In order to enhance the strength of the guide body for restraining the moving body, as shown in fig. 3, each of the first guide body 110 and the second guide body 120 has upper and lower sidewalls to restrain the first moving body 210 and the second moving body 310 in the vertical direction and prevent the first moving body 210 and the second moving body 310 from moving up and down.

It can be understood that the length of the first slit 112 matches the first moving body 210, the length of the second slit 122 matches the second moving body 310, and the first moving body 210 and the second moving body 310 are configured as rollers, so that the opening lengths of the first slit 112 and the second slit 122 can be reduced, and the limiting effect of the first guide body 110 on the first moving body 210 and the second guide body 120 on the second moving body 310 can be improved. The number of the first notches 112 is the same as that of the first moving bodies 210, the number of the second notches 122 is the same as that of the second moving bodies 310, as shown in fig. 3, one first notch 112 and one first moving body 210 are provided, two second notches 122 and two second moving bodies 310 are provided, and the distance between the two second moving bodies 310 is the same as that between the two second notches 122.

In addition, one of the first slits 112 is disposed at the rear side of the first guide groove 111 and located at the deepest part of the first guide groove 111, and one of the second slits 122 is disposed at the rear side of the second guide groove 121 and located at the deepest part of the second guide groove 121. The positions of the first notch 112 and the second notch 122 are set to indicate the time when the front shelf 200 and the rear shelf 300 are separated from the support 100, when the front shelf 200 and the rear shelf 300 slide to the deepest position, the first moving body 210 faces the first notch 112, the second moving body 310 faces the second notch 122, the first moving body 210 is conveniently positioned to the first notch 112, the second moving body 310 is positioned to the second notch 122, and the support 100 can be separated by lifting the front shelf 200 and the rear shelf 300 at the moment.

As shown in fig. 3, two second breaks 122 are provided, and the second break 122 at the rear side is just communicated with the deepest part of the second guide groove 121; the first slit 112 is provided with one, and the first slit 112 is communicated with the deepest part of the first guide groove 111.

It is contemplated that, in order to facilitate the first moving body 210 to enter and exit the first slit 112 and the second moving body 310 to enter and exit the second slit 122, the opening positions of the upper side and the lower side of the first slit 112 and the second slit 122 are set to be flared, so as to improve the convenience of the front shelf 200 and the rear shelf 300 to be installed in or removed from the support 100.

In order to prevent the front shelf 200 and the rear shelf 300 from moving to the deepest position and retreating, the first guide groove 111 and the second guide groove 121 are slightly inclined downward in the front-to-rear direction, so that the front shelf 200 and the rear shelf 300 can stably rest at the deepest position of the guide grooves under the action of gravity.

In addition, the limiting structures are arranged in the depths of the first guide groove 111 and the second guide groove 121, so that the limiting effect on the front shelf 200 and the rear shelf 300 is achieved. Specifically, as shown in fig. 3, a first limiting groove 113 is disposed at the rear side of the first guide body 110, the first limiting groove 113 is communicated with the first guide groove 111, the first limiting groove 113 is recessed downward relative to the lower wall surface of the first guide groove 111, and when the first moving body 210 moves backward along the first guide groove 111 into the first limiting groove 113, the first limiting groove 113 limits the first moving body 210 in the forward and backward directions, so as to prevent the first moving body 210 from moving backward; the rear side of the second guide body 120 is provided with a second limiting groove 123, the second limiting groove 123 is communicated with the second guide groove 121, the second limiting groove 123 is recessed downward relative to the lower wall surface of the second guide groove 121, and when the second moving body 310 moves backward along the second guide groove 121 to the second limiting groove 123, the second limiting groove 123 limits the second moving body 310 in the front-rear direction, so that the second moving body 310 is prevented from moving backward.

It can be understood that the first limiting groove 113 is communicated with the deepest part of the first guide groove 111 in the front-back direction, and the first limiting groove 113 is located just below the first notch 112, so that the first guide body 110 has both the functions of limiting the first moving body 210 at the deepest part and indicating the timing of detachment; similarly, the second limiting groove 123 is communicated with the deepest part of the second guide groove 121 in the front-rear direction, and the second limiting groove 123 is located just below the second notch 122, so that the second guide body 120 has both the functions of limiting the second moving body 310 at the deepest part and indicating the timing of detachment.

