Description

Technical Field

[0001] The utility model belongs to the technical field of protective devices, in particular to a protective device for fitness equipment. Background Art

[0002] Fitness equipment is often divided into two categories according to the number of training functions: single-function and comprehensive multi-function. Commonly used ones include bench press racks, rowing machines, fitness bikes, steppers, treadmills, waist beautification machines, etc. In the existing technology, when users use bench press racks for exercise, it is easy for the barbell to fall out of their hands due to exhaustion. The falling barbell can easily injure the user. Usually, users will ask their partners to help protect them, but human protection is not in place, and even the protector may be injured. Therefore, there is a need for a protective device for fitness equipment that can provide safety protection against unexpected situations.

[0003] A Chinese patent with authorization announcement number CN218129753U discloses a protective device for fitness equipment, which belongs to the technical field of protective devices.

[0004] However, the above has the following shortcomings:

[0005] 1. According to the description in the above patent, the barbell is supported only by the support plate, and the two ends of the barbell cannot be limited. When exercising without a companion, the athlete will not be able to support the barbell normally when he loses strength, resulting in the push-up action being skewed, causing the barbell to be unable to be supported by the support plate in an ideal state, posing a danger to the athlete's life safety.

[0006] 2. The above patent only provides idealized safety protection and does not take into account the situation where the athlete lacks experience, resulting in poor lifting movements, causing the athlete to lift the barbell beyond the protection range of the protective device in the above patent, making the protective device in the above patent unable to play a protective role. Utility Model Content

[0007] In order to overcome the deficiencies of the prior art, the utility model solves the technical problem of limiting the moving direction of the barbell by setting a limiting moving rod, so that the barbell can only move within the range of the support frame, and limiting the length of the limiting block, so that the pushing posture of the athlete is corrected, and the locking protection device connected to the limiting moving rod protects the safety of the athlete in real time, thereby improving the protection range and the safety of the protected.

[0008] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a protective device for fitness equipment, comprising a base frame and a limit frame, wherein the surface of the base frame is symmetrically distributed and fixedly connected to two support frames, a support cross frame is fixedly connected between the two support frames, each support frame surface is movably connected to the limit frame, each limit frame surface is detachably connected to the limit ring, each limit frame is provided with an extension block 2 at one end of the limit ring, a fixing rod is fixedly connected in each extension block 2, a protective belt is fixedly connected to the surface of each fixed rod, a threaded groove is provided in each limiting ring, a hand wheel is fixedly connected to the surface of each limiting ring, and the other end of each protective belt is fixedly connected to a locking protection device.

[0011] Furthermore, one end of a protective belt is fixedly connected to the surface of each ratchet gear frame, and the other end of each protective belt is fixedly connected to a limiting device. A limiting groove is provided in the movable limiting gear.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, a protective device for fitness equipment includes a base frame 10, two support frames 11 are symmetrically distributed and fixedly connected on the surface of the base frame 10, a reclining bench 12 is fixedly connected to the surface of the base frame 10 between the two support frames 11, a supporting cross frame 16 is fixedly connected to the surface between the two support frames 11, and a fixed bracket 23 is fixedly connected to the surface of each support frame 11 below the supporting cross frame 16.

[0028] The fixed bracket 23 is provided so that the barbell can be supported on the fixed bracket 23 when not in use, thereby ensuring the normal operation of the fitness device.

