Abstract
Description
Technical Field
[0001] This invention relates to the field of tensile training device technology, specifically a simple tensile physical fitness training device for public security. Background Technology
[0002] Physical fitness is the ability to adapt to the external environment, mainly including the ability to enjoy activities and adapt to unexpected situations.
[0003] Considering that police physical training requires training in multiple physical abilities, and that pulling is a relatively important training category, it is necessary to use pulling equipment for auxiliary training during the pulling training process. Therefore, some pulling physical training devices with special structures and functions can be applied.
[0004] Traditional resistance training devices typically consist of a central elastic rope with handles at both ends. To use it, the user places their foot on the middle of the rope and then pulls on it with both arms. The length of the pull is controlled by the angle at which the user's legs are spread. This method can cause excessive strain for shorter individuals, leading to fatigue. Furthermore, controlling the rope length based on the leg angle causes the rope to compress the sides of the shoes, resulting in dents and damage over time, as well as foot discomfort. During resistance training, if the user loses control, the handles will move rapidly downwards under the force of the elastic rope, potentially striking the user's legs or feet and causing injury, making the process extremely inconvenient.
[0005] In summary, a simple tension physical training device for public security personnel needs to be proposed to solve the above problems. Summary of the Invention

[0046] The anti-detachment pull ring structure 5 consists of two anti-detachment pull ring structures 5, which are installed at the ends of the two elastic pull ropes 2 away from the adjustment and fixing structure 4.
[0047] With the fixed base plate 1 in place, there is no need to directly fix the elastic rope 2 with the feet. At the same time, the foot can be limited by the fixed base plate 1 through the disassembly and assembly limiting structure 3, which prevents it from detaching during the resistance training. The length of the elastic rope 2 can be adjusted and further fixed by the adjusting fixing structure 4. During the resistance training, the arc-shaped contact plate 48 prevents the elastic rope 2 from causing marks or damage to the feet. With the anti-detachment pull ring structure 5, the elastic rope 2 and the auxiliary pull block 51 can be disassembled and assembled. At the same time, with the elastic rope 2 and the fixing strap 510, the auxiliary pull block 51 can be fixed to the wrist and other parts of the body, which can prevent injury from the auxiliary pull block 51 after detachment.
[0048] refer to Figure 4 The disassembly and assembly limiting structure 3 also includes a rectangular locking frame 31 installed on the top of the outer surface of the fixed base plate 1 near the middle position. A rectangular locking block 32 is locked in the inner wall of the rectangular locking frame 31. First insertion holes 33 are opened on the inner walls of both sides of the rectangular locking frame 31. Second insertion holes 34 are opened on the inner wall of the rectangular locking block 32. Threaded rods 35 are inserted into the inner walls of the first insertion holes 33 and the second insertion holes 34. A fixing nut 36 is threadedly connected to one end of the outer surface of the threaded rod 35.
[0049] By setting rectangular locking blocks 32 and rectangular locking frames 31, the connecting rectangular block 37 can be fixed to the fixed base plate 1. Under the action of the threaded insertion rod 35, it can cooperate with the second insertion hole 34 on the rectangular locking block 32 and the first insertion hole 33 on the rectangular locking frame 31 for auxiliary fixing, thereby preventing the connecting rectangular block 37 from separating from the fixed base plate 1.
[0050] refer to Figure 5 A connecting rectangular block 37 is fixedly connected to the top of the outer surface of the rectangular positioning block 32. Two U-shaped frames 38 are symmetrically fixedly connected to the two sides of the outer surface of the connecting rectangular block 37. A rotating rod 39 is rotatably connected between the two sides of the inner wall of the U-shaped frame 38. A rotating round block 310 is fixedly connected to the outer surface of the rotating rod 39. An arc-shaped pressure plate 311 is fixedly connected to the outer surface of the rotating round block 310.
[0051] By setting a rotating rod 39 and a rotating block 310, the rotating rod 39 can drive the rotating block 310 to rotate, which in turn can drive the arc-shaped pressure plate 311 to rotate, so that the arc-shaped pressure plate 311 can fit against the foot surface, thereby limiting the distance between the foot surface and the fixed base plate 1.
