Description

Technical Field

[0001] This utility model relates to the field of ultrasonic transducer technology, specifically to an ultrasonic transducer housing structure. Background Technology

[0002] Ultrasonic transducers, as devices capable of converting electrical energy into ultrasonic mechanical energy or vice versa, play a vital role in modern science and technology. With the continuous development of ultrasonic technology, the performance requirements for ultrasonic transducers are also increasing. The housing structure, as a crucial part protecting and supporting the internal components of the ultrasonic transducer, directly affects the overall performance, reliability, and service life of the transducer.

[0003] In some applications, ultrasonic transducers may come into contact with liquids such as water and oil, or impurities such as dust. The connections in the housing and cable interfaces are prone to leaks. If the seal is inadequate, external moisture, dust, or other conductive impurities may enter the wiring points and accumulate on the wire connectors or circuit boards. Under certain conditions, these impurities may reduce the insulation performance between different circuits, leading to short circuits, damaging the electrical components of the ultrasonic transducer, and potentially causing more serious electrical failures such as equipment burnout or fires. Therefore, we propose an ultrasonic transducer housing structure. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic transducer housing structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic transducer housing structure, comprising:

[0006] The housing, the top cover on the top of the housing, the connecting plate on the top of the top cover, and the transducer body inside the housing;

[0007] A sealing assembly is disposed on top of a connecting plate. The sealing assembly includes an annular plate disposed on top of the connecting plate, a rack disposed on the annular plate, a first rotating shaft rotatably connected to the annular plate, an arc-shaped rod connected to the first rotating shaft, a clamping plate connected to the arc-shaped rod, a groove being formed on the clamping plate, a fixing ring disposed on top of the connecting plate, and a second rotating shaft rotatably connected between the fixing ring and the connecting plate, the fixing ring being connected to the second rotating shaft.

[0008] A power assembly is located on top of a connecting plate. The power assembly includes a gear disposed on the top of the connecting plate, a fixed shaft disposed on the gear, a motor disposed on top of the fixed shaft, the output end of the motor being fixedly connected to the fixed shaft, and the gear meshing with a rack.

[0009] Furthermore, a limiting component is provided on the top side of the connecting plate near the annular plate. The limiting component includes a first slider. A groove is provided on the top side of the connecting plate near the first slider, and the first slider is slidably connected in the groove.

[0010] The above technical solution is adopted: by setting a limiting component, the annular plate is limited and fixed to prevent displacement during rotation.

[0011] Furthermore, a threaded section is provided on the top of the housing near the top cover, and the top cover is threadedly connected to the housing.

[0012] The above technical solution allows for easy opening of the housing by setting a top cover and threaded sections.

[0013] Furthermore, an auxiliary component is provided inside the housing on the side near the transducer body. The auxiliary component includes a first spring, which contains a first damping element, and a limit plate is provided on the side of the first spring near the transducer body.

[0014] The above technical solution is adopted: by setting auxiliary components, the two sides of the ultrasonic transducer are buffered and damped to prevent the impact force generated by external vibration from acting on the transducer.

[0015] Furthermore, two auxiliary components are provided, which are located on opposite sides of the transducer body, and the end of the first spring away from the limiting plate is fixed to the inner wall of the housing.

[0016] The above technical solution enhances the buffering and shock absorption effect through the above settings.

[0017] Furthermore, a base is provided inside the housing on the side near the transducer body, and a slot is provided on the top of the base.

[0019] Furthermore, a buffer assembly is provided at the bottom of the base. The buffer assembly includes a slide rail, a second slider is slidably connected in the slide rail, a second spring is connected to the second slider, a second damping is provided in the second spring, and a connecting rod is connected to the top of the second damping. The connecting rod is connected to the bottom of the base.

[0020] The above technical solution is adopted: by setting up a buffer component, the bottom of the transducer is buffered and damped.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting a sealing component to seal the wiring joint, external moisture, dust, and conductive impurities can be effectively prevented from entering the wiring joint, thus preventing short circuits between different lines. This solves the problem that in some application scenarios, ultrasonic transducers may come into contact with liquids such as water and oil, or impurities such as dust. The connection points of the outer casing and cable interfaces are prone to poor sealing. If the seal is not tight, external moisture, dust, or other conductive impurities may enter the wiring joint and accumulate on the wire connectors or circuit boards. Under certain conditions, these impurities may reduce the insulation performance between different lines, leading to short circuits, damaging the electrical components of the ultrasonic transducer, and even causing more serious electrical failures such as equipment burnout or fires.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] like Figures 1-3 As shown, this utility model provides a technical solution: an ultrasonic transducer housing structure, comprising:

[0038] The housing 1, the top cover 2 provided on the top of the housing 1, the connecting plate 3 provided on the top of the top cover 2, and the transducer body 7 provided inside the housing 1. A threaded section is provided on the top of the housing 1 near the top cover 2, and the top cover 2 is threadedly connected to the housing 1.

