Description

Technical Field

[0001] This utility model relates to the technical field of engineering cost measurement tools, and in particular to a structure for an engineering cost measurement ruler. Background Technology

[0002] The construction cost measuring ruler is an important tool used in the field of construction cost estimation. It usually has precise scales and multiple measurement functions, and can accurately measure the length, width, height and other dimensional parameters of buildings. Construction cost measuring rulers are generally made of durable materials, making them easy to carry and operate. In the process of calculating construction costs, the actual dimensional data of buildings are obtained by using the measuring ruler, which provides a basis for accurately estimating material usage, labor costs and the total cost of the project.

[0003] Existing technologies, such as the utility model patent with publication number CN208952810U, disclose an engineering cost measuring ruler. This patent uses a magnetic ring concentrically arranged with the winding shaft on the side of the measuring ruler body near the connecting rod, and a locking groove for the magnetic ring to be locked in place. On the side of the connecting rod near the grip post, there is a magnetic block that attracts the magnetic ring so that the side of the connecting rod near the grip post abuts against the measuring ruler body, and a locking groove for the magnetic block to be locked in place. This solves the problem that in existing engineering cost measuring rulers, the connecting rod is prone to rotation due to bumps and shaking when carried, causing the grip post to face away from the measuring ruler body, thus failing to limit the measuring ruler.

[0004] When using a measuring ruler to measure a building, there is a problem with existing measuring rulers, such as the one mentioned above. When using the measuring ruler, it is fixed by a fixing hook at the end of the ruler. When fixing it, nails and other hardware need to be nailed to the wall so that the operator can hang the fixing hook in the designated area. This makes the preparation for using the measuring ruler quite cumbersome. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the existing technology requires nails and other hardware to be nailed to the wall for the operator to hang the fixing hook in the designated area, which makes the preparation for the use of the measuring ruler cumbersome. Therefore, this utility model proposes a new structure for engineering cost measuring ruler.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an engineering cost measuring ruler structure, including a bracket, a rotating shaft, and a handle. The rotating shaft is rotatably connected to the inner wall of the bracket, and the handle is installed at one end of the rotating shaft. A scale is wound around the surface of the rotating shaft, and the scale is located inside the bracket. The movable end of the scale penetrates the lower surface of the bracket. A connecting component is provided on the surface of the scale. The connecting component includes a connecting frame. An adsorption component is provided on the side surface of the connecting frame. The adsorption component includes an assembly plate. The assembly plate is fixedly connected to the side surface of the connecting frame. A suction cup is fixedly connected to the side of the assembly plate away from the scale. An air cavity is opened on the surface of the assembly plate. A load-bearing plate is slidably connected to the inner wall of the air cavity. A limit spring is fixedly connected to the side surface of the load-bearing plate. A sealing plug is fixedly connected to the side of the load-bearing plate away from the limit spring. A pressing frame is slidably connected to the inner wall of the air cavity.

[0007] Preferably, the suction cup is connected to the inner wall of the air chamber, and there are two suction cups arranged symmetrically about the assembly plate. The suction cups can be used to attach the movable end of the ruler to a smooth and flat wall in a sealed state.

[0008] Preferably, the side of the limiting spring away from the load-bearing plate is fixedly connected to the inner wall of the air chamber, and the sealing plug is slidably connected to the inner wall of the air chamber. The limiting spring can constrain the position of the load-bearing plate to ensure the stability of the load-bearing plate in the sealed state.

[0009] Preferably, the pressing frame is fixedly connected to the surface of the load-bearing plate, and the pressing frame penetrates the side surface of the assembly plate. The pressing frame allows the operator to adjust the position of the load-bearing plate.

[0010] Preferably, the connecting assembly further includes a U-shaped frame, which is fixedly connected to the surface of the scale. A limiting shaft is rotatably connected to the inner wall of the U-shaped frame. The connecting frame is fixedly connected to the surface of the limiting shaft. A main button is fixedly connected to the surface of the scale. A secondary button is fixedly connected to the side of the assembly plate near the scale. The rotation axis of the limiting shaft can be limited by the U-shaped frame to ensure that the limiting shaft rotates in a specified direction.

[0011] Preferably, the arc surface of the U-shaped frame is in contact with the surface of the assembly plate, the side of the connecting frame near the scale is arc-shaped, and the connecting frame is in contact with the side surface of the U-shaped frame. Through the cooperation of the connecting frame and the limiting shaft, the rotation direction of the assembly plate can be guided.

[0012] Preferably, there are two main buttons, which are arranged symmetrically about the scale. The number of auxiliary buttons matches the number of main buttons, and the auxiliary buttons are inserted into the inner wall of the main buttons. The position of the assembly plate can be restricted by the cooperation of the main buttons and auxiliary buttons.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting a connecting component, the movable end of the measuring ruler can be quickly limited, thereby reducing the need for nails or other hardware to fix the measuring ruler during use, which leads to cumbersome fixing operations, and further improving the convenience of using the measuring ruler.

