In its technical solution, elastic clamping parts are provided on both sides of the bottom of the shelf, and the elastic clamping parts include clamping joints that can extend along the width direction of the shelf. A clamping groove that matches the clamping joint and a shelf groove that matches the shelf edge are provided on the refrigerator. When the shelf is installed in the refrigerator, the shelf edge is placed in the shelf groove, and the shelf is pushed to move along the shelf groove. When the clamping joint on the shelf moves to the position of the clamping groove, based on the elastic force of the elastic clamping part (the elastic clamping part includes a spring), the clamping joint can be pushed and extended into the clamping groove, thereby establishing a clamping relationship between the clamping joint and the clamping groove, and the shelf is fixed in the refrigerator.

[0004] The above-mentioned shelf and refrigerator have the following technical problems in practical application:

[0005] If the lever provided on the elastic card connector is triggered by mistake, the lever will be pulled outward, overcoming the elastic force of the spring, and the card connector will move outward from the card slot on the refrigerator body, thereby causing the shelf to separate from the refrigerator. The shelf and the items placed on the shelf will be at risk of falling. In this case, it is easy to cause damage and loss of items to the user, and may also cause physical harm to people. Summary of the invention

[0007] The clamping mechanism provided by the present invention is installed on a first component and is used to clamp and fix the first component with a second component, and the clamping mechanism includes a sliding limiter and an elastic member; a guide column is provided on the first component, and an angle between the guide column and the first direction and the second direction is less than 90 degrees; the first direction is the direction in which the first component moves relative to the second component, and the second direction is perpendicular to the first direction; the sliding limiter includes a first column portion and a second column portion connected to each other; the first column portion is slidably connected to the guide column, and the angle between the first column portion and the second column portion is less than 90 degrees, and when the first column portion is slidably connected to the guide column, the second column portion is perpendicular to the connecting surface of the second component and the first component along the second direction; when the first column portion approaches the first end of the guide column, the second column portion moves toward the second component, and the second column portion can move to protrude from the opposite surface of the first component and the second component, and be plugged into the slot provided on the second component; the elastic member is connected to the first column portion to apply elastic force to the first column portion so that the first column portion tends to the first end of the guide column.

[0008] Wherein, the first column part is annular and has an inner hole; the inner hole of the first column is sleeved on the guide column.

[0009] Wherein, a circumferential limiting surface is arranged on the first column part, and the circumferential limiting surface cooperates with the guide column to limit the rotation of the first column part relative to the guide column in the circumferential direction.

[0010] The cross-sectional shape of the inner hole of the first column portion is a polygon, an ellipse or a curve shape with a variable curvature; and the guide column has a cross-sectional shape matching the inner hole.

[0011] Wherein, the elastic member is a spring, and the spring is sleeved on the guide column. One end of the spring is located at the second end of the guide column, and the other end abuts against the first column portion.

[0012] The shelf provided by the present invention comprises a shelf body and the above-mentioned clamping mechanism, wherein the shelf body is the first component and the clamping mechanism is arranged at the front end of the shelf body.

[0013] There are two clamping mechanisms, which are respectively arranged on two opposite sides of the front end of the shelf body.

[0014] Wherein, a second connecting portion is provided at the rear end portion of the shelf body, and the second connecting portion is used to be connected and fixed to the second component.

[0017] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0018] The clamping mechanism, shelf and refrigerator provided by the embodiment of the present application, after the clamping mechanism realizes the clamping between the first component and the second component, when the first column portion of the sliding limit portion is triggered by mistake and applies a force in the direction of the second end of the guide column, because the direction of the force is along the oblique direction of the second guide column, which is not the same as the second direction where the second column portion is located, when the first component is not subjected to the force and moves toward the front side thereof, a mutual limit will be formed between the first column portion and the second column portion, resulting in the first column portion being unable to slide along the guide column, and the second column portion being unable to move and retract in the second direction, and thus not being disengaged from the slot. Therefore, the force in the direction of the second end of the guide column applied to the sliding limit portion by the above-mentioned mistaken triggering will not cause the clamping fixation between the first component and the second component to be destroyed, thereby making the clamping fixation between the first component and the second component by the clamping mechanism stable and reliable.

