Description

Technical Field

[0001] This utility model belongs to the field of cross rail technology, and in particular relates to a cross rail connection and fixing device. Background Technology

[0002] Crossed guide rails are a type of high-rigidity, high-precision, and compact finite linear motion system, also known as crossed ball guide rails.

[0003] Because the surfaces of the various parts of the cross guide rail are relatively smooth, they are prone to movement when installed on the slide rail. This requires constant pressure on the position of each part of the cross guide rail to prevent misalignment during connection, which could lead to improper assembly. Consequently, bolts can only be placed and tightened with one free hand, which is inconvenient.

[0004] Therefore, how to provide a cross rail connection and fixing device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a cross rail connection and fixing device to solve the problems mentioned in the background art.

[0006] This utility model is implemented as follows: a cross rail connection and fixing device, comprising; Support base; Support plates, the array of support plates being disposed at the bottom of the support base; A rotating ring plate, which is movably placed on top of a support plate and has a groove in the middle; The first protrusion is fixedly installed in the middle of the support plate and slidably disposed inside the slide groove; The support rods are arranged in a circumferential array on the inner side of the slide groove, and a positioning frame is fixedly installed on the inner side. The slide rail is movably disposed inside the positioning frame, and a cross guide rail body is slidably disposed inside it; A limiting plate is movably hinged to the outside of the lower support rod, and a second through groove is provided on its surface; A limiting structure is provided on the surface of the upper and lower end support rods and is movably inserted into the second through groove for limiting the outer side of the positioning frame.

[0007] Preferably, a positioning structure is movably provided on the top of the rear side of the left end support base. The positioning structure includes a pressure plate and a slot. The pressure plate is movably hinged to the top of the rear side of the support plate, and a limiting toothed ring is fixedly installed at the bottom and movably inserted into the slide groove. The slot is opened on the front side of the left end support plate, and a positioning unit is movably provided on the front side of the pressure plate and movably inserted into the slot.

[0008] Preferably, the limiting structure includes a first through groove, a guide rod, a limiting rod, a spring, and a limiting block. The first through groove is arrayed on the surface of the upper and lower end support rods. The guide rod is fixedly installed in the middle of the first through groove. The limiting rod is symmetrically arranged at the upper and lower ends of the first through groove and is slidably disposed on the surface of the guide rod. The limiting block is fixedly installed at the outer end of the limiting rod and is movably inserted into the first through groove. The spring is movably sleeved on the surface of the guide rod and movably abuts against the inner side of the limiting rod.

[0009] Preferably, the positioning unit includes a movable rod and an insert block. The movable rod is movably hinged to the bottom of the front side of the pressure plate, and the insert block is fixedly installed on the inner side of the movable rod and movably inserted into the slot.

[0010] Preferably, the cross-sectional size of the limiting toothed ring is equal to the cross-sectional size of the slide groove, and the surface of the slide groove is provided with toothed grooves, which are correspondingly arranged with respect to the limiting toothed ring.

[0011] Preferably, the limiting plate is a cross-shaped limiting plate, and the position of the first through groove on the surface of the limiting plate is set to correspond to the position of the upper and lower limiting structures.

[0013] Compared with the prior art, the beneficial effects of this utility model are: when in use, by symmetrically setting limiting structures at the upper and lower ends of the support rod on the surface of the rotating ring plate, the position of the limiting plate at either end can be fixed, thereby abutting and limiting the outer side of the positioning frame in the middle of the rotating ring plate. Thus, when placing the cross guide rail body, it can be quickly inserted, and the positioning frames on both sides can be limited, thereby facilitating the flipping of the slide rail.

