[0033] To make the above objects, features and advantages of the present invention more comprehensible, the following detailed description of the specific implementation manners of the present invention is provided in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] As Figures 1 - 12 shown, the present invention provides a quick self-locking buckle for an LED light bar, characterized in that the quick self-locking buckle for the LED light bar includes: a lower buckle 10, a spring 40 is fixedly arranged on the lower buckle 10, a central axis 30 is arranged on the top of the spring 40, an upper buckle 20 is arranged on the top of the central axis 30, and the upper buckle 20 presses down the central axis 30 and the spring 40 to engage with the lower buckle 10.

[0035] Specifically, one end of the spring 40 is arranged on the central axis 30, the other end of the spring 40 is arranged on the lower buckle 10. When the upper buckle 20 is pressed on the central axis 30 and rotated counterclockwise by 180° and pressed into the lower buckle 10, the upper buckle 20 and the lower buckle 10 are engaged together. The self-locking function is realized by using the reset function of the spring 40 and the torsional force generated under the acting force of rotation, and the operation is simple and convenient.

[0036] In some embodiments, a first spring limiting groove 11 is opened at the center of the top surface of the lower buckle 10, and baffles 12 are arranged on the opposite sides of the first spring limiting groove 11.

[0037] Specifically, a first spring limiting groove 11 is opened at the center of the bottom surface of the lower buckle 10 to prevent the spring 40 from causing the whole to move with the external force under the action of the external force. Baffles 12 are respectively arranged on both sides of the first spring limiting groove 11 along the length direction of the lower buckle 10 to prevent the central shaft 30 from rotating excessively downward due to the torsional force of the spring 40.

[0038] In some embodiments, at least a pair of hook-shaped first buckles 14 are arranged on the bottom surface of the lower buckle 10, and at least a pair of hook-shaped second buckles 13 are arranged on the top surface of the lower buckle 10.

[0039] Specifically, a pair of hook-shaped first buckles 14 are respectively arranged at both ends of the lower buckle 10 in the width direction for buckling with the installation groove 61 of the unit frame 60. A pair of hook-shaped second buckles 13 are respectively arranged at both ends of the top surface of the lower buckle 10 along the length direction for buckling with the upper buckle 20.

[0040] In some embodiments, the tail end of the spring 40 extends outward to cooperate with the first spring limiting groove 11, and the top end of the spring 40 extends inward.

[0041] Specifically, the tail end of the spring 40 has a structure extending outward to cooperate with the first spring limiting groove 11, and the top end of the spring 40 has a structure extending inward.

[0042] In some embodiments, the bottom center of the central shaft 30 is concave, and a second limiting groove 33 is arranged therein. The second limiting groove 33 cooperates with the top end of the spring 40. Two opposite dial pieces 32 are arranged on the outer surface of the bottom of the central shaft 30, and a plurality of convex blocks 31 are arranged at the bottom end of the central shaft 30.

[0043] Specifically, the bottom of the central shaft 30 is concave, and a second limiting groove 33 is arranged in the center to cooperate with the top end of the spring 40. Two dial pieces 32 are arranged on the outer surface of the bottom end of the central shaft 30, and the two dial pieces 32 are arranged oppositely for unlocking. Four upwardly protruding convex blocks 31 are further arranged at the bottom end of the central shaft 30 for fixing the central shaft 30 to prevent the central shaft 30 from rotating by itself under the action of the torsional force of the spring 40.

[0044] In some embodiments, a first through hole 23 is arranged in the middle of the upper buckle 20. The first through hole 21 matches the top of the central shaft 30. Second through holes 23 are respectively arranged at both ends of the upper buckle 20 in the length direction. A plurality of grooves 22 matching the convex blocks 31 are arranged on the first through hole 21.

