Description

Technical Field

[0001] This utility model relates to the field of bag technology, and in particular to a buckle structure and a backpack. Background Technology

[0002] In modern society, people need various types of buckles in their daily lives, such as those used on suspenders, packing straps, bags, and pet leashes, to quickly fasten and unfasten items. To meet these needs, a wide variety of buckles are available on the market, each with its own design philosophy, striving to meet the requirements of different users.

[0003] Fasteners typically consist of a male and a female fastener. However, existing male fasteners have solid pins that are not very flexible, requiring considerable force to press the pins on both sides to separate the male fastener from the female fastener. Furthermore, existing male and female fasteners lack a guiding structure during insertion, which can easily cause the male fastener to deviate during insertion, hindering the smooth connection between the male and female fasteners. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a snap-fit ​​structure.

[0005] In a first aspect, this application provides a snap-fit ​​structure, including:

[0006] The female buckle has an internally defined storage cavity. Both sides of the female buckle have arc-shaped openings that communicate with the storage cavity. The inner wall of the female buckle has a slide along its length. The front end of the female buckle has an extension that communicates with the storage cavity.

[0007] The female buckle has two symmetrical spring arms at one end extending toward the female buckle;

[0008] The sub-buckle includes a fastened state and an unfastened state. When switching from the unfastened state to the fastened state, the spring arm extends from the insertion port and slides along the slide rail into the storage cavity, so that the spring arm extends from the arc-shaped opening. When switching from the fastened state to the unfastened state, the spring arm retracts into the storage cavity and is pulled out of the storage cavity.

[0009] In one possible implementation, the end of the female buckle extending toward the female buckle is provided with a guide bar, the guide bar is located between the two elastic arms, and the inner top surface and inner bottom surface of the female buckle are provided with guide grooves along their length.

[0010] When switching from the unfastened state to the fastened state, the guide bar slides into the storage cavity along the guide groove.

[0011] In one possible implementation, both the upper and lower surfaces of the guide bar are provided with raised guide portions, which are adapted to the guide groove.

[0012] In one possible implementation, the rear end of the female buckle is connected along its width direction to a first crossbar for securing to the shoulder strap, and the rear end of the elastic arm is connected along its width direction to a second crossbar for securing to the shoulder strap.

[0013] In one possible implementation, the surfaces of the first and second horizontal bars are provided with anti-slip textures.

[0014] In one possible implementation, a fluorescent component is also included, comprising a transparent column and a fluorescent powder, the fluorescent powder being filled in the column, and a receiving cavity being formed on the upper and / or lower surface of the female buckle, the column being embedded in the receiving cavity, the female buckle being made of a transparent material.

[0015] In one possible implementation, a first magnetic block is fixed to the bottom of the accommodating cavity, and a second magnetic block adapted to the first magnetic block is provided at the bottom of the column.

[0016] In one possible implementation, the front end of the spring arm is provided with an abutment block; when the spring arm extends from the protrusion, the abutment block abuts against the outer wall of the female buckle.

[0017] Secondly, this application also provides a backpack, including the buckle structure described in the above embodiments.

[0018] The technical solutions provided in this application have the following advantages compared with the prior art:

[0019] By defining a storage cavity inside the female buckle and opening arc-shaped openings on both sides of the female buckle that communicate with the storage cavity, and symmetrically setting two spring arms at the end of the male buckle extending towards the female buckle, when the male buckle needs to be inserted into the female buckle, the two spring arms are squeezed inward so that the distance between the two spring arms is less than the width of the storage cavity, allowing the spring arms to slide into the storage cavity along the slide rails. When it reaches the position corresponding to the arc-shaped opening, the front end of the spring arm expands outward due to its own elastic force and extends out of the arc-shaped opening to abut against the outside of the female buckle, thus achieving the engagement of the male buckle and the female buckle. When it is necessary to remove the male buckle from the female buckle, simply squeeze the spring arm extending from the arc-shaped opening and pull the male buckle outward to quickly pull the male buckle out of the female buckle. The structure is simple and can quickly achieve the engagement and disengagement of the male buckle and the female buckle. At the same time, the slide rails on both sides of the female buckle guide the spring arms to slide more smoothly into the storage cavity, avoiding the problem of the male buckle easily deviating during the insertion process.

[0030] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0031] Please refer to Figures 1 to 3 This application provides a snap fastener structure, including a female snap fastener 10 and a female snap fastener 20. The female snap fastener 10 has an internally defined receiving cavity 10a. Both sides of the female snap fastener 10 have arc-shaped openings 10b communicating with the receiving cavity 10a. The inner wall of the female snap fastener 10 has a slide rail 10c along its length direction. The front end of the female snap fastener 10 has an insertion point communicating with the receiving cavity 10a. The female snap fastener 20 has two symmetrically arranged spring arms 70 at one end extending towards the female snap fastener 10. The female snap fastener 20 has a fastened state and an unfastened state. When switching from the unfastened state to the fastened state, the spring arms 70 extend from the insertion point and slide along the slide rail 10c into the receiving cavity 10a, so that the spring arms 70 extend out from the arc-shaped openings 10b. When switching from the fastened state to the unfastened state, the spring arms 70 retract into the receiving cavity 10a and are pulled out from the receiving cavity 10a.

