Technical Field

[0001] The present invention relates to the technical field of safety equipment, and in particular to a safety buckle and a safety belt. Background Art

[0002] At present, most of the safety locks used in daily life are plug-in buckles that require a single button to be pressed from top to bottom to disengage the hook from the buckle. Such safety locks are often prone to getting stuck during use, or require a lot of force to press, and cannot be quickly unlocked; at the same time, they are easy to come loose when violently unlocked, and the buckle has poor stability and low safety. Moreover, the buckle of the safety lock cannot bear excessive pressure, which can easily lead to problems such as breakage and failure. Summary of the invention

[0003] The main purpose of the present invention is to provide a safety buckle and a safety belt to solve the problem of poor stability of the safety buckle in the prior art.

[0004] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, there is provided a safety lock, comprising two snap-fitting parts arranged to be snapped together or separated, at least one snap-fitting part comprising: a base; an operating member movably connected to the base, the operating member having an operating end and a locking end; a locking member, the locking member being arranged at the locking end, and when the operating member is actuated, the locking member is driven to move to lock or unlock the other snap-fitting part.

[0005] Furthermore, the base has a mounting cavity, the operating end of the operating member is exposed outside the mounting cavity, and at least a portion of the locking member can extend outside the mounting cavity to lock another buckling portion.

[0006] Furthermore, the locking member has a slide groove, and the locking end is located in the slide groove. When the operating member is actuated, the locking end squeezes the side wall of the slide groove to drive the locking member to move.

[0007] Furthermore, the locking member is movably arranged relative to the base body, and an angle is formed between the direction in which the locking end extends into the slide slot and the movement direction of the locking member.

[0008] Furthermore, the direction in which the locking end extends into the sliding slot is perpendicular to the movement direction of the locking member.

[0009] Further, the operating member is rotatably arranged relative to the base body, and the rotation center of the operating member is located between the operating end and the locking end.

[0010] Furthermore, the distance from the operating end to the rotation center is greater than the distance from the locking end to the rotation center.

[0011] Furthermore, there are multiple operating members, which can be rotatably arranged, and the operating members are divided into at least one group in pairs, and the two operating members in the same group share the same rotation center and form an X-shaped structure. There are multiple locking members, and the operating members and the locking members are arranged one by one, and locking members are arranged on opposite sides of the base.

[0012] Furthermore, at least one of the buckling parts further includes an elastic member, which abuts against the locking member and provides a restoring force for the locking member to extend out of the base.

[0013] Furthermore, a support arm is provided in the base body, and one end of the elastic member away from the locking member abuts against the support arm.

[0014] Furthermore, a limiting arm is provided in the base body, and the limiting arm is located on the movement path of the operating end. The operating end can abut against the limiting arm to control the movement range of the operating end.

[0015] Furthermore, the two snap-fitting parts include a first snap-fitting part and a second snap-fitting part, the first snap-fitting part has a base, an operating part and a locking part, the base includes a wide side section and a narrow side section connected in sequence, the narrow side section can extend into the second snap-fitting part, the operating part is arranged on the wide side section and the narrow side section, and the locking part is arranged on the narrow side section.

[0016] Furthermore, the second snap-fitting portion has a groove, which includes a wide groove section and a narrow groove section connected in sequence, the narrow groove section is connected to the outer surface of the second snap-fitting portion, the narrow edge section extends into the groove from the narrow groove section, and a step structure is formed between the wide groove section and the narrow groove section. When the first snap-fitting portion and the second snap-fitting portion are snapped into place, the locking piece extends into the wide groove section and abuts against the step structure.

[0017] According to another aspect of the present invention, a safety belt is provided, comprising the safety buckle mentioned above.

[0018] The technical solution of the present invention is applied, by providing the buckle part with an operating member and a locking member, and the operating member and the locking member are divided into two parts, so that transmission can be carried out between the two. When normally locked, the locking member is inserted into the two buckle parts, so that the two buckle parts are buckled and locked together; when unlocking is required, the operator presses the operating end of the operating member, the operating member moves, and the locking end drives the locking member to move, so that the locking member withdraws from one of the buckle parts, so that the two buckle parts are unlocked, so that the two buckle parts can be separated. The above-mentioned setting adopts a separate design of the operating member and the locking member, so that the structures of the two are relatively independent. Whether the locking member is impacted by an external force or the operating member is impacted by an external force, the destructive force will not be transmitted to the other party, thereby improving the stability and safety of the overall structure. When pressing, no large pressing force is required, which is convenient for quick unlocking. Due to the separate design of the operating member and the locking member, in order to increase the strength load, only the strength of the locking member needs to be processed, and no overall adjustment is required, which not only improves safety but also greatly reduces costs.

