Abstract

The utility model discloses a translation door for cold storage, which includes a upper guide rail, a lower guide rail, a door panel, first and second rollers, and first, second and third guide wheels, wherein both sides of the upper guide rail door case is provided with a first down-concave and a second down-concave and the first and second down-concaves lean to the door case, the first and second rollers are respectively connected to the first and second hammock seats and located in the upper guide rail, the first and second hammock seats are respectively fixed the upper parts of both sides of the door case, the lower guide rail has the dislocated first and second guide wheels at the door-open side, the distance between the second guide wheel and the door case is farther than the first guide wheel, the lower guide rail has the third guide wheel at the door-close side and the distance between the first guide wheel and the door case equals to the third guide wheel, in order to solve the weak sealing performance of existing translation door for cold storage when closed. The door panel of the utility model can cling to the door case when the door closed, to keep good sealing performance of the cold storage.

Description

Freezer translation door

(1) technical field

The utility model relates to a kind of freezer and moves door.

(2) background technology

Cold-storage door must seal when closing, otherwise can cause leaking of cold air.The freezer of commonly using at present move the door when closing, exist sealing not strong problem.

(3) summary of the invention

The utility model for solve present used freezer move the door when closing, exist sealing not strong problem; The technical scheme that is adopted is: mainly by upper rail, lower guideway, door-plate, first, second wheel, first, two, three guide wheels are formed, be provided with first recessed in upper rail doorframe both sides, second is recessed, and first, two recessed deflection doorframes, first, second wheel is connected to first, two flap seats, and place upper rail respectively, first, two flap seats are individually fixed in the upper end of door-plate both sides, lower guideway is provided with first of dislocation in the side of opening the door, two guide wheels, second guide wheel is far away than first guide wheel from the distance of doorframe, lower guideway is provided with the 3rd guide wheel closing reveal, first, three guide wheels equate from the distance of doorframe, when door is opened, the bottom of door places on second guide wheel, first, second wheel is in the upper rail, and when door was closed, the door-plate bottom placed first, on three guide wheels, first roller be in upper rail first recessed in, second roller be in upper rail second recessed in.

First, second and third guide wheel is tapered, and the door-plate bottom is provided with the groove that is complementary with first, second and third guide wheel.

First, second and third guide wheel is free to rotate, is convenient to moving of door-plate.

Good effect of the present utility model has: owing to be provided with first and second recessed and first and second recessed doorframe that all bends towards at upper rail, therefore when closing, first and second roller be in respectively first and second recessed in, door-plate is moved down and doorframe is close in the upper end; Therefore lower guideway is provided with from doorframe first, three guide wheel nearer than second guide wheel again, and the first, the 3rd guide wheel is in the door-plate lower bottom part groove, when closing, can make the door-plate lower end be close to doorframe.Generally speaking, the utility model is when closing, and door-plate can be close to doorframe, can keep the good sealing of freezer.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

(5) specific embodiment

Embodiment: referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of freezer translation door, mainly by upper rail 10, lower guideway 20, door-plate 30, first, second wheel 11,12, first, two, three guide wheels 21,22,23 form, upper rail 10 is being provided with first near the doorframe both sides, two recessed 13,14, and first, two recessed 13,14 deflection doorframes, first, second wheel 11,12 are connected to first flap seat 40, second flap seat, and place upper rail 10 respectively, first flap seat 40, second flap seat is individually fixed in the upper end of door-plate 30 both sides, be provided with the 3rd guide wheel 23 closing reveal lower guideway 20, lower guideway 20 in the side of opening the door is provided with first, two guide wheels 21,22, second guide wheel 22 is far away than first guide wheel 21 from the distance of doorframe, first, three guide wheels 21,23 distances from doorframe equate, first, two, three guide wheels 21,22,23 is tapered and free to rotate, and door-plate 30 bottoms are provided with and first, two, three guide wheels 21,22,23 grooves that are complementary 31;

When door was opened, the bottom groove 31 of door was on second guide wheel 22, and first and second roller 11,12 is in the upper rail 10;

When door was closed, door-plate 30 bottom grooves 31 were on first and third guide wheel 21,23, first and second roller 11,12 be in upper block respectively first and second in recessed 13,14.

Use of the present utility model is: the fixing doorframe upper edge of upper rail 10, lower guideway 20 is fixed at the bottom of the doorframe.

If be initially opening (first roller 11 can not slip in second recessed 14), at this moment, door-plate 30 lower bottom part grooves 31 are on second guide wheel 22, door-plate 30 is not close to doorframe (can reduce the friction of door-plate 30 sealing strips and doorframe like this when opening, prolong sealing strip service life), slowly mobile door-plate 30, when door-plate 30 during near the sealing doorframe, door-plate 30 lower bottom part grooves 31 break away from second guide wheel 22, touch the 3rd guide wheel 23, door-plate 30 lower bottom part grooves 31 are first, three guide wheels 21,23 effect is descended close and is close to doorframe, simultaneously first roller 11 first recessed 13 neutralizations, second roller 12 that slips into upper rail 10 slip into upper rail 10 second recessed 14 in, the upper end of door-plate 30 is descended and close doorframe, thereby door-plate 30 descends and whole door-plate 30 is close to door-plate 30, therefore the utility model can make door-plate 30 sealing strips be close to doorframe, thereby can prevent effectively that cold air from leaking.

When opening the door, safety push-rod with our company's special use backs down door and (will will make door-plate 30 outer moving to door-plate 30 jackings on the other hand on the one hand when opening the door, therefore need bigger active force), instantaneous what back down, first, second wheel 11,12 shift out first respectively, two recessed 13,14, simultaneously, the 3rd guide wheel 23 enters door-plate 30 bottom grooves 31 away from door-plate 30 bottom grooves 31 and second guide wheel 22, the two ends up and down of door-plate 30 are outer simultaneously to be moved, make whole door-plate 30 outer moving like this, and whole door-plate 30 up moves simultaneously, can reduce door-plate 30 bottom grooves 31 and first like this, two guide wheels 21,22 friction, be convenient to move, then manually actuated, push open like a cork and move door.
