Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas stove technology, and more specifically, to a stove lifting mechanism. Background Technology
[0002] In modern kitchens, kitchen appliances are often integrated with cabinets. For example, gas cooktops are often installed using a built-in method. This involves drilling a hole in the countertop, inserting the cooktop's base into the hole, and placing the cooktop's panel on the countertop. The advantages of this built-in installation are that the cooktop and cabinets are integrated, creating a neat and aesthetically pleasing look. During operation, the cooktop is fixed in the mounting hole and does not move, facilitating cooking. However, the disadvantages are that the cooktop's panel rests on the countertop. Since the cooktop often needs to be removed for maintenance or adjustments, gaps exist between the countertop and the cooktop panel. Water from cleaning and cooking grease can seep into the cabinets below, affecting the storage of items. Furthermore, the unevenness between the countertop and cooktop panel makes cleaning more difficult.
[0003] With the increasing demand for refined kitchens, slab cooktops, which are installed on kitchen countertops, are becoming increasingly popular. In a slab cooktop design, the countertop directly serves as the cooktop panel. Holes are drilled in the countertop, and the burner head is exposed through these holes. Compared to traditional built-in cooktops, there is no protruding cooktop panel; the entire countertop is a flat, one-piece structure, resulting in a neat, elegant appearance and easy cleaning.
[0004] However, existing slab stoves still have some shortcomings, such as installation difficulties. The main reason is the inconsistent thickness of the slab countertop. This means that during installation, the stove's underside must be lifted by hand or with tools from below the countertop to the appropriate height based on the countertop's thickness, ensuring the burner is in the correct position before securing it to the cabinet. Due to limited space under the countertop, this operation is inconvenient, requiring one person to monitor the stove's position while another person installs and secures it from below, making it time-consuming and labor-intensive. Summary of the Invention
[0005] To overcome at least one of the defects in the prior art, this utility model provides a stove lifting mechanism that allows the stove height to be adjusted from above the countertop. This mechanism is not only easy to operate, but also allows for installation and adjustment by a single person, improving work efficiency and saving labor costs.
[0006] This utility model provides a stove lifting mechanism, including a first connecting seat and an adjusting shaft. The first connecting seat is connected to the stove housing and has a vertically extending threaded through hole. The lower end of the adjusting shaft is screwed into the threaded through hole, and the bottom of the adjusting shaft is rotatably connected to the stove mounting base in the horizontal direction.
[0007] Compared with the prior art, the stove lifting mechanism of this utility model has the following advantages:
[0008] The stove lifting mechanism of this utility model allows the stove to be pre-connected to the stove mounting base via the lifting mechanism during installation. Then, by operating the adjustment shaft above the countertop, the first connecting seat can be moved up and down under the action of the threaded mating surface, thereby raising the overall height of the stove to the set position. The structure is simple, and there is no need for installers to support the stove from the bottom for height adjustment. It is easy to operate and can be installed and adjusted by a single person.
[0009] Furthermore, the first connecting seat includes a fixing plate, which is vertically connected to the outer wall of the stove housing. The fixing plate is provided with a vertical sleeve, and the inner wall of the vertical sleeve is provided with internal threads to form the threaded through hole.
[0010] As an improvement, a second connecting seat is connected to the stove mounting base, and a mandrel is provided on the second connecting seat. The lower end of the adjusting shaft has a positioning threaded hole, and the upper end of the mandrel is screwed into the positioning threaded hole. The positioning threaded hole and the external thread on the outer wall of the adjusting shaft have opposite directions of rotation. In the above improved structure, the entire lifting structure adopts a double-layer reverse threaded engagement structure, resulting in faster adjustment speed and a wider adjustable range.
[0011] In a further improvement, a balance support assembly capable of vertically raising and lowering is provided between the second connecting seat and the housing of the stove.
[0012] Furthermore, the balance support assembly includes two upper connecting rods, two lower connecting rods, and a balance connecting rod. One end of each of the two lower connecting rods is rotatably connected to the second fixed plate, and one end of each of the two upper connecting rods is rotatably connected to the housing of the stove. The two ends of the balance connecting rod are coaxially hinged to the ends of the two upper connecting rods away from the stove and the ends of the two lower connecting rods away from the second fixed plate, respectively.
