Description

Technical Field

[0001] The utility model belongs to the technical field of wall detection, and in particular relates to a wall thickness laser detection device. Background Art

[0002] During construction, in order to ensure the quality of the project, it is necessary to measure and inspect the relevant structures, including the inspection of wall thickness. The thickness of the wall determines the bearing capacity of the house structure to a certain extent.

[0003] The Chinese patent with publication number CN216206061U discloses a wall thickness gauge for house structure detection, comprising a main box, a protective rubber frame is fixedly arranged inside the main box, a laser rangefinder is fixedly installed on the protective rubber frame, one end of the main box is fixedly connected with a telescopic hollow sleeve facing the laser rangefinder, the bottom of the other end of the main box is hinged with a protective box cover, and both ends of the main box close to the telescopic hollow sleeve are fixedly arranged with a winding rack. The utility model is a wall thickness gauge for house structure detection. The wall thickness gauge has a compact structure design, adopts a laser rangefinder to detect the thickness of the wall, is simple and convenient to operate, and has high measurement accuracy. The measurement personnel can realize the clamping of the barb of the rangefinder by pulling the rope, and can realize single-person operation, which effectively avoids the disadvantages of traditional wall thickness measurement that requires the cooperation of multiple people, is time-consuming and labor-intensive, and has low measurement efficiency. It is easy to operate and has strong practicality.

[0004] However, in actual use, when the wall thickness is less than the minimum size of the telescopic hollow sleeve, after the barb card abuts against the wall on one side, the main box of the laser rangefinder cannot be pressed against the wall on the other side, resulting in inaccurate wall thickness data measured by the laser rangefinder, and reducing the minimum size of the telescopic hollow sleeve will cause the elongation of the telescopic hollow sleeve to decrease, thereby affecting the maximum detection thickness of the wall by the laser rangefinder; in summary, in the above scheme, the same model of telescopic hollow sleeve can detect a small range of wall thickness, poor applicability, and is not conducive to actual use. Utility Model Content

[0005] The utility model aims to provide a wall thickness laser detection device to solve the problem of poor applicability of the existing detection devices mentioned above.

[0006] In order to achieve the above object, the utility model provides the following technical solutions: a wall thickness laser detection device, comprising

[0007] The telescopic assembly comprises a main sleeve, an extension sleeve and a stop block, wherein the stop block is slidably fitted in the main sleeve, the extension sleeve is slidably inserted in the main sleeve, and the extension sleeve is connected to the stop block, the extension sleeve is communicated with the main sleeve, a sliding groove is provided on the side wall of the extension sleeve, and the sliding groove passes through the stop block along the axial direction of the extension sleeve and extends to the side wall of the main sleeve;

[0008] The detection assembly includes a laser rangefinder, a connecting rod and a control ring. The laser rangefinder is slidably matched in the extension tube. The connecting rod is slidably matched with the slide groove. One end of the connecting rod is connected to the laser rangefinder, and the other end of the connecting rod is connected to the inner wall of the control ring. The inner diameter of the control ring is adapted to the outer diameter of the main sleeve.

[0009] The barb unit is installed at one end of the main sleeve away from the extension tube and is used to abut against the surface of the wall.

[0010] The principle and effect of this technical solution:

[0011] 1. By providing sliding grooves on the main sleeve, the extension sleeve and the stop block, the laser rangefinder can slide in the main sleeve or the extension sleeve through the connecting rod. When the wall thickness is small (smaller than the length of the main sleeve), the laser rangefinder can be slid into the main sleeve (the position of the control ring corresponds to the main sleeve at this time), and the control ring and the hook unit are respectively abutted on both sides of the wall to measure the wall thickness. Therefore, the device can detect the thickness of thinner walls without changing the maximum detection thickness, thereby increasing the detection range and enhancing the applicability.

[0012] 2. The anti-rotation block is set so that the slide grooves of the main sleeve and the extension tube can always correspond, that is, the connecting rod can always smoothly drive the laser rangefinder to move in the main sleeve and the extension tube. At the same time, the laser rangefinder slides with the extension tube and the inner diameter of the control ring is adapted to the outer diameter of the main sleeve, which can always ensure the position of the laser rangefinder relative to the telescopic assembly.

