Description

Technical Field

[0001] This utility model belongs to the field of detection equipment, and in particular relates to a combined microseismic life detector. Background Technology

[0002] Microseismic life detectors are a common type of security screening equipment. When in use, staff place the detector's sensor probe against the exterior of the object being tested. If a living organism is present inside, the vibrations generated by its heartbeat and respiration will be detected by the sensor probe. The probe then converts these vibrations into electrical signals and sends them to the controller, allowing staff to determine whether a living organism is hiding inside the object based on the controller's display.

[0003] However, since staff cannot remain absolutely still when using the induction probe, nor can they ensure that the induction probe maintains a constant contact with the object being measured throughout the detection process, the detection results of the micro-vibration life detector are easily interfered with during actual use, resulting in errors in the detection results. Utility Model Content

[0004] In view of this, the present invention aims to propose a combined microseismic life detector to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A combined microseismic life detector includes a sensing probe and a controller, with the sensing probe electrically connected to the controller via a connecting wire. The combined microseismic life detector further includes an adsorption plate, a locking sleeve, and a connecting sleeve. The bottom surface of the adsorption plate is provided with an adsorption assembly, and a detection hole is provided at the center of the adsorption plate. A mounting plate is also provided above the adsorption plate, connected to it via a connecting rod. The mounting plate has a receiving hole aligned with the detection hole, and a compression spring is provided on the connecting rod. The locking sleeve is vertically and flexibly positioned inside the receiving hole. A limiting ring is provided at one end, located between the adsorption plate and the mounting plate. The limiting ring has a connecting hole for accommodating the connecting rod, and one end of the compression spring is connected to the limiting ring, while the other end is connected to the mounting plate. The connecting sleeve is adjustablely fitted around the outside of the sensing probe. A spring plunger is provided on the outer wall of the connecting sleeve, and a locking groove for accommodating the spring plunger is provided on the inner wall of the locking sleeve. When the spring plunger enters the locking groove, the bottom end of the sensing probe is flush with the bottom surface of the adsorption plate, and the compression spring is compressed by the mounting plate and the limiting ring.

[0007] Furthermore, the combined microseismic life detector also includes an isolation sleeve, which is detachably fitted onto the outside of the mounting plate, and has a splicing ring groove on the top surface of the adsorption plate for accommodating the bottom end of the isolation sleeve.

[0008] Furthermore, the top of the locking sleeve is provided with a guide inner conical surface.

[0009] Furthermore, the top of the locking sleeve is provided with an operating ring, and the bottom of the operating ring is provided with an operating outer conical surface.

[0010] Furthermore, the adsorption assembly includes multiple arc-shaped adsorption strips, which are arranged in a ring around the periphery of the detection hole, and the center of any arc-shaped adsorption strip faces the detection hole.

[0011] Furthermore, the arc-shaped adsorption strip is an arc-shaped magnetic strip or an arc-shaped adhesive strip.

[0012] Furthermore, the inner wall of the locking sleeve is provided with a guide groove, the length direction of the guide groove is parallel to the axial direction of the locking sleeve, and the locking groove is located inside the guide groove.

[0015] Compared with existing technologies, the combined microseismic life detector described in this utility model has the following advantages:

[0016] This utility model discloses a combined microseismic life detector. An adsorption assembly is provided on the adsorption plate. During use, the operator can fix the adsorption plate to the object to be measured using the adsorption assembly. The sensing probe is then installed onto the adsorption plate via a connecting sleeve and a locking sleeve.

Furthermore, the device has a compression spring on the connecting rod, and spring plungers and locking grooves on the connecting sleeve and locking sleeve, respectively. During use, the operator can fix the relative position of the connecting sleeve and locking sleeve through the cooperation of the spring plunger and the locking groove.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] A combined microseismic life detector, the structure of which can be made of Figures 1-5 The following is an illustration. Similar to common microseismic life detectors, the combined microseismic life detector in this embodiment includes a sensing probe 1 and a controller (not shown in the figure), and the sensing probe 1 is electrically connected to the controller via a connecting cable 11. In use, the sensing probe 1 can detect minute vibrations in the object under test and convert the vibrations into electrical signals. These electrical signals are then transmitted to the controller via the connecting cable 11, allowing personnel to determine whether there is a living organism hiding inside the object under test based on the display results on the controller.

