[0030] Reference Figures 1 to 5 As shown, an endoscope dryer connection device provided according to an embodiment of the present application is used to connect an endoscope dryer and an endoscope handle.

[0031] The endoscope dryer connection device includes a support plate 100, a connecting tube 200, a sealing ring 300, and a locking member 400. The support plate 100 is provided with a through hole 110. One end of the connecting tube 200 passes through the through hole 110 and is sealedly connected to a pagoda connector 210. The connecting tube 200 is connected to the high-pressure air gun on the endoscope dryer via the pagoda connector 210. Optionally, the outer diameter of the pagoda connector 210 is set larger than the aperture of the through hole 110 so that the pagoda connector 210 can limit the connecting tube 200 radially along the through hole 110, thereby improving the installation stability of the connecting tube 200.

[0032] The other end of the connecting tube 200 is provided with a plug 220 and a pressing portion 230. The pressing portion 230 is provided to protrude radially from the connecting tube 200 and to surround the connecting tube 200. An elastic member 240 is provided between the pressing portion 230 and the support plate 100. Optionally, the elastic member 240 may be a rubber column, a spring, etc. abutting between the pressing portion 230 and the support plate 100, which will not be described in detail here. The plug 220 protrudes from the side of the pressing portion 230 facing away from the elastic member 240, and the plug 220 can be inserted into the pipe joint 500 on the endoscope handle. Optionally, the plug 220 may be integrally formed with the connecting tube 200, or may be detachably connected to the connecting tube 200, which will not be described in detail here.

[0033] The sealing ring 300 is sleeved over the pipe joint 500 and abuts the pressing portion 230. The outer diameter of the sealing ring 300 is larger than that of the pipe joint 500 and smaller than that of the pressing portion 230. The locking member 400 includes a clamping plate 410 and a pressure plate 420 arranged opposite each other. The clamping plate 410 and pressure plate 420 are connected by a connecting plate 430 and are located on either side of the support plate 100. In other words, the locking member 400 has a semi-enclosed channel-shaped profile, or at least a portion of the locking member 400 has a semi-enclosed channel-shaped profile. The clamping plate 410 can position the pipe joint 500 so that it presses against the sealing ring 300.

[0034] Optionally, the clamping plate 410 is provided with a first connecting portion, and the pipe joint 500 is provided with a second connecting portion, and the first connecting portion and the second connecting portion can be snap-fitted together so that the clamping plate 410 can limit the pipe joint 500. The first connecting portion can be a protruding structure provided on the clamping plate 410, and the second connecting portion can be a groove structure provided on the side wall of the pipe joint 500 corresponding to the protruding structure. The first connecting portion can also be a hollow locking groove provided on the clamping plate 410, and the second connecting portion can be a protruding structure provided on the side wall of the pipe joint 500 that can be inserted into the hollow locking groove.

[0035] Reference Figure 3 and Figure 4 As shown, when the user needs to dry the endoscope, they can first connect the pagoda connector 210 on the connecting tube 200 to the high-pressure air gun on the endoscope dryer, and then align the plug 220 and insert it into the pipe connector 500 on the endoscope handle. The user can then fix the endoscope (i.e., fix the pipe connector 500) and then tighten the pipe connector 500 by following the steps below:

[0036] In the first step, the support plate 100 is squeezed to move the support plate 100 toward the pipe joint 500 and compress the elastic member 240 , thereby causing the sealing ring 300 to press against the end face of the pipe joint 500 under the elastic force of the elastic member 240 .

[0037] In the second step, the locking member 400 is moved so that the pressure plate 420 presses against the support plate 100 and the clamping plate 410 fixes the pipe joint 500. At this time, the elastic force of the elastic member 240 on the support plate 100 causes the support plate 100 to press against the pressure plate 420. The pressure exerted on the pressure plate 420 is transmitted to the clamping plate 410 through the connecting plate 430, so that the clamping plate 410 locks the pipe joint 500. At this time, the pipe joint 500 and the pressing portion 230 press against the sealing ring 300 from both sides of the sealing ring 300, and the pipe joint 500 and the sealing ring 300 remain in a pressed state, thereby realizing a sealed connection between the endoscope dryer and the endoscope.

[0038] After the endoscope is dried, the user moves the clamping plate 410 to unlock the pipe joint 500, and the support plate 100 is reset under the action of the elastic member 240, thereby separating the endoscope dryer and the endoscope.

[0039] It can be understood that by providing the support plate 100, the elastic member 240 and the locking member 400, on the one hand, the user only needs two steps to lock the pipe joint 500 and only one step to unlock the pipe joint 500, the operation is simple and quick, and the plug 220 will not shake and damage the pipe joint 500, while protecting the endoscope, the operation convenience of the connecting device is effectively improved; on the other hand, the clamping plate 410, the connecting plate 430 and the pressing plate 420 of the locking member 400 cooperate to convert the elastic force of the elastic member 240 on the support plate 100 into pressure on the pipe joint 500, so that the pipe joint 500 is pressed against the sealing ring 300, effectively improving the sealing between the endoscope dryer and the endoscope, avoiding leakage of high-pressure gas, and thereby improving the drying efficiency of the endoscope dryer.

