Description

Technical Field

[0001] The present application relates to the technical field of endoscopes, and in particular to a button structure, a connector and an endoscope system. Background Art

[0002] An endoscope system is a commonly used medical device, which includes an endoscope, a host, and a connector for connecting the endoscope and the host. The connector usually includes a button, which is used to control the engagement of the buckle with the connection socket when the connector is plugged into the connection socket of the host, so as to realize the quick plugging and unplugging of the connector.

[0003] However, due to long-term pressing and use, the button may become stuck and unable to reset. Therefore, how to effectively prevent the button from getting stuck becomes the key to ensuring the reliability of the connection between the connector and the host. Summary of the invention

[0004] Based on this, it is necessary to provide a button structure, connector and endoscope system to address the problem of button stuck and unable to be reset.

[0005] The technical solution is as follows:

[0006] In a first aspect, the present application provides a key structure, including:

[0007] A housing, wherein the housing is formed with a mounting cavity, a button hole communicating with the mounting cavity is formed on the housing, and a connecting column is protruded from a side wall of the mounting cavity;

[0008] A button, the button 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 an end of the button away from the driving end;

[0010] A connecting arm, wherein the connecting arm is connected to an end of the elastic arm away from the button, and a connecting hole is provided on the connecting arm, and the connecting hole is used for interference fit with the connecting column, and at least one paving groove is provided on the edge of the connecting hole, and each of the paving grooves is connected to the connecting hole.

[0011] In the above-mentioned key structure, one end of the elastic arm is connected to the key, and the other end is connected to the connecting arm, and the connecting hole in the connecting arm is interference fit with the connecting column on the shell, so that the key can be reliably connected to the shell through the elastic arm and the connecting arm. Among them, because the elastic arm has elastic properties, when the key is pressed, the elastic arm can be elastically deformed under the action of pressing, so that the key can move relative to the shell under the guidance of the elastic arm, so that the key can control the snap-fitting with the connecting socket. When the pressing of the key is canceled, the elastic arm can be elastically reset and drive the key to move to a state when it is not under force to achieve reset. Therefore, the elastic arm in the key structure can not only support the key, but also guide the movement of the key to avoid the situation where the key is stuck and cannot be reset during use, effectively ensuring the connection reliability between the connector and the host, and effectively ensuring the realization of quick plug-in and unplug of the connector. In addition, since a clearance groove connected to the connecting hole is opened on the edge of the connecting hole, the clearance groove can provide a space for the connecting hole to deform and expand in size. This allows the connecting column to be easily inserted into the connecting hole whose aperture is smaller than that of the connecting column when assembling the key and the shell, and can be reliably connected to the connecting arm through an interference fit with the connecting hole, so that the key can be simply and conveniently installed on the shell, thereby effectively reducing the time for assembly and processing of the key structure and reducing production costs.

[0018] In the above connector, one end of the elastic arm is connected to the button, and the other end is connected to the connecting arm, and the connecting hole in the connecting arm is interference fit with the connecting column on the shell, so that the button can be reliably connected to the shell through the elastic arm and the connecting arm. Among them, because the elastic arm has elastic properties, when the button is pressed, the elastic arm can be elastically deformed under the pressing action, so that the button can move relative to the shell under the guiding action of the elastic arm, so that the button can control the snap-fitting with the connecting socket. When the pressing of the button is canceled, the elastic arm can be elastically reset and drive the button to move to a state when it is not under force to achieve reset. Therefore, the elastic arm in the connector can not only support the button, but also guide the movement of the button to avoid the situation where the button is stuck and cannot be reset during use, effectively ensuring the connection reliability between the connector and the host, and effectively ensuring the realization of quick plug-in and unplug of the connector. In addition, since a clearance groove connected to the connecting hole is provided on the edge of the connecting hole, the clearance groove can provide a space for the connecting hole to deform and expand in size. This allows the connecting column to be easily inserted into the connecting hole whose aperture is smaller than that of the connecting column when the key and the shell are assembled, and can be reliably connected to the connecting arm through an interference fit with the connecting hole, so that the key can be simply and conveniently installed on the shell, thereby effectively reducing the time for connector assembly and processing and reducing production costs.

