In the prior art, the sliding door on the cover usually uses a pulley in conjunction with a track to allow the sliding door to be horizontally displaced. However, the gap between the pulley and the track is large, which may cause dust and impurities to enter the cover, and is not suitable for use. In addition, the pulley and the track will sway left and right during the horizontal pulling process, and the structure is unstable. At the same time, the pulley in conjunction with the track requires more components, has a higher cost, and is difficult to install and disassemble. Summary of the invention

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 3As shown, the frame is formed by several frame profiles 1 being enclosed and spliced ​​together, including a top frame with a rectangular top and side frames with downward sides of the top, the side frames are provided with protective plates 2, the side frames and the top frame are enclosed into a cover body, the conveyor line body can pass through the cover body, which plays a protective role for the conveyor line body, the fixed door panel 3 is placed on the top frame, the fixed door panel 3 is a rectangular plate, the material is a metal plate, in some embodiments, it can also be a transparent acrylic plate, which is convenient for observing the inside, the two ends of the fixed door panel 3 are fixedly connected to the frame profiles 1 at both ends of the top frame through the first profile 4, the movable door panel 5 is a rectangular plate, which can be a metal plate, in some embodiments, it can also be a transparent acrylic plate, which is convenient for observing the inside, and the two ends of the movable door panel 5 are fixedly provided with a second profile 6, the length direction of the second profile 6 is the same as the length direction of the first profile 4, and both are also the conveying direction of the conveyor line body. The second profile 6 is connected with the first profile 4 by sliding cooperation, and the movable door panel 5 can be horizontally moved back and forth along the length direction of the first profile 4. The horizontal height of the movable door panel 5 is higher than the horizontal height of the fixed door panel 3, and the fixed door panel 3 will not interfere with the position of the movable door panel 5 in motion. When the movable door panel 5 is placed in the first preset position, that is, the fixed door panel 3 and the movable door panel 5 completely cover the top frame, the frame is in a closed state at the upper end, and the conveyor line body in the frame is protected. When the movable door panel 5 slides to the second preset position, or leaves the first preset position, the movable door panel 5 at least partially moves to the top of the fixed door panel 3, and the frame is in a semi-closed state at the top, and the position where the movable door panel 5 moves out forms an upward opening, which is convenient for the staff to operate or repair the conveyor line body in the frame. Compared with the pulley rail matching method used in the prior art, the sliding cooperation of the first profile 4 and the second profile 6 is adopted, the structure is simple, and there will be no excessive gap. The first profile 4 and the second profile 6 can be stocked in batches and cut to length according to actual needs, which is low in cost.

[0026] In some embodiments, Figure 3 and Figure 4 As shown, the first profile 4 includes a door panel connecting portion 401, and the two ends of the fixed door panel 3 are respectively fixedly connected to the door panel connecting portions 401 of the first profile 4 on both sides. The height of the fixed door panel 3 is lower than the height of the frame profile 1 at the upper end of the frame, that is, the door panel connecting portion 401 adopts a sunken design relative to the top frame, thereby avoiding the sliding travel range of the movable door panel 5.

[0027] In some embodiments, Figure 3 and Figure 4As shown, the door panel connecting portion 401 includes a mounting portion 4011 opening upward, and the mounting portion 4011 may be a trapezoidal groove. Preset holes in the vertical direction may be opened at both ends of the fixed door panel 3, and bolts pass through the preset holes at both ends of the fixed door panel 3 and are detachably connected to the trapezoidal groove, that is, the fixed door panel 3 is placed in the door panel connecting portion 401 from the vertical direction, and the installation and disassembly of the fixed door panel 3 can be completed by tightening the bolts or unscrewing the bolts.

[0028] In some embodiments, Figure 3 and Figure 4 As shown, the first profile 4 also includes a frame connection part 402, and the frame connection part 402 is fixedly connected to the upper end surface of the frame profile 1 of the top frame. The installation between the first profile 4 and the top frame can be completed by a fixing part. The door panel connection part 401 is away from the frame profile 1 relative to the frame connection part 402, and the horizontal height of the door panel connection part 401 is lower than the height of the frame connection part 402, ensuring that the height of the fixed door panel 3 after installation is lower than the movable door panel 5, thereby not interfering with the movement of the movable door panel 5.

[0029] In some embodiments, Figures 3 to 5 As shown, the first profile 4 also includes a profile guide portion 403, which is placed at a relative position above the frame connecting portion 402. The length direction of the profile guide portion 403 is the same as the length direction of the first profile 4. The profile guide portion 403 has a protruding structure protruding from the upper surface of the frame connecting portion 402. A downwardly opening groove portion 601 is provided at a corresponding position of the second profile 6. The groove portion 601 can accommodate the profile guide portion 403. The profile guide portion 403 and the groove portion 601 are slidably connected with each other, so that the second profile 6 can be horizontally moved back and forth relative to the first profile 4 along the length direction of the first profile.

[0030] In some embodiments, Figure 3 and Figure 6 As shown, the friction strip 7 includes a buckle part 701 with an opening at the bottom and a friction guide part 702 with an arc shape at the upper end, wherein the buckle part 701 can cover both sides of the profile guide part 403 and buckle with the bottom end of the profile guide part 403 to limit the position, and the friction guide part 702 covers the top of the profile guide part. The friction strip 7 is made of metal material, which is wear-resistant and does not generate dust due to friction. The top of the friction guide part 702 of the friction strip 7 contacts the groove part 601 to form a line-surface contact, reduce friction resistance, and improve the relative friction smoothness of the second profile relative to the first profile. The friction strip 7 can be inserted and limited along the length direction of the profile guide part 403 to facilitate installation.

[0031] In some embodiments, Figure 3 and Figure 6As shown, the friction strip 7 also plays a supporting role. After the friction strip 7 is installed, the friction guide rail portion 702 lifts the second profile 6 to a certain height, and the opposing surfaces of the first profile 4 and the second profile 6 are spaced apart, so that the opposing surfaces of the first profile 4 and the second profile 6 will not come into contact, further reducing the friction.

[0032] In some embodiments, Figure 1 As shown, a handle 8 is provided on the upper surface of the movable door panel, and the handle is adapted to be pulled in the horizontal direction, so as to facilitate the change of the horizontal position of the movable door panel.

[0033] In some embodiments, Figure 1 As shown, a handle 9 is provided on the upper surface of the fixed door panel, and the handle is adapted to be pulled in the vertical direction. The fixed door panel can be placed in and lifted from the vertical direction by the handle, so as to facilitate the installation and removal of the fixed door panel.
