Description

Technical Field

[0001] The invention relates to a shelf support device for a refrigerator, and in particular to a self-locking and anti-loosening shelf support mechanism and a refrigerator. Background Art

[0002] Existing freezers are equipped with more than one shelf, and these shelves are usually supported and fixed by supporting devices. These supporting devices include a supporting seat and a slide rail. The supporting seat can be slidably installed on the slide rail up and down, and is supported on the supporting boss of the slide rail by the supporting buckle of the supporting seat to achieve fixed placement.

[0003] In order to improve the locking stability and reliability of the support seat, the existing support device is provided with a locking structure, which is used to lock the support buckle of the support seat to prevent the support buckle of the support seat from detaching from the support boss of the slide rail and avoiding the loosening of the shelf. For example, the utility model patent with authorization announcement number CN 216716739 U discloses an easy-to-use shelf column buckle.

[0004] Although the above-mentioned shelf column buckles can increase the stability of the support seat to a certain extent, the greater the weight of the shelf, the greater the possibility that the support buckles of the support seat will detach from the support bosses of the slide rail, and there is still a risk of the shelf loosening without being damaged; and the support bosses are arranged on the front side of the slide rail, and there is only a single support boss between the support buckles and the slide rail for support, which is also prone to loosening when the load is too heavy. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned problems and provide a self-locking and anti-loosening shelf support mechanism, which can effectively prevent the shelf from loosening so that the shelf can be placed stably.

[0006] Another object of the present invention is to provide a refrigerator.

[0007] The purpose of the present invention is achieved through the following technical solutions:

[0008] A self-locking and anti-loosening shelf support mechanism, comprising a support column, a support seat and a support release structure;

[0009] The support column is provided with a sliding adjustment channel, and two opposite side walls of the sliding adjustment channel are provided with a plurality of supporting bosses;

[0010] The support seat is provided with two support buckles respectively used for supporting on two groups of support bosses, the two support buckles are symmetrically arranged and the tops are fixedly connected to the body of the support seat; along the support column from top to bottom, the support buckles are inclined toward the side wall connected to the corresponding support boss;

[0011] The support release structure is used to drive the two support buckles to leave the two groups of support bosses.

[0012] The working principle of the above self-locking and anti-loosening shelf support mechanism is as follows:

[0013] During operation, the support seat is pushed according to the placement height of the shelf, so that the support buckle of the support seat switches between multiple support bosses until it is supported on a support boss of corresponding height. At this time, the two support buckles of the support seat are respectively supported on two opposite support bosses. Furthermore, since the support buckles are inclined toward the side walls connected to the corresponding support bosses from top to bottom along the support column, that is, the two support buckles are in an eight-shaped structure; when goods are placed on the shelf, the weight is transferred downward to the two eight-shaped support buckles, and then transferred to the support bosses through the inclined support buckles; through force analysis, it can be seen that the inclined force acting on the support bosses by the support buckles can be decomposed into vertical and horizontal components, wherein the vertical component is downward and offsets the vertical upward support force of the support bosses, while the horizontal component points to the side walls of the sliding adjustment channel of the support column, and is offset by the horizontal support force of the side walls of the sliding adjustment channel or the support bosses. At this time, the bottoms of the two support buckles are respectively against the side walls of the sliding adjustment channel or the sides of the support bosses. Therefore, no matter how heavy the weight on the shelf is, the two support buckles can be easily transferred to the support column, and the heavier the weight, the greater the friction between the support buckles and the support column, and the greater the resistance to loosening, thereby forming a self-locking effect, which can effectively prevent the shelf from loosening, so that the shelf can be placed stably. In addition, the support seat is supported on two opposite side walls of the sliding adjustment channel of the support column through two symmetrical support buckles, which is a double-point support with greater load-bearing capacity and better stability.

[0014] In a preferred embodiment of the present invention, the support buckle is an elastic support arm integrally formed with the support seat. The integrated production cost is low, the elasticity facilitates the release of the support, and the elastic force can be reliably supported on the support boss.

[0015] In a preferred embodiment of the present invention, the support release structure includes two operating arms, which are arranged opposite to each other, and one end of the two operating arms is respectively fixedly connected to two support buckles. In this way, when the height of the shelf needs to be adjusted, by clamping the two operating arms, the two support buckles can be driven to move toward each other, away from the side wall of the sliding adjustment channel and the support boss, and the limit is released, so that the support seat can be slid vertically, and then the position of the shelf can be adjusted.

[0016] In a preferred embodiment of the present invention, a preload spring is provided between the two support buckles, and the two ends of the preload spring are respectively pressed against the two support buckles. This can cause the two support buckles to be pressed against the corresponding side walls of the sliding adjustment channel, provide preload force, and further improve stability.

