Description

Technical Field

[0001] The utility model relates to the technical field of building inspection rulers, in particular to a building inspection ruler for building engineering inspection. Background Art

[0002] In the field of building engineering, ensuring the project quality is of crucial importance. The quality of building engineering is not only related to the safety, durability and service function of buildings, but also directly affects people's life and property safety and the stable development of society. In order to ensure the quality of building engineering, strict quality inspections are required during the construction process and after completion. As a commonly used inspection tool, the building inspection ruler plays an important role in the quality inspection of building engineering. With the continuous progress of building technology, modern building engineering has higher and higher requirements for quality. For example, in projects such as high-rise buildings, large bridges, and precision industrial factories, extremely high precision requirements are imposed on parameters such as the flatness, perpendicularity, and levelness of the structure. If these parameters do not meet the design requirements, it may affect the overall stability and service function of the building. At the same time, the application of some new building materials and construction techniques also requires more accurate inspection means to evaluate their quality effects.

[0003] The prior art such as the utility model with the publication number of CN220556298U discloses an inspection ruler for building engineering. The patent uses an inspection ruler body, and scales are displayed at the front end of the inspection ruler body. The inspection ruler body is composed of a first side ruler, a first middle ruler, a second middle ruler, and a second side ruler connected in sequence. The first middle ruler and the second middle ruler are horizontally and rotatably hinged, and the first middle ruler and the first side ruler, and the second middle ruler and the second side ruler are vertically and rotatably hinged in sequence. Side fixing inserts and middle fixing inserts are provided at the top of the inspection ruler body to connect the first middle ruler, the first side ruler, the second middle ruler, and the second side ruler to form a straight line. This application effectively reduces the space occupied in the length direction when the building engineering inspection straight ruler is carried, improves the portability of the building engineering inspection straight ruler for outdoor carrying and use, and solves the problem that the commonly used straight ruler has a fixed length and cannot be made very long for carrying for size measurement. When measuring longer sizes, a tape measure is generally used. Although the tape measure is convenient to carry, due to its flexible nature, there is a certain elastic deformation when measuring height dimensions from bottom to top, and the measurement accuracy is not precise enough.

[0004] During the process of using an inspection ruler for inspection in daily life, there is a problem that the existing inspection rulers are usually of a fixed length, relatively long in size, and not very convenient to carry. Especially when it is necessary to conduct inspections at multiple different construction sites, the non-retractable inspection ruler is not easy for inspection personnel to carry with them or store, taking up a lot of storage space and causing inconvenience to the movement of inspection personnel. Content of the Utility Model

[0005] The purpose of the present utility model is to solve the disadvantages existing in the prior art, such as being relatively long in size, not very convenient to carry, especially when it is necessary to conduct inspections at multiple different construction sites. The inspection ruler that cannot be telescoped is not easy for the inspectors to carry with them or store, takes up a lot of storage space, and causes inconvenience to the inspectors' actions. Therefore, a building inspection ruler for construction engineering inspection is proposed.

[0006] In order to achieve the above purpose, the present utility model adopts the following technical solutions: A building inspection ruler for construction engineering inspection includes a first measuring ruler, a second measuring ruler, and a telescopic device. The second measuring ruler is arranged on the surface of the first measuring ruler. The third measuring ruler is arranged on the surface of the second measuring ruler. The telescopic device is arranged on the surface of the first measuring ruler. The telescopic device includes an installation groove. The installation groove is opened on the surface of the second measuring ruler. The limiting groove is opened on the surface of the first measuring ruler. The limiting groove is opened on the surface of the third measuring ruler. The surface of the installation groove is fixedly connected with an installation block. The surface of the installation block is fixedly connected with a limiting spring. One end of the limiting spring far away from the installation block is fixedly connected with a connecting block. The surface of the connecting block is provided with a fixing plate. One side of the fixing plate is fixedly connected with a linkage block. The surface of the linkage block is fixedly connected with a T-shaped pin.

[0007] Preferably, the linkage block is fixedly connected to the surface of the fixing plate. The linkage block is arranged inside the connecting block. The number of the linkage blocks is two. The two linkage blocks are symmetrically arranged about the first measuring ruler in the left-right direction.

[0008] Preferably, the two ends of the fixing plate are chamfered. The number of the fixing plates is four. The four fixing plates are symmetrically arranged about the second measuring ruler in the diagonal direction.

[0009] Preferably, the T-shaped pin is in a T shape. The T-shaped pin is in contact with the surface of the connecting block. The T-shaped pin is located in the middle of the limiting spring. The T-shaped pin is located inside the connecting block. The limiting pin penetrates through the surface of the connecting block.

[0010] Preferably, the support device is arranged on the surface of the first measuring ruler and the surface of the third measuring ruler. The support device includes an installation guide plate. The installation guide plate is fixedly connected with the third measuring ruler. A slider is slidably connected in the guide groove of the installation guide plate. The surface of the slider is fixedly connected with a limiting block. The surface of the limiting block is sleeved and connected with a linkage frame. A fastening bolt is threadedly connected to the surface of the slider. The surface of the linkage frame is fixedly connected with a telescopic support. The surface of the telescopic support is fixedly connected with a buckle. The surface of the first measuring ruler is fixedly connected with a card slot. A clamping block is slidably connected to the surface of the card slot. A guiding groove is opened on the surface of the card slot. The surface of the clamping block is fixedly connected with a guiding block. The surface of the card slot is fixedly connected with a limiting support.

