[0029] Reference Figures 1 to 4 , an embodiment of the present application provides a rotary buckle type cord adjusting device, including a housing 10, a rotary cover 20 and a button 30. The housing 10 has a housing cavity 10 and a bottom cover 11 forming the bottom wall of the housing cavity 101. At the same time, a first engaging portion 12 is provided in the housing cavity 101 of the housing 10. Preferably, the first engaging portion 12 is located at the central position of the housing cavity 101. The outer circumference of the first engaging portion 12 is provided with first ratchet teeth. In addition, the housing 10 is further provided with a cord access hole 102 communicating with the housing cavity 101 for threading a cord. One end of the cord is fixed on the rotary cover 20. In this way, the cord can be wound or released by rotating the rotary cover 20;

[0030] The rotary cover 20 is elastically connected to the top of the housing 10, and the rotary cover 20 is provided with a second engaging portion 21. The second engaging portion 21 extends into the housing cavity 101 and is provided with second ratchet teeth 211 meshing with the first ratchet teeth. This meshing relationship enables the cord to be wound when the rotary cover 20 is rotated forward;

[0031] The buttons 30 are symmetrically arranged on both sides of the housing 10 with the first engaging portion 12 as the axis of symmetry. The buttons 30 are provided with a bevel structure 31 that can penetrate into the housing cavity 101. At the same time, the bevel structure 31 abuts against the bottom of the second engaging portion 21, and the thickness of the bevel structure 31 near the housing 10 is less than the thickness of the bevel structure 31 far from the housing 10. When the two buttons 30 are symmetrically pressed, the elastic potential energy between the rotary cover 20 and the housing 10 can be overcome to make the rotary cover 20 away from the housing 10, and then the second ratchet teeth 211 are disengaged from the first ratchet teeth, so that the cord can be released by rotating the rotary cover 20 in the reverse direction at this time. In this way, when winding the cord, the rotary cover 20 can be directly rotated forward, and when releasing the cord, only the buttons 30 need to be pressed simultaneously with the thumb and index finger, and then the rotary cover 20 is rotated in the reverse direction. Compared with the conventional method of using external force to pull out the rotary cover 20 or using external force to press the rotary cover 20 to release and wind the cord, it is more convenient to use and can reduce the operation intensity to a certain extent.

[0032] It should be noted that the forward rotation of the rotary cover 20 to wind up the cord and the reverse rotation of the rotary cover 20 to release the cord are merely examples. When the rotation direction of the first ratchet changes, it may also be that the cord is released by rotating the rotary cover 20 forward.

[0033] In one embodiment, the rotary cover 20 and the housing 10 are connected by a double-headed pin 40. The opposite ends of the double-headed pin 40 vertically penetrate through the bottom cover 11 and the rotary cover 20 respectively. At the same time, the top end 41 and the bottom end 42 of the double-headed pin 40 protrude from the rotary cover 20 and the bottom cover 11 respectively in the radial direction of the double-headed pin 40, where the radial direction refers to the direction perpendicular to the axial direction of the double-headed pin 40. In addition, a return spring 43 is sleeved on the double-headed pin 40 between the top end 41 and the rotary cover 20. When the button 30 is in the natural state, that is, when the button 30 is not pressed by an external force, the return spring 43 pulls the rotary cover 20 tightly, so that the second ratchet 211 and the first ratchet remain engaged. At this time, rotating the rotary cover 20 forward (under the meshing relationship of the first ratchet and the second ratchet 211, it can only rotate forward), the cord can be wound up. When the button 30 is pressed to overcome the elastic potential energy of the return spring 40, the rotary cover 20 moves away from the housing 10, and then the second ratchet 211 gradually disengages from the first ratchet. At this time, the rotary cover 20 can be rotated in the reverse direction to release the cord, which is convenient to operate and saves time and effort.

[0034] Further preferably, a guide sleeve 22 is provided at the top of the rotary cover 20. At the same time, the guide sleeve 22 and the top end 41 of the double-headed pin 40 are in clearance fit, and the return spring 43 is located inside the guide sleeve 22. On the one hand, the cooperation between the guide sleeve 22 and the double-headed pin 40 can form a guiding limit for the movement of the rotary cover 20, so as to ensure that the rotary cover 20 can only move longitudinally, making the working performance of the cord adjusting device more stable.

[0035] Further preferably, the snap-type cord adjusting device further includes a sealing cover 50. The sealing cover 50 is provided on the top of the rotary cover 20. At the same time, the outer peripheral part 51 of the sealing cover 50 is fixedly connected to the outer circumference of the rotary cover 20. In this way, the guide sleeve 22 can be completely covered by the sealing cover 50, so as to protect the guide sleeve 22 and prevent impurities, dust, etc. from entering and affecting the performance of the return spring 43 and the movement of the rotary cover 20.

[0036] Further preferably, anti-slip patterns 52 are provided on the outer surface of the outer peripheral part 51 of the sealing cover 50, which can facilitate the user to rotate the rotary cover 20 and prevent slipping.

[0037] In one embodiment, the rotating cover 20 is provided with a plurality of avoidance notches 201 at intervals on the outer circumference, and two first clamping protrusions 23 are symmetrically provided on the outer circumference, and at the same time, the sealing cover 50 is provided with a limiting clamping ring 53 and a limiting step 54 on the inner wall of the outer circumference, wherein the limiting clamping ring 53 cooperates with the avoidance notches 201 so as to be able to be inserted into two adjacent avoidance notches 201, thereby limiting the rotating cover 20 in the rotation direction of the rotating cover 20, and the rotating cover 20 can be rotated synchronously by rotating the sealing cover 50; wherein the first clamping protrusion 23 cooperates with the limiting step 54, so that the sealing cover 50 can be fixed to the top of the rotating cover 20 in a hooking manner through the first clamping protrusion 23, and the rotating cover 20 can be limited in the longitudinal direction, so that the sealing cover 50 and the rotating cover 20 are fitted together, thereby further ensuring the protective effect of the guide sleeve 22, and making the structural stability of the rope adjustment device better and more convenient to use.

[0038] In one embodiment, a second latching protrusion 32 is provided at one end of the inclined structure 31 close to the shell 10, and when the button 30 is not pressed, the second latching protrusion 32 abuts against the inner wall of the shell cavity 101, so that the button 30 can be limited on the shell 10. Even when the button 30 is not pressed, the button 30 will not be separated from the shell 10, thereby facilitating directly pressing the button 30 to release the rope.

[0039] Further preferably, the second latching protrusions 32 are symmetrically distributed in the axial direction of the shell 10. The symmetrically distributed second latching protrusions 32 can ensure the stability of the button 30 connected to the shell 10. At the same time, when the button 30 is not pressed, the button 30 still maintains a stable posture relative to the shell 10, which makes it convenient to directly press the button 30 so that the inclined surface structure 31 can drive the rotating cover 20 away from the shell 10, wherein the axial direction of the shell 10 is the extension direction of the first meshing portion 12, or the axial direction of the stud screw 40.

[0040] It should be noted that the terms "first, second" in the present application are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0041] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
