Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
In the present invention, unless otherwise specified, use of directional terms such as "upper, lower, left, right, top, bottom" is generally made with respect to the orientation shown in the drawings or with respect to the positional relationship of the components with respect to each other in the vertical, or gravitational direction. The term "inside" and "outside" refer to the inside and the outside of the contour of each member itself.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
According to an aspect of the present invention, an embodiment of the present invention provides an adjustment foot mounting structure including: a mounting assembly 10 and an adjustment foot assembly 20. Wherein the mounting assembly 10 is provided with a threaded mounting hole 11, as shown in fig. 5. As shown in fig. 3 and 4, the adjusting foot assembly 20 includes a support foot 22 and a protrusion 21 protruding from the support foot 22, the protrusion 21 having an external thread to be engaged with the threaded mounting hole 11. Further, in order to prevent the screw coupling between the screw mounting hole 11 of the mounting assembly 10 and the protrusion 21 of the adjustment foot assembly 20 from being loosened, the adjustment foot mounting structure further includes a locking structure including a first locking portion 12 provided on the mounting assembly 10 and a second locking portion 23 provided on the adjustment foot assembly 20 and adapted to be engaged with the first locking portion 12.
Fig. 2 shows the installation of the mounting assembly 10 and the adjustment foot assembly 20. During installation, the extension part 21 can be aligned to the threaded mounting hole 11 on the mounting assembly 10, and then the first locking part 12 and the second locking part 23 are screwed, so that the rotation of the extension part 21 of the adjusting foot assembly 20 is prevented, and the adjusting foot assembly 20 is prevented from falling off (particularly during transportation), that is, the threaded connection between the threaded mounting hole 11 and the extension part 21 can be prevented from loosening through the matching of the first locking part 12 and the second locking part 23, so that the structure is simple and easy to implement.
In consideration of cost and in order to improve the versatility of the adjusting foot assembly 20, the extension 21 of the adjusting foot assembly 20 may be a bolt, and specifically, a bolt mounting hole may be provided in the supporting foot 22, and the bolt may be fixed in the bolt mounting hole. Preferably, the bolt can be fixed to the support foot 22 by injection molding, i.e. the support foot 22 can be integrally injection molded.
The first locking portion 12 and the second locking portion 23 may be engaged in any manner capable of preventing the adjustment foot assembly 20 from falling off the mounting assembly 10, for example, the first locking portion 12 and the second locking portion 23 may be snap-fitted, or may be a hook portion engaged with a hole. In the present embodiment, the first locking portion 12 and the second locking portion 23 are engaged by a boss and a recess, specifically, one of the first locking portion 12 and the second locking portion 23 is a boss, and the other of the first locking portion 12 and the second locking portion 23 is a recess. Further, in the present embodiment, as shown in fig. 3 and 5, the first locking portion 12 is a concave pit, and the second locking portion 23 is a convex boss.
As shown in fig. 3 and 4, the support foot 22 has a cantilever 22a, the cantilever 22a is inclined away from the extension 21, the boss is provided at an end of the cantilever 22a, the recess is provided on the mounting assembly 10, and the boss can be engaged with the recess in a state that the cantilever 22a is deformed, preferably, the deformation is elastic deformation, that is, the cantilever 22a is an elastic cantilever. The reason why the boss is matched with the recess in the state that the cantilever 22a is deformed is to better prevent the threaded connection between the threaded mounting hole 11 of the mounting assembly 10 and the extension part 21 of the adjusting foot assembly 20 from loosening, specifically, the elastic cantilever deforms and further compresses the adjusting foot assembly, thereby ensuring that the adjusting foot assembly 20 cannot loosen.
In addition, in order to further ensure that the adjusting foot assembly does not fall off from the mounting assembly 10, one side of the supporting leg 22 close to the mounting assembly 10 is provided with a positioning surface 24 for being attached to the bottom surface 13 of the mounting assembly, and the upper surface of the boss is higher than the positioning surface 24, so that after the adjusting foot assembly 20 is screwed on the mounting assembly 10, the positioning surface 24 of the adjusting foot assembly 20 is attached to the bottom surface 13 of the mounting assembly.
Further, the support foot 22 includes a base 22b and an inverted cone structure extending from the base 22b in a direction adjacent to the mounting assembly 10, the inverted cone structure forming a cantilever 22 a. Of course, the cantilever 22a may be an elongated rod-like structure extending from the base 22b, and it is preferable that the cantilever 22a be an inverted cone-shaped structure extending from the base 22b, only for cost and process reasons. Wherein the upper portion of the inverted cone structure may have an opening, that is, the inverted cone structure has a gradually thinner thickness in a direction approaching the mounting assembly 10, which also provides a certain elasticity to the cantilever 22a, the positioning surface 24 may be located in the opening of the inverted cone structure, and the protruding portion 21 may extend from the positioning surface 24.
The shape of the base 22b may be selected according to the actual situation, and for example, the base 22b is cylindrical. Further, in order to increase the friction coefficient of the outer surface of the base portion 22b, thereby facilitating the worker to screw the protrusion portion 21 in the threaded mounting hole 11, it is preferable that the outer surface of the base portion 22b is provided with an operating portion 22 b-1. The operation portion 22b-1 may have a pattern structure, or may have a structure for facilitating the engagement with a standard tool, such as a vertical pattern structure. In addition, in view of compactness of the structure and uniformity of the force, it is preferable that the central axis of the extension 21 is collinear with the central axis of the support foot 22.
In addition, the number of the first locking portion 12 and the second locking portion 23 may also be determined according to actual conditions, and specifically, the concave pits may be plural and arranged around the threaded mounting hole 11, and the convex bosses may be plural (as shown in fig. 3, the number of the convex bosses is 4) and arranged around the protruding portion 21. Thus, as the alignment foot assembly 20 is tightened, the boss drops into the recess closest to the boss, thereby improving installation efficiency. It should be noted that in the present invention, the number of lands and pits is not necessarily equal.
According to another aspect of the present invention, the refrigerator provided by the embodiment of the present invention comprises the above-mentioned adjusting foot mounting structure, and the mounting assembly 10 is a lower hinge assembly disposed at a lower portion of the refrigerator.
The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Within the scope of the technical idea of the invention, numerous simple modifications can be made to the technical solution of the invention, including combinations of the individual specific technical features in any suitable way. The invention is not described in detail in order to avoid unnecessary repetition. Such simple modifications and combinations should be considered within the scope of the present disclosure as well.
