Description of the Invention: [Technical Field] The present invention relates to a roller device, and more particularly to a roller device for a generator. [Prior Art] The fixed generator is placed on the ground and is not easy to move. In particular, the size and weight of the generator are very large. If the auxiliary moving mechanism is lacking and is directly transported by human power, it will inevitably cause difficulty in handling. Therefore, Some operators have designed a mobile generator to facilitate user handling. Referring to FIG. 1 , a conventional mobile generator 丨 has four push wheels 11 mounted on the bottom thereof (only three are drawn in view due to the viewing angle), so as to facilitate the user to apply the force to move, however, this design method However, it has the following disadvantages: (V) The generator 1 is not easily placed on the uneven ground: because the push wheel 11 is fixed to the bottom of the generator 1, and the ground is not flat The wheel u will form a rolling, and the generator i is not easily placed on the ground smoothly, and it is very easy to cause a sloshing phenomenon due to a slight touch. (2) The generator 1 is easy to slip: - ^ The push wheel U is There is no positioning function, so the user can easily push the generator i 疋 relatively well, and the friction between the ground and the ground is quite small, because the generator i is used in t because The external force pushes or shakes during operation, and the disc 1 Α ^ ^ 1 is more likely to fall off, causing electric shock and the like, causing sparks and sparking and causing fires and other accidents. 5 200800778 (3) The product of the generator 1 is relatively large: the push wheel U is located outside the bottom of the generator, so that in addition to the volume of the generator 1 itself, the push wheel η also occupies at the same time The space outside the motor 1 makes the mobile generator 1 phase master in the general fixed generator, and its product size is large. Therefore, how to overcome the above shortcomings will inevitably lead to the research direction of the two related industries. SUMMARY OF THE INVENTION Therefore, the object of the present invention is that the roller device of the coin-receiving generator not only facilitates the user to push the generator, but also the roller device can be in a stowed state to directly place the generator. It is not easy to produce slip on the ground. Thus, in the roller device of the generator of the present invention, the generator is housed in the frame. The roller device is disposed at the bottom of the frame, i includes a plurality of roller members that can roll along the ground, and a plurality of A connecting unit of each of the roller members and the frame is connected separately. Each of the coupling units has a sleeve member fixed to the frame and hollow inside, a shaft that passes through the sleeve member and is longitudinally movable inside thereof, and a fixing member that traverses the sleeve member The bottom end of the lifting shaft is fixed to the middle of the roller-roller member, and the fixing member is detachably contacting the material descending vehicle to position the lifting shaft in the sleeve member. The effect of the invention is that when the generator is to be pushed, the frame forms a space with the ground, and the roller member is protruded from the outside of the 卞/, #,~柩, and rolls along the ground to facilitate use. The generator is propelled, and when the fan is to be placed on the ground, the roller is placed in the frame, and the frame is placed directly on the ground. The roller member forms a multi-point branching action on the generator, thereby making the generator less prone to slipping. This design can be used to move the generator to an appropriate location for positioning. [Embodiment] The description of the details of the preferred embodiment of the present invention is set forth below with reference to the accompanying drawings. / gastric multi-view Figure 2 3 'The preferred embodiment of the roller device 2 of the generator 3 i of the present invention, the generator 31 (shown in Figure 3) is accommodated in a frame", the roller device 2 is divided into It is disposed at the bottom of the frame 32 and includes four roller members 21 which can be rolled along the ground, and four connecting units 22 for respectively connecting each of the rollers 32. The frame is convenient for explaining the generator. 31 and the frame 32, one of the corners, that is, one of the roller members 21 and the connection: the 兀 22 is on the 'four sides of the generator 31 are respectively provided with a mother roller member 21 and the coupling unit 22 Each of the connecting units 22 has a sleeve member 221 fixed to the frame 32, a lifting shaft 222 that is longitudinally movable inside the sleeve member 221, and a crossing shaft 横 μ μ α α 曰And a fixing member 223 detachably contacting the 222, and a head cover and a lowering axis 222 disposed at a top end of the lifting shaft 222 and contacting the outer edge of the sleeve member 221 The first elastic member (7) β* is prepared, and the material member 225, and a set of the second elastic member 226 disposed on the fixing member 223, In the embodiment, four of the cases are f, the first and second elastic members 225 7 200800778 , 226 are all a spring, and the sleeve member 221 is formed with a screw hole 227 which is movablely screwed. A bolt extending through the screw hole 227 is formed. The lifting shaft 222 is formed with a flat surface 228 ′ at the fixing member 223 and a protrusion adjacent to the bottom edge of the sleeve member 221 is formed adjacent to the bottom end. 229, the plane 228 is recessed inwardly to form a positioning slot 230. The head cover 224 and the protruding portion 229 cooperate to allow the lifting shaft 222 to be longitudinally moved within the sleeve member 221 by a set distance. The first elastic member 225 is respectively disposed on the outer bottom edge of the sleeve member 221 and the protruding portion 229 of the lifting shaft 222. The second elastic member 226 is sleeved on the fixing member 223 and located at the same. The outer side of the screw hole 227 and the