Description

Technical Field

[0001] This utility model relates to the field of tilt sensor technology, specifically a small single-axis tilt sensor. Background Technology

[0002] A single-axis tilt sensor is a widely used tilt-assist sensing instrument in ships, construction machinery, automobiles, and rail transportation. It is capable of independent operation and provides good information feedback, used to detect the tilt angle of objects. Single-axis sensors can be installed in various ways, either vertically or horizontally. Regardless of the installation method, it is essential to ensure that the single-axis sensor is parallel to the surface of the object being measured. This is typically achieved using screws and a bracket to fix the sensor to the measured plane, making subsequent maintenance and disassembly of the single-axis sensor somewhat inconvenient. Furthermore, a slight tilt is inevitable after installation, and it is difficult to level the fixed sensor, which can affect the accuracy of subsequent angle detection data.

[0003] Based on the above problems, the existing authorized patent, publication number CN221685494, discloses a single-axis sensor for detecting the tilt angle of an object. It includes a sensor body, a sensor housing fitted over the sensor body, and a sensor base located below the sensor housing. After the sensor body and sensor housing are installed, two adjusting screws can be rotated to raise or lower two adjusting blocks. As the two adjusting blocks move within the movable slots, the angle of the mounting plate is adjusted, achieving a leveling effect between the sensor body and the sensor housing, ensuring the accuracy of the subsequent detection of the object's tilt angle by the sensor body.

[0004] However, the aforementioned disclosed patents have the following inconveniences in practical use. First, the disclosed technology only supports unidirectional leveling of the sensor, limiting its applicability. The leveling structure is based on a "unidirectional rotation of the mounting plate around the axis" design, which can only handle the tilt of the mounting surface in a single direction, such as only being able to swing and adjust in the "left" or "right" direction. If the mounting surface of the object to be detected has tilts in multiple directions, such as "front and back" and "left and right", the leveling structure cannot be adapted, losing the flexibility of the leveling function, and its applicability is limited to environments where the mounting surface is tilted in only one direction.

[0005] Secondly, the disclosed technology adopts a leveling structure of "dual adjusting screws driving the adjusting blocks separately". When leveling, the two adjusting screws need to be manually rotated separately. If the rotation angle and force of the two screws are inconsistent when manually adjusting at the same time, the two adjusting blocks will rise and fall asynchronously, which will cause the mounting plate to tilt and deviate. Repeated calibration is required, which is inconvenient. Therefore, it is necessary to develop a small single-axis tilt sensor. Utility Model Content

The shaft of the first rotating shaft is fixed to the lower end of the adjusting block. A second rotating shaft is fixed to the upper end of the adjusting block. A first side plate is symmetrically mounted on the front and rear ends of the second rotating shaft via bearings. A second side plate is rotatably mounted through the front and rear inner walls of the fixing seat via bearings. The three rotating shafts are parallel to each other and located above the guide slide rod, perpendicular to it. The front and rear ends of the third rotating shaft are fixedly provided with second side plates. The tops of the two first side plates and the two second side plates are jointly fixedly provided with a mounting plate. The two first side plates and the two second side plates are respectively fixed at the four bottom corners of the mounting plate. The upper and lower side walls of the mounting plate have mounting openings. A transverse rotating rod is rotatably inserted through the center of the inner side wall of the mounting opening. A connecting plate is fixedly provided on the inner side of the mounting opening of the rotating rod. The sensor body is installed on the top of the connecting plate.

[0010] The first adjustment mechanism is mounted on the fixed base and the fixed frame, and is used to drive the adjustment frame to slide along the axial direction of the guide slide rod and to lock it.

[0011] The second adjustment mechanism is located on the rotating rod and the mounting plate, and is used to drive the connecting plate to rotate around the rotating rod as an axis and to lock it.

[0012] In a preferred embodiment of the small single-axis tilt sensor described in this utility model, the fixing plate is rectangular and has mounting holes at its four corners.

