Description

Technical Field

[0001] The utility model relates to the technical field of engineering cost, in particular to an engineering cost marking tape measure which is convenient for single-handed operation. Background Art

[0002] The tape measure is a commonly used measuring tool on construction sites. When it is necessary to mark the measured object, a construction cost marking tape measure that is easy to operate with one hand is needed.

[0003] The Chinese patent (CN216845932U) is a marking tape measure for engineering cost. The movable rod drives the push rod to move, and the push rod finally drives two movable plates to move back to each other. The two movable plates drive the marking pen to move back to each other to finally complete the equidistant marking of the tape measure, thereby effectively improving the use effect of the tape measure. At the same time, the equidistant marking makes the positioning of the position to be marked more accurate, and the equidistant marking operation can be achieved without moving the tape measure multiple times, making the equidistant marking operation of the tape measure more convenient.

[0004] However, in actual use, when the above structure is used for marking operation, the movable rod is moved backward, thereby driving the two movable plates to move relatively apart, and at the same time driving the marking pen to move. However, when the marking pen needs to be used for marking operation, the user needs to repeatedly push the movable rod to mark the line, which is cumbersome to operate and reduces the efficiency of use in disguise.

DETAILED DESCRIPTION

[0027] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] See also Figure 1 and Figure 8As shown, a construction cost marking tape measure that is easy to operate with one hand includes a shell 1, a steel coil 2 arranged in the shell 1, and a marking mechanism 3 used in conjunction with the steel coil 2; the marking mechanism 3 includes a clamping plate 31 and a sliding seat 32 for driving the clamping plate 31 to move, and a first connecting plate 33 for installing the sliding seat 32, the construction cost marking tape measure also includes a second connecting plate 34 and a mounting mechanism 4 for adjusting the distance between the second connecting plate 34 and the first connecting plate 33, the clamping plate 31 is rotatably arranged on the sliding seat 32 and has a pair of openings of the pair of clamping plates 31 facing each other to form a stable clamping space, the inner wall of the clamping plate 31 is provided with a plurality of anti-slip blocks, the anti-slip blocks are semicircular in shape, and the anti-slip blocks are made of rubber, which not only has good anti-slip performance, but also can effectively reduce the friction between the marking pen and the clamping plate 31, thereby extending the service life of the marking pen, and the marking pen can be placed on the pair of clamping plates 31 to prevent the marking pen from falling when marking.

[0029] The marking pen is placed between a pair of clamping plates 31, and the clamping plates 31 can clamp and fix the marking pen to prevent it from falling during use. The first connecting plate 33 and the second connecting plate 34 are provided to facilitate the adjustment of the position of the marking pen along the steel coil 2, so that the marking position can be adjusted and marking pens of different sizes can be clamped and fixed. The user does not need to continuously press the marking mechanism 3, thereby freeing the user's hand operation and making the subsequent marking operation easier. This convenience not only improves work efficiency, but also reduces the user's operating difficulty, making the marking work simpler and more efficient.

[0030] See also Figure 3 and Figure 5 As shown, the marking mechanism 3 also includes a telescopic spring 35; the telescopic spring 35 is arranged on the top, and the two ends of the telescopic spring 35 are respectively fixed to one end of the clamping plate 31, and a travel groove for the clamping plate 31 to rotate is opened on the sliding seat 32, and the telescopic spring 35 is located in the travel groove.

[0031] When the sliding seat 32 drives the clamping plate 31 to mark, the telescopic spring 35 drives the clamping plate 31 to clamp relatively close, so that the user can appropriately telescope according to the marking requirements, thereby maintaining the stable contact between the clamping plate 31 and the marking pen. At the same time, the marking pen can achieve horizontal and stable sliding in the stroke groove, ensuring the continuity and stability of the marking process.

[0032] See also Figure 3 and Figure 5As shown, the mounting mechanism 4 includes a rack 41 and a rotating rod 42; the rack 41 is arranged at one end of the first connecting plate 33; the rotating rod 42 is rotatably arranged in the second connecting plate 34 and is located above the rack 41, and the rotating rod 42 is arranged in the second connecting plate 34 through a damping sleeve, and the function of the damping sleeve is to prevent the rotating rod from rotating freely, thereby ensuring its stability and controllability during operation. In addition, a groove or clamping structure that matches the outer wall diameter of the steel coil 2 is designed between the first connecting plate 33 and the second connecting plate 34, so that the entire marking mechanism can be closely attached to the outer wall of the steel coil, ensuring stability and accuracy during the marking process.

