Description

Button structure, connectors and endoscope system Technical Field

[0001] This application relates to the field of endoscope technology, and in particular to a button structure, connector and endoscope system. Background Technology

[0002] An endoscope system is a commonly used medical device. It includes an endoscope, a main unit, and a connector for connecting the endoscope and the main unit. The connector typically includes a button; when the connector is inserted into the main unit's connection socket, the button controls the engagement of the latch and the connection socket, allowing for quick insertion and removal of the connector.

[0003] However, due to prolonged use, the buttons may become stuck and unable to reset. Therefore, effectively preventing button sticking is crucial to ensuring the reliability of the connection between the connector and the host. Summary of the Invention

[0004] Therefore, it is necessary to provide a button structure, connector, and endoscope system to address the problem of button jamming and inability to reset.

[0005] The technical solution is as follows:

[0006] Firstly, this application provides a button structure, including:

[0007] The housing has a mounting cavity, and a key hole communicating with the mounting cavity is provided on the housing. A connecting post protrudes from the side wall of the mounting cavity.

[0008] A button, which is movably mounted in the mounting cavity, and one end of the button can pass through the button hole and out of the mounting cavity to form a driving end;

[0009] An elastic arm, one end of which is connected to the end of the button that is away from the driving end;

[0010] A connecting arm is connected to the end of the elastic arm that is away from the button. The connecting arm has a connecting hole for interference fit with the connecting post. At least one relief groove is provided on the edge of the connecting hole, and each relief groove communicates with the connecting hole.

[0011] In the aforementioned button structure, one end of the elastic arm is connected to the button, and the other end is connected to the connecting arm. The connecting hole in the connecting arm is interference-fitted with the connecting post on the housing, allowing the button to reliably connect to the housing via the elastic arm and the connecting arm. Because the elastic arm is elastic, it deforms under pressure when the button is pressed, guiding the button's movement relative to the housing. This allows the button to control the engagement of the latch with the connector socket. When the button is released, the elastic arm returns to its original position, moving the button back to its unforced state. Therefore, the elastic arm in this button structure not only supports the button but also guides its movement, preventing jamming and ensuring reliable connection between the connector and the host, as well as facilitating quick plugging and unplugging of the connector. In addition, since the edge of the connecting hole has a relief groove that communicates with the connecting hole, the relief groove can provide space for the connecting hole to deform and expand. This allows the connecting post to be easily inserted into the connecting hole with a smaller diameter when assembling the button and the housing, and to be reliably connected to the connecting arm through the interference fit with the connecting hole. This makes it easy and convenient to install the button into the housing, thereby effectively reducing the assembly and processing time of the button structure and reducing production costs.

[0012] The technical solution will be further explained below:

[0013] In one embodiment, there are multiple connecting holes and multiple connecting posts. The multiple connecting holes are spaced apart along the extension direction of the connecting arm. The connecting posts are interference-fitted to the connecting holes one by one. At least one clearance groove is provided on the edge of each connecting hole.

[0014] In one embodiment, the connecting hole is a through hole penetrating the connecting arm, and the clearance groove penetrates both sides of the connecting arm;

[0015] And / or, each of the connecting holes has two clearance grooves on its edge, and the two clearance grooves are respectively disposed opposite to each other on both sides of the corresponding connecting hole.

[0016] In one embodiment, the number of elastic arms is at least two, and the at least two elastic arms are spaced apart in the extension direction of the connecting arm.

[0017] Secondly, this application provides a connector including a snap-fit ​​and a button structure as described above. The housing has a snap-fit ​​hole communicating with the mounting cavity. The snap-fit ​​is rotatably mounted in the mounting cavity. One end of the snap-fit ​​is connected to the end of the button facing away from the driving end. The other end of the snap-fit ​​passes through the snap-fit ​​hole and extends out of the mounting cavity to form a snap-fit ​​end. The snap-fit ​​end has a first snap-fit ​​portion for engaging with a connection socket. The snap-fit ​​has a rotating portion rotatably connected to the side wall of the mounting cavity. The snap-fit ​​can rotate around the rotating portion under the drive of the button.

