Description

Technical Field

[0001] The present invention relates to the technical field of running training, and more specifically, to a safety protection device for running training. Background Art

[0002] Treadmill training is a popular indoor exercise method that uses an electric motor to drive the running belt to rotate continuously, allowing the trainee to run in an environment that is not restricted by weather, time and location. This method provides a convenient, safe and controllable training environment for running enthusiasts, but it should be noted that since the running belt of the treadmill is driven by a motor, the trainee is prone to fall and get injured if he or she steps unsteadily.

[0003] In the prior art, safety protection devices generally adopt the design of emergency stop devices and handrails. The main function of the emergency stop device is to quickly stop the treadmill in an emergency, thereby ensuring the safety of the user; while the handrails provide the necessary support for the runner to help maintain stability during running. However, in the actual training process, the trainee may not be able to activate the emergency stop device in time due to loss of balance, and may not be able to quickly hold the handrails, resulting in the risk of falling.

[0013] The beneficial effects of the present invention compared with the prior art are:

[0014] (1) The present invention adjusts the length of the strap unrolled from the reel, and the strap drives the reel to rotate on the screw rod, thereby adjusting the height of the reel from the treadmill. The torsion spring stores energy by twisting, so it can adapt to the heights of different trainees.

[0015] (2) When the trainee of the present invention tends to fall, the straps are driven to move quickly, so the winding drum rotates quickly, and the pin in the slide hole also rotates quickly. The pin is acted upon by centrifugal force, so that the pin moves in the slide hole in a direction away from the axis of the winding drum, that is, the pin is stuck in the limit groove. When the rotating drum stops rotating, the pin and the rotating seat body stop rotating, and the straps are no longer unrolled from the winding drum. At the same time, the auxiliary support belt supports the straps, and the straps hold the trainee's body to prevent the trainee from falling further.

[0016] (3) The present invention can increase the training intensity of the trainee through two tension components. When the trainee tends to fall, the rotating seat body drives the rotating drum to rotate synchronously, so the support plate 1 moves in the direction of the support plate 2, the spring 4 is compressed, the support plate 1 pulls the main pull rope to move, and then the power is transmitted through the support pull rope to pull the pressure pin out of the round hole of the sliding column. The spring 2 provides elastic force to drive the pressure plate to move upward along the sliding column. The square plate and the side of the pressure plate are no longer constrained by the pull plate, so the elastic rope no longer provides a tension load to the trainee, thereby ensuring the safety of the trainee.

[0017] (4) When the trainee's position changes in the present invention, the trainee will change the length of the strap unfolded on the reel, causing the reel to rise or fall in the screw rod. Therefore, the trainee will feel the change in the upward or downward pulling force of the strap. Therefore, the trainee can judge that the training position has changed, and thus actively adjust the training position to ensure safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] See also Figure 1-14 Structural schematic diagram, the present invention provides the following technical solutions:

[0035] A safety protection device for running training comprises a base plate 1, on which a treadmill 2 for running training is arranged. A trainee stands on the treadmill 2 for training. A column seat 3 is arranged on the base plate 1 and on one side of the treadmill 2. A central column 4 is vertically arranged at the center of the column seat 3. A screw rod 5 is vertically arranged above the central column 4. A swivel body 6 is arranged on the screw rod 5.

[0036] The rotating seat body 6 includes a winding drum 601, and the winding drum 601 forms a threaded fit with the screw rod 5. A strap 7 for tying up the trainee is wound on the winding drum 601. The strap 7 is continuously and evenly provided with a plurality of through holes 701. The strap 7 is provided with a locking assembly, and the locking assembly includes a fixing sleeve 12. The fixing sleeve 12 is provided with a slot 1201. The slot 1201 is sleeved on the strap 7. A latch 13 is slidably provided on the fixing sleeve 12. One end of the latch 13 is an inclined surface, and the other end of the latch 13 is provided with a pull plate 14. A spring 15 is provided on the outer sleeve of the latch 13, and the two ends of the spring 15 are respectively connected to the fixing sleeve 12 and the pull plate 14.

