Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, specifically to a corner mirror for road engineering. Background Technology

[0002] Road engineering is a branch of civil engineering, involving the entire process of road planning, surveying, design, construction, maintenance and management. The main contents of road engineering include road network planning, route surveying and design, roadbed engineering, pavement engineering, road drainage engineering, bridge and culvert engineering, tunnel engineering and ancillary facilities engineering, etc. Corner mirrors, also called wide-angle mirrors, convex mirrors or turning mirrors, are mainly used in various curves and intersections. They can expand the driver's field of vision and spot vehicles and pedestrians on the other side of the curve earlier to reduce traffic accidents. They are also used for supermarket anti-theft and monitoring blind spots.

[0003] However, when using existing corner mirrors for road engineering, workers typically use bolts to fix the main body of the corner mirror to the vertical frame. However, when adjusting the height of the corner mirror, it is necessary to remove the bolts on the outside of the corner mirror, then pull the corner mirror outside the vertical frame, and then fix it with bolts again after moving it to the appropriate position. The operation steps are cumbersome and have a certain impact on the installation efficiency of the corner mirror. At the same time, the corner mirror is directly exposed to the external environment, and dust and foreign objects in the external environment will adhere to the surface of the corner mirror, which will reduce the clarity of the corner mirror. Therefore, a new corner mirror for road engineering is needed. Utility Model Content

[0004] The main purpose of this utility model is to provide a corner mirror for road engineering. This utility model solves the problems of inconvenience in adjusting the height of the corner mirror body and cleaning dust and foreign objects from the surface of the corner mirror body during use by setting up a box, vertical frame, connecting plate, fixing plate, spring, through hole, rope chain, pulley, drive rod and fixing block.

[0005] The technical solution adopted by this utility model to solve its technical problem is a corner mirror for road engineering, including a corner mirror body. A shell for protecting the corner mirror body is fixed to the outside of the corner mirror body by screws. A fixing block is fixed to the outside of the shell by screws, and a rope chain for moving the fixing block is bolted to the top of the fixing block. A coil rod is fixed to the end of the rope chain away from the fixing block by screws, and a vertical frame for rotating the coil rod is provided on the outside of the coil rod. A drive rod for rotating the coil rod is inserted into the outside of the vertical frame, and a threaded sleeve for fixing the drive rod is threaded to the outside of the drive rod. A pulley for stabilizing the movement of the rope chain is fixed to the top of the vertical frame by screws. A box for collecting rainwater is bolted to the top of the vertical frame. A through hole for rainwater discharge is opened on the outside of the box. A fixing plate is slidably connected to the outside of the box, and a rubber block for sealing the through hole is fixed to one side of the fixing plate by screws. A spring is welded to the end of the fixing plate away from the rubber block. A connecting plate for moving the fixing plate is fixed to the top of the shell by screws. A fixing hole A is opened on the surface of the connecting plate, and fixing holes B are opened at the bottom of the connecting plate and the top of the shell.

[0006] By adopting the above technical solution, when the height of the corner mirror body needs to be adjusted, the threaded sleeve outside the drive rod is rotated to separate the threaded sleeve from the vertical frame, and then the drive rod is rotated, causing the winding rod on one side of the drive rod to drive the rope chain to wind up. Then the rope chain drives the fixed block to move through the pulley, and the fixed block drives the corner mirror body inside the housing to move. After the corner mirror body is adjusted to a suitable height, it is rotated to the threaded sleeve outside the drive rod, so that the threaded sleeve contacts the vertical frame and fixes the drive rod, thereby fixing the height of the corner mirror body, which makes it easy to adjust the height of the corner mirror body according to the needs.

[0007] The box at the top of the vertical frame collects rainwater. When the corner mirror body moves to its highest point, the connecting plate on the outer shell of the corner mirror body moves the fixing plate outside the box. Then the fixing plate presses the spring on one side, and the rubber block outside the fixing plate moves out of the through hole. The fixing hole A on the connecting plate connects with the through hole on the box body. Then the water inside the box flows into the connecting plate through the through hole and fixing hole A. Then the fixing holes B at the bottom of the connecting plate and the top of the shell allow the water to flow to the surface of the corner mirror body, which facilitates the washing of dust and foreign objects on the surface of the corner mirror body.

[0008] Specifically, a filter frame for filtering rainwater entering the box is fixed to the inside of the box with screws.

[0009] By adopting the above technical solution, when rainwater enters the box, the filter frame inside the box filters the rainwater. At the same time, the filter frame inside the box is disassembled and cleaned regularly to prevent the filter frame from becoming clogged.

[0010] Specifically, the outer side of the reel is symmetrically fitted with support blocks that limit the movement of the rope chain.

[0011] By adopting the above technical solution, when the reel is winding the rope chain, the support block outside the reel limits the rope chain and prevents the rope chain from shifting during winding.

