[0099] The household nine-in-one multipurpose fitness machine according to the present application includes nine basic training actions, including four mechanical actions, four free weight training actions, and one aerobic exercise. Specifically, the nine basic training actions include: 1 high-position pull-down handle, 2 bird pinching chest handle, 3 sitting posture pinching chest arm swinging, 4 sitting posture chest pushing handle, 5 non-independent rowing machine, 6 chin-up handle, 7 free weight training hook, 8 Smith slide block, and 9 L-shaped double bar arm bending support. The specific structures of the other parts except for the specific structures of the parts indicated by the embodiments of the present application, including the connection with the fitness machine frame and the movement traction method, can all adopt the existing fitness machine technology, and will not be described herein. It should be understood that the steel wire ropes described at different positions in the present application are steel wire ropes in the traction system, which can be multiple or discontinuous steel wire ropes, and are set according to the actual traction requirements.

[0100] The mechanical action traction force distribution system of the household nine-in-one multipurpose fitness machine according to the present application can provide traction force for five mechanical actions, including high-position pull-down, bird pinching chest, sitting posture pinching chest, sitting posture chest pushing, and rowing exercise.

[0101] According to the household nine-in-one multipurpose fitness equipment of the present application, the first Smith slide rail 91 and the second Smith slide rail 92 respectively serve as the front uprights of the fitness equipment frame, and in addition to serving as the uprights of the overall frame, they also serve as the support frames for the double-bar arm bending and stretching, and the support frames can also serve as the protective bars of the double bar.

[0102] According to the household nine-in-one multipurpose fitness equipment of the present application, the advantages not only lie in the increase of a certain function, but more importantly, the light weight is realized by the combination of several innovative, multipurpose components and frames, and in the same geometric size, it is the design scheme with the most training functions, the lightest weight, the strongest structure, the most material saving, and the easiest transformation into a commodity.

[0103] As shown in Figures 9-11 the top-mounted sitting chest press device, the device comprises a cross beam 21, a first guide rail 901 and a second guide rail 902 arranged on the top of the fitness equipment frame as longitudinal beams, two ends of the cross beam 21 are respectively provided with linear bearings 211 and are movably installed on the first guide rail 901 and the second guide rail 902 through the linear bearings 211; two swing arm bearings 212 are arranged on the cross beam 21, and the swing arm bearings 212 are respectively connected with the chest press swing arms 22 arranged below the cross beam 21.

[0104] The top of the chest press swing arm 22 is further provided with a swing arm wheel disc 23, the swing arm wheel disc 23 is provided with a steel wire rope 8 arranged around the outer periphery of the swing arm wheel disc 23, one end of the steel wire rope 8 is fixed on the swing arm wheel disc 23, and the other end of the steel wire rope 8 is turned around the outer periphery of the swing arm wheel disc 23 and connected to the counterweight piece 99 through a turning pulley set 24.

[0105] The turning pulley set 24 is arranged below the linear bearings 211 at both ends of the cross beam 21.

[0106] The steel wire rope 8 is connected to the counterweight piece 99 through the turning pulley set 24 and then through a compensation pulley set 25.

[0107] The compensation pulley set 25 comprises a first driven wheel 251, a compensation wheel 252 and a second driven wheel 253, the steel wire rope 8 is turned through the first driven wheel 251 and then to the compensation wheel 252, and after being turned through the compensation wheel 252, the steel wire rope 8 is connected to the counterweight piece 99 through the second driven wheel 253.

[0108] The swing arm wheel disc 23 is further provided with an opening and closing pin 26.

[0109] The chest pressing and pushing arm 22 comprises an arm action lever 221 for user operation, an arm connecting lever 222, and an arm force receiving lever 223 connected with the arm bearing 212, and the arm action lever 221 and the arm force receiving lever 223 are connected through the arm connecting lever 222.

