Description

Technical Field

[0001] The invention relates to a switch line card fixing device, belonging to the technical field of servers. Background Art

[0002] A switch is a device that performs information exchange within a communication system. In computer network systems, the concept of switching represents an improvement to the shared operating mode. A hub is a shared device. The hub itself cannot identify the destination address. When host A transmits data to host B within the same local area network (LAN), the data packet is broadcast across the hub-based network. Each terminal verifies the address information in the packet header to determine whether to receive it. In this mode of operation, only one set of data frames can be transmitted on the network at a time, and retries are required if a collision occurs. This method shares network bandwidth.

[0003] The main functions of a switch include physical addressing, network topology, error checking, frame sequencing, and flow control. Switches now also have new features, such as support for VLANs (virtual local area networks), link aggregation, and even firewall capabilities.

[0004] The pluggable line card structure of a switch generally has two left and right auxiliary pull handles on the front end of the pluggable line card.

[0005] The disadvantage of this fixing method is that it requires both hands to operate simultaneously. If you mistakenly move the handle on only one side, it will cause uneven force, which may damage the chassis at the very least, or even damage the connector connecting the interface board and the backplane at the worst. The operation is very difficult and inefficient. Summary of the Invention

[0006] The object of the present invention is to address the above-mentioned problems and provide a switch line card fixing device that saves time and effort in assembly and disassembly and can avoid damage.

[0007] The present invention is achieved through the following technical solutions:

[0008] A switch line card fixing device includes a line card tray, a panel provided at the end of the line card tray, two handles provided on the front end of the panel, rail brackets fixed to the upper ends of both sides of the line card tray, the rail brackets having a plurality of limiting holes and arc holes, a locking rod movably provided in the rail brackets, the locking rod having an equal number of limiting pins and locking hooks, the locking hooks being located in the limiting holes, and the limiting pins being located in the arc holes;

[0009] A driving arm is hinged between the ends of the two locking rods close to the panel. A screw and nut mechanism is installed on the panel. The nut is connected to the driving arm. Rotating the screw realizes the linear movement of the nut and the driving arm.

[0010] Utilizing a screw-nut mechanism, rotating the screw drives the nut to drive the drive arm, which in turn drives the two locking rods inward. The limit pin slides inward along the arc-shaped hole, and the locking hook retracts into the limit hole, unlocking the line card tray. Rotating the screw in the other direction causes the limit pin to slide outward along the arc-shaped hole, and the locking hook extends from the limit hole and inserts into the chassis, locking the line card tray. The present invention manually rotates the screw, and the screw-nut pair drives the left and right locking rods to enable the insertion and removal of switch line cards, while also securing the line cards to the chassis. This convenient operation saves time and effort. The left and right locking hooks operate synchronously, preventing torque deflection and preventing connector damage.

[0011] A further improvement of the present invention is that a front bracket is fixedly embedded in the middle of the lower end of the panel. A thumb screw is threaded onto the front bracket, and a driving slider is mounted on the thumb screw. The driving slider is connected to a driving arm. By turning the thumb screw, the driving slider drives the driving arm to move, and the driving arm in turn drives the left and right locking rods to achieve the transition between the retracted and extended states of the lock hook. The structure is simple and the operation is convenient.

[0012] A further improvement of the present invention is that the driving slider is cross-shaped, the driving arm is composed of two plates, and the upper and lower parts of the driving slider pass through the two plate driving arms. The driving slider drives the two plate driving arms to move back and forth, and the stability of the driving structure is improved.

[0013] A further improvement of the present invention is that a cover plate is provided on the drive arm, and a guide hole is defined in the cover plate. The upper portion of the drive slider extends through the guide hole. One end of the lower portion of the cover plate is fixedly connected to the line card tray, and the other end of the lower portion of the cover plate is connected to the front bracket. The cover plate covers the drive arm and limits the movement of the drive arm. The upper portion of the drive slider moves within the guide hole, providing both a limit and a guide.

[0014] A further improvement of the present invention is that the driving slider is cross-shaped, the driving arm is composed of two plates, the upper and lower parts of the driving slider pass through the two plate driving arms, and the upper part of the driving slider extends out from the guide hole of the cover plate.

[0015] A further improvement of the present invention is that strip holes are opened on the cover plate and the line card tray, and a directional insert is fixed on the cover plate, the upper part of the directional insert is located in the strip hole of the cover plate, and the lower part of the directional insert is located in the strip hole of the line card tray.

[0016] A further improvement of the present invention is that strip holes are formed in the cover plate and the line card tray, and a cross-shaped directional insert is fixed to the cover plate. The upper portion of the directional insert passes through the two plates, and the driving arm is located in the strip hole of the cover plate. The lower portion of the directional insert passes through the two plates, and the driving arm is located in the strip hole of the line card tray. The cross-shaped directional insert is used to connect the driving arm, the cover plate, and the line card tray, allowing the driving arm to slide back and forth in the strip holes of the cover plate and the limit tray.

[0017] A further improvement of the present invention is that a track pad is mounted on the lock rod via a limit pin. The track pad is a C-shaped structure and covers the outside of the lock rod, thereby avoiding direct contact between the lock rod and the track bracket and reducing friction.

[0018] A further improvement of the present invention is that the track bracket is provided with protrusions having the same number as the arc-shaped holes, and the protrusions extend inwardly, so as to provide sufficient space for the arc-shaped holes.

[0019] A further improvement of the present invention is that two handles are provided on the outer end surface of the panel, and the operator can hold the handles to make plugging and unplugging more convenient.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] Utilizing a screw-nut mechanism, rotating the screw drives the nut to drive the drive arm, which in turn drives the two locking rods inward. The limit pin slides inward along the arc-shaped hole, and the locking hook retracts into the limit hole, unlocking the line card tray. Rotating the screw in the other direction causes the limit pin to slide outward along the arc-shaped hole, and the locking hook extends from the limit hole and inserts into the chassis, locking the line card tray. The present invention manually rotates the screw, and the screw-nut pair drives the left and right locking rods to enable the insertion and removal of switch line cards, while also securing the line cards to the chassis. This convenient operation saves time and effort. The left and right locking hooks operate synchronously, preventing torque deflection and preventing connector damage.

[0031] Example 1:

[0032] like Figures 1 to 6 The illustrated device for securing switch line cards includes a line card tray 1, with a panel 2 provided at one end and two handles 3 provided on the front end of the panel 2. Rail brackets 9 are fixed to the upper ends of both sides of the line card tray 1. The rail brackets 9 are provided with a plurality of limiting holes 11 and arc-shaped holes 10. A locking rod 7 is movably disposed within the rail bracket 9. The locking rod 7 is provided with an equal number of limiting pins 13 and locking hooks 12.

[0033] A driving arm 5 is hinged between the two locking rods 7 at one end close to the panel 2. A screw and nut mechanism is installed on the panel 2. The nut is connected to the driving arm 5. The linear movement of the nut and the driving arm is achieved by rotating the screw.

[0034] Utilizing the screw-nut mechanism, rotating the screw drives the nut to drive the drive arm 5, which in turn drives the two locking rods 7 to move inward, causing the limit pin 13 to slide inward along the arc-shaped hole 10, and the locking hook 12 to retract into the limit hole 11, thereby opening the line card tray 1. Rotating the screw in the other direction causes the limit pin 13 to slide outward along the arc-shaped hole 10, and the locking hook 12 to extend from the limit hole 11 and insert into the chassis, thereby locking the line card tray 1. The present invention manually rotates the screw, and the screw-nut pair drives the left and right locking rods 7 to enable the insertion and removal of switch line cards, while also securing the line cards to the chassis.
