Description

Technical Field

[0001] This invention relates to the field of equipment installation tools, and more specifically to a cabinet auxiliary installation support arm. Background Technology

[0002] Servers, switches, power modules, and other rack-mounted equipment are typically secured to the rack uprights via mounting lugs on the front or sides of the equipment. For larger or higher-mounted devices, installers often need to support the device while aligning it with the mounting holes and inserting the screws. This is difficult for a single person, and requiring two people to work together increases manpower requirements.

[0003] One type of existing temporary support arm can be inserted into the cabinet column to provide short-term support for the equipment. However, some structures use staggered components at the transition point between the support arm and the mounting end, fixed by a pin. This concentrates the stress, and if the pin is bent or deformed, it is inconvenient to replace it individually, potentially rendering the entire support arm unusable. Other structures rely solely on a single-point insertion, which makes them prone to vertical swaying, twisting, or shifting relative to the column after installation.

[0004] Furthermore, long, integral support arms are inconvenient to store and carry. If the connection strength between the mounting end and the main arm is insufficient, deformation or misalignment may occur at the connection point when supporting equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a cabinet auxiliary installation support arm to solve the problems of existing temporary support structures being prone to shaking or shifting, inconvenient maintenance after damage to the transition position, and inconvenient storage of the overall structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cabinet auxiliary installation support arm, comprising a support arm body, a hinge assembly, and two installation locking assemblies. The support arm body includes a first grooved half-arm and a second grooved half-arm, the relative inner ends of the two grooved half-arms being detachably hinged by the hinge assembly, and the two installation locking assemblies being respectively disposed at the opposite outer ends of the two grooved half-arms, so that the unfolded support arm can be connected between two spaced cabinet uprights.

[0007] Both the first and second slotted half-arms include a supporting base wall and side flanges that curve upwards from both sides of the supporting base wall. Each slotted half-arm has a hinge connection hole at its inner end near the hinge assembly, and an end limiting portion formed by a partial bend of the supporting base wall and / or the side flanges at its outer end away from the hinge assembly. The side flanges improve the bending stiffness of the slotted half-arm and provide lateral restraint to the supported equipment; the end limiting portion restricts the movement of the corresponding mounting locking assembly or the equipment to be installed along the length of the support arm.

[0008] Furthermore, each mounting locking assembly includes a mounting base, an edge limiting portion, and a spring positioning pin. The mounting base may include a first clamping piece and a second clamping piece spaced apart, forming a clamping space between them for at least a portion of the edge area of ​​the cabinet column to enter. The edge limiting portion is disposed within the clamping space and abuts against or engages with the edge of the column. The edge limiting portion may be a short limiting piece, a limiting block, or a bent portion located between the two clamping pieces.

[0009] Furthermore, the spring positioning pin includes a pin body, an operating head, and a return spring. When the operating head is pulled, the pin body exits the mounting hole of the cabinet column; after the operating head is released, the return spring drives the pin body to automatically return to the mounting hole. The edge limiting part and the spring positioning pin form positioning points spaced apart from each other, thereby limiting the up-and-down swaying, twisting, or offset of the support arm relative to the cabinet column.

[0010] Furthermore, each mounting base is secured to the outer end of the corresponding slotted half-arm by three mounting fasteners arranged in a triangular or triangular pattern. Compared to connection points arranged along a single straight line, the three-point distribution helps improve the torsional resistance of the mounting base and reduces the possibility of misalignment or deformation of the mounting base relative to the slotted half-arm under supporting loads.

[0011] Furthermore, the hinge assembly includes a first hinge piece, a second hinge piece, and a pivot portion, which are detachably fixed to the first and second slotted half arms, respectively. Hinge fasteners pass through corresponding hinge connection holes. The hinge assembly allows the two slotted half arms to be folded and stored; when the hinge assembly or any slotted half arm is damaged, the corresponding hinge fastener can be removed and replaced.

[0012] Furthermore, the first and second grooved half-arms extend along the same straight line in the unfolded position, with their supporting bottom walls flush or substantially flush to form a continuous supporting structure; in the folded position, the two grooved half-arms are adjacent and approximately parallel to shorten the storage length of the support arm. The supporting bottom wall can be provided with multiple weight-reducing holes, at least some of which are combined to form a flower-shaped hole group to balance support strength, ventilation, and portability.

[0013] The beneficial effects of this invention are as follows: the edge limiting part and the spring positioning pin work together to form a stable locking position, reducing up and down shaking, twisting and offset; the side flanges on both sides of the slotted half arm improve bending resistance; the triangularly distributed mounting fasteners improve the connection stability at both ends; the detachable hinge assembly allows the support arm to be folded and allows for the replacement and maintenance of the hinge assembly, slotted half arm or mounting locking assembly; after the two support arms are installed in parallel, they can temporarily support the equipment, allowing the installer to release their hands to complete the equipment fastening.

[0014] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figure 1 and Figure 2 As shown, the cabinet auxiliary installation support arm provided in this embodiment includes a support arm body, a hinge assembly 3, and two installation locking assemblies 5. The support arm body includes a first grooved half-arm 1 and a second grooved half-arm 2. The two grooved half-arms are connected by a hinge assembly 3 located between their opposite inner ends. The two installation locking assemblies 5 are located at opposite outer ends of the two grooved half-arms. In actual use, one support arm is connected between the front and rear cabinet uprights on one side of the cabinet; the other support arm is connected to the other side of the cabinet in the same manner. The two support arm bodies are at the same or corresponding height and are parallel to each other, together forming a lifting position for placing the equipment to be installed.

