The insertion space 16 and the pressing shaft 131 may be located on different surfaces of the buckle body 11, or may be located on the same surface. In addition, in an embodiment of the present invention, the material of the locking buckle 10 is a metal material. Because the metal material has certain strength, the possibility that the locking buckle 10 is damaged can be reduced, and the service life of the locking buckle 10 can be prolonged. Of course, the present application is not limited thereto, and in other embodiments, the material of the locking buckle 10 may also be plastic.

When the locking buckle 10 according to the technical solution of the present invention is used for connecting the first strap 31 and the second strap 33 of the strap structure 100, the buckle body 11 may be connected to one end of the first strap 31, and one end of the second strap 33 passes through the insertion space 16 defined by the buckle 15 and the buckle body 11. Then, the fastener 15 is rotated to cover and inserted into the fastening hole 151 of the fastener 15 through the fastening member 133, so that the fastener 15 is fixed in a limited manner relative to the pressing shaft 131 and is in a locked state.

In addition, the pressing shaft 131 of the locking buckle 10 in this embodiment serves to connect the buckling member 15, and can also serve as an unlocking button to be pressed and driven to drive the clamping member 133 to unlock the buckling member 15. The structure of the locking buckle 10 can be simplified without separately arranging a connecting structure of the opposite buckling parts 15 and an unlocking structure of the opposite buckling parts 15 on the locking buckle 10, so that the manufacturing cost of the locking buckle 10 is reduced, and the structure of the locking buckle 10 is more compact, so that the whole volume of the locking buckle 10 is reduced.

Referring to fig. 6 and 7, in an embodiment of the present invention, the position-limiting assembly 13 further includes a connecting member 135, the connecting member 135 connects the pressing shaft 131 and the engaging member 133, and the pressing shaft 131 drives the engaging member 133 through the connecting member 135.

It can be understood that the pressing shaft 131 and the snap member 133 are connected by the connecting member 135 so that they have a connection fixed relationship. At this moment, when the pressing shaft 131 is pressed to be driven, the clamping piece 133 can be timely driven therewith, so that the timeliness and the stability of the driving of the clamping piece 133 are favorably improved. Simultaneously, so set up, also make this press axle 131 and joint piece 133 to connect through connecting piece 135 and form an overall structure, this moment when will press axle 131 to install on detaining body 11, can once only accomplish this spacing subassembly 13 holistic installation to the convenience of installing has improved it. Of course, it should be noted that the present application is not limited to this, and when the connecting member 135 is not provided in the limiting assembly 13, one end of the pressing shaft 131 may be abutted against the snap-in member 133, and is abutted and driven when being pressed and driven.

Referring to fig. 6 and 7, in an embodiment of the present invention, the locking buckle 10 further includes an elastic member 17, and the elastic member 17 is disposed on the buckle body 11; the connecting member 135 is defined to have two opposite surfaces, the pressing shaft 131 and the engaging member 133 are located on one of the two opposite surfaces of the connecting member 135, and the elastic member 17 elastically abuts against the other of the two opposite surfaces of the connecting member 135.

