Description

Technical Field

[0001] This utility model relates to the field of fasteners, and more specifically, to a safety buckle suitable for side-opening types. Background Technology

[0002] Side-opening buckles are a common type of fastener, widely used in many products due to their ease of engagement and disengagement. However, precisely because of this convenient opening method, they can accidentally disengage when not needed. Therefore, in products with high security requirements, it's necessary to utilize their ease of engagement while preventing accidental disengagement. This necessitates the development of new products to overcome these drawbacks. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the existing technology and provide a locking side-opening buckle that can be quickly fastened but requires an unlocking operation to unfasten.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] This utility model provides a locking side-opening buckle, including a first buckle and a second buckle. The first buckle has a first webbing buckle at one end and a fastening cavity at the other end; the fastening cavity has symmetrical side buckle grooves on both sides, a reverse buckle at the rear of the side buckle grooves, a locking groove and a button groove at the upper part of the fastening cavity, and a guide post on the center line of the bottom wall of the fastening cavity; the second buckle has a second webbing buckle at one end, symmetrical side buckles on both sides at the other end, a center buckle at the front end, and a locking buckle at the rear end; the first and second webbing buckles are respectively connected to the webbing; the side buckles have an elastic arm at the rear and a side buckle tongue at the front, with a reverse buckle groove at the rear end of the side buckle tongue; the center buckle has a flared opening at the front end, and a guide groove at the rear end of the flared opening; the locking buckle has a locking protrusion and an unlocking button; when fastened, the center buckle... The flared opening guides the guide post towards the center within a wide angle range. Subsequently, the guide post, in conjunction with the guide groove, guides the side buckle, center buckle, and locking buckle into the fastening cavity. Under the elastic tension of the elastic arm, the side buckle tongue engages in the side buckle groove, and the reverse buckle engages in the reverse buckle groove. Under the elastic tension of the locking buckle, the locking protrusion engages in the locking groove, locking the first and second buckle bodies into the fastening state. The unlock button protrudes from the button groove for pressing during unlocking. In the locked state, pressing the side buckle inward during the normal unlocking operation will not cause the first and second buckle bodies to separate. Pressing the unlock button while pressing the side buckle causes the reverse buckle to disengage from the reverse buckle groove, and the locking protrusion also disengages from the locking groove, allowing the second buckle body to separate from the first buckle body.

[0006] This utility model has the following beneficial effects: pressing the unlock button while pressing the side buckle causes the buckle to disengage from the buckle groove and the locking protrusion to disengage from the locking groove, thus unlocking the buckle and preventing accidental opening, thereby enhancing the safety of the buckle.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1-4As shown: This utility model provides a locking side-opening buckle, including a first buckle 1 and a second buckle 2. A first webbing buckle 11 is provided at one end of the first buckle 1, and a fastening cavity 12 is provided at the other end. Side buckle grooves 121 are symmetrically provided on both sides of the fastening cavity 12, and a reverse buckle 1211 is provided at the rear of the side buckle grooves 121. A locking groove 122 and a button groove 123 are provided on the upper part of the fastening cavity 12, and a guide post 124 is provided on the center line of the bottom wall of the fastening cavity 12. A second webbing buckle 21 is provided at one end of the second buckle 2, and side buckles 22 are symmetrically provided on both sides of the other end of the second buckle 2, with a center buckle at the front end of the middle section. 23. A locking buckle 24 is provided at the rear end of the middle section; the first webbing buckle 11 and the second webbing buckle 21 are respectively connected to the webbing; the side buckle 22 has an elastic arm 223 at the rear and a side buckle tongue 221 at the front, and a buckle groove 222 at the rear end of the side buckle tongue 221; the center buckle 23 has a flared opening 231 at the front end, and a guide groove 232 at the rear end of the flared opening 231; the locking buckle 24 has a locking protrusion 241 and an unlocking button 242; when fastened, the center buckle 23... The front flared opening 231 guides the guide post 124 towards the center within a wide angle range. Subsequently, the guide post 124 cooperates with the guide groove 232 to guide the side buckle 22, center buckle 23, and locking buckle 24 into the fastening cavity 12. Under the elastic tension of the elastic arm 223, the side buckle tongue 221 engages in the side buckle groove 121, and the reverse buckle 1211 engages in the reverse buckle groove 222. Under the elastic tension of the locking buckle 24, the locking protrusion 241 engages in the locking groove 122 to lock. When the first buckle 1 and the second buckle 2 are engaged, the unlock button 242 protrudes from the button groove 123 for pressing during unlocking. In the locked state, pressing the side buckle 22 inward during the normal unlocking operation will not cause the first buckle 1 and the second buckle 2 to separate. Pressing the unlock button 242 at the same time as pressing the side buckle 22 will cause the inverted buckle 1211 to disengage from the inverted buckle groove 222, and at the same time, the locking protrusion 241 will also disengage from the locking groove 122, so that the second buckle 2 can be separated from the first buckle 1.

[0016] The present invention has the following beneficial effects: when the side buckle 22 is pressed and the unlock button 242 is pressed at the same time, the buckle 1211 is disengaged from the buckle groove 222 and the locking protrusion 241 is also disengaged from the locking groove 122, so that the buckle can be released, preventing accidental opening and enhancing the safety of the buckle.

[0017] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, and all such modifications fall within the scope of the claims of the present utility model and should be protected by patent law.
