DETAILED DESCRIPTION

[0045] With reference to the drawings and briefly describing the technical schemes in the embodiments of the present application, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0046] Before introducing the connecting structure of the present application, the structure of the existing medical trolley is introduced. The existing medical trolley generally comprises a support frame and a plurality of layer plates, and the plurality of layer plates are fixed on the support frame in sequence. In addition, most of the existing medical trolleys are provided with a shell. In some prior art, the shell also comprises a tail door or a rear cover designed at the rear of the medical trolley, which is also used to shield the cables connected with the medical trolley and related equipment. First, the existing installation method of the shell and the medical trolley is operated by at least two installers. First, one installer needs to lift the shell and align it to the installation position of the support frame and keep the hand force, so that the screw holes of the two are aligned, and then another installer uses the screw to fix the medical trolley and the shell. This way of operation is not convenient, and it needs to be operated by multiple people, which wastes labor cost. Secondly, the screw is exposed on the surface of the shell by penetrating the shell and the support frame from the outside of the shell, which affects the appearance of the medical trolley. Thirdly, in the general installation method, the two sides of the shell are fixed with the layer plates, and usually a connecting piece needs to be added on the side wall of the layer plate during fixing, which leads to the inconvenience of layer plate processing, the complication of layer plate processing procedure, and in the actual use process, if the rear cover is deformed by external force, the force will be directly transmitted to the layer plate, causing the chain deformation of the layer plate, and further affecting the stability of the medical equipment arranged on the layer plate. In addition, the fixing method of the layer plate is generally to use the screw to penetrate the support frame from the outside of the support frame and then extend into the side of the layer plate. However, the layer plate is usually thin, and if the screw is directly fixed on the side of the layer plate, the stability is poor, which is easy to cause the deformation of the layer plate.

[0047] In view of the problems existing in the structure of the above-mentioned existing medical trolley, please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , wherein Figure 2 (a) is a structure section view schematic diagram of the support frame 10 and the shell 20 after assembly, and (b) is a structure section view schematic diagram of the support frame 10 and the shell 20 before assembly. One embodiment of the present application provides a medical trolley, which comprises:

[0048] a base 50, wherein the base 50 is provided with the support frame 10;

[0049] at least one layer plate 60, wherein the layer plate 60 is connected with one side of the support frame 10;

[0050] The shell 20 is provided with a buckle portion 200 at the end in the direction of assembly with the support frame 10;

[0051] The support frame 10 is provided with a buckle groove 100, and the buckle portion 200 can extend into the buckle groove 100 in the direction of assembly of the shell 20, so as to connect the shell 20 with the support frame 10.

[0052] In the embodiment, the base 50 is used to mount the support frame 10, and the corresponding medical equipment or tool can also be placed on the base 50 according to the use requirement.

[0053] In the embodiment, the number of the layer plates 60 can be set according to the actual requirement, and the layer plates 60 are also used to place or mount the corresponding medical equipment. In an example of the embodiment, the layer plate 60 is a table board.

[0054] In the embodiment, the support frame 10 is mounted in cooperation with the shell 20. Since the buckle groove 100 is arranged on the inner side of the support frame 10, and the buckle portion 200 is arranged on the end of the shell 20 corresponding to the direction of assembly of the support frame 10 (the direction of assembly is shown as the X direction in the figure), when mounted, the preliminary connection and fixation between the support frame 10 and the shell 20 can be completed through the cooperation of the buckle portion 200 and the buckle groove 100, the shell 20 is prevented from falling, and the subsequent installation of the screw is facilitated. Figure 2

[0055] In the embodiment, since the buckle portion 200 is connected with the buckle groove 100, the shell 20 can be fixed on the support frame 10. When operated, the installer only needs to align the shell 20 with the support frame 10, and then install the shell 20 by clamping the buckle portion 200 into the buckle groove 100. The installer can release the hand after the installation is completed, and does not need to keep the hand force to install the screw. Then, the screw can be installed according to the actual requirement for reinforcement.

[0056] In the embodiment, the interior of the shell 20 is reserved with a large amount of wiring space, which facilitates the design of the wiring structure, maximizes the hiding of the wiring, solves the problem of the limitation of the internal space of the shell 20, increases the capacity of the wire harness, and facilitates the arrangement of the wire harness, so that the wiring is clear and obvious.