[0039] A sealing assembly 4 is placed on top of the connecting plate 3. The sealing assembly 4 includes an annular plate 41 on top of the connecting plate 3, a rack 42 on the annular plate 41, a first rotating shaft 43 rotatably connected to the annular plate 41, an arc-shaped rod 44 connected to the first rotating shaft 43, a clamping plate 45 connected to the arc-shaped rod 44, a groove 12 on the clamping plate 45, a fixing ring 46 on top of the connecting plate 3, and a second rotating shaft 47 rotatably connected between the fixing ring 46 and the connecting plate 3. The fixing ring 46 is connected to the second rotating shaft 47.

[0040] The power assembly 5 is located on the top of the connecting plate 3. The power assembly 5 includes a gear 51 located on the top of the connecting plate 3. A fixed shaft 52 is provided on the gear 51. A motor 53 is provided on the top of the fixed shaft 52. The output end of the motor 53 is fixedly connected to the fixed shaft 52. The gear 51 is meshed with the rack 42.

[0041] Specifically, the wire is first connected from the interface, and then the motor 53 is turned on to drive the fixed shaft 52 and the gear 51 on it to rotate. The gear 51 drives the rack 42 and the ring plate 41 to rotate. While the ring plate 41 is rotating, it will drive the clamping plate 45 to close through the first rotating shaft 43 and the second rotating shaft 47. Then the wire will be clamped and fixed inside the groove 12, and the gap will be completely blocked to prevent external dust from entering the inside of the housing 1.

[0042] Furthermore, such as Figure 3As shown: An auxiliary component 8 is provided inside the housing 1 on the side near the transducer body 7. The auxiliary component 8 includes a first spring 81, a first damper 82 is provided inside the first spring 81, and a limit plate 83 is provided on the side of the first spring 81 near the transducer body 7. There are two auxiliary components 8, which are located on the two sides of the transducer body 7 respectively. The end of the first spring 81 away from the limit plate 83 is fixed to the inner wall of the housing 1. When the impact force generated by external vibration acts on the housing 1, the first spring 81 and the internal damper 82 will contract to offset and absorb the impact force to protect the transducer.

[0043] The above solutions also have the problem that, while the annular plate 41 is rotating, the lack of a limiting mechanism can easily lead to positional deviation, such as... Figure 2 As shown: A limiting component 6 is provided on the top side of the connecting plate 3 near the annular plate 41. The limiting component 6 includes a first slider 61. A groove 62 is provided on the top side of the connecting plate 3 near the first slider 61. The first slider 61 is slidably connected in the groove 62. When the annular plate 41 rotates, it will be limited by the groove 62 and the first slider 61, so that it will only rotate in place.

[0044] The above solutions also have the drawback that, when vibration occurs, the lack of shock absorption at the bottom of the super-energy device may cause damage, such as... Figure 4 As shown: A buffer assembly 9 is provided at the bottom of the base 10. The buffer assembly 9 includes a slide rail 91. A second slider 92 is slidably connected in the slide rail 91. A second spring 93 is connected to the second slider 92. A second damper 94 is provided in the second spring 93. A connecting rod 95 is connected to the top of the second damper 94. The connecting rod 95 is connected to the bottom of the base 10. When vibration occurs, the base 10 will drive the connecting rod 95 and the second slider 92 at the bottom to slide in the slide rail 91. While sliding, it will squeeze the second spring 93 and the second damper 94 inside, thereby offsetting and buffering the impact force.

[0045] Furthermore, such as Figure 3 As shown: A base 10 is provided inside the housing 1 on the side near the transducer body 7. A slot 11 is provided on the top of the base 10. By setting the base 10 and the slot 11, the transducer can be placed on top of it for positioning.

[0046] The working principle provided by this utility model is as follows: Figures 1-4As shown: First, unscrew the top cover 2 from the top of the housing 1 through the threaded section. Place the super-powered device in the slot 11 on the base 10 inside the housing 1. Then connect the wire, allowing the wire to protrude from the connection point. Then screw the top cover 2 back on. When the external device vibrates and generates an impact force, the base 10 will drive the bottom connecting rod 95 and the second slider 92 to slide in the slide rail 91. While sliding, it will squeeze the second spring 93 and the internal second damper 94, thereby offsetting and buffering the impact force. Then, turn on the motor 53 to drive the fixed shaft 52 and the gear 51 on it to rotate. The gear 51 drives the rack 42 and the annular plate 41 to rotate. When the annular plate 41 rotates, it will be limited by the slide groove 62 and the first slider 61, so that it will only rotate in place. While the annular plate 41 rotates, it will drive the clamping plate 45 to close through the first rotating shaft 43 and the second rotating shaft 47. Then the wire will be clamped and fixed inside the groove 12, and the gap will be completely blocked to prevent external dust from entering the housing 1.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced.
