The multiple fixing rods 204 are evenly divided into two groups, and one end of the two groups of fixing rods 204 is movably penetrated into the inside of the two first shielding plates 201. ;

[0028] The effect achieved by the entire embodiment 1 is that, when in use, the driving motor body 103 is started, and the rotational motion is transmitted to the screw body 104 through the coupling 106 to rotate, and then the moving block 107 is driven to move, and the slider body 105 is driven to move on the guide rail platform body 101. The linear reciprocating motion of the slider body 105 is realized by the driving of the driving motor body 103. With the cooperation of the two first shielding plates 201 and the second shielding plate 301, the components inside the guide rail platform body 101 are shielded to achieve a protective effect. When the second shielding plate 301 appears When the second shielding plate 301 is damaged and needs to be replaced, the four pulling blocks 209 are pulled outward to drive the corresponding fixing rods 204 to move outward, and the corresponding connecting springs 210 are stretched under tension, so that the fixing rods 204 are pulled out of the corresponding fixing grooves 306. At this time, the second shielding plate 301 loses its limit. Then, with the help of a tool, the pulling tool is inserted into the two L-shaped grooves 302 to remove the second shielding plate 301, so that it is convenient to replace the new second shielding plate 301. When a first shielding plate 201 is damaged and needs to be replaced, the two pulling blocks 209 at the first shielding plate 201 are pulled out. The two movable blocks 309 are then squeezed in opposite directions to make them move relative to each other, and the fixed sleeve 308 is driven to move relative to each other. At this time, the support spring 311 is squeezed and contracted, and the two fixed blocks 304 are driven to move relative to each other through the fixed sleeve 308, and leave the corresponding square hole 305. At this time, the support block 202 loses its limit position with the square hole 305. The mounting screws and adjusting bolts 207 at the first shielding plate 201 are unscrewed, and finally the first shielding plate 201 is pulled upwards to make the support block 202 and the square hole 305 lose their limit position. The support block 202 passes through the square hole 305, so that the first shielding plate 201 can be removed and replaced. The spliced ​​cover plate is realized by the first protective component 2 and the second protective component 3. When one of the cover plates is damaged, the corresponding cover plate can be removed without the need to disassemble the entire cover plate. The operation is simple, time is saved, and the cost of replacing the cover plate is reduced. This solves the problem that when the cover plate is partially damaged during the use of the shielded linear module, the cover plate needs to be completely disassembled, the operation steps are relatively complicated, the time cost is increased, and the cost of replacing the entire cover plate is relatively high.

[0029] Embodiment 2, as Figure 1-Figure 6As shown, two adjustment grooves 208 are provided on opposite sides of the two first shielding plates 201, and adjustment plates 205 are movably embedded inside the multiple adjustment grooves 208. Multiple adjustment holes 206 are provided on the tops of the multiple adjustment plates 205. Adjustment bolts 207 are threadedly embedded near the two sides of the tops of the two first shielding plates 201, and the outer surfaces of the multiple adjustment bolts 207 are movably embedded in four of the adjustment holes 206. The bottom ends of the multiple adjustment bolts 207 are threaded through the two first shielding plates 201 to the bottom, respectively. The multiple adjustment bolts 207 are evenly divided into two groups, and the bottom ends of the two groups of adjustment bolts 207 are threadedly embedded in the tops of the two end plates 102, respectively.

[0030] The effect achieved by the entire embodiment 2 is that, when in use, the adjusting bolt 207 is screwed out from the corresponding adjusting hole 206, and then the adjusting plate 205 is pulled outward; when the adjusting plate 205 is pulled to a suitable position, the adjusting bolt 207 is screwed into the adjusted adjusting hole 206 again, and further screwed into the connecting groove at the top of the end plate 102, and the adjusted adjusting plate 205 is fixed, thereby adjusting the width between the two first shielding plates 201 to adapt to slider bodies 105 of different widths; and then, according to the width between the two first shielding plates 201, a second shielding plate 301 of corresponding width is installed, thereby achieving the effect of adjusting the width, increasing flexibility, adapting to different slider bodies 105, and improving applicability.

[0031] Working principle: When the second shielding plate 301 is damaged and needs to be replaced, the four pulling blocks 209 are pulled outward to drive the corresponding fixing rods 204 to move outward, and the corresponding connecting springs 210 are stretched under tension, so that the fixing rods 204 are pulled out from the corresponding fixing grooves 306. At this time, the second shielding plate 301 loses its limit. Then, with the help of tools, the pulling tool is inserted into the two L-shaped grooves 302 to remove the second shielding plate 301, which is convenient for replacing a new second shielding plate 301. When one of the first shielding plates 201 is damaged and needs to be replaced, When changing, the two pulling blocks 209 at the first shielding plate 201 are pulled outward, so that the two fixing rods 204 there slide out of the fixing grooves 306, and then the two movable blocks 309 are pinched in relative directions to make them move relative to each other, and drive the fixing sleeve 308 to move relative to each other. At this time, the supporting spring 311 is squeezed and contracted, and drives the two fixing blocks 304 to move relative to each other through the fixing sleeve 308 and leave the corresponding square hole 305. At this time, the support block 202 loses its limit position with the square hole 305, and the mounting screws at the first shielding plate 201 are unscrewed. The first shielding plate 201 is finally pulled upwards so that the support block 202 passes through the square hole 305, and the first shielding plate 201 can be removed and replaced. The first protective assembly 2 and the second protective assembly 3 realize a spliced ​​shielding plate. When a certain shielding plate is damaged, the corresponding shielding plate can be removed without the need for disassembly of the entire shielding plate. The operation is simple, time is saved, and the replacement cost of the shielding plate is reduced. When in use, the adjusting bolt 207 is screwed out of the corresponding adjusting hole 206, and then the adjusting plate 205 is pulled outwards. When the adjusting plate 205 is adjusted, the adjusting bolt 207 is screwed out of the corresponding adjusting hole 206. When the section plate 205 is pulled to a suitable position, the adjusting bolt 207 is screwed into the adjusted adjusting hole 206 again, and further screwed into the connecting groove at the top of the end plate 102 to fix the adjusted adjusting plate 205, thereby adjusting the width between the two first shielding plates 201 to adapt to slider bodies 105 of different widths. Then, according to the width between the two first shielding plates 201, a second shielding plate 301 of corresponding width can be installed, thereby achieving the effect of adjusting the width, increasing flexibility, adapting to different slider bodies 105, and improving applicability.

[0032] The wiring diagram of the drive motor body 103 and the coupling 106 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the drive motor body 103 and the coupling 106 are no longer explained in detail.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
