Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, and in particular to an expandable quick-folding measuring device. Background Technology

[0002] A measuring tape is a tool used to measure length. Measuring tapes are usually made of soft materials such as fiber, plastic, or leather, which can be bent and folded for easy carrying and use. Measuring tapes are generally long enough to meet different measurement needs. This makes them very useful for measuring large objects or distances, such as measuring the length, width, and height of a room, or measuring the area of ​​land.

[0003] When a measuring tape is unfolded, the unfolded belt easily attracts dust when it rubs against the ground. The dust and impurities adhering to the belt can easily enter the measuring tape when the belt is retracted. In order to clean the dust on the measuring tape, this application proposes an expandable quick-folding measuring device. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the prior art that when a measuring tape is unfolded, the unfolded tape easily attracts dust when rubbing against the ground, and the dust and impurities adhering to the tape easily enter the measuring tape when the tape is retracted. This invention proposes an expandable, quick-folding measuring device.

[0005] The technical solution of this utility model is as follows: An expandable quick-folding measuring device includes a housing and a measuring tape. An outer plate is fixedly connected to the housing. The outer plate has a rectangular limiting hole and a limiting circular hole. A cleaning mechanism is provided on the housing. The cleaning mechanism includes a fixed plate connected to the outer plate. A set of locking blocks is provided on the fixed plate. The two locking blocks are locked onto the rectangular limiting hole. A first scraper and a second scraper for scraping off impurities adhering to the surface of the measuring tape are movably installed on the fixed plate. A first horizontal axis and a second horizontal axis are fixedly connected to the fixed plate. The first horizontal axis and a first cleaning cotton are movably sleeved on the limiting circular hole. The first horizontal axis and the second horizontal axis movably pass through the first cleaning cotton and the second cleaning cotton for cleaning water stains on the surface of the measuring tape.

[0006] Optionally, a first limiting post is movably inserted through the fixed plate, and one end of the first limiting post is connected to the first scraper.

[0007] Optionally, a second limiting post is movably inserted through the fixed plate. One end of the second limiting post is connected to the second scraper. A compression spring is sleeved on the outer circumferential surface of the second scraper. One end of the compression spring contacts the second scraper, and the other end of the compression spring contacts the fixed plate.

[0008] Optionally, a connecting plate is fixedly connected to the housing, and a round hole is provided on the connecting plate.

[0009] Optionally, a third horizontal axis is movably inserted through the housing, a measuring tape is coiled around the measuring tape, and a connector is fixedly connected to one end of the measuring tape.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. The first and second scrapers clean the tape measure stored inside the housing by scraping it, preventing sticky substances from adhering to the tape measure and entering the housing. This cleans the tape measure and improves its usability. At the same time, the first scraper is under the action of gravity, and the second scraper is under the action of the compression spring, which creates a certain squeezing force between the first and second scrapers. The magnitude of the squeezing force is generated by the weight of the first scraper, which can avoid the first and second scrapers from having too much impact on the opening and closing of the tape measure.

[0014] 2. The first and second cleaning cotton are used to clean the tape measure inside the housing, preventing water stains from being absorbed by the tape measure and entering the housing during rainy days. This effectively cleans the tape measure and improves its performance. Furthermore, the entire cleaning mechanism can be disassembled for cleaning, further enhancing the cleaning effect on the tape measure. Attached Figure Description
