This application also claims priority to Chinese Patent Application No. 202521661404.5, filed on August 5, 2025, entitled "Tightener", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of cord and belt buckle technology, and in particular to a tensioner. Background Technology

[0003] A tensioner is a device used to wind up filamentous materials such as cables and ropes. It can tighten the filamentous material by winding it up or loosen it by unwinding it.

[0004] A rope tensioner, as described in CN 221459524 U, includes a fixed base assembly, a rope take-up reel, an elastic element, a rotating element, and a button. The rope take-up reel and the rotating element are rotatably connected to the fixed base assembly. The rotating element covers the rope take-up reel. The outer side wall of the fixed base assembly and the inner side wall of the rotating element form a ratchet connection. One end of the elastic element abuts against the center of the rope take-up reel, and the other end of the elastic element abuts against the bottom center of the button. The button passes through the center of the rotating element and forms a sliding connection with the rotating element along a track. Rotating the rotating element in the forward direction can drive the button to slide downward along the track, thus forming a transmission connection between the button and the rope take-up reel. If the rotating element continues to rotate, it can drive the rope take-up reel to rotate to wind up the rope. Pressing the button can cause the button to spring upward along the track to release the rope take-up reel. However, in this tensioner, when the rotating part rotates in the forward direction, it will cause the button to rotate as well. Therefore, the button cannot slide down steadily along the trajectory of the rotating part. In fact, the user needs to press the button while rotating the rotating part to make it slide down along the trajectory of the rotating part. This makes the operation of this type of tensioner more troublesome and less convenient in actual use. Summary of the Invention

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0063] This embodiment provides a tensioner, combined with Figure 1-2 It can be seen that the tensioner includes:

[0064] Install component 1;

[0065] The rope reel 2 is movably mounted on the mounting assembly 1. The rope reel 2 is capable of winding and unwinding the rope.

[0066] Rotating disk 3 is movably mounted on mounting assembly 1 and is capable of rotating on mounting assembly 1 in a first direction; and,

[0067] Button assembly 4 is movably mounted on rotating disk 3, and rotating disk 3 can drive button assembly 4;

[0068] When the rotating disk 3 rotates in the first direction, the button assembly 4 driven by the rotating disk 3 can move along the axial direction of the rotating disk 3 toward the winding disk 2 under the guidance of the mounting assembly 1, so as to drive the winding disk 2 to connect with the winding disk 2, so that the rotating disk 3 can drive the winding disk 2 to wind up the rope through the button assembly 4.

[0069] When the button assembly 4 is pressed, it can disengage from the winding reel 2 along the axial direction of the rotating disk 3, so that the winding reel 2 can unwind the rope.

[0070] When it is necessary to wind up the rope, turn the rotating disk 3 to rotate in the first direction. The rotating disk 3 can drive the button assembly 4 to rotate. At this time, the mounting assembly 1, which is stationary relative to the rotating disk 3, can guide the button assembly 4, so that the button assembly 4 moves towards the winding disk 2 to connect with the winding disk 2. In turn, the rotating disk 3 drives the winding disk 2 to rotate in the first direction through the button assembly 4 to wind up the rope. In this process, there is no need to manually press the button assembly 4. You only need to rotate the rotating disk, which makes the operation simpler and more convenient.

[0071] In some embodiments, a winding groove 21 is provided around the periphery of the winding reel 2. The winding groove 21 can wind up the rope when the winding reel 2 rotates in a first direction, or unwind the rope when the winding reel 2 rotates in a second direction.

[0072] When the take-up reel 2 rotates in the first direction, the rope can be wound into the take-up groove 21 so that the take-up reel 2 can take up the rope; when the take-up reel 2 rotates in the second direction, the rope can be released from the take-up groove 21 so that the take-up reel 2 can unwind the rope.

[0073] In some embodiments, the mounting assembly 1 includes a ratchet disk 11, which is ratcheted to the rotating disk 3 to restrict the rotating disk 3 from rotating in a second direction;

[0074] When the rotating disk 3 rotates in the first direction, the button assembly 4 driven by the rotating disk 3 can move along the axial direction of the rotating disk 3 toward the winding disk 2 under the guidance of the ratchet disk 11 so as to be connected to the winding disk 2 in a transmission manner.