[0019] In one of the embodiments, the connector includes an elastic member, which is disposed in the installation cavity, one end of the elastic member is connected to an end of the buckle away from the clamping end, and the other end is connected to the shell.

[0020] In one embodiment, the shell includes an outer shell and a bracket, the outer shell forms the installation cavity, the buckle hole and the button hole are both opened in the outer shell, the connecting column is arranged on the outer shell, the bracket is fixedly installed in the installation cavity, the button, the buckle and the elastic arm are all arranged on the same side of the bracket, and a limiting groove with an opening toward the buckle is opened on the bracket, and the end of the elastic member facing away from the buckle penetrates into the limiting groove and abuts against the bottom wall of the limiting groove.

[0021] In one of the embodiments, a limiting column is protruded from one side of the elastic arm toward the bracket, and the limiting column is used to abut against the bracket to limit the distance that the button moves toward the side close to the bracket.

[0024] In a third aspect, the present application provides an endoscope system comprising any of the connectors described above.

[0025] In the above-mentioned endoscope system, one end of the elastic arm is connected to the button, and the other end is connected to the connecting arm, and the connecting hole in the connecting arm is interference fit with the connecting column on the shell, so that the button can be reliably connected to the shell through the elastic arm and the connecting arm. Among them, because the elastic arm has elastic properties, when the button is pressed, the elastic arm can be elastically deformed under the pressing action, so that the button can move relative to the shell under the guiding action of the elastic arm, so that the button can control the snap-fitting with the connecting socket. When the pressing of the button is canceled, the elastic arm can be elastically reset and drive the button to move to a state when it is not under force to achieve reset. Therefore, the elastic arm in the endoscope system can not only support the button, but also guide the movement of the button to avoid the situation where the button is stuck and cannot be reset during use, effectively ensuring the connection reliability between the connector and the host, effectively ensuring the realization of quick plug-in and unplug of the connector, and effectively ensuring the reliability of the endoscope system. In addition, since a clearance groove connected to the connecting hole is provided on the edge of the connecting hole, the clearance groove can provide a space for the connecting hole to deform and expand in size.

[0039] See also Figures 1 to 3 , a key structure 100 provided in one embodiment of the present application includes a housing 1, a key 2, an elastic arm 3 and a connecting arm 4, wherein:

[0040] The shell 1 is formed with an installation cavity 1a, and a button hole 112 connected to the installation cavity 1a is opened on the shell 1, and a connecting column 111 is protruded from the side wall of the installation cavity 1a. The button 2 can be movably installed in the installation cavity 1a, and one end of the button 2 can pass through the installation cavity 1a through the button hole 112 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, and the connecting arm 4 is connected to the end of the elastic arm 3 away from the button 2. A connecting hole 41 is opened on the connecting arm 4, and the connecting hole 41 is used for interference fit with the connecting column 111. At least one makeshift groove 42 is opened on the edge of the connecting hole 41, and each makeshift groove 42 is connected to the connecting hole 41.

[0041] In the above-mentioned key structure 100, one end of the elastic arm 3 is connected to the key 2, and the other end is connected to the connecting arm 4, and the connecting hole 41 in the connecting arm 4 is interference-fitted with the connecting column 111 on the housing 1, so that the key 2 can be reliably connected to the housing 1 through the elastic arm 3 and the connecting arm 4. Among them, since the elastic arm 3 has elastic properties, when the key 2 is pressed, the elastic arm 3 can be elastically deformed under the pressing action, so that the key 2 can move relative to the housing 1 under the guiding action of the elastic arm 3, so that the key 2 can control the snap-fitting with the connecting socket. When the pressing of the key 2 is canceled, the elastic arm 3 can be elastically reset, and drive the key 2 to move to a state when it is not under force, so as to achieve reset. Therefore, the elastic arm 3 in the key structure 100 can not only support the key 2, but also guide the movement of the key 2 to avoid the situation that the key 2 is stuck and cannot be reset during use, effectively ensuring the connection reliability between the connector and the host, and effectively ensuring the realization of quick plug-in and unplug of the connector. In addition, since a clearance groove 42 connected to the connecting hole 41 is opened on the edge of the connecting hole 41, the clearance groove 42 can provide a space for the connecting hole 41 to deform and expand in size. This allows the connecting column 111 to easily penetrate into the connecting hole 41 whose aperture size is smaller than that of the connecting column 111 when the key 2 is assembled with the shell 1, and can be reliably connected to the connecting arm 4 through an interference fit with the connecting hole 41, so that the key 2 can be simply and conveniently installed on the shell 1, thereby effectively reducing the assembly and processing time of the key structure 100 and reducing the production cost.

