[0033] The following is an explanation of the embodiments disclosed in the present application through specific embodiments. Those skilled in the art can understand the advantages and effects of the present application from the contents disclosed in this specification. The present application can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the concept of the present application. In addition, the drawings of the present application are only simple schematic illustrations and are not depicted according to actual sizes. It is stated in advance. The following embodiments will further explain the relevant technical contents of the present application in detail, but the disclosed contents are not intended to limit the scope of protection of the present application.

[0034] It should be understood that, although the terms "first", "second", etc. may be used herein to describe various components, these components should not be limited by these terms. These terms are mainly used to distinguish one component from another component. In addition, the term "or" used herein may include any one or more combinations of the associated listed items depending on the actual situation.

[0035] Please refer to Figures 1 to 4 The present application provides a safety release buckle, comprising a base 1 and a buckle 2 .

[0036] The base 1 includes a base 10, two slide rails 11, and optionally at least one cut. Optionally, the base 1 can be made of a material with good strength and elasticity, such as engineering plastic materials such as POM and nylon, or a composite structure composed of spring steel sheets or metal sheets and plastics.

[0037] An opening 101 is formed in the center of the base 10 .

[0038] The two slide rails 11 are spaced apart from each other on the base 10. The two slide rails 11 and the base 10 form a slide slot 15, and the two ends of the slide slot 15 define a first end 151 and a second end 152, and the direction from the first end 151 to the second end 152 is defined as a disengagement direction D.

[0039] Each slide rail 11 has a side wall 111, a limiting wall 112, a clamping portion 113, an entry section 114, a limiting portion 115, and a disengagement section 116. The side wall 111 is disposed on the base 10. The limiting wall 112 is connected to the side wall 111 and extends toward the other slide rail 11. The clamping portion 113 is formed on the limiting wall 112. The clamping portion 113 gradually extends obliquely toward the slide groove 15 along the disengagement direction D. In other words, the two clamping portions 113 extend obliquely toward each other along the disengagement direction D. The entry section 114 is formed on the limiting wall 112 and extends from the first end 151 to the clamping portion 113. The spacing between the entry sections 114 of the two slide rails 11 gradually narrows from the first end 151 to the clamping portion 113. The limiting portion 115 is formed on the limiting wall 112, has a concave shape, and is connected between the clamping portion 113 and the entry section 114. The disengagement section 116 is formed on the limiting wall 112 and extends from the engaging portion 113 to the second end 152. The distance between the disengagement sections 116 of the two slide rails 11 gradually widens from the engaging portion 113 to the second end 152.

[0040] In this embodiment, the slits of the base 1 include a first slit 12 , two second slits 13 , and two third slits 14 .

[0041] The first slit 12 passes through the center line of the base 10 and extends from the opening 101 to the second end 152. The first slit 12 can provide a space for the base 10 to bend or deform.

[0042] The two second slits 13 are located on both sides of the first slit 12 and penetrate the base 10. The two second slits 13 extend from the second end 152 to the first end 151 and are located between the two slide rails 11. Thus, when the separation sections 116 of the two slide rails 11 are subjected to a force to be stretched apart, the second slits 13 can provide a space for the base 10 to bend or deform, and the two slide rails 11 will move away from each other, thereby widening the distance between the separation sections 116 of the two slide rails 11.

[0043] The two third slits 14 are respectively perpendicular to the disengagement direction D and penetrate the side walls 111 of the two slide rails 11, and one end of each third slit 14 extends to the base 10, and the other end extends to the limiting wall 112. The third slit 14 is between the first end 151 and the second end 152. Thus, when the disengagement sections 116 of the two slide rails 11 are subjected to a force to be stretched apart, the third slits 14 can provide space for the side walls 111 of the two slide rails 11 to bend or deform, thereby widening the distance between the disengagement sections 116 of the two slide rails 11.

[0044] In other embodiments, the slits of the base 1 are not limited to the first slit 12, the second slit 13, and the third slit 14. Alternatively, the base 1 may not have slits, but instead bends elastically by relying on the material of the base 1 itself.