[0018] In the aforementioned connector, one end of the elastic arm connects to the button, and the other end connects to the connecting arm. The connecting hole in the connecting arm is interference-fitted with the connecting post on the housing, allowing the button to reliably connect to the housing via the elastic arm and the connecting arm. Because the elastic arm is elastic, it deforms under pressure when the button is pressed, guiding the button's movement relative to the housing. This allows the button to control the engagement of the latch with the connector socket. When the button is released, the elastic arm returns to its original position, moving the button back to its unforced state. Therefore, the elastic arm in this connector not only supports the button but also guides its movement, preventing jamming and ensuring reliable connection between the connector and the host, as well as facilitating quick plugging and unplugging. In addition, since the edge of the connecting hole has a relief groove that communicates with the connecting hole, the relief groove can provide space for the connecting hole to deform and expand. This allows the connecting post to be easily inserted into the connecting hole with a smaller diameter when assembling the button and the housing, and to be reliably connected to the connecting arm through the interference fit with the connecting hole. This makes it easy and convenient to install the button into the housing, thereby effectively reducing the connector assembly and processing time and reducing production costs.

[0019] In one embodiment, the connector includes an elastic element disposed in the mounting cavity, one end of the elastic element being connected to one end of the latch opposite to the snap-fit ​​end, and the other end being connected to the housing.

[0020] In one embodiment, the housing includes an outer shell and a bracket. The outer shell forms the mounting cavity. The snap-fit ​​hole and the button hole are both opened in the outer shell. The connecting post is disposed in the outer shell. The bracket is fixedly installed in the mounting cavity. The button, the snap-fit, and the elastic arm are all disposed on the same side of the bracket. The bracket has a limiting groove with an opening facing the snap-fit. The end of the elastic element away from the snap-fit ​​passes through the limiting groove and abuts against the bottom wall of the limiting groove.

[0021] In one embodiment, the elastic arm has a limiting post protruding from one side of the bracket, the limiting post being used to abut against the bracket to limit the distance the button can move toward the side closer to the bracket.

[0022] In one embodiment, the buckle has a positioning post protruding on the side facing the bracket, and the end of the elastic element away from the bracket is sleeved on the positioning post;

[0023] And / or, the housing includes a first housing, a second housing, and an end cap, the first housing and the second housing are disposed opposite to each other and are detachably connected, the end cap is detachably sleeved on one end of the first housing and the second housing, the first housing, the second housing and the end cap together form the mounting cavity, the button hole is provided in the first housing, the snap hole is provided in the end cap, and the connecting post protrudes from the inner wall of the first housing.

[0024] Thirdly, this application provides an endoscope system including the connector described above.

[0025] In the aforementioned endoscope system, one end of the elastic arm is connected to the button, and the other end is connected to the connecting arm. The connecting hole in the connecting arm is interference-fitted with the connecting post on the housing, allowing the button to reliably connect to the housing via the elastic arm and the connecting arm. Because the elastic arm is elastic, it deforms under pressure when the button is pressed, guiding the button's movement relative to the housing. This allows the button to control the engagement of the latch and the connector. When the button is released, the elastic arm returns to its original position, moving the button back to its unforced state. Therefore, the elastic arm in this endoscope system not only supports the button but also guides its movement, preventing jamming and ensuring reliable connection between the connector and the main unit, enabling quick connector insertion and removal, and ultimately guaranteeing the reliability of the endoscope system. In addition, since the edge of the connecting hole has a relief groove that communicates with the connecting hole, the relief groove can provide space for the connecting hole to deform and expand. This allows the connecting post to be easily inserted into the connecting hole with a smaller diameter when assembling the button and the housing, and to be reliably connected to the connecting arm through the interference fit with the connecting hole. This makes it easy and convenient to install the button on the housing, thereby effectively reducing the assembly and processing time of the endoscope system and reducing production costs.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] Referring to Figures 1 to 3, an embodiment of this application provides a button structure 100, including a housing 1, a button 2, an elastic arm 3, and a connecting arm 4, wherein:

[0040] The housing 1 has a mounting cavity 1a. A button hole 112 communicating with the mounting cavity 1a is provided on the housing 1. A connecting post 111 protrudes from the side wall of the mounting cavity 1a. The button 2 is movably mounted in the mounting cavity 1a, and one end of the button 2 can pass through the button hole 112 to the mounting cavity 1a to form a driving end. One end of the elastic arm 3 is connected to the end of the button 2 away from the driving end. The connecting arm 4 is connected to the end of the elastic arm 3 away from the button 2. A connecting hole 41 is provided on the connecting arm 4. The connecting hole 41 is used for interference fit with the connecting post 111. At least one clearance groove 42 is provided on the edge of the connecting hole 41. Each clearance groove 42 communicates with the connecting hole 41.

