Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of connecting buckle, especially to a connecting buckle with quick locking and unlocking device. BACKGROUND

[0002] With the continuous improvement of living standards, more and more people keep pets at home, and people with pets can often be seen in living areas, parks and squares. In order to ensure the safety of pets and pedestrians and vehicles on the road, pet leashes are usually used as traction control.

[0003] The commonly used pet leash generally consists of a handle, a leash and a collar. When in use, the collar is put around the pet's neck or body, and then the leash is connected to the collar through a connecting buckle. The commonly used connecting buckle on the market basically adopts a clasp lock or a plug-in lock. Although these two types of locks can basically meet the requirement of easy disassembly, they still have some defects. Specifically, both types of locks need to be pressed closely before they can be unlocked, so that the pet owner cannot rescue the pet in time when something unexpected happens. For example, when the owner takes the pet into an elevator, the pet may run into or out of the elevator door in an instant, and the owner may have closed the elevator door before he realizes it. In this case, the pet leash is clamped by the elevator door, and the owner cannot release the connection between the leash and the collar in time, which may result in the pet being trapped in the elevator and being forced to pull the leash, and even the pet being strangled to death. Another example is that during the training of dogs, the owner and the training dog need to complete some tasks separately, which often requires the leash to be released while running. However, the commonly used clasp lock or plug-in lock needs to be pressed closely by the owner before it can be released. Therefore, the owner and the training dog need to stop and release the leash before they can complete the task separately, which is time-consuming. If the training dog runs directly with the leash, the leash may be entangled with other objects, which may prevent the training dog from moving. If this happens during a search and rescue operation, it may result in a delay in search and rescue and even cause some tragedies.

[0004] Therefore, the present inventor has conducted in-depth research on the above problems and thus conceived the present application. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0032] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0033] Embodiment one: refer to Figures 1 to 7

[0034] A connecting buckle with a quick locking and unlocking device can be applied to the binding and fastening of various articles, and the rope is more widely used on articles such as backpacks, water bottles, keys, or pet traction ropes, etc. By applying the buckle to the rope, the rope can be easily embedded or disengaged by pressing the buckle, and the rope can be easily stretched and adjusted, and the beauty and texture of the rope can be highlighted.

[0035] For the convenience of description, the end of the buckle body 1 away from the connecting ring 2 is defined as the first end, and the end of the buckle body 1 close to the connecting ring 2 is defined as the second end.

[0036] The embodiment includes a buckle body 1 and a connecting ring 2 connected to the buckle body 1. It is worth noting that the connecting ring 2 in this embodiment can be fixedly connected to the second end of the buckle body 1, or can be rotatably connected to the second end of the buckle body 1. When the connecting ring 2 is rotatably connected to the buckle body 1, it is consistent with the rotating connection method in the Chinese utility model patent (patent number: CN212728442U), which will not be described in detail here.

[0037] The buckle body 1 includes a first connecting piece 11 and a second connecting piece 12 connected to each other, the second end of the first connecting piece 11 and the second end of the second connecting piece 12 are fixedly connected through a connecting block 13, the first connecting piece 11, the second connecting piece 12 and the connecting block 13 are integrally formed, and the first connecting piece 11, the second connecting piece 12 and the connecting block 13 together form a step 14. The integrally formed buckle body 1 in this embodiment is more firm and reliable, and will not be offset or fall off due to the shaking of the rope when combined with the rope, avoiding accidents caused by falling off, and being firm and durable.

[0038] The first end of the first connecting piece 11 and the first end of the second connecting piece 12 are both provided with a notch 15, and the notch 15 is in the shape of a U. The U-shaped notch 15 is used to accommodate articles such as backpacks, water bottles, keys, or pet traction ropes, etc.

[0039] The first connecting sheet 11 and the second connecting sheet 12 movably arrange a lock assembly 3 for opening and closing the gap 15, the lock assembly 3 includes a first hook sheet 31 and a second hook sheet 32 arranged in mirror image and an elastic member for connecting the first hook sheet 31 and the second hook sheet 32. Specifically, the elastic member can adopt a double torsion spring 33, the double torsion spring 33 includes two spring bodies 331 arranged in symmetry, two driving arms 332 and a connecting arm 333 connecting the two spring bodies 331, the connecting arm 333 is wound to form a connecting ring 334 in the middle. In use, the gap 15 is fixed on the pet collar or pet suit, and then the first hook sheet 31 and the second hook sheet 32 close the gap 15, so that the pet collar or pet suit is limited in the gap 15, that is, the locking connection between the pet collar or pet suit and the utility model is completed. When it is needed to unlock and release the pet, the first hook sheet 31 and the second hook sheet 32 are unlocked by pulling the traction rope, so that the first hook sheet 31 and the second hook sheet 32 are in an open state, and then the pet collar or pet suit is separated from the limitation of the gap 15, that is, the pet collar or pet suit and the embodiment are disconnected.

