Description

Technical Field

[0001] This utility model relates to the field of studded tire technology, specifically a studded tire. Background Technology

[0002] Utility model patent CN222473825U discloses a studded tire, including a tire tread with lateral grooves one, two lateral grooves, one longitudinal groove, two longitudinal grooves, and three longitudinal grooves. Lateral groove one communicates with longitudinal groove two, and lateral groove two communicates with longitudinal groove three. This device uses multiple non-continuous longitudinal grooves and multiple lateral grooves arranged in a herringbone shape on the tire tread. The longitudinal and lateral grooves divide the tread into multiple tread blocks. Each tread block has multiple narrow sipes distributed on its circumferential surface, and each tread block has anti-skid stud holes distributed on its circumferential surface. The number of anti-skid stud holes is no less than 100 per meter of rolling circumference, which improves the tire's grip on icy and snowy surfaces while effectively reducing tire wear. However, this device has some shortcomings in use: the tire generates significant noise during operation, and the studs are inconvenient to install and remove. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a studded tire that solves the problems of excessive tire noise during use and the inconvenience of installing and removing the studs from the tire.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a studded tire, comprising a tire body, a first groove provided on the tire body, a second groove provided on the tire body, a tread block fixedly connected to the surface of the tire body, an insert slidably connected inside the tread block, the insert slidably connected to the tire body, a connecting block fixedly connected to the surface of the insert, the connecting block contacting the tread block, and a fixing mechanism provided on the insert.

[0005] Preferably, the fixing mechanism includes a wedge block, with the wedge block slidably connected inside the insert, a toothed plate fixedly connected to the surface of the wedge block, the toothed plate slidably connected to the insert, a top block slidably connected to the surface of the wedge block, a guide rod fixedly connected inside the insert, the guide rod slidably connected to the wedge block, and a spring provided on the outer side of the guide rod. By rotating the screw and the top block to perform threaded movement, the top block presses against the wedge block, which in turn causes the toothed plate to move its teeth, thus pressing the teeth into the tire body, making it easy to assemble and disassemble the insert within the tire body.

[0006] Preferably, the top block has a screw threadedly connected to its interior, and the screw and the connecting block are connected by a bearing. The screw drives the top block to move.

[0007] Preferably, a sliding pin is fixedly connected to the surface of the top block, and the sliding pin is slidably connected to the insert. The movement of the top block is controlled by setting the sliding pin.

[0008] Preferably, the surface of the toothed plate is fixedly connected with teeth, which are slidably connected to the tire body. The teeth limit the movement of the insert.

[0009] Preferably, one end of the spring contacts the insert, and the other end of the spring is fixedly connected to the inclined block. By providing the spring, the inclined block can be easily reset.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model features V-shaped single-guide tread blocks on the tire body. The overall tread blocks have no circumferential grooves. The "stepped" groove design of the tread blocks is interspersed within the left and right tread blocks. At the same time, computer optimization theory is used to optimize the performance of the tread block pitch arrangement, reducing the impact noise of the tread blocks, the pumping noise of the tread grooves, and the air column resonance noise of the transverse grooves, thus achieving a noise reduction effect. The multi-pitch and staggered arrangement of the inserts improves the tire's grip on icy and snowy surfaces while effectively reducing tire wear on the ground and reducing the noise of studded tires.

[0012] 2. This utility model uses the rotating screw and top block to make a threaded movement, which causes the top block to press the inclined block, which in turn causes the tooth plate to move the teeth, which in turn causes the teeth to be pressed into the tire body, making it easy to assemble and disassemble the insert in the tire body.

[0017] 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.

[0018] Please see Figures 1-2 A studded tire includes a tire body 1, a first groove 2 and a second groove 3 on the tire body 1, a tread block 4 fixedly connected to the surface of the tire body 1, an insert 5 slidably connected inside the tread block 4, the insert 5 and the tire body 1 being slidably connected, a connecting block 6 fixedly connected to the surface of the insert 5, the connecting block 6 contacting the tread block 4, and a fixing mechanism 7 on the insert 5.

[0019] Please see Figures 2-3 The fixing mechanism 7 includes a wedge block 71, which is slidably connected to the inside of the insert 5. A toothed plate 72 is fixedly connected to the surface of the wedge block 71, and the toothed plate 72 is slidably connected to the insert 5. Teeth 73 are fixedly connected to the surface of the toothed plate 72, and the teeth 73 are slidably connected to the tire body 1. The teeth 73 limit the position of the insert 5. A top block 74 is slidably connected to the surface of the wedge block 71, and a sliding pin 75 is fixedly connected to the surface of the top block 74. The sliding pin 75 is slidably connected to the insert 5, and the movement of the top block 74 is controlled by the sliding pin 75. A screw 76 is threadedly connected to the inside of the top block 74, and the screw 76 and the connecting block 6 are connected by a bearing. The connection is achieved by setting a screw 76 to drive the top block 74 to move. The inside of the insert 5 is fixedly connected to a guide rod 77, which is slidably connected to the inclined block 71. A spring 78 is set on the outside of the guide rod 77. One end of the spring 78 contacts the insert 5, and the other end of the spring 78 is fixedly connected to the inclined block 71. By setting the spring 78, the inclined block 71 can be easily reset. By rotating the screw 76 and the top block 74 to make threaded movement, the top block 74 presses the inclined block 71, which in turn causes the toothed plate 72 to drive the teeth 73 to move, which in turn causes the teeth 73 to be pressed into the tire body 1, thus making it easy to assemble and disassemble the insert 5 in the tire body 1.

[0020] The specific implementation process of this utility model is as follows: In use, the insert 5 is inserted into the tire body 1 after passing through the patterned block 4. Then, the screw 76 is rotated, and the screw 76 rotates and the top block 74 makes a threaded movement, which causes the top block 74 to press against the inclined block 71. This causes the inclined block 71 to drive the toothed plate 72 to move, which in turn causes the toothed plate 72 to drive the toothed teeth 73 to move. The moving toothed teeth 73 contact and press against the tire body 1. By rotating the screw 76 and the top block 74 to make a threaded movement, the top block 74 presses against the inclined block 71, which in turn causes the toothed plate 72 to drive the toothed teeth 73 to move, which in turn causes the toothed teeth 73 to be pressed into the tire body 1, thus allowing the insert 5 to be inserted into the tire body 1. For disassembly and assembly, V-shaped single-guide tread blocks 4 are set on the tire body 1. The overall tread block 4 has no circumferential groove design. The "stepped" groove design of the tread block 4 is used, which is interspersed within the range of the left and right tread blocks 4. At the same time, computer optimization theory is used to optimize the performance of the pitch arrangement of the tread block 4, reduce the impact noise of the tread block 4, the pumping noise of the tread groove, and the air column resonance noise of the transverse groove, thereby achieving the effect of noise reduction. The multi-pitch and staggered arrangement of the inserts 5 design improves the tire's grip on icy and snowy surfaces while effectively reducing tire wear on the ground and reducing the noise of studded tires.
