The effect of the present invention is that the hook and pull member of the slider device is used to hook the groove of the track, so that the sliding seat can be prevented from being separated from the track during the sliding process. Therefore, the present invention can improve the smoothness of use.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are designated by the same reference numerals.

2 to 4, the first embodiment of the protective cover of the present invention is suitable for slidably mounted on two parallel and spaced rails 9, and is used to shield the machining chips generated during the operation of the machine tool. Each of the rails 9 extends along a front-rear direction X and has two grooves 91 extending along the front-rear direction X. The grooves 91 are spaced apart in a left-right direction Y. Each of the rails 9 is aluminum extrusion and the The equal grooves 91 are formed on the left and right side surfaces, respectively. The protective cover includes a number support bar 2 , a number slider device 300 and a number mask 4 .

The support bars 2 are arranged at intervals along the front-rear direction X and located between the rails 9 , each of the support bars 2 is extruded aluminum and extends along the left-right direction Y.

Referring to FIG. 4 to FIG. 6 , the slider devices 300 are disposed on the left and right ends of each of the support bars 2 in pairs and are slidably disposed on the rails 9 . Each of the slider devices 300 includes a connecting seat 5 , a sliding seat 6 and an engaging piece 7 . The connecting seat 5 is connected to the top surface of one end of the corresponding support bar 2 in a top-bottom direction Z. The connecting seat 5 extends along the left-right direction Y and one end protrudes from the corresponding support bar 2. The connecting seat 5 One end of 5 has a long guide groove 51 extending along the left-right direction Y.

The sliding seat 6 is disposed on the bottom side of one end of the connecting seat 5 and adjacent to the corresponding support bar 2 , and the sliding seat 6 is slidably disposed on the corresponding rail 9 . The sliding seat 6 has a main body 61 , two rollers 62 and two hook and pull groups 63 . The seat body 61 defines a mounting space 60 for the corresponding rail 9 to pass through. The seat body 61 has a base 611 higher than the rail 9 in the top-bottom direction Z and abutting against the connecting seat 5 , two side portions 612 extending downward from the left and right ends of the base portion 611 respectively, and a convex portion 613 extending upward from the base portion 611 and slidably accommodated in the long guide groove 51 of the connecting seat 5 . Each of the side portions 612 is formed with a mounting groove 614 . The rollers 62 extend along the left-right direction Y and are rotatably disposed in the installation space 60 and between the base 611 and the rail 9 . The slider device 300 can slide back and forth along the rails 9 . In some embodiments, the number of the rollers 62 can also be one.

In addition, in the first embodiment, the protrusion 613 is slidably accommodated in the long guide groove 51 . When the parallelism of the rails 9 is not good, the sliding seat 6 can be left or right relative to the connecting seat 5 displacement, so that the slider devices 300 can smoothly slide along the rails 9 .

Referring to FIG. 5 to FIG. 7 , the hook-and-pull groups 63 are respectively disposed in the installation grooves 614 of the base body 61 and hooked and pulled in the grooves 91 respectively. Each of the hook-and-pull sets 63 has a hook-and-pull member 631 rotatably pivoted on the seat body 61 , an elastic member 632 that springs against the seat body 61 and the hook-and-pull member 631 , and a hook-and-pull member 632 passing through the seat body 61 . The hook 631 and the pivot 633 of the seat body 61 . The pulling member 631 is slidably hooked to the groove 91 . The pulling member 631 has a hook portion 634 for pulling the groove 91 , a main body 635 for the hook portion 634 , and two The main body 635 extends upward from the front and rear sides of the main body 635 and is pivotally connected to the pivot portion 636 of the seat body 61 . The elastic member 632 has the potential energy that keeps the hook portion 634 hooked to the groove 91 . The elastic member 632 of the first embodiment is a torsion spring and has a first end 637 that springs against the seat body 61 . and a second end 638 opposite to the first end 637 and springing against the main body 635 of the hook and pull member 631 . The pivot shaft 633 extends along the front-rear direction X, and the elastic member 632 is sleeved and passed through the pivot portions 636 and the side portion 612 of the seat body 61 .

The engaging piece 7 is higher than the long guide groove 51 and is screwed to the protruding portion 613 . The shape of the engaging piece 7 is larger than that of the long guide groove 51 . In the first embodiment, the engaging piece 7 is a rectangular piece And the width is larger than the width of the long guide groove 51 , the seat body 61 is mounted on the connecting seat 5 by the joint piece 7 , and the disassembly method is more convenient. In some embodiments, each slider device 300 can also omit the engaging piece 7 , and make the convex portion 613 of the sliding seat 6 form a stepped shape with a wide upper and a narrow lower, and then be installed in the sliding seat 6 at an angle. The long guide groove 51 also enables the sliding base 6 to be installed on the connecting base 5 and can be displaced left and right relative to the connecting base 5 .

The seat body 61 also has at least one action portion 615 formed on the top surface of the base portion 611 . As shown in FIG. 7 , the action portion 615 in the first embodiment is a groove and the number of the action portion 615 is two. The acting parts 615 are used to reduce the sliding friction between the bottom surface of the connecting seat 5 and the top surface of the base part 611 . However, in other variations, each of the acting parts 615 can also be a protruding strip, a convex point or a frosted structure, as long as the contact area between the connecting seat 5 and the seat body 61 can be reduced or a gap can be formed between the two, Therefore, the displacement of the seat body 61 relative to the connecting seat 5 can be made smoother.

Referring to FIG. 2 , the shutters 4 can be unfolded or folded and are disposed on the support bars 2 . Each of the shutters 4 in the first embodiment is W-shaped and connected to two support bars 2 . The support bars 2 are moved back and forth along the rails 9 by the slider devices 300 , so that the shutters 4 are unfolded or folded, which can be used to shield the machining chips generated during the operation of the machine tool.

Referring to FIG. 8 , the present invention utilizes the hooks and pulls 631 of the slider device 300 to pivot on the base body 61 rotatably. When the slider device 300 is installed on the rail 9 , the hooks and pulls 631 The hooks 634 will be pushed open by the outer surface of the rail 9 and pivot outward until the hooks 634 of the hooks 631 drop to the positions of the grooves 91, as shown in FIG. 4 , the The hooks 634 of the hook-pulling members 631 are pushed toward the grooves 91 by the elastic members 632 to be positioned in the grooves 91 . After the hooks 634 are pulled by the grooves 91 , The sliding seat 6 can be prevented from being separated from the track 9 during the sliding process, so the present invention can improve the smoothness of use.

Referring to FIG. 9 and FIG. 10 , the second embodiment of the present invention is similar to the first embodiment, and the difference lies in:

The number of the installation grooves 614 of the sliding seat 6 of each slider device 300 is one, and the installation grooves 614 are formed on the side portion 612 farther from the support bar 2 .

Each slider device 300 has one hook-and-pull group 63 , and the hook-and-pull group 63 is rotatably pivoted to the installation groove 614 of the base body 61 . The second embodiment can also prevent the sliding bases 6 from disengaging from the rails 9 during the sliding process, and has the same function as the first embodiment.

However, the above are only examples of the present invention, and should not limit the scope of implementation of the present invention. Any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the patent specification are still included in the scope of the present invention. within the scope of the invention patent.
