[0002] In many fields such as industrial production, environmental monitoring, and biomedical testing, small instruments and meters have been widely and importantly used due to their small size, portability, ease of operation, and high-precision measurement capabilities. The core structure of the instrument and meter consists of four parts: the front end is the sensor, which converts the measured temperature, voltage, etc. into electrical signals; the middle is the processing unit, which processes the signals and removes interference; next is the display or output module, which presents the results or transmits data; and then there are auxiliary components such as the power supply and the housing. All parts work together to realize the detection or control function.

[0003] However, most traditional small instruments rely on bolt installation, which is a fixed structure with poor adaptability. They cannot be compatible with mounting carriers of different thicknesses or shapes, and the angle adjustment is limited. Some instruments have no angle adjustment function or can only be adjusted in one direction. Operators need to frequently adjust their own position to read data, which makes them inconvenient to use. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 and Figure 2This utility model provides an embodiment of a small instrument that is easy to fix, including an instrument housing 1, which houses the instrument's display screen, measuring elements, circuit modules and other functional components, providing physical protection for the internal components to prevent damage to the internal structure from external dust, moisture or minor collisions. It is the basic support carrier for realizing angle adjustment and clamping fixation functions. A rotating component 2 is fixedly connected to the lower side of the instrument housing 1, which can realize multi-angle adjustment and locking of the instrument housing 1 to meet the needs of different observation angles. A clamping component 3 is fixedly connected to the lower side of the rotating component 2, which can realize the instrument's adaptation and fixation with mounting carriers of different thicknesses and shapes.

[0036] Reference Figure 2 , Figure 3 and Figure 5 The rotating assembly 2 includes a connecting plate A21 for connecting the rotating assembly 2 to the instrument housing 1. The connecting plate A21 is fixedly connected to the lower side of the instrument housing 1 by a fixing bolt 22. The fixing bolt 22 passes through the connecting plate A21 and is threaded to the lower side of the instrument housing 1, ensuring the connection stability between the rotating assembly 2 and the instrument housing 1. A sleeve 23, the core linkage component of the rotating assembly 2, is fixedly connected to the lower side of the connecting plate A21. The upper side is fixed to the connecting plate A21, and the lower side is inserted into the connector 24. The sleeve 23 has protrusions 231 evenly arranged inside. By inserting into the slot A27 of the connector 24, the relative rotation of the sleeve 23 and the connector 24 is restricted. The protrusions 231 and the slot A27 are inserted to realize the angle locking and unlocking of the instrument. A connector 24 is inserted into the lower side of the sleeve 23. The connector 24 is set in a T-shape and is used to connect the rotating assembly 2 to the clamp. The transition connection component of the fastening assembly 3 has an elastic element 28 elastically connected to the upper side of the connector 24. This pushes the sleeve 23 downward, causing the protrusion 231 to stably engage with the slot A27. When the instrument housing 1 is moved upward to adjust the angle, the elastic element 28 is compressed and stores force. After being released, it is reset by the elastic force, ensuring that the protrusion 231 is locked back into the slot A27. The lower outer arc surface of the upper part of the connector 24 is evenly provided with slots A27. The slots A27 are arc-shaped and are inserted into the sleeve 23. Each slot A27 corresponds to a fixed angle. By inserting the protrusion 231 into different slots A27, multi-angle positioning of the instrument housing 1 can be achieved. The connector 24 is connected to a fixing block 25 by an adjusting bolt A26. This is an intermediate structure connecting the rotating assembly 2 and the clamping assembly 3. The adjusting bolt A26 passes through the fixing block 25 and is threaded to the inner wall of the connector 24 to connect the connector 24 and the fixing block 25, preventing them from loosening during rotation.