[0075] The ratchet disc 11 is connected to the ratchet of the rotating disc 3 to restrict the rotation of the rotating disc 3 in the second direction, so that the rotating disc 3 can only rotate in the first direction, so as to control the winding disc 2 to wind up the rope.

[0076] In some embodiments, the rotating disk 3 is connected to the ratchet disk 11 on the outer periphery with ratchet teeth, a first guide body 111 is provided on the inner side of the ratchet disk 11, a first rotating body 41 is provided on the outer periphery of the button assembly 4, and the rotating disk 3 and the ratchet disk 11 are both sleeved on the outer side of the button assembly 4.

[0077] When the button assembly 4 rotates in the first direction, it can move along the axis of the rotating disk 3 toward the winding disk 2 through the guiding cooperation between the first guide body 111 and the first rotating body 41, so as to be connected to the winding disk 2 in a transmission manner.

[0078] With the cooperation of the first guide body 111 and the first rotating body 41, when the rotating disk 3 is turned, the button assembly 4 can move along the axis of the rotating disk 3 toward the winding disk 2 to be connected to the winding disk 2 for transmission. This process does not require manual pressing of the button assembly 4, making the operation more convenient.

[0079] In some embodiments, the first guide body 111 has a first guide slope 1111, and the first rotating body 41 has a second guide slope 411. When the button assembly 4 rotates along the first direction, it is guided by the first guide slope 1111 of the first guide body 111 against the second guide slope 411 of the first rotating body 41. The button assembly 4 can move along the axial direction of the rotating disk 3 toward the winding disk 2 so as to be connected to the winding disk 2 in a transmission manner.

[0080] When the rotating disk 3 is turned, the rotating disk 3 can drive the button assembly 4 to rotate, so that the first guide body 111 moves toward the first rotating body 41; and when the first guide slope 1111 abuts against the second guide slope 411, the button assembly 4 can move along the axis of the rotating disk 3 toward the winding disk 2 under the cooperation of the first guide slope 1111 and the second guide slope 411.

[0081] In some embodiments, there are multiple first guide bodies 111, which are arranged around the inner side of the ratchet disk 11, and multiple first rotating bodies 41, which are arranged around the outer periphery of the button assembly 4.

[0082] The cooperation of multiple first guide bodies 111 and multiple first rotating bodies 41 makes the process of the button assembly 4 moving along the axis of the rotating disk 3 toward the winding disk 2 more stable.

[0083] In some embodiments, the button assembly 4 is provided with a second rotating body 42, and the rotating disk 3 is provided with a guide block 31, with the second rotating body 42 corresponding to the guide block 31;

[0084] When the rotating disk 3 rotates, along the circumference of the rotating disk 3, the rotating disk 3 can cooperate with the second rotating body 42 through the guide block 31 to drive the button assembly 4 to rotate, and along the axial direction of the rotating disk 3, the guide block 31 can guide the movement of the button assembly 4 toward or away from the direction of the rope winding disk 2.

[0085] When the rotating disk 3 rotates, the button assembly 4 can be driven to rotate through the cooperation of the guide block 31 and the second rotating body 42. At the same time, the guide block 31 can also guide the movement of the button assembly 4 toward or away from the direction of the winding reel 2, so as to further improve the stability of the movement of the button assembly 4 toward or away from the direction of the winding reel 2.

[0086] In some embodiments, the guide block 31 has a locking position 311, which can restrict the movement of the second rotating body 42 away from the direction of the rope take-up reel 2;

[0087] When the rotating disk 3 drives the button assembly 4 to rotate in the first direction, the button assembly 4 can move along the axial direction of the rotating disk 3 towards the winding disk 2 under the guidance of the mounting assembly 1, so that the button assembly 4 is connected to the winding disk 2 in a transmission manner, and the second rotating body 42 enters the locking position 311.