[0040] It should be noted that the number of pipe joints 500 on the endoscope handle varies depending on the type of endoscope. Traditional endoscope handles usually have two pipe joints 500, one for aspirating the accumulated internal fluid and the other for water / gas injection. Some complex endoscope handles are provided with three pipe joints 500 to add new functions. Some simple endoscope handles are only provided with one pipe joint 500 to ensure the basic water / gas injection function. The connection device provided in this application can be provided with a corresponding number of connecting tubes 200 according to the number of pipe joints 500 on the endoscope handle to be dried. The following description is based on the example of providing two pipe joints 500 on the endoscope handle. In this case, the number of connecting tubes 200 is correspondingly set to two, and the two connecting tubes 200 are arranged at intervals. The pipe joints 500 connecting the two connecting tubes 200 are locked by the same clamping plate 410. This is specially explained here to avoid misunderstanding.

[0041] Furthermore, the elastic member 240 is configured as a spring, and the spring is sleeved on the connecting pipe 200 .

[0042] The spring is configured as the elastic member 240, which effectively simplifies the structure of the elastic member 240 and reduces the cost of the connecting device. The spring is sleeved on the outer wall of the connecting tube 200, which facilitates the assembly of the elastic member 240 and improves the installation stability of the elastic member 240.

[0043] Reference Figures 1 to 4As shown, it can be understood that the outer wall of the pipe joint 500 is provided with an annular groove 510, and the clamping plate 410 is provided with a U-shaped groove 411, so that the pipe joint 500 can be engaged with the U-shaped groove 411 through the groove 510. Specifically, the U-shaped groove 411 is composed of a circular arc surface and vertical planes on both sides of the circular arc surface. When the user uses the locking member 400, the plate around the U-shaped groove 411 can be inserted into the groove 510, so that the circular arc surface and the bottom wall of the groove 510 are aligned, the vertical planes on both sides of the circular arc surface are tangent to and abut the bottom wall of the groove 510, and the plate around the U-shaped groove 411 is restricted in the groove 510, thereby limiting the position of the pipe joint 500. When two pipe joints 500 are provided, the bottom wall of the groove 510 of one pipe joint 500 is aligned with the circular arc surface, and the other pipe joint 500 is engaged with the plate on both sides of the U-shaped groove 411 through the groove 510.

[0044] By providing a U-shaped groove 411 and utilizing the existing annular clamping groove 510 of the pipe joint 500 to limit the pipe joint 500, the structure of the clamping plate 410 is simplified and the use of the clamping plate 410 is facilitated. At the same time, the contact area between the pressure plate 420 and the pipe joint 500 can be greatly increased, the pressure on the pipe joint 500 is evenly dispersed, and the structural stability of the pipe joint 500 when locked can be improved.

[0045] Reference Figure 1 and Figure 2 As shown, it can be understood that there are two connecting plates 430 and two pressing plates 420. The two connecting plates 430 are symmetrically arranged on both sides of the U-shaped groove 411, and the support plate 100 is located between the two connecting plates 430. The two connecting plates 430 are respectively connected to a pressing plate 420. There is a gap between the two pressing plates 420 for the connecting pipe 200 to pass through. In this case, the locking member 400 has a sleeve-shaped structure with one side being separated.

[0046] By setting two connecting plates 430 and two pressure plates 420, when the user locks the pipe joint 500, the elastic force of the spring acting on the support plate 100 is symmetrically distributed to the clamping plate 410 through the two pressure plates 420, thereby optimizing the static structure of the locking member 400, avoiding fatigue bending or even breakage that may occur when the clamping plate 410 is subjected to unilateral force, and improving the structural rationality of the locking member 400.

[0047] Reference Figure 3 and Figure 4 As shown, it can be understood that the locking member 400 also includes a base plate 440, which is connected to the bottom end of the card plate 410 and extends toward the support plate 100. The base plate 440, the two connecting plates 430 and the two pressure plates 420 are arranged to form a guide groove 441, and the support plate 100 is passed through the guide groove 441 to guide the locking member 400 to slide relative to the support plate 100.

[0048] By setting the bottom plate 440, a guide groove 441 corresponding to the support plate 100 is formed at the bottom of the locking member 400. The user can insert the support plate 100 into the guide groove 441, and the support plate 100 can guide the locking member 400 to move along the length direction of the support plate 100 (in this embodiment, the length direction of the support plate 100 is the vertical direction), and then quickly lock or unlock the pipe joint 500 in the second step, effectively improving the movement stability of the locking member 400 and further improving the convenience of use of the connecting device.