It can be understood that the elastic member 17 has a certain elasticity, so that when the pressing shaft 131 is pressed, it can be compressed by the connecting member 135, and generates a corresponding deformation elastic force. When the pressing force for pressing the shaft 131 is removed, the pressing shaft 131 can be restored in time by the deforming elastic force of the elastic member 17. Meanwhile, the elastic member 17 elastically abuts against the connecting member 135, so that the engaging member 133 is urged in the direction of being inserted into the engaging hole 151 of the engaging member 15. So guarantee the stability of joint spare 133 and joint hole 151 looks joint to guaranteed the locking effect to closure 15 and to realizing the stable connection to first area body 31 and second area body 33. The pressing shaft 131 and the engaging member 133 are located on one of two opposite surfaces of the connecting member 135, so that the two members can be located on the same side of the connecting member 135 to be more compactly distributed, thereby being beneficial to reducing the space occupied by the position limiting assembly 13 on the buckle body 11. At this time, the connecting member 135 may have an elongated column structure, so that the pressing shaft 131 and the engaging member 133 are connected to one surface of the connecting member 135 and the elastic member 17 abuts against the other surface of the connecting member 135. The elastic member 17 is a spring, which has the advantages of relatively good elasticity and low cost, so that the elastic member 17 can stably reset the pressing shaft 131, and the manufacturing cost of the elastic member 17 is reduced. Of course, the elastic member 17 may be an elastic sheet or a plastic member with certain elasticity. In addition, it should be noted that the present application is not limited thereto, and in other embodiments, the pressing shaft 131 and the clamping member 133 may be located on two opposite sides of the connecting member 135. In this case, the connecting member 135 may include a left end segment, a middle segment, and a right end segment. Wherein, the left end segment body is a telescopic rod, and one end of the left end segment body is rotatably connected with a pressing shaft 131; one end of the middle section body is connected with one end of the left end section body far away from the pressing shaft 131, and the middle part of the middle section body is rotatably connected with the buckle body 11; the right end section body is also a telescopic rod, one end of the right end section body is connected with one end of the middle section body, which is far away from the left end section body, and the other end is rotatably connected with the clamping piece 133. Thus, after the pressing shaft 131 is pressed, the connecting member 135 can be driven to disengage from the engaging hole 151 along the direction deviating from the pressing direction of the pressing shaft 131. In addition, it is also possible that the elastic member 17 is elastically connected to the surface of the connecting member 135 provided with the pressing shaft 131. At this time, when the pressing shaft 131 is driven to press, the elastic member 17 stretches to generate a corresponding deformation elastic force to subsequently drive the pressing shaft 131 to reset. When the locking buckle 10 is not additionally provided with the elastic member 17, the clamping member 133 can be connected by an elastic sheet body, and includes a first sheet body and a second sheet body, one end of the first sheet body is used for being inserted into the clamping hole 151 of the buckling member 15, one end of the second sheet body is connected to the first sheet body, the other end of the second sheet body is fixed to the buckling member 15, and meanwhile, one end of the connecting member 135, which is far away from the pressing shaft 131, is connected to the second sheet body or is abutted against the second sheet body. Therefore, when the pressing shaft 131 is pressed and driven, the connecting member 135 can drive the second sheet body of the engaging member 133 to move, and further drive the first sheet body connected with the second sheet body to be separated from the engaging hole 151 of the fastener 15. The second sheet body is deformed when being driven by the connecting member 135 to generate a corresponding deformation elastic force, and then the second sheet body can drive the pressing shaft 131 to reset.

Referring to fig. 6 and 7, in an embodiment of the present invention, the connecting member 135 is protruded with a mounting post 137 on a surface facing the elastic member 17, and an end of the mounting post 137 away from the connecting member 135 is inserted into the elastic member 17.

It can be understood that, the mounting post 137 can limit and guide the elastic member 17, so as to ensure that the elastic member 17 is accurately compressed along the pressed direction when the pressing shaft 131 is pressed, so that the pressing shaft 131 is accurately driven to reset by generating a reverse deformation elastic force in the following. Meanwhile, the arrangement also simplifies the connection between the elastic part 17 and the connecting part 135, and the elastic part 17 is directly sleeved on the mounting column 137 on the connecting part 135, thereby being beneficial to improving the convenience of mounting the elastic part 17.

Referring to fig. 6 and 7, in an embodiment of the utility model, the number of the limiting components 13 is two, the defining buckle body 11 has two opposite sides, the two limiting components 13 are respectively located at the two opposite sides of the buckle body 11, the two pressing shafts 131 of the two limiting components 13 are arranged back to back, the elastic member 17 abuts between the two connecting members 135 of the two limiting components 13, the fastening member 15 is rotatably sleeved on the two pressing shafts 131 and is provided with two fastening holes 151, and the two fastening members 133 of the two limiting components 13 are respectively inserted into the two fastening holes 151.

It will be appreciated that the two retainer assemblies 13 are arranged such that opposite sides of the fastener 15 can be rotatably coupled to the two pressing shafts 131, thereby facilitating improved rotational coupling stability of the fastener 15. Meanwhile, the two clamping holes 151 in the buckling piece 15 can be inserted and limited through the two clamping pieces 133 in the two limiting assemblies 13, so that the buckling piece 15 can be limited and locked on the two opposite sides, and the locking effect is improved. At this time, the elastic member 17 is elastically abutted between the two connecting members 135 of the two position limiting assemblies 13, so that the two pressing shafts 131 can be reset after being pressed by one elastic member 17, the number of the elastic members 17 is reduced, and the structure of the locking buckle 10 is simplified. Furthermore, the two pressing shafts 131 are reset through the elastic member 17, so that the two pressing shafts 131 can be ensured to be uniformly elastically abutted, and the consistency of the pressing hand feeling of pressing the two pressing shafts 131 can be ensured. Of course, the present application is not limited thereto, and in other embodiments, only one set of the limiting assemblies 13 may be provided. At this time, in the case that the pressing shaft 131 and the engaging member 133 are located on the same side of the connecting member 135, one side of the fastener 15 is rotatably connected to the pressing shaft 131 and is engaged and locked with the engaging member 133. Or, in the case that the pressing shaft 131 and the locking member 133 are located on opposite sides of the connecting member 135, one side of the fastener 15 is rotatably connected to the pressing shaft 131, and the other side is locked to the locking member 133.

