Abstract
Description
Technical Field
[0001] This utility model relates to the field of laboratory testing equipment technology, specifically a novel waterstop size measuring device. Background Technology
[0002] Rubber waterstops are high-performance elastic waterproof materials. If the waterstop thickness is insufficient, it is prone to tearing under joint pressure, leading to sudden leaks. Insufficient protrusion height will reduce the coverage between the embedded waterstop and the concrete, creating a "weak weld" area, which can cause leaks in heavy rain. Furthermore, insufficient protrusion height in back-adhesive waterstops significantly reduces their drainage efficiency. Therefore, the correctness of the waterstop's protrusion height and thickness plays a crucial role in its waterproofing performance.
[0003] In recent years, traditional vernier calipers have been commonly used in laboratories to measure the dimensions of waterstops, typically containing two external measuring jaws. When measuring the waterstop dimensions, the thickness is first measured using the external measuring jaws, and then the convexity and outer arc height are measured using a depth gauge. This method is not only cumbersome, but the small contact area between the depth gauge and the product also introduces measurement errors when the gauge is tilted. Therefore, a device is needed that can simultaneously measure the convexity and thickness of the waterstop under stable baseline conditions. Utility Model Content
[0004] The purpose of this utility model is to provide a new type of waterstop belt size measuring device, which solves the problems of existing measuring methods not only being cumbersome in operation, but also having a small contact area between the depth gauge and the product, which leads to measurement errors when the gauge is tilted.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel waterstop tape size measuring device, comprising a main ruler and a first ruler frame slidably sleeved on the main ruler, a first measuring claw fixedly connected to one end of the main ruler, a second measuring claw fixedly connected to one end of the first ruler frame, a secondary ruler fixedly connected to the second measuring claw, a second ruler frame slidably sleeved on the secondary ruler, a third measuring claw fixedly connected to one end of the second ruler frame, and an extension claw slidably connected to the lower end of the third measuring claw.
[0006] With the above structural design, based on a fixed measurement baseline, the thickness of the waterstop is measured using a main scale, while the convexity is measured using a secondary scale. This improves work efficiency and reduces errors caused by the tilt of the depth gauge. The third measuring claw has an internal cavity and can freely extend and retract via a sliding extension claw, facilitating the measurement of the convexity at different positions of the waterstop.
[0007] Preferably, the secondary ruler has a cylindrical structure, and the second ruler frame has a cylindrical structure.
[0008] Using the above design, the second measuring frame can rotate around the vernier scale. After the first and second measuring claws have measured the thickness of the waterstop, they act as clamping devices. Sliding the second measuring frame moves the third measuring claw to the convex height or the upper surface of the outer arc. The third measuring claw can rotate freely according to the position of the convex height to measure the values at multiple locations.
[0009] Preferably, a first fastening screw is threaded onto the first ruler frame, and the lower end of the first fastening screw abuts against the side wall of the main ruler.
[0010] The above design scheme uses the first fastening screw to fix the first ruler frame and the main ruler relative to each other, which facilitates the measurement of the thickness of the waterstop.
[0011] Preferably, a second fastening screw is threaded onto the second ruler frame, and the lower end of the second fastening screw abuts against the side wall of the auxiliary ruler.
[0012] With the above structural design, the second ruler frame and the auxiliary ruler are fixed relative to each other by the second fastening screw, which facilitates the measurement of the convex height of the waterstop.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] Based on a fixed measurement baseline, the thickness of the waterstop is measured using a main ruler, while the convexity is measured using a secondary ruler. This improves work efficiency and reduces errors caused by the tilt of the depth gauge. The third measuring claw has an internal cavity and can freely extend and retract via a sliding extension claw, facilitating the measurement of the convexity at different positions of the waterstop.

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.
[0019] Please see Figures 1 to 3This utility model provides a technical solution: a novel waterstop tape size measuring device, comprising a main ruler 1 and a first ruler frame 2 slidably fitted on the main ruler 1. The main ruler 1 has graduations on both its front and back surfaces. The first ruler frame 2 is a cuboid with a groove, allowing it to slide on the main ruler 1. Notches are provided on both its front and back surfaces to expose the graduations on the main ruler 1. A first measuring claw 7 is fixedly connected to one end of the main ruler 1. A second measuring claw 8 is fixedly connected to one end of the first ruler frame 2 near the first measuring claw 7. A secondary ruler 3 is fixedly connected to the second measuring claw 8, and the secondary ruler 3 is perpendicular to the second measuring claw 8. A second ruler frame 4 is slidably fitted on the secondary ruler 3. The secondary ruler 3 has graduations on both its front and back surfaces. Notches are provided on both sides of the second ruler frame 4 to expose the graduations on the secondary ruler 3. A third measuring claw 9 is fixedly connected to one end of the second ruler frame 4 near the second measuring claw 8. An extension claw 10 is slidably connected to the lower end of the third measuring claw 9. The third measuring claw 9 has a cavity inside, and can freely extend and retract by sliding the extension claw 10 to extend the length of the third measuring claw 9. The top of the extension claw 10 has a square block to prevent the extension claw 10 from detaching from the cavity when sliding inside the cavity of the third measuring claw 9.
[0020] The secondary ruler 3 has a cylindrical structure, and the second ruler frame 4 has a cylindrical structure.
[0021] The first ruler frame 2 is threaded with a first fastening screw 5, and the lower end of the first fastening screw 5 abuts against the side wall of the main ruler 1.

[0023] Working principle: In use, based on a fixed measuring baseline, the thickness of the waterstop 11 is measured using the main ruler 1. After measuring the thickness of the waterstop 11, the waterstop 11 can be clamped using the first measuring claw 7 and the second measuring claw 8. Simultaneously, the convex height is measured using the auxiliary ruler 3. At this time, the distance between the second measuring claw 8 and the third measuring claw 9 plus the width of the second measuring claw 8 is the height of the convex height of the waterstop 11. The third measuring claw 9 can rotate freely according to the position of the convex height, measuring the values at multiple positions, improving work efficiency and reducing errors caused by the tilt of the depth gauge. The third measuring claw 9 has a cavity inside, which can be freely extended and retracted by the sliding extension claw 10, facilitating the measurement of the convex height of the waterstop 11 at different positions.
