Description

Technical Field

[0001] The invention relates to the field of zippers, in particular to a side-entry opening zipper. Background Art

[0002] The lid and the body of the bag are connected by a zipper. There are currently two structures:

[0003] One is that the ends of the zipper are sewn shut with sewing thread. With this structure, if there are partial defects in the zipper during the production of luggage, it will be scrapped or the rework cost will be huge.

[0004] One is an open zipper with an interlaced structure. With this structure, when a zipper is defective, the box cover and the box body can be separated and replaced, so the problem of production defects can be solved. However, in actual use, the following problems arise:

[0005] 1. The traditional open zipper is composed of a fixed pin and a plug. The zipper slider is placed on the fixed pin, and then the plug is passed through the slider and positioned on the fixed pin. Then the slider is pulled to close the zipper. That is, the plug must pass through the slider from above and insert into the fixed pin, and the plug must contact the bottom of the fixed pin to complete the positioning before the slider can be pulled.

[0006] 2. The docking line between the lid and the body of the luggage is connected by a zipper seal. Because the luggage is designed to use a zipper, both ends of the zipper must have fixed pins, that is, a double-headed zipper. Therefore, when one end of the zipper is positioned, the position of the other end of the zipper is restricted. Therefore, when operating the insertion, the first pin can be inserted normally, but the second pin will be affected by the limit of the first pin that has been positioned. As a result, the zipper must be pulled so that the second pin can pass through the slider and be positioned on the fixed pin. Here, for the zipper that has been installed on the luggage, the operating space is very narrow and not easy to use. If it is not done properly, the zipper is easy to be damaged, which is inconvenient to use. Summary of the invention

[0007] The present invention provides a side-entry opening zipper, the purpose of which is to solve the shortcomings of the prior art. The user can conveniently separate the box cover and the box body, reduce the cost of replacing the zipper defects in production, and the zipper can be used conveniently.

[0008] The technical solution adopted by the present invention to solve its technical problem is:

[0009] Side entry zipper, characterized by:

[0010] A lower latching slot is provided inside the fixing pin, and an opening of the lower latching slot is located at the lower part of the fixing pin and faces the side of the opposite zipper;

[0011] The lower latch slot is composed of two parts: a latch lower slot located on the outside and a cross pin slot located on the inside;

[0012] The inner side of the slot at the lower part of the latch is provided with a baffle;

[0013] A horizontal pin extends outward from the lower part of the latch;

[0014] The fixing pin is fixed on the left zipper with the left chain belt, and the slider is combined with the left chain belt and is pressed on the top of the fixing pin;

[0015] The fixing pin is fixed to the right zipper with the right chain strap;

[0016] When the fixed pin and the latch pin are combined, the latch pin lower portion of the latch pin is accommodated in the latch pin lower portion slot, and the cross pin is accommodated in the cross pin slot;

[0017] Both the left and right chain straps go into the slider.

[0018] An upper latch pin slot is arranged on the inner side of the upper part of the fixing pin. When the fixing pin and the latch pin are combined, the body of the latch pin is inserted into the upper latch pin slot.

[0019] The upper latch pin slot is a sunken step space opened on the inner side of the upper part of the fixing pin.

[0020] A protrusion extends outward from the upper part of the latch, and the lower surface of the protrusion has a downward inclined surface facing the opposite zipper; the upper surface of the fixing pin has an upward inclined surface facing the opposite zipper; when the fixing pin and the latch are combined, the inclined surface of the protrusion matches the inclined surface of the fixing pin.

[0021] The fixing pin and the latch pin are respectively provided with a plurality of mounting holes for passing the fixing wires and fastening them to the cloth.

[0022] The transverse pin slot is composed of a cylindrical lower transverse pin slot and an upper transverse pin slot inclined toward the opposite zipper, and the transverse pin is composed of a cylindrical lower transverse pin and an inclined upper transverse pin.

[0023] When the fixing pin and the plug pin are combined, the cylindrical lower transverse pin is accommodated in the cylindrical lower transverse pin slot, and the inclined upper transverse pin is accommodated in the inclined upper transverse pin slot.

[0024] Two fixing pins are fixed on the left zipper with the left chain belt, and two sliders are combined with the left chain belt and respectively supported on the two fixing pins; two latch pins are fixed on the right zipper with the right chain belt.

[0025] The present invention is beneficial in that:

[0026] The present invention is a side-entry zipper. Since the fixing pin and the latch pin are separated, the two chain belts of the zipper are separated, so the box body and the box cover can be easily disassembled. If there is a problem with a part of the upper and lower parts of the box body and the box cover, the problematic part can be replaced separately, and the replacement is simple.

[0027] And because the latch can be positioned on the fixed pin from the side, bypassing the slider, after positioning, the slider can be pulled to use it normally. When it is a double-head zipper, the two latches will not affect each other, which is very convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

The terms "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate an orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", "third", etc., etc. are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0042] like Figure 1 As shown:

[0043] An upper pin slot 14 is provided on the inner side of the upper part of the fixing pin 1 (the upper part is the direction toward the zipper connected to the fixing pin 1, and the inner side is the direction toward the inside of the object on which the zipper is installed, such as clothes or bags). The upper pin slot 14 of this embodiment is a sunken step space opened on the inner side of the upper part of the fixing pin 1.

