Description

Easy-to-adjust bracket structure for the tower ruler

technical field

The utility model relates to the field of measuring auxiliary tools, in particular to a support structure for a conveniently adjustable tower ruler.

Background technique

In electric power construction operations, measuring instruments such as theodolites or levels are often used to measure various types of numerical measurements on the construction work surface. Every time a measurement is carried out, a special person is required to support the tower ruler, which is labor-intensive.

At the same time, when the ruler is manually held up, people are used as supports, and the slight shaking of the person holding the ruler will affect the alignment operation of the crosshairs, and repeated alignment readings increase the measurement time.

If the staff of the ruler cannot place the tower ruler completely vertically on the ground during the measurement, it will cause a large error in the reading or an error in the reading. The wrong value will leave a safety hazard for the follow-up work, and the measurement will be repeated again, resulting in low work efficiency.

And although the tower ruler support in the prior art adopts a telescopic structure, because the tower ruler support is used to install the tower ruler, when the tower ruler is read, the accuracy of the horizontal degree is required to be higher, and the existing telescopic structure must not be adjusted. The accuracy is not high, or the instability is insufficient, and it cannot meet the needs of tower ruler adjustment.

Utility model content

The technical problem to be solved by the utility model is: the telescopic structure in the prior art is either not high in adjustment accuracy, or insufficient in stability, and cannot meet the needs of tower ruler adjustment. The purpose is to provide a higher adjustment accuracy, stable It is more convenient to adjust the bracket structure for the tower ruler.

The utility model is realized through the following technical solutions:

The bracket structure for the adjustable tower ruler includes a tower ruler connecting sleeve with a tower ruler mounting hole, and a bracket rod connected to the tower ruler connecting sleeve; the bracket rod includes an outer rod, and one end extends into the outer rod and is connected to the The inner rod connected with the outer rod, and the backstop structure arranged inside the inner rod;

The backstop structure includes a backstop rod penetrating the inner rod, a backstop seat arranged at the end of the inner rod extending into the outer rod, and a backstop seat arranged at one end of the backstop rod and engaged with the backstop seat. Column, a connecting seat that is sleeved on the other end of the stop rod and fixedly connected with the connecting sleeve of the tower ruler, a stop cap that is fixedly arranged on the other end of the stop rod and cooperates with the connecting seat to prevent mutual rotation, and a socket Coil spring on backstop rod between backstop cap and connection seat.

In the utility model, through the cooperation of the outer rod, the inner rod and the screw sleeve, the relative rotation of the inner rod and the outer rod can be realized, and the adjustment of the overall length of the inner rod and the outer rod can be realized after the relative rotation of the inner rod and the outer rod . Due to the thread method, the overall length of the inner rod and the outer rod can be adjusted every time a certain number of turns of the thread are rotated. By controlling the distance between two adjacent threads, the inner rod can be realized after the thread rotates one circle. And the control of the length of the overall increase of the outer rod, and when rotating, the number of turns that can be rotated is not an integer, so that the adjustment of the overall length of the inner rod and the outer rod is more accurate.

However, when adjusting the overall length of the inner rod and the outer rod, it is easy to accidentally touch the part of the rotation adjustment during the operation, resulting in low stability of the adjustment and thus affecting the accuracy of the adjustment.

Moreover, this structure is more convenient for the operator to adjust the height, and the operation is more convenient.

In order to better adjust the tightness of the coil spring so that the anti-retraction column is better snapped onto the anti-retraction seat, the anti-retraction column is provided with a through hole, and the end of the anti-retraction rod connected to one end of the anti-retraction column is provided with a external thread, the backstop post is fixed on the backstop rod through a hexagon head nut connected to the outer thread of the backstop rod.

In order to better fix the support rod on the ground and increase the service life, the end of the outer rod far away from the end of the inner rod is also provided with a fixing seat, and a protective cover is also arranged on the fixing seat.

Preferably, the number of the support rods is set to three, which are evenly distributed around the outer wall of the connecting sleeve of the tower ruler, and the connecting seats on the support rods are fixed on the connecting sleeve of the tower ruler through hinges.

The utility model can effectively form the most stable triangular structure through the arrangement of three support rods, thereby increasing the stability of the utility model, and the structure of the three telescopic rods can also more effectively adjust the tower feet in different directions The height between the connecting sleeve and the ground satisfies different terrain requirements, and thus can be applied to any complex terrain conditions, and the scope of application is wider.

As a preferred implementation, the hinge includes two connecting pieces fixed on the connecting sleeve of the tower ruler, a through hole arranged on the connecting piece, and a hinge piece hinged on the through hole through a connecting rod at one end, fixed on the hinge The other end of the sheet is used for a connecting head connected to the top of the bracket rod; the hinged sheet is located between the two connecting sheets and is parallel to the two connecting sheets; the connecting head is fixedly connected to the connecting seat.

Further, the central axis of the tower ruler installation hole is set perpendicular to the connecting rod.

Preferably, the connecting sleeve of the tower ruler is made of stainless steel, and the outer rod and the inner rod are both made of aluminum tubes.

Through the optimized setting of the above structure, it can not only effectively achieve the purpose of stable reading, improve the accuracy and speed of tower foot reading, but also effectively apply to the use of different terrains, and has the advantages of light weight and convenient retraction. It is very convenient to carry, has a long service life and low cost, and is very suitable for promotional applications.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

1. Through the optimized setting of the screw sleeve and the backstop structure, the utility model can effectively prevent the problem of low stability while realizing precise adjustment of the length, and then achieve the purpose of higher adjustment accuracy and better stability;

2. The utility model can adjust the height between the connecting sleeve of the tower ruler and the ground in different directions to meet different terrain requirements, and can be applied to any complex terrain conditions, and the scope of application is wider.
