Description

Technical Field

[0001] This utility model relates to the field of air conditioning component technology, and in particular to a control cover structure and its air conditioning unit. Background Technology

[0002] With the increasing demands for environmental control in modern buildings, central air conditioning systems, especially multi-split unit systems, are becoming increasingly widely used in large commercial facilities such as shopping malls. The outdoor air conditioning units of these systems are highly favored due to their high efficiency and flexible control characteristics. Outdoor units are typically equipped with control boxes for integrated management of the operation and maintenance of various components, ensuring the stable operation of the entire air conditioning system.

[0003] However, existing technologies have some design inconveniences. Specifically, the control box cover of most multi-split outdoor units is fastened with self-tapping screws. This design requires operators to loosen multiple screws to remove the panel when maintenance of wiring or components is needed, in order to access the control box for wiring installation, debugging, or troubleshooting. This frequent disassembly and installation not only increases the workload of workers, but also, after repeated tightening, the screws are prone to stripping, leading to insecure fixing or even malfunction, further impacting maintenance efficiency and user experience. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a control cover structure and its air conditioning unit, which solves the technical problem of inconvenient maintenance in the connection structure of existing control covers.

[0005] A control cover structure according to an embodiment of the present invention includes a hinge and a locking mechanism;

[0006] The control cover is hinged to the electrical control box body on one side, and a locking mechanism is used to connect the control cover to the electrical control box body on the other side.

[0007] The locking mechanism includes a fixed base installed on one side of the electrical control box body and a mounting plate installed on the fixed base. The mounting plate slides along the fixed base, and the sliding direction of the mounting plate is towards and away from the control cover. A limiting mechanism is provided between the mounting plate and the fixed base, and the limiting mechanism limits the closest distance between the mounting plate and the control cover.

[0008] An opening block is hinged to the mounting plate, and a locking block is hinged to the opening block. One end of the locking block is locked onto the control cover, and the other end of the locking block is locked onto the mounting plate.

[0009] The technical principle of this utility model is as follows: When disassembly is required, pull the opening block (rotate towards the control cover plate), so that the opening block drives the locking block to disengage from the mounting plate, that is, release the locking block from the mounting plate; then continue to pull the opening block to allow the locking block to disengage from the control cover plate, at which point the control cover plate can be opened, making it convenient for operators to maintain.

[0010] After completing the maintenance, first close the control cover, then lock the locking block onto the control cover, and then press down the opening block (rotate it away from the control cover) to lock the locking block back onto the mounting plate.

[0011] Compared with the prior art, this utility model has the following advantages: by using a fixed base, mounting plate, locking block and opening block to connect the electrical control box body and the control cover plate with a hinge, the technical problem of inconvenient maintenance of the connection structure of the existing control cover plate is solved.

[0012] Furthermore, the fixed base is provided with a guide rail, the mounting plate is inserted into the guide rail, the mounting plate slides along the guide rail, and the guide rail has an opening at the end away from the control cover plate, through which the mounting plate is inserted into the guide rail.

[0013] The guide rails allow the mounting plate to move along them, making it easier to install the mounting plate on the mounting base.

[0014] Furthermore, the limiting mechanism includes a limiting wall and a fixing clip. The limiting wall is disposed on both sides of the other end of the guide rail, and the fixing clip is disposed on one end of the mounting plate. The fixing clip extends out of the guide rail and is engaged with the end face of the fixing seat near the control cover plate.

[0015] The limiting wall and the limiting clip, together with the guide rail, restrict the mounting plate to the fixed seat. If disassembly is required, simply remove the limiting clip from the end face of the fixed seat and it can be moved out from the opening, making it convenient to assemble and disassemble the mounting plate from the fixed seat.

[0016] Furthermore, the guide rail includes two symmetrically arranged inverted L-shaped plates. A support seat is provided on one side of the mounting plate. The support seat is located between the two inverted L-shaped plates. A rotating shaft is provided on the support seat. The rotating shaft is hinged to the opening block between the two inverted L-shaped plates.

[0017] Ensure that the opening block can rotate around the pivot, while also ensuring the connection between the opening block and the mounting plate.

[0018] Furthermore, the locking block has a snap-in hook at one end near the control cover plate, and the control cover plate has a connecting block at the position corresponding to the locking block. The connecting block has a snap-in groove, and the snap-in hook snaps into the snap-in groove.

[0019] The locking mechanism, through the engagement of the hook and the locking groove, achieves the locking effect on the control cover.

[0020] Furthermore, the locking block has a fastening hook at the end away from the control cover plate, the mounting plate has a protrusion on the side away from the limiting mechanism, and the protrusion has a locking groove on the side away from the limiting mechanism, and the fastening hook is engaged in the locking groove.

[0021] The locking hook is designed to engage with the locking groove to ensure that the locking block can stably lock the control cover.

[0022] Furthermore, the locking block is provided with a clearance notch corresponding to the opening block, and a rotating shaft is provided inside the clearance notch. The opening block is installed inside the clearance notch, and the opening block is hinged to the rotating shaft.

[0023] This allows the opening block to rotate around the rotating shaft and also moves the locking block. By pulling the opening block, the control cover can be released from the locking block's lock.

[0024] Furthermore, two fixing clips are provided on one side of the opening block; one fixing clip is located at the end of the opening block near the control cover plate, and the fixing clip is hinged to the mounting plate; the other fixing clip is hinged to the locking block.

[0025] Ensure that the opening block can be stably hinged to the mounting plate and locking block.

[0026] Furthermore, the fixed clip has a C-shaped cross-section, and the opening block bends away from the control cover at one end towards the side away from the mounting plate.

[0027] The C-shaped structure makes it easy to snap into the rotating shaft, while the curved structure makes it easy for the operator to pull.

[0028] Furthermore, the fixing clip that is hinged to the mounting plate has a reinforcing rib on the side near the control cover plate.

[0029] Reinforcing ribs are added to increase the strength of the fixing clips located at the edges and prevent them from being damaged.

[0030] Furthermore, screws are installed on one side of the electrical control box body and one side of the control cover plate. The hinges are connected to the screws on both sides of the electrical control box body and the control cover plate, respectively, and nuts are provided on the screws to lock the hinges.

[0031] The hinge is fixed by a screw and a nut to form a stable hinge connection structure.

[0032] Furthermore, a fixing boss is provided between the hinge and the main body of the electrical control box and the control cover, and a mounting boss is provided between the fixing seat and the main body of the electrical control box.

[0033] Setting a fixed boss and installing a mounting boss can prevent the hinge and locking mechanism from directly acting on the electrical control box body and control cover, thus avoiding direct damage to the electrical control box body and control cover.

[0034] According to the embodiments of this utility model, the air conditioning unit has a receiving chamber on one side, a control cover structure is provided in the receiving chamber, the electrical control box body is installed in the receiving chamber, and the control cover covers the entire receiving chamber.

[0035] The air conditioning unit features a control box with a control cover, which facilitates maintenance. Attached Figure Description
