Description

Technical Field

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

[0002] Knob buckles are usually used in places where the tightness needs to be adjusted, such as shoelaces, VR glasses, physiotherapy eye masks, etc. The knob buckles currently on the market can generally only rotate in one direction. When the rope needs to be loosened, the rotary buckle needs to be pulled outward or other operations need to be performed to disengage the internal ratchet teeth and allow the internal winding wheel to rotate freely. Only then can the rope become loose, which increases the complexity of use and greatly reduces the user experience. In addition, the structure is relatively complex and is prone to malfunction after long-term use. Utility Model Content

DETAILED DESCRIPTION

[0021] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0023] The following will be combined with specific embodiments to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0024] See Figures 1 to 6 As shown, the structure of the utility model is: a knob buckle, including a base 2, a rotary cover 6 is rotatably provided on the base 2, a damping member is provided on the base 2 for providing a damping effect to the rotary cover 6, a first buckle 601 is provided on the rotary cover 6, and a first clamping groove 201 is provided on the base 2 to rotate with the first buckle 601 and clamped with each other, a wire groove 602 is provided on the first buckle 601, a wire rope 3 is passed through the wire groove 602, and the wire rope 3 extends outward through the base 2. Specifically, the rotary cover 6 is rotatably connected to the base 2 through the first buckle 601 to realize the rotatable function of the rotary cover 6. Rotating the rotary cover 6 drives the first buckle 601 to rotate, so that the wire rope 3 is wrapped around the first buckle 601, realizing the retraction and release of the wire rope 3, and at the same time, a certain resistance is provided to the rotary cover 6 through the damping member to ensure that the wire rope 3 will not loosen.

[0025] like Figure 3 、 Figure 4 As shown, the damping member includes a spring 4 arranged on the base 2, a steel ball 5 is provided at one end of the spring 4, and a groove 603 is provided on the inner side of the rotary cover 6 to abut against the steel ball 5. Specifically, the steel ball 5 is tightly clamped in the groove 603 of the rotary cover 6 under the action of the spring 4, providing sufficient damping to prevent the rotary cover from rotating; when the rotary cover 6 is rotated, the spring 4 contracts, the steel ball 5 exits the slot, and the rope 3 is wrapped around the first buckle 601 to realize the retraction and release of the rope 3.

[0026] like Figure 4As shown, the grooves 603 are evenly distributed in an annular shape on the inner side of the rotary cover 6, and a protrusion 604 with an arc-shaped structure is provided between two adjacent grooves 603. Specifically, when the rotary cover 6 is rotated, the steel ball 5 forces the spring 4 to be compressed through the arc-shaped protrusion 604, so that the steel ball 5 smoothly passes over the protrusion 604 and enters the next groove 603, thereby making the rotary cover 6 rotate more smoothly and reducing the noise when the rotary cover 6 rotates.

[0027] like Figure 4 As shown, the circumferential surface of the rotary cover 6 is provided with an anti-skid groove 605 . Specifically, the anti-skid groove 605 is used to prevent the rotary cover 6 from slipping when rotating.

[0028] like Figure 1 、 Figure 2 As shown, it also includes a fixing base 1, which is snap-connected with the base 2. Specifically, the fixing base 1 is used to install the base 2.

[0029] like Figure 2 、 Figure 5 、 Figure 6 As shown, a second slot 202 is provided at the bottom of the base 2, and a second buckle 101 is provided on the fixing base 1 to be engaged with the second slot 202. Specifically, the base 2 and the fixing base 1 are engaged with each other through the second buckle 101, which facilitates the installation and disassembly of the base 2.

[0030] like Figure 6 As shown, a positioning column 102 is provided on the fixing seat 1, and a positioning hole 203 corresponding to the positioning column 102 is provided on the base 2. Specifically, the positioning column 102 cooperates with the positioning hole 203 to ensure that the base 2 is installed in the correct direction.

[0031] like Figure 6 As shown, a pin shaft 103 rotatably connected to the first buckle 601 is provided in the middle of the fixing seat 1. Specifically, when the base 2 is installed to the fixing seat 1, the pin shaft 103 is inserted into the first buckle 601 to prevent the first buckle 601 from falling off due to elastic deformation when the rope 3 is wrapped around the first buckle 601.

[0032] During specific use, the rotary cover 6 is rotatably connected to the base 2 through the first buckle 601 to realize the rotatable function of the rotary cover 6. Rotating the rotary cover 6 drives the first buckle 601 to rotate, so that the rope 3 is wrapped around the first buckle 601 to realize the retraction and release of the rope 3. At the same time, the damping member provides a certain resistance to the rotary cover 6 to ensure that the rope 3 will not loosen.

[0033] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
