Description

Technical Field

[0001] This application relates to the field of depth detection technology, and in particular to a depth detector and a depth detection device. Background Technology

[0002] Depth detection is a crucial task in many fields, including industrial manufacturing, construction engineering, and scientific research. The accuracy and ease of use of depth detectors directly affect the detection results and work efficiency. Depth detectors are mainly used to measure parameters such as the depth and thickness of objects. Before use, they usually need to be zeroed to ensure the accuracy of the detection data.

[0003] Existing depth detectors often require complex mechanical adjustments or cumbersome electronic calibration procedures to achieve zeroing. For example, some detectors have poorly designed zeroing structures, and the contact between the detection components and the parameter reading unit is not stable enough. During movement, loosening or poor contact may occur, which not only increases the difficulty of zeroing operations but may also lead to deviations in the detection data. Utility Model Content

Furthermore, because the first elastic element continuously provides a stable contact force, ensuring stable contact between the detection component and the parameter reading unit, the stable contact state during zeroing operations with the end of the detection component aligned with the end of the housing allows the parameter reading unit to accurately acquire zeroing data, effectively avoiding zeroing deviations caused by poor contact or looseness. This improves the accuracy of the zeroing operation, providing a more reliable and accurate data foundation for subsequent depth detection.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0041] Some embodiments of this application provide a depth detector, such as Figure 1 and Figure 2 As shown, the depth detector 10 includes a housing 1, a detection component 2, a parameter reading unit 3, and a first elastic element 4.

[0042] The detection component 2 is located inside the housing 1 and is adapted to move along the length of the housing 1 to partially extend out of the housing 1. The portion of the detection component 2 extending out of the housing 1 can extend into the hole to be detected for detecting the depth of the hole.

[0043] The parameter reading unit 3 is located on one side of the detection component 2 and is connected to the housing 1. The parameter reading unit 3 can move along the length of the housing 1. For example, the parameter reading unit 3 is provided with a scale, and after the parameter reading unit 3 moves a certain distance, the distance it has moved can be obtained by reading the readings of the parameter reading unit 3 before and after the movement.

[0044] In this embodiment, the first elastic member 4 is fixed between the detection component 2 and the inner wall of the housing 1 so that the detection component 2 and the parameter reading part 3 abut against each other. For example, the first elastic member 4 can be a spring.

[0045] In this embodiment, the first elastic element 4 is fixed between the detection component 2 and the inner wall of the housing 1, ensuring that the detection component 2 and the parameter reading unit 3 remain in contact. In actual operation, when the end of the detection component 2 is aligned with the end of the housing 1, the data from the parameter reading unit 3 can be directly read to complete the zeroing process, eliminating the need for repeated manual adjustment of the detection component position or complex calibration procedures as required by other existing zeroing operations. Therefore, the depth detector provided in this embodiment simplifies the zeroing process and shortens the time required for zeroing. Furthermore, because the first elastic element 4 continuously provides a stable contact force, ensuring stable contact between the detection component 2 and the parameter reading unit 3, the stable contact state during the zeroing operation when the end of the detection component 2 is aligned with the end of the housing 1 allows the parameter reading unit 3 to accurately acquire zeroing data, effectively avoiding zeroing deviations caused by poor contact or looseness. This improves the accuracy of the zeroing operation and provides a more reliable and accurate data foundation for subsequent depth detection.

[0046] In some examples, the parameter reading unit 3 can be a micrometer head with a scale. By rotating the micrometer head, it can be moved in a direction toward or away from the detection component 2. Then, by reading the data on the scale, the distance that the micrometer head and the detection component 2 move synchronously can be obtained.

[0047] For example, the parameter reading unit 3 can be fixed to the housing 1 by bolts. It is worth noting that fixing the parameter reading unit 3 to the housing 1 means that the housing of the parameter reading unit 3 is fixed to the housing 1, while the part of the parameter reading unit 3 used for measurement can move in a direction toward or away from the detection component 2.

