Description

[0001] This application is a divisional application of the case with application date "2019-10-29", application number "2019110345773" and application name "A comprehensive training frame". Technical Field

[0002] The invention relates to the technical field of fitness equipment, in particular to a comprehensive training rack. Background Art

[0003] With the improvement of living standards and people's emphasis on health, fitness has become an indispensable part of people's daily life, and barbells are a kind of fitness equipment that people use more frequently, and barbells are also widely used. However, when using a barbell, if it is used improperly or not properly protected, it is easy to cause damage to the user. For example, if the beginner's movements are not standardized, the trainer is physically exhausted or the hands slip, causing the barbell to fall suddenly, the consequences are disastrous. Therefore, when doing barbell exercises, professionals are usually required to assist in the training, but the trainers may also be distracted at times, which also poses risks and adds extra manpower. In the related art, some solutions use dampers to buffer the descent of the barbell, but the existing buffering solutions have poor buffering effects, there are still safety hazards, and the protection of the trainer's wrists is not considered. Summary of the invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a comprehensive training frame, which can effectively assist trainees in barbell training, and can slow down the falling speed of the barbell when it suddenly falls, has a good buffering effect, and can protect the trainees' wrists, effectively protect the trainees, avoid injuries, and allow the trainees to confidently and boldly carry out effective barbell training.

[0005] A comprehensive training frame according to an embodiment of the present invention comprises: a supporting main frame having a base, and vertical supporting rods are symmetrically arranged on both sides of the base; a barbell assembly having supporting plates arranged symmetrically on both sides, the supporting plates are slidably connected to the vertical supporting rods, a barbell rod is installed at the front end of the supporting plate, and both ends of the barbell rod are provided with protruding ends for installing barbell plates, and the barbell rod is fixedly installed at the front ends of the two supporting plates through two bearings; a bracket body, one end of which is hinged to the supporting main frame, and the other end is connected to one end of a pull rope, two fixed pulleys are arranged on the upper part of the supporting main frame, and the bracket body is provided with a movable pulley, and the other end of the pull rope passes around one of the fixed pulleys, passes around the movable pulley downward, and then passes around the other fixed pulley upward and is connected to the barbell assembly; The above technical solution has at least the following beneficial effects: by installing the barbell assembly on the vertical support rod of the supporting main frame, the barbell assembly is restricted to only move up and down in the vertical direction, so that the supporting main frame acts as a sparring partner to assist in training. Therefore, when the trainee performs barbell training, the barbell can only move up and down without deviating forward and backward or left and right, thereby ensuring the safety of the trainee; and, when the trainee grasps the barbell bar and lifts the barbell assembly, the barbell bar can rotate with the rotation of the trainee's wrist during the ascent, so as to unload the torque brought to the wrist by the barbell and protect the trainee's wrist. At the same time, the barbell assembly is connected to the support body and the one-way damping device by a pull rope passing through a fixed pulley, a movable pulley arranged on the support body and another movable pulley. When the barbell rises, the support body descends around the hinge point due to its own gravity, and the one-way damping device is gradually compressed, but no damping is generated, thereby ensuring normal lifting training; when the barbell falls, the support body is pulled up around the hinge point by the pull rope, and the one-way damping device stretches and generates damping buffering, thereby slowing down the falling speed of the barbell. Therefore, when the trainer loses the barbell due to physical exhaustion or hand slippage, it can buffer the sudden fall of the barbell, slow down the falling speed, and further ensure the safety of the trainer. At the same time, thanks to the connection method of the pull rope and the movable pulley, the one-way damping device with a shorter piston stroke can effectively buffer the barbell assembly with a larger stroke, and saves effort, effectively improves the buffering effect on the barbell assembly, and ensures the safety of the trainer.

