DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Reference Figure 1-Figure 7 The present invention provides a protective device for indoor sports and fitness equipment, comprising:

[0042] A flat bed 1, with support frames respectively arranged on both sides of the flat bed 1, a support assembly arranged on the support frame, a first pressure sensor 2 arranged at the bottom end of the flat bed 1, the first pressure sensor 2 is used to obtain a pressure signal of the flat bed 1 along the vertical direction, the first pressure sensor 2 is communicatively connected with the support assembly, when the pressure of the flat bed 1 is tilted, the support end of the support assembly is lifted in the vertical direction to support the barbell;

[0043] At least one pair of hooks 3, movably connected to both sides above the flat board 1, for hanging a barbell;

[0044] The locking mechanism includes a locking shaft 4, which is connected to the support frame. A strap 5 is wound around the locking shaft 4. The end of the strap 5 away from the locking shaft 4 is fixed to the hook 3. A locking assembly is provided on the support frame. The locking end of the locking assembly is connected to the locking shaft 4. When the strap 5 is separated from the locking shaft 4 in a stalled state, the locking shaft 4 is fixed to the support frame.

[0045] The present invention arranges support frames on both sides of the supine board 1, and arranges a liftable support assembly on the support frame. Only when the pressure signal of the supine board 1 obtained by the first pressure sensor 2 is offset, the support end of the support assembly is lifted to support the barbell, thereby ensuring that the person on the supine board 1 can perform bench press fitness training normally and ensuring the safety of the person. In addition, by movably connecting the hook 3 on the supine board 1, the hook 3 is used to pull the barbell, and the hook 3 is fixed by the strap 5 wound around the locking shaft 4. When the person performs bench press training, the barbell pulls the hook 3 and the strap 5. If the barbell slips out of the hand or the person loses strength, the barbell falls rapidly. The stall state of the strap 5 is detected by the locking assembly, and the locking shaft 4 is fixed when the strap 5 is quickly pulled out, thereby stabilizing the barbell, thereby improving the safety of the bench press training protection for the person.

[0046] Specifically, the locking assembly cooperates with the strap 5 to imitate the structural principle of a safety belt to provide safety protection for the barbell and prevent the barbell from causing damage to personnel due to rapid falling.

[0047] And because people need to maintain balanced support on both sides of the barbell during bench press training, the signal of the pressure inclination of the supine board 1 can be obtained through the first pressure sensor 2, so as to judge whether the person has lost control or the barbell has detached. At this time, the straps 5 and the hooks 3 can quickly fix the barbell, and at the same time, the supporting end of the supporting assembly is lifted to provide stable support for the barbell, which can improve the safety of bench press training.

[0048] Furthermore, it also includes:

[0049] The mounting plate 6 is arranged on the support frame, and a moving component is arranged on the support frame, and the moving end of the moving component is connected to the mounting plate 6;

[0050] The locking shell 7 is fixedly connected to the mounting plate 6, and the locking shaft 4 is transferred into the locking shell 7. The second pressure sensor 9 and the first servo motor 8 are respectively fixedly connected to the two sides of the locking shell 7. The second pressure sensor 9 and the first servo motor 8 are both connected to the locking shaft 4, and the second pressure sensor 9 is communicatively connected to the first servo motor 8. Only when the pressure on the strap 5 is zero, the first servo motor 8 cooperates with the locking shaft 4 to reel up the strap 5.

[0051] The second pressure sensor 9 is connected to the first servo motor 8 for communication, and the second pressure sensor 9 obtains the pressure signal of the locking shaft 4. When the person bench presses down, the strap 5 smoothly extends out of the locking shell 7, and the strap 5 transmits a pressure signal of pulling the barbell. The first servo motor 8 is turned off, and the locking shaft 4 rotates with the pulling of the strap 5. When the person bench presses up, the pressure on the strap 5 is zero. At this time, the first servo motor 8 is started and the locking shaft 4 is rotated in the opposite direction to reel in the strap 5, which can make the hook 3 move synchronously with the barbell and prevent the first servo motor 8 from providing an upward pulling force that affects the effect of the person's bench press training.

[0052] Specifically, the strap 5 is made of common nylon material and has sufficient structural strength to support the barbell.

[0053] Further, the locking assembly includes:

[0054] The locking ring 10 is fixedly connected in the locking housing 7, and a ratchet groove is provided on the inner ring side of the locking ring 10;

[0055] The connecting ring 11 is sleeved and fixedly connected to the outside of the locking shaft 4, and the connecting ring 11 is transferred to the inner ring side of the locking ring 10;

[0056] The pawl 12 and the connecting ring 11 are fixedly connected with a fixing seat 14 on the outer peripheral side, the fixing seat 14 is provided with a groove, a rotating rod 13 is connected in the groove, one end of the pawl 12 is fixedly connected to the side wall of the rotating rod 13, a torsion spring 15 is wound around the rotating rod 13, and the two ends of the torsion spring 15 are respectively fixedly connected to the pawl 12 and the fixing seat 14.

[0057] The pawl 12 is elastically abutted against the outer peripheral side of the connecting ring 11 by the torsion spring 15. When the barbell slips out of the hand or the person loses strength, the barbell falls rapidly, the strap 5 pulls the locking shaft 4 to rotate at high speed, and the centrifugal force generated by the rotation of the connecting ring 11 throws the pawl 12 out, and the pawl 12 is engaged with the ratchet groove of the locking ring 10, thereby fixing the locking shaft 4, achieving rapid support for the barbell and improving the safety of the fitness equipment.

[0058] Specifically, the hook 3 is made of metal elastic material, and is tightly connected to the barbell bar by buckling with the barbell bar.

[0059] Furthermore, a plurality of ratchet claws 12 are provided, and the plurality of ratchet claws 12 are distributed at equal intervals along the circumference of the connecting ring 11 .

