DETAILED DESCRIPTION

[0028] See also Figure 1-Figure 3 In an embodiment of the present invention, a portable miniature GPS positioning device comprises a shell 1 and a bottom plate 2 rotatably connected to the bottom of the shell 1, a core barrel 12 is rotatably connected inside the shell 1, a miniature GPS locator 6 is embedded in the core barrel 12, the end of the core barrel 12 is fixedly connected to the bottom plate 2, a strap 4 is penetrated through the core barrel 12, through holes 11 are symmetrically penetrated on both sides of the shell 1 for the two ends of the strap 4 to pass through respectively, baffles 13 are symmetrically fixedly connected to the periphery of both ends of the core barrel 12, a gear ring 14 is fixedly connected to the periphery of a baffle 13, and a positioning component 5 that is snap-fitted with the gear ring 14 is connected to the side of the shell 1.

[0029] In this scheme, the micro GPS locator 6 is a micro GPS locating structure commonly used in the prior art, preferably cylindrical, and the placement position is located above the position where the strap 4 passes through the core barrel 12. Under normal conditions, the positioning component 5 is in a clamping limit state with respect to the toothed ring 14. After pressing the positioning component 5, the positioning component 5 releases the clamping limit with respect to the toothed ring 14, and at this time, the shell 1 and the bottom plate 2 can rotate relatively. In this way, when relatively rotating, the strap 4 can be wound around the outer periphery of the core barrel 12 or the strap 4 can be unwound from the outer periphery of the core barrel 12 by rotation, so that the length of the two ends of the strap 4 extending from the through hole 11 can be adjusted, which can be adjusted according to the diameter of the user's hand, so that it can be worn like a watch. After loosening the positioning component 5, the positioning component 5 resumes the clamping fit with the toothed ring 14, so as to fix the length. Compared with the prior art, this method is more flexible and convenient in length adjustment, and there will be no longer part extending outside to cause dragging and affect wearing. Similarly, if it is not worn, it is more convenient to store, which is more conducive to use in more scenes.

[0030] Further, such as Figure 2 As shown, one end of the binding strap 4 is threaded, and the other end is rotatably sleeved with a connecting screw sleeve 41. The connecting screw sleeve 41 and the thread on the outer periphery of the end of the binding strap 4 form a threaded fit, which facilitates connection and fixation.

[0031] In this scheme, if Figure 3-Figure 4 As shown, further, a clamping plate 3 is installed at the bottom of the base plate 2, and the clamping plate 3 includes a fixed fan plate 31 fixedly connected to the side of the base plate 2 away from the shell 1, and a rotating fan plate 32 is rotatably connected to one side of the fixed fan plate 31 through a hinge or a hinge. The fixed fan plate 31 and the rotating fan plate 32 are both semicircular plates, and the fixed fan plate 31 and the rotating fan plate 32 form a complete circle, which is slightly smaller than the base plate 2 and is concentrically arranged with the base plate 2. The fixed fan plate 31 is hollow inside, and a magnetic piece 33 is embedded on the surface of the fixed fan plate 31. An active magnetic column 34 is arranged on the rotating fan plate 32. When the rotating fan plate 32 rotates and fits relative to the fixed fan plate 31, the end faces of the magnetic piece 33 and the active magnetic column 34 are aligned, and the ends of the active magnetic column 34 and the magnetic piece 33 are opposite. The parts are magnetically attracted to each other. Preferably, the bottom plate 2 is made of iron-based material, and the length of the movable magnetic column 34 is shorter than the thickness of the rotating fan plate 32. The movable magnetic column 34 can slide in the rotating fan plate 32. With such an arrangement, when the rotating fan plate 32 is flipped and fitted onto the bottom plate 2, the movable magnetic column 34 slides on the rotating fan plate 32, and the end of the movable magnetic column 34 slides and fits onto one side of the bottom plate 2, thereby maintaining an adsorption state. In this way, the fixed fan plate 31 and the rotating fan plate 32 can remain in a flat state, and when the rotating fan plate 32 is flipped and fitted onto the fixed fan plate 31, the movable magnetic column 34 slides on the rotating fan plate 32, and its end moves and fits onto one side of the magnetic sheet 33 and forms adsorption, so that this state can be maintained, thereby forming a clamping effect. For thinner clothing or accessories, clamping placement can be formed in this way. Preferably, a liner ring 3401 is fixedly provided in the middle part of the outer periphery of the movable magnetic column 34, and the liner ring 3401 is slidably fitted in the rotating fan plate 32, so that the movable magnetic column 34 can be prevented from falling off, and through the setting of the liner ring 3401, when the rotating fan plate 32 rotates to the side of the fixed fan plate 31, the liner ring 3401 slides to fit with the side of the rotating fan plate 32 facing the fixed fan plate 31, and when the rotating fan plate 32 rotates to the side of the bottom plate 2, the liner ring 3401 slides to fit with the side of the rotating fan plate 32 facing the bottom plate 2. This method can conveniently avoid the shaking of the rotating fan plate 32.

