Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering measurement technology, specifically a laser rangefinder for building engineering inspection. Background Technology
[0002] A laser rangefinder is an instrument that measures the distance to a target by modulating a specific parameter of a laser beam. Based on the ranging method, they are divided into phase-based rangefinders and pulse-based rangefinders. A pulse-based laser rangefinder emits a single or a series of short pulsed laser beams towards the target. A photoelectric element receives the reflected laser beam, and a timer measures the time from emission to reception to calculate the distance from the observer to the target. A phase-based laser rangefinder measures distance by detecting the phase difference between the emitted and reflected light as they propagate through space.
[0003] Laser rangefinders are typically mounted on a bracket, which is then placed on the ground for use. However, existing brackets lack a limiting mechanism at the bottom. If the outdoor ground is slippery, the bracket may lose its grip, causing it to wobble and affecting the rangefinder's measurement results. Therefore, we need a laser rangefinder for building engineering inspection. Utility Model Content
[0004] The purpose of this invention is to provide a laser rangefinder for building engineering inspection, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser rangefinder for building engineering inspection, comprising a support base, a rangefinder mounted on the support base, a mounting base fixedly mounted on the bottom wall of the support base, a support frame hinged inside the mounting base, a stabilizing mechanism inside the support frame, and a limiting mechanism on the outer walls of the support frame and the support base, the stabilizing mechanism comprising:
[0006] A rotating rod, which is rotatably connected to the inner wall of the support frame;
[0007] A bending plate, which is fixedly installed on the outer wall of the rotating rod, and the bending plate is configured to be bent.
[0008] An insert rod is fixedly installed on the outer wall of the bent plate, and the end of the insert rod is set in a pointed shape.
[0009] Preferably, the outer wall of the rotating rod is fixedly connected to one end of the torsion spring, and the other end of the torsion spring is fixedly connected to the inner wall of the support frame.
[0010] Preferably, a guide roller is rotatably connected to the inner wall of the support frame, and a pull rope is wound on the guide roller. One end of the pull rope is fixedly connected to the outer wall of the bending plate, and the other end of the pull rope is fixedly connected to the bottom wall of the mounting base.
[0011] Preferably, the limiting mechanism includes an elastic plate, which is fixedly installed on the bottom wall of the support base, and the elastic plate is configured in an arc shape.
[0012] Preferably, a locking block is fixedly installed on the outer wall of the elastic plate, and one side of the locking block is set in an arc shape.
[0013] Preferably, a fixing plate is fixedly installed on the outer wall of the support frame, and a slot is provided on the fixing plate, the slot being adapted to the size of the locking block.
[0014] Compared with the prior art, this utility model provides a laser rangefinder for building engineering inspection, which has the following beneficial effects:
[0015] 1. The laser rangefinder for building engineering inspection uses a stabilizing mechanism to pull the end of the curved plate by pulling the rope, which causes the curved plate to rotate around the rotating rod. The curved plate drives the insert rod on the outer wall to rotate out of the support frame and insert into the ground, which makes the support frame more stable and prevents deviation.
[0016] 2. The laser rangefinder for building engineering testing is engaged with the slot in the limiting mechanism, which can stably support the position of the support frame and facilitate the use of the rangefinder. At the same time, by pushing the elastic plate to move the locking block out of the slot, the limiting can be released, making it easy to store the support frame. Attached Figure Description

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a laser rangefinder for building engineering inspection, including a support base 1, a rangefinder 2 mounted on the support base 1, an mounting base 3 fixedly mounted on the bottom wall of the support base 1, a support frame 4 hinged inside the mounting base 3, which can be opened for use by pushing the support frame 4, a stabilizing mechanism 5 is provided inside the support frame 4, and a limiting mechanism 6 is provided on the outer wall of the support frame 4 and the support base 1.
[0023] In this embodiment, a stabilizing mechanism 5 is provided inside the support frame 4. By pulling the end of the bent plate 52 through the pull rope 56 in the stabilizing mechanism 5, the bent plate 52 can be rotated around the rotating rod 51. The bent plate 52 drives the insertion rod 53 on the outer wall to rotate out of the support frame 4 and insert into the ground, which can make the support of the support frame 4 more stable and prevent displacement.