[0042] Optional, such as Figure 2 As shown, the end surface of the driving end of the button 2 may be provided with a convex pattern 21 to remind the user that this is the location of the button 2 to avoid accidental touches and, at the same time, enhance the user's experience.

[0043] In one embodiment, in combination Figure 2 and Figure 3As shown, the number of the connection holes 41 and the number of the connection columns 111 are both multiple, and the multiple connection holes 41 are arranged at intervals along the extension direction of the connection arm 4. The connection columns 111 are interference-connected to the connection holes 41 one by one, and at least one clearance groove 42 is provided at the edge of each connection hole 41. In this way, the key 2 can be reliably mounted on the housing 1 through the cooperation between the connection columns 111 and the connection holes 41, so as to ensure that the key 2 can control the card-fit cooperation between the buckle and the connection socket, so as to realize the quick plug-in and unplug of the connector, and ensure the connection reliability between the connector and the host.

[0044] Alternatively, if Figure 1 As shown, the connection hole 41 is a through hole that penetrates the connection arm 4, and the clearance groove 42 penetrates both sides of the connection arm 4. In this way, when the connection column 111 is inserted into the connection hole 41, the free end of the connection column 111 passes through the connection arm 4, so that when the button 2 is pressed, the connection arm 4 is not easy to fall off from the connection column 111, thereby effectively ensuring the connection between the connection column 111 and the connection arm 4, and ensuring the reliability of the installation of the button 2.

[0045] Optional, such as Figure 3 As shown, two clearance grooves 42 are provided at the edge of each connection hole 41, and the two clearance grooves 42 are arranged on both sides of the corresponding connection hole 41. In this way, the two clearance grooves 42 can provide the connection hole 41 with space for size deformation and expansion on the opposite sides of the connection hole 41, so that the connection column 111 can be quickly inserted into the connection hole 41, thereby conveniently completing the connection between the key 2 and the housing 1. In addition, this can also ensure that the connection column 111 has sufficient contact area with the inner wall of the connection hole 41, so that the opening of the clearance groove 42 will not destroy the interference fit between the connection column 111 and the connection hole 41, effectively ensuring the connection reliability between the connection column 111 and the connection arm 4, and ensuring the reliability of the assembly of the key 2 and the housing 1.

[0046] In one embodiment, Figure 2 and Figure 3 As shown, there are at least two elastic arms 3, and at least two elastic arms 3 are arranged at intervals in the extension direction of the connecting arm 4. In this way, the elastic arms 3 can not only reliably support the key 2, but also effectively guide the key 2 to ensure that the key 2 can reliably return to the position when no force is applied to the key 2, effectively avoiding the key 2 from getting stuck.

[0047] Preferably, Figure 2 and Figure 3 As shown, there are two elastic arms 3, and the two elastic arms 3 are arranged at intervals in the extending direction of the connecting arm 4. In this way, the two elastic arms 3 can not only reliably support the key 2, but also effectively prevent the key 2 from getting stuck.

