Detailed Description

As shown in fig. 1, the shelf mounting structure provided by the invention is particularly suitable for equipment such as a refrigerator and the like, wherein an inner container of the refrigerator is filled with foaming materials, the shelf mounting structure comprises a refrigerator body 2 and a shelf 3, two sides of the shelf 3 are respectively provided with one support frame 1 mounted on the inner wall of the refrigerator body 2, namely, the shelf 3 is positioned between the two support frames 1, each support frame 1 is provided with at least two support arms 13 arranged at intervals, the support arms 13 are provided with a plurality of convex parts arranged from top to bottom, and the convex parts distributed on different support arms 13 in the support frames 1 and positioned on the same straight line form a support gear 11 together. Support gears 11 on two support frames 1 correspond one-to-one, and support gear 11 on one support frame 1 supports gear 11 protrusion towards the correspondence on another support frame 1, distributes on different support frames 1 and relative convex two support gears 11 as a pair of support gear, and shelf 3 can place on arbitrary a pair of support gear 11.

Taking fig. 2 and 3 as an example, in this embodiment, the shelf 3 is square, the left and right sides of the shelf 3 are respectively provided with a support frame 1, the support frame 1 is rectangular and has two support arms 13 arranged at intervals, the inner wall of the box body 2 is provided with a groove 21 having the same shape as the support frame 1, the support frame 1 is fixed in the groove 21, and the support gear 11 exceeds the groove 21. Because the appearance of support frame 1 is the rectangle, has large tracts of land hollow region in the middle of it, the area that is sheltered from by support frame 1 cover on 2 inner walls of box is very limited, ensures the box heat preservation effect of refrigerator.

In order to effectively position the shelf 3 after being installed, as shown in fig. 3 to 5, at least one bolt 34 and a push-pull mechanism for driving the bolt 34 to extend and retract are provided on the shelf 3, a pin hole 12 for being inserted and connected with the bolt 34 is provided on the support frame 1, and each pair of support gears 11 is correspondingly provided with the pin hole 12, that is, when the shelf 3 is placed on any pair of support gears 11, the bolt 34 can be inserted into the pin hole 12 to complete positioning. More excellent, the bottom both sides of shelf 3 are equipped with locating piece 322, shelf 3 is placed from the opening side of box 2 and is supported on the gear 11, it is foremost to support the one end that is close to the opening side on the gear 11, the in-process is placed to shelf 3, locating piece 322 is when the support gear 11 foremost that shelf 3 placed offsets, bolt 34 aligns rather than the pinhole 12 position that corresponds, easy operation during the installation of shelf 3 does not need the manual work to align bolt 34 and pinhole 12, reduce the installation degree of difficulty.

Specifically, as shown in fig. 5, the push-pull mechanism includes: elastic component 33, main push rod 35 and adapter rod 36, the one end of elastic component 33 is fixed on shelf 3, the other end is fixed on main push rod 35, main push rod 35 passes through elastic component 33 and shelf 3 swing joint, every bolt 34 all articulates an adapter rod 36, the other end of adapter rod 36 articulates on main push rod 35, adapter rod 36 follows the swing when external force promotes main push rod 35 motion, drive bolt 34 and inwards retract, the deformation of bolt 34 from the in-process elastic component 33 of the inward retraction of state that stretches out increases gradually, when external force loosens main push rod 35, the restoring force of elastic component 33 acts on main push rod 35, outwards ejecting bolt 34.

As shown in fig. 6, the shelf 3 is provided with a mounting groove 311 for accommodating the latch 34 and the push-pull mechanism, the mounting groove 311 includes a first groove portion, a second groove portion, and a third groove portion connected between the first groove portion and the second groove portion, the latch 34 moves linearly in the first groove portion, the main push rod 35 moves linearly in the second groove portion, and the changeover lever 36 swings in the third groove portion. The movement of the plug pin 34 and the push-pull mechanism is limited through the mounting groove 311, and the operation reliability of the push-pull mechanism is guaranteed.

Taking fig. 5 as an example, in this embodiment, the shelf 3 is provided with more than two bolts 34, the bolts 34 are distributed on two sides of the main push rod 35, two bolts 34 are respectively provided on two sides of the main push rod 35, and two pin holes 12 are correspondingly provided above each support gear 11 on the support frame 1 on the same side. The moving direction of the main push rod 35 is perpendicular to the moving direction of the bolts 34, the main push rod 35 moves along the width direction of the shelf 3, the bolts 34 move along the length direction of the shelf 3, the elastic piece 33 is located at one end of the main push rod 35 and is located on the same straight line with the main push rod 35, the elastic piece 33 adopts an elastic rope or a spring, the main push rod 35 drives the bolts 34 on two sides to retract inwards synchronously when external force pushes the main push rod 35, and when the external force loosens the main push rod 35, the main push rod 35 ejects the bolts 34 on two sides outwards synchronously.

In order to facilitate the processing of the shelf, as shown in fig. 6 and 7, the shelf 3 is formed by overlapping and fixing a first partition plate 31 and a second partition plate 32, a mounting groove 311 is formed on one surface of the first partition plate 31 facing the second partition plate 32, and the second partition plate 32 covers the mounting groove 311. Further, the main push rod 35 is provided with a handle 351, the second partition plate 32 is provided with a through hole 321 allowing the handle 351 to move, and the handle 351 is located in the through hole 321 or extends out of the through hole 321, so that the manual operation of a user is facilitated.

When the shelf mounting structure is used, a main push rod 35, an adapter rod 36 and a bolt 34 in a push rod mechanism are firstly assembled, the assembled push rod mechanism is placed in a mounting groove 311 at the bottom of a first partition plate 31 after being assembled, then an elastic rope 33 between the first partition plate 31 and the main push rod 35 is mounted, then a second partition plate 32 is fixedly connected with the first partition plate 31, and at the moment, the shelf 3 is assembled. Then, the two support frames 1 are fixedly arranged in the rectangular grooves 21 at the left side and the right side of the box body 2, the handle 351 on the main push rod 35 is slid to drive the main push rod 35 to move along the width direction of the shelf 3, the bolt 34 is driven to slide along the length direction of the shelf through the transmission action of the adapter rod 36, the bolt 34 is inwardly contracted into the shelf 1, the contraction state of the bolt 34 is kept, the shelf 1 is horizontally placed on any pair of supporting gears 11 and is pushed until the positioning block 322 is just contacted with the foremost end of the supporting gears 11, the handle 351 is loosened, each main push rod automatically resets under the elastic action of the elastic element 33, the bolt 34 extends out of the edge of the shelf 3, the extending end is inserted into the pin hole 12, at the moment, the installation operation of the shelf 3 is completed, the handle 351 is slid again to enable the bolt 34 to contract into the shelf 3, the shelf 3 can be taken out, the installation height of the shelf 3 can be adjusted, all arrange bulge and pinhole 12 in on the support frame 1 of addding, can eliminate the direct contact of shelf 3 and box inner wall, reduce the possibility of hitting concave box inner wall when installing, prolong the life of refrigerator to addding support frame 1 and can making the inner bag structure of box 2 simplify more, need not to set up the protruding position of thin and narrow, only the recess 21 of whole broad is favorable to improving the foaming quality, reduces the not enough possibility of foaming.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
