Description

Technical Field

[0001] This utility model relates to the technical field of storage cabinets, and in particular to a storage board lifting mechanism and cabinet body. Background Technology

[0002] Currently, most cabinets on the market have fixed internal dividers, meaning the volume of multiple storage spaces cannot be changed. This results in items of different heights not being able to fit into some spaces, or some higher spaces being difficult to place items in. To address this issue, existing technology has designed height-adjustable shelves within cabinets. However, these height-adjustable shelf designs on the market have the following problems:

[0003] 1. The shelf is driven by a motor and lead screw, which requires electricity and poses a safety hazard.

[0004] 2. The screw is driven by a motor, which has a complex structure, low lifting efficiency, high noise, and high cost. Utility Model Content

[0005] In view of the above-mentioned problems of existing storage lifting structures, the present invention aims to provide a storage board lifting mechanism and cabinet that can be quickly triggered to lift the storage board to different heights. It has a simple structure, high efficiency, low noise and low cost, and does not require electricity, thus eliminating safety hazards.

[0006] The specific technical solution is as follows:

[0007] A shelf lifting mechanism, comprising:

[0008] At least one telescopic mechanism, which is arranged longitudinally;

[0009] A shelf is horizontally installed on top of the telescopic mechanism;

[0010] Both the linkage mechanism and the operating component are located at the bottom of the shelf. One end of the linkage mechanism is rotatably connected to the operating component. When the operating component is moved down or up, the other end of the linkage mechanism is used to trigger the telescopic mechanism so that the shelf can be raised or lowered to different heights.

[0011] In the above-mentioned shelf lifting mechanism, the telescopic mechanism is a gas spring, and the linkage mechanism compresses the piston rod of the gas spring to raise or lower the shelf to different heights.

[0012] The aforementioned shelf lifting mechanism, wherein the linkage mechanism includes at least one linkage assembly and a trigger assembly, wherein the operating member, the linkage assembly and the trigger assembly are sequentially connected in a transmission manner, so that the trigger assembly triggers the telescopic mechanism.

[0013] In the aforementioned shelf lifting mechanism, the middle part of the operating member is directly or indirectly hinged to the bottom of the shelf, the first end of the operating member is the driving end, and the second end of the operating member is hinged to the linkage assembly. Moving the operating member downward or upward causes the linkage assembly to move horizontally, thereby driving the trigger assembly to rotate and press the trigger point of the telescopic mechanism.

[0014] In the aforementioned shelf lifting mechanism, the triggering component includes a transmission rod and at least one pressing member. The pressing member is mounted on the transmission rod and located directly above the telescopic mechanism. The linkage assembly drives the transmission rod to rotate so that the pressing member presses against the trigger point of the telescopic mechanism.

[0015] In the aforementioned shelf lifting mechanism, the linkage assembly includes a first linkage and a second linkage that are hinged to each other. The first linkage is hinged to the second end of the operating member, and the second linkage is mounted on the transmission rod.

[0016] In the aforementioned shelf lifting mechanism, the operating components include a transmission plate and an operating lever. The operating lever is mounted on the first end of the transmission plate, the middle part of the transmission plate is directly or indirectly hinged to the bottom of the shelf, and the second end of the transmission plate is hinged to the connecting assembly.

[0017] The aforementioned shelf lifting mechanism includes two telescopic mechanisms, and the triggering component includes two pressing members. The two pressing members correspond to and cooperate with the two telescopic mechanisms respectively, so that the two telescopic mechanisms simultaneously drive the shelf to lift to different heights.

[0018] In the aforementioned shelf lifting mechanism, the bottom of the shelf is provided with a first mounting frame and a second mounting frame, the middle part of the operating component is hinged to the first mounting frame, and the transmission rod is rotatably connected to the second mounting frame.

[0019] A cabinet, comprising a shelf lifting mechanism as described in any one of the above, wherein the shelf moves longitudinally within the cabinet and a hanging bracket is installed at the bottom of the shelf.

[0020] The positive effects of the above technical solution compared with the existing technology are:

[0021] This invention can quickly trigger the telescopic mechanism to raise and lower the shelf to different heights. It has a simple structure, high efficiency, low noise and low cost, and does not require electricity, so there are no safety hazards. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0031] like Figures 1 to 5 As shown, a preferred embodiment of a shelf lifting mechanism is illustrated, comprising: at least one telescopic mechanism 1, a shelf 2, a linkage mechanism, and an operating member 3. The telescopic mechanism 1 is arranged longitudinally, and the shelf 2 is horizontally installed on the top of the telescopic mechanism 1. The linkage mechanism and the operating member 3 are both arranged at the bottom of the shelf 2. One end of the linkage mechanism 2 is rotatably connected to the operating member 3. When the operating member 3 is moved downward or upward, the other end of the linkage mechanism 2 is used to trigger the telescopic mechanism 1 to raise or lower the shelf 2 to different heights.

[0032] Furthermore, as a preferred embodiment, the telescopic mechanism 1 is a gas spring, and the linkage mechanism compresses the piston rod of the gas spring to raise and lower the shelf 2 to different heights.

[0033] When the linkage mechanism squeezes the end of the piston rod of the gas spring, it triggers the internal valve of the gas spring to unlock. The high-pressure gas expands and pushes the piston rod of the gas spring to extend automatically. When squeezed, the valve of the gas spring is switched on and off, which can raise the shelf 2 to the set height.

[0034] Manually pull down the operating component 3 to apply a reverse force through the linkage mechanism, overcoming the air pressure of the gas spring and pressing the piston rod of the gas spring back into its cylinder, which can lower the shelf 2 to the set height.

[0035] This utility model can quickly trigger the telescopic mechanism 1, so that the shelf 2 can be raised and lowered to different heights. It has a simple structure, high efficiency, low noise and low cost, and does not require electricity, so there are no safety hazards.
