Abstract
Description
Technical Field
[0001] This utility model relates to the field of equipment housing technology, and in particular to an in vitro diagnostic equipment housing. Background Technology
[0002] Currently, in vitro diagnostic equipment is increasingly widely used in the medical field. As the outer shell of the equipment, its design and manufacturing greatly affect the equipment's performance and appearance quality.
[0003] Currently, many in vitro diagnostic devices are manufactured using injection molding. However, the mold design and manufacturing costs are high, and defects such as shrinkage, bubbles, and flow marks are prone to occur during the injection molding process. Another common method for manufacturing housings is through a combination of sheet metal parts and prototype components. This method is typically used for customized or small-batch production. However, the manufacturing cost of prototype components is high, and the assembly precision requirements for sheet metal parts and prototype components are high, which can easily lead to uneven seams. Utility Model Content
[0004] The main purpose of this invention is to provide a housing for an in vitro diagnostic device, which aims to reduce production costs, simplify the installation process, and enhance the strength of the housing.
[0005] To achieve the above objectives, this utility model proposes an in vitro diagnostic device housing, comprising:
[0006] The outer shell body is a square structure formed by bending, with open bottom and front and rear sides. The inner wall of the outer shell body is also provided with support members.
[0007] The frame includes a main column, a base plate, a front panel, and a rear panel. The main column is connected to two opposite sides of the base plate, and the front panel and the rear panel are respectively connected to the front and rear sides of the main column.
[0008] The bottom openings on both sides of the outer casing are recessed inward, and the frame is inserted into the outer casing.
[0009] In one possible implementation, the support includes a reinforcing rib and a spring clip. The reinforcing rib is vertically connected to the inner wall of the outer shell body. The spring clip and the reinforcing rib are integrally formed and located on the side of the reinforcing rib. When the frame is inserted into the outer shell body, the spring clip is interference-fitted with the inner side of the main column.
[0010] In one possible implementation, the spring clip includes a guide portion and an abutment portion, the guide portion being bent toward a direction away from the inner side of the main column, and the abutment portion being interference-fitted with the inner side of the main column.
[0011] In one possible implementation, the ends of both sides of the outer shell body are bent inward to form two downward-curved edges.
[0012] In one possible implementation, the lower flange covers and adheres to the base plate, and threaded holes are provided at corresponding positions of the lower flange and the base plate for locking and fixing the lower flange and the base plate.
[0013] In one possible implementation, a crossbeam is provided between the two opposing main columns.
[0014] This utility model's technical solution involves installing the frame into the outer shell body via a plug-in connection. The open design and contraction structure of the outer shell body ensure a tighter fit between the shell and the frame, and the supporting components of the outer shell body enhance the overall structural stability. The frame is composed of components such as main columns, a base plate, a front panel, and a rear panel. The main columns, through cooperation with supporting components (such as spring clips and reinforcing ribs) on the inner wall of the shell, further enhance the connection strength between the shell and the frame. Moreover, the entire assembly method is simple, possesses good structural strength and aesthetics, and the sheet metal outer shell body has a lower cost, which helps reduce costs.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0026] To achieve the above objectives, in conjunction with reference Figures 1 to 6 As shown, the present invention provides an in vitro diagnostic device housing, comprising:
[0027] The outer shell body 10 is a square structure formed by bending, with open bottom and front and rear sides. The inner wall of the outer shell body 10 is also provided with a support member 20.
[0028] The frame 30 includes a main column 31, a base plate 32, a front panel 33, and a rear panel 34. The main column 31 is connected to two opposite sides of the base plate 32, and the front panel 33 and the rear panel 34 are respectively connected to the front and rear sides of the main column 31.
[0029] The bottom openings on both sides of the outer casing 10 are recessed inward, and the frame 30 is inserted into the outer casing 10.
