Detailed Description
The core of the utility model is to provide a curve matching pull head, which can smoothly pass through the curve position of the zipper.
In order to make those skilled in the art better understand the technical solution of the present invention, the following will describe the curve matching slider and the zipper in detail with reference to the accompanying drawings and the specific embodiments.
As shown in fig. 2A, is an axonometric view of the curve-matching slider provided by the present invention; FIGS. 2B and 2C are side and front views, respectively, of a curve-matching pull head provided by the present invention; the utility model discloses a curve matching pull head includes upper plate 1 and lower plate 2, and the both sides of upper plate 1 set up the upside that spacing chain position kept off 3, and the both sides of lower plate 2 set up the downside that spacing chain position and keep off 4, keep off 3 and the downside through the upper side and keep off the cooperation of 4, make the chain of two separations gather together to the centre and realize the meshing. The front ends of the upper base plate 1 and the lower base plate 2 are connected through a fixing column 5.
The distance between the front part of the lower surface of the upper base plate 1 and the front part of the upper surface of the lower base plate 2 is gradually increased from back to front, the distance between the lower surface of the upper base plate 1 and the upper surface of the lower base plate 2 can be considered as the distance between the upper base plate 1 and the lower base plate 2, the front part can be considered as the part before the middle positions of the upper base plate 1 and the lower base plate 2, and can also be one third of the front end, and the specific position is correspondingly set as required.
As shown in figure 3, A represents a zipper, when the puller moves from left, the zipper is closed, because the distance between the front parts of the upper base plate 1 and the lower base plate 2 is larger, the zipper can be more attached to the shape of the curve, the puller can more smoothly pass through the curve, and the phenomenon of blocking is avoided.
On the basis of the scheme, the front end edge of the upper surface of the lower bottom plate 2 of the utility model is provided with a lower inclined surface 21 which inclines downwards from back to front, and the lower inclined surface gradually inclines downwards from left to right in figure 2B; as shown in fig. 2A and 2C, the lower inclined surface 21 is located between the lower side stop 4 and the fixing post 5, the length extending direction of the lower inclined surface 21 is the same as the shape of the edge of the lower base plate 2, and the portion of the lower base plate 2 located between the lower side stop 4 and the fixing post 5 is curved, so that the lower inclined surface 21 is also curved.
The slope of the lower inclined surface 21 is greater than that of the upper surface of the lower base plate 2, and the upper surface of the lower base plate 2 can be regarded as approximately horizontal, and the slope is zero. The upper surface and the lateral wall of traditional pull head structure lower plate 2 are 90 degrees contained angles, adopt the structure setting of inclined plane 21 down, can be more close to the curve appearance. As shown in fig. 2B, the longitudinal section of the lower inclined surface 21 is arc-shaped, and the lower inclined surface 21 is a convex surface that is slightly convex upward, but a configuration in which the longitudinal section is linear is also possible.
Furthermore, the lower bending surface 22 is obliquely and downwardly arranged at the front part of the upper surface of the lower bottom plate 2 from back to front, the lower inclined surface 21 is positioned in front of the lower bending surface 22, and the slope of the lower bending surface 22 is smaller than that of the lower inclined surface 21, namely, the plane part of the upper surface of the lower bottom plate 2 and the lower inclined surface 21 are provided with transitional lower bending surfaces, and the transition is gradually from the plane to the lower inclined surface 21, so that a smoother fit guiding effect can be realized.
In order to match different conditions, the utility model is provided with an upper inclined plane 11 at the front end edge of the lower surface of the upper bottom plate 1 from back to front in an inclined manner, and the upper inclined plane 11 is positioned between the upper side baffle 3 and the fixed column 5; the slope of the upper slope 11 is greater than the slope of the lower surface of the upper plate 1. The structure of the upper inclined plane 11 is similar to that of the lower inclined plane, and is suitable for the curved condition of different orientations of the zipper, as shown in fig. 3, when the zipper A is bent upwards, the zipper A can be contacted with the upper inclined plane 11.
The upper inclined plane 11 and the lower inclined plane 21 may exist at the same time, or only one of them may be provided, and an appropriate arrangement scheme is selected according to different use conditions.
Specifically, the inclination angle of the middle lower inclined plane 21 of the utility model is 10-60 degrees, i.e. the included angle between the middle lower inclined plane and the horizontal plane is 10-60 degrees, and the middle lower inclined plane comprises two end points; likewise, the upper inclined surface 11 is also set to the same inclination angle range.
On the basis of any above-mentioned technical scheme and intercombination, the utility model discloses the interval at the rear portion of upper and lower bottom plate 1 lower surface and 2 upper surface rear portions of lower plate is crescent backward in the past, when the pull head is reverse through the curve, also pulls open the in-process, and the rear portion of pull head is earlier through the curve, and the rear portion sets up the structure that upper plate 1 and 2 intervals of lower plate crescent backward in the past, can make things convenient for reverse pulling, can realize the same technological effect with the corresponding structure of above-mentioned front portion setting.
Because the upper base plate 1 and the lower base plate 2 at the rear part need to be pressed together with two chains, the distance increase amplitude of the rear part is smaller than that of the front part, and the dislocation of the chains is avoided.
Correspondingly, a lower rear inclined surface is obliquely and downwardly arranged from front to back at the rear end edge of the upper surface of the lower bottom plate 2, and the lower rear inclined surface is positioned between the lower side baffles 4 at two sides. The lower rear slope is arranged in a similar manner to the lower slope 21, but with a slope that is less than the slope of the lower slope 21.
The rear end edge of the lower surface of the upper bottom plate 1 is obliquely and upwards provided with an upper rear inclined plane from front to back, and the upper rear inclined plane is positioned between the upper side baffles 3 at two sides. The upper rear slope is similar to the upper slope 11, but the slope is smaller than that of the upper slope 11.
On the basis of any one of the technical schemes and the mutual combination thereof, as shown in fig. 2C, the front part of the upper surface of the lower bottom plate 2 is gradually inclined downwards from the middle to two sides, one side close to the fixing column 5 is higher, the height of the upper surface at two sides is lower, and as the two chains are in a certain opening angle in the zipper closing process, the structure with the middle higher and two sides lower can be more smoothly matched with the entering direction of the chains.
The utility model also provides a zip fastener, including foretell curve matching pull head, this zip fastener can realize level and smooth effect through the curve.
