Description

Technical Field

[0001] This utility model belongs to the field of automotive anti-skid chain technology, specifically relating to an automotive anti-skid chain structure that is convenient and adjustable for installation. Background Technology

[0002] Anti-skid chains are generally made of steel or rubber chains and have an anti-slip function. Based on their structure, anti-skid chains can be divided into two types: one is a pre-assembled, cover-like structure; the other consists of several individual anti-skid chains installed in a crisscross pattern. The former is simpler and cheaper, but less convenient to install than the former.

[0003] The applicant discovered that the existing anti-skid chain structure used on forklifts is made of steel wire. During installation, workers need to use horseshoe buckles and U-shaped shackles to bind the steel wire rope. Since the tires of forklifts are large, multiple steel wire ropes need to be bound. To ensure that the steel wire rope does not slip, workers also need to pull on the steel wire rope during installation to add locking buckles and increase the tension of the steel wire rope. However, the operation is relatively laborious and the installation time is long, which can easily affect the working cycle of the forklift and is inconvenient to use.

[0004] To address the aforementioned issues, this application proposes a convenient and adjustable automotive anti-skid chain structure. Utility Model Content

[0034] 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. Example

[0035] Please see Figures 1-7 This utility model provides the following technical solution: a convenient and adjustable car anti-skid chain structure, comprising:

[0036] The outer positioning plate 1 can be set on the outside of the tire. Multiple positioning screws 3 are evenly distributed on the outer positioning plate 1, and each positioning screw 3 is threaded with a No. 1 nut 4.

[0037] The inner positioning disc 7 can be set inside the tire. The inner positioning disc 7 is composed of a first half disc 701 and a second half disc 702 spliced ​​together. Multiple positioning screws 3 are also provided on the first half disc 701 and the second half disc 702, and a first nut 4 is threadedly connected to them.

[0038] Anti-slip steel wire rope 2, multiple anti-slip steel wire ropes 2 are wrapped in a fan shape on the surface of the tire, and are arranged in a parallel double strip design. One end is connected to the outer positioning plate 1, and the other end is connected to the inner positioning plate 7.

[0039] Adjustment component 5, multiple adjustment components 5 are correspondingly set on the anti-slip steel wire rope 2, the adjustment component 5 can move on the anti-slip steel wire rope 2, used to change the tension of the anti-slip steel wire rope 2;

[0040] Tensioning components 6, multiple tensioning components 6 are correspondingly arranged on the anti-slip steel wire rope 2 to support the anti-slip steel wire rope 2.

[0041] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, one end of the anti-slip steel wire rope 2 is sleeved on the positioning screw 3 on the outer positioning plate 1 and fixed by the first nut 4. The other end of the anti-slip steel wire rope 2 is sleeved on the positioning screw 3 on the first half plate 701 and the second half plate 702 and fixed by the first nut 4.

[0042] During installation, simply attach both ends of the anti-slip steel wire rope 2 to the positioning screw 3. Compared to the traditional method that requires workers to use clips for connection, this reduces manual labor, improves installation convenience, and speeds up the installation process, thereby increasing installation efficiency and facilitating faster application of the vehicle.

[0043] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, the outer positioning disk 1 has a plurality of lightweight holes 101 distributed along the circumferential direction, and a grip bar 102 is provided in the middle of the outer positioning disk 1.

[0044] This design reduces the weight of the device, making it easy to carry, handle, and install, thus enhancing its practicality.

[0045] Preferably, by Figure 2 , Figure 4 and Figure 7 As shown, in this embodiment, the first half-disc 701 and the second half-disc 702 are respectively provided with matching first mating port 703 and second mating port 705;

[0046] A fastening screw 704 is provided on the first half-disc 701, and a connecting hole 706 is provided on the second half-disc 702. The connecting hole 706 is sleeved on the fastening screw 704, and a third nut 707 is threadedly connected to the fastening screw 704.

[0047] After unscrewing nut 707, half disc 701 and half disc 702 can be separated, making it easy to attach them to the tire connecting rod during installation to install the anti-slip wire rope 2.

