Description

Fastener device

【Technical field】

The present invention relates to buckles, and in particular to a buckle device that is easy to operate and can prevent children from opening it accidentally.

【Background technique】

Some parts of children's products such as strollers, child safety seats, and infant carriers usually need to be connected or maintained in a certain state through buckles. For example, infant carriers need to be connected and loosened, and they can be connected through Clamps are used to achieve this variable state connection. Normally, most of the buckles are plug-in safety buckles. This plug-in safety buckle requires the user to use both hands to align the matching male buckle and the female buckle for locking to achieve a safe connection. However, in reality, users often need to hold the child with one hand and operate the safety buckle with the other. Therefore, this plug-in safety buckle is more inconvenient to operate and cannot meet the needs of various scenarios. Therefore, buckles are gradually used to solve this problem.

A buckle is a buckle that is locked through magnetic attraction. It usually includes a buckle base and a lock, with magnets inside. When the two are close to each other, the position of the buckle can be adjusted under the action of magnetic attraction. Guide and bring the two together quickly. Since this kind of buckle is guided and attracted by magnetic force, it does not require the user to align it, and the user can operate it with one hand, so it is more convenient and convenient to use. Although this kind of buckle utilizes the guiding effect of magnetic force when locking to achieve positioning and locking between the buckles, the attraction between the magnets also requires resistance to the magnetic force when unlocking.

Existing buckles have various unlocking methods, such as pressing and lifting to unlock. When unlocking, first press and hold the unlocking piece to unlock the lock, and then lift one side of the lock to cause the magnet to open. Separate one end, weaken the attraction between the magnets, and then separate the entire lock. This kind of buckle needs to be pressed hard when unlocking. It either requires both hands to unlock, or it will exert pressing force on the passenger. Moreover, it needs to be lifted up to unlock. When lifting up, it needs to overcome the magnetic force, so it requires a large amount of force. It requires a lot of force to unlock, so the actual operation is inconvenient and laborious.

Another conventional unlocking method is to dislocate the magnet by sliding and then separate the lock. On the one hand, this buckle needs to provide space for the magnet to dislocate, so it is larger in size and its aesthetics needs to be improved; on the other hand, it needs to provide space for the magnet to dislocate. In terms of unlocking, the most familiar method in daily life is the push-to-unlock method, and the operation method of dislocating the magnets by sliding does not conform to the daily usage habits of the public. For first-time users, it is difficult to know how to unlock. Therefore, in There may be safety risks in some scenarios.

In order to solve the above problems, the applicant developed a magnetic buckle that presses in two directions to space a certain distance between the magnets to weaken the magnetic attraction, thereby facilitating unlocking. Its patent application number is 2019108246002. This structure is simple to operate, but it has been found in practice that it is easy to be accidentally unlocked by children's misoperation. The main reason is that when pressed in both directions, the lock hole will directly expand and the lock tongue can be moved out of the lock hole. , therefore, as long as the child presses in both directions, it is possible to unlock; even if the child is not strong, as long as he presses, it may cause unlocking, thus posing a safety hazard of accidental unlocking.

【Detailed ways】

The following examples further explain and supplement the present invention and do not constitute any limitation to the present invention.

As shown in FIGS. 1 to 21 , the buckle device of the present invention includes a male buckle 10 , a female buckle 20 , a locking component 30 and an elastic release component 40 . Among them, the locking part 30 and the elastic releasing part 40 are provided on the female buckle 20 .

As shown in Figures 2, 3, 9 and 10, the male buckle 10 is provided with a lock tongue 12.

As shown in Figures 2, 3, 9, and 10, the female buckle 20 is provided with a lock hole 221, and the lock hole 221 can be inserted into the lock tongue 12 of the male buckle 10.

As shown in Figures 2, 3, 9, and 10, the locking member 30 is movably installed in the female buckle 20, and is used to cooperate with the lock tongue 12 of the male buckle 10 to maintain the male buckle 10 in the female buckle. 20, thereby realizing the locking connection between the male buckle 10 and the female buckle 20. In addition, the locking member 30 can move along the actuation direction, so that the male buckle 10 and the female buckle 20 are disengaged, thereby realizing the separation of the male buckle 10 and the female buckle 20 .

