Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a probe core housing and an ultrasonic probe. Background Art

[0002] In the current market environment, ultrasonic radar probes, as key components, play a crucial role in various devices and systems. However, there is a common problem regarding a crucial part of these probes - the probe core. To ensure that the probe core does not rotate unnecessarily after installation, the flange design of its outer shell adopts a non-circular structure. Although this design intention is good, it brings quite a few challenges in the actual production and assembly processes.

[0003] Specifically, since the flange of the probe core outer shell is non-circular, it is necessary to strictly distinguish the assembly direction when assembling the probe core outer shell and the probe core silica gel sleeve. This specific assembly requirement makes it extremely difficult to achieve automated equipment assembly. In the current production line, this assembly process mostly relies on manual operation, which not only leads to low production efficiency but also is prone to errors in manual operation. Once the assembly direction is incorrect, it will directly affect the normal operation of the ultrasonic radar and may even cause equipment failures or safety hazards.

[0004] Therefore, although the non-circular flange design plays a certain role in preventing the probe core from rotating, the assembly problems it brings cannot be ignored. This not only increases the production cost but also may potentially affect the quality and reliability of the product. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to overcome the deficiencies in the related technologies. The utility model provides a probe core housing and an ultrasonic probe.

[0006] The utility model provides the following technical solutions:

[0007] A probe core housing includes a main body, a probe core outer shell, a locking ring, and a limiting member.

[0008] A butt joint pipe orifice is formed on the main body, and a butt joint platform is arranged on the inner wall of the butt joint pipe orifice; a pressing platform is arranged on the outer side of the opening of the probe core outer shell, and the probe core outer shell is inserted into the butt joint pipe orifice, and the pressing platform presses against the butt joint platform; a locking platform is arranged on the inner side of the locking ring, the locking ring is sleeved on the butt joint pipe orifice, and the locking platform presses against the end surface of the pressing platform away from the butt joint platform; the limiting member is arranged on the probe core outer shell, and the limiting member has a first pressing part and a second pressing part, the first pressing part is located between the locking platform and the pressing platform, and the second pressing part is located between the pressing platform and the butt joint platform.

[0009] As a further improvement of the above technical solution, the limiting member includes a limiting tube sleeved on the outer side wall of the pressing platform. First pressing rings and second pressing rings are respectively arranged at two ends of the limiting tube. The first pressing ring forms the first pressing part, and the second pressing ring forms the second pressing part.

[0010] As a further improvement of the above technical solution, the inner diameter of the butt joint pipe orifice far from the main body is larger than the inner diameter of the butt joint pipe orifice close to the main body, and the outer wall shape of the limiting tube matches the inner wall shape of the butt joint pipe orifice.

[0011] As a further improvement of the above technical solution, a sealing ring extends from the first pressing ring in a direction away from the main body.

[0012] As a further improvement of the above technical solution, the sealing ring is conical. The diameter of the end of the sealing ring close to the first pressing ring is larger than the inner diameter of the locking platform, and the diameter of the end of the sealing ring far from the second pressing ring is smaller than the inner diameter of the locking platform.

[0013] As a further improvement of the above technical solution, the inner wall shape of the locking platform matches the outer wall shape of the sealing ring.

[0014] As a further improvement of the above technical solution, a butt joint groove corresponding to the shape of the butt joint pipe orifice is formed in the end face of the locking platform close to the butt joint pipe orifice.

[0015] As a further improvement of the above technical solution, the main body, the probe core housing, and the locking ring are all made of nylon material.

[0016] As a further improvement of the above technical solution, the locking ring and the butt joint pipe orifice are fixedly connected in a form of ultrasonic welding.

[0018] The present utility model further provides an ultrasonic probe, including the probe core housing described in any one of the above.

[0019] Compared with the related art, the beneficial effects of the present utility model are:

[0020] The core detection housing provided by the present utility model demonstrates its unique convenience and efficiency during the installation process. First, we need to precisely install the integrated module of the core detection into the interior of the main body. Subsequently, the limiting member is installed on the outer shell of the core detection; then, the outer shell of the core detection is gently inserted into the docking pipe orifice of the main body. In this step, the pressing platform on the outer shell of the core detection will come into contact with the docking platform inside the docking pipe orifice. The design of the pressing platform cleverly utilizes the mechanical principle, enabling it to drive the second pressing part of the limiting member to press against the docking platform, thereby forming a preliminary fixed structure. Then, we accurately sleeved the locking ring on the docking pipe orifice and ensured that the locking platform on the locking ring was close to and pressed against the first pressing part of the limiting member. At this time, under the pressing force of the locking platform, the first pressing part further presses against the end face of the pressing platform away from the docking platform. This design enables the pressing platform to maintain a stable position when subjected to pressing forces from two directions, thereby realizing the relative fixation between the outer shell of the core detection and the main body. Finally, we fixedly connect the locking ring and the docking pipe orifice in a certain way (such as by snap-fastening, fusion connection, etc.) to ensure the stability and firmness of the entire structure. During this process, the locking platform and the docking platform respectively push and squeeze the first pressing part and the second pressing part, thereby realizing the simultaneous pressing and clamping of the pressing platform in two directions. This design not only improves the connection strength between the outer shell of the core detection and the main body but also makes the entire installation process without the need for cumbersome positioning and alignment of the deflection angle between the outer shell of the core detection and the docking pipe orifice.