[0032] like Figure 5-Figure 7As shown, an arc-shaped opening 35 is embedded in the side of the fixed fan plate 31 away from the bottom plate 2, a clamping plate 37 is elastically connected inside the fixed fan plate 31, and one side of the clamping plate 37 extends out from the arc-shaped opening 35, and a push block 38 is fixedly connected at the opposite edges of the rotating fan plate 32 and the fixed fan plate 31, and the length of the push block 38 is less than the thickness of the fixed fan plate 31 or the rotating fan plate 32, so as not to affect the rotation of the rotating fan plate 32 relative to the fixed fan plate 31, and when the rotating fan plate 32 rotates to fit on the surface of the bottom plate 2, the push block 38 pushes the part of the clamping plate 37 extending out of the arc-shaped opening 35 to move into the fixed fan plate 31.

[0033] Furthermore, an arc-shaped rubber pad 36 is inlaid on the surface of the rotating fan plate 32 corresponding to the arc-shaped opening 35, and the clamping plate 37 includes a spring steel sheet 3702 connected to the inside of the fixed fan plate 31 close to the rotating fan plate 32, and an arc-shaped plate 3701 is fixedly connected to one end of the spring steel sheet 3702 close to the arc-shaped opening 35, and the arc-shaped plate 3701 is adapted in size to the arc-shaped opening 35, and a plurality of groups of clamping teeth 3703 are fixedly connected to the arc-shaped plate 3701 toward the side of the arc-shaped opening 35. When the push block 38 is not pushed into the fixed fan plate 31, the clamping teeth 3703 on one side of the arc plate 3701 extend from the arc opening 35. When the rotating fan plate 32 rotates relative to the fixed fan plate 31 and the push block 38 is completely pushed into the fixed fan plate 31, the inclined spring steel sheet 3702 can be flattened, so that the arc plate 3701 sinks from the arc opening 35 into the fixed fan plate 31. This makes it convenient to wear, and the rotating fan plate 32 and the fixed fan plate 31 will not cause discomfort. When clamping is needed, the fixed fan plate 31 and the rotating fan plate 32 are rotated and clamped, and the clamping teeth 3703 and the matching arc rubber pad 36 are clamped, and the elastic state of the spring steel sheet 3702 can remain clamped.

[0034] like Figure 8 As shown, a plurality of balls are movably embedded in the through hole 11. When the end of the strap 4 extends from the through hole 11, the balls can reduce resistance, making the operation more flexible and convenient.

[0035] like Figure 9-11 As shown, the positioning assembly 5 includes a button 51 elastically passing through the side wall of the shell 1 and a latch tooth 52 that is engaged with the gear ring 14. The side wall of the shell 1 is connected with a guide assembly. When the button 51 moves into the shell 1, the button 51 pulls the latch tooth 52 away from the gear ring 14 through the guide assembly, thereby disengaging from the rotation restriction of the gear ring 14. When the button 51 is released, the end of the button 51 returns to be away from the shell 1, and the latch tooth 52 approaches the gear ring 14 and engages with the gear ring 14 to limit the position.

[0036] The guide assembly includes a guide rail 53 fixedly connected to the inner wall of the housing 1, the guide rail 53 is located below the button 51, a slider 54 is slidably provided on the guide rail 53, the latching tooth 52 is fixedly mounted on the slider 54, a spring is connected between the slider 54 and the inner wall of the housing 1 to push the slider 54 close to the gear ring 14, multiple groups of guide wheels 55 are connected to the inner wall of the housing 1 between the guide rail 53 and the button 51, a traction rope 56 is connected to the button 51, the traction rope 56 is wound through the guide wheel 55, and is fixedly connected to one side of the slider 54. In this way, when the button 51 is pressed, the slider 54 can be pulled by the traction rope 56 to drive the latching tooth 52 away from the gear ring 14, and after releasing, all structural parts can be restored to their original state under the restoring action of the spring on the slider 54. This solution is simple to operate and has a fast response speed.