As shown in Figures 2, 3, 9, and 10, the elastic release part 40 is movably installed in the female buckle 20, and includes a release operating part 43, an elastic part 44, a shoveling part 41 and a locking mechanism. Moving part 42. Among them, the lock-release operation part 43 is used to perform a lock-release operation, such as pressing. The elastic part 44 can act on the scooping out part 41, and the scooping out part 41 can move between the parts where the lock tongue 12 and the female buckle 20 are combined, thereby scooping out the lock tongue 12 and the female buckle 20. Opening facilitates the male buckle 10 to escape from the female buckle 20 , and the locking actuating part 42 can actuate the locking component 30 .

Among them, as shown in FIGS. 2 , 4 , 9 and 11 , the moving direction of the unlock operating part 43 is referred to as the unlock direction A for short.

The moving direction of the latch 30 is referred to as the actuation direction B.

The direction in which the lock tongue 12 moves out of the lock hole 221 is referred to as the tripping direction C.

As shown in Figures 2 and 9, the unlocking direction A and the actuation direction B are perpendicular to the tripping direction C. The unlocking direction A and the actuation direction B may be parallel (as shown in Figure 2) or perpendicular (as shown in Figure 9).

As shown in FIGS. 2 and 9 , when the release operation part 43 is moved along the release direction A to perform the lock release operation, the elastic part 44 is squeezed to accumulate force; the shoveling part 41 Then, under the action of the elastic part 44, the lock tongue 12 has a tendency to move out of the lock hole 221; at this time, because the lock tongue 12 is engaged with the locking member 30, the lock tongue 12 cannot come off along the lock hole 221. When the buckle is moved out in the direction C, the scooping out portion 41 only exerts a corresponding force on the lock tongue 12 . Only when the locking member 30 is disengaged from the lock tongue 12 , the force exerted by the shoveling portion 41 on the lock tongue 12 can cause the lock tongue 12 to move out of the lock hole 221 .

When the unlocking operating part 43 continues to move in the unlocking direction A, the locking actuating part 42 can activate the locking part 30 to disengage the locking part 30 from the lock tongue 12 When engaged, the shoveling portion 41 can drive the lock tongue 12 to move out of the lock hole 221 , thereby completing the unlocking and separation of the male buckle 10 and the female buckle 20 .

In this way, the safety of the buckle device can be ensured and the lock can be prevented from being unlocked by accidental contact: when the release operating part 43 is pressed but not to a sufficient extent, the locking part 30 cannot be disengaged from the lock tongue 12, and the male buckle 10 and the lock tongue 12 cannot be disengaged. The female buckle 20 still maintains the locked state, and the scooping out portion 41 only has a tendency to drive the lock tongue 12 out of the lock hole 221 , and when the force of the scooping out portion 41 acts on the lock tongue 12 , the lock tongue 12 can also be pressed down to increase the force for the latch member 30 to withdraw from the lock tongue 12, thereby increasing the opening force required for unlocking and preventing children from pressing or accidentally touching the lock tongue to easily unlock the lock tongue. Only when the force is continued and the force reaches a certain level, the lock actuating part 42 will activate the locking part 30 so that the locking part 30 and the lock tongue 12 are disengaged and the male buckle 10 and the female buckle 20 can be released. Lock separation. In this way, accidental touching of the lock-releasing operating part 43 or a child pressing the lock-releasing operating part 43 will not cause the male buckle 10 and the female buckle 20 to trip, thereby ensuring the safety of the buckle device.

Further, as shown in FIGS. 4 and 11 , in order to cause the scooped-out portion 41 to have a corresponding effect on the lock tongue 12 , a first extrusion slope 411 is provided on the scooped-out portion 41 . The normal vector of the first extrusion slope 411 has a first component vector and a second component vector that are perpendicular to each other. The first component vector is parallel to the unlocking direction A, and the second component vector is parallel to the tripping direction C, that is, parallel to the direction in which the male buckle 10 moves out of the female buckle 20 . Correspondingly, the end of the lock tongue 12 is provided with a fourth extrusion bevel 122 that can fit with the first extrusion bevel 411 . In this way, when the shoveling portion 41 advances in the unlocking direction A, the first pressing slope 411 can gradually exert a force on the lock tongue 12 to move it out of the female buckle 20 .

