Description

Technical Field

[0001] The utility model relates to the technical field of metal connectors, and particularly relates to a square buckle structure for fields such as luggage, clothing, outdoor equipment, etc., especially a square buckle with enhanced connection stability and installation convenience. Background Art

[0002] As a common connector, the square buckle is widely used in fields such as luggage, clothing, outdoor equipment, etc. for connecting straps or ropes. Traditional square buckles are usually made of metal or plastic and include an outer ring buckle and an internal crossbar, and the connection function is realized through a simple mechanical structure. However, the square buckles in the prior art have the following technical problems:

[0003] First, the connection stability of the traditional square buckle is insufficient. After being subjected to a large pulling force or long-term use, the connection part is prone to looseness or even detachment. At present, although some square buckles improve the stability by increasing the number of connection points, the structure is complex, increasing the manufacturing cost and assembly difficulty.

[0004] Second, the anti-slip performance of the existing square buckles needs to be improved. Especially in a humid environment or during rapid movement, the strap is prone to slide within the buckle, resulting in an unreliable connection. At present, some square buckles propose to set anti-slip patterns inside the buckle, but the patterns are too shallow, the anti-slip effect is limited, and the patterns are prone to wear after long-term use.

[0005] Finally, the durability of the existing square buckles is insufficient. After long-term use, the connection part is prone to wear, and the connecting strap will curl or slip to one side, causing the wide and flat strap to become a long and thin strap, affecting the use experience and lifespan. Especially at the connection between the crossbar and the outer ring buckle, due to stress concentration, it is prone to breakage.

[0006] In view of the above problems, there is an urgent need for a new square buckle structure that can improve various performance indicators while maintaining a simple structure. Content of the Utility Model

[0007] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and provide a square buckle structure with stable connection, good anti-slip performance, convenient assembly and durability.

[0008] The technical scheme adopted by the utility model is as follows: a square buckle, comprising:

[0009] An outer ring buckle, the outer ring buckle is connected end to end to form a closed shape; a first strip-shaped protrusion is arranged on the surface of the outer ring buckle;

[0010] A plurality of crossbars, the crossbars are arranged inside the outer ring buckle; a second strip-shaped protrusion is arranged on the surface of the crossbars;

[0011] A crossbar portion, the crossbar portion being located within the space enclosed by the crossbar and the outer ring buckle, and a joint portion being provided on the surface of the crossbar portion;

[0012] A pressure cap, the surface of which is provided with snap feet, the snap feet cooperating with the connecting part to fix the pressure cap to the eye-shaped buckle.

[0013] Furthermore, the first strip-shaped protrusion and the second strip-shaped protrusion are arranged back to back.

[0014] Furthermore, the outer ring buckle is rectangular, and the first strip-shaped protrusion covers one side of the rectangular outer ring buckle.

[0015] Furthermore, the second strip-shaped protrusion is covered with a single crossbar.

[0016] Furthermore, the latching feet are located on both sides of the pressure cover, and two latching feet are provided on each side of the pressure cover.

[0017] Furthermore, the joint is provided with an inclination angle that tilts outward toward the crossbar.

[0018] Furthermore, the first strip-shaped protrusion includes several sub-protrusions, and the lengths of the several sub-protrusions are not consistent, presenting a layout that is longer on both sides and shorter in the middle.

[0019] Furthermore, the end of the sub-protrusion is provided with a buffer chamfer.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. Regarding connection stability, by setting a first strip-shaped protrusion and a second strip-shaped protrusion on the surface of the outer ring buckle and crossbar, the contact area and friction with the shoulder strap are increased, effectively preventing the shoulder strap from slipping inside the buckle. In particular, the first strip-shaped protrusion and the second strip-shaped protrusion are set back to back to form a mating structure, further enhancing the anti-slip effect.

[0022] 2. Regarding the cap's fixation, the innovative design of the buckle feet and the joint, with two buckle feet on each side of the cap, forms a four-point fixing structure, greatly improving the cap's fixing strength. The angled design of the joint allows the buckle feet to engage more tightly, preventing the shoulder strap from loosening and securing the shoulder strap so that it does not curl or shift during use.

