Description

Technical Field

[0001] This utility model relates to the field of distance measurement technology, specifically a step gauge for measuring step height and gap width. Background Technology

[0002] A gap gauge is a precision measuring tool used to accurately measure the height of steps, the width of gaps, planar differences, or minute dimensional variations on the surface of an object. It is widely used in machinery manufacturing, precision machining, construction engineering, and electronic assembly. Its core functions include checking the machining accuracy of parts (such as whether the step height of mating surfaces in mechanical parts meets design standards to ensure no interference or excessive gaps during assembly), inspecting gap uniformity (in construction or decoration projects, measuring the gap width between tiles, stone, and slabs to ensure construction quality and aesthetics), and controlling micro-dimensions (in precision manufacturing such as electronic chip and mold processing, measuring the dimensions of minute steps or gaps to ensure product performance meets standards). Through contact measurement combined with a scale / indicator, it can achieve high-precision dimensional inspection and is an important tool for quality control and process adjustment.

[0003] Conventional stair gap gauges can detect some low-height steps and gaps, but they cannot measure some larger stair gaps. For example, in some low-rise residential buildings without fire protection facilities, there are gaps between the stairs in the stairwell. These gaps are specifically designed for fire pipes. When testing whether these gaps meet the standards, existing conventional stair gap gauges cannot detect them because these gaps exceed the maximum detection value. At the same time, stair gap gauges are too expensive. Therefore, a stair gap gauge with a simple structure that can be compatible with large-scale gaps is needed. Utility Model Content

[0004] The purpose of this invention is to provide a step gauge for measuring step height and gap width, in order to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a step gauge for measuring step height and gap width, comprising a housing, two measuring plates are arranged inside the housing, a measuring rod is rotatably connected to the outer surface of the measuring plate, an electric rod and an electric base are arranged above the measuring plate, and a scale is arranged above the measuring plate.

[0006] Preferably, a slide rod is fixedly installed on the inner side wall of the outer shell, the outer surface of the slide rod is slidably connected to the inner wall of the distance measuring plate, and a spring is sleeved on the outer surface of the slide rod, with the two ends of the spring respectively fixedly installed on the sides of the two distance measuring plates.

[0007] Preferably, a mechanism strip is installed on the outer surface of each of the two distance measuring plates, and the outer surface of the mechanism strip is slidably connected to the outer surface of the other distance measuring plate. A wheel frame is fixedly installed on the inner bottom wall of the housing, and a gear is installed inside the wheel frame. The outer surface of the gear meshes with the outer surface of the mechanism strip.

[0008] Preferably, the pole is fixedly installed on the inner surface of the housing, the base is fixedly installed on the outer surface of one of the distance measuring plates, and the inner wall of the base is slidably connected to the outer surface of the pole.

[0010] Preferably, a handle is fixedly installed on the outer surface of the housing, and a reset rod is fixedly installed on the outer surface of one of the distance measuring plates. A groove is formed on the outer surface of the housing on the outer surface of the reset rod, and the reset rod slides in a directional manner through the groove.

[0011] Preferably, three fixing seats are fixedly installed on the outer surface of one of the ranging plates, and I-shaped grooves are opened on the inner side of the fixing seats.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application utilizes the cooperation of a distance measuring plate, a distance measuring rod, a power pole, a power base, and a ruler. When it is necessary to detect the height of a step, the distance measuring plate is placed against the step, and then the ruler is lowered until it reaches the next step. The height can be calculated by measuring the distance between the distance measuring plate and the ruler. When it is necessary to detect the width of a stair gap, two distance measuring plates can be placed on the gap, and then the distance measuring rod is rotated and lowered. The distance measuring plate will drive the distance measuring rod to move to the left and right sides. When the distance measuring rod is blocked by the sides of the stairs on both sides of the gap, the distance between the two distance measuring rods can be calculated by measuring the power pole and the power base, thereby calculating the distance of the gap. This device can accommodate large-scale gaps, and its simple structure and low cost solve the problem that existing conventional step gap detection methods cannot detect gaps that exceed the maximum detection value.