Further, as shown in FIG. 4 , a first magnetic component 11 can be provided in the lock tongue 12 , and a second magnetic component 23 can be provided in the female buckle 20 at a position corresponding to the lock hole 221 . The first magnetic component 11 and the second magnetic component 23 attract each other to facilitate the lock tongue 12 to be quickly aligned and inserted into the lock hole 221 . During the unlocking process, when the scooping out portion 41 acts on the lock tongue 12, the scooping out portion 41 is located between the interacting parts of the first magnetic component 11 and the second magnetic component 23. In this way, During the unlocking process, the shovel-out portion 41 can separate the parts of the male buckle 10 and the female buckle 20 that are combined together due to the mutual attraction of the first magnetic component 11 and the second magnetic component 23, thereby reducing the number of the first magnetic component 11 and the second magnetic component 23. The attraction between the magnetic parts 23 facilitates the removal of the male buckle 10 from the female buckle 20 .

Further, as shown in FIGS. 5 and 12 , in some embodiments, the elastic part 44 includes a fourth elastic part 441 , one end of the fourth elastic part 441 is connected to the shoveling part 41 , and the The other end of the fourth elastic part 441 is connected to the release operating part 43 .

Further, as shown in FIGS. 5 and 12 , the shoveling part 41 is movably provided on the unlocking operating part 43 and can move along the unlocking direction A. The fourth elastic part 441 is provided in the release operating part 43 .

As shown in FIG. 4 , when the unlocking operation part 43 is moved in the unlocking direction A, the shoveling part When the end of 41 moves to the position where the lock tongue 12 and the female buckle 20 are combined, it cannot move further. At this time, when the unlocking operating part 43 continues to move in the unlocking direction A, the fourth elastic part 441 will be compressed. The fourth elastic part 441 is caused to accumulate force. When the fourth elastic portion 441 is compressed, the shoveling portion 41 tends to drive the lock tongue 12 to move out of the lock hole 221 . When the lock tongue 12 is disengaged from the locking member 30 , the fourth elastic part 441 and the scooping out part 41 lose the resistance of the lock tongue 12 and move forward, so that the scoop out part 41 pushes the lock tongue 12 out of the lock hole. Extruded in 221.

Further, as shown in FIG. 5 , a restraining groove 433 is provided on the release operating part 43 . The restraining groove 433 is provided on an end of the release operating portion 43 opposite to the pressing portion. One end of the shoveling portion 41 is located in the restraining groove 433 , and one end extends outside the restraining groove 433 . The shoveling part 41 can move in the unlocking direction A relative to the unlocking operating part 43 , but cannot escape from the restraining groove 433 in the unlocking direction A. The fourth elastic part 441 is disposed in the restraining groove 433, and its installation direction moves in the unlocking direction A. One end of the fourth elastic portion 441 is in contact with the scooping out portion 41 , and the other end is in contact with the inner wall of the restriction groove 433 .

The first elastic part 444 and the second elastic part 445 can be arranged in a curved strip shape, so that they can deform and have elasticity when they are stressed. The shoveling part 41 is fixed on the first elastic part 444 , and the lock actuating part 42 is fixed on the second elastic part 445 .

Further, as shown in FIGS. 19 and 21 , the stroke distance from the shoveling part 41 to the lock tongue 12 is smaller than the stroke distance from the latch actuating part 42 to the latch 30 . In this way, when When the unlocking operating part 43 is moved in the unlocking direction and the first elastic part 444 and the second elastic part 445 are deformed, the shoveling part 41 moves to the target position before the latch actuating part 42, so that The shoveling part 41 first acts on the lock tongue 12 - driving the lock tongue 12 to move inwards from the lock hole 221 Then the locking actuating part 42 will act on the locking part 30 - actuating the locking part 30 to disengage the locking part 30 and the locking tongue 12. In this way, when the locking part 30 and the locking tongue 12 When disengaged, the first elastic part 444 and the shoveling part 41 will move forward when they lose the resistance of the lock tongue 12 , so that the shoveling part 41 squeezes the lock tongue 12 out of the lock hole 221 .

Furthermore, as shown in FIGS. 19 and 21 , in order to facilitate the operation of the unlocking operation part 43 to cause the elastic part 44 to elastically deform, the elastic part 44 further includes a third elastic part 446 . In some embodiments, as shown in FIG. 19 , both ends of the third elastic part 446 are respectively connected to the combination parts of the first elastic part 444 and the second elastic part 445 , so that the release operating part 43. The third elastic part 446 forms a ring structure. In some embodiments, as shown in FIG. 21 , one end of the third elastic part 446 is connected to the combination of the first elastic part 444 and the second elastic part 445 , and the other end is in contact with the female buckle 20 . When the release operating part 43 is operated, the first elastic part 444 , the second elastic part 445 , and the third elastic part 446 can all be elastically deformed due to force, thereby driving the scooping part 41 and the clamping part 41 .