[0030] Because existing microseismic life detectors cannot maintain absolute stillness of their sensing probes during use, nor can they ensure a constant contact with the object being measured throughout the detection process, the detection results are prone to errors. To solve this problem, the combined microseismic life detector provided in this embodiment further includes: an adsorption plate 2, a locking sleeve 3, and a connecting sleeve 4. The adsorption plate 2 is used to fix the relative position between the device and the object being measured, while the locking sleeve 3 and the connecting sleeve 4 are used to fix the relative position between the sensing probe 1 and the adsorption plate 2, and to ensure that the sensing probe 1 maintains a good contact with the object being measured during use.

[0031] Specifically, the bottom surface of the adsorption plate 2 is provided with an adsorption assembly, and a detection hole 21 is provided in the center of the adsorption plate 2 to facilitate contact between the sensing probe 1 and the object to be measured. A mounting plate 5 is also provided above the adsorption plate 2. The mounting plate 5 is connected to the adsorption plate 2 through a connecting rod 6. The mounting plate 5 is provided with a receiving hole 51 that is aligned with the detection hole 21, and a compression spring 61 is provided on the connecting rod 6.

[0032] Optionally, to improve the adsorption effect between the adsorption plate 2 and the object to be tested, such as... Figure 3 As shown, the adsorption assembly may include multiple arc-shaped adsorption strips 22, which should be arranged in a ring around the periphery of the detection hole 21, and the center of any arc-shaped adsorption strip 22 should face the detection hole 21.

[0033] For example, the arc-shaped adsorption strip 22 in this embodiment can be an arc-shaped magnetic strip or an arc-shaped adhesive strip. When the object to be tested is a ferromagnetic metal material, an arc-shaped magnetic strip can be used as the arc-shaped adsorption strip 22. When the object to be tested is other materials, an arc-shaped adhesive strip can be used, so that the device can adapt to different types of objects to be tested and achieve a good contact and fixation effect between the device and the object to be tested.

[0034] like Figure 4 and Figure 5As shown, the locking sleeve 3 is vertically adjustable inside the receiving hole 51. A limiting ring 31 is provided at the bottom of the locking sleeve 3, and a connecting hole 311 for accommodating the connecting rod 6 is provided on the limiting ring 31. The connecting sleeve 4 is adjusted in position and fitted onto the outside of the sensing probe 1 via a threaded connection. A spring plunger 41 is provided on the outer wall of the connecting sleeve 4, and a locking groove 32 for accommodating the spring plunger 41 is provided on the inner wall of the locking sleeve 3. After assembly, the limiting ring 31 should be located between the adsorption plate 2 and the mounting plate 5, with one end of the compression spring 61 connected to the limiting ring 31 and the other end connected to the mounting plate 5. During use, the operator can insert the sensing probe 1 with the connecting sleeve 4 into the locking sleeve 3, so that the bottom end of the sensing probe 1 (i.e., the end of the sensing probe 1 that detects vibration) contacts the object to be measured along the detection hole 21, and the bottom end of the sensing probe 1 is flush with the bottom surface of the adsorption plate 2. Then, pull up the locking sleeve 3, causing the spring plunger 41 to enter the locking groove 32. After the spring plunger 41 enters the locking groove 32, the relative position between the locking sleeve 3 and the connecting sleeve 4 will be fixed. The bottom end of the sensing probe 1 will still be in contact with the object to be measured. The compression spring 61 will be squeezed by the mounting plate 5 and the limiting ring 31, thus entering a compressed state. The compressed state will cause the compression spring 61 to generate an elastic force. This elastic force will be transmitted to the sensing probe 1 through the locking sleeve 3, so that the sensing probe 1 and the object to be measured can obtain a constant and reliable pressing effect during use.