[0014] 2. This application utilizes the cooperation between the machine bar, gear, and distance measuring plate to ensure that when one distance measuring plate starts to move, the distance measuring plate can drive the other machine bar and distance measuring plate to move through the machine bar and gear, thereby ensuring that the two distance measuring plates move in completely opposite directions and at the same distance and speed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figures 1-5As shown, this utility model provides a technical solution for measuring step height and gap width using a step gauge. It includes a housing 1, inside which are two measuring plates 2. A measuring rod 3 is rotatably connected to the outer surface of each measuring plate 2. An electric rod 4 and an electric base 5 are located above the measuring plates 2. A scale 6 is located above the measuring plates 2. When step height needs to be measured, the measuring plates 2 are placed against the step, and then the scale 6 is lowered until it reaches the next step. The height can then be calculated by the distance between the measuring plates 2 and the scale 6. When it is necessary to detect the width of a stair gap, two measuring plates 2 can be placed on the gap, and then the measuring rod 3 can be rotated and lowered. The measuring plates 2 will drive the measuring rod 3 to move to the left and right sides. When the measuring rod 3 is blocked by the sides of the stairs on both sides of the gap, the distance between the two measuring rods 3 can be calculated by the electric pole 4 and the electric base 5, and thus the distance of the gap can be calculated. This device can be compatible with large-scale gaps, and at the same time, it has a simple structure and low cost, solving the problem that existing conventional step gap rules cannot detect gaps that exceed the maximum detection value.

[0023] A slide rod 7 is fixedly installed on the inner wall of the outer casing 1. The outer surface of the slide rod 7 is slidably connected to the inner wall of the distance measuring plate 2. A spring 8 is sleeved on the outer surface of the slide rod 7. The two ends of the spring 8 are fixedly installed on the sides of the two distance measuring plates 2 respectively. The spring 8 can always push the distance measuring plate 2, forcing the distance measuring plate 2 to move on the slide rod 7, and ensuring that the distance measuring plate 2 maintains the farthest interval distance when there are no other external forces.

[0024] Each of the two rangefinder plates 2 has a mechanism 10 mounted on its outer surface. The outer surface of the mechanism 10 is slidably connected to the outer surface of the other rangefinder plate 2. A wheel frame 11 is fixedly mounted on the inner bottom wall of the outer casing 1. A gear 12 is installed inside the wheel frame 11. The outer surface of the gear 12 meshes with the outer surface of the mechanism 10. When one of the rangefinder plates 2 starts to move, the rangefinder plate 2 can drive the other mechanism 10 and the rangefinder plate 2 to move through the mechanism 10 and the gear 12, thereby ensuring that the two rangefinder plates 2 move in completely opposite directions and at the same distance and speed.

[0025] The pole 4 is fixedly installed on the inner surface of the housing 1, and the base 5 is fixedly installed on the outer surface of one of the distance measuring plates 2. The inner wall of the base 5 is slidably connected to the outer surface of the pole 4. A constant voltage is connected inside the pole 4. The base 5 and the pole 4 form a simple sliding rheostat. When the pole 4 moves, the voltage inside the base 5 will increase or decrease, so that the distance between the two distance measuring plates 2 can be calculated by the voltage value.

[0026] Four wheel seats 13 are fixedly installed on the outer surface of the distance measuring plate 2. The outer surface of the wheel seats 13 is rotatably connected to the directional wheels 14. The inner surface of the outer shell 1 is fixedly installed with a slide 15. The outer surface of the directional wheels 14 and the outer surface of the slide 15 are slidably connected. When the distance measuring plate 2 moves, it can move on the slide 15 through the directional wheels 14. The directional wheels 14 and the slide 15 are coordinated by the slide rod 7 to ensure that the distance measuring plate 2 will not tilt when it moves.

[0027] A handle 16 is fixedly installed on the outer surface of the housing 1, and a reset rod 17 is fixedly installed on the outer surface of one of the measuring plates 2. A groove is opened on the outer surface of the housing 1 on the reset rod 17. The reset rod 17 slides in a direction through the groove. When detecting gaps, the handle 16 can be held to bear the weight of the entire device. Then the reset rod 17 can be pulled. When the reset rod 17 is close to the handle 16, it will drive the measuring plate 2, so that the two measuring plates 2 are close to each other. After releasing the reset rod 17, the spring 8 can push the two measuring plates 2 back apart.

[0028] Three mounting bases 9 are fixedly installed on the outer surface of one of the distance measuring plates 2. The inner side of the mounting base 9 is provided with an I-shaped groove. The outer surface of the scale 6 is slidably connected to the inner wall of the mounting base 9 through the I-shaped groove. The mounting base 9 can provide fixation and detection for the scale 6. One of the mounting bases 9, which is away from the handle 16, is transparent and has a red bottom surface, so that the red bottom surface can be directly observed to align with the value on the scale 6.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