[0039] In one embodiment of the clamping mechanism provided by the present invention, Figures 1 to 10As shown, the clamping mechanism 30 is installed on the first component and is used to clamp and fix the first component and the second component. The clamping mechanism 30 includes a sliding limiter 31 and an elastic member 32; the first component is provided with a guide column 12, and the guide column 12 has an angle less than 90 degrees with the first direction and the second direction; the first direction is the direction in which the first component moves relative to the second component, and the second direction is perpendicular to the first direction; the sliding limiter 31 includes a first column portion 311 and a second column portion 312 connected to each other; the first column portion 311 is slidably connected to the guide column 12, and the angle between the first column portion 311 and the second column portion 312 is less than 90 degrees, and the first column portion 311 slides When the second column portion 312 is dynamically connected to the guide column 12, the second column portion 312 is perpendicular to the connecting surface of the second component and the first component along the second direction; when the first column portion 311 approaches the first end of the guide column 12, the second column portion 312 moves toward the second component, and the second column portion 312 can move to protrude from the opposite surface of the first component and the second component, and be plugged into the slot 21 set on the second component; the elastic member 32 is connected to the first column portion 311 to apply elastic force to the first column portion 311, so that the first column portion 311 tends to the first end of the guide column 12.

[0040] In this embodiment, the types of the first component and the second component that are clamped and fixed by the clamping mechanism 30 are not limited, and the clamping mechanism 30 described in this embodiment can be applied as long as the first component and the second component are clamped and fixed. In the following description, the shelf 10 is used as the first component and the refrigerator 20 is used as the second component to describe in detail multiple implementation schemes of the clamping mechanism 30 to achieve clamping and fixing between the first component and the second component.

[0041] When the shelf 10 is fixed in the refrigerator 20 by the clamping mechanism 30, it has an inner end located deep in the refrigerator 20 and an outer end located at the opening of the refrigerator 20. In this embodiment, the inner end of the shelf 10 (at Figure 1 The upper part is the front end, and the outer end of the shelf 10 (at Figure 1 The lower part is the middle part) is the rear end, and the left and right sides (at the Figure 1 The left side and the right side are the left side and the right side, and the upper and lower sides when the shelf 10 is placed in the refrigerator 20 are the upper and lower sides. Therefore, the first direction in this embodiment is actually the front-to-back direction of the shelf 10, and the second direction is the left-right direction of the shelf 10.

[0042] In this embodiment, the guide post 12 is disposed on the shelf 10 as the first component, and the length direction of the guide post 12 is neither in the first direction nor in the second direction, that is, the guide post 12 is inclined on the shelf 10, and has a non-90 degree angle with the front-to-back direction and the left-to-right direction of the shelf 10. With respect to the guide post 12, in combination with its inclined direction, its first end is located at the obliquely upward front side and the outer side, and its second end is located at the obliquely upward rear side and the inner side.

[0043] In actual implementation, the guide post 12 can be formed on the shelf 10 in a fixed and inseparable manner, for example, the guide post 10 is integrally formed with other components on the shelf 10. Alternatively, the guide post 12 can also be installed and fixed to the shelf 10 in a movable and detachable manner, for example Figure 3 , Figure 4 and Figure 8 The guide post 12 shown is inserted into the hole groove on the shelf 10, and latches are provided at both ends of the guide post 12 to limit the position, so as to prevent the guide post 12 from moving out of the hole groove. In the latter embodiment, the guide post 12 can be used as a structural component of the shelf 10 or as a component of the clamping mechanism 30 during actual product manufacturing and sales.