[0037] Reference Figure 4 , Figure 6 and Figure 7The clamping assembly 3 includes a connecting plate B31, which is the basic fixing component of the clamping assembly 3. Both the connecting plate B31 and the connecting plate C33 are L-shaped, forming a C-shape to facilitate clamping of the mounting carrier. The connecting plate B31 is fixedly connected to the lower side of the fixing block 25. Two sets of limiting posts 32 are fixedly connected to the outer side of the connecting plate B31. The outer diameter of the two sets of limiting posts 32 is larger than that of the other side, and they cooperate with the sliding groove 34 of the connecting plate C33 to prevent them from falling off during sliding. The outer side of the two sets of limiting posts 32 is slidably connected to the connecting plate C33 through the sliding groove 34. The sliding groove 34 consists of a vertically opened sliding groove and four L-shaped slots. The two sets of limiting posts 32 are slidably connected to the inner wall of the sliding groove 34. The two sets of limiting posts 32 slide up and down through the vertically opened sliding groove, thereby driving the connecting plate B31 to move, and then the two The limiting posts 32 slide into the L-shaped slots of the sliding groove 34 to limit and fix the connecting plate B31. The lower side of the connecting plate C33 is threaded with an adjusting bolt B35. By rotating the adjusting bolt B35, the locking block 36 moves up and down. The upper side of the adjusting bolt B35 is rotatably connected to the locking block 36. The rotation of the adjusting bolt B35 drives the locking block 36 to move, so that the locking block 36 cooperates with the connecting plate B31 to clamp and loosen the installation carrier. The upper side of the connecting plate B31 and the upper side of the locking block 36 are both horizontally provided with a locking groove B361. The locking groove B361 is arc-shaped to facilitate clamping cylindrical installation carriers. The upper side of the connecting plate B31 and the upper side of the locking block 36 are both vertically provided with a locking groove C362. The locking groove C362 is circular to facilitate clamping spherical installation carriers.

[0038] Working principle: During use, based on the thickness of the mounting carrier, push the connecting plate C33 along the vertical sliding groove of the sliding groove 34 by the limiting post 32 on the outer side of the connecting plate B31 until the relative distance between the connecting plate B31 and the connecting plate C33 is slightly greater than the thickness of the carrier. Then, slide the limiting post 32 into the L-shaped slot of the sliding groove 34 to restrict the downward movement of the connecting plate C33. Then, based on the shape of the carrier edge, if the carrier is rectangular, make the carrier edge fit against the upper side of the connecting plate B31 and the upper side of the clamping block 36; if the carrier is cylindrical, make the carrier edge fit against the horizontal clamping groove B361 on the upper side of the connecting plate B31 and the clamping groove B361 on the upper side of the clamping block 36; if the carrier is spherical, make the carrier edge fit against the clamping groove C362 of the connecting plate B31 and the clamping block 36. Then, rotate the adjusting bolt B35 to push the bolt upwards to clamp the clamping block 36 with the connecting plate B31 to install the carrier, thus completing the fixed installation of the instrument.

[0039] After fixing, if it is necessary to adjust the observation angle of the instrument housing 1, move the instrument housing 1 upward, causing the connecting plate A21 and the sleeve 23 to move upward synchronously, so that the protrusion 231 inside the sleeve 23 disengages from the arc-shaped slot A27 of the connector 24. At this time, the elastic element 28 is compressed. Then rotate the instrument housing 1, and drive the connector 24 to rotate synchronously through the sleeve 23 until the required observation angle is adjusted. Then release the instrument housing 1, and the elastic element 28 will elastically reset, pushing the sleeve 23 downward, so that the protrusion 231 re-engages with the slot A27 of the corresponding position of the connector 24, thereby completing the angle locking and meeting the reading angle or multi-directional monitoring needs of different operators.

[0040] If the instrument needs to be disassembled, first rotate the adjusting bolt B35 to move the locking block 36 downwards and release it from the carrier, thus releasing the clamping state. Then slide the connecting plate C33 along the vertical section of the sliding groove 34 to remove the instrument.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
