Detailed Description

Specific embodiments of the present utility model will be described below with reference to the accompanying drawings. Numerous details are set forth in the following description in order to provide a thorough understanding of the present utility model, but it will be apparent to one skilled in the art that the present utility model may be practiced without these details.

Embodiment one:

referring to fig. 1 to 3, a safety insert buckle type slider includes a first slider 1 and a second slider 2, the first slider 1 is provided with a first pull tab 3, the second slider 2 is provided with a second pull tab 4, the first pull tab 3 is provided with an insert buckle 32 with an elastic pin 31, and the second pull tab 4 is provided with an insert buckle cavity 41 for accommodating the insert buckle 32 and is provided with a pressing claw 42 abutted against the elastic pin 31. Specifically, the safety insert buckle type slider provided by the utility model is suitable for a double-slider zipper, so that the first slider 1 and the second slider 2 refer to two sliders which are oppositely arranged on the same zipper strip. The pull tabs on the two pull tabs are mutually buckled in a plugging buckle mode, and the elastic pin of one pull tab is abutted with the pressing claw of the other pull tab during buckling, so that the buckling is ensured to be firm and not to fall off.

Referring to fig. 1 to 3, the middle part of the second pull tab 4 is provided with a buckle inserting cavity 41 adapted to the outline of the buckle inserting 32, and is hollowed out along two side edges of the buckle inserting cavity 41 to form a pressing claw 42. Under the lock state, second pull tab 4 wraps up first pull tab 3 in, and this structural style presents better visual effect to can prevent that the zip fastener from sliding open by oneself after closing, have simple and easy theftproof function simultaneously. When in use, one hand presses the pressing claw 42 of the second pull tab 4, so that the pressing claw 42 generates elastic deformation and further presses the elastic pin 31 to generate elastic deformation together, and the elastic pin 31 is contracted into the eye-splice cavity 41; the other hand pulls out the first pull tab 3 in the opposite direction, and pulls out the insert buckle 32 from the insert buckle cavity 41, so that the first pull tab 3 and the second pull tab 4 can be released from the buckling state.

Referring to fig. 1 to 3, a first slider 3 is provided to a first slider 1 in a reversible manner, and a second slider 4 is provided to a second slider 2 in a reversible manner. The front end of the first pull head 1 is provided with a first inclined table 13 for limiting the turning angle of the first pull piece 3, and the front end of the second pull head 2 is provided with a second inclined table 23 for limiting the turning angle of the second pull piece 4. In this embodiment, the front end of the slider is used to close one end of the slide fastener in a top view, and the rear end of the slider is used to open one end of the slide fastener in a top view. The free ends of the first pull tab 3 and the second pull tab 4 are turned over toward the front ends by the rear ends of the first pull tab 1 and the second pull tab 2, respectively, so that the first ramp 13 and the second ramp 23 are disposed at the front ends of the boarding plates of the first pull tab 1 and the second pull tab 2, respectively, thereby preventing the pull tab from being turned excessively.

Referring to fig. 1 to 3, the present embodiment defines that the turning angles of the first pull tab 3 and the second pull tab 4 are all 0 ° -135 °, and when the first pull tab 3 and the second pull tab 4 are turned to the horizontal position, the insert buckle 32 of the first pull tab 3 is inserted into the insert buckle cavity 41 of the second pull tab 4, so that the elastic pin 31 abuts against the pressing claw 42, thereby forming a locked state.

Referring to fig. 1 to 3, the first slider 1 is provided with a first pivot seat 11, and the first slider 3 is rotatably provided to the first slider 1 by a first fitting pin 12 in cooperation with the first pivot seat 11; the second slider 2 is provided with a second pivot seat 21, and the second pull tab 4 is arranged on the second slider 2 in a reversible manner by matching with the second pivot seat 21 through a second assembly bolt 22. The pull head and the pull piece adopt a connection mode that the pivot seat is matched with the assembly bolt, and the connection mode can strengthen the connection firmness and reliability between the pull piece and the pull head in the overturning process.

Referring to fig. 1 to 3, the lower ship plate of the first slider 1 and the lower ship plate of the second slider 2 are provided with an extension portion 5 at opposite positions, so that a gap between the two sliders is shielded, a certain covering effect is achieved on the exposed articles, and the risk of accidental scattering or exposure of the articles is effectively reduced.

Embodiment two:

referring to fig. 4, unlike the first embodiment, the lower plate of the first slider 1 and the lower plate of the second slider 2 are not provided with an extension.

Compared with the first embodiment, the present embodiment can be applied to some small zippers in daily life, because the teeth on the small zippers are generally arranged tightly, and the structure of the sliders is also more compact, so that the gap between two sliders arranged in opposite directions is smaller, and the extension part is not required to be arranged for shielding. Of course, whether the extension is designed is also related to the size of the first pull tab 3 and the second pull tab 4, and also related to the use scene of the double-slider zipper and the specific requirements of the customer, so that whether the extension is set can be flexibly selected according to the specific situation in practical application.

The foregoing is merely illustrative of specific embodiments of the present utility model, but the design concept of the present utility model is not limited thereto, and any insubstantial modification of the present utility model by using the design concept shall fall within the scope of the present utility model.
