The shelf assembly that this disclosed embodiment provided need not to set up actuating mechanism, and occupation space is little, and is with low costs, and in the in-process of using, the user can operate in order to realize the change to shelf main part height, labour saving and time saving is favorable to promoting the convenience of shelf main part height adjustment.

In some embodiments, as shown in connection with fig. 1-6, the shelf assembly further includes a fixing base 500 and a first elastic member 610. The fixing base 500 is disposed at a first top end 412 and a first bottom end 413 of the supporting frame 410. The fixing seat 500 comprises a connecting section 510 and a stop section 520 which are formed by bending, the connecting section 510 is fixedly connected with the support frame 410 vertically, and the end part of the guide sliding rail 420 is connected with the connecting section 510 in a sliding manner and is positioned between the support frame 410 and the stop section 520. The first elastic member 610 is connected between the stop section 520 and the guide rail 420, and when the shelf main body 100 is switched to the extended position, the first elastic member 610 is compressed, and the sliding portion 300 drives the guide rail 420 to move away from the support frame 410, so that the limiting protrusion 310 is separated from and removed from the limiting groove 411; when the shelf main body 100 is switched to the moving-in position, the first elastic member 610 is reset, and the sliding portion 300 drives the guiding rail 420 to move in a direction approaching to the supporting frame 410, so that the limiting protrusion 310 is clamped into the limiting groove 411.

By the arrangement of the fixing seat 500, the support of the guide sliding rail 420 is facilitated. By arranging the connecting section 510, the end of the guide sliding rail 420 is slidably connected with the connecting section, so that the guide sliding rail 420 can move relative to the support frame 410 under the driving of the sliding part 300. With the guide rail 420 away from the support frame 410, there is a gap between two to facilitate movement of the sliding portion 300. Wherein the end of the guide rail 420 includes a second top end 423 and a second bottom end 424.

By the provision of the stop segment 520, a limitation of the distance of movement of the guide rail 420 is facilitated. Optionally, the stop section 520 is connected perpendicular to the connecting section 510; alternatively, the stop segment 520 is disposed obliquely with respect to the connecting segment 510, and the stop segment and the connecting segment have an included angle ranging from 70 ° to 110 °.

By the arrangement of the first elastic member 610, the first elastic member 610 may be compressed when the shelf main body 100 is switched to the extended position, providing a buffering effect for the movement of the guide rail 420; meanwhile, when the shelf main body 100 is switched to the moving-in position, the first elastic member 610 may rebound to provide an elastic force for the guide rail 420, and the guide rail 420 is beneficial to approach the support frame 410 under the elastic force, so as to facilitate the user to save effort.

Alternatively, the first elastic member 610 is a spring.

In some embodiments, the connection section 510 includes a first side 511 that faces the guide rail 420; the shelf assembly further includes a guide assembly 700 for defining a moving direction of the guide rail 420, and the guide assembly 700 includes a guide chute 710 and a moving block 720. The guide chute 710 is disposed on the first side 511 in a direction away from the support frame 410. The moving block 720 is disposed at the second top end 423 and the second bottom end 424 of the guiding rail 420, and cooperates with the guiding chute 710. During the compression or restoration process of the first elastic member 610, the moving block 720 drives the guide rail 420 to move along the direction defined by the guide chute 710.

Optionally, the direction defined by the guiding chute 710 is the extending direction of the guiding chute 710, and during the compression process of the first elastic member 610, the moving block 720 drives the guiding rail 420 to move along the guiding chute 710 in a direction away from the supporting frame 410; in the process of resetting the first elastic member 610, the moving block 720 drives the guide rail 420 to move along the guide chute 710 in a direction approaching the support frame 410.

Alternatively, as shown in fig. 4 and 5, the moving block 720 may be the second top end 423 and the second bottom end 424 of the guiding rail 420, that is, the second top end 423 and the second bottom end 424 of the guiding rail 420 are configured to be matched with the moving end 730 of the guiding chute 710, so as to be clamped in the guiding chute 710. In this way, the second top end 423 and the second bottom end 424 of the guide rail 420 can move along the corresponding guide chute 710, so as to improve the connection stability between the fixing base 500 and the guide rail 420 and the stability of the guide rail 420 moving along the guide chute 710.

