Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, and in particular to a modular sheet metal handle strip for large cabinets. Background Technology

[0002] In existing large server racks and chassis structures, there are handles mounted on one side of the door or the side of the rack panel. These handles are mainly used for opening the door or for dragging. Traditionally, for handles of such large equipment, a post-assembly method is mainly adopted, that is, the rack body is assembled first, and then the handles are welded on.

[0003] Unlike handles for small equipment, the assembly process for handles and cabinets of large equipment is currently too complicated. It requires the individual welding and assembly of multiple panels and handle bodies to ensure strength. The number of welding points is large, and the whole process is time-consuming and labor-intensive.

[0004] In view of this, this technical solution proposes a modular sheet metal handle strip for large cabinets. It adopts a modular two-section sheet metal assembly structure. The entire handle mechanism is assembled with screws without welding. The sheet metal is formed by one-piece stamping. It is not only stronger than traditional handle strips, but also greatly improves the efficiency of assembly, maintenance or modification. Utility Model Content

[0005] The present invention aims to at least partially solve one of the technical problems in the related art. Therefore, the main objective of this invention is to provide a modular sheet metal handle strip for large cabinets, aiming to solve the problems of complex assembly and low assembly efficiency of handle strips used in large equipment in the prior art.

[0006] To achieve the above objectives, this utility model provides a modular sheet metal handle strip for large server racks, comprising a handle strip body consisting of a connecting middle frame, connecting side frames, and a handle. The connecting frame includes a frame body and a connector disposed at the end of the frame body. The frame body is a vertical frame enclosed on three sides, and one side of the connector protrudes to form a first side connecting plate. The connecting side frame is located behind the main body of the middle frame and is parallel to the main body of the middle frame. The middle of the connecting side frame has a flat strip structure, and one end of the connecting side frame has a second connecting plate that is fitted to the first side connecting plate. The top of the second side connecting plate is bent vertically to one side, framing the gap between the second side connecting plate and the connector. A latch is provided on one side of the top of the connecting side frame. The pivot of the latch passes through the connector and connects to the hook at the top of the handle. The main body of the middle frame and the connecting side frame are both integrally stamped and bent metal plate structures, and the second side connecting plate is connected to the first side connecting plate by detachable fasteners.

[0007] As a further embodiment of this utility model, the top corner of the connector is recessed to form a placement recess, and the bottom of the hook is located on the placement recess.

[0008] As a further embodiment of this utility model, the top of the latch is provided with a limiting cover, and one side of the limiting cover is connected to the top of the connecting side frame.

[0009] As a further embodiment of this invention, the fastener is a screw with washers connected in series.

[0010] As a further embodiment of this utility model, the top of the second side connecting plate is bent vertically to one side to form a top cover, and the head of the top cover is connected to the inner wall of the connecting head.

[0011] As a further embodiment of this utility model, the main body of the middle frame and the connecting side frame are sequentially provided with assembly holes and hollow positions on the surface in the Z-axis direction.

[0012] The beneficial effects of this utility model are as follows: This technical solution designs the handle strip as a modular body consisting of a connecting middle frame, a connecting side frame, and a handle. The connecting middle frame and the connecting side frame are both made of one-piece stamped and bent metal sheet structure, and are connected by a first side connecting plate and a second side connecting plate with detachable fasteners. At the same time, the locking pin passes through the connector head and the hook of the handle to achieve the cooperation.

[0013] This solution completely overcomes the technical challenge of the complex process of welding each component individually for traditional handle strips, significantly improving assembly efficiency and facilitating subsequent maintenance or replacement. The one-piece molded sheet metal structure ensures overall strength, while the detachable connection effectively avoids welding deformation and stress concentration issues. This allows the handle strip to achieve quick and flexible assembly and maintenance while possessing high structural stability and durability, significantly improving the convenience and economy of using large cabinet handle strips.

[0022] Please see the appendix Figure 1-4 , The modular sheet metal handle strip for large cabinets in this technical solution consists of three main parts: a connecting middle frame (11), a connecting side frame (12), and a handle (10). The connecting middle frame (11) includes a middle frame body (110) and a connector (111) located at the end of the middle frame body (110). The middle frame body (110) is a vertical frame enclosed on three sides. One side of the connector (111) protrudes to form a first side connecting plate (112). The connecting side frame (12) is located on the rear side of the middle frame body (110) and is parallel to the middle frame body (110). The middle part of the connecting side frame (12) is a flat strip structure. One side of its end is provided with a second side connecting plate (13) that is fitted to the first side connecting plate (112). The top of the second side connecting plate (13) is bent vertically to one side to frame and cover the gap between the second side connecting plate (13) and the connector (111). A latch (120) is installed on one side of the top of the connecting side frame (12). The pivot (121) of the latch (120) passes through the connector (111) and is connected to the hook (100) at the top of the handle (10).

