Description

Technical Field

[0001] This utility model relates to the field of connecting card technology, specifically an expansion connecting card. Background Technology

[0002] As the name suggests, a connector is a type of connector used to connect two components. It allows for the quick connection and fixation of two sets of components, increasing the stability between them and facilitating the connection and fixation of the components.

[0003] To ensure connection stability, most existing connectors have screw holes drilled in them before screws are used for fixing. While this increases overall stability, it makes it inconvenient to quickly connect and fix the connectors. Each time they are used, tools are needed to tighten the screws, making the whole process very cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide an expansion connector to solve the problem mentioned in the background art that the connectors currently in use are inconvenient for users to quickly connect and fix.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an expansion connecting clip, comprising: a movable seat and a connecting block, wherein the movable block is mounted on the top of the movable seat, a rotating block is connected through the middle of the movable block, and the connecting block is connected to one side of the rotating block through the through groove of the movable block.

[0006] A cylindrical block is mounted on the top of the rotating block, and a barbed fixing buckle is provided on the top of the cylindrical block. A connector is provided on the top of the movable block.

[0007] Preferably, a movable spring is installed inside the connecting block via a groove, and a pull block that passes through the connecting block is connected to one side of the movable spring.

[0008] Preferably, a telescopic column is connected to one side of the pull block.

[0009] Preferably, a fixing block is connected between the telescopic column and the inner wall of the connecting block through groove.

[0010] Preferably, two sets of telescopic columns are symmetrically installed about the center line of the connecting block, and the telescopic columns form a telescopic structure with the connecting block through the pull block.

[0011] Preferably, the rotating block and the connecting block are an integrated structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this expansion connecting clip, the connecting piece can be sleeved on the outside of the movable block. Then, the telescopic column can be pulled into the inside of the connecting block by the pull block. Without the obstruction of the telescopic column and the fixed block, the connecting block can be pulled, causing the connecting block to drive the rotating block inside the movable block to rotate. When the rotating block rotates, it will synchronously drive the top cylindrical block to rotate, causing the two sides of the cylindrical block to press the bottom sides of the barbed fixing buckle outward. This allows the connecting piece to be limited and fixed on the outside of the movable block by the barbed fixing buckle, thus facilitating the fixed connection of the connecting piece. Then, when the pull block is released, the return action of the movable spring will cause the telescopic column and the fixed block to limit and fix the connecting block, thus ensuring that the cylindrical block always presses against the barbed fixing buckle, preventing the barbed fixing buckle from loosening. This is the characteristic of the use of this expansion connecting clip. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 and Figure 2 This utility model provides a technical solution: an expansion connecting clip, including: a movable seat 1 and a connecting block 4, a movable block 2 is installed on the top of the movable seat 1, a rotating block 3 is connected through the middle of the movable block 2, and the connecting block 4 is connected to one side of the rotating block 3 through the through groove of the movable block 2.

[0023] A cylindrical block 5 is installed on the top of the rotating block 3. A barbed fixing buckle 6 is provided on the top of the cylindrical block 5. A connector 7 is provided on the top of the movable block 2. A movable spring 8 is installed inside the connecting block 4 through a groove. A pull block 9 that passes through the connecting block 4 is connected to one side of the movable spring 8. A telescopic column 10 is connected to one side of the pull block 9. A fixing block 11 is connected between the telescopic column 10 and the inner wall of the through groove of the connecting block 4. Two sets of telescopic columns 10 are symmetrically installed about the center line of the connecting block 4. The telescopic column 10 forms a telescopic structure with the connecting block 4 through the pull block 9. The rotating block 3 and the connecting block 4 are an integrated structure. The rotating block 3 is rotatably set inside the movable block 2.

[0024] In practical implementation, the expansion connecting clip can pull the pull block 9, causing the two sets of pull blocks 9 to move closer to each other. The movement of the pull block 9 will cause the telescopic columns 10 on both sides of the connecting block 4 to retract into the connecting block 4, and at the same time, it will squeeze the movable spring 8 in the connecting block 4. When the telescopic column 10 retracts into the connecting block 4, the connecting block 4 is no longer limited by the telescopic column 10 and the fixed block 11, and then the connecting block 4 can be pulled. Since the rotating block 3 is set on the inner wall of the movable block 2, and the connecting block 4 passes through the through groove of the movable block 2 and is connected to the rotating block 3, when the connecting block 4 is pulled, the rotating block 3 is squeezed by the inner wall of the movable block 2 and guided by the connecting block 4. The rotating block 3 can only rotate through the center point.

[0025] When the rotating block 3 rotates, it will synchronously drive the top cylindrical block 5 to rotate. When the cylindrical block 5 rotates, it will squeeze one end of the barbed fixing buckle 6 through both sides, thereby squeezing both sides of the barbed fixing buckle 6 to the outside of the movable block 2. When the connector 7 is fitted onto the outside of the movable block 2, it is limited by the two sides of the bottom of the barbed fixing buckle 6, so that the connector 7 can be quickly fixed on the outside of the movable block 2, thus facilitating the connection and fixation of the connector 7.

[0026] Then you can release the pull block 9. At this time, the movable spring 8 will push the telescopic column 10 to reset through the pull block 9, so that the telescopic column 10 is stuck between the two sets of fixed blocks 11 inside the through groove of the movable block 2. Due to the limiting effect of the fixed blocks 11 on the telescopic column 10, the connecting block 4 cannot move up and down, so the connecting block 4 cannot pull the rotating block 3 to rotate. At the same time, the bottom of the barbed fixing buckle 6 is always in the open state to avoid loosening.

[0027] See Figures 1-7 It can be seen that when in use, the pull block 9 can be pulled, so that the pull block 9 drives the telescopic column 10 to retract into the connecting block 4. Then, the connecting block 4 pulls the rotating block 3 to rotate, and the cylindrical block 5 at the top of the rotating block 3 squeezes the barbed fixing buckle 6. The connecting piece 7 can be limited and fixed on the outside of the movable block 2 by the barbed fixing buckle 6.

[0028] In summary: When using this expansion connector, the connector 7 can be fitted onto the outside of the movable block 2. Then, by pulling the pull block 9, the telescopic column 10 will retract into the inside of the connector 4. At this time, pulling the connector 4 will cause the rotating block 3 to rotate. The rotation of the rotating block 3 will cooperate with the barbed fixing buckle 6 to limit the connector 7 to the outside of the movable block 2, thereby facilitating and quickly connecting and fixing the connector 7. This is the characteristic of the expansion connector. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0029] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
