[0001] The utility model relates to the field of boards and cards, and specifically provides a handle for a board and card, and a board and card. Background Art

[0002] With the increasing number of electronic components in various devices, chassis are often installed to ensure a safe working environment for these components. Furthermore, these components are installed on boards in a highly modular and integrated manner. By electrically connecting the boards to the chassis, these electronic components can control other devices in the device.

[0003] Due to the need for repair and maintenance, the board needs to be plugged in and out frequently. When the equipment is in use, the board also needs to be locked. The process of installing and removing the board in the existing technology is complicated, affecting the installation and removal efficiency of the operator.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0005] In order to solve the problem of low installation and removal efficiency between a board and a chassis in the prior art, the present invention provides a handle for a board. The handle of the present invention comprises: a gripping body, the gripping body comprising a first end and a second end opposite to each other, at least one of the first end and the second end being provided with a mounting slot; a locking assembly, the locking assembly being disposed in the mounting slot and comprising a locking pin and an elastic member, wherein in a locked state of the locking assembly, at least a portion of the locking pin extends beyond an opening of the mounting slot, and in an unlocked state of the locking assembly, the locking pin is accommodated within the mounting slot, and when the gripping body moves in a predetermined direction, the gripping body drives the locking pin to move into the mounting slot and compresses the elastic member, thereby enabling the locking assembly to switch from a locked state to an unlocked state; and when the gripping body moves in a direction opposite to the predetermined direction, the elastic member expands and drives the locking pin to move out of the mounting slot, thereby enabling the locking assembly to switch from the unlocked state to the locked state.

[0006] The handle of the present invention includes a gripping body comprising a first end and a second end, at least one of which is provided with a mounting slot. The mounting slot is configured to receive a locking assembly, allowing the handle to be locked and unlocked from the chassis from one or both sides of the card. The locking assembly comprises a locking pin and an elastic member. In the locked state, at least a portion of the locking pin extends beyond the opening of the mounting slot to facilitate its reception in a corresponding locking hole in the chassis. In the unlocked state, the locking pin is received in the mounting slot, allowing it to separate from the corresponding locking hole in the chassis, allowing the card to be removed from the chassis. When the gripping body is moved in a predetermined direction, the gripping body drives the locking pin toward the inside of the mounting slot and compresses the elastic member, causing the locking assembly to switch from the locked state to the unlocked state. When the gripping body is moved in a direction opposite to the predetermined direction, the elastic member expands and drives the locking pin out of the mounting slot, causing the locking assembly to switch from the unlocked state to the locked state. With this arrangement, an operator can unlock the card by controlling the gripping body to move in the predetermined direction, and lock the card by moving in the opposite direction, thereby improving the efficiency of installing and removing the card from the chassis.

[0007] In the preferred technical solution of the above-mentioned handle, the locking assembly further includes a guide sleeve sleeved on the outside of the locking pin; the mounting groove includes a guide groove, the guide groove extending along the predetermined direction and including a first side wall and a second side wall. In the locked state, the guide sleeve abuts against the first side wall; in the unlocked state, the guide sleeve abuts against the second side wall. Through the above-mentioned arrangement, the first side wall and the second side wall limit the movement of the guide sleeve. When the guide sleeve abuts against the first side wall, the force applied to the grip body can also act on the guide sleeve, so that the board can be more firmly connected to the chassis; when the guide sleeve abuts against the second side wall, the force applied to the grip body can also act on the guide sleeve, so that the board can be removed from the chassis.

[0008] In a preferred embodiment of the handle, the handle further comprises a connector fixedly connected to the guide sleeve, the connector being adapted to connect to a card. With this arrangement, the connector and the guide sleeve move synchronously, allowing the card to be removed in the unlocked state; in the locked state, the connector remains fixedly connected to the chassis.

[0009] In the preferred embodiment of the handle, the elastic member is sleeved on the outside of the locking pin and accommodated on the inside of the guide sleeve. This arrangement allows the elastic member to compress and expand within the guide sleeve without interfering with other components in the mounting slot, thereby ensuring the operational stability of the locking assembly.

[0010] In a preferred embodiment of the aforementioned handle, the grip body further comprises a first conversion portion disposed within the mounting slot, the first conversion portion having a first inclined surface intersecting the predetermined direction; and the locking pin comprises a second conversion portion having a second inclined surface, the first inclined surface and the second inclined surface abutting against each other and being able to slide relative to each other. Through this arrangement, the first conversion portion and the second conversion portion can convert movement of the grip body in the predetermined direction into movement of the locking pin within the mounting slot, thereby achieving the effect of controlling the locking and unlocking of the locking assembly using the grip body.

[0011] In the preferred technical solution of the above-mentioned handle, the locking pin includes a protruding end that can extend out of the mounting slot, and the second conversion part is arranged on the side of the first conversion part opposite to the protruding end; the first conversion part includes a slide groove extending along the predetermined direction, the locking pin extends through the slide groove, and when the locking assembly switches between the locked state and the unlocked state, the locking pin can slide in the slide groove. Through the setting of the slide groove, while the locking pin follows the guide sleeve to move in the predetermined direction, the second conversion part on the locking pin abuts against the first conversion part, and the main body of the locking pin can extend through the slide groove and thus move freely in the predetermined direction. The second conversion part is arranged on the side of the slide groove opposite to the protruding end, so that the first conversion part limits the movement of the second conversion part to prevent the locking pin from detaching from the mounting slot under the force generated by the expansion of the elastic member.

[0012] In a preferred embodiment of the handle, the first end portion is provided with a first mounting slot, the second end portion is provided with a second mounting slot, the first mounting slot is provided with a first locking pin, and the second mounting slot is provided with a second locking pin. The handle body further includes a rope disposed therein, with both ends of the rope fixedly connected to the first locking pin and the second locking pin, respectively. The rope arrangement allows the handle body to move in a predetermined direction, causing the rope length to change, thereby pulling the first and second locking pins to retract them into the mounting slots, thereby improving the efficiency of the handle during board installation and removal.

[0013] To address the low installation and removal efficiency issues associated with conventional boards and chassis, the present invention further provides a board. The board includes a handle according to any of the aforementioned preferred technical solutions. The handle improves efficiency when installing or removing the board from the chassis.
