However, the rope wound around the knob structure generally cannot be hidden, and the rope always exposed to the environment will affect the overall aesthetics of the sports protective gear. Moreover, for the current knob structure, the stability after adjustment is not good enough, and the rope may become loose during use, thus affecting the use effect of the structure. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems that the knob structure in the prior art is not beautiful and the rope is prone to looseness, and a rope tightening device is proposed.

[0027] Embodiment:

[0028] Refer to Figures 1-6, A cord tightening device, including a connecting plate 1, further comprising: a connecting disk 6 fixedly connected to the connecting plate 1. Among them, the connecting disk 6 fits the surface of the connecting plate 1 to form an open cavity. A turntable 8 is rotatably connected to the connecting disk 6. The outer wall of the turntable 8 fits the open end of the connecting disk 6. And the connecting disk 6 is provided with a rope outlet hole 7, and the rope outlet hole 7 is communicated with the open cavity; a gear 12 fixedly connected to the turntable 8. Among them, a tightening and loosening clamping mechanism is arranged on the connecting disk 6. When the clamping end of the tightening and loosening clamping mechanism abuts against or separates from the outer wall of the gear 12, the turntable 8 is locked or unlocked. A connecting column 9 is fixedly connected to the turntable 8. The connecting column 9 extends into the open cavity and is provided with a rope locking hole 10. And a limiting disk is also arranged on the connecting column 9, which can limit the wound rope to prevent the rope from running off.

[0029] Both the rope locking hole 10 and the rope outlet hole 7 are symmetrically arranged in two groups and are both arranged in the open cavity of the connecting disk 6.

[0030] When the device needs to be used, the connecting plate 1 can be installed on the protective gear. The installation operation is as follows: Connect one end of the connecting rope to the first group of rope locking holes 10 and fix the rope. Then pass the rope through the first group of rope outlet holes 7 so that the rope extends to the outside of the open cavity. Then cross-wind the rope around the connecting joint of the protective gear to be replaced. Subsequently, pass the rope through the second group of rope outlet holes 7 again and enter the connecting disk 6. Then lock and tie the connecting end of the rope to the second group of rope locking holes 10 to form a closed loop.

[0031] The tightness of the rope can be changed by the tightening and loosening clamping mechanism. When the rope needs to be adjusted, the clamping end of the tightening and loosening clamping mechanism can be separated from the outer wall of the gear 12. At this time, the turntable 8 can be continuously rotated clockwise or counterclockwise, so that the connecting column 9 rotates in the open cavity, thereby winding the rope on the rope locking hole 10, making the rope always in the open cavity and hiding the wound rope. And the limiting disk on the connecting column 9 can limit the wound rope to prevent the rope from running off. At this time, the rope is locked. When the length and tightness of the rope are appropriate, then make the clamping end of the tightening and loosening clamping mechanism abut against the outer wall of the gear 12 on the turntable 8. At this time, the clamping end will lock the gear 12 on the turntable 8 to form a fixation.

[0032] By rotating the turntable 8, the tightness of the rope can be adjusted, and the rope can be shielded and hidden by using the open cavity formed by the connecting disk 6 fitting the surface of the connecting plate 1. Thus, the aesthetics of the device on the sports protective gear can be improved, and the time for tying the rope can also be reduced, making it easier for the operator to master the tightness of the rope.

[0033] Furthermore, the above-mentioned loosening and clamping mechanism includes a first interface 2 and a second interface 3 respectively fixedly connected to the connecting plate 1. A first clamping plate 4 is rotatably connected to the first interface 2, and a second clamping plate 5 is rotatably connected to the second interface 3. A limiting hook is provided at the end of the clamping plate for locking the gear 12.

[0034] When it is necessary to unlock the gear 12, the first clamping plate 4 and the second clamping plate 5 can be rotated respectively to disengage the limiting hooks on the clamping plates from the outside of the gear 12. When it is necessary to lock the gear 12, the first clamping plate 4 and the second clamping plate 5 can be rotated and reset respectively to make the limiting hooks on the clamping plates abut against the grooves of the gear 12 to form a fixation.

[0035] In addition, in order to improve the stability between the gear 12 and the clamping plate during clamping, the cross-sectional shape of the gear 12 is trapezoidal, and as shown in Figure 2 and Figure 4 , the groove shape between the gears 12 is in the style of being larger outside and smaller inside, and the shape of the gear 12 is in the style of being smaller outside and larger inside. Through this kind of shape, the clamping effect of the first clamping plate 4 and the second clamping plate 5 can be improved.

[0036] An installation column 16 is fixedly connected inside the open cavity of the connection disk 6. A through hole 17 is provided on the connection column 9. The connection column 9 is rotatably connected to the installation column 16, and the through hole 17 is in fit with the outer wall of the installation column 16.

[0037] A hollow sleeve 11 is fixedly connected to the button disk 14. The hollow sleeve 11 abuts against the surface of the turntable 8, and the hollow sleeve 11 is communicated with the through hole 17. An installation hole 13 is provided on the outer wall of the gear 12, and the button disk 14 is detachably connected to the installation hole 13 through a limiting post 15.

[0038] The connection disk 6 can be connected to the connecting bolt through the installation column 16 and the through hole 17, and then extended into the hollow sleeve 11 to connect the connecting plate 1, the turntable 8 and the button disk 14 together.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