[0041] In the aforementioned button structure 100, one end of the elastic arm 3 is connected to the button 2, and the other end is connected to the connecting arm 4. The connecting hole 41 in the connecting arm 4 is interference-fitted with the connecting post 111 on the housing 1, allowing the button 2 to reliably connect to the housing 1 via the elastic arm 3 and the connecting arm 4. Because the elastic arm 3 has elastic properties, when the button 2 is pressed, the elastic arm 3 can elastically deform under pressure, allowing the button 2 to move relative to the housing 1 under the guidance of the elastic arm 3. This enables the button 2 to control the engagement of the latch with the connector socket. When the button 2 is released from pressure, the elastic arm 3 elastically resets, moving the button 2 to its unforced state, thus achieving a reset. Therefore, the elastic arm 3 in this button structure 100 not only supports the button 2 but also guides its movement, preventing the button 2 from becoming stuck and unable to reset during use. This effectively ensures the reliability of the connection between the connector and the host, and also ensures quick plugging and unplugging of the connector. In addition, since the edge of the connecting hole 41 is provided with a relief groove 42 that communicates with the connecting hole 41, the relief groove 42 can provide a space for the connecting hole 41 to deform and expand. This allows the connecting post 111 to be easily inserted into the connecting hole 41 with a smaller diameter when assembling the button 2 and the housing 1. It can also be reliably connected to the connecting arm 4 through the interference fit with the connecting hole 41, so that the button 2 can be easily and conveniently installed on the housing 1. This effectively reduces the assembly and processing time of the button structure 100 and lowers the production cost.

[0042] Optionally, as shown in Figure 2, the end face of the driving end of button 2 can be provided with raised texture 21 to indicate to the user that this is the location of button 2, avoid accidental touch, and at the same time, enhance the user experience.

[0043] In one embodiment, as shown in Figures 2 and 3, there are multiple connecting holes 41 and multiple connecting posts 111. The multiple connecting holes 41 are spaced apart along the extending direction of the connecting arm 4, and the connecting posts 111 are correspondingly interference-fitted into the connecting holes 41. Each connecting hole 41 has at least one clearance groove 42 on its edge. Thus, the button 2 can be reliably installed on the housing 1 through the cooperation between the connecting posts 111 and the connecting holes 41, ensuring that the button 2 can control the engagement of the latch and the connecting socket, thereby enabling quick insertion and removal of the connector and ensuring reliable connection between the connector and the host.

[0044] Optionally, as shown in Figure 1, the connecting hole 41 is a through hole penetrating the connecting arm 4, and the clearance groove 42 penetrates both sides of the connecting arm 4. Thus, when the connecting post 111 is inserted into the connecting hole 41, the free end of the connecting post 111 passes through the connecting arm 4, making it difficult for the connecting arm 4 to detach from the connecting post 111 when the button 2 is pressed. This effectively ensures the connection between the connecting post 111 and the connecting arm 4, guaranteeing the reliability of the button 2 installation.

[0045] Optionally, as shown in Figure 3, two clearance grooves 42 are formed on the edge of each connecting hole 41, with the two clearance grooves 42 positioned opposite each other on both sides of the corresponding connecting hole 41. In this way, the two clearance grooves 42 provide space for the connecting hole 41 to expand in size on both sides, allowing the connecting post 111 to be quickly inserted into the connecting hole 41, thus facilitating the connection between the button 2 and the housing 1. Furthermore, this ensures sufficient contact area between the connecting post 111 and the inner wall of the connecting hole 41, preventing the clearance grooves 42 from disrupting the interference fit between the connecting post 111 and the connecting hole 41. This effectively guarantees the reliability of the connection between the connecting post 111 and the connecting arm 4, and ensures the reliability of the assembly of the button 2 and the housing 1.

[0046] In one embodiment, as shown in Figures 2 and 3, there are at least two elastic arms 3, which are spaced apart in the extending direction of the connecting arm 4. Thus, the elastic arms 3 not only reliably support the button 2 but also effectively guide it, ensuring that the button 2 reliably returns to its unforced position when no force is applied, effectively preventing the button 2 from becoming stuck.