[0029] like Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 8As shown, the lower end surface of each support frame 11 is provided with an extension block three 26, and the surface of each extension block three 26 is fixedly connected to a fixing plate one 27. The surface of each support frame 11 is fixedly connected to a fixing plate three 40 at the position of the fixing plate one 27. A protection device box 13 is fixedly connected between each fixing plate one 27 and the fixing plate three 40 at the corresponding position. The surface of each protection device box 13 is fixedly connected to a ratchet gear frame 29 between the fixing plates one 27. Ratchets are evenly distributed in each ratchet gear frame 29. A movable limiting gear 30 is movably connected in each ratchet gear frame 29. A plurality of ratchet teeth 41 are evenly provided on the surface of the movable limiting gear 30. A limiting groove 32 is eccentrically provided in the movable limiting gear 30. The surface of the protection device box 13 is located at the center of the ratchet gear frame 29 and passes through the protection device box 13 and is rotatably connected. 9. The surface of the rotating rod 39 is fixedly connected with a rotating block 31, and the rotating block 31 is transmission-connected to the movable limiting gear 30. When the rotating block 31 rotates rapidly, the eccentric movement of the movable limiting gear 30 causes the rotating block 31 to enter the limiting groove 32, so that the ratchet 41 engages with the ratchet in the ratchet gear frame 29. The surface of each rotating rod 39 located in the protection device box 13 is fixedly connected with one end of the protective belt 14, and the surface of each protection device box 13 is fixedly connected with a fixed limiting block 36 located in the fixed plate three 40. One end of a spring coil 35 is fixedly connected between each fixed limiting block 36, and the center of each spring coil 35 is fixedly connected to the rotating rod 39 at the corresponding position. Each fixed plate one 27 is fixedly connected to the upper end of the fixed plate three 40 at the corresponding position with a fixed plate two 33, and an avoidance groove 34 is provided on the surface of the fixed plate two 33.

[0030] By eccentrically setting the movable limiting gear 30, when the rotating block 31 drives the movable limiting gear 30 to rotate rapidly, the ratchet 41 on the surface of the movable limiting gear 30 engages with the ratchet in the ratchet gear frame 29 to achieve a locking effect, stopping the extension of the protective belt 14 and providing safety protection. By setting the spring coil 35, the protective belt 14 can be reeled in by the rotating rod 39 when it is in a relaxed state.

[0031] like Figure 1 、 Figure 3 、 Figure 4 and Figure 7 As shown, the surface of each support frame 11 is located above the fixed bracket 23 and is movably connected to the limiting frame 24. A slide groove 22 is provided on the surface of each support frame 11. A slide rod 21 is slidably connected in each slide groove 22. A slide groove 25 is provided on the surface of each limiting frame 24. Each slide rod 21 is slidably connected in the slide groove 25. An extension block 21 is provided on the surface of the limiting frame 24. A fixed rod 28 is fixedly connected in the extension block 219. The other end of each protective belt 14 is fixedly connected to the surface of the fixed rod 28. The surface of each limiting frame 24 is slidably connected to the limiting ring 20 near the extension block 219. A threaded groove 37 is provided in the limiting ring 20. The surface of the limiting ring 20 is fixedly connected to the hand wheel 38.

[0032] By setting the limit ring 20, the limit frame 24 and the barbell bar are connected. By limiting the moving direction and range of the limit frame 24, the barbell bar will not be skewed or offset, and the athlete can exercise normally. By connecting with the protective belt 14 through the fixed rod 28, the athlete can be in a protected state in real time during exercise.

[0033] like Figure 1 and Figure 3 As shown, an extension block 15 is provided on the top of the support frame 11, and a rotating shaft 17 is rotatably connected inside the extension block 15. A pulley 18 is fixedly connected to the surface of the rotating shaft 17, and the surface of the pulley 18 passes around the protective belt 14.

[0034] By providing the pulley 18 , direct friction between the protective belt 14 and the device is reduced, the loss of the protective belt 14 is reduced, and the durability of the device is improved.

[0035] In this embodiment, initially, the athlete connects one end of each protective belt 14 to the rotating rod 39 at the corresponding position, passes through the avoidance groove 34 on the surface of the fixed plate 2 33 at the corresponding position, and then passes each protective belt 14 around the surface of the pulley 18 at the corresponding position from above, and connects the other end of each protective belt 14 to the surface of the fixed rod 28 in the extension block 2 19. At this time, since the protective belt 14 is in a stretched state, the rotating rod 39 rotates. Due to the rotation of the rotating rod 39, the spring coil 35 on the surface of the rotating rod 39 rotates. Under the restriction of the fixed limit block 36, the spring coil 35 rotates to accumulate elasticity.

[0036] Before use, the athlete places the barbell on the surface of the fixed bracket 23, adds enough barbell plates, lifts the limit frames 24 at both ends, and rotates the limit rings 20 by rotating the hand wheels 38 at both ends of the barbell, so that the two ends of the barbell are fixed in the limit frames 24 at the corresponding positions.