two ends thereof respectively abut the fixing member 223 and the sleeve member 221. Each roller member 21 has a moving wheel 211 and an axle 212. The two ends of the wheel shaft 212 are respectively formed with threads. And simultaneously extending through the bottom end of the lifting shaft 222 and moving 211, the two nuts 213 are respectively screwed and locked at the two ends of the axle 212, so that one end of the axle 212 is locked at the bottom end of the lifting shaft 222, and the other end is pivotally mounted on the moving wheel 211. Thereby, the lifting shaft 222 and the roller member 21 are fixed together. Referring to Figures 3 and 4, when the generator 31 is to be pushed, the fixing member 223 is first formed from the screw hole 227 of the sleeve member 221. In a state of moderate release, the a defensive shaft 222 can be freely slid down in the sleeve member 221, and the user raises the generator 31 and the frame 32, and the sleeve member 221 moves upward accordingly. The lifting shaft 222 is moved downward by its own gravity and the elastic force of the first elastic member 225 until the head cover 224 comes into contact with the outer edge of the sleeve member 221 8 200800778. At this time, the lifting shaft 222 is not Then, the lowering is continued, and then the fixing member 223 is locked and inserted into the positioning groove 23, whereby the lifting shaft 222 is positioned in the sleeve member 221. The first elastic member 225 is formed into a moderately stretched state by its own elastic tension. The two ends of the first elastic member 225 are respectively abutted against the outer bottom edge of the sleeve member 221 and the protruding portion 229 of the lifting shaft 222. The 211 protrudes outside the frame 32 and rolls along the ground, and the frame 32 is formed with a space therebetween, so that the user can easily and conveniently use the moving wheel 211 of the roller member 21 to roll relative to the ground, thereby facilitating labor-saving. Further, the generator 31 is pushed. When the fixing member 223 is traversed through the sleeve member 221, the fixing member 223 and the sleeve member 221 may not be disposed by the second elastic member 226. The direct contact is generated, the wear is reduced, and the pressing force between the fixing member 223 and the lifting shaft 222 can also be adjusted, and the vibration of the generator 31 during operation can be effectively prevented, so that the fixing member 223 is formed. Loose. Referring to FIGS. 5 and 6, when the generator 31 is to be parked on the ground, the fixing member 223 is first appropriately loosened to be disengaged from the positioning groove 23〇. At this time, the generator 31 and the frame 32 are Will move downward due to its own weight, the sleeve member 221 will then move downward until the frame 32 is in direct contact with the ground, and the first elastic member 225 is the outer bottom of the sleeve member 221 The edge and the protruding portion 229 of the lifting shaft 222 are compressed, and an elastic restoring force is accumulated, even if the ground surface exhibits an uneven state as shown in FIG. 5, the elastic recovery force of the first elastic member 225 can be downward. Pushing up the protrusion 229 of the hoisting shaft 222, and automatically adjusting the lifting shaft 222 to the field position 'and then driving the moving wheel 211 to adjust its height with the height of the ground' automatically and smoothly placed on the ground. At this time, the fixing member 223 is locked to be pressed against the plane 228 of the lifting shaft 222. With this design, the moving wheel 211 is located in the frame 32 in the storage shape I', and the frame 32 is directly placed on the ground, and cooperates with the moving wheel 211 to form a multi-point support for the generator 31. The generator 31 can be placed on the ground smoothly, and it is not easy to cause slippage due to external force pushing or vibration during use. The present embodiment has the following advantages: (1) The generator 31 can maintain a good balance with the ground level: when the generator 31 is parked on the ground, even if The ground is in a state of ruggedness, and the height of the lifting shaft 222 can be adjusted by the elastic restoring force of the first elastic member 225 of each connecting unit 22, thereby driving the moving wheel 211 to adjust its height according to the height of the ground. The generator 31 is maintained in a fairly good balance as it is placed on the ground smoothly. (2) The roller device 2 can be mounted on the general generator 31 without affecting its product volume: since the roller device 2 is disposed on the frame 32 of the generator 31' and the roller device 2 is movable The ground device is housed in the frame, so the roller device 2 does not occupy the space outside the frame 32, and the overall product volume is increased. 200800778 (3) Pushing or locating the generator 31 can be operated by a single person. Since the four connecting units 22 are respectively disposed at the four corners of the generator 31, the user can change and adjust each of the connecting units 22 one by one. The height of the lifting shaft 222 is used to push or position the generator 31 without the help of others, thereby effectively improving work efficiency. (4) When the generator 31 is placed at a fixed position, slippage is less likely to occur:

Even if the external force pushes against the generator 31 or the generator 2 vibrates, it does not cause slippage. The generator shovel can be placed on the ground smoothly to improve its stability. + In summary, the roller device 2 of the generator 31 of the present invention can not only adjust the height of each moving wheel 211 with the height of the ground to maintain the balance state of the generator 31 as a whole, but can also be mounted on the general generator η. It does not affect the volume of its product, and a single person can push or position the generator 31' without the help of others, effectively improving the work efficiency. Moreover, when the hybrid generator 31 is parked on the ground, it is not easy to slip. Move, so it is enough to achieve the purpose of the present invention.