[0045] Please refer to Figure 1 , Figure 3 , Figure 5 , Figure 6 The fastener 2 can be detachably mounted on the base 1. In this embodiment, the first end 151 is a mounting end, and the fastener 2 enters the slide groove 15 from the first end 151, and the second end 152 is a disengagement end, and the fastener 2 disengages from the slide groove 15 from the second end 152. In other embodiments, the first end 151 may not be a mounting end, and the fastener 2 may enter the slide groove 15 from the second end 152 or other positions.

[0046] When the fastener 2 is subjected to a force greater than a default value and in the disengagement direction D, the fastener 2 can be disengaged from the slide slot 15 from the second end. The fastener 2 is used to connect an external device. The fastener 2 includes a main body 20, a connecting portion 21, a buckle protrusion 22, an elastic protrusion 23, and an operating protrusion 24. Optionally, the fastener 2 can be made of elastic engineering plastic materials such as POM, nylon, etc., and can be made by plastic injection.

[0047] The main body 20 can be disposed between the side walls 111 of the two slide rails 11, and is limited by the limiting walls 112 of the two slide rails 11. Specifically, the height of the main body 20 is less than the distance between the limiting walls 112 and the base 10, and the width of the main body 20 is greater than the distance between the limiting walls 112 of the two slide rails 11, and less than the distance between the two side walls 111. Thus, when the main body 20 is disposed in the slide groove 15, it will be limited in the slide groove 15 by the limiting walls 112 of the two slide rails 11, so that the fastener 2 can only slide along the slide groove 15, and will not detach from the base 1 in a direction perpendicular to the detachment direction D. In this embodiment, as Figure 6 As shown, the main body 20 is a hollow shell, and includes an upper surface 201, a lower surface 202, an upper shell plate 203, and a lower shell plate 204. One end (around the lower half) of the upper shell plate 203 is connected to one end (around the lower half) of the lower shell plate 204, and is slightly U-shaped when viewed from the side. The upper surface 201 is located on the upper shell plate 203, and the lower surface 202 is located on the lower shell plate 204. A hole 205 is formed in the center of the lower shell plate 204.

[0048] The connecting portion 21 is disposed on the main body 20 for connecting to an external device. The connecting portion 21 may be a rope loop, such as Figure 1 and Figure 2 As shown, or a slotted hole for mounting a buckle strap, such as Fig.13 When the fastener 2 is installed in the slide slot 15, the connecting portion 21 faces the second end 152. In other words, when the safety release buckle is used, the fastener 2 receives a force in the release direction D when the external device is subjected to gravity or external pulling force.

[0049] The buckle protrusion 22 is disposed on the upper surface 201 of the main body 20 and can slide between the limiting walls 112 of the two slide rails 11. In this embodiment, the buckle protrusion 22 has an upper side surface 221, two abutting surfaces 222, and a positioning member 223.

[0050] The upper side surface 221 is an arc surface. Two abutting surfaces 222 are connected to the two ends of the upper side surface 221 and are inclined toward each other. The positioning member 223 is connected and protrudes between the two abutting surfaces 222. The width of the positioning member 223 is narrower than the distance between the ends of the engaging portions 113 of the two slide rails 11.

[0051] Please refer to Figure 6 , Figure 7 , Fig. 9 , Fig.10 The elastic protrusion 23 is disposed in the hole 205 of the lower shell plate 204 . The elastic protrusion 23 includes an elastic member 231 , a protruding portion 232 , a first stop portion 233 , a guiding surface 234 , and a second stop portion 235 .

[0052] The elastic member 231 is connected to the main body 20. The protrusion 232 is connected to the elastic member 231 and protrudes from the lower surface 202, and can be subjected to a restoring force exerted by the elastic member 231 to move away from the main body 20. In this embodiment, the elastic member 231 is a spring, connected to the hole wall around the hole 205, and extends toward the connecting portion 21. The elastic protrusion 23 can be pressed into the hollow main body 20, so that the protrusion 232 does not protrude from the lower surface 202. In other embodiments, the elastic member 231 can be a spring or other elastic structure, or the elastic protrusion 23 itself is a protrusion made of an elastic material.

