Referring to fig. 1-8, the present embodiment provides a strength exerciser not easy to fall off, including: the telescopic module 2, the foot pad module 3, the left adjusting module 6, the right adjusting module 5 and the handle module 1;

the telescopic module 2 comprises a fixed rod 21 and two adjusting rods 22 movably connected with the fixed rod 21; the left adjusting module 6 and the right adjusting module 5 are respectively sleeved on the two adjusting rods 22, and the driving piece on the left adjusting module 6 or the right adjusting module 5 drives the adjusting rods 22 to move inwards or outwards along the length direction of the fixed rod 21; the foot pad modules 3 are respectively arranged at the tail ends of the two adjusting rods 22;

the handle modules 1 are in one-to-one correspondence with the left adjusting module 6 and the right adjusting module 5 and are respectively connected with the rope winding assemblies of the left adjusting module 6 and the right adjusting module 5 through the pull ropes 7; when the handle module 1 drives the pull rope 7 to stretch, the rope winding assembly generates resistance to the pull rope 7 in the opposite direction.

The strength body builder can be installed between a door frame or two walls to provide a single-rod exercise function. The driving piece for changing the relative position relation between the adjusting rod 22 and the fixing rod 21 is integrated on the adjusting module, and the adjusting module also has the function of providing the pull rope 7 for the user to exercise, so that the adjusting module can adjust the length of the telescopic module 2, can provide the pull rope 7 for the user to exercise the pull rope 7, has higher integration level, multiple functions and wide application.

The left adjusting module 6 and the right adjusting module 5 in this embodiment have the same structure, and the right adjusting module 5 is taken as an example for structural description.

The conventional strength body-building device is to prop up the foot pad modules 3 at two ends of the adjusting rod 22 on the wall or the door frame, and prevent the telescopic modules 2 from falling off the door frame by using friction force. This way it must be ensured that the pressure between the footbed module 3 and the wall or door frame is sufficiently high, and once the pressure is too low, the telescopic module 2 will fall down and thus pose a great risk to the life safety of the gymnastics. In order to adapt to door frames or walls with different widths, the length of the telescopic module 2 can be adjusted, so that the telescopic module is shortened in the use process, and the falling accident can easily occur. In this embodiment, the following structure is used to ensure that the usage of the expansion module 2 is not shortened:

first, the fixing rod 21 is a double-ended threaded rod, and the adjusting rod 22 is internally provided with an internal thread. Thus, the adjusting lever 22 can be moved in the axial direction of the double-headed screw rod by rotating relative to the telescopic rod. In order to facilitate the user to drive the adjusting rod 22 to rotate through a driving piece, the driving piece is a knob 51, and a groove 221 for fixedly connecting with the knob 51 is arranged on the outer side wall of the adjusting rod 22; the knob 51 is used for driving the adjusting lever 22 to rotate relative to the fixed lever 21, so that the adjusting lever 22 moves along the axial direction of the fixed lever 21. The adjusting lever 22 can be extended or shortened by rotating the knob 51 clockwise or counterclockwise. Then, only after the installation is completed, the rotation direction of the knob 51 is changed from two directions to one direction, so that the expansion module 2 can be ensured to be only elongated but not shortened in the use process, and the falling-off is naturally avoided. When the user needs to disassemble the exercise machine, the rotating direction of the knob 51 is restored to be bidirectional, and the telescopic module 2 can be easily shortened to disassemble the exercise machine.

For this purpose, in this embodiment, a first ratchet 511 is disposed in the knob 51, the first ratchet 511 is fixedly connected to a button 512, and the button 512 is exposed outside the knob 51; the first ratchet 511 moves from the first position to the second position under the action of the button 512; when the first ratchet 511 is located at the first position, the knob 51 is in one-way limit fit with the first ratchet 52 in the adjusting module through the first ratchet 511; when the first ratchet 511 is located at the second position, the first ratchet 511 is separated from the first ratchet 52 to release the unidirectional limiting engagement. Therefore, when the expansion module 2 needs to be shortened, the knob 51 can be reversely rotated by pressing the button 512, which is very convenient. In addition, the first ratchet 511 is also connected to a return spring 513 such that the first ratchet 511 can be returned to the first position by the return spring 513 after the user releases the button 512.

