Description

Technical Field

[0001] The present application relates to the technical field of linear guide rails, and in particular to a foldable linear guide rail. Background Art

[0002] A linear guide is a guiding device used in precision machinery. It mainly consists of two parts: a guide rail and a slider. The guide rail is usually a long strip with high precision and excellent straightness. It is generally made of high-quality steel through precision machining. The surface is hardened, such as quenching, to increase wear resistance. The slider is the component that can slide on the guide rail. It contains many precision balls or rollers. These balls or rollers roll between the slider and the guide rail, forming rolling friction. Compared with traditional sliding friction, this rolling friction greatly reduces the friction force, allowing the slider to achieve high-precision, high-speed, and low-resistance linear motion on the guide rail. Linear guides are widely used in many fields such as industrial automation equipment, CNC machine tools, semiconductor manufacturing equipment, and robots. They can provide precise guidance and support for the moving parts of these devices, ensuring the accuracy and stability of equipment operation, thereby improving production efficiency and product quality.

[0003] Most of the existing guide rails are currently a complete overall structure, which has many limitations in actual application. First of all, this one-piece guide rail structure cannot be folded and adjusted, resulting in a relatively large volume and a long overall depth. In temporary use scenarios, it needs to be dismantled once use is completed. If it is then to be used again in another temporary location, the process of reuse is extremely inconvenient. On the one hand, inconvenience in carrying is a prominent problem. Whether it is transportation or storage, it requires a large space and consumes more manpower and material resources. On the other hand, this type of guide rail is not convenient for flexible length adjustment. In different usage scenarios, the demand for guide rail length may vary. However, the one-piece guide rail cannot meet this flexibility requirement. It can be seen that the existing one-piece guide rail has certain defects and deficiencies in the overall use process, and urgently needs to be improved and optimized to improve its applicability and convenience.

The bottom inner end of the connecting block 210 is fixedly connected with a positioning mechanism 250. The bottoms of the connecting block 210 are clamped to each other through the positioning mechanism 250. This device is composed of multiple groups of guide rail bodies 100, which are mutually clamped and installed through the clamping devices 200 at both ends. It is flexible and convenient. The connecting block 210 in the clamping device 200 can realize the folding of the guide rail body 100 through the design of the hinge 220 and the hinge slot 230, which is convenient for carrying and storage, and is particularly suitable for temporary use scenarios. The mounting mechanism 240 on the outside of the connecting block 210 ensures a secure and stable connection between the guide rail body 100, preventing it from easily separating during use and facilitating assembly and disassembly, enhancing ease of use. The positioning mechanism 250 on the inner end of the bottom further enhances the connection between the connecting blocks 210, ensuring good stability of the guide rail body 100 when deployed. The slider 300 slides on the outer surface of the guide rail body 100 to meet various linear motion requirements.

[0032] The top of the slider 300 is fixedly connected to the equipment fixing plate 400. The four outer corners of the equipment fixing plate 400 are provided with mounting holes 500. The mounting holes 500 are set as countersunk holes. The cross-sectional shape of the inner cavity of the slider 300 is set in a convex shape. The overall cross-sectional shape of the guide rail body 100 is set in an I-shaped shape. The equipment fixing plate 400 on the top of the slider 300 provides a stable platform for the installation of the equipment. The mounting holes 500 opened at the four outer corners of the equipment fixing plate 400 are countersunk holes. On the one hand, it makes the installation more beautiful and neat, and avoids the protrusion of the bolt head affecting the use and safety. On the other hand, the countersunk holes can make the bolt connection more stable and prevent the equipment from loosening due to vibration and other reasons during operation. The cross-sectional shape of the inner cavity of the slider 300 is convex, which cooperates with the overall I-shaped cross-sectional shape of the guide rail body 100. This cooperation makes the sliding of the slider 300 on the guide rail body 100 more stable and precise. The I-shaped guide rail body 100 has high strength and rigidity and can withstand a large load. At the same time, the cavity of the convex slider 300 can tightly wrap the guide rail body 100 to reduce shaking and deviation during the sliding process.

[0033] The positioning mechanism 250 includes a square groove 251 and a spring steel convex plate 252. The spring steel convex plate 252 is fixedly connected to the bottom of one connecting block 210. The square groove 251 is opened at the bottom of the other connecting block 210. The spring steel convex plate 252 is inserted into the interior of the square groove 251. The outer end of the spring steel convex plate 252 is provided with a positioning component 253. The positioning component 253 is clamped with the inner side of the square groove 251. The positioning component 253 includes a groove body 2531 and a limiting groove 2532. The groove body 253 A spring steel protrusion 252 is located at the bottom, near one end of the square slot 251. A telescopic spring 2533 is fixedly connected to each side of the slot 2531. The outer ends of the telescopic springs 2533 are fixedly connected to limit blocks 2534. Limit slots 2532 are located at both ends of the slot 2531, and the outer ends of the limit blocks 2534 are inserted into the limit slots 2532. The cooperation between the spring steel protrusion 252 and the square slot 251 ensures precise insertion and positioning at the bottom of the connecting block 210. The spring steel protrusion 252 has a certain degree of elasticity, providing a moderate tightening force when inserted into the square slot 251, ensuring a stable connection. Furthermore, the positioning assembly 253 further enhances the reliability of the connection. Once the spring steel protrusion 252 is inserted into the square slot 251, the telescopic spring 2533 within the slot 2531 pushes the limit blocks 2534 into the limit slot 2532, achieving a snap-fit connection. This design ensures a more secure connection and prevents loosening. To disassemble, simply press stop block 2534 to disengage stop slot 2532, making this operation quick and easy. The elasticity of telescopic spring 2533 can accommodate a certain degree of vibration and external impact, ensuring connection stability during use. Overall, this positioning mechanism 250 improves the connection accuracy and stability of the foldable linear guide while facilitating assembly and disassembly.

