As an example, the existing R base station air conditioner mainly consists of an upper half (mainly including an evaporator component and a motor bracket component) and a lower half (mainly including an electrical box and a compressor component). The lower half part of the three-phase internal machine relates to core parts such as a compressor, an electrical box part and the like, and is used as a key investigation object in daily inspection and after-sale maintenance. In order to facilitate the inspection and maintenance of workers, the panel 80 is disassembled into the upper panel 80 and the lower panel 80, but the maintenance efficiency is still affected by the fact that the lower panel 80 is opened by disassembling screws at present.

This technical scheme provides one kind and does not need to dismantle the screw, and the realization that can be swift is panel 80 goes up and down to open transmission, improves maintenance efficiency after sale greatly, and this transmission's actuating lever supports between the curb plate about simultaneously, prevents to control curb plate indent deformation, improves complete machine intensity.

The technical problems solved by the invention are as follows:

2. the strength of the whole machine is improved: the driving rod in the middle of the transmission mechanism not only drives the moving plate on the other side to rotate, but also bears the function of the framework, and the driving rod is supported between the left side plate and the right side plate to prevent the left side plate and the right side plate from being inwards concave and deformed.

Has the advantages that:

by using the transmission device, the lifting and opening of the lower panel 80 can be realized more quickly, the after-sale maintenance efficiency is improved, and meanwhile, the driving rod in the middle of the movement device bears the skeleton function so as to improve the strength of the whole machine.

This scheme has provided one kind can swiftly realize down panel 80 goes up and down the transmission of opening, need not dismantle the screw and dismantle panel 80 down, and this transmission can accomplish with opening along with closing with the help of the magnet. Meanwhile, a driving rod of the transmission device is supported between the left side plate and the right side plate, so that the left side plate and the right side plate are prevented from being inwards concave and deformed, and the strength of the whole machine is improved.

The model of the whole machine of the R cabinet machine is shown in figures 6-8, the whole machine is divided into an upper half part and a lower half part, wherein the lower half part is a compressor and an electrical box component. The electrical apparatus box and the core drive spare part of compressor that lower panel 80 covers (protects) the lower extreme, in order to open panel 80 and check and maintain down, this proposal provides the device that can swiftly open panel 80 down, and the concrete implementation mode is: the inner sides of the left side plate and the right side plate (equivalent to the fixed part 20) are respectively provided with two mechanisms (equivalent to the transmission assembly 50) to form a whole transmission device, the transmission device consists of a moving plate (equivalent to the supporting part 10), a track fixing plate (equivalent to the fixed part 20), a swinging connecting rod (equivalent to the connecting rod assembly 30) and a driving rod (equivalent to the transmission rod 60), when the lower panel 80 needs to be opened, the internal transmission device is driven by a manual rocker (equivalent to a hand wheel 41) shown in fig. 8, after the manual remote lever is rocked, the other end (shown in fig. 3) connected with the manual rocker drives the swinging connecting rod to rotate, the moving plate fixed together with the tail end of the swinging connecting rod moves along the limited track (equivalent to the first slide way 21 and the second slide way 22) of the track fixing plate, and simultaneously drives the driving rod fixed together with the moving plate and the tail end of the connecting rod to move, and the driving rod drives the driven moving plate on the other side to move, as shown in fig. 3, so that the moving plates on both sides move upwards (equivalent to the first state) and the lower panel 80 fixed together with the upper end of the moving plate is in the first state; after reaching the limit position (corresponding to the first end 221 of the second slideway 22) for limiting the upward movement of the moving plate, the moving plate starts to rotate along the arc track (corresponding to the first slideway 21), and at this time, the lower panel 80 starts to rotate to realize the opening mode (as shown in fig. 7 and 8); when the lower panel 80 needs to be closed, the manual remote lever is directly swung in the opposite direction, and at this time, the lower panel 80 is restored to the original closed state, and at the same time, the stable closed state is realized due to the magnets (as shown in fig. 8) on both sides.

At the same time, a self-locking state is realized at the end position (end point 1 position):

as shown in fig. 2, the position of the end point 1 tends to slide downwards due to the gravity G, so that G is decomposed into mutually perpendicular forces G1 (tangential to the arc track) and G2, resulting in that the end point 2 receives the force from G2, and in addition, the downward gravity G of the end point 2 itself causes the end point 2 (corresponding to the fourth hinge point) to have a tendency to rotate clockwise around the end point 3 (fixed, corresponding to the second hinge point), and since the end point 1 (corresponding to the third hinge point) is at the extreme position as shown in the figure, the rotation of the end point 2 is limited, so that the end point 1 is in a static state of stress balance. G is decomposed into force G1 which is tangent to the arc track 1 (equivalent to the first slideway 21) so that the end point 1 has the tendency of moving along the arc track 1 (equivalent to the first slideway 21), but because the rod 1 (equivalent to the first connecting rod 33) and the limit of the end point 2 which is in a stress balance static state at the moment, the actual end point 1 can only rotate along the arc track 2 by taking the end point 2 as the center of a circle and taking the rod 1 as the radius, the second limit groove (arc groove, equivalent to the first slideway 21) can limit the rotation of the second limit groove and provide a balance force for offsetting the rotation of the second limit groove, and the end point 1 is also in a static state at the moment to realize self-locking.

The scheme provides a transmission mechanism capable of quickly realizing lifting opening of the lower panel 80, the screw and the lower panel 80 do not need to be disassembled, only the movement mechanism is utilized, opening and closing can be realized along with opening, and the after-sale maintenance efficiency is improved. Meanwhile, a driving rod of the transmission mechanism is supported between the left side plate and the right side plate, so that the left side plate and the right side plate are prevented from being inwards concave and deformed, and the strength of the whole machine is improved.
