[0032] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] like Figure 1 , Figure 2 , Figure 7 As shown, a quick positioning and connection device of this utility model includes a first component, a second component, and a third component. A first positioning component 4 is installed on the first component, and a second positioning component 5 is installed on the second component. When the first component and the second component are connected, the first positioning component 4 and the second positioning component 5 are used for quick positioning and connection, so that the third component can quickly connect and lock the first component and the second component. The connection relationship between the first component, the second component, and the third component is a threaded connection or a snap-fit ​​connection.

[0034] It should be noted that this utility model is not limited to flashlights; the following example only uses flashlights.

[0035] Example 1, as Figure 1-6 and Figure 11 As shown, when the first component, the second component, and the third component are threaded connections;

[0036] The first component is a stud 7, the second component is a positioning post 8, and the third component is a nut 9. The nut 9 is rotatably mounted on the outer circumferential surface of the positioning post 8, and the inner circumferential surface of the nut 9 can be threadedly connected to the outer circumferential surface of the stud 7. The suspension component 2 is detachably connected to the upper end of the stud 7, including but not limited to various connection methods such as plug-in, snap-in, and fastening. The assembly component 3 is detachably connected to the lower end of the positioning post 8, including but not limited to various connection methods such as plug-in, snap-in, and fastening. A sealing ring 22 is provided on the outer circumferential surface of the nut 9, and there is at least one sealing ring 22.

[0037] The positioning post 8 is provided with a snap-fit ​​structure 10, which includes a housing 17. The outer circumferential surface of the stud 7 is provided with an installation groove 18. The housing 17 is installed in the installation groove 18. A steel ball 19 is installed at one end of the housing 17. A spring 20 is provided inside the housing 17. One end of the spring 20 contacts the inner wall of the housing 17, and the other end of the spring 20 contacts the steel ball 19, which is used to enable the steel ball 19 to retract and pop out. The upper end of the nut 9 is provided with the same number of slots 21 as the snap-fit ​​structure 10. When the nut 9 and the stud 7 are fully threaded, the steel ball 19 can be locked into the slot 21.

[0038] The first positioning component 4 includes an upper protective shell 11 and an upper magnetic block 14. The lower end of the stud 7 is coaxially provided with an upper placement groove 13. The upper protective shell 11 is installed in the upper placement groove 13, and the upper magnetic block 14 is embedded inside the upper protective shell 11. The second positioning component 5 includes a lower protective shell 12 and a lower magnetic block 16. The upper end of the positioning post 8 is coaxially provided with a lower placement groove 15. The lower placement groove 15 is perpendicular to the upper placement groove 13. The lower protective shell 12 is installed in the lower placement groove 15, and the lower magnetic block 16 is embedded inside the lower protective shell 12. The upper magnetic block 14 can be magnetically connected to the lower magnetic block 16.

[0039] In practical use, the lanyard can be connected to accessory 3, which then functions as the lanyard. The suspension component 2 is connected to the tail of the flashlight, allowing the stud 7 to connect to the tail of the flashlight. The magnetic attraction of the upper magnetic block 14 and the lower magnetic block 16 helps the positioning post 8 quickly align with the stud 7, eliminating the need for manual precision positioning. The upper protective shell 11 and the lower protective shell 12 protect the upper magnetic block 14 and the lower magnetic block 16, increasing their strength and extending their service life. Then, the nut 9 is rotated, causing its internal thread to engage with the external thread of the stud 7, pushing the nut 9 axially closer to the flashlight. As the threads of the nut 9 and the stud 7 rotate... During the process, the spring 20 is compressed so that the steel ball 19 enters the housing 17. When the nut 9 is rotated to be fully tightened with the stud 7, the steel ball 19 will be fully engaged with the slot 21, so that the spring 20 can release its elastic force, causing the steel ball 19 to pop out of the housing 17 and embed into the slot 21. The steel ball 19 makes a "click" sound when it is engaged with the slot 21, indicating that the connection is in place. This helps to determine whether the nut 9 and the stud 7 are properly engaged, and also improves the engagement effect, thereby connecting the lanyard to the flashlight. Furthermore, by rotating the nut 9 in the opposite direction, the positioning post 8 and the lanyard can be removed, making it easy to separate the lanyard from the flashlight.

[0040] Furthermore, when there is a fixing groove at the bottom of the flashlight, the hanging part 2 at the upper end of the stud 7 can be removed, and the stud 7 can be directly fixed in the fixing groove at the bottom of the flashlight. Repeating the above operation can also connect the lanyard to the flashlight. When the nut 9 and the stud 7 are rotated and locked, the outer sealing ring 22 enters the fixing groove at the bottom of the flashlight, is squeezed and sticks tightly to the groove wall to form a sealing ring, preventing external dust or water from seeping in from the gap between the stud 7 and the fixing groove.

[0041] When the accessory 3 is a universal spherical part, the external device can be connected to the tail or bottom of the flashlight by engaging the universal spherical part with the universal positioning groove opened on the external device. The external device can be disassembled by rotating the nut 9 in the opposite direction, so that the device can be used in different environments and meet different needs. The applicable environment of this embodiment includes, but is not limited to, flashlights, and can also be used in photography equipment or other electrical equipment.

[0042] In Example 2, to be suitable for various usage environments, the inner wall of the stud 7 can be directly threaded to the outer circumferential surface of the positioning post 8. In this case, the upper placement groove 13 is set at the bottom of the stud 7, and the lower placement groove 15 is set at the upper end face of the nut 9. Thus, during use, the nut and the stud can be quickly aligned by the magnetic connection between the upper magnetic block 14 and the lower magnetic block 16, and the positioning post can be rotated to thread them together with the stud.

