Description

Technical Field

[0001] This utility model relates to the field of steel-plastic composite strap technology, and in particular to a car tire fastening strap. Background Technology

[0002] When transporting cars by rail over long distances, the cars are usually driven into the car body of a special car transport vehicle and stopped. The four tires of the car are then wrapped around and fixed to the floor of the special car transport vehicle using the fastening straps of the wheel clamps, thus securing the car and the special car transport vehicle as one unit.

[0003] Currently, the fastening bands of wheel clamps are made of polyester braided tape. The main problem is that the braided tape, made of a polymer material, has a high elongation rate. After prolonged tightening and stress, it is prone to permanent elongation, leading to loosening. In severe cases, the fastening band may detach, causing the car to lose its fixation and resulting in damage. In addition, the braided tape is not resistant to wear and scratches and is easily cut or severed, resulting in a high damage rate in practical applications.

[0004] The above problems are particularly prominent because cars are transported by rail in a state of prolonged unattended operation.

[0005] Therefore, there is an urgent need for a tire fastening belt for automobiles. Utility Model Content

[0006] This utility model provides a car tire fastening belt that solves the problems of high damage rate, permanent elongation and loosening of fastening belts after long-term use, and in severe cases, fastening belt falling off, causing the car to lose its fixation.

[0007] This utility model provides a car tire fastening belt, characterized in that it includes a polymer outer rubber belt and a steel wire rope inner mesh curtain, wherein the polymer outer rubber belt is molded or injection molded over the outside of the steel wire rope inner mesh curtain.

[0008] Preferably, the inner mesh curtain of the car tire fastening belt comprises multiple strands of steel wire rope and high-strength polyester yarn, wherein the multiple strands of steel wire rope are warp and the high-strength polyester yarn is weft, and a braided section is formed by weaving the warp and weft, and there are gaps between adjacent braided sections. The outer polymer adhesive tape is molded or injection molded to cover the outside of the braided section, and the outer polymer adhesive tape fills the gaps between adjacent braided sections by molding or injection molding.

[0009] Preferably, in the aforementioned automotive tire fastening band, the gap between adjacent braided sections is 1.5-2.5 times the width of the braided section.

[0010] Preferably, the polymer outer adhesive tape of the aforementioned automobile tire fastening tape includes a head section, a middle section, and a tail section, which are connected in sequence, and the middle section is provided with a plurality of protruding rectangular blocks.

[0011] Preferably, one end of the tire fastening band is connected to a hook loop via a rectangular buckle.

[0012] Preferably, the material of the polymer outer adhesive tape in the aforementioned automotive tire fastening tape is polyurethane.

[0013] The beneficial effects are:

[0014] 1. This utility model adopts an integrated composite belt structure formed by wrapping a steel wire rope inner mesh curtain with a polymer outer gel belt, making the automotive tire fastening belt of this utility model an integrated component. The outer surface of this utility model is wear-resistant and scratch-resistant, with high friction coefficient and flexibility, and has high overall strength and low elongation, making it particularly suitable for the performance requirements of tire fastening belts.

[0015] 2. The outer rubber belt of this utility model has multiple protruding rectangular blocks. The rectangular blocks are arranged in a row with intervals and continuity. Without affecting the overall flexibility, the rectangular blocks can be embedded in the tire groove, so that the tire fastening belt of this utility model is laterally positioned on the tire surface to prevent the tire fastening belt from loosening and shifting laterally due to vibration.

[0016] 3. This utility model's inner wire rope mesh curtain uses a mesh strip structure woven from multiple strands of steel wire rope and high-strength polyester yarn. This ensures the steel wire rope can withstand axial tension, while utilizing the weaving characteristics of the high-strength polyester yarn and the steel wire rope, along with the adhesive strength of the outer rubber band, prevents axial movement of the steel wire rope. Furthermore, the high-strength polyester yarn prevents lateral deformation and tearing of the tire fastening belt. Its manufacturing process is simple and inexpensive. The inner wire rope mesh curtain has a large space between the steel wire rope and polyester yarn for filling with rubber, resulting in high bonding strength on both sides of the rubber and a firm overall bond between the rubber and the steel wire rope.

[0017] 4. Due to its steel-plastic composite structure, this utility model, while maintaining the same function, has higher strength, lower elongation, and higher friction with the tire contact surface than the original woven polyester belt, thus preventing loosening. Furthermore, it is wear-resistant, scratch-resistant, and shear-resistant, greatly extending its service life. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, it should be noted that the terms "external" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the system or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] This utility model provides an automotive tire fastening belt, comprising a polymer outer rubber belt and a steel wire rope inner mesh curtain. The polymer outer rubber belt is molded or injection molded over the steel wire rope inner mesh curtain. Due to its steel-plastic composite structure, this utility model, while maintaining the same function, offers higher strength, lower elongation, and higher friction with the tire contact surface compared to traditional woven polyester belts, thus preventing loosening. Furthermore, it is wear-resistant, scratch-resistant, and shear-resistant, significantly extending its service life.

