[0001] This utility model relates to the field of circuit board insertion frame technology, specifically a combined circuit board insertion frame. Background Technology

[0002] A circuit board rack is a support structure used to store circuit boards. It can hold multiple circuit boards, reducing the time spent on manual handling and storage, improving production efficiency, and is widely used in the electronics manufacturing industry.

[0003] Existing patent application number: 202120230679.9 A circuit board insertion rack, which uses multiple grooves provided on the upper end of multiple boards to allow circuit boards to be inserted vertically, making it convenient for workers to insert them while maintaining a gap between the circuit boards to prevent them from being damaged due to friction between them.

[0004] The aforementioned patent describes a circuit board insertion rack. However, in practical applications, the insertion racks lack the ability to be combined. When transporting multiple fully loaded insertion racks, it is difficult to stack and combine them to save space, which causes some inconvenience to the transportation work. Therefore, we propose a modular circuit board insertion rack to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a combined circuit board insertion rack to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a combined circuit board insertion frame, including an insertion frame, PCB slots, and a stacking assembly mechanism. The top surface of the insertion frame has horizontally arranged PCB slots. The left and right sides of the insertion frame have stacking assembly mechanisms, each including a rear slot, a front slot, a rear connecting slot, a rear insertion rod, a front connecting slot, a front insertion rod, and a locking mechanism. The rear slots are symmetrically arranged on the top rear portion of the left and right sides of the insertion frame, and the front slots are symmetrically arranged on the top front portion of the left and right sides of the insertion frame. The rear slots and the front insertion rods... The slots are vertically arranged. The bottom surfaces of the left and right sides of the insert plate frame are symmetrically arranged with rear connecting slots. The first end of the rear connecting slot is elastically rotatably connected to the rear insert rod by a torsion spring shaft. The bottom surfaces of the left and right sides of the insert plate frame are symmetrically arranged with front connecting slots. The first end of the front connecting slot is elastically rotatably connected to the front insert rod by a torsion spring shaft. The rear connecting slots and the front connecting slots are horizontally arranged. The rear insert rod can be longitudinally inserted into the inner side of the rear slot, and the front insert rod can be longitudinally inserted into the inner side of the front slot. The ends of the rear connecting slots and the front connecting slots are provided with locking mechanisms.

[0007] Preferably, the height of the rear insertion rod and the front insertion rod in the stored state is not lower than the height of the bottom surface of the insertion plate frame.

[0008] Preferably, the maximum rotation angle of both the rear insertion rod and the front insertion rod is 90 degrees.

[0009] Preferably, the depth of both the rear slot and the front slot is ≥2cm.

[0010] Preferably, the locking mechanism includes a lock hole, a pin groove, a sliding pin, a spring, a slide groove, and a sliding button. Both the rear and front insert rods have lock holes at their ends. Both the rear and front connecting grooves have pin grooves at their ends. A sliding pin is slidably installed inside the pin groove, and the end of the sliding pin can slide out of the pin groove and engage with the lock hole. A spring is installed at the head of the sliding pin, and the tail end of the spring is connected to the pin groove. Slide grooves are symmetrically arranged on the left and right side walls of the insert plate frame. The slide grooves are horizontal and communicate with the pin groove. A sliding button is slidably installed inside the slide groove, and the sliding button establishes a transmission connection with the sliding pin.

[0011] Preferably, the end of the sliding pin is designed with a bevel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a stacking and combining mechanism on the left and right sides of the insert rack. When the insert racks need to be stacked longitudinally, the upper insert rack can retract its sliding pin into the pin groove via a sliding button, thus disengaging the sliding pin from the locking hole. At this time, the rear insert rod, driven by the elasticity of the torsion spring shaft, disengages from the rear connecting groove and flips downwards. Similarly, the front insert rod, driven by the elasticity of the torsion spring shaft, also disengages from the front connecting groove and flips downwards. Finally, the rear insert rod is aligned with the rear slot and the front insert rod is aligned with the front slot, thereby achieving longitudinal stacking and combining of the insert racks, effectively saving space and enabling more efficient handling and storage.

[0014] This utility model features a locking mechanism at the ends of the rear and front connecting slots. By flipping the rear insert rod upward and pushing it back into the rear connecting slot, and pushing the front insert rod upward and pushing it back into the front connecting slot, a spring provides a spring-loaded ejection force to the sliding pin, causing the sliding pin to slide out of the pin slot and engage with the locking hole. This keeps the rear and front insert rods in a retracted state, without affecting the normal placement and use of a single insert plate holder. Attached Figure Description

Detailed Implementation

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 This utility model provides a combined circuit board insertion rack, including an insertion rack 1, PCB slots 2 and a stacking and combining mechanism 3. The PCB slots 2 are arranged horizontally on the top surface of the insertion rack 1, and the stacking and combining mechanism 3 is arranged on the left and right sides of the insertion rack 1.

