DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, the technical solutions of the embodiments of this application will be clearly and completely described in combination with the drawings of the embodiments of this application, and the described embodiments are not all the embodiments, but only some of the embodiments of this application. Based on the embodiments of this application, on the premise that a person skilled in the art does not make any inventive effort, all other embodiments obtained fall within the protection scope of this application.

[0020] In order to make those skilled in the art better understand the solutions of the present application, the present application will be further described in detail hereinafter in combination with drawings and specific embodiments.

[0021] This application provides a double-sided insertion member, which includes an insert pin 20 and a box pin 30. The double slider 10 is attached to the box pin 30, and after the double slider 10 has fully moved, the insert pin 20 is inserted into the cavity of the double slider 10. A box pin side wing seat 40 is provided on the side of the tape that is located at the box pin 30, and the box pin side wing seat 40 is provided on the outside of the box pin 30, and a box pin side wing passage is provided between them, which provides a guide passage for the insert pin 20 for insertion, so that the insert pin 20 can be accurately inserted into the guide passage. A position limiting portion 501 is provided in the box pin side wing passage, which limits the lateral position of the slider that has fully moved, preventing the two sliders from swinging left and right.

[0022] The upper slider and the lower slider are mounted on the box pin 30 and the box pin side wing base 40 through the box pin side wing passage. In the traditional box pin device, the slider swings with the swaying of the garment, which is prone to misalignment, and the two slider cavities cannot be aligned, so that the insert pin 20 cannot be inserted into the two slider cavities quickly and effectively.

[0023] To address this problem, when the upper slider of the present application passes through the side wing base, the box pin side wing passage acts to guide the movement of the slider, so that the insert pin 20 can be more easily inserted into the cavities of the two sliders, and the position limiting portion 501 prevents the sliders from shifting and assists in fixing the sliders, ensuring that the two sliders do not swing left and right or become biased on the insert pin 20.

[0024] In the double-sided insertion member provided by the present application, the interlocking of the two sliders is stable and unlikely to cause misalignment, the operation is simple, and there is no need for separate observation and positioning; it is sufficient to pull the two sliders to the end, the manufacturing process is simple, and there is little change in the overall manufacturing flow.

[0025] The box pin side wing passage is a bottomed passage. The bottom is pressed and fixed to the cloth tape by a press die. The box pin side wing base 40 and the box pin 30 are connected by the bottom, that is, a passage is formed between the box pin side wing base 40, the box pin 30 and the bottom, thereby forming a base passage.

[0026] By providing a certain thickness to the bottom of the passage, the meshing active space between the seam of the slider and the side wing base passage is filled, the friction resistance of the slider is increased, and the friction force of the forward movement of the double slider 10 is increased, so that the fully closed slider is prevented from being displaced along the front-rear direction, and the stability of the forward movement of the slider is further ensured.

[0027] Referring to Fig. 1, Fig. 1 is a schematic diagram of a double-opening inserter provided in the first embodiment of the present application. In the drawing, the box bar side wing passage is generally arranged in the middle of the box bar side wing base 40, and is provided with a position limiting part 501, which is tapered, and plays the role of guiding during movement and limiting the lateral position after sufficient movement, and can combine the friction force between the bottom of the passage and the slider to realize effective position limiting for the slider.

[0028] 2 is a schematic diagram of a double-opening inserter provided in a second embodiment of the present application. In the drawing, a first guide portion 502 is provided at the entry end of the box pin side wing passage located on the slider, and the first guide portion 502 tapers gradually along the entry direction of the slider and smoothly transitions to the position limiting portion 501 at the tip. The first guide portion 502 makes it easier to guide the slider to enter, and the position limiting portion 501 holds and limits the position of the fully closed double slider 10, making the slider pull smoother and more efficient and convenient.

[0029] Referring to Figures 3 and 4, Figure 3 is a structural schematic diagram of a double-opening insertion member provided in the third specific embodiment of the present application, and Figure 4 is a structural schematic diagram when the insert pin, box pin and double slider of Figure 3 are closed.

[0030] 3 and 4, the moving end of the box pin side wing passage located on the slider is provided with a second guide part 503 to guide the slider to enter, along the closing direction, the second guide part 503 is provided at the tip of the first guide part 502, and gradually widens along the slider's entering direction, and the position limiting part 501 is taken up between the first guide part 502 and the second guide part 503, tapered, and the three transition smoothly. For the two sliders fully closed, please refer to FIG. 4.

[0031] In this embodiment, the second guide portion 503 is added based on the first guide portion 502, and the second guide portion 503 guides the slider so that it is pulled in or pulled out. The width of the second guide portion 503 is greater than the width of the intermediate position limiting portion 501, and the first guide portion 502 and the second guide portion 503 exert a guiding effect to facilitate the entry of the two sliders. The position limiting portion 501 prevents the slider from shifting or swinging, exerts a locking and position limiting effect, and prevents collision with the box pin side wing base 40. Furthermore, the position limiting portion 501 performs a locking and position limiting function on the double slider 10 that is fully closed, preventing the slider from swinging.

[0032] Please refer to FIG. 5, which is a structural schematic diagram of a double-sided insert member provided in the fourth embodiment of the present application.

[0033] In the drawing, a first guide portion 502, a position limiting portion 501 and a second guide portion 503 are sequentially provided on the box pin side wing base 40 along the slider insertion direction, and the tip of the box pin 30 and the tip of the second guide portion 503 are respectively extended forward and connected to form a guide groove 504 for guiding the slider to enter quickly, and a stop is formed at the end to prevent the slider from falling off due to excessive force.

[0034] In order to ensure safety during use, the box pin 30 and the extension of the second guide portion 503 are formed in a circular arc structure without corners, thereby preventing injury to people.

[0035] In addition, in order to ensure good engagement between the guide groove 504 and the outer arc angle of the tip of the slider, the guide groove 504 is set in a U-shaped groove, and the U-shaped groove is matched with the tip arc angle of the slider, and its size is matched with the tip arc angle of the slider, so as to cover the slider and realize the position restriction of the slider. Here, the guide groove 504 is not limited to a U-shaped structure, and the specific structure of the guide groove 504 can be set according to actual needs, and is not limited in this specification.

[0036] The box bar side wing base 40, the bottom and the box bar 30 are preferably molded as a single piece, which is convenient to process and ensures strength.
