Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a drawstring bag processing device, in particular to a drawstring bag hook needle. Background Art
[0002] Drawstring bags are a common packaging container, and their main feature is that the bag opening can be tightened by shrinking or tying to prevent leakage of items in the bag or entry of external objects. In the production and use of drawstring bags, a hook is often needed to pass through the channel outside the bag opening for accommodating the laces, and hook the laces or ropes into the channel to complete the processing of the drawstring bag. Traditional hooks are mostly simple wire hooks. Although these hooks can complete basic piercing functions, they have some inconveniences and limitations in use. Traditional hooks are mainly made of wire or similar materials, and their design is relatively simple. They are usually formed into a hook-shaped structure by manually bending the wire. This design has the following problems:
[0003] The tip and edge of the wire hook may scratch or damage the bag material of the drawstring bag, especially for soft or weak bag materials, and it is not convenient to hook the tie or rope into the channel.
[0004] The length of traditional hooks is fixed and cannot be flexibly adjusted. Therefore, different sizes of drawstring bags require a variety of hooks of different lengths, which increases production costs and the complexity of inventory management. Utility Model Content
[0005] 1. Technical issues
[0006] The utility model provides a drawstring bag hook needle, aiming to solve the problems that the hook head of a traditional hook needle is easy to hook the bag body to cause obstruction and the fixed length cannot be adjusted.
[0007] (II) Technical content
[0008] In order to solve the above technical problems, the technical solution of the utility model is: a drawstring bag hook needle, including a hook needle body, a cavity is provided at the bottom of the hook needle body, an extension rod is provided inside the cavity for plug-in connection, a spring buckle assembly is provided on the side of one end of the extension rod extending into the cavity, a plurality of circular clip holes are provided on the side of the hook needle body corresponding to the spring buckle assembly, the front and rear sides of the upper end of the hook needle body are provided with inclined surfaces inclined toward the center, and the upper end of the hook needle body is provided with an upwardly inclined groove.
[0009] Furthermore, the spring buckle assembly includes an insertion cavity arranged on the side of the extension rod, a limiting steel ball is provided in the insertion cavity for insertion connection, a limiting plate is fixed to one end of the limiting steel ball extending into the insertion cavity, a spring is provided between the limiting plate and the bottom surface of the insertion cavity, and the other end of the limiting steel ball is matched and engaged with the circular clamping hole.
[0010] Furthermore, a rounded corner is arranged at the edge of the lower end of the hook body.
[0011] Furthermore, the hook body and the extension rod are both long strip-shaped plate structures.
[0012] (III) Technical Effect
[0013] Compared with the prior art, the utility model has the following advantages: a cavity is provided at the bottom of the hook needle body, and an extension rod with adjustable length is inserted and connected inside, so that the length of the hook needle can be adjusted according to needs, and a circular clamping hole and a spring clamping assembly are used to limit the length, which is stable, reliable and convenient to adjust. The upper end of the hook needle is designed with an inclined surface and a groove, and the whole adopts a long strip plate structure. The inclined surface design is conducive to passing the hook needle body through the lacing channel, and when pulling back the lacing, it will not hook the bag body, which greatly improves the processing efficiency of the drawstring bag.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside", "center", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction structure and operation. Therefore, they should not be understood as limitations on the present invention.
[0020] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "provided with", "installed", "connected", "connected" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0022] Combined with Figure 1 To Attachment Figure 4 A drawstring bag hook needle comprises a hook needle body 1, a cavity 2 is provided at the bottom of the hook needle body 1, an extension rod 3 is provided inside the cavity 2 for insertion and connection, a spring buckle assembly 4 is provided on the side of one end of the extension rod 3 extending into the cavity 2, a plurality of circular clamping holes 5 are provided on the side of the hook needle body 1 corresponding to the spring buckle assembly 4, the front and rear sides of the upper end of the hook needle body 1 are provided with inclined surfaces 6 inclined toward the center, and a groove 7 obliquely upward is provided on the side of the upper end of the hook needle body 1.
[0023] The spring buckle assembly 4 includes an insertion cavity 8 arranged on the side of the extension rod 3, and a limiting steel ball 9 is inserted and connected in the insertion cavity 8. A limiting plate 10 is fixed to one end of the limiting steel ball 9 extending into the insertion cavity 8. A spring 11 is provided between the limiting plate 10 and the bottom surface of the insertion cavity 8, and the other end of the limiting steel ball 9 is matched and engaged with the circular clamping hole 5.
[0024] A rounded corner 12 is arranged at the lower edge of the hook body 1, and the hook body 1 and the extension rod 3 are both long strip plate-like structures.
[0025] The rounded corner design can effectively reduce the friction and scratching when the hook needle contacts the bag material. The traditional sharp corner design easily causes damage or wear to the bag material, especially for soft or weak bag materials. The rounded corner can reduce this damage.
[0026] The specific working principle of the utility model is as follows: before use, the drawstring bag body and the lace are prepared, a channel for inserting the lace is sewn at the opening of the upper end of the drawstring bag body, and the extension length of the extension rod 3 is adjusted according to the size of the drawstring bag. Specifically, the limiting steel ball 9 is pressed, and the extension rod 3 is pulled outward or pushed inward at the same time until the limiting steel ball 9 is stuck in the appropriate circular clamping hole 5. The upper end of the hook needle body 1 is passed through the lace channel by holding the extension rod, and then the lace is hung in the groove 7 at the end that has passed through, and then the hook needle body is pulled back, and the hook needle body passes through the channel with the lace, so that the lace is smoothly inserted into the channel to complete the processing of the drawstring bag.
[0027] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