[0030] In this embodiment, the outer casing 10 can be formed by bending sheet metal in one step, and its shape can be square or other shapes. The sheet metal bending process makes the cost of the outer casing 10 lower, and the casing has strong integrity and is easy to assemble. The bottom, front and rear sides of the outer casing 10 are designed with openings, that is, the bottom surface and front and rear sides of the outer casing 10 are not closed, leaving open areas for installing other components. The opening design at the bottom and sides facilitates the assembly of the frame 30 components into the inner casing 10, allowing the frame 30 to be easily inserted. The main columns 31 of the frame 30 are roughly square semi-frames installed on both sides of the base plate 32. Typically, two main columns 31 are located on the left and right sides of the frame 30 respectively, and are fixed to the base plate 32 by welding or other connection methods. The base plate 32 provides bottom support for the entire frame 30, and the main columns 31 are fixed on opposite sides of the base plate 32, thus forming the approximate frame of the frame 30 together with the base plate 32. The base plate 32 plays a crucial role in the assembly of the housing, supporting the main column 31 and the housing body 10, ensuring that the housing body 10 and the frame 30 can be stably installed and fixed together. The front panel 33 and rear panel 34 are respectively connected to the front and rear sides of the main column 31. The front and rear panels 34 not only enhance the stability of the main column 31 but may also serve as interface boards for mounting electrical components such as light panels and power sockets. The front and rear panels 34 can be connected to the main column 31 by screws or other fixing methods, providing additional structural stability. The main column 31, as the support column of the frame 30, provides the stability and structural strength of the housing. A support member 20 is installed on the inner wall of the housing body 10. The support member 20 can be welded and fixed to the inner wall of the housing body 10. The support member 20 is formed by bending sheet metal and typically includes reinforcing ribs 21 and spring clips 22. The support member 20 provides support within the housing body 10, enhancing the strength and stability of the housing body 10. Furthermore, the support member 20 and the spring clip 22 can closely cooperate with the main column 31 in the frame 30 to play a role in positioning and fixing, ensuring that the outer shell 10 and the frame 30 are stably connected.
[0031] It should be noted that the bottom sides of the outer casing 10 can be designed to taper inwards, which not only enhances the strength of the casing but also provides a certain degree of elasticity during installation. When the main column 31 of the frame 30 is inserted into the outer casing 10, the bottom sides of the casing, due to their taper design, can elastically adhere tightly to the base plate 32, which helps to make the casing and frame 30 more securely connected. The installation of the outer casing 10 and the frame 30 is completed by a plug-in method, that is, the opening area of the outer casing 10 is opposite to the main column 31 of the frame 30, and the frame 30 is inserted into the outer casing 10. The taper design on the bottom sides of the casing provides elasticity during installation, ensuring that the frame 30 is firmly secured within the outer casing 10 and preventing loosening. After assembly, the casing and frame 30 form a firm connection through the cooperation of the spring clips 22 and the reinforcing ribs 21.
[0032] In summary, the outer casing 10 and the frame 30 are installed into the outer casing 10 via a plug-in connection. The open design and contraction structure of the outer casing 10 ensure a tighter fit between the casing and the frame 30, and the support members 20 of the outer casing 10 enhance the overall structural stability. The frame 30 is composed of components such as the main column 31, the base plate 32, the front panel 33, and the rear panel 34. The main column 31, through its cooperation with the support members 20 (such as spring clips 22 and reinforcing ribs 21) on the inner wall of the casing, further enhances the connection strength between the casing and the frame 30. Moreover, the entire assembly method is simple, has good structural strength and aesthetics, and the sheet metal outer casing 10 has a lower cost, which helps to reduce costs.
[0033] Combined with reference Figure 1 and Figure 5 As shown, in one possible implementation, the support member 20 includes a reinforcing rib 21 and a spring clip 22. The reinforcing rib 21 is vertically connected to the inner wall of the outer shell body 10. The spring clip 22 and the reinforcing rib 21 are integrally formed and located on the side of the reinforcing rib 21. When the frame 30 is inserted into the outer shell body 10, the spring clip 22 is interference-fitted with the inner side of the main column 31.
