Description

Technical Field

[0001] This utility model relates to the field of illuminance meters, specifically to a rotatable illuminance meter. Background Technology

[0002] An illuminance meter (or lux meter) is an instrument specifically designed to measure illuminance. An illuminance meter typically consists of a probe and a body. However, current illuminance meters do not allow for direct observation of the measured value during measurement; the body needs to be adjusted to view the reading. This causes the probe to shift, affecting the measurement accuracy. Utility Model Content

[0003] In view of this, the present invention provides a rotatable illuminance meter, which can improve the detection accuracy of the illuminance meter.

[0004] This utility model provides the following technical solution:

[0005] A rotatable illuminometer, comprising:

[0006] case;

[0007] A rotating shaft assembly is disposed on the housing. The rotating shaft assembly includes a shaft arm and a driving member. The driving member is disposed inside the housing. The shaft arm extends from inside the housing to the outside of the housing. The driving member is connected to the shaft arm. The driving member is used to drive the shaft arm to rotate circumferentially along the shaft arm.

[0008] A probe is disposed at the end of the shaft arm away from the drive member, and the probe is movably disposed on the shaft arm.

[0009] Furthermore, the shaft arm includes: an extension portion and a connecting portion;

[0010] The extension is fixedly connected to the connecting part, the extension is connected to the driving member, and the connecting part is provided with a through hole penetrating the connecting part.

[0011] Furthermore, the midpoint of the connecting portion is connected to the extension portion, the connecting portion extends from the midpoint of the extension portion to both sides of the extension portion, and both ends of the connecting portion are provided with through holes.

[0012] Furthermore, the curvature of the connecting portion is greater than the curvature of the probe.

[0013] Furthermore, connectors are provided on both sides of the probe, the connectors are fixedly connected to the probe, the connectors are disposed in the through hole, and the connectors are rotatably connected to the shaft arm.

[0014] Furthermore, the shaft arm has a cavity, and a locking mechanism is provided in the cavity. The connecting member is also rotatably disposed in the cavity. The locking mechanism is used to cooperate with the connecting member and restrict the rotation of the connecting member.

[0015] Furthermore, ratchet teeth are provided along the outer periphery of the connector.

[0016] Furthermore, the locking mechanism includes: a fixing member and a telescopic member;

[0017] The fixing member is disposed within the cavity, and the fixing member has a movable hole penetrating through the fixing member. The telescopic member is movably disposed within the movable hole, and the telescopic member is used to engage with the ratchet to restrict the rotation of the connecting member.

[0018] Furthermore, the end of the telescopic member closest to the connecting member is configured as a slope.

[0019] Furthermore, the housing is provided with a protrusion that surrounds the outer periphery of the shaft arm, and the connection between the protrusion and the housing is provided with an arc-shaped chamfer.

[0020] The aforementioned rotatable illuminance meter has a rotating shaft assembly on its housing. The rotating shaft assembly includes a drive component and a shaft arm. The drive component is connected to the shaft arm, enabling the drive component to drive the shaft arm to rotate. This allows the probe mounted on the shaft arm to rotate circumferentially along the shaft arm, thus allowing the probe to rotate axially along the shaft arm. The probe is movably positioned at the end of the shaft arm away from the drive component, allowing it to rotate perpendicular to the circumferential direction of the shaft arm. This allows the probe to rotate in two directions, preventing changes in the probe's position from affecting the measurement accuracy of the rotatable illuminance meter when adjusting the housing position. It significantly improves the probe's rotation range. When measuring the ambient illuminance of the current environment, the housing can be held in a convenient observation position, and the relative position of the probe can be adjusted to align the probe with the light source.

Detailed Implementation

[0029] 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.

[0030] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0031] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] An illuminance meter (or lux meter) is an instrument specifically designed to measure illuminance. An illuminance meter typically consists of a probe and a body. However, current illuminance meters do not allow for direct observation of the measured value during measurement; the body needs to be adjusted to view the reading. This causes the probe to shift, affecting the measurement accuracy.

[0033] Therefore, this embodiment provides a rotatable illuminance meter 100. The rotatable illuminance meter 100 can improve the detection accuracy of the rotatable illuminance meter 100.

[0034] See also Figure 1 and Figure 2 A rotatable illuminance meter 100, comprising:

[0035] Housing 10; Rotating shaft assembly 20, the rotating shaft assembly 20 is disposed on the housing 10, the rotating shaft assembly 20 includes a shaft arm 21 and a driving member 22, the driving member 22 is disposed inside the housing 10, the shaft arm 21 extends from inside the housing 10 to the outside of the housing 10, the driving member 22 is connected to the shaft arm 21, and the driving member 22 is used to drive the shaft arm 21 to rotate circumferentially along the shaft arm 21;

[0036] The probe 30 is disposed at the end of the shaft arm 21 away from the drive member 22, and the probe 30 is movably disposed on the shaft arm 21.

