Technical Field
[0001] This utility model relates to the technical field of small gasoline generator sets, and in particular to a small gasoline generator set that is easy to use. Background Technology
[0002] Traditional small gasoline generator sets typically employ a structural design that combines casters and locking devices. In motion, the casters enable convenient relocation, while the locking devices secure the casters in place during operation. A typical structure of this type of device includes a main frame, a gasoline generator set, bottom casters, and a locking mechanism. The casters are generally omnidirectional or directional casters, and the locking devices are often mechanical brakes or latching structures.
[0003] In applications such as outdoor operations, emergency power supply, and field exploration, such devices need to frequently switch between mobile and working states. However, existing technologies have significant drawbacks: when the device enters the working state, although the moving wheels are locked, they still remain in contact with the ground. The strong vibrations generated during unit operation are directly transmitted to the ground through the moving wheels. At the same time, the reverse impact force causes high-frequency impacts on the moving wheel bearings, hubs, and locking mechanisms, leading to accelerated wear of the moving wheels, increased risk of locking failure, and seriously affecting the service life and operational stability of the equipment.
[0004] Therefore, to address the issue of inconvenient switching between mobile and working states in scenarios requiring frequent transitions, a user-friendly small gasoline generator set can be designed. This generator set features a built-in support frame housing the main body, with two symmetrical support beams at the bottom. Each beam has damping shock absorbers and rubber support feet at both ends, and an integrated caster wheel switching mechanism. In mobile mode, the casters contact the ground, and the user pushes the support frame to move it. Once in the working area, the drive mechanism is activated to rotate the generator. The mechanism rotates 90 degrees, causing multiple sets of casters to retract upwards. At this time, multiple sets of rubber support feet contact the ground. The damping shock absorbers absorb vibrations during unit operation, achieving shock absorption and buffering. When the unit needs to be moved, the drive mechanism moves in the opposite direction, causing the rotating mechanism to rotate 90 degrees in the opposite direction, so that multiple sets of casters re-contact the ground. At this time, multiple sets of rubber support feet are off the ground. The key design is that the distance between the casters and the ground is greater than the distance between the rubber support feet and the ground, ensuring the correct contact sequence during switching. The device achieves convenient switching between mobile and working states by quickly switching between the casters and support feet, improving operational convenience. Utility Model Content
[0005] When the unit enters the working state, although the casters are locked, they still remain in contact with the ground. The strong vibrations generated during the unit's operation are directly transmitted to the ground through the casters. At the same time, the reverse impact force causes high-frequency impacts on the caster bearings, hubs, and locking mechanisms, leading to increased wear on the casters and a higher risk of locking failure. Therefore, in scenarios where frequent switching between the moving and working states is required, there is a problem of inconvenience in achieving convenient switching between the moving and working states.
[0006] The technical solution of this utility model is as follows: a small gasoline generator set that is easy to use, including a support frame, the main body of the gasoline generator set is set inside the support frame, and a support beam. The support beams are symmetrically and fixedly set on both sides of the bottom of the support frame. Each set of support beams is equipped with a damping shock absorber at both ends. Each set of damping shock absorbers is equipped with a rubber support foot at the bottom. Each set of support beams is rotatably equipped with a universal wheel at both ends. A rotating mechanism is rotatably set inside each set of support beams. A drive mechanism and a guide mechanism are set between two sets of support beams. Multiple sets of rubber support feet and multiple sets of universal wheels are respectively set at the four corners of the bottom of the support frame.
