Abstract
The utility model discloses a durability freezer heat preservation door belongs to freezer door field. The two sides of the door body are steel plates, the interior of the door body is filled with heat insulation materials, the connecting piece comprises two connecting plates, the two sides of each connecting plate protrude outwards, the middle of each connecting plate protrudes inwards, dovetail clamping grooves are formed in the protruding positions, a partition strip is arranged between the two connecting plates, the connecting positions of the two ends of the partition strip and the connecting plates are dovetail-shaped recesses, and the two ends of the partition strip are connected with the dovetail clamping grooves protruding in the middle of the connecting plates in a matched mode; the edge of the steel plate protrudes inwards to form a dovetail-shaped recess, and the dovetail-shaped recess is matched and connected with the dovetail clamping grooves protruding from the two sides of the connecting plate. Compared with the traditional bonding mode, the tenon-and-mortise structure is adopted to connect the heat-preservation door plate, so that the strength is high, the impact resistance is high, and the service life is longer; meanwhile, the use of screws is avoided integrally, so that the door plate forms an integral body, and the sealing effect is better.
Description
Technical Field
The utility model relates to a durability freezer heat preservation door belongs to the freezer door field.
Background
At present, the total yield of food industry in China is greatly increased, but a large distance exists between the food industry and social requirements, and a large space is provided for developing quick-frozen food and fresh-keeping food. The existing refrigeration house plate is connected at the joint between plates by a male-female groove splicing mode and polyurethane foaming as an auxiliary mode; the strength of the connecting joint of the cold storage plate is low, the shearing resistance is poor after long-term use, and gaps are easy to appear when vibration occurs, so that cold and hot bridges are formed inside and outside the cold storage, and the energy conservation is not facilitated; meanwhile, the overall strength of the refrigeration house plate is also influenced, and the refrigeration house plate is easy to damage when being collided strongly.
SUMMERY OF THE UTILITY MODEL
Adopt public female groove grafting mode to connect and appear the gap easily between the freezer door plant for solving prior art, and hard freezer board bulk strength, the problem of easy damage that takes place, the utility model provides a durability freezer heat preservation door, concrete technical scheme is as follows:
the two sides of the door body are steel plates, the interior of the door body is filled with heat insulation materials, the connecting piece comprises two connecting plates, the two sides of each connecting plate protrude outwards, the middle of each connecting plate protrudes inwards, dovetail clamping grooves are formed in the protruding positions, a partition strip is arranged between the two connecting plates, the connecting positions of the two ends of the partition strip and the connecting plates are dovetail-shaped recesses, and the two ends of the partition strip are connected with the dovetail clamping grooves protruding in the middle of the connecting plates in a matched mode; the edge of the steel plate protrudes inwards to form a dovetail-shaped recess, and the dovetail-shaped recess is matched and connected with the dovetail clamping grooves protruding from the two sides of the connecting plate.
Gaps between the steel plates and the connecting plates are filled with heat insulation materials, and gaps between the connecting plates and the partition strips are filled with heat insulation materials.
The beneficial effects of the utility model reside in that: compared with the traditional bonding mode, the tenon-and-mortise structure is adopted to connect the heat-preservation door plate, so that the strength is high, the impact resistance is high, and the service life is longer; meanwhile, the use of screws is avoided integrally, so that the door plate forms an integral body, and the sealing effect is better.