[0048] In other examples, the parameter reading unit 3 includes a body, a displacement sensor, and a display. The displacement sensor is adapted to measure the movement distance of the body, and the display is adapted to show the movement. This enables the depth detector to have a digital display function, avoiding the problems of low reading efficiency and poor accuracy caused by manual reading.

[0049] In some embodiments, such as Figure 2 and Figure 3 As shown, the detection component 2 includes a first connecting portion 21, a second connecting portion 22, and a second elastic member 23 fixed between the first connecting portion 21 and the second connecting portion 22. The first connecting portion 21 is fixedly connected to the first elastic member 22, and the second connecting portion 22 is adapted to move away from the first connecting portion 21 under the action of the second elastic member 23 to partially extend out of the outer casing 1. For example, the second elastic member 23 can be a spring, which allows the first connecting portion 21 and the second connecting portion 22 to move in opposite directions. Since the first connecting portion 21 abuts against the parameter reading portion 3, the second connecting portion 22 can partially extend out of the outer casing 1 under the action of the second elastic member 23.

[0050] In this embodiment, the fixed depth rapid detection function of the depth detector 10 can be realized through the above settings. For example, by adjusting the position of the parameter reading unit 3 so that the end of the detection component 2 is flush with the end of the housing 1, the second elastic member 23 is compressed to its limit position. Then, the reading on the parameter reading unit 3 is read to complete the zeroing step. After completing the zeroing step, the parameter of the parameter reading unit 3 is adjusted to a size consistent with the preset depth, and then the depth detector 10 is used to perform depth detection on the same batch of holes to be detected. When using the depth detector 10, since the second connecting part 22 can move away from the first connecting part 21 and partially extend out of the housing 1 under the action of the second elastic member 23, when the depth of the hole to be detected is less than or equal to the preset depth, the end of the second connecting part 22 can contact the bottom of the hole to be detected earlier. Then, the housing 1 is pressed, and the first connecting part 21 is moved towards the hole to be detected. When the depth of the hole to be detected is equal to the preset depth, the bottom end of the outer casing 1 can just contact the opening of the hole; however, when the depth of the hole to be detected is less than the preset depth, the bottom end of the outer casing 1 cannot contact the opening of the hole, and the two always maintain a certain distance. Furthermore, when the depth of the hole to be detected is greater than the preset depth, the end of the second connecting portion 22 cannot contact the bottom of the hole. In other words, the depth detector 10 in this embodiment can achieve rapid detection of a fixed depth for a batch of holes to be detected.

[0051] Furthermore, when it is necessary to measure the depth of the hole to be tested, the zeroing operation is the same as the aforementioned steps. After completing the zeroing step, the end of the second connecting part 22 is inserted into the hole to be tested and contacts the bottom of the hole. Then, the outer shell 1 is pressed and the first connecting part 21 is moved toward the hole to be tested until the second elastic member 23 is compressed to its limit position. The value on the parameter reading part 3 at this time is read. This value is calculated with the value on the parameter reading part 3 during the zeroing step to obtain the actual depth of the hole to be tested.

[0052] In some embodiments, please continue reading Figure 2 and Figure 3 The first connection part 21 includes: a sleeve 210, a first electrode 211 located inside the sleeve 210 and electrically connected in sequence, a power supply 212 and a second electrode 213, and a conductive connector (e.g., including a wire). The end of the sleeve 210 away from the second connection part 22 abuts against the parameter reading part 3. The two ends of the conductive connector are electrically connected to the first electrode 211 and the second connection part 22, respectively. When the second electrode 213 and the second connection part 22 are in contact, they form a connected detection circuit.

