The connection device includes: a pressing block 4, an elastic member 5, a clamping member 6, and a fixing hook 7.

[0034] In the embodiment of the present application, a cavity 3 is provided on the side of the shell of the display device, and the shape of the cavity 3 is preferably a trapezoid, and the cavity 3 forms a first opening 301 on the side of the shell. The pressing block 4 is placed in the cavity 3 through the first opening 301, and one end of the pressing block 4 close to the first opening 301 is the outer end, and the other end is the inner end. The pressing block 4 has a shape that matches the cavity 3, and there is a distance between the pressing block 4 and the first opening 301.

[0035] Furthermore, an elastic member 5 is provided between the inner end of the pressing block 4 and the inner side surface of the cavity 3. It should be noted that the inner side surface of the cavity 3 refers to the surface of the cavity 3 away from the first opening. In this way, by pressing, the pressing block 4 can slide freely in the cavity 3 and can automatically reset after the external force is cancelled.

[0036] In addition, the cavity 3 is further provided with a second opening 302 on the bottom surface of the shell, and the opening position of the second opening 302 corresponds to the installation position of the clamping member 6. The clamping member 6 is installed from the second opening 302 to the bottom of the pressing block 4, that is, the clamping member 6 is located in the cavity 3, covering the position of the second opening 302, and the clamping member 6 is provided with a third opening 605, and the positions of the third opening 605 and the second opening 302 are correspondingly arranged.

[0037] Furthermore, one end of the fixing hook 7 is fixed to the mounting surface of the target object 2, and the other end of the fixing hook 7 passes through the third opening 605 and the second opening 302 to be detachably connected to the clamping member 6, and the second opening 302 and the third opening 605 allow the fixing hook 7 to pass through and be pulled out.

[0038] In the embodiment of the present application, the display device 1 includes but is not limited to the display device of the extracorporeal membrane oxygenation device (the entire extracorporeal membrane oxygenation device is not shown in the drawings). Generally, for example, when the display device is not in use or turned off, or when the display device is charging, the display device 1 can be installed on the base of the extracorporeal membrane oxygenation device, such as Figure 7 As shown, at this time, the target object 2 can be the base of the extracorporeal membrane oxygenation device. In clinical use, the display device 1 needs to be placed in a conspicuous position. At this time, the display device 1 can be removed from the base and installed on the upper mobile support frame, such as Figure 8 As shown, the target object may also be a mobile support frame on the upper part of the extracorporeal membrane oxygenation device.

[0039] Due to the setting of the elastic member 5, the pressing block 4 can be pressed to move, and by pressing the pressing block 4, the clamping member 6 is driven to move in the pressing direction, so that the clamping member 6 and the fixing hook 7 are separated, and then the display device 1 is disassembled. During installation, it is only necessary to align the second opening 302 and the third opening 605 of the display device 1 with the fixing hook 7, and then move the display device 1 so that the fixing hook 7 passes through the second opening 302 and the third opening 605 and is clamped with the clamping member 6. The whole process realizes the detachable assembly of the display device 1 onto the target object 2.

[0040] Reference Figure 7 , Figure 8 The connecting device is placed inside the cavity 3 of the shell of the display device 1, which can effectively prevent the pressing block 4 from being pressed by mistake and causing the connecting device to be mistakenly locked; and the detachable clamping arrangement of the clamping piece 6 and the fixing hook 7 can improve the connection reliability of the connecting device. The use of the connecting device of the utility model makes it more convenient to disassemble and use the display device.

[0041] In the existing detachable connection device, the hooks and openings that cooperate with each other will destroy the overall waterproof performance, allowing liquid to flow into the component chamber of the display device from the opening. In a preferred embodiment of the present invention, the cavity 3 and the component chamber 8 of the display device 1 shell are isolated from each other, which can prevent liquid from entering the component chamber of the display device 1 from the second opening 302, thereby achieving a waterproof effect.

