Description

Technical Field

[0001] The utility model relates to the technical field of laser gas detector installation, in particular to a fixing adjustment mechanism for a laser gas detector. Background Art

[0002] Laser gas detector is a new type of environmental detector that can be used to detect the concentration of methane and other substances in the near-ground atmosphere. Its advantages are fast and accurate detection, no need to contact the material to be tested, and no need to add any reagents, thus becoming a must-have for safety prevention and control work in the field of environmental protection.

[0003] After searching, the patent document with authorization announcement number CN215218542U discloses a vehicle-mounted laser methane detection device, which includes: a shock absorbing mechanism and a locking mechanism; the locking mechanism is rotatably installed on the top of the shock absorbing mechanism; the shock absorbing mechanism is fixed on the vehicle body and supports the laser methane detector, so that the impact force exerted on the laser methane detector is relieved by the shock absorbing mechanism, and at the same time, the shock absorbing mechanism squeezes the bottom of the locking mechanism, so that the locking mechanism can clamp the laser methane detector and relieve the squeezing force exerted on the locking mechanism by the shock absorbing mechanism, so that the locking mechanism releases the laser methane detector.

[0004] In the above device, the locking function and the shock absorbing function of the laser methane detector are realized respectively by setting the locking mechanism and the shock absorbing mechanism. In the use of the laser gas detector, angle adjustment is particularly important, because the laser emitted by the laser gas detector is usually in the millimeter level, and a slight deviation will lead to a large deviation in the detection result. When multiple laser gas detectors need to be installed in various parts of the factory, due to the different use angles of the laser gas detectors in various parts of the factory, the above device cannot be used to adjust the laser gas detectors in the installation process at multiple angles, that is, it is impossible to adaptably adjust the corresponding laser gas detector to the required use angle. In the process of adjusting the laser gas detector, the staff generally directly drives the laser gas detector to rotate by hand to adjust the corresponding angle, but due to the staff's hand shaking and other reasons, the laser gas detector cannot be accurately adjusted, or it takes a lot of time to adjust the laser gas detector to the corresponding position. Therefore, this kind of adjustment method that relies solely on manual operation is inconvenient to use.

[0005] To this end, we propose a fixed adjustment mechanism for a laser gas detector to solve the above problems. Utility Model Content

[0013] As a further solution of the utility model: a follower plate that conflicts with the mounting plate is fixedly arranged at the bottom of the limit ring, and a plurality of arc-shaped through holes are arranged in a circumferential array on the follower plate, and a first screw that can be threadedly connected to the mounting plate is arranged on the plurality of arc-shaped through holes.

[0015] As a further solution of the utility model: it also includes a second locking member for locking the vertical part on the rotating plate, the second locking member includes a second screw with one end movably passing through the vertical part and threadedly mounted on the rotating plate, a second through hole for the second screw to pass through is opened on the vertical part, and the rotation of the second screw on the rotating plate can drive its head to move toward the vertical part, so as to realize the second screw's pressing and locking on the vertical part.

[0016] As a further solution of the utility model: second movable rods are movably provided on both sides of the rotating plate and are arranged opposite to each other, and one end of the two second movable rods close to each other respectively contacts one side of the vertical part, so that when the two second movable rods cooperate with each other to feed, the vertical part will be driven to rotate.

