[0047] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0048] Embodiment 1:

[0049] A cabinet height adjustment device, such as Figure 1-12 As shown, it includes a connecting component 1 and an adjusting component 2.

[0050] The connecting assembly 1 is a fixed end of the height adjustment device, and is rigidly connected to the four corners of the cabinet bottom plate during use.

[0051] like Figure 1 and Figure 2 As shown, the connection assembly 1 includes a cabinet connection base 11, a lifting shaft 12 and a base 13.

[0052] The adjustment foot structures currently on the market, whether two-stage or three-stage, cannot achieve installation fine-tuning.

[0053] In the three-stage structure provided by this solution, the gear structure at the bottom of the base is fine-tuned by adjusting the price claw, which can save the installation time of on-site installation workers and improve the adjustment accuracy.

[0054] In this scheme, if Figure 3-5 As shown, the cabinet connecting seat 11 includes a connecting plate 111 and a sleeve 112 .

[0055] The connecting plate 111 includes a first mounting hole 1111 and a second mounting hole 1112 .

[0056] Specifically, the screw passes through the first mounting hole 1111 to rigidly connect the connecting base to the vertical plate of the cabinet; the screw passes through the second mounting hole 1112 to rigidly connect the cabinet connecting base 11 to the cabinet bottom plate.

[0057] The cabinet connecting seat 11 provided in this solution has a simple structure and is adaptable to different cabinet bottom plate structures; at the same time, after the first mounting hole 1111 is rigidly connected to the cabinet, the overall stability is enhanced.

[0058] During the production process, some cabinet manufacturers set raised positioning pieces on the four corners of the cabinet bottom plate to facilitate the work of the installers;

[0059] In this embodiment, a positioning hole 1113 is provided in the middle of the connecting plate 111. During the installation process, the positioning hole 1113 is limited on the positioning member.

[0060] A sleeve 112 is disposed around the positioning hole 1113, and the sleeve 112 is used to limit the fixed end of the lifting shaft 12;

[0061] After the sleeve 112 is assembled with the lifting shaft 12 and the base 13,

[0062] The initial height is 8 cm, 10 cm or 12 cm. During the upward lifting process, the number of threads on the lifting shaft 12 must be certain and tightly combined with the base 13 to ensure stability and firmness.

[0063] Preferably, after adjusting to the highest state, the height increases by 2 cm;

[0064] That is, the height when adjusted to the highest state is 10 cm, 12 cm or 14 cm.

[0065] In this solution, the height of the sleeve 112 is directly adjusted. This process of lengthening or shortening the hollow cylinder only requires replacing the mold wheel, which is very simple and does not require consideration of threads or other structures.

[0066] In this embodiment, after the sleeve 112 is assembled with the lifting shaft 12 and the base 13, the initial height of the entire device is 8 cm. When adjusted to the highest state, the height of the entire device is 10 cm.

[0067] The support structures 1121 are evenly distributed around the sleeve 112 , and the support structures 1121 improve the overall stability of the cabinet connection base 11 . In this embodiment, three support structures 1121 are provided, distributed between the first mounting hole 1111 and the second mounting hole 1112 .

[0068] like Figure 6 As shown, the lifting shaft 12 is divided into a screw rod 121 and a connecting head 122 .

[0069] The screw rod 121 is a lifting end. The threads on the outside of the screw rod 121 fit with the threads on the inside of the base 13 , and the screw rod 121 is lifted and displaced in the base 13 .

[0070] The connector 122 is a limiting end, and a protruding platform 123 is provided at the junction of the connector 122 and the screw rod 121. This structural setting enables the connector 122 to adapt to sleeves 112 of any size, and is limited on the sleeve 112 by the platform 123, which does not affect the operation of the screw rod 121 and also increases stability.

[0071] The outer side of the connecting head 122 is evenly distributed with limiting teeth 1221 , and the limiting teeth 1221 increase the friction force to ensure the stability between the lifting shaft 12 and the cabinet connecting seat 11 .

[0072] Specifically, the screw rod 121 is tightened with the base 13 , and after the cabinet connecting seat 11 is fixed with the cabinet bottom plate, the connector 122 is inserted into and limited in the sleeve 112 .

[0073] like Figure 7 and Figure 8 As shown, a gear structure 132 is provided at the bottom of the base 13 and the stud 131 .

[0074] The inner thread of the stud 131 is meshed with the outer thread of the screw rod 121;

[0075] In this embodiment, forty saw teeth are evenly distributed on the outer side of the gear structure 132;

[0076] In the structural setting of this solution, the gear structure 132 is rotated by external force, and the height adjustment device is raised by 3 mm as a whole for every 360° rotation of the gear, and can be raised by 2 cm at most.

[0077] Specifically, the bottom of the base 13 is in contact with the ground, and when the outer gear structure 132 rotates forward / reversely, the base 13 is driven to rotate, and the other end of the lifting shaft 12 engaged in the base 13 is limited on the cabinet connecting seat 11. According to the principle of relative motion of force, the base 13 keeps rotating in place, and the lifting shaft 12 rotates to produce upward / downward displacement.