[0034] In this embodiment, the support member 20 is part of the inner wall of the outer shell 10. Its function is to enhance the strength and stability of the outer shell and to facilitate a fixed connection with the main column 31 in the frame 30. The support member 20 consists of reinforcing ribs 21 and spring clips 22, both of which work together to enhance structural strength and provide stable support. The reinforcing rib 21 is a vertically positioned reinforcing component, typically a strip-shaped metal piece, positioned along the height of the outer shell. The vertical positioning of the reinforcing rib 21 ensures the strength of the outer shell, enabling it to maintain structural stability under external pressure or deformation. The reinforcing rib 21 is connected to the inner wall of the outer shell 10 by welding or other fixing methods to ensure its robustness. The spring clips 22 and the reinforcing ribs 21 can be integrally formed, allowing for one-time molding during sheet metal bending or stamping processes. The spring clip 22 is an elastic accessory, which can be V-shaped or other compressible shapes, and can be tightly engaged with the inner side of the main column 31 through an interference fit. The spring clip 22 is interference-fitted with the inner side of the main column 31, meaning that the V-shaped bottom of the spring clip 22 will form a certain compression fit with the inner side of the main column 31. Due to the elasticity of the spring clip 22, it will generate a certain pressure during assembly, so that the shell and the main column 31 can be tightly connected to prevent loosening. Through its elasticity, when the shell and the frame 30 are inserted, the spring clip 22 will compress inward and then return to its original shape when it contacts the inner side of the main column 31, thereby forming a strong locking force to ensure that the shell is firmly connected to the main column 31. When the frame 30 (including the main column 31, base plate 32, front panel 33 and rear panel 34, etc.) is inserted into the shell body 10, the spring clip 22 will slide along the inner side of the main column 31 until the spring clip 22 contacts the inner side of the main column 31 and is firmly locked into the main column 31 through the interference fit.
[0035] Combined with reference Figure 5 As shown, in one possible implementation, the spring clip 22 includes a guide portion 221 and an abutment portion 222. The guide portion 221 is bent toward the direction away from the inner side of the main column 31, and the abutment portion 222 is interference-fitted with the inner side of the main column 31.
[0036] In this embodiment, the guide portion 221 assists in correctly guiding and positioning the snap-fit 22, ensuring smooth installation when it mates with the main post 31. The guide portion 221 bends away from the inner side of the main post 31. Specifically, during assembly, the guide portion 221 ensures that the snap-fit 22 will not jam against the main post 31 upon insertion, but will slide smoothly along the inner side of the main post 31 until it reaches the final engagement position. Through this bending structure, the guide portion 221 ensures that the V-shaped bottom of the snap-fit 22 can slide smoothly along the inner side of the main post 31 and finally precisely align with the inner side of the main post 31, thereby avoiding misalignment or frictional resistance during assembly. The abutment portion 222 is located at the V-shaped bottom of the snap-fit 22. When it contacts the inner side of the main post 31, a secure engagement is achieved through an interference fit (i.e., the size of the snap-fit 22 is slightly larger than the contact surface of the main post 31). The elasticity of the spring clip 22 allows it to apply pressure to the main column 31, ensuring a tight fit between the housing and the main column 31 and preventing loosening. When the frame 30 is inserted into the housing, the guide portion 221 of the spring clip 22 first guides the spring clip 22 to slide along the inner side of the main column 31. Because the guide portion 221 bends away from the inner side of the main column 31, it ensures that the spring clip 22 does not deviate from its predetermined path. As the housing is pushed into the frame 30, the bending design of the guide portion 221 ensures that the spring clip 22 can slide smoothly along the inner side of the main column 31, and finally, the abutment portion 222 makes tight contact with the inner side of the main column 31 and locks the main column 31 in place through an interference fit. Through its elastic properties, the spring clip 22 applies pressure to the inner side of the main column 31 during the interference fit process, making the connection between the main column 31 and the spring clip 22 more secure, thereby ensuring the stability of the housing and the frame 30.
