Description

Technical Field

[0001] The present invention relates to the technical field of zipper pull heads, in particular to a pull head with a magnetic attraction function. Background Art

[0002] A zipper pull allows users to easily open and close the zipper. Its main components include a pull ring, a connecting rod, a guide groove, and a fixing mechanism. The pull ring is typically made of metal, plastic, or rubber and comes in a variety of shapes for easy grip. The connecting rod acts as the main mechanism, driving the teeth to ensure smooth closing and opening. The guide groove guides the teeth' correct movement and prevents them from slipping. Some designs also feature a locking mechanism to secure the zipper in place and prevent accidental slippage. When using the zipper head, the user holds the pull ring and pulls it hard to open or close the zipper, which is simple and convenient to operate. For example, an anti-theft zipper disclosed in application publication number CN115104819A includes a first zipper strip, a second zipper strip, a zipper head base and a pulling piece. The first zipper strip and the second zipper strip are respectively installed on the clothing or bag body, and the two are arranged in cooperation. The zipper head base is detachably connected to the chain teeth of the first zipper strip and the second zipper strip, and the zipper head base is detachably connected to the zipper head base, and the zipper head base is driven to move by the pulling piece, so as to pull the first zipper strip and the second zipper strip up or down, and the pulling piece and the zipper head base are connected together by different detachable methods (such as threaded connection, snap connection method, bonding method, magnetic attraction method, sleeve connection, etc.). It has a simple structure and low cost, and the pull piece can be easily and quickly installed on the zipper head base. However, when the above technical solution is applied to zippers of bag structures such as backpacks, handbags and luggage, the two zipper heads are relatively and symmetrically installed at both ends of the zipper. When the two zipper heads are close and in contact, the zipper is in a closed state, but the two zipper heads are only in contact with each other, which can meet basic closing requirements under static conditions. In a dynamic environment, especially when the bag is shaken, hit or pulled, the contact surface is easily separated due to vibration, that is, the external force between the two zipper heads exceeds a certain threshold, and the zipper heads will separate due to uneven force or sliding, causing the zipper to open. At this time, the items in the bag are easy to fall out of the zipper that is not fully closed or be stolen. Secondly, the user experience is reduced, and frequent zipper separation requires readjustment or repair, which brings inconvenience and trouble. Summary of the Invention

[0003] The purpose of the present invention is to provide a slider with a magnetic suction function. When the left slider and the right slider installed at both ends of the zipper are close to each other, the first curved arch nose of the left slider and the second curved arch nose of the right slider are quickly magnetically combined through a magnetic sheet.

[0005] Preferably, the surface of the planar portion is provided with a 1 mm deep rectangular groove for embedding the magnetic sheet, the magnetic sheet has a thickness of 1 mm and a rectangular cross-section.

[0006] Preferably, the depth of the docking hole in the plane portion is 0.5 mm to 1 mm.

[0007] Preferably, the elastic connecting pin includes a hollow pin sleeve fixed on one side of the interior of the planar portion and a T-shaped pin elastically installed inside the hollow pin sleeve. Both ends of the T-shaped pin pass through the outside of the planar portion and the hollow pin sleeve. After the first curved arch nose and the second curved arch nose complete magnetic attraction, the T-shaped pin is plugged into the docking hole on the second curved arch nose.

[0008] Preferably, an annular inner edge is integrally formed at one end of the hollow pin sleeve, and a coil spring coaxial with the T-pin is installed on the outer wall of one side of the annular inner edge, and one end of the coil spring is in contact with a stepped surface on one side of the T-pin.

[0009] Preferably, one end of the T-shaped pin is provided with a round head, and the other end of the T-shaped pin is provided with a through hole, and an R-shaped pin is installed inside the through hole.

[0010] Preferably, in the initial state of the coil spring, the distance between the end of the T-shaped pin on one side of the round head and the flat portion is 0.5 mm to 1 mm.

[0011] Preferably, the bidirectional snap-fastener mechanism includes a hollow seat fixed inside the rectangular concave cavity of the left slider, a swing fastener hingedly mounted on the top and bottom walls of the hollow seat, and two limit springs mounted on the top wall of the swing fastener, and the top end of the limit spring abuts against the inner wall surface of one side of the rectangular concave cavity.