In an embodiment of the present invention, the connecting member 135, the pressing shaft 131 and the engaging member 133 are an integral structure.

It can be understood that the mounting cavity 111 provides a space for accommodating the position limiting component 13, so that the mounting on the buckle body 11 is more compact and the occupied space is reduced, thereby being beneficial to further reducing the overall size of the locking buckle 10. Meanwhile, the cavity wall of the installation cavity 111 can also play a certain role in isolation and protection for the limiting component 13, so that the possibility that the limiting component is damaged by foreign objects is reduced, and the service life of the limiting component 13 is prolonged. And the sliding hole 113 communicating with the mounting cavity 111 is provided so that the pressing shaft 131 can be mounted and guided through the sliding hole 113, thereby simplifying the mounting structure of the pressing shaft 131. Wherein, the shape of installation cavity 111 can be square or rectangle to make its shape comparatively regular and be convenient for machine-shaping, also can carry out better holding to pressing axle 131, connecting piece 135, joint piece 133 and elastic component 17 of spacing subassembly 13 simultaneously. In the case where the pressing shaft 131 and the catching piece 133 are located on the same side of the connecting piece 135, the sliding hole 113 and the passing hole 115 may be located on the same side wall surface of the buckle body 11. And in the case that the pressing shaft 131 and the catching piece 133 are located on opposite sides of the connecting piece 135, the sliding hole 113 and the passing hole 115 may be located on opposite side wall surfaces of the buckle body 11. In addition, it should be noted that, the present application is not limited to this, and in other embodiments, when the buckle body 11 is not formed with the installation cavity 111, the limiting component 13 may also be disposed on the outer surface of the buckle body 11 adjacent to the insertion space 16, and the pressing shaft 131 of the limiting component 13 may be slidably inserted on the guide cylinder protruding from the buckle body 11.

Referring to fig. 1 and 4, in an embodiment of the present invention, the fastening member 15 includes a side plate 153 and a top plate 157, the side plate 153 is rotatably sleeved on the pressing shaft 131 penetrating from the sliding hole 113 to the outside and is provided with a fastening hole 151, and the side plate 153 is further limited by the fastening body 11 in the rotating shaft direction; the top plate 157 is connected to the side plate 153 and forms an included angle with the side plate 153, the top plate 157, the side plate 153 and the buckle body 11 enclose to form an inserting space 16, and when the buckling piece 15 is located at a locking state, the top plate 157 can abut against and limit the second belt body 33 passing through the inserting space 16.

It is understood that the fastening member 15 is rotatably connected to the pressing shaft 131 through the side plate 153, so that the inserting space 16 and the pressing shaft 131 can be distributed on different surfaces of the fastening body 11. In this case, the distribution of the locking buckle body 11 can be made more compact, which is advantageous for reducing the overall size of the locking buckle 10. Meanwhile, the top plate 157 can have a relatively large abutting area with the second belt body 33, so that the stability of abutting limit is improved. The number of the side plates 153 may be one, that is, the fastener 15 has a substantially L-shape. At this time, one of the limiting assemblies 13 is correspondingly arranged. The buckle body 11 also only needs to be provided with a sliding hole 113 for the pressing shaft 131 to pass through and a passing hole 115 for the clamping member 133 to pass through on one side wall surface. Of course, there may be two side panels 153, and two side panels 153 are connected to opposite sides of the top panel 157, i.e., the fastener 15 is substantially U-shaped. At this moment, the two limiting assemblies 13 are correspondingly arranged and are respectively located on two opposite sides of the buckle body 11, and the buckle body 11 needs to be correspondingly provided with a sliding hole 113 for the pressing shaft 131 to pass through and a passing hole 115 for the clamping piece 133 to pass through on the wall surfaces of the two opposite sides, so that the two side plates 153 can be respectively connected with the two pressing shafts 131 in the two limiting assemblies 13 in a rotating manner and clamped and fixed with the two clamping pieces 133. Meanwhile, the fastening member 15 can be abutted against two opposite side walls of the fastening body through the two side plates 153, so that the fastening member 15 is limited in the axial direction of rotation by the fastening body 11. Of course, an arc-shaped guide groove is provided on the side plate 153, a T-shaped block is provided on the buckle body 11, and the T-shaped block is slidably fitted in the guide groove, so that the buckle body 11 may limit the buckling member 15 in the axial direction of rotation. Alternatively, a link is rotatably connected between the top plate 157 and the fastening body to realize that the rotation circumferential direction is rotatable and the rotation axial direction is limited. The fastener 15 may include a top plate 157, and a rotating arm and a connecting arm connected to the top plate 157, wherein one end of the rotating arm away from the top plate 157 is rotatably connected to the pressing shaft 131, and one end of the connecting arm away from the top plate 157 is provided with a locking hole 151. Or, the fastening member 15 only includes the top plate 157, and at this time, the top plate 157 and one surface of the fastening body 11 are oppositely disposed and enclose to form the inserting space 16. At this time, the sliding hole 113 for the pressing shaft 131 to pass through and the passing hole 115 for the fastening member 133 to pass through may be both located on the surface of the buckle body 11 facing the fastening member 15 and located on opposite sides of the buckle body 11, so that the middle area is better for the second belt body 33 to pass through.