[0021] In summary, the core detection housing provided by the present utility model demonstrates extremely high convenience and efficiency during the installation process. The entire installation process does not require complex operation steps and cumbersome positioning and alignment, and can be completed with just a few simple steps. This design not only improves the assembly efficiency of the core detection housing but also facilitates the automation of workpiece assembly, providing strong support for the rapid production of the production line and on-site emergency repair.

[0033] Embodiment 1

[0034] Combined Figure 1 、 Figure 2 As shown, this embodiment provides a core probe housing, including a main body 100, a core probe outer shell 200, a locking ring 300, and a limiting member 400.

[0035] A docking pipe orifice 110 is formed on the main body 100, and a docking platform 120 is provided on the inner wall of the docking pipe orifice 110; a pressing platform 210 is provided on the outer side of the opening of the core probe outer shell 200, the core probe outer shell 200 is inserted into the docking pipe orifice 110, and the pressing platform 210 presses against the docking platform 120; a locking platform 310 is provided on the inner side of the locking ring 300, the locking ring 300 is sleeved on the docking pipe orifice 110, and the locking platform 310 presses against the end surface of the pressing platform 210 away from the docking platform 120; the limiting member 400 is arranged on the core probe outer shell 200, and the limiting member 400 has a first pressing part and a second pressing part, the first pressing part is located between the locking platform 310 and the pressing platform 210, and the second pressing part is located between the pressing platform 210 and the docking platform 120.

[0036] The core probe housing provided in this embodiment demonstrates its unique convenience and efficiency during the installation process. First, we need to precisely install the integrated module of the core probe into the interior of the main body 100. Subsequently, the limiting member 400 is installed on the outer shell of the core probe; then, the core probe outer shell 200 is gently inserted into the docking pipe orifice 110 of the main body 100. In this step, the pressing platform 210 on the core probe outer shell 200 comes into contact with the docking platform 120 inside the docking pipe orifice 110. The design of the pressing platform 210 ingeniously utilizes the mechanical principle, enabling it to drive the second pressing part of the limiting member 400 to press against the docking platform 120, thereby forming a preliminary fixed structure. Then, we accurately sleeved the locking ring 300 on the docking pipe orifice 110 and ensured that the locking platform 310 on the locking ring 300 approached and pressed against the first pressing part of the limiting member 400. At this time, under the pressing force of the locking platform 310, the first pressing part further presses against the end face of the pressing platform 210 away from the docking platform 120. This design enables the pressing platform 210 to maintain a stable position when subjected to pressing forces from two directions, thereby realizing the relative fixation of the core probe outer shell 200 and the main body 100. Finally, we fixedly connect the locking ring 300 and the docking pipe orifice 110 by a certain means (such as snap connection, welding connection, etc.) to ensure the stability and firmness of the entire structure. During this process, the locking platform 310 and the docking platform 120 respectively push and squeeze the first pressing part and the second pressing part, thereby realizing the simultaneous pressing and clamping of the pressing platform 210 in two directions. This design not only improves the connection strength between the core probe outer shell 200 and the main body 100, but also makes the entire installation process without the need for cumbersome positioning and alignment of the deflection angle between the core probe outer shell 200 and the docking pipe orifice 110.

[0037] In summary, the core probe housing provided in this embodiment demonstrates extremely high convenience and efficiency during the installation process. The entire installation process does not require complex operation steps and cumbersome positioning and alignment, and can be completed with just a few simple steps. This design not only improves the assembly efficiency of the core probe housing, but also facilitates the automation of workpiece assembly, providing strong support for the rapid production of the production line and on-site emergency repair.