In addition, in order to make the limiting groove fit the shape of the moving body and facilitate the moving body to slide into or out of the limiting groove, the first limiting groove 113 and the second limiting groove 123 may be set to be arc-shaped.

Since the first moving body 210 is separated from the front side of the support 100, as shown in fig. 2, the first moving body 210 is provided with one and is disposed near the front side of the front shelf 200 so that the first moving body 210 slides out from the front side of the support 100, and compared to the case where the first moving body 210 is provided in plurality and is disposed at the rear side of the front shelf 200, the risk of interference between the first moving body 210 and the support 100 can be reduced.

Further, in order to provide stable support for the support 100 to the front shelf 200, referring to fig. 2 and 3, the support 100 is further provided with a third guide 130 to assist in supporting the front shelf 200 of the first guide 110.

It can be understood that when the first moving body 210 slides along the first guide groove 111, the protrusion 220 slides along the third guide groove 131 synchronously, the lower side wall of the third guide body 130 supports the protrusion 220, the lower side wall of the first guide groove 111 supports the first moving body 210, and the support 100 supports the front shelf 200 through two support points, so that the movement of the front shelf 200 is more stable.

Also, the protrusion 220 is provided in a cylindrical shape to reduce friction between the protrusion 220 and the third guide groove 131; or the protrusion 220 is provided as a roller to make the movement of the protrusion 220 in the third guide groove 131 smoother.

It can be understood that when the first moving body 210 moves to the first opening 112 and the second moving body 310 moves to the second opening 122, the protrusion 220 just moves to the third opening 132, the front shelf 200 and the rear shelf 300 are lifted upwards, and the protrusion 220 is separated from the support 100 from the third opening 132; similarly, the third notch 132 may be disposed at the deepest part of the third guide groove 131 to indicate the timing of the detachment of the protrusion 220.

A notch may be formed at a front side of the third guide body 130, the notch communicates with the third guide groove 131, when the protrusion 220 moves forward, the protrusion 220 may be separated from the support 100 from the front side of the third guide groove 131, so that the front shelf 200 may descend relative to the rear shelf 300 after being separated from the front side of the support 100, and after the front shelf 200 is lifted to a horizontal state, the protrusion 220 may be retracted into the third guide groove 131 as the first moving body 210 enters the first guide groove 111 and moves along the first guide groove 111.

Alternatively, the third guiding body 130 further includes a guiding opening 133, the guiding opening 133 is communicated with the lower side of the third guiding groove 131 and is located at the front side of the third guiding groove 131, and the guiding opening 133 is used for the protrusion 220 to enter and exit the third guiding groove 131. It should be noted that, after the front shelf 200 is separated from the support 100 from the front side, the front shelf 200 is lowered relative to the rear shelf 300, and the front shelf 200 is located below the support 100, and the guide opening 133 is disposed at the lower side of the third guide body 130, so that the protrusion 220 can enter the third guide groove 131 from the lower side of the third guide body 130 when the front shelf 200 is raised.

It will be appreciated that, in order to facilitate the front shelf 200 to be detached from the support 100 from the front side of the support 100, the first guide body 110 is further provided with a fourth notch 114, and the fourth notch 114 communicates with the front side of the first guide groove 111. When the front shelf 200 is pulled forward, the first mobile body 210 moves to the position of the fourth gap 114 along the first guide groove 111, and disengages from the support member 100 at the fourth gap 114.

After the front shelf 200 is separated from the support member 100 from the fourth opening 114, the front shelf 200 rotates around the connection part of the rotating rod 410 and the rear shelf 300, the protruding part 220 rotates synchronously with the front shelf 200, and the guide opening 133 can be arc-shaped to conform to the motion rule of the front shelf 200 and guide the movement of the protruding part 220; in addition, the width of the guide opening 133 may be greater than the width of the protrusion 220, so as to facilitate the processing of the support 100 at the guide opening 133, and to avoid the protrusion 220 from entering and exiting the third guide groove 131 by the guide opening 133.