In some embodiments, the shelf assembly further includes a second resilient member 620. The second elastic member 620 is disposed at a side end of the guide rail 420. The first end of the second elastic member 620 is fixedly coupled to the top end of the guide rail 420, and the second end of the second elastic member 620 is fixedly coupled to the sliding portion 300.

Through the arrangement of the second elastic member 620, the second elastic member 620 stretches during the process that the sliding portion 300 drives the cantilever 200 and the shelf main body 100 to move downwards, namely, the bottom end of the guide sliding rail 420, so that a certain buffer force can be exerted, the shelf main body 100 is prevented from suddenly descending due to overlarge force exerted by a user, and the stability of downward movement of the shelf main body 100 is improved; meanwhile, the second elastic member 620 may be contracted in the process that the sliding portion 300 drives the cantilever 200 and the shelf main body 100 to move upward, i.e., to move toward the top end of the guide rail 420, and may play a role in a certain tensile force, so that time and labor are saved, and convenience and safety are achieved.

Alternatively, the second elastic member 620 is just in a natural state when the shelf main body 100 moves up to the extreme position of the guide rail 420, i.e., the uppermost end, along with the sliding portion 300.

Alternatively, the second elastic member 620 is a mainspring.

Alternatively, the height of the shelf main body 100 is adjusted by allowing the sliding main body 320 to penetrate the slideway 422 to be movable up and down along the slideway 422, thereby driving the cantilever 200 and the shelf main body 100 to move up and down.

Optionally, the sliding body 320 is disposed through the sliding way 422, and the sliding side plates 330 are attached to the sliding rail bodies 421 on both sides of the sliding way 422. In this way, when the sliding body 320 moves up and down along the slideway 422, the sliding side plate 330 is attached to the sliding rail body 421 to move up and down, that is, the first contact surface 331 and the second contact surface 4211 are slidably connected, which is favorable for improving the stability of the movement of the sliding portion 300, and preventing the sliding body 320 from falling off from the slideway 422.

In some embodiments, as shown in connection with fig. 4 and 5, the shelf assembly further includes a stop assembly 800 for guiding and positioning the slider 300. The spacing assembly 800 includes a spacing tab 810 and a spacing clip slot 820. The limit bump 810 is disposed on the first contact surface 331. The limiting slot 820 is disposed on the second contact surface 4211, and the limiting slot 820 is matched with the limiting bump 810.

The first contact surface 331 slides up and down with respect to the second contact surface 4211 while the sliding portion 300 moves up and down along the guide rail 420, that is, while the sliding body 320 moves up and down along the slideway 422. Optionally, a plurality of limiting slots 820 are disposed at intervals along the extending direction of the sliding rail body 421, and during the up-and-down movement of the sliding body 320, the limiting protrusions 810 can be clamped into the limiting slots 820 with different heights, so as to fix the sliding portion 300 relative to the guiding sliding rail 420.

Further, in the case of adjusting the shelf main body 100 to a height set by a user, the limit projection 810 is first snapped into the limit clipping groove 820 of a corresponding height to achieve the fixing effect of the sliding portion 300 with respect to the guide rail 420; next, the limiting protrusion 310 on the sliding portion 300 is clamped into the limiting groove 411, so that the fixing effect of the sliding portion 300 relative to the supporting frame 410 can be achieved. In this way, the stopper function of the shelf main body 100 can be improved, and the stability and safety of the shelf main body 100 can be improved.

In some embodiments, the stop assembly 800 further includes a third resilient member. The third elastic member is connected between the limiting bump 810 and the first contact surface 331.

Optionally, the third elastic member is a cylindrical spring, and a cylindrical groove for accommodating the third elastic member is disposed on the first contact surface 331. The third elastic member is beneficial to improving the flexibility of the limit bump 810. Optionally, the third elastic member is integrally disposed in the cylindrical recess, that is, the third elastic member is completely disposed in the cylindrical recess in a natural state and the limit bump 810 is partially disposed in the cylindrical recess, so as to prevent the limit bump 810 from being separated from the cylindrical recess.

Optionally, the third elastic member can provide acoustic feedback for the user, when the limit bump 810 is clamped into the limit slot 820, it is determined by sound that the limit bump 810 is completely clamped into the limit slot 820, and at this time, the limit protrusion 310 of the sliding portion 300 may be further clamped into the limit groove 411, so as to improve the accuracy of the clamping between the sliding portion 300 and the support frame 410.
