Description

Technical Field

[0001] This application relates to the field of construction surveying tools, and in particular to a portable, extendable, and adjustable measuring rod. Background Technology

[0002] In construction, bricklaying gauges are essential tools for controlling wall height, mortar joint thickness, and component elevation, and are widely used in brick masonry and block wall construction. Traditional bricklaying gauges are typically fixed-length wooden or metal rods, pre-customized based on common wall heights. However, in actual construction, due to significant differences in wall heights across different buildings—from low walls in low-rise buildings to high walls in high-rise buildings—the required gauge lengths vary. Construction workers often need to carry multiple gauges of different lengths to meet diverse needs, which not only increases the burden of carrying tools but also risks delaying construction progress due to the omission of gauges of the appropriate length.

[0003] To address this problem, a portable, retractable, and adjustable counting rod has been invented. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of fixed length, inconvenience in carrying, poor installation stability, easy to affect measurement accuracy, and cumbersome adjustment of existing tachymeter bars, and to provide a portable, telescopic and adjustable tachymeter bar.

[0005] This application provides a portable, retractable, and adjustable measuring rod, which adopts the following technical solution: it includes multiple sections of rod that can be spliced ​​and disassembled and each section is retractable and adjustable; a tripod base for support; a connecting mechanism installed at the splicing joint of the rod; a sliding frame that can move on the rod; and an adjustment and locking mechanism for adjusting the sliding frame; the sliding frame is provided with an angle adjustment mechanism, and an infrared level is installed on the angle adjustment mechanism.

[0006] Optionally, the rod body includes an outer cylinder, an inner cylinder, and a telescopic locking assembly. The inner cylinder can slide up and down inside the outer cylinder, and a pull-out part is provided at the end of the inner cylinder.

[0007] Optionally, the telescopic locking assembly includes a telescopic positioning hole arranged along the length of the rod and a telescopic positioning pin adapted to the telescopic positioning hole. The telescopic positioning hole is opened on the inner cylinder, and a first compression spring is fitted on the telescopic positioning pin. The other end of the first compression spring is connected to the outer cylinder, and a pull ring is provided on the telescopic positioning pin.

[0008] Optionally, the top of the tripod base is connected to the rod body, and a swingable support rod is hinged to its bottom. The top of the tripod base is provided with a threaded part, and an adjusting bolt is threadedly connected to the threaded part. A movable frame is connected to the bottom of the adjusting bolt, and a hinged rod corresponding to the support rod is hinged to the movable frame. The bottom of the support rod is provided with a support foot, and a fastening bolt is provided between the support foot and the support rod.

[0009] Optionally, the connecting mechanism includes a plurality of positioning slots at one end of the rod splicing point, and a positioning protrusion at the other end that can cooperate with the positioning slots. A first magnetic block is provided in the middle of the positioning protrusion, and a second magnetic block that can attract and cooperate with the first magnetic block is provided in the positioning slot. The splicing of the rod is achieved through the cooperation between the positioning protrusion and the positioning slot, and between the first magnetic block and the second magnetic block.

[0010] Optionally, the adjustment and locking mechanism includes a movable block, slots formed on the inner and outer cylinders, and two teeth that can be embedded between two adjacent slots. A connecting spring is provided between the two teeth, and a push plate is provided on each of the two teeth. By pushing and pulling the two push plates, the teeth can be retracted into the movable block.

[0011] Optionally, the angle adjustment mechanism includes a fixed base, a rotatable rotating screw on the fixed base, a sliding block on the fixed base that is threadedly connected to the rotating screw, a swing plate hinged to the fixed base, a connecting rod hinged between the sliding block and the swing plate, an infrared level on the swing plate, and a handle at one end of the rotating screw.

[0012] Optionally, the rod is made of a lightweight, high-strength alloy material, and each rod surface is provided with high-precision scale markings.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. Flexible and adjustable length, wide range of applications: The multi-section, detachable, and telescopically adjustable pole design allows for both increasing the overall length through splicing and fine-tuning the length by sliding the inner and outer cylinders of individual pole sections. This adapts to the construction needs of walls of different heights, eliminating the need to carry multiple gauge poles and improving the versatility of the tool.

[0015] 2. High portability: The pole is made of lightweight, high-strength alloy material, which reduces the overall weight. Each section of the pole can be disassembled, and a single section can be retracted to its shortest state, making it convenient for transportation and carrying, especially suitable for scenarios where frequent movement is required between construction sites.

