[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figures 1 to 6 As shown, an embodiment of the utility model provides a connecting mechanism 10, which includes a first shell 100, a locking device 200 and a second shell 300; the first shell 100 is provided with a connected plug-in slot 110 and a mounting hole 120; the locking device 200 includes an adjusting member 210, a limiting ring 220 and a locking block 230, the limiting ring 220 is inserted into the mounting hole 120 and connected to the first shell 100, the locking block 230 is connected to the adjusting member 210 and slidably cooperates with the limiting ring 220, and the adjusting member 210 is used to drive the locking block 230 to move axially along the limiting ring 220; the second shell 300 is plugged and cooperated with the plug-in slot 110; there are at least a locking position and a releasing position on the moving path of the adjusting member 210, in the locking position, the locking block 230 is snap-fitted with the second shell 300, and in the releasing position, the locking block 230 is separated from the second shell 300.

[0036] When using the connecting mechanism 10 of the present embodiment, the second shell 300 is first connected to the first shell 100, and the locking block 230 can be driven to lock and fix with the second shell 300 by rotating the adjusting member 210, thereby realizing the combined fixation of the first shell 100 and the second shell 300; when it is necessary to separate the first shell 100 and the second shell 300, the adjusting member 210 is rotated and moved to the release position, at which time the locking block 230 is separated from the second shell 300, and the second shell 300 can be separated from the first shell 100, with a simple structure and convenient disassembly and assembly.

[0037] In the connecting mechanism 10 of this embodiment, by setting a locking device 200 to cooperate with the first shell 100 and the second shell 300 respectively, quick disassembly and assembly between the first shell 100 and the second shell 300 can be achieved. When the connecting mechanism 10 is used in a plug-in box, convenient disassembly and assembly of multiple plug-in boxes 1 can be achieved. The structure is simple and the use effect is good.

[0038] Specifically, see Figure 3 As shown, the adjusting member 210 includes a rotating shaft 211 and a positioning protrusion 212. The positioning protrusion 212 is protruded on the outer wall of the rotating shaft 211. The rotating shaft 211 is rotatably connected to the limiting ring 220 and the locking block 230 respectively. The limiting ring 220 is provided with a guide groove 221, and the guide groove 221 extends spirally along the axial direction of the limiting ring 220. The positioning protrusion 212 is slidably matched with the guide groove 221.

[0039] In this arrangement, the limit ring 220 is connected to the first shell 100 and is relatively fixed to the first shell 100. When the rotating shaft 211 is driven to rotate relative to the limit ring 220, the positioning protrusion 212 slides with the guide groove 221. Therefore, as the rotating shaft 211 rotates, the rotating shaft 211 can be driven to move axially along the limit ring 220, and finally the locking block 230 can be driven to move toward or away from the second shell 300, so that the locking block 230 locks and releases the second shell 300.

[0040] Specifically, see Figure 4 As shown, the second shell 300 includes a shell body 310 and a plug-in portion 320, the plug-in portion 320 is connected to the shell body 310, and the plug-in portion 320 is plugged into the plug-in slot 110. When in the locked position, the locking block 230 is fixedly connected to the plug-in portion 320, and in the released position, the plug-in portion 320 is separated from the locking block 230.

[0041] In this embodiment, the plug-in portion 320 protrudes from one side of the shell body 310. When the second shell 300 is connected to the first shell 100, the shell body 310 is flush with the outer wall of the first shell 100 and the plug-in portion 320 is inserted into the plug-in slot 110, so that the first shell 100 and the second shell 300 are tightly combined and the outer surface is smooth. In some embodiments, the plug-in portion 320 and the shell body 310 can also be combined in a detachable manner. In this case, the plug-in portion 320 can be made of a material with a higher strength than the shell body 310 to improve the durability of the second shell 300. When the plug-in portion 320 is worn, it can also be replaced separately. For example, the shell body 310 is made of plastic material and the plug-in portion 320 is made of metal material.

[0042] See also Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, a locking portion 3212 is provided on the side wall of the plug-in portion 320 , and a locking groove 231 is provided at one end of the locking block 230 away from the adjusting member 210 . When in the locking position, the locking portion 3212 is engaged with the locking groove 231 .

[0043] According to the arrangement, when the locking block 230 is plugged into the plug-in portion 320, the locking groove 231 can be adapted to the locking portion 3212, so that not only the locking block 230 and the plug-in portion 320 can be tightly combined, but the interaction between the two can also realize the positioning function; in a preferred embodiment, the end of the locking block 230 can be a toothed structure, and a plurality of spaced locking grooves 231 are formed on the locking block 230, and a locking portion 3212 corresponding to the plurality of locking grooves 231 is also provided on the plug-in portion 320. Through the cooperation of the plurality of locking grooves 231 and the locking portion 3212, the bonding strength between the locking block 230 and the plug-in portion 320 can be further improved.

[0044] Specifically, the plug-in portion 320 includes a connecting section 321 and a limiting section 322, the connecting section 321 is respectively connected to the shell body 310 and the limiting section 322, and the limiting section 322 at least partially extends outward along the axial direction parallel to the limiting ring 220; the connecting section 321 is provided with a receiving groove 3211, and when in the locking position, the locking block 230 is inserted into the receiving groove 3211, and the limiting section 322 is at least partially located on the side of the locking block 230 away from the shell body 310.

