Description

Technical Field

[0001] This invention relates to concealed handles for server racks, specifically concealed handles applicable to server racks. Background Technology

[0002] Concealed cabinet handles refer to handles that are hidden and embedded within the cabinet panel. Some of these products feature a handle-less, flush-mounted recessed design, while others retract their handles into the cabinet when not in use, with the handle surface flush with the cabinet panel. To use, the handle is pulled out or pressed to pop it out. For example, Chinese patent application number 202323258344.6, authorized on July 5, 2024, entitled "A Concealed Cabinet Door Handle for Easy Use," is disclosed. However, the handles of these and similar products are mainly handles or levers, with one end hinged and fixed within the cabinet or base, popping out via a torsion spring or strut. This results in inconvenience in production, installation, and use, higher production costs, poor stability, and an overly simplistic structural design, making it difficult to promote in various application scenarios. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the purpose of this invention is to provide a concealed handle for server racks, thereby addressing the technical problems of existing similar products, such as inadequate structural design leading to inconvenience in production, installation, and use, high production costs, poor stability, overly simplistic structural forms, and limited applicability. This objective is achieved through the following technical solution.

[0004] A concealed handle for server racks includes a handle body, a self-locking structure, a swing arm mechanism, a spring structure, and a trigger-release mechanism. Key structural design features include: one end of the handle body is inserted into and confined within a fixed base; at least one spring structure is located at the bottom of the handle body within the fixed base to stably extend and retract the handle body from the rack panel; the handle body is embedded within the rack panel; a trigger-release mechanism is provided on one side of the handle body opening on the rack panel to limit the handle body's ejection; a self-locking structure is located on one side of the handle body within the fixed base; one end of the swing arm mechanism is fixed to the fixed base below the self-locking structure; the other end of the swing arm mechanism is movably connected to and confined within the self-locking structure of the handle body. The trigger-release mechanism can also be fixedly mounted on the fixed base at the end of the handle body extending from the rack panel, allowing for overall installation and removal via the concealed handle. The handle body is not limited to the following door frame-shaped structure design; it can also adopt an L-shaped or other shapes. Two or more springs, or a large spring, are set at the bottom of the handle body corresponding to the fixing base to ensure that the handle body can be stably ejected.

[0005] Based on the above structural features, the self-locking structure is provided with a height difference track. The end of the swing arm mechanism at the self-locking structure moves within the height difference track, and the height difference within the height difference track drives the self-locking and unlocking of the handle body.

[0006] The height difference track includes a high-position locking point and a low-position release point, with the high-position locking point being higher than the low-position release point. The high-position locking point and the low-position release point of the height difference track are located on one side of the handle body inside the fixed base, with the high-position locking point being the locked position and the low-position release point being the released position.

[0007] The other end of the swing arm mechanism within the fixed base is movably connected to and limited by a self-locking structure on the handle body via a shaped groove at the high locking point of the high-low difference track and a straight groove at the low release point below. The shaped groove at the high locking point is heart-shaped, with a raised heart-shaped boss in the middle of the annular track groove, the boss being lower than the opening of the groove. The end of the swing arm mechanism at the high locking point enters one side of the annular track groove along the straight groove and locks in the upper locking groove in the middle of the annular track groove. The handle body is locked by the trigger release mechanism, and the spring structure deforms. Pressing the trigger release mechanism causes the end of the swing arm mechanism at the locking groove to return to the straight groove along one side of the original annular track groove or the symmetrical other side of the annular track groove, and slide. The spring structure pushes the handle body out. The above is a specific structural embodiment of the high locking point and low release point of the high-low difference track in the self-locking structure.

[0008] The handle body is shaped like a door frame with an opening on one side. A first spring and a second spring are respectively installed at both ends of the handle body within the fixed base. These springs form the spring structure. At least one side of the handle body within the fixed base has a corresponding swing arm mechanism for its self-locking structure. The swing arm mechanism is an elastic steel wire bent at both ends. One end of the elastic steel wire is inserted into the side groove of the fixed base below the low-position release point of the height difference track at the self-locking structure. The other end of the elastic steel wire is inserted into the height difference track at the self-locking structure on one side of the handle body above the side groove. Based on these structural features, the self-locking structure and the swing arm mechanism can also be symmetrically arranged at both ends of the handle body within the fixed base as needed.