[0007] Preferably, when using this easy-to-use small gasoline generator set, the generator set has a built-in gasoline generator set body through a support frame, with two sets of symmetrical support beams at the bottom. Each beam has damping shock absorbers and rubber support feet at both ends, and integrates a universal wheel switching mechanism. In the moving state, the universal wheels are in contact with the ground. The user pushes the support frame to move it. After reaching the working area, the drive mechanism is activated to rotate the rotating mechanism 90 degrees, causing multiple sets of universal wheels to retract upwards. At this time, multiple sets of rubber support feet are in contact with the ground. The damping shock absorbers absorb vibrations when the unit is working, achieving shock absorption and buffering. When it is necessary to move the unit, the drive mechanism moves in the opposite direction, causing the rotating mechanism to rotate in the opposite direction by 90 degrees, so that multiple sets of universal wheels are in contact with the ground again. At this time, multiple sets of rubber support feet are off the ground. The key design is that the distance between the universal wheels and the ground is greater than the distance between the rubber support feet and the ground, ensuring the correct contact sequence during switching. The device realizes convenient conversion between the moving state and the working state by quickly switching the universal wheels and support feet, improving the ease of operation.
[0008] Preferably, the rotating mechanism includes a rotating shaft and support blocks. Support blocks are symmetrically and fixedly installed on both sides of the inner cavity of each set of support beams, and a rotating shaft is rotatably installed between the two sets of support blocks.
[0009] Preferably, the rotating mechanism also includes connecting parts, with connecting parts fixedly sleeved on both ends of each set of rotating shafts, and each set of connecting parts fixedly connected to the universal wheel on the same side.
[0010] Preferably, the guiding mechanism includes a fixed frame and a guide slide rod. The fixed frame is fixedly installed on the outer side of both sets of supporting beams, and the guide slide rod is fixedly installed between the two sets of fixed frames. The guide slide rod passes through the space between the two sets of supporting beams.
[0011] Preferably, the drive mechanism includes a rotating gear, a guide tooth plate, and a connecting side plate. The guide tooth plates are slidably sleeved on both sides of the guide slide rod. A connecting side plate is fixedly installed between the two sets of guide tooth plates. A rotating gear is fixedly installed on the middle side wall of each set of rotating shafts. Each set of rotating gears meshes with the guide tooth plate on the same side. The guide tooth plate passes through and is slidably installed inside the support beam.
[0012] Preferably, the drive mechanism also includes an electrically controlled telescopic rod and a fixed rod. The electrically controlled telescopic rod is fixedly installed between the two sets of support beams, and the fixed rod is fixedly installed at the telescopic end of the electrically controlled telescopic rod. The upper end of the fixed rod is fixedly connected to the end of the connecting side plate.
[0013] Preferably, handrails are symmetrically and rotatably installed on one side of the outer wall of the support frame, and the ends of each set of handrails are hinged to the outer wall of the support frame.
[0014] The beneficial effects of this utility model are:
[0015] 1. When using this easy-to-use small gasoline generator set, the generator set has a built-in gasoline generator body through a support frame. Two sets of symmetrical support beams are set at the bottom. Each beam is equipped with a damping shock absorber and rubber support feet at both ends, and integrates a universal wheel switching mechanism. In the moving state, the universal wheels are in contact with the ground. The user pushes the support frame to move. After reaching the working area, the drive mechanism is activated to drive the rotating mechanism to rotate 90 degrees, and drives the multiple sets of universal wheels to retract upwards. At this time, the multiple sets of rubber support feet are in contact with the ground. The damping shock absorbers absorb vibrations when the unit is working, realizing shock absorption. When it is necessary to move the unit, the drive mechanism moves in the opposite direction, driving the rotating mechanism to rotate 90 degrees in the opposite direction, so that the multiple sets of universal wheels are in contact with the ground again. At this time, the multiple sets of rubber support feet are off the ground. The key design is that the distance between the universal wheels and the ground is greater than the distance between the rubber support feet and the ground, ensuring the correct contact sequence during switching. The device realizes convenient conversion between the moving state and the working state by quickly switching the universal wheels and support feet, improving the ease of operation.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] Please see Figure 1 and Figure 3This utility model provides an embodiment: a small gasoline generator set that is easy to use, including a support frame 1, a gasoline generator set body 2 is arranged inside the support frame 1, and a support beam 3. The support beams 3 are symmetrically and fixedly arranged on both sides of the bottom of the support frame 1. Each set of support beams 3 is provided with damping shock absorbers 4 at both ends. Each set of damping shock absorbers 4 is provided with rubber support feet 5 at the bottom. Each set of support beams 3 is rotatably provided with universal wheels 6 at both ends. Each set of support beams 3 is rotatably provided with a rotating mechanism inside. A driving mechanism and a guiding mechanism are arranged between two sets of support beams 3. Multiple sets of rubber support feet 5 and multiple sets of universal wheels 6 are respectively arranged at the four corners of the bottom of the support frame 1.