[0043] Example 3, as Figure 1 and Figure 7-11 As shown, when the first component, the second component, and the third component are connected by snap-fit;

[0044] The first component is a swivel sleeve 24, the second component is a positioning sleeve 25, and the third component is a plug post 23. The positioning sleeve 25 is coaxially and slidably fitted onto the outer circumferential surface of the plug post 23. The suspension component 2 is detachably connected to the upper end of the swivel sleeve 24, including but not limited to various connection methods such as insertion, snap-fit, and fastening. The assembly 3 is detachably connected to the lower end of the positioning sleeve 25, including but not limited to various connection methods such as insertion, snap-fit, and fastening. At this time, the assembly 3 can limit the positioning sleeve 25, so that the positioning sleeve 25 is fixed on the plug post 23. Multiple insertion blocks 26 are evenly arranged on the upper end of the outer circumferential surface of the plug post 23. The inner wall of the swivel sleeve 24 is evenly provided with the same number of spiral grooves 27 as the insertion blocks 26. Each insertion block 26 can be spirally snapped and fixed with one spiral groove 27.

[0045] The sleeve 24 is equipped with a snap-fit ​​structure 28, which includes a housing 35. The inner circumferential surface of the sleeve 24 is provided with an installation groove 36. The housing 35 is installed in the installation groove 36. A steel ball 37 is installed at one end of the housing 35. A spring 38 is provided inside the housing 35. One end of the spring 38 contacts the inner wall of the housing 35, and the other end of the spring 38 contacts the steel ball 37, which is used to enable the steel ball 37 to retract and pop out. The lower end of the insert post 23 is provided with the same number of slots 39 as the snap-fit ​​structure 28. When the insert block 26 and the spiral groove 27 are completely screwed and fixed, the steel ball 37 can be snapped into the slot 39.

[0046] The first positioning component 4 includes an upper protective shell 29 and an upper magnetic ring 32. The lower end of the rotating sleeve 24 has an upper placement groove 31. The upper protective shell 29 is installed in the upper placement groove 31, and the upper magnetic ring 32 is embedded inside the upper protective shell 29. The second positioning component 5 includes a lower protective shell 30 and a lower magnetic ring 34. The upper end of the positioning sleeve 25 has a lower placement groove 33. The lower placement groove 33 is axially opposite to the upper placement groove 31. The lower protective shell 30 is installed in the lower placement groove 33, and the lower magnetic ring 34 is embedded inside the lower protective shell 30. The upper magnetic ring 32 can be magnetically connected to the lower magnetic ring 34.

[0047] In practical use, the lanyard can be connected to accessory 3, which then functions as the lanyard. The suspension component 2 is connected to the tail of the flashlight, allowing the rotating sleeve 24 to connect to the tail of the flashlight. The magnetic attraction of the upper magnetic ring 32 and the lower magnetic ring 34 helps the positioning sleeve 25 and the insertion post 23 quickly align with the rotating sleeve 24 without requiring manual precision positioning. The upper protective shell 29 and the lower protective shell 30 protect the upper magnetic ring 32 and the lower magnetic ring 34, increasing their strength and extending their service life. Subsequently, rotating the positioning sleeve 25 causes the insertion post 23 to rotate synchronously. The insertion block 26 at the lower end of the outer circumference of the insertion post 23 slides spirally along the spiral groove 27 on the inner wall of the rotating sleeve 24. As the insertion post 23 rotates, the insertion block 26 gradually moves towards the end of the spiral groove 27, achieving a tight connection. Furthermore, during the rotation of the plug block 26 and the spiral groove 27, the spring 38 is compressed, allowing the steel ball 37 to enter the housing 35. When the plug block 26 slides to the end of the spiral groove 27, that is, when the plug block 26 and the spiral groove 27 are completely spirally engaged and fixed, the steel ball 37 will be fully engaged with the slot 39. Thus, the spring 38 can release its elastic force, causing the steel ball 37 to pop out of the housing 35 and embed into the slot 39. When the steel ball 37 is engaged in the slot 39, it makes a "click" sound, indicating that the connection is in place. This helps to determine whether the plug block 26 and the spiral groove 27 are properly engaged, and also improves the engagement effect. This allows the lanyard to be connected to the flashlight. Moreover, by rotating the positioning sleeve 25 in the opposite direction, the positioning sleeve 25 and the plug 23 can be removed, making it easy to separate the lanyard from the flashlight.

[0048] Furthermore, when there is a fixing groove at the bottom of the flashlight, the hanging part 2 at the upper end of the screw sleeve 24 can be removed, and the screw sleeve 24 can be directly installed in the fixing groove at the bottom of the flashlight. Repeating the above operation can also connect the lanyard to the flashlight.

[0049] When the accessory 3 is a universal spherical part, the external device can be connected to the tail or bottom of the flashlight by engaging the universal spherical part with the universal positioning slot opened on the external device. The external device can be disassembled by rotating the positioning sleeve 25 in the opposite direction, so that the device can be used in different environments and meet different needs.

[0050] This utility model can be universally connected with a variety of devices, with a wide range of compatibility. It can achieve standardized structural interfaces, rapid switching and reuse, effectively reduce the time of misoperation, improve connection efficiency, and reduce the probability of connection failure. For example, when used in low visibility scenarios such as underwater or at night, this device can quickly perform positioning and alignment through the first positioning component 4 and the second positioning component 5, shortening the alignment time and improving efficiency. At the same time, it can be quickly disassembled and assembled through threaded or snap-fit ​​connections, thus ensuring connection strength, meeting portability requirements, and possessing good reliability and practicality, making it suitable for various scenarios.