[0053] like Figure 6 As shown, the first stopper 233 is disposed on one side of the protrusion 232. The guide surface 234 is connected to the first stopper 233 and is farther away from the lower surface 202 than the first stopper 233. Figure 8 As shown, when the fastener 2 enters the slide slot 15 and reaches the engaging portion 113, the elastic protrusion 23 can be engaged with the opening 101 of the base 10. Fig. 9 At the same time, the first stop portion 233 of the elastic protrusion 23 faces the second end 152 and abuts against the hole wall around the opening 101 .

[0054] See also Fig. 9 The first stopper 233 and the hole wall around the opening 101 of the base 10 can be parallel or inclined. The guide surface 234 is more inclined to the hole wall around the opening 101 than the first stopper 233 .

[0055] See also Figures 9 to 12, when the fastener 2 is subjected to a force greater than the default value and in the disengagement direction D, for example, the connecting portion 21 is pulled unexpectedly. The hole wall around the opening 101 and the first stop portion 233 of the elastic protrusion 23 push against each other, generating a component force in the direction toward the main body 20, so that the elastic protrusion 23 is compressed toward the main body 20. The hole wall around the opening 101 contacts the guide surface 234 of the elastic protrusion 23, and the elastic protrusion 23 can be further compressed toward the main body 20, and the guide surface 234 leaves the hole wall around the opening 101, allowing the fastener 2 to disengage from the slide groove 15. When the hole wall around the opening 101 contacts the guide surface 234, the fastener 2 subjected to the force (which does not need to be greater than the default value) can disengage from the slide groove 15.

[0056] The default value of the force of the above-mentioned fastener 2 to disengage from the slide groove 15 can be designed and adjusted according to the height, area, and relative contact angle between the first stopper 233 and the hole wall around the opening 101. In this embodiment, the default value can be set to 3 to 10 kilograms (kgf), but is not limited thereto. In this way, the fastener 2 can change the parameters such as the height, area, and relative contact angle of the contact portion between the first stopper 233 and the hole wall around the opening 101 according to factors such as the weight of the external device and the working environment, so that the default value of the force of the first stopper 233 to disengage from the slide groove 15 is changed. Furthermore, the manufacturer can pre-design multiple fasteners 2 with different default values ​​of the disengagement force, so that the fastener 2 becomes a replaceable part on the base 1.

[0057] In this embodiment, the operator can manually remove the fastener 2 from the base 1. Figure 6 As shown, the second stopper 235 of the elastic protrusion 23 is disposed on the protrusion 232 and protrudes from the lower surface 202. The second stopper 235 is located on one side of the elastic protrusion 23 and is opposite to the first stopper 233. When the elastic protrusion 23 is engaged with the opening 101 of the base 10 (see Figure 2 ), the second stopper 235 faces the first end 151. The second stopper 235 can prevent the fastener 2 from disengaging from the slide slot 15 in the opposite direction to the disengagement direction D. When the operator wants to actively remove the fastener 2 from the base 1, the operator can press the elastic protrusion 23 with a finger so that the second stopper 235 disengages from the opening 101, and the fastener 2 can be taken out from the direction of the first end of the base 1. In this embodiment, the protrusion 232 gradually protrudes from the second stopper 235 toward the first stopper 233 to form an inclined structure. Through the above design, the snap-in depth of the second stopper 235 and the opening 101 is less than the snap-in depth of the first stopper 233 and the opening 101, thereby reducing the depth of the operator pressing the elastic snap 23 when withdrawing the fastener 2.

[0058] like Figure 5 and Figure 6As shown, the operating protrusion 24 is disposed on the buckle protrusion 22. In this embodiment, the operating protrusion 24 is disposed on the positioning member 223, but is not limited thereto. When the fastener 2 is installed in the slide groove 15, the operating protrusion 24 protrudes between the limiting walls 112 of the two slide rails 11. Thus, the user can push against the operating protrusion 24 to drive the fastener 2 to move in the slide groove 15.

