Description

Technical Field

[0001] This utility model relates to the field of level measurement technology, specifically a portable retractable rebar level. Background Technology

[0002] Rebar anchoring technology is a simple and effective connection and anchoring technique for concrete structures. It can be used to insert ordinary steel bars or bolt-type anchor bars. It is now widely used in the reinforcement and renovation of existing buildings, such as: remedying missing steel bars or steel bars that deviate from the design position during construction, adding reinforcement bars to increase the cross-section of components, extending beams and columns for the expansion and jacking of the superstructure, adding columns to buildings and adding shear walls to high-rise buildings, etc.

[0003] In order to ensure that the inserted rebars are on the same horizontal plane during the rebar installation process, a level is needed to measure the rebars to avoid misalignment and reduce the reinforcement effect. The standard for rebar installation is generally one rebar at a spacing of 50 cm. However, the existing levels are usually too short to position multiple rebars at once. Therefore, a level must be used to measure before each rebar is installed, which is troublesome, increases the workload of workers, and reduces the efficiency of the rebar installation process. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a portable, extendable rebar level, which solves the problem that traditional levels cannot position multiple rebars at once during rebar installation. This avoids the need for workers to measure each rebar before installation, reduces their workload, and improves the efficiency of rebar installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable telescopic rebar level, comprising a base, with multiple sets of telescopic rods slidably installed inside both ends of the base. Positioning frames are connected to one side surface of each telescopic rod via a moving mechanism and the lower surface of the base. A support mechanism is provided at one end of each telescopic rod. An adjusting screw is threadedly connected inside the positioning frame. A positioning block is rotatably connected to the lower end of the adjusting screw. A groove is formed on one side surface of the adjusting screw, and a pointer is slidably connected inside the groove. A rotating ring is fixedly connected to one end of the pointer and is sleeved on the upper end of the adjusting screw. A scale line is provided on one side of the groove, corresponding to the pointer. A level is fixedly connected to the upper surface of the base.

[0006] Preferably, the moving mechanism includes a moving ring, which is sleeved on the side surface of the telescopic rod. A hinge seat is provided below the moving ring, and the hinge seat is fixedly connected to the side surface of the moving ring. The lower end of the hinge seat is fixedly connected to the upper end of the positioning frame.

[0007] Preferably, a fastening screw is threadedly connected to the side surface of the movable ring, the fastening screw is disposed opposite to the hinge seat, and a limit ring is provided on one side of the movable ring, the limit ring being fixedly connected to the side surface of the telescopic rod.

[0008] Preferably, the support mechanism includes an adjusting plate, which is hinged to one end of a telescopic rod, and support rods are hinged to both ends of the adjusting plate. The lower end of the support rod is connected to a support seat through the adjusting mechanism.

[0009] Preferably, the adjusting mechanism includes a lead screw rotatably connected inside the support base. A slider is symmetrically threaded onto the side surface of the lead screw, and the upper surface of the slider is hinged to the lower end of the support rod. A rotary knob is fixedly connected to one end of the lead screw through the support base.

[0010] Preferably, a limiting rod is slidably connected inside one side of the positioning frame, and the lower end of the limiting rod is fixedly connected to the upper surface of the positioning block.

[0011] This invention provides a portable, extendable rebar level. Compared with existing technologies, it has the following advantages: The positioning frame, connected by a moving mechanism to the lower surface of the base and one end of the telescopic rod, and the positioning block inside the positioning frame connected by an adjusting screw, cooperate with the lead screw and slider in the support mechanism and adjustment mechanism at both ends of the telescopic rod. This solves the problem that traditional levels cannot position multiple rebars at once during rebar installation, avoiding the need for workers to measure before each rebar is installed, reducing the inconvenience and workload for workers, and improving the efficiency of rebar installation.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a portable telescopic rebar level, including a base 1. Multiple sets of telescopic rods 102 are slidably installed inside both ends of the base 1. One side surface of each set of telescopic rods 102 is connected to a positioning frame 3 via a moving mechanism and the lower surface of the base 1. A support mechanism is provided at one end of each telescopic rod 102. An adjusting screw 304 is threadedly connected inside the positioning frame 3. A positioning block 301 is rotatably connected to the lower end of the adjusting screw 304. A groove 305 is provided on one side surface of the adjusting screw 304. A pointer 302 is slidably connected inside the groove 305. A rotating ring 307 is fixedly connected to one end of the pointer 302. The rotating ring 307 is sleeved on the upper end of the adjusting screw 304. A scale line 303 is provided on one side of the groove 305, and the scale line 303 corresponds to the pointer 302. A level 101 is fixedly connected to the upper surface of the base 1.

