[0002] Mobile generators, also known as emergency power vehicles, are mobile power supply equipment formed by installing generator sets and control systems on a dedicated vehicle chassis or a convenient mobile platform. They can provide flexible and efficient power support for temporary or emergency power needs. With the increasing demand for flexibility and emergency power supply in modern society, mobile generators are playing an increasingly important role in various temporary power supply scenarios, field operations, and responding to sudden power outages.
[0003] Small and medium-sized mobile generators are widely used in emergency power supply in the field due to their lightweight and compact structure, which allows them to be moved manually. When the generator is in operation, it is necessary to fix and support it to ensure stable operation.

[0032] Working principle or structural principle:
[0033] The generator car body 1 is moved by a vehicle and manually towed. During installation, the generator car body 1 is moved to a relatively flat surface. Then, with the generator car body 1 tilted upwards, the drive lever 6 is held and pulled down. During operation, the upper part of the drive lever 6 is held by hand, and the unlocking pin 13 is pressed down by the fingers. The pressing down of the unlocking pin 13 causes the limiting latch 12 to move down and disengage from the slot of the limiting latch 16. Then, the drive lever 6 is flipped and pulled to rotate the mounting leg 3 ninety degrees, placing it in the position shown in the attached figure. Figure 1In the working state shown, the drive cable 5 is pulled by the rotation of the cable mounting wheel 4 to move the two sets of limiting slot blocks 9 forward synchronously. During the process, the limiting tooth groove 11 in the middle of the limiting slot block 9 engages with the tooth groove at the wheel axle end of the generator car body 1, thereby locking and limiting the two sets of wheels at the rear of the generator car body 1. After flipping into place, the limiting clamp head 12 on the rear side of the drive rod 6 engages and locks with the limiting clamp seat 16 on the lower side of the generator car body 1, completing the flipping and locking of the drive rod 6. Then, the mounting leg 3 is supported on the upper part of the ground. The limiting slot block 9 and the mounting leg 3 cooperate to form a double anti-movement limiting structure, which has better limiting support stability than the traditional single-leg limiting structure, thus completing the working support and fixation of the generator car body 1.
[0034] In summary, this fixing device adopts a double-locking working structure. Addressing the fixing and support requirements of small, manually-driven generator vehicles, it adds a wheel locking structure to the existing outrigger support structure. A limiting block 9 is mounted on the inner side of the rear wheel of the generator vehicle body 1 via a mounting seat 7. The limiting block 9 is driven to the support shaft 2 in the middle of the mounting leg 3 via a drive cable 5. After the mounting leg 3 is deployed, the locking of the rear wheel of the generator vehicle body 1 by the limiting block 9 engages with the inner side of the wheel shaft achieves a working lock. Together with the mounting leg 3, this forms a double-locking anti-movement structure, which offers better limiting support stability compared to the traditional single-leg limiting structure, thus facilitating… The improved stability and safety of the generator car body 1 are achieved by adopting a rod-type support drive structure. A drive rod 6 is installed at the end of the support column 2 of the mounting leg 3. The rotation of the drive rod 6 enables the mounting leg 3 and the limiting slot block 9 to move synchronously. The generator car body 1 can be fixedly supported and moved and unlocked with a simple pulling and rotating operation, which is convenient and quick. The drive rod 6 is limited and locked by the engagement between the limiting clip head 12 and the limiting clip seat 16.