[0022] Please see Figures 1-5This utility model provides a technical solution: an engineering cost measuring ruler structure, including a bracket 1, a rotating shaft 2 and a handle 3. The rotating shaft 2 is rotatably connected to the inner wall of the bracket 1. The handle 3 is installed at one end of the rotating shaft 2. A scale 4 is wound around the surface of the rotating shaft 2. The scale 4 is located inside the bracket 1. The movable end of the scale 4 passes through the lower surface of the bracket 1. A connecting component 5 is provided on the surface of the scale 4. The connecting component 5 includes a connecting frame 53. An adsorption component 6 is provided on the side surface of the connecting frame 53.

[0023] The specific settings and functions of the connecting component 5 and the adsorption component 6 will be explained below.

[0024] In this embodiment: the adsorption component 6 includes an assembly plate 61, which is fixedly connected to the side surface of the connecting frame 53. A suction cup 62 is fixedly connected to the side of the assembly plate 61 away from the scale 4. An air cavity 63 is opened on the surface of the assembly plate 61. A load-bearing plate 64 is slidably connected to the inner wall of the air cavity 63. A limit spring 65 is fixedly connected to the side surface of the load-bearing plate 64. A sealing plug 66 is fixedly connected to the side of the load-bearing plate 64 away from the limit spring 65. A pressing frame 67 is slidably connected to the inner wall of the air cavity 63.

[0025] Specifically, the suction cup 62 is connected to the inner wall of the air chamber 63. There are two suction cups 62, which are arranged symmetrically about the assembly plate 61. The movable end of the ruler 4 can be attached to a smooth and flat wall in a closed state through the suction cups 62.

[0026] Specifically, the side of the limiting spring 65 away from the load plate 64 is fixedly connected to the inner wall of the air cavity 63, and the sealing plug 66 is slidably connected to the inner wall of the air cavity 63.

[0027] In this embodiment, the position of the load-bearing plate 64 can be constrained by the limiting spring 65 to ensure the stability of the load-bearing plate 64 in the sealed state.

[0028] Specifically, the pressing frame 67 is fixedly connected to the surface of the load-bearing plate 64. The pressing frame 67 penetrates the side surface of the assembly plate 61. The pressing frame 67 allows the operator to adjust the position of the load-bearing plate 64.

[0029] In this embodiment: the connecting component 5 also includes a U-shaped frame 51, which is fixedly connected to the surface of the ruler 4. The inner wall of the U-shaped frame 51 is rotatably connected to a limiting shaft 52. The connecting frame 53 is fixedly connected to the surface of the limiting shaft 52. A main button 54 is fixedly connected to the surface of the ruler 4. A secondary button 55 is fixedly connected to the side of the assembly plate 61 near the ruler 4.

[0030] In this embodiment, the rotation axis 2 of the limiting shaft 52 can be limited by the U-shaped frame 51 to ensure that the limiting shaft 52 rotates in a specified direction.

[0031] Specifically, the arc surface of the U-shaped frame 51 contacts the surface of the assembly plate 61, the side of the connecting frame 53 near the scale 4 is arc-shaped, and the connecting frame 53 contacts the side surface of the U-shaped frame 51. Through the cooperation of the connecting frame 53 and the limiting shaft 52, the rotation direction of the assembly plate 61 can be guided.

[0032] Specifically, there are two main buttons 54, which are arranged symmetrically about the scale 4. The number of secondary buttons 55 matches the number of main buttons 54, and the secondary buttons 55 are inserted into the inner wall of the main buttons 54.

[0033] In this embodiment, the position of the assembly plate 61 can be restricted by the cooperation of the main button 54 and the secondary button 55.

[0034] Working principle: When measuring a building with the measuring ruler, if the building wall is relatively smooth, ensure that the secondary button 55 on the assembly plate 61 is fixed on the main button 54. Press the scale 4 on the assembly plate 61. The scale 4 pushes the assembly plate 61, which squeezes the suction cup 62. The suction cup 62 is deformed by the squeeze and expels the gas inside. After the gas is expelled, the suction cup 62 forms a negative pressure and stably adheres to the wall. It also works with the assembly plate 61 and the connecting component 5 to fix the movable end of the scale 4. When the building wall being measured is not smooth, pull the assembly plate 61. The assembly plate 61 pulls the secondary button 55, which... When buckle 55 disengages from main button 54, assembly plate 61 continues to be stressed and rotates under the guidance of connecting frame 53, limiting shaft 52 and U-shaped frame 51. When assembly plate 61 rotates to its maximum angle, the end of assembly plate 61 abuts against the surface of U-shaped frame 51, and then the bent U-shaped frame 51 can be hooked onto the corner of the wall to fix the end of the ruler 4. By setting connecting component 5, the movable end of the measuring ruler can be quickly limited, thereby reducing the need for nails and other hardware to fix the measuring ruler during use, which leads to cumbersome fixing operations, and further improving the convenience of using the measuring ruler.