[0013] The utility model is further configured as follows: the barb unit includes a driving motor, a driving block, a driving screw and a plurality of driving components spaced apart around the circumference of the main sleeve, the driving motor is installed in the main sleeve, the driving screw is rotatably installed in the main sleeve, and the driving screw is connected to the movable end of the driving motor, the driving block is threadedly sleeved on the driving screw, and the driving block is slidably matched with the main sleeve, a receiving groove is provided on the side wall of the main sleeve, the driving component includes a driving rod, a driving plate and a torsion spring, one end of the driving plate is rotatably installed in the receiving groove, and the driving plate is adapted to the receiving groove, one end of the driving rod is hinged to the driving block, the other end of the driving rod is hinged to the driving plate, and the hinged end of the driving rod and the driving plate can slide relative to the driving plate, one end of the torsion spring is connected to the driving plate, and the other end of the torsion spring is connected to the inner wall of the receiving groove.

[0014] The principle and effect of this technical solution: the driving motor drives the driving screw to rotate, so that the driving screw can drive the driving rod to move, and a crank slider structure is formed between the driving block, the driving rod, and the driving plate. The maximum movement position of the driving plate is also limited by the accommodating slot, so that the driving plate can be stored in the accommodating slot without affecting the main sleeve in and out of the drilling hole, and can also be pressed against the other side of the wall by unfolding, so that the detection component can detect the thickness of the wall. The setting of the torsion spring makes the driving plate tend to unfold by itself, thereby avoiding the rigidity of the driving rod being stuck due to insufficient angle between the driving plate.

[0015] The utility model is further configured as follows: a scale is formed on the side wall of the main sleeve.

[0016] The principle and effect of this technical solution: by setting the scale at the corresponding positions of the slide groove and the receiving groove, after the driving plate abuts against the other side wall, the distance between the driving plate and the bottom of the slide groove can be intuitively read through the scale, which is convenient for the operator to replicate the basic length, so as to avoid inaccurate detection data due to the operator forgetting the basic scale.

[0017] The utility model is further configured as follows: the telescopic assembly also includes a hand grip ring, which is threadedly sleeved on the extension tube and is located at an end of the extension tube away from the main sleeve.

[0018] The principle and effect of the technical solution: the provision of the grip ring enables the user to control the overall position of the telescopic assembly by holding the grip ring.

[0019] The utility model is further configured as follows: a limiting bolt is threadedly inserted on the outer wall of the control ring.

[0020] The principle and effect of the technical solution: through the setting of the limit bolt, the device can be carried by moving the control ring to the bottom of the slide groove so that the connecting rod presses the spring, and then the limit bolt abuts against the side wall of the main sleeve so that the spring has no driving force on the extension tube, so that the extension tube can be stored in the main sleeve to the greatest extent. During detection, the limit bolt can be locked on the outer wall of the main sleeve or the extension tube, so that the control ring and the barb unit abut against both sides of the wall together, and then there is no need to pull the extension tube manually, saving manpower.

[0021] The utility model is further configured as follows: a spring is installed in the main sleeve, and the spring is located at a side of the anti-rotation block away from the extension tube.

[0022] The principle and effect of this technical solution: by setting the spring, the limit bolt contacts and abuts against the outer wall of the main sleeve, and the anti-rotation block is driven by the rebound force of the spring to drive the extension tube away from the main sleeve, thereby automatically opening the telescopic assembly, so as to facilitate the opening of the telescopic assembly.

[0023] The utility model is further configured as follows: the outer wall of the control ring is provided with a control button.

[0024] The principle and effect of the technical solution: by arranging the control button on the control ring, the control of the barb unit and the laser rangefinder is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

The hand grip ring 106 is threadedly mounted on the extension tube 102 and is located at the end of the extension tube 102 away from the main sleeve 101. A spring 107 is installed in the main sleeve 101, and the spring 107 is located on the side of the anti-rotation block 103 away from the extension tube 102, and abuts against the end of the anti-rotation groove close to the drive motor 301.

[0038] The detection component includes a laser rangefinder 201, a connecting rod 202 and a control ring 203.
