[0026] 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.

[0027] Please see Figure 1-7 A quick-release power adapter structure includes an upper housing 1 and a lower housing 2. A charging circuit board 3 is housed inside the lower housing 2. An input power line 4 and an output power line 5 are respectively provided at both ends of the lower housing 2. In this application, both the input power line 4 and the output power line 5 are electrically connected to the charging circuit board 3. A support plate 6 is fixedly connected to the inner wall of the lower housing 2. The width of the support plate 6 is adapted to the inner width of the upper housing 1, allowing the support plate 6 to slide into the upper housing 1. The height of the support plate 6 is less than the inner width of the upper housing 1. The support plate 6 has a U-shaped structure. The lower housing 2 can maximize the use of internal space. A precision lead screw 71 is threaded onto the support plate 6 and is rotatably connected to the upper housing 1. The precision lead screw 71 is rotatably connected to the upper housing 1 through a bearing. A knob 7 is fixedly connected to the top of the precision lead screw 71. By turning the knob 7, the precision lead screw 71 can be screwed into the support plate 6. During this process, the lower housing 2 can move and tighten onto the upper housing 1, so that the upper housing 1 can be docked and assembled with the lower housing 2. The upper housing 1 is provided with a locking component 8 for locking the knob 7.

[0028] The lower housing 2 has a raised edge around its top periphery, and the upper housing 1 has a groove around its bottom periphery that matches the raised edge. The fit between the raised edge and the groove can improve the tightness of the mating between the upper housing 1 and the lower housing 2 when the upper housing 1 and the lower housing 2 are tightly connected.

[0029] The locking assembly 8 includes a bracket 81, which is fixedly connected to the upper surface of the upper housing 1. A torsion spring shaft 82 is provided on the inner side of the bracket 81, and a pressure plate 83 is provided on the torsion spring shaft 82. A locking plate 84 is fixedly connected to one end of the pressure plate 83. The pressure plate 83 is rotatably connected to the bracket 81 through the torsion spring shaft 82. The torsion spring shaft 82 is composed of a torsion spring and a shaft. In this way, the torsion spring shaft 82 can give the pressure plate 83 the ability to rotate and return to its original position. By flexibly locking the locking plate 84 into the knob 7, the deflection of the precision lead screw 71 due to vibration can be prevented.

[0030] The knob 7 is located on the upper surface of the upper housing 1. The knob 7 is provided with a slot for engaging the card plate 84. There are multiple slots, which can provide multiple engagement positions for the card plate 84.

[0031] A pressure frame 9 is provided on the inner side of the support plate 6. An elastic connector 10 is provided on the pressure frame 9 and the support plate 6. A pressing component 11 is provided on the support plate 6. The pressure frame 9 and the pressing component 11 abut against each other, and the pressing component 11 abuts against the inner wall of the upper housing 1.

[0032] The number of elastic connectors 10 is one pair. The elastic connector 10 includes a T-shaped slide rod 101, which is fixedly connected to the inner top of the pressure frame 9. A compression spring 102 is sleeved on the T-shaped slide rod 101. The pressure frame 9 is slidably connected to the T-shaped slide rod 101. The two ends of the compression spring 102 are fixedly connected to the opposite surfaces of the T-shaped slide rod 101 and the pressure frame 9. The pressure frame 9 can slide on the T-shaped slide rod 101, and the compression spring 102 can make the pressure frame 9 have an elastic restoring effect.

[0033] The number of pressing components 11 is one pair. The pressing component 11 includes a slant seat 111. One end of the slant seat 111 is fixedly connected to a rectangular pressure rod 112. The rectangular pressure rod 112 is slidably connected to both sides of the support plate 6. A second pressure spring 113 is sleeved on the rectangular pressure rod 112. The two ends of the second pressure spring 113 are fixedly connected to the opposite surfaces of the support plate 6 and the slant seat 111. In this application, the rectangular pressure rod 112 slides on the support plate 6 and extends out. One end of the extended rectangular pressure rod 112 can be used to press against the upper housing 1. In this way, after the upper housing 1 and the lower housing 2 are connected through the support plate 6 and the precision lead screw 71, the rectangular pressure rod 112 can further improve the stability of the docking of the upper housing 1 and the lower housing 2.

[0034] Both ends of the pressure frame 9 are provided with inclined surfaces. The inclined seat 111 is slidably connected to the inclined surface of the pressure frame 9. The inclined surface of the pressure frame 9 can easily push the inclined seat 111 to move laterally. The inner wall of the upper housing 1 is provided with an inner groove for the insertion of the rectangular pressure rod 112. The inner groove in this application is a rectangular and relatively long groove. Since the size of the support plate 6 is compatible with the inner size of the upper housing 1, in order to ensure that the rectangular pressure rod 112 is effectively pressed against the inner wall of the upper housing 1, an inner groove is reserved on the inner wall of the upper housing 1, which facilitates the entry of the rectangular pressure rod 112.

[0035] It is worth noting that in order to increase the friction between the rectangular pressure bar 112 and the upper housing 1, the end of the rectangular pressure bar 112 away from the inclined seat 111 should be treated with anti-slip treatment, such as adding an anti-slip pad.

[0036] When this utility model is in use, the support plate 6 fixed on the lower housing 2 is slid into the upper housing 1. At this time, the clamping plate 84 should be disengaged from the corresponding clamping slot by pressing the pressure plate 83. At this time, the precision lead screw 71 can be rotated by the knob 7. The support plate 6 is provided with a screw hole for the precision lead screw 71 to be screwed in, so the precision lead screw 71 can be screwed into the support plate 6.

[0037] During the threaded insertion of the precision lead screw 71, the precision lead screw 71 can enter the inner side of the support plate 6 and push the pressure frame 9 down. The descending pressure frame 9 can squeeze the inclined seat 111. At this time, the compression spring 113 can be compressed, and the rectangular pressure rod 112 can enter the inner groove to press against the upper housing 1. At the same time, since the precision lead screw 71 is threadedly connected to the support plate 6, the upper housing 1 and the lower housing 2 are tightened together during the threaded insertion of the precision lead screw 71 into the support plate 6, and the convex edge aligns with the groove. In this way, the upper housing 1 and the lower housing 2 can be quickly assembled. The assembly of the upper housing 1 and the lower housing 2 can have double locking properties and high connection stability.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
