Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping tools, in particular to a surveying and mapping benchmark for building construction. Background Art

[0002] Construction surveying and mapping benchmarks are a tool used in the construction process to locate, measure and mark the position information of various parts of the required measurement site. By setting and using surveying and mapping benchmarks and combining them with advanced measuring instruments such as total stations and laser rangefinders, accurate measurement and recording can be achieved, which can ensure accuracy and precision in the construction process and improve construction efficiency and quality.

[0003] The existing patent (Announcement No.: CN209745293U) discloses a benchmark for construction surveying, including a pole body, a base fixedly connected to the bottom of the pole body, a vertical nail welded below the base, a level bubble installed in front of the base, a straightening device installed above the pole body, and the straightening device includes an outer shell, a partition and a fixing plate, the partition and the fixing plate are respectively fixedly connected to the upper and lower parts of the outer shell, a battery is installed above the partition, and a buzzer is installed above the outer shell. Start the switch before inserting the pole. If the pole body is tilted, when the plumb bob contacts the conductive copper sheet, the battery forms a conductor connected to the buzzer through the copper core vertical line, the plumb bob, the conductive copper sheet and the switch. The buzzer beeps to remind the surveyor that the pole is not in a horizontal position. If the plumb bob is in a vertical direction and does not contact the conductive copper sheet, the buzzer will not beep, and the pole is in a vertical position. It is easy to use and quick to straighten.

[0004] In this patent application, the surveying pole is fixed by holding the pole body and inserting the vertical nail into the soil on the ground.

The advantage is that the structure is simple and strong and the cost is low, but the disadvantage is that it occupies a large space and is not convenient for carrying and storing the surveying pole.

Based on the embodiments in 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.

[0039] Reference Figure 1-3 The utility model provides an embodiment: a construction surveying and mapping benchmark, including a base 1, a bottom sleeve 2 is fixedly connected to the middle of the base 1, a telescopic rod 3 is slidably connected to the middle of the bottom sleeve 2, a limit plate 4 is fixedly connected to the lower end of the bottom sleeve 2, a telescopic leg mechanism 5 is fixedly connected to the outer edge of the base 1, adjacent sides of the telescopic leg mechanism 5 are connected to the middle limit mechanism 6, the middle of the middle limit mechanism 6 is slidably connected to the outer surface of the bottom sleeve 2, a horizontal instrument mechanism 7 is fixedly connected to the front upper surface of the bottom sleeve 2, an electric power mechanism 8 is fixedly connected to the rear upper surface of the horizontal instrument mechanism 7, an indicating mechanism 9 is fixedly connected to the top and outer edge of the telescopic rod 3, and when the device is used, the telescopic leg mechanism 5 is fixedly connected to the outer edge of the base 1. The telescopic leg mechanism 5 can form support for the base 1 and the bottom sleeve 2 when the telescopic leg mechanism 5 is unfolded. At the same time, the telescopic leg mechanism 5 is limited by the cooperation of the middle limiting mechanism 6 and the limiting plate 4, and the unfolding angle of the telescopic leg mechanism 5 is limited. The telescopic rod 3 can make the rod body of the device telescopic and folded into the interior of the bottom sleeve 2. When the telescopic leg mechanism 5 is unfolded, the horizontal plane of the device can be detected by the horizontal instrument mechanism 7 on the base 1, and the device can be adjusted through the telescopic leg mechanism 5. In the case of poor visibility, the power mechanism 8 is started to supply power to the indicating mechanism 9, and the illuminated indicating mechanism 9 is used to indicate the position of the device to the surveying and mapping device, thereby expanding the scope of application of the device.

[0040] The telescopic leg mechanism 5 includes an articulated frame 501 and a connecting shaft 502. The adjacent sides of the articulated frame 501 are fixedly connected to the outer edge of the base 1. The middle part of the articulated frame 501 is fixedly connected to both ends of the connecting shaft 502. The middle outer surface of the connecting shaft 502 is rotatably connected with an articulated seat 503. The lower end of the articulated seat 503 is fixedly connected with a bracket sleeve 504. The inner surface of the bracket sleeve 504 is slidably connected with a sliding support rod 505. The lower end outer surface of the bracket sleeve 504 is threadedly connected with a fixed sleeve 506. The adjacent sides of the bracket sleeve 504 are fixedly connected to the outer side of the middle limiting mechanism 6. The connection allows the bracket sleeve 504 connected to the hinge seat 503 to rotate around the connecting shaft 502, thereby achieving the purpose of adjusting the expansion angle of the bracket sleeve 504 and the sliding support rod 505. Through the sliding connection between the bracket sleeve 504 and the sliding support rod 505, the sliding support rod 505 can be adjusted along the sliding support rod 505, and after the sliding support rod 505 is adjusted to a suitable length, the extended length of the sliding support rod 505 can be fixed by tightening the fixing sleeve 506 (this is the prior art). Through the connection between the bracket sleeve 504 and the middle limiting mechanism 6, the expansion angle of the bracket sleeve 504 is limited, so that the device can be stably supported in the measuring position.