[0017] A preferred solution of the present invention, wherein the support release structure includes an integrated swinging member, the integrated swinging member is rotatably connected to the support seat, the integrated swinging member is provided with an operating part and an integrated action part; the integrated action part is provided with two and symmetrically arranged; the two support buckles are provided with a support release transmission part on the opposite side, and the support release transmission part is provided with an inclined guide surface; when the integrated action part is pressed on the inclined guide surface of the support release transmission part, the corresponding support buckle is subjected to a force away from the support boss. Through the above structure, when it is necessary to adjust the height of the shelf, the operating part of the integrated swinging member can be manually pressed in the corresponding direction, so that the integrated action part swings close to the support release transmission part of the support buckle, and when the integrated action part is pressed on the inclined guide surface of the support release transmission part, the integrated action part drives the corresponding support buckle to move in the direction away from the support boss until the support buckle leaves the space above the support boss, and the limit is released, so that the support seat can be vertically slid, and then the position of the shelf can be adjusted. In normal conditions, the two integrated action parts play a role of limiting the two support buckles, and play a role in preventing the two support buckles from loosening.

[0018] Furthermore, the two support buckles each have a locking and pressing portion on one side opposite to the other, and the locking and pressing portion and the support release transmission portion are located on both sides of the swing plane of the integrated action portion; in a direction perpendicular to the swing plane of the integrated action portion, the locking and pressing portion and the support release transmission portion do not overlap;

[0019] The integrated swinging member is provided with an elastic buckling portion; the support seat is provided with a buckling groove matched with the elastic buckling portion; when the elastic buckling portion is matched with the buckling groove, the integrated action portion is attached to the side of the locking and extruding portion. Through the above structure, after adjusting the position of the shelf, the operating portion of the integrated swinging member can be manually pressed in the corresponding direction, so that the integrated action portion swings close to the locking and extruding portion of the support buckle until the integrated action portion is attached to the side of the locking and extruding portion, and the integrated action portion can be limited and locked to prevent the integrated action portion from moving away from the supporting boss autonomously, thereby further improving the stability of the shelf; at this time, when the elastic buckling portion is matched with the buckling groove, the integrated swinging member can be fixed to prevent the integrated swinging member from swinging autonomously, thereby providing a continuous locking force.

[0020] Furthermore, the elastic buckling portion is fixedly connected to the operating portion.

[0021] In a preferred embodiment of the present invention, a support step opening for accommodating the support boss is provided at the bottom of the support buckle.

[0022] In a preferred embodiment of the present invention, the integrated swinging member is an inverted "V" shaped structure, the operating portion and the top of the integrated action portion are connected together, and the top is rotatably connected to the support seat. The advantages are that the structure is compact, the shape matches the support seat, the overall volume is small after installation, and the operation is convenient.

[0023] A freezer comprises the self-locking and anti-loosening shelf support mechanism.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The self-locking and anti-loosening shelf support mechanism of the present invention is provided with two figure-eight support buckles. No matter how heavy the weight on the shelf is, the two support buckles can be easily transferred to the support column. Moreover, the heavier the weight, the greater the friction between the support buckles and the support column, and the greater the resistance to loosening, thereby forming a self-locking effect, which can effectively prevent the shelf from loosening and allow the shelf to be placed stably.

[0026] 2. The support seat of the self-locking and anti-loosening shelf support mechanism of the present invention is supported on two opposite side walls of the sliding adjustment channel of the support column through two symmetrical support buckles, which is a double-point support with greater load-bearing capacity and better stability.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0033] Example 1

[0034] See also Figure 1-2The freezer of this embodiment includes a shelf and a self-locking and anti-loosening shelf support mechanism, and the self-locking and anti-loosening shelf support mechanism includes a support column 1, a support seat 2 and a support release structure; the support column 1 is provided with a sliding adjustment channel 1-1, and two opposite side walls of the sliding adjustment channel 1-1 are provided with multiple support bosses 1-2; the support seat 2 is provided with two support buckles 2-1 respectively used to support on the two groups of support bosses 1-2, and the two support buckles 2-1 are symmetrically arranged and the tops are fixedly connected to the body of the support seat 2; along the support column 1 from top to bottom, the support buckles 2-1 are inclined toward the side wall connected to the corresponding support boss 1-2; the support release structure is used to drive the two support buckles 2-1 to leave the two groups of support bosses 1-2.

[0035] Furthermore, the support buckle 2-1 is an elastic support arm integrally formed with the support seat. The one-piece production cost is low, the elasticity is convenient for releasing the support, and the elastic force can be reliably supported on the support boss.

[0036] See also Figure 1-2 The support release structure includes two operating arms 3, which are arranged opposite to each other, and one end of the two operating arms 3 is respectively fixedly connected to the two support buckles 2-1. In this way, when the height of the shelf needs to be adjusted, by clamping the two operating arms 3, the two support buckles 2-1 can be driven to move toward each other, away from the side wall of the sliding adjustment channel 1-1 and the support boss 1-2, and the limit is released, so that the support seat 2 can be slid vertically, and then the position of the shelf can be adjusted.