[0037] The aforementioned rotatable illuminance meter 100 has a rotating shaft assembly 20 on its housing 10. The rotating shaft assembly 20 includes a drive member 22 and a shaft arm 21. The drive member 22 is connected to the shaft arm 21, enabling the drive member 22 to drive the shaft arm 21 to rotate. This allows the probe 30, mounted on the shaft arm 21, to rotate circumferentially along the shaft arm 21. This allows the probe 30 to rotate axially along the shaft arm 21. The probe 30 is movably positioned at the end of the shaft arm 21 away from the drive member 22, allowing it to rotate in a direction perpendicular to the circumferential direction of the shaft arm 21. This allows the probe 30 to rotate in two directions, preventing changes in the position of the probe 30 when adjusting the position of the housing 10 from affecting the measurement accuracy of the rotatable illuminance meter 100. This significantly improves the range of rotation of the probe 30. When it is necessary to measure the ambient illuminance of the current environment, the housing 10 can be held in a position that is easy to observe, and the relative position of the probe 30 can be adjusted so that the probe 30 can detect the position of the light. In this way, the illuminance value of the current environment can be observed without adjusting the position of the housing 10, which is not only convenient to use but also improves the measurement accuracy.

[0038] Understandably, the rotating shaft assembly 20 provided on the housing 10 includes a drive member 22 and a shaft arm 21. The drive member 22 is fixedly installed inside the housing 10, while the shaft arm 21 passes through the side wall of one side of the housing 10 and extends to the outside of the housing 10. The drive member 22 is connected to the shaft arm 21, and the probe 30 is mounted on the shaft arm 21 by rotation. In this way, when the drive member 22 rotates, it can drive the shaft arm 21 to rotate, thus enabling the shaft arm 21 to rotate in the left and right directions.

[0039] The probe 30, which is movable on the shaft arm 21, can rotate in the vertical direction of the shaft arm 21, thus greatly increasing the range of motion of the probe 30. When users perform illuminance measurements at different angles and positions, they do not need to frequently adjust the overall position of the equipment, improving the flexibility of measurement.

[0040] See also Figure 2 and Figure 3 In some embodiments, the shaft arm 21 includes: an extension 211 and a connecting portion 212;

[0041] The extension 211 is fixedly connected to the connecting part 212, the extension 211 is connected to the driving member 22, and the connecting part 212 is provided with a through hole 213 penetrating the connecting part 212.

[0042] Understandably, the shaft arm 21 includes an extension 211 and a connecting part 212. The extension 211 and the connecting part 212 are fixedly connected to achieve the overall structural rigidity. The extension 211 is directly connected to the drive component 22, which can stably transmit the driving force to the shaft arm 21, so that the probe 30 maintains high stability during rotation and measurement, reduces shaking or deviation during operation, and ensures the accuracy of measurement.

[0043] Understandably, the extension 211 extends from the inside of the housing 10 to the outside of the housing 10, and the connecting part 212 is used to connect with the probe 30. The connecting part 212 is provided with a through hole 213 that passes through the connecting part 212. Connecting rods can be provided on both sides of the probe 30. By installing the connecting rods into the through hole 213, the probe 30 can rotate on the shaft arm 21. This allows the shaft arm 21 to rotate freely in different directions and adjust the probe 30 to different positions according to user needs, so that the probe 30 can rotate more flexibly, thereby improving the freedom of measurement angle and adapting to more complex measurement scenarios.

[0044] See also Figure 3 In some embodiments, the connecting portion 212 is connected to the extension portion 211 from the midpoint of the connecting portion 212, and the connecting portion 212 extends from the midpoint of the extension portion 211 to both sides of the extension portion 211.

[0045] It is understandable that the midpoint of the connecting part 212 is connected to the extension part 211, that is, the connecting part 212 is connected to the extension part 211 at half position (i.e., the midpoint of the connecting part 212). This allows the weight of the probe 30 to be distributed more evenly on the extension part 211, and also avoids the probe 30 from having a large deviation in its rotation angle when rotating, which would lead to a large measurement error.

[0046] In some embodiments, the connecting portion 212 may be configured as an arc shape, i.e., as shown below. Figure 3 The shape shown can also be set to a square or other shape that can support the probe. Setting it to an arc shape allows the connecting part 212 to protect the probe and also makes the structure of the connecting part more compact.

[0047] See also Figure 3 In some embodiments, the curvature of the connecting portion 212 is greater than the curvature of the probe 30.

[0048] Understandably, because the curvature of the connecting part 212 is greater than that of the probe 30, the probe 30 has a greater range of motion on the connecting part 212. The probe 30 can not only adjust its angle more freely, but also achieve more flexible positioning, thereby improving the adaptability of the rotatable illuminance meter 100 in complex lighting environments, so as to perform measurements at different angles and positions.

[0049] See also Figure 3 In some embodiments, connectors 31 are provided on both sides of the probe 30. The connectors 31 are fixedly connected to the probe 30. The connectors 31 are disposed in the through hole 213 and are rotatably connected to the shaft arm 21.

