A wall mount bracket assembly for equipment cabinet installation

Abstract

This utility model discloses a wall-mounted bracket assembly for installing equipment enclosures, including a mounting component for fixing on a mounting surface, a first locking component fixedly connected to the mounting component, and a second locking component fixed to the back of the enclosure and forming a guide groove together with the back of the enclosure. The first locking component has an elongated square hole and an elastic element that can be elastically reset at one end.

During installation, the second locking component is aligned and inserted into the first locking component, and the elastic element is compressed back; when the mounting component's limiting baffle and the equipment enclosure side panel are in contact, the elastic element resets and engages in the limiting hole, achieving locking and fixation. During disassembly, pressing the elastic element disengages the first and second locking components. This utility model achieves tool-free quick assembly and disassembly of the mounting component, has a simple and reliable structure, does not occupy internal space of the enclosure, and does not affect the enclosure's shape or sealing performance, effectively reducing production and maintenance costs.

Description

Technical Field

[0001] This utility model relates to a wall-mounted bracket assembly for installing equipment enclosures, and more particularly to a wall-mounted bracket assembly for installing equipment enclosures in rail transit video surveillance systems. Background Technology

[0002] In urban rail transit communication engineering, video surveillance system equipment boxes typically need to be wall-mounted in equipment rooms or signal towers to save space. Traditional wall-mounting methods mainly fall into two categories: The first is direct fixing, such as drilling bolt holes on the back of the box or directly welding the bracket to the box. This method compromises the overall airtightness of the box and requires reserved operating space inside, reducing space utilization. The second is indirect fixing, where independent wall-mounted brackets are fixed to mounting holes on the back of the box using bolts. While this method does not compromise the seal, welded or externally mounted brackets protrude from the box's shape, significantly increasing product packaging size and transportation costs. Furthermore, the brackets are easily deformed or damaged during logistics due to compression and collisions, causing inconvenience for on-site construction. Utility Model Content

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0022] As shown in the attached figure, this utility model includes an installation component 1, a first locking component 2, and a second locking component 9, which can achieve quick installation and disassembly through a mechanical snap-fit ​​structure.

[0023] Mounting component 1 is made of ordinary cold-rolled steel sheet, preferably L-shaped. A gourd-shaped mounting hole is punched on its vertical surface, facilitating installation with expansion bolts 13 on the wall and allowing for fine-tuning. Welding positioning holes 6 are provided on its horizontal surface.

[0024] The first locking component 2 is made of cold-rolled steel plate. One end has a welded positioning groove 8 machined for alignment with the positioning hole 6 on the horizontal surface of the mounting component 1, ensuring welding accuracy. The other end is bent to form a dead edge and machined with a trapezoidal guide structure 7 for easy insertion. A long rectangular hole 4 is punched in the middle of the first locking component 2. A cantilever beam-type elastic component 5 is provided at one end of this long rectangular hole near the trapezoidal guide structure 7. The bottom of this elastic component 5 is connected to the wall of the long rectangular hole 4, and the other end protrudes upwards in its natural state, providing good elastic reset function.

[0025] The first locking member 2 is aligned with the welding positioning hole 6 of the mounting member 1 through its welding positioning groove 8, and the two are firmly welded together by welding process to form a suspension bracket.

[0026] The second locking member 9 is made of cold-rolled steel strip, formed into a channel-shaped guide structure, and welded to the back of the equipment box 11, forming a guide groove together with the back of the equipment box 11. At least one limiting hole 10 is provided on its top plate. The position and size of the limiting hole 10 match the elastic element 5 on the first locking member 2.

[0027] The installation of this utility model is divided into two stages: component fixing and box mounting.

[0028] Component fixing stage (tool-free operation):

[0029] Align the opening of the second locking member 9 on the back of the housing to be installed with the trapezoidal guide structure 7 of the first locking member 2. Insert the first locking member 2 into the second locking member 9 along the inclined surface of the trapezoidal guide structure 7. During this process, the inner wall of the top plate of the second locking member 9 will press against the free end of the elastic member 5, causing it to elastically deform and completely contract into the elongated square hole 4, thereby opening a passage so that the first locking member 2 can be smoothly inserted into the second locking member 9.

[0030] When the first locking member 2 slides along the cavity wall between the second locking member 9 and the back of the housing 11 until the limiting plate of the mounting member 1 and the side plate of the housing are tightly fitted, the elastic member 5 moves just below the limiting hole 10 on the top surface of the second locking member 9.

[0031] At this point, the elastic element 5 loses external pressure and quickly returns to its original position by its own elasticity, locking into the limiting hole 10. This action creates a mechanical lock. Due to the obstruction of the elastic element, the first locking element 2 can no longer be pulled out from the second locking element 9, and the installation is complete. The component installation process requires no tools and is quick and reliable.

[0032] Container mounting stage:

[0033] During on-site installation, drill fixing holes on the wall or mounting surface 12, and use expansion bolts to pass through the large gourd-shaped part on the mounting component. Slide the box 11 down until the threaded rod of the expansion bolt 13 and the uppermost end of the gourd-shaped part are in contact. Then tighten the nut to ensure that the box is installed firmly.

[0034] Disassembly process (tool-free operation):

[0035] When it is necessary to disassemble or replace the mounting parts, the construction personnel only need to press the protruding part of the elastic element 5 directly inward by hand. At this time, the elastic element 5 retracts back into the elongated square hole, and the elastic element 5 is released from the restraint of the limiting hole 10. Then, the mounting part 1 can be pulled outward to be removed from the box.