[0042] In a preferred embodiment of the present invention, in order to further improve the connection reliability of the connecting device, the clamping part 6 includes an adapter portion 601, a step portion 602 and a clamping portion 603, the third opening 605 is arranged on the adapter portion 601, the adapter portion 601 is fixed to the bottom of the pressing block 4, that is, the adapter portion 601 is fixed to the side of the pressing block 4 close to the second opening 302, the step portion 602 is arranged at one end of the adapter portion 601 close to the first opening 301, and the step portion 602 extends toward the bottom surface of the shell, the step portion 602 abuts against the second opening 302, and the other end of the adapter portion 601, that is, the end away from the first opening 301, is provided with a clamping portion 603, and the clamping portion 603 extends in the opposite direction of the step portion 602 and further extends into the cavity 3.

[0043] The fixing hook 7 includes a fixing portion 701 and a hook portion 702. One side of the fixing portion 701 is fixed to the mounting surface of the target object 2, and the hook portion 702 is arranged on the other side of the fixing portion 701. The hook portion 702 extends into the cavity 3 through the second opening 302 and the third opening 605 and is engaged and adapted with the engaging portion 603. The fixing portion 701 can be fixed to the mounting surface of the target object by screws, or by integral molding, welding, or the like.

[0044] It should be noted that the step portion 602 extends to abut against the outer side of the second opening 302. When the elastic force of the elastic member is released, it can limit the pressing block when it moves toward the outside of the cavity; the longitudinal width of the hook portion 702 matches the longitudinal width of the third opening 605, so that the display device 1 is limited in the front and rear directions and cannot fall out in the front and rear directions when in use.

[0045] Reference Figure 4 In a preferred embodiment of the present invention, the clamping portion 603 is provided with a protruding hook toward the hook portion 702, and the protruding hook has a first inclined surface 604 toward the hook portion 702, referring to Figure 6 In 7 (A), the hook portion 702 has a second inclined surface 703 that matches the first inclined surface 604. When the fixing hook 7 passes through the third opening 605, the first inclined surface 604 contacts the second inclined surface 703, so that the second inclined surface 703 pushes the first inclined surface 604, causing the adapter block to drive the pressing block 4 to slide toward the inner side of the cavity 3.

[0046] Reference Figure 5 In another embodiment, the hook portion 702 is further provided with a groove 705 for the clamping portion 603 to clamp, and the clamping portion 603 is provided with a protruding hook that is clamped with the groove 705 toward the hook portion 702, and the protruding hook has a first inclined surface 604 toward the hook portion 702, referring to Figure 67 (B), the hook portion 702 has an arc surface 704. When the fixing hook 7 passes through the third opening 605, the first inclined surface 604 contacts the arc surface 704, so that the arc surface 704 pushes the first inclined surface 604, so that the adapter block drives the pressing block 4 to slide toward the inner side of the cavity 3. The opening direction of the groove 705 is toward the clamping portion 603. The groove 705 can be a through groove or a closed groove, as long as the clamping member 603 can be clamped into 705.

[0047] The surface and line contact between the first inclined surface 604 and the arc surface 704 can achieve a better sliding effect and reduce the probability of getting stuck during the sliding process; Figure 6 In 7 (B), the arc surface 704 on the outer edge of the hook portion 702 is set to be an arc transition, which can reduce the sharpness of the component and avoid scratches on the human body; the clamping through the clamping groove can also provide better clamping strength.

[0048] In a preferred embodiment of the present invention, a receiving groove 401 is provided at the bottom of the pressing block 4, the third opening 605 is smaller than the opening of the receiving groove 401, the adapter portion 601 is fixed on both sides of the receiving groove 401, the clamping portion 603 and the hook portion 702 are placed in the receiving groove 401, and when the pressing block 4 drives the clamping member 6 to move, the size of the third opening 605 allows the clamping portion 603 and the hook portion 702 to disengage.

[0049] In a preferred embodiment of the present invention, one or more guide posts 303 are provided on the inner side of the cavity 3, the pressing block 4 is provided with one or more guide holes 402, the elastic member 5 is sleeved on the guide posts 303, the guide posts 303 can be placed in the guide holes 402 accordingly, and the elastic member 5 can be compressed when squeezed by external force in the guide holes 402.

[0050] It should be noted that the guide hole 402 is preferably arranged outside the receiving groove 401; the elastic member 5 can be a spring.

[0051] In a preferred embodiment of the present invention, one, two or more cavities 3 are arranged on the side of the shell, and the connecting devices are arranged one by one corresponding to the cavities 3. Preferably, two cavities 3 are arranged on the side of the shell, and are mirror-distributed along the middle surface of the shell on the upper parts of both sides of the shell of the display device 1.

