Description

Technical Field

[0001] The utility model relates to the technical field of wire laying measuring devices, in particular to a portable wire laying measuring device. Background Technique

[0002] Both engineering construction and project cost evaluation are based on measured data. Many measuring instruments are needed in the measuring process, and the most commonly used one is the wire laying measuring device. The structure of the existing wire laying measuring device is relatively simple. The wire laying measuring device has a certain measuring range, and multiple different specifications are often divided according to different measuring ranges.

[0003] During the use of the traditional wire laying device, no support is provided for the measurement. When the measuring wire ruler is in use, it will fall downward by its own weight and contact the base. During the process of winding and unwinding the measuring wire ruler, it contacts and rubs against the base, increasing the loss of the measuring wire ruler. After the measuring wire ruler contacts and rubs against the base for a long time, it will break, shortening the service life of the measuring wire ruler. When the measuring wire ruler is wound up, it is also prone to side-overwinding. When the measuring wire ruler is wound up in a rolled-up state, it is easy to deform. Therefore, a portable wire laying measuring device is needed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems raised in the above background technique.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A portable wire laying measuring device includes a frame rod. A winding assembly is connected to the right side of the frame rod. The winding assembly includes two docking plates. A slide rail is movably installed inside the docking plate, and a connecting plate is connected inside the slide rail. A support plate is connected to the right side of the connecting plate. A driving motor is installed inside the support plate. The output end of the driving motor penetrates through the connecting plate and is fixedly connected to a winding roller. A battery pack is connected to the top end of the support plate. A pressing-down assembly is installed at the bottom end of the front surface of the frame rod. The pressing-down assembly includes a seat frame. A runner is rotatably connected to the bottom end of the inner wall of the seat frame. A displacement block is embedded in the inner wall of the seat frame through a through groove, and a pressing-down wheel is rotatably connected to the inner wall of the displacement block. A smoothing assembly is arranged on the left side of the seat frame.

[0007] Preferably, two rectangular block ends are symmetrically connected to the left and right sides of the displacement block, and the rectangular block ends are embedded in the inner wall of the through groove of the seat frame through a guide groove. The rectangular block ends of the displacement block can be limited through the guide groove of the seat frame.

[0008] Preferably, a threaded spindle is rotatably connected to the top end of one of the displacement blocks, and the top end of the threaded spindle penetrates through the outside of the seat frame through a threaded hole. The movement of the displacement block can change the position of the pressing-down wheel, thereby adjusting the distance between the pressing-down wheel and the runner.

[0009] Preferably, the flattening component includes a bottom plate fixedly connected to the bottom end of the front surface of the seat frame. An active plate is embedded in the inner wall of the bottom plate through a guide groove. Two positioning shafts are symmetrically connected to the top end of the active plate, and the positioning shafts pass through the inside of the balance plate through through holes. A return spring is sleeved outside the positioning shafts, and the bottom end of the return spring is fixedly connected to the balance plate. A flattening block is connected to the left side of the balance plate. When the balance plate moves, it can drive the flattening block to move and fit on the surface of the measuring line scale. When the measuring line scale moves, the flattening block can press down and flatten the rolled edge of the measuring line scale.

[0010] Preferably, the left side of the bottom plate is designed with a V-shaped inner groove, and a guide wheel is rotatably connected to the inner wall of the V-shaped inner groove. Through the V-shaped inner groove design of the bottom plate, the measuring line scale can be guided, so that the measuring line scale can quickly enter between the balance plate and the active plate.

[0011] Preferably, the slide rail is composed of a cylindrical end and a plate end. The slide rail is embedded in the docking plate through a guide groove, and the guide groove of the docking plate can guide the slide rail.

[0012] Preferably, a strip-shaped through groove is formed on the side of the docking plate, and a locking bolt is inserted into the strip-shaped through groove. The shaft end of the locking bolt is inserted into the connecting plate through a threaded hole. By passing the locking bolt through the docking plate and inserting it into the threaded hole of the connecting plate, the stability of the connecting plate after adjustment is ensured.