[0035] It should be noted that, in order to avoid abnormal shaking of the sensing probe 1 during use, the outer diameter of the connecting sleeve 4 in this embodiment should be equal to the inner diameter of the locking sleeve 3, the outer diameter of the locking sleeve 3 should be equal to the inner diameter of the receiving hole 51, and a silicone coating should be provided on the outer wall of the connecting sleeve 4 and the outer wall of the locking sleeve 3.

[0036] Optionally, to facilitate the insertion of the connecting sleeve 4 with the spring plunger 41 into the locking sleeve 3, the top of the locking sleeve 3 is provided with a guideable inner conical surface 33. When the spring plunger 41 contacts the guideable inner conical surface 33, the guideable inner conical surface 33 will squeeze the spring plunger 41 so that the connecting sleeve 4 can smoothly enter the locking sleeve 3.

[0037] In addition, to ensure that the spring plunger 41 can smoothly enter the locking groove 32, the inner wall of the locking sleeve 3 may also be provided with a guide groove 35 whose length direction is parallel to the axis direction of the locking sleeve 3, and the locking groove 32 should be located inside the guide groove 35, so as to guide the spring plunger 41 with the help of the guide groove 35.

[0038] As an optional implementation of this embodiment, in order to facilitate the operator to pull up the locking sleeve 3, an operating ring 34 may be provided at the top of the locking sleeve 3, and an operating outer cone surface 341 is provided at the bottom of the operating ring 34, so that the operating ring 34 can apply force to the locking sleeve 3 during use and drive the locking sleeve 3 to move.

[0039] In practical applications, the required contact force between the sensing probe 1 and the object under test varies depending on the application scenario. To meet different contact force requirements, multiple locking grooves 32 can be provided, and these multiple locking grooves 32 should be arranged along the axial direction of the locking sleeve 3. Before use, the operator can adjust the position of the connecting sleeve 4 on the sensing probe 1 according to the actual contact force requirements. Then, the sensing probe 1 with the connecting sleeve 4 is inserted into the locking sleeve 3. Next, the locking sleeve 3 is pulled up, and the locking groove 32 that accommodates the spring plunger 41 is selected according to the actual contact force requirements. When the position of the connecting sleeve 4 on the sensing probe 1 and the locking groove 32 that accommodates the spring plunger 41 are different, the compression amplitude of the compression spring 61 will change. This allows the sensing probe 1 to obtain different contact forces with the object under test, ensuring good results in subsequent detection work.

[0040] As an optional implementation of this embodiment, to prevent abnormal vibration of the sensing probe 1 caused by external environmental influences, the combined micro-vibration life detector may also include an isolation sleeve 7. During assembly, the isolation sleeve 7 is detachably fitted onto the outside of the mounting plate 5 via a threaded connection, and a splicing ring groove 23 for accommodating the bottom end of the isolation sleeve 7 is provided on the top surface of the adsorption plate 2. By setting the isolation sleeve 7, the area between the mounting plate 5 and the adsorption plate 2 can be shielded, preventing the sensing probe 1 from being affected by the external environment.

[0041] The effects of the above solution are explained below:

[0042] This embodiment provides a combined microseismic life detector that can be fixed to the object under test via an adsorption plate, avoiding prolonged hand-holding of the sensor probe during detection, reducing the operational difficulty for operators, and preventing the detection results from being affected by abnormal movement of the operator. Furthermore, this device, through the cooperation of a locking sleeve, a compression spring, and a connecting sleeve, ensures that the sensor probe reliably rests against the object under test, thereby improving the ease of use of the microseismic life detector and further enhancing the accuracy of the detection results.

[0043] It should be noted that the sensing probe in this embodiment is a common component of micro-vibration life detectors in the prior art. Its internal structure, usage method and working principle are already well known to the public and are not an improvement point of this application, so they will not be described in detail in this application.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
