Description

Technical Field

[0001] The utility model belongs to the technical field of measuring tools, and in particular relates to a multifunctional measuring ruler. Background Art

[0002] A measuring ruler, as a tool specifically used to measure distance, length, width and other dimensions, has a very wide range of applications, covering many fields such as daily life, industrial production and scientific research.

[0003] During building construction and inspection, traditional measuring rulers are relatively limited in their functionality and can often only meet the measurement needs of a single data point, such as length, angle, or levelness. This limitation forces workers to carry multiple measuring tools to cope with different measurement needs when performing measurement tasks, greatly increasing the complexity and tediousness of the operation. To this end, we proposed a multifunctional measuring ruler to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a multifunctional measuring ruler for solving the problems existing in the background technology.

[0005] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0006] A multifunctional measuring ruler comprises two semicircular rings, which are symmetrically arranged with each other, an upper plate is fixed on the upper side of the inner walls of the two semicircular rings, and the two upper plates are hinged to each other, a lower plate is fixed to the middle part of the inner walls of the two semicircular rings, and the two upper plates correspond to the two lower plates one-to-one, threaded holes are provided in the middle parts of the two upper plates and the two lower plates, the two threaded holes on the upper side and the two threaded holes on the lower side are located in the same vertical plane, a threaded rod is threadedly connected between any threaded hole on the upper side and the corresponding threaded hole on the lower side, a ruler is provided between the upper plate and the lower plate, a sliding groove is provided at the upper end of the ruler, the threaded rod is located inside the sliding groove, and a locking assembly is provided between the two lower plates and the threaded rod.

[0007] The two semicircular arc rings are arranged opposite to each other, and a complete circular ring can be formed by the two upper plates hinged to each other and fixed with the locking assembly. With the help of the scale on the lower side of the inner wall of the circular ring, it is convenient for the staff to measure the angle. After rotating the threaded rod, the ruler can be removed to measure the length. After the threaded rod is rotated into the threaded hole, the threaded rod is located inside the slide groove. In this way, when the two semicircular arc rings are stacked on each other, they can rely on the ruler to naturally droop and then measure the verticality. This eliminates the need for staff to carry multiple measuring tools, thereby improving the operability and convenience of staff.

[0008] It is further defined that the locking assembly includes a card block, which is fixedly connected to one end of any lower plate close to the other lower plate, and a card slot matching the card block is opened at the lower end of the other lower plate, and the threaded hole on the lower side passes through the card slot and the card block.

[0009] It is further defined that a bolt head is fixed to the upper end of the threaded rod, and anti-slip grooves are provided on the outer side of the bolt head.

[0010] It is further defined that a pressure plate is threadedly connected to the outer side of the threaded rod, and the pressure plate abuts against the upper end of the ruler, and anti-slip grooves are provided on the outer side of the pressure plate.

[0011] It is further defined that the outer side of the upper end of the ruler is set to be inclined, and the inclined surface of the ruler is provided with a scale bar.

[0012] It is further defined that calibration slots are provided at both ends of the ruler that are farther apart from each other.

[0013] Beneficial effects of the utility model:

[0014] 1. The symmetrical arrangement and hinged design of the two semicircular rings enable the device to switch freely between stacking and unfolding. This makes it easy to store and carry, and can be unfolded into a complete circle for angle measurement when needed.

[0015] 2. The combination of the threaded rod and the threaded hole, as well as the block and slot design of the locking assembly, makes the fixing and unfolding of the measuring ruler simple and quick, thereby improving work efficiency.

[0016] 3. The measuring ruler integrates multiple measurement functions, including angle measurement, length measurement and verticality measurement, which can meet various measurement needs and reduce the trouble of carrying multiple tools. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0026] Example 1:

[0027] like Figure 1-Figure 3 As shown, a multifunctional measuring ruler includes two semicircular arc rings 100, the two semicircular arc rings 100 are symmetrically arranged, an upper plate 101 is fixed on the upper side of the inner wall of the two semicircular arc rings 100, and the two upper plates 101 are hinged to each other, a lower plate 102 is fixed in the middle of the inner wall of the two semicircular arc rings 100, and the two upper plates 101 correspond to the two lower plates 102 one by one, and the middle of the two upper plates 101 and the two lower plates 102 are opened. The threaded holes 103, the two threaded holes 103 on the upper side and the two threaded holes 103 on the lower side are located in the same vertical plane, and a threaded rod 104 is threadedly connected between any threaded hole 103 on the upper side and the corresponding threaded hole 103 on the lower side. A ruler 105 is provided between the upper plate 101 and the lower plate 102, and a slide groove 106 is provided at the upper end of the ruler 105. The threaded rod 104 is located inside the slide groove 106, and a locking assembly is provided between the two lower plates 102 and the threaded rod 104.

