Technical field

The invention relates to the technical field of daily necessities, in particular to an anti-collision slider and an anti-collision zipper provided with the anti-collision slider.

Background technique

A zipper is a connection piece that relies on continuous arrangement of elements to merge or separate items, and is generally used in clothing, bags, tents, and the like.

In the prior art, a zipper is composed of a chain belt, a slider, an upper and lower stop (front and rear code) or a locking member. Generally, a zipper has two pieces of chain straps, each of which has a row of fastener elements, and the two rows of fastener elements are staggered and meshed with each other when being assembled. When in use, pull the pull body forward with the help of the pull force. Then, the two sides of the fastener elements can be clamped and squeezed by the locking holes on the rear side of the pull body, so that the fastener elements on both sides can be engaged and locked. At this time, by pulling the pull force to pull the pull body to slide backward, the element on both sides is separated by the base core located at the front end of the pull body, so that the elements on both sides can be disengaged from each other.

Currently on the market, the underside (ie, the back side) of most sliders is basically shaped as shown in FIG. 1. However, when used on clothing, in many sports, when the athlete is hit by the opponent ’s body or the ball heavily on the slider, the lower bottom plate of the slider of the structure will directly abut the physical body of the athlete's corresponding position. It is very painful to use it on the corresponding bone points, and the bottom plate of the slider is a plate-like structure, and the material is mostly metal alloy, which not only is not lightweight enough, but also easily hurts the user.

Therefore, how to make the slider light in shape, and how to avoid or reduce the impact of the slider on the pain, are technical problems that need to be solved by those skilled in the art.

Summary of the invention

In view of this, the object of the present invention is to provide an anti-collision slider and an anti-collision zipper provided with the anti-collision slider, which are lightweight in shape and are beneficial to reduce or even avoid the pain of the impact of the slider.

To achieve the above objective, the present invention provides the following technical solutions:

An anti-collision slider includes a pull body, and the pull body includes:

Foundation board

Two side walls, which are respectively located on both sides of the base plate, are used for squeezing the teeth on the chain belt when sliding forward;

A base core, which is located in the middle of the inside of the base plate and is used to separate the two side chain elements when sliding backward;

The middle bottom plate is fixedly connected to the end of the base core opposite to the base plate, and protrudes from both sides of the base core;

Two side bottom plates are respectively located at two ends of the side walls opposite to the base plate, and protrude from the inner surface of the side walls, and the side bottom plates on both sides and the middle plate A gap is left between the middle bottom plates for passing through the chain belt.

Preferably, in the anti-collision slider, the side bottom plate and the lower side surface of the middle bottom plate are located on the same plane.

Preferably, in the anti-collision slider, the length of the side bottom plate in the sliding direction is shorter than the length of the base plate in the sliding direction.

Preferably, in the anti-collision slider, the length of the middle bottom plate in the sliding direction is shorter than the length of the side bottom plate in the sliding direction.

Preferably, in the anti-collision slider, the front end of the base core is an arc edge, one end of the arc edge is connected to the front end of the base plate, and the other end is connected to the intermediate bottom plate.

Preferably, the above-mentioned anti-collision slider further includes a pull tab whose front end is hinged on the upper side of the base plate, wherein:

A mounting groove is provided on the upper side of the base plate, and the pull tab is hinged in the mounting groove;

And / or, two sides of the front end of the pull tab are provided with inner grooves for installing an elastic member, and the elastic member is used to provide an automatic restoring force for the pull tab;

And / or, a side of a rear end of the pull tab opposite to the base plate is provided with a locking tooth for abutting against the fastener element;

And / or, a side of the rear end of the pull tab opposite to the base plate is provided with a concave concave surface.

Preferably, in the anti-collision slider, the thickness of the pull tab is equal to the depth of the mounting groove.

Preferably, in the anti-collision slider, the length of the mounting groove in the sliding direction is shorter than the length of the base plate in the sliding direction.

Preferably, in the anti-collision slider, the upper side of the front end of the mounting groove is an arc-shaped inclined surface.

An anti-collision zipper includes a slider and a chain strap. The slider is an anti-collision slider as described above.

As can be seen from the above technical solution, the crash-proof slider provided by the present invention and the zipper provided with the crash-proof slider are mainly innovating the slider body structure without affecting the basic function of the slider engaging the zipper. The design, the lower bottom plate (ie the back) of the slider is composed of two side bottom plates and the middle bottom plate, and its shape is lightweight. In addition, during use, if the anti-collision slider is impacted, the lower bottom plate is the point of impact for hitting the human body, and because of its relatively small area, and the two side bottom plates are blocked by the chain belt and are not directly against the human body. Contact, only the middle bottom plate may be in contact with the human body in the clothes, which is beneficial to reduce or even avoid the impact pain caused by the slider, and can avoid the situation that the clothing slider will cause injuries to the user when the slider is in motion.
