Technical Field

[0001] The utility model relates to the technical field of elastic cord buckles, in particular to a double-hole anti-detachment elastic cord adjusting buckle. Background Art

[0002] An elastic cord is a slender strip material, usually made of materials with certain elasticity and flexibility such as rubber, spandex, polyester, polyester fiber, etc. The main function of the elastic cord is to be attached or added to other products to enable the products to achieve specific functions such as fixation, wearing, and convenient use, such as in the fields of masks, sunscreen protection masks, eye masks, hats, arm sleeves, clothing, etc.

[0003] In daily life, many products such as masks, sunscreen protection masks, eye masks, hats, arm sleeves, clothing, etc. are equipped with elastic cords. However, the length of traditional elastic cords is often fixed and cannot be flexibly adjusted according to the head sizes and wearing needs of different users, resulting in uncomfortable wearing or inconvenient use. Therefore, in view of the above problems, we propose a new double-hole anti-detachment elastic cord adjusting buckle. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem in the prior art that the length of the traditional elastic cord is often fixed and cannot be flexibly adjusted according to the head sizes and wearing needs of different users, resulting in uncomfortable wearing or inconvenient use, and to propose a double-hole anti-detachment elastic cord adjusting buckle.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: a double-hole anti-detachment elastic cord adjusting buckle, including a buckle shell, a partition plate is connected between the front and rear inner surfaces of the buckle shell, two sets of biting mechanisms are symmetrically arranged at positions on both sides of the partition plate inside the buckle shell, the biting mechanism includes a rotating shaft, pins are inserted at both the front and rear ends of the rotating shaft, a biting plate is rotatably sleeved on the outer surface of the rotating shaft, a pinch plate is fixedly connected to the top of the biting plate, and a second hook is fixedly connected to one side outer surface of the pinch plate.

[0006] Preferably, first hooks are symmetrically and fixedly connected to positions on the inner surfaces of both sides of the buckle shell near the lower part, and a tension cord is hooked between the first hook and the second hook.

[0007] Preferably, the pin is inserted on the outer surface of the buckle shell, and the end of the pin penetrates through the outer surface of the buckle shell and extends to the inside.

[0008] Preferably, the biting plate is inclined and the bottoms of the two biting plates are close to each other, the pinch plate is inclined and the pinch plate and the biting plate are parallel.

[0009] Preferably, the tension cord is in a contracted state.

[0010] Preferably, anti-slip rubber pads are adhesively connected to the outer surfaces of the opposite sides of the two nip plates near the top, and anti-slip patterns are provided on the outer surfaces of the anti-slip rubber pads.

[0011] Preferably, the bottom of the occlusal plate is provided with arc-shaped occlusal teeth.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0013] 1. In the present utility model, during use, after squeezing the nip plates, the occlusal plate can be driven to rotate around the rotation axis, so that it moves away from the partition plate and loses the extrusion and clamping of the elastic cord. Subsequently, the position of the buckle housing on the elastic cord can be adjusted arbitrarily. After releasing the nip plates, the nip plates and the occlusal plate can be driven to reset under the cooperation of the first hook, the second hook and the tension bar, so as to squeeze and fix the elastic cord again. The overall structure is small and convenient to use, and the tightness of the elastic cord can be adjusted according to needs, ensuring the comfort and firmness after the elastic cord is fixed.

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1: As Figures 1-4 shown, the present utility model provides a double-hole anti-detachment elastic cord adjusting buckle, which includes a buckle shell 1. A partition plate 11 is connected between the inner surfaces of the front and rear sides of the buckle shell 1. Two sets of engaging mechanisms 3 are symmetrically arranged at positions on both sides of the partition plate 11 inside the buckle shell 1. The engaging mechanism 3 includes a rotating shaft 304. Plug pins 305 are inserted at both the front and rear ends of the rotating shaft 304. An engaging plate 301 is rotatably sleeved on the outer surface of the rotating shaft 304. A pinch plate 306 is fixedly connected to the top of the engaging plate 301. A second hook 307 is fixedly connected to the outer surface of one side of the pinch plate 306. First hooks 2 are symmetrically and fixedly connected to positions on the inner surfaces of both sides of the buckle shell 1 near the lower part. A tension cord 21 is hooked between the first hook 2 and the second hook 307. The plug pin 305 is inserted on the outer surface of the buckle shell 1, and the end of the plug pin 305 penetrates the outer surface of the buckle shell 1 and extends into the interior. The engaging plate 301 is inclined and the bottoms of the two engaging plates 301 are close to each other. The pinch plate 306 is inclined and the pinch plate 306 and the engaging plate 301 are parallel. The tension cord 21 is in a contracted state.

