Detailed Description

The technical solution of the present invention will be further described in detail with reference to the accompanying drawings.

The first embodiment is as follows: as shown in fig. 1-2, the utility model comprises a slide rail 4 arranged between a drawer 1 and a box body 2, and a shaking-proof frame 3 which can stretch back and forth, wherein the shaking-proof frame 3 is arranged between the box body 2 and the drawer 1, and the shaking-proof frame 3 moves forward along with the drawer 1 in the sliding process before the drawer 1 to pull the drawer 1. In the process of pulling the drawer 1 to move forwards, the anti-shaking frame 3 moves forwards along with the drawer, the anti-shaking frame 3 pulls the drawer 1, and the drawer 1 is limited by the anti-shaking frame 3, so that the drawer 1 can stably move forwards along the sliding rail 4, and the shaking generated in the process of moving the drawer 1 forwards and backwards is reduced.

For further improving the stability that drawer 1 removed, prevent shaking frame 3 and including controlling two sets of drive mechanism that set up side by side, drive mechanism passes through coupling assembling and links to each other with box 2, drawer 1. Establish two sets of drive mechanism for drawer 1 left and right sides atress is even, and further reduction rocks, and the inconsistent condition of displacement of the left and right sides of drawer 1 can effectively be avoided appearing to two sets of drive mechanism that the while is the same, guarantees that drawer 1 can sharp antedisplacement or retreat.

In this technical scheme, two sets of traction mechanisms each include a first swing arm 301 and a second swing arm 302, and the first swing arm 301 and the second swing arm 302 are rotatably connected through a rotating shaft. When the drawer 1 moves forward, the included angle between the first swing arm 301 and the second swing arm 302 increases from small to large, so that the traction mechanism extends forward to move forward along with the drawer 1.

In order to prevent jamming, the traction mechanism further comprises a linkage rod 303 for connecting the two groups of traction mechanisms; the linkage rod 303 is rotatably connected with the rotating shaft, and the first swing arm 301 and the second swing arm 302 can relatively rotate relative to the linkage rod 303. The linkage rod 303 is arranged, so that the stability of the structure is improved, the rigidity is improved, the synchronism of actions is increased, the positions of the two groups of traction mechanisms advancing forwards are consistent, the two traction mechanisms move forwards integrally, the phenomenon that the left side or the right side deviates due to the gap of the sliding rail 4 is prevented, the sliding smoothness is improved, and the drawer 1 is prevented from being blocked.

In order to increase the application range and avoid forming dead angles, the sum of the lengths of the first swing arm 301 and the second swing arm 302 is greater than the stroke length of the slide rail 4. So that the sliding movement leaves a margin to adapt to the drawers 1 with various lengths and widths, and the dead angle formed by the 180-degree included angle formed after the first swing arm 301 and the second swing arm 302 are extended is avoided.

For making things convenient for the dismouting, coupling assembling includes first coupling assembling, second coupling assembling, and first swing arm 301 links to each other with the box back plate through first coupling assembling, and second swing arm 302 passes through second connecting piece 305 and links to each other with drawer 1 bottom plate. The connecting assembly enables the traction mechanism to be a detachable structure and can be separated from the drawer 1 and the box body 2; the connecting component comprises screws, bolts or rivets and the like.

To improve the reliability of operation. The first connecting assembly comprises a first connecting piece 304 and a first fixing piece for fixing the first connecting piece 304 on the rear plate of the box body; the first connecting piece 304 is rotatably connected with the first swing arm 301 through a pin. The first connecting piece 304 can be fixed on the rear plate of the box body by a plurality of first fixing pieces in a connecting mode, and the connecting mode increases the connecting strength and improves the working reliability.

As shown in fig. 4, to improve the connection strength: the first connecting member 304 is formed by stamping a metal plate, and is provided with a first swing arm connecting portion 30401 and a box body rear plate connecting portion 30402; the box body rear plate connecting portion 30402 is attached to the box body rear plate by a first fixing member, and the first swing arm connecting portion 30401 is vertically connected to the box body rear plate connecting portion 30402. The first connecting member 304 is formed by stamping a metal plate, so that the structure is simple, and the integral structure is beneficial to improving the connecting strength.

The second connecting assembly comprises a second connecting piece 305 and a second fixing piece for fixing the second connecting piece 305 on the bottom plate of the drawer 1; the second connecting member 305 is rotatably connected to the second swing arm 302 by a pin. The pin and the second connecting member 305 are integrated or separated.

In order to facilitate the assembly and avoid the interference of the connecting components, such as the collision between the first fixing component and the second fixing component, in this embodiment, the second connecting component 305 is disposed on the bottom plate of the drawer 1, rather than on the rear side plate of the drawer 1, and the second connecting component 305 disposed in front can avoid the collision with the first connecting component 304 disposed on the rear plate of the box body; the second connecting piece 305 is arranged on the top surface of the bottom plate of the drawer 1. As shown in fig. 5, a hollow tapered connecting portion 30501 which is convex downward and has a large top and a small bottom is disposed in the middle of the second connecting member 305, fixing holes are disposed on the second connecting member 305 at two sides of the connecting portion, the tapered connecting portion 30501 penetrates through the bottom plate of the drawer 1 from top to bottom, and the second fixing member penetrates through the second swing arm 302 from bottom to top to be connected with the tapered connecting portion 30501. The lower surface of second connecting piece 305 offsets with the upper surface of drawer 1 bottom plate, and the contact surface is big, and big-end-up is little about the toper connecting portion 30501 in the second connecting piece 305, is conveniently wearing to establish drawer 1 bottom plate, when easy to assemble, because its junction area with second connecting piece 305 main part is big, also is favorable to gaining in strength. Contributing to an increase in the working life. In the embodiment, when the drawer 1 is closed, the angle α between the first swing arm 301 and the second swing arm 302 is between 4 and 7 degrees, and as shown in fig. 3, the angle between the first swing arm 301 and the second swing arm 302 is 5.5 degrees; if the angle is too small, a collision may occur, and if the angle is too large, the maximum stroke may be affected, and in order to ensure the maximum stroke, the lengths of the first swing arm 301 and the second swing arm 302 need to be increased, and the force bearing capacities of the first swing arm 301 and the second swing arm need to be correspondingly increased, which may cause a situation such as cost increase.

Example two: the same parts as those in the first embodiment are not described again, but the differences are as follows:

in this embodiment, the first swing arm 301 and the second swing arm 302 are connected in a sliding manner, and the second swing arm 302 can move back and forth on the first swing arm 301; the linkage rod is fixedly connected between the two second swing arms 302.

The above-mentioned drawer sliding device with shaking prevention frame shown in fig. 1-6 is a specific embodiment of the present invention, and it has embodied the substantial features and progress of the present invention, and can be modified according to the actual use requirement, and the equivalent modifications of the shape, structure, etc. are all within the protection scope of the present solution.