[0013] In a further improvement, a positioning shaft, coaxial with the mandrel, is formed protruding outward on the lower end surface of the second fixing plate, and a positioning hole is provided on the stove mounting base for the positioning shaft to be inserted and fitted. In the above improved structure, the positioning shaft and positioning hole enhance the structural strength of the mandrel, prevent skewing during relative rotation with the adjusting shaft, and ensure the stability of the screw adjustment structure.
[0014] In a further improvement, the top of the adjusting shaft is provided with any one of the following: a slotted groove, a cross groove, a Torx groove, or a hexagonal socket. In the above improved structure, the various groove designs make the rotation of the adjusting shaft more convenient, and it can be operated using a suitable screwdriver.
[0015] Additionally, this utility model also provides a slab stove, including a cabinet, a slab countertop, a stove, and a stove mounting base, as well as the aforementioned stove lifting mechanism. The slab countertop is located on the top of the cabinet, and the slab countertop has mounting holes for the burner of the stove to pass through. The stove mounting base is installed on the upper end of the cabinet, and both ends of the stove are connected to the stove mounting base through the stove lifting mechanism. The slab countertop or the liquid collection tray of the stove also has two operation clearance holes corresponding to the two adjustment shafts.
[0016] Other improvements and advantages of this invention will be set forth in the detailed description that follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures particularly pointed out in the description and drawings. Attached Figure Description

[0023] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.
[0024] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.
[0025] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0026] See Figures 1-4 As shown in the illustration, this application discloses a stove lifting mechanism, mainly used in slab stove structures. It includes a first connecting seat and an adjusting shaft 1. The first connecting seat is connected to the stove housing 11, and has a vertically extending threaded through hole 2. The lower end of the adjusting shaft 1 is screwed into the threaded through hole 2, and the bottom of the adjusting shaft 1 is rotatably connected to the stove mounting base 12 in the horizontal direction. In this structure, by turning the adjusting shaft 1, the first connecting seat can be moved up and down under the action of the threaded mating surface, thereby raising the overall height of the stove 11 to a set position. The structure is simple, and it eliminates the need for installers to support the stove 11 from the bottom for height adjustment, making operation convenient.
[0027] In this embodiment, see Appendix Figure 3 The first connecting seat includes a first fixing plate 3, which is vertically connected to the outer wall of the stove 11 housing. A vertical sleeve 4 is provided on the fixing plate, and the inner wall of the vertical sleeve 4 has internal threads to form a threaded through hole 2. Preferably, the fixing plate is detachably connected to the outer wall of the stove 11 housing by screws, and the fixing plate and the vertical sleeve 4 are an integral structure, which is convenient for processing. In some other embodiments, the fixing plate can also be directly welded to the outer wall of the stove 11 housing.
[0028] For further details, please refer to the appendix. Figure 3 In this embodiment, a second connecting seat is connected to the stove mounting base 12, and a spindle 5 is provided on the second connecting seat. A positioning threaded hole 6 is provided at the lower end of the adjusting shaft 1, and the upper end of the spindle 5 is screwed into the positioning threaded hole 6. The positioning threaded hole 6 and the external thread on the outer wall of the adjusting shaft 1 have opposite directions of rotation. In this structure, the second connecting seat includes a second fixing plate 7 horizontally connected to the stove mounting base 12, and the lower end of the spindle 5 is fixedly connected to the upper end face of the second fixing plate 7. With this configuration, the entire lifting structure adopts a double-layer reverse threaded engagement structure, resulting in faster adjustment speed and a wider adjustable range. Preferably, the spindle 5 and the second fixing plate 7 are integrally machined, which facilitates processing and saves costs.
