Description

Technical Field

[0001] This utility model relates to the field of garment accessories technology, and more specifically, it relates to a novel nail-free button. Background Technology

[0002] Buttons are generally used to fasten clothes or trousers. They are small, ball-shaped or flat objects that are slipped onto buttonholes to fasten clothes, trousers, etc. Ordinary buttons are sewn onto clothing using thread.

[0003] For example, the authorized announcement number CN217592175U discloses a nail-free button, which achieves a detachable connection between the button and the button body by setting a movable locking hole and the threaded connection between the nail part of the button and the locking hole.

[0004] In the above method, threads are used to connect the tack to the button body. However, in actual use, the threaded connection is prone to wear due to friction from clothing or frequent disassembly, which can easily cause it to loosen and fall off. In addition, the rotation and locking requires two hands, resulting in a poor user experience. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of nail-free button that enhances the user experience.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A novel nail-free button includes a button body and a snap fastener, wherein the snap fastener end face is provided with an axially extending connecting rod. The outer circumferential wall of the connecting rod has continuous serrations evenly distributed along the circumference. The button body has a locking hole on its end face corresponding to the insertion path of the connecting rod, and the button body has a cylindrical fastening cavity that is coaxially connected to the locking hole. Two sets of elastic fastening components are arranged symmetrically along the radial direction inside the fastening cavity. Each elastic fastening component includes a U-shaped clamp, a fixed base, and a return spring. The open end of the U-shaped clamp slides against the inner wall of the fastening cavity through a guide rail structure. The free end of the U-shaped clamp extends towards the axis of the locking hole to form a triangular interlocking protrusion. The fixed base is fixed in the inner space of the two U-shaped clamping mechanisms. The two ends of the return spring are respectively connected to the side wall of the fixed base and the inner wall of the U-shaped clamping mechanism. The free end of the U-shaped clamping mechanism is kept in a state of being retracted towards the center under the pre-tightening force of the return spring. The button body has an adjustment channel that communicates with the fastening cavity along the radial direction on its side wall.

[0007] The present invention is further configured such that: an annular adjustment base is provided at the end of the locking hole, the adjustment base is fixedly connected to the wall of the fastening cavity, and its annular inner surface maintains a preset gap with the free end of the U-shaped clamping mechanism.

[0008] The present invention is further configured such that: a first magnetic sheet is embedded at the end of the connecting rod, and a second magnetic sheet is embedded at the corresponding position at the bottom of the locking hole, wherein the first magnetic sheet and the second magnetic sheet are arranged with opposite poles to form an axial magnetic attraction fit.

[0009] The present invention is further configured such that: the inner side of the U-shaped clamp is provided with a slot that matches the saw teeth of the connecting rod, and the inclination angle of the slot forms a complementary interlocking contact with the tooth surface of the saw teeth.

[0010] The present invention is further configured such that: a guide slot is provided on the outer surface of the button body, and an adjusting rod is detachably connected in the guide slot, wherein the effective working length of the adjusting rod is greater than the sum of the depth of the adjusting channel and the distance between the opening end of the U-shaped clamping mechanism.

[0011] Compared with the shortcomings of the prior art, the beneficial effects of this utility model are as follows: The connecting rod engages with the elastic fastening component inside the locking hole, achieving a secure fixation through the interlocking of the serrations and the slot. During installation, simply press to automatically lock, making it easy and time-saving to operate with one hand. The magnetic component allows the snap fastener and button body to automatically adhere and align, eliminating the need for visual calibration and making it particularly suitable for blind operation. The U-shaped clip, combined with the return spring, forms a bidirectional force structure, ensuring tensile strength in the locked state while allowing for easy separation when the adjustment rod is pressed. The disassembly process requires no tools and does not damage clothing. The combination of the adjustment channel and the detachable connecting rod makes maintenance more convenient, allowing for individual replacement of damaged parts, significantly reducing operating costs.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] Working principle: When in use, first align the connecting rod 3 of the snap fastener 2 with the locking hole 5 of the button body 1. The insertion angle is automatically corrected by the adsorption force of the first magnetic piece at the end. When the connecting rod 3 enters the locking hole 5, its surface serrations 4 contact the inclined surface of the inner groove 11 of the U-shaped clip 6. When the serrations 4 pass through the groove 11, the return spring 8 rebounds, causing the U-shaped clip 6 to tighten and engage. At this time, pulling the snap fastener 2 in the opposite direction will be blocked by the vertical surface of the serrations 4 and the groove 11, forming a firm lock. When disassembly is required, insert the matching adjusting rod from the side slot. The front end of the adjusting rod pushes against the opening end of the U-shaped clip 6, causing it to slide outward to expand the gap. After the groove 11 and the serrations 4 disengage, the snap fastener 2 can be easily pulled out.

[0017] like Figures 1 to 2 As shown, It includes a button body 1 and a snap fastener 2. The end face of the snap fastener 2 is provided with an axially extending connecting rod 3. The outer peripheral wall of the connecting rod 3 is evenly distributed with continuous serrations 4 in the circumferential direction, and is fixed by the serrations 4 engaging with the U-shaped clip 6.

[0018] The outer surface of the button body 1 is provided with a guide slot 12, and an adjusting rod is detachably connected inside the guide slot 12. The effective working length of the adjusting rod is greater than the sum of the depth of the adjusting channel 9 and the distance between the opening end of the U-shaped clip 6.

[0019] The button body 1 has a locking hole 5 on one end corresponding to the insertion path of the connecting rod 3. The button body 1 has a cylindrical fastening cavity coaxially connected to the locking hole 5. A first magnetic piece is embedded at the end of the connecting rod 3, and a second magnetic piece is embedded at the corresponding position at the bottom of the locking hole 5. The first magnetic piece and the second magnetic piece are arranged with opposite poles to form an axial magnetic attraction, and are positioned by magnetic attraction.

[0020] Two sets of elastic fastening components are arranged symmetrically along the radial direction inside the fastening cavity. The elastic fastening components include a U-shaped clamp 6, a fixed base 7, and a return spring 8. The U-shaped clamp 6 is elastic.

[0021] The open end of the U-shaped clip 6 forms a sliding fit with the inner wall of the fastening cavity through the guide rail structure, which makes it easy for the open end of the U-shaped clip 6 to slide outward to expand the gap, so that the slot 11 can be disengaged from the serration 4, making it easy to separate the rivet 2 from the button body 1.

[0022] The U-shaped clip 6 has a slot 11 on its inner side that matches the saw teeth 4 of the connecting rod 3. The inclination angle of the slot 11 forms a complementary interlocking contact with the tooth surface of the saw teeth 4, which facilitates the fixing of the nail 2.

[0023] The free end of the U-shaped clamp 6 extends towards the axis of the locking hole 5 to form a triangular interlocking protrusion. The fixed base 7 is fixed in the inner space of the two U-shaped clamps 6. The two ends of the return spring 8 are respectively connected to the side wall of the fixed base 7 and the inner wall of the U-shaped clamp 6. The free end of the U-shaped clamp 6 is kept in a state of contraction towards the center under the pre-tightening force of the return spring 8, making the connection more stable.

[0024] The locking hole 5 is provided with an annular adjustment base 10. The adjustment base 10 is fixedly connected to the wall of the fastening cavity. Its annular inner surface maintains a preset gap with the free end of the U-shaped clip 6. The side wall of the button body 1 is provided with an adjustment channel 9 for the adjustment rod to extend into and squeeze the U-shaped clip 6, thereby expanding the width of the opening end of the U-shaped clip 6 and making it easier to remove the connecting rod 3.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
