Abstract

The invention discloses a panel, a box body assembly and an air treatment unit, and relates to the technical field of air conditioning equipment, wherein the panel is provided with a plurality of counter bores for inserting screws, guide holes and a release stopping part for allowing the screws to pass through and applying sliding resistance to the screws, the inner diameter of the counter bores is matched with the maximum outer diameter of nuts of the screws, and the minimum aperture of the guide holes is matched with the outer diameter of the screws. Therefore, in the process of pushing the screw into the mounting hole of the panel, the counter bore can guide the screw cap, the guide hole guides the screw teeth, the screw teeth are prevented from being inclined to influence the alignment of the screw, and the assembly efficiency of the panel and the box body is improved. The anti-drop portion inhibits the screw from being separated from the mounting hole during the process of removing the screw. The panel and the screw after disassembly are constructed into a combined structure which is not easy to separate under the limit of the anti-falling part, the screw is still positioned in the mounting hole, the problem that the screw is easy to lose after disassembly can be solved, the panel and the screw can be assembled to be supplied, and the assembly efficiency of the production line is further improved.

Description

Panel, box subassembly and air handling unit Technical Field The invention relates to the technical field of air conditioning equipment, in particular to a panel, a box assembly and an air treatment unit. Background In the related art, the panel of the air handling unit is connected with the box body through screws. When the assembly line of mill is assembled, need the workman to hold pneumatic screwdriver with one's hand, hold the screw with one's hand, align the back with the mounting hole of panel with the screw, rethread pneumatic screwdriver is screwed down the screw. The assembly process is complex in operation, low in production efficiency and easy to drop. When installing or overhauling after sales, the workman need carry out the dismouting to the screw of panel, but because the installation space of air handling unit is narrow, installation environment is complicated, and the screw is small, takes place to fall behind the fall and is difficult to retrieve, need reinstallation, influences after sales efficiency. Disclosure of Invention The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the invention provides the panel, wherein the panel and the screw are constructed into a combined structure which is not easy to separate, so that the assembly efficiency of the panel and the box body can be improved, and the problem that the screw is easy to lose after being disassembled can be solved. The invention also provides a box assembly and an air treatment unit with the panel. According to the panel provided by the embodiment of the first aspect of the invention, the panel is arranged on a box body of an air treatment unit and comprises a plurality of mounting holes for inserting screws along a first direction, wherein the mounting holes comprise counter bores and guide holes which are communicated along the first direction, the aperture of each counter bore is matched with the maximum outer diameter of a nut of each screw, and the minimum aperture of each guide hole is matched with the outer diameter of a screw tooth of each screw; A thread-off prevention portion configured to allow the screw thread to pass therethrough in the first direction and to be able to provide the screw thread with a sliding resistance opposite to the first direction.