[0048] See also Figures 1 to 5 An embodiment of the present application provides a connector 200, including a buckle 5 and a key structure 100 of any of the above embodiments. The housing 1 is provided with a buckle hole connected to the mounting cavity 1a. The buckle 5 is rotatably mounted in the mounting cavity 1a. One end of the buckle 5 is connected to the end of the key 2 away from the driving end. The other end of the buckle 5 passes through the mounting cavity 1a through the buckle hole to form a clamping end 51. The clamping end 51 is provided with a first clamping portion 52. The first clamping portion 52 is used to clamp and cooperate with the connection socket. The buckle 5 is provided with a rotating portion 54 rotatably connected to the side wall of the mounting cavity 1a. The buckle 5 can rotate around the rotating portion 54 under the drive of the key 2.

[0049] In the above connector 200, one end of the elastic arm 3 is connected to the button 2, and the other end is connected to the connecting arm 4, and the connecting hole 41 in the connecting arm 4 is interference fit with the connecting column 111 on the housing 1, so that the button 2 can be reliably connected to the housing 1 through the elastic arm 3 and the connecting arm 4. Among them, since the elastic arm 3 has elastic properties, when the button 2 is pressed, the elastic arm 3 can be elastically deformed under the pressing action, so that the button 2 can move relative to the housing 1 under the guiding action of the elastic arm 3, so that the button 2 can control the snap fit between the buckle 5 and the connecting socket. When the pressing of the button 2 is canceled, the elastic arm 3 can be elastically reset and drive the button 2 to move to a state when it is not under force to achieve reset. Therefore, the elastic arm 3 in the connector 200 can not only support the button 2, but also guide the movement of the button 2 to avoid the situation where the button 2 is stuck and cannot be reset during use, effectively ensuring the connection reliability between the connector 200 and the host, and effectively ensuring the realization of quick plug-in and unplug of the connector 200. In addition, since a clearance groove 42 connected to the connecting hole 41 is provided on the edge of the connecting hole 41, the clearance groove 42 can provide a space for the connecting hole 41 to deform and expand in size. This allows the connecting column 111 to easily penetrate into the connecting hole 41 whose aperture size is smaller than that of the connecting column 111 when the key 2 is assembled with the shell 1, and to be reliably connected to the connecting arm 4 through an interference fit with the connecting hole 41, so that the key 2 can be simply and conveniently installed on the shell 1, thereby effectively reducing the assembly and processing time of the connector 200 and reducing the production cost.

[0050] In one embodiment, Figure 4 and Figure 5 As shown, the connector 200 includes an elastic member 6, which is disposed in the mounting cavity 1a, one end of the elastic member 6 is connected to the end of the buckle 5 away from the clamping end 51, and the other end is connected to the housing 1. In this way, when the button 2 drives the buckle 5 to rotate, the elastic member 6 can be elastically deformed under the action of the buckle 5, so that when the force applied to the button 2 is removed, the elastic member 6 can drive the buckle 5 to rotate in the opposite direction of the predetermined direction, and then drive the buckle 5 to return to the state before being pressed.

[0051] Furthermore, combined with Figure 2 , Figure 4 and Figure 5 As shown, the housing 1 includes a shell 14 and a bracket 15, the shell 14 forms a mounting cavity 1a, the buckle hole and the button hole 112 are both provided in the shell 14, the connecting column 111 is provided in the shell 14, the bracket 15 is fixedly installed in the mounting cavity 1a, the button 2, the buckle 5 and the elastic arm 3 are all provided on the same side of the bracket 15, the bracket 15 is provided with a limiting groove 151 with an opening toward the buckle 5, and the end of the elastic member 6 away from the buckle 5 penetrates the limiting groove 151 and abuts against the bottom wall of the limiting groove 151. In this way, the elastic member 6 can be reliably arranged on the bracket 15 by using the limiting groove 151, so that the elastic member 6 can reliably support the buckle 5, so that when the force applied to the button 2 is removed, the elastic member 6 can reliably drive the buckle 5 to return to the state of being engaged with the connection socket, thereby ensuring the reliability of the connector 200 structure.

