Description

Technical Field

[0001] This utility model relates to the field of support wheel technology, specifically a support wheel with an auxiliary pressure-dividing structure. Background Technology

[0002] Trailer jacks, also known as support wheels, hand-cranked jacks, or single-wheel trailer jacks, are a type of jack that uses a rigid lifting component as its working device. The support wheels assist in the placement and movement of vehicles. The main functions of the support wheels are to provide stability, assist in movement, reduce load, provide flexible steering, and protect the ground.

[0003] When using existing support wheels, because the support wheels need to support the equipment and bear a heavy weight, the pressure on the individual moving wheels at the bottom is too high, which can easily lead to damage to the moving wheels during support, making it inconvenient for the support wheels to bear pressure during use. Utility Model Content

[0004] The purpose of this invention is to provide a support wheel with an auxiliary pressure-dividing structure to solve the problem mentioned in the background art that the support wheel is not easy to assist in pressure division.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support wheel with an auxiliary pressure-dividing structure, comprising an adjusting sleeve rod, a handle, an adjusting seat, and a support wheel body. A handle is provided on one side of the adjusting sleeve rod, an adjusting seat is provided at the bottom end of the adjusting sleeve rod, and the support wheel body is provided at the bottom end of the adjusting seat. An auxiliary pressure-dividing mechanism extending to the outside is provided inside the adjusting seat. The auxiliary pressure-dividing mechanism includes adjusting plates provided on both sides of the adjusting seat. An auxiliary roller is provided on one side of each of the two adjusting plates, and a bolt is provided on one side of each adjusting plate.

[0006] Preferably, a connecting block extending into the interior of the adjusting seat is provided on one side of the adjusting plate, and a limiting plate is provided inside the adjusting seat.

[0007] Preferably, one end of the limiting plate is provided with a pull rod extending to the outside of the adjusting seat, and a spring is welded between the limiting plate and the adjusting seat.

[0008] Preferably, one end of the limiting plate is provided with a locking block extending into the interior of the connecting block, and the bottom end of the adjusting plate is provided with a first connecting plate.

[0009] Preferably, an anti-loosening mechanism is provided on one side of the adjusting sleeve rod, the anti-loosening mechanism includes a fixing frame provided on one side of the adjusting sleeve rod, and gears are provided on the surface of the handle.

[0010] Preferably, a rotating wheel is provided at the bottom of the fixed frame, and a threaded rod extending into the fixed frame is provided at one end of the rotating wheel, and a movable seat is provided on the surface of the threaded rod.

[0011] Preferably, one end of the movable seat is provided with a second connecting plate, one end of the second connecting plate is provided with a gear ring, and one end of the gear ring is meshed with a gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the bracket wheel with the auxiliary pressure-dividing structure can cause the locking block and the connecting block to separate by pulling the pull rod. Then, the adjustable plate can be rotated to be flush with the bracket wheel body, and the bolt can be rotated to lock it with the first connecting plate. This allows the auxiliary roller to quickly unfold on both sides of the bracket wheel body, so that the auxiliary roller can provide auxiliary pressure to the bracket wheel, thereby avoiding damage to a single bracket wheel body. After the handle is rotated, the rotatable wheel can drive the gear ring to mesh with the gear, thereby limiting the handle and preventing it from rotating after being hit when not in use. As a result, the bracket wheel has a better limiting effect when placed and used.

[0013] 1. The bracket wheel with auxiliary pressure-dividing structure can separate the locking block from the connecting block by pulling the pull rod. Then, the adjusting plate can be rotated to be flush with the bracket wheel body. Then, the bolt can be rotated to lock it with the first connecting plate, so that the auxiliary roller can quickly unfold on both sides of the bracket wheel body. This allows the auxiliary roller to provide auxiliary pressure to the bracket wheel, thereby avoiding damage to individual bracket wheel bodies and ensuring that the bracket wheel has a good auxiliary pressure-dividing effect during use.

