Description

Technical Field

[0001] The present application relates to the technical field of fitness equipment, and in particular to a push-pull rack for a strength trainer. Background Art

[0002] Current electronic strength trainers use motors or magnetic powder controllers as resistance sources and no longer require counterweights as resistance sources, thereby greatly reducing the size and weight of fitness equipment and enabling it to quickly become popular in households.

[0003] However, current electronic strength trainers have relatively simple functions, relying only on a resistance source to connect handles or rods for strength training, and are unable to provide more expanded functions. Utility Model Content

[0004] The purpose of the present application is to provide a push-pull frame for a strength training device in view of the above-mentioned problems existing in the prior art.

[0005] In order to achieve the above application purpose, the present application adopts the following technical solution: A push-pull frame for a strength trainer comprises:

[0006] An expansion base is detachably connected to the front or rear end of the pedal of the strength training device;

[0007] The high-pull bracket has a bottom that is fixedly connected to the expansion base, and a middle section or an area between the middle section and the top is provided with a plurality of adjustment holes evenly spaced in the height direction;

[0008] A connecting wire, one end of which is connected to the wire connecting block of the strength training device, and the other end of which is provided with a fastener;

[0009] The push-pull frame body has one end rotatably connected to the high-pull bracket and cooperates with the adjustment hole through a limit rod to achieve the adjustment of the rotation angle of the push-pull frame body, and a handrail is provided at the other end;

[0010] Wherein, a rope buckle which can be connected with the fastener is provided on the push-pull frame body.

[0011] Working principle and beneficial effects: 1. Compared with the prior art, when the present application is used, the expansion base is first installed at the front end or rear end of the pedal of the strength trainer. The main purpose is to be close to the position where the original handle is located, remove the handle (remove it from the pull wire connection block), and then install the high-pull bracket on the expansion base, install the connecting wire, and then connect it to the pull wire connection block and the push-pull frame of the strength trainer respectively, and the assembly is completed. The user can lie down and operate the original strength trainer using components such as a reclining stool, and can use the resistance source of the strength trainer to perform exercise operations. When the push-pull frame does not need to move, the high-pull accessory group of the present application can be removed to restore it to a strength trainer. It has the advantages of simple structure, convenient disassembly and assembly, and low cost.

[0012] 2. The push-pull frame of the present application is fixed on the high-pull bracket and can rotate up and down. The high-pull bracket is provided with an adjustment hole. The limit rod is inserted into different adjustment holes to make the push-pull frame be at different starting heights (the limit rod is used to set the starting height position of the push-pull frame and also plays a role of mechanical limit protection in the safety position) to meet training movements at different angles.

[0013] Furthermore, the high pull bracket is also provided with a top limit hole, which is located above all the adjustment holes. The top limit hole can make the push-pull frame be at the top position, so that other exercise modes (such as high pull, middle pull, single handle, rowing, etc.) can be operated to avoid interference from the push-pull frame. In this way, the push-pull frame does not need to be dismantled when used. It is only necessary to connect one end of the connecting line to the rope buckle on the push-pull frame. The user can sit or lie on the reclining stool to achieve double-arm push-ups, lying bench presses, and push-ups with the back facing the push-pull frame.

[0014] Furthermore, a gap is provided between the two handrails of the push-pull frame to avoid the top of the high-pull frame, mainly for the purpose of preventing the push-pull frame from interfering with the top of the high-pull frame when it is pushed to the uppermost position.

[0015] Furthermore, the inner side wall of the expansion base is provided with connection holes, and the front end and / or rear end side of the pedal of the strength trainer is provided with expansion holes corresponding to the connection holes, and the connection holes and the expansion holes are connected and fixed by threaded fasteners to achieve the fixation of the expansion base and the pedal of the strength trainer. The expansion base can be fixed by connecting the rear end of the front end of the pedal to the side, which does not need to occupy the space on the upper and lower surfaces of the pedal and will not affect the use of the pedal. At the same time, it is extremely convenient to disassemble and assemble, and there is no need to lift or flip the pedal, which significantly reduces the difficulty of operation. Of course, the connection method here is not limited to the above content, and it can also be a snap-on or plug-in operation, as long as it has sufficient connection strength.

[0016] Furthermore, the expansion base is provided with a plurality of mounting structures for mounting the high-pull bracket, so that the high-pull bracket can be easily mounted, and the expansion base and the high-pull bracket are arranged separately, which is also convenient for packaging and transportation.

[0017] Furthermore, a barbell bar is included, and the two ends of the barbell bar can be connected to the two armrests of the push-pull frame. The setting of the barbell bar further expands the function of the strength trainer, and the barbell bar can be lifted and removed from the push-pull frame when not in use.

[0018] Furthermore, the high-pull bracket includes a lower bracket, an upper bracket telescopically matched with the top section of the lower bracket, and a limit section connected to the side of the top section of the lower bracket, and the adjustment hole and the top limit hole are both located on the limit section. In this way, the rotation connection point between the high-pull bracket and the push-pull frame can be avoided, which facilitates the angle adjustment of the push-pull frame.

[0019] Furthermore, the limiting section includes two upper and lower curved sections and a vertical section arranged between the two curved sections, the two curved sections are fixedly connected to the side of the lower bracket, the top limiting hole is located on the upper curved section, and the adjustment holes are evenly spaced along the length direction of the vertical section. In this way, not only the structural strength of the limiting section is ensured, but also the positions of the adjustment holes and the top limiting hole can be significantly distinguished.

[0020] Furthermore, a fixed pulley and a pull rod are provided on the top of the high pull bracket, and the connecting wire can cooperate with the fixed pulley to connect the pull rod. In this way, when the push-pull bracket is not in use, the connecting wire can be passed around the fixed pulley to connect the pull rod, thereby realizing the high pull action, further expanding the sports function of the strength trainer.

[0021] Furthermore, it also includes a reclining stool, which is arranged on the pedal of the strength training device and is detachably connected to the pedal. Different from ordinary stools, the reclining stool of the present application can not only be used as a component for lying or sitting, but can also be connected to the pedal to prevent displacement, thereby preventing the reclining stool from moving and causing danger when the user uses it.

[0022] Furthermore, it also includes a sliding sleeve, which is installed on the high-pull bracket and can be adjusted in position in the height direction of the high-pull bracket. The sliding sleeve is provided with a wiring hole for the connecting wire and the pull wire of the strength trainer to pass through, and the wiring hole is provided with a rolling pulley on the side facing the pedal. In this way, when the push-pull frame and the high-pull bracket are not used, the connecting wire or the pull wire of the strength trainer can be passed through the wiring hole of the sliding sleeve and matched with the rolling pulley, and then the pull rod and other components can be installed to realize the operation of the middle pull, and with the effect of the adjustable position of the sliding sleeve, various actions can be realized, further expanding the training actions of the strength trainer.

[0023] Furthermore, two auxiliary support rods are provided on one side of the high-pull bracket close to the pedal, and the two auxiliary support rods can limit the push-pull bracket body, thus achieving a secondary limit effect, thereby preventing the push-pull bracket body from being hit by the user in the event of a user's mistake.