[0016] 3. Stable and reliable installation: The tripod base can control the opening angle of the support rods through adjusting bolts, ensuring stable support under different ground conditions. The anti-slip rubber pads at the ends of the support legs further enhance the anti-slip performance and prevent the rods from tipping over and affecting measurement accuracy.

[0017] 4. High measurement accuracy: The pole surface is equipped with high-precision scale markings, and together with an adjustable infrared level, it can quickly and accurately control the wall elevation and verticality, reduce manual reading errors, and improve construction quality.

[0018] 5. Simple and quick operation: The design of the telescopic locking component, connecting mechanism and adjusting locking mechanism makes the telescopic, splicing and fixed operation of the pole and sliding frame simple and easy. The angle adjustment mechanism can accurately adjust the angle of the infrared level by turning the screw, which makes it easy for construction personnel to quickly get started.

[0019] 6. Flexible angle adjustment to adapt to various scenarios: The angle adjustment mechanism allows for flexible adjustment of the infrared level's angle. By rotating the handle, the relevant components can be moved, easily changing the illumination angle of the infrared level. Whether for horizontal measurement, vertical calibration, or tilt angle construction needs, it can accurately adapt to meet the diverse requirements of angle measurement in different construction scenarios, further enhancing the tool's practicality and applicability.

[0031] Reference Figure 1 , Figure 2 One embodiment shown is as follows: The portable, telescopic, and adjustable counting rod includes multiple rod sections 1, which are connected and disassembled by a connecting mechanism 3, and each rod section 1 can be telescopically adjusted; a tripod base 2 for supporting the entire device is connected to the bottom of the rod section 1; a connecting mechanism 3 is installed at the joint of the rod section 1; a sliding frame 4 that can move along its length is movably arranged on the rod section 1, and an adjustment and locking mechanism 5 is installed on the sliding frame 4, which can fix the sliding frame 4 at a specific position on the rod section 1 by adjusting the locking mechanism 5; an angle adjustment mechanism 6 is connected to one side of the sliding frame 4, and an infrared level 7 is installed at the movable end of the angle adjustment mechanism 6. In this embodiment, the rod 1 is set vertically, the tripod base 2 is located at the bottom of the rod 1 and supports the entire rod 1, the connecting mechanism 3 is located between the ends of two adjacent rod sections, the sliding frame 4 is sleeved on the outside of the rod 1 and can slide up and down, the angle adjustment mechanism 6 is horizontally connected to the side of the sliding frame 4, and the infrared level 7 can achieve multi-angle rotation through the angle adjustment mechanism 6.

[0032] The implementation principle of the above embodiment is as follows: multiple rod segments 1 are spliced ​​together to the required length through the connecting mechanism 3, and the length is further adjusted by the telescopic adjustment function of the rod segments 1 themselves; the tripod base 2 stably supports the entire device to ensure that the rod segments 1 are vertical; after the sliding frame 4 slides on the rod segments 1 to a suitable height, it is fixed by the adjustment locking mechanism 5; the angle adjustment mechanism 6 adjusts the angle of the infrared level 7 so that the infrared level 7 can accurately emit horizontal or inclined infrared rays, and achieve accurate measurement in conjunction with the rod segments 1.

[0033] Reference Figure 2 , Figure 3 , Figure 4 One embodiment is shown as follows: The rod body 1 consists of an outer cylinder 8, an inner cylinder 9, and a telescopic locking assembly 10. The outer cylinder 8 is a hollow tubular structure, and the outer diameter of the inner cylinder 9 is slightly smaller than the inner diameter of the outer cylinder 8. The inner cylinder 9 is fitted inside the outer cylinder 8 and can slide up and down along the length of the outer cylinder 8. The upper end of the inner cylinder 9 extends beyond the upper end of the outer cylinder 8, and a pull-out part 11 is connected to the top of the inner cylinder 9. The pull-out part 11 is a circular slot. The telescopic locking assembly 10 is installed on the side wall of the outer cylinder 8 and is used to fix the inner cylinder 9 to the outer cylinder 8 after it slides to a suitable position. In this embodiment, the outer cylinder 8 is vertically arranged, the inner cylinder 9 is coaxially arranged inside the outer cylinder 8, and the pull-out part 11 is horizontally connected to the top of the inner cylinder 9, making it convenient for the operator to pull the inner cylinder 9.

