Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a zipper head adaptable to different pull tabs. Background Art

[0002] A zipper consists of chain elements, a slider, and upper and lower stops or locking parts. Generally, a zipper has two chain straps, each with a row of chain elements, and the two rows of chain elements are staggered. The slider, also known as the zipper head, is the moving part that slides along the zipper strap to engage and disengage the chain elements. The zipper head clamps the chain elements on both sides and slides with the help of the pull tab to engage and disengage the chain elements.

[0003] In an existing zipper slider, the distance between the cover member and the upper wing plate is small. After electroplating, the gap between the cover member and the wing plate is easily connected by the plating layer, causing jamming. For example, the zipper slider disclosed in Chinese Patent Publication No. CN103702583A has a small gap between the downwardly extending protrusion provided on the cover member and the upper wing plate, which is easily connected into one piece by electroplating during electroplating, causing structural jamming. In addition, the protruding protrusion may catch on clothes during washing, causing the slider or clothes to be damaged. Utility Model Content

[0018] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] It should be noted that all directional indications in the embodiments of the present invention (such as up-down-left-right-front-back...) 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. The connection can be a direct connection or an indirect connection.

[0021] like Figure 1-Figure 3 As shown, a zipper head adapted to different pull tabs includes a slider body 1, a cap 2, a locking member 3, a spring piece 4, and a pull tab 5. The slider body 1 includes an upper wing plate 11, a guide post 12, and a lower wing plate 13. The guide post 12 is fixedly connected between the upper wing plate 11 and the lower wing plate 13. The cap 2 includes a fixing portion 21 and a cantilever portion 22. The fixing portion 21 is fixedly connected to the upper wing plate 11. The cantilever portion 22 is fixedly connected to the fixing portion 21 and suspended on the upper wing plate 11. The cantilever portion 22 An inward-concave groove 23 is provided in the middle, the upper end of the locking member 3 is located in the groove 23, a spring piece 4 is clamped between the locking member 3 and the inner wall of the cantilever portion 22, and the bottom of the cantilever portion 22 away from the fixing portion 21 is a flat structure; a rubber plug 6 is clamped on the upper wing plate 11, and the pull tab 5 includes a connecting shaft 51, which is located in the accommodating space 7 enclosed by the cap 2 and the upper wing plate 11. The upper end of the rubber plug 6 is arranged opposite to the cantilever portion 22 to confine the connecting shaft 51 in the accommodating space 7.

[0022] By adopting the above technical solution, the bottom of the cantilever portion 22 of the cap 2 is set to a flat structure to avoid hooking on clothes. The cap 2 is fixedly connected to the upper wing plate 11 through the fixing portion 21, thereby improving the connection strength of the cap 2. As a result, the space for accommodating the pull tab 5 can be increased under the same connection strength, and pull tabs 5 of different sizes can be assembled to adapt to the installation of different pull tabs 5, so that different pull tabs 5 can be selected as needed.

[0023] Specifically, the upper wing plate 11 is provided with a limiting groove 14, and the two sides of the rubber plug 6 are provided with outwardly extending flanges 61, and the flanges 61 are inserted into the limiting groove 14. When fixing the rubber plug 6, the rubber plug 6 is pushed into the limiting groove 14 from the end thereof, thereby facilitating the positioning of the rubber plug 6.

[0024] Specifically, the rubber plug 6 is provided with an upwardly protruding inclined block 62. The end of the inclined block 62 near the fixed portion 21 is elastically connected to the rubber plug 6. The upper end of the inclined block 62 is inserted into the groove 23 of the cantilever portion 22. After the pull tab 5 is installed, it cannot be removed from between the inclined block 62 and the cantilever portion 22. By providing the inclined block 62 on the rubber plug 6, after the inclined block 62 is inserted into the groove 23, the inclined block 62 bounces upward and is restrained in the groove 23, thereby locking the rubber plug 6 on the upper wing plate 11 and further locking the pull tab 5 in the receiving cavity of the cap 2. During disassembly, the inclined block 62 is pressed downward to pull out the rubber plug 6, and then the pull tab 5 can be removed for replacement, thereby facilitating replacement of the pull tab 5.

[0025] Specifically, the tilting block 62 is provided with an inclined surface 63, which is inclined toward the upper wing plate 11 at the end near the pull tab 5. When the rubber plug 6 is installed, when it is pushed into the upper wing plate 11 from the limiting groove 14, the cantilever portion 22 contacts and presses the inclined surface 63, causing the tilting block 62 to elastically deform downward. After the inclined surface 63 slides along the end of the cantilever portion 22 into the groove 23, the tilting block 62 springs upward and snaps into the groove 23, thereby facilitating the installation of the rubber plug 6.

[0026] Specifically, a hinge part 15 is fixedly connected to the upper wing plate 11, and the upper surface of the hinge part 15 is an arc-shaped structure. The locking member 3 includes a rotating part 31 and a locking part 32 fixed in the middle of the rotating part 31. An avoidance groove 16 that passes through the upper wing plate 11 is opened in the middle of the upper wing plate 11, and the lower end of the locking part 32 extends into the avoidance groove 16. A first arc groove 311 and a second arc groove 312 are provided on the rotating part 31. The first arc groove 311 is stuck on the hinge part 15, and the connecting shaft 51 is located in the second arc groove 312. The spring piece 4 abuts against the upper end of the rotating part 31 so that the rotating part 31 rotates toward the lower wing plate 13 so that the locking part 32 passes through the avoidance groove 16 and is stuck between the chain teeth. The first arc groove 311 cooperates with the hinge part 15, so that the locking member 3 can rotate, and the elastic force provided by the spring piece 4 makes the locking part 32 of the locking member 3 get stuck between the chain teeth of the zipper, thereby locking the zipper head; when the zipper head needs to be moved, the pull tab 5 is pulled upward to overcome the elastic force of the spring piece 4, so that the locking member 3 rotates away from the upper wing plate 11, thereby driving the locking part 32 to disengage from the chain teeth, and then the zipper head can be moved.

[0027] Specifically, the upper surface of the cap 2 is arc-shaped, so as to avoid scratching clothes at right angles and facilitate use.

[0028] The parts not involved in this technical solution can be implemented using existing technologies.

[0029] The above shows and describes the basic principles, main features, and characteristics of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