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0027] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0028] In order to solve the problem of poor stability of the safety buckle in the prior art, the present invention provides a safety buckle and a safety belt, wherein the safety belt has the following safety buckle.

[0029] like Figures 1 to 3A safety lock shown in the figure includes two buckling parts that are arranged to be buckled or separated. At least one buckling part includes a base 10, an operating member 20 and a locking member 30. The operating member 20 is movably connected to the base 10. The operating member 20 has an operating end 21 and a locking end 22. The locking member 30 is arranged at the locking end 22. When the operating member 20 is actuated, the locking member 30 is driven to move to lock or unlock the other buckling part.

[0030] In this embodiment, the buckling part is provided with an operating member 20 and a locking member 30, and the operating member 20 and the locking member 30 are divided into two parts, and transmission can be performed between the two parts. When normally locked, the locking member 30 is inserted into the two buckling parts, so that the two buckling parts are buckled and locked together; when unlocking is required, the operator presses the operating end 21 of the operating member 20, the operating member 20 moves, and the locking end 22 drives the locking member 30 to move, so that the locking member 30 withdraws from one of the buckling parts, thereby unlocking the two buckling parts, so that the two buckling parts can be separated. The above-mentioned setting method adopts a separate design of the operating member 20 and the locking member 30, so that the structures of the two are relatively independent. No matter whether the locking member 30 is impacted by an external force or the operating member 20 is impacted by an external force, the destructive force will not be transmitted to the other party, thereby improving the stability and safety of the overall structure. No large pressing force is required when pressing, which is convenient for quick unlocking. Since the operating member 20 and the locking member 30 are separately designed, in order to increase the strength load, it is only necessary to process the strength of the locking member 30 without overall adjustment, which not only improves safety but also greatly reduces costs.

[0031] The two buckling parts of this embodiment are respectively a first buckling part 50 and a second buckling part 60, wherein the first buckling part 50 has a base 10, an operating part 20 and a locking part 30, and the second buckling part 60 is inserted into the first buckling part 50 to achieve buckling and docking. Of course, both buckling parts can also be set to the structural form of the first buckling part 50, and the locking parts 30 on the two buckling parts are used to stop and achieve the effect of locking and buckling.

[0032] In this embodiment, the base 10 is a shell structure and has an installation cavity. Most of the operating member 20 is accommodated in the installation cavity, and the operating end 21 of the operating member 20 is exposed outside the installation cavity, so that it is convenient for personnel to perform a pressing operation. The locking member 30 is arranged on the base 10, and the locking member 30 can switch between the position of extending and retracting the base 10. When at least a part of the locking member 30 extends to the outside of the installation cavity, the locking member 30 can extend from the first buckle part 50 to the second buckle part 60, thereby realizing the locking between the first buckle part 50 and the second buckle part 60. When the locking member 30 is retracted into the base 10, the locking member 30 withdraws from the second buckle part 60 to avoid the second buckle part 60, and the first buckle part 50 can be unlocked, separated and removed from the second buckle part 60. Of course, the base 10 can be other types of structures such as a frame.

[0033] In this embodiment, the locking member 30 has a slide groove 31, and the locking end 22 extends into the slide groove 31, so that when the operating member 20 is actuated, the locking end 22 can drive the locking member 30 to move by squeezing the side wall of the slide groove 31. In addition, the locking member 30 of this embodiment is movably arranged relative to the base 10. More specifically, the locking member 30 adopts a slider structure, and the moving direction of the locking member 30 is perpendicular to the direction in which the first buckling portion 50 is inserted into the second buckling portion 60. In this way, the locking member 30 can move to extend into the second buckling portion 60 to stop it, thereby achieving a locking effect. As for the locking end 22, there is an angle between the direction in which the locking end 22 extends into the slide groove 31 and the moving direction of the locking member 30. More specifically, the extension direction of the slide groove 31 on the locking member 30 of this embodiment and the moving direction of the locking member 30 have an angle. In this way, the movement of the locking end 22 can contact and squeeze the side wall of the slide groove 31, thereby achieving the effect of driving the locking member 30 to move. At the same time, considering that the movement of the locking end 22 is not necessarily exactly along the moving direction of the locking member 30, the movement of the locking end 22 relative to the locking member 30 has two directional components, one of which is parallel to the moving direction of the locking member 30, and the other is perpendicular to the moving direction of the locking member 30. Therefore, the above-mentioned setting method also provides a movement space for the movement component of the locking end 22 perpendicular to the moving direction of the locking member 30, thereby avoiding the locking end 22 and the locking member 30 from getting stuck.