[0110] The two ends of the arm connecting lever 222 are connected with the arm action lever 221 and the arm force receiving lever 223 through the arc connecting segments 224 respectively.

[0111] The bottom end of the arm connecting lever 222 is further provided with a chest pushing forward bearing 27.

[0112] The bottom end of the arm action lever 221 is further provided with a sitting chest pushing handle 28.

[0113] The top-mounted sitting chest pressing and pushing device according to the embodiment of the present application uses guide rails instead of longitudinal beams, and realizes multipurpose use of components. As a preferred embodiment, the first guide rail 901 and the second guide rail 902 are optical axis guide rails.

[0114] The chest pressing and pushing arm 22 is connected with the arm bearing 212 below the cross beam 21, and the shaft end top of the chest pressing and pushing arm 22 connected with the arm bearing 212 can be provided with a detachable axial limiting device for preventing the chest pressing and pushing arm 22 from falling, such as a limiting gasket fixed on the shaft end top and covering the inner ring of the bearing, a thrust bearing device, and the like.

[0115] The chest pressing and pushing arm 22 can act as a chest pressing arm and a chest pushing arm. The function is to release the torsional force of the arm wheel disc, so that the force of the sitting chest pressing and pushing is consistent.

[0116] The arm wheel disc generates a rotating torsional force, and the steel wire rope is pulled from the left and right sides. The compensating wheel uses the principle of the effort reverse pulley, when the steel wire rope passes through the compensating wheel, the reverse pulling force is doubled, and the stroke of the counterweight piece is also doubled, which improves the torsional force of the arm wheel disc. The driven wheel (first driven wheel and second driven wheel) does not generate a longitudinal pulling force when the steel wire rope passes through, which turns the steel wire rope and provides a left-right transverse pulling force to the compensating wheel.

[0117] The opening and closing pin 26 is a mode conversion switch for chest pressing and pushing movement. When the opening and closing pin 26 is inserted into the arm wheel disc 23 and the cross beam 21, the arm wheel disc 23 cannot rotate relative to the cross beam 21, and vice versa when the opening and closing pin 26 is removed.

[0118] The chest pushing forward bearing 27 does not work when sitting and clamping the chest, but generates traction when pushing the chest. The outer wall of the chest pushing forward bearing 27 is connected with the steel wire rope 8 and connected with the counterweight plate 99 through the steering wheel group. When the cross beam 21 moves along the first guide rail 901 and the second guide rail 902, the counterweight plate 99 provides traction for the chest pushing arm 22 through the chest pushing forward bearing 27.

[0119] The overhead sitting chest clamping and pushing device according to the present application has a smoother running track than previous products. Two-directional traction provided by the traction system composed of the counterweight plate 99 and the steel wire rope 8 on the public platform of the traction force distribution system, i.e. the fitness equipment frame, is utilized. In the sitting chest clamping action, the transverse traction is utilized, and in the sitting chest pushing action, the longitudinal traction is utilized.

[0120] The traditional sitting chest clamping and pushing device assembly utilizes traction in one direction, and the torque distribution utilizes the lever principle. In the sitting chest pushing action, the running track has an arc.

[0121] The overhead sitting chest clamping and pushing device according to the present application adopts a linear bearing for the chest pushing action through the cross slide structure, so the track is straight, and more in line with ergonomics. The guide rail replaces the longitudinal beam, reducing the structure weight. The overhead design releases the lower space, providing installation conditions for other exercise equipment.

[0122] As shown in Figures 4-8 The non-fixed openable Smith kit includes the first Smith slide rail 91 and the second Smith slide rail 92 arranged as front side columns on the fitness equipment frame. The front and rear sides of the first Smith slide rail 91 and the second Smith slide rail 92 are respectively provided with a plurality of positioning holes 910 used as barbell protection lever positioning holes and Smith slide block pin hanging holes.

[0123] The first Smith slide rail 91 and the second Smith slide rail 92 are respectively provided with a Smith slide block 1.

