Description

Technical Field

[0001] This utility model relates to the field of measuring tools, specifically a multifunctional building measuring tool. Background Technology

[0002] Architecture is a space constructed by people using building materials such as mud, bricks, tiles, stone, and wood (in modern times, reinforced concrete and profiles) for living and use. Construction often requires calculation and measurement, which usually requires the use of measuring tools.

[0003] According to publicly available patent 202120762224.1, a multifunctional building calculation and measurement tool, a multifunctional building calculation and measurement tool includes a toolbox. A measuring tape assembly is provided on one side of the inner side of the toolbox, and a plumb line assembly is provided on the surface of the toolbox on the side of the measuring tape assembly. A ruler assembly is provided inside the toolbox on the side of the plumb line assembly. A storage box is installed on the surface of the toolbox, and the interior of the storage box has a cavity. A lid is hinged to the inner wall of the cavity. This utility model not only realizes the wiping function during the use of the measuring tool and the fixing function when the measuring tool is plumb, but also expands the scope of application of the measuring tool.

[0004] In traditional construction and surveying, multifunctional building surveying tools typically rely on rulers or measuring tapes for basic distance measurements. However, in actual construction site scenarios, the length measurement needs of linear structures such as roads, pipelines, and building outlines often involve long distances, complex paths, and curves or irregular routes. Rulers or measuring tapes, limited by their measurement methods (requiring segmented splicing or straightening for measurement) and operational efficiency (requiring multiple people to cooperate and frequent marking and positioning), struggle to quickly and accurately acquire continuous linear distances. This is especially true when dealing with long-span roads, winding pipelines, or irregularly shaped building outlines, where traditional tools are prone to accumulating measurement errors, low efficiency, or even inoperability, failing to fully meet the demands of efficient and accurate linear measurements on construction sites. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a multifunctional building measurement tool. This tool addresses the current problem that in traditional building construction and surveying, multifunctional building measurement tools generally rely on rulers or measuring tapes for basic distance measurement. However, in actual construction site scenarios, the length measurement needs of linear structures such as roads, pipelines, and building outlines often involve long distances, complex paths, and curves or irregular directions. Rulers or measuring tapes are limited by measurement methods (requiring segmented splicing or straightening for measurement) and operational efficiency (requiring multiple people to cooperate and frequent marking and positioning), making it difficult to quickly and accurately obtain continuous linear distances. Especially when facing large-span roads, winding pipelines, or irregular building outlines, traditional tools are prone to problems such as accumulated measurement errors, low efficiency, or even inoperability, failing to fully meet the technical problem of the need for efficient and accurate linear measurement on construction sites.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a multifunctional building measuring tool is designed, including a measuring housing. A tool groove is opened on the surface of the measuring housing, and a cover plate is installed at the opening of the tool groove. A groove is opened at the bottom side of the measuring housing, and a measuring component is arranged inside the groove. Multiple circular grooves are opened on the top side of the measuring housing, and a movable rod extends into the multiple circular grooves. Multiple threaded grooves are opened on the surface of the movable rod, and the multiple threaded grooves are threadedly connected to the fixing bolts that extend into the circular grooves. A handle is fixed to one end of the movable rod that extends out of the circular groove.

[0007] Preferably, the measuring component includes multiple counting shafts, which are respectively installed at both ends inside the groove. A rotating rod is rotatably connected between the multiple counting shafts. A measuring wheel is installed on the outside of the rotating rod, and an annular groove is formed around the surface of the measuring wheel.

[0008] Preferably, a placement groove is provided in the middle of one side of the measuring housing, and a baffle is installed at the opening of the placement groove.

[0009] Preferably, a material valve is installed at the top of the groove, the top of the material valve is connected to a placement trough, and the bottom of the material valve is connected to a material pipe, which is correspondingly arranged with the annular groove on the surface of the measuring wheel.

[0010] Preferably, the surface of the measuring housing is provided with a mounting groove, and a lap counter is installed inside the mounting groove.

[0011] Preferably, a cavity is provided on one side of the measuring housing, a fixed shaft is installed inside the cavity, one end of a spiral spring is installed outside the fixed shaft, and an annular plate is fixed to the other end of the spiral spring.

[0012] Preferably, one end of the measuring scale is wound around the outside of the annular plate, and the other end of the measuring scale is fixed with a pull block through a through hole opened on the surface of the measuring housing.