[0041] The middle limiting mechanism 6 includes a fixed plate 601 and a sliding sleeve 604. The far sides of the fixed plate 601 are fixedly connected to the middle adjacent sides of the bracket sleeve 504. The left and right sides of the fixed plate 601 are rotatably connected to the connecting rod 602. The proximal ends of the connecting rod 602 are rotatably connected to the connecting plate 603. The adjacent sides of the connecting plate 603 are fixed to the outer side of the sliding sleeve 604. The inner surface of the middle part of the sliding sleeve 604 is slidably connected to the outer surface of the bottom sleeve 2. Through the connection between the fixed plate 601, the connecting rod 602 and the connecting plate 603, When the bracket sleeve 504 is unfolded, it can synchronously drive the connecting plate 603 and the sliding sleeve 604 to move forward through the fixed plate 601 and the connecting rod 602, and the unfolding angle of the bracket sleeve 504 is limited by the cooperation between the sliding sleeve 604 and the limit plate 4. When the telescopic leg mechanism 5 needs to be folded, the connecting plate 603 and the sliding sleeve 604 are pushed upward by squeezing the bracket sleeve 504, so that the bracket sleeve 504 is folded up, and the contraction of the telescopic rod 3 and the sliding support rod 505 is coordinated to achieve the purpose of reducing the space occupied by the device.

[0042] The leveling instrument mechanism 7 includes a fixed seat 701 and a universal bubble level 702. The lower surface of the fixed seat 701 is fixedly connected to the front upper surface of the base 1, and the lower surface of the universal bubble level 702 is fixedly connected to the middle upper surface of the fixed seat 701. The universal bubble level 702 can be firmly fixed on the base 1 through the fixed seat 701, and the horizontal and vertical angles between the base 1 and the telescopic rod 3 can be detected through the universal bubble level 702. The device can be adjusted by adjusting the length of the sliding support rod 505 according to the information provided by the universal bubble level 702, so that the surveyor can align with the target point more accurately and reduce errors and deviations.

[0043] The power mechanism 8 includes a power switch 801 and a battery 802. The lower surface of the power switch 801 is fixedly connected to the left upper surface of the base 1, and the lower surface of the battery 802 is fixedly connected to the rear upper surface of the base 1. The power switch 801 is electrically connected to the battery 802. The output of the battery 802 can be controlled by the power switch 801 fixed on the base 1. When the battery 802 needs to be used to power the indicating mechanism 9 under poor visibility conditions, the power switch 801 is turned on to power it. When the indicating mechanism 9 is not needed, the power switch 801 can be turned off to disconnect the connection between the indicating mechanism 9 and the battery 802.

[0044] The indicating mechanism 9 includes a top indicator light 901 and an indicator light strip 902. The lower end of the top indicator light 901 is fixedly connected to the top of the telescopic rod 3. The inner surface of the indicator light strip 902 is fixedly connected to the outer surface of the telescopic rod 3. The top indicator light 901 and the indicator light strip 902 are electrically connected to the power switch 801. The top indicator light 901 and the indicator light strip 902 arranged on the telescopic rod 3 can provide assistance to the surveying and mapping equipment through the power supply of the power mechanism 8 when visibility is not high. The top indicator light 901 arranged at the upper end of the telescopic rod 3 can provide the surveying and mapping equipment with the height data of the telescopic rod 3. The indicator light strip 902 arranged on the outer edge of the telescopic rod 3 can provide auxiliary information to the surveying and mapping device.

[0045] A lighting lamp 10 is fixedly connected to the left upper surface of the fixing base 701, and the lighting lamp 10 is electrically connected to the power switch 801. By being arranged on the fixing base 701, the lighting lamp 10 can provide lighting for the universal bubble level 702 through the power supply of the power mechanism 8 when visibility is low, so that the user can check the universal bubble level 702 to adjust the device.

[0046] The lower end of the sliding support rod 505 is fixedly connected with an anti-skid rubber sleeve 11. The anti-skid rubber sleeve 11 set at the lower end of the sliding support rod 505 can increase the friction between the contact surface of the device and the ground, strengthen the supporting effect of the sliding support rod 505, and make the device more stable during use.

[0047] Working principle: When using the device, first move the device to the use point. The telescopic leg mechanism 5 arranged on the outer edge of the base 1 can support the base 1 and the bottom sleeve 2 when the telescopic leg mechanism 5 is unfolded. The extension length of the sliding support rod 505 can be fixed by tightening the fixing sleeve 506. The anti-slip rubber sleeve 11 arranged at the lower end of the sliding support rod 505 can increase the friction between the contact surface of the device and the ground, thereby strengthening the supporting effect of the sliding support rod 505. At the same time, the telescopic leg mechanism 5 is limited by the cooperation of the middle limit mechanism 6 and the limit plate 4. The telescopic rod 3 enables the rod body of the device to be telescopically folded into the bottom sleeve 2, and the cooperation between the sliding sleeve 604 and the limit plate 4 limits the deployment angle of the bracket sleeve 504, thereby limiting the deployment angle of the telescopic leg mechanism 5. When the telescopic leg mechanism 5 needs to be folded, the bracket sleeve 504 is squeezed to push the connecting plate 603 and the sliding sleeve 604 upward, thereby folding the bracket sleeve 504, and the contraction of the telescopic rod 3 and the sliding support rod 505 is coordinated to achieve the purpose of reducing the space occupied by the device;

[0048] The horizontal plane of the device can be detected by the level instrument mechanism 7 on the base 1, so that the surveyor can align the target point more accurately and reduce errors and deviations. The lighting lamp 10 arranged on the fixed base 701 can provide lighting for the universal bubble level 702 when visibility is not high. When visibility is poor, the indicating mechanism 9 is activated by the power mechanism 8 to indicate the position of the device to the surveying and mapping device, thereby providing assistance to the surveying and mapping equipment and expanding the scope of application of the device.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
