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.

[0030] Please see Figure 1-7This utility model provides a technical solution: an RGV trolley that is easy to maintain, including a body 1 and wheels 2 disposed at the bottom of the body 1; a disassembly assembly 3 is provided at the bottom of the body 1, the disassembly assembly 3 includes a block 301, and the block 301 is slidably connected to the wheel 2, and a connecting block 302 is fixedly connected to the bottom of the body 1, the interior of the connecting block 302 is hollow, and a rack 305 is slidably connected inside the connecting block 302, and a gear 3 is meshed with the top of the rack 305. 04; wherein, a fixing plate 306 is symmetrically fixed to the bottom of the vehicle body 1, and threaded rods 307 are symmetrically fixed to both sides of the gear 304, and the side of the threaded rod 307 away from the gear 304 is rotatably connected to the fixing plate 306; wherein, a threaded sleeve 308 is sleeved on the outside of the threaded rod 307, and a moving rod 309 is fixedly connected to the top of the threaded sleeve 308, and the moving rod 309 is slidably connected to the fixing plate 306, and a moving plate 310 is slidably connected to one side of the moving rod 309, such as Figure 2 , 4 As shown, the wheel 2 is slid into the inside of the block 301, and then the rack 305 is pushed, so that the rack 305 drives the gear 304 to rotate. Then the gear 304 will simultaneously drive the threaded rods 307 on both sides to rotate, and the threads of the threaded rods 307 on both sides are opposite. This causes the threaded rods 307 on both sides to drive the threaded sleeves 308 on both sides to move towards each other. Then the threaded sleeves 308 will drive the moving rod 309 to move, and then the moving rod 309 will drive the moving plate 310 to move.

[0031] A card 311 is fixedly connected to one side of the movable plate 310, and a locking block 312 is rotatably connected to the front of the card 311. A coil spring 313 is provided at the pivot point between the locking block 312 and the card 311. The card 311 is slidably connected to the block 301. A sliding groove 314 is provided on one side of the wheel 2, and symmetrical locking grooves 315 are provided inside the wheel 2. The sliding groove 314 is located between the locking grooves 315. The top side of the wheel 2 and one side of the locking block 312 are both arc-shaped, and locking cylinders 316 slidably slide on the front of the wheel 2. Figure 3 , 6As shown, the movable plate 310 will drive the card 311 to move, and then the card 311 will enter the interior of the slide groove 314. Since the wheel 2 and one side of the locking block 312 are arc-shaped, the locking block 312 will rotate when it contacts one side of the wheel 2, so that it can smoothly enter the interior of the slide groove 314. When the locking block 312 enters the interior of the slide groove 314, the coil spring 313 will drive the locking block 312 to engage with the locking groove 315, thereby fixing the wheel 2. Secondly, when it is not necessary to fix the wheel 2, the locking cylinder 316 will hold the pivot of the locking block 312, and then the locking cylinder 316 will be rotated, thereby causing the locking block 312 to rotate out of the locking groove 315. Then the rack 305 can be pulled in the opposite direction. Moreover, the locking cylinder 316 can not only slide back and forth, but also slide left and right, and the locking block 312 is L-shaped.

[0032] A movable component 4 is provided on one side of the movable plate 310. The movable component 4 includes a mounting plate 403, and a spring 404 is fixedly connected to the top of the mounting plate 403.

A rectangular block 402 is fixedly connected inside the movable plate 310. A sliding groove 401 is provided on one side of the movable plate 310. A locking post 406 is fixedly connected to the top of the movable strip 405. Figure 4 As shown, pulling down the moving bar 405 compresses the spring 404, and at the same time, the moving bar 405 will drive the locking pin 406 to disengage from the inside of the rectangular block 402, thereby releasing the connection between the moving rod 309 and the moving plate 310. This means that the movement of the moving rod 309 will not drive the moving plate 310, so that it is possible to decide which position of the wheel 2 should not be removed as needed. The locking pin 406 is engaged with the rectangular block 402.

[0033] Working principle: Before using this easy-to-maintain RGV trolley, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 7As shown, when fixing the wheel 2 that needs repair, slide the wheel 2 into the inside of the block 301, then push the rack 305, causing the rack 305 to drive the gear 304 to rotate. The gear 304 will then simultaneously drive the threaded rods 307 on both sides to rotate, and the threads of the threaded rods 307 on both sides are opposite. This will cause the threaded rods 307 on both sides to drive the threaded sleeves 308 on both sides to move towards each other. Then the threaded sleeves 308 will drive the moving rod 309 to move, then the moving rod 309 will drive the moving plate 310 to move, then the moving plate 310 will drive the card 311 to move, and then the card 311 will enter the... Inside the slide groove 314, and because one side of the wheel 2 and the locking block 312 is arc-shaped, the locking block 312 will rotate when it contacts one side of the wheel 2, allowing it to smoothly enter the interior of the slide groove 314. When the locking block 312 enters the interior of the slide groove 314, the coil spring 313 will drive the locking block 312 to engage with the interior of the locking groove 315, thereby fixing the wheel 2. Secondly, when it is not necessary to fix the wheel 2, the locking cylinder 316 will hold the pivot of the locking block 312, and then the locking cylinder 316 will be rotated, causing the locking block 312 to rotate out of the interior of the locking groove 315, and then the rack 305 will be pulled in the opposite direction.

[0034] When some wheels 2 do not need to be replaced, the moving bar 405 can be pulled down to compress the spring 404. At the same time, the moving bar 405 will drive the locking pin 406 to disengage from the inside of the rectangular block 402, thereby detaching the connection between the moving rod 309 and the moving plate 310. This will prevent the moving rod 309 from moving the moving plate 310, allowing you to decide which wheel 2 position to leave unremoved as needed.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