[0034] The mounting mechanism 240 includes a convex groove 241 and a reserved groove 242. The convex groove 241 is provided on the top outer side of the connecting block 210 and the top two ends of the guide rail. The reserved groove 242 is provided on the top two ends of the guide rail. The convex groove 241 is located on the outside of the reserved groove 242 on the guide rail. The interior of the convex groove 241 is interactively connected with a locking block 243. The top view of the locking block 243 is an I-shaped arrangement. The convex parts on both sides of the locking block 243 are arranged inside the convex groove 241. The interior of the reserved groove 242 is fixedly connected to the limiting component 245. The inner end of the limiting component 245 passes through the reserved groove 242 and is inserted into the interior of the convex groove 241. A card slot 244 is provided on the outside of the locking block 243. The end of the limiting component 245 is inserted into the interior of the card slot 244. The limiting component 245 includes The cam 2452 is fixedly connected to the top of the locking block 243 and the locking block 243 is fixedly connected to the locking block 243.

[0035] The locking block 243 is in an I-shape and the convex parts on both sides are located in the convex groove 241, which makes the connection more stable and can effectively prevent the relative displacement between the connecting block 210 and the guide rail body 100. The limiting component 245 in the reserved groove 242 further enhances the firmness of the connection. The limiting spring 2451 pushes the clamping block 2453 to insert into the clamping groove 244 on the outside of the locking block 243, achieving a reliable clamping connection and ensuring that it will not easily loosen during use. When disassembly is required, the clamping block 2453 can be disengaged from the clamping groove 244 by pulling the pull ring 2455 at the end of the connecting shaft 2454 on the inner side of the empty groove 2452. The operation is simple and convenient. This installation mechanism 240 makes the installation and disassembly between the guide rail body 100 and the connecting block 210 efficient, and improves the flexibility and practicality of the foldable linear guide in different usage scenarios.

[0036] The principle of use and advantages are as follows: By providing the mounting mechanism 240, during actual use, the outer side of the connecting block 210 can be first tightly aligned with the inner end of the guide rail body 100, with the convex grooves 241 now in contact. Next, the two ends of the locking block 243 are inserted into the convex grooves 241. Since the locking block 243 and the convex grooves 241 can move with each other, the guide rail body 100 and the connecting block 210 can be stably connected. After installation, the limiting spring 2451 pushes the clamping block 2453 outward, allowing the clamping block 2453 to be inserted into the clamping groove 244 on the locking block 243. At this point, the mutual restraint between the clamping block 2453 and the clamping groove 244 assists in the installation of the guide rail body 100, ensuring its stability. To disassemble, simply pull the pull ring 2455 inside the hole on the side to be disassembled. When the pull ring 2455 is pulled, it will drive the connecting shaft 2454 and thus move the block 2453 inward. After the block 2453 moves inward, it can be retracted into the reserved groove 242. At this time, the block 2453 leaves the groove 244, and the block 2453 and the groove 244 are separated from each other, and then the two ends of the locking block 243 in the convex groove 241 can be pulled out to realize the disassembly and separation of the guide rail body 100. Through the cooperation between the limit spring 2451, the block 2453 and the groove 244 of the locking block 243, the combined guide rail body 100 can be flexibly installed according to the specific combined installation requirements, which greatly improves the convenience of disassembly and separation of the integral guide rail body 100.

[0037] By providing a positioning mechanism 250, the device can be linked by adjusting the hinge 220 inside the hinge groove 230 when it is temporarily used. At this time, the two limit blocks 2534 can be adjusted to assist in the linked rotation, thereby adjusting the combined guide rail body 100 to be folded. When the guide rail body 100 needs to be unfolded, the two connecting blocks 210 can be unfolded. During this process, the spring steel protrusion 252 can be inserted into the inner side of the square groove 251. During this period, pressing the limit block 2534 inside the groove body 2531 will cause the telescopic spring 2533 to shrink and move inward. When the spring steel protrusion 252 is fully inserted into the square groove 251, the limit block 2534 is released, and the telescopic spring 2533 will reset, thereby prompting the telescopic spring 2533 to drive the limit block 2534 to insert into the limit groove 2532. The stopper 2534 and the stopper slot 2532 interlock, assisting in securing the spring steel protrusion 252 within the square slot 251. The mutual restraining action of the stopper 2534 and the stopper slot 2532 regulates the unfolded guide rail body 100, ensuring greater stability. To disassemble, simply repress the stopper 2534 within the slot 2531 to disengage it from the stopper slot 2532, allowing the guide rail body 100 to be quickly refolded. The slot 2531's interlocking design, comprised of the hinge slot 230, the square slot 251, the convex slot 241, the reserved slot 242, and the empty slot 2452, allows the slider 300 to flexibly and stably adjust its sliding motion after the guide rail body 100 is assembled. This makes the overall device easy to quickly disassemble, assemble, and fold for storage, further enhancing its ease of use.
