Description

Technical Field

[0001] This utility model belongs to the field of telescope technology, and in particular relates to a support frame for a smoke measuring telescope. Background Technology

[0002] With increasingly stringent environmental regulations and the deepening of air pollution control efforts, accurate monitoring of industrial flue gas emissions has become crucial. As a direct and efficient device for monitoring the opacity of flue gas, smoke measuring telescopes are widely used by environmental monitoring departments and enterprises in their environmental self-inspections. The accuracy of their observation results directly affects the determination of emission compliance and the effectiveness of supervision. In the actual use of smoke measuring telescopes, the support frame, as a key component for bearing and positioning the equipment, directly determines the accuracy of the observation angle and the clarity of the image.

[0003] However, the existing support frame is not convenient to store and fold during use. During transportation, because the bottom of the support frame needs a large enough area to provide stable support for the smoke measuring telescope, it occupies a lot of space, which affects the portability of the support frame and makes it difficult to carry and store. Utility Model Content

[0004] The purpose of this utility model is to provide a support frame for a smoke measuring telescope. By setting a folding support part, the existing support frames are not convenient to store and fold during use. During transportation, the bottom of the support frame needs a large enough area to provide stable support for the smoke measuring telescope, which occupies a lot of space and affects the portability of the support frame, making it difficult to carry and store.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a support frame for a smoke measuring telescope, including an adjustment box and a placement platform fixedly connected to the top of the adjustment box, and further including: a folding support part, which is disposed on the adjustment box; and a locking part, which is disposed inside the adjustment box and extends to the outside of the adjustment box; wherein, the folding support part is located at the bottom of the adjustment box and extends inside the adjustment box.

[0007] Furthermore, the folding support includes an adjustment component installed at the bottom of the adjustment box; and a hinge component disposed below the adjustment box; wherein, a plurality of hinge components are provided, and the plurality of hinge components are arranged in a circular array around the adjustment box.

[0008] Furthermore, the locking part includes an engaging component disposed inside the adjusting box; and a latching component disposed on the inner wall of the adjusting box; wherein both the engaging component and the latching component extend outside the adjusting box.

[0009] Furthermore, the adjustment assembly includes a cylindrical shell fixedly connected to the bottom of the adjustment box. A threaded rod is rotatably connected to the inner wall of the bottom of the cylindrical shell, and a bracket is fixedly connected to the outer wall of the cylindrical shell. A ring is threadedly connected to the outer wall of the threaded rod. The outer wall of the ring is slidably connected to the inner wall of the cylindrical shell. Six rectangular grooves are formed on the outer wall of the cylindrical shell. The top of the threaded rod extends into the adjustment box and is rotatably connected thereto. The rotation of the threaded rod drives the ring to move up and down, thereby driving the hinge rod of the hinge assembly to rotate, realizing the unfolding or folding of the support rod to adjust the support state of the support frame and meet the usage needs in different scenarios.

[0010] Furthermore, the hinge assembly includes two hinge blocks 1 disposed on the cylindrical shell. Each hinge block 1 has a hinge rod hinged to its side away from the cylindrical shell, and each hinge rod has a hinge block 2 hinged to its side away from the cylindrical shell. Support members are disposed on each of the two hinge blocks 2. The upper hinge block 1 is fixedly connected to a bracket, while the lower hinge block 1 extends into the cylindrical shell through a corresponding rectangular groove and is fixedly connected to a ring. The two hinge rods are hinged to each other. The support member includes a support rod disposed on the left side of each hinge block 2, and a guide rail is fixedly connected to the right side of the support rod. The inner wall of the guide rail is slidably connected to the upper hinge block 2, and fixedly connected to the lower hinge block 2. The right side of the support rod is fixedly connected to the guide rail. Through the rotation of the hinge rod and the cooperation of the hinge blocks 1, 2, support rod, and guide rail, the support rod can be unfolded and retracted under the drive of the adjustment assembly, forming a stable support base or a folding storage structure.

[0011] Furthermore, the meshing assembly includes a first bevel gear fixedly connected to the top extension of the threaded rod, a rotating shaft rotatably connected to the inner wall of the adjustment box, and a second bevel gear fixedly connected to the outer wall of the rotating shaft; wherein, the right side of the rotating shaft extends rotatably out of the adjustment box, and the second bevel gear meshes with the first bevel gear. Through the rotation of the rotating shaft, the power is transmitted to the threaded rod by the meshing transmission of the first bevel gear and the second bevel gear, causing it to rotate and drive the adjustment assembly to work, thereby realizing the adjustment of the unfolding and folding of the folding support.