[0053] For example, the first electrode 211 and the second electrode 213 are respectively connected to the positive and negative terminals of the power supply 212. The power supply 212 can be a battery, such as a button cell battery. This can effectively reduce the size of the depth detector 10. The first electrode 211, the power supply 212, the second electrode 213, the conductive connector, and the second connection portion 22 can together form a detection circuit, which is connected when the second connection portion 22 is in contact with the second electrode 213.

[0054] In this embodiment, by measuring whether the detection circuit is connected, it can be determined whether the second connecting part 22 and the second electrode 213 of the first connecting part 21 are in contact. Since the second connecting part 22 and the second electrode 213 form an abutment when in contact, the second connecting part 22 and the first connecting part 21 cannot be further compressed. Therefore, the state of contact between the second connecting part 22 and the second electrode 213 can be considered as a manifestation of the second elastic member 23 being compressed to its limit position. Thus, this embodiment uses the connection of the detection circuit to represent the state of the second elastic member 23 being compressed to its limit position. This allows for quantitative judgment of the state through the on / off state of the detection circuit. Compared to detection methods relying on visual observation or mechanical feedback, this method has higher accuracy and stability, thereby providing reliable assurance for the detection results.

[0055] In some embodiments, such as Figure 1 , Figure 2 and Figure 4As shown, the first connection part 21 also includes a signal light 214 (e.g., a light-emitting diode) disposed on the outside of the sleeve 210. The signal light 214 is electrically connected to the conductive connector and turns on when the detection circuit is connected.

[0056] When the detection circuit is connected, the indicator light 214 immediately turns on and illuminates. Operators do not need to get close to observe the parameter reading unit 3 or determine the positional relationship of the mechanical structure; they can quickly know that the second connection part 22 and the second electrode 213 have made contact simply by looking at the light. This intuitive feedback method reduces the difficulty of operation, especially in low-light environments or in batch rapid testing scenarios, allowing operators to more easily grasp the testing process and thus improving operational convenience.

[0057] Furthermore, during the zeroing step, by adjusting the position of the parameter reading unit 3 so that the end of the detection component 2 is flush with the end of the housing 1, if the second elastic member 23 is not compressed to its limit position or the second connecting part 22 is not in contact with the second electrode 213, the indicator light 214 will not illuminate. In this case, the parameter reading unit 3 is moved toward the detection component 2 until the indicator light 214 illuminates, and the reading on the parameter reading unit 3 is read, thus completing the zeroing step. Therefore, the indicator light 214 effectively ensures the accuracy of the zeroing data measured during the zeroing step.

[0058] Furthermore, when implementing a fixed-depth rapid detection function, once indicator light 214 illuminates during the detection of a hole, observing whether the bottom of the outer casing 1 has contacted the opening of the hole allows for a quick determination of whether the hole's depth meets the preset requirements, and then proceeds to the next hole for detection. This effectively shortens the detection cycle for a single hole. Simultaneously, this status feedback mechanism, combined with the zeroing step and batch detection design, further enhances overall detection efficiency, making it particularly suitable for quality inspection in large-scale production.

[0059] In some examples, the sleeve 210 is fitted inside the housing 1, and the side wall of the housing 1 has a clearance groove 101, in which the indicator light 214 is located. The length direction of the clearance groove 101 is consistent with the length direction of the housing 1.

[0060] The clearance slot 101 allows the indicator light 214 to be embedded in the side wall of the housing 1, placing it at eye level or in a more easily observable position. This ensures that during detection, the operator can quickly and clearly observe the status of the indicator light 214 without adjusting the angle or deliberately searching for it. Furthermore, the clearance slot 101 prevents the indicator light 214 from occupying additional external space. This results in a relatively compact structure for the depth detector 10, reducing the overall size of the device without compromising functionality. This makes it suitable for handheld operation, as well as convenient to carry and install.