Referring to fig. 1 and 4, in an embodiment of the present invention, the top plate 157 is provided with an abutting column 158 protruding in the inserting space 16, and when the fastener 15 is in the locked state, the abutting column 158 can limit the abutting of the second strap 33 passing through the inserting space 16.

It can be understood that the abutting portion can be embedded into the second strap 33, and the abutting force of the fastener 15 to the second strap 33 can be increased, so as to be beneficial to improving the abutting and limiting effect on the second strap 33, so that the first strap 31 and the second strap 33 can be stably connected. The abutting column 158 can be disposed in a long shape extending along the rotating axial direction of the fastener 15, so as to increase the abutting area of the second strap 33, and further improve the abutting limiting effect. Of course, the present application is not limited thereto, and in other embodiments, the abutment post 158 may have a cylindrical shape.

Referring to fig. 6, in an embodiment of the utility model, the side plate 153 has a limiting post 155 protruding from a surface of the buckle body 11 having the sliding hole 113, the buckle body 11 has an arc-shaped hole 117 at a position corresponding to the limiting post 155, a center point of the arc-shaped hole 117 is located on an axis of the pressing shaft 131, and the limiting post 155 is inserted into the arc-shaped hole 117.

It can be understood that, since the arc-shaped hole 117 has a limiting and guiding function for the limiting post 155, the limiting post 155 can only slide along the extending direction of the arc-shaped hole 117 during the rotation process of the fastening member 15, and can only slide to two ends of the arc-shaped hole 117. Therefore, the buckling piece 15 connected with the limiting column 155 is matched with the arc-shaped hole 117, and the rotating stability in the opening and closing processes can be improved. Meanwhile, the locking device has a limiting function on the rotation stroke of the buckling piece 15, so that when the buckling piece 15 covers the corresponding rotation stroke, the clamping hole 151 corresponds to the clamping connection position, and the locking efficiency of the buckling piece 15 is improved; when the fastener 15 is opened for a corresponding rotation stroke, the rotation angle of the fastener 15 is not too large, so that the end of the fastener 15 close to the pressing shaft 131 does not interfere with the pressing of the fastener body 11 and the second strap 33. The arc-shaped hole 117 may be a through hole structure communicating with the mounting cavity 111, or may be a blind hole structure not communicating with the mounting cavity 111. The limiting column 155 and the buckle body 11 may have only an abutting relationship between the limiting column 155 and the hole wall of the arc-shaped hole 117, or may have a snap-fit relationship. That is, the side circumference of the position-limiting post 155 may have a groove, and the partial structure of the buckle body 11 formed with the arc-shaped hole 117 is embedded into the groove, so that the position-limiting post 155 is also limited in the axial direction of rotation, and further the buckling member 15 is also limited in the axial direction of rotation and can only be opened or closed in the axial direction of rotation.

Referring to fig. 5, in an embodiment of the present invention, an avoiding opening 159 is formed at an end of the connection between the top plate 157 and the side plate 153 close to the pressing shaft 131, so as to avoid the buckle body 11 and the second belt 33 passing through the inserting space 16 when the buckle 15 rotates relative to the pressing shaft 131.

At this time, the escape 159 allows the top panel 157 and the side panel 153 to form a notch at this portion, so as not to cause interference extrusion to the buckle body 11 and the second strap 33 during the movement process close to the buckle body 11 and the second strap 33, thereby being beneficial to further ensuring the stability and safety of the opening of the buckle 15 during rotation. Of course, the present application is not limited thereto, and in other embodiments, when there is a relatively large distance gap between the top panel 157 of the fastener 15 and the fastener body 11, the connection position of the top panel 157 and the side panel 153 at the end close to the pressing shaft 131 may not be provided with the avoiding opening 159.

At this time, the abutting column 158 can stably limit the position of the second tape 33 in the inserting direction in which the second tape 33 passes through the inserting space 16 (that is, in the longitudinal direction of the second tape 33), thereby improving the effect of limiting the position of the second tape 33 by the fastener 15. Further, the number of the positioning holes 331 may be multiple, and the positioning holes 331 are spaced along the length direction of the second tape body 33. When the wearing length of the belt structure 100 is adjusted in this way, the abutment post 158 can be fitted into a different positioning hole 331 to perform abutment stop.