[0014] Meanwhile, by setting a positioning structure on the left end support plate, the flexibility of the rotating ring plate can be controlled.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The diagram shown is a structural schematic of a cross rail connection and fixing device according to an embodiment of the present invention, comprising: Support base 1; Support plate 3, the array of support plates 3 is set at the bottom of support base 1; The rotating ring plate 5 is movably placed on top of the support plate 3, and a groove 6 is provided in the middle. The first protrusion 4 is fixedly installed in the middle of the support plate 3 and slidably disposed inside the slide groove 6. Support rod 15, the support rod 15 is arranged in a circumferential array on the inner side of the slide groove 6, and a positioning frame 7 is fixedly installed on the inner side; The slide rail 8 is movably set inside the positioning frame 7, and a cross guide rail body 9 is slidably set inside it; The limiting plate 22 is movably hinged to the outside of the lower support rod 15, and a second through groove 21 is provided on its surface. The limiting structure is set on the surface of the upper and lower end support rods 15 and is movably inserted into the second through groove 21 to limit the outer side of the positioning frame 7.

[0020] In this embodiment of the utility model, when in use, by symmetrically setting limiting structures at the upper and lower ends of the support rod 15 on the surface of the rotating ring plate 5, the position of the limiting plate 22 at either end can be fixed, thereby allowing the outer side of the positioning frame 7 in the middle of the rotating ring plate 5 to be abutted and limited. Thus, when placing the cross guide rail body 9, the slide rail 8 can be quickly inserted, and the positioning frames 7 on both sides can be limited, thereby facilitating the flipping of the slide rail 8.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, a positioning structure is movably provided on the top of the rear side of the left end support base 1. The positioning structure includes a pressure plate 10 and a slot 12. The pressure plate 10 is movably hinged to the top of the rear side of the support plate 3, and a limiting toothed ring 11 is fixedly installed at the bottom and movably inserted into the slide groove 6. The slot 12 is opened on the front side of the left end support plate 3. A positioning unit is movably provided on the front side of the pressure plate 10 and movably inserted into the slot 12.

[0022] In this embodiment of the utility model, when in use, the insert 14 is separated from the slot 12 on the side of the support plate 3 by the movable rod 13, so that the pressure plate 10 can be opened, thereby releasing the constraint of the limiting toothed ring 11 on the sliding groove 6 in the middle of the rotating ring plate 5, so that the rotating ring plate 5 can be rotated. By setting a positioning structure, the angle of the rotating ring plate 5 can be fixed after adjusting the angles of the upper and lower ends of the slide rail 8 of the cross guide rail body 9, which facilitates the installation and fixing of bolts, and thus allows for the quick connection and fixing of the cross guide rail body 9 and the slide rail 8.

[0023] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, in a preferred embodiment of this utility model, the limiting structure includes a first through groove 16, a guide rod 17, a limiting rod 18, a spring 19, and a limiting block 20. The first through groove 16 is arrayed on the surface of the upper and lower end support rods 15. The guide rod 17 is fixedly installed in the middle of the first through groove 16. The limiting rod 18 is symmetrically arranged at the upper and lower ends of the first through groove 16 and is slidably disposed on the surface of the guide rod 17. The limiting block 20 is fixedly installed on the outer end of the limiting rod 18 and is movably inserted into the first through groove 16. The spring 19 is movably sleeved on the surface of the guide rod 17 and movably abuts against the inner side of the limiting rod 18.

[0024] In this embodiment of the utility model, when in use, the slide rail 8 is inserted into the positioning frame 7 in the middle of the rotating ring plates 5 at both ends, and then the limiting rod 18 is pressed, so that the limiting rod 18 overcomes the elasticity of the spring 19 and closes along the guide rod 17, thereby making the cross section of the limiting block 20 at the outer end of the limiting rod 18 smaller than the cross section of the second through groove 21 and the first through groove 16, so that the limiting plate 22 at the lower end can be rotated upward and then abut against the limiting block 20 at the upper end, so that the limiting plate 22 is snapped at the upper end and limits the side of the positioning frame 7 at either end, so that when the cross guide rail body 9 is placed, it can abut against the limiting plate 22; By setting a limiting structure, the outer side of the positioning frame 7 can be limited, thereby facilitating the assembly of the cross rail body 9.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, the positioning unit includes a movable rod 13 and an insert block 14. The movable rod 13 is movably hinged to the bottom of the front side of the pressure plate 10, and the insert block 14 is fixedly installed on the inner side of the movable rod 13 and movably inserted into the slot 12.

