The front of the machine body is a screen. The pull rope is coiled inside the machine body and used for transmitting the pulling force on two sides. The free ends of the coiled two-side pull ropes extend outwards, and after resistance is applied by the resistance component, the free ends of the coiled two-side pull ropes respectively penetrate through the support arms on the two sides of the machine body and are connected with the holding piece. When the user uses the device, the user only needs to directly or indirectly hold the actuators by two hands respectively, and the two groups of pull ropes are pulled outwards.

This application can adjust driving belt's tensile force through adjusting straining device, the advantage of doing so lies in, because the fitness machine inner space is limited, synchronous rate requirement to motor and differential wheel is higher when using simultaneously, consequently, requirement to driving belt's tensile force is higher, if there is not adjustable straining device, it is difficult directly to install the great belt of tensile force on motor and differential wheel, and adopted above-mentioned straining device after, adjust straining device earlier and make driving belt's tensile force be in lower level, then install the belt on motor and differential wheel, adjust straining device again at last and make driving belt's tensile force be in higher level, satisfy the demand of using. By adopting the scheme, on one hand, the tensioning force of the transmission belt during the working of the motor can be ensured, meanwhile, the transmission belt can be conveniently installed, and the assembling efficiency of the body builder is effectively improved under the condition of ensuring the quality.

Further, the tensioning mechanism includes: a connecting plate; a tension wheel and an adjusting rod which are arranged on the connecting plate; a fulcrum bar penetrating through the connecting plate; a pressurizing structure arranged on the fulcrum bar; the pressurizing structure acts on the adjusting rod to drive the connecting plate to rotate by taking the fulcrum rod as a pivot, so that the tension pulley compresses the transmission belt to adjust the tension force of the transmission belt. The transmission belt is contacted with the tension wheel, the tension wheel acts on the transmission belt, the transmission belt can apply an acting force on the tension wheel, the tension wheel drives the connecting plate to rotate under the action of the acting force, the connecting plate drives the adjusting rod to rotate together in the rotating process, the fulcrum rod and the connecting plate can rotate relatively, so that the fulcrum rod is not moved, the pressurizing structure is connected between the fulcrum rod and the adjusting rod and acts on the fulcrum rod and the adjusting rod, when the connecting plate moves, the adjusting rod moves along with the connecting plate due to the fact that the fulcrum rod is not moved, the pressurizing structure acts between the fulcrum rod and the adjusting rod in the moving process of the connecting plate, the pressurizing structure applies a restoring force to the adjusting rod, the adjusting rod drives the connecting plate to move to the original position together, and the connecting plate drives the tension wheel to move simultaneously due to the pressurizing structure to force the connecting plate to return to the original position, and then the tension wheel is to the reverse effort of exerting of drive belt, makes drive belt be in the state of tensioning, when using like this, can not only cushion the effort on the drive belt, and simultaneously, drive belt is under the tensioning state always, and the output that drive belt connects can better act on the stay cord, improves tensile output effect to drive belt does not return the normal use that influences other inside parts.

Further, the pressurization structure is the torsional spring, and the torsional spring includes both ends and is located the rotating spring between the both ends, the one end of torsional spring is connected on adjusting the pole, and the other end is connected on fixed knot in the fitness equipment constructs, and the rotating spring suit is on the outer wall of fulcrum pole, and the torsional spring exerts pressure to fixed knot structure and regulation pole.

The torsion spring belongs to the group of helical springs, the ends of which are fixed to other components, which, when they rotate around the spring centre, pull them back to the initial position, generating a torque or rotational force. The torsion spring can store and release angular energy or statically fix a certain device by rotating a moment arm around the central axis of the spring body. Such springs are typically solid, however, the coils are spaced to reduce friction. They produce resistance to rotational or rotational external forces. The handedness (clockwise or counterclockwise) of the torsion spring is designed to determine the handedness of the spring, depending on the application requirements. The turns are either tightly wound or separately wound to accommodate torsional loading, and the ends of the spring may be wound as hook-shaped or straight torsion arms.

In this scheme, the one end of torsional spring is connected on adjusting the pole, and the other end is coiled into hook-like, connects on fixed knot structure when using, and the rotating spring between both ends is the spring coil suit promptly on the fulcrum pole, and when the tension pulley drove the connecting plate rotatory like this, the connecting plate drove when adjusting the pole rotation, and the torsional spring passes through the fulcrum pole and acts on adjusting the pole, makes the reverse rotation of connecting plate reply the primary importance, and the connecting plate drives the tension pulley simultaneously and replies the primary importance, and then exerts an effort to driving belt, makes driving belt be in the tensioning state.