[0052] refer to Figure 5 One end of the rotating rod 39 passes through the inner wall of the U-shaped frame 38 and is fixedly connected to the operating block 312. The inner wall of the operating block 312 is inserted with a locking rod 313. A number of locking holes 314 are opened on one side of the inner wall of the U-shaped frame 38. The number of locking holes 314 are arranged in an equidistant circle. The outer surface of the locking rod 313 can be detachably locked with the inner wall of the locking hole 314.
[0053] By setting the locking rod 313 and the locking hole 314, the locking rod 313 can be locked into the inner wall of the locking hole 314, thereby assisting in fixing the operating block 312, and thus assisting in fixing the rotating rod 39 and the rotating block 310.
[0054] Through the above scheme, in the specific use process, the rectangular locking block 32 is inserted into the inner wall of the rectangular locking frame 31, and then the threaded rod 35 is inserted into the first insertion hole 33 and the second insertion hole 34. At this time, the fixing nut 36 is fixed to the threaded rod 35. Then, the rotating rod 39 and the rotating block 310 are operated so that the rotating block 310 can fit with the foot. At this time, the locking rod 313 is pressed so that the locking rod 313 can be locked into the inner wall of the locking hole 314 for fixation.
[0055] refer to Figure 1 and Figure 7 The adjusting and fixing structure 4 also includes a U-shaped frame 41 fixedly connected to the top of the outer surface of the fixed base plate 1. A rotating round rod 42 is rotatably connected between the two sides of the inner wall of the U-shaped frame 41. A rotating cylinder 43 is fixedly connected to the outer surface of the rotating round rod 42. An elastic pull rope 2 is wrapped and fixed to the outer surface of the rotating cylinder 43. A round baffle 44 is fixedly connected to both sides of the outer surface of the rotating cylinder 43. The same U-shaped plate 45 is fixedly connected to one side of the outer surface of the two round baffles 44.
[0056] By setting a rotating rod 42 and a rotating cylinder 43, the elastic pull rope 2 can be wrapped around the outer surface of the rotating cylinder 43, thereby allowing the elastic pull rope 2 to be stored and assisted in being extended, and the elastic pull rope 2 can be extended to a suitable length for use.
[0057] refer to Figure 1 and Figure 7A circular rotating rod 46 is rotatably connected between the two sides of the inner wall of the U-shaped plate 45. A circular rotating cylinder 47 is fixedly connected to the outer surface of the circular rotating rod 46. An arc-shaped contact plate 48 is fixedly connected to the outer surface of the circular rotating cylinder 47. The arc-shaped contact plate 48 is composed of two arcs and the bend is arc-shaped. A first torsion spring 49 is sleeved on the outer surface of the circular rotating rod 46. The two ends of the first torsion spring 49 are fixedly connected to the outer surface of the circular rotating cylinder 47 and the outer surface of the U-shaped plate 45, respectively.
[0058] By setting up a circular rotating rod 46 and a circular rotating cylinder 47, the arc-shaped contact plate 48 can drive the circular rotating rod 46 and the circular rotating cylinder 47 to rotate, thereby allowing the arc-shaped contact plate 48 to fit against the side of the shoe. Due to its arc-shaped design, it will not cause marks on the shoe. Furthermore, under the action of the first torsion spring 49, the arc-shaped contact plate 48 can be reset when not in use.
[0059] refer to Figure 7 A rectangular connecting block 410 is fixedly connected to the top of the outer surface of two round baffles 44. A rectangular clamping frame 411 is fixedly connected to one side of the outer surface of the rectangular connecting block 410. A first wire hole 412 is opened on the inner wall of one side of the rectangular connecting block 410. A second wire hole 413 is opened on the inner wall of the rectangular clamping frame 411. The elastic pull rope 2 passes through the inner walls of the first wire hole 412 and the second wire hole 413. A threaded rod 414 is rotatably connected to the top of the outer surface of the rectangular connecting block 410. A screw hole plate 415 is threadedly connected to the outer surface of the threaded rod 414. A rectangular clamping block 418 is fixedly connected to the bottom of the outer surface of the screw hole plate 415.
