[0003] According to this operation requirement, maintenance personnel generally use conventional wrenches to operate the switch, but the structural characteristics of conventional wrenches make it difficult to reliably operate them in place in actual application. This makes the disassembly and maintenance of the damper actuator time-consuming and labor-intensive, which in turn affects the normal use of the combined air conditioning unit.

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0019] The utility model provides an embodiment of a combined air conditioner unit air valve actuator operating tool, specifically, Figure 1 As shown, it includes: a handle 1, a plate-shaped connecting arm 2 and a connecting head 3 for cooperating with the driving rod of the air valve actuator, wherein one end of the connecting arm 2 is connected to one end of the handle 1, and the connecting arm 2 and the handle 1 are at a right angle; the other end of the connecting arm 2 is connected to the connecting head 3. It can be understood that in order to facilitate the storage and use of the tool, the connecting arm 2 and the handle 1 can be detachably connected by screwing.

[0020] Also, a sleeve hole 31 is provided at the connector 3, and the sleeve hole 31 is used to be sleeved on the driving rod of the air valve actuator (it can be understood that a through hole can also be provided at the connection arm 2 where it is connected to the connector 3, and the present invention is not limited to this). In actual operation, the sleeve hole 31 can be directly designed to be in a shape that matches the driving rod, such as a square as shown in the figure; and further, in order to reliably apply a clamping force to the driving rod, an adjustable clamping block (not shown in the figure) is provided in the sleeve hole 31, and a top screw hole 32 is provided at the end of the connector 3, so that the position of the clamping block can be adjusted by screwing in the top screw so that it can be tightly held on the rod body of the driving rod. It can also be expanded to form a serration pattern on the working surface of the clamping block (i.e., the surface in contact with the driving rod) to further enhance the reliable and firm clamping force on the driving rod body.

[0021] Continuing from the above, when the above embodiments were actually tested, it was found that for some damper actuators with narrow installation space, further improvements can be made in terms of ease of use. To elaborate, in some preferred embodiments of the utility model, the connecting arm 2 is not limited to the straight arm shown in the figure, but can preferably adopt a curved arm shape with a bending structure; in addition, in other preferred embodiments, a preset angle is formed between the connecting head 3 and the connecting arm 2, that is, the connecting head 3 shown in the figure is in an "upward" state at a certain angle. All of the above improvements can be adapted to the operation of damper actuators in certain special positions.

[0022] Finally, it can be added that an anti-slip sleeve can be provided on the gripping portion of the handle 1 or a knurled surface can be formed to increase the gripping friction and facilitate the application of force to open and close the actuator.

[0023] In summary, the main design concept of the utility model is that it is mainly composed of a handle, a plate-shaped connecting arm and a connecting head for cooperating with the driving rod of the damper actuator. Specifically, one end of the connecting arm is connected to one end of the handle, and the connecting arm is at a right angle to the handle; the other end of the connecting arm is connected to the connecting head, and a sleeve hole is provided at the connecting head, and the sleeve hole is used to be sleeved on the driving rod of the damper actuator. Compared with conventional wrenches, the special tool provided by the utility model is better adapted to the operating space of the damper actuator, and can provide a better force application angle when operating the driving rod of the damper actuator, so that the adjustment operation of the damper actuator opening can be completed reliably and efficiently, thereby effectively ensuring the normal operation of the air-conditioning unit.