[0032] The following section uses a type of automotive tire fastening belt as an example to illustrate the entire technical process in detail.

[0033] Example 1

[0034] like Figures 1 to 4 As shown, this utility model provides a car tire fastening belt, including a polymer outer rubber belt 1 and a steel wire rope inner mesh curtain 2. The polymer outer rubber belt 1 is molded or injection molded onto the outside of the steel wire rope inner mesh curtain 2.

[0035] The material of the polymer outer colloid 1 is polyurethane, and the polymer outer colloid 1 is a continuous strip with a rectangular cross section.

[0036] like Figure 1 As shown, the polymer outer colloid belt 1 includes a head section 12, a middle section 12 and a tail section 13, which are connected in sequence. The middle section 12 is provided with multiple protruding rectangular blocks 11.

[0037] When the rectangular blocks 11 are used to fasten the car tires with the tire fastening belt, the rectangular blocks 11 are embedded in the grooves on the surface of the car tire to prevent it from loosening and slipping off. The spaced rectangular blocks 11 can ensure that the flexural section modulus of the polymer outer rubber belt 1 is consistent when it is bent, so that the car tire fastening belt has consistent flexibility as a whole.

[0038] The outer rubber belt 1 replaces the woven polyester belt for use in wheel fasteners to secure automobile tires.

[0039] like Figure 2 and Figure 4 As shown, the inner wire rope mesh curtain 2 includes multiple strands of steel wire rope 20 and high-strength polyester yarn 21. The multiple strands of steel wire rope 20 are the warp, and the high-strength polyester yarn 21 is the weft. The warp and weft are woven together to form a continuous strip-shaped mesh curtain, which can be cut to the required length for use with tire fastening belts. The inner wire rope mesh curtain 2 includes a braided section 23 and a gap 22 between the braided sections. After the polyurethane material of the outer polymer outer adhesive belt 1 fills the gap 22, the polyurethane material of the outer adhesive belt 1 can be fully connected layer by layer, preventing delamination due to the presence of the inner wire rope mesh curtain 2.

[0040] The distance between adjacent knitted sections 22 is 1.5-2.5 times the width of the knitted section 23. Preferably, the distance between adjacent knitted sections 22 is twice the width of the knitted section 23.

[0041] Preferably, the wire rope 20 is a 1×19 wire rope with a diameter of φ1.2mm to φ2mm. Preferably, the width of the braided part 23 is 3mm and the distance between the gaps 22 between adjacent braided parts is 6mm.

[0042] The multi-strand steel wire rope 20 is used to transmit tension and has the characteristics of low elongation and no permanent deformation. The high-strength polyester yarn 21 is used to fix the position of the multi-strand steel wire rope 20, increase the lateral tension between the steel wire ropes 20, and can increase the connection between the steel wire ropes 20 to make the force uniform and prevent core pulling.

[0043] like Figure 5 and Figure 6 The assembly process of this utility model is shown in the following steps:

[0044] Step S1: Before applying the tire fastening belt in Example 1, assemble the components of the wheel fastener.

[0045] Step S1 includes the following steps:

[0046] First, pass the end of the head section 12 of the car tire fastening belt through the rectangular buckle 202, then pass it around the middle of the hook 201 and fold it in half. After folding, pass the end of the head section 12 back through the rectangular buckle 202.

[0047] The second step is to adjust the position and place the rectangular buckle 202 into the press mold to press it, so that the rectangular buckle 202 presses the head section 12 and the folded end, so that the head section 12 and the hook 201 are connected in a ring.

[0048] Third, the tail end of the tail section 13 is fixed and wrapped around the central shaft of the fastener 203. Rotating the central shaft can coil the car tire fastening belt in Embodiment 1 into multiple layers on the central shaft. Since the central shaft is equipped with a ratchet anti-reverse mechanism, rotating the central shaft can tighten the car tire fastening belt and prevent it from being reversed and loosened.

[0049] Step S2: When it is necessary to fix the car tire in the special vehicle transport vehicle of railway transport, first insert the hook 201 into the long hole of the truck floor 200 on the right side of the tire 100 and fix it. Then, wrap the middle section 10 of the car tire fastening belt around the top of the tire 100 and install a row of positioning rectangular blocks 11 into the groove of the tire tread of the tire 100. Then fix the fastener 203 in the long hole of the truck floor 200 on the left side of the tire 100 and rotate the central shaft of the fastener 203 to tighten the tire fastening belt 1.

[0050] Because this invention features high strength, low elongation, and a high coefficient of friction, it can maintain a tight fit for extended periods without loosening. Furthermore, it is wear-resistant, scratch-resistant, shear-resistant, and tear-resistant, thus significantly extending its service life and providing excellent economic benefits.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
