Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic ultrasonic transmitting probes, in particular to an electromagnetic ultrasonic transmitting probe for a thickness gauge. Background Art

[0002] Due to the harsh working environment and long-term online operation, pipelines are prone to defects such as cracks and corrosion, which pose a safety hazard. By detecting defects and taking corresponding measures, economic benefits can be improved and accidents can be avoided. Ultrasonic testing technology is currently the most frequently used and widely used testing technology in the field of non-destructive testing. In the existing technology, there are many instruments for testing, including thickness gauges, which are instruments used to measure the thickness of materials and objects. However, thickness gauges still have shortcomings during use, such as the protection of the transmitting probe.

[0003] In the prior art, there is an ultrasonic thickness gauge with probe protection (Announcement No.: CN221280206U). It protects the probe body by providing a protective groove on the thickness gauge body to prevent the probe body from falling out during carrying, thereby achieving the protection effect of the probe body.

[0004] However, in actual use, when the probe body is taken out of the protective groove to measure external objects, there are no protective measures on the probe body, which makes the probe body easy to collide with external objects during measurement, thereby being damaged. In addition, the probe body needs to be held by the user for a long time during long-term use, which reduces the user's convenience in operating the thickness gauge and reduces the user's comfort in using the thickness measurement. Utility Model Content

[0005] Aiming at the problems existing in the background technology, an electromagnetic ultrasonic transmitting probe of a thickness gauge is proposed.

[0006] The utility model provides an electromagnetic ultrasonic transmitting probe for a thickness gauge, comprising a probe body, an outer shell provided on the probe body, the outer shell consisting of a threaded sleeve, a first flexible collar, and an intermediate collar. The threaded sleeve is threadably mounted on the probe body, the first flexible collar is mounted below the threaded sleeve, and the intermediate collar is mounted below the first flexible collar. The probe body is also provided with a lower shell, the lower shell consisting of a connecting ring, a second flexible collar, and a blocking piece. The connecting ring is sleeved on the probe body, the second flexible collar is mounted on the connecting ring, and the blocking piece is mounted on the second flexible collar. The outer shell and the lower shell are connected by a connecting assembly, and the outer shell and the lower shell are used to wrap and protect the probe body.

[0007] Preferably, the connecting assembly is composed of an L-shaped connecting head, and a connecting slot is provided on the middle collar. The connecting ring can be connected to the middle collar by passing the L-shaped connecting head through the connecting slot and rotating the connecting ring.

[0008] Preferably, a rubber extrusion pad is provided on the L-shaped connector to increase the friction between the L-shaped connector and the surface of the intermediate ring.

[0009] Preferably, the flexible collar 1 and the flexible collar 2 are both made of rubber.

[0010] Preferably, the probe body is provided with an outer shell, the top of the outer shell is set to an inverted T shape, and the outer shell is provided with an external thread, which is used to cooperate with the threaded sleeve to complete the installation of the outer shell.

[0011] Preferably, a double-sided adhesive ring is adhered to the bottom of the flexible sleeve ring 2, and the sealing piece is connected to the double-sided adhesive ring by gluing.

[0012] Preferably, the blocking piece is made of tin foil, and a protruding piece is provided on the blocking piece for tearing the blocking piece off from the double-sided adhesive ring.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] The outer shell and the lower shell provide a better protection for the probe body, which protects the probe body during storage and prevents the probe body from colliding with external objects during measurement, thus improving the protection effect of the probe body.

[0015] By providing a double-sided adhesive ring at the bottom of the lower housing, a relatively stable state can be formed between the probe body and the object being measured during use, eliminating the need for the operator to hold the probe, thereby improving the convenience and comfort of using the thickness gauge.

[0016] By separating the lower shell, the outer shell and the probe body, the probe body can be quickly replaced during the detection process without causing the detection position to deviate, thereby ensuring the detection effect of the thickness gauge. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-Figure 5 As shown, the electromagnetic ultrasonic transmitting probe of a thickness gauge proposed by the present invention includes: a probe body 1, an outer shell 2 and a lower shell 3.

