Description

Technical Field

[0001] This utility model relates to the field of training equipment technology, and in particular to a pull-back muscle training device for training. Background Technology

[0002] Back muscle training is crucial for strengthening back muscles and improving posture. Common back muscle training methods include barbell rows and pull-ups. Among existing back muscle training equipment, common devices include traditional resistance bands and barbell rowing machines. While these devices can meet basic back muscle training needs, they have some problems in practical use: traditional resistance bands, due to limitations in structural design or transmission components, are prone to jerking or uneven movement, affecting the trainee's experience and training results; furthermore, some training equipment generates significant impact when lowering the weights, which may damage the ground and shorten the equipment's lifespan. Utility Model Content

[0003] This application provides a back muscle training device for training. Through the up-and-down swing of the swing arm and the action of the counterweight, the trainee can feel continuous changes in movement during the training process. Unlike some traditional equipment, which may experience jamming or unevenness, this device helps to improve the comfort and effectiveness of training. The use of a spring tube can effectively reduce the impact force when the swing component is lowered, avoiding damage to the ground and extending the service life of the equipment.

[0004] This application provides a pull-back muscle trainer for training, including,

[0005] A support plate with a mounting plate fixedly connected to its upper side; the support plate can be fixed to the wall panel with bolts.

[0006] The tensioning assembly is installed on the lower side of the mounting plate. The tensioning assembly includes pulley one, pulley two, and a steel wire rope. Pulley one and pulley two are both fixedly connected to the lower side of the mounting plate and are arranged side by side. The steel wire rope is slidably connected to the grooves on pulley one and pulley two. One end of the steel wire rope is tied to a handle, and a rubber sleeve can be wrapped around the handle to facilitate the trainee's grip. The other end of the steel wire rope is fixedly connected to a connecting block.

[0007] The swing assembly is installed on the front side of the support plate. The swing assembly is driven by the tensioning assembly to move, thereby realizing the back muscle tension training of the trainee. There are two sets of both the swing assembly and the tensioning assembly. The swing assembly includes a mounting base, a swing rod and a support base. The mounting base is fixedly connected to the front side of the support plate by bolts. Mounting block one is fixedly connected to the rear side of the swing rod. Mounting block one is rotatably connected to the mounting base through a rotating shaft one. Mounting block two is fixedly connected to the front side of the swing rod. A connecting rod is fixedly connected to the front side of mounting block two. The support base is fixedly connected to the front side of the connecting rod. Two parallel mounting rods are fixedly connected to the upper side of the support base.

[0008] The buffer assembly, located below the swing assembly, reduces the impact force of the swing assembly when it is lowered to the ground, thus mitigating damage to the ground. The buffer assembly includes a base plate and a spring tube. The base plate can be fixed to the ground with bolts. When no counterweight is placed on the support base, the base plate is located below the support base and remains horizontal with it. The spring tube is fixedly connected to the upper side of the base plate, and its upper end is fixedly connected to the lower side of the support base. The spring tube is made of a steel spring that can withstand a certain weight.

[0009] Further mounting block two is located on one side of the connecting block, and the two are rotatably connected by rotating shaft two.

[0010] The swing arm and connecting rod are all made of solid stainless steel.

[0011] A fixing rod is also fixedly connected to the front side of the support plate, which is located between the two swing components. A U-shaped base is slidably fitted on the fixing rod, and a seat plate is fixedly connected to the upper side of the U-shaped base. The U-shaped base can be fixed to the fixing rod with bolts.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: through the up-and-down swing of the swing arm and the action of the counterweight, the trainee can feel continuous movement changes during the training process, unlike some traditional equipment that may experience jamming or unevenness, which helps to improve the comfort and effectiveness of training; the use of the spring tube can effectively reduce the impact force when the swing component is lowered, avoid damage to the ground, and extend the service life of the equipment.

[0022] Example 1

[0023] Please see Figure 1-5 A pullback muscle trainer for training, comprising:

[0024] Support plate 10, with mounting plate 14 fixedly connected to the upper side of support plate 10, support plate 10 can be fixed to wall panel by bolts;

[0025] The tensioning assembly is installed on the lower side of the mounting plate 14;

[0026] The swing component is installed on the front side of the support plate 10. The swing component is driven to move by the pulling of the tension component, thereby realizing the back muscle tension training of the trainee.

