A support structure for a precision level

Abstract

This utility model discloses a support structure for a precision level, including a frame upright and two connecting parts. One end of each connecting part is fixedly connected to a connecting sleeve, and one side of each connecting part is fixedly connected to a fixing plate. Both fixing plates are rotatably connected to the connecting upright via bearings. This utility model, by incorporating a limiting rod, sliding column, a lever, and a spring, allows the end of the sliding column to retract, unlocking the enclosed area. Then, the hook is attached to the crossbar of the frame upright or other reliable components. Releasing the lever causes the spring force to push the sliding column outward from within the outer sleeve column, forming a closed latch with the top plate. This prevents the hook from accidentally detaching from the attachment point. This structure ensures that even if the main fixing mechanism fails unexpectedly during high-altitude operations, the safety rope can immediately hold the laser level on the supporting horizontal rod, effectively preventing it from falling and greatly improving operational safety.

Description

Technical Field

[0001] This utility model relates to the field of level support technology, and in particular to a support structure for a precision level. Background Technology

[0002] During construction, temporary concrete formwork support devices are typically erected to ensure that concrete structures are built in the specified positions and form the required shapes. During the formwork erection process, a laser level is used to establish horizontal points. Existing laser levels are generally mounted on dedicated level supports, but these supports have limited height. When the height exceeds the limit of the dedicated level support, a pad needs to be laid on the horizontal bar of the construction scaffold before the laser level is supported. To ensure the stability and accuracy of the laser level, the stability of the support position is crucial, making the erection of the laser level difficult. To address this, CN219036103U discloses "A Laser Level Support Structure." This solution uses connectors and a clamping mechanism to connect the entire support structure to the uprights of the construction scaffold. The specific connection position is determined based on the erection height of the laser level. This utility model's laser level support structure can move up and down along the scaffold uprights as needed, thereby moving the laser level connected to the support member up and down. This not only avoids the height limitations of existing level brackets during use but also ensures the stability of the level bracket setup. It meets the assumed stability requirements of the laser level, and the setup height can be adjusted along the scaffold uprights as needed, with a wider adjustment range. Since the construction scaffold is generally large, even if the scaffold is bumped during operation, it will not affect the position of the laser level. The good stability at the support point avoids level point deviation, thus avoiding rework due to level point deviation and improving the efficiency of structural formwork erection.

[0003] However, in this scheme, since the support structure relies entirely on the static friction between the threaded set screw and the upright for fixation, there is a risk of overall instability and slippage when subjected to accidental collisions, frequent vibrations, or possible loosening of the threaded pair itself during construction. Therefore, a precision level support structure is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a support structure for a precision level.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a precision level support structure, comprising a frame upright and two connecting parts, one end of the two connecting parts being fixedly connected to a connecting sleeve, a fixing plate being fixedly connected to one side of each connecting part, the two fixing plates being rotatably connected to a connecting upright through bearings, a supporting horizontal rod being fixedly connected to the upper surface of the connecting upright, a reinforcing rod being fixedly connected to the bottom of the supporting horizontal rod, the other end of the reinforcing rod being fixedly connected to the bottom of the connecting upright, a laser level being fixedly connected to the supporting horizontal rod through a connecting screw, and an anti-falling structure being provided on the supporting horizontal rod;

[0006] The anti-fall structure includes a fixing ring fixedly connected to the upper surface of the supporting horizontal bar, a safety rope fixedly connected to the fixing ring, and a hook fixedly connected to the other end of the safety rope. Through the cooperation of the hook, the safety rope and the fixing ring, the laser level is effectively prevented from falling from a height due to accident.

[0007] As a further description of the above technical solution:

[0008] One side of the hook is fixedly connected to a top plate, and the other end is fixedly connected to a fixing plate. One side of the fixing plate is fixedly connected to an outer sleeve column, and one side of the outer sleeve column is provided with a moving groove. By moving the lever, the lever slides within the moving groove.

[0009] As a further description of the above technical solution:

[0010] The inner side of the outer sleeve column is slidably connected to a sliding column, which passes through one side of the fixed plate and is slidably connected. The sliding column has a sliding hole inside, and a toggle rod is fixedly connected to one side of the sliding column. The toggle rod is slidably connected in the moving groove. The toggle rod drives the sliding column to slide inside the outer sleeve column, causing the end of the sliding column to retract and unlock the closed area.

