Description

Technical Field

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

[0002] A construction ruler is a tool used to measure various geometric parameters of a building, including verticality. This ruler is specifically designed to measure the verticality of building elements such as walls, columns, and curtain walls to ensure they meet design requirements and construction standards.

[0003] The Chinese utility model patent application number CN202022905709.X is a wall verticality detection ruler for construction. The manual rocker can be inserted into the slot on the right side of the installation shaft, and the installation shaft and screw are rotated through the slot. The rotation of the screw drives the threaded ring to slide inside the first installation slot. When the threaded ring moves to the left, it drives the third bearing and the rotating shaft to move to the left, so that the support rod supports the vertical ruler. The vertical ruler rotates with the first bearing as the center until the support rod supports the vertical ruler in a vertical shape. The vertical ruler is limited and supported by the support rod. It can effectively ensure the stability of the plumb ruler. The scale groove on the front of the ruler can be used as an angle reference for the angle between the plumb ruler and the ruler. The angle of the plumb ruler is judged according to the distance of the moving scale groove of the threaded ring until the plumb ruler is vertical. When the threaded ring moves to the right, the plumb ruler and the ruler fit together, which is easy to carry. However, each time the plumb ruler and the ruler are opened and closed, the threaded ring needs to move a large distance, which makes the number of turns of the screw driven by the rocker large, resulting in a slow speed in the process of opening and closing the detection ruler, affecting the efficiency of the detection ruler. Utility Model Content

[0004] The purpose of the present utility model is to provide a detection ruler for construction, so as to solve the problem proposed in the above background technology that in the process of opening and closing the vertical ruler and the straight ruler of the existing detection ruler, the threaded ring needs to move a large distance, so that the number of turns driven by the rocker to rotate the screw is large, resulting in a slow speed during the opening and closing process of the detection ruler, affecting the efficiency of the use of the detection ruler.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a detection ruler for construction: comprising a ruler, a plumb line rotatably connected to the surface of the ruler, a guide rod fixedly connected to the surface of the ruler, a movable block slidably connected to the surface of the guide rod, a support rod rotatably connected to the surface of the movable block, a screw rotatably connected to the surface of the ruler, a knob fixedly connected to the surface of the screw, a nut threadedly connected to the surface of the screw, a fixed block fixedly connected to the surface of the nut, a spring fixedly connected to the surface of the fixed block, a limit rod fixedly connected to the surface of the spring, a limit block fixedly connected to the surface of the movable block, a scale groove provided on the surface of the ruler, a guide hole provided on the surface of the ruler, a slider fixedly connected to the surface of the movable block, and a pointer fixedly connected to the surface of the slider.

[0007] Preferably, the vertical ruler is in a "U" shape, and the end of the support rod away from the movable block is rotatably connected to the surface of the vertical ruler.

[0008] Preferably, the movable block slides on the guide groove of the ruler through a guide rod, the screw rotates on the guide groove of the ruler through a knob, and the screw drives the nut to slide on the guide groove of the ruler.

[0009] Preferably, a circular hole is provided on the surface of the fixing block, a circular hole is provided on the surface of the limiting block, the limiting rod slides on the circular hole of the fixing block, and the elastic force of the spring acts on the limiting rod.

[0010] Preferably, the limiting rod passes through the circular hole of the limiting block on the nut, and the nut drives the movable block to slide synchronously on the guide groove of the ruler through the limiting rod.

[0011] Preferably, the slider slides on the guide hole through a movable block, and the slider drives the pointer to slide on the surface of the ruler, and the pointer points to the scale groove on the surface of the ruler.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The detection ruler rotates the plumb ruler on the surface of the ruler, and the plumb ruler drives the movable block to slide on the guide rod through the support rod.

At this time, the screw is rotated by the knob, and the screw drives the nut to slide on the guide groove of the ruler. The nut drives the movable block to slide on the guide groove of the ruler through the limit rod. The movable block drives the plumb ruler to rotate through the support rod, so that the plumb ruler fits the vertical surface of the building, avoiding the trouble of constantly rotating the screw to open the plumb ruler on the ruler, saving the time of constantly rotating the screw, and ensuring the detection efficiency of the detection ruler.