Specifically, the one end of the fulcrum bar of this scheme passes the connecting plate and is connected with the mounting panel. The connecting plate can rotate on the fulcrum rod, the fulcrum rod fixes the connecting plate on the mounting plate through threaded connection, operation is convenient during installation, one end of the transmission belt is connected with the motor, the other end of the transmission belt is connected with the differential wheel, and the tension wheel is located between the motor and the differential wheel. The motor is connected with the differential wheel through a transmission belt, the motor adjusts differential through the differential wheel, and the transmission belt is located on one side of the tension wheel close to the fulcrum rod.

When using, through the transmission belt between this scheme regulation differential wheel that can be better and the motor, make it be in the state of straining, more be favorable to using, the tension pulley can the rotation in a circumferential direction on the connecting plate, therefore when transmission belt moved on the tension pulley, the rotation of tension pulley self and the rotation of connecting plate can both cushion the power that receives on the transmission belt, avoid transmission belt to be broken. And when the device is installed, the tension pulley can be pulled outwards when the transmission belt needs to be installed after the device is installed, then the transmission belt is installed on the side surface of the tension pulley, and the tension pulley applies tension to the transmission belt, so that the device can be installed quickly when the device is installed.

Secondly, the distance between the tension pulley of this scheme and the fulcrum pole is greater than the distance between regulation pole and the fulcrum pole. The acting force on the torsional spring is greater than the acting force when the driving belt acts on the tension pulley, and just so the torsional spring can act on the adjusting rod better, so that the tension pulley on the connecting plate returns to the original position, and the use efficiency is improved.

And the length of the torsion spring is shorter, and the length between the adjusting rod and the fulcrum rod is shorter, so that the torsion spring can be more suitable for being connected and used.

Furthermore, the method also comprises the following steps of,

the first adjusting assembly is used for adjusting the rotation angle of the track on the machine body;

the second adjusting assembly is used for adjusting the axial position of the adjusting seat in the track;

and the third adjusting component is used for adjusting the rotating angle of the end head on the adjusting seat.

According to the scheme, the rotating angle of the track on the machine body is adjusted through the first adjusting component, so that the support arm positioned on the track can have different angle orientations, and the device is suitable for users with different arm unfolding and opening and closing angles during force exerting; the position of the adjusting seat in the track is adjusted through the second adjusting component, so that the use requirements of users with different heights are met; the rotation angle of the end head on the adjusting seat is adjusted through the third adjusting component, and the use requirements of users with different heights and different force applying habits are further met. This application is through three group adjusting part's combined action, and the commonality when showing the chest expander machinery and using has enlarged application scope obviously.

Furthermore, first adjusting part include with track fixed connection's fifth pivot, fixed cover is established the fluted disc in the fifth pivot, still including be used for with fluted disc assorted tooth spare, the tooth spare by drive arrangement drive with the fluted disc meshes and breaks away from. The track rotates synchronously along with the rotation of the fifth rotating shaft, and the purpose of adjusting the angle of the track is achieved. When the angle of the track does not need to be adjusted, the driving device drives the toothed piece to be meshed with the fluted disc, at the moment, the fluted disc cannot rotate due to the limit of the toothed piece, and the fifth rotating shaft and the track cannot rotate; when the track needs to be adjusted, the driving device drives the toothed piece to be separated from the fluted disc, and at the moment, the angle of the track can be flexibly adjusted. The driving device in the scheme can be realized by adopting any power equipment which can drive the tooth-shaped part to act in the prior art.

Furthermore, the second adjusting assembly comprises a plurality of pin holes axially arranged on the track and a positioning pin connected with the adjusting seat, and the positioning pin can be inserted into the pin holes; the handle is used for controlling the positioning pin to go in and out of the pin hole. In the scheme, the track and the adjusting seat are connected through the pin holes and the matched positioning pins, each pin hole provides one positioning gear, the adjusting seat moves to the pin hole in a proper position, and the positioning pins directly or indirectly connected with the adjusting seat are inserted into the pin holes. The positioning pin can enter and exit the pin hole and can be controlled by the handle, so that the flexible operation and use of a user are facilitated. The problem of among the prior art support arm axial position adjustment mode structure complicacy, maneuverability are poor is solved to this scheme, has realized simplifying the axial and has adjusted the structure, provide more convenient axial adjustment mode's purpose for the user.