[0011] As a further description of the above technical solution:

[0012] The inner part of the outer sleeve column is fixedly connected to a limiting rod, which is slidably connected inside the sliding hole. A spring is sleeved on the limiting rod. One end of the spring is fixedly connected to the inner bottom of the outer sleeve column, and the other end is fixedly connected to one side of the sliding column. The spring force pushes the sliding column to extend outward inside the outer sleeve column, so that the end of the sliding column and the top plate together form a closed latch to prevent the hook from accidentally falling off the mounting point.

[0013] As a further description of the above technical solution:

[0014] The two fixed discs are fixedly connected to a fastening sleeve on opposite sides. A fastening bolt is threaded through one side of the reinforcing rod. Tighten the fastening bolt so that its end abuts against one side of the fastening sleeve, using friction to prevent it from rotating and lock the direction.

[0015] As a further description of the above technical solution:

[0016] The connecting sleeve has an internal threaded adjustment screw. One end of the adjustment screw is fixedly connected to a handle, and the other end is rotatably connected to an arc-shaped abutment. A rubber pad is fixedly connected to one side of the arc-shaped abutment. A locking nut is threaded onto the adjustment screw. Tightening the locking nut tightens the end face of the connecting sleeve, reducing the chance of the adjustment screw loosening during vibration.

[0017] As a further description of the above technical solution:

[0018] Two sliding rods are fixedly connected to one side of the arc-shaped abutment. Each sliding rod passes through one side of the connector and is slidably connected. The arc-shaped abutment drives the sliding rods to slide on the connector, thereby improving the stability of the arc-shaped abutment's movement.

[0019] This utility model has the following beneficial effects:

[0020] 1. Compared with existing technologies, this precision level support structure, through the inclusion of a fixing ring, safety rope, hook, top plate, fixing plate, outer column, limit rod, sliding column, actuating rod, and spring, allows for precise control after the laser level is installed. By manually moving the actuating rod inward, the sliding column compresses the spring and slides into the outer column, causing the end of the sliding column to retract, unlocking the enclosed area. The hook is then attached to the horizontal bar of the frame upright or other reliable components. Releasing the actuating rod allows the spring force to push the sliding column outward within the outer column, forming a closed latch with the top plate. This prevents the hook from accidentally detaching from the mounting point. This structure ensures that even if the main fixing mechanism fails unexpectedly during high-altitude operations, the safety rope can immediately hold the laser level on the support column, effectively preventing it from falling and greatly improving operational safety.

[0021] 2. Compared with the existing technology, the support structure of this precision level instrument, by setting fastening bolts, allows the support level rod to drive the connecting rod to rotate on the fixed plate, thereby adjusting the projection direction of the laser level instrument on the support level rod. After adjusting to the required angle, the fastening bolts can be tightened so that their ends abut against one side of the fastening sleeve, using friction to prevent rotation and lock the direction.

[0031] 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.

[0032] Reference Figures 1 to 7This utility model provides a support structure for a precision level: it includes a frame upright 1 and two connecting parts 2. One end of the two connecting parts 2 is fixedly connected to a connecting sleeve 3. A fixing plate 9 is fixedly connected to one side of each connecting part 2. The two fixing plates 9 are rotatably connected to a connecting upright 11 through bearings. A supporting horizontal rod 13 is fixedly connected to the upper surface of the connecting upright 11. A reinforcing rod 12 is fixedly connected to the bottom of the supporting horizontal rod 13. The other end of the reinforcing rod 12 is fixedly connected to the bottom of the connecting upright 11. A laser level 14 is fixedly connected to the supporting horizontal rod 13 through a connecting screw. The supporting horizontal rod 13 is provided with an anti-fall structure 16. An adjusting screw 4 is threaded inside the connecting sleeve 3. One end of the adjusting screw 4 is fixedly connected to a handle 5, and the other end... A rotatable arc-shaped abutment plate 6 is connected, and a rubber pad is fixedly connected to one side of the arc-shaped abutment plate 6. A locking nut 8 is threaded onto the adjusting screw 4. Two sliding rods 7 are fixedly connected to one side of the arc-shaped abutment plate 6. Each sliding rod 7 passes through one side of the connector 2 and is slidably connected. The connecting hooks at the ends of the two connectors 2 are crossed over the frame upright 1, so that the inner side of the connecting hook abuts against one side of the upright. Then, the handle 5 is rotated to drive the adjusting screw 4 to screw into the connecting sleeve 3, pushing the arc-shaped abutment plate 6 toward the frame upright 1 until the rubber pad on the arc-shaped abutment plate 6 is tightly pressed against the other side of the upright, forming a stable clamp. Then, the locking nut 8 is tightened to press against the end face of the connecting sleeve 3, reducing the probability of the adjusting screw 4 loosening during vibration, thereby completing the fixation of the entire support structure on the frame upright 1.

