Description

Technical Field

[0001] This utility model relates to the field of rack technology, specifically a metal rack that is easy to assemble. Background Technology

[0002] Metal racks are frame structures used to support and secure various equipment, components, and systems. They are typically made of metal materials such as steel, aluminum, or stainless steel. Metal racks are widely used in electronic equipment, machinery, communication equipment, and automation systems. Currently, metal racks are mostly assembled by splicing profiles. During the end-to-end splicing of these profiles, a certain number of auxiliary accessories (such as L-shaped connectors, T-shaped connectors, cross-shaped connectors, or angle aluminum connectors) are required for connection, making the installation process relatively cumbersome and time-consuming, thus increasing the assembly workload. Summary of the Invention

[0003] The purpose of this invention is to provide a metal frame that is easy to assemble, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a metal frame that is easy to assemble, comprising multiple profiles with vertically spliced ​​ends, the profiles being spliced ​​together at both ends to form a frame by fastening screws, a support plate being installed in the middle of the frame by a support member, threaded holes being provided at the center of both ends of the profiles along the axial direction, and through holes for fastening tools to pass through being provided on all four sides of one end of the profiles perpendicular to the threaded holes; when the ends of two profiles are aligned vertically, the through holes and threaded holes are positioned correspondingly.

[0005] The support includes a limiting slider installed in the middle of the profile. A sliding sleeve is slidably connected to one side of the limiting slider. A pressure part is provided at one end of the sliding sleeve for driving the sliding sleeve to cooperate with the profile for positioning.

[0006] Preferably, the profile is a square structure, and each of the four sides of the profile has a limiting groove, which is a polygonal structure.

[0007] Preferably, a limiting notch is provided at the position of the limiting groove corresponding to the profile for bolts to pass through.

[0008] Preferably, the limiting slider is slidably connected to the limiting slot, and a connecting hole is provided in the middle of the limiting slider.

[0009] Preferably, a connecting rod is fixed to one side of the limiting slider, and a connecting hole three is opened in the middle of the connecting rod. The sliding sleeve is slidably installed on the outside of the connecting rod, and a connecting hole two corresponding to the connecting hole three is opened in the middle of the sliding sleeve.

[0010] Preferably, the pressure part includes a limiting plate fixed to one end of the connecting rod, a limiting rod fixed to one side of the limiting plate, a spring sleeved on the outside of the limiting rod for pressing the sliding sleeve against the outside of the profile, and a limiting hole corresponding to the spring at one end of the sliding sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: threaded holes are opened at the center of both ends of the profile along the axial direction, and through holes are opened on the four sides of both ends perpendicular to the threaded holes. During splicing, after the fastening screw is threadedly connected to the threaded hole of one profile, it is slid into the interior of the other profile. When the sides and ends of the two profiles are in contact, the through holes correspond to the threaded holes. The fastening screw can be tightened by passing a tool through the through holes, realizing the vertical splicing of the two profiles. This reduces the use of corresponding accessories, simplifies the operation steps, and enables the rapid assembly of a rectangular frame, thereby constructing a metal frame and improving assembly efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 , 2As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a metal frame that is easy to assemble, comprising multiple profiles 1 with vertically spliced ​​ends. The profiles 1 are spliced ​​together at both ends to form a frame by fastening screws 7. Washers are fitted on the outer side of the fastening screws 7, and the fastening screws 7 are self-locking bolts. A support plate 6 is installed in the middle of the frame by a support member. Threaded holes 4 that mate with the fastening screws 7 are provided at the center of both ends of the profiles 1 along the axial direction. Through holes 5 for fastening tools to pass through are provided on all four sides of one end of the profiles 1 perpendicular to the threaded holes 4. When the ends of two profiles 1 are aligned vertically, the through holes 5 correspond to the threaded holes 4. The support member includes a limiting slider 8 installed in the middle of the profiles 1. A sliding sleeve 12 is slidably connected to one side of the limiting slider 8. A pressure part is provided at one end of the sliding sleeve 12 for driving the sliding sleeve 12 to cooperate with the profiles 1 for positioning.