Furthermore, the third adjusting component comprises a plurality of slots which are arranged on the adjusting seat and annularly distributed along the rotation direction of the end head, a positioning block matched with the slots is arranged on the end head, and the positioning block can enter and exit the slots. The ring shape that the slot distributes in this scheme and end pivoted movement track phase-match to guaranteed that the locating piece on the end can rotate to just to arbitrary slot. The shape of the positioning block is matched with that of the slot, so that the positioning block can be inserted into the slot and also can be taken out of the slot. When the positioning block is used, the positioning block enters a certain slot to position the angle of the end head, namely the angle of the support arm connected with the end head; if the angle of the end needs to be adjusted, the positioning block is only required to be taken out of the current slot, the end is rotated to adjust the angle, the positioning block is aligned with the other slot, and then the positioning block is inserted into the slot. Every slot can correspond the gear of an end angle modulation in this scheme, only need insert through the control locating piece with take out can realize showing the structure of having simplified in comparison with prior art, very big user's use of having made things convenient for, improved maneuverability to the regulation of end angle.

Furthermore, the device also comprises an elastic part and a rigid part which are connected with the adjusting seat; when the external force born by the adjusting seat is within the threshold value, the adjusting seat is coupled with the track through a roller on the elastic piece; when the external force born by the adjusting seat exceeds a threshold value, the adjusting seat is coupled with the track through the rigid piece.

The problem that the eccentric wear phenomenon of a support arm adjusting structure in the prior art is serious in the using process and the blocking feeling of a user is obvious easily caused in the force application process is solved. The applicant has found, after a great deal of research, that the reason for this is that the pulling force exerted by the user in use cannot be perfectly directed axially of the arm, and that there is necessarily a deviation that is transmitted to the adjustment structure of the end of the arm, causing a feeling of jamming and an eccentric wear to occur. In order to overcome the problem, the application is also provided with an elastic part and a rigid part which are connected with the adjusting seat; when the external force born by the adjusting seat is within the threshold value, the adjusting seat is coupled with the track through a roller on the elastic piece; when the external force born by the adjusting seat exceeds a threshold value, the adjusting seat is coupled with the track through the rigid piece. The elastic member and the rigid member may be directly or indirectly connected to the adjustment seat, and the specific connection manner is not limited herein. The elastic piece is provided with a roller and provides prestress for the adjusting seat; the rigid part is made of any existing rigid material. When the adjusting seat is used, the adjusting seat is assembled in the track, and when the external force borne by the adjusting seat is within a threshold value, the adjusting seat is coupled with the external track through the roller on the elastic piece; when the external force borne by the adjusting seat exceeds a threshold value, the adjusting seat is coupled with the external track through the rigid part; the threshold is a stress critical point at which the elastic member is deformed sufficiently, and a person skilled in the art can select and set the threshold according to the specific material, shape and the like of the elastic member, which is not described herein in detail. That is, when no external force is applied to the adjusting seat through the force applying end of the exercise device, the roller extends to a more outer direction than the rigid member. When the user is not using or exerting force, the roller positioned on the outer side is always in contact with the outer rail; when a user uses the fitness equipment, acting force is transmitted to the adjusting seat through the force application end and is transmitted to the rigid part through the adjusting seat, if the acting force deviates instead of the axial direction, the component force in the deviating direction pushes the rigid part to one side direction, and the elastic part is driven to deform in the process to generate resetting force; if the external force is relatively small and does not exceed the threshold value, the rigid part cannot be pushed to be in contact with the external track, at the moment, the contact with the external track is still realized by the wheels, and the wheels which are movably connected have the rotation capacity, the small-amplitude rotation can be carried out to overcome the integral deflection of the elastic assembly caused by the deviation of the external force, meanwhile, the rolling friction is generated between the wheels and the external track, the friction resistance is relatively small, further, the eccentric wear phenomenon of the force application end adjusting structure of the fitness equipment in the prior art is overcome, meanwhile, the sliding friction is changed into the rolling friction, and the blocking feeling of a user can be effectively reduced; certainly, if the external force is relatively large, the external force exceeds the deformation threshold of the elastic part and pushes the rigid part to be in contact with the external track, and the user performing body-building exercise can obviously feel that the resistance is suddenly increased, so that the force application direction of the user is seriously deviated at the moment, and the user is prompted to correctly apply force in a standard posture for exercise; in addition, the elastic part is seriously deformed in the state, a large amount of acting force deviated by a user is converted into elastic potential energy for storage, the pressure between the rigid part and an external rail is obviously reduced, the eccentric wear phenomenon can be obviously reduced, and meanwhile, due to the serious deformation of the elastic part, larger elastic reset force can be generated, and the eccentric wear pressure can be effectively counteracted; and, a large amount of pressure are undertaken to the rigidity piece under this state, can avoid the gyro wheel to be crushed, improve the whole life of this application. Of course, in the scheme, after the external force disappears, the elastic piece is immediately reset, so that the rigid piece is separated from the contact with the external track and is propped against the external track by the rollers on the two sides again.

