[0039] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0040] In the description of the present invention, it should be understood that the terms "up", "down", "front", "back", "left" and "right" 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 positions or elements referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limitations of the present invention.

[0041] The utility model aims to provide a quick-release belt buckle, which can allow a user to quickly remove a belt in an emergency situation and improve the user's efficiency.

[0042] It should be noted that, in this embodiment, the direction X in the accompanying drawings is defined as the first direction, and the direction A is the direction in which the belt moves.

[0043] To achieve the above objectives, the present invention provides the following technical solutions:

[0044] See also Figures 1 to 7 , this embodiment provides a quick-release belt buckle, including: a buckle body 100, a male rod 200, a female rod 300 and an insertion pin 400; the buckle body 100 includes a first support rod 110 and a second support rod 120 connected at an angle; the male rod 200 is rotatably connected to the free end of the first support rod 110; the female rod 300 is rotatably connected to the free end of the second support rod 120; the insertion pin 400 is rotatably connected to the middle part of the second support rod 120; the free end of the male rod 200 can be clamped with the free end of the female rod 300, so that the buckle body 100, the male rod 200 and the female rod 300 form a closed loop, and the insertion pin 400 can fit with the male rod 200 in the clamped state.

[0045] Specifically, if Figure 1 and Figure 2As shown, the waist buckle body 100 is an integrated structure. At the middle position of the second support rod 120, a rotatable pin 400 is installed. The pin 400 rotates perpendicular to the second support rod 120 and is used to pass through the hole set on the belt 01; the male rod 200 and the female rod 300 are respectively rotatably connected to the two free ends of the waist buckle body 100, and the male rod 200 and the female rod 300 can be buckled together after rotating to a certain angle, so that the waist buckle body 100, the male rod 200 and the female rod 300 will form a closed quadrilateral ring; at this time, if the belt 01 is passed through the quadrilateral ring formed by the waist buckle body 100, and the pin 400 passes through the hole on the belt 01, the belt 01 will be stably connected to the waist buckle body 100 and will not fall off. Figure 6 shown.

[0046] In this embodiment, the material of the waist buckle body 100 is preferably metal, which can extend its service life. Of course, the waist buckle body 100 can also be formed by injection molding, which is not specifically limited herein.

[0047] When the waist buckle is in use and the belt 01 needs to be removed, the free ends of the male rod 200 and the female rod 300 are separated from the clamping state and the end rods, and then the male rod 200 and the female rod 300 are rotated outward. At this time, the free end of the pin 400 will be separated from the male rod 200 and in an unconstrained state. In this way, the user can directly pull the belt 01 to complete the removal of the belt 01. This setting greatly improves the speed of removing the belt 01. Figure 7 As shown, direction A is the direction of movement of the belt 01; when the belt 01 needs to be put on again, first pass the pin 400 through the hole on the belt 01, and then rotate the male rod 200 and the female rod 300 to engage the free ends of the two. At this time, the end of the pin 400 will fit into the male rod 200, so that the belt is not easily affected by external forces and falls off during use.

[0048] Preferably, the first support rod 110 and the second support rod 120 are vertically connected so that the waist buckle body 100 forms an L-shaped structure, a first U-shaped groove 111 is provided at the free end of the first support rod 110, one end of the male rod 200 is hinged in the first U-shaped groove 111 through a first pin shaft 112, a second U-shaped groove 121 is provided at the free end of the second support rod 120, and one end of the female rod 300 is hinged in the second U-shaped groove 121 through a second pin shaft 122.

[0049] In this embodiment, the first support rod 110 and the second support rod 120 are vertically connected to form an L-shaped structure for the waist buckle body 100. This structure facilitates the processing and manufacturing of the waist buckle body 100. Moreover, this arrangement can form a closed four-sided ring with the male rod 200 and the female rod 300. Of course, in other embodiments, the waist buckle body 100 can also be a rod of other shapes.

[0050] In addition, in this embodiment, in order to facilitate the connection between the male rod 200 and the female rod 300, U-shaped grooves are provided at both free ends of the waist buckle body 100. Specifically, the end of the first support rod 110 is a first U-shaped groove 111, and the end of the second support rod 120 is a second U-shaped groove 121, and a through hole is provided in the middle of the first U-shaped groove 111 and the second U-shaped groove 121. At the same time, a through hole is also provided at one end of the male rod 200 and the female rod 300. When installing the male rod 200 and the female rod 300, the ends of the two with through holes are respectively extended into the first U-shaped groove 111 and the second U-shaped groove 121, and the through holes are aligned, and then pins are passed through the through holes. Specifically, the first U-shaped groove 111 is passed through a first pin 112, and the second U-shaped groove 121 is passed through a second pin 122. Of course, other connection methods can also be selected for the male rod 200 and the female rod 300, which are not specifically limited in this article.

[0051] Preferably, a torsion spring 500 is sleeved on the outer circumference of the first pin shaft 112, a first protrusion 220 is provided at the connecting end of the male rod 200 and the first support rod 110, a second protrusion 1111 is provided in the first U-shaped groove 111, and the two ends of the torsion spring 500 respectively abut the first protrusion 220 and the second protrusion 1111, so that the male rod 200 has a tendency to rotate along the first direction.

