Abstract
Description
Technical Field
[0001] This utility model relates to the field of quick-release buckles, and more specifically to quick-release buckles that can be hung and removed with one hand. Background Technology
[0002] Quick-release buckles are mechanical structures that allow one part to quickly engage with another or close completely. They are very common in daily life, such as keychains, serving a connecting function and can be applied in different scenarios according to different user needs. Taking quick-release keychains as an example, in actual use, keychains are usually hung on clothing. When using the keys, the keychain needs to be removed. However, to prevent accidental opening and loss of items, most existing quick-release buckles cannot be easily opened with one hand. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a one-handed quick-release buckle, which can realize one-handed quick-release.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows:
[0005] The single-hand quick-release buckle includes an inner tube with a connector II fixed at one end. Multiple spherical holes are provided through the outer side of the inner tube away from the connector II. Each of the spherical holes contains a limiting ball. An outer tube is fitted and slidably around the inner tube to limit the limiting balls. An annular groove is provided inside the outer tube. The buckle also includes a connector I with a plug at one end. A slot is provided between the plug and connector I. When the plug is inserted into the inner tube, the multiple limiting balls are located in the slot, forming a limiting connection between connector I and the inner tube. Both connector I and connector II have through-holes.
[0006] There is a ring ridge inside the outer tube near the connector II end, and a spring is provided between the ring ridge and the inner tube to make the ring ridge press tightly against the connector II.
[0007] The outer surface of the outer tube is provided with anti-slip features.
[0008] The outer surface of the outer tube has an arc groove recessed in the center.
[0009] The plug has a chamfer at the end away from connector I.
[0010] The plug also has a chamfer near the connector I end.
[0011] The inner tube contains a magnet.
[0012] A magnetic block is provided at the end face of the plug away from connector I.
[0013] The connector II is provided with a threaded head near the inner tube end, and the threaded head is threadedly connected to the inner wall of the inner tube.
[0014] During installation, adhesive is applied to the threaded ends.
[0015] The beneficial effects of this utility model are:
[0016] 1. When disassembling or installing the connection, the plug can be slid out or into the inner tube by pushing the outer tube away from the connector II with one hand, thus completing the quick-release and hook-and-go operation with one hand.
[0017] 2. When the outer tube is accidentally moved away from connector II, the magnetic force of the magnet and the magnetic block can further prevent connector I from separating and being lost. Attached Figure Description

[0027] 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.
[0028] like Figure 1-7 The following is a detailed explanation of how to hook and unhook quick-release buckles with one hand:
[0029] The quick-release buckle for single-handed hooking includes an inner tube 1 with a connector II 11 fixed at one end. Multiple spherical holes 2 are provided through the outer side of the inner tube 1 away from the connector II 11. Each of the multiple spherical holes 2 contains a limiting ball 3. An outer tube 12 is fitted and slidably on the outside of the inner tube 1 to limit the limiting balls 3. An annular groove 13 is provided inside the outer tube 12. It also includes a connector I 7 with a plug 6 at one end. A slot 8 is provided between the plug 6 and the connector I 7. When the plug 6 is inserted into the inner tube 1 and the multiple limiting balls 3 are located in the slot 8, a limiting connection is formed between the connector I 7 and the inner tube 1. Both the connector I 7 and the connector II 11 have through-holes.
[0030] The inner tube 1 has an annular shoulder on its outer side. The annular shoulder is located away from the connector II 11. Multiple spherical holes 2 are located on the annular shoulder. Each spherical hole 2 has a spherical edge near the central axis of the inner tube 1. This edge is used to limit the limiting ball 3. When the limiting ball 3 is in the spherical hole 2, it can protrude into the inner tube 1. At the same time, it is limited by the spherical edge and cannot enter the inner tube 1. Thus, when the plug 6 is inserted into the inner tube 1, multiple limiting balls 3 are located in the slot 8, which limits the plug 6 and prevents the plug 6 from sliding out of the inner tube 1. In this state, the connector I 7 is pressed against the end of the inner tube 1.
[0031] In order to ensure that the limiting ball 3 limits the plug 6 and that the inner diameter of the outer tube 12 and the outer diameter of the annular shoulder can fit together and slide, the limiting ball 3 is limited in the spherical hole 2, ensuring that the limiting ball 3 is in a state of protruding into the inner tube 1.