[0061] In some embodiments, such as Figure 2 and Figure 3 As shown, the sleeve 210 includes a first sleeve portion 2101 and a second sleeve portion 2102 that are detachably connected. The first sleeve portion 2101 abuts against the parameter reading unit 3, and a mounting cavity is provided inside the first sleeve portion 2101, where the power supply 212 is disposed. Because the first sleeve portion 2101 and the second sleeve portion 2102 are detachably connected, the mounting cavity is easily exposed, facilitating the installation of the power supply 212. Furthermore, the second sleeve portion 2102 is connected to the first elastic member 4, and the second electrode 213 is fixed to the second sleeve portion 2102.

[0062] In some examples, the first sleeve portion 2101 is made of an insulating material. The second sleeve portion 2102 may be made of a conductive material, and the second electrode 213 is spaced apart from the second sleeve portion 2102 by an insulating portion to avoid electrical contact between the second electrode 213 and the second sleeve portion 2102. Furthermore, the portion of the second connecting portion 22 that contacts the second electrode 213 (e.g., the detection needle mounting portion 222) is also made of a conductive material. This allows the detection circuit to be connected when the second electrode 213 contacts (or abuts) the second connecting portion 22.

[0063] As an example, the signal lamp 214 can be fixed to and electrically connected to the second sleeve 2102, thereby enabling the signal lamp 214 to be connected to the detection circuit.

[0064] In some examples, an insulating member 24 is fixed to one side of the second electrode 213, the second sleeve portion 2102 has a sliding chamber, the second connecting portion 22 is partially located in the sliding chamber, and is connected to the insulating member 24 through the second elastic member 23.

[0065] During depth detection by the depth detector 10, the detection component 2 moves frequently. If the second electrode 213 accidentally becomes conductive with other conductive components, it will affect the normal operation of the detection circuit and the depth detection results. By providing the insulating component 24, the direct conductivity between the second electrode 213 and the second connection portion 22 can be effectively avoided when the second elastic component 23 is made of metal spring, thus ensuring the normal operation of the detection circuit. In addition, the sliding chamber of the second sleeve portion 2102 provides a precise movement guide space for the second connection portion 22. The second connection portion 22 is partially placed in the sliding chamber and moves along the length direction of the sliding chamber under the action of the second elastic component 23, which can effectively prevent the second connection portion 22 from shifting or shaking during movement.

[0066] In some embodiments, such as Figure 2 , Figure 3 and Figure 5As shown, the second connecting part 22 includes a detachably connected detection needle 221 and a detection needle mounting part 222. The detection needle mounting part 222 is connected to the first connecting part 21 through a second elastic member 23, and moves away from the first connecting part 21 under the action of the second elastic member 23. The detection needle 221 extends out of the outer shell 1 under the drive of the detection needle mounting part 222.

[0067] Because the detection needle 221 and the detection needle mounting part 222 are detachably connected, it is convenient to replace the detection needle 221 when its diameter does not match the inner diameter of the hole to be tested, or when its length does not match the depth of the hole to be tested. Furthermore, as the component that directly contacts the hole to be tested, the detection needle 221 is prone to wear and damage during long-term use. By detachably connecting the detection needle 221 and the detection needle mounting part 222, when the detection needle malfunctions, the operator does not need to replace the entire second connection part 22 or the detection assembly 2; only the detection needle 221 needs to be removed and a new detection needle installed to complete the repair. This effectively reduces maintenance costs and minimizes resource waste caused by replacing the entire component.

[0068] It is worth noting that the probe can be replaced with a go gauge, which can measure the hole diameter while measuring the hole depth. It is only used as a depth and hole diameter plug gauge and does not provide specific measurement figures.

[0069] In some examples, the second connecting portion 22 includes a threaded sleeve 223, which is threadedly connected to the probe mounting portion 222. When the threaded sleeve 223 is installed on the probe mounting portion 222, it can tighten the probe mounting portion 222 to fix the probe 221.

[0070] In some examples, the second electrode 213 and the detection needle mounting portion 222 form a connected detection circuit when they are in contact. For example, the detection needle mounting portion 222 may be made of a conductive material.