[0034] Preferably, the direction in which the locking end 22 extends into the slide slot 31, that is, the extending direction of the slide slot 31, is perpendicular to the moving direction of the locking member 30. In other words, the extending direction of the slide slot 31 is parallel to the direction in which the two snap-fitting parts snap together and separate, so that the locking end 22 and the locking member 30 cooperate more smoothly.

[0035] The operating member 20 of this embodiment is rotatably arranged relative to the base 10. More specifically, the operating member 20 adopts a rotating rod, and the rotation center of the operating member 20 is located between the operating end 21 and the locking end 22. In this way, on the one hand, the movement of the operating end 21 can realize the movement of the locking end 22, thereby transmitting the movement of the locking end 22 to the locking member 30 to realize the movement of the locking member 30. On the other hand, the operating member 20 forms a lever structure as a whole, which is easy to operate and has better stability.

[0036] In an embodiment not shown in the figure, the operating member 20 is arranged in a movable manner, as long as the moving direction of the operating member 20 is not perpendicular to the moving direction of the locking member 30 .

[0037] Preferably, the distance from the operating end 21 to the rotation center is greater than the distance from the locking end 22 to the rotation center, so that the operating member 20 forms a labor-saving lever structure, and the operation is more labor-saving and convenient.

[0038] In this embodiment, there are multiple operating members 20, and the operating members 20 can be rotatably arranged. The operating members 20 are divided into at least one group in pairs, and the two operating members 20 in the same group share the same rotation center and form an X-shaped structure. In this embodiment, two operating members 20 are arranged, and the two operating members 20 form an X-shaped structure as a group. The center of the X-shaped structure is the rotation center of the operating member 20. The two oblique lines of the X-shaped structure are two operating members 20 respectively, and the operating ends 21 of the two operating members 20 are adjacent and located on the same side. In this way, the operator can manually pinch the operating ends 21 of the two operating members 20 at the same time, and the two operating ends 21 move in a direction close to each other, so that the two locking ends 22 also move in a direction close to each other. At the same time, multiple locking members 30 can also be arranged, and the operating members 20 and the locking members 30 are arranged one by one, and the locking members 30 are arranged on both opposite sides of the base 10. In order to cooperate with the operating member 20, two locking members 30 are also provided in this embodiment, and the two locking members 30 are respectively provided at the locking ends 22 of the two operating members 20, so that the two locking members 30 lock both sides at the same time, and the locking stability is higher, and when the two locking ends 22 move synchronously, the two locking members 30 can be driven to retract into the base 10 at the same time, so as to achieve the function of simultaneously unlocking the second buckling part 60. Since there are multiple operating members 20 and locking members 30, even if one is violently damaged, the other can remain locked, which greatly improves the stability, reliability and safety of the safety lock.

[0039] In this embodiment, at least one snap-fitting portion further includes an elastic member 40, which can be a spring or other component. One end of the elastic member 40 abuts against the base 10, and the other end abuts against the locking member 30, so that the elastic member 40 can provide a reset force for the locking member 30 to extend out of the base 10. When the operating member 20 is not operated, the elastic member 40 can keep the locking member 30 in a position extending out of the base 10, thereby achieving the effect of automatic locking and maintaining locking, thereby improving safety and stability.

[0040] In this embodiment, a support arm 11 is further provided in the base 10, the support arm 11 extends into the installation cavity, and the support arm 11 is located between the two locking members 30, so that the ends of the two elastic members 40 away from the locking members 30 are both in contact with the support arm 11. The support arm 11 not only provides support for the elastic member 40, but also serves to limit the movement of the locking member 30, so that the locking member 30 abuts against the support arm 11 when it is retracted into the base 10, thereby preventing the locking member 30 from moving too far. The movement of the locking member 30 extending out of the base 10 is itself limited by the locking end 22, so the limiting effect in the extension direction has been achieved.