[0029] In the above structure, to further ensure the stability of the stove 11 during height adjustment, a vertically retractable balance support assembly is provided between the second fixing plate 7 and the housing of the stove 11. For details, please refer to the appendix. Figure 3 , 4 The balance support assembly includes two upper connecting arms 18, two lower connecting arms 19, and a balance connecting rod 20. One end of each of the two lower connecting arms 19 is rotatably connected to the side wall of the second fixed plate 7. One end of each of the two upper connecting arms 18 is rotatably connected to the housing of the stove 11. The two ends of the balance connecting rod 20 are coaxially hinged to the ends of the two upper connecting arms 18 away from the stove 11 and the ends of the two lower connecting arms 19 away from the second fixed plate 7, respectively.
[0030] More specifically, in this embodiment, the first fixing plate 3 has a connecting through hole, through which connecting screws for connecting to the stove 11 housing are inserted, enabling detachable connection of the corresponding parts and facilitating subsequent maintenance and replacement. Of course, in other embodiments, if disassembly is not a concern, the first fixing plate 3 can be directly welded to the stove 11 housing. The second fixing plate 7 can be connected to the stove mounting base 12, or it can be left unconnected and directly rest against the stove mounting base 12, serving to support the stove.
[0031] See appendix Figure 4 A positioning shaft 16, coaxial with the spindle 5, is formed protruding outward on the lower end surface of the second fixing plate 7. A positioning insertion hole 17 is provided on the stove mounting base 12 for the positioning shaft 16 to be inserted and fitted. The positioning shaft 16 and the positioning insertion hole 17 improve the structural strength of the spindle 5, prevent skewing during relative rotation with the adjusting shaft 1, and ensure the stability of the screw adjustment structure.
[0032] In some other embodiments, the lower end of the adjusting shaft 1 can also be rotatably connected to the stove mounting base 12 via a plane bearing. By rotating the adjusting shaft 1, the stove 11 is driven to rise and fall under the action of its outer wall and the threaded through hole 2.
[0033] On the other hand, in the above structure, the outer peripheral wall of the bottom end of the adjusting shaft 1 has a protruding limiting boss (not shown in the figure) to prevent the adjusting shaft 1 from disengaging from the threaded through hole 2 due to excessive rotation, thus ensuring safety in use.
[0034] In this embodiment, a slotted groove, a Phillips head groove, a Torx groove, or a hexagonal socket is formed on the top of the adjusting shaft 1. This allows for easy adjustment using a screwdriver, saving time and effort. Alternatively, in other embodiments, a manual knob can be directly connected to the top of the adjusting shaft 1.
[0035] On the other hand, see Appendix Figure 1 This application also discloses a slab stove, including a cabinet 9, a slab countertop 10, a stove 11, and a stove mounting base 12, and also includes the aforementioned stove 11 lifting mechanism. The slab countertop 10 is located on the top of the cabinet 9, and the slab countertop 10 has a mounting hole 13 for the burner of the stove 11 to pass through. After the stove 11 is installed, a liquid collection tray 14 is installed on the slab countertop 10 at a position corresponding to the mounting hole 13. The stove mounting base 12 is installed on the upper end of the cabinet 9, and both ends of the stove 11 are connected to the stove mounting base 12 through the stove lifting mechanism. The slab countertop 10 or the liquid collection tray 14 of the stove 11 also has an operation clearance hole 15 corresponding to the adjustment shaft 1. Of course, in this structure, a sealing cover can also be detachably embedded in the operation clearance hole 15.
[0036] In this embodiment, the slab stove has a dual-burner structure, that is, the stove 11 includes two burners. Correspondingly, two mounting holes 13 are opened on the slab countertop 10, and each of the two mounting holes 13 is connected to a liquid collection tray 14. The two lifting mechanisms at both ends of the stove 11 correspond to the positions of the two mounting holes 13, and the two adjusting shafts 1 correspond to the two liquid collection trays 14. For easy adjustment, operation clearance holes 15 are opened on the two liquid collection trays 14, so that the height of the stove 11 can be finely adjusted even after the liquid collection trays 14 are installed. Specifically, the adjusting shafts 1 can be rotated by inserting a special screwdriver into the operation clearance hole 15, which is very convenient.