[0027] The buffer component, located below the swing assembly, can reduce the impact force when the swing assembly is lowered onto the ground, thus mitigating damage to the ground.

[0028] The tensioning assembly includes pulley 31, pulley 32, and wire rope 33;

[0029] Pulley 1 31 and pulley 2 32 are both fixedly connected to the lower side of the mounting plate 14, with pulley 1 31 and pulley 2 32 arranged side by side; wire rope 33 is slidably connected to the grooves on pulley 1 31 and pulley 2 32, with a handle 30 attached to one end of the wire rope 33, and a rubber sleeve can be wrapped around the handle 30 to facilitate the trainee's grip on the handle, and a connecting block 34 is fixedly connected to the other end of the wire rope 33.

[0030] The swing assembly includes a mounting base 20, a swing rod 21, and a support base 25;

[0031] Mounting base 20 is fixedly connected to the front side of support plate 10 by bolts. Mounting block 22 is fixedly connected to the rear side of swing rod 21. Mounting block 22 is rotatably connected to mounting base 20 through pivot shaft 1. Mounting block 23 is fixedly connected to the front side of swing rod 21. Connecting rod 24 is fixedly connected to the front side of mounting block 23. Support base 25 is fixedly connected to the front side of connecting rod 24. Two parallel mounting rods 26 are fixedly connected to the upper side of support base 25, which can be used for the installation of counterweight 27.

[0032] Mounting block 23 is located on one side of connecting block 34, and the two are rotatably connected by rotating shaft 2.

[0033] Both the swing arm 21 and the connecting rod 24 are made of solid stainless steel and can withstand the weight of multiple counterweights 27 (typically, the weight of a counterweight is between 1.25 kg and 1.5 kg).

[0034] Two sets of tensioning and swinging components are provided, symmetrically arranged on the front side of the support plate 10.

[0035] A fixing rod 11 is also fixedly connected to the front side of the support plate 10, which is located between the two swing components. A U-shaped base 12 is slidably mounted on the fixing rod 11. A seat plate 13 is fixedly connected to the upper side of the U-shaped base 12. The U-shaped base 12 can be fixed to the fixing rod 11 by bolts.

[0036] That is, the 27 counterweights are inserted into the mounting rod 29 (the number of counterweights 27 on the two swing components is the same). Under the weight, the swing rod 21 swings down and the support seat 25 falls. The trainee slides the U-shaped base 12 to adjust its position (the position of the seat plate 13 should be in front of the handle 30 so that the trainee can easily carry out the pull training). Then, the bolt is tightened to fix the position of the U-shaped base 12. The trainee holds the handle 30 with both hands and pulls it down, thereby lifting the swing rod 21 through the steel wire rope 33. Then, the trainee lifts his hands and releases the force, and the swing rod 21 swings down according to the weight of the counterweights 27. This is repeated to realize the trainee's pull back muscle training.

[0037] The cushioning assembly includes a base plate 40 and a spring tube 41;

[0038] The base plate 40 can be fixed to the ground with bolts. When no counterweight 27 is placed on the support base 25, the base plate 40 is located below the support base 25 and remains horizontal with it. The spring tube 41 is fixedly connected to the upper side of the base plate 40, and its upper end is fixedly connected to the lower side of the support base 25. The spring tube 41 is made of a steel spring that can withstand a certain weight (because the counterweight 27 has weight, ordinary springs are easy to be damaged. The steel spring has a certain degree of hardness, which can not only provide a certain support effect, but also limit the weight of the trainee's pulling training).

[0039] In actual operation of this embodiment, the counterweight 27 is inserted into the mounting rod 26. Under the weight, the swing rod 21 swings down and the support seat 25 falls. The trainee slides the U-shaped base 12 to adjust its position (the position of the seat plate 13 should be in front of the handle 30 so that the trainee can easily perform pull training). Then, the bolt is tightened to fix the position of the U-shaped base 12. The trainee holds the handle 30 with both hands and pulls it down, thereby lifting the swing rod 21 through the wire rope 33. Then, the trainee lifts up and releases the force, and the swing rod 21 swings down according to the weight of the counterweight 27. This reciprocating motion realizes the trainee's pull back muscle training.

[0040] It should be noted that lubricating oil can be added to pivot one and pivot two regularly for maintenance to keep the swing arm rotating smoothly.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, various modifications and variations are possible with this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