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

[0014] 1. This utility model integrates distance measurement and line setting functions by combining a measuring wheel, a counting shaft, and a material valve. In distance measurement mode, the user can quickly pull the moving rod out of the measuring housing and lock it to the required length. The measuring wheel at the bottom of the measuring housing is then placed stably on the ground. As the measuring wheel rotates, its built-in counting shaft and counting device synchronously record the number of rotations. Combined with the preset circumference parameter of the measuring wheel, the measurement distance is automatically calculated by multiplying the number of rotations by the circumference, achieving fast and accurate linear distance measurement. For the line setting needs of construction sites, an annular powder storage tank is used. The annular groove on the surface of the measuring wheel can hold marking materials such as lime powder and talcum powder. When performing line setting operations, the operator only needs to evenly fill the tank with powder. As the equipment moves along the predetermined path, the powder in the tank is evenly spread by centrifugal force, completing the line setting operation simultaneously. The path marking and distance measurement system integrates the mechanical transmission of the distance measuring mechanism and the powder spreading function of the line laying mechanism through a measuring wheel. This avoids the cumbersome process of alternating between distance measuring and line laying tools in traditional operations, improving on-site work efficiency. It is especially suitable for complex construction scenarios such as road marking, pipeline laying, and building outline positioning, where distance measurement and path marking need to be completed simultaneously. It solves the problem that rulers or tape measures are limited by measurement methods (requiring segment splicing or straightening for measurement) and operational efficiency (requiring multiple people to cooperate and frequent marking and positioning), making it difficult to quickly and accurately obtain continuous linear distances. Especially when facing large-span roads, winding pipelines, or irregular building outlines, traditional tools are prone to problems such as accumulated measurement errors, low efficiency, or even inoperability, failing to fully meet the technical needs of engineering sites for efficient and accurate linear measurement.

[0015] 2. This utility model combines a movable rod, a threaded groove, and a measuring scale. When measurement or layout work is required, the movable rod of the measuring wheel can be extended outward from inside the measuring housing. The operator only needs to hold the handle at the top of the movable rod to maintain a standing posture and move the measuring wheel device flexibly. Moreover, in the extended state, the device can be used in conjunction with the built-in measuring scale. The operator can hold the handle with one hand to press the front end of the measuring housing against the surface of the object to be measured, and simultaneously pull the measuring scale to smoothly move it out of the housing. After the measurement is completed, the total size of the target object can be quickly obtained by adding the length value displayed on the scale to the fixed length of the measuring housing itself. The entire process can be completed by a single person, improving the measurement efficiency and convenience in complex scenarios and further increasing functionality. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: A multifunctional building surveying tool, see [link / reference] Figures 1 to 3The device includes a measuring housing 1. A tool groove 101 is formed on the surface of the measuring housing 1, and a cover plate is installed at the opening of the tool groove 101. A groove 208 is formed on the bottom side of the measuring housing 1, and a measuring component is disposed inside the groove 208. Multiple circular grooves 202 are formed on the top of the other side of the measuring housing 1, and a movable rod 212 extends into each of the circular grooves 202. Multiple threaded grooves 205 are formed on the surface of the movable rod 212, and the threaded grooves 205 are threadedly connected to fixing bolts 203 extending into the circular grooves 202. A handle 204 is fixed to one end of the movable rod 212 extending out of the circular groove 202. In distance measurement mode, the user can quickly pull the movable rod 212 out of the measuring housing 1 and connect it to the threaded holes at different positions on the surface of the movable rod 212 via fixing bolts 203, thereby locking the movable rod 212 to the required length. Then, the measuring wheel 2 at the bottom of the measuring housing 1 is placed stably on the ground. When the measuring wheel 2 rotates, its built-in counting shaft 206 and the counting device 201 synchronously record the number of rotations. Combined with the preset circumference parameter of the measuring wheel 2, the measured distance is automatically obtained by calculating the number of rotations × circumference, realizing fast and accurate linear distance measurement. For the needs of construction site layout, this method is adopted. The annular powder storage tank, with an annular groove 209 on the surface of the measuring wheel 2, can hold marking materials such as lime powder and talc powder. During line marking operations, the operator only needs to open the material valve 213, allowing the powder in the storage tank 210 to be filled into the tank through the material pipe 214. As the equipment moves along the predetermined path, the powder in the tank is evenly spread by centrifugal force, simultaneously completing path marking and distance measurement. The mechanical transmission of the distance measuring mechanism and the powder spreading function of the line marking mechanism are integrated through the measuring wheel 2, avoiding the cumbersome process of alternating between distance measuring and line marking tools in traditional operations, thus improving on-site operation efficiency. Efficiency is particularly suitable for complex construction scenarios that require simultaneous distance measurement and path marking, such as road marking, pipeline laying, and building outline positioning. It solves the problem that rulers or tape measures are limited by measurement methods (requiring segmented splicing or straightening for measurement) and operational efficiency (requiring multiple people to cooperate and frequent marking and positioning), making it difficult to quickly and accurately obtain continuous linear distances. Especially when facing large-span roads, winding pipelines, or irregular building outlines, traditional tools are prone to problems such as accumulated measurement errors, low efficiency, or even inoperability, and cannot fully meet the technical problems of the engineering site's demand for efficient and accurate linear measurement.

[0022] For details, see Figure 2 The measuring component includes multiple counting shafts 206, which are respectively installed at both ends inside the groove 208. A rotating rod 207 is rotatably connected between the multiple counting shafts 206. A measuring wheel 2 is installed on the outside of the rotating rod 207. An annular groove 209 is formed around the surface of the measuring wheel 2.