[0027] Please see Figure 2 and Figure 3 The rotating mechanism includes a rotating shaft 7 and a support block 8. The support blocks 8 are symmetrically and fixedly installed on both sides of the inner cavity of each set of support beams 3. The rotating shaft 7 is rotatably installed between the two sets of support blocks 8. The rotating shaft 7 is fixed inside the beam through the support block 8 to ensure structural strength. The rotating mechanism also includes a connector 9. The connector 9 is fixedly sleeved on both ends of each set of rotating shafts 7. Each set of connectors 9 is fixedly connected to the universal wheel 6 on the same side. When the rotating shaft 7 rotates 90 degrees, the universal wheel 6 is retracted upwards through the connector 9.
[0028] Please see Figure 4 and Figure 5 The guiding mechanism includes a fixed frame 10 and a guide slide rod 11. Fixed frames 10 are fixedly installed on the outer sides of both sets of supporting beams 3. A guide slide rod 11 is fixedly installed between the two sets of fixed frames 10, passing through the two sets of supporting beams 3. The guide slide rod 11 serves as a sliding guide. The driving mechanism includes a rotating gear 12, a guide tooth plate 13, and a connecting side plate 14. Guide tooth plates 13 are slidably fitted onto the side walls at both ends of the guide slide rod 11. A connecting side plate 14 is fixedly installed between the two sets of guide tooth plates 13. A rotating gear 12 is fixedly installed on the middle side wall of each set of rotating shafts 7. Each set of rotating gears 12 is respectively connected to the guide tooth plate 14 on the same side. 3. Engagement: The guide tooth plate 13 passes through and slides inside the support beam 3. When the guide tooth plate 13 slides in the opposite direction, it drives the rotating shaft 7 to rotate 90 degrees in the opposite direction. The caster wheel 6 re-contacts the ground, and the rubber support foot 5 leaves the ground. The drive mechanism also includes an electrically controlled telescopic rod 15 and a fixed rod 16. The electrically controlled telescopic rod 15 is fixedly installed between the two sets of support beams 3. The fixed rod 16 is fixedly installed at the telescopic end of the electrically controlled telescopic rod 15. The upper end of the fixed rod 16 is fixedly connected to the end of the connecting side plate 14. When the electrically controlled telescopic rod 15 is activated, it pushes the fixed rod 16 to drive the connecting side plate 14 to move horizontally. The connecting side plate 14 drives the guide tooth plates 13 on both sides to slide synchronously along the guide slide rod 11.
[0029] Please see Figure 1 and Figure 2The support frame 1 has symmetrical and rotatable handrails 17 on one side of its outer wall. The ends of each handrail 17 are hinged to the outer wall of the support frame 1. The hinged design of the handrail 17 allows for folding and storage, reducing storage space occupation.
[0030] When using this easy-to-use small gasoline generator set, the working principle of this easy-to-use small gasoline generator set is as follows: The generator set has a gasoline generator set body 2 built into a support frame 1, and two sets of symmetrical support beams 3 are set at the bottom. Each side beam is equipped with a damping shock absorber 4 and a rubber support foot 5 at both ends, and integrates a universal wheel 6 switching mechanism.