[0009] One end of the first spring and the second spring are respectively inserted into the first spring post and the second spring post at both ends of the handle body inside the fixed base. The other ends of the first spring and the second spring abut against the spring grooves inside the fixed base. The two ends of the handle body inside the fixed base are respectively limited to moving within the sliding grooves or sliding holes inside the fixed base by the first pin and the second pin driven in, and / or by the limiting edges of the outer diameter protrusions at both ends of the handle body inside the fixed base. The other ends of the first spring and the second spring abut against the spring grooves inside the fixed base, or are respectively inserted into the corresponding spring posts, thereby facilitating further fixation of the first spring and the second spring, and omitting the following fixing cover structure.

[0010] The handle body at both ends of the fixed base has protruding limiting blocks on its limiting edges. Each end of the handle body is limited by these limiting blocks to move within another groove or hole within the fixed base. These limiting blocks, in conjunction with other limiting edges, pins, and other structures, further ensure the stability of the handle body during use and extend its service life.

[0011] One side of the mounting base is provided with a mounting cover for encapsulating the internal components of the mounting base. The mounting cover has corresponding sliding grooves or sliding holes, and the mounting base is in the shape of a thin rectangular sheet with low thickness. Thus, the mounting cover facilitates the encapsulation of the corresponding components inside the mounting base, as well as the overall installation and removal of the concealed handle; at the same time, the thin sheet shape of the concealed handle helps to reduce its space occupation and facilitates installation and removal.

[0012] The spring structure connects the handle body to the fixed base. The handle body stores elastic energy through the spring structure, and pushes the handle body out of the cabinet panel after the handle body is unlocked.

[0013] The other end of the handle body is flush with the cabinet panel, or the handle body surface is slightly higher than the handle body hole of the cabinet panel.

[0014] The trigger release mechanism is a mechanical button or a sensor switch. The specific form of the trigger release mechanism can be set as needed, and existing structures such as buttons or push buttons can be used.

[0015] This invention features a reasonable structural design, ease of use, good stability, small space occupation, diverse structural forms, and a wide range of applications; it is suitable for use as a concealed handle in server racks, as well as for structural improvements to similar products.

[0024] The structure and use of this invention will now be further described with reference to the accompanying drawings. This concealed handle is applied in the field of server rack accessories technology, and is a concealed handle for server racks and its mechanical self-locking spring-opening structure. Figures 1-7 As shown, the concealed handle includes a handle body 5, a self-locking structure, a swing arm mechanism, a spring structure, and a trigger release mechanism 9. One end of the handle body is inserted into and confined within the fixed base 1. The bottom of the handle body within the fixed base is provided with at least one spring structure that stably extends and retracts the handle body from the cabinet panel. The handle body is embedded in the cabinet panel. On one side of the handle body opening on the cabinet panel, the cabinet or fixed base is provided with a trigger release mechanism that limits the extension of the handle body. A self-locking structure is provided on one side of the handle body within the fixed base. One end of the swing arm mechanism within the fixed base is fixed to the fixed base below the self-locking structure, and the other end of the swing arm mechanism within the fixed base is movably connected to and confined within the self-locking structure of the handle body. The aforementioned self-locking structure is provided with a height difference track 503. The end of the swing arm mechanism in the self-locking structure moves within the height difference track, and the height difference within the height difference track drives the self-locking and unlocking of the handle body. The height difference track includes a high-position locking point 5031 and a low-position releasing point 5032, with the high-position locking point being higher than the low-position releasing point. The high-position locking point and the low-position releasing point of the height difference track are located on one side of the handle body within the fixed base, with the high-position locking point being the locking position and the low-position releasing point being the releasing position.

[0025] The other end of the swing arm mechanism inside the aforementioned fixed base is movably connected to and limited by the self-locking structure of the handle body through the irregular groove at the high locking point of the high-low difference track and the straight groove at the low release point below. The irregular groove at the high locking point is heart-shaped, and a heart-shaped boss is provided in the middle of the annular track groove of the heart shape. The heart-shaped boss is lower than the groove opening of the irregular groove. After the end of the swing arm mechanism inside the high locking point enters one side of the annular track groove of the heart shape along the straight groove, it locks in the upper locking groove in the middle of the annular track groove of the heart shape. The handle body is locked by the trigger release mechanism, and the spring structure deforms. When the trigger release mechanism is pressed, the end of the swing arm mechanism at the locking groove returns to the straight groove along one side of the original annular track groove of the heart shape or the other side of the annular track groove of the heart shape and slides. The spring structure pushes the handle body to pop out.

