Description

Technical Field

[0001] The utility model relates to the field of mechanical manufacturing, and particularly to a pull-ring handle with an improved structure. Background Technique

[0002] Pull-ring handles can also be seen in our daily life. Many doors or drawers are equipped with them. However, these pull-ring handles are relatively large in size, so a relatively wide space is required during use, resulting in the inconvenience of applying this type of pull-ring handle to devices such as small server drawer chassis, making the application range of the pull-ring handle not extensive enough.

[0003] The applicant has applied for a utility model patent in 2022, a pull-ring handle, with the patent number 202221896164.3.

[0004] To solve the above problems, the applicant hereby proposes a pull-ring handle with an improved structure, which occupies less space, is more lightweight in structure, and is more convenient to use. Summary of the Invention

[0005] The purpose of the utility model is to provide a pull-ring handle with an improved structure to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A pull-ring handle with an improved structure includes a bottom plate. A panel is provided at the top end of the bottom plate. Moving grooves are respectively opened on both sides of the inner wall of the bottom plate. Connecting blocks are slidably arranged inside the two moving grooves. One end of each side of the two connecting blocks is fixedly connected with a connecting rod. One end of the two connecting rods away from the connecting blocks is fixedly connected with an auxiliary pull-ring. One end of each side of the two connecting blocks away from the second through groove is fixedly connected with a convex block. Telescopic springs are fixedly arranged on the surfaces of the two convex blocks. One end of each of the two telescopic springs away from the convex block is fixedly connected with one end of the inner side of the two moving grooves respectively. Moving blocks are fixedly arranged on the opposite sides of the two connecting blocks. A rotating groove is opened on one side of the inner wall of the bottom plate close to the moving groove. A rotating shaft is rotatably arranged inside the rotating groove. A buckle is fixedly connected to one side of the rotating shaft. A reset spring is fixedly connected to the bottom of the buckle. The bottom end of the reset spring is fixedly connected with the bottom plate.

[0007] By pulling the auxiliary pull ring, the two connecting rods and the two connecting blocks are driven to move, thereby driving the two moving blocks to move along the two inclined grooves, further squeezing the buckle downward, causing the buckle to flip downward with the rotation axis as the center, unlocking the pull ring handle. At the same time, the return spring is compressed by the buckle, and the two telescopic springs are compressed by the two connecting blocks. Then, the auxiliary pull ring is released, causing the two connecting blocks to reset under the action of the two telescopic springs, further driving the two moving blocks to reset and no longer squeezing the buckle. At the same time, the buckle resets under the action of the return spring, causing the protruding part of the buckle to protrude, making the pull ring handle in a locked state.

[0008] Preferably, inclined grooves are provided on both sides of the top end of the buckle, and the two inclined grooves are respectively arranged corresponding to the two moving blocks. By moving the two moving blocks along the two inclined grooves, the buckle is squeezed downward.

[0009] Preferably, a plurality of limiting members are fixedly arranged at the top of the inner wall of the bottom plate on the side far from the rotation axis, and the plurality of limiting members are respectively arranged corresponding to the auxiliary pull ring. The arrangement of the plurality of limiting members facilitates the limitation of the auxiliary pull ring.

[0010] Preferably, two positioning columns are fixedly arranged on one side of the top end of the bottom plate, and two positioning holes are provided on one side of the top end of the bottom plate. The two positioning holes are respectively engaged with the two positioning columns. The cooperation of the two positioning holes and the two positioning columns facilitates the preliminary connection of the bottom plate and the panel.

[0011] Preferably, two fixing bolts are threadedly arranged on both sides of the connection between the bottom plate and the panel, and mounting holes are provided at three corners of the connection between the bottom plate and the panel. The arrangement of the four fixing bolts facilitates the further fixation of the bottom plate and the panel.

[0012] Preferably, a first through groove is provided in the middle of the top end of the panel, and the first through groove is arranged corresponding to the buckle. The arrangement of the first through groove facilitates the movement of the buckle.

[0013] Preferably, a second through groove is provided in the middle of the bottom end of the bottom plate, and the second through groove is arranged corresponding to the buckle. The arrangement of the second through groove facilitates the movement of the buckle.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] By pulling the auxiliary pull ring, two connecting rods and two connecting blocks are driven to move, thereby driving two moving blocks to move along two inclined grooves, and then squeezing the buckle downward, causing the buckle to flip downward with the rotation axis as the center, unlocking the pull ring handle. At the same time, the return spring is compressed by the buckle, and two telescopic springs are compressed by two connecting blocks. Then, release the auxiliary pull ring, so that the two connecting blocks reset under the action of the two telescopic springs, thereby driving the two moving blocks to reset and no longer squeezing the buckle. At the same time, the buckle resets under the action of the return spring, causing the protruding part of the buckle to protrude, making the pull ring handle in a locked state.

[0016] The utility model is used for the drawer of a small server chassis, with a lighter structure and more convenient use. Brief Description of the Drawings
