Description

Technical Field

[0001] This utility model relates to the field of storage rack technology, specifically a multi-layer storage rack that can prevent circuit boards from colliding. Background Technology

[0002] Multi-layer PCB storage racks typically refer to tools or equipment specifically designed for storing multi-layer printed circuit boards (PCBs). Their main function is to store multi-layer PCBs in an orderly and safe manner to prevent damage or deformation, and to facilitate retrieval and management.

[0003] In the prior art, during transportation, the surface of the circuit board is easily exposed to hard materials, which may cause scratches on the surface of the circuit board and affect its subsequent use.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN203419420U) discloses a circuit board storage rack, which includes a square frame made of stainless steel plate, with a number of horizontal partitions evenly spaced inside the square frame, dividing the square frame into a number of storage layers, and a number of vertical partitions evenly spaced inside the storage layers, the longitudinal section of the vertical partitions being an isosceles trapezoid. The circuit board storage rack has the advantages of simple structure, convenient use, small space occupation, and effective prevention of scratches or abrasions on the surface of the circuit board.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation. For example, when circuit boards are transported inside the storage rack, they are prone to collisions and damage as the rack moves, which is not conducive to the transportation of circuit boards. Utility Model Content

[0006] The purpose of this invention is to provide a multi-layer storage rack that can prevent circuit boards from colliding, thereby solving the problem mentioned in the background art that when circuit boards are transported inside the storage rack, they are prone to collision and damage as the storage rack moves, which is not conducive to the transportation of circuit boards.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer storage rack that can prevent circuit board collisions, comprising a rack body and a base provided at the lower end of the rack body, wherein a positioning compartment is installed on the inner wall of the rack body, and a printed circuit board is provided on the inner side of the positioning compartment; the upper and lower ends of the positioning compartment are correspondingly arranged, and an anti-shaking mechanism is provided inside the positioning compartment; an irregularly shaped horizontal plate is installed at the upper end of the rack body by bolts, and an auxiliary positioning mechanism is installed on the surface of the irregularly shaped horizontal plate.

[0008] Furthermore, a base is fixedly installed at the bottom of the frame, and auxiliary casters are provided at the bottom of the base, with the auxiliary casters symmetrically arranged at the four corners.

[0009] Furthermore, the anti-sway mechanism is equipped with a damper, which is fixedly installed inside the frame. An abutment plate is provided on the inner side of the damper, and the front end of the abutment plate is inclined. The abutment plate and the printed circuit board form a pressing structure.

[0010] Furthermore, a buffer spring is installed on the outer side of the abutment plate, and the outer side of the buffer spring is located on the inner wall of the frame.

[0011] Furthermore, the auxiliary positioning mechanism is provided with a limiting sleeve, and the rear end of the limiting sleeve is fixedly installed at the front end of the frame. An auxiliary partition is installed through the inside of the limiting sleeve, and a torsion spring is provided between the auxiliary partition and the limiting sleeve. A soft pad layer is fixedly installed on the inner wall of the auxiliary partition, and the auxiliary partition corresponds to the printed circuit board.

[0012] Furthermore, a fixing compartment is installed at the front end of the irregular horizontal plate, and a pull rod is installed through the upper end of the fixing compartment. A vertical pole is fixedly installed at the lower end of the pull rod, and an inclined locking block is fixedly installed at the lower end of the vertical pole.

[0013] Furthermore, a pressure spring is sleeved on the surface of the pull rod, and the upper and lower ends of the pressure spring are located between the upright and the fixed chamber. The lower end of the upright passes through the irregular horizontal plate, and the lower end of the tilting locking block corresponds to the auxiliary partition.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. During use, the storage rack can be moved by the auxiliary casters at the bottom of the frame and base. When storing the circuit board, the edge of the printed circuit board is inserted into the positioning compartment, so that the printed circuit board is located inside the abutment plate. The front end of the abutment plate is tilted to assist in insertion and improve the ease of insertion. At the same time, after the printed circuit board is inserted into the abutment plate, the setting of buffer spring and damper can assist in positioning, further improving the stability of the circuit board during transportation inside the storage rack and preventing the circuit board from being damaged by collision.

[0016] 2. When the printed circuit board is located inside the abutment plate, an auxiliary partition is set by rotating inside the limiting sleeve. Under the action of the torsion spring, the auxiliary partition can fit the printed circuit board. At the same time, a soft pad layer is set on the inside of the printed circuit board to help block and protect the printed circuit board, prevent the printed circuit board from falling during transportation, and provide efficient protection for the printed circuit board.

[0017] Furthermore, an irregularly shaped horizontal plate is installed at the upper end of the frame, and two self-locking structures are installed at the front end of the irregularly shaped horizontal plate. When the auxiliary partition is opened, by moving the auxiliary partition, it can be automatically locked and positioned by the pressure spring after passing the inclined locking block. When the pull rod is pulled, the auxiliary partition automatically closes. With the setting of the two sets of locking mechanisms, the auxiliary partition is automatically locked when it is automatically closed or opened, which improves stability and makes the operation simple and convenient.

[0027] In use, the storage rack can be moved by the auxiliary casters at the bottom of the frame 1 and the base 2. When storing the circuit board, the edge of the printed circuit board 4 is inserted into the positioning compartment 3, so that the printed circuit board 4 is located inside the abutment plate 6. The front end of the abutment plate 6 is tilted to assist in the insertion and improve the ease of insertion. After the printed circuit board 4 is inserted into the abutment plate 6, the buffer spring 5 and the damper 7 are set to assist in positioning, further improving the stability of the circuit board during transportation inside the storage rack and preventing the circuit board from being damaged by collision.
