Description

A rope tensioner Technical Field

[0001] The utility model relates to the technical field of rope buckles, in particular to a rope loosener. Background Art

[0002] Cord buckles are mainly used to tighten or loosen cords in shoes, clothing, backpacks, and rehabilitation equipment. Cord buckles are being widely used. This type of product provides a portable experience for the majority of users, but there are still some problems with the existing manual tensioning buttons when using them.

[0003] Patent number CN108791997A is a rope device, which, when the rotor rotates in the forward direction, the rope will be wound onto the winding groove in the tightening direction. In this gear state, the rotor cannot be reversed, thereby realizing the function of tightening the rope. When the upper cover is pulled up, the pawl is disengaged from the teeth, and the rotor is no longer subject to unidirectional constraints. At the same time, the rotor upper cover is disconnected from the winding groove. At this time, the upper cover and the winding groove can rotate freely in both directions, thereby realizing automatic loosening of the rope; however, since the upper cover is on the outside, it will be easily pulled up under the action of external friction, causing the wound rope to become loose for no reason, and the tightening stability is not high, which is not conducive to user use. Moreover, the process of tightening the rope goes through two steps of pressing and turning the knob in sequence, and the overall tightening process is not convenient enough.

[0004] Therefore, it is necessary to propose a rope tensioner to improve the stability of rope tightening and simplify the rope tightening steps. Utility Model Content

[0005] In order to solve the above problems, the present invention proposes a rope tensioner to improve the stability of rope tightening and simplify the rope tightening steps.

[0006] The utility model is achieved through the following technical solutions:

[0007] The utility model proposes a rope tensioner, comprising a fixed seat assembly, a rope receiving disc, an elastic member, a rotating member, and a button. The rope receiving disc and the rotating member are rotatably connected to the fixed seat assembly, the rotating member covers the rope receiving disc, and the outer wall of the fixed seat assembly forms a ratchet connection with the inner wall of the rotating member. One end of the elastic member abuts the center of the rope receiving disc, and the other end of the elastic member abuts the bottom center of the button. The button passes through the center of the rotating member and forms a sliding connection with the rotating member with a track. Forward rotation of the rotating member can drive the button to slide downward along the track and form a transmission connection between the button and the rope receiving disc. Continuing rotation of the rotating member can drive the rope receiving disc to rotate to reel in the rope. Pressing the button can cause the button to bounce upward along the track to release the rope receiving disc.

[0008] Furthermore, the rotating member is provided with a through hole, the button passes through the through hole, a guide track is provided on the hole wall of the through hole, and both sides of the button extend into the guide track and are slidably connected to the guide track.

[0009] Furthermore, the guide track includes two sections of guide paths, which are connected to each other end to end. Guide columns are provided on both sides of the button, and the two guide columns correspond one-to-one to the two sections of the guide paths respectively. The guide columns extend into the guide paths and are slidably connected to the side walls of the guide paths.

[0010] Furthermore, the guide path includes an inclined slide, a clamping groove, and a reset path. The inclined slide, the clamping groove, and the reset path are connected in sequence, and the rear end of the inclined slide is connected to the front end of the reset path of the next section of the guide path.

[0011] Furthermore, the restoration path is vertical.

[0012] Furthermore, the snap-fitting groove is a semicircular groove.

[0027] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0028] Please refer to Figures 1 to 3. The present invention proposes a rope tensioner, including a fixed seat assembly 1, a rope drum 2, an elastic member 3, a rotating member 4, and a button 5. The rope drum 2 is used to roll the rope to tighten the rope. The rope drum 2 and the rotating member 4 are both rotatably connected to the fixed seat assembly 1. The rotating member 4 blocks the rope drum 2. The outer wall of the fixed seat assembly 1 and the inner wall of the rotating member 4 form a ratchet connection, so that the rotating member 4 can only rotate in the forward direction, and the forward rotation direction is clockwise. The elastic member 3 is a coil spring for pressing the button 5 provides an elastic force that can reset, one end of the elastic member 3 abuts against the center of the rope-taking drum 2, and the other end of the elastic member 3 abuts against the bottom center of the button 5. The button 5 passes through the center of the rotating member 4 and forms a sliding connection with the rotating member 4 having a track. The forward rotation of the rotating member 4 can drive the button 5 to slide downward along the track and form a transmission connection between the button 5 and the rope-taking drum 2. The continued rotation of the rotating member 4 can drive the rope-taking drum 2 to rotate to reel in the rope. Pressing the button 5 can make the button 5 bounce upward along the track to release the rope-taking drum 2.

[0029] In this embodiment, when tightening the rope, it is necessary to rotate the rotating member 4 in the forward direction, and the rotating member 4 can drive the button 5 to slide downward along the trajectory, and make the button 5 and the rope-taking drum 2 form a transmission connection. At this time, the button 5 is fixed to the rotating member 4 and the rope-taking drum 2 respectively, that is, the rotating member 4 continues to rotate and can drive the rope-taking drum 2 to rotate to reel in the rope, that is, there is no need to press the button 5 or the rotating member 4 when reeling in the rope, as long as the rotating member 4 is directly rotated in the forward direction. When the rotating member 4 is rotated in the forward direction, the button 5 will automatically drop. The button 5 is set at the center of the rotating part 4 and needs to be pressed to release the rope.