[0023] The effect achieved by the entire Embodiment 1 is that when the device is in use, the thumb and index finger are used to pinch the two pinch plates 306 and apply force. At this time, under the action of the force, the upper ends of the pinch plates 306 will approach each other and transmit the force to the occlusal plate 301. At the same time, the second hook 307 will move along with the pinch plate 306 and cooperate with the first hook 2 to stretch the tension cord 21. At this time, the occlusal plate 301 will rotate around the rotation shaft 304. The bottom of the rotated occlusal plate 301 will move away from the partition plate 11, thus releasing the fixing effect on the elastic cord between the occlusal plate 301 and the partition plate 11. Then, the buckle shell 1 can be directly slid up and down outside the elastic cord to adjust. After adjusting to the appropriate position, release the pinch plate 306. At this time, the tension cord 21 will lose the pulling force and generate a pulling force to pull the second hook 307 to move directly above the first hook 2, so that the pinch plate 306 and the occlusal plate 301 are reset. The reset occlusal plate 301 will be inclined and its bottom will approach the partition plate 11 and then clamp the elastic cord again. The overall structure is small and convenient to use. The tightness of the elastic cord can be adjusted according to needs, ensuring the comfort and firmness after the elastic cord is fixed. There is a jack on the surface of the buckle shell 1 corresponding to the position of the plug pin 305. The plug pin 305 is designed in a three-section form. The end with the largest diameter is larger than the inner diameter of the jack and is located outside the buckle shell 1. The middle part is slightly smaller than the inner diameter of the jack and is located inside the jack. The diameter of the plug is smaller and is inserted at the end of the rotation shaft 304 to form the fixation of the rotation shaft 304 under the action of friction. When the plug pins 305 at both ends of the rotation shaft 304 are pulled out, the fixation of the rotation shaft 304 can be released. After separating the upper end of the tension cord 21 from the second hook 307, the occlusion mechanism 3 can be removed to replace the worn parts. The disassembly and assembly are convenient, facilitating the subsequent replacement of components, and having the effect of saving resources. The first hook 2 and the second hook 307 are mainly used for installing the tension cord 21.

[0024] Embodiment 2: As Figures 1-4 shown, anti-slip rubber pads 302 are adhesively connected to the outer surfaces of the opposite sides of the two pinch plates 306 near the top. The outer surface of the anti-slip rubber pad 302 is provided with anti-slip patterns, and the bottom of the occlusal plate 301 is provided with arc-shaped occlusal teeth 303.

[0025] The effect achieved by the entire Embodiment 2 is that when the device is combined with the elastic cord and then the two ends of the elastic cord are sewn to objects such as masks and face shields, the device cannot fall off, and the reliability is relatively high. By providing the occlusal teeth 303 at the bottom of the occlusal plate 301, after the elastic cord is clamped, the occlusal teeth 303 will be embedded in the elastic cord, increasing the firmness. At the same time, by adhering the anti-slip rubber pad 302 on the surface of the pinch plate 306, the effect of increasing the friction is achieved, facilitating the operation of pinching the pinch plate 306, and the soft anti-slip rubber pad 302 can improve the comfort of the fingers.

[0026] Working principle: When in use, pinch the two pinch plates 306 with the thumb and index finger and apply force. At this time, under the action of the force, the upper ends of the pinch plates 306 will approach each other and transmit the force to the bite plate 301. At the same time, the second hook 307 will move along with the pinch plate 306 and cooperate with the first hook 2 to stretch the tension cord 21. At this time, the bite plate 301 will rotate around the rotation axis 304. After rotation, the bottom of the bite plate 301 will move away from the partition plate 11, thus releasing the fixing effect on the elastic cord between the bite plate 301 and the partition plate 11. Then, the buckle shell 1 can be directly slid up and down outside the elastic cord for adjustment. After adjusting to the appropriate position, release the pinch plate 306. At this time, the tension cord 21 will lose the pulling force and generate a pulling force to pull the second hook 307 to move directly above the first hook 2, so that the pinch plate 306 and the bite plate 301 are reset. After resetting, the bite plate 301 will be inclined and the bottom will approach the partition plate 11 to clamp the elastic cord again. The overall structure is small and convenient to use. The tightness of the elastic cord can be adjusted according to needs, ensuring the comfort and firmness after the elastic cord is fixed. Moreover, when this device is combined with the elastic cord and then the two ends of the elastic cord are sewn to objects such as masks and face shields, this device cannot fall off, and the reliability is relatively high. By providing bite teeth 303 at the bottom of the bite plate 301, after the elastic cord is clamped, the bite teeth 303 will embed into the elastic cord, increasing the firmness. At the same time, by adhering an anti-slip rubber pad 302 on the surface of the pinch plate 306, the effect of increasing friction is achieved, facilitating the operation of pinching the pinch plate 306, and the soft anti-slip rubber pad 302 can improve the comfort of the fingers.

[0027] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