[0057] In an embodiment, please refer to Figure 2 , Figure 3 and Figure 4 , the medical trolley includes two support frames 10, the two support frames 10 are symmetrically arranged on the two sides of the layer plate 60, and the buckle groove 100 is arranged on the side of each support frame 10 close to the layer plate 60;

[0058] ​The shell 20 comprises a cover 21 and a bent portion 22, the bent portion 22 is symmetrically arranged on the left and right sides of the cover 21, and the buckle portion 200 is arranged at one end of the bent portion 22 away from the cover 21;

[0059] The buckle portion 200 is buckled with the buckle slot 100 through the elastic force of the bent portion 22, so that the shell 20 is connected and fixed with the support frame 10.

[0060] In the embodiment, firstly, the arrangement position of the buckle slot 100 in the support frame 10 and the structure of the shell 20 are further optimized. Specifically, the buckle slot 100 is arranged on the side of the two support frames 10 close to the layer plate 60, that is, the buckle slot 100 is located on the inner side of the support frame 10. Since the buckle slot 100 is arranged on the inner side of the support frame 10, during installation, the buckle portion 200 will also be located on the inner side of the support frame 10. At this time, if a screw needs to be added, the screw can be arranged from the inner side of the support frame 10, and the screw is inserted into the support frame 10 through the buckle portion 200 located on the inner side. When viewed from the outside, the support frame 10 or the shell 20 on the outside can not show the traces of screw installation, thereby improving the appearance of the medical trolley.

[0061] Secondly, in the embodiment, since the shell 20 comprises the cover 21 and the bent portion 22. The bent portion 22 is made by bending the two sides of the shell 20 during processing. Therefore, the bent portion 22 has a certain elasticity, that is, as shown in Figure 1 , the bent portion 22 has a tendency to open in the direction of assembly, and since the buckle slot 100 is located on the inner side of the support frame 10 and the buckle portion 200 is located at one end of the bent portion 22, after installation, the two symmetrical bent portions 22 will respectively fit on the inner sides of the two symmetrical support frames 10. At this time, through the elastic force of the bent portion 22, the connection between the shell 20 and the support frame 10 can be further reinforced, and the stability of the installation is improved.

[0062] In one embodiment, please refer to Figure 3 , a plurality of buckle portions 200 are respectively arranged on the left and right sides of the cover 21, and the layer plate 60 is connected with the support frame 10 between the adjacent two buckle portions 200.

[0063] In the embodiment, the plurality of buckle portions 200 are arranged at intervals, and the purpose is not to affect the installation of the layer plate. That is, during installation, the buckle portion 200 is buckled with the buckle slot 100 on the corresponding position of the support frame 10, and the layer plate 60 can also be installed and fixed with the support frame 10 at the position between the two buckle portions 200 without obstacles, so that the two do not interfere with each other during installation, and the convenience of installation is improved.

[0064] In one embodiment, please refer to Figure 1 , Figure 5 and Figure 6The buckle portion 200 comprises a first clamping portion 201, a second clamping portion 202 and a third clamping portion 203 connected in sequence, the first clamping portion 201 is connected with the bending portion 22, and the third clamping portion 203 extends into the buckle slot 100.

[0065] The first clamping portion 201 and the second clamping portion 202 form an assembly slot 204, the support frame 10 is provided with an assembly portion 101 on a side of the buckle slot 100 close to the assembly slot 204, and in a state that the shell 20 and the support frame 10 are assembled, the assembly portion 101 is fixed in the assembly slot 204.

[0066] In the embodiment, the structure of the buckle portion 200 is further described in detail. In a state that the shell 20 and the support frame 10 are assembled, the buckle portion 200 limits the shell 20 in an assembly direction (as indicated by an X direction in Figure 2 In a state that the shell 20 and the support frame 10 are assembled, the second clamping portion 202 limits the shell 20 in a direction perpendicular to the assembly direction (as indicated by a Y direction in Figure 2 In a state that the shell 20 and the support frame 10 are assembled, the buckle portion 200 extends the third clamping portion 203 into the assembly slot 204, at this time, the third clamping portion 203 extends into the assembly slot 204 to prevent the shell 20 from being separated from the support frame 10, meanwhile, the assembly portion 101 on the side of the support frame 10 close to the assembly slot 204 is fixed in the assembly slot 204 formed by the first clamping portion 201 and the second clamping portion 202, and finally the shell 20 and the support frame 10 are assembled and fixed.

[0067] In an embodiment, the buckle portion 200 is an integrally formed structure, that is, the first clamping portion 201, the second clamping portion 202 and the third clamping portion 203 are formed by mechanical bending or injection molding.

[0068] In an embodiment, please refer to Figure 6 The first clamping portion 201 is perpendicular to the second clamping portion 202, and an included angle between the third clamping portion 203 and the second clamping portion 202 is an obtuse angle.

