Description

Technical Field

[0001] This utility model belongs to the field of height difference measurement technology at joints, specifically a ruler for measuring height difference at joints between adjacent blocks. Background Technology

[0002] In building decoration projects, the height difference between the joints of adjacent building materials (such as ceramic tiles and marble) is a key parameter affecting both decorative effect and functionality. The "Code for Acceptance of Construction Quality of Building Ground Engineering" (GB 50209-2010) clearly stipulates the allowable deviations for the surface layers of adjacent building materials (such as ceramic tiles and marble). For example, for ceramic tiles, the allowable height difference at the joints of adjacent tiles is specified as ≤0.5mm (ordinary construction) or as per design requirements (high-end decoration). Therefore, it is necessary to measure the height difference between the two materials before the adhesive on the tile base has completely dried.

[0003] However, traditional detection methods such as laser levels and electronic inclinometers can achieve high-precision measurements, but they have problems such as complex equipment and high cost. At the same time, the existing measuring devices are large in size, making it difficult to store the entire device. In order to solve the above problems, this utility model designs a height difference measuring ruler at the joint of adjacent blocks. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a height difference measuring ruler at the joint of adjacent blocks, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a height difference measuring ruler for the joint of adjacent blocks, comprising a ground surface, a left ceramic tile fixed to the top of the ground surface, a right ceramic tile fixedly connected to the ground surface at the right end of the left ceramic tile, a ruler tightly fitted to the top of the left ceramic tile, a measuring groove inside the ruler, a measuring ruler slidably connected inside the measuring groove, a measuring groove on the measuring ruler, a blocking plate tightly fitted to the left end of the ruler, a measuring needle inside the measuring ruler, a moving rod fixed to the right end of the measuring needle, a moving tube slidably connected to the right end of the moving rod, a fixed strip rotatably connected to the moving tube via a rotating shaft, a guide rail fixed to the right end of the ruler, a gravity hammer inside the guide rail, a pin fixed to the bottom of the gravity hammer, positioning strips fixed to the front and rear ends of the measuring ruler, a locking rod slidably connected to each positioning strip, a locking block fixed inside each locking rod, and two sets of locking pits on the ruler.

[0006] Preferably, several stabilizing plates are fixed at both ends of the straightedge, the bottom of each stabilizing plate is tightly fitted to the left ceramic tile, two sets of stabilizing strips are fixed at the outer end of the measuring ruler, each stabilizing strip is slidably connected to the stabilizing groove on the straightedge, each locking block can be tightly fitted to the locking pit on its inner side, each positioning strip is slidably connected to the moving groove on the straightedge, a positioning plate is fixed to the outside of each locking rod, and a locking spring is also provided on the outside of each locking rod.

[0007] Preferably, a positioning block is fixed to the left end of the straightedge, the positioning block is rotatably connected to the blocking plate, a handle is fixed to the left end of the blocking plate, and locking rods are also fixed to the front and rear ends of the straightedge. A locking block is slidably connected to the outside of each locking rod, the two locking blocks are tightly fitted to the blocking plate, and a locking spring is provided on the outside of each locking rod.

[0008] Preferably, the ruler is fixedly connected to the fixing strip at its top, the movable tube is provided with a sliding groove, and the movable rod is fastened to the movable tube by a nut.

[0009] Preferably, the right end of the moving tube is rotatably connected to a positioning buckle via a rotating shaft. The positioning buckle is fixedly connected to the gravity hammer at its bottom. The gravity hammer is slidably connected to the guide rail. Two connecting plates are fixed at the bottom of the guide rail. The right end of the ruler is provided with a locking groove. The connecting plates are fastened to the locking groove by bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention ensures the stability of the entire device through the straightedge, while the locking rod and locking spring work together to keep the locking block tightly against the straightedge, thereby locking the blocking plate and preventing the measuring scale from detaching from the straightedge. This also allows the measuring scale to be detached, reducing the overall size of the device and making it easier to store. Furthermore, the moving rod, measuring needle, and sliding groove allow the measuring needle to move, thus adapting to measuring scales in different positions, thereby increasing the applicability of the entire device and ensuring measurement accuracy.