[0019] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0020] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The embodiment of the present invention provides a comprehensive training frame, including a supporting main frame 200, having a base 230 similar to an H shape, and smooth cylindrical vertical support rods 210 are symmetrically arranged on both sides of the base 230; a barbell assembly 100, having a supporting plate 140 arranged symmetrically on both sides, the supporting plate 140 is slidably connected to the vertical support rod 210 to ensure that the barbell assembly 100 can only move in the vertical direction, the supporting plate 140 is a hollow design to reduce the overall weight of the barbell assembly 100, and a standard barbell rod 110 is also installed at the front end of the supporting plate 140, and both ends of the barbell rod 110 are provided with an extended end 111 for installing barbell plates, and the number of barbell plates can be adjusted to adjust the training weight; a bracket 700, one end of which is hinged at the lower end of the middle part of the rear side of the supporting main frame 200, and the other end is connected to one end of the pull rope 500, and two fixed pulleys 900 are arranged on the upper part of the supporting main frame 200, and the pull rope After the other end of 500 passes upward around a fixed pulley 900 provided on the upper part of the supporting main frame 200, it passes downward around a movable pulley 710 provided on the supporting body 700, then passes upward around another fixed pulley 900 provided on the upper part of the supporting main frame 200, and finally connects downward to the barbell assembly 100; the one-way damping device 800 is placed directly below the supporting body 700, one end of which is hinged to the lower end of the supporting main frame 200, and the other end is connected to the middle lower end of the supporting body 700. The one-way damping device 800 is provided with nine gradient-adjustable regulating valves, which can be adapted to the buffering of barbell plates of different weights. In addition, thanks to this connection method of the pull rope 500, the one-way damping device 800 with a shorter piston stroke can effectively buffer the barbell assembly 100 with a larger stroke, that is, if the barbell assembly 100 rises or falls a distance of 30 cm, correspondingly, the piston of the one-way damping device 800 is compressed or stretched less than a distance of 10 cm.

[0021] When the trainer applies an upward force to the barbell bar 110, the barbell assembly 100 moves upward as a whole, loosening the pull rope 500, and the support body 700 moves downward around the hinge point due to its own gravity, thereby compressing the one-way damping device 800, but the one-way damping device 800 does not produce any damping during this process, ensuring normal training. Due to the sliding connection between the barbell assembly 100 and the support rod 210, the barbell assembly 100 can only move in the vertical direction and will not tilt forward or backward or left or right, ensuring the safety of the trainer and the training effect. When the trainee removes the force on the barbell 110 or the barbell 110 slips out of the trainee's hand due to exhaustion or hand slippage, the barbell assembly 100 will drop rapidly, and the pull rope 500 will bypass the fixed pulley 900 to pull the support body 700 upward around the hinge point, thereby stretching the one-way damping device 800. At this time, the one-way damping device 800 will have a damping buffer, thereby slowing down the descent speed of the barbell assembly 100, further ensuring the safety of the trainee.

[0022] Reference Figure 1 , Figure 2 and Figure 4 It can be understood that each support plate 140 is provided with four rollers 130, and the four rollers 130 are divided into two groups and clamp a vertical support rod 210 from the front and rear sides, wherein the group of rollers 130 on the rear side can be adjusted in the front-to-back direction by adjusting the pin 150, so as to adjust the tightness of the fit between the barbell assembly 100 and the vertical support rod 210. When the barbell assembly 100 rises or falls, the front and rear groups of rollers 130 roll up or down on the smooth surface of the vertical support rod 210. Since the two groups of rollers 130 fit the vertical support rod 210 tightly, the barbell assembly 100 can only move in the vertical direction, and cannot deviate forward and backward or left and right. Therefore, when the trainer performs barbell training, the barbell can be lifted normally without tilting forward and backward or left and right, thereby ensuring the trainer's safety and training effect.

[0023] In some other embodiments, it is understood that two vertical support rods 210 are respectively arranged on both sides of the base 230, and each support plate 140 is provided with two rollers 130 arranged up and down, and the two rollers 130 are clamped and installed between the two vertical support rods 210. When the barbell assembly 100 rises or falls, the two rollers 130 roll up or down along the surface of the vertical support rods 210 between the two vertical support rods 210, and the two vertical support rods 210 clamp the two rollers 130 arranged up and down, so that the barbell assembly 100 can only move in the vertical direction, and cannot be offset forward and backward or left and right. Therefore, when the trainer performs barbell training, the barbell can be lifted normally without tilting forward and backward or left and right, ensuring the trainer's safety and training effect.

[0024] In some other embodiments, it is understood that each support plate 140 is provided with two linear motion bearings arranged vertically, and the two linear motion bearings are sleeved on a vertical support rod 210. When the barbell assembly 100 rises or falls, the two linear motion bearings slide upward or downward on the smooth vertical support rod 210, and the two linear motion bearings arranged vertically are tightly mounted on the vertical support rod, so that the barbell assembly 100 can only move in the vertical direction, and cannot be offset forward and backward or left and right. Therefore, when the trainer performs barbell training, the barbell can be lifted normally without tilting forward and backward or left and right, ensuring the trainer's safety and training effect.