[0026] In this embodiment of the utility model, when in use, the insert block 14 on the inner side of the lower end of the movable rod 13 is movably inserted into the slot 12, thereby constraining and fixing the pressure plate 10, so that the limiting toothed ring 11 is tightly inserted into the sliding groove 6 and is not easy to move.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment of the present invention, the cross-sectional size of the limiting tooth ring 11 is equal to the cross-sectional size of the slide groove 6, and the surface of the slide groove 6 is provided with tooth grooves, which are correspondingly arranged with respect to the limiting tooth ring 11.

[0028] In this embodiment of the utility model, when in use, the cross-sectional size of the limiting toothed ring 11 is made equal to the cross-sectional size of the slide groove 6, so that the limiting toothed ring 11 can be easily inserted into the slide groove 6. The slide groove 6 is provided with toothed grooves on its surface, which are corresponding to the limiting toothed ring 11, thereby facilitating the limiting and fixing of the rotation direction of the slide groove 6.

[0029] like Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, in a preferred embodiment of the present invention, the limiting plate 22 is a cross-shaped limiting plate, and the position of the first through groove 16 on the surface of the limiting plate 22 is set corresponding to the position of the upper and lower limiting structures.

[0030] In this embodiment of the utility model, when in use, by adopting a cross-shaped limiting plate 22, the outer side of the positioning frame 7 can be limited by the limiting plate 22, and by setting the position of the first through groove 16 on the surface of the limiting plate 22 to correspond to the positions of the upper and lower limiting structures, the limiting plate 22 can be fixed in different states.

[0031] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, a sliding rod 2 is fixedly installed at the rear end of the support base 1 and is movably inserted into the rear side of the lower end of the support plate 3. A manual bidirectional screw 23 is movably provided on the front side of the support base 1 and is movably connected to the front side of the lower end of the support plate 3.

[0032] In this embodiment of the utility model, when in use, a sliding rod 2 is fixedly installed at the rear end of the support base 1 and is movably inserted into the rear side of the lower end of the support plate 3, thereby facilitating the support plate 3. A manual bidirectional screw 23 is movably provided on the front side of the support base 1 and is movably connected to the front side of the lower end of the support plate 3, thereby facilitating the adjustment of the spacing between the two support plates 3, thus facilitating the assembly of cross rail bodies 9 of different lengths.

[0033] The present invention provides a cross rail connection and fixing device in the above embodiments. When in use, the slide rail 8 is inserted into the positioning frame 7 in the middle of the rotating ring plate 5 at both ends. Then, the limiting rod 18 is pressed, so that the limiting rod 18 overcomes the elasticity of the spring 19 and closes along the guide rod 17. This makes the cross section of the limiting block 20 at the outer end of the limiting rod 18 smaller than the cross section of the second through groove 21 and the first through groove 16, thereby facilitating the rotation of the limiting plate 22 at the lower end upward. This allows the limiting plate 22 to abut against the upper limiting block 20, so that the limiting plate 22 is snapped onto the upper end and limits the side of either end positioning frame 7, so that when the cross guide rail body 9 is placed, it can abut against the limiting plate 22. Then the other end limiting plate 22 is operated in the same way, so as to facilitate the limiting of both ends of the slide rail 8 on which the cross guide rail body 9 is placed. Subsequently, the insert 14 is separated from the slot 12 on the side of the support plate 3 by the movable rod 13, which allows the pressure plate 10 to open, thereby releasing the limiting toothed ring 11 from the constraint of the sliding groove 6 in the middle of the rotating ring plate 5. This allows the rotating ring plate 5 to rotate, adjusting the upper and lower ends of the slide rail 8 of the cross guide rail body 9, thus facilitating the installation and fixing of bolts, and quickly completing the connection and fixing of the cross guide rail body 9 and the slide rail 8.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