[0023] 3. In terms of structural optimization, the first strip-shaped protrusion adopts a sub-protrusion layout with longer sides and a shorter middle section, which conforms to the force distribution law of the shoulder strap and reduces material usage while ensuring anti-slip effect. The cushioning chamfer at the end of the sub-protrusion prevents wear on the shoulder strap.

[0024] 4. In terms of ease of assembly, the optimized snap-fit ​​structure makes the cap installation simpler. It can be fixed simply by pressing, without the need for special tools, which facilitates production and maintenance.

[0025] Through the above-mentioned innovative design, this utility model significantly improves the connection stability, anti-slip performance and service life while maintaining the basic functions of the eye-shaped buckle. Moreover, the structure is simple, easy to produce and assemble, and has broad application prospects. Attached Figure Description

[0034] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

[0035] like Figure 1-4 As shown, this embodiment provides a tic-tac-toe buckle, including an outer ring buckle 1, a crossbar 2, a crossbar portion 3, and a pressure cap 4. The outer ring buckle 1 has a rectangular closed structure and is integrally formed from metal material. A first strip-shaped protrusion 11 is provided on the surface of the upper crossbar of the outer ring buckle 1. The first strip-shaped protrusion 11 is composed of multiple sub-protrusions 111, and the lengths of these sub-protrusions 111 are not consistent, such as... Figure 3 As shown, it presents a layout that is long on both sides and short in the middle. This layout is crescent-shaped, which can effectively reduce the stress when the strap comes into contact with this part, thus reducing wear. The end of each sub-protrusion 111 is processed with a buffer chamfer 112 to avoid scratching the strap.

[0036] like Figure 5-7As shown, two horizontal bars 2 are arranged parallel to each other inside the outer ring buckle 1, and each horizontal bar 2 has a second strip-shaped protrusion 21 on its surface. The second strip-shaped protrusion 21 covers the entire horizontal bar 2 and is arranged back-to-back with the first strip-shaped protrusion 11 on the outer ring buckle 1, forming a back-to-back structure. When the strap passes through, the first strip-shaped protrusion 11 and the second strip-shaped protrusion 21 work together to provide sufficient anti-slip friction.

[0037] The crossbar 3 is located within the space enclosed by the crossbar 2 and the outer ring buckle 1, and its surface is provided with a connecting part 31. The connecting part 31 is designed with an outward tilt angle to facilitate engagement with the snap-fit ​​foot 41 of the pressure cover 4.

[0038] The pressure cap 4 has two locking feet 41 on each side, for a total of four locking points. During installation, the pressure cap 4 is aligned with the crossbar 3 and pressed down. The locking feet 41 slide along the inclined surface of the joint 31, eventually locking the carrying strap into place for a secure fixation. The four locking points ensure the stability of the pressure cap 4 in all directions, preventing it from loosening. This means that even after prolonged use, the carrying strap will not curl or narrow, or shrink and slip to one side, thus preventing a decrease in wearing comfort.

[0039] This embodiment provides a method for assembling a clasp, such as... Figure 8 As shown:

[0040] Step 1: Insert the shoulder strap through one end of the outer buckle 1, through the channel formed by the two crossbars 2, and around the first strip protrusion 11 and the second strip protrusion 21;

[0041] Step 2: Adjust the strap length to a suitable position. The first strip protrusion 11 and the second strip protrusion 21 will have an anti-slip effect to prevent the strap from slipping.

[0042] Step 3: Align the pressure cap 4 with the crossbar 3 and press gently. The latch 41 will slide along the inclined surface of the joint 31 and snap into place.

[0043] Step 4: Check that all four clips 41 are fully engaged to ensure that the cover 4 is securely fixed.

[0044] To remove the strap, simply press the release buttons on both sides of the cover 4 with your fingers at the same time. The cover 4 can then be easily removed to adjust or replace the strap.

[0045] Through the specific structure described above, this utility model achieves several performance improvements for the eye-shaped buckle:

[0046] 1. Anti-slip tests show that, under the same tensile force, the anti-slip performance of the new type of buckle is improved by about 60% compared with the traditional structure;

[0047] 2. The cap fixing strength test shows that the four-point snap-fit ​​design increases the cap's pull-out resistance by about 80%;

[0048] 3. Durability tests have shown that the optimized structure extends the product's lifespan by approximately 50%.

[0049] 4. Assembly time tests show that the assembly efficiency of this invention is about 30% higher than that of the traditional structure.

[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