[0069] In the embodiment, when the first clamping portion 201 is perpendicular to the second clamping portion 202, in the process of assembling the buckle portion 200 along the assembly direction, the assembly slot 204 formed by the first clamping portion 201 and the second clamping portion 202 can form effective pressure on the assembly portion 101 to stably clamp the assembly portion 101 in the assembly slot 204, and the third clamping portion 203 can be easily clamped into the buckle slot 100.

[0070] When the included angle between the first clamping portion 201 and the second clamping portion 202 is an acute angle, the clamping portion 200 needs additional force to expand the included angle or further swing the bent portion 22 away from the support frame 10 to avoid the interference of the assembling portion 101 when assembling along the assembling direction, and then the third clamping portion 203 is clamped into the clamping groove 100.

[0071] When the included angle between the first clamping portion 201 and the second clamping portion 202 is an obtuse angle, the third clamping portion 203 is difficult to be stably clamped into the clamping groove 100 when assembling along the assembling direction, and the first clamping portion 201 and the second clamping portion 202 are also difficult to effectively press the assembling portion 101.

[0072] When the included angle between the third clamping portion 203 and the second clamping portion 202 is an obtuse angle, the third clamping portion 203 can be easily clamped into the clamping groove 100 and form a corner with the notch of the clamping groove 100 to prevent the shell 20 from being detached along the reverse direction of the assembling direction when assembling along the assembling direction.

[0073] When the included angle between the third clamping portion 203 and the second clamping portion 202 is a right angle or an acute angle, the third clamping portion 203 will first contact the surface of the assembling portion 101 and be interfered by the assembling portion 101 when assembling along the assembling direction, and then additional force is needed to expand the included angle or further swing the bent portion 22 away from the support frame 10 to avoid the interference of the assembling portion 101, and then the third clamping portion 203 is clamped into the clamping groove 100.

[0074] In the embodiment, the third clamping portion 203 of the clamping portion 200 is a "flange structure" to achieve the effect of preventing the shell 20 from being detached.

[0075] In one embodiment, referring to Figure 6 , the surface of the assembling portion 101 facing the connection between the first clamping portion 201 and the second clamping portion 202 is an arc surface.

[0076] In the embodiment, the structure with the arc surface is provided in the assembling portion 101 before and after assembling, and the arc surface is located at the connection between the first clamping portion 201 and the second clamping portion 202 in the assembled state. The arc surface is provided to make the third clamping portion 203 and the second clamping portion 202 more smoothly move along the assembling direction during the assembling process, and ensure that the third clamping portion 203 can be easily clamped into the clamping groove 100.

[0077] In one embodiment, referring to Figure 1 , Figure 9 and Figure 10The medical trolley further comprises a first positioning member 30 arranged on the first clamping portion 201, and the side of the assembly portion 101 facing the first clamping portion 201 is provided with a positioning hole 102; the first positioning member 30 extends into the support frame through the positioning hole 102.

[0078] In the embodiment, after the shell 20 is snap-connected with the support frame 10, in order to further avoid the sliding between the shell 20 and the support frame 10, the first positioning member 30 is arranged, and the first positioning member 30 is used to realize the pre-positioning between the shell 20 and the support frame 10. During assembly, the snap portion 200 moves along the assembly direction, and the first positioning member 30 moves into the positioning hole 102 first, and then the first clamping portion 201 abuts against the assembly portion 101, so that the first positioning member 30 can prevent the shell 20 from sliding along the height direction of the support frame 10, and further prevent the shell 20 from sliding in the direction perpendicular to the assembly direction (for example, the Y direction shown in the figure). Figure 2

[0079] In one example, the first positioning member 30 is a positioning column, a positioning pin or a screw.

[0080] In one embodiment, please refer to Figure 1 , Figure 7 and Figure 8 , the second clamping portion 202 is provided with a first reinforcing hole 2021, and the support frame 10 is provided with a second reinforcing hole 103 corresponding to the first reinforcing hole 2021; the medical trolley further comprises a reinforcing member 40 arranged in the support frame 10 through the first reinforcing hole 2021 and the second reinforcing hole 103.

[0081] In the embodiment, first, since the snap groove 100 is arranged on the inner side of the support frame 10, the second clamping portion 202 is also located on the inner side of the support frame 10, and the reinforcing member 40 is arranged in the support frame 10 through the second clamping portion 202 of the shell 20 and the support frame 10, so that the reinforcing member 40 can be hidden in the interior of the shell 20, and is prevented from being exposed on the surface of the shell 20, thereby improving the appearance of the medical trolley. Secondly, while being prevented from being exposed, the reinforcing member 40 can further prevent the shell 20 from sliding along the height direction of the support frame 10, and further prevent the shell 20 from sliding in the assembly direction (for example, the x direction shown in the figure).