[0012] Specifically, the fixed block is symmetrically welded with sliding sleeves on the outside, and a sliding rod is slidably connected to the inside of the sliding sleeves.

[0013] By adopting the above technical solution, when the fixed block drives the corner mirror body inside the housing to move, the sliding sleeve outside the fixed block slides outside the sliding rod, thereby improving the stability of the corner mirror body movement.

[0014] Specifically, a limiting groove is provided inside the box, and a limiting block connected to the fixing plate is slidably connected to the inner side of the limiting groove.

[0015] By adopting the above technical solution, when the fixed plate moves the rubber block, the limiting block outside the fixed plate slides in the limiting groove opened in the box, thereby improving the stability of the fixed plate moving the rubber block.

[0016] The beneficial effects of this utility model are:

[0017] (1) The corner mirror for road engineering described in this utility model, when the height of the corner mirror body needs to be adjusted, rotate the threaded sleeve outside the drive rod to separate the threaded sleeve from the vertical frame, and then drive the drive rod to rotate, so that the winding rod on one side of the drive rod drives the rope chain to wind up, and then the rope chain drives the fixed block to move through the pulley, and the fixed block drives the corner mirror body inside the housing to move. After the corner mirror body is adjusted to a suitable height, rotate to the threaded sleeve outside the drive rod so that the threaded sleeve contacts the vertical frame and fixes the drive rod, so that the height of the corner mirror body is fixed, thereby facilitating the adjustment of the height of the corner mirror body according to the needs.

[0018] (2) The corner mirror for road engineering described in this utility model has a box at the top of the vertical frame that collects rainwater. When the corner mirror body moves to the highest point, the connecting plate on the outer shell of the corner mirror body drives the fixing plate outside the box to move. Then the fixing plate presses the spring on one side, and then the rubber block outside the fixing plate moves out of the through hole. The fixing hole A on the connecting plate is connected to the through hole on the box. Then the water in the box flows into the connecting plate through the through hole and the fixing hole A. Then the fixing hole B at the bottom of the connecting plate and the top of the shell makes the water flow to the surface of the corner mirror body, thereby facilitating the washing of dust and foreign objects on the surface of the corner mirror body.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] In order to adjust the height of the corner mirror body 12 according to the needs, as an embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the corner mirror for road engineering of this utility model includes a corner mirror body 12. A housing 8 protecting the corner mirror body 12 is screwed to the outside of the corner mirror body 12. A fixing block 6 is screwed to the outside of the housing 8, and a rope chain 5 for moving the fixing block 6 is bolted to the top of the fixing block 6. A coiling rod 23 is screwed to the end of the rope chain 5 away from the fixing block 6, and a vertical frame 13 for rotating the coiling rod 23 is provided on the outside of the coiling rod 23. A drive rod 10 for rotating the coiling rod 23 is inserted into the outside of the vertical frame 13, and a threaded sleeve 14 for fixing the drive rod 10 is threaded to the outside of the drive rod 10. The top of the vertical frame 13 is screwed with a pulley 15 to stabilize the movement of the rope chain 5. The top of the vertical frame 13 is bolted with a box 2 for collecting rainwater. The outer side of the box 2 has a through hole 4 for rainwater to drain. A fixing plate 3 is slidably connected to the outside of the box 2. A rubber block 22 that blocks the through hole 4 is screwed on one side of the fixing plate 3. A spring 19 is welded to the end of the fixing plate 3 away from the rubber block 22. The top of the housing 8 is screwed with a connecting plate 11 that drives the fixing plate 3 to move. The surface of the connecting plate 11 has a fixing hole A17. The bottom of the connecting plate 11 and the top of the housing 8 both have fixing holes B18.

[0027] When adjusting the height of the corner mirror body 12, rotate the threaded sleeve 14 outside the drive rod 10 to separate the threaded sleeve 14 from the vertical frame 13. Then, drive the drive rod 10 to rotate, causing the winding rod 23 on one side of the drive rod 10 to wind up the rope chain 5. Then, the rope chain 5 drives the fixing block 6 to move through the pulley 15. The fixing block 6 drives the corner mirror body 12 inside the housing 8 to move. After the corner mirror body 12 is adjusted to a suitable height, rotate the threaded sleeve 14 outside the drive rod 10 to contact the vertical frame 13 and fix the drive rod 10, thus fixing the height of the corner mirror body 12. This makes it easy to adjust the height of the corner mirror body 12 as needed.