[0050] Understandably, the connector 31 is fixed on both sides of the probe 30 and is rotatably connected to the shaft arm 21 through the through hole 213, which ensures that the probe 30 can rotate flexibly and remain relatively stable during the measurement process. The rotatable connection between the connector 31 and the through hole 213 provides the probe 30 with additional support and vibration resistance, ensuring that the probe 30 can maintain a relatively stable state when subjected to external impact or vibration.

[0051] See also Figure 4 In some embodiments, the shaft arm 21 has a cavity 23, in which a locking mechanism 40 is provided, and the connecting member 31 is also rotatably disposed in the cavity 23. The locking mechanism 40 is used to cooperate with the connecting member 31 and restrict the rotation of the connecting member 31.

[0052] Understandably, the internal portion of the shaft arm 21 is configured as a cavity 23, and a locking mechanism 40 is installed within it. The connecting piece 31 is also located within the cavity 23, and the connecting piece 31 and the locking mechanism 40 can cooperate with each other. The locking mechanism 40 restricts the rotation of the connecting piece 31, thereby limiting the rotation of the probe 30. This effectively limits the vertical rotation of the probe 30, preventing it from rotating or shaking during measurement. This ensures a stable measurement angle, thereby improving measurement accuracy. Furthermore, since the connecting piece 31 is controlled within the cavity 23 by the locking mechanism 40, the overall size of the rotatable illuminance meter 100 is reduced, making it easier to carry and operate, especially suitable for field measurements and applications requiring high portability.

[0053] See also Figure 5 In some embodiments, ratchet teeth 32 are provided along the outer periphery of the connector 31.

[0054] Understandably, a ratchet 32 ​​is provided on the outer periphery of the connector 31. The ratchet 32 ​​can cooperate with the locking mechanism to restrict the rotation of the connector 31. Specifically, the ratchet 32 ​​allows the connector 31 to rotate only in one direction, that is, clockwise or counterclockwise. When it can only rotate in the clockwise direction, the counterclockwise rotation will be restricted by the locking mechanism 40, so that it cannot reverse, so that the probe 30 can be positioned relatively accurately and the probe will not rotate during detection, thus affecting the measurement accuracy of the probe.

[0055] See also Figure 5 In some embodiments, the locking mechanism 40 includes: a fixing member 41 and a telescopic member 42;

[0056] The fixing member 41 is disposed in the cavity 23. The fixing member 41 is provided with a movable hole 411 through the fixing member 41. The telescopic member 42 is movably disposed in the movable hole 411. The telescopic member 42 is used to cooperate with the ratchet 32 ​​to restrict the rotation of the connecting member 31.

[0057] Understandably, the locking mechanism 40 includes a fixing member 41 and a telescopic member 42. The fixing member 41 is fixedly disposed in the cavity 23 and has a movable hole 411 facing the rotating member. The telescopic member 42 is movably disposed in the movable hole 411. When the telescopic member 42 is subjected to external force, it can extend and retract within the movable hole 411. In this way, the telescopic member 42 can extend to the ratchet 32 ​​and insert itself between the ratchet 32 ​​so that the telescopic member 42 abuts against the ratchet 32. This allows the telescopic member 42 to restrict the rotation of the ratchet 32, thereby achieving the purpose of restricting the rotation of the connecting member 31.

[0058] Understandably, the locking mechanism 40 enables automatic locking and unlocking of the probe 30. When the position of the probe 30 needs to be adjusted, simply continue rotating the probe 30 in a certain direction. This reduces the risk of misoperation, eliminating the need for frequent manual adjustment of the fixing device. Users only need to rotate the probe 30 to a predetermined angle, and the telescopic component 42 will automatically engage with the ratchet 32 ​​for locking, improving ease of use and work efficiency.

[0059] See also Figure 5 In some embodiments, the end of the telescopic member 42 near the connector 31 is provided as an inclined surface.

[0060] Understandably, setting the end of the telescopic component 42 near the connector 31 as an inclined surface allows the telescopic component 42 to smoothly slide into the tooth groove, improving the smoothness of the rotating component during rotation, avoiding sudden stops or jamming, and ensuring that the telescopic component 42 can smoothly lock the ratchet 32 ​​after each rotation to the predetermined position, so that the telescopic component 42 can better cooperate with the ratchet 32.

[0061] See also Figure 1 In some embodiments, the housing 10 is provided with a protrusion 11, the protrusion 11 is provided around the outer periphery of the shaft arm 21, and the connection between the protrusion 11 and the housing 10 is provided with an arc-shaped chamfer.

[0062] Understandably, the protrusion 11 provides a certain supporting force for the extension 211, reducing its sway during rotation and thus improving the stability of the shaft arm 21. The arc-shaped transition on the housing 10 is to eliminate the corners between the housing 10 and the protrusion 11, facilitating the operation of the rotatable illuminance meter 100 by the operator.

[0063] See also Figure 1 In some embodiments, the housing 10 may be provided with components such as adjustment buttons, displays, and batteries. The position of the rotating shaft assembly 20 can be adjusted by controlling the adjustment buttons, thereby achieving the purpose of adjusting the position of the probe 30. When the probe 30 detects the current ambient illuminance, it can display it on the display screen.