[0024] In this embodiment, a limiting mechanism 6 is provided on the outer wall of the support frame 4 and the support base 1. The locking block 62 in the limiting mechanism 6 is engaged into the inside of the slot 64, which can stably support the position of the support frame 4, making it convenient to use the rangefinder 2. At the same time, by pushing the elastic plate 61 to move the locking block 62 out of the inside of the slot 64, the limiting can be released, making it convenient to store the support frame 4.
[0025] The aforementioned stabilizing mechanism 5 includes a rotating rod 51, which is rotatably connected to the inner wall of the support frame 4. A bent plate 52 is fixedly installed on the outer wall of the rotating rod 51. By pulling the end of the bent plate 52 with a rope 56, the bent plate 52 can rotate around the rotating rod 51. An insert rod 53 is fixedly installed on the outer wall of the bent plate 52. The end of the insert rod 53 is pointed. The bent plate 52 drives the insert rod 53 on the outer wall to rotate out of the support frame 4 and insert into the ground, which can make the support of the support frame 4 more stable and prevent displacement. The outer wall of the rotating rod 51 is fixedly connected to one end of a torsion spring 54. The other end of 54 is fixedly connected to the inner wall of the support frame 4. The spring force of the torsion spring 54 can cause the rotating rod 51 to drive the bending plate 52 to rotate and reset. The bending plate 52 pulls the pull rope 56, which can pull the support frame 4 to reset for easy storage. A guide roller 55 is rotatably connected to the inner wall of the support frame 4. A pull rope 56 is wound on the guide roller 55. The rotation of the support frame 4 can make the pull rope 56 taut, which can pull the end of the bending plate 52. One end of the pull rope 56 is fixedly connected to the outer wall of the bending plate 52, and the other end of the pull rope 56 is fixedly connected to the bottom wall of the mounting base 3.
[0026] The aforementioned limiting mechanism 6 includes an elastic plate 61, which is fixedly installed on the bottom wall of the support base 1. The elastic plate 61 is arc-shaped, and a locking block 62 is fixedly installed on the outer wall of the elastic plate 61. One side of the locking block 62 is arc-shaped. The support frame 4 drives the fixed plate 63 on the outer wall to rotate and squeeze the arc-shaped outer wall of the locking block 62, which can cause the locking block 62 to deform the elastic plate 61 and release the limiting. The support frame 4 is fixedly installed on the outer wall, and the fixed plate 63 has a slot 64. The slot 64 is adapted to the size of the locking block 62. The elastic force of the elastic plate 61 can make the locking block 62 engage with the inside of the slot 64. By engaging the position of the support frame 4, stable support can be provided, which is convenient for the use of the rangefinder 2.
[0027] In this embodiment, during use, the support frame 4 is pushed to open it. During this opening process, the rotation of the support frame 4 tightens the pull rope 56, which in turn pulls the end of the bent plate 52, causing it to rotate around the rotating rod 51. The bent plate 52 then rotates the insert rod 53 on the outer wall out of the support frame 4, allowing it to insert into the ground, thus stabilizing the support frame 4 and preventing displacement. Simultaneously, the support frame 4 drives the fixing plate 63 on the outer wall to rotate, which in turn presses against the outer wall of the locking block 62. The pressure on the arc-shaped outer wall of the locking block 62... The locking block 62 causes the elastic plate 61 to deform, releasing the limit. Then, the elastic force of the elastic plate 61 causes the locking block 62 to engage inside the slot 64. At the same time, the elastic force of the torsion spring 54 keeps the support frame 4 in place for stable support, facilitating the use of the rangefinder 2. When the support frame 4 needs to be stored, the elastic plate 61 is pushed to move the locking block 62 out of the slot 64, releasing the limit. Then, the elastic force of the torsion spring 54 causes the rotating rod 51 to rotate and reset the bending plate 52. Then, the bending plate 52 pulls the pull rope 56, resetting the support frame 4. The support frame 4 is then stored for easy transport.
[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