[0034] The implementation principle of the above embodiment is as follows: when it is necessary to adjust the length of the single-section rod 1, the inner cylinder 9 is pulled by the pull-out part 11, so that the inner cylinder 9 slides upward inside the outer cylinder 8. When it slides to the required length, the inner cylinder 9 is fixed to the outer cylinder 8 by the telescopic locking component 10 to prevent the inner cylinder 9 from sliding on its own inside the outer cylinder 8, thereby realizing the adjustment of the length of the single-section rod 1.

[0035] Reference Figure 2 , Figure 3 , Figure 4 , Figure 6One embodiment shown is as follows: The telescopic locking assembly 10 includes a telescopic positioning hole 12 and a telescopic positioning pin 13. The telescopic positioning hole 12 is evenly opened on the side wall of the inner cylinder 9 along the length direction of the inner cylinder 9 and penetrates the side wall of the inner cylinder 9. A through hole is opened on the side wall of the outer cylinder 8 at the position corresponding to the telescopic positioning hole 12. The telescopic positioning pin 13 passes through the through hole and can slide in the through hole. The diameter of the telescopic positioning pin 13 is adapted to the diameter of the telescopic positioning hole 12. A first compression spring 14 is fitted on the telescopic positioning pin 13. One end of the first compression spring 14 is connected to the middle of the telescopic positioning pin 13, and the other end is connected to the inner wall of the outer cylinder 8. A pull ring 15 is connected to the end of the telescopic positioning pin 13 located outside the outer cylinder 8. The pull ring 15 has a ring structure. In this embodiment, the telescopic positioning holes 12 are distributed along the height direction of the inner cylinder 9, the telescopic positioning pin 13 passes horizontally through the side wall of the outer cylinder 8, and when the first compression spring 14 is in its natural state, the inner end of the telescopic positioning pin 13 is inserted into the telescopic positioning hole 12, and the pull ring 15 is located on the outside of the outer cylinder 8.

[0036] The implementation principle of the above embodiment is as follows: When the inner cylinder 9 needs to be telescopic, pull the pull ring 15 to drive the telescopic positioning pin 13 to move outward, so that the telescopic positioning pin 13 disengages from the telescopic positioning hole 12. At this time, the first compression spring 14 is compressed. After the inner cylinder 9 slides to the appropriate position in the outer cylinder 8, release the pull ring 15, the first compression spring 14 restores its deformation, pushes the telescopic positioning pin 13 to move inward and insert into the corresponding telescopic positioning hole 12, thereby fixing the inner cylinder 9 and the outer cylinder 8 and realizing the telescopic locking of the rod 1.

[0037] Reference Figure 2 , Figure 5 , Figure 7One embodiment shown is as follows: The top center of the tripod base 2 is fixed to the bottom end of the rod 1 by a threaded connection. The bottom edge of the tripod base 2 is evenly distributed along the circumferential direction and is hinged with three support rods 16. The support rods 16 can swing outward around the hinge point. The top outer side of the tripod base 2 has an integrally formed threaded part 17. An adjusting bolt 18 is threaded onto the threaded part 17. The adjusting bolt 18 is set in a vertical position. The bottom of the adjusting bolt 18 is connected to a movable frame 19 by a rotatable connection. The movable frame 19 has a circular ring structure. The outer side of the movable frame 19 is hinged with three hinge rods 20 along the circumferential direction. The other end of each hinge rod 20 away from the movable frame 19 is hinged to the middle of the corresponding support rod 16. The bottom end of the support rod 16 is provided with a support foot. A fastening bolt is provided between the support foot and the bottom end of the support rod 16. The fastening bolt passes horizontally through the connection part between the support foot and the support rod 16, fixing the support foot and the support rod 16 together. In this embodiment, the tripod base 2 is placed horizontally, the pole 1 is vertically connected to the center of its top, and the support rod 16 is radially distributed downward and outward at the bottom of the tripod base 2 in its natural state. The adjusting bolt 18 is located directly above the center of the tripod base 2, and the movable frame 19 is sleeved on the outside of the pole 1 and located directly below the adjusting bolt 18. The bottom surface of the support leg is in contact with the ground. When the fastening bolt is tightened, the support leg and the support rod 16 remain relatively fixed. When loosened, the support leg can rotate relative to the support rod 16.