[0033] By rotating the rotating rod 42, the spacing between the first connecting plate 33 and the second connecting plate 34 can be conveniently adjusted. When the rotating rod 42 rotates, the first connecting plate 33 moves along the rack 41 and approaches the second connecting plate 34 relatively until the outer wall of the steel coil 2 is clamped, ensuring the accuracy and stability of the marking position, and also allowing the entire adjustment process to be completed with one hand, greatly improving the convenience of operation. During the marking process, the clamping mechanism 3 can effectively prevent displacement between the first connecting plate 33 and the second connecting plate 34, thereby ensuring high precision and stability of marking, freeing the user's hands, so that they can focus more on the marking work.

[0034] See also Figure 5 and Figure 6 As shown, the mounting mechanism 4 also includes a gear 43 and a limiting block 44; the gear 43 is arranged outside the rotating rod 42 and meshes with the rack 41; the limiting block is arranged at one end of the first connecting plate 33 and slides with the second connecting plate 34. The shape of the limiting block 44 is varied, and can be round or square, etc., but considering the requirements of stability and sliding fit, the square shape is preferred. A limiting groove that matches the limiting block 44 is provided on the second connecting plate 34 to ensure a tight and smooth sliding fit between the two. The main function of the limiting block 44 is to limit and stabilize the sliding of the second connecting plate 34, so that it can remain stable when sliding along the rack 41 and the limiting block 44.

[0035] When the rotating rod 42 rotates, the gear 43 provided outside the rotating rod 42 can be driven to rotate synchronously, so that the gear 43 and the rack 41 are engaged, and the second connecting plate 34 is driven to move horizontally along the rack 41 away from the first connecting plate 33. At this time, the distance between the first connecting plate 33 and the second connecting plate 34 can be adjusted.

[0036] See also Figure 6 and Figure 7As shown, the engineering cost marking tape also includes a scraping mechanism 5 for cleaning the steel coil 2; the scraping mechanism 5 includes a first mounting block 51 and a second mounting block 52; the first mounting block 51 is arranged on the shell 1 and is located above the steel coil 2; the second mounting block 52 is arranged on the shell 1 and is located below the steel coil 2.

[0037] The first mounting block 51 and the second mounting block 52 are arranged at the extended position of the steel coil 2 , and the first mounting block 51 and the second mounting block 52 are used to block dust and gravel from falling into the gap between the housing 1 and the extended position of the steel coil 2 .

[0038] See also Figure 6 and Figure 7 As shown, the scraping mechanism 5 further includes a first scraper 53 and a second scraper 54; the first scraper 53 is arranged on the first mounting block 51 and close to the top of the steel coil 2; the second scraper 54 is arranged above the second mounting block 52 and close to the bottom of the steel coil 2. The first scraper 53 and the second scraper 54 are arc-shaped to fit the outer wall of the steel coil 2 more closely, so that the scrapers can fit more closely to the outer wall of the steel coil 2, thereby more effectively scraping off dirt or impurities on the surface of the steel coil 2. This fit not only improves the scraping effect, but also reduces damage to the outer wall of the steel coil 2, thereby extending the service life of the steel coil 2.

[0039] When the steel coil 2 is retracted into the shell 1, the first scraper 53 and the second scraper 54 scrape off dust and dirt from the outer wall of the steel coil 2, so that each time the steel coil 2 is used for measurement, the outer wall of the steel coil 2 can be scraped and cleaned, so that the steel coil 2 is always kept clean, thereby increasing the service life of the steel coil 2 in disguise.

[0040] See also Figure 1 and Figure 7 As shown, the scraping mechanism 5 also includes a first limiting roller 55 and a second limiting roller 56; the first limiting roller 55 is arranged in the shell body 1 and close to the side of the first scraper 53; the second limiting roller 56 is arranged in the shell body 1 and is located below the first limiting rod. The first limiting roller 55 is in the shape of a cylinder, with narrow diameters on both sides and gradually widening diameter in the middle, while the second limiting roller 56 is in the opposite shape, with wider diameters on both sides and narrower diameter in the middle. The first limiting roller 55 and the second limiting roller 56 are both located on the same vertical straight line.

[0041] When the steel coil 2 is received into the housing 1 , the steel coil 2 is rolled and reset under the rolling restriction of the first limiting roller 55 and the second limiting roller 56 , so as to prevent the steel coil 2 from bending due to long-term use and improve the service life of the steel coil 2 .

[0042] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