[0020] It should be noted that in this embodiment, the fastening screw 7 is threadedly connected to the threaded hole 4 of the profile 1, allowing the fastening screw 7 to slide into the interior of the profile 1 along one end of the other profile 1. When the side of the profile 1 is in contact with the end of the other profile, the fastening screw 7 inside the threaded hole 4 corresponds to the through hole 5. The tool is then used to pass through the through hole 5 and connect to the fastening screw 7, thereby tightening the fastening screw 7. The two profiles 1 are then vertically spliced ​​together. By doing this operation, the four profiles 1 are assembled into a rectangular frame. Then, the remaining profiles 1 with the fastening screw 7 installed at the end are placed vertically on the top of the frame. The fastening screw 7 is then slid into the frame, and the workpiece is then passed through the through hole 5 to tighten the fastening screw 7, thereby assembling the profiles 1 into a metal frame.

[0021] In one embodiment, the profile 1 is a square structure, and each of the four sides of the profile 1 is provided with a limiting groove 2. The limiting groove 2 is a polygonal structure, and a limiting notch 3 is provided at the position of the limiting groove 2 of the profile 1 for the bolt to pass through.

[0022] It should be noted that in this embodiment, the polygonal structure is a combination of an isosceles trapezoid and a rectangle. The limiting slot 2 and the limiting slider 8 are slidably connected. The width of the limiting notch 3 is adapted to the thread diameter of the fastening screw 7. The head diameter of the fastening screw 7 is smaller than the width of the limiting slot 2 and larger than the width of the limiting notch 3. Thus, the head of the fastening screw 7 can be locked in the limiting slot 2. In this way, the two perpendicular parts are connected and fastened with the cooperation of the fastening screw 7 and the threaded hole 4.

[0023] In one embodiment, the limiting slider 8 is slidably connected to the limiting slot 2, and the limiting slider 8 has a connecting hole 9 in its middle. A connecting rod 10 is fixedly connected to one side of the limiting slider 8, and a connecting hole 14 is opened in the middle of the connecting rod 10. A sliding sleeve 12 is slidably installed on the outside of the connecting rod 10, and a connecting hole 13 corresponding to the connecting hole 14 is opened in the middle of the sliding sleeve 12. The pressure part includes a limiting plate 11 fixedly connected to one end of the connecting rod 10. A limiting rod 16 is fixedly connected to one side of the limiting plate 11, and a spring 15 is sleeved on the outside of the limiting rod 16 to press the sliding sleeve 12 against the outside of the profile 1. A limiting hole 17 corresponding to the spring 15 is opened at one end of the sliding sleeve 12. The side of the sliding sleeve 12 near the limiting slider 8 has a frosted surface.

[0024] It should be noted that, in this embodiment, before assembling and installing the profile 1, a corresponding number of limiting sliders 8 are slid into one end of the limiting slot 2. During this period, the sliding sleeve 12 slides along the connecting rod 10 toward one end of the limiting plate 11. The sliding sleeve 12 compresses the spring 15 on the outside of the limiting rod 16 through the limiting hole 17, thereby separating one end of the sliding sleeve 12 from the profile 1. When the limiting slider 8 slides to the designated position, the restraint on the sliding sleeve 12 is released. Under the elastic force of the spring 15, the limiting slider... 8 is attached to the profile 1. Under the action of friction, the sliding sleeve 12 limits the limiting slider 8 to the designated position. Thus, the second connecting hole 13 corresponds to the third connecting hole 14. A washer is put on the outside of the bolt and its end is inserted from the limiting slot 2 and threaded into the first connecting hole 9 to fix the limiting slider 8. The support plate 6 is placed on the top of the sliding sleeve 12. Then, the bolt passes through the middle of the second connecting hole 13 and the third connecting hole 14 and is threaded into the support plate 6 to limit and fix the support plate 6.
