Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of measuring tools, specifically to a new type of edge ruler and stair tread measuring ruler that can be quickly changed. Background Technology
[0002] Stairs are a common architectural design feature with wide applications. Stair treads, as both functional and decorative materials, have strict requirements regarding their dimensions.
[0003] Currently, there are few measuring rulers specifically designed for stair tread dimensions. Construction workers cannot measure accurately, which can easily lead to the accumulation of measurement errors and result in stair treads being either too large or too small.
[0004] Currently, measuring rulers specifically designed for stair treads have appeared on the market. Their structure involves connecting the ruler to the edge through bolts via a connecting seat or connecting rod. In actual use, if the connecting seat or connecting rod needs to be disassembled from the edge ruler, the bolts need to be completely removed. This significantly reduces work efficiency when performing a large number of measurements. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model aims to provide a novel edge ruler and stair tread measuring ruler that can be quickly replaced. By forming an "exit structure" through the interconnected first and second slots on the edge ruler body, the bolts on the connecting seat or connecting rod only need to be loosened slightly to move along the first slot to the second slot, and finally exit the edge ruler through the second slot. This achieves the separation of the connecting seat or connecting rod from the edge ruler without completely disassembling the bolts.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A novel edge ruler that enables quick replacement includes an edge ruler body, wherein the edge ruler body has a first slot and a second slot, one end of the second slot is connected to the first slot; wherein a component can move along the first slot, or the component moves to the connection between the first slot and the second slot and then enters the second slot, moves along the second slot to its other end and then exits the edge ruler body.
[0008] It should be noted that the first slot is formed along the length of the ruler body.
[0009] It should be noted that the second slot and the first slot are perpendicular to each other.
[0010] It should be noted that the component enters through the other end of the second slot, moves along the second slot to the communication point, and then enters the first slot. The component can move along the first slot and be fixed at any position in the first slot.
[0011] Based on the above-described edge ruler structure, this utility model also provides a stair measuring ruler with a novel edge ruler that can be quickly changed. The component is connected to the first slot by bolts. When the bolts are tightened, the component can be fixed at any position in the first slot. When the bolts are loosened, the component can move along the first slot, or the component can move to the connecting point and enter the second slot, and exit the edge ruler body through the other end of the second slot.
[0012] It should be noted that the component may be a connecting seat or a connecting rod.
[0013] It should be noted that the width of the first slot and the second slot is slightly larger than the outer diameter of the bolt.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. The method of separating the connecting seat or connecting rod from the edge ruler is more direct and simple. There is no need to completely remove the bolts of the connecting seat or connecting rod. Just loosen the bolts slightly.
[0016] 2. The installation of the connecting seat or connecting rod with the edge ruler is also simplified. In the prior art, when the connecting seat or connecting rod is connected to the edge ruler, the bolt needs to pass through the edge ruler and the connecting seat (connecting rod) at the same time. With the edge ruler structure of this utility model, the bolt can be directly connected to the connecting seat or connecting rod. After the bolt enters the first slot through the second slot on the edge ruler, it can be moved to any position in the first slot and then the bolt can be tightened.
[0017] 3. The grooved structure of the ruler in this utility model reduces the difficulty of replacing the connecting seat or connecting rod with the ruler, making it convenient for users to replace rulers of different lengths or sizes, thus improving work efficiency. Attached Figure Description

[0019] Figure 2 This is a schematic diagram of the structure of the ruler body and the connecting seat of this utility model;
[0020] Figure 3 This is a schematic diagram of the structure of the ruler body and connecting rod of this utility model. Detailed Implementation
[0021] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.
[0022] like Figure 1 As shown, this utility model is a novel edge ruler that can be quickly changed, including an edge ruler body 1. The edge ruler body 1 is provided with a first slot 2 and a second slot 3. One end of the second slot 3 is connected to the first slot 2. A component can move along the first slot 2, or the component can move to the connection 4 between the first slot 2 and the second slot 3 and then enter the second slot 3, and move along the second slot 3 to its other end and then exit the edge ruler body 1.
[0023] It should be noted that the first slot of this utility model has a guiding function, and the connecting seat or connecting rod connected thereto can move (slide) along the first slot and be fixed at any position in the first slot; while the second slot of this utility model is an exit slot, which allows the connecting seat or connecting rod to be quickly exited or quickly installed in the first slot.
[0024] Furthermore, such as Figure 1 As shown, the first slot 2 of this utility model is opened along the length direction of the ruler body 1.
[0025] Furthermore, such as Figure 1 As shown, the second slot 3 of this utility model is perpendicular to the first slot 1.
[0026] As a preferred technical solution, the aforementioned arrangement of the second slot perpendicular to the first slot is only one possible arrangement. In practical applications, the second slot and the first slot can also be arranged at an angle.
[0027] Furthermore, such as Figure 1 As shown, the component of this utility model enters through the other end of the second slot 3, moves along the second slot 3 to the connecting point 4, and then enters the first slot 2. The component can move along the first slot 2 and be fixed at any position in the first slot 2.
[0028] like Figure 2 , Figure 3As shown, as an application of this utility model, this utility model also provides a stair measuring ruler with a novel edge ruler that can be quickly changed. The component is connected to the first slot 2 by bolts 5. When the bolts 5 are tightened, the component can be fixed at any position in the first slot 2. When the bolts 5 are loosened, the component can move along the first slot 2, or the component can move to the connecting part 4 and enter the second slot 3, and exit the edge ruler body 1 through the other end of the second slot 3.
[0029] Furthermore, such as Figure 2 , Figure 3 As shown, the component of this utility model can be a connecting seat 6 or a connecting rod 7. However, the component can also be other components of a prior art stair measuring ruler that are connected to the edge ruler. The claims and description of this utility model are only illustrative of the component using the connecting seat or connecting rod, and are not intended to limit the structure of the component.
[0030] Furthermore, the width of the first slot and the second slot is slightly larger than the outer diameter of the bolt.
[0031] Example
[0032] When separating the connecting seat or connecting rod of the stair measuring ruler from the edge ruler, slightly loosen the bolts on the connecting seat or connecting rod to allow it to move along the first slot on the edge ruler. Then, move the connecting seat or connecting rod along the first slot until it connects with the second slot. Continue moving the connecting seat or connecting rod along the second slot until it separates from the edge ruler. This completes the separation of the connecting seat or connecting rod. This edge ruler structure eliminates the need to completely disassemble the bolts from the connecting seat or connecting rod, greatly simplifying the replacement process and improving work efficiency.
[0033] If the connecting seat or connecting rod is to be installed with the edge ruler, the bolt can be directly connected to the connecting seat or connecting rod. Then, the bolt is moved from the second slot into the first slot and moved to any position in the first slot before being tightened. This completes the fixed connection between the connecting seat or connecting rod and the edge ruler.
[0034] For those skilled in the art, various corresponding changes and modifications can be made based on the above technical solutions and concepts, and all such changes and modifications should be included within the protection scope of the claims of this utility model.
