Description

multifunctional centering rod

technical field

The utility model relates to a measuring device, in particular to a centering rod.

Background technique

The general structure of surveying and mapping equipment used in current field survey work is that a prism is placed on the upper end of the centering rod, and the lower end of the centering rod is placed on the object to be measured. The use of this type of equipment generally requires the cooperation of 3 people, one person observes the instrument, one person gradually runs the prism to observe according to the terrain of the survey area, and one person follows the runner to draw a sketch. The disadvantage is that it requires more manpower.

Specifically, the existing centering rod structure includes a rod body and a slot at the top of the rod body, wherein the height of the rod body can be adjusted up and down, and the slot is used to place a prism. Neither the prism, the centering pole, the tripod, nor a combination of the three has room for a slate. If you want to reduce the number of workers to reduce labor costs, two people will complete the survey, and generally require the observer to draw a sketch at the same time. But using existing equipment is difficult to achieve. Therefore, when there are only two people, the runners can only free up their hands to draw a sketch with the recording board after observing the data of each measuring point, which reduces the speed of measurement and affects work efficiency.

Therefore, those skilled in the art are devoting themselves to developing a multifunctional centering rod to overcome the above-mentioned defects.

Utility model content

As shown in FIG. 1 , the utility model provides a multifunctional centering rod, which includes a rod body 1 and a connecting device 2 . The connecting device 2 includes a placing plate 21 and a clamping member 22 , wherein the placing plate 21 is connected to the clamping member 22 , and the clamping member 22 is connected to the rod body 1 . The placing board 21 can be kept relatively fixed with the rod body 1 through the clamping member 22, and is used for placing a recording board, so that the observer can record while observing.

According to a preferred embodiment of the present utility model, the connection between the placement plate 21 and the clamping member 22 is a detachable connection, as shown in FIG. A socket 2201 matching the pin 211. When in use, the plug 211 can be inserted into the socket 2201; when not in use, it can be removed without affecting each other, which is convenient for carrying and transportation.

It is worth reminding that the cross-sections of the pin 211 and the insertion hole 2201 are preferably made non-circular, so that the placing plate 21 and the clamping member 22 are not easy to shake relative to each other.

As an alternative embodiment, as shown in FIG. 3 , the clamping member 22 ′ is provided with a horizontal insertion hole 2201 ′ matching the placement plate 21 ′. When in use, the placement plate 21' is directly inserted into the horizontal jack 2201'; when not in use, it can be removed without affecting each other, which is convenient for carrying and transportation.

In other embodiments, the connection between the placing plate 21 and the clamping member 22 can also be a fixed connection or a rotatable connection, and basically the same technical effect can also be obtained.

When the connection between the placing plate 21 and the holding member 22 is rotatable, the placing plate 21 is connected to the holding member 22 through a rotating shaft. When not in use, the placing board 21 and the clamping member 22 can be folded and placed, which is convenient for carrying and transportation; when in use, they only need to be unfolded, and the operation is simple and convenient.

According to a preferred embodiment of the present invention, the connection between the clamping part 22 and the rod body 1 is a detachable connection. As shown in FIG. 4 , the clamping part 22 is provided with two clamping pliers 221 . When in use, use the two clamping pliers 221 to clamp the rod body 1, so that the clamping part 22 and the rod body 1 remain relatively fixed;

In order to better fix the clip 22 on the rod body 1 , the connecting device 2 further includes a fastener 23 . The fastener 23 , specifically one of detachable screw nut, screw or pin, is mounted on the outer ends of the two clamping pliers 221 . In use, only need to tighten the fastener 23 so that the two clamping pliers 221 clamp each other, the clamping member 22 can be kept fixed relative to the rod body 1 .

As an alternative embodiment, in order to better fix the clip 22 on the rod body 1, the connecting device 2 further includes a fastening pin 24; the rod body 1 is provided with a through hole matching the fastening pin 24 101 ; the two clamping pliers 221 are respectively provided with a through hole 2202 corresponding to the through hole 101 and matched with the fastening pin 24 . When the clamping member 22 is connected with the rod body 1 , the fastening pin 24 can pass through the through hole 101 and the two through holes 2202 to keep the clamping member 22 fixed relative to the rod body 1 . In other embodiments, basically the same technical effect can also be obtained by using more than one through hole 101 .

In this embodiment, the clamping member 22 can move up and down along the rod body 1 to adjust the height of the placement plate 21 to meet the needs of observers of different heights, which is beneficial for observers to record.

It is worth reminding that when the clamping member 22 only uses the two clamping pliers 221 to clamp the rod body 1 , a mutual pulling force should be generated between the two clamping pliers 221 . For example, a spring is installed inside the two clamping pliers 221, or a spring is installed on the connecting shaft of the two clamping clamps 221; when the two clamping clamps 221 were fastened by other elements, the two There is no need to generate a mutual pulling force between the clamping jaws 221 , of course such a mutual pulling force is also possible.

In other embodiments, the connection between the clamping member 21 and the rod body 1 can also be a fixed connection, and basically the same technical effect can also be obtained.

When the connection between the clamping part 21 and the rod body 1 is a fixed connection, in order to facilitate the carrying and transportation of the multifunctional centering rod, the connection between the placement plate 21 and the clamping part 22 can be rotatable. . When not in use, turn the placing plate 21 to stick to the rod 1; when in use, unfold the placing plate 21, the operation is simple and convenient.

It is worth reminding that several connection modes between the placing plate 21 and the clamping part 22 and several connection modes between the clamping part 22 and the rod body 1 can be cross-implemented. That is, no matter what kind of connection between the placement plate 21 and the clamping part 22 does not affect the connection between the clamping part 22 and the rod body 1; 1 does not affect the connection between the placement plate 21 and the clamping member 22.

The connecting device 2 also includes a fixing member 25 arranged on the placing board 21 for fixing the recording board so as to keep it relatively fixed.

The fixing part 25 is composed of two groups of detachable nuts and screws, and the screws in each group pass through the placement plate and are fixed by the corresponding nuts in the group. In use, the recording board is sandwiched between the two removable screw nuts.

As an alternative embodiment, the fixing member 25 can also be a clip arranged on the placement board 21 , and the fixing member 25 clamps the recording board on the placement board 21 during use.

It is worth reminding that since some recording boards themselves have elements for fixing, the fixing member 25 is not an essential element.

The multifunctional centering rod also includes a circular level 3 . The circular level 3 is installed on the rod body 1 to test the levelness, so that the multifunctional centering rod has the function of testing the levelness, and there is no need to carry other instruments for testing the level during measurement, which is convenient to the surveyor.