[0037] Specifically, the pull plate 14 is pulled and the spring 15 is stretched to make the pin 13 slide on the fixing sleeve 12, so that the pin 13 is disengaged from the slot 1201 of the fixing sleeve 12, and the strap 7 is inserted into the slot 1201, and then the strap 7 is wrapped around the trainee's waist, and then the tail of the strap 7 is inserted into the slot 1201 again, so that the through hole 701 of the strap 7 in the slot 1201 coincides with the pin 13, and the pull plate 14 is released. The spring 15 provides a pulling force to reinsert the pin 13 into the slot 1201, and the strap 7 can be tied around the trainee's waist.

[0038] The buckle assembly also includes a secondary sleeve 16 for fixing the tail of the strap 7. The secondary sleeve 16 is sleeved on the strap 7. The strap 7 is first inserted into the secondary sleeve 16, and then the strap 7 is tied around the trainee's waist, and the tail of the strap 7 is inserted into the secondary sleeve 16 to prevent the tail of the strap 7 from affecting the trainee.

[0039] A turntable 602 is provided below the winding drum 601, a slot 603 is provided on the side of the turntable 602, two sliding holes 604 are symmetrically provided on the side of the turntable 602 and located at the slot 603, the outer sleeve of the screw rod 5 is provided with a torsion spring 8, the two ends of the torsion spring 8 are respectively connected to the central column 4 and the turntable 602, and plug posts 9 are slidably provided in the two sliding holes 604, the two plug posts 9 are commonly connected with an elastic ring 10, and the elastic ring 10 is located in the slot 603; a rotating drum 11 is provided on the column seat 3, a cleaning rod 1101 for inserting the strap 7 is provided on the side of the rotating drum 11, and a limiting groove 1102 for clamping the plug post 9 is provided inside the rotating drum 11.

[0040] Specifically, the length of the strap 7 unfolded from the reel 601 is adjusted according to the height of the trainee. When the strap 7 is unfolded from the reel 601, the strap 7 drives the reel 601 to rotate on the screw rod 5, and the torsion spring 8 is twisted to store energy, thereby adjusting the height of the reel 601 from the treadmill 2, so that it can adapt to trainees of different heights. When the trainee tends to fall, the strap 7 drives the reel 601 to rotate rapidly because the trainee drives the strap 7 to move rapidly, and the rotating disk 602 rotates rapidly with the reel 601, and the plug 9 in the slide hole 604 also rotates rapidly. The plug 9 is acted upon by centrifugal force, so that the plug 9 moves in the slide hole 604 in the direction away from the axis of the reel 601, the elastic ring 10 stretches, and the plug 9 is inserted into the limit groove 1102, so that the plug 9 and the rotating seat body 6 no longer rotate, so the strap 7 is no longer unfolded from the reel 601, and the strap 7 pulls the trainee's body to prevent the trainee from falling further. When the binding belt 7 is loosened, the torsion spring 8 provides a torsional force to rotate the swivel body 6 to the original state, and the binding belt 7 is rewound onto the reel 601 .

[0041] When the trainee is training normally on the treadmill 2, since the running belt of the treadmill 2 is relatively narrow, once the trainee leaves the middle position of the treadmill 2, the trainee is at risk of a safety accident. At the same time, the trainee looks forward during training and it is difficult to observe whether the training position has changed. When the trainee's position changes, the trainee will change the length of the strap 7 on the winding drum 601, so that the winding drum 601 rises or falls in the screw 1 5, so the trainee will feel the change in the upward or downward pulling force of the strap 7, so the trainee can judge that the training position has changed, and actively adjust the training position to ensure safety.

[0042] The outer part of the central column 4 is rotatably provided with a rotating column 17, and the lower part of the turntable 602 of the rotating seat body 6 is vertically provided with four sliding rods 18, and the sliding rods 18 form a sliding fit with the rotating column 17; an auxiliary support cylinder 19 is provided on the base plate 1 and located on the other side of the treadmill 2, and a rotating column 20 is rotatably provided in the auxiliary support cylinder 19, and a transmission component 21 is provided between the sliding rod 18 and the rotating column 20, and one transmission wheel of the transmission component 21 is provided on the rotating column 17, and the other transmission wheel of the transmission component 21 is provided on the rotating column 20.

[0043] The transmission assembly 21 is composed of two transmission wheels and a transmission belt. When one rotating wheel rotates, power is transmitted through the transmission belt to make the other transmission wheel rotate synchronously.