[0038] The implementation principle of the above embodiment is as follows: When it is necessary to adjust the support range and stability of the tripod base 2, the adjusting bolt 18 is rotated. Since the adjusting bolt 18 is threadedly connected to the threaded part 17 of the tripod base 2, the adjusting bolt 18 will move up and down in the vertical direction under the action of the thread, thereby driving the movable frame 19 to move up and down synchronously. When the movable frame 19 moves up and down, it will generate a pulling force or a pushing force on the support rod 16 through the hinge rod 20, causing the support rod 16 to swing around the hinge point with the tripod base 2, thereby changing the opening angle of the support rod 16 to adapt to different ground support requirements. The support feet at the bottom of the support rod 16 increase the contact area with the ground, improve the support stability, and the relative angle between the support feet and the support rod 16 can be adjusted by tightening the bolts, so that the support feet can better fit the ground with different slopes, further enhancing the stability of the entire device in complex ground environments and ensuring that the rod 1 always remains vertical.

[0039] Reference Figure 5 , Figure 6 , Figure 8One embodiment is shown as follows: The connecting mechanism 3 includes positioning slots 21 and positioning protrusions 22. A plurality of positioning slots 21 are evenly distributed on the end face of one section of the rod 1 at the splicing end. The positioning slots 21 are circular grooves located at the bottom of the outer cylinder 8. A positioning protrusion 22 is connected to the end face of the other section of the rod 1 at a position corresponding to the positioning slots 21. The positioning protrusion 22 is cylindrical and located at the top of the inner cylinder 9, with a diameter matching the inner diameter of the positioning slots 21. A first magnetic block 23 is embedded in the middle of the positioning protrusion 22. The first magnetic block 23 is circular and coaxially arranged with the positioning protrusion 22. A second magnetic block 24 is embedded at the bottom of the positioning slots 21. The second magnetic block 24 has opposite magnetic properties to the first magnetic block 23 and is positioned accordingly. In this embodiment, the positioning protrusions 22 and positioning slots 21 correspond one-to-one. When the two sections of the rod 1 are spliced, the positioning protrusions 22 are inserted into the positioning slots 21, and the first magnetic block 23 and the second magnetic block 24 attract each other.

[0040] The implementation principle of the above embodiment is as follows: When splicing the rod 1, the positioning protrusion 22 on one section of the rod 1 is aligned with the positioning slot 21 on the other section of the rod 1 and inserted. At this time, the first magnetic block 23 and the second magnetic block 24 attract each other, and the resulting attraction force makes the positioning protrusion 22 firmly stuck in the positioning slot 21, thus realizing the stable splicing of the two sections of the rod 1. When disassembling, a pulling force greater than the attraction force of the magnetic blocks is applied, and the positioning protrusion 22 can be pulled out from the positioning slot 21, thus completing the disassembly of the rod 1.

[0041] Reference Figure 6 , Figure 9 One embodiment shown is as follows: The adjusting locking mechanism 5 includes a movable block 25, which is a hollow block structure that is fitted onto the rod 1 and connected to the sliding frame 4; the inner cylinder 9 and the outer cylinder 8 are evenly provided with slots 26 along their length on their side walls, and the slots 26 are triangular grooves; the movable block 25 is provided with two sets of teeth 27 inside, the shape of which is adapted to the slots 26 and can be embedded between two adjacent slots 26; the two teeth 27 in each pair are arranged opposite to each other and are connected by a connecting spring 28. When the connecting spring 28 is in its natural state, the outer ends of the two teeth 27 extend out of the movable block 25 and are embedded in the slots 26; a push plate 29 is connected to the outside of the teeth 27, and the push plate 29 extends through the side wall of the movable block 25 to the outside and can slide along the side wall of the movable block 25. In this embodiment, the movable block 25 is fixedly connected to the inner side of the sliding frame 4, the slots 26 are distributed along the height direction of the rod 1, two pairs of teeth 27 are horizontally opposite to each other inside the movable block 25, and the push plate 29 is vertically arranged on the outer side of the movable block 25. By setting a fixed telescopic distance between the inner cylinder 9 and the outer cylinder 8, which can be achieved by setting the distance between two adjacent telescopic positioning holes 12, the slots 26 on the inner cylinder 9 and the outer cylinder 8 can be completely or partially overlapped, thereby facilitating the movement of the movable block 25.