[0052] Further, if Figure 3 and Figure 5 As shown, in this embodiment, in order to prevent the male rod 200 and the female rod 300 from loosening due to external force when they are in the clamped state, a torsion spring 500 is sleeved on the first pin 112, and the torsion spring 500 is located inside the first U-shaped groove 111. At the same time, a first protrusion 220 is provided at the connecting end of the male rod 200, and a second protrusion 1111 is provided at the bottom of the first U-shaped groove 111. The first protrusion 220 and the second protrusion 1111 respectively abut against one edge of the torsion spring 500. In this way, the male rod 200 has a tendency to rotate outward without any external force, that is, Figure 2 In the first direction; when the ends of the male rod 200 and the female rod 300 are connected, since the male rod 200 has a tendency to rotate outward, this will increase the pressure between the free ends of the male rod 200 and the female rod 300, making the connection between the two tighter, so that the belt is not easily affected by external forces and falls off during use.

[0053] Preferably, a limiting protrusion 1112 is further provided in the first U-shaped groove 111 , and the limiting protrusion 1112 is used to limit the rotation of the male rod 200 .

[0054] Furthermore, in order to prevent the first support rod 110 from rotating too much when rotating outward, a limiting protrusion 1112 is further provided in the first U-shaped groove 111, and the limiting protrusion 1112 and the second protrusion 1111 are connected to form a step-shaped protrusion as a whole. Figure 5 As shown, the thickness of the limiting protrusion 1112 can be adjusted according to actual conditions. In this embodiment, the setting of the limiting protrusion 1112 makes the maximum rotation angle of the male rod 200 only flush with the first support rod 110. Figure 4 and Figure 5 shown.

[0055] Preferably, the free end of the male rod 200 is provided with a snap-fit ​​protrusion 210 , and the free end of the female rod 300 is provided with a snap-fit ​​hole 310 , and the snap-fit ​​protrusion 210 can be inserted into the snap-fit ​​hole 310 and snap-fit ​​with the snap-fit ​​hole 310 under the action of the torsion spring 500 .

[0056] Furthermore, in this embodiment, the specific locking method of the male rod 200 and the female rod 300 is the cooperation of the protrusion and the locking hole. Specifically, a locking protrusion 210 is provided on the outer side of the free end of the male rod 200, and a locking hole 310 is provided at the free end of the female rod 300. When the male rod 200 and the female rod 300 need to be locked, just press the male rod 200 to rotate it away from the first direction, and at the same time rotate the female rod 300 so that the locking protrusion 210 provided at the end of the male rod 200 can be inserted into the locking hole 310, and due to the action of the torsion spring 500, the male rod 200 has a tendency to rotate outward, so that the outer peripheral surface of the male rod 200 will be tightly attached to the inner side surface of the rightmost end of the locking hole 310, and due to the presence of the locking protrusion 210, the male rod 200 and the female rod 300 are firmly locked together.

[0057] Preferably, the side of the male rod 200 facing away from the engaging protrusion 210 is configured as a smooth arc surface, so that the engaging protrusion 210 can be easily engaged with the engaging hole 310 .

[0058] In this embodiment, in order to facilitate the smooth insertion of the locking protrusion 210 into the locking hole 310 when pressing the male rod 200, the side of the male rod 200 facing away from the locking protrusion 210 is a smooth arc surface, that is, in this embodiment, the male rod 200 is configured as a whole to be slightly curved toward the first direction; such a configuration not only makes the locking of the male rod 200 and the female rod 300 smoother, but also, due to the curvature of the male rod 200, makes the locking of the male rod 200 and the female rod 300 less likely to be unlocked without the action of external force.

[0059] Preferably, an annular groove 123 is provided in the middle of the second support rod 120 , and the pin 400 is rotatably installed in the annular groove 123 .

[0060] In this embodiment, specifically Figure 2 and Figure 3 As shown, in order to allow the pin 400 to rotate stably on the first support rod 110 , an annular groove 123 is opened in the middle of the second support rod 120 , and the width of the annular groove 123 is just enough to install the pin 400 .

[0061] Preferably, a bending portion is provided at the end of the insertion pin 400 facing away from the annular groove 123 so that the insertion pin 400 can fit closely with the second support rod 120 .

[0062] Specific as Figure 3 and Figure 4 As shown, the free end of the pin 400 is provided with a downwardly bent portion. When the male rod 200 and the female rod 300 are in a clamped state, the bent portion of the pin 400 can just fit into the upper side of the male rod 200, thereby making the belt 01 more stable when worn.

[0063] Preferably, both ends of the first pin shaft 112 and the second pin shaft 122 are riveted to limit their axial movement.

[0064] In this embodiment, the first pin shaft 112 and the second pin shaft 122 are riveted to form protrusions at their ends, so that the two pin shafts can be stably installed in their respective positions; of course, through holes can also be opened at the ends of the first pin shaft 112 and the second pin shaft 122, and then pins can be inserted into the through holes to complete the installation of the two.

[0065] Preferably, the pin 400 is made of metal.

[0066] It can be understood that in this embodiment, the material of the pin 400 is preferably metal, which can maximize the service life of the waist buckle.

[0067] In summary, this document provides a quick-release belt buckle. The male rod 200 opens the buckle via the elastic force of a torsion spring 500. Once the male rod 200 springs open, the belt can be quickly removed by simply pulling the belt. The engaging protrusion 210 of the male rod 200 hooks onto the outer ring of the engaging hole 310 of the female rod 300. The elastic force of the torsion spring 500 and the blocking effect of the engaging protrusion 210 of the male rod 200 prevent the belt from being pulled off during use due to external forces. This provides both stability, preventing accidental opening due to external forces, and the convenience of quick belt removal, enhancing both safety and ease of removal for the user.
