Description

Technical Field

[0001] This utility model relates to the field of building inspection technology, specifically to a measurement tool for unit-by-unit acceptance, used to quickly and accurately collect relevant data during indoor unit-by-unit acceptance, and is particularly suitable for determining the location of measurement points and measuring indoor net height. Background Technology

[0002] With the development of the times and the advancement of technology, the actual measurement of indoor unit acceptance still faces time-consuming and labor-intensive issues. In the past, indoor net height required the use of leveling rods, tape measures, or laser rangefinders. Tape measures are prone to fatigue due to repeated pulling and stretching; leveling rods are heavy and difficult to operate when stretched, and are prone to shaking, leading to fatigue and reduced accuracy; the selection of 50cm measurement points for unit acceptance usually requires multiple determinations using tools such as tape measures; when using laser rangefinders to measure indoor net height, the rangefinder needs to be placed on the ground, requiring the inspector to stand up and squat down multiple times when measuring a large number of units, making the measurement process cumbersome and reducing efficiency. Furthermore, to accurately read and interpret height data, inspectors need to bend over or squat continuously, resulting in high labor intensity and low work efficiency, ultimately affecting both inspection efficiency and accuracy.

[0003] Therefore, during the process of collecting actual measurement data for unit acceptance, it is necessary to adopt practical and effective tools to assist in the testing, and to take effective improvement measures to address the existing problems in the testing, so as to comprehensively improve the efficiency of data collection during unit acceptance. Utility Model Content

[0004] The purpose of this utility model is to provide a tool for actual measurement and verification during household acceptance, so as to solve the problems mentioned in the background art above:

[0005] (1) How to quickly and accurately determine the location of measurement points and collect relevant data in the process of household acceptance and actual measurement, which are characterized by cumbersome operation, low detection efficiency, high labor intensity of detection personnel and affected detection accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A tool for actual measurement and verification during household acceptance;

[0008] Includes a base, a fixed tube, a stamp, a pressure rod, a rotating sleeve, and a distance measuring assembly;

[0009] The lower end face of the base has an assembly groove for the stamp to move up and down. A fixing tube is fixedly connected to the upper side of the base. The inner hole of the fixing tube communicates with the assembly groove of the base. The pressure rod is engaged with the inner hole of the fixing tube. The lower end of the pressure rod extends into the assembly groove of the base and is fixedly connected to the upper end face of the stamp.

[0010] The rotating sleeve is fitted onto the outside of the fixed tube. The rotating sleeve can rotate freely along the axis of the fixed tube. The ranging component is mounted on the rotating sleeve and includes at least a rangefinder.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the middle part of the pressure rod is provided with a spline that restricts the pressure rod to reciprocate only along the axial direction of the fixed tube, and the inner wall of the fixed tube is provided with a spline groove that mates with the spline of the pressure rod.

[0013] Furthermore, the inner wall of the rotating sleeve is provided with several sets of limiting protrusions, each set of limiting protrusions includes four limiting protrusions, the four limiting protrusions in the same set are at the same horizontal height, and there is a 90° included angle between two adjacent limiting protrusions. Limiting grooves are respectively opened on the outer wall of the fixed tube corresponding to the positions of several sets of limiting protrusions.

[0014] Furthermore, the ranging assembly also includes a bracket, which is fixed to the outer wall of the rotating sleeve, and the rangefinder is mounted on the bracket.

[0015] Furthermore, it also includes a return spring. The upper end of the pressure rod extends out of the upper side of the fixed tube. A positioning protrusion is fixedly connected to the side wall of the pressure rod extending out of the fixed tube. The return spring is fitted on the outer wall of the pressure rod. The upper end of the return spring abuts against the lower end face of the positioning protrusion, and the lower end of the return spring abuts against the upper end face of the fixed tube.

[0016] Furthermore, it also includes two sets of spacer components, which are located on both sides of the rotating sleeve. Each spacer component includes a spacer rod, one end of which is connected to the outside of the rotating sleeve.

[0017] Furthermore, the spacer assembly also includes a hinge seat, which is fixedly connected to the outer wall of the rotating sleeve. One end of the spacer rod is hinged to the hinge seat, and the other end of the spacer rod can rotate outward from the rotating sleeve.

[0018] Furthermore, the hinge seat of the spacer assembly is provided with a stop bar, which restricts the spacer rod from rotating to a horizontal position.

[0019] This structure allows the stamp to move smoothly within the mounting slot, providing a foundation for subsequent marking of measurement points on the ground. The fixing tube provides a channel for the installation and movement of components such as the pressure rod, ensuring coordinated operation between all parts.

[0020] The spline and spline groove fit of the pressure rod ensures that it can only move axially, improving the stability of movement. The lower end of the pressure rod extends into the mounting groove of the base and is fixed to the upper surface of the stamp by a threaded fit. When the pressure rod moves, it can drive the stamp to move synchronously.

[0021] The function of the return spring is to automatically reset the pressure rod after it is pushed down by force, making it convenient for the next operation.

[0022] The rotating sleeve is fitted onto the outside of the fixed tube. The rotating sleeve can rotate freely along the axis of the fixed tube. The limiting protrusion cooperates with the limiting groove of the fixed tube and can play a limiting role after the rotating sleeve rotates 90°.

[0023] The bracket of the ranging component can lift the laser rangefinder to a certain height for convenient measurement operations, while the rotatability of the rotating sleeve allows the laser rangefinder to be flexibly adjusted in angle.

[0024] The two sets of spacer components have a 180° angle between their spacer bars, and the length of the spacer bar is 50cm. The design of the spacer components enables the rapid determination of the position of the 50cm measurement point, and the 50cm length of the spacer bar can be directly used as the basis for determining the measurement point.