[0042] The implementation principle of the above embodiment is as follows: When it is necessary to move the sliding frame 4, push the two push plates 29 towards the middle. The push plates 29 drive the locking teeth 27 to retract into the movable block 25, the connecting spring 28 is compressed, and the locking teeth 27 disengage from the slot 26. At this time, the sliding frame 4 can slide freely along the rod 1. When the sliding frame 4 reaches the required position, release the push plates 29, the connecting spring 28 restores its deformation, pushes the two locking teeth 27 to extend outward and embed into the corresponding slot 26, thereby fixing the movable block 25 to the rod 1, and thus locking the sliding frame 4.

[0043] Reference Figure 1 , Figure 6 One embodiment shown is as follows: The angle adjustment mechanism 6 includes a fixed base 30, which is a cuboid structure and is fixedly connected to the side of the sliding frame 4; one end of the fixed base 30 is connected to a rotating screw 31 via a bearing, the rotating screw 31 is horizontally arranged, and its axis is consistent with the length direction of the fixed base 30; a sliding groove is provided on the top of the fixed base 30, and a sliding block 32 is provided in the sliding groove. The bottom of the sliding block 32 is adapted to the sliding groove and can slide along the sliding groove. A thread is provided in the middle of the sliding block 32. A hole is threadedly connected to the rotating screw 31; a swing plate 33 is hinged to the end of the fixed seat 30 away from the rotating screw 31, and the swing plate 33 can swing up and down around the hinge point; a connecting rod 34 is hinged between the top of the sliding block 32 and the middle of the swing plate 33, and the two ends of the connecting rod 34 are respectively hinged to the sliding block 32 and the swing plate 33 through pins; an infrared level 7 is fixedly installed at the free end of the swing plate 33; a handle 35 is connected to the outer end of the rotating screw 31, and its edge is provided with anti-slip texture. In this embodiment, the fixed seat 30 is horizontally connected to the sliding frame 4, the rotating screw 31 is arranged along the length direction of the fixed seat 30, the sliding block 32 slides horizontally in the sliding groove of the fixed seat 30, and the connecting rod 34 is hinged between the sliding block 32 and the swing plate 33.

[0044] The implementation principle of the above embodiment is as follows: rotating the handle 35 drives the rotating screw 31 to rotate. Since the sliding block 32 is threadedly connected to the rotating screw 31 and cannot rotate due to the restriction of the sliding groove, the sliding block 32 will slide along the length direction of the rotating screw 31. When the sliding block 32 slides, the connecting rod 34 pulls or pushes the swing plate 33, causing the swing plate 33 to swing around its hinge point with the fixed base 30, thereby adjusting the angle of the infrared level 7 on the swing plate 33 and realizing the precise adjustment of the irradiation angle of the infrared level 7.

[0045] Reference Figure 1 , Figure 2One embodiment is shown as follows: the rod 1 is made of a lightweight, high-strength alloy material, such as aluminum alloy or titanium alloy, which is characterized by its light weight and high strength; each rod 1 has a high-precision scale marking along its length on its outer surface, with the scale markings in millimeters, clearly indicating the length of the rod 1. In this embodiment, the scale markings are located on the front of the rod 1, increasing sequentially from the bottom of the rod 1 upwards.

[0046] The implementation principle of the above embodiment is as follows: the lightweight and high-strength alloy material enables the rod 1 to reduce the overall weight while ensuring sufficient strength to support the entire device, making it easy to carry and operate; the high-precision scale markings can provide accurate length references for construction measurement, and together with the infrared level 7, operators can quickly read the measurement data and improve the construction accuracy.

[0047] The working principle of this device is as follows: In use, multiple sections of rod 1 are first assembled via the connecting mechanism 3. Positioning protrusions 22 are inserted into positioning slots 21, and magnetic blocks are used for fixation. A single section of rod 1 can pull the inner cylinder 9, and the telescopic positioning pin 13 engages with the positioning hole to complete telescopic movement. Rod 1 is connected to the tripod base 2. Rotating the adjusting bolt 18 drives the movable frame 19, causing the hinge rod 20 to pull the support rod 16 open. The support legs are adjusted by tightening bolts, and anti-slip pads enhance stability. The sliding frame 4 slides along rod 1 to the target height, pushing the push plate 29 to retract the locking teeth 27. After reaching the target position, it is released, and the locking teeth 27 are fixed in the slot 26. Rotating the handle 35 drives the rotating screw 31, causing the sliding block 32 to move. The connecting rod 34 pulls the swing plate 33, adjusting the angle of the infrared level 7. Using the scale of rod 1 and the infrared light from the level, precise control of wall elevation and verticality is achieved.

[0048] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