[0044] The rotating column 20 is provided with a screw rod 22, and the screw rod 22 is provided with a nut plate 23, and the screw rod 22 and the nut plate 23 form a threaded fit, the side of the nut plate 23 is provided with a side plate 24, and the middle of the side plate 24 is provided with a slider 25, the side of the auxiliary support cylinder 19 is provided with a slide groove 1901 for inserting the side plate 24, and the slider 25 is slidably arranged on the slide groove 1901, the side plate 24 is provided with a frame 26, and an auxiliary support belt 27 is provided between the frame 26 and the strap 7, one end of the auxiliary support belt 27 is buckled on the frame 26, and one end of the auxiliary support belt 27 is provided with a frame 28 for inserting the strap 7.

[0045] Specifically, when the swivel body 6 rotates, power is transmitted through the four sliding rods 18, so that the rotating column 17 rotates synchronously on the central column 4, and power is transmitted through the transmission component 21 to drive the rotating column 20 to rotate synchronously. The rotating column 20 drives the screw 22 to rotate, thereby driving the nut plate 23 to move up and down, and the nut plate 23 and the swivel body 6 are kept at the same height. The strap 7 is supported by the auxiliary support belt 27. Therefore, when the trainee is at risk of falling, the strap 7 can better support the training and prevent the trainee from falling.

[0046] Taking into account that when the trainee is training on the treadmill 2, in order to increase the training intensity and the load on the legs, a square plate 29 is provided on the base plate 1 and at the tail of the treadmill 2, and two groups of tension components are provided above the square plate 29. The tension component includes a fixed pin 30, and the fixed pin 30 is placed above the square plate 29. A pulling plate 31 is provided at one end of the square plate 29, and the pulling plate 31 contacts the side of the square plate 29. An elastic rope 32 is provided at the other end of the fixed pin 30, and a foot ring 33 for increasing the weight is provided at the end of the elastic rope 32.

[0047] Two sliding columns 34 are vertically provided above the square plate 29, and circular holes are provided on the sliding columns 34. A pressure plate 35 is slidably provided on the two sliding columns 34 together, and the pressure plate 35 presses the upper surface of the fixed pin 30, and the pulling plate 31 contacts the side of the pressure plate 35. A spring 2 36 is provided on the outer sleeve of the sliding column 34, and the two ends of the spring 2 36 are respectively connected to the square plate 29 and the pressure plate 35. A sliding seat 37 is provided on the pressure plate 35 and located on the side of the sliding column 34. A pressing pin 38 is slidably provided on the sliding seat 37, and the head of the pressing pin 38 is inserted into the circular hole of the sliding column 34. A spring 39 is provided on the outer sleeve of the pressing pin 38, and the two ends of the spring 39 are respectively connected to the sliding seat 37 and the pressing pin 38.

[0048] The tail of the pressing pin 38 is connected to a support rope 40, and a guide wheel 41 for guiding the support rope 40 is rotatably provided on the pressing plate 35. The two support ropes 40 are commonly connected to a main pull rope 42. A guide column 43 for guiding the main pull rope 42 is provided on the bottom plate 1. The tail of the main pull rope 42 is connected to a support plate 1 44. The support plate 1 44 is fixed on the rotating drum 11, and the rotating drum 11 is rotatably provided in the column seat 3. A support plate 2 45 is commonly provided on the side of the column seat 3 and at the same height as the support plate 1 44. A spring 46 is provided between the support plate 1 44 and the support plate 2 45.

[0049] Specifically, the fixed pins 30 of the two tensioning components are placed on the square plate 29, and the pressing plate 35 is pressed on the upper surface of the fixed pin 30, the second spring 36 is in a compressed state, and the third spring 39 provides elastic force, so that the pressing pin 38 is inserted into the round hole of the sliding column 34, so that the pressing plate 35 is kept in contact with the upper surface of the fixed pin 30, and the pulling plate 31 is in contact with the side of the square plate 29 and the pressing plate 35 at the same time, blocking the fixed pin 30 and the pulling plate 31 from moving toward the treadmill 2. When the trainer trains on the treadmill 2, the two foot rings 33 are put on the feet of the trainer, so the trainer can increase the intensity of training. When the plug post 9 is inserted into the limit groove 1102, power is transmitted through the plug post 9, and the rotating seat body 6 drives the rotating drum 11 to rotate synchronously, so the support plate 1 44 moves in the direction of the support plate 2 45, the spring 46 is compressed, and the support plate 1 44 pulls the main pull rope 42 to move, and then the power is transmitted through the support pull rope 40 to pull the pressing pin 38 out of the round hole of the sliding column 34. The spring 2 36 provides elastic force to drive the pressing plate 35 to move upward along the sliding column 34. The square plate 29 and the side of the pressing plate 35 are no longer constrained by the pulling plate 31, so the elastic rope 32 no longer provides a tensile load to the trainee, thereby ensuring the safety of the trainee.