[0025] Reference Figure 1 and Figure 4 It can be understood that a cross bar 160 is installed at the rear end of the two support plates 140, and a pull rope connection point 162 is set in the middle of the cross bar 160 to connect the pull rope 500. By installing a cross bar 160, the barbell assembly 100 forms a closed rectangle, and the overall strength of the barbell assembly 100 is strengthened. At the same time, the cross bar 160 can balance the gravity of the barbell assembly 100 in the front and rear directions, so that the center of gravity is placed in the middle position of the barbell assembly 100 to enhance the stability of the barbell assembly 100; in addition, a pull rope connection point 162 is set in the middle of the cross bar 160 and connected to the pull rope 500. When the barbell assembly 100 descends, the upward traction of the pull rope 500 is transmitted to the support plates 140 on both sides through the cross bar 160, so that the barbell assembly 100 slows down the descent speed and ensures a buffering effect.

[0026] Reference Figure 1 and Figure 6 It can be understood that two columns 220 are symmetrically arranged on both sides of the base 230, and a row of circular up-and-down adjustment holes 221 are arranged on the columns 220, and a plurality of cylindrical limiting columns 222 are installed on the up-and-down adjustment holes 221, and the limiting columns 222 have interference portions with the ends of the crossbar 160 to carry the barbell assembly 100. In this way, the barbell assembly 100 can be preset to an initial position to adapt to the different needs of trainees of different heights. At the same time, when the barbell assembly 100 falls, the barbell assembly 100 stops at a preset height due to the limiting columns 222, and will not continue to fall to generate the risk of injuring the trainee, thereby further ensuring the safety of the trainee.

[0027] Reference Figure 1 It can be understood that fixing blocks 240 are welded on both sides of the bottom of the rear end of the base 230, and the comprehensive training frame can be fixed to the ground by fasteners such as screws. At the same time, the high-strength support main frame 200 is used to ensure the stability of the comprehensive training frame, thereby further ensuring the safety of the trainee.

[0028] Reference Figure 1 and Figure 2It can be understood that the cylinder shock absorber 300 is installed on the top of the support main frame 200, and correspondingly, the cross bar 160 is provided with a contact 161. When the barbell assembly 100 moves close to the top, the contact 161 just contacts the cylinder shock absorber 300. When the trainer exerts excessive force to lift the barbell assembly 100 upwards, so that the barbell assembly 100 is close to the top of the support main frame 200, the cylinder shock absorber 300 will support the contact 161 of the cross bar 160, which can effectively reduce the collision between the barbell assembly 100 and the support main frame 200, and avoid damage to the support main frame 200.

[0029] Reference Figure 1 and Figure 2 It is understandable that there are two cylinder shock absorbers 300, which are respectively installed on the left and right sides of the top of the support main frame 200, facing downward. When the cylinder shock absorber 300 produces a buffering and shock absorbing effect, the arrangement of the left and right sides can balance the forces on the left and right sides, enhance the buffering and shock absorbing effect, and further reduce the risk of damaging the support main frame 200.

[0030] Reference Figure 1 and Figure 2 It can be understood that the pull-wire displacement sensor 400 and the display screen 600 are respectively installed in the middle of the top and the middle of the front end of the supporting main frame 200, the pull-wire displacement sensor 400 is located directly above the cross bar 160, and the pull wire is connected to the middle of the cross bar 160, and the display screen 600 is facing the trainee; in addition, the pull-wire displacement sensor 400 is electrically connected to the display screen 600, and the data such as the displacement and speed of the barbell assembly 100 measured by the pull-wire displacement sensor 400 will be transmitted to the display screen 600 in real time, so that the trainee can understand his movements in real time, which is helpful to monitor and improve the training effect.

[0031] Reference Figure 1 and Figure 4 It is understood that the barbell bar 110 is fixedly mounted on the front ends of the two support plates 140 through two bearings 120, so that the barbell bar 110 can rotate arbitrarily. When the trainer holds the barbell bar 110 and lifts the barbell assembly 100, the barbell bar 110 can rotate with the rotation of the trainer's wrist during the lifting process to unload the torque brought by the barbell to the wrist and protect the trainer's wrist.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