[0013] In a preferred embodiment of the small single-axis tilt sensor described in this utility model, the outer shell of the sensor body is detachably connected to the top of the connecting plate, and the outer shell of the sensor body is installed to the top of the connecting plate by bolts.

[0014] As a preferred embodiment of the small single-axis tilt sensor described in this utility model, the first adjustment mechanism includes a first transverse drive rod that rotates through the middle of the side wall of the fixed seat and the fixed frame via a bearing. A self-locking threaded rod coaxial with itself is fixedly provided on the rod body of the first drive rod. The rod body of the self-locking threaded rod is screwed through the center of the side wall of the adjustment frame. Two guide slide rods are arranged symmetrically about the self-locking threaded rod.

[0015] In a preferred embodiment of the small single-axis tilt sensor described in this utility model, a first knob is fixedly provided at the right end of the first drive rod, and anti-slip texture is provided on the outer side of the first knob.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. Through the coordinated action of dual adjustment mechanisms, multi-faceted tilt calibration of the sensor is achieved. Specifically, the first adjustment mechanism moves the mounting plate to adjust the tilt angle and adapt to the tilt deviation of the mounting surface in that direction; the second adjustment mechanism can also rotate the connecting plate to directly adjust the tilt angle of the sensor. This bidirectional leveling design can adapt to scenarios where the mounting surface is tilted in multiple directions, expanding the applicable range of sensor installation.

The design of controlling unidirectional adjustment through a single drive source means that the first adjustment mechanism drives the adjustment frame with only one self-locking threaded rod. Rotating the first knob can achieve smooth sliding of the adjustment frame without the need to adjust multiple screws, thus improving adjustment efficiency. Attached Figure Description

[0034] A small single-axis tilt sensor includes a fixed plate 100, a first adjustment mechanism 200, and a second adjustment mechanism 300;

[0035] A U-shaped fixing seat 101 is fixedly installed on the left side of the top of the fixing plate 100, and a fixing frame 102 is fixedly installed on the right side. Two horizontal guide slide rods 103 are symmetrically fixed between the fixing seat 101 and the fixing frame 102. A U-shaped adjusting frame 104 is slidably mounted on the rods of the two guide slide rods 103. A first rotating shaft 105 is rotatably mounted between the front and rear inner walls of the adjusting frame 104 via bearings. The rod of the first rotating shaft 105 is fixed to the lower end of the adjusting block 106. A second rotating shaft 107 is fixed to the upper end of the adjusting block 106. A first side plate 108 is symmetrically mounted on the front and rear ends of the second rotating shaft 107 via bearings. A third rotating shaft 109 is rotatably mounted through the front and rear inner walls of the fixing seat 101 via bearings. The first rotating shaft 105, the second rotating shaft 107, and the third rotating shaft 109 are parallel to each other and located above the guide slide rod 103 and perpendicular to the guide slide rod 103. The front and rear ends of the third rotating shaft 109 are fixedly provided with second side plates 110. The tops of the two first side plates 108 and the two second side plates 110 are jointly fixedly provided with a mounting plate 111. The two first side plates 108 and the two second side plates 110 are respectively fixed at the four bottom corners of the mounting plate 111. The upper and lower side walls of the mounting plate 111 have mounting openings 112. A transverse rotating rod 113 is rotatably passed through the center of the inner side wall of the mounting opening 112. The rod body of the rotating rod 113 is fixedly provided with a connecting plate 114 located inside the mounting opening 112. The top of the connecting plate 114 is equipped with a sensor body 115.

[0036] The first adjustment mechanism 200 is disposed on the fixed base 101 and the fixed frame 102, and is used to drive the adjustment frame 104 to slide along the axial direction of the guide slide rod 103 and to lock it.

[0037] The second adjustment mechanism 300 is disposed on the rotating rod 113 and the mounting plate 111, and is used to drive the connecting plate 114 to rotate around the rotating rod 113 as an axis and to lock it.

[0038] Furthermore, the fixing plate 100 is rectangular in shape, and mounting holes 116 are provided at its four corners. The mounting holes 116 facilitate the fixing of the entire device to the target location, improving the ease of sensor installation.