The pull rope 7 exercises to realize the effect of strength body building, and a user is required to overcome a certain amount of resistance. In order to generate the resistance, the left adjusting module 6 and the right adjusting module 5 are respectively provided with a resistance adjusting mechanism for adjusting the resistance of the rope winding assembly to the pull rope 7. If the resistance can be adjusted, after the user is used to the current resistance, the resistance can be increased to achieve a better exercise effect, and different resistances can be set for families to meet the use needs of people with different strength.

To achieve the effect of resistance adjustment, taking the resistance adjustment mechanism 53 in the right adjustment module 5 as an example, the resistance adjustment mechanism 53 includes an adjustment housing 531, a spring seat 532, a spring 533, and a friction plate group 534; the spring 533 is disposed between the spring seat 532 and the friction plate group 534; the adjusting housing 531 is used for driving the spring seat 532 to move along the axial direction of the spring 533 so as to change the compression amount of the spring 533 and the elastic force of the spring 533 acting on the friction plate group 534; the friction plate group 534 is linked with the pull rope 7, and when the handle module 1 drives the pull rope 7 to stretch, the pull rope 7 drives the friction plate group 534 to rotate relative to the spring 533 so as to generate friction resistance. Therefore, the user can adjust the compression amount of the spring 533 by adjusting the housing 531, so as to change the magnitude of the elastic restoring force of the spring 533 against the friction plate group 534, and when the friction plate group 534 rotates relative to the spring 533 under the action of the pull rope 7, the friction force between the spring 533 and the friction plate group 534 is changed accordingly. This friction provides a resistance to the user's pulling of the cord 7 so that the resistance to the user's pulling of the cord can be adjusted.

In order to enable the user to intuitively see the current resistance, the user can conveniently select a proper resistance value for exercise. The resistance adjustment mechanism 53 further includes a resistance knob 54, and the resistance knob 54 and the adjustment housing 531 are respectively provided with a resistance element 541 and a resistance belt 5311, and the resistance element 541 and the resistance belt 5311 form a loop; the adjusting housing 531 drives the resistor 5311 to move relative to the resistor 541, so as to change the resistance of the resistor 5311 connected to the resistor. By detecting the resistance value of the resistor 5311 connected to the resistor, the rotation angle of the housing 531 can be detected and adjusted, and then the elasticity of the spring 533 and the friction force between the spring 533 and the friction plate group 534 can be calculated, so that a specific resistance value is generated for the user to check and reference.

After the user stretches the pull rope 7, the pull rope 7 needs to be automatically recovered, so that the user can conveniently operate the pull rope 7 next time, and therefore, the rope winding assembly 55 in the embodiment comprises a wire reel 551 and a spiral spring 552; the pull rope 7 is wound on the wire spool 551 and drives the wire spool 551 to rotate; the inner end of the spiral spring 552 is a fixed end, and the outer end is connected with the wire spool 551. When the pull rope 7 is stretched, the outer end of the scroll spring 552 is driven to rotate, so that the scroll spring 552 rotates to shrink and accumulate force, and when the pull rope 7 is loosened, the scroll spring 552 releases the elastic force to retract, and the pull rope 7 is retracted.