[0024] like Figure 1-Figure 5 As shown, the outer shell 2 is composed of a threaded sleeve 4, a flexible ring 15 and an intermediate ring 6. The threaded sleeve 4 is installed on the probe body 1 by a threaded connection. The flexible ring 15 is installed below the threaded sleeve 4. The intermediate ring 6 is installed below the flexible ring 15. The lower shell 3 is composed of a connecting ring 8, a flexible ring 2 10 and a sealing piece 12. The connecting ring 8 is sleeved on the probe body 1, the flexible ring 2 10 is installed on the connecting ring 8, and the sealing piece 12 is arranged on the flexible ring 2 10. The outer shell 2 and the lower shell 3 are connected by a connecting assembly. The outer shell 2 and the lower shell 3 are used to wrap and protect the probe body 1.

[0025] like Figure 1 、 Figure 3 and Figure 5 The shown connecting assembly consists of an L-shaped connecting head 9, and a connecting groove 7 is provided on the intermediate ring 6. The connecting ring 8 can be connected to the intermediate ring 6 by passing the L-shaped connecting head 9 through the connecting groove 7 and rotating the connecting ring 8. A rubber extrusion pad is provided on the L-shaped connecting head 9 to increase the friction between the L-shaped connecting head 9 and the surface of the intermediate ring 6. By increasing the friction, the connection between the L-shaped connecting head 9 and the intermediate ring 6 is made more stable.

[0026] like Figures 1-4 The flexible sleeve 1 5 and the flexible sleeve 2 10 shown are both made of rubber material. By setting the flexible sleeve 1 5 to be made of rubber material, the operator can press the probe body 1 to contact the object, so that different types of probes can be used. For this purpose, it is necessary to open an air vent on the flexible sleeve 1 5 to ensure the pressure inside and outside the flexible sleeve 1 5. By setting the flexible sleeve 2 10 to be made of rubber material, it can be used for buffering when it contacts the surface of the object, avoiding collision between the probe body 1 and the object, and improving the protection effect of the probe body 1.

[0027] like Figure 2-Figure 4The probe body 1 shown is provided with an outer shell, the top of the outer shell is set to an inverted T shape, and the outer shell is provided with an external thread. The external thread is used to cooperate with the threaded sleeve 4 to complete the installation of the outer shell 2. Through the setting of the external thread and the threaded sleeve 4, the probe body 1 and the outer shell 2 can be easily disassembled and the probe body 1 can be replaced.

[0028] like Figure 2-Figure 3 The bottom of the lower shell 3 can be sealed by the sealing piece 12 at the bottom of the double-sided adhesive ring 11, thereby improving the protection of the probe body 1.

[0029] In this embodiment, during daily use of the probe body 1, the outer shell 2 needs to be installed on the probe body 1 by threaded installation, and then the lower shell 3 is lowered and installed on the outer shell 2 through the cooperation of the L-shaped connector 9 and the connecting groove 7. This can form all-round protection for the probe body 1 and reduce the contact of the probe body 1 with the external environment;

[0030] When using the probe body 1, first tear off the sealing piece 12, and then stick the lower shell 3 to the surface of the object to be measured through the double-sided adhesive ring 11, so that the probe body 1 is stably placed on the object. This eliminates the need for the operator to hold the probe body 1, indirectly improving the convenience of using the thickness gauge (the probe body 1 used in this embodiment is an electromagnetic ultrasonic probe, which can perform contactless detection with the object). Similarly, when the probe body 1 needs to be replaced for detection, the probe body 1 and the outer shell 2 can be removed from the lower shell 3 by rotating the outer shell 2, and then the probe body 1 and the outer shell 2 can be disassembled and replaced with a new probe body 1 by rotating the thread, and then the new probe body 1 is placed in the detection position by connecting the outer shell 2 to the lower shell 3. This can avoid the detection position being changed due to the replacement of the probe body 1, thereby ensuring the detection effect.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