[0052] The process of installing the display device 1 to the target object 2, at this time, one end of the fixing hook 7 is fixed on the installation surface of the target object 2, and the step portion 602 abuts against the second opening 302, so that the hook portion 702 of the fixing hook 7 passes through the second opening 302, and then when passing through the third opening 605, the fixing hook 7 pushes the clamping portion 603 so that the adapter block drives the pressing block 4 to slide toward the inner side of the cavity 3 and compresses the elastic member 5. When the fixing hook 7 completes the movement, the clamping portion 702 and the clamping portion 603 are adapted to be clamped. The elastic member 5 is not subjected to external force, and restores its elastic deformation to extend outward. The elastic member 5 is released to push the pressing block 4 to slide toward the first opening 301 until the step portion 602 abuts against the second opening 302, and the clamping portion 702 and the clamping portion 603 are clamped and fixed. At this time, the fixing hook 7 cannot be pulled out, and the display device 1 is fixed on the target object 2.

[0053] More specifically, if Figure 6 As shown, when the fixing hook 7 (A) passes through the second opening 302 and then passes through the third opening 605, the second inclined surface 703 passing through the third opening 605 contacts the first inclined surface 604, so that the second inclined surface 703 pushes the first inclined surface 604, so that the adapter block drives the pressing block 4 to slide toward the inner side of the cavity 3 and compresses the elastic member 5. When the fixing hook 7 completes the movement, the entire second inclined surface 703 is located below the raised hook, so that the hook portion 702 and the clamping portion 603 are adapted to be clamped.

[0054] In another embodiment, if Figure 7 As shown, when the fixing hook 7 (B) passes through the second opening 302 and then passes through the third opening 605, the arc surface 705 passing through the third opening 605 contacts the first inclined surface 604, so that the arc surface 705 pushes the first inclined surface 604, so that the adapter block drives the pressing block 4 to slide toward the inner side of the cavity 3 and compresses the elastic member 5. When the fixing hook 7 completes the movement, the clamping portion 603 extends into the groove 705, so that the hook portion 702 and the clamping portion 603 are adapted to be clamped.

[0055] When the device is subjected to impact and vibration, the connecting devices arranged opposite to each other on both sides prevent the connected display device 1 from coming out in the left or right direction; the longitudinal width of the hook portion 702 of the connecting device matches the longitudinal width of the third opening 605, so that the display device 1 cannot come out in the front or rear direction; the hook portion 702 is engaged with the engaging portion 603, so that the display device 1 cannot come out in the up or down direction.

[0056] During the process of the display device 1 being separated from the target object 2, the pressing blocks 4 on both sides are pressed with both hands, the elastic member 5 contracts, and the pressing blocks 4 slide toward the inner side of the cavity 3, thereby driving the adapter block to slide together, thereby driving the clamping portion 603 to be separated from the hook portion 702. At this time, the fixing hook 7 is not clamped by the clamping portion 603 and can be freely pulled out of the cavity 3, thereby separating the display device 1 from the target object 2.

[0057] When the display device 1 is installed or removed to the target object 2, since the pressing block 4 is set in the cavity 3, both hands can be inserted into the cavity 3 to drag the display device 1 or press the pressing block 4, so that the display device 1 can be conveniently and quickly removed or installed.

[0058] The technical effects achieved by this embodiment are:

[0059] Through the connection devices arranged on both sides, the display device 1 after connection cannot be dislodged in the left and right directions. The longitudinal width of the hook portion 702 of the connection device matches the longitudinal width of the third opening 605, so that the display device 1 cannot be dislodged in the front and rear directions. The hook portion 702 is engaged with the engaging portion 603, so that the display device 1 cannot be dislodged in the upper and lower directions. It can be seen that the connection device achieves the technical effect of firm fixation and high reliability. The connection device is arranged in the cavity 3, and the cavity 3 and the component chamber of the display device 1 shell are isolated from each other, achieving the technical effect of waterproofing. The grooves formed by the cavity 3 and the internal pressing block 4 arranged on both sides enable the user to press the pressing block 4 to unlock when separating the display device 1, thereby achieving the effect of convenient disassembly.
