Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, and in particular to a linear guide that can be quickly assembled. Background Technology

[0002] Linear guides are high-precision, low-friction linear transmission mechanisms widely used in various industrial automation equipment, such as machinery, electronics, instruments, and meters. Manufactured using precision machining techniques and high-quality materials, they ensure a high-precision fit between the guide rail and the slider, thereby achieving stable linear motion. Linear guides feature low friction, high rigidity, and high load capacity, maintaining high precision and stability even in high-speed, high-frequency motion, thus improving equipment operating efficiency and machining accuracy.

[0003] A search revealed a Chinese utility model patent with patent number CN222163238U, which discloses a linear guide rail that facilitates quick docking and assembly. Compared with the prior art, this utility model patent with Chinese patent number CN222163238U, through the setting of docking components, allows the two guide rail bodies to be installed simply by inserting the docking block into the docking groove. At the same time, the pointed structure on the left end of the docking block reduces the difficulty of inserting the docking block into the docking groove.

[0004] However, in actual use, the above-mentioned device uses the elastic potential energy of the spring to cooperate with the docking block and the docking slot for docking. However, during the actual operation of the guide rail, the elastic potential energy of the spring may change due to vibration, which may cause the docking block and the docking slot to lose contact, resulting in the derailment of the running equipment on the guide rail and damage to the equipment. Therefore, a linear guide rail with rapid docking and assembly is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of unstable fixation after docking in existing technologies, and to propose a linear guide rail for rapid docking and assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A linear guide rail for quick docking and assembly includes a guide rail body and a docking plate. The guide rail body and the docking plate are fixedly connected. The docking plate has symmetrically rotatably connected docking posts inside. The docking plate is provided with a connecting component for quick docking of the guide rail body and a limiting component for fixing the guide rail body.

[0008] The above technical solution further includes:

[0009] The connecting assembly includes a rotating shaft symmetrically rotatably connected to the outside of the guide rail body. One end of the rotating shaft extending into the inside of the guide rail body is fixedly connected to a drive bevel gear, and an internal hexagonal groove is provided at the end of the rotating shaft.

[0010] The docking post extends into the interior of the guide rail body and is fixedly connected to a driven bevel gear at one end near the driving bevel gear. The driving bevel gear and the driven bevel gear mesh with each other. Multiple slots are provided on the outer circumference of the docking post.

[0011] The docking plate has a first threaded hole symmetrically opened on the side away from the docking post. The first threaded hole is threadedly connected to the docking ring. The inner protrusion of the docking ring is adapted to the opening size of the groove. The first threaded hole and the docking post are coaxial.

[0012] The limiting component includes limiting grooves symmetrically opened on the outer side of the docking plate, and limiting mounting holes opened on the side of the docking plate away from the docking column. Limiting discs are symmetrically slidably arranged on the inner side of the limiting mounting holes, and the size of the limiting discs is adapted to the opening size of the limiting grooves.

[0013] The bottom of the docking plate is provided with a second threaded hole, and a sliding bolt is provided inside the second threaded hole. One end of the bolt, which extends to the inside of the limiting mounting hole, is rotatably connected to a trapezoidal block.

[0014] A fixing ring is symmetrically fixedly connected to the inner side of the limiting mounting hole, and a limiting post is slidably provided on the inner side of the fixing ring. The limiting post is fixedly connected to the limiting plate.

[0015] A spring is fixedly connected to both the fixing ring and the limiting plate. The spring is located outside the limiting post, and the two limiting posts are in contact with each other and the trapezoidal block.

Detailed Implementation

[0025] 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.

[0026] Example 1

[0027] like Figures 1-5 As shown, the linear guide rail for quick docking and assembly proposed in this utility model includes a guide rail body 1 and a docking plate 2. The guide rail body 1 and the docking plate 2 are fixedly connected. The docking plate 2 is symmetrically rotatably connected with docking posts 3. The docking plate 2 is provided with a connecting component for quick docking of the guide rail body 1 and a limiting component for fixing the guide rail body 1.

[0028] During use, the docking components are first used to quickly connect the two guide rail bodies 1 together, and then the set limiting components are used to fix them by pressure squeezing.

[0029] The mating plate 2 has a first threaded hole 8 symmetrically opened on the side away from the mating post 3. The first threaded hole 8 is threadedly connected to the mating ring 6. The inner protrusion of the mating ring 6 is adapted to the opening size of the groove 7. The first threaded hole 8 and the mating post 3 are coaxial.

