Technical Field
[0001] The utility model relates to the technical field of concrete detection equipment, in particular to a concrete perspective instrument. Background Art
[0002] Concrete perspective instruments are used in dry concrete structures to determine the location of steel bars, metal and plastic pipes, fiberglass cables, voids and wood, up to a depth of 300mm, to reduce the risk of hitting hidden objects when drilling holes or through holes, blasting openings and in diamond coring and cutting work, to extend steel bars in structural applications (post-laying steel bar connections), to inspect structures such as tunnels, bridges and floors, decks, slabs, balconies, etc. of buildings to detect voids and cavities in concrete structures. However, existing concrete perspective instruments have the following disadvantages:
[0003] 1. When using the concrete perspective instrument, the inspector holds the handle to fit the concrete perspective instrument to the surface of the concrete, and then moves the concrete perspective instrument through the rollers on the back of the concrete perspective instrument to perform the inspection. However, when inspecting vertical concrete walls, hand-held movement cannot ensure that the concrete perspective instrument is completely horizontal, and the moving route may be offset. Secondly, it is laborious to hold the concrete perspective instrument for a long time to move and inspect.
[0004] 2. When the concrete perspective instrument is in use, the rubber sleeve on the roller surface is in contact with the concrete surface all the time, which will cause wear. When the wear is serious, it is inconvenient to replace the rubber sleeve of the existing concrete perspective instrument. Utility Model Content

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] like Figure 1-Figure 4 As shown, it relates to a concrete perspective instrument, including a perspective instrument body 1, a display screen 2 is provided at the bottom end of the front side of the perspective instrument body 1, a handle 3 is fixed to the middle part of the front side of the perspective instrument body 1, grooves 4 are provided on both sides of the back side of the perspective instrument body 1 away from the display screen 2, a roller assembly 5 is provided inside the groove 4, screw holes 6 are provided at the top and bottom ends of the groove 4, a mounting assembly 7 for fixing the roller assembly 5 is provided inside the screw hole 6, a telescopic assembly 8 is fixedly connected to the bottom end of the perspective instrument body 1, a plurality of support rods 9 are connected to the bottom end of the telescopic assembly 8, and a universal wheel 10 is fixedly connected to the bottom end of the lowest support rod 9.
[0025] like Figure 1 As shown, a sponge sleeve is sleeved on the surface of the handle 3.
[0026] The sponge cover can make the user hold the handle 3 more comfortable.
[0027] like Figure 1-Figure 4 As shown, the roller assembly 5 includes a wheel body 51 located inside the groove 4 , and shaft holes 52 are formed at both ends of the wheel body 51 . A detachable rubber sleeve 53 is sleeved on the surface of the wheel body 51 .
[0028] The rubber sleeve 53 can prevent the wheel body 51 from directly contacting the concrete, thereby protecting the wheel body 51 .
[0029] like Figure 4 As shown, an annular groove 54 for clamping the rubber sleeve 53 is formed on the surface of the wheel body 51 .
[0030] The rubber sleeve 53 can be directly slidably sleeved on the surface of the wheel body 51. The length of the annular groove 54 is the same as the length of the rubber sleeve 53. The thickness of the annular groove 54 is less than 1 mm, so that after the rubber sleeve 53 is sleeved on the surface of the wheel body 51, the wheel body 51 does not contact the concrete surface.
[0031] like Figure 3 and Figure 4 As shown, the mounting assembly 7 includes a connecting shaft 71, one end of which is fixedly connected to an end cap 72, an external thread is provided on the surface of the connecting shaft 71 close to the end cap 72, and the threaded end of the connecting shaft 71 is rotatably connected to the screw hole 6, the end of the connecting shaft 71 that passes through the screw hole 6 and is located in the groove 4 is inserted into the shaft hole 52 of the wheel body 51, and the connecting shaft 71 is rotatably connected to the shaft hole 52.
[0032] After screwing the connecting shaft 71 into the screw hole 6, the smooth part of the connecting shaft 71 can be inserted into the shaft holes 52 at both ends of the wheel body 51, and the wheel body 51 can be rotated inside the groove 4 through the connecting shaft 71. When the wheel body 51 needs to be disassembled, the end cap 72 is rotated to make the connecting shaft 71 withdraw from the shaft hole 52, and the wheel body 51 can be taken out from the groove 4.
[0033] like Figure 1-Figure 2 As shown, the telescopic assembly 8 includes a fixing rod 81 fixed to the bottom of the fluoroscopy body 1, a round tube 82 is slidably connected to the bottom surface of the fixing rod 81, and a locking bolt 83 is penetrated through the side wall of the top end of the round tube 82 and is threadedly connected.
[0034] The support rod 9 plays a supporting role at the bottom of the telescopic assembly 8. When the height of the perspective instrument body 1 needs to be fine-tuned, the round tube 82 can be slid up and down to change the overall length of the round tube 82 and the fixed rod 81. After the adjustment is completed, the locking bolt 83 can be tightened.

[0036] Before use, according to the height of the concrete wall to be measured, the appropriate number of support rods 9 can be rotated, and then the support rods 9 can be screwed to the bottom of the round tube 82 for fixing, and finally the universal wheel 10 can be screwed to the bottom of the support rods 9.
[0037] Working principle: Before use, first confirm the height of the concrete wall to be measured, then take out the corresponding number of support rods 9, first take a support rod 9, screw the screw 11 at one end of it into the thread groove 12 at the bottom of the round tube 82, then screw the screw 11 of the next support rod 9 into the thread groove 12 at the bottom of the support rod 9, thereby realizing the splicing of multiple support rods 9. After the support rods 9 are spliced, screw the screw 11 at the top of the universal wheel 10 into the thread groove 12 at the bottom of the lowest support rod 9, then adjust the round tube 82 to slide on the surface of the fixed rod 81, fine-tune the height of the perspective instrument body 1, and finally tighten the locking bolt 83. During the inspection, start the perspective instrument body 1 and then hold the handle 3 to move the perspective instrument body 1. At this time, the support rods 9 and the universal wheels 10 play a supporting role, and the roller assembly 5 fits the roller with the concrete wall. When the rubber sleeve 53 on the surface of the wheel body 51 needs to be replaced, first screw the connecting shafts 71 at both ends of the groove 4 out of the screw holes 6. After the connecting shafts 71 are withdrawn from the shaft holes 52 at both ends of the wheel body 51, the wheel body 51 can be taken out of the groove 4, then the rubber sleeve 53 on the surface of the wheel body 51 is removed and a new rubber sleeve 53 is put on. Finally, the wheel body 51 is placed in the groove 4, and the connecting shaft 71 is screwed back into the shaft holes 52 at both ends of the wheel body 51.