[0049] Furthermore, the clamping plate 410, pressure plate 420, connecting plate 430, and bottom plate 440 are integrally formed sheet metal components, meaning that the locking member 400 is integrally formed using a bending process. Specifically, the connecting plates 430 on either side of the clamping plate 410 and the bottom plate 440 at the bottom of the clamping plate 410 are formed by a single bending process using the clamping plate 410 as a reference. The pressure plate 420, which faces the clamping plate 410, is formed by a secondary bending process using the portion of the connecting plate 430 on the side away from the clamping plate 410.

[0050] Providing the locking member 400 as an integrally formed sheet metal member can effectively improve the overall strength of the locking member 400 , further simplify the structure of the locking member 400 , and reduce the processing cost of the locking member 400 .

[0051] Reference Figure 1 As shown, it can be understood that a first guide portion 413 is provided at one end of the card plate 410 away from the bottom plate 440, and the first guide portion 413 and a chamfered structure or a rounded structure are provided at the opening of the U-shaped groove 411. The first guide portion 413 is used to guide the bottom wall of the card slot 510 into the U-shaped groove 411.

[0052] By providing the first guide portion 413, when the user moves the card plate 410 to lock the pipe joint 500, the first guide portion 413 guides the bottom wall of the card slot 510 into the U-shaped groove 411, thereby avoiding interference between the card plate 410 and the pipe joint 500, thereby avoiding problems such as the card plate 410 getting stuck or the pipe joint 500 being scratched and worn, thereby improving the smoothness of use of the locking member 400.

[0053] Reference Figure 5 As shown, it should be added that a second guide portion 422 is provided at the end of the pressure plate 420, and the second guide portion 422 is used to guide the connecting pipe 200 into the gap between the two pressure plates 420. The characteristics and effects of the second guide portion 422 can be referred to the previous description of the first guide portion 413, and will not be repeated here.

[0054] Reference Figure 1 and Figure 3As shown, it is understood that the support plate 100 is provided with a detachable limiting member 120, which is located below the bottom plate 440 to limit the locking member 400. Optionally, the limiting member 120 can be a screw, a pin, or other component mounted on the support plate 100. When the support plate 100 is a magnetic metal member, the limiting member 120 can also be a magnet adsorbed on the support plate 100. The structure of the limiting member 120 is not specifically limited herein, as long as it can limit the locking member 400.

[0055] When the clamping plate 410 is not locked to the pipe connector 500, the clamping plate 410 falls due to gravity until the bottom plate 440 contacts the stopper 120. The stopper 120 vertically stops the bottom plate 440, thereby stopping the locking member 400 and preventing the locking member 400 from separating from the support plate 100. By providing the stopper 120, the stopper 120 holds the locking member 400 outside the support plate 100, allowing the support plate 100 and the locking member 400 to be used as a single unit. When the user reuses the connection device, there is no need to reinsert the support plate 100 into the guide hole, effectively improving the user experience.

[0056] Reference Figure 1 and Figure 2 As shown, it can be understood that the side wall of the U-shaped groove 411 is provided with a first avoidance portion 412 , which is an arc-shaped hollow structure matching the shape of the pipe joint 500 , and the first avoidance portion 412 is used to avoid the plug 220 .

[0057] By providing the first avoidance portion 412, before the clamping plate 410 locks the pipe joint 500, when the plug 220 is inserted into the pipe joint 500, the first avoidance portion 412 can avoid the pipe joint 500, thereby preventing the pipe joint 500 from being blocked by the clamping plate 410 and unable to connect with the plug 220. When the support plate 100 is squeezed in the first step, the first avoidance portion 412 moves with the clamping plate 410, and the first avoidance portion 412 avoids the pipe joint 500, thereby avoiding interference between the clamping plate 410 and the pipe joint 500, affecting the movement of the clamping plate 410 or affecting the connection between the pipe joint 500 and the plug 220, thereby further improving the structural rationality of the clamping plate 410.

[0058] It should be noted that when two pipe joints 500 are provided, the first avoidance portions 412 can be provided in a one-to-one correspondence with the pipe joints 500. Alternatively, only one first avoidance portion 412 can be provided. In this case, the vertical length of the clamping plate 410 can be reduced, and the existing first guide portion 413 can be used to avoid the pipe joint 500 located above.

[0059] Reference Figure 5As shown, it should be supplemented that the pressing plate 420 is provided with a second avoidance portion 421, which is used to avoid the pagoda connector 210 with a larger outer diameter. The characteristics and effects of the second avoidance portion 421 can be referred to the description of the first avoidance portion 412 above, and will not be repeated here.

[0060] Reference Figure 4 As shown, it can be understood that an annular limiting groove 221 is formed between the plug 220 and the connecting pipe 200 , and the sealing ring 300 is limited in the limiting groove 221 .

[0061] By providing the limiting groove 221 , the limiting groove 221 can clamp the sealing ring 300 to prevent the sealing ring 300 from falling off from the plug 220 , thereby effectively improving the installation stability of the sealing ring 300 .

[0062] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