[0030] In summary, the rope tensioner can effectively improve the stability of rope tightening, while simplifying the rope tightening steps, which is convenient for users to use.

[0031] In this embodiment, the rotating member 4 is provided with a through hole 41, and the button 5 passes through the through hole 41. A guide track 42 is provided on the hole wall of the through hole 41. Both sides of the button 5 extend into the guide track 42 and are slidably connected with the guide track 42; when the rotating member 4 rotates forward, the guide track 42 moves circumferentially relative to the button 5, and at this time the button 5 is driven to descend by the guide track 42.

[0032] In this embodiment, the guide track 42 includes two sections of guide paths 421, which are connected end to end. The guide paths 421 are of a slide-type structure. Guide posts 51 are provided on both sides of the button 5. The guide posts 51 are cylindrical. The cylindrical guide posts 51 can be well adapted to the slide-type structure. The two guide posts 51 correspond to the two sections of guide paths 421 one by one. The guide posts 51 extend into the guide paths 421 and are slidably connected to the side walls of the guide paths 421. When the rotating member 4 rotates forward, the two sections of the guide paths 421 simultaneously move circumferentially relative to the two guide posts 51. At this time, the side walls of the guide posts 51 slide on the side walls of the guide paths 421, thereby The guide button 5 is lowered relative to the rotating member 4; the guide path 421 includes an inclined slide 4211, a clamping groove 4212, and a reset path 4213. The clamping groove 4212 is a semicircular groove, and the reset path 4213 is vertical. The inclined slide 4211, the clamping groove 4212, and the reset path 4213 are connected in sequence, and the rear end of the inclined slide 4211 is connected with the front end of the reset path 4213 of the next guide path 421. Before the rotating member 4 rotates forward, the upward elastic force of the elastic member 3 acts on the button 5, so that the button 5 has an upward abutting force, that is, the guide column 51 has an upward abutting force on the guide path 421. At this time, the guide column 51 is accommodated at the top of the reset path 4213. The button 5 is also in the highest position. When the rotating member 4 rotates forward, the guide post 51 slides out of the reset path 4213 and slides obliquely downward along the inclined slide 4211. At this time, the button 5 gradually drops. When the guide post 51 slides into the engaging groove 4212, the guide post 51 engages with the engaging groove 4212, so that the guide post 51 stays in the engaging groove 4212. The side wall of the guide post 51 fits with the top wall of the engaging groove 4212. At this time, the elastic member 3 is compressed, and the button 5 is fixed relative to the rotating member 4, that is, the button 5 is now integrated with the rotating member 4. At the same time, the bottom of the button 5 also forms a transmission connection with the winding disk 2. When the rotating member 4 rotates forward, the button 5 also follows They rotate forward together, that is, the rotation of the button 5 drives the winding disc 2 to rotate, so as to reel the rope and tighten the rope; when the button 5 is pressed, the side wall of the guide column 51 is disengaged from the top wall of the clamping groove 4212, and then under the guidance of the inclined bottom wall of the inclined slide 4211, the guide column 51 tilts toward the reset path 4213 and slides. At this time, the guide column 51 stays at the bottom end of the reset path 4213, and the elastic member 3 is compressed again. When the button 5 is released, the elastic member 3 is released, pushing the button 5 upward. At this time, the guide column 51 slides upward along the reset path 4213, so that the button 5 is reset. At this time, the winding disc 2 is released and the rope is released.

[0033] In this embodiment, a first ratchet 52 is provided at the bottom of the button 5, and a second ratchet 21 is provided on the upper surface of the rope collecting drum 2. The first ratchet 52 and the second ratchet 21 form a ratchet connection. When the button 5 is fixed relative to the rotating member 4, the rotating member 4 rotates forward and the button 5 also rotates forward. The button 5 drives the rope collecting drum 2 to rotate through the ratchet connection between the first ratchet 52 and the second ratchet 21. Since the button 5 is driven to descend by the rotation of the rotating member 4, the provision of the first ratchet 52 and the second ratchet 21 is conducive to the button 5 and the rope collecting drum 2 forming a transmission connection.

[0034] In this embodiment, a third ratchet 11 is provided on the outer peripheral side of the fixed seat assembly 1, and a fourth ratchet 43 is provided on the inner side wall of the rotating part 4. The third ratchet 11 and the fourth ratchet 43 form a ratchet connection. The arrangement of the third ratchet 11 and the fourth ratchet 43 enables the rotating part 4 to only rotate in the forward direction, that is, when tightening the rope, it can only rotate in the forward direction for tightening, and no reversal will be formed after tightening, which is convenient for users to use.

[0035] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
