Embodiment in type, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of the utility model protection.
Embodiment
Referring to Fig. 1, present embodiment discloses a kind of freezer slide-lifting door, including a pair of opposing door guide rail 3, by
Movable doorboard 1, door head motor 4, synchronizing shaft, sprocket wheel 5 and transmission that horizontally disposed door horizontal stripe 2 is linked in vertical direction
Chain；Synchronizing shaft is horizontally disposed and rotation is installed on the inside of lintel, and is connected with door head motor 4；The two ends transmission of synchronizing shaft
It is connected with sprocket wheel 5, sprocket wheel 5 and is wrapped with driving-chain, driving-chain is connected with the bottom of movable doorboard 1, passes through when rotating sprocket wheel 5
Driving-chain, which is rotated, drives movable doorboard 1 to lift；The both sides slide-and-guide of movable doorboard 1 is connected to a guide rail 3, and movable doorboard 1
Every door horizontal stripe 2 between be equipped with sealing joint strip；Sealing joint strip is provided between movable doorboard 1 and door guide rail 3.
Slide-lifting door is designed as a result of lifting, and movable doorboard 1 is directly raised to the headroom being difficult by during enabling,
Utilization to space is more reasonable.And for freezer product, the utility model is even more to further increase sealing, all horizontal strokes
All sealed between bar 2 between movable doorboard 1 and door guide rail 3 with sealing joint strip, outside heat is difficult to enter freezer
Inside, maintains the constant temperature of cool house internal, saves the refrigeration energy.
Preferably, the movable doorboard 1 is provided with steel band or steel chain along lifting direction, every close-packed arrays of door horizontal stripe 2 are consolidated
Due on steel band or steel chain.The door horizontal stripe 2 being chained up can be one by one hinged by hinge, but so obviously make installation more
Plus it is cumbersome, and the installation of the sealing joint strip between a horizontal stripe 2 is hindered to a certain extent.Carried out by steel band or steel chain
Link can be prevented effectively from this problem, and structure is also simpler.
Due to there is a guide rail 3 to undertake guide effect, naturally It is not necessary to be driven to the side of a whole movable doorboard 1
It is dynamic, it is only necessary to the lifting for being just capable of the whole movable doorboard 1 of smooth drive is driven to a point.Therefore, preferably, described
The two bottom sides of movable doorboard 1 are respectively equipped with a buckle, and the chain link of buckle and driving-chain is rigidly connected.When door head electricity
Machine 4 is rotated, and drives synchronizing shaft to rotate, the also concomitant rotation of sprocket wheel 5, and whole dodge gate can be just driven by driving driving-chain to rotate
Plate 1 rises.And decline action i.e. reversion door head motor 4 of closing the door, reversely drive movable doorboard 1 to decline and close the door.Preferably, described
Door guide rail 3 is located at the following straightened portion of lintel and set, and recurvate arc is provided with lintel, higher than portion more than arc
Divide to put on backward and be obliquely installed.The movable doorboard 1 after rising is not laid flat, can so make full use of movable doorboard 1 from
Help to close the door again.Preferably, the movable doorboard 1 is provided with observation window 6.
Referring to Fig. 2, preferably, the inside of the door guide rail 3 is provided with drop-proof device；The drop-proof device includes
Limiter of speed 7, tensioning wheel 9, steel wire rope 8, torque spring, connecting shaft, swing rod 12, fixed block 10 and jacking block 11；Swing rod 12 is placed in
The both sides of the bottom of movable doorboard 1, its fixing end is rotatably connected with movable doorboard 1, and passes through the downward elastic reset of torque spring；Two
Being rigidly connected between the movable end of root swing rod 12 has connecting shaft；Two fixed blocks 10 are respectively arranged in the two of the bottom of movable doorboard 1
Side, the top of fixed block 10 is wide and narrow base, and side forms an acclivitous inclined-plane；Jacking block 11 is slidably connected to fixed block 10
Inclined-plane on, jacking block 11 is pushed up laterally when moving up and stretch motion, jacking block 11 is connected to the middle part of swing rod 12；Limiter of speed 7 is pacified
Side loaded on lintel, its underface is equiped with tensioning wheel 9, and steel wire rope 8 is wire-wrapped on limiter of speed 7 and tensioning wheel 9, and it passes through
Junction button is connected with connecting shaft.
Drop-proof device is a spotlight of the present utility model.Because movable doorboard 1 can be closed the door by auxiliary of conducting oneself with dignity, then
Once buckle breaks down, whole movable doorboard 1 may produce danger because of deadweight tenesmus.The principle of anti-tenesmus is：Dodge gate
Plate 1 is connected by junction button with steel wire rope 8, drives the synchronous axial system of limiter of speed 7.During normal switch gate action, movable doorboard 1
Lifting action is slower, and the limiter of speed 7 of synchronous axial system is also slow to be rotated, and will not trigger locking action.When movable doorboard 1 is because under deadweight
Pendant, speed is necessarily very fast, and limiter of speed 7 quick rotation has exceeded default velocity amplitude because triggering locking action, and steel wire rope 8 is just not
Can together be loosed with movable doorboard 1, but rapid stop and pull tight swing rod 12 upwards by connecting shaft, overcome during this
The power of torque spring.Swing rod 12 is swung up, and drives the upward sliding of jacking block 11 on both sides, in the presence of fixed block 10, jacking block
11 outside tensioners live door track, and movable doorboard 1 glides, and expanding force is bigger, will be forced to stop to stop.
Drop-proof device is a mechanical safeties, effectively reduces the risk of accident, it is ensured that staff
Life security.
A kind of freezer slide-lifting door that the present embodiment is provided, motor control lifting, automaticity is high, effectively utilizes top
Portion space, and ensure that sealing.It is simple in construction, easily production and maintenance, using conducting oneself with dignity, auxiliary is closed the door, and can save door head electricity
The action energy consumption of machine 4.With drop-proof device, prevent movable doorboard 1 from hindering for some reason and dropping, ensure the life peace of staff
Entirely.
Embodiment described above only expresses several embodiments of the present utility model, and it describes more specific and detailed,
But therefore it can not be interpreted as the limitation to the utility model the scope of the claims.It should be pointed out that for the common of this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
