Description

Technical Field

[0001] The utility model relates to a device for correcting the sag of the door of a flat quick-freezing machine, belonging to the field of flat quick-freezing machines. Background Technique

[0002] Currently, the doors of flat quick-freezing machines are relatively heavy, and the method of connecting multiple doors is mostly adopted, that is, one door is installed on the library body with hinges, and the remaining multiple doors are connected with ordinary hinges. For large flat quick-freezing machines or those with a large inventory, the overall length of the library door is relatively long. Affected by gravity during long-term use, the library door is prone to tilt and sag. This not only affects the overall aesthetics of the quick-freezing machine, but also easily causes damage to the door body, poor sealing, and cold loss during long-term tilting and sagging. This situation will affect the overall refrigeration effect of the quick-freezing machine, unable to quickly freeze goods, resulting in waste of some cold energy, lengthening of production working hours, increased energy consumption of the whole machine, and reduced refrigeration efficiency. Summary of the Invention

[0003] According to the problems described in the background, the problem to be solved by the utility model is: to provide a device for correcting the sag of the door of a flat quick-freezing machine, through which the tilt and sag of the door can be corrected.

[0004] To achieve the above purpose, the utility model provides the following technical solution: to provide a device for correcting the sag of the door of a flat quick-freezing machine, including a library body, hinges, a library body base, and a library door. It is characterized in that it further includes lifting rollers, a lifting base, a fall-preventing hinge one, and a fall-preventing hinge two. The library body is located on the library body base, and the hinges connect the library door and the library body. The lifting rollers are installed at the lower left end of the main library door, and the lifting base is installed on the library body base and is on the same vertical line as the lifting rollers. When closing the library door, the lifting rollers rise due to the lifting base, and then the library door also rises accordingly, achieving the leveling of the library door. The fall-preventing hinge one and the fall-preventing hinge two respectively connect two adjacent library doors. Through the special design of the hinges, it is also possible to prevent the sag of the library door when opening the door to pick up items, and it can also prevent the collision of the library doors.

[0005] The fall-preventing hinge one includes a left hinge bottom plate, left hinge bolt holes, a connecting rod, a left load-bearing block, and left reinforcing ribs. The connecting rod is located at the center of the right side of the left hinge bottom plate. The left hinge bolt holes are opened on the left hinge bottom plate, and there are multiple of them to enhance the bearing capacity of the hinge. The left load-bearing blocks are evenly distributed on the front end face of the left hinge bottom plate, and the left reinforcing ribs connect each left load-bearing block to the left hinge bottom plate to enhance the load-bearing strength of the load-bearing blocks.

[0006] The anti-falling hinge two includes a right hinge base plate, right hinge bolts, an upper connecting rod, a lower connecting rod, a first right load-bearing block, a second right load-bearing block, a third right load-bearing block, and right reinforcing ribs. The upper connecting rod and the lower connecting rod are respectively located at the upper and lower top positions on the left side of the right hinge base plate, and the upper connecting rod and the lower connecting rod are flush with the upper and lower end faces of the right hinge base plate. The right hinge bolts are provided on the right hinge base plate at multiple positions to enhance the bearing capacity of the hinge. The first right load-bearing block is located at the upper and lower ends of the front face of the right hinge base plate and is flush. The second right load-bearing block is located on the front face of the right hinge base plate and between the first right load-bearing blocks. The third right load-bearing block is located on the front face of the right hinge base plate and in the middle. The right reinforcing ribs connect each of the first right load-bearing block, the second right load-bearing block, and the third right load-bearing block to the right hinge base plate to enhance the load-bearing strength of the load-bearing blocks.

[0007] The lifting roller includes a roller top plate, top plate bolt holes, roller side plates, a roller, a roller rod, and a bearing. The top plate bolt holes are provided around the roller top plate, and it can be installed under the warehouse door through bolts. The roller side plates are located on both sides of the roller top plate. The roller is located between the two roller side plates. The bearing is located at the center of the roller. The roller rod connects the two roller side plates and passes through the bearing at the center of the roller to enable the roller to rotate itself.

[0008] The lifting base includes base side plates and a base main body. The base side plates are provided on both sides of the base main body, which can better match the base of the warehouse body and is convenient for installation.

[0009] The front end of the base main body is in the shape of an inclined ladder. In this way, when closing the warehouse door, the lifting roller can rise along the inclined ladder of the lifting base, and then the warehouse door will also rise together to achieve the leveling of the warehouse door and prevent it from falling.

[0010] The front face of the left load-bearing block is provided with a chamfer, and the inclination angle of the chamfer is the same as that of the right reinforcing rib. In this way, even when the warehouse door has fallen partially due to gravity when opening, it can still be raised to be level due to the chamfer. Moreover, after the inclination angle of the chamfer is the same as that of the reinforcing rib, when the warehouse door is opened until the chamfer and the reinforcing rib come into contact, it can stop and prevent the warehouse doors from colliding.

[0011] The front faces of the first right load-bearing block, the second right load-bearing block, and the third right load-bearing block are all provided with chamfers, and the inclination angle of the chamfers is the same as that of the left reinforcing rib. In this way, even when the warehouse door has fallen partially due to gravity when opening, it can still be raised to be level due to the chamfers. Moreover, after the inclination angle of the chamfers is the same as that of the reinforcing rib, when the warehouse door is opened until the chamfers and the reinforcing rib come into contact, it can stop and prevent the warehouse doors from colliding.

[0012] Working principle: When the library door has sagged after long-term use, the overall library door is inclined. Install lifting rollers under the library door, and then install the lifting base on the library body base under the lifting rollers. When the library door is closed, the lifting rollers under the library door climb up along the slope when they encounter the slope of the lifting base. During the process of the lifting rollers climbing the slope, the library door is also lifted upward. Finally, the lifting rollers finish climbing the slope and reach the horizontal position of the bottom plate. At this time, the library door has been closed and is overall flush, without inclination or sag; when opening the library door, the load-bearing blocks between the two anti-falling hinges cooperate with each other alternately, so that the library door will not sag in the open state and can also prevent collisions.

[0013] The beneficial effects of the present utility model are:

[0014] 1. By adding lifting rollers and a lifting base, the library door will not tilt and sag when closed, and can be corrected.

[0015] 2. Installing lifting rollers and a lifting base on newly produced plate quick-freezers can prevent the library door from tilting and sagging.

[0016] 3. The anti-falling hinges can correct the sagging position of adjacent doors through the hinges when taking items while opening the door, prevent sagging and inclination, and can also prevent collisions between library doors.

[0017] 4. This design has a simple structure, is easy to install, is overall beautiful, is not prone to drawbacks such as door body damage, poor sealing, and cold loss, can also enhance the refrigeration effect, quickly freeze goods, reduce cold waste, shorten the production working time, reduce the overall energy consumption of the machine, and improve the refrigeration efficiency.