[0045] Specifically, a first through hole 21 is formed in the middle of the upper buckle 20. The first through hole 21 is matched with the top of the central shaft 30, so that the top of the central shaft 30 can pass through the first through hole 21 and expose on the upper buckle 20. Second through holes 23 are respectively arranged in the length direction of the upper buckle 20. The second through holes 23 are used to fix the self-locking device on the lamp strip 50 to prevent the self-locking device from sliding on the lamp strip 50. Four grooves 22 matched with the bumps 31 are arranged at the bottom end of the first through hole 21, so that the central shaft 30 is pressed against the lower part of the upper buckle 20 under the action of the spring 40. The top of the central shaft 40 passes through the first through hole 21 and exposes the upper buckle 20. The bumps 31 of the central shaft 30 are stuck on the grooves 22 on the bottom surface of the first through hole 21. The upper buckle 20 and the lower buckle 10 are buckled together, so that the central shaft 30 cannot be driven to rotate under the torsional force of the spring 40.

[0046] In some embodiments, positioning posts 15 are respectively arranged at both ends of the bottom surface of the lower buckle 10 in the length direction. The positioning posts 15 are located between the first buckles 14.

[0047] Specifically, positioning posts 15 are respectively arranged at both ends of the bottom surface of the lower buckle 10 in the length reverse direction for positioning when the self-locking device is connected to the outside.

[0048] In some embodiments, a waist-shaped clamping plate is arranged at the top of the central shaft. The waist-shaped clamping plate is fixedly connected to the bottom end of the central shaft.

[0049] Specifically, the waist-shaped clamping plate is integrally formed with the central shaft and is arranged above the bottom end of the central shaft.

[0050] During assembly, the tail end of the spring 40 is placed in the first spring limiting groove 11 of the lower buckle 10, and the top end of the spring 40 is placed on the second spring limiting groove 33 of the central axis 30. The upper buckle 20 is pressed onto the central axis 30 so that the top of the central axis 30 passes through the first through hole 21 and is exposed on the upper buckle 20. The protrusion 31 is engaged with the groove 22. The upper buckle 20 is rotated to drive the central axis 30, thereby driving the spring 40, and rotating 180° counterclockwise to press into the lower buckle 10 so that the upper buckle 20 and the lower buckle 10 are engaged. At this point, the assembly is completed. It can be seen that the present invention has a simple structure and is quick to assemble. When it is necessary to connect with the light bar 50, it is only necessary to align the light bar 50 with the waist-shaped card plate 34 of the central axis 30 and press it to move the central axis 30 downward. The protrusion 31 is separated from the restriction of the groove 22 and the central axis 30 rotates clockwise under the torsional force of the spring 40. 90°, due to the cooperation between the paddle 32 and the baffle 12, the central axis 30 can only be rotated 90° clockwise, and there is no need to worry about the central axis 30 rotating too much; the waist-shaped card plate 34 is used to clamp the light bar 50, and a limit block 51 is provided on the light bar 50, which is connected to the second through hole 23 of the upper buckle 20 through a fastener 52 to prevent the self-locking device from sliding on the light bar 50; and then the positioning column 15 is inserted into the positioning hole 62, and the first buckle 14 is buckled on the mounting groove 61, so that the installation is completed. When it needs to be removed, it is only necessary to use a tool or hand to pry the paddle 32 to overcome the torsional force of the spring 40 and let the central axis 30 rotate 90° counterclockwise. The waist-shaped card plate 34 is restored to its original state, and the self-locking device can be opened; it can be seen from the above that the present invention is extremely simple to operate in both installation and disassembly, saving installation and disassembly time, thereby improving efficiency.

[0051] In summary, the present invention includes a lower buckle 10, on which a spring 40 is fixed, on the top of which a central axis 30 is provided, on which a top buckle 20 is provided, and on which a central axis 30 is pressed down by the top buckle 20 and the spring 40 is buckled with the lower buckle 10. With the above design, by putting the light bar into the top buckle and pressing it, the central axis can rotate and automatically lock the light bar by using the pre-torsion force of the spring, and the central axis paddle can be turned to rotate the central axis to a predetermined position, and when the long side direction of the waist-shaped card plate is consistent with the direction of the light bar limit groove, the light bar is disengaged from the self-locking buckle. The structure is simple, easy to assemble, easy to operate, saving installation and disassembly time, and improving efficiency.

[0052] The above-mentioned embodiments only express one or more implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