[0038] In some embodiments, the limiting member 400 includes a limiting tube 410 sleeved on the outer sidewall of the pressing platform 210. First pressing rings 420 and second pressing rings 430 are respectively arranged at two ends of the limiting tube 410. The first pressing ring 420 forms the first pressing portion, and the second pressing ring 430 forms the second pressing portion. Specifically, the limiting member 400 is an elastic member. The limiting tube 410 of the limiting member 400 is sleeved on the sidewall of the pressing platform 210 by machine or manually. The first pressing ring 420 and the second pressing ring 430 can automatically wrap around two end faces of the pressing platform 210. The installation is convenient and the limiting member 400 is not easily detached from the pressing platform 210. Moreover, when the locking platform 310 and the docking platform 120 respectively push and squeeze the first pressing ring 420 and the second pressing ring 430, the first pressing ring 420 and the second pressing ring 430 are squeezed and deformed. On the one hand, the friction between the locking platform 310, the docking platform 120 and the pressing platform 210 can be increased to avoid relative rotation between the core probe housing 200 and the main body 100. On the other hand, the first pressing ring 420 and the second pressing ring 430 being squeezed and deformed will also squeeze the limiting tube 410, thereby improving the connection sealing performance between the docking pipe orifice 110 and the core probe housing 200.

[0039] In some embodiments, the inner diameter of the docking pipe orifice 110 away from the main body 100 is larger than the inner diameter of the docking pipe orifice 110 close to the main body 100. The outer wall shape of the limiting tube 410 matches the inner wall shape of the docking pipe orifice 110, which is convenient for the inverted conical setting of the docking pipe orifice 110 and convenient for the insertion and installation of the limiting tube 410 into the docking pipe orifice 110.

[0040] In some embodiments, a sealing ring 440 extends from the first pressing ring 420 in a direction away from the main body 100, which is convenient for sealing between the core probe housing 200 and the locking ring 300. Moreover, by integrally designing the sealing ring 440 and the limiting member 400, on the one hand, the production efficiency of parts can be effectively improved, and on the other hand, the processes in the assembly process of this embodiment can be reduced to improve the assembly efficiency. Of course, in other embodiments of the present invention, other structures can also be provided between the core probe housing 200 and the locking ring 300 for sealing treatment.

[0041] In some embodiments, the sealing ring 440 is conical. The diameter of the end of the sealing ring 440 close to the first pressing ring 420 is larger than the inner diameter of the locking platform 310, and the diameter of the end of the sealing ring 440 away from the second pressing ring 430 is smaller than the inner diameter of the locking platform 310. By setting the diameter of the end of the sealing ring 440 away from the second pressing ring 430 to be smaller than the inner diameter of the locking platform 310, it is convenient for the end of the sealing ring 440 to pass through the locking platform 310, facilitating installation. By setting the diameter of the end of the sealing ring 440 close to the second pressing ring 430 to be larger than the inner diameter of the locking platform 310, when the locking platform 310 approaches the second pressing ring 430, the locking platform 310 can first squeeze the sealing ring 440, thereby sealing between the core probe housing 200 and the locking ring 300, and the sealing effect is stable and reliable.

[0042] In some embodiments, the inner wall shape of the locking platform 310 matches the outer wall shape of the sealing ring 440, which is convenient for improving the smoothness of the sealing ring 440 penetrating into the locking platform 310 and improving the assembly efficiency.

[0043] In some embodiments, a docking groove 311 corresponding to the shape of the docking pipe orifice 110 is formed on the end face of the locking platform 310 close to the docking pipe orifice 110, which is convenient for the docking installation of the locking ring 300 and the docking pipe orifice 110 and improves the installation efficiency. Of course, in other embodiments of the present utility model, other structures may also be provided on the locking ring 300 to facilitate the docking installation of the locking ring 300 and the docking pipe orifice 110.

[0044] In some embodiments, the main body 100, the core probe housing 200, and the locking ring 300 are all made of nylon material. Nylon, as a polymer material with excellent wear resistance, strength, and elasticity, has a strong structure and long-lasting durability, and also has good impact resistance, enabling it to withstand various external impacts when used in complex environments.

[0045] In some embodiments, in order to ensure the stable connection between the locking ring 300 and the docking pipe orifice 110, an ultrasonic welding technique is used for fixation. This connection method not only ensures the tight combination between the two, but also improves the overall durability and reliability. The ultrasonic welding technique generates heat through high-frequency vibration, causing the contact surface between the locking ring 300 and the docking pipe orifice 110 to reach the melting point instantaneously and quickly cool and solidify under pressure, thereby achieving the firm connection between the two. This connection method is not only easy to operate, but also has a stable and reliable connection effect, and can meet the use requirements in various complex environments.

[0046] In some embodiments, the limiting member 400 is made of silicone material. This material not only has good elasticity and flexibility, ensuring that the limiting member 400 maintains a stable shape and function under various stresses and strains, but also has excellent high-temperature and low-temperature resistance, enabling it to work properly under extreme temperature conditions. In addition, the chemical stability of silicone also enables it to resist the erosion of most chemical substances, ensuring the reliability and durability of the limiting member 400 in various working environments.