[0060] By setting a rectangular clamping frame 411 and a rectangular clamping block 418, the rectangular clamping block 418 can cooperate with the rectangular clamping frame 411 to clamp, thereby assisting in fixing the elastic pull rope 2. The elastic pull rope 2 can pass through the inner wall of the first wire hole 412 and the second wire hole 413, and then perform auxiliary transmission clamping under the action of the threaded rod 414 and the screw hole plate 415.
[0061] refer to Figure 7 and Figure 8 A rectangular auxiliary block 416 is fixedly connected to both sides of the outer surface of the screw hole plate 415. A limit rod 417 is slidably provided on the inner wall of the rectangular auxiliary block 416. The bottom of the outer surface of the limit rod 417 is fixedly connected to the top of the outer surface of the rectangular connecting block 410. A first rectangular protrusion 419 is fixedly connected to the bottom of the outer surface of the rectangular clamping block 418. A second rectangular protrusion 420 is fixedly connected to the bottom of the inner wall of the rectangular clamping frame 411.
[0062] By setting the limiting rod 417, the screw hole plate 415 can be assisted in limiting the position. At the same time, under the action of the first rectangular protrusion 419 and the second rectangular protrusion 420, the elastic pull rope 2 can be assisted in fixing, so that the elastic pull rope 2 can be fixed and tightened.
[0063] With the above structure, the elastic cord 2 is moved around so that the rotating cylinder 43 remains stationary. At this time, the elastic cord 2 can slide on the inner wall of the first thread hole 412 and the second thread hole 413. When the elastic cord 2 is pulled out to an appropriate length, the threaded rod 414 is rotated so that the threaded plate 415 can drive the rectangular clamping block 418 to move, thereby allowing it to engage and fix with the rectangular clamping frame 411. Then, under the action of the first rectangular protrusion 419 and the second rectangular protrusion 420, the elastic cord 2 is further fixed. During use, when the elastic cord 2 is pulled, the rotating cylinder 43 and the rotating rod 42 can rotate slightly, so that the arc-shaped contact plate 48 can fit against the foot, thereby driving the circular rotating rod 46 and the circular rotating cylinder 47 to rotate, and then driving the first torsion spring 49 to rotate, thereby preventing the elastic cord 2 from causing marks and damage to the foot.
[0064] refer to Figure 9 and Figure 10 The anti-detachment pull ring structure 5 also includes a hook body 52 fixedly connected to one end of the elastic pull rope 2. An auxiliary pull block 51 is fixedly connected to the top of the outer surface of the hook body 52. The auxiliary pull block 51 is composed of a rectangular block at the bottom and an arc frame at the top. An auxiliary rectangular block 53 is fixedly connected to the end of the outer surface of the hook body 52 away from the auxiliary pull block 51. A rectangular auxiliary groove 54 is provided on one side of the outer surface of the auxiliary rectangular block 53. The rectangular auxiliary groove 54 passes through the bottom of the auxiliary rectangular block 53. An auxiliary rotating rod 55 is rotatably connected between the two sides of the inner wall of the rectangular auxiliary groove 54. An auxiliary rotating block 56 is fixedly connected to the outer surface of the auxiliary rotating rod 55. A stop bar 57 is fixedly connected to the outer surface of the auxiliary rotating block 56. A second torsion spring 58 is sleeved on the outer surface of the auxiliary rotating rod 55. The two ends of the second torsion spring 58 are fixedly connected to the inner wall of the rectangular auxiliary groove 54 and the outer surface of the auxiliary rotating block 56, respectively.
[0065] By setting the hook body 52, it can be fixed with the elastic pull rope 2. Then, under the action of the stop rod 57, since the stop rod 57 will not rotate upward, it can prevent the elastic pull rope 2 from causing the stop rod 57 to rotate from the inside and detach from the hook body 52. And under the action of the second torsion spring 58, the stop rod 57 can be reset.
