[0007] As a further improvement to the technical solution of this utility model, the upper part of the handle can be engaged with the bearing sleeve.
[0008] As a further improvement to the technical solution of this utility model, the handle can be folded 90 degrees.
[0009] As a further improvement to the technical solution of this utility model, the gear in the gear seat meshes with the gear in the control device.
[0010] As a further improvement to the technical solution of this utility model, the handle has two states: in the vertical state, the gear in the manual operating device is completely disengaged from the gear in the control device; in the 90-degree state, the gear in the manual operating device is engaged with the gear in the control device.

[0014] Figure 1 This is a schematic diagram of the overall structure of this utility model.
[0015] Figure 2 This is a schematic diagram of the structure of this utility model.
[0016] The attached diagram is labeled as follows: mounting base 1, gear 2, gear seat 3, spring 4, end cap 5, bearing 6, bearing sleeve 7, handle 8. Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] As attached Figure 1 and attached Figure 2 The manual operating device with isolation function shown includes a mounting base plate 1, a gear 2, a gear seat 3, a spring 4, an end cover 5, a bearing 6, a bearing sleeve 7, and a handle 8. The gear seat 3 is fixedly connected to the upper surface of the mounting base plate 1 by bolts. A set of gears 2 is placed in the inner cavity of the gear seat 3. The handle 8 is embedded in the gear seat 3. The bottom end of the handle 8 extends into the inner cavity of the mounting base plate 1 and is connected to the gear 2. A spring 4 is provided above the gear 2. A set of end covers 5 is adapted to be installed above the gear seat 3. A bearing 6 is provided at the connection between the gear seat 3 and the handle 8. A bearing sleeve 7 is provided above the bearing 6 and extends to the outside of the end cover 5.
[0019] like Figure 1As shown, the handle 8 has a folding structure and is divided into upper and lower parts. The upper and lower handles are hinged together by a pin. The bearing 6 and bearing sleeve 7 are adapted to the handle 8. The bearing 6 and bearing sleeve 7 play the role of guiding and fixing the handle 8 inside the device.
[0020] like Figure 1 As shown, the upper part of the handle 8 can be engaged with the bearing sleeve 7.
[0021] like Figure 1 As shown, handle 8 can be folded 90 degrees.
[0022] like Figure 1 As shown, gear 2 inside gear housing 3 meshes with gear in control equipment.
[0023] like Figure 1 As shown, the handle 8 has two states: in the vertical state, the gear 2 in the manual operating device is completely disengaged from the gear in the control device; in the 90-degree state, the gear 2 in the manual operating device is engaged with the gear in the control device.
[0024] Working principle of this utility model:
[0025] Gear 2 and spring 4 are mounted inside gear seat 2 via bearing sleeve 7 and connected to the manual operating handle. During normal automatic control of the equipment, the manual operating device, under the action of spring tension, keeps gear 2 in contact with the mounting base plate, isolating it from the control equipment (e.g., Figure 1 When manual operation is required, lift the handle 8 of the manual operating device upwards to retract the spring. At this time, the gear 2 inside the manual operating device meshes with the gear of the control device. Then, fold the handle 90 degrees, and the shaft of the handle 8 is locked onto the bearing sleeve 7 (e.g., Figure 2 Manual operation can be achieved by rotating handle 8 left and right. After operation, fold handle 8 90 degrees in the opposite direction, and the gear 2 in the manual operation device will be completely disengaged from the gear of the control device under the force of spring 4.
[0026] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