[0023] For example, in the actual assembly process, the main body of the middle frame (110) and the connecting side frame (12) are initially fixed by detachable fasteners (131). Then, the bottom of the latch (120) is assembled on the top of the connecting side frame (12). Next, the hook (100) of the handle (10) is connected to the pivot (121) of the latch (120). Then, the holes of the second side connecting plate (13) and the first side connecting plate (112) are aligned and locked by fasteners (131) (such as screws). Finally, the bent part at the top of the second side connecting plate (13) encapsulates and fixes the connector (111) and the top of the connecting side frame (12) to form an integral structure.

[0024] The beneficial effect is that this modular assembly method avoids the complicated process of traditional welding. The entire process can be completed simply by tightening screws, which significantly improves the assembly efficiency. At the same time, the main body of the middle frame (110) and the connecting side frame (12) are both made of one-piece stamped and bent metal plate structure, which is not only strong and durable, but also detachable and easy to maintain or modify later. This effectively solves the problem of cumbersome, time-consuming and labor-intensive assembly of handle strips for large equipment.

[0025] Reference Appendix Figure 3In a preferred embodiment of this utility model, a recessed placement recess (113) is formed by recessing one corner of the top side of the connector (111). The bottom of the hook (100) at the top of the handle (10) falls on this placement recess (113) after assembly. The connection between the hook (100) and the latch (120) can be stably accommodated in the recessed space. Unlike the traditional method of opening windows or drilling holes in the plate, the placement recess (113) is a positioning structure directly produced by stamping, which avoids assembly errors or component deformation that may be caused by hole tolerance.

[0026] Understandably, the bottom of the hook (100) is located in the recess, which not only provides accurate positioning and stable support, but also exposes the key connection parts of the top of the latch (120) and the hook (100) without any obstruction. This greatly facilitates the alignment operation during assembly and subsequent maintenance and repair. It allows for direct observation and touch without disassembling other parts, effectively improving the convenience and maintainability of assembly.

[0027] Reference Appendix Figure 4 In a preferred embodiment of this utility model, a limiting cover (122) is provided on the top of the latch (120). One side of the limiting cover (122) is connected to the top of the connecting side frame (12). Its main function is to cover the latch (120) from above and limit its position. This can effectively prevent the latch (120) from accidentally coming off upwards during operation or equipment vibration, ensuring the long-term reliability and stability of the connection between the latch (120) and the hook (100) on the handle (10). It also makes it easy and intuitive to maintain or inspect the latch (120).

[0028] Reference Appendix Figure 3 In a preferred embodiment of this utility model, the detachable fastener (131) used to connect the second side connecting plate (13) and the first side connecting plate (112) is a screw with a washer connected in series.

[0029] During actual assembly, the washer is fitted over the screw. When the screw is tightened to connect the two connecting plates, the washer fills any tiny gaps that may exist between the contact surfaces of the plates, compensating for manufacturing tolerances and making the connection tighter and more secure. The washer also acts as a buffer, reducing the impact of vibrations generated during equipment operation or handling on the connection point, preventing the screws from loosening due to vibration, thereby significantly improving the sealing, stability, and durability of the connection.

[0030] It is understood that the fastener (131) in this solution can also be other detachable connectors, such as bolts, nuts or clips.

[0031] Reference Appendix Figure 3In a preferred embodiment of this utility model, the top of the second side connecting plate (13) is bent vertically to one side to form a top cover (130), and the head of the top cover (130) is finally connected to the inner wall of the connector (111).

[0032] Its beneficial effect is that after the second side connecting plate (13) is laterally fixed to the first side connecting plate (112), the top cover (130) can further cover and connect to the connector (111) from above, thereby covering the joint between the connector (111) and the top of the connecting side frame (12). This not only enhances the structural strength and integrity of the entire connection point in the upward direction and effectively prevents the parts from deforming or loosening, but also plays a good shielding role, making the appearance neater.

[0033] Reference Appendix Figure 3 In a preferred embodiment of this utility model, the main body of the middle frame (110) and the connecting side frame (12) are sequentially provided with mounting holes and hollow positions on the surface in the Z-axis direction. When the handle strip is installed on a large cabinet, these mounting holes can be used to make it easy to be fastened to the internal structure of the cabinet, ensuring the firmness of the installation. The distributed hollow positions not only effectively reduce the overall weight of the entire handle strip and save materials, but more importantly, they provide additional space and convenience for the passage, fixing or heat dissipation of other functional components (such as cables, modules, etc.) inside the cabinet, enhancing the functionality and application flexibility of the handle strip.

[0034] The following points need to be explained: (1) The accompanying drawings of the embodiments of this disclosure only involve the structures involved in the embodiments of this disclosure. Other structures can be referred to the general design.

[0035] (2) Where there is no conflict, features of the same embodiment and different embodiments of this disclosure can be combined with each other.

[0036] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