[0040] Further, the middle part of the step 14 extends in the second end direction to have a groove 141 for placing the connecting ring 334 and the connecting arm 333, the connecting ring 334 and the connecting arm 333 are movably arranged in the groove 141, and the two spring bodies 331 are arranged on the step 14. The design of the step 14 limits the movement of the two spring bodies 331 in the second end direction. Due to the characteristics of the double torsion spring 33, when the two spring bodies 331 abut against the step 14, the connecting ring 334 and the connecting arm 333 can move in the groove 141 at this time, avoiding the connecting ring 334 and the connecting arm 333 abutting against the step 14, which causes damage to the double torsion spring 33. That is, when the torsion of the double torsion spring 33 is 0, the two spring bodies 331 only contact the step 14 (at this time, the gap 15 is in a closed state); when the double torsion spring 33 is subjected to a pulling force in the second end direction, the connecting ring 334 and the connecting arm 333 move in the second end direction in the groove 141, because the double torsion spring 33 is limited by the step 14 and cannot move in the second end direction, so that the two driving arms 333 move in opposite directions (at this time, the gap 15 is in an open state). It is worth noting that the double torsion spring 33 in the embodiment is integrally wound.

[0041] The first hook piece 31 and the second hook piece 32 each comprise a movable end 311 arranged in a first end direction, a connecting end 312 arranged in a second end direction, and a driving end arranged between the movable end 311 and the connecting end 312, the two connecting ends 312 are rotatably installed to the first connecting piece 11 and the second connecting piece 12 through a connecting shaft 5, and the first hook piece 31 and the second hook piece 32 are overlapped with each other, that is, the connecting shaft 5 passes through the first connecting piece 11, the first hook piece 31, the second hook piece 32, and the second connecting piece 12 in sequence, and the two movable ends 311 are staggered and arranged in an openable and closable state at the gap 11.

[0042] Further, the two driving ends are each provided with a through hole 313 for the end of the driving arm 332 to pass through, and the two driving arms 332 are respectively inserted into the through hole 313 of the first hook piece 31 and the through hole 313 of the second hook piece 32, so that when the two driving arms 333 move in the direction of approaching or moving away, the first hook piece 31 and the second hook piece 32 are driven to rotate around the connecting shaft 5 in the direction of approaching or moving away, and under the action of the torsion of the double torsion spring 33, the two movable ends 311 are closed (as shown in Figures 1 to 3 Further, the two driving ends are each provided with a through hole 313 for the end of the driving arm 332 to pass through, and the two driving arms 332 are respectively inserted into the through hole 313 of the first hook piece 31 and the through hole 313 of the second hook piece 32, so that when the two driving arms 333 move in the direction of approaching or moving away, the first hook piece 31 and the second hook piece 32 are driven to rotate around the connecting shaft 5 in the direction of approaching or moving away, and under the action of the torsion of the double torsion spring 33, the two movable ends 311 are closed (as shown in Figures 4 to 5 Further, the two driving ends are each provided with a through hole 313 for the end of the driving arm 332 to pass through, and the two driving arms 332 are respectively inserted into the through hole 313 of the first hook piece 31 and the through hole 313 of the second hook piece 32, so that when the two driving arms 333 move in the direction of approaching or moving away, the first hook piece 31 and the second hook piece 32 are driven to rotate around the connecting shaft 5 in the direction of approaching or moving away, and under the action of the torsion of the double torsion spring 33, the two movable ends 311 are closed (as shown in

[0043] For the convenience of description, the first hook piece 31 and the second hook piece 32 are the same in structure, and the first hook piece 31 will be described below.

[0044] Further, the first hook piece 31 and the second hook piece 32 each present a semi-closed type, and in this embodiment, can present a C type, and the first hook piece 31 and the second hook piece 32 each comprise a trigger part 314 connected with the connecting end 312, the trigger part 314 is arranged at the outer edge of the corresponding connecting end 312, and the end extends outward. When the first connecting piece 11 and the second connecting piece 12 present a closed state, the inner wall of the C-shaped first hook piece 31 and the inner wall of the C-shaped second hook piece 32 enclose a closed ring, and are flush with the inner wall of the U-shaped first connecting piece 11 or the second connecting piece 12; the outer wall of the first hook piece 31 and the outer wall of the second hook piece 32 are flush with the outer wall of the first connecting piece 11 and the inner wall of the second connecting piece 12, as shown in Figures 1 to 3When the contact object (i.e. the backpack, the water bottle, the key or the pet leash and other articles) contacts the trigger part 314 of the first hook piece 31 and the trigger part 314 of the second hook piece 32, the static state of the first hook piece 31 and the second hook piece 32 is broken (i.e. the torsion of the double torsion spring 33 changes), the double torsion spring 33 generates the tangential force on the first hook piece 31 and the second hook piece 32, so that the first hook piece 31 and the second hook piece 32 rotate in the opposite direction along the connecting shaft 5 and form the closed loop with the notch 15, at this time, the contact object (i.e. the backpack, the water bottle, the key or the pet leash and other articles) is placed in the closed loop and the buckle body 1 is connected. It is worth noting that the buckle body 1 is completely opened only when the first hook piece 31 and the second hook piece 32 are deflected to the static angle on both sides of the buckle body 1, and when only one of the first hook piece 31 and the second hook piece 32 is deflected to the static angle, it will also be reset by the tangential force, which is safer to use. In addition, it is worth noting that when the utility model is in the open state, if the user swings the buckle outward, the first hook piece 31 and the second hook piece 32 will break the static state of the double torsion spring 33 under the action of inertia and gravity, at this time, the first hook piece 31 and the second hook piece 32 will also rotate in the opposite direction along the connecting shaft 5 and form the closed loop with the notch 15, that is, the closed state of the buckle is restored.