[0048] Preferably, by Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the adjustment component 5 includes a first plate 501 and a second plate 502 sleeved on the anti-slip steel wire rope 2;

[0049] A limiting groove 504 adapted to the anti-slip steel wire rope 2 is provided on the first plate 501. Bolt posts 503 are provided at the four corner plates of the first plate 501. A screw hole 505 is provided at the center of the first plate 501.

[0050] At each of the four corners of the second plate 502, there are socket holes 506 that are compatible with the bolt posts 503. A bearing 507 is provided in the middle of the second plate 502. A hand-tightening screw 508 that matches the screw hole 505 is provided on the second plate 502.

[0051] Nut 509 is screwed onto each of the multiple bolt posts 503;

[0052] Plate 501 and Plate 502 are connected and limited by bolt post 503 and nut 509 to form a clamping posture. They are set outside the two parallel anti-slip steel wire ropes 2. During the fixing period, when the hand screw 508 is turned counterclockwise, Plate 501 will move away from Plate 502, thereby releasing the clamping action, so that Plate 501 and Plate 502 can slide and adjust their positions on the anti-slip steel wire rope 2. When the hand screw 508 is turned clockwise, Plate 501 will move closer to Plate 502, thereby squeezing the anti-slip steel wire rope 2 to fix its position.

[0053] Among them, plate 501 and plate 502 can limit the two parallel anti-slip steel wire ropes 2 to avoid the risk of knotting or tangling during the movement of the car.

[0054] Preferably, by Figure 1 and Figure 3 As shown, in this embodiment, the tensioning assembly 6 includes a sleeve 602 sleeved on the anti-slip steel wire rope 2. Two sleeves 602 are sleeved on the parallel anti-slip steel wire rope 2. One sleeve 602 is provided with a positive thread screw 603, and the other sleeve 602 is provided with a negative thread screw 604.

[0055] Both the positive threaded screw 603 and the negative threaded screw 604 are threadedly connected to positive and negative threaded sleeves 601.

[0056] When in use, by rotating the positive and negative threaded sleeve 601 clockwise, due to the setting of the negative threaded screw 604 and the positive threaded screw 603, they will be pushed in opposite directions, thereby pushing the anti-slip steel wire rope 2 through the sleeve 602 connected to each other, causing the two parallel anti-slip steel wire ropes 2 to expand outward, thus ensuring that the anti-slip steel wire rope 2 can be stably fitted on the tire surface, reducing the risk of knotting or tangling, and improving the anti-slip performance;

[0057] After adjusting the positions of plate 501 and plate 502, if the anti-slip steel wire rope 2 is in a loose or tight state, the operator can manually turn the positive and negative thread sleeves 601 clockwise and counterclockwise to adjust the tightness. The adjustable range is large and the application range is wide. Compared with the traditional tightness adjustment which requires the operator to pull the steel wire rope, this device reduces manpower, is easy to install, and improves practicality.

[0058] Components not described in detail in this article are existing technologies.

[0059] The working principle and usage process of this utility model are as follows: When using it, firstly, the first half disc 701 and the second half disc 702 are separated and attached to the tire connecting rod. Then, a set of parallel anti-slip steel wire ropes 2 are taken and attached to the corresponding positioning screws 3 on the first half disc 701 or the second half disc 702, and fixed by limiting the position with the first nut 4.

[0060] Then, the outer positioning plate 1 is placed in the middle of the tire, so that the other end of the anti-slip steel wire rope 2 is sleeved on the positioning screw 3 and fixed by the first nut 4. After installing the remaining anti-slip steel wire ropes 2 in sequence, the hand screw 508 is turned to adjust the position of the first plate 501 away from the second plate 502 and fix it, so that the two anti-slip steel wire ropes 2 set side by side will not have a poor fit. Afterwards, the worker manually turns the positive and negative thread sleeves 601 clockwise and counterclockwise to adjust the tightness, forcing the anti-slip steel wire rope 2 to stick tightly to the tire surface. At the same time, both ends of the anti-slip steel wire rope 2 are tightened on the positioning screw 3 and limited by the first nut 4, thus realizing the anti-slip function. This device can be adjusted with little effort and has a wide range of applications. Compared with the traditional tightness adjustment that requires the worker to pull the steel wire rope, this device reduces manpower, is easy to install, and improves practicality.

[0061] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
