The present invention guides the operation (closing or opening) of a sliding door installed in a prefabricated refrigerator/freezer more smoothly, and at the same time is advantageous in preventing wear and noise caused by friction between rollers, as well as safety and failure rate of slide operation based on solid durability It relates to a slide rail frame for prefabricated refrigeration and refrigerator sliding doors that greatly helps in lowering and has more convenient installation and constructability.

Usually, in order to store various agricultural and fishery products, meat, food, etc. in large quantities, the panel assembly type freezer/refrigerator has an electric or manual sliding door that can be opened and closed if the door structure is automated by electric power or the user directly slides the left and right slides by hand. is installed

In addition, the upper and lower slide rails for guiding the smooth left and right movement of the door are respectively configured on the upper and lower parts of the electric or manual sliding door of the refrigeration/refrigerator, and the rail is installed on the door corresponding to each rail. It is common to combine the left and right transfer rollers that open and close the door while moving to roll along.

In addition, in recent sliding doors of panel-assembled freezers and refrigerators, an electric automatic opening and closing system equipped with an electric motor is often built so that the user can open and close the door automatically by the electric motor without manually pushing it.

In order to construct an electric automatic opening/closing system for a sliding door, an electric motor, an electric control box, and numerous electrical connection lines and various parts for power transmission are provided around the sliding door and slide rail.

However, since the existing upper slide rail installed on a sliding door is manufactured focusing only on the left and right transfer rollers configured in the door and the function of guiding the sliding movement of the door in the left and right directions, an electric automatic opening and closing system is installed on the sliding door. Since it is of no help, it takes a lot of time and money to construct the electric automatic opening/closing system, and while the structure of the slide rail itself is very weak and not neat, the frequency of breakdowns during use is high, and the loss from repair is also significant. the current situation.

That is, referring to the already known Patent Registration No. 10-1018297 (automatic and manual sliding door rail structure), “a guide frame for sliding left and right by inserting a roller coupled to the upper part of the door, and the lower part of the guide frame It has a support guide that forms a certain thickness on the surface to support the roller from the lower part, and when the door is opened or closed, the rollers coupled to the left and right ends are located at one side and the center of the left and right ends of the guide frame, respectively, and stop A frame form in which holding grooves are formed in the form of grooves while having an inclined surface in the center and left and right ends of the support guide, and the support guide is formed with an insertion protrusion in the shape of 'ㅗ' at the bottom and an insertion groove into which the insertion protrusion of the support guide can be inserted is formed in the guide frame so as to be slidably coupled, and the inclined surface of the holding groove is coupled through a coupling substrate and fixed together with the support guide. and a stopper for blocking and stopping the rollers on the outside of the holding grooves formed on the left and right ends of the guide frame, and forming an inclined surface to support and seat the inside of the rollers inside the holding grooves. In the automatic and manual sliding door rail structure, a fixing rod connected to a fixing bracket is inserted in the lower portion of the guide frame and further provided with a circular coupler so that it can be fixed to a wall or ceiling.”

However, the prior document does not have any structure that can be helpful when constructing an electric automatic opening/closing system in addition to the role and configuration of guiding the sliding movement of the door in the left and right directions.

In addition, since the structure of fixing the guide frame to the wall or ceiling is made by inserting the fixing rod connected to the fixing bracket at the lower part of the guide frame into the circular coupling hole, it is vulnerable to shaking during use, so the friction load between the rail and the roller is reduced. Not only is it loud and noisy, but it also leads to frequent repairs due to frequent breakage or breakdown during use, and frequent cases where the roller slides from the inside of the guide frame to the outside.

In addition, the corresponding structure of the guide frame, its inner space, and the roller inserted therein of the prior document is extremely unreasonable and highly likely to be separated, especially when the roller descends into the holding groove under the support guide. There are also problems in that there are many parts, the friction load is severe, and noise is generated.