[0044] In this embodiment, the sliding limit portion 31 includes a first column portion 311 and a second column portion 312, wherein the first column portion 311 and the guide column 12 are slidingly connected, and a set angle is provided between the first column portion 311 and the second column portion 312, and the value of the angle is the same as the angle value of the angle between the guide column 12 and the second direction. Such a setting can ensure that when the first column portion 311 and the guide column 12 are slidingly connected, the length direction of the second column portion 312 is in the second direction, that is, in the left and right direction of the shelf 10; when the first column portion 311 slides along the guide column 12, the moving direction of the second column portion 312 is also extended and retracted along the left and right direction of the shelf 10 perpendicular to the inner wall of the refrigerator 20 (the area opposite to the left and right sides of the shelf 10).

[0045] In this embodiment, the elastic member 32 provides elastic force to the sliding limit portion 31, and the direction of the elastic force is toward the first end of the guide column 12, that is, along the oblique direction of the guide column 12 toward the front and the outside. The elastic force acts on the sliding limit portion 31. In the absence of other external forces, the first column portion 311 can be located at the first end of the guide column 12, and at this time, the second column portion 312 extends outward from the left and right sides of the shelf 10, and the extended length reaches a maximum; and in the case where other external forces act on the sliding limit portion 31, the elastic force of the elastic member 32 acting on the sliding limit portion 31 makes the first column portion 311 have a tendency to move to the first end of the guide column 12.

[0046] In the present embodiment, when the locking mechanism 30 locks and fixes the shelf 10 and the refrigerator 20, first, after the sliding limit portion 31 and the elastic member 32 of the locking mechanism 30 are assembled onto the shelf 10, the shelf 10 is moved to a corresponding position inside the refrigerator 20 (the refrigerator 20 has a shelf slot or other structure corresponding to the shelf 10), and the first column portion 311 of the sliding limit portion 31 is directly pulled by hand (or other structures are used to act on the first column portion 311 in an indirect manner, which will not be repeated), and force is applied toward the second end of the guide column 12 to overcome and offset a part of the elastic force of the elastic member 32, so that the first column portion 311 moves toward the second end of the guide column 12; in the process of the first column portion 311 moving toward the second end of the guide column 12, the second column portion 312 will retract toward the shelf 10 until its head end no longer protrudes from the left or right sides of the shelf 10, at which time, the shelf 10 can be placed on the shelf slot or other corresponding structure inside the refrigerator 20.

[0047] Thereafter, the force applied to the first column portion 311 is removed, and under the elastic force of the elastic member 32 on the sliding limit portion 31, the first column portion 311 will move a certain distance toward the first end of the guide column 12, and the second column portion 312 will move outward from the left and right sides of the shelf 10 until the head end of the second column portion 312 abuts against the inner wall of the refrigerator 20. Under the action of this abutment relationship, the sliding limit portion 31 will remain fixed on the guide column 12.

[0048] After that, the shelf 10 is pushed to move into the refrigerator 20, that is, the shelf 10 moves toward the front side thereof until it moves to the target position. A slot 21 is provided on the refrigerator 20 at the target position, and the slot 21 is located on the moving path of the second column portion 312. After the shelf 10 moves to the target position, the head end of the second column portion 312 no longer abuts against the side wall of the refrigerator 20, and under the elastic force of the elastic member 32, the second column portion 312 will be inserted into the slot 21. When the second column portion 312 and the slot 21 are plugged into each other, the two can limit the shelf 10 and the refrigerator 20 in the front-to-back direction, and a snap-on relationship is actually formed between the shelf 10 and the refrigerator 20.