Furthermore, the elastic piece comprises two strip-shaped pieces which are fixedly connected through two connecting pieces, the two connecting pieces divide the area between the two strip-shaped pieces into a first mounting part, a second mounting part and a third mounting part in sequence, the roller is arranged on the first mounting part and the third mounting part, and the rigid piece penetrates through the second mounting part;

the roller is rotatably connected to the mounting shaft, first notches are formed in two ends of the mounting shaft, and the two strip-shaped pieces are inserted into the first notches in the two ends of the mounting shaft respectively; a second notch facing the first mounting part and the third mounting part is formed in the strip-shaped part and inserted into the first notch in the mounting shaft; the mounting shaft is sleeved with two bosses, and the roller is positioned between the two bosses;

the rigid part is provided with a limiting mechanism, and the limiting mechanism is used for limiting the elastic part to slide on the rigid part; the limiting mechanism comprises a first limiting rod and a second limiting rod which penetrate through the rigid part, and two strip-shaped parts on each elastic part are located between the first limiting rod and the second limiting rod.

This scheme designs specially the elastic component, including two bar spares, and connects through two connecting pieces between two bar spares, and two bar spares constitute fixed connection's integral type structure with two connecting pieces. The first mounting part and the third mounting part are respectively positioned at two sides of the elastic part, one side of the first mounting part, which is far away from the second mounting part, is opened, and the roller is mounted in the first mounting part; the rigid member passes through the second mounting portion. According to the scheme, the rollers are arranged through the first installation part and the third installation part, so that the rollers are positioned at two ends, the two ends of the elastic piece are compressed inwards under the action of external force, the elastic piece is deformed from two ends, and the elastic piece is ensured to have good deformation and recovery capacity; simultaneously, the second installation part provides installation and positioning space for the rigid part, so that the four directions of the rigid part are limited by the two strip-shaped parts and the two connecting pieces respectively, and the position stability of the rigid part is ensured. The elastic part of the scheme can realize effective connection of the rigid part and each roller, ensures extremely strong structural integrity, and has extremely strong adaptability to overcoming the eccentric wear phenomenon of the force application end adjusting structure of the body-building apparatus.

This scheme all carries out fixed connection through installation axle and two bar spares to each gyro wheel, and its fixed mode has guaranteed that the deformation degree of two bar spares is unanimous for adopting first breach joggle, has avoided taking place the eccentric wear in two bar spares line direction. The connecting mode also solves the problem of difficulty in mounting the roller when the strip-shaped parts are thin, and ensures that the roller rolls between the two strip-shaped parts stably.

Wherein, the second breach plays the effect for installing the axle location, and first breach and second breach match each other and insert mutually, avoid installing the axle and slide on the strip spare, improve the stability in use of this application elastic component. The two bosses limit the roller, so that the roller can only be sleeved on the mounting shaft between the two bosses, and the roller is prevented from contacting with the strip-shaped parts on two sides to interfere the normal rolling of the roller.

The relative position of the elastic part and the rigid part is stable through the limiting mechanism, and the elastic part is prevented from sliding to two sides from the rigid part to cause falling. Carry on spacingly through first gag lever post, the second gag lever post that runs through the rigidity piece to the elastic component, it is concrete, to every strip spare, all by the centre gripping between first gag lever post and second gag lever post, avoid it to the both sides slip. In addition, the limiting mechanism in the scheme can effectively realize the transmission of the acting force besides the limiting function; specifically, promote the rigidity piece through the support and remove to one side when user's application of force skew, the removal of rigidity piece must make the middle part that corresponds the strip piece take place to warp, and because the gyro wheel of elastic component both sides still supports with outside track and leans on the contact, consequently the elastic component can wholly take place to the crooked deformation of intermediate position.

The resistance assembly and the control panel are respectively positioned on two sides of the partition board; a plurality of heat dissipation fans are arranged on the partition board; a plurality of heat dissipation holes are formed in the surface of the machine body.

Compared with the prior art, the invention has the following advantages and beneficial effects:
