Description

Technical Field

[0001] This utility model relates to the field of handcart tire technology, specifically a handcart tire that can prevent sideslip. Background Technology

[0002] Handcart tires are rubber products installed on handcart wheels to provide load-bearing and movement functions. The quality and performance of handcart tires are crucial to the safety, stability, and service life of handcarts.

[0003] According to a structurally stable handcart tire disclosed in the above application (Announcement No.: CN221562712U), when the connecting block rotates, it will cause the bottom of the clamping block to move downward. Since the right side of the limiting block is hinged to the surface of the fixed plate, when the bottom of the clamping block moves downward, it will cause the top of the clamping block to slide closer to the inside of the tire, and cause the limiting block to abut against the inside of the tire, thereby achieving a locking effect, improving the protection of personnel when using the handcart, and increasing the stability of the tire.

[0004] However, in actual use, the limiting block's contact with the tire for an extended period can cause the tire to shift, leading to sideslip. Therefore, we propose a trolley tire that can prevent sideslip. Utility Model Content

[0005] The purpose of this invention is to provide a handcart tire that can prevent sideslip, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a trolley tire with anti-slip capability, comprising a wheel body, a rotating rod sleeved inside the wheel body, and a limiting component provided on the outer surface of the rotating rod, the limiting component comprising:

[0007] A limiting ring is fixedly connected to the outer surface of a rotating rod. A fixed sleeve is threadedly connected to the outer surface of the rotating rod. A movable groove is provided on the side of the fixed sleeve, and a movable ring is rotatably connected inside the movable groove.

[0008] A connecting rod is hinged to the side of the movable ring, and a slider is hinged to the end of the connecting rod. A slot is provided on the side of the wheel body.

[0009] The pressing component is sleeved on the outer surface of the rotating rod. A sliding groove is provided on one side of the pressing component, and a locking block is fixedly connected to the other side of the pressing component. A rotating component is rotatably connected to the bottom of the inner wall of the sliding groove.

[0010] Preferably, the rotating component is composed of a threaded rod fixedly connected to the side of the rotating block, and the position of the rotating component corresponds to the center of the slide groove, which allows the rotating component to rotate well inside the slide groove.

[0011] Preferably, the slider is threadedly connected to the outer surface of the rotating component, and the slider is disposed inside the groove, which allows the slider to move when the rotating component rotates.

[0012] Preferably, the size of the card block corresponds to the position of the card slot, and the position of the card block corresponds to the position of the card slot, which allows the card block to be properly engaged inside the card slot.

[0013] Preferably, a lubrication assembly is provided on one side of the pressing member, the lubrication assembly includes an oil injection component, the oil injection component is fixedly connected to one side of the pressing member, and a guide component is fixedly connected to the other side of the pressing member.

[0014] Preferably, the upper surface of the oil injection component is provided with a limiting pin, and the interior of the oil injection component communicates with the interior of the guide component.

[0015] Compared with the prior art, this utility model provides a handcart tire that can prevent sideslip, which has the following beneficial effects:

[0016] 1. This anti-slip handcart tire, to prevent tire displacement during prolonged use, has the wheel body fitted onto the outer surface of the rotating rod, with the side of the wheel body contacting the limiting ring. Simultaneously, a pressing component is fitted onto the outer surface of the rotating rod, with a fixing sleeve contacting the end of the rotating rod. Rotating the fixing sleeve allows it to connect threadedly to the rotating rod, thus limiting its position. Simultaneously, rotating the pressing component aligns the position of the locking block with the locking groove. Rotating the rotating component moves the slider downwards, causing the connecting rod to move and simultaneously bringing the pressing component closer to the wheel body. After the pressing component contacts the wheel body, the locking block engages perfectly within the locking groove. This design allows the pressing component to push the wheel body for limiting its position while simultaneously allowing the pressing component to rotate along with the wheel body, preventing wheel displacement during use.

