[0001] The utility model relates to the field of passenger car air duct inspection covers, in particular to a quick-detachable and quick-install inspection cover used in passenger cars. Background Art

[0002] Existing inspection covers for buses (such as air duct inspection doors) are available in flip and plug-in forms. In order to hide the fixing screws of the inspection covers, these two methods require pre-embedded bolts on the injection molded products. This method increases the thickness of the product, increases the difficulty in the molding process and increases the probability of shrinkage marks in the appearance. In addition, nuts need to be tightened during the subsequent installation process, which is inefficient. Utility Model Content

[0008] A plurality of third limit slots are provided on the left and right walls of the frame, and the third limit slots include a positioning slot and a clamping slot. The positioning slot runs through the top surface of the frame, and the left end of the clamping slot is connected to the positioning slot, and the positioning slot and the clamping slot form an L shape; a third limit block is provided on the cover plate corresponding to each third limit slot position, and the third limit block and the clamping slot are provided with a locking structure that cooperates with each other. The third limit block is inserted into the positioning slot from top to bottom and then inserted into the clamping slot to the right to realize the clamping connection between the third limit block and the third limit slot, and the third limit block is disengaged from the third limit slot when it moves in the opposite direction.

[0009] Furthermore, the top surface of the slot is partially concave to form a notch, and the top surface of the third limiting block is provided with a protrusion that matches the notch, and the protrusion and the notch cooperate to lock the third limiting block.

[0010] Furthermore, side panels are vertically extended downward from the four sides of the cover plate, and the side panels of the cover plate are arranged around the four sides of the frame to cover the sides of the frame. The first limit block and the second limit block are arranged on the inner side of the side panels, and the third limit block is connected to the inner top surface of the cover plate.

[0011] Furthermore, the frame includes a top plate and positioning edges extending vertically downward from the side walls around the inspection hole. The top plate is square, the inspection hole is set in the middle of the top plate, and screw mounting holes are provided on the top plate. The top plate is fixed above the air duct plate by screws in the screw mounting holes. The positioning edges are used to insert into the inspection opening opened on the air duct plate for positioning.

[0012] The utility model has the following beneficial effects:

[0022] like Figures 1 to 6 As shown, this embodiment discloses a quick-release and quick-install inspection cover for buses, comprising a frame body 1 and a cover body 2. An inspection hole 3 is provided in the middle of the frame body 1. Each edge of the frame body 1 is provided with a limiting groove. A matching limiting block is provided on the cover body 2 corresponding to each limiting groove position on the frame body 1. The length of the cover body is greater than the length of the frame body 1. The length direction of the cover body 2 is defined as the front-to-back direction. The cover body 2 covers the frame body 1 and moves backward so that each limiting block can be inserted into the corresponding limiting groove. The cover body 2 and the frame body 1 are buckled together through the cooperation of the limiting groove and the limiting block. The cover body 2 moves forward so that each limiting block can be disengaged from the corresponding limiting groove, thereby realizing the separation of the cover body 2 and the frame body 1.