[0130] The top and bottom of the front compartment 11 are provided with through holes between the front roller bearing set 111 and the rear roller bearing set 112, when the Smith sliding block 1 is installed on the first Smith sliding rail 91 and the second Smith sliding rail 92, the first Smith sliding rail 91 and the second Smith sliding rail 92 pass through the Smith sliding block 1 through the through holes and the space between the front roller bearing set 111 and the rear roller bearing set 112.

[0131] The fitness equipment frame is also provided with a first middle frame 95 and a second middle frame 96 parallel to the first Smith sliding rail 91 and the second Smith sliding rail 92, the front side or front and rear of the first middle frame 95 and the second middle frame 96 is provided with a plurality of middle frame positioning holes 950; a first barbell protection rod 141 and a second barbell protection rod 142 are also provided, the front and rear ends of the first barbell protection rod 141 are respectively inserted into the positioning hole 910 of the first Smith sliding rail 91 and the middle frame positioning hole 950 of the first middle frame 95, and the front and rear ends of the second barbell protection rod 142 are respectively inserted into the positioning hole 910 of the second Smith sliding rail 92 and the middle frame positioning hole 950 of the second middle frame 96.

[0132] The barbell U-shaped clamp slot 1220 of the Smith sliding block 1 or the barbell outer hook 114 is provided with a universal barbell 15, and the first barbell protection rod 141 and the second barbell protection rod 142 are respectively located below the Smith sliding block 1 installed on the first Smith sliding rail 91 and the second Smith sliding rail 92.

[0133] The bottom of the Smith sliding block 1 is also provided with an escape damping spring pad 13.

[0134] The first and second Smith rails 91 and 92 serve as the front uprights of the fitness machine frame. The front of the rails has a positioning hole for the barbell guard (anti-escape bar guard), while the back of the rails also has a positioning hole for the barbell guard (anti-escape bar guard), which also serves as a mounting hole for the Smith slider pin. This fitness machine is a full-frame model, with the Smith rails serving as uprights, providing support for the barbell. The barbell is universal and detachable.

[0135] The roller bearing is used to drive the Smith slider to slide on the Smith guide rail. The pin is used to open and close the Smith slider. The barbell U-shaped clamp is used to clamp the barbell bar. Pulling it backward can lock the barbell bar and pull out the pin, so that the barbell can move along a fixed trajectory. The pin return spring is used to assist in returning to its original position when closed. The slider opening positioning magnet is used to open and position. It attracts the metal wall fixed inside the rear wall of the rear compartment 12 or the rear wall of the rear compartment 12 directly made of metal. When the pin is pulled to open and lock the barbell bar, the two tend to attract or maintain attraction due to the close distance. According to the Smith slider of the present application, the bar slides after locking and opens after closing, which is safer. The pin positioning peephole provides auxiliary positioning when the Smith module is closed. The barbell bar external hook is used for assistance outside the frame. The escape bar damping spring pad is used to protect against impact.

[0136] A Smith slide balancing mechanism 16 is also provided, comprising four synchronous gears. The left and right upper wheels are connected by a shaft, and the lower wheel and upper wheel are connected by a synchronous belt. The synchronous belt is connected to the Smith slide rail. This ensures that the Smith slide is synchronized up and down and balanced left and right as it slides.

[0137] Traditional Smith assemblies are fixed, but their disadvantages include excessive weight and the need for linear optical axis guides, pin columns, and a fixed barbell. Mounting the assemblies within the frame overlaps with the tracks of other equipment, requiring the protective bar and dip bracket to be mounted outside the frame, placing stringent demands on material strength.

[0138] The non-fixed, openable Smith assembly of this application utilizes the frame's uprights as guide rails, with a Smith slider that can be balanced left and right and synchronized up and down. When the pin is open, the barbell is locked and moves along a fixed trajectory. When the pin is closed, the universal barbell can be removed and used for other exercises.
