However, the above-mentioned method of preventing the plug from being loosened has poor reliability, the steel wire structure is easily deformed, and the cable is not fully clamped. The cable is easily loosened from the socket when it is dragged at a certain angle or when the dragging force is large. Utility Model Content

[0011] In one of the embodiments, a waist-shaped hole is formed on the second bracket, and the waist-shaped hole extends in a direction perpendicular to the mounting surface. The end of the wire clamp assembly is passed through the waist-shaped hole and can slide along the extending direction of the waist-shaped hole.

[0032] An embodiment of the present application provides a plug anti-loosening structure and a medical device, wherein the medical device includes a plug anti-loosening structure, and the plug anti-loosening structure is used to prevent the plug from loosening from the socket when the plug is plugged into the socket on the medical device, so as to avoid power supply interruption or signal interruption of the medical device, thereby maintaining the normal operation of the medical device.
[0033] The following uses the plug anti-loosening structure in medical equipment as an example to illustrate the structure of the plug anti-loosening structure. This embodiment is only used as an example and does not limit the technical scope of the present application. It is understandable that in other embodiments, the plug anti-loosening structure of the present application is not limited to being used in medical equipment, but can also be used in any electrical equipment to prevent the plug from being loosened from the socket of the connector, and can also be used alone to prevent the plug from being loosened from the socket on the wall when the plug is plugged into the socket on the wall, which is not limited here.
[0034] An embodiment of the present application provides a medical device (not shown in the figure), including a host (not shown in the figure) and a plug anti-loosening structure as shown in Figure 1, wherein the host has a mounting surface (not shown in the figure), a socket is arranged on the mounting surface, one end of the plug is connected to a cable, and the other end is pluggable and plugged into the socket, so that the host can be powered on or transmit data, and the plug anti-loosening structure is connected to the mounting surface, and is used to prevent the plug from being loosened from the socket when the plug is plugged into the socket, so as to avoid sudden power supply interruption or signal interruption of the medical device. The medical device can be an intravascular ultrasound imaging system, an optical coherence tomography scanner, etc.
[0035] Referring to FIG. 1 , FIG. 1 shows a schematic diagram of a plug anti-loosening structure 10 in an embodiment of the present application. The plug anti-loosening structure 10 provided in an embodiment of the present application comprises a bracket assembly 100 and a wire clamp assembly 200, wherein the bracket assembly 100 is fixedly mounted on the mounting surface where the socket 40 is located. The wire clamp assembly 200 is mounted on the bracket assembly 100 to clamp the cable 50 connected to the plug 30 and keep the distance between the plug 30 and the socket 40 unchanged when the plug 30 is plugged into the socket 40, thereby achieving the purpose of preventing the plug 30 from loosening from the socket 40.
[0036] Specifically, in combination with FIG. 1 and FIG. 2, in one embodiment, the bracket assembly 100 includes a first bracket 110 and a second bracket 120 connected to each other, wherein one end of the first bracket 110 can be fixedly mounted on the mounting surface where the socket 40 is located by fasteners such as screws, and the other end is connected to one end of the second bracket 120, and the wire clamp assembly 200 is mounted on the second bracket 120. Preferably, the first bracket 110 and the second bracket 120 are rotatably connected through a rotating shaft, so that the second bracket 120 can rotate from a first position to a second position relative to the first bracket 110 around an axis parallel to the mounting surface. Specifically, a through hole can be opened on both the first bracket 110 and the second bracket 120, and the rotating shaft passes through the through hole, so that the first bracket 110 and the second bracket 120 are rotatably connected.
[0037] So, see Figure 3 , so that when the plug 30 is pulled out from the socket 40 and the cable 50 assembly does not clamp the cable 50 connected to the plug 30, the second bracket 120 can be rotated relative to the first bracket 110 to a position parallel to the installation surface, thereby reducing the occupied space and facilitating the operation of the operator.