[0012] This invention uses a measuring groove and a measuring needle to measure the height difference between the magnified left and right ceramic tiles. A guide rail is used for the gravity hammer, whose weight is greater than the sum of the weights of the moving tube and the moving rod. This ensures that the right end of the moving tube is lower than the left end when it is not under force, thus guaranteeing that the pin is in close contact with the right ceramic tile, thereby ensuring measurement accuracy, improving measurement efficiency, and guaranteeing measurement results. At the same time, this device has a simple principle and low material consumption, thus saving costs and resources.

[0013] Each set of locking recesses in this utility model has several, and the distance between each locking recess and the fixed strip is an integer multiple of the distance between the right end of the moving tube and the fixed strip. This makes the left and right ends of the fixed strip form two similar triangles. When the locking block engages with one of the locking recesses, the size indicated by the measuring needle is an integer multiple of the actual size. The locking rod and locking spring work together to make the locking block fit tightly with the locking recess, thereby ensuring the stability of the measuring ruler, improving the measurement range, ensuring measurement accuracy, and thus ensuring the measurement effect.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example 1, by Figures 1-3 , Figures 6-7The present invention includes a ground surface 1, which supports the entire device. A left ceramic tile 101 is fixed to the top of the ground surface 1, and a right ceramic tile 102 is fixedly connected to the ground surface 1 at the right end of the left ceramic tile 101. A straightedge 3, made of alloy material, is tightly fitted to the top of the left ceramic tile 101 to ensure the stability of the entire device. A measuring groove 307 is provided inside the straightedge 3, which provides a moving path for a measuring ruler 2. A measuring ruler 2, made of alloy material, is slidably connected inside the measuring groove 307. The measuring ruler 2 has a measuring groove 201, which, in conjunction with the measuring needle 502, is used to measure the magnified left ceramic tile 101 and right ceramic tile 102. The height difference of 02 is addressed by a baffle plate 4 tightly fitted to the left end of the straightedge 3. The baffle plate 4, made of alloy material, prevents the measuring scale 2 from detaching from the straightedge 3 while allowing for detachment of the measuring scale 2, thus reducing the overall size of the device and facilitating storage. The measuring scale 2 contains a measuring needle 502, also made of alloy material. A moving rod 501, also made of alloy material, is fixed to the right end of the measuring needle 502. A moving tube 5, also made of alloy material, is slidably connected to the right end of the moving rod 501. The moving tube 5, also made of alloy material, works in conjunction with the moving rod 501 to allow the moving rod 501 to move, facilitating the movement of the measuring scale 2 and improving the overall device's efficiency. Within the scope of use, the movable tube 5 is rotatably connected to a fixing strip 503 via a rotating shaft. The fixing strip 503 is made of alloy material and is used to position the movable tube 5. A guide rail 6, also made of alloy material, is fixed to the right end of the ruler 3. The guide rail 6 is used to position the gravity hammer 701. The gravity hammer 701, also made of alloy material, is located inside the guide rail 6. The weight of the gravity hammer 701 is greater than the sum of the weights of the movable tube 5 and the movable rod 501, so that when the movable tube 5 is not under force, the right end is lower than the left end. This ensures that the pin 702 is in close contact with the right ceramic tile 102, thereby ensuring measurement accuracy. A top is fixed to the bottom of the gravity hammer 701. The needle 702, made of alloy material, supports the gravity hammer 701. Positioning strips 203, also made of alloy material, are fixed to the front and rear ends of the measuring scale 2. These strips are used to position the positioning plate 204. A locking rod 205, also made of alloy material, is slidably connected to each positioning strip 203. A locking block 207, also made of alloy material, is fixed to the inner side of each locking rod 205. The ruler 3 also has two sets of locking recesses 305, each set containing several recesses. The distance between each locking recess 305 and the fixing strip 503 is an integer multiple of the distance between the right end of the moving tube 5 and the fixing strip 503.This causes the left and right ends of the fixing strip 503 to form two similar triangles. When the locking block 207 engages with one of the locking recesses 305, the dimension indicated by the measuring needle 502 is an integer multiple of the actual dimension, with the multiple decreasing from left to right. The locking rod 205 and the locking spring 206 cooperate to ensure that the locking block 207 is tightly fitted against the locking recess 305, thereby guaranteeing the stability of the measuring ruler 2.

