[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

A fixed baffle 2 is welded to one side of the fixed seat 1, and a driving motor 3 is provided on one side of the fixed baffle 2, and the output shaft of the driving motor 3 is fixedly connected to a rotating screw 4 through a coupling, and the end of the rotating screw 4 is rotatably connected to the fixed baffle 2, the end outer wall of the rotating screw 4 is fixedly connected to a limiting ring 5, and the limiting ring 5 is engaged and rotatably connected with the fixed baffle 2, the sliding block 6 is rotatably connected to the outside of the rotating screw 4 through a thread, and the outside of the sliding block 6 is engaged and slidably connected to the limiting member 7, the bottom of the limiting member 7 is welded to the fixed seat 1, and one end of the limiting member 7 is fixedly connected to the fixed baffle 2, and the end of the limiting member 7 is provided with a blocking group Part 8, and the blocking assembly 8 includes a movable baffle 801, a limiting rod 802, a square block 803 and a rotating block 804, the movable baffle 801 contacts the limiting part 7 and the end of the fixed seat 1, and the end of the rotating screw 4 is engaged and rotatably connected with the movable baffle 801, a limiting rod 802 is welded on one side of the movable baffle 801, and a slot is opened at the center of the end of the rotating screw 4, and the limiting rod 802 is engaged and rotatably connected with the rotating screw 4 through the slot, square blocks 803 are welded on both sides of the end of the limiting part 7 and the fixed seat 1, and the square block 803 is connected with the movable baffle 801 through, and one side of the square block 803 is rotatably connected with the rotating block 804 through the damping shaft, and the rotating block 804 is fixed to the movable baffle 801 by bolts;

[0023] The specific operation is as follows: the staff uses the driving motor 3 to drive the rotating screw 4 to rotate, so that the sliding block 6 connected to the outside of the rotating screw 4 by threaded rotation gradually engages and slides on the inner side of the limit piece 7. When the sliding block 6 is subsequently maintained, the staff can release the fixing of the movable baffle 801 by the bolts on the surface of the rotating block 804, and use the damping shaft to rotate the rotating block 804, so that the rotating block 804 rotates to a horizontal state, and then removes the movable baffle 801 to the outside, and makes the limit rod 802 welded on one side of the movable baffle 801 gradually detach from the end of the rotating screw 4. Subsequently, as the rotating screw 4 continues to rotate, the sliding block 6 gradually slides out from the end of the limit piece 7, thereby facilitating the staff to maintain the sliding block 6. The structure is simple and convenient for the staff to use the linear guide rail.

[0024] like Figure 1 and Figure 3 As shown, the support plate 9 is fixedly connected to the top of the sliding block 6, and a ball 10 is provided inside the support plate 9, the outer wall of the ball 10 is in contact with the top of the limiter 7, and an oil injection channel 11 is provided above the ball 10, and the four corners of the bottom of the support plate 9 are fixedly connected to support members 12, and the bottom inner side of the support member 12 is rotatably connected to a rolling wheel 13, and a limiting strip 14 is provided below the rolling wheel 13, and the limiting strip 14 is welded to both sides of the top of the fixing seat 1, and the side of the limiting strip 14 is fixedly connected to the side bottom of the limiter 7;

[0025] The specific operation is as follows: during the movement of the sliding block 6, the support plate 9 fixedly connected to the top of the sliding block 6 slides on the top of the limiter 7, and the ball 10 arranged inside the support plate 9 is used to make the relative movement of the support plate 9 and the limiter 7 smoother, and the staff can use the oil injection channel 11 to inject lubricating oil into the surface of the ball 10, so that the surface of the ball 10 is protected by the lubricating oil, thereby improving the wear resistance of the linear guide rail and facilitating the use of the linear guide rail by the staff.

[0026] In summary, the linear guide with good wear resistance is Figure 1-Figure 3, in the process of using the linear guide rail, first, the staff uses the driving motor 3 to drive the rotating screw 4 to rotate, so that the sliding block 6 connected to the outer side of the rotating screw 4 by threaded rotation gradually engages and slides on the inner side of the limit member 7, and then the staff can release the bolts on the surface of the rotating block 804 to fix the movable baffle 801, and use the damping shaft to rotate the rotating block 804, so that the rotating block 804 rotates to a horizontal state, and then removes the movable baffle 801 to the outside, and makes the limit rod 802 welded on one side of the movable baffle 801 gradually separate from the end of the rotating screw 4. Subsequently, as the rotating screw rod 4 continues to rotate, the sliding block 6 gradually slides out from the end of the limit piece 7, which makes it easier for the staff to maintain the sliding block 6. In addition, during the movement of the sliding block 6, the support plate 9 fixedly connected to the top of the sliding block 6 slides on the top of the limit piece 7. The ball 10 arranged inside the support plate 9 makes the relative movement of the support plate 9 and the limit piece 7 smoother, and the staff can use the oil injection channel 11 to inject lubricating oil into the surface of the ball 10, so that the surface of the ball 10 is protected by the lubricating oil, which makes it convenient for the staff to use the linear guide rail.