[0038] It is understandable that after the second bracket 120 rotates from the first position to the second position relative to the first bracket 110 by an angle, a certain damping can be provided between the second bracket 120 and the first bracket 110 to prevent the second bracket 120 and the first bracket 110 from being able to rotate relative to each other again under a very small external force, thereby preventing the second bracket 120 from still being able to rotate relative to the first bracket 110 and dragging the plug 30 when the plug 30 is inserted into the socket 40. In this embodiment, the second bracket 120 can rotate 180 degrees relative to the first bracket 110. In other embodiments, after the second bracket 120 rotates from the first position to the second position relative to the first bracket 110 by an angle, the two can be fixed by a locking structure. Among them, the first position refers to the position where the second bracket 120 is perpendicular to the installation surface, and the second position refers to the position where the second bracket is parallel to the installation surface after rotating a certain angle, such as 180 degrees.
[0039] Furthermore, in one embodiment, there are two first brackets 110 and two second brackets 120 respectively, and the two first brackets 110 are symmetrically and spaced apart on both sides of the socket 40, each first bracket 110 is connected to a corresponding second bracket 120, one end of the wire clamp assembly 200 is connected to one of the second brackets 120, and the other end is connected to the other second bracket 120, thereby increasing the reliability of the plug 30 being plugged into the socket 40 and avoiding unstable plugging of the plug 30.
[0040] More specifically, please continue to refer to FIG. 2 , the first bracket 110 is in an “L” shape, formed by bending a sheet metal, and includes a fixing portion 111 and a connecting portion 112 that are vertically connected to each other, the fixing portion 111 is fixedly mounted on the mounting surface, one end of the connecting portion 112 is connected to the fixing portion 111, and the other end is rotatably connected to the second bracket 120. By designing the first bracket 110 in an “L” shape, the fixing portion 111 is integrally fitted to the mounting surface of the host, so that the first bracket 110 has a larger contact area with the mounting surface, which can ensure that the first bracket 110 is firmly mounted on the mounting surface and will not fall off the mounting surface.
[0041] Since there are many types of plugs 30, and different types of plugs 30 have different sizes, in order to enable the plug anti-loosening structure 10 provided in the present application to adapt to different types of plugs 30, as a further improvement, the wire clamp assembly 200 is slidably connected to the second bracket 120, so that the wire clamp assembly 200 can be moved and locked in a direction close to or away from the socket 40 under the action of external force, thereby being able to adjust the position of the wire clamp assembly 200 relative to the second bracket 120, and then when the sizes of the plugs 30 are different, the wire clamp assembly 200 can clamp the cable 50 connected to the plug 30, thereby ensuring that plugs 30 of different types or sizes will not loosen from the socket 40.
[0042] In one embodiment, the sliding connection of the wire clamp assembly 200 to the second bracket 120 is realized by the following structure: a waist-shaped hole 121 is provided on the second bracket 120, and the waist-shaped hole 121 extends in a direction perpendicular to the mounting surface. The end of the wire clamp assembly 200 is inserted into the waist-shaped hole 121 and can slide along the extending direction of the waist-shaped hole 121. In order to fix the wire clamp assembly 200 at any position along the extending direction of the waist-shaped hole 121, the end of the wire clamp assembly 200 has a first locking member 210 inserted into the waist-shaped hole 121. The first locking member 210 is a locking screw in this embodiment, and its function is to lock the wire clamp assembly 200 at any position along the extending direction of the waist-shaped hole 121, so that after the position of the wire clamp assembly 200 is adjusted, the distance between the wire clamp assembly 200 and the mounting surface can be kept constant, and the wire clamp assembly 200 is prevented from moving relative to the bracket assembly 100 again, so as to ensure that the plug 30 is prevented from being loosened from the socket 40.
[0043] It is understandable that the structure in which the wire clamp assembly 200 is slidably connected to the second bracket 120 is not limited to the above structure, but may also be other structures. For example, a slide groove extending perpendicular to the mounting surface is opened on one side of the second bracket 120, and the end of the wire clamp assembly 200 is slidably connected in the slide groove, and the wire clamp assembly 200 is locked at any position of the slide groove in its own extension direction by fasteners such as buckles. The above is not specifically limited.
[0044] Thus, through the above configuration, the plug anti-loosening structure 10 provided in the above embodiment has wide applicability. By adjusting the position of the wire clamp assembly 200, it can be used to prevent different types of plugs 30 from loosening from the socket 40. In addition to being applicable to the pin-shaped plug 30 shown in the figure, it is also applicable to Figure 4 The HDMI plug 30 shown and Figure 5 A USB plug 30 is shown.