[0027] Example 2, based on Example 1, combined with... Figures 4-5 , Figure 8The ruler 3 has several stabilizing plates 301 fixed at both ends. These stabilizing plates 301 are made of alloy material and ensure the stability of the entire device. The bottom of each stabilizing plate 301 is tightly fitted to the left ceramic tile 101. Two sets of stabilizing strips 202 are fixed to the outer end of the measuring ruler 2. These stabilizing strips 202 are also made of alloy material and ensure the stability of the measuring ruler 2. Each stabilizing strip 202 is slidably connected to a stabilizing groove 303 on the ruler 3. Each locking block 207 is tightly fitted to its inner locking recess 305. Each positioning strip 203 is slidably connected to a moving groove 304 on the ruler 3. Each locking rod 205 has a fixed external fixing... Positioning plate 204 is used to position the locking spring 206. Each locking rod 205 is also provided with a locking spring 206 on its exterior. The locking spring 206 is elastic, so that the locking block 207 can fit tightly against the locking recess 305, thereby ensuring the stability of the measuring ruler 2. The left end of the guide ruler 3 is fixed with a positioning block 401. The positioning block 401 is made of alloy material and is used to position the blocking plate 4. The positioning block 401 is rotatably connected to the blocking plate 4. The left end of the blocking plate 4 is fixed with a handle 402. The handle 402 is made of alloy material, thereby facilitating the installation of the measuring ruler 2. The front and rear ends of the guide ruler 3 are also fixed with locking rods 404. The locking rods 404 are made of alloy material. Made of alloy material, the locking rod 404 is used to position the locking block 403. Each locking rod 404 is slidably connected to a locking block 403, which is made of alloy material. The locking block 403 is used to position the blocking plate 4, thereby positioning the measuring ruler 2. The two locking blocks 403 are tightly fitted to the blocking plate 4. Each locking rod 404 is provided with a locking spring 405. The locking spring 405 is elastic, so that the locking block 403 is tightly fitted to the ruler 3. The ruler 3 is fixedly connected to the fixing strip 503 at its top. The moving tube 5 is provided with a sliding groove 504, which facilitates the movement of the nut 505. The moving rod 501 is externally connected to the screw... The female part 505 is fastened to the moving tube 5. The right end of the moving tube 5 is rotatably connected to a positioning buckle 7 via a rotating shaft 703. The positioning buckle 7 is made of alloy material and facilitates the rotation of the moving tube 5. The positioning buckle 7 is fixedly connected to the gravity hammer 701 at its bottom. The gravity hammer 701 is slidably connected to the guide rail 6. Two connecting plates 601 are fixed at the bottom of the guide rail 6. The connecting plates 601 are made of alloy material and are used to position the guide rail 6. The right end of the straightedge 3 is provided with a locking groove 302. The locking groove 302 is used to position the guide rail 6, so that the guide rail 6 is perpendicular to the straightedge 3. The connecting plate 601 is fastened to the locking groove 302 by bolts.

