Description

Technical Field

[0001] The invention belongs to the technical field of guide rails, and in particular relates to a slotted guide rail for production. Background Art

[0002] Slotted guide rails are devices with grooves or ridges made of metal or other materials that can support, fix, guide moving devices or equipment and reduce their friction. The longitudinal grooves or ridges on the surface of the slotted guide rails are used to guide and fix machine parts, special equipment, instruments, etc. At present, slotted guide rails are gradually being used in various production and manufacturing fields.

[0003] Although there are many varieties of slotted guide rails currently available, there are still some problems. For example, most of the current slotted guide rails need to be used in combination with sliders. The slotted guide rails are used to limit the sliders to enable them to move in a certain direction. There is a certain degree of friction between the sliders and the guide rails, which causes a certain resistance to the sliders when they move. Long-term friction can easily lead to slippage and greater wear of the guide rails, thereby causing unnecessary economic losses. Summary of the Invention

The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0026] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] The embodiment of the present invention provides a slotted guide rail for production, such as Figure 1-5 As shown, it includes: a slotted guide rail body 1, a sliding mechanism 2 and a docking groove 3;

[0028] The slotted guide rail body 1 is provided with a mounting cavity inside, the sliding mechanism 2 is provided in the mounting cavity, and the docking groove 3 is provided at the top of the slotted guide rail body 1 and penetrates into the mounting cavity;

[0029] The sliding mechanism 2 includes a linkage plate 21, a driven plate 22, a supporting plate 23, a fixing frame 24, a rotating rod 25, a linkage unit and a limiting unit. The linkage plate 21 is slidably connected in the installation cavity and is symmetrically arranged. One end of the driven plate 22 is rotatably connected to the linkage plate 21, and the other end is rotatably connected to the supporting plate 23. The fixing frame 24 is set on the supporting plate 23, and the rotating rod 25 is rotatably connected to the fixing frame 24, and the rotating rod 25 is located in the docking groove 3.

[0030] It should be noted that since most of the existing slotted guide rails need to be used in combination with sliders, the slider is limited by the slotted guide rail to make it move in a certain direction, and there is a certain degree of friction between the slider and the guide rail, which leads to a certain resistance when the slider moves, and long-term friction can easily lead to slippage and greater wear of the guide rail, thereby causing unnecessary economic losses. In order to solve this problem, a sliding mechanism 2 is provided in this solution, and the linkage unit in the sliding mechanism 2 drives the linkage plate 21 to be linked, and then the linkage plate 21 drives the driven plate 22 to be linked, and the supporting plate 23 is lifted from the inside of the slotted guide rail body 1, so that the rotating rod 25 is moved out of the docking groove 3 and abuts against the slider connected to the slotted guide rail body 1. The friction between the external slider and the slotted guide rail body 1 is reduced by the rotation of the rotating rod 25, which reduces the resistance while effectively reducing the wear, which is economical and practical.

[0031] Specifically, in this embodiment, this scheme mainly includes a slotted guide rail body 1, a sliding mechanism 2 and a docking groove 3. When in use, the external slider is first connected to the slotted guide rail body 1, and then the active rod 29 is rotated to drive the worm 210 to rotate, and the worm wheel 28 is meshed and linked through the worm 210, and then the transmission rod 26 is rotated, and the transmission rod 26 causes the linkage plate 21 to be threaded and linked through the thread 27, and slips, and the driven plate 22 is driven to be linked through the linkage plate 21, and then the supporting plate 23 is driven to drive the rotating rod 25 set thereon to move out of the docking groove 3 and abut against the bottom of the slider. The friction between the external slider and the slotted guide rail body 1 is reduced by the rotation of the rotating rod 25, which is simple and efficient.

The transmission rod 26 is rotatably connected to the inside of the mounting cavity of the slotted guide rail body 1. The thread 27 is arranged on the outer wall of the transmission rod 26, and a screw hole is provided through the linkage plate 21. The transmission rod 26 passes through the screw hole and cooperates with the screw hole thread through the thread 27.

[0040] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the limiting unit includes a limiting plate 211 and a limiting rod 212. The limiting plate 211 is coaxially fixed on the active rod 29, and a slot is provided at the edge of the limiting plate 211. The limiting rod 212 is slidably connected to the inner wall of the mounting cavity of the slotted guide rail body 1, and one end of the limiting rod 212 abuts against the slot of the limiting plate 211.

[0041] In this embodiment, the limiting plate 211 is limited by the limiting rod 212 to prevent the active rod 29 from rotating.

[0045] In this embodiment, the linkage plate 21 is limited by the guide block 216 and the guide groove 217 so that the linkage plate 21 can slide in a certain direction.

[0046] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the guide block 216 and the guide groove 217 are both dovetail-shaped structures.

[0047] In this embodiment, the guide block 216 is limited by a dovetail structure to prevent it from slipping.
