Description

Technical Field

[0001] The utility model relates to a webbing easy-pull buckle. Background Art

[0002] An easy-pull buckle is a telescopic device with a built-in spring reel for manual stretching. Common names in China also include telescopic buckle, easy-pull, ID card buckle, etc. When the existing easy-pull buckle is used in cooperation with a hanging strap, usually only one notch for the webbing to pass through is provided on the easy-pull buckle. When the webbing is hung around the neck, usually the width surface of the webbing contacts the neck, so that in the natural state, the side in the thickness direction of the webbing will face forward, and thus the easy-pull buckle also faces forward on the side, and the situation where the front of the easy-pull buckle faces forward cannot be achieved, affecting the aesthetic effect when the webbing and the easy-pull buckle are worn.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] To make the above features and advantages of the present utility model more understandable, specific embodiments are given below in conjunction with the accompanying drawings for detailed description. However, the present utility model is not limited thereto.

[0025] Embodiment 1 Refer to Figure 1

[0026] A webbing easy-pull buckle includes an easy-pull buckle housing 1 installed with a telescopic rewinding assembly 2. The upper part of the easy-pull buckle housing has a webbing connection part 11 that protrudes upward and is integrally formed. A webbing passing groove 12 for the longitudinal passing of the webbing is horizontally opened on the webbing connection part. Two webbing folding outlets 13 that are vertically opened on the upper end surface of the webbing connection part and are horizontally offset and communicate with the webbing passing groove are provided, so that both ends of the webbing 3 are folded into a V shape after passing through the webbing folding outlets, so as to ensure that the front side of the easy-pull buckle faces forward when the webbing is worn on the chest.

[0027] Embodiment 2 Refer to Figures 1 to 6

[0028] A webbing easy-pull buckle includes an easy-pull buckle housing 1 installed with a telescopic rewinding assembly 2. The upper part of the easy-pull buckle housing has a webbing connection part 11 that protrudes upward and is integrally formed. A webbing passing groove 12 for the longitudinal passing of the webbing is horizontally opened on the webbing connection part. Two webbing folding outlets 13 that are vertically opened on the upper end surface of the webbing connection part and are horizontally offset and communicate with the webbing passing groove are provided, so that both ends of the webbing 3 are folded into a V shape after passing through the webbing folding outlets, so as to ensure that the front side of the easy-pull buckle faces forward when the webbing is worn on the chest.

[0029] In this embodiment, in order to better fix the webbing into a V-shaped extension, a separation structure 14 located between the two webbing folding outlets has an extension part 141 that extends downward into the webbing passing groove, and there is a gap 121 for the webbing to pass through between the lower end of the extension part and the bottom surface of the webbing passing groove.

[0030] In this embodiment, the length of the extension part extending downward accounts for more than 1 / 2 of the height of the webbing passing groove. Both the front and rear sides of the lower end of the extension part have protruding parts to form a structure similar to an inverted T shape, so that both ends of the webbing can be better clamped after passing through the webbing folding outlets, avoiding the displacement of the webbing and playing the role of a fixing rod.

[0031] In this embodiment, the easy-pull buckle housing includes a front cover 15 and a rear cover 16. Both the front cover and the rear cover are made of plastic, such as ABS material. The front cover is buckled on the rear cover and fixed into one body by ultrasonic welding, so that a telescopic rotary assembly installation chamber is formed between the front cover and the rear cover.

[0032] In this embodiment, the webbing connection part is arranged on the upper part of the rear cover, and the telescopic rewinding assembly is installed in the rear cover.

[0033] In this embodiment, the telescopic rewinding component includes a disc 21 rotatably connected inside the easy-pull buckle housing. Specifically, the disc is installed inside the rear cover. A fixed shaft 17 rotatably connected to the disc is fixed inside the rear cover. A card slot 171 is provided on the fixed shaft. One end (inner ring end) of a torsion spring 22 installed on the inner ring of the disc is fixedly connected to the card slot by clamping, and the other end (outer ring end) of the torsion spring is fixedly connected to the disc by clamping. A pull rope 23 is wound around the outer ring of the disc. One end of the pull rope is fixed to the disc, and the other end of the pull rope passes through the easy-pull buckle housing and is installed with a connecting piece. An item for hanging a work permit is carried out through the connecting piece.

[0034] Specifically, in order to make the pull rope better drawn and protect the pull rope, a pull rope outlet 18 is provided at the bottom of the easy-pull buckle housing and a wire protection sleeve 24 is installed. The other end of the pull rope passes through the wire protection sleeve and is connected to the connecting piece. The connecting piece is composed of a hanging piece 25 and a hanging ring 26 installed on the hanging piece. The pull rope is prevented from being completely retracted into the easy-pull buckle housing through the hanging piece, and an item to be hung is installed through the hanging ring.

[0035] When the webbing is installed, the webbing 3 passes through the gap 121 of the webbing slot 12, and then the two ends of the webbing 3 are respectively passed through and tightened from two shaped winding outlets 13 on the rear cover 16, so that the webbing fits the lower end of the extension part, thereby forming a V shape for the webbing. The two ends of the webbing can be connected into one body through a fixing piece, or can be integrally formed by in-mold injection casting through a fixing piece.

[0036] If the present utility model discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), or can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integral structure (for example, manufactured by integral forming using a casting process) (except when it is obviously impossible to adopt the integral forming process).

[0037] In addition, the terms used to represent the positional relationship or shape in any of the technical solutions disclosed in the present utility model described above, unless otherwise stated, include states or shapes that are approximate, similar, or close to it.

[0038] Any component provided by the present utility model can either be assembled from a plurality of separate components or be a single component manufactured by an integral forming process.

[0039] The above are only the preferred embodiments of the present utility model. All equivalent changes and modifications made according to the scope of the patent application of the present utility model shall fall within the scope covered by the present utility model.
