Description
Technical Field
[0001] This utility model relates to the field of steering gear rack technology, specifically a modular splicing steering gear rack. Background Technology
[0002] Traditional steering racks typically use a one-piece structure, which requires replacement of the entire rack when it wears or breaks, resulting in high costs and low maintenance efficiency.
[0003] Although existing technologies include detachable rack designs, the fixing methods are complex, the stability is insufficient, and they are prone to loosening during long-term use.
[0004] Therefore, there is an urgent need for a modular, splicing steering rack that can both enable quick replacement of partially damaged parts and ensure the overall structural stability and reliability. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a modular splicing steering rack, which solves the problem of wear and breakage of the surface teeth of the steering rack. The splicing mechanism facilitates the replacement of the corresponding worn positions, and the corresponding broken splicing tooth blocks can be replaced by disassembling the positioning mechanism, thereby improving replacement efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular splicing steering rack, including a steering rod body, with a limiting placement groove at the upper end of the steering rod body. A splicing mechanism is detachably installed in the limiting placement groove, and the splicing mechanism includes a splicing tooth block. A positioning mechanism is provided on the outside of the steering rod body, and the positioning mechanism passes through the splicing tooth block and is fixedly installed with the steering rod body, thereby realizing the modular replacement of the splicing tooth block.
[0007] Furthermore: a protruding strip is fixed in the middle of the limiting placement groove, limiting strips are fixed on both sides of the lower end of the splicing tooth block, a groove is opened in the middle of the lower end of the splicing tooth block, the limiting strip matches the limiting placement groove, the protruding strip is inserted into the groove, an insert is fixed at the upper end of the protruding strip, a slot is opened in the groove of the splicing tooth block, and the insert is inserted into the slot for fixation.
[0008] Furthermore: the positioning mechanism includes a first insert rod, which passes through the front end of the steering rod and the insert block and is threadedly connected to the rear end of the steering rod. Second insert rods are symmetrically inserted on both sides of the lower end of the steering rod, and the second insert rods pass through the splicing tooth block and the steering rod and are threadedly fixed.
[0009] Furthermore: both the outer ends of the first and second inserts are provided with fixing grooves, and fixing plates are installed on the three fixing grooves. The fixing plates include inserts and retaining rings. The retaining rings respectively engage with the fixing groove ends of the first and second inserts. A lever is fixed to the lower end of the insert for disassembly.
[0010] Furthermore: a fixing button is sleeved on the outer side of the first and second insert rods, the fixing button being threadedly connected to the end of the steering rod body and pressing the upper end face of the insert plate to enhance fixation.
[0011] Furthermore, the splicing tooth blocks can be replaced independently. When damaged, only the positioning mechanism needs to be disassembled and the corresponding splicing tooth blocks replaced, without the need to replace the entire steering rod.
[0012] This invention provides a modular, splicable steering rack. Compared with the prior art, it has the following advantages:
[0013] This modular, interlocking steering rack features a modular interlocking design that allows for individual replacement of damaged parts, reducing maintenance costs.

[0021] 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.
[0022] Please see Figure 1-6 This utility model provides a technical solution: a modular splicing steering rack; specifically, it consists of a steering rod 1, which is one of the most important parts in automotive steering components. The steering rod 1 is a well-known technology in this field and will not be described in detail here. A limiting placement groove 2 is provided at the upper end of the steering rod 1, and a splicing mechanism is provided on the limiting placement groove 2. The splicing mechanism specifically includes a splicing tooth block 3, which is placed in the limiting placement groove 2. A positioning mechanism is provided at the outer end of the steering rod 1. The positioning mechanism passes through the splicing tooth block 3 and is inserted into the steering rod 1. The detachable splicing tooth block 3 can be replaced when damaged, thereby saving usage costs and improving replacement efficiency.
[0023] A protruding strip 5 is fixed in the middle of the limiting placement groove 2, and limiting strips 4 are fixed on both sides of the lower end of the splicing tooth block 3. A groove 6 is opened in the middle of the lower end of the splicing tooth block 3. The limiting strips 4 and the limiting placement groove 2 are matched and correspondingly set. The protruding strips 5 and the grooves 6 are matched and correspondingly set. During installation, the splicing tooth block 3 is placed vertically in the limiting placement groove 2, and the corresponding protruding strips 5 and grooves 6 are matched and inserted. Through the mutual support between the protruding strips 5 and the limiting strips 4, a stable installation effect is formed. At the same time, an insert 7 is fixed at the upper end of the protruding strip 5. The insert 7 is set vertically. A slot 8 is opened in the groove 6 at the lower end of the splicing tooth block 3. The insert 7 and the slot 8 are matched and inserted. One splicing tooth block 3 corresponds to two inserts 7, thereby forming a stable support. The positioning mechanism passes through the side of the steering rod body 1 to fix all the splicing tooth blocks 3 and inserts 7.
[0024] The positioning mechanism includes a first insert rod 9, which passes through the steering rod body 1 and the insert block 7, and is threaded to the other end of the steering rod body 1. This allows all the splicing tooth blocks 3 to be threaded together and fixed. A fixing groove 11 is provided at the outer end of the first insert rod 9. Symmetrical second insert rods 10 are provided on both sides of the lower end of the steering rod body 1. The second insert rods 10 pass through the splicing tooth blocks 3 and the steering rod body 1, and are threaded to the other end of the steering rod body 1. The second insert rods 10 can further stabilize the splicing tooth blocks 3 as a whole and improve the stability during use. Similarly, a fixing groove 11 is provided at the outer end of the second insert rod 10. A fixing plate is provided at the outer end of the first insert rod 9 and the second insert rod 10. The fixing plate stably limits the first insert rod 9 and the second insert rods 10 on both sides, thereby forming a stable support limit.
[0025] The fixing plate includes a insert 12, and three retaining rings 13 are fixed at the lower end of the insert 12. The retaining rings 13 correspond to the first insert 9 and the second insert 10 respectively, thus limiting the ends of the first insert 9 and the second insert 10 and preventing them from loosening. The plate is also easy and quick to install, as it can be pressed down from top to bottom. When disassembling, a lever 14 is fixed at the recessed part of the lower end of the insert 12. The insert 12 and the retaining rings 13 can be removed by pulling upward with the fingers through the lever 14.
[0026] A fixing button 15 is sleeved on the outside of the first insert 9 and the second insert 10. The fixing button 15 is threadedly connected to the end of the steering rod body 1, and the fixing button 15 can press the upper end face of the insert 12, thereby providing stable pressing and fixing.