The sliding process of the front shelf 200 and the rear shelf 300 is: referring to fig. 4, in an initial state, the front shelf 200 and the rear shelf 300 are both located at the deepest position, the first moving body 210 is limited in the first limiting groove 113, and the second moving body 310 is limited in the second limiting groove 123, so that the front shelf 200 and the rear shelf 300 can be taken out of the refrigerator by lifting the front shelf 200 and the rear shelf 300.

In an initial state, the front shelf 200 is pulled forward, the first moving body 210 slides out of the first limiting groove 113, enters the first guide groove 111, and moves forward along the first guide groove 111, meanwhile, the second moving body 310 slides out of the second limiting groove 123, enters the second guide groove 121, and moves forward along the second guide groove 121, the protrusion 220 moves forward along the third guide groove 131, as shown in fig. 5, when the front shelf 200 and the rear shelf 300 move to the foremost side, the first moving body 210 is separated from the support 100 at the fourth notch 114, the second moving body 310 is located at the foremost side of the first guide groove 111, and the protrusion 220 is located at the foremost side of the third guide groove 131; as shown in fig. 6, the front shelf 200 is lowered with respect to the rear shelf 300, and the projection 220 is lowered simultaneously with the front shelf 200 and is separated from the support 100 from the guide opening 133.

It should be noted that when the guide bodies protrude and the moving bodies are recessed, the first moving body 210 is provided with a guide groove for the first guide body 110 to slide back and forth, the second moving body 310 is provided with a guide groove for the second guide body 120 to move back and forth, the first moving body 210 and the second moving body 310 are provided with a notch, the notch is located at the lower side of the first moving body 210 and the second moving body 310, the front shelf 200 and the rear shelf 300 are lifted upwards, and similarly, the first moving body 210 can be separated from the notch and the second moving body 310 can be separated from the support 100 at the same time. A notch for disengaging the first guide body 110 is formed in the rear side of the first mobile body 210, and when the front shelf 200 is pulled forward, the first guide body 110 disengages from the first mobile body 210 from the notch, so that the front shelf 200 disengages from the support member 100, and the front shelf 200 can be lifted relative to the rear shelf 300.

The first mounting bodies 241 and the second mounting bodies 331 are used for connecting the rotating rods 410, two ends of the rotating rods 410 are respectively rotatably connected with the first mounting bodies 241 and the second mounting bodies 331, and the distance between every two adjacent first mounting bodies 241 on the front frame side piece 240 in the front-back direction is equal to the distance between every two adjacent second mounting bodies 331 on the rear frame side piece connected with the corresponding rotating rods 410 in the front-back direction, so that the two adjacent rotating rods 410 are parallel to each other.

The first mounting body 241 and the second mounting body 331 may be provided in plural numbers, the number of the first mounting body 241 and the second mounting body 331 corresponds to the number of the swing rods 410, and the swing rods 410 other than the parallel four-bar linkage may be provided inside or outside the parallel four-bar linkage and be parallel to the swing rods 410 in the parallel four-bar linkage.

As shown in fig. 1, the lever group 400 includes two levers 410, the front frame side member 240 includes two first mounting bodies 241, the rear frame side member 330 includes two second mounting bodies 331, both ends of one lever 410 of the parallel four-bar linkage are rotatably connected to the first mounting body 241 located at the front side of the front shelf 230 and the second mounting body 331 located at the front side of the rear shelf 320, respectively, and both ends of the other lever 410 are rotatably connected to the first mounting body 241 located at the rear side of the front shelf 230 and the second mounting body 331 located at the front side of the rear shelf 320, respectively.