[0045] Specifically, regarding the structure of the wire clamp assembly 200, please continue to refer to FIG. 2. The wire clamp assembly 200 includes a first clamping member 220 and a second clamping member 230 that are arranged opposite to each other and connected to each other. One side of the first clamping member 220 and one side of the second clamping member 230 together form a clamping position 201. The clamping position 201 is used for the cable 50 to pass through, so that the cable 50 can be locked in the clamping position 201. In some embodiments, the first clamping member 220 and the second clamping member 230 are connected to each other through a second locking member 240 such as a locking screw, specifically, they are connected to each other through two second locking members 240 arranged at intervals, each second locking member 240 is arranged at the end of the first clamping member 220 and the second clamping member 230 and penetrates the first clamping member 220 and the second clamping member 230, so that the first clamping member 220 and the second clamping member 230 can be moved closer to each other to lock the cable 50 in the clamping position 201, or moved away from each other to loosen the cable 50.
[0046] It is understandable that the connection method between the first clamping member 220 and the second clamping member 230 is not limited to the connection through the second locking member 240. In other embodiments, the first clamping member 220 and the second clamping member 230 may be metal springs, and one end of each of the two may be connected to each other in an integral manner. In the initial state, the clamping position 201 formed by the first clamping member 220 and the second clamping member 230 is small (i.e., the gap between the two is small). Under the action of external force, one of the first clamping member 220 and the second clamping member 230 is broken apart and deformed in a restorable manner, and the clamping position 201 formed by the two becomes larger (i.e., the gap between the two becomes larger). At this time, the cable 50 can pass through the clamping position 201. After releasing one of the first clamping member 220 and the second clamping member 230, the clamping position 201 is restored to become smaller under the action of the elastic force. Thus, through the connection between the first clamping member 220 and the second clamping member 230 , the cable 50 can also be securely locked in the clamping position 201 .
[0047] More specifically, in the embodiment shown in Figure 2, the first clamping member 220 and the second clamping member 230 are both sheet structures, the first clamping member 220 has a bending portion 221, and the bending portion 221 is formed by bending a straight sheet structure twice. The second clamping member 230 is a straight sheet structure, and its two ends are respectively connected to a first locking member 210. The space between the first clamping member 220 and the second clamping member 230 at the bending portion 221 (that is, the inner wall of the bending portion 221 and the side of the second clamping member 230 facing the first clamping member 220) together form a clamping position 201. In this embodiment, the inner wall of the bending portion 221 is an arc surface, so that the bending portion 221 is roughly U-shaped. In this way, the shape of the clamping position 201 roughly matches the cross-sectional shape and size of the cable 50. When the cable 50 is inserted into the clamping position 201, the inner wall of the bending portion 221 fits against the outer peripheral surface of the cable 50, thereby firmly locking and fixing the cable 50 in the clamping position 201.
[0048] It is worth noting that the first clamping member 220 may be a straight sheet structure, and the second clamping member 230 may have a bending portion 221, and the inner wall of the bending portion 221 and the side of the first clamping member 220 facing the second clamping member 230 may together form the clamping position 201; or the first clamping member 220 and the second clamping member 230 may both have a bending portion 221, and the bending portions 221 of the two are arranged opposite to each other, and the inner walls of the bending portions 221 of the two may together form the clamping position 201, and the above are not particularly limited.
[0049] It can be seen that the plug anti-loosening structure 10 provided in the present application, through the above-mentioned design, effectively solves the problem that the plug 30 on the medical device or other electrical equipment is easy to loosen, and avoids the risk of dragging the plug 30 out when the device is moved during normal operation, thereby causing the device to lose power and affecting the normal operation of the device; and the plug anti-loosening structure 10 of the present application adjusts the position of the wire clamp assembly 200, so that the anti-loosening structure can be applicable to plugs 30 of different cable 50 diameters and different types and sizes. In addition to being applicable to preventing the loosening of the power plug 30 with a suffix of "pin" from being applied, it can also be extended to preventing the loosening of plugs 30 such as HDMI or USB, and has a wide range of applicability.
[0050] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
[0051] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