[0049] After the above-mentioned clamping connection between the shelf 10 and the refrigerator 20 is realized, when the first column portion 311 of the sliding limit portion 31 is triggered by mistake and a force is applied to the second end direction of the guide post 12, since the direction of the force is along the oblique direction of the second guide post 12, and is not in the same direction as the second direction where the second column portion 312 is located, when the shelf 10 is not subjected to the force and moves toward the front side thereof, a mutual limit is formed between the first column portion 311 and the second column portion 312, so that the first column portion 311 cannot slide along the guide post 12, and the second column portion 312 cannot move and retract in the second direction, and thus will not be separated from the slot 21. Therefore, the force applied to the second end direction of the guide post 12 by the sliding limit portion 31 due to the above-mentioned mistaken triggering will not cause the clamping connection between the shelf 10 and the refrigerator 20 to be destroyed, and the risk of damage to the items placed on the shelf 10 can also be avoided.

[0050] If the shelf 10 needs to be removed from the refrigerator 20, the actual method is as follows: apply force to the first column 311 of the sliding limiter 31, and apply force to the shelf 10 at the same time; the force applied to the first column 311 is directed toward the second end of the guide post 12, and the force applied to the shelf 10 is directed toward the front end of the shelf 10. Fig.10 As shown, the first column part 311 of the sliding limit part 31 can move toward the second end of the guide column 12, and the head end of the second column part 312 retracts toward the shelf 10. Finally, when the shelf 10 moves a certain distance toward its front end, the head end of the second column part 312 no longer protrudes from the left and right sides of the shelf 10, and it is disengaged from the slot 21. At this time, the plug-in relationship between the second column part 312 and the slot 21 is released, and for the shelf 10 and the refrigerator 20, the clamping and fixing relationship between the two is released. At this time, the shelf 10 can be taken out of the refrigerator 20.

[0051] It is understandable that in order to ensure that the shelf 10 can be removed from the refrigerator 20, it is necessary to ensure that the shelf 10 can effectively move a sufficient distance (in the direction of the front side) in the process of removal. Fig.10 The second column portion 312 is shown as moving from the slot 21 to Fig.10 The second column 312 in the figure points to the dotted line frame), so that the head end of the second column 312 can be retracted and disengaged from the slot 21, and a sufficient distance needs to be reserved between the front end of the shelf 10 and the rear wall of the refrigerator 20. This is an inherent requirement of the technical solution of the present invention. In actual implementation, the reserved distance can be set as needed.

[0052] In an embodiment of the clamping mechanism, the first column portion 311 is annular and has an inner hole; the inner hole of the first column 311 is sleeved on the guide column 12 .

[0053] In this embodiment, the first column portion 311 is set to be annular, and its inner hole is sleeved with the guide column 12, so that the first column portion 311 can slide relatively along the guide column 12, and the structure is simple and the cost is low.

[0054] In an embodiment of the clamping mechanism, a circumferential limiting surface is provided on the first column portion 311 , and the circumferential limiting surface cooperates with the guide column 12 to limit the first column portion 311 from rotating relative to the guide column 12 in the circumferential direction.

[0055] In this embodiment, a circumferential limiting surface is provided on the first column portion 311, and the circumferential limiting surface cooperates with the guide column 12. Through the circumferential limiting surface, the rotation between the first column portion 311 and the guide column 12 can be limited, so that when the first column portion 311 is sleeved on the guide column 12, the second column portion 312 can always remain in the second direction, and the head end of the second column portion 312 is always facing the inner wall of the refrigerator 20 opposite to the left and right sides of the shelf 10.

[0056] In one embodiment of the clamping mechanism, the cross-sectional shape of the inner hole of the first column portion 311 is polygonal, elliptical or a curve with variable curvature; the guide column 12 has a cross-sectional shape matching the inner hole.

[0057] In this embodiment, when the cross-sectional shape of the inner hole of the first column portion 311 is a non-circular shape such as a polygon, an ellipse or a curve shape including a variable curvature, the overall cross-sectional shape of the inner hole of the first column portion 311 constitutes a circumferential limiting surface, which can limit the relative rotation between the first column portion 311 and the guide column 12 in the circumferential direction.

