Description

Technical Field

[0001] The utility model is applicable to the technical field of engineering measurement, and particularly relates to an auxiliary device for engineering measurement. Background Art

[0002] At present, during engineering surveying operations, the task of drawing engineering drawings still needs to be drawn manually. Therefore, when a project requires manual drawing, engineers need to use drawing tools on a drawing board to draw engineering drawings. The most commonly used drawing tool is a drawing ruler, which is convenient for measuring drawing dimensions.

[0003] However, the current measuring rulers for engineering drawings are often made of a single ruler-shaped plastic plate, and such measuring rulers have a limited measuring range and cannot be adjusted for applicability, which results in poor usability for large-scale engineering building drawings, affecting the drawing quality and causing unnecessary delays in the drawing speed. Therefore, we propose an auxiliary device for engineering measurement. Utility Model Content

[0004] The main purpose of the utility model is to provide an auxiliary device for engineering measurement, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An auxiliary device for engineering measurement, comprising a storage frame, wherein a first scale plate and a second scale plate are respectively slidably inserted on two sides of the storage frame;

[0007] The top side surfaces of the first scale plate and the second scale plate are both fixedly mounted with transmission racks, the top middle end of the storage frame is vertically rotatably mounted with a rotating rod through a bearing, the bottom surface of the rotating rod is fixedly sleeved with a transmission gear, and the outer side of the transmission gear is meshed with the side of the transmission rack;

[0008] The transmission gear and the transmission rack are both movably installed inside the storage frame.

[0009] By adopting the above technical solution, through the meshing transmission action of the transmission gear and the transmission rack, and the first scale plate and the second scale plate are arranged on both sides of the storage frame, the first scale plate and the second scale plate can be driven to move out from both sides of the storage frame synchronously towards or relative to each other. Combined with the scale lines arranged on the surfaces of the storage frame and the two groups of scale plates, the measurement range of the overall mechanism can be increased and the labor consumption required for the operator to repeat measurements can be reduced.

[0010] As an optional solution to the technical solution of the present application, both ends of the side of the storage frame are screwed with tightening bolts through threads, and each side of the tightening bolt is fixedly bonded with an anti-slip friction pad, and the side of the anti-slip friction pad is movably fitted to the outer surfaces of the first scale plate and the second scale plate.

[0011] By adopting the above technical solution, the use stability of the first scale plate and the second scale plate can be ensured through the structural effect of the tightening bolts and the anti-slip friction pad.

[0012] As an optional solution of the technical solution of the present application, sliding blocks are fixedly installed on the surfaces of both ends of the side edges of the first scale plate and the second scale plate, and the sliding blocks are slidably installed inside the storage frame. Sliding grooves are opened on both sides of the storage frame, and the sliding blocks are slidably inserted into the sliding grooves.

[0013] By adopting the above technical solution, the movement stability of the two groups of scale plates is ensured by the guiding sliding action of the sliding groove on the sliding block.

[0014] As an optional solution of the technical solution of the present application, a hand-pushed turntable is fixedly sleeved on the top surface of the rotating rod, and the hand-pushed turntable is rotated and located outside the storage frame.

[0015] By adopting the above technical solution, the operator can conveniently adjust the positions of the two sets of scale plates through the structural function of the hand-pushed turntable.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application is an auxiliary device for engineering measurement, in which a first scale plate and a second scale plate are slidably inserted on both sides of a storage frame, and the meshing transmission action of a transmission gear and a transmission rack is combined, so that after the rotating rod is pushed to drive the transmission gear to rotate synchronously inside the storage frame, a corresponding driving force can be provided to the two sets of transmission racks, thereby driving the first scale plate and the second scale plate to move synchronously toward or relative to each other from both sides of the storage frame. Combined with the scale lines provided on the surfaces of the storage frame and the two sets of scale plates, the measurement range of the overall mechanism can be increased, and the labor consumption required for the operator to perform repeated measurements can be reduced.

[0018] 2. The technical solution of the present application is an auxiliary device for engineering measurement, which slides the sliding block into the sliding groove, and combines the guiding sliding action of the sliding groove on the sliding block, so that the first scale plate and the second scale plate can only move horizontally inside the storage frame after being driven without lateral movement, thereby ensuring the measurement accuracy of the overall measuring ruler.

[0023] like Figure 1-3 As shown, the utility model provides a technical solution: an auxiliary device for engineering measurement, both ends of the side of the storage frame 1 are screwed with tightening bolts 3 through threads, and each tightening bolt 3 is fixedly bonded with an anti-skid friction pad 5 on the side, and the side of the anti-skid friction pad 5 is movably fitted to the outer surface of the first scale plate 11 and the second scale plate 12.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), the first scale plate 11 and the second scale plate 12 are slidably inserted on both sides of the storage frame 1, and a hand-pushed turntable 22 is fixedly sleeved on the top surface of the rotating rod 21, and the hand-pushed turntable 22 is rotated to the outside of the storage frame 1.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), the transmission rack 2 is fixedly installed on the top side surfaces of the first scale plate 11 and the second scale plate 12, and a rotating rod 21 is vertically rotatably installed on the top middle end of the storage frame 1 through a bearing, and a transmission gear 23 is fixedly sleeved on the bottom surface of the rotating rod 21, and the outer side of the transmission gear 23 is meshed with the side of the transmission rack 2, and the transmission gear 23 and the transmission rack 2 are movably installed inside the storage frame 1.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), sliding blocks 41 are fixedly installed on the surfaces of both ends of the side edges of the first scale plate 11 and the second scale plate 12, and the sliding blocks 41 are slidably installed inside the storage frame 1, and sliding grooves 4 are opened on both sides of the storage frame 1, and the sliding blocks 41 are slidably inserted into the sliding grooves 4.

[0027] During operation, when it is necessary to measure and draw the architectural design drawing on the drawing board surface, the tightening bolt 3 is reversely screwed to drive the anti-skid friction pad 5 to disengage from the sides of the first scale plate 11 and the second scale plate 12, and the hand-pushing turntable 22 is held and rotated to drive the rotating rod 21 and the transmission gear 23 to rotate.

After the first scale plates 11 and the second scale plates 12 and the side of the storage frame 1 are fit against the surface of the drawing paper to be formed, the scale data on the surfaces of the first scale plates 11 and the second scale plates 12 are added to the scale data opened on the surface of the storage frame 1 to obtain the measurement value data.