[0088] When the button assembly 4 is pressed, the second rotating body 42 can disengage from the locking position 311 along the axial direction of the rotating disk 3, and the button assembly 4 can move away from the direction of the winding disk 2 to disengage from the winding disk 2.

[0089] When it is necessary to wind up the rope, the rotating disc 3 is controlled to rotate, thereby controlling the second rotating body 42 to enter the locking position 311, so that the button assembly 4 remains in transmission connection with the winding disc 2; when it is necessary to unwind the rope, the button assembly 4 is pressed, thereby controlling the second rotating body 42 to disengage from the locking position 311, so that the button assembly 4 is disengaged from the winding disc 2.

[0090] In some embodiments, the tensioner further includes a first elastic element 5, one end of which is connected to the button assembly 4, and the other end of which is connected to the cord reel 2.

[0091] When the button assembly 4 is pressed, along the axial direction of the rotating disk 3, the button assembly 4 can move toward the winding disk 2, and the second rotating body 42 can disengage from the locking position 311.

[0092] After the button assembly 4 is released, the button assembly 4, which is out of the locking position 311, can move along the axis of the rotating disk 3 away from the winding disk 2 under the action of the elastic restoring force of the first elastic element 5 so as to disengage from the winding disk 2.

[0093] When it is necessary to wind up the rope, the rotating disc 3 is controlled to rotate, thereby controlling the button assembly 4 to compress the first elastic element 5. At the same time, the second rotating body 42 enters the locking position 311 so that the button assembly 4 remains connected to the winding disc 2. When it is necessary to unwind the rope, the button assembly 4 is pressed first to further compress the first elastic element 5. At the same time, the second rotating body 42 disengages from the locking position 311. Then the button assembly 4 is released, and under the elastic restoring force of the first elastic element, the button assembly 4 disengages from the winding disc 2.

[0094] By placing the first elastic element 5 between the winding reel 2 and the button assembly 4, it can assist the button assembly 4 in resetting when it is pressed, and also support it between the winding reel 2 and the button assembly 4 when the rope is unwound, so that the two are not connected.

[0095] For example, the first elastic element 5 is a spring.

[0096] In some embodiments, combined with Figure 6It can be seen that the first elastic element 5 is a spring, the mounting assembly 1 includes a base 12 and a rotating shaft 13, one end of the rotating shaft 13 is fixed to the base 12, the rope take-up reel 2 is set on the base 12, the other end of the first elastic element 5 passes through the rope take-up reel 2, the rope take-up reel 2 can rotate in a first direction or in a second direction with the rotating part 131 as the rotation center, one end of the first elastic element 5 is connected to the button assembly 4, and the other end of the first elastic element 5 is sleeved on the other end of the rotating shaft 13 and connected to the rope take-up reel 2.

[0097] In some embodiments, the tensioner further includes a first elastic element 5, one end of which is connected to the button assembly 4, and the other end of which is connected to the mounting assembly 1.

[0098] When the button assembly 4 is pressed, along the axial direction of the rotating disk 3, the button assembly 4 can move toward the winding disk 2, and the second rotating body 42 can disengage from the locking position 311.

[0099] After the button assembly 4 is released, the button assembly 4, which is out of the locking position 311, can move along the axis of the rotating disk 3 away from the winding disk 2 under the action of the elastic restoring force of the first elastic element 5 so as to disengage from the winding disk 2.

[0100] When it is necessary to wind up the rope, the rotating disc 3 is controlled to rotate, thereby controlling the button assembly 4 to compress the first elastic element 5. At the same time, the second rotating body 42 enters the locking position 311 so that the button assembly 4 remains connected to the winding disc 2. When it is necessary to unwind the rope, the button assembly 4 is pressed first to further compress the first elastic element 5. At the same time, the second rotating body 42 disengages from the locking position 311. Then the button assembly 4 is released, and under the elastic restoring force of the first elastic element 5, the button assembly 4 disengages from the winding disc 2.

[0101] By placing the first elastic element 5 between the mounting component 1 and the button component 4, it can assist the button component 4 in resetting when it is pressed; and it can also support the winding reel 2 and the mounting component 1 when the rope is unwound, so that the two are not connected and will not interfere with the rotation of the winding reel 2.

