Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1 to 6 together, the locking system of the present invention will now be described. The locking system comprises an upper shell 11, a lower shell 21, a handle 31 pivoted on the upper shell 11 through a pivot 12; the lower housing 21 is provided with a detent 22, the handle 31 is provided with an elastic plate 32, the elastic plate 32 is provided with a first hook 321 for cooperating with the detent 22, and the handle 31 is provided with a pressing mechanism 4 for pressing the first hook 321 hooked on the detent 22 to the detent 22.

Thus, the lower shell 21 is provided with the detent 22, the upper shell 11 is provided with the handle 31, and the handle 31 can rotate around the pivot 12; the handle 31 is provided with an elastic plate 32, the elastic plate 32 is provided with a first hook 321, and the handle 31 is fixed after the first hook 321 is clamped on the clamping position 22; the pressing mechanism 4 presses the first hook 321 to the position-locking portion 22, so that the firmness between the first hook 321 and the position-locking portion 22 is greatly enhanced, and the handle 31 is prevented from loosening.

Optionally, in one embodiment, the flexible panel 32 is a plastic panel.

Optionally, in one embodiment, the detent 22 is a protrusion for hooking the first hook 321. In another embodiment, the detent 22 is a recess for the first hook 321 to hook.

Further, referring to fig. 1 to 6, as a specific embodiment of the latch system provided by the present invention, the pressing mechanism 4 includes a sliding slot 41 and a sliding plate 42 provided on the handle 31; the elastic plate 32 is arranged on the side wall of the chute 41, the elastic plate 32 is arranged at an interval relative to the bottom wall of the chute 41, and a slide way for the sliding plate 42 to slide is formed between the elastic plate 32 and the bottom wall of the chute 41; the elastic plate 32 is provided with a first protrusion 322 extending into the slide way, and the first hook 321 and the sliding plate 42 are respectively located at two opposite sides of the elastic plate 32. Thus, a slide way is formed between the elastic plate 32 and the bottom wall of the slide slot 41, the slide plate 42 slides in the slide way, and since the first protrusion 322 extends into the slide way, when the slide plate 42 touches the first protrusion 322, the slide plate 42 bends the elastic plate 32 toward the direction of the side where the first hook 321 is located through the first protrusion 322, and the bent elastic plate 32 presses the first hook 321 against the position-lock 22.

Further, referring to fig. 1 to 6, as an embodiment of the locking system of the present invention, the elastic plate 32 is disposed parallel to the bottom wall of the sliding groove 41. Thus, the slide plate 42 is less likely to collide when sliding between the elastic plate 32 and the bottom wall of the chute 41.

Further, referring to fig. 1 to 6, as an embodiment of the latch system of the present invention, the sliding plate 42 is provided with a second protrusion 421 protruding toward the elastic plate 32. As such, the second protruding portion 421 more easily contacts the first protruding portion 322 and pushes the elastic plate 32 to bend.

Further, referring to fig. 1 to 6, as an embodiment of the latching system of the present invention, the second protrusion 421 has a first guiding surface for guiding the second protrusion 421 to slide along the elastic plate 32. As such, the second projection 421 facilitates sliding contact along the elastic plate 32 when in contact with the elastic plate 32, guided by the first guide surface.

Further, referring to fig. 1 to 6, as a specific embodiment of the latching system provided by the present invention, a slot 411 is disposed on the bottom wall of the sliding slot 41, and a second hook 422 for being snapped into the slot 411 is disposed on the sliding plate 42. Thus, the second hook 422 prevents the sliding plate 42 from being separated from the slideway under the limitation of the slot 411.

Optionally, in one embodiment, the slot 411 extends in the same direction as the slide.

Further, referring to fig. 1 to 6, as an embodiment of the latching system of the present invention, the second hook 422 has a second guiding surface for guiding the second hook 422 to slide along the bottom wall of the slot 411. Thus, when the sliding plate 42 drives the second hooks 422 to move along the slots 411, the second guide surface can guide the second hooks 422 to slide.

Further, please refer to fig. 1 to 6, as a specific embodiment of the latching system of the present invention, a boss 4111 is disposed in the slot 411. Thus, when the second hook 422 meets the boss 4111, the second hook 422 can be limited; when the sliding plate 42 is detached, the second hooks 422 can slide out of the slots 411 through the bosses 4111.

Further, referring to fig. 1 to 6, as an embodiment of the latch system of the present invention, a push plate 13 for being pushed by a user is disposed on the sliding plate 42. In this way, the user can conveniently push the sliding plate 42 to slide by the pushing plate 13.

Further, referring to fig. 1 to 6, as an embodiment of the latch system of the present invention, the push plate 13 is perpendicular to the sliding direction of the sliding plate 42. In this way, the user can conveniently push the push plate 13 to move when pushing the sliding plate 42.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