[0060] The stability of locking and fixing the locking shaft 4 is improved by using a plurality of ratchet claws 12 distributed at equal intervals in the circumferential direction.

[0061] Furthermore, the mobile component includes:

[0062] The first cylinder 16 is fixed to the top surface of the support frame, the piston rod of the first cylinder 16 is fixed to the second cylinder 17 in the vertical direction, and the second cylinder 17 extends along the length direction of the horizontal board 1, and the mounting plate 6 is fixed to the side of the piston rod of the second cylinder 17 close to the horizontal board 1;

[0063] The base 18 is fixedly connected to the top surface of the mounting plate 6 , and the locking housing 7 is fixedly connected to a hollow groove provided on the top surface of the base 18 .

[0064] The second cylinder 17 is lifted by the first cylinder 16, and the second cylinder 17 drives the mounting plate 6 to move along the length direction of the horizontal board 1, so that the locking shell 7 can correspond to the position of the bench press barbell of different people.

[0065] A reinforcing rod 19 is fixedly connected between the second cylinder 17 and the first cylinder 16 to provide structural strength for the barbell support.

[0066] Furthermore, the support frame includes a top plate 20, which is located on one side of the flat board 1 near the front end. Fixed rods 21 are respectively fixed to both ends of the top plate 20. The bottom ends of the fixed rods 21 extend vertically downward. The top surface height of the top plate 20 is the same as that of the flat board 1. A support groove is opened on the top surface of the top plate 20, and the support assembly is arranged in the support groove.

[0067] By controlling the height of the top plate 20 to be the same as that of the flat bench 1, it is avoided that the barbell is directly supported, which would affect the normal bench press training of the personnel.

[0068] Furthermore, the support assembly includes:

[0069] The support plate 22 has one end connected in the support groove through the rotating shaft 24. A second servo motor 23 is fixedly connected to one side of the top plate 20. The output shaft of the second servo motor 23 is coaxially fixedly connected to the rotating shaft 24. The first pressure sensor 2 is connected to the second servo motor 23 in communication.

[0070] One end of the third cylinder 25 is hinged to the inner wall of the bottom end of the support groove, and the other end of the third cylinder 25 extends obliquely upward and is hinged to the bottom surface of the support plate 22 .

[0071] The pressure signal of the horizontal plate 1 is obtained through the first pressure sensor 2. When the pressure is offset, the second servo motor 23 is started to drive the rotating shaft 24 to rotate, so that the support plate 22 rotates and extends out of the support groove. At the same time, the third cylinder 25 supports the bottom end of the support plate 22 to improve the support strength and support stability of the support plate 22.

[0072] Furthermore, a plurality of slots are formed on the top surface of the support plate 22 , and the plurality of slots are evenly spaced along the axis direction of the support plate 22 .

[0073] The barbell bar is installed and fixed through several slots, and the barbell is supported and fixed in time according to different heights to ensure the safety of the bench press personnel.

[0074] Furthermore, a pressure rod 26 is fixedly connected to the bottom end of the front end of the horizontal board 1, and a telescopic rod 27 is slidably connected to the bottom end of the pressure rod 26. The bottom end of the telescopic rod 27 is against the ground, and a first pressure sensor 2 is arranged between the telescopic rod 27 and the pressure rod 26.

[0075] Pressure rods 26 are fixedly connected on both sides of the center symmetry of the flat board 1, and telescopic rods 27 are slidably connected at the bottom ends of the pressure rods 26. The bottom ends of the telescopic rods 27 are abutted against the ground to obtain the pressure signal of the flat board 1 in the vertical direction. When an accident occurs, the barbell tilts along one side of the person, resulting in inconsistent pressure signals obtained on both sides of the flat board 1. The pressure signal is detected through an external control system, and then the second servo motor 23 and the third cylinder 25 are started to support the barbell.

[0076] Specifically, the external control system is a common signal transceiver and processor, which receives and compares the pressure signals on both sides of the horizontal board 1. When the pressure signal deviation between the two is large, it can be determined that an accident of the barbell falling has occurred. At this time, the processor generates an electrical signal to start the second servo motor 23 and the third cylinder 25, and rotates and lifts the support plate 22 to support the barbell.

[0077] Furthermore, it also includes:

[0078] The barbell rack 28 is placed at the front end of the supine board 1. A plurality of support seats 29 are fixedly connected to the barbell rack 28 on one side close to the supine board 1 in the vertical direction. The top ends of the support seats 29 are provided with support grooves.

[0079] The working principle of the indoor sports fitness equipment protective device of the present invention is as follows:

[0080] When a person performs bench press training, he lies flat on the flat board 1 with his head facing the barbell rack 28, first hangs the hook 3 on the barbell bar, and then takes the barbell off the barbell rack 28 to perform bench press training.

[0081] When a person loses strength or the barbell slips, the barbell falls rapidly, pulling the strap 5 to rotate the locking shaft 4 at high speed. The locking shaft 4 drives the connecting ring 11 to rotate. The centrifugal force generated by the high-speed rotation rotates the pawl 12 elastically squeezed by the torsion spring 15 to extend out of the connecting ring 11, and the pawl 12 is directly engaged with the ratchet groove of the locking ring 10, thereby fixing the locking shaft 4, and the strap 5 and the hook 3 are pulled and fixed to the barbell.

[0082] At the same time, after the barbell is released from the hand, the first pressure sensor 2 at the bottom end of the supine board 1 obtains the pressure signal changes on both sides of the supine board 1, thereby starting the second servo motor 23 and the third cylinder 25, rotating and lifting the support plate 22, stably supporting the barbell, and realizing efficient protection of personnel.

[0083] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0084] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