[0012] Furthermore, the latching assembly includes a rectangular block fixedly connected to the inner wall of the adjustment box, a cylindrical slide rod passing through the rectangular block, a circular block fixedly connected to the outer wall of the cylindrical slide rod, a locking block fixedly connected to the front side of the cylindrical slide rod, and a spring fixedly connected between the rectangular block and the circular block. The locking block is adapted to a bevel gear, the rear side of the cylindrical slide rod slides out of the adjustment box, and the rectangular block and the cylindrical slide rod are slidably connected. Locking or unlocking the meshing assembly is achieved by engaging or disengaging the locking block with the bevel gear. When the locking block engages the bevel gear, it prevents the threaded rod from rotating, thereby fixing the unfolded or folded state of the folding support and ensuring the stability of the support frame during use. When adjustment of the support structure is required, pulling the cylindrical slide rod backward separates the locking block from the bevel gear, unlocking and allowing adjustment.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting up a folding support section, when the folding support section is opened, the locking part is unlocked and the rotating shaft is rotated. The rotating shaft drives the threaded rod to rotate through bevel gear two and bevel gear one. The threaded rod drives the ring to rise, and the ring drives the corresponding hinge block one to rise, thereby driving the two hinged rods that are hinged to each other to rotate. This causes the upper hinge block two to move away from the lower hinge block two under the guidance of the guide rail, thereby driving the support rod away from the cylindrical shell. The support rods of several hinge components move away from the cylindrical shell at the same time. After the distance between several support rods reaches the required distance, the locking part is locked, thus achieving the effect of opening the folding support section. Conversely, rotating the threaded rod in the opposite direction can fold and retract several support rods. The device can be folded during transportation, reducing the space occupied by the support frame, making it convenient to carry and store, thereby improving the portability of the support frame. When unfolded, it can provide a stable support base for the smoke measuring telescope, increasing the contact area with the ground and improving the stability of the support frame.

[0015] 2. By setting a locking part, when unlocking the locking part, pull the cylindrical slide rod backward, causing it to move the locking block away from the first bevel gear. During this process, the circular block moves backward with the cylindrical slide rod and compresses the spring until the locking block separates from the first bevel gear. The first bevel gear can then transmit power normally, and the locking part is released. When the cylindrical slide rod is released, the spring rebounds and, through the circular block, causes the locking block to re-lock onto the first bevel gear, thus completing the locking of the locking part. After the folding support part is unfolded or folded to a suitable position, it is fixed to prevent the folding support part from moving or deforming due to unexpected factors during use, thereby ensuring that the support frame is always in a stable working state.

[0028] A specific application of this embodiment is as follows: In use, when the folding support part 2 is opened, the locking part 3 is unlocked and the rotating shaft 312 is rotated. The rotating shaft 312 drives the threaded rod 212 to rotate through the bevel gear 213 and the bevel gear 1 311. The threaded rod 212 drives the ring 214 to rise, and the ring 214 drives the corresponding hinge block 1 221 to rise, thereby driving the two hinged rods 222 to rotate. This causes the upper hinge block 223 to move away from the lower hinge block 223 under the guidance of the guide rail 225, thereby driving the support rod 224 away from the cylindrical shell 211. The support rods 224 of several hinge components 22 move away from the cylindrical shell 211 at the same time. When the several support rods 224 are in contact with each other... Once the required distance is reached, locking part 3 is locked, thus achieving the effect of opening the folding support part 2. Conversely, rotating the threaded rod 212 in the opposite direction can fold and retract several support rods 224. When unlocking locking part 3, the cylindrical slide rod 322 is pulled backward, causing it to move the locking block 324 away from the bevel gear 311. During this process, the circular block 323 moves backward with the cylindrical slide rod 322 and compresses the spring 325 until the locking block 324 separates from the bevel gear 311. The bevel gear 311 can then transmit power normally, and the locking part 3 is released. When the cylindrical slide rod 322 is released, the spring 325 rebounds and, through the circular block 323, causes the locking block 324 to re-lock onto the bevel gear 311, thus completing the locking of locking part 3.