[0023] Please see Figure 2-3 This utility model provides a combined circuit board insertion rack. The stacking and combining mechanism 3 includes a rear slot 31, a front slot 32, a rear connecting groove 33, a rear insertion rod 34, a front connecting groove 35, a front insertion rod 36, and a locking mechanism 37. The rear slots 31 are symmetrically arranged on the top surface of the rear part of the left and right sides of the insertion rack 1, and the front slots 32 are symmetrically arranged on the top surface of the front part of the left and right sides of the insertion rack 1. The rear slots 31 and the front slots 32 are perpendicular to each other. The rear connecting grooves 33 are symmetrically arranged on the bottom surface of the rear part of the left and right sides of the insertion rack 1. The first end of the rear connecting groove 33 is equipped with a torsion spring. The shaft and the rear insertion rod 34 are elastically rotatably connected. The front bottom surface of the left and right sides of the insertion plate frame 1 is symmetrically provided with a front connecting groove 35. The first end of the front connecting groove 35 is elastically rotatably connected to the front insertion rod 36 by a torsion spring shaft. The rear connecting groove 33 and the front connecting groove 35 are horizontally set. The rear insertion rod 34 can be longitudinally inserted into the inner side of the rear slot 31, and the front insertion rod 36 can be longitudinally inserted into the inner side of the front slot 32, thereby realizing the longitudinal stacking combination between the insertion plate frames 1. The rear connecting groove 33 and the front connecting groove 35 are provided with a locking mechanism 37.

[0024] To further clarify, the height of the rear insertion rod 34 and the front insertion rod 36 in the stored state is not lower than the bottom surface of the insertion plate rack 1, and will not affect the normal placement of a single insertion plate rack 1.

[0025] To further explain, the maximum rotation angle of both the rear insert rod 34 and the front insert rod 36 is 90 degrees, allowing them to rotate into place in one go without the need for installation angle adjustment.

[0026] To further explain, the depth of both the rear slot 31 and the front slot 32 is ≥2cm, ensuring the connection strength between the insert brackets 1 and preventing accidental loosening and detachment.

[0027] Please see Figure 4-5 This utility model provides a combined circuit board insertion bracket. The locking mechanism 37 includes a lock hole 371, a pin groove 372, a sliding pin 373, a spring 374, a slide groove 375, and a sliding button 376. The ends of the rear insertion rod 34 and the front insertion rod 36 are both provided with lock holes 371. The ends of the rear connecting groove 33 and the front connecting groove 35 are both provided with pin grooves 372. The sliding pin 373 is slidably installed inside the pin groove 372, and the end of the sliding pin 373 can slide out of the pin groove 372. The sliding pin 373 is inserted into the lock hole 371. A spring 374 is installed at the first end of the sliding pin 373. The tail end of the spring 374 is connected to the pin groove 372. The spring 374 provides a return force for the sliding pin 373. The left and right side walls of the insert plate frame 1 are symmetrically provided with sliding grooves 375. The sliding grooves 375 are horizontally set and are connected to the inside of the pin groove 372. A sliding button 376 is slidably set inside the sliding groove 375. The sliding button 376 establishes a transmission connection with the sliding pin 373.

[0028] To further explain, the end of the sliding pin 373 is designed with a bevel, which allows the rear insert rod 34 and the front insert rod 36 to push the sliding pin 373 back into the pin groove 372 through the bevel when flipped and retracted, eliminating the need for frequent operation of the sliding button 376 and making it more convenient to use.

[0029] The working principle is as follows:

[0030] First, when in use, the circuit board can be vertically inserted and placed inside the PCB slot 2. The board rack 1 can accommodate multiple circuit boards through the PCB slot 2 for easy handling and storage.

[0031] Secondly, by setting up a stacking and combination mechanism 3 on the left and right sides of the insert plate rack 1, when the insert plate rack 1 needs to be stacked longitudinally, the upper insert plate rack 1 can control the sliding pin 373 to retract into the pin groove 372 through the sliding button 376, so as to release the connection between the sliding pin 373 and the lock hole 371. At this time, the rear insert rod 34 will disengage from the rear connecting groove 33 and flip down under the elastic drive of the torsion spring shaft. Similarly, the front insert rod 36 will also disengage from the front connecting groove 35 and flip down under the elastic drive of the torsion spring shaft. Finally, the rear insert rod 34 is aligned with the rear slot 31 for insertion and the front insert rod 36 is aligned with the front slot 32 for insertion, thereby realizing the longitudinal stacking and combination between the insert plate racks 1, effectively saving space and enabling more efficient handling and storage.

[0032] Third, when the insert rack 1 is used alone, the rear insert rod 34 is flipped upward and pushed back into the rear connecting groove 33, and the front insert rod 36 is pushed upward and pushed back into the front connecting groove 35. The spring 374 provides pop-out force for the sliding pin 373, causing the sliding pin 373 to slide out of the pin groove 372 and engage with the locking hole 371, thereby keeping the rear insert rod 34 and the front insert rod 36 in a stored state, which will not affect the normal placement and use of a single insert rack 1.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
