Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a key mechanism, a key probe and an ultrasonic device. Background Art

[0002] Ultrasonic diagnosis has become increasingly important in the medical field. In the ultrasonic examination rooms of hospitals in China, there are long queues for ultrasonic examinations. Therefore, improving the convenience and diagnostic efficiency of ultrasonic devices has become a new requirement for major ultrasonic devices. For an ultrasonic key probe, since a key is added to the handle end of the sound head, a doctor can operate the sound head with one hand and save the image result, thus greatly improving the diagnostic efficiency. However, at the same time, the key probe needs to meet the IPX7 waterproof requirement. The key destroys the integrity of the housing, making sealing difficult, especially the installation and sealing of side keys.

[0003] As Figures 1-3 shown, a key probe is disclosed in the prior art, which includes a front key 01, a side key 02, a first housing 03, a second housing 04, a sheath 05 and a sound head 06. The first housing 03 and the second housing 04 are assembled up and down to form a housing. The front key 01 is installed above the first housing 03, and the side key 02 is installed between the first housing 03 and the second housing 04. During assembly, the front key 01 and the first housing 03 are pre-assembled into an upper cover assembly first, and the side key 02, the second housing 04, the sheath 05 and the sound head 06 are pre-assembled into a lower cover assembly. Then, the upper cover assembly and the lower cover assembly are sealed by gluing.

[0004] Wherein, half of the assembly parts are respectively provided on the first housing 03 and the second housing 04, and the two assembly parts cooperate together to form an overall assembly space for accommodating the side key 02. Generally, the side key 02 is made of silicone soft material. To ensure the sealing reliability between it and the first housing 03 and the second housing 04, an interference fit is required between the side key 02 and the first housing 03 and the second housing 04. At the same time, it is necessary to ensure that the glue on the surface of the side key 02 and its sealing surfaces with the first housing 03 and the second housing 04 cannot be scraped off during the assembly process, otherwise the sealing will fail. Therefore, this structure has extremely high requirements for the assembly between the housings and the key sealing operation, and the sealing reliability is relatively low.

[0005] To solve this problem, as Figures 4-5As shown, in the prior art, a button probe is also disclosed, which only sets an assembly space for assembling the side button 02 on the second housing 04. However, when the second housing 04 is disassembled, the outer surface of the second housing 04 is provided with a mounting hole for mounting the side button 02, and a surrounding rib 07 is also made around the outside of the mounting hole on the second housing 04. In this way, during assembly, the side button 02 can be first inserted into the mounting hole from the side and pre-assembled and sealed with the second housing 04, reducing the difficulty and risk of button sealing. Moreover, the first housing 03 and the second housing 04 can be processed according to the traditional rabbet sealing method, and the operation is simple. However, since the side button 02 is located at the parting surface of the first housing 03 and the second housing 04, there is an undercut on the outer appearance surface of the upper half surrounding rib of the second housing 04, and a lifter must be added for demolding, resulting in a high mold cost. And after the outer shell assembly is completed, there will be an appearance parting line 08 on the surrounding rib mating surface of the handle, which will damage the appearance of the button probe and affect the aesthetics and feel.

Detailed implementation mode

[0057] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0058] Below in conjunction with Figures 6-11 , describe the embodiments of the present utility model.

[0059] According to an embodiment of the present utility model, in a first aspect, a button mechanism is provided, including: a first housing 1, on which a first assembly part 101 is provided; a second housing 2, which is separately provided from the first housing 1, an installation structure is provided inside the second housing 2, a first installation space 301 with an opening on one side is provided on the installation structure, a second assembly part 201 that cooperates with and is connected to the first assembly part 101 is provided on the second housing 2, and the second assembly part 201 is located outside the installation structure; a side button 4, which is hermetically arranged in the first installation space 301.