[0019] As a technical optimization of this utility model, the moving mechanism includes a moving ring 4, which is sleeved on the side surface of the telescopic rod 102. A hinge seat 402 is provided below the moving ring 4, and the hinge seat 402 is fixedly connected to the side surface of the moving ring 4. The lower end of the hinge seat 402 is fixedly connected to the upper end of the positioning frame 3. The position of the positioning frame 3 can be moved through the moving ring 4 and the hinge seat 402, thereby facilitating the adjustment of the spacing of the positioning frame 3. A fastening screw 401 is threadedly connected to the side surface of the moving ring 4. The fastening screw 401 is arranged opposite to the hinge seat 402. A limit ring 103 is provided on one side of the moving ring 4, and the limit ring 103 is fixedly connected to the side surface of the telescopic rod 102. The moving ring 4 can be positioned through the fastening screw 401 on the side surface of the moving ring 4 and the limit ring 103 on one side of the moving ring 4, thus preventing the moving ring 4 from sliding after the moving ring 4 and the positioning frame 3 are moved to the designated position.

[0020] As a technical optimization of this utility model, the support mechanism includes an adjusting plate 2, which is hinged to one end of a telescopic rod 102. Support rods 202 are hinged to both ends of the adjusting plate 2. The lower end of the support rods 202 is connected to a support seat 201 through the adjusting mechanism. The support mechanism can support the base 1, facilitating the rebar installation operation. The adjusting mechanism includes a lead screw 204, which is rotatably connected inside the support seat 201. A slider 203 is symmetrically threaded on the side surface of the lead screw 204. The upper surface of the slider 203 is hinged to the lower end of the support rod 202. One end of the lead screw 204 passes through the support seat 201 and is fixedly connected to a rotary knob 205. The adjusting mechanism can adjust the base 1 to a horizontal state to prevent the base 1 from tilting.

[0021] As a technical optimization of this utility model, a limiting rod 306 is slidably connected inside one side of the positioning frame 3. The lower end of the limiting rod 306 is fixedly connected to the upper surface of the positioning block 301. The limiting rod 306 slidably connected inside the positioning frame 3 can limit the positioning block 301 and prevent the positioning block 301 from rotating when adjusting the height of the positioning block 301.

[0022] In use, the base 1 is first moved to the construction site, and then the telescopic rod 102 is pulled to extend it. At this time, the staff observes whether the level 101 on the upper surface of the base 1 is horizontal. If it is tilted, the staff rotates the screw 204 inside the support base 201 according to the tilt. The screw 204 will drive the slider 203 to move relative to it. The slider 203 adjusts the height of the adjusting plate 2 through the support rod 202 to guide the level 101 on the upper surface of the base 1 to be in a horizontal position. Then, the moving ring 4 is moved according to the spacing of the rebars so that the spacing of the positioning blocks 301 is the same as the spacing of the rebars. Then, the fastening screw 401 on the side surface of the moving ring 4 is rotated to tighten and fix the moving ring 4. Then, the staff adjusts the height of the positioning blocks 301 by rotating the adjusting screw 304 inside the positioning frame 3. By observing the pointer 302 and the slide groove 305, the positioning blocks 301 are adjusted to the same height. Then, the staff drills holes along the positioning groove on the lower surface of the positioning block 301 to insert the rebars. At this time, the rebars are at the same horizontal plane.
