DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] For example, see Figure 1-4, a retaining plate for protecting a building foundation pit comprises a bottom plate 1, the bottom plate 1 is rotatably connected with a baffle plate 2, an angle adjustment device 3 is arranged inside the baffle plate 2, a positioning plate 4 is fixedly connected to the right side of the baffle plate 2, a slide groove 5 is provided on the left side of the baffle plate 2, a fixing plate 6 is fixedly connected to the left side of the baffle plate 2, a bolt 7 is threadedly connected to the fixing plate 6, a threaded hole 8 is provided on the right side of the baffle plate 2, a buffer assembly 9 is arranged at one end of the baffle plate 2 away from the angle adjustment device 3, a fixing piece 10 is arranged inside the bottom plate 1, the angle adjustment device 3 comprises a fixing strip a31, the fixing strip a31 is rotatably connected to the inner wall of the bottom plate 1, the fixing strip a31 is slidably connected to the fixing strip b32, a bayonet 33 is provided on the inner wall of the fixing strip a31, a limiting strip 34 is slidably connected to the inner wall of the fixing strip b32, a slideway is provided on the side wall of the fixing strip b32 away from the bottom plate 1, and the limiting strip 34 is fixedly connected to a control block located inside the slideway, and the setting of the slideway allows the staff to conveniently control the control block through the control block The movement of the limit bar achieves the expected effect. The end of the limit bar 34 away from the bayonet 33 is fixedly connected to a spring 35. The end of the spring 35 away from the limit bar 34 is fixedly connected to the inner wall of the fixing bar b32. The inner wall of the limit bar 34 is fixedly connected to a block 36. The inner wall of the fixing bar b32 is provided with a through hole 37 that matches the position of the block 36. The fixing bar b32 is rotatably connected to a mounting block 38. The outer wall of the mounting block 38 is provided with a circular hole, and the swivel 39 is connected to the inner wall of the fixing bar b32. The through hole passes through the inner wall of the mounting block 38. By setting the position of the swivel, the staff can conveniently rotate the swivel and ensure that other functions of the mounting block are not affected. The mounting block 38 is rotatably connected to the swivel 39, and the mounting block 38 is slidably connected to the plug block 310. The swivel 39 is provided with a movable hole, and the plug block 310 is slidably connected to the swivel 39 through the movable hole. A connecting block 311 is fixedly connected to the outer wall of the baffle 2, and a plug hole 312 is provided on the inner wall of the connecting block 311.
[0020] When in use, the staff first rotates the baffle 2 so that the baffle 2 does not contact the surface of the bottom plate 1, then the staff rotates the fixing strip a31 from the inner wall of the bottom plate 1, and then places the mounting block 38 inside the connecting block 311, and then the staff rotates the swivel 39 so that the swivel 39 drives the plug-in block 310 to move through the moving hole during the rotation, so that the plug-in block 310 moves outward and enters the inside of the insertion hole 312, so that the mounting block 38 and the connecting block 311 are in a relatively fixed state. When the fixing is completed, the staff presses the control block on the limit strip 34 toward the side close to the spring 1 35 so that the limit The bar 34 drives the block 36 to move in the direction away from the bayonet 33. When the block 36 moves to a position that is not in the same plane as the bayonet 33, the staff changes the maximum distance between the fixing bar b32 and the fixing bar a by pulling the fixing bar b32, thereby changing the rotation angle of the baffle 2 by changing the total length of the fixing bar a31 and the fixing bar b32. When it is rotated to a suitable angle, the staff stops pressing the control block, so that the limit bar 34 is automatically reset under the drive of the spring 1 35, so that the block 36 enters the bayonet 33, so that the fixing bar a31 and the fixing bar b32 are in a relatively fixed state.
[0021] For example 2, please refer to Figure 1-4 On the basis of the first embodiment, the buffer assembly 9 includes a buffer plate 91, the size and shape of the buffer plate 91 are consistent with the baffle 2, and a rubber coating is provided on the side of the buffer plate 91 away from the baffle 2. The consistent shape ensures that the buffer plate can protect a larger area, and the setting of the rubber coating ensures that the surface of the buffer plate has a certain buffering effect and can protect itself. The buffer plate 91 is hinged with a connecting rod 92, and the connecting rod 92 is hinged with a moving block 93. The moving block 93 is slidably connected with a fixed rod 94. The shape of the fixed rod 94 is a cylinder, and the outer wall of the fixed rod 94 and the interior of the moving block 93 are smooth. By setting the shape and smoothness of the fixed rod, it is ensured that the friction force on the moving block during the movement is small, preventing the moving block from being unable to automatically reset. The fixed rod 94 is fixedly connected with a fixed block 95, and the fixed block 95 is fixedly connected to the baffle 2. The end of the moving block 93 close to the fixed block 95 is fixedly connected with a spring 2 96, and the end of the spring 2 96 away from the moving block 93 is fixedly connected to the outer wall of the fixed block 95.
[0022] During use, on the basis of Example 1, when debris hits the baffle plate 2, since the size of the buffer plate is consistent with that of the baffle plate 2, the debris will first hit the buffer plate 91. When the buffer plate 91 is hit, the buffer plate 91 moves in the direction close to the baffle plate 2, thereby driving the side of the connecting rod 92 close to the buffer plate 91 to move in the direction close to the baffle plate 2, so that the connecting rod 92 pushes the moving block 93, so that the moving block 93 moves in the direction close to the fixed block 95. At this time, the spring 96 is squeezed, and the rebound force generated by the spring 96 causes the moving block 93 to generate a force to move toward the side close to the connecting rod 92, so that the impact force of the debris is partially offset, thereby achieving a buffering effect.
[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
