Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe wall thickness detection technology, and in particular to a pipe wall thickness detection device. Background Technology
[0002] In industrial production and equipment maintenance, accurate measurement of pipe wall thickness is crucial, as it relates to the safety, reliability, and service life of the pipeline system. Ultrasonic thickness gauges, as a commonly used and efficient testing device, are widely applied in various pipe wall thickness measurement scenarios due to their ease of operation and high accuracy. Some probes are connected to the lead wire via a direct plug-in connection. While this method is convenient to some extent, the testing environment is often complex and variable. Operators may accidentally pull on the lead wire for various reasons. Because direct plug-in connections are relatively fragile, the probe and lead wire can easily separate, leading to interruptions in the testing process. This not only wastes testing time and affects work efficiency but may also result in the loss of critical test data due to the interruption, adversely affecting the accurate assessment of the pipeline condition.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Example 1
[0028] Reference Figures 1-5This is the first embodiment of the present utility model. This embodiment provides a pipe wall thickness detection device. The pipe wall thickness detection device includes a main component 100, including a probe 101, a fixing block 102, a wire end 103, and a connector 104. The fixing block 102 is fixed on the probe 101. A wire interface 102-1 is opened on the fixing block 102. The wire end 103 is disposed on one side of the probe 101. The connector 104 is fixed on the wire end 103.
[0029] An ultrasonic thickness gauge is an instrument used to measure the thickness of an object based on the propagation characteristics of ultrasonic waves. The probe 101 is used to transmit and receive ultrasonic signals. One end of the wire 103 is fixed with a wire 105. The probe 101 is connected to the ultrasonic thickness gauge through the wire 105. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.
[0030] The locking component 200 is located on the probe 101 and includes a trigger 201. The trigger 201 includes a contact block 201a, a button 201b, and an extension plate 201c. The contact block 201a is fixed on the probe 101 and has a sliding groove 201a-1. The button 201b slides in the sliding groove 201a-1, and the extension plate 201c is fixed to one end of the button 201b.
[0031] The trigger 201 is used to lock the connection between the wire interface 102-1 and the connector 104 when the ultrasonic thickness gauge is needed to detect the thickness. This effectively prevents the detection from being interrupted due to the wire 105 being accidentally pulled by external force during the detection process, which would cause the probe 101 to separate from the wire end 103.
[0032] In the initial state, part of button 201b is not located in the slide 201a-1, and its end face protrudes from the end face of contact block 201a. At the start of the test, the tester needs to ensure that his hand is in the position of contact block 201a and press button 201b, thereby driving extension plate 201c to move so as to trigger subsequent locking.
[0033] The locking assembly 200 also includes a locking element 202, which is disposed in the fixing block 102 and includes a force-bearing plate 202a and a locking block 202b. The fixing block 102 has a first moving groove 102-2, the force-bearing plate 202a slides in the first moving groove 102-2, and the locking block 202b is fixed to one side of the force-bearing plate 202a. The connector 104 has a locking groove 104-1, and the locking block 202b can engage with the locking groove 104-1.
[0034] The locking element 202 locks the connection between the wire interface 102-1 and the connector 104, ensuring the stability and reliability of the connection between the probe 101 and the wire end 103.
[0035] The fixed block 102 has a groove corresponding to the locking block 202b. The two are of the same size. A part of the locking block 202b is always located in the groove. At the same time, it can guide the movement of the force plate 202a, ensuring that the force plate 202a can move smoothly in the first moving groove 102-2.
[0036] The movement of the extension plate 201c will cause the force plate 202a to move, and the locking block 202b will move along with the force plate 202a. After the wire interface 102-1 is connected to the connector 104, the locking block 202b and the locking groove 104-1 will be in a coaxial position. At this time, under the push of the force plate 202a, the locking block 202b and the locking groove 104-1 will engage, so that the position of the wire interface 102-1 in the fixed block 102 will not change, thereby avoiding the accidental pulling of the wire 105 during the test, which would cause the test to be interrupted.
[0037] Example 2
[0038] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0039] Specifically, a first spring 201d is fixed to one side of the button 201b, and the other end of the first spring 201d is fixed to the inner wall of the slide groove 201a-1.
[0040] The first spring 201d applies a continuous pushing force to the button 201b, ensuring that, without any other external force, the end face of the button 201b away from the first spring 201d will protrude from the end face of the contact block 201a. This allows the testing personnel to squeeze the button 201b when they pick up the probe 101 from the position of the contact block 201a, thereby compressing the first spring 201d and changing the position of the extension plate 201c.
[0041] When the operator's finger leaves the button 201b, the button 201b will return to its original position under the push of the first spring 201d. The elastic force of the first spring 201d is small, making it easy for the operator to press the button 201b.
[0042] Specifically, the trigger 201 also includes a connecting rod 201e and a push plate 201f. The connecting rod 201e is fixed on the extension plate 201c, and the push plate 201f is fixed on one side of the push plate 201f.
[0043] The other end of the push plate 201f is fixed to the force plate 202a. The extension plate 201c is connected to the force plate 202a by the connecting rod 201e. When the button 201b moves the extension plate 201c, the force plate 202a can move synchronously in the first moving groove 102-2 towards the joint 104.