[0102] In some embodiments, combined with Figure 3 and Figure 5 It can be seen that this embodiment is similar to... Figure 6 The difference in the illustrated embodiment lies in the installation position of the first elastic element 5. The mounting assembly 1 includes a base 12 and a rotating shaft 13. The rotating shaft 13 includes a rotating part 131 and a connecting part 132 connected together. The rotating part 131 is fixedly connected to the base 12. The winding reel 2 is disposed on the base 12 and sleeved on the rotating part 121. The winding reel 2 can rotate in a first direction or in a second direction with the rotating part 131 as the rotation center. The first elastic element 5 is sleeved on the connecting part 132 and abuts against the rotating part 131.

[0103] One end of the rotating shaft 13 is fixedly connected to the base 12 to make the positional relationship between the winding reel 2 and the base 12 more stable, so as to ensure the stability of the winding reel 2 when it rotates.

[0104] In some embodiments, combined with Figure 2 and Figure 4 It can be seen that this embodiment is similar to... Figure 3 and Figure 5 The difference in the embodiment shown lies in the connection relationship between the rotating shaft and the base. The mounting assembly 1 includes a base 12 and a rotating shaft 13. The rotating shaft 13 includes a rotating part 131 and a connecting part 132 connected together. The rotating part 131 is detachably connected to the base 12. The winding reel 2 is disposed on the base 12 and sleeved on the rotating part 121. The winding reel 2 can rotate in a first direction or in a second direction with the rotating part 131 as the rotation center. The first elastic member 5 is sleeved on the connecting part 132 and abuts against the rotating part 131.

[0105] One end of the rotating shaft 13 is detachably connected to the base 12. This split design makes it easier to assemble the rope winding disc 2 and the base 12.

[0106] For example, one end of the rotating shaft 13 is detachably connected to the base 12. This can be because the base 12 has a slot, and one end of the rotating shaft 13 extends into the slot; or the base 12 does not have a slot, and the button assembly 4 presses against the other end of the rotating shaft 13 through the first elastic member 5, so that one end of the rotating shaft 13 abuts against the base 12.

[0107] One end of the rotating shaft 13 is fixedly connected to the base 12 to make the positional relationship between the winding reel 2 and the base 12 more stable, so as to ensure the stability of the winding reel 2 when it rotates.

[0108] In some embodiments, the guide block 31 further has a first guide trajectory 312 and a second guide trajectory 313. The first guide trajectory 312 and the second guide trajectory 313 are respectively connected to both sides of the locking position 311. The second rotating body 42 can enter the locking position 311 along the first guide trajectory 312. The second rotating body 42 that is out of the locking position 311 can move along the second guide trajectory 313 so that the button assembly 4 is disengaged from the rope reel 2.

[0109] Based on the setting of the first guide trajectory 312 and the second guide trajectory 313, the second rotating body 42 of the button assembly 4 is more stable during movement.

[0110] In some embodiments, there are multiple guide blocks 31, which are arranged around the inner side of the rotating disk 3. Along the first direction, the second guide trajectory 313 of any guide block 31 can connect with the first guide trajectory 312 of the adjacent guide block 31, so that when the second rotating body 42 rotates to any position along the first direction, there is always a guide block 31 that can cooperate with the second rotating body 42, so that the cooperation between the rotating disk 3 and the button assembly 4 is more stable.

[0111] In some embodiments, the button assembly 4 is provided with a plurality of second rotating bodies 42 around its outer periphery, and the plurality of second rotating bodies 42 are respectively provided for a plurality of guide blocks 31. The provision of a plurality of second rotating bodies 42 further improves the stability of the button assembly 4 when rotating.

