Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a novel tire-holding wheel sling. Background Art

[0002] When the vehicle needs to be transported as a whole and cannot be driven directly onto a large transport platform, it is necessary to use a car hoist to lift the entire vehicle onto the transport platform. Tire-holding wheel hoists are widely used as a type of hoist for vehicle transportation. Chinese invention patent application No. 202210724836.0 discloses a portable tire-holding wheel hoist and device. However, since its positioning claw arm and receiving claw arm are connected by a connector (bolt), and its positioning rod and the two receiving claw arms are also connected by bolts, when not in use, for the convenience of operation, the main components such as the positioning claw arm, the receiving claw arm and the connecting rod are generally disassembled into several single parts. Therefore, when storing and placing, it is easy to lose accessories and other abnormalities, which is not conducive to subsequent normal use. Utility Model Content

[0003] In view of the problem that the existing tire-holding wheel hanger is disassembled into single pieces when not in use, which is prone to losing accessories and is not conducive to subsequent normal use, the utility model provides a new tire-holding wheel hanger, which can be folded and stored when not in use, while the various accessories inside it still ensure connectivity, thereby ensuring subsequent long-term normal use.

[0004] The technical solution is as follows: a new type of tire-holding wheel hanger, which includes a positioning claw arm and two receiving claw arms, characterized in that the upper ends of the two receiving claw arms are connected to the positioning claw arm through a connecting structure, the lower ends of the two receiving claw arms are respectively rotatably connected to one end of a connecting rod, and the other ends of the two connecting rods extend into the side walls of the positioning block and are connected through the connecting structure.

[0005] It is further characterized in that: the positioning claw arm and the positioning block are respectively provided with cavities inside, the connecting structure includes a connecting bolt, and movable grooves communicating with the internal cavities of the positioning claw arm and the positioning block are respectively provided along the length direction of the positioning claw arm and the positioning block, the connecting bolt extends into the movable groove, the bottom of the cavity is provided with threaded holes arranged at intervals and cooperating with the connecting bolt, and a baffle is provided outside the shaft of the connecting bolt;

[0006] A spring is sleeved on the outside of the rod of the connecting bolt, one end of the spring abuts against the baffle, and the other end of the spring abuts against the top wall of the cavity;

[0007] The connecting rod is provided with a through hole for the connecting bolt to pass through;

[0008] An articulated seat is provided at the upper end connection of the two receiving claw arms, and the connecting bolt passes through the articulated seat and enters the cavity of the positioning grabbing arm.

[0009] After adopting the above structure, since the positioning grab arm and the receiving grab arm, and the receiving grab arm and the positioning block are connected by connecting structures respectively, the connection relationship can be guaranteed even when not in use. By adjusting the connection position with the connecting structure, it can be used normally and can also be folded and stored at the same time, which is convenient for storage and not easy to lose accessories, ensuring long-term normal use.

[0014] like Figures 1 to 4As shown, a novel tire-holding wheel hoist comprises a positioning claw arm 1 at the upper end and two receiving claw arms 2 at the lower end. The upper ends of the two receiving claw arms 2 are respectively provided with hinge seats, which are detachably connected to the positioning claw arm 1 through a connecting structure. The interior of the positioning claw arm 1 is provided with a cavity 9, and a movable groove 11 connected to the cavity 9 is provided along its length. The lower ends of the two receiving claw arms 1 are rotatably connected to one end of the connecting rod 6, respectively. The other ends of the two connecting rods 6 extend into the side wall of the positioning block 7 and are detachably connected to it through another connecting structure. The interior of the positioning block 7 is also provided with a cavity 9, and a movable groove 11 is provided along the length of the positioning block 7. Specifically, the connecting structure includes a connecting bolt 3, which passes through the hinge seat and extends from the movable groove 11 of the positioning claw arm 1, and another connecting bolt 3 extends from the movable groove 11 on the positioning block 7. A through hole for the connecting bolt 3 to pass through is provided on the connecting rod 6 that cooperates with the positioning block 7, and the corresponding connecting bolt 3 passes through the through hole on the connecting rod 6. The cavity 9 of the positioning grasping arm 1 and the cavity bottom of the positioning block 7 are respectively provided with spaced threaded holes 10 that cooperate with the connecting bolt 3. The connecting bolt 3 extends into the cavity 9 of the positioning claw arm 1 and the cavity of the positioning block 7 respectively and is threadedly connected with the threaded hole 10 at the bottom thereof, thereby completing the assembly of the positioning grasping arm 1 and the receiving grasping arm 2 and the adjustment of the width between the receiving grasping arm 2. Since the cavity 9 of the positioning claw arm 1 and the cavity of the positioning block 7 are respectively provided with multiple threaded holes 10, the threaded holes 10 at different positions can be connected to complete the assembly of different lengths and width adjustment requirements according to actual needs. A baffle plate 4 is also provided outside the shaft of the connecting bolt 3. The baffle plate 4 prevents the connecting bolt 3 from being separated from the cavity 9 of the positioning grab arm 1, thereby ensuring connectivity.

[0015] A connecting shaft 5 is also provided at the upper ends of the two receiving and grasping arms 1 , and the connecting shaft 5 is rotatably connected to the lugs on both sides of the two receiving and grasping arms 1 , and limiting sleeves are provided at both ends of the connecting shaft 5 .

[0016] A spring 8 is also mounted on the outside of the rod body of the connecting bolt 3, one end of the spring 8 is against the baffle 4, and the other end of the spring 8 is against the top wall of the cavity. Through the setting of the spring 8, when the connecting bolt 3 is disconnected from the threaded hole 10 at the bottom of the cavity, pressure can be provided to push the baffle 4 and the connecting bolt 3 connected thereto inward, thereby further preventing the connecting bolt 3 from detaching when the connection is disconnected from the positioning block 7 or the positioning grab arm 1, thereby preventing the loss of accessories.

[0017] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by anyone familiar with the technology within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