[0014] 2. The bracket wheel with auxiliary pressure distribution structure can drive the moving seat and the second connecting plate to move after the handle is rotated. At the same time, the second connecting plate can drive the gear ring to move when it moves, so that the gear ring can mesh with the gear after it moves, thereby limiting the handle and preventing it from rotating after being hit when not in use. As a result, the bracket wheel can have a good limiting effect when placed and used. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] Please see Figures 1-4 It is understood that this utility model provides a technical solution: a support wheel with an auxiliary pressure-dividing structure, including an adjusting sleeve rod 1, a handle 2, an adjusting seat 3, and a support wheel body 4. The adjusting sleeve rod 1 has a handle 2 on one side, an adjusting seat 3 at its bottom end, and the support wheel body 4 at its bottom end. An auxiliary pressure-dividing mechanism 5 extending outwards is provided inside the adjusting seat 3. The auxiliary pressure-dividing mechanism 5 includes adjusting plates 501 on both sides of the adjusting seat 3, and auxiliary rollers are provided on one side of each of the two adjusting plates 501. The wheel 502, the adjusting plate 501 has a bolt 503 on one side, the adjusting plate 501 has a connecting block 504 extending into the adjusting seat 3 on one side, the adjusting seat 3 has a limit plate 505 inside, the limit plate 505 has a pull rod 506 extending into the outside of the adjusting seat 3 at one end, the limit plate 505 and the adjusting seat 3 are welded together with a spring 507, the limit plate 505 has a locking block 508 extending into the connecting block 504 at one end, and the adjusting plate 501 has a first connecting plate 509 at the bottom end.

[0023] See Figures 1-4It can be seen that by pulling the lever 506, the lever 506 can move the limiting plate 505, which in turn can compress the spring 507. The limiting plate 505 can also move the locking block 508, which can separate from the connecting block 504. Then, the adjusting plate 501 can be rotated to drive the auxiliary roller 502 to rotate. The adjusting plate 501 is rotated until it is flush with the bracket wheel body 4. Then, the bolt 503 is rotated to lock the bolt 503 with the first connecting plate 509. This allows the auxiliary roller 502 to quickly spread out on both sides of the bracket wheel body 4, thus enabling the auxiliary roller 502 to provide auxiliary pressure distribution on the bracket wheel and preventing damage to individual bracket wheel bodies 4. This ensures that the bracket wheel has a good auxiliary pressure distribution effect during use.

[0024] See Figure 1 , Figure 2 and Figure 5 It is known that an anti-loosening mechanism 6 is provided on one side of the adjusting sleeve rod 1. The anti-loosening mechanism 6 includes a fixed frame 601 provided on one side of the adjusting sleeve rod 1, a gear 602 provided on the surface of the handle 2, a rotating wheel 603 provided at the bottom of the fixed frame 601, a threaded rod 604 extending into the fixed frame 601 provided at one end of the rotating wheel 603, a movable seat 605 provided on the surface of the threaded rod 604, a second connecting plate 606 provided at one end of the movable seat 605, a gear ring 607 provided at one end of the second connecting plate 606, and one end of the gear ring 607 meshing with the gear 602.

[0025] See Figure 1 , Figure 2 and Figure 5 It can be seen that after the handle 2 is rotated, the rotating wheel 603 can be rotated, so that the rotating wheel 603 can drive the threaded rod 604 to rotate. When the threaded rod 604 rotates, it can drive the moving seat 605 to move. At the same time, when the moving seat 605 moves, it can drive the second connecting plate 606 to move. When the second connecting plate 606 moves, it can drive the gear ring 607 to move. After the gear ring 607 moves, it can mesh with the gear 602, thereby limiting the handle 2 and preventing it from rotating after being hit when not in use. As a result, the bracket wheel can have a good limiting effect when placed and used.

[0026] In summary, pulling the lever 506 causes the limiting plate 505 to compress the spring 507. When the limiting plate 505 moves, it can cause the locking block 508 to separate from the connecting block 504. Then, the adjusting plate 501 can be rotated to drive the auxiliary roller 502 to rotate. Rotate the adjusting plate 501 until it is flush with the bracket wheel body 4. Then rotate the bolt 503 to lock it with the first connecting plate 509. This allows the auxiliary roller 502 to quickly unfold on both sides of the bracket wheel body 4, thereby enabling the auxiliary roller 502 to assist in pressure distribution on the bracket wheel and avoid damage to a single bracket wheel body 4. This allows the bracket wheel to have a better auxiliary pressure distribution effect during use.

[0027] 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.