[0017] As a further solution of the utility model: a waist-shaped through hole is provided on the vertical portion at a position above the second through hole, and a second screw with one end penetrating the waist-shaped through hole is movably provided on the rotating plate.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figure 1-Figure 10 As shown, a fixed adjustment mechanism for a laser gas detector comprises a mounting plate 1 installed at a corresponding location, an assembly plate 2 for assembling the laser gas detector, and a rotating plate 3 for connecting the mounting plate 1 and the assembly plate 2, wherein: a first through hole 4 is opened on the mounting plate 1 for a rotating portion 5 at the top of the rotating plate 3 to pass through from bottom to top, and the position of the rotating portion 5 on the first through hole 4 is rotatable and adjustable, a retaining ring 7 is engaged with the rotating portion 5, and a regulating rod 8 is integrally formed on the outer side of the retaining ring 7, two first movable rods 10 are movably arranged on the mounting plate 1, which are respectively in conflict with one side of the regulating rod 8, and specifically, vertical plates 9 are arranged on both sides of the regulating rod 8 on the mounting plate 1, and the two first movable rods 10 are arranged relatively and movably arranged on one of the vertical plates 9 respectively. When the two first movable rods 10 cooperate with each other to feed, the regulating rod 8 will be driven to rotate; the assembly plate 2 is rotatably arranged at the bottom end of the rotating plate 3, so that the position between the assembly plate 2 and the rotating plate 3 can be relatively adjusted, and the rotation axis of the assembly plate 2 and the rotation axis of the rotating part 5 are perpendicular to each other.

[0038] During use, when it is necessary to adjust the horizontal angle between the rotating plate 3 and the mounting plate 1, the two first movable rods 10 can be driven to cooperate with each other to feed. The coordinated feeding movement of the two first movable rods 10 can drive the regulating rod 8 to rotate, and then the regulating rod 8 drives the retaining ring 7 and the rotating part 5 to rotate. The rotation of the rotating part 5 can realize the rotation of the rotating plate 3, that is, the horizontal angle between the mounting plate 1 and the rotating plate 3 can be adjusted. Subsequently, by adjusting the position of the assembly plate 2 on the rotating plate 3, the pitch angle of the assembly plate 2 on the rotating plate 3 can be adjusted. Through the joint adjustment of these two methods, the laser gas detector located on the assembly plate 2 can be adjusted in multiple directions, can be adapted to the corresponding use place, and is easy to use.

[0039] like Figure 1-Figure 3 and Figure 7 As shown, for the arrangement where the snap ring 7 is installed on the rotating part 5, a stop ring 6 for engaging and sleeved with the snap ring 7 can be provided on the end of the rotating part 5 that passes through the first through hole 4, so that the snap ring 7 and the stop ring 6 can form a whole and rotate. At the same time, in order to lock the position state of the rotating plate 3 after adjustment on the mounting plate 1, a first locking member for locking the position of the rotating plate 3 can be provided on the mounting plate 1.

[0040] like Figure 1 and Figure 5 As shown, specifically, the first locking member includes a nut 11 sleeved on the rotating portion 5, and the rotating portion 5 is configured as a threaded column adapted to the nut 11, and when the nut 11 moves toward the limiting ring 6 until it contacts the top of the limiting ring 6, the bottom of the limiting ring 6 will be pressed and locked on the mounting plate 1. The locking of the position of the limiting ring 6 will also lock the positions of the snap ring 7 and the rotating plate 3. The locking in this state realizes the position locking between the rotating plate 3 and the mounting plate 1, ensuring that the angle between the rotating plate 3 and the mounting plate 1 can be stably maintained after adjustment. Of course, in order to make the nut 11 have a better locking effect on the limiting ring 6, a gasket 19 can be provided between the limiting ring 6 and the nut 11, and the gasket 19 is used to improve the locking effect.

[0041] like Figure 6 and Figure 8-Figure 9 As shown, on the basis of locking the rotating plate 3 and the mounting plate 1 by the first locking member, in order to better improve the locking effect between the rotating plate 3 and the mounting plate 1, a follower disk 12 can be fixedly arranged at the bottom of the limit ring 6, and the follower disk 12 conflicts with the mounting plate 1, and a plurality of arc-shaped through holes 13 are arranged in a circumferential array on the follower disk 12, and a first screw 14 that can be threadedly connected with the mounting plate 1 is arranged on the plurality of arc-shaped through holes 13. During the adjustment process, the rotation of the limit ring 6 and the snap ring 7 can drive the follower disk 12 to follow, and the rotation of the follower disk 12 can drive the plurality of arc-shaped through holes 13 and the plurality of first screws 14 thereon to rotate. When the adjustment is completed, the first screw 14 can be slid on the arc-shaped through hole 13, and the first screw 14 can be threadedly installed on the threaded hole of the mounting plate 1. At this time, on the basis of locking the rotating plate 3 and the mounting plate 1 by the first locking member, the first screw 14 on the follower disk 12 is threadedly installed on the mounting plate 1 again, which can better improve the locking effect between the rotating plate 3 and the mounting plate 1.

