Description

Technical Field

[0001] The utility model relates to the technical field of lifting tools, in particular to a tire-holding type wheel lifting tool. Background Technique

[0002] When a vehicle needs to be transported as a whole and cannot be directly driven onto a large transportation platform, using an automobile lifting tool to lift the whole vehicle onto the platform can improve the mobility performance of the overall rapid, safe transportation, loading and unloading of the equipment. The tire-holding type wheel lifting tool, as a common automobile lifting tool, is widely used in the field of vehicle hoisting. The existing tire-holding type wheel lifting tool, such as a tire-holding type wheel lifting tool disclosed in the Chinese utility model patent application No. CN02248799.9, since the metal pipes 1 and 2 of its bracket 3 are connected by an adjusting rod 6, and the adjusting rod 6 is specifically composed of two sections of screw rods and a sleeve threadedly connected thereto. When adjusting the width between the metal pipes 1 and 2 (i.e., the two clamping arms), it is necessary to rotate the sleeve for adjustment. By using this method, after using for a period of time, the threads will be worn and slippery, etc., resulting in affecting the safety of use. And if the traditional method of mutual cooperation of fixed holes and pins is adopted, there is a risk of pin detachment, and there are still safety problems. Content of the Utility Model

[0003] Aiming at the problem that when adjusting the width of the two clamping arms of the existing tire-holding type wheel lifting tool, after using for a period of time, the connection is prone to be unstable, affecting the safety of use, the utility model provides a tire-holding type wheel lifting tool, the width adjustment of its clamping arms is reliable, has a long service life, and ensures the safety of use.

[0004] Its technical solution is as follows: A tire-holding type wheel lifting tool, which includes two "L"-shaped lifting arms, the upper ends of the two lifting arms are rotationally connected through a connecting shaft, and a first connecting rod is provided near the upper ends of the two lifting arms. It is characterized in that: an adjusting mechanism is further provided near the lower ends of the two lifting arms, the adjusting mechanism includes a second connecting rod with one end respectively connected to the lower ends of the two lifting arms, and the other ends of the two second connecting rods extend into the reinforcing rod and are locked and connected through a locking member.

[0005] It is further characterized in that: the end of the second connecting rod connected to the lifting arm is a "U"-shaped connecting rod, and the connecting rod is fixedly connected to the lug on the lifting arm through a combination of a bolt and a nut;

[0006] The other end of the second connecting rod is a straight rod, two or more connecting holes are provided on the straight rod, an installation hole is provided on the reinforcing rod, the locking member is a combination of a locking bolt and a locking nut, the locking bolt passes through the installation hole on the reinforcing rod and the connecting hole on the straight rod, and the lower end is locked by the locking nut.

[0007] After adopting the above structure, since an adjusting mechanism is provided near the lower ends of the two lifting arms, the adjusting mechanism includes a second connecting rod and a reinforcing rod. The second connecting rod extends into the reinforcing rod and is locked and connected through a locking member. In this way, the reinforcing rod and the second connecting rod cooperate with each other to not only adjust the distance, but also enhance the reliability of the connection. After being locked by the locking member, the stability after connection can be ensured, thereby ensuring the safety of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 is a schematic diagram of the overall structure of the present invention;

[0009] Figure 2 is a schematic diagram of a partial structure of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0010] As Figure 1 , 2 shown, a tire-holding wheel hoist includes two "L"-shaped lifting arms 1. The upper ends of the two lifting arms 1 are rotatably connected through a connecting shaft. A first connecting rod 2 is provided near the upper ends of the two lifting arms 1. Both ends of the first connecting rod 2 pass through the lifting lugs vertically arranged at the upper ends of the lifting arms 1, and the ends are limited by limit caps. An adjusting mechanism is also provided near the lower ends of the two lifting arms 1. The width of the two lifting arms 1 is adjusted through the adjusting mechanism. Specifically, the adjusting mechanism includes a second connecting rod 3 whose one end is respectively connected to the laterally arranged lifting lugs at the lower ends of the two lifting arms 1. The other end of the second connecting rod 3 extends into a reinforcing rod 4 and is locked and connected through a locking member 5. One end of the second connecting rod 3 connected to the lifting arm 1 is a "U"-shaped connecting rod 31. The connecting rod 31 is fixedly connected to the laterally arranged convex lug on the lifting arm 1 through a combination of a bolt and a nut. The other end of the second connecting rod 3 is a straight rod 32, and two or more connecting holes (not shown in the figure) are provided on the straight rod 32. The reinforcing rod 4 is a rectangular rod with a rectangular cross-section. A hollowed-out portion is provided on the rectangular rod. Mounting holes 41 are provided through the upper end face and the lower end face of the reinforcing rod 4. The locking member 5 can be selected as a combination of a locking bolt and a locking nut. The locking bolt passes through the mounting hole on the reinforcing rod 4 and the connecting hole on the straight rod 32, and the lower end is locked and connected through a locking nut. Since two or more connecting holes are provided on the connecting rod 3, after connecting to the reinforcing rod 4 through different connecting holes, the distance between the two lifting arms 1 can be adjusted to different widths, which is convenient for folding and storage and improves portability. At the same time, one end of the second connecting rod 3 is set as a "U"-shaped rod for strengthening connection with the lifting arm 1. The other end of the second connecting rod 3 extends into the reinforcing rod 4 and is connected to it through the locking member 5, ensuring the reliability and strength of the connection. At the same time, the locking member 5 can be replaced regularly to prevent abnormal situations such as thread slipping and excessive wear, ensuring the reliability of the connection and the safety of use.

[0011] 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.