[0082] In one example, the reinforcing member 40 is a screw.

[0083] It should be noted that, in the embodiments of the present application, please refer to Figure 1 and the above-mentioned first positioning member 30 and reinforcing member 40 shown in the drawings, wherein the first positioning member 30 and the reinforcing member 40 are located on different horizontal planes, and the purpose is to avoid interference between the two during installation. ​

[0084] In one embodiment, the material of the shell 20 is metal. Metal has higher bending resilience than other materials such as plastic, which can ensure that the buckle part 200 is stably installed with the buckle groove 100. In one embodiment, the bent part 22 is a sheet metal bent part 22. The resilience of the sheet metal itself is used to make the bent part 22 an elastic wall, so that the shell 20 is firmly connected and fixed with the support frame 10, and pre-tightening between the shell 20 and the support frame 10 is achieved.

[0085] In one embodiment, please refer to Figure 11 and Figure 12 The side of the support frame 10 close to the layer plate 60 is provided with a plurality of second positioning members 70, and the plurality of second positioning members 70 are arranged at the same height. The bottom of the side of the layer plate 60 close to the support frame 10 is provided with a fixed part 601, and the end of the fixed part 601 away from the layer plate 60 is provided with a plurality of positioning grooves 602. The plurality of positioning grooves 602 correspond to the plurality of second positioning members 70 one by one, and each positioning groove 602 is provided with an opening at the end away from the layer plate 60, so that the second positioning member 70 can be clamped into the positioning groove 602. The second positioning member 70 is used to cooperate with the positioning groove 602 of the fixed part 601 on the layer plate 60 to achieve the pre-positioning function of the layer plate 60 during installation. In this embodiment, at least two second positioning members 70 are included, so that the layer plate is pre-positioned more stably, thereby facilitating subsequent installation.

[0086] One end of the second positioning member 70 is fixed in the interior of the support frame 10, and the other end extends out of the side of the support frame 10 towards the side close to the layer plate 60. The positioning groove 602 is correspondingly arranged at the bottom of the side of the layer plate 60 close to the support frame 10 and opens in the direction away from the layer plate 60. In Figure 11 , it can be seen that it opens in the direction towards the bottom, i.e. towards the base 50. During installation, the layer plate is placed from above between the two support frames 10. During the placement process, the positioning groove 602 is aligned with the second positioning member 70, so that the second positioning member 70 is clamped into the positioning groove 602 along the opening, thereby achieving the pre-positioning of the layer plate 60. Then, the installation and fixing of the layer plate 60 and the support frame 10 are performed. This structure can effectively reduce the use of personnel, and a single person can complete the installation of the layer plate. At the same time, the opening of the positioning groove 602 in the direction away from the layer plate 60 also allows the layer plate 60 to be gently placed from above when the layer plate 60 is installed in the symmetrically arranged support frames 10, thereby achieving pre-fixing. If there is no opening, the layer plate 60 needs to be aligned and clamped from the side of the support frame 10, which is inconvenient to operate due to the obstruction of the symmetrically arranged support frames 10.

[0087] In one embodiment, please refer to Figure 11 and Figure 12The medical trolley further comprises at least one fixing member 80, one end of the fixing member 80 penetrating through the fixing portion 601 and the side of the support frame 10 close to the fixing portion 601 and being fixed in the support frame 10.

[0088] In the embodiment, the fixing member 80 is used to complete the mounting and fixing between the layer plate 60 and the support frame 10. Specifically, the mounting and fixing of the two are completed by fixing the fixing member 80 penetrating through the fixing portion 601 of the layer plate 60 into the support frame 10 at the inner side of the support frame 10. Similarly, since the fixing member 80 penetrates into the support frame 10 from the inner side, the fixing member 80 is also not exposed outside the shell 20 or the support frame 10.

[0089] In the embodiment, since the fixing member 80 is arranged far away from the first positioning member 30 and the reinforcing member 40, the fixing member 80 can be arranged on the same horizontal plane as the first positioning member 30 or the reinforcing member 40.

[0090] In one embodiment, the structure of the layer plate 60 is optimized, please refer to Figure 11 and Figure 12 The layer plate 60 comprises a top plate 603 and a bottom plate 604, the top plate 603 comprises a table plate 6031 and a side plate 6032, and the fixing portion 601 is arranged on the side plate 6032 close to the support frame 10.