[0071] In some embodiments, such as Figure 1 and Figure 6 As shown, the outer casing 1 includes a first casing part 11 and a second casing part 12 that are detachably connected, and the parameter reading part 3 is fixed to the first casing part 11.

[0072] By providing a detachable connection between the first housing part 11 and the second housing part 12, it is convenient to install the detection component 2, and it is also possible to replace the second housing part 12 with different sizes. For example, when the depth feature space of the hole to be detected is large, a larger size second housing part 12 can be used.

[0073] In some examples, the second housing portion 12 has a limiting end 121 through which the detection needle 221 can extend out of the housing 1. The inner diameter of the limiting end 121 can be adapted to the outer diameter of the detection needle 221 to ensure the stability of the movement of the detection needle 221.

[0074] In some examples, the second housing portion 12 has a step 122, on which the first elastic member 4 is fixed. The second housing portion 12 can be threadedly connected to the first housing portion 11, with one end of the second housing portion 12 extending into the first housing portion 11 and serving as the step 122 for fixing to the first elastic member 4.

[0075] In some embodiments, such as Figure 1 As shown, the depth detector 10 also includes a locking structure for stopping the parameter reading unit 3. For example, in the process of implementing the fixed depth rapid detection function, after adjusting the parameters of the parameter reading unit 3 to a size consistent with the preset depth, the locking structure is used to lock the parameter reading unit 3 to prevent it from moving and affecting the subsequent detection results.

[0076] Furthermore, when it is necessary to read the value on the parameter reading unit 3, the position of the parameter reading unit 3 can be locked by the locking structure to prevent the position of the parameter reading unit 3 from changing due to accidental touch and affecting the final measurement result.

[0077] In some examples, the housing 1 has an opening 102, and the locking structure is inserted into the opening 102 and abuts against the parameter reading part 3 to stop the parameter reading part 3.

[0078] Some embodiments of this application also provide a depth detection device, which includes the depth detector 10 described in any of the above embodiments.

[0079] Since it includes a depth detector 10, the depth detection device has the technical effects of the aforementioned depth detector, which will not be described in detail here.

[0080] Exemplarily, the depth detector 10 in the depth detection device includes a housing 1, a detection component 2, a parameter reading unit 3, and a first elastic member 4. The detection component 2 is located inside the housing 1 and is adapted to move along the length of the housing 1 to partially extend out of the housing 1. The parameter reading unit 3 is located on one side of the detection component 2 and connected to the housing 1. The first elastic member 4 is fixed between the detection component 2 and the inner wall of the housing 1 so that the detection component 2 and the parameter reading unit 3 abut against each other.

[0081] The first elastic element 4 is fixed between the detection component 2 and the inner wall of the housing 1, ensuring that the detection component 2 and the parameter reading unit 3 remain in contact at all times. In actual operation, when the end of the detection component 2 is aligned with the end of the housing 1, the data from the parameter reading unit 3 can be directly read to complete the zeroing process, eliminating the need for repeated manual adjustment of the detection component position or complex calibration procedures as required by other existing zeroing operations. Therefore, the depth detector provided in this embodiment simplifies the zeroing process and shortens the time required for zeroing. Furthermore, because the first elastic element 4 continuously provides a stable contact force, ensuring stable contact between the detection component 2 and the parameter reading unit 3, the stable contact state during the zeroing operation when the end of the detection component 2 is aligned with the end of the housing 1 allows the parameter reading unit 3 to accurately acquire zeroing data, effectively avoiding zeroing deviations caused by poor contact or loosening. This improves the accuracy of the zeroing operation and provides a more reliable and accurate data foundation for subsequent depth detection.

[0082] Furthermore, the aforementioned depth detectors and detection devices offer advantages such as small size, light weight, single-handed operation, high portability, and wide applicability. They are particularly advantageous when the product depth is shallow or the product space is narrow.