In order to prevent the rotation rods 410 at the front side and the rear side from interfering with each other when the front shelf 230 is lifted, the two first installation bodies 241 are staggered from each other in the direction of the front shelf 230 toward the support 100, and the two second installation bodies 331 are staggered from each other in the direction of the rear shelf 320 toward the support 100; taking the parallel four-bar linkage mechanism located at one side of the front shelf 200 or the rear shelf 300 as an example, in the parallel four-bar linkage mechanism, two ends of one rotating rod 410 are respectively connected to the first installation body 241 and the second installation body 331 close to the support 100, and two ends of the other rotating rod 410 are respectively connected to the first installation body 241 and the second installation body 331 far away from the support 100, so that the two rotating rods 410 are mutually staggered in the direction towards the support 100, and projections of the two rotating rods 410 on a horizontal plane have a certain distance and are mutually parallel.

The front frame side member 240 further includes a front side strip 242 and a rotating rod 410 connected to the first mounting body 241 close to the support member 100, when the front shelf 200 descends, a part of the front shelf 230 descends to the bottom of the rotating rod 410, in order to prevent the rotating rod 410 from influencing the descending of the front shelf 200, a clearance gap 2421 is provided on one side of the front side strip 242 facing the support member 100, and the clearance gap 2421 can avoid the rotating rod 410 close to the support member 100 in the parallel four-bar linkage mechanism, so that the front shelf 200 can descend smoothly.

The first mounting body 241 may be connected to the front side bar 242 by means of bonding or screw fastening, or the first mounting body 241 may be integrally connected to the front side bar 242 and the front frame side member 240 may be integrally formed by means of injection molding or pressing.

Similarly, the rear frame side member 330 further includes a rear side edge strip 332, and the second mounting body 331 is connected to a side of the rear side edge strip 332 facing the support member 100 and located below the rear shelf 320 so as to be coupled with the first mounting body 241 to connect the rotating rod 410. The second attachment body 331 is integrally connected to the rear side rail 332, or assembled to the rear frame side member 330 by means of bonding or screwing.

It should be mentioned that, in order to facilitate the matching between the protruding portion 220 and the third guiding body 130, as shown in fig. 1 and fig. 3, the supporting member 100 further includes a limiting protrusion 140, the limiting protrusion 140 is disposed on two opposite sides of the two supporting members 100, the third guiding body 130 is disposed on the limiting protrusion 140, since the limiting protrusion 140 protrudes toward the front shelf 200, the gap of the avoiding gap 2421 can be compensated, the side of the limiting protrusion 140 facing the front shelf 200 can be attached to the side of the front side edge strip 242 facing the supporting member 100, so that the protruding portion 220 can be inserted into the third guiding groove 131, and the matching between the protruding portion 220 and the third guiding body 130 is achieved.

Furthermore, because the limiting protrusion 140 is protruded, when the rear shelf 300 moves to the foremost side of the second guide groove 121, the front side of the rear shelf 300 abuts against the end surface of the limiting protrusion 140 facing the rear side, and the limiting protrusion 140 can assist the inner wall of the front side of the second guide groove 121 to limit the rear shelf 300. It can be understood that when the front shelf 200 moves to the rearmost side of the first guide groove 111, the rear end surface of the front side edge strip 242 abuts against the front end surface of the limiting protrusion 140, and the limiting protrusion 140 can assist the rear inner wall of the first guide groove 111 to limit the front shelf 200.

In addition, in order to optimize the smooth support of the front shelf 200 by the support member 100, the protrusion 220 should be far away from the first mobile body 210 in the front-rear direction as much as possible, since the protrusion 220 should move backwards to the rearmost side of the third guide slot 131 following the sliding of the first mobile body 210 to complete the placement of the front shelf 200 to the deepest position, or the front shelf 200 should be separated from the support member 100 from the first notch 112, and the second mobile body 310 should move to the foremost side of the second guide slot 121 along the second guide slot 121 to enable the front shelf 200 to be separated from the support member 100 from the fourth notch 114, and therefore, a certain distance should be secured between the rearmost side of the third guide slot 131 and the foremost side of the second guide slot 121; the second installation body 331 connected to the front side of the rear side edge strip 332 has a certain distance from the front side edge piece of the rear shelf 300, and interferes with the limiting protrusion 140 when the rear shelf 300 moves to the foremost side of the second guide groove 121, the front side of the rear side edge strip 332 is provided with an avoiding opening 3321, when the rear shelf 300 moves to the foremost position, the end surface of the avoiding opening 3321 facing the front side abuts against the rear side end surface of the limiting protrusion 140, the avoiding opening 3321 avoids the movement of the rear shelf 300, and the back and forth movement of the rear shelf 300 is limited by the abutting against of the limiting protrusion 140.