[0037] See also Figure 1-2 A preload spring 4 is provided between the two support buckles 2-1, and the two ends of the preload spring 4 are respectively pressed against the two support buckles 2-1. This can cause the two support buckles 2-1 to be pressed against the corresponding side walls of the sliding adjustment channel 1-1, provide preload force, and further improve stability.

[0038] See also Figure 1-2 The working principle of the self-locking and anti-loosening shelf support mechanism of this embodiment is:

[0039] During operation, the support seat 2 is pushed according to the placement height of the shelf, so that the support buckle 2-1 of the support seat 2 switches between multiple support bosses 1-2 until it is supported on the support boss 1-2 of the corresponding height. At this time, the two support buckles 2-1 of the support seat 2 are respectively supported on two opposite support bosses 1-2. Furthermore, since the support buckle 2-1 is inclined from top to bottom along the support column 1, that is, the two support buckles 2-1 are in an eight-shaped structure; when goods are placed on the shelf, the weight is transferred downward to the two eight-shaped support buckles 2-1, and then transferred to the support boss 1-2 through the inclined support buckle 2-1; through force analysis, it can be known that the inclined force of the support buckle 2-1 on the support boss 1-2 can be decomposed into a vertical component and a horizontal component, wherein the vertical component is downward and offsets the vertical upward support force of the support boss 1-2, while the horizontal component points to the support. The side walls of the sliding adjustment channel 1-1 of the support column 1 are offset by the horizontal supporting force of the side walls of the sliding adjustment channel 1-1 or the supporting boss 1-2. At this time, the bottoms of the two supporting buckles 2-1 are respectively against the side walls of the sliding adjustment channel 1-1 or the sides of the supporting boss 1-2. Therefore, no matter how heavy the weight on the shelf is, the two supporting buckles 2-1 can be easily transferred to the supporting column 1. Moreover, the heavier the weight, the greater the friction between the supporting buckles 2-1 and the supporting column 1, and the greater the resistance to loosening, thereby forming a self-locking effect, which can effectively prevent the shelf from loosening and allow the shelf to be placed stably.

[0040] Example 2

Through the above structure, when the height of the shelf needs to be adjusted, the operating part 5-1 of the integrated swinging member 5 can be manually pressed in the corresponding direction, so that the integrated action part 5-2 swings close to the support release transmission part 2-2 of the support buckle 2-1. When the integrated action part 5-2 presses against the inclined guide surface of the support release transmission part 2-2, the integrated action part 5-2 drives the corresponding support buckle 2-1 to move in the direction away from the support boss 1-2 until the support buckle 2-1 leaves the space above the support boss 1-2, releasing the limit, so that the support seat 2 can be slid vertically, and then the position of the shelf can be adjusted.

[0042] Furthermore, there are locking and squeezing parts 2-3 on the opposite sides of the two support buckles 2-1, and the locking and squeezing parts 2-3 and the support release transmission part 2-2 are located on both sides of the swing plane of the integrated action part 5-2; in the direction perpendicular to the swing plane of the integrated action part 5-2, the locking and squeezing parts 2-3 and the support release transmission part 2-2 do not overlap; the integrated swinging part 5 is provided with an elastic buckling part 5-3; the support seat 2 is provided with a buckling groove 2-4 that cooperates with the elastic buckling part 5-3; when the elastic buckling part 5-3 is engaged in the buckling groove 2-4, the integrated action part 5-2 is attached to the side of the locking and squeezing part 2-3. Through the above structure, after adjusting the position of the shelf, the operating part 5-1 of the integrated swinging member 5 can be manually pressed in the corresponding direction, so that the integrated acting part 5-2 swings close to the locking and extrusion part 2-3 of the support buckle 2-1, until the integrated acting part 5-2 is attached to the side of the locking and extrusion part 2-3, and the integrated acting part 5-2 can be limited and locked to prevent the integrated acting part 5-2 from moving away from the supporting boss 1-2 on its own, thereby further improving the stability of the shelf; at this time, when the elastic buckling part 5-3 is engaged with the buckling groove 2-4, the integrated swinging member 5 can be fixed to prevent the integrated swinging member 5 from swinging on its own, thereby providing a continuous locking force.

[0043] Furthermore, the elastic buckling portion 5-3 is fixedly connected to the operating portion 5-1.

[0044] Furthermore, a supporting step opening for accommodating the supporting boss 1 - 2 is provided at the bottom of the supporting buckle 2 - 1 .

[0045] Furthermore, the integrated swinging member 5 is an inverted "V" shaped structure, the operating portion and the top of the integrated action portion are connected together, and the top is rotatably connected to the support seat. The advantages are that the structure is compact, the shape matches the support seat, the overall volume is small after installation, and the operation is convenient.