[0050] Working principle: Before training, the trainee places the fixed pins 30 of the two tension components on the square plate 29, and presses the pressure plate 35 on the upper surface of the fixed pin 30. The spring two 36 is in a compressed state, and the spring three 39 provides elastic force to insert the pressure pin 38 into the round hole of the sliding column 34, so that the pressure plate 35 keeps in contact with the upper surface of the fixed pin 30. The pulling plate 31 is in contact with the side of the square plate 29 and the pressure plate 35 at the same time, blocking the fixed pin 30 and the pulling plate 31 from moving toward the treadmill 2. The trainee puts the two foot rings 33 on the trainee's feet, so the trainee can increase the intensity of training. Afterwards, the trainee adjusts the length of the strap 7 unrolled from the winding drum 601, and the strap 7 drives the winding drum 601 to rotate on the screw rod 5, thereby adjusting the height of the winding drum 601 from the treadmill 2. The torsion spring 8 twists and stores energy, so it can adapt to the height of the trainee, pulls the pull plate 14, and the spring 15 stretches to make the pin 13 slide on the fixing sleeve 12, even if the pin 13 is disengaged from the slot 1201 of the fixing sleeve 12, the strap 7 is inserted into the slot 1201, and then the strap 7 is wrapped around the trainee's waist, and then the tail of the strap 7 is inserted into the slot 1201 again, so that the through hole 701 of the strap 7 in the slot 1201 coincides with the pin 13, and the pull plate 14 is released. The tension provided by the spring 15 is used to reinsert the pin 13 into the slot 1201, and the strap 7 can be tied around the trainee's waist. When the swivel body 6 rotates, power is transmitted through the four sliding rods 18, so that the rotating column 17 rotates synchronously on the central column 4, and power is transmitted through the transmission component 21, driving the rotating column 20 to rotate synchronously. The rotating column 20 drives the screw 22 to rotate, thereby driving the nut plate 23 to move up and down, and the nut plate 23 and the swivel body 6 maintain the same height.

[0051] When the trainee tends to fall, the trainee drives the strap 7 to move quickly, so the strap 7 drives the winding drum 601 to rotate quickly, the turntable 602 rotates synchronously with the winding drum 601, and the plug post 9 in the slide hole 604 also rotates quickly. The plug post 9 is acted upon by the centrifugal force, so that the plug post 9 moves in the slide hole 604 in the direction away from the axis of the winding drum 601, the elastic ring 10 stretches, and the plug post 9 is inserted into the limit groove 1102. The power is transmitted through the plug post 9, and the rotating seat body 6 drives The rotating drum 11 rotates synchronously, so the support plate 1 44 moves in the direction of the support plate 2 45, the spring 46 is compressed, the support plate 1 44 pulls the main pull rope 42 to move, and then transmits power through the support pull rope 40 to pull the pressing pin 38 out of the round hole of the sliding column 34. The spring 2 36 provides elastic force to drive the pressing plate 35 to move upward along the sliding column 34. The square plate 29 and the side of the pressing plate 35 are no longer constrained by the pulling plate 31, so the elastic rope 32 no longer provides a tensile load to the trainee, thereby ensuring the safety of the trainee.

[0052] After the spring four 46 is compressed, the rotating drum 11 no longer rotates. Since the plug post 9 is stuck in the limit groove 1102, the plug post 9 and the rotating seat body 6 no longer rotate, and the strap 7 no longer unfolds from the winding drum 601. At the same time, the auxiliary support belt 27 supports the strap 7, and the strap 7 pulls the trainee's body to prevent the trainee from falling further.

[0053] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