[0032] When it is necessary to remove connector I7, that is, to slide plug 6 out of inner tube 1, push outer tube 12 away from connector II11, so that the annular groove 13 inside outer tube 12 slides to the limiting ball 3. At this time, pull connector I7 outward, connector I7 will drive plug 6 to push the limiting ball 3, so that the limiting ball 3 retracts into the spherical hole 2 and enters the annular groove 13, thereby sliding plug 6 out of inner tube 1. In this state, although the limiting ball 3 will enter the annular groove 13, it will not completely detach from the spherical hole 2.
[0033] During installation, push the outer tube 12 to slide, so that the annular groove 13 slides to the limit ball 3. Insert the plug 6 into the inner tube 1, and then squeeze the limit ball 3 into the annular groove 13 until the connector I 7 is pressed against the inner tube 1. Then push the outer tube 12 back to press against the connector II 11 to complete the quick connection.
[0034] Taking the application of this application to keychains as an example, when in use, connector I7 and connector II11 are connected to clothing and keychain respectively. When completing the above disassembly and assembly actions, while holding the keychain, the operator can use the thumb and index or middle finger of the hand to push the outer tube 12, and then pull or push along the axis of the outer tube 12 to complete the disassembly and assembly with one hand, achieving the purpose of quick disassembly and retrieval with one hand.
[0035] Further:
[0036] The outer tube 12 has an annular ridge 14 near the connector II 11 inside. A spring 4 is provided between the annular ridge 14 and the inner tube 1 to make the annular ridge 14 press against the connector II 11.
[0037] The two ends of the spring 4 press against the ring ridge 14 and the annular shoulder respectively. The elastic force of the spring 4 will push the ring ridge 14 to move the outer tube 12 towards the connector II 11 and press against the connector II 11, thereby preventing the outer tube 12 from moving automatically towards the connector I 7 and causing the connector I 7 to be disassembled.
[0038] Further:
[0039] By providing an anti-slip feature on the outer surface of the outer tube 12, it is easy to push the outer tube 12 to move against the elastic force of the spring 4. Furthermore, by having an arc groove recessed in the center of the outer surface of the outer tube 12, the friction can be increased, making it easier to accommodate the fingertips and increasing comfort.
[0040] Further:
[0041] By providing a chamfer at the end of the plug 6 away from the connector I7, and also providing a chamfer at the end of the plug 6 near the connector I7, the plug 6 can push the limiting ball 3 back into the spherical hole 2 during disassembly and assembly, thereby further improving the speed of disassembly and assembly.
[0042] like Figure 2 As shown in Figures 4 and 5:
[0043] The inner tube 1 is equipped with a magnet 5.
[0044] The plug 6 has a magnetic block 9 at the end face away from the connector I7.
[0045] After connection and installation, magnet 5 and magnetic block 9 adhere to each other and attract each other. Thus, when the outer tube 12 is entangled by external clothing or other forms of accidental contact, causing the outer tube 12 to move against the elastic force of spring 4 and the annular groove 13 to slide to the limit ball 3, magnet 5 and magnetic block 9 will not separate when there is no external force pulling connector I7 and connector II11 in the opposite direction, so that connector I7 will not be disassembled.
[0046] Furthermore, due to the magnetic attraction between magnet 5 and magnetic block 9, when connector I7 is installed, plug 6 will be automatically drawn in when aligned with inner tube 1, improving the convenience of connection and installation.
[0047] like Figure 6 As shown:
[0048] The connector II11 is provided with a threaded head 10 near the end of the inner tube 1, and the threaded head 10 is threadedly connected to the inner wall of the inner tube 1.
[0049] During installation, the threaded head 10 is coated with adhesive.
[0050] In actual production, the outer tube 12 needs to be fitted onto the inner tube 1 near the connector II11 end to complete the installation. Therefore, the connector II11 is fixedly connected by screwing the threaded head 10 into the inner tube 1. At the same time, in order to prevent it from loosening automatically after a period of use, adhesive is applied to the threaded head 10 during installation. After tightening, the adhesive forms a bond between the two, preventing the threads from loosening automatically.
[0051] Of course, the above description is not a limitation of this instruction manual, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
