The front end of the support frame 51 is fixedly connected to the inner wall of the protective cover 2. The inner wall of the support frame 51 is slidably connected to a right baffle 52 near the right end for closing the side opening of the protective cover 2. The inner wall of the support frame 51 is slidably connected to a left baffle 53 near the left end. The side opening of the protective cover 2 can be closed by cooperating with the left baffle 53 and the right baffle 52, thereby preventing stones and other debris from entering the interior of the protective cover 2. The front end of the protective cover 2 is provided with a wiring hole 22 for the passage of the line, and the rear end of the fixing plate 4 is provided with a fixing hole 42 for fixing the fixing plate 4. The fixing plate 4 can be fixed to a specific mounting surface by using a bolt to pass through the fixing hole 42.

[0031] Reference Figure 1 - Figure 3The outer wall of the cover plate 1 is fixedly connected to a connecting block 11 near the bottom end for fixing the cover plate 1, and the inner wall of the protective cover 2 is provided with a connecting hole 21 for accommodating the connecting block 11. The connecting block 11 is arranged as a right triangle with the inclined surface facing downward. When the inclined surface is squeezed, the connecting block 11 will squeeze the cover plate 1 to cause it to deform, and the connecting block 11 and the connecting hole 21 are adapted. When the connecting block 11 is stuck in the interior of the connecting hole 21, the connecting block 11 will contact the interior of the connecting hole 21 with a plane. At this time, the connecting block 11 will not be able to move upward and out of the interior of the connecting hole 21, so that the cover plate 1 will be fixed to the top end of the protective cover 2. There are multiple groups of connecting blocks 11 and connecting holes 21, and another group of connecting blocks 11 is fixedly connected to the outer wall of the protective cover 2 near the bottom end, and another group of connecting holes 21 is arranged on the inner wall of the bottom plate 3. Another group of connecting blocks 11 and connecting holes 21 can be used to connect the bottom plate 3 and the protective cover 2. At the same time, multiple groups of protective covers 2 can also be connected to each other through the connecting holes 21 and the connecting blocks 11.

[0032] Reference Figure 2 - Figure 4 , the top of the cover plate 1 is provided with a limiting groove 13 for accommodating the fixing plate 4, and the limiting groove 13 is set in a cross shape. When the fixing plate 4 is inserted into the limiting groove 13, the fixing plate 4 will be fixed and cannot rotate horizontally. The cross-shaped limiting groove 13 can adapt to fixing in various fixing directions. The top of the cover plate 1 is provided with a threaded groove 12 for installing a bolt, and the bottom end of the fixing plate 4 is provided with a positioning hole 41 for fixing the fixing plate 4. The threaded groove 12 and the positioning hole 41 are adapted to each other. By using a bolt to pass through the positioning hole 41 and screwing the bolt into the inside of the threaded groove 12, the fixing plate 4 can be fixed to the inside of the limiting groove 13. There are multiple groups of limiting grooves 13 and threaded grooves 12, and another group of limiting grooves 13 , a threaded groove 12 is provided at the bottom end of the base plate 3, and a group of fixing plates 4 can also be installed at the bottom end of the base plate 3, so that the entire device can be fixed from both ends. The inner wall of the support frame 51 is provided with a protrusion 56 for limiting the moving range of the left baffle 53 and the right baffle 52. The rear end of the right baffle 52 is fixedly connected with a buckle 54 for connecting the left baffle 53 and the right baffle 52. The rear end of the left baffle 53 is provided with a slot 55 for accommodating the buckle 54. The buckle 54 and the slot 55 are adapted to each other. The buckle 54 is made of plastic material, has elastic deformation ability and has a triangular front end. When the buckle 54 is inserted into the inside of the slot 55, the left baffle 53 and the right baffle 52 will be fixed and cannot be separated.

[0033] Working principle: When it is necessary to fix the line connector, the line connector can be placed inside the protective cover 2 first, and then the buckle 54 can be toggled to disengage it from the inside of the card slot 55. At this time, the right baffle 52 and the left baffle 53 can be separated to expose the wiring hole 22 on the side of the protective cover 2. Then, the connector and the line can be connected through the wiring hole 22. When it is necessary to increase the internal space of the device, multiple sets of protective covers 2 can be spliced ​​together by plugging with the help of the connecting block 11 and the connecting hole 21, so that the internal space of the device can be increased.

[0034] When the protective cover 2, joints and lines are adjusted, the top and bottom openings of the protective cover 2 can be closed using the cover plate 1 and the bottom plate 3. Then the fixing plate 4 can be inserted into the limiting groove 13 and the fixing plate 4 and the cover plate 1 can be fixed together using bolts passing through the positioning holes 41. The bottom plate 3 and the fixing plate 4 at its bottom can also be installed in the same way. When the two sets of fixing plates 4 are fixed, two sets of bolts can be used to fix the entire device to the outside of the wall to achieve the positioning of the entire device.