[0045] Further, the two driving ends are provided with the limiting grooves (not shown in the figure) for the driving arms 332, the driving arms 332 are movably arranged in the corresponding limiting grooves, the limiting grooves include the first limiting edge for limiting the first hook piece 31 or the second hook piece 32 from being excessively opened and the second limiting edge for limiting the first hook piece 31 or the second hook piece 32 from being excessively closed, and the two through holes 313 are correspondingly arranged on the two limiting grooves.

[0046] In the present application, the driving connecting arm 333 is arranged on the connecting ring 334 to move towards / away from the second end direction and drive the two driving arms 332 to generate elastic force to make the two driving ends have the tendency to move in the opposite or same direction. It is worth mentioning that the driving assembly in the present embodiment mainly drives the first hook piece 31 and the second hook piece 32 to move in the opposite direction, that is, to achieve the opening action of the buckle by pulling the driving assembly, while the closing action of the buckle is achieved by triggering the two trigger parts 314 or swinging the buckle to make the first hook piece 31 and the second hook piece 32 move in the same direction. That is, in the present embodiment, by connecting the traction rope (not shown in the figure) to the driving assembly, pulling the traction rope can drive the connecting arm 333 to move towards the second end direction, and under the characteristics of the double torsional spring 33, the two driving arms 332 move in the opposite direction, that is, the two movable ends 311 move in the opposite direction, complete the opening action of the buckle connecting block, and release the restriction of the pet dog collar arranged at the notch 15, realize the unlocking of the pet traction rope connecting device, when the pet rope is stuck in the elevator and the pet is lifted, the present application can be remotely unlocked by pulling the driving assembly, so that the pet can be rescued in time to avoid the pet being stuck or injured in the elevator; moreover, for the trainer and the trainee, the trainer can directly unlock the training dog while running, without the need to stop and manually unlock, which can effectively save the time of unlocking the training dog and strive for the time to complete the task; for the search and rescue dog, the action and speed of the search and rescue dog are often faster than those of the search and rescue personnel, when the search and rescue dog catches the breath of the searched personnel, the search and rescue dog will have a momentary rush-out action, and the search and rescue personnel can unlock the search and rescue dog in an instant, so that the search and rescue dog can catch the smell of the searched personnel more quickly, which can effectively save the search time, and because the search area is often a disaster area or a remote area, the terrain is not flat, and accidents such as the search and rescue personnel falling down due to the sudden rush-out of the search and rescue dog often occur, after using the present application, the search and rescue personnel can quickly unlock the search and rescue dog to avoid being dragged by the search and rescue dog and falling down.

[0047] Further, as shown in Figure 6 and Figure 7 , the detailed structure of the driving assembly will be described in detail as follows:

[0048] The driving assembly includes a connecting rod 61 connected with the connecting arm 333, the first connecting piece 11 and the second connecting piece 12 are both provided with a waist-shaped hole 16 for the connecting rod 61 to pass through, the waist-shaped hole 16 is arranged along the length direction of the buckle body 1, and the two ends of the connecting rod 61 are respectively arranged on the corresponding waist-shaped hole 16 and can move along the length direction of the waist-shaped hole 16. The upper and lower ends of the waist-shaped hole 16 are respectively the first positioning point for limiting the first hook piece 31 or the second hook piece 32 from being opened too much and the second positioning point for limiting the first hook piece 31 or the second hook piece 32 from being closed too much.

[0049] Further, the driving assembly further comprises at least one driving rod 62, the driving rod 62 being movable along the length direction of the waist-shaped hole 16, one end of each driving rod 62 being connected with the connecting rod 61, and the other end being connected with the traction rope, so as to drive the connecting rod 61 to move in the direction away from the gap 11 by pulling the traction rope.

[0050] Further, the first end of the first connecting piece 11 and the first end of the second connecting piece 12 are connected through the limiting posts 17. Specifically, the limiting posts 17 are two, which are arranged on the two sides of the gap 15 respectively, the movable ends 311 of the first hook piece 31 and the second hook piece 32 are both provided with limiting protrusions 315, and the two limiting protrusions 315 are respectively abutted against the outer sides of the two limiting posts 17. In this embodiment, under the action of the torsion force of the double torsion spring 33, the two limiting protrusions 314 are respectively abutted against the outer sides of the two blocking posts 5, so that the first hook piece 31 and the second hook piece 32 are limited to continue to move in the direction of approaching each other, the closed state of the utility model is realized, and it is ensured that the first hook piece 31 and the second hook piece 32 will not shake in the closed state.
