Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the utility model, fall within the scope of protection of the utility model.

As shown in fig. 1 and 2, the anti-toppling drawer cabinet comprises a cabinet body 1, at least two layers of drawers 2 are arranged in the cabinet body 1 in a drawable manner, an inlet and an outlet for drawing the drawers 2 are formed in the cabinet body 1, the inlet and the outlet are defined as the front, one side of the cabinet body 1 opposite to the inlet and the outlet is positioned as the rear, a connecting rod 3 which can be arranged in a sliding manner up and down is arranged on the inner side surface of a side plate of the cabinet body 1, the arrangement direction of the connecting rod 3 is perpendicular to the drawing direction of the drawers 2, and a slide way 4 is arranged on one side surface of each drawer 2 corresponding to the connecting rod 3 along the front-rear direction.

In this embodiment, the slide 4 is made of a plate structure, the plate structure is bent along the front-back direction, a vertical plane and a horizontal plane are formed after bending, the vertical plane is connected to the side surface of the drawer 2, the horizontal plane is used as a sliding track, the slide 4 sequentially includes an inclined section 4-1 and a horizontal section 4-2 along the front-back direction, that is, the horizontal plane of the slide 4 is divided into the inclined section 4-1 and the horizontal section 4-2 along the front-back direction, and the inclined section 4-1 and the horizontal section 4-2 are connected to each other.

In this embodiment, the inclined section 4-1 is disposed near the inlet and outlet of the cabinet 1, the horizontal section 4-2 is disposed near the rear of the cabinet 1, and a limiting member 5 is disposed on the side of the drawer 2 near the inclined section 4-1, wherein the end of the inclined section 4-1 facing forward is inclined downward with respect to the horizontal section 4-2, and correspondingly, the limiting member 5 is disposed above the inclined section 4-1 and spaced apart from a certain gap to form a gap for allowing the moving block 6 corresponding to the slide 4 to pass through. At this time, the connecting rod 3 is in its unlocked state at the lower end position of the up-and-down sliding stroke, and in its locked state at the upper end position of the up-and-down sliding stroke, and the connecting rod 3 is initially in its unlocked state at the lower end position under its own weight. Of course, an elastic restoring member may be further provided to ensure that the connecting rod 3 is in an unlocked state when no external force is applied, and the elastic restoring member may be a spring.

In other embodiments, the inclined section 4-1 may be disposed obliquely upward with respect to the horizontal section 4-2, and the displacement state of the open connecting rod 3 is opposite to that of the previous embodiment, that is, the upper end position of the vertical sliding stroke of the connecting rod is in the unlocked state, and the lower end position is in the locked state, and then an elastic reset member (such as a spring) needs to be disposed to be initially in the unlocked state at the upper end.

In this embodiment, as shown in fig. 3, the inclined section 4-1 is disposed obliquely downward, the limiting member 5 is disposed above the inclined section 4-1, the connecting rod 3 is provided with moving blocks 6 corresponding to each slide 4 one by one and capable of sliding on the respective slide 4, the limiting member 5 is provided with a first blocking wall 5-1 for preventing the moving blocks 6 from moving forward away from the slide 4, the drawer 2 is positioned in the cabinet 1 to be in an initial state, when in the initial state, the moving blocks 6 on the connecting rod 3 are disposed at the front end opening of the inclined section 4-1, when any drawer 2 is pulled, the slide 4 on the connecting rod 3 moves forward along with the drawer 2, the corresponding moving blocks 6 on the connecting rod 3 slide relatively with the slide 4, the moving blocks 6 slide backward from the end opening of the inclined section 4-1, and the moving blocks 6 simultaneously move upward along the inclined section 4-1, the moving blocks 6 drive the connecting rod 3 to move upward, and as the connecting rod 3 moves upward, when the connecting rod 3 is in the initial state, the other moving blocks 6 simultaneously move upward along the inclined section 4-1 and move vertically along the corresponding section 4-1, thus preventing the other moving blocks 5 from moving forward along the inclined section 4-1, the other side 5 is prevented from moving forward, and the other side 5 is prevented from moving forward, as shown in the vertical section 5 is pulled, and the other side 5 is prevented from moving forward, and the side 5 is prevented from moving vertically and the side 5 is pulled and the side opposite to move vertically and the side 5, thus, the movable block 6 is blocked in front of the first blocking wall 5-1, and the movable block 6 and the first blocking wall 5-1 can be prevented from being misplaced to cause locking failure; when the drawn drawer 2 is retracted into the cabinet 1, i.e., the drawer 2 is moved backward, the moving block 6 slides from the horizontal section 4-2 to the inclined section 4-1 and then slides from the rear to the front along the inclined section 4-1, i.e., the moving block 6 falls back down, and the moving block 6 is again in the initial state until any drawer 2 is drawn next time and the above sliding action is repeated.