[0019] Both the first grooved half-arm 1 and the second grooved half-arm 2 can be formed by bending metal plates. Each grooved half-arm includes a supporting bottom wall 11 extending along the length direction and side flanges 12 that curve upward from both sides of the supporting bottom wall 11. The side flanges 12 and the supporting bottom wall 11 together form a grooved cross section. The inner end of each grooved half-arm is provided with a plurality of hinge connection holes 13, and the outer end is provided with an end limiting part 14 formed by partially bending the supporting bottom wall 11 and / or the side flanges 12. A plurality of weight-reducing holes 4 can be provided on the supporting bottom wall 11. In the illustrated embodiment, at least some of the weight-reducing holes 4 are combined to form a flower-shaped hole group arranged at intervals along the length direction.

[0020] The hinge assembly 3 includes a first hinge piece 31, a second hinge piece 32, and a pivot portion 33. The first hinge piece 31 is fixed to the first slotted half-arm 1 by a hinge fastener 34 passing through the corresponding hinge connection hole 13. The second hinge piece 32 is fixed to the second slotted half-arm 2 by the hinge fastener 34 passing through the corresponding hinge connection hole 13. The axis of the pivot portion 33 extends transversely to the length direction of the support arm body. The hinge fastener 34 can be a screw, bolt, or other detachable fastener.

[0021] When the support arm is in the extended position, the first grooved half-arm 1 and the second grooved half-arm 2 extend along the same straight line, and the supporting bottom walls 11 of the two grooved half-arms are flush or substantially flush to form a continuous support structure. Figure 1 As shown, during folding or unfolding, the two slotted half arms can rotate relative to each other around the pivot 33; after being fully folded, the two slotted half arms are adjacent and roughly parallel, thereby reducing the storage length.

[0022] like Figures 1 to 3 As shown, two mounting locking assemblies 5 are respectively disposed at opposite outer ends of the first grooved half-arm 1 and the second grooved half-arm 2. Each mounting locking assembly 5 includes a mounting base 51, an edge limiting part 6, a spring positioning pin 7, and a mounting fastener 8. The mounting base 51 can be formed by bending a sheet metal or by assembling multiple sheet metal pieces; the mounting base 51 includes a first clamping piece 52 and a second clamping piece 53, which are arranged at intervals to form a clamping space. The end limiting part 14 at the outer end of the grooved half-arm is adjacent to the mounting locking assembly 5 and is used to restrict the movement of the mounting locking assembly 5 or the equipment to be installed along the length direction of the support arm.

[0023] The edge limiting part 6 is located between the first clamping piece 52 and the second clamping piece 53, and can be formed as a short limiting piece with a length less than the two clamping pieces. When installing the support arm, the edge of the cabinet column or the plate area adjacent to the edge of the column enters the clamping space, and the edge limiting part 6 abuts against or engages with the edge of the column, thereby limiting the up-and-down sway of the installation locking assembly 5 relative to the cabinet column and the rotation around the spring positioning pin 7.

[0024] A spring-loaded locating pin 7 is located in the central area of ​​the mounting base 51 and includes a pin body 71, an operating head 72, and a return spring. The pin body 71 faces the cabinet upright, and the operating head 72 is located on the side for easy manual pulling. During installation, the operating head 72 is pulled first to retract the pin body 71. After the mounting base 51 is aligned with the cabinet upright, the operating head 72 is released, and the return spring pushes the pin body 71 into the corresponding mounting hole. The mounting hole can be a square hole, round hole, or oblong hole commonly found on cabinet uprights.

[0025] Each mounting base 51 is secured to the outer end of the corresponding slotted half-arm by three mounting fasteners 8. The three mounting fasteners 8 are preferably arranged in a triangular or triangular pattern, with two fasteners 8 located near the spring locating pin 7, and the third fastener 8 offset from the aforementioned two. This arrangement creates a stable surface connection, reducing the possibility of the mounting base 51 twisting, deforming, or misaligning relative to the slotted half-arm under stress.

[0026] When installing the equipment, first unfold the support arm and align the mounting locking components 5 at both ends with the two spaced-apart cabinet columns on the same side of the cabinet. Ensure that the edge limiting parts 6 at both ends are in a positioning engagement with the corresponding column edges, and insert the spring positioning pins 7 at both ends into the mounting holes at the same or corresponding heights. Then install the other support arm on the other side of the cabinet in the same manner. After confirming that both support arm bodies are at the same support height, place the equipment to be installed on the two support arm bodies. The installer can then release their hands, align the mounting ears, and insert the equipment fastening screws.

[0027] After the equipment is installed and secured, the clamping force on the two support arms can be slightly released. Then, pull the operating head 72 of each mounting locking component 5 to disengage the pin 71 from its corresponding mounting hole, thus separating the mounting base 51 from the cabinet column. The removed support arms can be folded and stored using the hinge assembly 3. Figure 3 As shown, the mounting locking components 5 at both ends are arranged adjacently after folding, making it easy to hold and store. If the mounting base 51, hinge assembly 3, or any slotted half-arm is damaged, the corresponding mounting fastener 8 or hinge fastener 34 can be removed and replaced.

[0028] The above embodiments are merely preferred embodiments of the present invention. For those skilled in the art, various modifications, substitutions, and improvements can be made without departing from the concept of the present invention, and all such modifications, substitutions, and improvements should fall within the protection scope of the present invention.

[0029] The above-described embodiments are merely one implementation of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this invention should be determined by the appended claims.