[0060] By providing an installation structure inside the second housing 2, and a first installation space 301 with an opening on one side is provided on the installation structure, the side button 4 can be hermetically arranged in the first installation space 301 through the opening, so that the side button 4 only needs to be hermetically assembled with the installation structure, which is convenient to operate, improves the sealing reliability. At the same time, since the side button 4 is hermetically arranged on the installation structure inside the second housing 2, there is no need to provide a surrounding rib on the surface of the second housing 2, and the problem of difficult demolding of the surrounding rib is also avoided.

[0061] Here, the inside and outside refer to the direction perpendicular to the paper surface. The side close to the outside of the paper surface is the outside, and the side extending into the paper surface is the inside.

[0062] Such as Figure 6As shown in the figure, the first housing 1 in this embodiment is arranged above, the second housing 2 is arranged below, and the side button 4 is arranged on one side of the second housing 2. After the first housing 1 and the second housing 2 are assembled, they form the outer shell of the button mechanism. When the assembly is completed, the outer surface of the side button 4, the outer surface of the first assembly part 101, and the outer surface of the second assembly part 201 are in the same plane, ensuring the aesthetic appearance. As a transformable implementation method, it can also be that the first housing 1 is arranged below and the second housing 2 is arranged above.

[0063] As Figure 9 shown, the installation structure in this embodiment includes two installation bodies 3 arranged at intervals, and the two installation bodies 3 are provided with relatively arranged first installation spaces 301. Specifically, the first installation space 301 is an installation groove, and an opening is provided above the installation groove. By setting the installation structure to include two installation bodies 3 arranged at intervals, and the two installation bodies 3 are provided with relatively arranged first installation spaces 301, it is convenient to assemble the side button 4 into the first installation space 301. As a transformable implementation method, it can also be that the installation structure includes one installation body 3, the installation body 3 is provided with a first installation space 301, and the first installation space 301 is an installation groove, and the size of the installation groove is slightly larger than the size of the structure of the side button 4 that cooperates with it. As a transformable implementation method, it can also be that along the circumference of the side button 4, the installation structure includes three installation bodies 3 arranged at intervals, or more installation bodies 3, to support multiple parts of the side button 4.

[0064] As Figure 10 shown, the side button 4 includes: a button body 401 arranged in the first installation space 301; a pressing part 402 protruding outward from the button body 401, and the pressing part 402 is arranged between the first assembly part 101 and the second assembly part 201. During assembly, the side button 4 can be assembled downward through the opening above, so that the button body 401 is arranged in the first installation space 301 and the pressing part 402 is arranged outside the first installation space 301. By arranging the button body 401 of the side button 4 in the first installation space 301 and the pressing part 402 between the first assembly part 101 and the second assembly part 201, while ensuring the sealed assembly of the side button 4, it is convenient for pressing operation.

[0065] Since the button body 401 of the side button 4 is hermetically arranged in the first installation space 301, and its pressing part 402 needs to be exposed outside, therefore, the first assembly part 101 and the second assembly part 201 in this embodiment are relief grooves, and the two relief grooves together form a relief space for the pressing part 402 of the side button 4, facilitating the assembly of the pressing part 402. Specifically, as Figure 7As shown, each relief groove is a semi-circular groove, and the two semi-circular grooves together form a relief space that matches the shape of the pressing portion 402. Of course, in other embodiments, the relief groove can also be of other shapes, as long as it matches the shape of the pressing portion 402.

[0066] To facilitate the assembly of the button body 401 into the first installation space 301, as Figure 9 shown, the installation structure in this embodiment includes a positioning structure 302. The positioning structure 302 is provided on the inner side of the first installation space 301 and can play a certain positioning role when the side button 4 is assembled into the first installation space 301, improving the assembly efficiency. Specifically, the positioning structure 302 is a rib extending inward from the inner wall of the first installation space 301. As an alternative embodiment, it is also possible not to provide the positioning structure 302.

