The upper cover comprises an upper shell 21, an upper side plate 22 and hanging nails 23, the upper side plate 22 is arranged on two sides of the upper shell 21, and the hanging nails 23 matched with the L-shaped grooves of the chassis base for use are mounted on the upper side plate.
An upper cover lock component 3 is also arranged on the upper cover, and the upper cover lock component 3 is a key structural member for realizing the firm fixation, the rapidness and the labor-saving assembly and disassembly of the upper cover of the case. As shown in fig. 4 to 11, the upper cover lock assembly includes a fixing housing 31, a press pin 32, an equilong rod 33, a long pin 35, a trigger 36, a locking key 37, a pressure spring 38, a pushing block 39 and a short pin 310,
the fixing shell 31 is used for fixing each upper cover lock part, and firmly fixing the upper cover lock component and the upper cover through riveting 4 convex points. The material can be sheet metal material SECC. The fixed shell is provided with two parallel pressing pins 32, a pushing block 39 is arranged below the pressing pins in a sliding fit mode, the two pressing pins are used for restraining the pushing block to enable the pushing block to only slide back and forth, and stainless steel can be selected as a material.
The pushing block 39 comprises a pushing block body, one end of the pushing block body is provided with a convex strip 391 for limiting the sliding distance of the pushing block, the bottom surface of the pushing block body is provided with two rotating columns 392, the two rotating columns are respectively hinged with a long equal-length rod 33, the middle of the long equal-length rod is provided with a hinge hole 34, the long equal-length rod is fixed with an upper cover sheet metal part through a rotating pin in the hinge hole, one end of the long equal-length rod is matched with the rotating column on the pushing block of the upper cover lock component and can rotate along with the rotating column, and the other end of the long equal-length rod transfers the rotating displacement to a square groove on the side surface of the top. The material can be sheet metal material SGCC.
Be provided with oval hinge hole 393 in one side that promotes the piece body, install the king pin 35 in the oval hinge hole, it is articulated mutually with the spanner piece through king pin 35 to promote the piece, promotes the piece and passes through the fixed formation revolute pair of king pin with the spanner piece, through pressing the round pin restraint, turns into the rotational displacement of spanner piece and linear displacement drives the equal stock motion. The material can be die-cast by zinc alloy.
The wrench block is further provided with a short pin 310, the wrench block is connected with the fixed shell through the short pin, and the short pin connects and fixes the wrench block and the fixed shell to form a revolute pair. The material can be stainless steel.
The pulling block is respectively connected with the fixed shell and the pushing block through a short pin and a long pin to form a revolute pair. The length of a force arm formed by the length from the pulling point of the wrench block to the short pin and the length between the long pin and the short pin is larger than the length of the force arm to realize the labor-saving function of the upper cover lock by taking the short pin as a fulcrum.