A limit block 12 is fixedly connected, a scale groove 13 is provided on the surface of the ruler 1, a guide hole 14 is provided on the surface of the ruler 1, a slider 15 is fixedly connected to the surface of the movable block 4, and a pointer 16 is fixedly connected to the surface of the slider 15. When the detection ruler opens the vertical ruler 2 on the ruler 1, there is no need to rotate the screw 6. The vertical ruler 2 can be opened by directly rotating it on the ruler 1, avoiding the time wasted in rotating the screw 6 and improving the efficiency of the detection process. At the same time, the pointer 16 is used to point to the scale groove 13 to view the verticality of the building, which reduces the error in the viewing process and thus ensures the accuracy of the detection.

[0024] Furthermore, a guide groove is provided on the surface of the ruler 1, the guide rod 3 is fixedly connected to the guide groove of the ruler 1, the screw 6 is rotatably connected to the guide groove of the ruler 1, and the screw 6 rotates on the guide groove of the ruler 1 through a bearing. The guide rod 3 and the screw 6 are parallel to each other, and the length and diameter of the guide rod 3 and the screw 6 are the same.

[0025] Furthermore, the plumb line 2 is in a "U" shape, and the end of the support rod 5 away from the movable block 4 is rotatably connected to the surface of the plumb line 2. During the sliding process, the movable block 4 drives the plumb line 2 to rotate on the ruler 1 through the support rod 5, and at this time, the two ends of the support rod 5 also rotate on the movable block 4 and the plumb line 2 respectively, and the support rod 5 supports the plumb line 2 on the ruler 1.

[0026] Furthermore, the movable block 4 slides on the guide groove of the ruler 1 through the guide rod 3, the screw 6 rotates on the guide groove of the ruler 1 through the knob 7, and the screw 6 drives the nut 8 to slide on the guide groove of the ruler 1. The nut 8 and the movable block 4 are both block-shaped, but the size of the movable block 4 is larger than the size of the nut 8, thereby reserving an installation position for the support rod 5.

[0028] Furthermore, the limiting rod 11 passes through the circular hole of the limiting block 12 on the nut 8, and the nut 8 drives the movable block 4 to slide synchronously on the guide groove of the ruler 1 through the limiting rod 11. The nut 8 can also limit the position of the movable block 4 through the limiting rod 11, and then limit the angle of the vertical ruler 2 through the support rod 5.

[0030] Working principle: Rotate the vertical ruler 2 on the surface of the ruler 1, and the vertical ruler 2 drives the movable block 4 to slide on the guide rod 3 through the support rod 5. At this time, pull the limit rod 11 so that the spring 10 is pulled to deformation, so that the movable block 4 drives the limit block 12 to slide to the same horizontal line as the fixed block 9. Loosen the limit rod 11. Under the elastic force of the spring 10, the limit rod 11 slides on the fixed block 9 to the circular hole that passes through the limit block 12. At this time, rotate the screw rod 6 through the knob 7, and the screw 6 drives the nut 8 to slide on the guide groove of the ruler 1. The nut 8 drives the movable block 4 to slide on the guide groove of the ruler 1 through the limit rod 11. The movable block 4 is driven by the support rod 5 The plumb ruler 2 rotates so that the plumb ruler 2 fits the vertical surface of the building, avoiding the trouble of continuously rotating the screw 6 to open the plumb ruler 2 on the ruler 1, saving the time of continuously rotating the screw 6, and ensuring the detection efficiency of the detection ruler. At the same time, when the movable block 4 slides on the guide groove of the ruler 1, it drives the slider 15 to slide on the guide hole 14, and the slider 15 drives the pointer 16 to slide on the surface of the ruler 1, so that the pointer 16 points to the scale groove 13 on the surface of the ruler 1. The position of the pointer 16 on the scale groove 13 can be used to know the verticality of the building, reducing the error in the viewing process, thereby ensuring the accuracy of the detection.