[0059] Please refer to Figure 4 and Figure 8 When the fastener 2 is installed in the slide slot 15 along the disengagement direction D, the maximum width D22 of the buckle protrusion 22 perpendicular to the disengagement direction D is defined as the maximum width of the buckle protrusion 22. In this embodiment, the maximum width D22 of the buckle protrusion 22 is the distance between the two ends of the upper side surface 221.

[0060] The maximum width D22 of the buckle protrusion 22 is slightly smaller than the distance D1 between the entry section 114 of the two slide rails 11 and the first end 151. The maximum width D22 of the buckle protrusion 22 is close to the distance D2 at the junction of the entry section 114 and the limiting portion 115 of the two slide rails 11. The maximum width D22 of the buckle protrusion 22 is greater than the distance D3 between the ends of the engaging portion 113 of the two slide rails 11, that is, the distance D3 at the junction of the disengagement section 116 and the engaging portion 113 of the two slide rails 11.

[0061] like Figure 4 As shown, when the fastener 2 enters the slide groove 15 from the first end 151, the elastic protrusion 23 is compressed by the base 10 toward the inside of the main body 20 (see Figure 3 ), the snap-on protrusion 22 can pass through the entry sections 114 of the two slide rails 11 without hindrance.

[0062] like Figure 8 , Fig. 9 As shown, the buckle protrusion 22 of this embodiment can provide stability for the safety release buckle in the buckled state. When the buckle protrusion 22 reaches the buckle portion 113 of the two slide rails 11, the limiting portion 115 of the two slide rails 11 partially abuts against the upper side surface 221 of the buckle protrusion 22, and the buckle portion 113 of the two slide rails 11 abuts against the two abutting surfaces 222 of the buckle protrusion 22. At this time, the positioning member 223 extends from the end of the buckle portion 113 of the two slide rails 11 to between the release sections 116 of the two slide rails 11. The elastic protrusion 23 can rebound and fit into the opening 101 of the base 10 (see FIG. 10 ). Figure 3 ). In this state, when the fastener 2 is subjected to a force opposite to the disengagement direction D, the limiting portions 115 of the two slide rails 11 will engage with the snap protrusions 22, so that the fastener 2 cannot leave the slide slot 15 in the opposite direction to the disengagement direction D. The two abutment surfaces 222 and the elastic protrusions 23 can improve the stability of the fastener 2 when it bears the weight or tension of the external device. The positioning member 223 can limit the rotation of the fastener 2 relative to the slide slot 15, reducing the impact of the shaking of the external device on the rotation of the fastener 2.

[0063] Please refer to Figures 9 to 12 The following example illustrates how the safety disengagement buckle of this embodiment improves the safety of the staff. When the fastener 2 is subjected to a force greater than the default value and in the disengagement direction D, the buckle protrusion 22 pushes against the two slide rails 11, causing the base 10 to bend along the first slit 12 and the second slit 13, and the side walls 111 of the two slide rails 11 along the third slit 14, whereby the two slide rails 11 gradually move away from each other until the distance between the ends of the engaging portions 113 of the two slide rails 11 is greater than the maximum width of the buckle protrusion 22. At the same time, the hole wall around the opening 101 of the base 10 and the first stop portion 233 of the elastic protrusion 23 push against each other, compressing the elastic protrusion 23 into the interior of the main body 20. The fastener 2 can then pass through the disengagement section 116 along the disengagement direction D and disengage from the slide groove 15 of the base 1 from the second end 152. During use, the staff's shoulder strap B (see Fig.11 ) is connected to an external connection hole 103 of the base 1, and the connection portion 21 of the fastener 2 is connected to an external device (such as a tablet computer). Under normal circumstances, the safety release buckle can stably support the external device. Once an emergency situation such as the external device being hooked and involved in the machine is encountered, the external force causes the fastener 2 to automatically separate from the base 1. In this way, the staff does not need to actively untie the restraints with the external device, and the safety release buckle can automatically separate the staff from the external device, thereby ensuring the life safety of the staff.