[0011] Preferably, threaded grooves are formed on the surface of the slider, and the fastening bolts are threadedly connected to the inner walls of the threaded grooves.

[0012] Preferably, limiting holes are formed on the surface of the clamping block, and the snap fastener is located inside the clamping block.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In the present utility model, by providing a telescopic device, when a tester needs to detect a high-rise building and adjust the length of the detection ruler, the tester only needs to pull the third measuring ruler upward. When the third measuring ruler is completely pulled out and the length is still insufficient, continue to pull it upward to drive the second detection ruler to move upward until it reaches the notch of the limiting groove. The limiting spring loses the restriction of the first measuring ruler and the third measuring ruler, drives the connecting block and the fixing plate to reset, and rotates the fixing plate in a reset manner. The fixing plate can be rotated horizontally with the cooperation of the linkage plate and the limiting pin to block the limiting groove, thus completing the fixation of the positions of the second measuring ruler and the third measuring ruler. When the detection ruler is used up and its length needs to be retracted, just as above, rotate the fixing plate to make it vertical, hold the fixing plate, the second measuring ruler moves downward, the fixing plate slides into the first measuring ruler, and the limiting spring is compressed and deformed, so that it can be retracted into the first measuring ruler. The third measuring ruler repeats the operation of the second detection ruler. By providing a telescopic device, the length can be adjusted according to actual needs. Whether it is measuring the walls and floors of small rooms or the outer facades, beams and columns of large building structures, it can be flexibly handled. It can also be retracted to a smaller size and placed in a toolbox or a bag carried with you, greatly reducing the occupied space and improving the mobility of the tester.

[0015] 2. In the present utility model, by providing a supporting device, when the detection ruler needs to be supported, the operator holds the guiding block with one hand and moves it upward, driving the clamping block to move upward at the same time. When it moves to the uppermost end of the guiding groove, rotate the guiding block to make it horizontal and place it on the upper end of the limiting bracket. The snap fastener loses its fixing effect. Then, rotate the fastening bolt counterclockwise. The fastening bolt cooperates with the installation guide plate to lose the fastening effect on the slider. Immediately, the slider moves downward under the guidance of the installation guide plate, driving the limiting block, the linkage frame and the telescopic support to move downward at the same time. When the telescopic support moves downward, it can support the position of the detection ruler. When the operator manually adjusts it to a suitable support angle, the fastening bolt can be rotated clockwise to fix the slider so that it cannot continue to slide downward, thus completing the support operation of the detection ruler. By providing a supporting device, when the tester needs to perform verticality detection at different wall heights, only by simply adjusting the length of the supporting device, the measurement work can be quickly started without frequently replacing detection tools or performing complex equipment adjustments, improving the overall efficiency of the detection work.

[0024] Please refer to Figures 1 - 6 , the present utility model provides a technical solution: a building inspection ruler for building engineering inspection, including a first measuring ruler 1, a second measuring ruler 2 and a telescopic device 4. The second measuring ruler 2 is arranged on the surface of the first measuring ruler 1, the third measuring ruler 3 is arranged on the surface of the second measuring ruler 2, and the telescopic device 4 is arranged on the surface of the first measuring ruler 1.

[0025] Next, specifically describe the specific settings and functions of its telescopic device 4 and support device 5.

[0026] In this embodiment: The telescopic device 4 includes an installation groove 41. The surface of the second measuring ruler 2 is provided with the installation groove 41. The surface of the first measuring ruler 1 is provided with a limiting groove 42. The surface of the third measuring ruler 3 is provided with a limiting groove 42. The surface of the installation groove 41 is fixedly connected with an installation block 43. The surface of the installation block 43 is fixedly connected with a limiting spring 44. One end of the limiting spring 44 far away from the installation block 43 is fixedly connected with a connecting block 45. The surface of the connecting block 45 is provided with a fixing plate 46. One side of the fixing plate 46 is fixedly connected with a linkage block 47. The surface of the linkage block 47 is fixedly connected with a T-shaped pin 48.

[0027] Specifically, the linkage block 47 is fixedly connected to the surface of the fixing plate 46. The linkage block 47 is arranged inside the connecting block 45. The number of the linkage blocks 47 is two. The two linkage blocks 47 are symmetrically arranged about the first measuring ruler 1 in the left-right direction.

[0028] The effect achieved by the above components is that the direction of the fixing plate 46 can be controlled through the cooperation of the linkage block 47 and the T-shaped pin 48.

[0029] Specifically, both ends of the fixing plate 46 are chamfered. The number of the fixing plates 46 is four. The four fixing plates 46 are symmetrically arranged diagonally about the second measuring ruler 2.

[0030] The effect achieved by the above components is that through the cooperation of the fixing plate 46 and the limiting spring 44, it is more convenient for it to slide into the installation groove 41 when contracting.

