Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

As shown in fig. 1, the utility model provides a pair of use fixed shelf subassembly's of bolt embodiment, the shelf subassembly include shelf 1 and locate the bolt hole 3 of the left and right sides wall body 2 front end in the case courage and locate the support piece 4 of this both sides wall body rear end. The shelf 1 is composed of a hollow front decoration strip 5, a glass plate 011 and a rear decoration strip 012. The front molding 5 is composed of a front molding case 001 and a front molding cover 009. The left and right sides of the front decorative strip 5 of the shelf 1 are respectively provided with a bolt 007, the two bolts 007 can be simultaneously withdrawn or inserted into the bolt holes 3 of the wall bodies 2 at the left and right sides in the container through a transmission device, and the rear decorative strip 012 of the shelf is matched and fixed with the supporting piece 4. That is, the shelf 1 can be fixed by the engagement of the latch 007 and the latch hole 3, the rear molding 012 and the supporter 4. In this embodiment, the transmission device may be a rack and pinion transmission mechanism, and the pins 007 disposed at the left and right outer ends of the rack in the rack and pinion transmission mechanism may be simultaneously withdrawn from or inserted into the pin holes 3 through the transmission of the rack and pinion.

As shown in fig. 2 and 3, the rack and pinion mechanism includes: locate the gear 002 at middle part in the preceding trim casing 001, locate last bolt connecting rod 004 and lower bolt connecting rod 003 of both sides about this gear 002 in parallel, two bolt connecting rod middle parts be with the rack of gear 002 meshing, the left end of going up bolt connecting rod 004 and bolt connecting rod 003 right-hand member respectively are equipped with a bolt 007 down, and the other end of two bolt connecting rods respectively overlaps and has a reset spring 005 that can make the bolt connecting rod reset. A shift 010 extending out of the front side of the front trim shell 001 is arranged on the bolt connecting rod close to the outer side of the front trim 5, namely the lower bolt connecting rod 003. For the sake of compact structure and reasonable stress, one section of the rod body of the connecting bolt 007 on the two bolt connecting rods is bent towards the gear 002 side (towards the central line) and then stretched horizontally, and the two sections of the rod body are positioned on the same straight line, so that the bolt 007 can be conveniently and accurately withdrawn or inserted into the bolt hole 3. A gear shaft 013 and a gear mounting position 014 are injection-molded on the inner side surface of the front molding shell 001, and the gear 002 is sleeved on the gear shaft 013, so that the gear 002 can be freely rotated by taking the gear shaft 013 as a rotation center. An upper bolt connecting rod guide rail 015 and a lower bolt connecting rod guide rail 015 are injection-molded on the inner side surface of the front decorative strip shell 001 and used for placing an upper bolt connecting rod 004 and a lower bolt connecting rod 003. Wherein, still be equipped with spring spacing step 016. The collar 017 and the spring position limiting step 016 on the latch connecting rod can limit the axial movement of the reset spring 005 sleeved on the latch connecting rod, so that the upper latch connecting rod 004/003 and the lower latch connecting rod 004/003 can move linearly left and right. Importantly, the gear 002 and the two plug pin connecting rods need to be installed in place to ensure that the gear 002 can rotate freely and the plug pin connecting rods can translate along the plug pin connecting rod guide rails 015; the return springs 005 at both ends need to be installed in place to ensure their normal relaxation and compression. In this embodiment, the supporting member is a slot member 4, and the rear trim 012 of the shelf 1 is inserted into the slot of the slot member 4. Other structures can be selected for the transmission device and the supporting piece according to requirements, and the functions can be met.

Please refer to fig. 1 to 3, the present invention also provides a method for controlling a shelf assembly fixed by a pin, comprising the following steps:

the rear trim 012 of the shelf 1 is first inserted into the notch of the notch member 4. The shift lever 010 located at the middle position is shifted to the left, the lower latch connecting rod 003 connected with the shift lever is shifted to the left, and the return spring 005 sleeved on the left side of the shift lever is compressed at the moment. Because the gear 002 is meshed with the racks on the upper and lower bolt connecting rods, the gear 002 rotates clockwise under the drive of the lower bolt connecting rod 003. The upper latch connecting rod 004 is driven to move rightwards through the gear 002, and the return spring 005 sleeved on the right side of the upper latch connecting rod is also compressed at the moment. That is, by controlling the shift 010 to move leftward, the two pin connecting rods are translated toward the middle, and the pins 007 on both sides are retracted toward the inside of the front molding 4. When the bolts 007 at the two ends are used for locking the bolt holes 3 in the wall bodies 2 on the left side and the right side in the upper box liner, the shift 010 is released, the reset spring 005 is decompressed, and under the elastic action of the reset spring 005, the two bolt connecting rods drive the bolts 007 to be outwards ejected and correspondingly inserted into the bolt holes 3 in the wall bodies 2 on the two sides in the box liner, and the two bolt connecting rods return to the initial positions, so that the shelf 1 is locked. When the finger 010 is further moved to the left, the locking is released and the shelf 1 is reversely taken out.

The utility model also provides a refrigerator of having the shelf subassembly that uses the bolt to fix.

The utility model provides an it utilizes mechanical structure gear-rack drive mechanism's drive of shelf, can make the bolt linkage of the trim left and right sides before the shelf, can control it and withdraw from or insert in the bolt hole of the lateral wall body in the case courage. The shelf and the matched ribs thereof can be used for fixing the shelf, the length of the ribs on the refrigerator liner can be reduced, the cost of foam packaging in the refrigerator is reduced, the shelf is suitable for mounting positions of various shelves, and the utilization efficiency of a container space of the refrigerator is improved.

The above embodiments are mainly intended to illustrate the inventive concept, and it should be noted that, for those skilled in the art, a plurality of modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