[0012] Preferably, a protrusion is provided at one end of the docking joint close to the protrusion, a docking cavity for inserting the protrusion is provided inside the hollow seat, and sinking grooves are provided at the top and bottom ends of the docking joint for the end of the swing buckle to be embedded in the sinking grooves.

[0013] Preferably, the top wall and the bottom wall of the rectangular cavity of the left slider are both provided with circular recessed holes, and the circular recessed holes are for the end of the limit spring to enter.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the slider with a magnetic attraction function is provided with a left slider, a first curved arch nose, a two-way spring buckle mechanism, a right slider, a second curved arch nose, a magnetic sheet, an elastic connecting pin and other structures that cooperate with each other, thereby greatly reducing the probability of connection failure or separation caused by external force, vibration or improper operation, and even if a certain layer of locking mechanism fails under special circumstances, the other mechanisms can still maintain the integrity of the connection, thereby ensuring the stability of the zipper in a dynamic environment; when the left slider and the right slider installed at both ends of the zipper are close to each other, the first curved arch nose of the left slider and the second curved arch nose of the right slider are quickly magnetically combined by the magnetic sheet, and during the combination process, the elastic connecting pin and the docking hole are docked to form a mechanical lock, and the left slider and the right slider are then locked again by the two-way spring buckle mechanism and the docking joint to cope with the risk of slider separation under the action of external force in a dynamic environment; Among them, the introduction of the magnetic sheet greatly improves the convenience and accuracy of the slider connection. When the first curved arch nose of the left slider and the second curved arch nose of the right slider are close to each other, the magnetic sheet quickly attracts and combines the two through magnetic force. This process realizes a fast, silent and high-alignment connection, avoiding the deviation or docking difficulty that may occur in traditional mechanical connections. The magnetic effect ensures that the sliders can automatically align when they are close, reducing the difficulty of user operation and improving the connection efficiency. In addition, the magnetic adsorption also has a certain buffering effect, which slows down the instantaneous impact when external force acts, reduces the stress concentration at the connection part, and thus prolongs the service life of the slider. Secondly, after the magnetic combination, the elasticity on the flat surface of the left and right sliders The elastic connecting pin is tightly combined with the docking hole through elastic deformation to form a stable mechanical lock. This mechanical locking mechanism ensures that even if the magnetic attraction is temporarily broken under the action of external force, the mechanical lock of the elastic pin can still provide a second layer of protection to prevent the slider from accidentally separating. Finally, the two-way snap mechanism and the secondary locking of the docking joint further consolidate the stability of the connection. On the basis of the magnetic attraction and elastic pin mechanism, the two-way snap mechanism provides an active locking function to ensure that the left and right sliders will not loosen or fall off due to vibration, pulling or vibration after connection. That is, it can automatically lock when subjected to external force and has good adaptability, thereby ensuring that the sliders at both ends are tightly aligned when connected to avoid loosening or slipping due to deviation or external force.

[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] Embodiment 1, by Figures 1 to 7The present invention includes a left slider 1, a right slider 2 arranged on one side of the left slider 1, and a first curved arch nose 4 and a second curved arch nose 5 integrally formed on the top of the left slider 1 and the right slider 2. A plane portion 6 is provided on the outer wall of the side close to the first curved arch nose 4 and the second curved arch nose 5. A magnetic sheet 7 is inlaid on one side of the surface of the plane portion 6, and elastic connecting pins 9 are respectively installed inside the plane portions 6 on both sides of the magnetic sheet 7 and docking holes 8 are opened. The first curved arch nose 4 and the second curved arch nose 5 are magnetically attracted by the magnetic sheet 7 and locked by the docking holes 8 and the elastic connecting pin 9. The first curved arch nose 4 and the second curved arch nose 5 are designed to be easy to pinch by hand, and cooperate with the internal locking structure to achieve smoothness and tension when pulling, and the two are mutually embedded through the plane portion 6; The user pinches the first curved nose 4 of the left slider 1 with the thumb and index finger of the left hand, and pinches the right slider 2 with the same gesture with the right hand. At this time, the left slider 1 and the right slider 2 are in a relative state on the zipper. When the two sliders are moved to a distance of two to four centimeters, the magnetic sheets 7 on the two nose planes 6 begin to generate an effective magnetic field; A rectangular cavity 3 is provided at the opposite ends of the left slider 1 and the right slider 2. A two-way snap mechanism 10 is installed inside the rectangular cavity 3 of the left slider 1, and a docking joint 11 is installed inside the rectangular cavity 3 of the right slider 2. The docking joint 11 and the two-way snap mechanism 10 complete the plug-in connection when the ends of the left slider 1 and the right slider 2 touch each other; The surface of the planar portion 6 is provided with a 1mm deep rectangular groove for embedding the magnetic sheet 7. The thickness of the magnetic sheet 7 is 1mm and the cross-sectional shape is rectangular. When the left slider 1 and the right slider 2 approach each other and complete the magnetic attraction action, the elastic connecting pin 9 on the first curved arch nose 4 will automatically enter the docking hole 8 of the second curved arch nose 5. Similarly, the elastic connecting pin 9 on the second curved arch nose 5 also synchronously enters the docking hole 8 of the first curved arch nose 4, so as to prevent the left slider 1 and the right slider 2 from accidentally opening or loosening during the pulling process, so that the slider is suitable for occasions that need to be frequently pulled and closed or withstand large pulling forces, and makes the zipper safer in use.