[0023] Further, see Figure 2A placement groove 210 is provided in the middle of one side of the measuring housing 1, and a baffle 211 is installed at the opening of the placement groove 210.

[0024] It is worth noting that, see Figure 2 A material valve 213 is installed at the top of the groove 208. The top of the material valve 213 is connected to the placement trough 210, and the bottom of the material valve 213 is connected to the material pipe 214. The material pipe 214 is set to correspond to the annular groove 209 on the surface of the measuring wheel 2.

[0025] It is worth noting that, see Figure 1 The surface of the measuring housing 1 is provided with an installation groove, and a lap counter 201 is installed inside the installation groove.

[0026] It is worth mentioning that, see Figure 3 The measuring housing 1 has a cavity 301 on one side, and a fixed shaft 302 is installed inside the cavity 301. One end of a spiral spring 303 is installed outside the fixed shaft 302, and the other end of the spiral spring 303 is fixed with an annular plate 304. When measurement or line laying is required, the movable rod 212 of the measuring wheel 2 can be extended outward from inside the measuring housing 1. The operator only needs to hold the handle 204 at the top of the movable rod 212 to maintain a standing posture and move the measuring wheel 2 device flexibly. Moreover, in the extended state, the device can be used in conjunction with the built-in measuring ruler 305. The operator can hold the handle 204 with one hand to press the front end of the measuring housing 1 against the surface of the object to be measured, and simultaneously pull the measuring ruler 305 to move it smoothly out of the housing. After the measurement is completed, the total size of the target object can be quickly obtained by adding the length value displayed by the ruler to the fixed length of the measuring housing 1 itself. The entire process can be completed by a single person.

[0027] It is worth emphasizing that, see Figure 1 and Figure 3 One end of a measuring scale 305 is wound around the outside of the annular plate 304, and the other end of the measuring scale 305 is fixed with a pull block 3 through a through hole 306 opened on the surface of the measuring housing 1.

[0028] It should be noted that the model of the lap counter 201 is an OMRON E6B2 incremental rotary encoder. In the ranging equipment, the encoder can be connected to the lap counter shaft 206. When the measuring wheel 2 rotates, the lap counter shaft 206 drives the encoder to rotate, and the encoder outputs a corresponding pulse signal. The number of rotations can be recorded by the counting circuit.

[0029] In the measurement equipment solution involved in this application, a battery module can be installed inside the measuring housing 1. By placing the battery inside the measuring housing 1, the battery is used as a power source to provide a stable and continuous power supply to the coil counter 201, so as to ensure the normal operation of the coil counter 201 during the measurement process.

[0030] When using a multi-functional building surveying tool, in distance measurement mode, the user can quickly pull the movable rod 212 out of the measuring housing 1 and connect it to the threaded holes at different positions on the surface of the movable rod 212 via fixing bolts 203, thereby locking the movable rod 212 to the required length. Then, the measuring wheel 2 at the bottom of the measuring housing 1 is placed stably on the ground. When the measuring wheel 2 rotates, its built-in circumference counting shaft 206 and circumference counter 201 synchronously record the number of rotations. Combined with the preset circumference parameter of the measuring wheel 2, the number of rotations multiplied by the circumference is calculated. The calculation method automatically yields the measurement distance, achieving rapid and accurate linear distance measurement. For construction site layout needs, an annular powder storage tank is used. The annular groove 209 on the surface of the measuring wheel 2 can hold marking materials such as lime powder and talc powder. When performing layout operations, the operator only needs to open the material valve 213, allowing the powder in the storage tank 210 to be filled into the tank through the material pipe 214. As the equipment moves along the predetermined path, the powder in the tank is evenly distributed by centrifugal force, simultaneously completing path marking and distance measurement. The powder spreading function of the mechanical transmission and line-laying mechanism is integrated through the measuring wheel 2, avoiding the cumbersome process of alternating between distance measuring tools and line-laying tools in traditional operations, thus improving on-site work efficiency. It is especially suitable for complex construction scenarios that require simultaneous distance measurement and path marking, such as road marking, pipeline laying, and building outline positioning. When measurement or line-laying operations are required, the movable rod 212 of the measuring wheel 2 can be extended outward from the inside of the measuring housing 1. The operator only needs to hold the handle 204 at the top of the movable rod 212 to maintain a standing posture and move the measuring wheel 2 device flexibly. Moreover, in the extended state, the device can be used in conjunction with the built-in measuring ruler 305. The operator can hold the handle 204 with one hand to press the front end of the measuring housing 1 against the surface of the object to be measured, and simultaneously pull the measuring ruler 305 to smoothly move it out of the housing. After the measurement is completed, the total size of the target object can be quickly obtained by simply adding the length value displayed on the ruler to the fixed length of the measuring housing 1 itself. The entire process can be completed by a single person.
