[0037] With reference to Figures 1 to 11 The working principle of the self-locking type convenient cover opening flashlight is as follows:

[0038] The pushing table 42 is manually pushed downward, the pushing table 42 moves downward in the limiting hole 33, and then drives the whole locking piece 4 to slide downward until the limiting table 41 on the locking piece 4 slides from the limiting groove 34 at the upper end to the limiting groove 34 at the lower end, the locking piece 4 stops moving, at this moment, the rotating shaft 5 is located at the upper end of the sliding hole 43, the pressing end of the clamping piece 3 is pressed, the pressing spring 51 is compressed, and the locking piece 4 and the clamping piece 3 are rotated together around the rotating shaft 5, since the radius of rotation R1 of the locking piece 4 does not change (i.e., the distance R1 from the center of the rotating shaft 5 to the circular arc surface 45 does not change, as shown in the figure) in the process of the rotation of the locking piece 4 and the clamping piece 3 together, the pressing mark 31 on the pressing end of the clamping piece 3 is in contact with the pressing table 42 on the locking piece 4, and the clamping piece 3 is prevented from rotating relative to the barrel 1, and the flashlight is in a self-locking state. Figure 7As shown in the figure), so the clamping piece 3 is in the unlocking state at this time, and the locking piece 4 and the clamping piece 3 can rotate smoothly around the rotating shaft 5 until the clamping table 32 on the clamping piece 3 is separated from the clamping groove 22 (as shown in the figure) Figure 8 As shown in the figure), the cover body 2 can be opened by the action of the two cover opening springs 24 on the inner side of the cover body 2, and the cover body 2 is smoothly opened. The cover body 2 can be buckled with the clamping piece 3 again by pressing the cover body 2.

[0039] The pushing table 42 is pushed upward manually and moves upward in the limiting hole 33, thereby driving the entire locking piece 4 to slide upward until the limiting table 41 on the locking piece 4 slides from the lower limiting groove 34 to the upper limiting groove 34, and the locking piece 4 stops moving. At this time, the rotating shaft 5 is located at the lower end of the sliding hole 43, and the rotating radius R2 of the locking piece 4 is increased (that is, the distance R2 from the center of the rotating shaft 5 to the arc surface 45 is increased, R2>R1, as shown in the figure) Figure 9 At this time, the clamping piece 3 is in the locking state, and if the pressing end of the clamping piece 3 is pressed with force, the arc surface 45 of the locking piece 4 will interfere with the barrel body 1, so the locking piece 4 and the clamping piece 3 will not rotate around the rotating shaft 5 under the action of external force, and the cover body 2 will not be opened, thereby preventing accidental opening of the cover.

[0040] The self-locking convenient cover opening flashlight of the utility model, through synchronous rotation connection of the clamping piece 3 and the locking piece 4 at the opening end of the barrel body 1, the clamping piece 3 is used for buckling with the cover body 2, convenient cover opening is realized, the locking piece 4 is located between the clamping piece 3 and the barrel body 1 and is in limiting sliding connection with the clamping piece 3, the rotating radius of the locking piece 4 is changed, so that the locking piece 4 can press against the barrel body 1 or rotate smoothly, thereby realizing locking and unlocking of the clamping piece 3, and the flashlight has the self-locking function, and accidental opening of the cover is prevented.

[0041] The above disclosed is only the preferred embodiment of the utility model, which cannot be used to limit the protection scope of the utility model, so equivalent changes made in the patent application range of the utility model still belong to the range covered by the utility model.