[0019] Example 2, based on Example 1, Figure 8 and Figure 9 It is given that the depth of the docking hole 8 in the plane portion 6 is 0.5 mm to 1 mm, and the elastic connecting pin 9 includes a hollow pin sleeve 901 fixed to one side of the interior of the plane portion 6 and a T-shaped pin 903 elastically installed inside the hollow pin sleeve 901. Both ends of the T-shaped pin 903 pass through the plane portion 6 and the outside of the hollow pin sleeve 901. After the first curved arch nose 4 and the second curved arch nose 5 complete the magnetic attraction, the T-shaped pin 903 is plugged into the docking hole 8 on the second curved arch nose 5; An annular inner edge 902 is integrally formed at one end of the hollow pin sleeve 901. A coil spring 904 is mounted on one outer wall of the annular inner edge 902 and is coaxial with the T-shaped pin 903. One end of the coil spring 904 contacts a stepped surface on one side of the T-shaped pin 903. At the moment when the two magnetic attraction sheets 7 are magnetically attracted, the T-shaped pin 903 on the first curved nose 4 will encounter the docking hole 8 on the second curved nose 5. At this time, since the flat portions 6 on the first curved nose 4 and the second curved nose 5 are in surface contact, the coil spring 904 will reset from the compressed state and push the T-shaped pin 903 toward the docking hole 8 until the T-shaped pin 903 enters the docking hole 8 to complete the connection. A round head 9031 is provided at one end of the T-shaped pin 903, and a through hole 9032 is provided at the other end of the T-shaped pin 903. An R-shaped latch 9033 is installed inside the through hole 9032. During the insertion of the T-shaped pin 903 and the docking hole 8, the R-shaped latch 9033 in the through hole 9032 is located on the other side of the flat portion 6 and is used to block the T-shaped pin 903 from moving forward, preventing the T-shaped pin 903 from being inserted too deeply, thereby preventing the left slider 1 and the right slider 2 from being unable to separate later; In the initial state of the coil spring 904, the distance between the end of the T-pin 903 on the side of the round head 9031 and the flat portion 6 is 0.5mm to 1mm. Since the round head 9031 is provided at the end of the T-pin 903, the left slider 1 and the right slider 2 can be easily separated under the action of the round head 9031. That is, when the left slider 1 and the right slider 2 are subjected to axial tension, the end of the T-pin 903 automatically exits the docking hole 8 through the round head 9031, thereby achieving the purpose of quickly separating the two sliders.