[0045] When the first shell 100 is connected to the second shell 300, the adjusting member 210 is rotated to move it to the locking position. At this time, the locking block 230 can be located between the limiting section 322 and the shell body 310, so that the locking block 230 can limit the movement of the limiting section 322 along the length direction of the connecting section 321. When it is necessary to separate the first shell 100 and the second shell 300, it is only necessary to move the locking block 230 in the opposite direction to make it leave the locking position; by providing a receiving groove 3211 on one side of the connecting section 321, a space for accommodating the locking block 230 can be formed, which can not only make the locking block 230 lock the plug-in part 320, but also make the combination of the two compact and reduce the occupied space. Figure 4 In the illustrated embodiment, the connection section 321 and the limiting section 322 are connected to form an L-shape. When in the locking position, the locking block 230 is located in the L-shape to fix the second shell 300 .

[0046] Further, see Figure 1 and Figure 6 As shown, a positioning hole 130 is formed on the opening side of the first shell 100 facing the plug-in slot 110 , and the connecting mechanism 10 further includes a positioning pin 400 , which is connected to the second shell 300 and is used for plugging and mating with the positioning hole 130 .

[0047] With this arrangement, when the second shell 300 is connected to the first shell 100, the positioning pins 400 and the positioning holes 130 can be correspondingly plugged in to position the installation of the first shell 100 and the second shell 300; in a preferred embodiment, the number of the positioning pins 400 and the positioning holes 130 can both be multiple, and by providing multiple groups of positioning holes 130 in conjunction with the positioning pins 400, the installation accuracy between the first shell 100 and the second shell 300 can be improved.

[0048] Furthermore, the connection mechanism 10 also includes a reinforcing plate 500, which is arranged on a side of the second shell 300 away from the first shell 100, the positioning pin 400 is passed through the reinforcing plate 500, and the reinforcing plate 500 and the positioning pin 400 are connected to the second shell 300 through fasteners.

[0049] In this embodiment, the reinforcing plate 500 can be made of a material such as stainless steel or a material with a harderness greater than that of the second shell 300. By arranging the reinforcing plate 500 on the side of the second shell 300 away from the first shell 100, not only the overall strength of the second shell 300 can be improved, but also the connection strength between the positioning pin 400 and the second shell 300 can be improved. The structure is simple and easy to disassemble and assemble. Specifically, the fasteners include but are not limited to screws and pins.

[0050] In a preferred embodiment, there are multiple sets of locking devices 200, and the multiple sets of locking devices 200 are respectively connected to the first shell 100. When in the locked position, the multiple sets of locking devices 200 are respectively fixedly connected to the second shell 300.

[0051] like Figure 1 , Figure 4 and Figure 6 In the illustrated embodiment, there are two sets of locking devices 200, and the two sets of locking devices 200 are respectively arranged on opposite sides of the first housing 100. When the first housing 100 and the second housing 300 need to be separated, the lock on the second housing 300 can be released by adjusting the two sets of locking devices 200 to the release position; at the same time, the connection strength between the first housing 100 and the second housing 300 can be improved by providing two sets of locking devices 200. Of course, in some embodiments, the number of locking devices 200 can also be three or more sets. By providing multiple sets of locking devices 200 to connect the first housing 100 and the second housing 300, the connection strength between the two can be effectively improved.

[0052] The utility model also provides a medical installation device, which includes multiple plug-in boxes 1 and a connection interface 20; the multiple plug-in boxes 1 are provided with a connection mechanism 10 in any one of the above-mentioned embodiments, and the multiple plug-in boxes 1 are plugged in and matched with each other through the connection mechanism 10; the connection interface 20 is provided on the plug-in box 1, and the connection interfaces 20 between the two connected plug-in boxes 1 are connected to each other.

[0053] It can be understood that in the medical installation device of this embodiment, by setting the connection mechanism 10 in any of the above embodiments, the connection mechanism 10 of this embodiment cooperates with the first shell 100 and the second shell 300 respectively by setting the locking device 200, so that the first shell 100 and the second shell 300 can be quickly disassembled and assembled. When the connection mechanism 10 is used in the plug-in box, multiple plug-in boxes 1 can be conveniently disassembled and assembled, with a simple structure and good use effect. Specifically, the medical installation device can be applied to medical equipment such as infusion pumps.

[0054] Specifically, the connection interface 20 includes a data interface and / or a power interface; the connection interface 20 includes a female interface and a male interface, the female interface is arranged on the first shell 100, and the male interface is arranged on the second shell 300. When the two plug-in boxes 1 are connected, the female interface is connected to the male interface.

[0055] With this arrangement, the data interface can be used to transmit data signals between the two connected plug-in boxes 1, and the power interface can be used to supply power between the two connected plug-in boxes 1, and then the external device can be operated through the plug-in box 1, such as powering and automatically controlling the infusion pump. By respectively providing a female interface and a male interface on the first shell 100 and the second shell 300, when the two plug-in boxes 1 are connected to each other, the first shell 100 of one plug-in box 1 is correspondingly connected to the second shell 300 of the other plug-in box 1, so that the connection of the connection interface 20 can be realized, and the assembly and disassembly is convenient.