[0026] The aforementioned spring structure connects the handle body to the mounting base. The handle body stores elastic energy through the spring structure, which pushes the handle body out of the cabinet panel after the handle body is unlocked. The other end of the handle body is flush with the cabinet panel, or the surface of the handle body is slightly higher than the handle body hole on the cabinet panel. The trigger release mechanism is a mechanical button or a sensor switch.

[0027] The aforementioned concealed handle has its handle body embedded in the cabinet panel, with the surface of the handle body flush with the cabinet panel. The self-locking structure has a height difference track for locking and unlocking the handle body. One end of the swing arm mechanism is connected to the handle body, and the other end moves within the self-locking structure, achieving self-locking and unlocking through the height difference within the height difference track. A spring structure is set between the handle body and the fixed base for storing and releasing elastic energy. A trigger release mechanism is used to trigger the self-locking structure to unlock, causing the handle body to spring open under the action of the spring.

[0028] When the handle is closed, the handle body is flush with the cabinet panel, and the lever mechanism is at the high locking point of the self-locking structure. Simultaneously, the handle body is mechanically locked by the trigger release mechanism. When the user presses the trigger release mechanism, the lever mechanism moves along the height difference track to the low release point, the spring releases its stored energy, and the handle body pops out. After use, pressing the handle body returns the lever mechanism to the high locking point along the height difference track, the spring re-stores energy, and the self-locking mechanism is restored.

[0029] The specific structural design of its embodiment is as follows: The handle body is a door frame shape with an opening on one side. The two ends of the handle body in the fixed seat are respectively provided with a first spring 3 and a second spring 8. The first spring and the second spring serve as the spring structure. At least one side of the self-locking structure in the fixed seat is provided with a corresponding swing rod mechanism. The swing rod mechanism is an elastic steel wire 7 with both ends bent. One end of the elastic steel wire is inserted into the side ear groove 101 of the fixed seat below the low release point of the height difference track at the self-locking structure. The other end of the elastic steel wire is inserted into the height difference track at the self-locking structure on one side of the handle body above the side ear groove. One end of the first spring and the second spring are respectively inserted into the first spring post 501 and the second spring post 502 at both ends of the handle body inside the fixed base. The other ends of the first spring and the second spring abut against the spring grooves inside the fixed base. The two ends of the handle body inside the fixed base are limited to moving within the sliding grooves or sliding holes inside the fixed base by the first pin 4 and the second pin 6 driven in. The two ends of the handle body inside the fixed base are provided with protruding limiting blocks 505 at the limiting edges, and the two ends of the handle body inside the fixed base are limited to moving within another sliding groove or sliding hole inside the fixed base by the limiting blocks. A fixing cover 2 for encapsulating the internal components of the fixed base is provided on one side of the fixed base, and the fixing cover is provided with corresponding sliding grooves or sliding holes.

[0030] When locking, pressing down on the handle body causes one end of the elastic steel wire to slide from the lower release point to the higher locking point within the height difference track of the self-locking structure on one side of the handle body inside the fixed base, until the handle body retracts into the cabinet panel. At this point, the elastic steel wire engages with the locking groove of the higher locking point, triggering the release mechanism (button) to lock the handle body. The first and second springs deform. When unlocking, pressing the release mechanism disengages the handle body from the mechanism. The first and second springs reset, pushing the handle body out of the cabinet panel. One end of the elastic steel wire within the height difference track of the self-locking structure returns from the higher locking point to the lower release point, until the handle body is limited within the fixed base by the corresponding limiting edge, limiting block, and pin. At this point, the handle body can be pulled.

[0031] The above description is intended to illustrate the technical means of the present invention and is not intended to limit the technical scope of the present invention. Any obvious improvements or substitutions made to the present invention by those skilled in the art based on existing common knowledge also fall within the protection scope of the claims of the present invention. For example, the aforementioned trigger release mechanism may be disposed on one side of the fixed base as needed, extending out of the handle body hole of the cabinet panel, and the end of the handle body corresponding to the trigger release mechanism may have a notch for locking.