[0017] 2. This anti-slip handcart tire is designed to facilitate lubrication after prolonged use. After the wheel body has been in use for an extended period, the lubrication component is rotated upwards, and the limiting pin on the upper surface of the lubrication component is removed. Lubricating oil is then injected into the lubrication component, which transports the oil into the guide component. The guide component then guides the oil to accurately contact the bearing inside the wheel body for lubrication. Attached Figure Description

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a handcart tire with anti-slip capability, including a wheel body 1, a rotating rod 2 sleeved inside the wheel body 1, and a limiting component 3 provided on the outer surface of the rotating rod 2. The limiting component 3 includes a limiting ring 301, a fixing sleeve 302, a movable groove 303, a movable ring 304, a connecting rod 305, a slider 306, a slot 311, a pressing component 307, a sliding groove 308, a locking block 310, and a rotating component 309.

[0025] In this embodiment of the utility model, a limiting ring 301 is fixedly connected to the outer surface of the rotating rod 2. A fixed sleeve 302 is threadedly connected to the outer surface of the rotating rod 2. A movable groove 303 is provided on the side of the fixed sleeve 302. A movable ring 304 is rotatably connected inside the movable groove 303. A connecting rod 305 is hinged to the side of the movable ring 304. A slider 306 is hinged to the end of the connecting rod 305. The slider 306 is threadedly connected to the outer surface of the rotating part 309. The slider 306 is disposed inside the sliding groove 308, which allows the slider 306 to move when the rotating part 309 rotates. A slot 311 is provided on the side of the wheel body 1, and a pressing part... 307 is sleeved on the outer surface of the rotating rod 2. A sliding groove 308 is provided on one side of the pressing part 307, and a locking block 310 is fixedly connected to the other side of the pressing part 307. The size of the locking block 310 corresponds to the position of the locking groove 311, and the position of the locking block 310 corresponds to the position of the locking groove 311. This allows the locking block 310 to be well locked into the inside of the locking groove 311. A rotating part 309 is rotatably connected to the bottom of the inner wall of the sliding groove 308. The rotating part 309 is composed of a threaded rod fixedly connected to the side of the rotating block. The position of the rotating part 309 corresponds to the center of the sliding groove 308, which allows the rotating part 309 to rotate well inside the sliding groove 308.

[0026] Meanwhile, a lubrication assembly 4 is provided on one side of the pressing member 307. The lubrication assembly 4 includes an oil injection member 401, which is fixedly connected to one side of the pressing member 307. A limit pin is provided on the upper surface of the oil injection member 401. The interior of the oil injection member 401 communicates with the interior of the guide member 402. The guide member 402 is fixedly connected to the other side of the pressing member 307. In this way, after the wheel body 1 has been used for a long time, the oil injection member 401 can be rotated to the top, and the limit pin provided on the upper surface of the oil injection member 401 can be removed to inject lubricating oil into the interior of the oil injection member 401. Then, the oil is transported by the oil injection member 401 into the interior of the guide member 402. After being guided by the guide member 402, the oil can accurately contact the bearing inside the wheel body 1 for lubrication.

[0027] In this invention, during use, the wheel body 1 is fitted onto the outer surface of the rotating rod 2, so that the side of the wheel body 1 contacts the limiting ring 301. At the same time, the pressing member 307 is fitted onto the outer surface of the rotating rod 2, and the fixing sleeve 302 contacts the end of the rotating rod 2. The fixing sleeve 302 is rotated to make the fixing sleeve 302 threadedly connected to the rotating rod 2, thus limiting the fixing sleeve 302. Simultaneously, the pressing member 307 is rotated so that the position of the locking block 310 corresponds to the position of the locking groove 311. Then, the rotating member 309 is rotated so that the slider 306 moves downward, allowing the connecting rod 305 to move while the pressing member 307 moves closer to the wheel body 1. After the pressing member 307 contacts the wheel body 1, the locking block 310 just fits into the locking groove 311. This allows the pressing member 307 to push the wheel body 1 to limit its movement, and also allows the pressing member 307 to rotate together with the wheel body 1 when it rotates, thus preventing the wheel body 1 from shifting during use.

[0028] Furthermore, after the wheel body 1 has been used for a long time, the oil injection component 401 is rotated to the top, the limiting pin set on the upper surface of the oil injection component 401 is removed, and lubricating oil is injected into the oil injection component 401. The oil is then transported by the oil injection component 401 into the guide component 402. The guide component 402 then guides the oil to accurately contact the bearing inside the wheel body 1 for lubrication.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
