[0030] Example

[0031] For ease of description, see Figure 1 As shown, the front and rear side walls of the locking member 5 along the X direction are respectively the first side wall and the second side wall, the side wall where the arc-shaped locking buckle 9 contacts the first side surface is the third side wall, and the side wall where the buckling body 6 contacts the second side surface is the fourth side wall; along the Y direction, the upper and lower side walls of the buckling body 6 are respectively the fifth side wall and the sixth side wall, and the clockwise and counterclockwise rotation of the buckling body 6 is based on looking straight at the fifth side wall; along the Z direction, the front and rear side walls of the buckling body 6 are respectively the seventh side wall and the eighth side wall.

[0032] A fast mechanical locking device for two shells, the locking device is used for fast buckling and locking between a first shell 1 and a second shell 2. The first shell 1 and the second shell 2 are both made of plastic material and can be integrally injection molded with an anchor 3, a positioning member 4 and a locking member 5. Figure 3 As shown, in this embodiment, the number of locking devices used to connect the first shell 1 and the second shell 2 is 2, and locking devices are installed on the two opposite side walls of the first shell 1 and the second shell 2. In other embodiments, the number of locking devices can be 3 or 4, and the specific number and installation position can be set according to actual conditions;

[0033] The locking device includes an anchor member 3, a positioning member 4, a locking member 5 and a buckling body 6. A handle 10 is provided on the side of the buckling body 6 away from the locking member 5. The handle 10 is used by the user to drive the buckling body 6 to rotate. The buckling body 6 and the handle 10 are integrally formed, and the buckling body 6 and the handle 10 are both made of plastic. The anchor member 3 and the positioning member 4 are both fixedly installed on the outer wall of the first shell 1. The distance between the anchor member 3 and the overlapping edge of the two shells is slightly closer than the distance between the positioning member 4 and the overlapping edge of the two shells. The anchor member 3 and the positioning member 4 both adopt a cylindrical structure. A limiting ring 11 for limiting the buckling body 6 is fixedly installed on the top of the anchor member 3; the locking member 5 is fixedly installed on the outer wall of the second shell 2 on the same side as the anchor member 3. The locking member 5 adopts a rectangular plate structure and is made of plastic. The locking member 5 is parallel to the overlapping edge of the two shells, and the buckling body 6 has a groove that is parallel to the anchor member 3. The rotating channel 7 is rotatably connected to the member 3, and the sliding channel 8 is slidably connected to the positioning member 4. The rotating channel 7 and the sliding channel 8 are hollow structures that penetrate the upper and lower surfaces of the buckling body 6. The sliding channel 8 adopts an arc-shaped channel with the anchor member 3 as the center and the distance between the anchor member 3 and the positioning member 4 as the radius. The difference between the inner diameter and the outer diameter of the sliding channel 8 is equal to the diameter of the locking member 5. An arc-shaped locking buckle 9 is fixedly installed on one side of the buckling body 6. The arc-shaped locking buckle 9 is integrally formed with the buckling body 6. The arc-shaped locking buckle 9 is made of plastic. One end of the arc-shaped locking buckle 9 is fixedly installed on the outer side wall of the buckling body 6. The other end of the arc-shaped locking buckle 9 is driven by the buckling body 6 to rotate and is connected to the side of the locking member 5 away from the anchor member 3, and the outer side wall of the buckling body 6 close to the locking member 5 is connected to the other side of the locking member 5. The outer side wall of the buckling body 6 close to the locking member 5 is a curved surface structure.

[0034] In this embodiment, when the buckle body 6 rotates counterclockwise so that the positioning member 4 is located at one end of the sliding channel 8 close to the fourth side wall, the third side wall of the arc-shaped locking buckle 9 and the first side wall of the locking member 5 are just in contact with each other, further limiting the rotation of the buckle body 6 and increasing the firmness of the fixed connection;

[0035] At the same time, in this embodiment, the handle 10 is bent in the Z-axis direction, which can make the center of gravity of the snapping body 6 approach the arc-shaped locking buckle 9, so that when the snapping body 6 and the locking member 5 are in a separated state, the fourth side wall is at an inclined angle, so that the locking member 5 can contact the fourth side wall to apply pressure at the first time when it needs to be locked.

[0036] Working principle: when a locking connection is required, firstly, the locking body 6 is pressed and sleeved on the anchoring member 3 through the rotating channel 7 on the locking body 6, so that the positioning member 4 is slidably connected with the sliding channel 8, and then the second housing 2 is moved closer to the first housing 1. After the second side wall of the locking member 5 contacts the fourth side wall of the locking body 6, a pressure in the X direction is generated, so that the locking body 6 rotates counterclockwise around the anchoring member 3, driving one end of the arc-shaped locking buckle 9 to rotate so that the third side wall of the arc-shaped locking buckle 9 contacts the first side wall of the locking member 5, that is, the connection locking position is reached;

[0037] When separation is required, the user holds the handle 10 to drive the buckling body 6 to rotate clockwise, so that the third side wall of the arc-shaped locking buckle 9 and the first side wall of the locking member 5 are separated, and at the same time, the contact point between the fourth side wall of the buckling body 6 and the second side wall of the locking member 5 moves in the opposite direction of the Z direction, and the distance between the contact point and the center of the anchor member 3 gradually increases, thereby gradually increasing the distance between the locking member 5 and the anchor member 3, which will generate a thrust in the opposite direction of the X direction to help the second shell 2 separate from the first shell 1. After separation, the second shell 2 can be removed.

[0038] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