[0030] First, insert the protrusions of the two adjacent mating plates 2 into the recessed part, then align the groove 7 of the mating post 3 with the protrusion of the mating ring 6 to achieve positioning, and then rotate the rotating shaft 4.

[0031] The connecting assembly includes a rotating shaft 4 symmetrically rotatably connected to the outside of the guide rail body 1. One end of the rotating shaft 4 extending into the inside of the guide rail body 1 is fixedly connected to a drive bevel gear 10. The end of the rotating shaft 4 is provided with an internal hexagonal groove.

[0032] During the docking process, a hex wrench needs to be inserted into the internal hexagonal groove of the rotating shaft 4, and then the rotating shaft 4 is rotated to drive the drive bevel gear 10 to rotate.

[0033] The docking post 3 extends into the interior of the guide rail body 1 and is fixedly connected to the driven bevel gear 11 at one end near the active bevel gear 10. The active bevel gear 10 and the driven bevel gear 11 mesh with each other. Multiple slots 7 are opened on the outer circumference of the docking post 3. The rotation belt of the active bevel gear 10 drives the driven bevel gear 11 to drive the docking post 3 to rotate. The docking post 3 drives the docking ring 6 to rotate, so that the docking ring 6 drives the adjacent docking plates 2 to move until the two adjacent guide rail bodies 1 are flush.

[0034] In this embodiment, during use, the docking post 3 is positioned by inserting it into the adjacent docking ring 6. Then, the rotating shaft 4 drives the active bevel gear 10 to rotate, which in turn drives the driven bevel gear 11 to rotate. The driven bevel gear 11 drives the docking post 3 to rotate, which in turn drives the docking ring 6 to rotate. The docking ring 6 is threadedly connected to the first threaded hole 8. The docking ring 6 drives the adjacent guide rail body 1 to move closer, until the two adjacent guide rail bodies 1 are flush.

[0035] Example 2

[0036] like Figures 1-5 As shown, based on Embodiment 1, the limiting component includes a limiting groove 5 symmetrically opened on the outer side of the docking plate 2. A limiting mounting hole 12 is opened on the side of the docking plate 2 away from the docking post 3. The limiting mounting hole 12 is used to install the limiting component. A limiting plate 13 is symmetrically slidably arranged on the inner side of the limiting mounting hole 12. The size of the limiting plate 13 is adapted to the opening size of the limiting groove 5. The two guide rail bodies 1 are fixed by the limiting plate 13 being inserted into the inner side of the limiting groove 5.

[0037] The bottom of the docking plate 2 is provided with a second threaded hole 14, which is threadedly connected to the bolt 9. The bolt 9 extends to the inner side of the limiting mounting hole 12 and is rotatably connected to a trapezoidal block 18.

[0038] After the above-mentioned docking is completed, the rotating bolt 9 rotates and rises inside the second threaded hole 14, and the rise of the bolt 9 drives the trapezoidal block 18 to rise.

[0039] A fixing ring 15 is symmetrically fixedly connected to the inner side of the limiting mounting hole 12. A limiting post 17 is slidably provided on the inner side of the fixing ring 15. The limiting post 17 is fixedly connected to the limiting plate 13. When the trapezoidal block 18 rises, it squeezes the two limiting posts 17 away from each other. The movement of the limiting post 17 drives the limiting plate 13 to be locked into the inner side of the limiting groove 5 for fixation.

[0040] A spring 16 is fixedly connected between the fixed ring 15 and the limiting plate 13. The spring 16 is located outside the limiting post 17. The two limiting posts 17 are in contact with each other with the trapezoidal block 18. The movement of the limiting post 17 causes the spring 16 to stretch. When the spring 16 releases the fixation between the two guide rail bodies 1, it plays the role of resetting the limiting post 17.

[0041] In this embodiment, after the docking is completed, the rotating bolt 9 rotates and rises inside the second threaded hole 14. The rise of the bolt 9 drives the trapezoidal block 18 to rise. The rise of the trapezoidal block 18 presses the two limiting posts 17 away from each other. The movement of the limiting posts 17 drives the limiting plate 13 to be locked into the inner side of the limiting groove 5 for fixation. The movement of the limiting posts 17 drives the spring 16 to stretch. When the spring 16 releases the fixation between the two guide rail bodies 1, it plays the role of resetting the limiting posts 17. Therefore, the vibration generated during use will not affect the connection between the two guide rail bodies 1.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