[0031] When in motion, the casters 6 are in contact with the ground. The user pushes the unit to move via the hinged handle 17. After reaching the working area, the electrically controlled telescopic rod 15 is activated, pushing the fixed rod 16 to move the connecting side plate 14 horizontally. The connecting side plate 14 drives the guide tooth plates 13 on both sides to slide synchronously along the guide slide rod 11. Since the guide tooth plates 13 mesh with the rotating gear 12, the rotating shaft 7 is rotated 90 degrees. The casters 6 are retracted upwards through the connecting piece 9. At this time, multiple sets of rubber support feet 5 are in contact with the ground. The damping shock absorber 4 absorbs vibration when the unit is working, achieving shock absorption and buffering.
[0032] When the unit needs to be moved, the electrically controlled telescopic rod 15 moves in the reverse direction, the guide tooth plate 13 slides in the reverse direction, driving the rotating shaft 7 to rotate 90 degrees in the reverse direction, and multiple sets of universal wheels 6 re-contact the ground. At the same time, multiple sets of rubber support feet 5 are lifted off the ground. The key design is that the distance between the universal wheels 6 and the ground is greater than the distance between the rubber support feet 5 and the ground, ensuring the correct contact sequence during switching. The electrical control system is linked with the electrically controlled telescopic rod 15 to achieve automated control. The guide slide rod 11 and the guide tooth plate 13 cooperate to ensure the smoothness of movement. The rotating shaft 7 is fixed inside the crossbeam by the support block 8 to ensure structural strength.
[0033] The device first achieves convenient switching between mobile and working states by electrically controlling the omnidirectional wheel 6 to quickly switch between the support feet, thus improving operational convenience.
[0034] Secondly, the combined design of the damping shock absorber 4 and the rubber support foot 5 effectively reduces the vibration transmission during unit operation, and improves the stability and service life of the equipment.
[0035] Furthermore, the omnidirectional wheel 6 retraction mechanism adopts a gear and rack transmission, combined with the linear guidance of the guide slide rod 11, to ensure precise and controllable movement trajectory and avoid the risk of jamming or deviation.
[0036] In addition, the 17-hinge connection design of the handrail allows for folding and storage, reducing storage space occupation. Finally, the electrical control system is integrated with the unit's electrical control unit, realizing intelligent control. Users can switch states with simple operations, lowering the threshold for use.
[0037] These design features work together to significantly improve the portability, stability, and ease of operation of the unit while ensuring its basic power generation function. It is particularly suitable for outdoor operations and emergency power supply scenarios that require frequent relocation and deployment, effectively solving the problems of traditional small generator sets such as inconvenience in movement, poor vibration damping when stationary, and complex operation.
[0038] Through the above steps, when using this easy-to-use small gasoline generator set, the generator set has a built-in gasoline generator set body 2 through a support frame 1, and two sets of symmetrical support beams 3 are set at the bottom. Each side beam is equipped with damping shock absorbers 4 and rubber support feet 5 at both ends, and integrates a universal wheel 6 switching mechanism. In the moving state, the universal wheels 6 are in contact with the ground. The user pushes the support frame 1 to move. After reaching the working area, the drive mechanism is activated to drive the rotating mechanism to rotate 90 degrees, and drive the multiple sets of universal wheels 6 to retract upwards. At this time, the multiple sets of rubber support feet 5 are in contact with the ground. The damping shock absorbers 4 absorb vibration when the unit is working, realizing shock absorption and buffering. When it is necessary to move the unit, the drive mechanism moves in the opposite direction, driving the rotating mechanism to rotate 90 degrees in the opposite direction, so that the multiple sets of universal wheels 6 are in contact with the ground again. At this time, the multiple sets of rubber support feet 5 are off the ground. The key design is that the distance between the universal wheels 6 and the ground is greater than the distance between the rubber support feet 5 and the ground, ensuring the correct contact sequence during switching. The device realizes convenient conversion between the moving state and the working state by quickly switching the universal wheels 6 and the support feet, improving the convenience of operation.
[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