[0047] Preferably, as shown in Figures 2 and 3, there are two elastic arms 3, which are spaced apart in the extending direction of the connecting arm 4. In this way, the two elastic arms 3 can reliably support the button 2 and effectively prevent the button 2 from getting stuck.

[0048] Referring to Figures 1 to 5, one embodiment of this application provides a connector 200, including a snap fastener 5 and a button structure 100 as described in any of the above embodiments. The housing 1 has a snap fastener hole communicating with a mounting cavity 1a. The snap fastener 5 is rotatably mounted in the mounting cavity 1a. One end of the snap fastener 5 is connected to the end of the button 2 opposite to the driving end. The other end of the snap fastener 5 passes through the snap fastener hole and extends out of the mounting cavity 1a to form a snap-fit ​​end 51. The snap-fit ​​end 51 has a first snap-fit ​​portion 52, which is used to snap-fit ​​with a connector socket. The snap fastener 5 has a rotating portion 54 rotatably connected to the side wall of the mounting cavity 1a, allowing the snap fastener 5 to rotate around the rotating portion 54 under the drive of the button 2.

[0049] In the connector 200 described above, one end of the elastic arm 3 is connected to the button 2, and the other end is connected to the connecting arm 4. The connecting hole 41 in the connecting arm 4 is interference-fitted with the connecting post 111 on the housing 1, which allows the button 2 to be reliably connected to the housing 1 via the elastic arm 3 and the connecting arm 4. Because the elastic arm 3 has elastic properties, when the button 2 is pressed, the elastic arm 3 can elastically deform under pressure, allowing the button 2 to move relative to the housing 1 under the guidance of the elastic arm 3. This allows the button 2 to control the engagement of the latch 5 with the connecting socket. When the button 2 is released from pressure, the elastic arm 3 elastically resets, moving the button 2 to its unforced state, thus achieving a reset. Therefore, the elastic arm 3 in the connector 200 not only supports the button 2 but also guides its movement, preventing the button 2 from becoming stuck and unable to reset during use. This effectively ensures the reliability of the connection between the connector 200 and the host, and also ensures the rapid insertion and removal of the connector 200. In addition, since the edge of the connecting hole 41 is provided with a relief groove 42 that communicates with the connecting hole 41, the relief groove 42 can provide a space for the connecting hole 41 to deform and expand in size. This allows the connecting post 111 to be easily inserted into the connecting hole 41 with a smaller diameter when assembling the button 2 and the housing 1. It can also be reliably connected to the connecting arm 4 through the interference fit with the connecting hole 41, so that the button 2 can be easily and conveniently installed on the housing 1. This effectively reduces the assembly and processing time of the connector 200 and lowers the production cost.

[0050] In one embodiment, as shown in Figures 4 and 5, the connector 200 includes an elastic element 6 disposed in the mounting cavity 1a. One end of the elastic element 6 is connected to the end of the latch 5 opposite to the latching end 51, and the other end is connected to the housing 1. Thus, when the button 2 drives the latch 5 to rotate, the elastic element 6 can elastically deform under the action of the latch 5, so that when the force applied to the button 2 is removed, the elastic element 6 can drive the latch 5 to rotate in the opposite direction in a predetermined direction, thereby driving the latch 5 to return to the state before it was pressed.

[0051] Further, referring to Figures 2, 4, and 5, the housing 1 includes an outer shell 14 and a bracket 15. The outer shell 14 forms a mounting cavity 1a. Both the snap-fit ​​hole and the button hole 112 are formed in the outer shell 14. A connecting post 111 is disposed in the outer shell 14. The bracket 15 is fixedly installed within the mounting cavity 1a. The button 2, the snap-fit ​​5, and the elastic arm 3 are all located on the same side of the bracket 15. A limiting groove 151 with its opening facing the snap-fit ​​5 is provided on the bracket 15. The end of the elastic member 6 facing away from the snap-fit ​​5 passes through the limiting groove 151 and abuts against the bottom wall of the limiting groove 151. Thus, the limiting groove 151 reliably positions the elastic member 6 on the bracket 15, allowing the elastic member 6 to reliably support the snap-fit ​​5. This ensures that when the force applied to the button 2 is removed, the elastic member 6 reliably drives the snap-fit ​​5 back to its snap-fit ​​state with the connector socket, thereby guaranteeing the reliability of the connector 200 structure.