Since the pulling cord 7 cannot be forced by the user during the recovery process, if friction is generated between the spring 533 and the friction plate group 534 during the recovery of the pulling cord 7, the recovery of the pulling cord 7 is hindered. Therefore, the pull cord 7 needs to be recovered so that the friction plate set 534 does not rotate. For this purpose, in this embodiment, the rope winding assembly 55 is connected to the resistance base 56, and the resistance base 56 is fixedly connected to the friction plate set 534; the resistance base 56 is provided with a second ratchet 561, a ratchet cover 554 is arranged on one side of the rope winding assembly 55 facing the resistance base 56, and the ratchet cover 554 is provided with a second ratchet 5541 matched with the second ratchet 561, so that the resistance base 56 is in one-way linkage matched with the rope winding assembly 55 along the stretching direction of the pull rope 7. Thus, the rope winding assembly 55 can be ensured not to drive the friction plate group 534 to rotate relative to the spring 533 when the pull rope 7 is recovered, and smooth recovery of the pull rope 7 can be ensured.

Finally, the user may wish to see the calories expended during the workout to encourage the user to continue the workout. To achieve this function, a magnet is provided on the spool 551, and the magnet 5511 is mated with the fixedly provided hall PCB 57. The rotation angle and the cycle number of the wire spool 551 can be measured through the magnet 5511 and the Hall PCB 57 arranged on the wire spool 551, and then the extension amount and the extension time of the pull rope 7 are judged, and the calories consumed by a user in the pull rope 7 process can be calculated by combining the resistance value.

In order to facilitate users to view the information of consumed calories, resistance values and the like, the body-building device also comprises a display module 4 which is sleeved in the middle of the telescopic module 2.

In this embodiment, the foot pad module 3 includes an inner support seat 31, an outer support seat 32, and a rubber pad 33, wherein the inner support seat 31 is fixedly connected with the telescopic module 2, and the rubber pad 33 is disposed on one side of the outer support seat 32 away from the inner support seat 31; the inner support seat 31 and the outer support seat 32 are in reversing fit, so that the tensile force applied to the telescopic module 2 is reversed to the extrusion force of the outer support seat 32 towards the rubber pad 33. After the arrangement, when a user applies force to the telescopic module 2, the force is converted into the thrust of the inner supporting seat 31 to the outer supporting seat 32 through reversing fit, so that the extrusion force of the outer supporting seat 32 to the rubber pad 33 is increased. Thereby increasing the friction between the rubber pad 33 and the door frame or wall, and the magnitude of this friction increases as the magnitude of the force applied to the expansion module 2 by the user increases. The situation that the exercise equipment falls off due to excessive force of a user can be avoided.

Since friction is related to the roughness of the surface, it is independent of the size of the contact area. Therefore, the contact surface between the rubber pad 33 and the wall is further designed into a corrugated surface shape in the present embodiment, so as to increase the friction coefficient of the foot pad to the wall. The shape is helpful for increasing the adhesive force generated by extremely close contact of the surface of the foot pad and certain points of the surface of the wall body, and forming an adhesion mechanism, thereby increasing the friction force.

In this embodiment, the reversing engagement between the inner support seat 31 and the outer support seat 32 is an inclined surface 34, and the angle of the inclined surface is preferably 45 °. When the inner support seat 31 is stressed and moves radially, an acting force is applied to the sphere of the inner support seat 31 by the inclined surface, so that the pressure of the inner support seat 31 to the rubber pad 33 is increased, and the friction force between the rubber pad 33 and the wall body is increased; assuming that the tension of the single rod is 2G, the strength of the single-side foot pad is G; at this time, for the wall surface pressure Fn, fn=gtan θ. When θ >45 °, then there is Fn > G. Because the friction coefficient of the foot pad and the wall body is greater than 1, the friction force ff=mu.Fn > G (mu is the friction coefficient) is ensured that the friction force born by the inner supporting seat is greater than the tensile force born by the product no matter where the product is placed because the stress surface of the inner supporting seat is spherical, so that the product can be fixed on the wall surface.

The foregoing is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto, and any person skilled in the art will be able to make insubstantial modifications of the present utility model within the scope of the present utility model disclosed herein by this concept, which falls within the actions of invading the protection scope of the present utility model.
