Technical Field

[0001] The utility model relates to the field of trolleys, in particular to a trolley tire with a special track. Background Art

[0002] A handcart is a transport vehicle that can be pushed or pulled by humans, and it is the ancestor of all vehicles. Although handcart material handling technology continues to advance, handcarts remain an indispensable tool for transporting materials. Handcarts are widely used in production and daily life because they are low-cost, easy to maintain, convenient to operate, and lightweight. They can be used in places where motor vehicles are inconvenient, and are very convenient for transporting light items over short distances.

[0003] The existing trolley needs to be pushed and worked according to the track guide. The existing tires cannot meet the requirements of stable travel on the special track. Therefore, it is necessary to change the trolley tire structure so that the trolley can move steadily on the special track. Summary of the Invention

[0004] The utility model aims to provide a wheelbarrow tire with a special track, so as to solve the problem that the existing wheelbarrow tire cannot move stably on the special track.

[0005] To address the above-mentioned problems, a special track trolley tire is provided, including a track for use with the same, wherein the top of the track is provided with a guide strip, and at least two sets of grooves are provided on both sides of the track. The tire is characterized in that it includes a protective shell, an A-axle, a B-axle, and a tire, and the top of the dust cover is provided with a mounting hole, and the mounting hole is used to connect the trolley's rotating shaft. The dust cover is provided with an A-axle and a B-axle at both ends, respectively, and the A-axle and the B-axle respectively pass through the side wall of the dust cover. The B-axle is provided with an external thread structure at one end within the dust cover cavity, and the A-axle is provided with an internal thread structure for use with the thread structure near the end of the B-axle, and the A-axle and the B-axle thread structures are connected to each other. The tire is provided in the dust cover cavity, and the A-axle and the B-axle respectively pass through the tire. A bearing A is provided between the A-axle and the inner side wall of the tire cavity, and a bearing B is provided between the B-axle and the inner side wall of the tire cavity. The A and B bearings can support the tire to rotate about the A and B-axles as the axis.

[0006] Preferably, a track groove is provided on the outer surface of the tire for use in conjunction with the upper surface of the track.

[0007] Preferably, the outer surfaces on both sides of the dust cover are bolted with at least two groups of connecting arms, and the connecting arms are integrally cast with a pillar near the position of the track groove. A guide wheel is provided on one end of the pillar near the groove, and the guide wheel is penetrated by a guide pin and the guide pin is bolted to the top of the pillar.

[0008] Preferably, the guide wheel installation position needs to ensure that the upper surface of the guide wheel is close to the upper surface of the groove in the track.

[0009] Preferably, the dust cover, connecting arm and support are all made of hard metal to ensure strength.

[0010] Preferably, the outer surface of the tire is covered with rubber material depending on the working environment.

[0011] In summary, the beneficial effects of the present invention are:

[0012] The utility model can ensure stability when working on the track by adding a mechanical tire. When the tire rotates, it rotates along the guide strip. The addition of connecting arms, pillars, guide pins and guide wheels avoids deviation or rollover when the tire moves. When the tire as a whole rolls over or deviates, the upper surface of the guide wheel will be tightly attached to and engaged in the groove of the track, so that the tire as a whole ensures that the track groove and the guide strip are consistent, thereby avoiding tire derailment.

[0022] See also Figure 1-4 As shown, it includes a protective shell, axle A 121, axle B 123, and a tire 131. A mounting hole 112 is provided at the top of the dust cover 111 for connecting to the rotating shaft of the cart. Axle A 121 and axle B 123 are provided at both ends of the dust cover 111, respectively. Axle A 121 and axle B 123 extend through the side walls of the dust cover 111. Axle B 123 has an external thread structure at one end within the cavity of the dust cover 111, and an internal thread structure is provided on the end of axle A 121 near axle B 123 for use with the thread structure. The A wheel axle 121 and the B wheel axle 123 are connected to each other by threaded structures, and the tire 131 is set in the cavity of the dust cover 111. The A wheel axle 121 and the B wheel axle 123 respectively pass through the tire 131. An A bearing 122 is set between the A wheel axle 121 and the inner side wall of the tire 131 cavity, and a B bearing 124 is set between the B wheel axle 123 and the inner side wall of the tire 131 cavity.