[0032] For example, the spring arm 70 can be made of an elastic material so that the spring arm 70 has a certain elasticity, so that after being inserted into the receiving cavity 10a, it can extend out from the arc-shaped opening 10b due to its own rebound force, so as to realize the fastening of the female buckle 20 and the female buckle 10.

[0033] Based on the aforementioned technical features, the snap-fit ​​structure defines a receiving cavity 10a within the female snap 10, and provides arc-shaped openings 10b on both sides of the female snap 10 that communicate with the receiving cavity 10a. Simultaneously, two spring arms 70 are symmetrically arranged at the end of the male snap 20 extending towards the female snap 10. When the male snap 20 needs to be inserted into the female snap 10, the two spring arms 70 are pressed inwards, making the distance between the two spring arms 70 less than the width of the receiving cavity 10a. This allows the spring arms 70 to slide along the slide rail 10c into the receiving cavity 10a. When inserted into the position corresponding to the arc-shaped opening 10b, the front end of the spring arm 70, due to its own elastic force, moves towards... The outer expansion extends from the arc-shaped opening 10b and abuts against the outer side of the female buckle 10, thereby achieving the engagement of the female buckle 20 and the female buckle 10. When it is necessary to remove the female buckle 20 from the female buckle 10, simply squeeze the spring arm 70 extending from the arc-shaped opening 10b and pull the female buckle 20 outward to quickly pull the female buckle 20 out of the female buckle 10. The structure is simple and can quickly achieve the engagement and disengagement of the female buckle 20 and the female buckle 10. At the same time, slides 10c are provided on both sides of the female buckle 10 to guide the spring arm 70 to slide more smoothly into the storage cavity 10a, avoiding the problem of the female buckle 20 easily deviating during the insertion process.

[0034] In one possible implementation, the end of the female buckle 20 extending towards the female buckle 10 is provided with a guide bar 80, which is located between the two spring arms 70. The inner top and bottom surfaces of the female buckle 10 are both provided with guide grooves 10d along their length. When switching from the unfastened state to the fastened state, the guide bar 80 slides along the guide grooves 10d into the receiving cavity 10a. Thus, when the female buckle 20 is inserted into or pulled out of the female buckle 10, the guide bar 80 on the female buckle 20 can slide along the guide grooves 10d of the female buckle 10, thereby ensuring that the female buckle 20 can be inserted into or pulled out of the female buckle 10 more smoothly.

[0035] In one possible implementation, both the upper and lower surfaces of the guide bar 80 are provided with raised guide portions, which are adapted to the guide groove 10d.

[0036] In one possible implementation, a first crossbar 40 for securing to the shoulder strap is connected to the rear end of the female buckle 10 along its width direction, and a second crossbar 50 for securing to the shoulder strap is connected to the rear end of the elastic arm 70 along its width direction. Thus, by securing the first crossbar 40 to the rear end of the female buckle 10 and the second crossbar 50 to the rear end of the female buckle 20, the shoulder strap can be detachably connected to both the female buckle 10 and the female buckle 20, facilitating subsequent disassembly and replacement of either the female buckle 20 or the female buckle 10.

[0037] In one possible implementation, the surfaces of the first horizontal bar 40 and the second horizontal bar 50 are provided with anti-slip texture.

[0038] In one possible implementation, a fluorescent component is also included. This component comprises a transparent column 60 and phosphor. The phosphor is filled within the column 60. A receiving cavity is formed on the upper and / or lower surface of the female buckle 10, and the column 60 is embedded within this cavity. The female buckle 10 is made of a transparent material. Thus, by filling the column 60 with phosphor and then embedding it within the receiving cavity, the transparent material of the female buckle 10 allows the light emitted by the phosphor to pass through in the dark, accurately displaying its location and effectively preventing safety accidents, thus ensuring good safety.

[0039] In one possible implementation, a first magnetic block is fixed to the bottom of the accommodating cavity, and a second magnetic block adapted to the first magnetic block is provided at the bottom of the column 60. This allows the column 60 to be more securely mounted on the female buckle 10, preventing it from falling off during use.

[0040] In one possible implementation, the front end of the spring arm 70 is provided with an abutment block 30; when the spring arm 70 extends from the protrusion, the abutment block 30 abuts against the outer wall of the female buckle 10.

[0041] This disclosure also provides a backpack, including the buckle structure described in the above embodiments.

[0042] The backpack according to the embodiments of this disclosure adopts the above-described buckle structure, and its technical effects are the same as those of the buckle structure described above, so they will not be repeated here.

[0043] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