[0112] In some embodiments, combined with Figure 2 and Figure 7 It is understood that the tensioner also includes an unlocking disc 6, which is connected to the rotating disc 3. The unlocking disc 6 is provided with a second guide body 61. When the button assembly 4 is pressed, it moves along the axial direction of the rotating disc 3 towards the winding disc 2, causing the second rotating body 42 to disengage from the locking position 311 and be guided by the second guide body 61 to be offset from the locking position 311. Based on the second guide body 61, when the button assembly 4 is pressed, it can be ensured that the second rotating body 42 is offset from the locking position 311.

[0113] In some embodiments, the second guide body 61 has a third guide slope 611, and the second rotating body 42 has a fourth guide slope 421. When the button assembly 4 is pressed, along the axial direction of the rotating disk 3, the button assembly 4 moves toward the winding disk 2, so that the second rotating body 42 disengages from the locking position 311, and the fourth guide slope 421 of the second rotating body 42 abuts against the third guide slope 611 of the second guide body 61, so that the second rotating body 42 is misaligned from the locking position 311.

[0114] When the button assembly 4 is pressed, the second rotating body 42 moves toward the second guide body 61. At this time, the fourth guide slope 421 and the third guide slope 611 abut against each other, so that the second rotating body 42 is displaced from the locking position 311 under the cooperation of the two.

[0115] In some embodiments, combined with Figure 3 and Figure 8 It can be seen that this embodiment is similar to... Figure 2 and Figure 7The difference in the illustrated embodiment is the button assembly 4, which includes a first button 43, a second button 44, and a second elastic member 45. The first button 43, the second button 44, and the second elastic member 45 are all disposed on the rotating disk 3. The first button 43 and the second button 44 are arranged along the axial direction of the rotating disk 3. The two ends of the second elastic member 45 are respectively connected to the first button 43 and the second button 44, and the second rotating body 42 is located on the side of the first button 43 away from the rotating disk 3.

[0116] When the rotating disk 3 drives the second button 44 to rotate in the first direction, the second button 44 can move toward the winding disk 2 under the guidance of the mounting component 1 to be connected to the winding disk 2 in a transmission, so that the rotating disk 3 can drive the winding disk 2 to rotate in the first direction through the second button 44.

[0117] When the first button 43 is pressed, the second button 44 continues to move toward the winding reel 2 under the force of the first button 43 and can disengage from the locking position 311; when the first button 43 is released, the second button 44 can disengage from the winding reel 2 so that the winding reel 2 can rotate in the second direction.

[0118] Based on the connection between the first button 43 and the second button 44 via the second elastic element 45, the second button 44 moves toward the winding reel 2 to be connected to the winding reel 2 in a transmission manner. With the support of the second elastic element 45, the first button 43 can still protrude outside the rotating disk 3, so as to facilitate pressing the first button 43.

[0119] In some embodiments, the rotating disk 3 is provided with a sliding groove 32, and the first button 43 is provided with a slider 431. The slider 431 is movably disposed in the sliding groove 32, which can guide the movement of the first button 43 toward or away from the second button 44, so that the movement of the first button 43 toward or away from the second button 44 is more stable.

[0120] In some embodiments, the first button 43 is provided with a pressing part 432. When the first button 43 is pressed, the pressing part 432 can push the second button 44 to move toward the winding reel 2 and cause the second rotating body 42 to enter the second guide trajectory 313, so as to ensure that the second button 44 can disengage from the winding reel 2 and reset.

[0121] In some embodiments, the second rotating body 42 is provided with a fifth guide slope 422. When the first button 43 is pressed, the pressing part 432 can abut against the fifth guide slope 422 to push the second button 44 to move toward the rope winding disc 2 and cause the second rotating body 42 to enter the second guide trajectory 313.

[0122] When the pressing part 432 can contact the fifth guide slope 422, it pushes the second button 44 to move toward the rope reel 2, and because of the setting of the fifth guide slope 422, the second rotating body 42 is deflected to enter the second guide trajectory 313.

[0123] In the application, there are two connection relationships between the rotating shaft 13 and the base 12, two installation methods for the first elastic element 5, and two structural designs for the button assembly 4; among them, any one connection relationship between the rotating shaft 13 and the base 12, any one installation method for the first elastic element 5, and any one structural design for the button assembly 4 can be combined.
