And, Figure 4 is a partial side cross-sectional view related to the operating lever of the present invention, Figures 5a and 5b is a principal flat cross-sectional view for explaining the opening and closing state of the door of the present invention.

As illustrated in FIG. 1, a slide door opening and closing device 6 for sliding opening and closing of the door 8 is installed at the front of the container body 4 of the freezing container 2. The slide door opening and closing device 6 includes a portion for supporting the door 8, a swing plate 10 for swinging the door 8, and a portion for sliding the door 8.

In the slide door opening and closing device 6 according to an embodiment of the present invention, the components and mechanical parts of the part supporting the door 8 are configured to be installed inside the door 8, and the door 8 is sliding. The components and mechanical parts of the part to be operated are configured to be inserted into the body 4. The built-in and insertion configurations of these components and mechanical parts protect each part from external conditions such as snow exposure and foreign matter penetration, thereby extending the performance of the part and minimizing malfunctions.

Specifically, the upper and lower parts of the door frame 12 is provided with a component for sliding operation, that is, the slide rail 14 and the slide 16, the horizontal guide groove 18 grooved in the front of the container body (4) To be installed in the Therefore, the slide rail 14 and the slide 16 are configured not to protrude onto the front surface of the container body 4 as shown in Figs. 3A and 3B.

Meanwhile, horizontal guide grooves 18 installed at upper and lower portions of the door frame 12 may extend longer than the slide rails 14, as shown in FIGS. 1 and 2, and slide on the slide rails 14. Both swing plates 10 are coupled to both sides of the slide 16 via a connecting piece 17 so as to be rotatable.

3A and 3B, the distal end portion of each swing plate 10 is fastened and fastened to a vertically rotatable shaft rod 21 that is rotatably fitted to the support tube 20 mounted inside the door 8.

Between the two support tubes 20 installed inside the door 8, the support lever 22 for the operating lever is installed to be installed side by side on the two support tubes 20, but is configured to be installed inside the door (8) do. The two support pipes 20 and the support pipes 22 for the operating lever are securely fastened to the door 8 by using a plurality of fixing bars 23 arranged in the horizontal direction.

As shown in FIG. 4, a lock shaft rod 24 having a latch cam 26 is fitted to the actuating lever support tube 22, and the actuating lever 28 exposed to the front side of the door 8 is inserted into the actuating lever support tube 22. By the lock shaft bar 24 is configured to rotate.

With the internal configuration of the door (8) as described above, in the present invention, the components and mechanical parts supporting and coupling the door (8) are installed in the interior of the door (8).

On the other hand, in the upper and lower frames 12a and 12b in the door frame 12, insertion grooves 30 are formed, and the door 8 is supported by the closing swing of the swing plate 10 when the door 8 is closed. The exposed portion 20a of the support tube 20 is configured to be formed at a position where it can be inserted.

In addition, since the latch holder 32 is installed at the bottom and top of the upper and lower frames 12a and 12b, the latch cam 26 of the operation lever 28 is latched to the latch holder 32 during the closing operation of the door. do.

The operation principle of the slide door opening and closing device 6 of the refrigerating container 2 having the above-described structure will be described in detail as follows.

3A and 5A, when the door 8 or the operating lever 28 is pushed in the door closing direction (right in FIG. 1) to close the open door 8, the slide 16 connected to the door 8 ) Slides the door 8 along the slide rail 14, and the slide 16, which is being slid, hits the stopper at one end of the slide rail 14 at its swing force. Will make the swing swing. Accordingly, the exposed portion 20a of the support tube 20 supporting the door 8 is inserted into the insertion groove 30 formed in the upper and lower frames 12a and 12b, and the latch cam 26 is also latched holder. It is inserted into the groove part of (32).

At this time, the door 8 is completely closed, and the front of the door 8 and the front of the door frame 12 maintain the same height. In addition, when the door is completely closed, the swing plate 10 of the door 8 is also folded in the horizontal guide groove 18, but is folded while wrapping the slide 16 and the slide rail 14, the swing plate 10 Even it does not protrude out of the body.

In this state, when the user pushes the operation lever 28, the latch cam 26 is rotated and locked in the groove of the latch holder 32, thereby making the door 8 locked.

3b and 5b show that the door 8 is closed and locked.

On the other hand, when the user wants to open the door 8 in the locked state by closing, pull the operation lever 28 and then push in the door opening direction (left in Fig. 1).

That is, when the operation lever 28 is pulled, the latch cam 26 fixed to the groove of the latch holder 32 is released and the exposed portion 20a of the support tube 20 connected to the swing plate 10 is pulled out. ) Allows it to exit from the insertion groove 30 of the upper and lower frames 12a and 12b. In this state, when the door 8 is pushed in the door opening direction, the door 16 is opened because the slide 16 slides along the slide rail 14 by the force.

6 and 7 illustrate another embodiment of the present invention. FIG. 6 is a front view, and FIG. 7 is a partial cross-sectional side view of the main part.

In another embodiment of the present invention shown in Figures 6 and 7 omit the support shaft 22 for the operating lever in which the locking shaft rod 24 installed in the interior of the door 8 is rotatably fitted in FIGS. The invention is implemented to act as a latch.

In another embodiment of the present invention, as shown in Figures 6 and 7, the support pipe 20 is installed on the vertical rotary shaft rod 21 is rotatably fitted with a latch cam (26A) and the upper and lower frames of the corresponding door frame 12 ( The latch holder 32A is attached to and configured at 12a and 12b, respectively. At this time, the vertical rotating shaft rod 21 is axially connected to the front end of the swing plate 10 but configured to rotate freely, the operating lever 28 is partially exposed to the front of the door (8) to pull and push the user Based on the configuration is configured to rotate the vertical rod shaft 21.

With this structure, the vertical rotation shaft rod 21 rotatably fitted to the support tube 20 supporting the door 8 by the closing swing of the swing plate 10 during the closing operation of the door 8 is a vertical frame ( The latch cam 26A is latched into the latch holder 32A located at the bottom and the top of the upper and lower frames 12a and 12b while being inserted into the insertion groove 30 of the 12a and 12b.

In general, when the refrigerated container is manufactured to be loaded on a vehicle, the volume ratio in the freezing container body is determined in consideration of external protrusion parts, and the freezing container 2 according to the embodiment of the present invention includes a slide door opening and closing device 6. Parts or components are inserted into the door or the main body, which makes it possible to secure more volume ratio.

As described above, in the present invention, the sliding door opening and closing device of the refrigerated container is safer from external impact, and since each part is not exposed from the container body and the door, there is no fear of infiltration of moisture or various foreign substances, and flexible operation is possible at all times. It also has the advantage of having a beautiful appearance. In addition, due to the structure that does not protrude to the outside of the container, the width of the container can be as wide as that of the existing protrusion, so that the container content can be made larger, thereby increasing the loading efficiency.