In another embodiment, the inclined section 4-1 may be disposed obliquely upward, the limiting member 5 is located below the inclined section 4-1, and when any drawer 2 is pulled at this time, the moving block 6 drives the connecting rod 3 to move vertically downward along the inclined section 4-1, and as the connecting rod 3 descends, the remaining moving blocks 6 on the connecting rod 3 descend to the limiting member 5 below the corresponding inclined section 4-1, and at this time, each moving block 6 ascends to be just blocked in front of the corresponding first blocking wall 5-1, so as to prevent the limiting member 5 from sliding forward along with the drawer. It should be noted that, at this time, an elastic member needs to be added between the bottom of the connecting rod 3 and the cabinet body 1, and the connecting rod 3 is lifted to an initial position state by the elastic force of the elastic member, so that the connecting rod 3 can be continuously restored to the lifting position under the action of the spring, and the moving block 6 is blocked in front of the first blocking wall 5-1. Of course, in the embodiment in which the inclined section 4-1 is inclined downward, a spring for applying a downward force to the connecting rod 3 may be provided to increase the restoring force thereof, which can be regarded as a supplement to the gravity restoring of the above embodiment.

As shown in fig. 4 and 5, a sliding component 7 is arranged between the side surface of each drawer 2 and the inner side surface of the cabinet body 1, the sliding component 7 comprises a sliding rail 7-1, a guide rail 7-2 and a bracket 7-3, the sliding rail 7-1 is arranged on the side surface of the drawer 2, the bracket 7-3 is arranged on the inner side surface of the cabinet body 1, the guide rail 7-2 is arranged on the bracket 7-3, the guide rail 7-2 and the sliding rail 7-1 form sliding fit, the drawer 2 is pulled through the matching of the sliding rail 7-1 and the guide rail 7-2, each bracket 7-3 is provided with a through hole 7-4, the through holes 7-4 on the brackets 7-3 are positioned on the same straight line, and the connecting rod 3 is inserted into the through holes 7-4 and is in an active state, so that the connecting rod 3 can slide up and down along the through holes 7-4.

The end part of the horizontal section 4-2 far away from the inclined section 4-1 is connected with an arc-shaped guide section 4-3, when the drawer is pulled out to the limit position, the moving block 6 can only reach the upper end or the middle part of the downward slope section of the arc-shaped guide section 4-3, so that the other moving blocks 6 can be kept at the locking state position, and the hand part has a pause feel when the drawer 2 is pulled out, when the drawer 2 needs to be pushed to recover, the moving block 6 moves along the guide section 4-3, and rises to the position of the horizontal section 4-2 from the upper end or the middle part of the arc-shaped guide section 4-3, and at the moment, the arc-shaped guide section 4-3 plays a role of guiding the moving block 6 so as to facilitate pushing the drawer 2.

The moving block 6 has a cylindrical structure, when the moving block 6 and the slideway 4 slide relatively, the slideway 4 only contacts with the periphery of the cylinder, so that the contact area is reduced as much as possible, and the moving block 6 can be in other shapes such as a cuboid, a sphere or an ellipsoid. In addition, the moving block 6 can be rotatably connected to the connecting rod 3 to form a roller-like structure, so that labor is saved when the drawer is pulled or closed.

The included angle between the inclined section 4-1 and the horizontal section 4-2 is 150+/-15 degrees, so that the inclined section 4-1 can easily slide relative to the moving block 6, and a certain degree of setback can be maintained to obtain good pulling hand feeling.

The inclined section 4-1 and the horizontal section 4-2 are in smooth transition, so that the moving block 6 can be smoother when moving from the inclined section 4-1 to the horizontal section 4-2; wherein the inclined section 4-1 and the horizontal section 4-2 may be of a split structure and connected to each other or integrally formed.

During the drawer drawing, there is a risk that the moving block 6 will be separated from the slide 4 due to inertia when sliding upward along the inclined section 4-1, and therefore, a second blocking wall 5-2 is provided at a position above the stopper 5 corresponding to the moving block 6 to prevent the moving block 6 from being separated from the slide 4. The second blocking wall 5-2 is used for abutting against the moving block 6 at one end of the up-down sliding stroke of the connecting rod 3 (i.e. the up-down sliding stroke end corresponding to the locking state of the connecting rod 3) to limit the connecting rod 3.

As shown in fig. 6 and 7, the connecting rod 3 is provided with a limiting block 8, in this embodiment, the limiting block 8 is only one and is located at a position corresponding to the uppermost drawer 2, the limiting block 8 is located under the uppermost moving block 6, as shown in fig. 3 and 4, the limiting block 8 is supported by the guide rail 7-2 to limit the lowest stroke position of the connecting rod 3, the limiting block 8 is clamped on the surface of the guide rail 7-2, the connecting rod 3 is limited on the guide rail 7-2, and a limit on the descending path is formed for the connecting rod 3, because the inclined section 4-1 in this embodiment is arranged in a downward inclined manner, during the drawing and pushing processes of the drawer 2, the connecting rod 3 continuously slides up and down, when the connecting rod 3 slides down to the limit position, the limiting block 8 abuts against the guide rail 7-2 to prevent the connecting rod 3 from continuing to slide down and separating from the limit position, so that the other end of the upper and lower sliding stroke of the connecting rod 3 (i.e. the upper and lower sliding stroke end corresponding to the unlocking state of the connecting rod 3) abuts against the guide rail 7-2 via the limiting block 8.

Of course, the bottom of the connecting rod 3 can be bottomed to the bottom surface of the cabinet body 1, but the connecting rod 3 can collide with the bottom surface of the cabinet body 1 after sliding downwards each time, so that noise is generated, and the connecting rod 3 is easy to deform.
