Description

Technical Field

[0001] The utility model belongs to the technical field of electronic equipment auxiliary tools, and in particular relates to a rotating shaft type auxiliary pulling and locking integrated mechanism. Background Art

[0002] Communication equipment is increasingly developing towards large capacity and high density, especially for plug-in core high-end rack equipment. The number of connectors on the board is increasing, and the pins of each connector are becoming denser and denser. As a result, the force required to plug and unplug the board is increasing; at the same time, the reliability requirements are also increasing. As a key mechanism for plugging and unplugging boards or modules, the puller needs to meet the structural strength, reliability and ease of operation under heavy load.

[0003] The prior art Chinese patent number is: CN201720819572.1, which is a rotary board and card puller, including an opening block that cooperates with the board and card handle, the opening block is connected to the rotating block, and after the rotating block rotates, it forms a holding force for clamping the board and card handle together with the opening block, and the opening block is connected to the prying handle through a rotating shaft. The rotating block is provided with a limiting mechanism to ensure that the board and card handle will not be damaged when the rotating block rotates and forms a holding force for clamping the board and card handle together with the opening block. It can be seen that this patented technology can indeed assist in removing the board and card from the slot, but manual installation is still required when inserting the board and card.

[0004] In addition, most of the existing boards on the market use CPCI or VPX standard pullers to install and fix the boards inside the chassis, and the chassis of non-standard board products are not compatible with the installation of universal pullers. Therefore, a board pull-out locking mechanism that can install and pull out boards and can adapt to a variety of chassis is needed. Utility Model Content

[0005] The purpose of the utility model is to provide a rotating shaft type pulling-assisting and locking integrated mechanism to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rotating shaft type auxiliary pulling and locking integrated mechanism, comprising:

[0007] A handle, and a handle seat that cooperates with the handle to complete the auxiliary pulling and locking;

[0008] The handle is connected to the handle seat through a spring shaft pin, a locking end is arranged on the handle near the spring shaft pin, and a board guide groove for facilitating board installation is arranged on the lower end of the handle seat near the spring shaft pin.

[0009] Preferably, a card slot is provided on the side of the handle base that contacts the board.

[0010] Preferably, the handle and the handle seat are arranged in an arc shape near the spring shaft pin.

[0011] Preferably, the handle is provided with a ring buckle for facilitating the exertion of force by fingers.

[0012] Preferably, the handle and the handle seat are made of high-strength alloy material.

[0013] Technical effects and advantages of the utility model:

[0014] This kind of rotating shaft type assisted extraction and locking integrated mechanism benefits from the setting of the handle, handle seat, spring shaft pin and locking end. When installing the board and card, the handle is pulled by the hand, and the board and card is subjected to gravity in the opposite direction of the handle pulling force, so that the spring shaft pin is stretched open, the handle is in an open state, and the board and card enters the installation position along the board and card guide groove track. After the board and card are installed, the handle is released, and the torsional force of the spring shaft pin disappears. At this time, the handle is closed, and the locking end of the handle is turned into the chassis locking groove to fix the board and card. The handle is twisted, and the spring shaft pin is stretched open by the tension, and the locking end of the handle is separated from the chassis locking groove. At this time, the board and card loses its fixation, and the assisted extraction function of the board and card is realized. This rotating shaft type assisted extraction and locking integrated mechanism has a simple structure and is easy to carry. It can complete the two functions of assisted extraction and locking of the board and card. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0019] The utility model provides Figure 1 A rotating shaft type pulling-assisting locking integrated mechanism device is shown.

[0020] The handle 1 is connected to the handle seat 3 through a spring shaft pin 5. A card slot 6 is provided on the side of the handle seat 3 that contacts the card 2 to prevent the card 2 from being offset when it is installed. A locking end 7 is provided near the spring shaft pin 5 at the handle 1, and a card guide slot 4 is provided near the spring shaft pin 5 at the lower end of the handle seat 3 to facilitate the installation of the card 2. The card 2 is subjected to gravity in the opposite direction of the pulling force of the handle 1, so that the spring shaft pin 5 is stretched open, and the card 2 enters the installation position along the track of the card guide slot 4. At this time, the locking end 7 is turned into the chassis locking slot 8 to fix the card 2.

[0021] The handle 1 is twisted, the spring shaft pin 5 is stretched open by the tension, and the locking end 7 is separated from the chassis locking groove 8. At this time, the board 2 loses its fixation, and the auxiliary extraction function of the board 2 is realized.

[0022] Working principle:

[0023] When installing the board 2, the handle 1 is pulled by the hand, and the board 2 is subjected to gravity in the opposite direction of the pulling force of the handle 1, so that the spring shaft pin 5 is stretched open, the handle 1 is in an open state, and the board 2 enters the installation position along the board guide groove 4 track. After the board 2 is installed, the handle 1 is released, and the torsional force of the spring shaft pin 5 disappears. At this time, the handle 1 is closed, and the locking end 7 is rotated into the chassis locking groove 8 to fix the board 2. The handle 1 is twisted, and the spring shaft pin 5 is stretched open by the pulling force, and the locking end 7 is separated from the chassis locking groove 8. At this time, the board 2 loses its fixation, and the assisted pulling function of the board 2 is realized. The rotating shaft type assisted pulling and locking integrated mechanism has a simple structure, is easy to carry, and can complete the two functions of assisted pulling and locking of the board.

[0024] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited to it. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the utility model according to the technical scheme and utility model concept of the utility model, which should be covered by the protection scope of the utility model.