[0020] Example 3, based on Example 1, Figure 10 and Figure 11 The bidirectional snap mechanism 10 includes a hollow seat 1001 fixed inside the rectangular cavity 3 of the left slider 1, a swing buckle 1003 hingedly mounted on the top and bottom walls of the hollow seat 1001, and two limit springs 1004 mounted on the top wall of the swing buckle 1003. The top ends of the limit springs 1004 abut against the inner wall of one side of the rectangular cavity 3. The end of the docking joint 11 close to the raised portion 1101 is provided with a raised portion 1101, and the interior of the hollow seat 1001 is provided with a docking cavity 1002 for the raised portion 1101 to be inserted. The top and bottom ends of the docking joint 11 are both provided with a sinking groove 1102, and the sinking groove 1102 is for the end of the swing buckle 1003 to be embedded. The top wall and bottom wall of the rectangular cavity 3 of the left slider 1 are both provided with a circular concave hole, and the circular concave hole is for the end of the limit spring 1004 to enter. When the left slider 1 and the right slider 2 complete the magnetic attraction, the raised portion 11 at the end of the docking joint 11 is engaged. 01 will also enter the docking cavity 1002 of the hollow seat 1001. During the insertion of the hollow seat 1001 and the raised portion 1101, the swing buckle 1003 will encounter the sunken groove 1102. At this time, the limit spring 1004 is compressed and deformed and forces the swing buckle 1003 to always swing toward the central axis of the docking head 11, that is, the end of the swing buckle 1003 is always pressed in the sunken groove 1102. In this way, after the zipper is closed, the docking head 11 is locked in both the upper and lower directions, further preventing the slider from loosening due to vibration during movement. When the two-way snap mechanism 10 and the docking head 11 are separated, the end of the swing buckle 1003 will naturally be withdrawn from the sinking groove 1102 until the docking cavity 1002 and the protruding portion 1101 are separated; A fluorescent coating is sprayed on the outer peripheral surfaces of the first curved arch nose 4 of the left slider 1 and the second curved arch nose 5 of the right slider 2, so that the zipper head forms an autonomous light source system in a dark environment. Even in a dark environment, the user can quickly identify the position of the slider to avoid misoperation or difficulty in operation due to unclear vision. It is suitable for occasions where the device needs to be used at night or in low light conditions, such as outdoor sports, night travel, emergency equipment and other zipper opening and closing scenarios.

[0021] When using the embodiment of the present application, first ensure that all parts are intact, the magnetic sheet 7, the elastic connecting pin 9, the docking hole 8, the two-way snap mechanism 10, and the docking joint 11 are not damaged or deformed, and at the same time confirm that the left slider 1, the right slider 2, the first curved arch nose 4, the second curved arch nose 5 and the two-way snap mechanism 10 are clean and tidy, without any debris blocking them, so as to facilitate subsequent operations; the user pinches the first curved arch nose 4 of the left slider 1 with the thumb and index finger of the left hand, and pinches the right slider 2 with the same gesture with the right hand. At this time, the left slider 1 and the right slider 2 are in a relative state on the zipper, and the two sliders are moved to a distance of two to four inches. When the first curved arch nose 4 and the second curved arch nose 5 enter the range of action of the magnetic pole, an attractive force will be generated between the sliders, prompting them to enter the state of preparation for precise docking. At this time, the effect of magnetic attraction not only helps to quickly locate, but also reduces the difficulty of manual alignment. When the arch noses of the left slider 1 and the right slider 2 are gradually connected, the magnetic sheet 7 will attract the two together to form a preliminary connection. At this time, the staff can gently apply pressure to ensure that the first curved arch nose 4 and the second curved arch nose 5 enter the range of action of the magnetic pole. The left slider 1 and the right slider 2 are connected by the two-way snap-fastener mechanism 10 and the docking joint 11. The left slider 1 and the right slider 2 are connected by the two-way snap-fastener mechanism 10 and the docking joint 11. The left slider 1 and the right slider 2 are connected by the two-way snap-fastener mechanism 10 and the docking joint 11. After that, the user can gently pull the left slider 1 and the right slider 2, or apply torque alternately to the left and right sides to observe whether the slider joint produces relative rotation to verify the stability of the connection. Under normal conditions, no displacement should occur, indicating that the connection is successful and safe; when the user needs to release the connection between the left slider 1 and the right slider 2, he or she should also pinch the left slider 1 and the right slider 2 with his or her left and right hands, and apply pulling force in the two axial directions simultaneously to overcome the magnetic force of the magnetic sheet 7, the plugging resistance of the docking hole 8 and the elastic connecting pin 9, and the plugging force of the two-way snap buckle mechanism 10 and the docking joint 11, so as to achieve the purpose of opening the zipper.