[0033] To prevent falls, the anti-fall structure 16 includes a fixing ring 161 fixedly connected to the upper surface of the supporting horizontal bar 13. A safety rope 162 is fixedly connected to the fixing ring 161, and a hook 163 is fixedly connected to the other end of the safety rope 162. A top plate 164 is fixedly connected to one side of the hook 163, and a fixing plate 165 is fixedly connected to the other end. An outer sleeve post 166 is fixedly connected to one side of the fixing plate 165. A moving groove is provided on one side of the outer sleeve post 166. A sliding post 168 is slidably connected inside the outer sleeve post 166. The sliding post 168 passes through one side of the fixing plate 165 and is slidably connected. A sliding hole is provided inside the sliding post 168. A toggle rod 169 is fixedly connected to one side of the sliding post 168 and is slidably connected in the moving groove. A limit rod 167 is fixedly connected inside the outer sleeve post 166 and is slidably connected inside the sliding hole. A spring 1610 is sleeved on the limit rod 167. One end of 1610 is fixedly connected to the inner bottom of the outer column 166, and the other end is fixedly connected to one side of the sliding column 168. After the laser level 14 is installed, the lever 169 is moved inward by hand. The lever 169 causes the sliding column 168 to compress the spring 1610 and slide into the outer column 166, so that the end of the sliding column 168 retracts, unlocking the closed area. Then the hook 163 is hooked onto the horizontal bar or other reliable component of the frame upright 1. Then the lever 169 is released. The elastic force of the spring 1610 pushes the sliding column 168 to extend outward inside the outer column 166, so that the end of the sliding column 168 and the top plate 164 together form a closed lock, preventing the hook 163 from accidentally falling off the mounting point. This structure ensures that even if the main fixing mechanism fails unexpectedly during high-altitude operations, the safety rope 162 can immediately pull the laser level 14 on the supporting horizontal bar 13, effectively preventing it from falling and greatly improving the safety of the operation.

[0034] To achieve the locking purpose, fastening sleeves 10 are fixedly connected to the opposite sides of the two fixed plates 9. A fastening bolt 15 is threaded through one side of the reinforcing rod 12. The supporting horizontal rod 13 drives the connecting vertical rod 11 to rotate on the fixed plate 9, thereby adjusting the projection direction of the laser level 14 on the supporting horizontal rod 13. After adjusting to the required angle, the fastening bolt 15 can be tightened so that its end abuts against one side of the fastening sleeve 10, using friction to prevent it from rotating and locking the direction.

[0035] Working principle: After the laser level 14 is installed, use your finger to move the lever 169 inward. The lever 169 causes the sliding column 168 to compress the spring 1610 and slide into the outer column 166, causing the end of the sliding column 168 to retract, unlocking the closed area. Then, hook 163 is attached to the horizontal bar or other reliable component of the frame upright 1. Immediately release the lever 169. The elastic force of the spring 1610 pushes the sliding column 168 to extend outward within the outer column 166, so that the end of the sliding column 168 and the top plate 164 together form a closed latch, preventing... If the hook 163 accidentally detaches from the mounting point, this structure ensures that even if the main fixing mechanism fails unexpectedly during high-altitude operations, the safety rope 162 can immediately pull the laser level 14 on the support horizontal bar 13, effectively preventing it from falling and greatly improving operational safety. The support horizontal bar 13 drives the connecting vertical bar 11 to rotate on the fixed plate 9, thereby adjusting the projection direction of the laser level 14 on the support horizontal bar 13. After adjusting to the required angle, the fastening bolt 15 can be tightened so that its end abuts against one side of the fastening sleeve 10, using friction to prevent it from rotating and locking the direction.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