[0066] refer to Figure 10An elastic cord 59 is fixedly connected to one side of the outer surface of the auxiliary pull block 51. A fixing strap 510 is fixedly connected to the end of the outer surface of the elastic cord 59 away from the auxiliary pull block 51. A rectangular ring frame 511 is fixedly connected to one end of the outer surface of the fixing strap 510. The end of the fixing strap 510 away from the rectangular ring frame 511 can pass through the inner wall of the rectangular ring frame 511. A hook-and-loop fastener 512 is fixedly connected to the top of the outer surface of the fixing strap 510 near the rectangular ring frame 511. A loop fastener 513 is fixedly connected to the bottom of the outer surface of the fixing strap 510 away from the rectangular ring frame 511. The hook-and-loop fastener 512 and the loop fastener 513 are glued and fixed together.
[0067] By setting a fixing strap 510, the auxiliary pull block 51 can be fixed to the wrist, and then the hook-and-loop fasteners 512 and loop fasteners 513 can be used for auxiliary fixation, so that when the auxiliary pull block 51 is released, it will not cause injury to other parts of the body.
[0068] With the above structure, when in use, one end of the elastic pull rope 2 is looped, and then the stop bar 57 is pressed, so that the stop bar 57 can drive the auxiliary rotating block 56 and the auxiliary rotating rod 55 to rotate, which in turn can drive the second torsion spring 58 to deform. At this time, the elastic pull rope 2 can be fixed to the hook body 52. At this time, under the action of the second torsion spring 58, the stop bar 57 can be reset. Then, the fixing strap 510 is fixed to the wrist, and one end of the fixing strap 510 is passed through the rectangular ring frame 511, so that the hook-face hook and loop hook 512 and the loop hook 513 are attached and fixed, and then the auxiliary pull block 51 is fixed to the hand.
[0069] The overall working principle described above is as follows:
[0070] When in use, tie one end of the elastic pull rope 2 into a loop, then press the stop bar 57 so that the stop bar 57 can drive the auxiliary rotating block 56 and the auxiliary rotating rod 55 to rotate, which in turn can drive the second torsion spring 58 to deform. At this time, the elastic pull rope 2 can be fixed to the hook body 52. At this time, under the action of the second torsion spring 58, the stop bar 57 can be reset.
[0071] At this point, the fixing strap 510 is fixed to the wrist, and then one end of the fixing strap 510 is passed through the rectangular ring 511, so that the hook-and-loop fastener 512 and the loop fastener 513 are attached and fixed, and then the auxiliary pull block 51 can be fixed to the hand.
[0072] Previously, the elastic cord 2 was rotated so that the rotating cylinder 43 remained stationary. At this time, the elastic cord 2 could slide on the inner wall of the first thread hole 412 and the second thread hole 413. When the elastic cord 2 was pulled out to an appropriate length, the threaded rod 414 was rotated so that the threaded plate 415 could drive the rectangular clamping block 418 to move, thereby enabling it to engage and fix with the rectangular clamping frame 411. Then, under the action of the first rectangular protrusion 419 and the second rectangular protrusion 420, the elastic cord 2 was further fixed.
[0073] When the elastic cord 2 is pulled, the rotating cylinder 43 and the rotating rod 42 can rotate slightly, so that the arc-shaped contact plate 48 can fit against the foot, thereby driving the circular rod 46 and the circular cylinder 47 to rotate, which in turn drives the first torsion spring 49 to rotate, thus preventing the elastic cord 2 from causing marks and damage to the foot.
[0074] The rectangular locking block 32 is inserted into the inner wall of the rectangular locking frame 31, and then the threaded rod 35 is inserted into the first insertion hole 33 and the second insertion hole 34. At this time, the fixing nut 36 is fixed to the threaded rod 35. Then, the rotating rod 39 and the rotating block 310 are operated so that the rotating block 310 can fit with the foot. Then, the locking rod 313 is pressed so that the locking rod 313 can be locked into the inner wall of the locking hole 314 for fixation.
[0075] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
