Abstract
The utility model relates to a self stabilized level rod, which comprises a body, a weight counterbalance device and a foot pin. The body is fixed on the weight counterbalance device which is provided with a conical body. A negative body matched with the conical body is arranged on the foot pin on which the weight counterbalance device is put through the conical body. The utility model has simple structure, easy production, and convenient use, and can keep stable and vertical without the supporting by hands of surveyors, thus solving the difficulty of manually keeping the level rod vertical and ensuring measuring precision, reducing the labor intensity of the surveyors and removing burden of manually keeping the level rod vertical.
Description
Technical field
The utility model relates to a kind of self-stabilization levelling pole, specifically, relates to a kind of homeostasis, does not need the hand steered levelling pole of survey crew.
Background technology
Existing levelling pole mainly contains following several: 1. measuring accuracy demanding four is to 3 meters used levelling poles of primary levelling; 2. the stretchable tower levelling pole of general measure accuracy requirement; 3. the hinged folding levelling pole of general measure accuracy requirement.All attach air level on these three kinds of levelling poles, water holding object staff person needs hand steered levelling pole, must guarantee that levelling pole does not rock all around when measuring, and also the very important person is placed in the middle for the air level on the control levelling pole, could guarantee that levelling pole is vertical.Yet, to measure in the operation, the hand-held levelling pole of staff is hurried back and forth in each measurement point, and itself is just very arduous, and also the very important person is difficult for really for the control levelling pole is vertical, and unavoidable levelling pole rocks.Therefore, be difficult to guarantee the precision of measurement.
The utility model content
The utility model provides a kind of self-stabilization levelling pole at the problems referred to above exactly, and it is hand steered that this levelling pole need not survey crew, can self keep stable with vertical.
The technical scheme that the utility model provides is: a kind of self-stabilization levelling pole, comprise blade, counter weight device and foot pin, blade is fixed on the counter weight device, and counter weight device is provided with cone-shaped body, have the recessed body that matches with cone-shaped body on the foot pin, counter weight device is seated on the foot pin by cone-shaped body.
Above-mentioned counter weight device is made up of balancing disk and equilibrate counterweight, and equilibrate counterweight is connected with balancing disk by connecting rod member.
Above-mentioned equilibrate counterweight is four, is connected with balancing disk by connecting rod member respectively.
Be provided with the jack that equilibrate counterweight connects rod member around bottom the above-mentioned blade, balancing disk is provided with corresponding jack, and equilibrate counterweight is by connecting in the jack of rod member on the jack insertion blade of balancing disk.Connection rod member by equilibrate counterweight is fixed on blade on the balancing disk.
The utlity model has following advantage and good effect: simple in structure, processing easily; Easy to use, need not survey crew hand steered, can self keep stable with vertical, solve vertical difficult of artificial control levelling pole and guaranteed measuring accuracy; Alleviate the working strength of survey crew, removed the vertical mental burden of artificial control levelling pole.

Fig. 2 is the vertical view of Fig. 1.
Embodiment
Referring to Fig. 1, Fig. 2, the utility model comprises blade 1, counter weight device and foot pin 8, and counter weight device is made up of balancing disk 2 and four equilibrate counterweights 3, and equilibrate counterweight 3 is connected on the balancing disk 2 by connecting rod member 4 symmetries respectively.Be provided with jack 5 around blade 1 bottom, balancing disk 2 is provided with corresponding jack 6; Also be provided with blade jack 7 on the balancing disk 2, it is interior also fixing by connecting rod member 4 that blade 1 inserts the blade jack 7 of balancing disk 2.Steadily balancing weight 3 is by connecting in the jack 5 of rod member 4 around balancing disk jack 6 inserts the blade bottom.The bottom of balancing disk 2 is a cone-shaped body, has the recessed body that matches with this cone-shaped body on the foot pin 8, and counter weight device and blade are seated on the foot pin 8 by cone-shaped body.
The utility model is seated in foot pin on the tested point, installs by said structure to make levelling pole exempt to hold up and vertical, until the measurement operation of finishing this point again.