[0067] The side button 4 in this embodiment is bonded in the first installation space 301, which is convenient for the sealed assembly of the side button 4 and the second housing 2, improving the reliability of the seal. Specifically, the button body 401 of the side button 4 is glued in the first installation space 301. As an alternative embodiment, it is also possible that the button body 401 is bonded in the first installation space 301 by other adhesives to achieve a sealed connection.

[0068] Since the positioning structure 302 is a rib extending inward from the inner wall of the first installation space 301, therefore, the recessed part of the first installation space 301 relative to the rib can also be used as a glue storage space, and the glue storage space can store the excess glue to ensure the seal after the side button 4 is assembled.

[0069] During installation, the first installation space 301 can be filled with adhesive first, and then the button body 401 of the side button 4 can be inserted into the first installation space 301 from the opening of the first installation space 301. The adhesive is generally a viscous paste, not a liquid. The overflowing glue can be stored in the glue storage space. If the glue in the glue storage space overflows outward, it can be cleaned up with a cotton swab. For places where the bonding is not in place, additional glue can be applied.

[0070] As Figure 10 and Figure 11As shown in the figure, the installation structure in this embodiment is provided with a second installation space 303. The second installation space 303 is arranged inside the first installation space 301 and is communicated with the first installation space 301. The button mechanism includes a control board 5. The control board 5 is electrically connected to the side button 4 and is arranged in the second installation space 303. Specifically, the second installation space 303 is an installation groove. By providing the second installation space 303 on the installation structure, it is convenient to place the control board 5 connected to the side button 4, and the second installation space 303 is communicated with the first installation space 301, which is convenient for the electrical connection between the control board 5 and the side button 4.

[0071] Generally, before the side button 4 and the control board 5 are assembled with the installation structure, they have been pre-assembled as a whole. Therefore, as Figure 11 shown in the figure, the positioning structure 302 in this embodiment is arranged in the second installation space 303, and the pre-assembled whole of the side button 4 and the control board 5 can be positioned. As a changeable implementation manner, it can also be that the positioning structure 302 is arranged in the first installation space 301, or the positioning structure 302 is arranged in both the first installation space 301 and the second installation space 303.

[0072] As Figure 10 shown in the figure, the first installation space 301 and the second installation space 303 are in a stepped shape.

[0073] As Figure 10 and Figure 11 shown in the figure, a first sealing surface 304 is formed on the outer surface of the installation structure in this embodiment, and a second sealing surface connected to the first sealing surface 304 is provided on the first housing 1. By forming the first sealing surface 304 on the outer surface of the installation structure and providing the second sealing surface connected to the first sealing surface 304 on the first housing 1, it is convenient for the sealing assembly of the first housing 1 and the second housing 2.

[0074] Specifically, the first sealing surface 304 and the second sealing surface are adhesively sealed. During assembly, first apply glue on the first sealing surface 304, then bond the second sealing surface to the glue on the first sealing surface 304, and remove the excess overflow glue. As a changeable implementation manner, it can also be that the first sealing surface 304 and the second sealing surface are bonded by other adhesives.

[0075] For the button mechanism in this embodiment, by arranging the installation structure in the second housing 2, the side button 4 can be completely installed on the installation structure, ensuring the sealing reliability of the side button 4. Moreover, there is no need to set a rib on the second housing 2, which will not change the original part separation method of the outer shell, will not affect the appearance structure of the first housing 1 and the second housing 2, and ensures the aesthetic appearance.

[0076] According to an embodiment of the present utility model, in a second aspect, there is also provided a key probe, comprising: the above-mentioned key mechanism; a sheath 6 provided on one side of the key mechanism; and a sound head 7 provided on the other side of the key mechanism.

[0077] According to an embodiment of the present utility model, in a third aspect, there is also provided an ultrasonic device, comprising: a main body part; and an operation part connected to the main body part, wherein the above-mentioned key probe is provided on the operation part.

[0078] Although the embodiments of the present utility model have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations all fall within the scope defined by the appended claims.