[0037] Combined with reference Figure 1 As shown, in one possible implementation, the ends of both sides of the outer shell body 10 are bent inward to form two downward flanges 11.
[0038] In this embodiment, the ends of both sides of the outer casing 10 (i.e., the outermost edges of the left and right sides of the outer casing 10) are folded inward to form lower flanges 11. The lower flanges 11 increase the strength of the outer casing 10, preventing deformation or bending of the outer casing during assembly or use, and also provide support for the connection between the outer casing and the base plate 32. These two lower flanges 11 are located symmetrically at the bottom ends of both sides of the outer casing 10, on the left and right sides respectively. The lower flanges 11 are formed by folding the outermost edges of both sides of the outer casing inward, creating an "L"-shaped structure. The lower flanges 11 ensure a tighter contact between the bottom edge of the outer casing and the base plate 32, increasing the overall stability of the outer casing.
[0039] By incorporating the downward-curved edge 11, the compressive strength and deformation resistance of the housing are effectively enhanced. Under external force, the side edges of the housing will not easily bend or deform, thus improving the overall structural stability of the housing. The downward-curved edge 11 also provides a better contact area for housing installation, especially for the connection with the base plate 32. The downward-curved edge 11 can mate with corresponding parts of the base plate 32, and can be firmly connected to the base plate 32 using screws or other fixing methods, ensuring a more stable connection between the housing and the base plate 32. It also reduces the exposed portion of the side edges of the housing, preventing the edges from appearing rough or unsightly. The downward-curved edge 11 makes the side treatment of the housing smoother and cleaner, while also avoiding potential safety hazards to users or equipment caused by sharp edges.
[0040] In one possible implementation, the lower flange 11 covers and fits the base plate 32, and threaded holes are provided at corresponding positions of the lower flange 11 and the base plate 32 for locking and fixing the lower flange 11 and the base plate 32.
[0041] In this embodiment, after bending, the lower flange 11 covers the edge of the base plate 32, forming a tight fit with the base plate 32. This ensures that there are no obvious gaps between the lower flange 11 and the base plate 32, allowing the two sides of the outer shell to evenly contact the base plate 32, forming a tight and stable connection. Threaded holes are provided at corresponding positions on the lower flange 11 and the base plate 32. These holes are used to install screws to fix the connection between the lower flange 11 and the base plate 32. The threaded holes allow the screws to firmly lock the lower flange 11 and the base plate 32, thereby enhancing the connection strength between the outer shell and the base plate 32. Through the threaded holes, the screws can be accurately tightened during installation, ensuring a stable connection between the two and preventing loosening due to vibration or external force. In addition, the threaded holes make the connection between the lower flange 11 and the base plate 32 more precise, reducing the likelihood of errors during installation and ensuring correct alignment and fixation.
[0042] Combined with reference Figure 2 As shown, in one possible implementation, a crossbeam 35 is provided between the two opposing main columns 31.
[0043] In this embodiment, the crossbeam 35 connects the two main columns 31 together, forming a more stable support frame. Because the crossbeam 35 acts as a connector, it effectively prevents relative displacement of the main columns 31 under external forces, thereby improving the overall stability and rigidity of the frame 30. The addition of the crossbeam 35 effectively prevents bending or deformation of the frame 30 structure. Especially under external pressure or vibration, the crossbeam 35 can distribute the force to the main columns 31 on both sides, thereby improving the load-bearing capacity of the entire frame 30. Through the connection of the crossbeams 35 between the main columns 31, the stability and load-bearing capacity of the entire frame 30 are greatly improved, effectively supporting the outer shell and preventing deformation of the frame 30 during use.