[0058] In an embodiment of the clamping mechanism, the elastic member 32 is a spring, which is sleeved on the guide column 12 , with one end of the spring located at the second end of the guide column 12 and the other end abutting against the first column portion 311 .

[0059] In this embodiment, a spring is selected as the elastic member 32 , and the spring only needs to be sleeved on the guide column 12 so that one end thereof abuts against the second end of the guide column 12 (or other fixed area on the shelf 10 ) and the other end abuts against the first column portion 311 .

[0060] In one embodiment of the shelf provided by the present invention, the shelf 10 comprises a shelf body 11 and the clamping mechanism 30 described in the above embodiment. The shelf body 11 is the first component, and the clamping mechanism 30 is arranged at the front end of the shelf body 11.

[0061] In this embodiment, the front end of the shelf body 11 is the front end of the shelf 10 in the aforementioned embodiment, and correspondingly, the rear end of the shelf body 11 (see description below) is the rear end of the shelf 10, and the two opposite sides of the front end of the shelf body 11 (see description below) are the left and right sides of the shelf 10.

[0062] In this embodiment, the shelf 10 includes the snap-fitting mechanism 30 described in the aforementioned embodiment. Through the snap-fitting mechanism 30, the shelf 10 can be snap-fitted and fixed to the refrigerator 20, and the snap-fitting and fixing between the shelf 10 and the refrigerator 20 will not be released due to erroneous triggering of the snap-fitting mechanism 30, thereby making the snap-fitting and fixing between the shelf 10 and the refrigerator 20 stable and reliable, and can effectively protect the shelf 10 and the items placed on the shelf 10.

[0063] In an embodiment of the shelf, the number of the clamping mechanisms 30 is two, and they are respectively disposed at two opposite sides of the front end of the shelf body 11 .

[0064] In this embodiment, the snap-fitting mechanisms 30 are respectively provided on two opposite sides, i.e., the left and right sides, of the front end of the shelf body 11, so as to better snap-fit ​​and fix the shelf 10 and the refrigerator 20, thereby achieving a better snap-fit ​​and fixing effect.

[0065] In an embodiment of the shelf, a second connecting portion 13 is provided at the rear end of the shelf body 11 , and the second connecting portion 13 is used to be connected and fixed to the second component.

[0066] In this embodiment, a second connection portion 13 is provided at the rear end of the shelf body 11, and the second connection portion 13 can be connected and fixed with the refrigerator 20. When the second connection portion 13 is connected and fixed with the refrigerator 20, the movement between the shelf 10 and the refrigerator 20, especially the movement in the front-back direction, can be restricted. In this case, when the connection between the second connection portion 13 and the refrigerator 20 is fixed, even if the first column portion 311 of the clamping mechanism 30 in the aforementioned embodiment is triggered by mistake and force is applied, the plug-in relationship between the second column portion 312 and the slot 21 cannot be destroyed, so that the second connection portion 13 can play a role in protecting the clamping mechanism 30.

[0067] In one embodiment of the shelf, the second connecting portion 13 is a protrusion, and the protrusion is aligned with a recessed portion provided on the second component.

[0068] In this embodiment, the second connection part 13 and the refrigerator 20 can be connected and fixed only by the protrusion of the second connection part 13 and the recess on the refrigerator 20. The structure is simple, the cost is low, and it is easy to operate and install.

[0069] In an alternative embodiment, the second connection part 13 is a concave part, and the concave part is aligned with the protrusion provided on the second component. The method of connecting and fixing the second connection part 13 and the refrigerator 20 by concave-convex matching is similar to the above, and will not be repeated.

[0070] In an embodiment of the refrigerator provided by the present invention, the refrigerator 20 includes the shelf 10 described in the above embodiment, and the inner wall of the refrigerator 20 is the second component.

[0071] In this embodiment, the refrigerator 20 includes the shelf 10 described in the above embodiment, which includes all technical features of the above shelf 10 and of course has the same beneficial effects as the above shelf 10, which will not be repeated.