[0078] The adjusting component 2 acts on the connecting component 1 to control the lifting and lowering of the connecting component 1 and change the height of the connecting component 1 .

[0079] Most preferably, during the adjustment process, the adjustment component 2 provided by the present solution is used.

[0080] like Fig. 9 As shown, the adjustment assembly 2 includes an adjustment claw 21, a connecting member 22 and a connecting rod.

[0081] During the installation process, in order to ensure that the heights of the four corners of the cabinet are consistent, workers are required to bend over and reach their hands into the bottom of the cabinet to manually rotate the height adjustment device until the four corners are at the same height. During the adjustment process, the height cannot be accurately controlled, and it is also time-consuming and laborious.

[0082] In the prior art, there is also an adjustment structure in which a rotating rod is embedded between the adjustment claw and the connecting rod, and the adjustment head protrudes from the inner side of the adjustment claw. The connecting assembly is driven to rotate and lift by rotating the wedge-shaped teeth at the control end at the rotating rear end. However, the disadvantage is that the structure is too complicated.

[0083] The adjustment component 2 provided in the present solution has a simple structure and can adjust the angle. The height of the connection component 1 can be controlled by rotating forward or reversely after flipping.

[0084] It is worth mentioning that the adjustment component 2 and the gear structure 132 provided in this solution are combined to form a ratchet mechanism, which is easy to manufacture and the size of the ratchet angle can accurately control the lifting height to achieve cabinet balance.

[0085] like Figure 9-11 As shown, the adjusting claw 21 is composed of a claw body 211 and an upper cover 212. A pawl 213 and a spring 214 are arranged in the inner cavity of the adjusting claw 21. The claw body 211 and the upper cover 212 respectively include a connecting seat body 215 with an arc-shaped groove, which are movably connected to the connecting member 22 when closed.

[0086] like Fig.12As shown, the first connecting end 221 of the connecting member 22 is a cylinder, which is movably connected in the adjusting claw 21, with a wedge-shaped structure in the middle and the other end being a second connecting end 222. In this embodiment, the second connecting end 222 is a threaded connection structure connected to the retractable rod.

[0087] like Fig.13 As shown, in the structural setting of the present solution, a light module 23 is arranged on the side of the adjusting claw 21, and the light module 23 includes an LED lamp 231, a battery 232 and a switch 233. Adding this structural feature makes it more convenient to use in the scene mode where the bottom of the cabinet is darker.

[0088] During operation, the connecting member 22 can be adjusted upward / downward by 10° in combination with the telescopic rod. During the adjustment, there is no need for workers to bend over the ground to operate, which is very user-friendly. When not in use, the telescopic rod can be shrunk and placed in the tool bag.

[0089] The telescopic rod can be provided with a thread engaged with the second connecting end 222 at one end, and no specific requirements are made on the length and style. Of course, a foldable rod can also be used instead of the telescopic rod. The telescopic rod or folding rod is a prior art, which is not illustrated with drawings. As a technical common sense known to those skilled in the art, no further description is given here.

[0090] Example 2

[0091] The features of this embodiment that are different from those of Embodiment 1 are as follows:

[0092] In this embodiment, reference Fig.14 As shown, the tops of both ends of the claw body 211 include clamping portions 216 .

[0093] The combination of the clamping portion 216 and the claw body 211 provided in the present solution enables the adjustment component 2 to adjust the connection components 1 of different styles or specifications, thereby making the application scope of the present solution wider.

[0094] Specifically, when the gear structure 132 at the bottom of the base 13 is replaced with a multi-faceted shape, the clamping portion 216 is combined with the two ends of the claw body 211 through the fixing element 2161, and the clamping surface of the claw body 211 is changed from the original arc state to the multi-faceted state. When the claw body 211 clamps the bottom of the base 13, the cross-section formed fits the cross-section of the bottom of the base 13.

[0095] In summary, the cabinet connecting seat provided in the present application has a simple structure and is adaptable to different cabinet bottom plate structures. After the first mounting hole is rigidly connected to the cabinet, the overall stability is enhanced.

[0096] The adjustment assembly and gear structure provided in the present application are combined to form a ratchet mechanism, which is easy to manufacture, and the size of the ratchet angle can accurately control the height of the lift to achieve cabinet balance;

[0097] The connecting piece provided in the present application can be adjusted upward / downward by 10°, and workers do not need to bend over the ground to operate, which is very user-friendly.

[0098] The above implementation is only to illustrate the technical concept and features of this solution, and its purpose is to enable people familiar with this technology to understand the content of this solution and implement it accordingly, and it cannot be used to limit the protection scope of this solution. Any equivalent transformation or modification made according to the spirit of this solution should be included in the protection scope of this solution.
