Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1, in an embodiment of a shelf assembly fixed by a bolt, the shelf assembly includes a shelf 1, bolt holes 3 arranged at front ends of left and right side wall bodies 2 in a container, and a supporting member 4 arranged at rear ends of the two side wall bodies. The shelf 1 is composed of a hollow front molding 5, a glass plate 011 and a rear molding 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decorative strip 5 of the shelf 1 are respectively provided with a bolt 007, the two bolts 007 can be simultaneously withdrawn or inserted into the bolt holes 3 of the left and right side wall bodies 2 in the container through a transmission device, and the rear decorative strip 012 of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. I.e. the shelf 1 can be fixed by the cooperation of the pins 007 and the pin holes 3, the rear molding 012 and the support 4. In this embodiment, the transmission device may be a rack-and-pinion transmission mechanism, and the pins 007 provided at the left and right outer ends of the rack in the rack-and-pinion transmission mechanism may be simultaneously withdrawn or inserted into the pin holes 3 by the transmission of the rack and pinion.
As shown in fig. 2 and 3, the rack and pinion transmission mechanism includes: the gear 002 at the middle part in locating preceding trim casing 001, upper bolt connecting rod 004 and lower bolt connecting rod 003 of locating the upper and lower both sides of this gear 002 in parallel, two bolt connecting rod middle parts be with gear 002 engaged rack, upper bolt connecting rod 004's left end and lower bolt connecting rod 003 right-hand member respectively are equipped with a bolt 007, and the other end of two bolt connecting rods respectively overlaps has a reset spring 005 that can make bolt connecting rod reset. A shift block 010 extending out of the front side surface of the front decorative strip shell 001 is arranged on the latch connecting rod close to the outer side of the front decorative strip 5, namely, the lower latch connecting rod 003. For compact structure and reasonable atress, the one section body of rod that connects bolt 007 on two bolt connecting rods is all to gear 002 side (to the central line) after bending again flat extension to make two sections body of rods lie in a straight line, so be convenient for bolt 007 accurate withdraw from or insert bolt hole 3. A gear shaft 013 and a gear mounting position 014 are molded on the inner side surface of the front decorative strip shell 001, and the gear 002 is sleeved on the gear shaft 013, so that the gear 002 can be ensured to freely rotate by taking the gear shaft 013 as a rotation center. An upper latch connecting rod guide rail 015 and a lower latch connecting rod guide rail 015 are injection molded on the inner side surface of the front decorative strip shell 001 and are used for placing the upper latch connecting rod 004 and the lower latch connecting rod 003. Wherein, a spring limit step 016 is also arranged. The shaft collar 017 and the spring limit step 016 arranged on the bolt connecting rod can limit the axial movement of the reset spring 005 sleeved on the bolt connecting rod, so that the upper bolt connecting rod 004/003 and the lower bolt connecting rod 004/003 can move linearly leftwards and rightwards. Importantly, the gear 002 and the two bolt connecting rods need to be installed in place so as to ensure that the gear 002 can rotate freely, and the bolt connecting rods can translate along the bolt connecting rod guide rail 015; the return springs 005 at both ends need to be installed in place, ensuring that they can relax and compress normally. In this embodiment, the support is a slot member 4, and the rear molding 012 of the shelf 1 is inserted into the slot of the slot member 4. Other configurations of the transmission and support member may be selected as desired, provided that the functionality is met.
Referring to fig. 1 to 3, the invention also provides a control method for the shelf assembly fixed by the bolt, which comprises the following operation steps:
the rear molding 012 of the shelf 1 is first inserted into the card slot of the card slot member 4. And then the shift block 010 at the middle position is shifted to the left side, so that the lower latch connecting rod 003 connected with the shift block 010 translates to the left side, and the return spring 005 sleeved on the left side of the lower latch connecting rod is compressed. Because the gear 002 is meshed with the racks on the upper and lower latch connecting rods, the gear 002 is driven by the lower latch connecting rod 003 to rotate clockwise. The upper latch connecting rod 004 is driven to translate rightward through the gear 002, and the return spring 005 sleeved on the right side of the upper latch connecting rod is compressed. I.e. by controlling the movement of the shift bar 010 to the left, the two latch bar arrangements translate towards the middle and the latches 007 on both sides retract towards the inside of the front molding 4. When the bolts 007 at the two ends are released to the bolt holes 3 on the left and right side wall bodies 2 in the upper container, 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 on the two side wall bodies 2 in the container, and the two bolt connecting rods return to the initial positions, so that the shelf 1 is locked. When the shifter 010 is shifted to the left again, the lock can be released and the shelf 1 can be taken out reversely.
The invention also provides a refrigerator with the shelf assembly fixed by the bolt.
The shelf provided by the invention can enable the bolts on the left side and the right side of the front decorative strip of the shelf to be linked by utilizing the driving of the gear-rack transmission mechanism with a mechanical structure, and can control the shelf to withdraw from or be inserted into the bolt holes of the inner side wall body of the box liner. The shelf and the ribs matched with the shelf can be used for fixing the shelf, the length of the ribs on the container can be reduced, the cost of foam packaging in the refrigerator is reduced, the refrigerator is suitable for the installation positions of various shelves, and the utilization efficiency of the container space of the refrigerator is improved.
The above-described embodiments are mainly for illustrating the inventive concept, and it should be noted that it is possible for those skilled in the art to make several variations and modifications without departing from the inventive concept, which fall within the scope of the present invention.