[0052] Optional, such as Figure 4 and Figure 5 As shown, a positioning column 53 is protruded on one side of the buckle 5 facing the bracket 15, and one end of the elastic member 6 facing away from the bracket 15 is sleeved on the positioning column 53. In this way, the connection reliability between the elastic member 6 and the buckle 5 can be ensured, so that the elastic member 6 can reliably support the buckle 5, so that the buckle 5 can maintain the state of being engaged with the connection socket when no external force is applied, and effectively ensure the connection reliability between the connector 200 and the host.

[0053] Optional, such as Figure 4 and Figure 5 As shown, a limiting column 31 is protruded on one side of the elastic arm 3 facing the bracket 15, and the limiting column 31 is used to abut against the bracket 15 to limit the distance that the key 2 moves toward the side close to the bracket 15. In this way, the movable travel distance of the key 2 can be limited within the elastic limit of the elastic member 6 by the abutment of the limiting column 31 and the bracket 15, thereby avoiding damage to the elastic member 6 due to over-travel movement of the key 2. Therefore, this design can effectively ensure the reliability of the connector 200.

[0054] Specifically, Figure 2 , Figure 4 and Figure 5As shown, the housing 14 includes a first housing 11, a second housing 13 and an end cover 12. The first housing 11 and the second housing 13 are arranged opposite to each other, and the first housing 11 and the second housing 13 are detachably connected. The end cover 12 is detachably sleeved on one end of the first housing 11 and the second housing 13. The first housing 11, the second housing 13 and the end cover 12 jointly form a mounting cavity 1a. The button hole 112 is arranged on the first housing 11, the buckle hole is arranged on the end cover 12, and the connecting column 111 is convexly arranged on the inner wall of the first housing 11. In this way, the connector 200 has the characteristic of being easy to disassemble and assemble, which is conducive to the maintenance of the connector 200. Among them, when the connector 200 is connected to the connection socket, the end where the end cover 12 is located can be used to be inserted into the connection socket, so that the clamping end 51 extending from the end cover 12 can be clamped with the connection socket, thereby ensuring the connection reliability between the connector 200 and the connection socket.

[0055] Optionally, the first housing 11 is provided with a first matching portion, the second housing 13 is provided with a second matching portion, and the first housing 11 is connected to the second housing 13 through detachable matching of the first matching portion and the second matching portion. Schematically, the first matching portion may include a hook, and the second matching portion may include a hook groove matched with the hook.

[0056] See also Figures 1 to 5 An embodiment of the present application further provides an endoscope system, comprising the connector 200 of any of the above embodiments.

[0057] In the above-mentioned 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, and the connecting hole 41 in the connecting arm 4 is interference fit with the connecting column 111 on the housing 1, so that the button 2 can be reliably connected to the housing 1 through the elastic arm 3 and the connecting arm 4. Among them, since the elastic arm 3 has elastic properties, when the button 2 is pressed, the elastic arm 3 can be elastically deformed under the pressing action, so that the button 2 can move relative to the housing 1 under the guiding action of the elastic arm 3, so that the button 2 can control the snap fit between the buckle 5 and the connecting socket. When the pressing of the button 2 is canceled, the elastic arm 3 can be elastically reset and drive the button 2 to move to a state when it is not under force to achieve reset. Therefore, the elastic arm 3 in the endoscope system can not only support the button 2, but also guide the movement of the button 2 to avoid the situation where the button 2 is stuck and cannot be reset during use, effectively ensuring the connection reliability between the connector 200 and the host, effectively ensuring the realization of quick plug-in and unplug of the connector 200, and effectively ensuring the reliability of the endoscope system. In addition, since a clearance groove 42 connected to the connecting hole 41 is provided on the edge of the connecting hole 41, the clearance groove 42 can provide a space for the connecting hole 41 to deform and expand in size. This allows the connecting column 111 to easily penetrate into the connecting hole 41 whose aperture size is smaller than that of the connecting column 111 when the button 2 is assembled with the shell 1, and can be reliably connected to the connecting arm 4 through an interference fit with the connecting hole 41, so that the button 2 can be simply and conveniently installed on the shell 1, thereby effectively reducing the assembly and processing time of the endoscope system and reducing the production cost.

[0058] The technical features of the above embodiments may be combined arbitrarily.