[0041] Similar to the support arm 11, the present embodiment further has a limit arm 12 disposed in the base 10. The limit arm 12 is located on the movement path of the operating end 21. The limit arm 12 in the present embodiment is located between the operating ends 21 of the two operating members 20. In this way, when a person pinches the operating end 21, the operating end 21 moves into the base 10 until it abuts against the limit arm 12, thereby achieving the purpose of controlling the movement range of the operating end 21. Of course, in addition to cooperating with two operating members 20 at the same time, the limit arm 12 may also be provided with multiple limit arms 12, and each operating member 20 is limited and stopped by a different limit arm 12. In the present embodiment, since an X-shaped structure is formed between the two operating members 20, the support arm 11 and the limit arm 12 in the present embodiment are respectively located on opposite sides of the base 10.

[0042] In this embodiment, the base 10 of the first buckling part 50 includes a wide side section 13 and a narrow side section 14 connected in sequence. It should be noted that the width is measured by the width of the side perpendicular to the buckling and separation direction of the buckling part, and the extension direction of the section is extended in the direction of the buckling and separation of the buckling part. Among them, one side of the wide side section 13 can be connected to other components, such as the belt body of the safety belt, and the other side of the wide side section 13 is connected to the narrow side section 14, and the narrow side section 14 can extend into the second buckling part 60. In this way, when buckled and locked, the wide side section 13 is located outside the second buckling part 60, and the narrow side section 14 is located inside the second buckling part 60. Therefore, in this embodiment, the operating member 20 is arranged on the wide side section 13 and the narrow side section 14. More specifically, the operating end 21 of the operating member 20 is located on the side of the wide side section 13, and the locking end 22 is located in the narrow side section 14. The locking member 30 is arranged on the narrow side section 14 and cooperates with the locking end 22. In this way, the operating end 21 can be operated, the locking function of the locking member 30 can be realized, and the operating member 20 can also drive the locking member 30 to realize the function.

[0043] In order to match the structure of the first buckling portion 50, the second buckling portion 60 of this embodiment has a groove 61. Similar to the wide side section 13 and the narrow side section 14, the groove 61 of this embodiment includes a wide groove section 62 and a narrow groove section 63 connected in sequence, and the width and narrowness standards are the same as mentioned above. Among them, the narrow groove section 63 is communicated with the outer surface of the second buckling portion 60, and the narrow side section 14 extends from the narrow groove section 63 into the wide groove section 62 of the groove 61, and a step structure 64 is formed between the wide groove section 62 and the narrow groove section 63. When the first buckling portion 50 and the second buckling portion 60 are buckled, the narrow side section 14 extends into the groove 61 until the end of the wide side section 13 abuts against the outer surface of the second buckling portion 60, indicating that it is extended into place. At this time, a part of the narrow side section 14 is located in the narrow groove section 63, and the other part is located in the wide groove section 62, and the locking member 30 is located in the wide groove section 62. Under the action of the elastic member 40, the locking member 30 extends out of the base 10 and extends into the wide groove section 62. At this time, the locking member 30 abuts against the step structure 64 in the groove 61, so that the first buckling portion 50 cannot withdraw from the second buckling portion 60, thereby realizing the buckling and locking between the first buckling portion 50 and the second buckling portion 60.

[0044] In this embodiment, guiding slopes are provided on the side of the narrow side section 14 away from the wide side section 13 and the side of the locking member 30 away from the wide side section 13 , so that the first buckling portion 50 and the second buckling portion 60 can fit more smoothly.

[0045] It should be noted that the specific structure of the buckle portion is not limited to the above-mentioned configuration of this embodiment, and the specific structure can be changed accordingly as needed. The safety lock buckle of this embodiment can be applied to various types of safety belts for binding transportation as needed.

[0046] It should be noted that, the multiple in the above embodiments refers to at least two.

[0047] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0048] 1. Solve the problem of poor stability of the safety lock in the prior art;

[0049] 2. The operating part and the locking part are designed to be separated, thereby improving the stability and safety of the overall structure;
