Description

Novel freezer thermal insulating door thermally insulated door

One, affiliated technical field

The utility model is a kind of novel freezer thermal insulating door thermally insulated door that is used for the medium and small fresh-keeping ice house of crops such as fruit, vegetables.

Two, background technology

Along with improving constantly of people's living standard, fruit, Vegetable Preservation technology are constantly promoted, and many medium and small fresh-keeping ice houses have been built up in the crops places of production such as fruit, vegetables thereupon with also suiting measures to local conditions.But the used thermal insulating door thermally insulated door of these fresh-keeping ice houses is gone up the defective of existence because of its design or manufacturing at present, exist following shortcoming: 1, sealing property is bad, has influenced fresh-keeping effect, or has to prolong the available machine time of fresh-keeping refrigeration plant, cause waste, increased fresh-keeping cost.2, because the screwing dress door and can not in freezer, thermal insulating door thermally insulated door be closed tight or open of thermal insulating door thermally insulated door, in the staff enters freezer, during operation, thermal insulating door thermally insulated door can not be closed tight, thereby make in the freezer the gentle variation of temperature bigger, use inconveniently, cause unnecessary waste.

Three, summary of the invention

For overcoming above-mentioned shortcoming, the purpose of this utility model can be closed thermal insulating door thermally insulated door and open in the fresh-keeping ice house for medium and small fresh-keeping ice house provides a kind of, novel overworked storehouse thermal insulating door thermally insulated door easy to use, that the thermal-insulating sealing performance is good.The utility model be on the basis of former thermal insulating door thermally insulated door, carry out improved, it by thermal insulating door thermally insulated door, observe door, thermal insulating door thermally insulated door winding device, observe a winding device etc. and form.One side of thermal insulating door thermally insulated door connects with doorframe by the thermal insulating door thermally insulated door winding device with the doorframe hinge-coupled of fresh-keeping ice house, opposite side, realizes opening the door, closing the door.Thermal insulating door thermally insulated door top is provided with watch window, observes a side and the thermal insulating door thermally insulated door hinge-coupled of door, and opposite side connects with thermal insulating door thermally insulated door by observing the door winding device, and watch window is realized opening and closing.The utility model is to improve thermal insulating door thermally insulated door, the sealing heat-insulating property of observation door when closing, and is provided with heat-insulation layer at thermal insulating door thermally insulated door by on the side of doorframe, leans on the side of thermal insulating door thermally insulated door at the observation door also to be provided with heat-insulation layer.Closing thermal insulating door thermally insulated door, when observing door, under the effect of heat-insulation layer, can improve the sealing heat-insulating property like this.The utility model also improves thermal insulating door thermally insulated door winding device, an observation door winding device, and the thermal insulating door thermally insulated door winding device is made up of outer locking bar, handgrip, outward turning handle, block, interior check lock lever, inward turning handle, handle, pressing plate, locking board etc.The outer locking bar passes thermal insulating door thermally insulated door, also can freely rotate on thermal insulating door thermally insulated door and move.The outer locking bar is equipped with handgrip on an end of thermal insulating door thermally insulated door inboard, the outer locking bar is equipped with the outward turning handle on an end in the thermal insulating door thermally insulated door outside, and the outward turning handle is with outer locking bar thread connection and be pressed on the pressing plate.One end of pressing plate is fixed on the thermal insulating door thermally insulated door, and the other end abuts against on the locking board, and the other end of locking board is fixed on the doorframe; Lockhole on the pressing plate aligns with lockhole on the locking board, is used to lock thermal insulating door thermally insulated door.Block is fixed on the appropriate location of doorframe medial surface.One end of handgrip abuts against on the block, the other end is buckled on the interior check lock lever.One end of interior check lock lever is fixed on the medial surface of thermal insulating door thermally insulated door, the other end is equipped with the inward turning handle, and the inward turning handle is with interior check lock lever thread connection and be pressed on the handgrip, and handle is installed on the appropriate location of thermal insulating door thermally insulated door medial surface.Like this, when thermal insulating door thermally insulated door is closed in the freezer outside, as long as rotate the outward turning handle, by outer locking bar, handgrip, block, wind check lock lever and briquetting, thermal insulating door thermally insulated door is closed tightly on doorframe, and can with outward turning handle not rotate outer locking bar because handgrip is subjected to stopping of block, interior check lock lever this moment, when needs pin thermal insulating door thermally insulated door, can be by the pinning of locking of the lockhole on pressing plate and the locking board.When opening thermal insulating door thermally insulated door, open lock after, only need outward turning just can to open backward rotation.When in the staff enters freezer, carrying out operation and need close thermal insulating door thermally insulated door, by handle thermal insulating door thermally insulated door is closed on doorframe, one end of handgrip is buckled on the interior check lock lever, (this moment, the other end of handgrip also just withstood block), rotate inward turning again being pressed on the handgrip and screwing, just thermal insulating door thermally insulated door can be fastened in freezer, also only need counter-rotating inward turning handle during unlatching, again interior check lock lever is driven in the handgrip derotation, just can in freezer, be opened thermal insulating door thermally insulated door.Observation of the present utility model door winding device by hinged screw rod, revolve handle, buckle etc. and form.One end of buckle is fixed on the observation door, the other end is provided with open slot, and hinged screw rod one end and thermal insulating door thermally insulated door hinge-coupled, the other end are equipped with and revolve handle, revolve an open slot place that connects and be pressed in buckle with hinged screw flight.By screwing handle, the watch window place of door closure at thermal insulating door thermally insulated door will be observed; As long as backward rotation is revolved handle, will revolve again removing buckle from open slot together with hinged screw rod, just can open and observe door.Therefore, the utility model is owing to set up heat-insulation layer in the inboard of thermal insulating door thermally insulated door, observation door, and improved thermal insulating door thermally insulated door and observed winding device on the door, the thermal-insulating sealing performance of thermal insulating door thermally insulated door and observation door is improved, and easy to use, can in freezer, thermal insulating door thermally insulated door be fastened and open, be convenient to the staff and enter the variation of carrying out operation in the freezer and having reduced interior temperature of freezer and atmosphere, avoid unnecessary waste, improved the fresh-keeping and cold storage effect.
