Description

Technical Field

[0001] This utility model relates to the field of multi-layer drawer equipment technology, and in particular to a multi-layer drawer opening and closing anti-foolproof mechanism. Background Technology

[0002] Most equipment on the market can pull out multiple drawers at the same time. However, when multiple drawers are pulled out at the same time, the center of gravity of the equipment shifts forward and it is easy to tip over, posing a safety hazard of injuring operators. This cannot meet the needs of enterprises for long-term processing and use.

[0003] In view of the above, it is necessary to improve the existing drawer opening and closing mechanism to adapt to the current needs of drawer opening and closing. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-layer drawer opening and closing anti-foolproof mechanism, including multiple sets of horizontally arranged drawer guide strips. The drawer guide strips are installed on the drawers and are pulled out horizontally with the drawers. Each set of drawer guide strips has a horizontally arranged mounting strip. The mounting strip is arranged in a downward slope shape near the pull-out side. The mounting strip has a groove on the slope side. A follow-up mechanism is provided above the mounting strip and a limiting mechanism is provided below it. Multiple sets of limiting mechanisms and follow-up mechanisms are fixedly installed on a linkage plate. The linkage plate is vertically arranged and has a mounting mechanism on one side. The mounting mechanism is fixedly installed inside the device. The linkage plate can be moved up and down and is installed on the mounting mechanism.

[0005] As a further supplement to this technical solution, the follower mechanism includes a cam fixing block and a cam bearing follower disposed on the cam fixing block. The cam fixing block is fixedly installed on the linkage plate, and the cam bearing can rotate above the mounting strip when the guide bar is pulled horizontally.

[0006] As a further supplement to this technical solution, the limiting mechanism includes a fixed block and a locking block disposed on the fixed block. The fixed block is fixedly installed on the linkage plate, and the locking block is fixedly installed on the fixed block. The upper end of the locking block is inclined upward to the left.

[0007] As a further supplement to this technical solution, the width of the card slot block is smaller than the width of the card groove.

[0008] As a further addition to this technical solution, the mounting strip is positioned at an angle to the lower right on one side of the slot.

[0009] As a further addition to this technical solution, the fixing block is L-shaped.

[0010] As a further supplement to this technical solution, the installation mechanism includes a fixed plate, a slide rail disposed on the fixed plate, and a slider disposed on the slide rail. The fixed plate is fixedly installed inside the equipment, the slide rail is fixedly installed on the fixed plate, and the slider is fixedly installed on the linkage plate on the side away from the follower mechanism and the limiting mechanism, and is slidably installed on the slide rail.

[0011] Its beneficial effect is that once any drawer is pulled out, the other drawers will be locked and cannot be pulled out, greatly reducing the risk of the equipment tipping over. It is easy to operate and has excellent performance. Attached Figure Description

Detailed Implementation

[0017] To facilitate a clearer understanding of this technical solution for those skilled in the art, the following will be described in conjunction with the appendix. Figure 1 -4. A detailed description of the technical solution of this utility model:

[0018] A multi-layer drawer opening and closing anti-foolproof mechanism includes multiple sets of horizontally arranged drawer guide bars 1. The drawer guide bars 1 are installed on the drawer and are pulled out horizontally with the drawer. Each set of drawer guide bars 1 has a horizontally arranged mounting strip 2. The mounting strip 2 is sloped downwards near the pull-out side. The mounting strip 2 has a groove 3 on one side of the slope. A follow-up mechanism 4 is provided above the mounting strip 2 and a limiting mechanism 5 is provided below it. Multiple sets of limiting mechanisms 5 and follow-up mechanisms 4 are fixedly installed on a linkage plate 7. The linkage plate 7 is vertically arranged and has a groove 3 on one side. There is an installation mechanism 6, which is fixedly installed inside the equipment. The linkage plate 7 can be moved up and down and installed on the installation mechanism 6. When working, when one drawer is pulled out, the follower mechanism 4 can move on the installation strip 2. Since one side of the installation strip 2 is set in a slope shape, the follower plate and its device will move upward as a whole during the pulling process, thereby causing the limiting mechanism 5 of other layers to be stuck in the slot 3, so that the drawers of other layers cannot be opened. Thus, when any drawer is pulled out, the other drawers will be locked and cannot be pulled out.

[0019] The structure of the follower mechanism 4 will be described in detail below. The follower mechanism 4 includes a cam fixing block 5141 and a cam bearing follower 42 set on the cam fixing block 5141. The cam fixing block 5141 is fixedly installed on the linkage plate 7. When the guide bar is pulled horizontally, the cam bearing can rotate above the mounting bar 2. When the drawer is pulled out, the drawer guide bar 1 moves with the drawer, which causes the cam bearing follower 42 to rotate on the mounting bar 2. Since one end of the mounting bar 2 is set in a slope shape, the linkage plate 7 connected to the cam fixing block 5141 moves upward as a whole, which causes the limiting mechanism 5 of other layers to be stuck in the slot 3, thus achieving locking.

[0020] The structure of the limiting mechanism 5 will be described in detail below. The limiting mechanism 5 includes a fixing block 51 and a locking block 52 disposed on the fixing block 51. The fixing block 51 is fixedly installed on the linkage plate 7, and the locking block 52 is fixedly installed on the fixing block 51. The upper end of the locking block 52 is inclined upward to the left. During operation, due to the up and down movement of the linkage plate 7, the locking block 52 can be received in the slot 3 or not in contact with the slot 3, thus completing the limiting function. The width of the locking block 52 is smaller than the width of the slot 3, which facilitates the installation of the locking block 52 in the slot 3, and the slot 3 can effectively limit it. The mounting strip 2 is located on one side of the slot 3 and is inclined downward to the right. When the drawer is closed, the locking block 52 moves under the mounting strip 2, which can play a certain buffering role. The fixing block 51 is L-shaped.

[0021] The structure of the installation mechanism 6 will be described in detail below. The installation mechanism 6 includes a fixed plate 61, a slide rail 62 set on the fixed plate 61, and a slider 63 set on the slide rail 62. The fixed plate 61 is fixedly installed inside the equipment, the slide rail 62 is fixedly installed on the fixed plate 61, and the slider 63 is fixedly installed on the linkage plate 7 away from the follower mechanism 4 and the limiting mechanism 5 and is slidably installed on the slide rail 62. When the linkage plate 7 moves up and down, the slider 63 can move stably up and down on the slide rail 62 to prevent displacement.

[0022] The overall working principle of this utility model will be explained in the following system: The drawer guide bar 1 is pulled out horizontally together with the drawer. The cam bearing follower 42 moves upward on the mounting bar 2 via the ramp on the mounting bar 1, thereby driving the cam fixing block 5141, the locking block 52 and the linkage plate 7 to move upward along the slide rail 62. The limiting mechanism 5 and the follower mechanism 4 of other layers also move upward. After the locking block 52 of other layers moves upward, it is inserted into the slot 3 of the mounting bar 2, and the other drawers are stuck and cannot be pulled out.

[0023] The above technical solution only embodies the preferred technical solution of this utility model. Any changes that may be made by those skilled in the art to certain parts of it embody the principle of this utility model and fall within the protection scope of this utility model.