[0044] Once the wire interface 102-1 is connected to the connector 104, press button 201b to move extension plate 201c. At this time, extension plate 201c will move connecting rod 201e and push plate 201f will move synchronously, causing force plate 202a to move closer to connector 104. Force plate 202a will move locking block 202b, and locking block 202b will engage with locking groove 104-1, so that the position of wire interface 102-1 in fixed block 102 will not change, thereby avoiding accidental pulling of wire 105 during the test, which would cause the test to be interrupted.
[0045] Specifically, the connecting rod 201e forms a certain angle with the extension plate 201c and the push plate 201f.
[0046] In the initial state, the end face of the push plate 201f near the connecting rod 201e is still a certain distance from the fixed block 102. This ensures that when the extension plate 201c drives the connecting rod 201e and the push plate 201f, the connection between the push plate 201f and the connecting rod 201e will not be in contact with the fixed block 102, thus affecting the movement of the extension plate 201c.
[0047] Specifically, the contact block 201a has a second moving groove 201a-2, and the extension plate 201c slides within the second moving groove 201a-2.
[0048] When button 201b is pressed to compress the first spring 201d, extension plate 201c will move along the second moving groove 201a-2 toward the joint 104.
[0049] Specifically, a buffer block 202c is fixed on one side of the locking block 202b, and the buffer block 202c has a certain deformation capability.
[0050] One side of the buffer block 202c is fixed to the force plate 202a. When the wire 105 is pulled, the end face of the locking groove 104-1 near the probe 101 will first contact and squeeze the buffer block 202c, causing the buffer block 202c to deform, thereby buffering the tension on the wire 105 and protecting the connector 104.
[0051] Example 3
[0052] Reference Figures 1-5 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0053] Specifically, the fixing block 102 has a rectangular groove 102-3, and a second spring 201g is installed in the rectangular groove 102-3. The two ends of the second spring 201g are fixed to the inner wall of the rectangular groove 102-3 and one end of the force plate 202a.
[0054] The second spring 201g applies a continuous pulling force to the force plate 202a to assist in the reset of the force plate 202a. When the force plate 202a moves and the locking block 202b engages with the locking groove 104-1, the second spring 201g is in an extended state. If the button 201b is stopped being pressed, the first spring 201d will return to its original state, driving the button 201b, extension plate 201c, connecting rod 201e and push plate 201f to reset. Since the force plate 202a is relatively long, the second spring 201g is set to assist in the reset.
[0055] Specifically, there are two sets of trigger elements 201 and locking elements 202, which correspond one-to-one and are symmetrically distributed on both sides of the probe 101.
[0056] When the operator holds the probe 101, the thumb and forefinger pinch the probe 101 from two directions. By setting two sets of triggering elements 201 and locking elements 202, it is ensured that when the operator holds the probe, the locking of the wire interface 102-1 and the connector 104 can be triggered from both directions, ensuring the reliability of the connection between the two.
[0057] Specifically, the probe 101 is provided with a handheld area 101-1, and the contact block 201a is provided on the handheld area 101-1.
[0058] When preparing to start the test, the operator needs to ensure that the finger is in the hand area 101-1 and press the finger against the button 201b to trigger the lock.
[0059] Specifically, there are two connectors 104 and wire interface 102-1, and connector 104 can engage with wire interface 102-1.
[0060] The connection between connector 104 and wire interface 102-1 is existing technology, and will not be described in detail here. Moreover, those skilled in the art can clearly understand the working principle. Even when connector 104 and wire interface 102-1 are not locked, connector 104 and wire interface 102-1 will not easily separate without pulling the wire 105. When it is necessary to separate the two, a certain pushing force is applied to the wire end 103 to separate connector 104 and wire interface 102-1.
[0061] Each connector 104 has two locking slots 104-1, so that when connecting the connector 104 to the wire interface 102-1, the direction of the connector 104 does not need to be considered. After pressing the button 201b, the locking block 202b can be engaged with the locking slot 104-1, thereby improving the stability and reliability of the connection.
[0062] When in use, first connect the probe 101 to the wire 105. The operator's fingers are in the handheld area 101-1, ensuring that they do not contact the button 201b. Move the wire end 103 so that the connector 104 and the wire interface 102-1 are in a coaxial position. Then push the wire end 103 to connect the connector 104 and the wire interface 102-1. At this time, the locking block 202b and the locking groove 104-1 will be in a coaxial position.
[0063] When preparing to start the test, the operator needs to ensure that their fingers are in the handheld area 101-1 and that their fingers are pressing the button 201b. Pressing the button 201b compresses the first spring 201d, which in turn moves the extension plate 201c. At this time, the extension plate 201c moves the connecting rod 201e and the push plate 201f moves synchronously, causing the force plate 202a to move closer to the connector 104. The force plate 202a moves the locking block 202b, which engages with the locking groove 104-1. This prevents the wire interface 102-1 from changing its position within the fixed block 102, thus avoiding accidental pulling of the wire 105 during the test and preventing the test from being interrupted.
[0064] After the test is completed, the operator removes his finger from button 201b to ensure that button 201b is no longer squeezed. Then, the position of button 201b will be reset by the first spring 201d, which will drive the extension plate 201c, connecting rod 201e, push plate 201f and force plate 202a to reset, thereby separating the locking block 202b from the locking groove 104-1. At this time, a certain pushing force is applied to the wire end 103, which will separate the connector 104 from the wire interface 102-1.
[0065] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