[0044] The upper surface of the fixing pin 1 has an upwardly inclined surface 15 facing the opposite zipper.

[0045] An opening 13 is provided on the side of the lower part of the fixing pin 1 facing the opposite zipper (that is, the right side in the view), and the opening 13 is the opening of the lower latch pin slot provided inside the fixing pin 1 (consisting of two parts: a lower latch pin slot opening 131 and a cross pin slot opening 132). The lower latch pin slot consists of two parts: a lower latch pin slot 11 located on the outside (the opening is the lower latch pin slot opening 131) and a cross pin slot 12 located on the inside (the opening is the cross pin slot opening 132).

[0046] A baffle 111 is provided on the inner side of the lower insertion slot 11 of the latch.

[0047] The transverse pin slot 12 is composed of a cylindrical lower transverse pin slot 121 and an upper transverse pin slot 122 inclined toward the opposite zipper.

[0048] The fixing pin 1 is provided with a plurality of mounting holes 10 for passing the fixing wires to be fastened to the fabric.

[0049] like Figure 2 As shown:

[0050] A protrusion 25 extends outward from the upper portion of the latch 2, and the lower surface of the protrusion 25 has a downward inclined surface 251 facing the opposite zipper (ie, the left side in the view).

[0051] A transverse pin 22 extends outward from the lower portion of the latch 2. The transverse pin 22 is composed of a cylindrical lower transverse pin 221 and an inclined upper transverse pin 222.

[0052] The latch 2 is provided with a plurality of mounting holes 20 for passing the fixing wires to be fastened to the fabric.

[0053] like Figure 3 As shown:

[0054] Insert the latch 2 into the fixing pin 1 from the side, align the lower portion of the latch 2 with the lower latch slot opening 131 of the lower latch slot 11, and then insert it while rotating. In this way, the lower portion of the latch 2 is inserted into the lower latch slot 11 from the lower latch slot opening 131, and the cross pin 22 of the latch 2 is inserted into the cross pin slot 12 from the cross pin slot opening 132.

[0055] Finally, the lower part of the latch 2 is accommodated in the lower latch slot 11, and the cross pin 22 is accommodated in the cross pin slot 12, wherein the cylindrical lower cross pin 221 is accommodated in the cylindrical lower cross pin slot 121, and the inclined upper cross pin 222 is accommodated in the inclined upper cross pin slot 122.

[0056] Such a structure facilitates the insertion of the lower portion of the latch into the lower latch slot 11 from the side, and the inclined upper transverse pin 222 facilitates the insertion of the transverse pin 22 into the transverse pin slot 12. After insertion, the baffle 111 blocks the latch 2 from moving inward, and the entire latch 2 is blocked from moving inward, outward, upward, and downward directions, and is connected to the fixed pin 1.

[0057] The body of the latch 2 is inserted into the upper latch slot 14, and the inclined surface 251 on the lower surface of the protrusion 25 cooperates with the upward inclined surface 15 on the upper surface of the fixed pin 1. The inclined inclined surface cooperates to facilitate the insertion of the latch 2 into the fixed pin 1 from the side. After insertion, the above structure limits the outward and downward movement of the latch 2.

[0058] Thereby, the latch pin 2 and the fixing pin 1 are connected together.

[0059] like Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown:

[0060] This embodiment is a case of a single-head zipper.

[0061] The fixing pin 1 is sewn and fixed on the cloth 41 of the left zipper (it can also be on the box body), and the left chain belt 51 of the left zipper is also sewn and fixed on the cloth 41 of the left zipper.

[0062] The slider 3 is combined with the left chain belt 51 and is pressed against the top of the fixing pin 1 .

[0063] The latch 2 is sewn and fixed on the cloth 42 of the right zipper (or on the box cover), and the right chain belt 52 of the right zipper is also sewn and fixed on the cloth 42 of the right zipper.

[0064] When you need to zip:

[0065] Insert the latch pin 2 into the fixing pin 1 from the side and combine them together. At this time, the left chain belt 61 and the right chain belt 62 enter the slider 3. Pull the slider to combine the left chain belt 51 and the right chain belt 52.

[0066] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown:

[0067] This embodiment is a double-ended zipper.

[0068] Different from the above-mentioned single-head zipper, there are fixing pins 1, latch pins 2 and sliders 3 at both ends of the zipper.

[0069] When you need to zip:

[0070] Insert the latch pins 2 at both ends into the fixing pins 1 from the side to assemble them together. At this time, the left chain belt 61 and the right chain belt 62 enter the slider 3. Pull the slider to combine the left chain belt 51 and the right chain belt 52.

[0071] In this case, the combination actions of the two latches 2 and the fixing pin 1 will not affect each other, and the use is convenient.

[0072] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the embodiments can be referred to each other. The above description of the disclosed embodiments enables professionals and technicians in this field to implement or use the present invention.