[0031] Specifically, the T-shaped pin 48 is T-shaped. The T-shaped pin 48 is in contact with the surface of the connecting block 45. The T-shaped pin 48 is located in the middle of the limiting spring 44. The T-shaped pin 48 is located inside the connecting block 45. The limiting pin penetrates through the surface of the connecting block 45.

[0032] The effect achieved by the above components is that through the T-shaped pin 48, a linkage effect can be exerted on the rotation position of the linkage block 47.

[0033] Specifically, a support device 5 is arranged on the surface of the first measuring ruler 1. A support device 5 is arranged on the surface of the third measuring ruler 3. The support device 5 includes an installation guide plate 51. The installation guide plate 51 is fixedly connected with the third measuring ruler 3. A slider 52 is slidably connected in the guide groove of the installation guide plate 51. The surface of the slider 52 is fixedly connected with a limiting block 53. A linkage frame 54 is sleeved and connected to the surface of the limiting block 53. A fastening bolt 55 is threadedly connected to the surface of the slider 52. A telescopic support 56 is fixedly connected to the surface of the linkage frame 54. A buckle 57 is fixedly connected to the surface of the telescopic support 56. A card slot 58 is fixedly connected to the surface of the first measuring ruler 1. A card block 59 is slidably connected to the surface of the card slot 58. A guiding groove 510 is provided on the surface of the card slot 58. A guiding block 511 is fixedly connected to the surface of the card block 59. A limiting support 512 is fixedly connected to the surface of the card slot 58.

[0034] The effect achieved by the above components is that the support angle of the telescopic bracket 56 can be adjusted through the cooperation of the mounting guide plate 51 and the slider 52.

[0035] Specifically, a threaded groove is formed on the surface of the slider 52, and the fastening bolt 55 is threadedly connected to the inner wall of the threaded groove.

[0036] The effect achieved by the above components is that the position of the slider 52 can be restricted through the cooperation of the fastening bolt 55 and the mounting guide plate 51.

[0037] Specifically, a limiting hole is formed on the surface of the clamping block 59, and the buckle 57 is located inside the clamping block 59.

[0038] The effect achieved by the above components is that the buckle 57 can be fixed and restricted through the cooperation of the clamping block 59 and the clamping groove 58.

[0039] Working principle: When the inspector needs to inspect a high-rise building and needs to adjust the length of the inspection ruler, just pull out the third measuring ruler 3 upwards. When the third measuring ruler 3 is completely pulled out, if the length is still insufficient, continue to pull it upwards, driving the second inspection ruler to move upwards until it reaches the notch of the limit groove 42. The limit spring 44 loses the restriction of the first measuring ruler 1 and the third measuring ruler 3, driving the connecting block 45 and the fixing plate 46 to reset. Rotate the fixing plate 46 during the reset process. The fixing plate 46 can be rotated horizontally under the cooperation of the linkage plate and the limit pin, and then it can be stuck in the limit groove 42, thus completing the fixation of the positions of the second measuring ruler 2 and the third measuring ruler 3. When the inspection ruler is used up and needs to be retracted, just rotate the fixing plate 46 as above to make it vertical, hold the fixing plate 46, the second measuring ruler 2 moves downwards, the fixing plate 46 slides into the first measuring ruler 1, and the limit spring 44 is deformed by extrusion, so that it can be retracted into the first measuring ruler 1. The third measuring ruler 3 can repeat the operation of the second inspection ruler. By setting the telescopic device 4, the length can be adjusted according to actual needs. Whether it is measuring the walls and floors of small rooms or the outer facades, beams and columns of large building structures, it can respond flexibly. It can also be retracted to a smaller size and placed in a toolbox or a bag carried with you, greatly reducing the occupied space and improving the mobility convenience of the inspector;

[0040] In addition, by setting up the support device 5, when it is necessary to support the inspection ruler, the operator holds the guiding block 511 with one hand and moves it upward, driving the clamping block 59 to move upward simultaneously. When it moves to the uppermost end of the guiding groove 510, the guiding block 511 is rotated to make it horizontal and placed on the upper end of the limiting bracket 512. The buckle 57 loses its fixing effect. Subsequently, the fastening bolt 55 is rotated counterclockwise. The fastening bolt 55 cooperates with the installation guide plate 51 and loses its fastening effect on the slider 52. Immediately, the slider 52 moves downward under the guidance of the installation guide plate 51, driving the limiting block 53, the linkage frame 54 and the telescopic bracket 56 to move downward simultaneously. When the telescopic bracket 56 moves downward, it can support the position of the inspection ruler. When the operator manually adjusts it to the appropriate support angle, the fastening bolt 55 can be rotated clockwise to fix the slider 52 so that it cannot continue to slide downward. In this way, the support operation for the inspection ruler is completed. By setting up the support device 5, when the inspector needs to perform verticality detection at different wall heights, simply adjusting the length of the support device 5 can quickly start the measurement work without frequently replacing inspection tools or performing complex equipment adjustments, improving the overall efficiency of the detection work.