[0039] Furthermore, the outer shell of the sensor body 115 is detachably connected to the top of the connecting plate 114. The outer shell of the sensor body 115 is installed on the top of the connecting plate 114 by bolts 117. At least two bolts 117 are provided and symmetrically installed on the outer shell of the sensor body 115 and the connecting plate 114. The use of at least two symmetrically installed bolts 117 to achieve the installation of the two facilitates the later disassembly, maintenance or replacement of the sensor body 115, reducing the difficulty of sensor maintenance operations.

[0040] Furthermore, the first adjustment mechanism 200 includes a first drive rod 201 that rotates through the middle of the side wall of the fixed seat 101 and the fixed frame 102 via a bearing. A self-locking threaded rod 202 coaxial with itself is fixedly mounted on the rod body of the first drive rod 201. The rod body of the self-locking threaded rod 202 is screwed through the center of the side wall of the adjustment frame 104. Two guide slide rods 103 are symmetrically arranged about the self-locking threaded rod 202. By rotating the first drive rod 201, the self-locking threaded rod 202 is driven to rotate, thereby driving the adjustment frame 104 to slide smoothly along the axial direction of the guide slide rods 103. The self-locking threaded rod 202's characteristics are used to lock the position of the adjustment frame 104, ensuring the stability of the adjustment frame 104 after adjustment.

[0041] Furthermore, a first knob 203 is fixedly provided at the right end of the first drive rod 201, and the outer side of the first knob 203 is provided with anti-slip texture. The first knob 203 facilitates the operator to manually rotate the first drive rod 201 and reduces hand slippage during rotation, thereby improving the ease of operation of the first adjustment mechanism 200.

[0042] Furthermore, the right end of the rotating rod 113 is located on the right side of the mounting plate 111. The second adjustment mechanism 300 includes a worm gear 301 fixed to the right end of the rotating rod 113. A bracket 302 is fixedly installed on the right side of the mounting plate 111. A second drive rod 303 is rotatably connected to the side wall of the bracket 302 via a bearing. A worm 304 coaxial with itself is fixedly installed on the body of the second drive rod 303. The worm 304 meshes with the worm gear 301, and the lead angle of the worm 304 is smaller than the equivalent friction angle between the teeth of the meshing worm gear 301. By rotating the second drive rod 303, the worm 304 is driven to rotate, which in turn drives the worm gear 301 and the rotating rod 113 to rotate, thereby realizing the rotation of the connecting plate 114 around the rotating rod 113. The self-locking characteristic of the worm gear is used to lock the angle of the connecting plate 114, which helps to finely adjust and stably maintain the tilt angle of the sensor body 115.

[0043] Furthermore, a second knob 305 is fixedly mounted on one end of the second drive rod 303, and the outer side of the second knob 305 is provided with anti-slip texture. The second knob 305 facilitates manual rotation of the second drive rod 303 by the operator and reduces hand slippage during rotation, thereby improving the ease of operation of the second adjustment mechanism 300.

[0044] It should be noted that the first adjustment mechanism 200 proposed in this utility model can also be other devices with the function of driving the adjustment frame 104 to slide along the axial direction of the guide slide rod 103 and locking.

[0045] The proposed second adjustment mechanism 300 can also be other devices that have the function of driving the connecting plate 114 to rotate around the rotating rod 113 and locking.

[0046] When using this device, an angle measuring instrument, such as a slope measuring instrument, can be used to first measure the angle of the mounting surface of the object to be tested. Then, after installing this device on the mounting surface of the object to be tested, the angle of the connecting plate 114 can be adjusted according to the angle of the mounting surface to make the single-axis sensor parallel to the surface of the object being tested. Subsequently, the angle between the mounting surface of the object to be tested and the connecting plate 114 can be measured periodically to adjust the angle of the connecting plate 114 accordingly. In addition, the power supply of the sensor must be disconnected before adjusting the sensor to avoid signal erroneous output during the leveling process.

[0047] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