[0042] like Fig.10As shown, further, the assembly plate 2 includes a vertical portion 201 rotatably mounted at the bottom end of the rotating plate 3 and a horizontal portion 202 connected to the vertical portion 201, and the horizontal portion 202 is used to assemble the laser gas detector. At the same time, in order to lock the position state of the assembly plate 2 after adjustment on the rotating plate 3, a second lock for locking the position of the assembly plate 2 can be provided on the rotating plate 3.

[0043] Specifically, the second locking member includes a second screw 15 with one end movably passing through the vertical portion 201 and threadedly mounted on the rotating plate 3. The vertical portion 201 is provided with a second through hole 16 for the end of the second screw 15 to pass through, and the rotation of the second screw 15 on the rotating plate 3 can drive its head to move toward the vertical portion 201 to achieve the pressing and locking of the second screw 15 on the vertical portion 201. Specifically, before the angle between the rotating plate 3 and the assembly plate 2 is adjusted, the vertical portion 201 can move freely. At this time, the pitch angle adjustment between the rotating plate 3 and the assembly plate 2 can be achieved by driving the vertical portion 201 to rotate a corresponding angle; when the second screw 15 is subsequently driven to rotate until the head of the second screw 15 presses on the vertical portion 201, the position between the vertical portion 201 and the rotating plate 3 will be locked, that is, the position between the assembly plate 2 and the rotating plate 3 will be locked, which can ensure the stability of the rotating plate 3 and the assembly plate 2 after the pitch angle adjustment. In order to ensure that the second screw 15 can well lock the vertical portion 201 and the rotating plate 3 , an external nut 20 may be provided on the second screw 15 .

[0044] like Figure 8-Figure 9 As shown, in order to achieve detailed adjustment of the vertical part 201 on the rotating plate 3, second movable rods 18 arranged opposite to each other can be movably provided on both sides of the rotating plate 3, and the two second movable rods 18 are close to each other and respectively contact one side of the vertical part 201, so that when the two second movable rods 18 cooperate with each other to feed, the vertical part 201 will be driven to rotate. By driving the two second movable rods 18 to cooperate with each other to feed, the two sides of the top of the vertical part 201 can be pressed and rotated, so as to achieve the adjustment of the pitch angle of the assembly plate 2.

[0045] Preferably, the two first movable rods 10 and the two second movable rods 18 can be set as threaded rods, so that the two first movable rods 10 and the two second movable rods 18 can be rotated to achieve the coordinated feeding between them. Of course, in actual use, it is not limited to setting the two first movable rods 10 and the two second movable rods 18 as threaded rods, and the two first movable rods 10 and the two second movable rods 18 can also be set as other conventional technical means in the prior art, as long as they can achieve the corresponding coordinated feeding function.

[0046] like Figure 5 and Fig.10As shown, in the process of adjusting the vertical part 201 by the coordinated feeding of the two second movable rods 18, in order to realize smooth and stable rotation of the vertical part 201, a waist-shaped through hole 17 can be opened on the vertical part 201 at a position above the second through hole 16, and a second screw 15 with one end passing through the waist-shaped through hole 17 is movably provided on the rotating plate 3. During the process of adjusting the rotation of the vertical part 201, the position of the second screw 15 on the rotating plate 3 is constant, and the waist-shaped through hole 17 will be driven to rotate during the rotation of the vertical part 201. Since the rotation trajectory circle of the vertical part 201 is coaxial with the arc of the waist-shaped through hole 17, the second screw 15 will limit and guide the waist-shaped through hole 17, thereby ensuring the smoothness and stability of the rotation of the vertical part 201.

[0047] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