[0013] The utility model at least has the following beneficial effects:

[0014] 1. By setting the pressing component and the flattening component, the suspension, flattening, winding and unwinding of the measuring line scale are realized. Compared with the traditional structure, in this device, the wire measuring device is placed between the rotating wheel and the pressing wheel, so that the displacement block moves in the guide groove of the seat frame, changing the distance between the pressing wheel and the rotating wheel. The wire measuring device is suspended, guided, wound and unwound by the rotating wheel and the pressing wheel, reducing the probability of contact and friction between the measuring line scale and the base during the winding and unwinding process, reducing the loss of the measuring line scale. During winding, the flattening block can fit on the rolled edge of the measuring line scale for flattening operation, avoiding deformation of the measuring line scale caused by winding.

[0015] 2. By setting the winding component, the automatic winding of the measuring line scale is realized. In this device, the output end of the driving motor drives the winding roller to rotate, and the measuring line scale can be wound, ensuring the winding efficiency of the measuring line scale. By moving the slide rail in the guide groove of the docking plate, the height of the winding roller can be conveniently adjusted independently to meet the use requirements of various sites. At the same time, the U-shaped structure design of the frame rod facilitates the staff to carry and lift the frame rod. Description of the Drawings

[0024] Two rectangular block ends are symmetrically connected to the left and right sides of the displacement block 33 , and the rectangular block ends are embedded in the inner wall of the through groove of the seat frame 31 through the guide groove.

[0025] A threaded shaft 35 is rotatably connected to the top of one of the displacement blocks 33 , and the top of the threaded shaft 35 passes through the outside of the seat frame 31 through a threaded hole.

[0026] The smoothing component 4 includes a bottom plate 41 connected and fixed to the bottom end of the front side of the seat frame 31, a movable plate 43 is embedded in the inner wall of the bottom plate 41 through a guide groove, two positioning shafts 44 are symmetrically connected to the top of the movable plate 43, and the positioning shafts 44 pass through the inside of the balance plate 45 through through holes, a return spring 47 is sleeved on the outside of the positioning shaft 44, and the bottom end of the return spring 47 is connected and fixed to the balance plate 45, and a smoothing block 46 is connected to the left side of the balance plate 45.

[0027] The left side of the bottom plate 41 is designed as a V-shaped inner groove, and the inner wall of the V-shaped inner groove is rotatably connected to a guide wheel 42 .

[0028] The slide rail 22 is composed of a cylindrical end and a plate end, and the slide rail 22 is embedded in the docking plate 21 through a guide groove.

[0029] A strip-shaped through groove is formed on the side of the docking plate 21 , and a locking bolt 24 is inserted into the strip-shaped through groove. The shaft end of the locking bolt 24 is inserted into the connection plate 23 through a threaded hole.

[0030] The rectangular block end of the displacement block 33 can be limited by the guide groove of the seat frame 31, so that the displacement block 33 can stably move up and down in the through groove of the seat frame 31. By twisting and rotating the threaded spindle 35, the threaded spindle 35 can move in the threaded hole of the seat frame 31, and then push the displacement block 33.

At the same time, the movable design of the connecting plate 23 can facilitate the adjustment of the height of the winding roller 28.

[0031] Working principle: According to the attached Figure 1 And the attached Figure 4 As shown, when the measuring wire scale is wound, the driving motor 26 can be started, and the output end of the driving motor 26 drives the winding roller 28 to rotate. The winding roller 28 can pull and wind the measuring wire scale. At the same time, according to the attached Figure 2 And the attached Figure 3 As shown, when the measuring wire scale moves between the balance plate 45 and the movable plate 43, the resilience of the return spring 47 can push the balance plate 45 downward, so that the balance plate 45 drives the smoothing block 46 to fit and contact the surface of the measuring wire scale. When the measuring wire scale moves, the smoothing block 46 smooths the rolled edge of the measuring wire scale. The smoothed measuring wire scale passes between the lower pressing wheel 34 and the rotating wheel 32, and the lower pressing wheel 34 and the rotating wheel 32 can guide the measuring wire scale, so as to assist in winding the measuring wire scale.
