Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in an orientation or positional relationship indicated in the drawings for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be considered limiting of the invention.

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 4, the locking mechanism of the present invention will now be described. The locking mechanism comprises a lower shell 11, an upper shell 12 which is detachably covered on the lower shell 11, and a handle 3 which is pivoted on the upper shell 12 through a pivot 2; the handle 3 is provided with a sliding chute 31, one end of the sliding chute 31 is an inlet 311, and the lower shell 11 is provided with a rod body 4 which is used for sliding into the sliding chute 31 and sliding along the sliding chute 31; on the sliding path where the rod 4 enters from the entrance 311 of the slide groove 31 and slides along the slide groove 31, the distance of the sliding path from the pivot 2 gradually decreases.

Thus, after the upper shell 12 is covered on the lower shell 11, the rod 4 is firstly clamped into the inlet 311 of the chute 31, and then the handle 3 is rotated around the pivot 2, so that the rod 4 can move along the chute 31; because on the gliding sliding path of the body of rod 4 along spout 31, the distance of sliding path and pivot 2 reduces, has shortened the distance between the pivot 2 and the body of rod 4 for body of rod 4 can compress tightly last casing 12 on casing 11 down when sliding along spout 31, has ensured the fastness between casing 11 and the last casing 12 down.

Further, referring to fig. 1 to 4, as a specific embodiment of the locking mechanism of the present invention, the sliding groove 31 is a strip-shaped hole formed on the handle 3. So, the bar hole is easy to produce, and the body of rod 4 slides along the bar hole easily.

Further, referring to fig. 1 to 4, as a specific embodiment of the locking mechanism of the present invention, the rod 4 is inserted into the bar hole. So, the body of rod 4 wears to establish and is difficult to break away from in the bar-shaped hole and come out.

Further, referring to fig. 1 to 4, as a specific embodiment of the locking mechanism of the present invention, the diameter of the rod 4 is the same as the width of the bar hole. So, the condition of rocking is difficult to appear when the body of rod 4 slides along bar hole.

Further, referring to fig. 1 to 4, as an embodiment of the locking mechanism of the present invention, the inner wall of the sliding groove 31 has a concave portion protruding toward the pivot 2 and allowing the rod 4 to be inserted therein. Therefore, when the rod body 4 is clamped into the concave part, the rod body 4 can be positioned in the concave part, and the rod body 4 is prevented from sliding out along the sliding groove 31; in addition, when the rod body 4 is clamped into the concave part, the rod body 4 impacts the concave part to generate sound, and a user can judge whether the rod body 4 is clamped or not through the sound.

Further, referring to fig. 1 to 4, as an embodiment of the locking mechanism of the present invention, the sliding path is arc-shaped. Thus, the rod 4 slides more stably along the sliding groove 31.

Further, referring to fig. 1 to 4, as a specific embodiment of the locking mechanism of the present invention, the number of the sliding grooves 31 and the number of the rod bodies 4 are two, and the two sliding grooves 31 and the two rod bodies 4 correspond to each other one by one. So, two body of rod 4 and two spout 31's cooperation, handle 3 rotates more stably.

Further, referring to fig. 1 to 4, as an embodiment of the locking mechanism of the present invention, two rods 4 are respectively located at two opposite ends of the upper housing 12. In this way, the rod bodies 4 respectively located at the opposite ends of the upper case 12 can be more balanced when the handle 3 is rotated.

Further, referring to fig. 1 to 4, as a specific embodiment of the locking mechanism of the present invention, a reinforcing member 312 is disposed on the handle 3 outside the inlet 311, and two ends of the reinforcing member 312 are respectively connected to the handles 3 on two sides of the sliding groove 31. In this manner, the reinforcement 312 can reduce deformation at the entrance 311 of the chute 31.

Further, referring to fig. 1 to 4, as an embodiment of the locking mechanism of the present invention, a rib 313 is disposed at an edge of the sliding groove 31. Thus, the rib 313 can reduce deformation of the chute 31 itself.

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.
