Description

Quick-release fastener

Technical Field

The utility model relates to a quick-release fastener.

Background

The bulletproof clothes are individual soldier protective armwear for protecting human trunk from being damaged by projectile or shrapnel, are mainly in the shape of vest, and have good protective effect on human chest and abdomen. The thickness of the bulletproof layer is determined according to different use objects with the optimal balance between the protection performance and the wearing comfort. The soldier wearing can obviously reduce the death rate and the negative injury rate of the battlefield.

Army and partial police often need to use the bulletproof clothes to execute dangerous tasks, and the bulletproof clothes are required to be removed in emergency situations when the tasks are executed, so that the bulletproof clothes are required to be rapidly removed in emergency situations, and emergency situations such as falling into water, withdrawing and the like are better coped with.

The prior bulletproof clothes are preliminarily formed in a manner of elastic installation and quick disassembly between a buckle and a buckle seat. However, the following problems still remain:

1. the existing buckle and the buckle seat are still in a pressing mode, and the connecting position of the buckle and the buckle seat is pressed when the buckle is detached, so that the buckle is detached, but the condition of locking frequently occurs;

2. the mode that adopts the stay cord traction to carry out the unblock and dismantle between current buckle and the knot seat has still been adopted, but the part that this kind of mode used is more, and the equipment is loaded down with trivial details, and the cost is higher to because the atress position that drives the buckle unblock is difficult to select, the fault rate is high.

In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

The present utility model will be described in further detail with reference to the accompanying drawings.

Example 1:

as shown in fig. 1, a quick release fastener includes a fastener seat 1 and a fastener 2 cooperatively connected with the fastener seat 1. One side of the buckle seat 1 is provided with a buckle 3 which is arranged oppositely. The buckle 3 may be made of rubber or other elastic materials. The tail ends of the buckles 3 are connected with the buckle seat 1, so that the two buckles 3 can swing in opposite directions at a short distance.

As shown in fig. 2, 3 and 4, a positioning groove 4 is provided between the buckle 3 and the buckle seat 1, and the positioning groove 4 is used for connecting the fastener 2, so that the fastener 2 and the buckle seat 1 are stably clamped. Wherein, buckle 3 is provided with chamfer 5 corresponding to one side of constant head tank 4 to reach the purpose of further locating fastener 2, prevent fastener 2 from deviate from.

A connecting seat 6 is connected between the two buckles 3 through a connecting piece. The connecting pivot 7 is positioned in the middle of the buckle 3 and used for improving the force of the pivot 7 when the buckle 3 swings in opposite directions, and meanwhile, the connecting stability between the connecting seat 6 and the buckle 3 can be ensured. If the fulcrum 7 is disposed close to the buckle seat 1, the buckle 3 is difficult to swing, and if the fulcrum 7 is disposed close to the head of the buckle 3, the swing amplitude is too large, so that the buckle 3 is easy to break. The connecting seat 6 is used for pulling the buckles 3, so that the buckles 3 swing in opposite directions, and the effect of separating and unlocking from the buckle 2 is achieved. The middle part of the connecting seat 6 is provided with a connecting groove 8. A traction block 9 is arranged in the connecting groove 8. The traction block 9 is connected with a traction rope 10. The traction rope 10 passes through the buckle seat 1. A sliding groove 11 is arranged in the buckle seat 1. The sliding groove 11 is correspondingly provided with a fixed block 12, and the traction rope 10 and the fixed block 12 are arranged in a sliding way, so that the moving direction of the traction rope 10 is limited.

When the unlocking operation is needed between the fastener 2 and the buckle seat 1, the traction rope 10 is pulled, so that the traction rope 10 drives the traction block 9 to move, the traction block 9 is matched with the connecting seat 6 to move, and the connecting seat 6 is driven to move towards the direction of the buckle seat 1. Under the drive of connecting seat 6 for thereby two buckles 3 that are connected with connecting seat 6 receive torsion and realize the swing in opposite directions of short distance, thereby make constant head tank 4 and fastener 2 separation, can pull out fastener 2 after the separation, realize the separation of fastener 2 and knot seat 1, reach the purpose of dismantling fastener 2 fast, be applicable to the application of body armor.

Preferably, two guide blocks 13 with inclined planes 14 matched with the connecting seat 6 are arranged on one side of the buckling seat 1 corresponding to the position of the connecting seat 6. A limit groove 15 is formed between the guide block 13 and the buckle seat 1. When the connecting seat 6 is pulled to be abutted on the inclined plane 14 of the guide block 13, the correction function can be realized on the connecting seat 6, so that the connecting seat 6 is guided into the limit groove 15 until the connecting seat 6 cannot move continuously to complete unlocking.

Example 2:

as shown in fig. 5 and 6, the difference from embodiment 1 is that the buckle seat 1 is provided with a chute 16 at one side of the positioning groove 4. A slide 17 is slidably arranged in the slide groove 16. The slide 17 is provided with a guide surface 18 on one side. A spring 19 is arranged between the sliding block 17 and the buckle seat 1. When the fastener 2 is snapped into the detent 4, the fastener 2 presses the slider 17 so that the slider 17 slides into the runner 16, at which time the spring 19 is compressed, thereby accumulating potential energy.

When the connecting seat 6 moves in the unlocking state, namely, when the connecting seat 6 enters the limit groove 15 and cannot move continuously, the spring 19 drives the sliding block 17 to move reversely, so that the fastener 2 is pushed outwards and leaves the region of the limit groove 15, and an automatic disengaging effect is realized.

The reason for the above-mentioned main arrangement is that, under normal circumstances, a soldier wearing bulletproof clothes or a special police may hold a weapon or other articles, and when the pulling rope 10 is pulled by one hand to unlock, if the fastener 2 is adhered to the fastening seat 1, the quick-release effect of the fastener will be affected, therefore, the slider 17 is further arranged, so that the slider 17 has a further elastic pushing effect on the fastener 2, thereby further reducing the difficulty of separating the fastener 2 from the fastening seat 1, and facilitating the use.

The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.