[0028] The box 2 at the top of the vertical frame 13 collects rainwater. When the corner mirror body 12 moves to the highest point, the connecting plate 11 on the outer shell 8 of the corner mirror body 12 drives the fixing plate 3 outside the box 2 to move. Then the fixing plate 3 presses the spring 19 on one side, and then the rubber block 22 outside the fixing plate 3 moves out from the through hole 4. The fixing hole A17 on the connecting plate 11 connects with the through hole 4 on the box 2. Then the water in the box 2 flows into the connecting plate 11 through the through hole 4 and the fixing hole A17. Then the fixing hole B18 at the bottom of the connecting plate 11 and the top of the shell 8 makes the water flow to the surface of the corner mirror body 12, which facilitates the washing of dust and foreign objects on the surface of the corner mirror body 12.

[0029] To filter rainwater entering housing 2, for example, such as Figure 1 As shown, the present invention also includes a filter frame 1 for filtering rainwater entering the box 2, which is fixed to the inside of the box 2 with screws.

[0030] When in use, when rainwater enters the box 2, the filter frame 1 inside the box 2 filters the rainwater entering the box 2. At the same time, the filter frame 1 inside the box 2 is disassembled and cleaned regularly to prevent the filter frame 1 from becoming clogged.

[0031] To prevent the rope chain 5 from shifting during winding, for example, as follows: Figure 2 As shown, the present invention also includes a support block 16 symmetrically sleeved on the outside of the coil rod 23 to limit the rope chain 5.

[0032] When in use, when the reel 23 winds up the rope chain 5, the support block 16 on the outside of the reel 23 limits the rope chain 5 to prevent it from shifting during winding.

[0033] To improve the stability of the movement of the corner mirror body 12, for example, such as Figure 1 As shown, the present invention also includes a sliding sleeve 7 symmetrically welded to the outside of the fixing block 6, and a sliding rod 9 slidably connected to the inside of the sliding sleeve 7.

[0034] When in use, when the fixing block 6 moves the corner mirror body 12 inside the housing 8, the sliding sleeve 7 outside the fixing block 6 slides outside the sliding rod 9, thereby improving the stability of the movement of the corner mirror body 12.

[0035] To improve the stability of the movement of the rubber block 22 driven by the fixed plate 3, for example, such as Figure 4 As shown, the present invention also includes a limiting groove 20 inside the housing 2, and a limiting block 21 connected to the fixing plate 3 is slidably connected to the inner side of the limiting groove 20.

[0036] When in use, when the fixing plate 3 moves the rubber block 22, the limiting block 21 outside the fixing plate 3 slides in the limiting groove 20 opened in the box 2, thereby improving the stability of the fixing plate 3 moving the rubber block 22.

[0037] When using this utility model, to adjust the height of the corner mirror body 12, rotate the threaded sleeve 14 outside the drive rod 10 to separate the threaded sleeve 14 from the vertical frame 13, and then drive the drive rod 10 to rotate, causing the winding rod 23 on one side of the drive rod 10 to drive the rope chain 5 to wind up. Then the rope chain 5 drives the fixing block 6 to move through the pulley 15, and the fixing block 6 drives the corner mirror body 12 inside the housing 8 to move. After the corner mirror body 12 is adjusted to a suitable height, rotate the threaded sleeve 14 outside the drive rod 10 to contact the vertical frame 13 and fix the drive rod 10, thereby fixing the height of the corner mirror body 12, which makes it easy to adjust the height of the corner mirror body 12 according to the needs.

[0038] The box 2 at the top of the vertical frame 13 collects rainwater. When the corner mirror body 12 moves to the highest point, the connecting plate 11 on the outer shell 8 of the corner mirror body 12 drives the fixing plate 3 outside the box 2 to move. Then the fixing plate 3 presses the spring 19 on one side, and then the rubber block 22 outside the fixing plate 3 moves out from the through hole 4. The fixing hole A17 on the connecting plate 11 connects with the through hole 4 on the box 2. Then the water in the box 2 flows into the connecting plate 11 through the through hole 4 and the fixing hole A17. Then the fixing hole B18 at the bottom of the connecting plate 11 and the top of the shell 8 makes the water flow to the surface of the corner mirror body 12, which facilitates the washing of dust and foreign objects on the surface of the corner mirror body 12.

[0039] When rainwater enters the interior of the housing 2, the filter frame 1 inside the housing 2 filters the rainwater entering the housing 2. At the same time, the filter frame 1 inside the housing 2 is disassembled and cleaned regularly to prevent the filter frame 1 from becoming clogged.

[0040] When the reel 23 winds up the rope chain 5, the support block 16 outside the reel 23 limits the rope chain 5 to prevent it from shifting during winding.

[0041] When the fixing block 6 moves the corner mirror body 12 inside the housing 8, the sliding sleeve 7 outside the fixing block 6 slides outside the sliding rod 9, thereby improving the stability of the movement of the corner mirror body 12.

[0042] When the fixed plate 3 moves the rubber block 22, the limiting block 21 outside the fixed plate 3 slides in the limiting groove 20 opened in the box 2, thereby improving the stability of the fixed plate 3 moving the rubber block 22.