[0028] When it is necessary to measure the height difference between the left tile 101 and the right tile 102, the worker assembles the entire device, that is, by fastening the bolts 602 and the locking groove 302, thereby fixing the ruler 3 and the guide rail 6. At this time, the worker installs the positioning buckle 7 inside the guide rail 6 through the rotating shaft 703. Then, the worker pulls the handle 402, thereby opening the blocking plate 4. The worker then places the measuring ruler 2 inside the ruler 3. At this time, due to the cooperation of the stabilizing groove 303 and the stabilizing bar 202, the movement... The groove 304 and the positioning strip 203 cooperate to allow the measuring ruler 2 to move along the guide ruler 3. The operator then closes the blocking plate 4 and pulls the locking block 403 to make the blocking plate 4 and the guide ruler 2 fit tightly together. Simultaneously, the locking block 403 prevents the measuring ruler 2 from slipping out. At this point, the operator places the guide ruler 3 on the left tile 101, and the ejector pin 702 fits tightly against the right tile 102. Due to gravity, the gravity hammer 701 descends, causing the moving tube 5 to tilt upwards, thus allowing the measuring ruler to be moved. The needle 502 and the measuring groove 201 are used to measure the height difference between the left tile 101 and the right tile 102. If the displayed value is too small to measure, the operator pulls the positioning plate 204 to disengage the locking block 207 from the locking recess 305. The operator then moves the measuring ruler 2 to the left, causing the locking block 207 to fit tightly against the larger locking recess 305, thus magnifying the measurement. At this point, the operator can easily move the moving rod 501 using the nut 505 and the sliding groove 504, thus facilitating the movement of the measuring needle 502. Measurements are taken because the distance between each locking recess 305 and the fixing strip 503 is an integer multiple of the distance between the right end of the moving tube 5 and the fixing strip 503. This results in two similar triangles being formed at the left and right ends of the fixing strip 503. Consequently, when the locking block 207 engages with one of the locking recesses 305, the dimension indicated by the measuring needle 502 is an integer multiple of the actual dimension, with the multiple decreasing from left to right. This ensures that when the desired multiple is reached, the bottom right-angled side is magnified by the corresponding multiple, and the vertical side of the similar triangle is also magnified by the corresponding multiple, thus facilitating measurement.

[0029] The working process of this utility model is as follows: When it is necessary to measure the height difference between the left tile 101 and the right tile 102, the worker assembles the entire device, that is, the bolts are used to fasten 602 and the locking groove 302, thereby fixing the ruler 3 and the guide rail 6. At this time, the worker installs the positioning buckle 7 inside the guide rail 6 through the rotating shaft 703. Then, the worker pulls the handle 402, thereby opening the blocking plate 4. The worker then places the measuring ruler 2 inside the ruler 3. At this time, due to the stabilizing groove 303 and the stabilizing bar 2... 02. With the cooperation of the moving groove 304 and the positioning strip 203, the measuring ruler 2 can move along the guide ruler 3. Further, the operator closes the blocking plate 4 and pulls the locking block 403 to make the blocking plate 4 and the guide ruler 2 fit tightly together. Simultaneously, the locking block 403 prevents the measuring ruler 2 from slipping out. At this time, the operator places the guide ruler 3 on the left tile 101. The ejector pin 702 is now in close contact with the right tile 102. Due to gravity, the gravity hammer 701 descends, causing the moving tube 5 to tilt upwards. The height difference between the left tile 101 and the right tile 102 can be measured by the action of the measuring needle 502 and the measuring groove 201. If the displayed value is too small to be measured, the operator pulls the positioning plate 204 to disengage the locking block 207 from the locking recess 305. The operator then moves the measuring ruler 2 to the left, so that the locking block 207 is in close contact with the locking recess 305, which has a larger magnification, thereby increasing the measurement magnification. At this time, the operator can easily move the moving rod 501 by using the nut 505 and the sliding groove 504, thus facilitating the measurement of the measuring needle. 502 measurement: Since the distance between each locking pit 305 and the fixing strip 503 is an integer multiple of the distance between the right end of the moving tube 5 and the fixing strip 503, two similar triangles are formed at the left and right ends of the fixing strip 503. As a result, when the locking block 207 engages with one of the locking pits 305, the size indicated by the measuring needle 502 is an integer multiple of the actual size, with the multiple decreasing from left to right. This ensures that when the desired multiple is reached, the bottom right-angled side is magnified by the corresponding multiple, and the vertical side of the similar triangle is also magnified by the corresponding multiple, thus facilitating measurement.
