiding the pin is opened at the left end of the locking rod 43. The locking folding mechanism 4 also includes a stop block 46 fixedly disposed on the top of the slide rail 22 and adjacent to the adjusting rod 44. The locking folding mechanism 4 also includes a transverse locking groove 47 opened inside the rotating seat 21 and a longitudinal locking hole 48 penetrating the bottom of the rotating seat 21.

[0039] Therefore, when folding the slide rail assembly 2, one can squat down near the right end of the slide rail 22, then move the adjusting rod 44 to the right, causing the left end of the locking rod 43 to disengage from the inside of the transverse locking groove 47. Then, one can gradually stand up, lifting the right end of the slide rail 22 until it is rotated to a vertical position. At this point, the locking rod 43 moves down along the sliding channel 41 under gravity, actively inserting into the inside of the longitudinal locking hole 48 to achieve a limit. When unfolding the slide rail assembly 2, one can move the adjusting rod 44 upwards, causing the locking rod 43 to move out of the inside of the longitudinal locking hole 48. Then, one can gradually squat down and flatten the slide rail 22, finally pushing the adjusting rod 44 to the left until it causes the locking rod 43 to insert into the transverse locking groove 47 to achieve locking. Compared to existing technologies, this method eliminates the need for multiple standing and squatting movements during folding and unfolding, reducing the difficulty of folding and unfolding and making it more convenient in actual use.

[0040] In addition, the stop block 46 can block the sliding frame 31, preventing the sliding frame 31 from excessively displacing along the slide rail 22 and accidentally touching the adjustment rod 44, thus ensuring safety during exercise.

[0041] 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.

[0042] 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.