[0052] Optionally, as shown in Figures 4 and 5, a positioning post 53 protrudes from the side of the buckle 5 facing the bracket 15, and the end of the elastic member 6 facing away from the bracket 15 is sleeved on the positioning post 53. This ensures the reliable connection between the elastic member 6 and the buckle 5, thereby guaranteeing that the elastic member 6 can reliably support the buckle 5, so that the buckle 5 can remain engaged with the connector socket when no external force is applied, effectively ensuring the reliable connection between the connector 200 and the host.

[0053] Optionally, as shown in Figures 4 and 5, a limiting post 31 protrudes from the side of the elastic arm 3 facing the bracket 15. The limiting post 31 abuts against the bracket 15 to limit the distance the button 2 can move towards the side of the bracket 15. In this way, the movable travel distance of the button 2 can be limited within the elastic limit of the elastic element 6 by the abutting of the limiting post 31 against the bracket 15, thereby avoiding damage to the elastic element 6 due to the button 2's overtravel. Therefore, this design can effectively ensure the reliability of the connector 200.

[0054] Specifically, as shown in Figures 2, 4, and 5, the outer casing 14 includes a first outer casing 11, a second outer casing 13, and an end cap 12. The first outer casing 11 and the second outer casing 13 are arranged opposite to each other and are detachably connected. The end cap 12 is detachably fitted onto one end of the first outer casing 11 and the second outer casing 13. The first outer casing 11, the second outer casing 13, and the end cap 12 together form a mounting cavity 1a. A button hole 112 is provided in the first outer casing 11, a snap-fit ​​hole is provided in the end cap 12, and a connecting post 111 protrudes from the inner wall of the first outer casing 11. Thus, the connector 200 is easy to assemble and disassemble, which is beneficial for maintenance. When the connector 200 is connected to a connector socket, the end with the end cap 12 can be inserted into the connector socket, allowing the snap-fit ​​end 51 extending from the end cap 12 to snap into the connector socket, thereby ensuring the reliability of the connection between the connector 200 and the connector socket.

[0055] Optionally, the first housing 11 is provided with a first mating part, and the second housing 13 is provided with a second mating part. The first housing 11 is connected to the second housing 13 through a detachable engagement of the first mating part and the second mating part. Schematic, the first mating part may include a hook, and the second mating part may include a groove that engages with the hook.

[0056] Referring to Figures 1 to 5, one embodiment of this application also provides an endoscope system including the connector 200 of any of the above embodiments.

[0057] In the aforementioned endoscope system, one end of the elastic arm 3 is connected to the button 2, and the other end is connected to the connecting arm 4. The connecting hole 41 in the connecting arm 4 is press-fitted with the connecting post 111 on the housing 1, allowing the button 2 to reliably connect to the housing 1 via the elastic arm 3 and the connecting arm 4. Because the elastic arm 3 has elastic properties, when the button 2 is pressed, the elastic arm 3 can elastically deform under pressure, allowing the button 2 to move relative to the housing 1 under the guidance of the elastic arm 3. This enables the button 2 to control the engagement of the latch 5 with the connecting socket. When the button 2 is released from pressure, the elastic arm 3 elastically resets, moving the button 2 to its unforced state, thus achieving a reset. Therefore, the elastic arm 3 in this endoscope system not only supports the button 2 but also guides its movement, preventing the button 2 from becoming stuck and unable to reset during use. This effectively ensures the reliability of the connection between the connector 200 and the host, the rapid insertion and removal of the connector 200, and the overall reliability of the endoscope system. In addition, since the edge of the connecting hole 41 is provided with a relief groove 42 that communicates with the connecting hole 41, the relief groove 42 can provide a space for the connecting hole 41 to deform and expand in size. This allows the connecting post 111 to be easily inserted into the connecting hole 41 with a smaller diameter when assembling the button 2 and the housing 1. It can also be reliably connected to the connecting arm 4 through the interference fit with the connecting hole 41, so that the button 2 can be easily and conveniently installed on the housing 1. This effectively reduces the assembly and processing time of the endoscope system and lowers the production cost.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
