Background
The centering rod for surveying and mapping is used as an indispensable centering device in surveying and mapping, has wide application in surveying and mapping, and is a metal rod capable of directly pointing to a ground mark point in the vertical direction. When the centering rod is generally used, a support is needed to assist the centering rod in supporting. The bottommost ends of supporting legs of the conventional centering rod support are pointed, and the triangular structure formed by the support and the centering rod is very stable and is very suitable for places such as construction sites, roads and the like. However, the use of the floor covering is limited to smooth floors or slippery and extremely uneven stones, and is not only easy to slip, but also easy to wear the floor, or inconvenient due to insufficient stability.
The prior art CN104142146A provides a centering rod support, wherein a sleeve capable of moving along the axial direction of the outer tube is sleeved on the outer surface of the outer tube, and a claw-shaped part is arranged at the tail end of the sleeve, so that when the centering rod support is used on a smooth floor, the sleeve can be put down and locked by a fastener, the claw-shaped part is used for landing, the stressed area is increased, and the stability is improved; the claw tips of the claw-shaped parts are arranged in a bent structure, so that the abrasion of the claw tips to the floor is prevented. However, since the first support bar and the second support bar are used in an inclined manner, when the claw portion is used to land, the tip of the claw portion is bent, and the first support bar and the second support bar are unstable.
Therefore, the problem that the technical personnel in the field need to solve is to provide a quick centering bracket for mapping to overcome the slipping phenomenon when the bracket is used on a smooth surface and improve the stability of the bracket.
Disclosure of Invention
The invention is based on at least one of the technical problems, and provides a quick centering bracket for mapping, which can overcome the slipping phenomenon when used on a smooth surface and improve the stability of the bracket; meanwhile, the application range of the centering bracket is enlarged.
In view of the above, the invention provides a quick centering bracket for surveying and mapping, which comprises two support rods and a centering rod; the support rods are respectively a first support rod and a second support rod; the device is characterized by also comprising fixed support legs which are respectively arranged on the first support rod and the second support rod; the fixed support legs are fixed on the first support rod and the second support rod through the triangular support frame;
the fixed support legs comprise pressure bars, supporting platforms, springs, support rods and buffer support platforms; wherein the supporting platform is fixed on the triangular supporting frame; a pressure lever is arranged above the supporting platform; the spring is arranged between the supporting platform and the buffering support; the supporting rod is sleeved inside the spring, one end of the supporting rod is connected with the buffering supporting platform, and the other end of the supporting rod penetrates through the supporting platform and is movably connected with the pressing rod.
Preferably, the weight of the plunger is substantially greater than the spring tension.
Preferably, the first support bar and the second support bar are retractable support bars.
The first support rod and the second support rod support the centering rod through the connecting assembly; the tail ends of the first supporting rod and the second supporting rod are respectively provided with a first pointed head part and a second pointed head part which are used for landing.
Furthermore, the supporting rod is movably connected with the pressing rod through a pin; the pressure lever is provided with a pin hole matched with the pin.
Preferably, the plunger is movable about the pin.
According to the invention, through the arrangement of the fixed support legs, when the fixed support legs are required to be utilized, the pressing rod is pulled downwards and can move around the pin, and the weight of the pressing rod is far greater than the stretching force of the spring; the press rod is heavy, and the support rod connected with the pin moves downwards; thereby causing the springs connected between the support platform and the cushion support to stretch; the buffer support platform below the support rod descends along with the support rod, and the contact ground is flush with the first pointed end at the tail end of the first support rod; when the supporting is not needed to be supported through the fixed supporting legs, the pressing rod only needs to be pulled upwards, the pressing rod can move around the pin, and the supporting rod can be restored to the original state.
Through the technical scheme, the invention provides the quick surveying and mapping centering bracket, which can overcome the slipping phenomenon when the bracket is used on a smooth surface and improve the stability of the bracket; meanwhile, the application range of the centering bracket is enlarged.