[0025] This unit-by-unit acceptance measurement tool effectively determines the location and marking of measurement points. The bracket supports the laser rangefinder at a certain height, allowing for measurement of the distance from this height to the floor slab. This distance, combined with the distance from the ground to the laser rangefinder, gives the total distance from the ground to the floor slab. The bracket also allows the laser rangefinder to be adjusted to a suitable height for the inspector, enabling the measurement of building floor heights using a ruler. This eliminates the need for workers to repeatedly squat and stand up during floor height measurements, thus improving efficiency. Furthermore, it reduces the manpower and resources required for unit-by-unit acceptance data collection, saving costs.

[0026] The beneficial technical effects of this household acceptance measurement tool are as follows:

[0027] (1) The two sets of interval components can quickly determine the 50cm measurement point for household acceptance and mark the ground with a stamp, avoiding the tedious operation of using measuring tape and other tools to determine the measurement point multiple times in the traditional method, thus improving work efficiency.

[0028] (2) The bracket can support the laser rangefinder at a certain height, and then the distance from this height to the floor slab can be obtained by measurement. This distance, plus the distance from the ground to the laser rangefinder, can be used to calculate the distance from the ground to the floor slab, realizing rapid data acquisition. At the same time, the bracket can be used to adjust the laser rangefinder to a suitable height for the inspector, and with the help of a ruler, the building floor height can be measured, preventing the staff from having to squat and stand up multiple times when measuring the building floor height, further improving the inspection efficiency.

[0029] (3) It reduces the labor intensity of testing personnel due to repeated pulling of the measuring tape, multiple standing up and squatting, and bending over, making the testing work easier.

[0030] (4) It reduces the manpower and material resources consumed in collecting data for household acceptance and lowers the testing cost. Attached Figure Description

[0042] The tools for this unit acceptance test include a base 100, a fixing tube 200, a stamp 400, a pressure rod 300, a return spring 500, a rotating sleeve 600, a distance measuring component, and two sets of interval components.

[0043] The base 100 is generally cylindrical. The lower end face of the base 100 has an assembly groove 110 for the stamp 400 to move up and down. The fixing tube 200 is welded and fixed to the upper side of the base 100. The inner hole of the fixing tube 200 is connected to the assembly groove 110 of the base 100.

[0044] The upper end of the pressure rod 300 extends out of the upper side of the fixing tube 200. A positioning protrusion ring 310 is welded and fixed to the side wall of the pressure rod 300 extending out of the upper side of the fixing tube 200. The pressure rod 300 is engaged with the inner hole of the fixing tube 200. A spline 320 is provided in the middle of the pressure rod 300 to restrict the pressure rod 300 to reciprocate only in the axial direction of the fixing tube 200. A spline groove 210 is provided on the inner wall of the fixing tube 200 to engage with the spline 320 of the pressure rod 300. The lower end of the pressure rod 300 extends into the assembly groove 110 of the seat 100 and is fixed to the upper end face of the stamp 400 by thread engagement.

[0045] The return spring 500 is fitted on the outer wall of the pressure rod 300. The upper end of the return spring 500 abuts against the lower end face of the positioning protrusion ring 310, and the lower end of the return spring 500 abuts against the upper end face of the fixing tube 200.

[0046] The rotating sleeve 600 is fitted onto the outside of the fixed tube 200. The rotating sleeve 600 can rotate freely along the axis of the fixed tube 200. The ranging component is mounted on the rotating sleeve 600. The inner wall of the rotating sleeve 600 is provided with three sets of limiting protrusions 610. Each set of limiting protrusions 610 includes four limiting protrusions 610. The limiting protrusions 610 and the inner wall of the rotating sleeve 600 are smoothly transitioned. The four limiting protrusions 610 in the same set are at the same horizontal height. There is a 90° angle between two adjacent limiting protrusions 610. The outer wall of the fixed tube 200 is provided with limiting grooves (not shown in the figure) corresponding to the positions of the limiting protrusions 610. Whenever the rotating sleeve 600 rotates 90° relative to the fixed tube 200, the limiting protrusions 610 will cooperate with the limiting grooves of the fixed tube 200, which can play a limiting role after the rotating sleeve 600 rotates 90°.

[0047] The ranging assembly includes a laser rangefinder 710 and a bracket 720. The bracket 720 is fixed to the outer wall of the rotating sleeve 600, and the laser rangefinder 710 is mounted on the bracket 720.

[0048] Two sets of spacer components are located on both sides of the rotating sleeve 600. Each spacer component includes a hinge seat 810 and a spacer rod 820. One end of the spacer rod 820 is connected to the outside of the rotating sleeve 600. The hinge seat 810 is fixedly connected to the outer wall of the rotating sleeve 600. One end of the spacer rod 820 is hinged to the hinge seat 810. The other end of the spacer rod 820 can rotate outward from the rotating sleeve 600. A stop bar 811 is provided on the hinge seat 810. The stop bar 811 restricts the spacer rod 820 from rotating to a horizontal position. The spacer rods 820 of the two sets of spacer components have a 180° included angle. The length of the stop bar 811 is 50cm.

[0049] When using this tool, during the actual measurement and data collection for unit acceptance, the 50cm measurement point for unit acceptance can be quickly determined and marked on the ground. The bracket 720 can support the laser rangefinder 710 at a certain height. Then, the distance from this height to the floor slab can be obtained by measurement. This distance plus the distance from the ground to the laser rangefinder 710 can be used to calculate the distance from the ground to the floor slab, so as to achieve rapid data collection.

[0050] The above description is only one embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered to fall within the protection scope of the present utility model.
