Description

Technical Field

[0001] The utility model relates to the technical field of zipper structures, in particular to a metal easy-to-start slider. Background Art

[0002] As a connecting component for opening and closing zippers, zipper pullers have been widely used in purses and clothing due to their convenient operation. The design and structure of pullers vary, but they are generally composed of five parts: cap, spring, hook, pull tab, and inner cavity body. Traditional pullers on the market use the size of the zipper guide cavity to control the zipper teeth according to the size of the zipper, and then use part of the puller structure (cap, spring) to unlock and start. However, according to market research, some pullers use puller accessories (the curvature of the spring) to control the opening and closing of the zipper, which generally have the following defects:

[0003] (1) The chamfer of the existing metal zipper guide cavity is too small. When the zipper teeth are flipped instead of vertical, the pull head will be stuck by the teeth. The zipper is easy to get stuck after starting or locking the chain. The smoothness is relatively poor and it cannot be pulled normally.

[0004] (2) The existing structure of the pull head cannot slide normally when the zipper teeth are turned over, which makes the zipper limited in the style of ready-made clothes and cannot better serve the fashionable and diversified designs generated by the growing spiritual needs of the people today;

[0005] (3) Most existing cap designs adopt a cutout fixing method, which is not only cumbersome to install and fix, but also has poor stability. In addition, its design structure is unreasonable and only serves to fix the pull tab, making the inner hook spring easy to fall off, affecting production efficiency and product quality;

[0006] (4) Most existing horse hooks adopt a bent spring structure, which has weak strength and is prone to instability after long-term use, thereby affecting product quality. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See attached Figure 1-5 ;

[0030] A metal easy-to-start slider comprises a slider body, the slider body comprises a top plate 1 and a bottom plate 2 which are interconnected by a connecting portion, a zipper guide cavity 3 is formed between the top plate 1 and the bottom plate 2 and the connecting portion, chamfers 4 are respectively provided on the top plate 1 and the bottom plate 2 at the front and rear ends of the zipper guide cavity 3, the angle of the chamfer 4 is 2-10°, and the chamfers of the top plate 1 and the bottom plate 2 cooperate with each other to form a trumpet-shaped inlet and outlet of the zipper guide cavity 3, two spaced-apart clamping seats 1 5 and 6 for clamping and fixing a dot-marking cap 10 are provided in the middle of the upper end of the top plate 1, and the clamping seat 2 6 is located at the rear, and a horse hook groove 7 connected to the zipper guide cavity 3 is provided in the middle thereof, a horse hook 8 is also clamped on the clamping seat 1 5, and the rear end of the horse hook 8 extends into the zipper guide cavity 3 through the horse hook groove 7 and can move up and down.

[0031] Among them: the cap design abandons the traditional cutting fixation method and adopts advanced dotting fixation technology to ensure that the spring piece is stable and not easy to fall off during the production and assembly process, thereby significantly improving production efficiency, reducing material loss, and reducing human resource investment. Compared with traditional sliders, this design significantly reduces the defective rate and improves product quality.

[0032] The front and rear ends of the top and bottom plates adopt a precisely designed chamfered bell-mouth structure (the chamfer angle is 2-10°, which is obtained through experiments. The range meets the chamfering requirements of all sliders to ensure smoothness during the pulling and closing process. The value within the angle range can be adjusted appropriately according to the specifications of the slider and the thickness of the top and bottom plates). This innovative design helps to reduce friction resistance when the chain teeth slide in the zipper guide cavity, and can effectively avoid jamming even when the chain teeth are uneven. At the same time, the design also saves material costs; compared with traditional sliders, the upper and lower bottom plates without chamfers will generate additional resistance when the chain teeth slide, and uneven chain teeth are more likely to cause jamming.

[0033] Furthermore, the chamfer 4 is an arc-shaped chamfer. The connection between the connecting portion and the top plate 1 and the bottom plate 2 is provided with transition chamfers 9 respectively.

[0034] Further, the first clamping seat 5 includes a seat body 51, the front end of the seat body 51 is provided with a T-shaped seat body 52 for clamping the front end of the cap, the front end of the T-shaped seat body 52 is provided with a clamping limit cavity 1 on both sides, the rear end of the seat body 51 is provided with a clamping cavity 53, and the rear end is provided with a wedge block 54 that is obliquely arranged and extends to both sides, and one side of the wedge block 54 is provided with a hook 55 that protrudes upward. The second clamping seat 6 is a matching structure with the first clamping seat 5, and includes a second seat body, the rear end of the second seat body is provided with a T-shaped seat body 2 for clamping the rear end of the cap, the rear end of the T-shaped seat body 2 is provided with a clamping limit cavity 61 on both sides, the front end of the T-shaped seat body 2 is provided with a horse hook groove 7 corresponding to the hook 1, and the front end is provided with a wedge block 62 that is obliquely arranged and extends to both sides, and one side of the wedge block 62 is provided with a hook 63 that protrudes upward, and the hook 63 is staggered with the hook 1 55. The width dimensions of wedge 1 54 and wedge 2 62 match the width dimension of the cap.

[0035] Furthermore, the hook 8 is an arched structure, with a hook portion 81 engaged with the hook 1 at the front end thereof, a brake hook 82 engaged with the hook groove 7 and used to lock or unlock the zipper operation at the lower rear end thereof, and a hook stopper 83 cooperating with the stopper cavity at the rear end of the hook groove 7 at the rear end of the hook 8. The structural design of the hook abandons the traditional bending method of the spring sheet, ensuring that the force remains consistent when the pull sheet is not lifted, thereby achieving the stability and efficiency improvement of the production process; compared with the design of the traditional slider spring sheet that needs to be bent, this design avoids the problems of unstable quality and low efficiency caused by factors such as the size of the bending arc.

[0036] The utility model changes the zipper guide cavity structure (i.e., a suitable chamfer angle is provided for the zipper guide cavity) and the connection method between the cap and the body (i.e., instead of penetrating the slider to make a notch, a dot is made on the cap) on the basis of an ordinary slider structure, so that the slider has the same starting quality at different angles and arcs of the zipper teeth, thereby allowing the slider to move smoothly along the zipper teeth, while also solving the problem of obvious jamming behind the chain, greatly improving the smoothness and usability of the zipper and enhancing the usability of the garment.

[0037] The design principle of the improved structure is analyzed as follows:

[0038] 1. Transformation and upgrading of the inner cavity structure:

[0039] After many tests and precision improvements, the inner cavity of this slider has been carefully upgraded. Specifically, the front and rear ends of the inner cavity adopt a carefully designed chamfered trumpet-shaped structure (including precise angle data). This design is designed to ensure that the friction resistance between each chain tooth and the inner cavity can be significantly reduced when the zipper slides in the zipper guide cavity. At the same time, this chamfered trumpet-shaped design can also effectively solve the problem that when the chain teeth are blocked by sewing to the fabric, they can easily enter the zipper guide cavity smoothly through the trumpet mouth, thereby greatly reducing the jamming phenomenon caused by the obstruction of the chain teeth.

[0040] 2. Optimization of accessories structure:

[0041] The key accessories of the slider (cap, spring) have also been optimized and upgraded. In particular, the cap uses a minimal dotting method to fix the spring to ensure that the strength of the spring is always consistent during the assembly process. This design ensures that the horse hook can move up and down freely during use, and the pull tab behind the chain makes it easier to lift the horse hook, providing consumers with a more convenient and smooth use experience.

[0042] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0043] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