[0037] During use, the athlete lies flat on the surface of the reclining bench 12, extends his head from under the supporting cross frame 16, and on the same side as the protective device box 13, reaches out to remove the barbell from the surface of the fixed bracket 23. Since the surface of the supporting frame 11 is provided with a slide groove 1 22, and the surface of the limiting frame 24 is provided with a slide groove 25, the barbell has sufficient freedom, so that the barbell can be easily removed from the surface of the fixed bracket 23 and avoid the position where the fixed bracket 23 is located.

[0038] During the exercise, since the push-up exercise requires the barbell to be pushed and retracted slowly, when the athlete pushes the barbell, the limit frame 24 is lifted along with the barbell, causing the fixed rod 28 in the extension block 2 19 at one end of the limit frame 24 to be lifted, so that the protective belt 14 is in a relaxed state. At this time, the spring coil 35 is not under force and releases its elasticity, causing the rotating rod 39 to rotate in the opposite direction, causing the protective belt 14 on the surface of the rotating rod 39 to be reeled up, so that the protective belt 14 is in a taut state again. When pushed slowly, when the rotating rod 39 rotates, the rotating block 31 condensed on the surface of the rotating rod 39 slowly pushes the movable limit gear 30 to rotate, and the movable limit gear 30 makes a circular motion along the axis direction of the rotating block 31. The fixed plate 3 40 on the surface of the movable limit gear 30 will not engage with the ratchet in the ratchet gear frame 29, and the device can be used normally.

[0039] When the athlete stops pushing the barbell and performs a recovery movement, as the barbell moves downward, the limit frame 24 moves downward synchronously, so that the fixed rod 28 in the extension block 219 on the surface of the limit frame 24 pulls the protective belt 14, so that the protective belt 14 is in a taut state and is subjected to the tension of the fixed rod 28, so that the protective belt 14 on the surface of the rotating rod 39 drives the rotating rod 39 to rotate, so that the rotating rod 39 rotates the spring coil 35, so that the spring coil 35 accumulates elasticity, and at this time the athlete still recovers the barbell slowly, the movable limit gear 30 still performs a circular motion, and the device still works normally.

[0040] When the athlete loses strength and can no longer push the barbell, the barbell loses the athlete's pushing force and falls rapidly. At this time, the limit ring 20 connected to the end of the barbell drives the limit frame 24 to fall rapidly, so that the fixed rod 28 moves downward rapidly, so that the protective belt 14 stretches rapidly, so that the rotating rod 39 connected to the protective belt 14 rotates rapidly, so that the rotating block 31 rotates rapidly, and drives the movable limit gear 30 to rotate. However, since the movable limit gear 30 is eccentrically set, when it moves rapidly again, the movable limit gear 30 is centrifugal. The gear 30 is offset, causing the rotating block 31 to be stuck in the limiting groove 32, and due to the eccentric movement of the movable limiting gear 30, the fixed plate 3 40 on the surface of the movable limiting gear 30 engages with the ratchet in the ratchet gear frame 29, making the movable limiting gear 30 unable to move, so that the position of the rotating block 31 transmitted in the limiting groove 32 set in the movable limiting gear 30 is fixed, so that the rotating rod 39 no longer rotates, the protective belt 14 stops moving, the fixed rod 28 stops falling, and the barbell bar stops falling, thereby achieving the effect of protecting the athletes.

[0041] When an athlete loses strength, the barbell bar is prone to uneven force and shifting. However, under the restriction of the limit frame 24, the barbell bar cannot shift, so that the barbell bar can maintain movement in the area between the two support frames 11, so that the barbell bar is always in a state of being restricted by the protective device, so that the athlete is always protected.

[0042] When the athlete leaves the dangerous area where the barbell bar falls, the athlete puts the barbell bar back on the surface of the two fixed brackets 23, rotates the hand wheel 38 to release the lock of the limit ring 20 on the barbell bar, and then removes the barbell plates on the barbell bar to complete the bench press exercise.

[0043] The above-mentioned protective belt 14 and spring ring 35 are both existing mature technologies and will not be described in detail herein.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction.