[0028] The two upper plates 101 hinged to each other allow the entire measuring ruler to have two forms: stacked and unfolded. The locking assembly can play a fixing role when the two semicircular arc rings 100 are stacked or unfolded. The two unfolded semicircular arc rings 100 can be used to measure angles. The upper plate 101 and the lower plate 102 can not only make it convenient for staff to take the measuring ruler, but also place the ruler 105. When the threaded rod 104 is disengaged from the threaded hole 103, the staff can take out the ruler 105 to measure the length. When the ruler 105 is hung on the outside of the threaded rod 104 by the slide groove 106, the verticality can be measured with the natural droop of the ruler 105.

[0029] In the storage state: the two semicircular arc rings 100 are stacked together, and the threaded rod 104 is inserted into the threaded hole 103 to fix the shape of the entire measuring ruler. This not only reduces the volume of the entire measuring ruler, making it easier to store or carry, but also allows the ruler 105 to hang naturally for verticality measurement.

[0030] In the unfolded state: the two semicircular arc rings 100 are hinged and aligned between the two upper plates 101 to form a complete circular ring. The threaded rod 104 cooperates with the locking assembly to fix the entire unfolded state, which is convenient for subsequent staff to measure the angle. When the threaded rod 104 is removed, the ruler 105 can also be taken out so that the length can be measured.

[0031] Among them, a scale is set on the inner side of the upper end of the ring, so that after stacking, it can not only protect the scale from being worn and affecting the reading of data, but also protect the scale from being damaged by collision when unfolding.

[0032] In this embodiment, by transforming the shapes of the two semicircular arc rings 100, it is not only convenient for the staff to store or carry the measuring ruler, but also the semicircular arc rings 100 can be used to measure angles, the ruler 105 can be used to measure lengths, and the threaded rod 104 can be used in conjunction with the ruler 105 to measure verticality, thereby avoiding the staff from carrying multiple tools and making the measurement work of the staff simpler and easier.

[0033] The working principle of this embodiment is as follows:

[0034] Example 2:

[0035] like Figure 3-5As shown, based on the first embodiment, other components on a multifunctional measuring ruler are further described. The locking assembly includes a clamping block 200, which is fixedly connected to one end of any lower plate 102 close to the other lower plate 102. A clamping slot 201 matching the clamping block 200 is provided at the lower end of the other lower plate 102, and a threaded hole 103 on the lower side passes through the clamping slot 201 and the clamping block 200.

[0036] A bolt head 202 is fixed to the upper end of the threaded rod 104 , and anti-slip grooves are provided on the outer side of the bolt head 202 .

[0037] The outer side of the threaded rod 104 is threadedly connected to a pressure plate 203 , and the pressure plate 203 abuts against the upper end of the ruler 105 , and the outer side of the pressure plate 203 is provided with anti-slip grooves.

[0038] The outer side of the upper end of the ruler 105 is set to be inclined, and the inclined surface of the ruler 105 is provided with a scale bar.

[0039] Calibration slots 204 are formed at both ends of the ruler 105 that are farther apart from each other.

[0040] In this embodiment, when in the unfolded state, the clamping block 200 will be clamped into the clamping slot 201. At this time, when the threaded rod 104 rotates into the threaded hole 103, it will also pass through the clamping slot 201 and the threaded hole 103 on the clamping block 200. In this way, the unfolded measuring ruler can be shaped, thereby facilitating subsequent measurements.

[0041] The anti-slip grooves of the bolt head 202 can increase the friction with the user's hand, making it convenient for the user to quickly twist the bolt head 202. The rotation of the bolt head 202 can drive the threaded rod 104 to disengage from or enter the threaded hole 103, making it convenient to quickly shape the deformed postures of the two semicircular arc rings 100.

[0042] The pressure plate 203 can cooperate with the upper plate 101 or the lower plate 102 to clamp and fix the ruler 105. This not only makes it convenient to place and store the ruler 105, but also allows the ruler 105 to droop naturally with the support of the threaded rod 104 when the pressure plate 203 is released, thereby facilitating the measurement of verticality.

[0043] The ruler 105 can measure the length of a building, and the measurement data can be observed more accurately by relying on the scale on the inclined surface of the ruler 105.

[0044] The calibration groove 204 can better align with the vertical line drawn by the staff when measuring verticality.

[0045] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