As shown in fig. 2 and 4, the first mounting body 241 and/or the second mounting body 331 connected to both ends of the same rotating rod 410 have a stopper 243, and the stopper 243 is used for stopping the rotating rod 410 and limiting the rotation angle of the rotating rod 410.

In the first installation body 241 and the second installation body 331 connected to both ends of the same rotating rod 410, the limiting body 243 can be independently arranged on the first installation body 241 or the second installation body 331, if the limiting body 243 is arranged on the first installation body 241, when the front shelf 200 rotates to the limit position, the limiting body 243 is abutted against the front shelf 200, and the front shelf 200 is supported by the limiting body 243 and stops at the limit position; if the position-limiting body 243 is disposed on the second mounting body 331, when the front shelf 200 rotates to the limit position, the position-limiting body 243 abuts against the rear shelf 300, and the rotating rod 410 stops rotating under the supporting action of the rear shelf 300, so that the front shelf 200 stops at the limit position.

The first mounting body 241 and the second mounting body 331 connected to both ends of the same rotating rod 410 can be simultaneously provided with the limiting body 243, and when the rotating rod 410 moves to the limit position at the front shelf 200, the rotating rod can be simultaneously abutted against the front shelf 200 and the rear shelf 300, so that the front shelf 200 can be stably suspended at the limit position.

As shown in fig. 1 and 2, in the parallel four-bar linkage mechanism, the first mounting body 241 and the second mounting body 331 connected to the two ends of each rotating rod 410 are respectively provided with a limiting body 243, and the two rotating rods 410 are simultaneously limited by the limiting bodies 243, so that the limiting effect of the limiting bodies 243 on the rotating rods 410 is enhanced.

The limiting body 243 includes a first limiting surface 2431, the first limiting surface 2431 is inclined downward toward the front side of the front shelf 230, the first limiting surface 2431 supports against the rotating rod 410, and when the front shelf 200 descends relative to the rear shelf 300, the front shelf can hover below the rear shelf 300 under the limiting effect of the first limiting surface 2431.

The first and second mounting bodies 241 and 331 are provided with a protrusion toward or away from the side of the support 100, and a first limiting surface 2431 is provided on the protrusion to limit the descending position of the front shelf 200 by the first limiting surface 2431. Alternatively, the first mounting body 241 and the second mounting body 331 are provided with a limit opening 2432, the first limit surface 2431 is one of the wall surfaces forming the limit opening 2432, the end of the rotating rod 410 is inserted into the limit opening 2432, when the rotating rod 410 rotates, the part accommodated in the limit opening 2432 moves in the limit opening 2432, and the opening degree of the limit opening 2432 can limit the rotation angle of the rotating rod 410.

It can be understood that, when the first mounting body 241 and the second mounting body 331 are both provided with the limiting bodies 243, the opening direction of the limiting opening 2432 on the first mounting body 241 is set backward, and the opening direction of the limiting opening 2432 on the second mounting body 331 is set forward, so that the two ends of the rotating rod 410 are respectively inserted into the limiting openings 2432 on the first mounting body 241 and the second mounting body 331.

As shown in fig. 6, the first limiting surface 2431 should be located on the upper side of the limiting opening 2432 on the first mounting body 241 and on the lower side of the limiting opening 2432 on the second mounting body 331, so that when the front shelf 200 descends to the limiting position, the upper surface of the rotating rod 410 abuts against the limiting surface 2431 on the first mounting body 241, the lower surface of the rotating rod 410 abuts against the limiting surface 2431 on the second mounting body 331, and the upper and lower sides of the rotating rod 410 are simultaneously limited, so that the front shelf 200 can be stably suspended at the limiting position.
