DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example: See Figures 1 to 5 According to an embodiment of the utility model, a technical solution is provided: a lifting cabinet comprises a back panel 1 and a cabinet body 2, the back panel 1 is slidably connected to the back panel 1 through a first slide rail 3 along a first direction parallel to the front face of the back panel 1, the front face of the back panel 1 is the side of the back panel 1 facing away from the wall when the back panel 1 is installed, and is also understood as the side of the cabinet body 2 installed on the back panel 1, the first direction can be understood as the direction perpendicular to the ground after the back panel 1 is installed, a locking mechanism is arranged between the first slide rail 3 and the cabinet body 2, and the locking mechanism comprises a first handle 4, a second handle 5, a compression spring The cabinet body 2 comprises a first handle 4 and a second handle 5, wherein the first handle 4 is fixed to the bottom of the cabinet body 2, the second handle 5 is elastically connected to the bottom of the first handle 4 through a compression spring 6, the locking rod 7 is slidably connected to the cabinet body 2 along a second direction perpendicular to the first direction through a second slide rail 8, a side of the first slide rail 3 facing the locking rod 7 is provided with a plurality of latch teeth 9 distributed at intervals along the first direction, a connecting column 11 is provided at one end of the locking rod 7 close to the first handle 4, and a strip-shaped inclined hole 10 is provided on the second handle 5, the connecting column 11 is connected to the inclined hole 10 and can slide along the inclined hole 10.

[0028] With the lifting cabinet adopting the above structure, when it is necessary to move the cabinet body 2, one only needs to pinch the first handle 4 and the second handle 5 to disengage the locking rod 7 from the latch tooth 9, and the cabinet body 2 can move along the first direction (i.e., the direction perpendicular to the ground). When it moves to the appropriate position, the two handles can be released and the height of the cabinet body 2 can be locked by utilizing the abutment between the locking rod 7 and the latch tooth 9. This purely mechanical manual lifting method has a low failure rate, and the height of the cabinet body 2 after lifting is easy to fix, and has the advantages of simple structure and easy operation.

[0029] In this embodiment, two first slide rails 3 are provided, the two first slide rails 3 are parallel to each other and arranged at intervals along the second direction, the locking mechanism includes two locking rods 7, the two locking rods 7 are respectively provided on both sides of the first handle 4 along the second direction, and the two first slide rails 3 are provided with latch teeth 9. Through the design of the double slide rails, the stability of the cabinet 2 sliding on the back plate 1 along the first direction can be improved, and through the design of the double locking rods 7, the position locking of the cabinet 2 in the first direction can be made more stable.

[0030] In this embodiment, the cross-sections of the two first slide rails 3 are both convex, and the back of the cabinet 2 is provided with a slide groove 19 that slidably cooperates with the first slide rail 3. Of course, as long as the cabinet 2 can be slidably connected to the back panel 1 along the first direction, there is no particular limitation on the specific form of the first slide rail 3.

[0031] In this embodiment, the latching teeth 9 are wedge-shaped, the top of the latching teeth 9 is a plane parallel to the second direction, and the end of the locking rod 7 facing the first slide rail 3 has an upwardly disposed inclined surface 12. When the cabinet 2 is locked, the locking rod 7 abuts against the plane of the latching teeth 9, which can effectively fix the height of the cabinet 2. When the cabinet 2 needs to be moved upward, the latching teeth 9 can push the locking rod 7 toward the direction of the first handle 4 through the inclined surface 12, so that the cabinet 2 can be moved upward without pinching the first handle 4 and the second handle 5, making the upward movement of the cabinet 2 more convenient.

[0032] In this embodiment, an elastic force recovery device is provided between the cabinet 2 and the back plate 1, and the elastic force recovery device includes a fixing column 13 located above the cabinet 2 and fixed to the back plate 1, and a spring 14 wound around the outside of the fixing column 13, one end of the spring 14 is fixed to the fixing column 13, and the other end is fixed to the cabinet 2, and the elastic force recovery device also includes a cover 15, which is covered on the spring 14 and fixed to the back plate 1 by screws 16, and an outlet 17 is provided at the bottom of the cover 15, and the spring 14 extends from the outlet 17. When the cabinet 2 is moved upward, the spring 14 can provide a certain resilience for the upward movement of the cabinet 2, making the upward movement of the cabinet 2 more labor-saving.

[0033] In this embodiment, a positioning roller 18 is provided in the cover body 15 near the outlet 17, the positioning roller 18 is rotatably connected to the back plate 1, and the spring 14 is wound around the positioning roller 18. By providing the positioning roller 18, the portion of the spring 14 extending from the outlet 17 of the cover body 15 can be oriented, so as to avoid the spring 14 from scratching the outlet 17 of the cover body 15, thereby extending the service life of the spring 14.

[0034] Working principle: First, the back panel 1 of the lifting cabinet is fixed to the wall of the kitchen by bolts or other fasteners. When the cabinet body 2 needs to be moved, the user only needs to pinch the first handle 4 and the second handle 5 to compress the compression spring 6 and the locking rod 7 disengages from the latch tooth 9. At this time, the cabinet body 2 can move along the first direction (i.e., the direction perpendicular to the ground). When it moves to the appropriate position, the first handle 4 and the second handle 5 are released. The second handle 5 moves away from the first handle 4 under the rebound force of the compression spring 6, and the second handle 5 drives the locking rod 7 to move in the direction close to the latch tooth 9. Finally, the locking rod 7 is pressed against the top of the latch tooth 9, thereby locking the height of the cabinet body 2. Since this purely mechanical manual lifting method has a low failure rate and the height of the cabinet body 2 after lifting is easy to fix, it has the advantages of simple structure, easy operation and good durability.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
