1 to 5, in summary, when the two-way door opening device 100 of the present invention is used, the user can directly operate the toggle mechanism 3, that is, when the door body 82 of the refrigerator 800 needs to be opened to the left, it can Directly rotate the dial 31 clockwise, and the dial 31 will drive the cam 321 to rotate clockwise, thereby pushing the connecting rod 2 to move to the left. The restriction of the fixing column 813 on this side makes the door body 82 of the refrigerator 800 open from this side. As shown in FIG.

During the above-mentioned process, the blocking mechanism 20 on the left side of the connecting rod 2 further extends into the opening 10 to restrict the fixed column 813 on this side; Under the active force, the two-way door opening device 100 of the present invention can effectively maintain the state of the door opening body adjusted by the user, specifically: when the cam 321 rotates clockwise, it drives the two push rods 332 to move clockwise and along the length of the connecting rod 2. At this time, the first fixed shaft 3321 on the push rod 332 moves counterclockwise and moves toward the direction of the cam 321 in the guide groove 22 at the same time, so that the stretching length of the two extension springs 331 becomes shorter, and in the The state of the cam 321 and the push rod 332 is preserved under the tension of the two extension springs 331; if the cam 321 and the push rod 332 need to be reset, the tension of the extension spring 331 needs to be overcome.

When it is necessary to set the door body 82 of the refrigerator 800 to open to the right, it only needs to operate in reverse according to the above usage method. It can be seen that the two-way door opening device 100 in the present invention can directly adjust the door opening direction of the door body 82 of the refrigerator 800 by adjusting the toggle mechanism 3, which is simple and convenient, and does not require professionals to operate the door body at all, saving time and effort. Moreover, the structure is simple and the cost is low.

Please refer to FIG. 6 which shows another embodiment of the two-way door opener of the present invention, which differs from the two-way door opener in the first embodiment in the toggle mechanism. In this embodiment, the linkage mechanism 42 in the toggle mechanism includes the matching groove 21 formed on the connecting rod 2 and the cam connected to the dial 41 and set in the matching groove 21 421 ; the limiting mechanism 43 is an elastic body connected between the cam 421 and the housing 41 . The elastic body 43 can maintain the state of the cam 42 and further define the position state of the connecting rod 2 . A first positioning shaft 116 protruding from the bottom wall 111 of the shell body 11 is used to fix one end of the elastic body 43 .

The cam 421 is disposed in the fitting groove 21 of the connecting rod 2 and cooperates with the inner wall of the fitting groove 21, so that the cam 421 can resist the inner wall of the fitting groove 21 and drive the connecting rod 2 to move left and right when rotating. The dial 41 is provided with an operating portion 411 facing the outside of the casing 1 and a connecting portion 412 passing through the through hole 115 on the casing body 11 . The cam 421 is provided with a fixing hole 421 fixed to the connecting portion 412 and a second positioning shaft 422 extending along a direction perpendicular to the bottom wall 111 of the housing body 11 . The other end of the elastic body 43 is fixed on the second positioning shaft 422 . The cam 421 is provided with a radially opposite convex portion 423 and a concave portion 424 , and the second positioning shaft 422 is disposed on the convex portion 423 .

As shown in FIG. 1 , in this embodiment, the elastic body 43 is a torsion spring; in the initial state, the convex portion 423 of the cam 42 is set toward the rear wall 114, and at this time, the cam 42 and the first positioning The shafts 116 are located on the same straight line along the width direction of the casing 1 .

In this embodiment, the matching groove 21 on the connecting rod 2 is arranged at the middle position of the connecting rod 2 , indeed, the matching groove 21 can also be arranged at other positions between the two groups of blocking mechanisms 20 .

In this embodiment, when the two-way door opening device of the present invention is used, the user can directly operate the toggle mechanism, that is, when the door body 82 of the refrigerator 800 needs to be opened to the right, the dial 41 can be directly rotated clockwise. , the dial 41 will drive the cam 421 to rotate clockwise, thereby pushing the connecting rod 2 to move to the right. Holding the second positioning shaft 422 to keep the position state of the cam 42 after the rotation, the blocking mechanism 20 on the left side of the connecting rod 2 gradually leaves the opening 10, and then breaks away from the restriction on the fixed column 813 on the side, thereby making the door of the refrigerator 800 The body 82 can be opened from this side.

During the above process, the blocking mechanism 20 on the right side of the connecting rod 2 further extends into the opening 10 to restrict the fixed column 813 on this side; in addition, under the torsion of the torsion spring 43 in the toggle mechanism, the present invention The two-way door opening device 100 can effectively maintain the state of the door opening body adjusted by the user.

When the door body 82 of the refrigerator 800 needs to be set to open to the left, it only needs to operate in reverse according to the above usage method. It can be seen from this that the two-way door opening device 100 in the present invention can directly adjust the door opening direction of the refrigerator 800 door body 82 by adjusting the toggle mechanism, which is simple and convenient, does not require professionals to operate the door body at all, saves time and effort, and The structure is simple and the cost is low.

In addition, as shown in FIG. 6 and FIG. 7, the elastic body 43 in another embodiment shown in FIG. 7 can also be a tension spring or a compression spring. 423 is arranged toward the front wall 113 , and the cam 42 and the first positioning shaft 116 are also located on the same straight line along the width direction of the housing 1 . In this embodiment, the rotation direction of the cam 42 is just opposite to that when the elastic body 43 is a torsion spring. Against each other, the tension spring or pressure spring in the stretched state pulls the second positioning shaft 422 of the cam 42 , so as to maintain the position state of the cam 42 after rotation.

In summary, the two-way door opening device 100 of the present invention directly extends the blocking mechanism 20 at both ends of the connecting rod 2, and pushes the connecting rod 2 to move left and right by twisting the dials 31 and 41, so that the blocking mechanism 20 at both ends of the connecting rod 2 Open or close the opening 10 on the casing 1, so that the user can directly operate the dials 31, 41 to realize the opening and closing switching of the blocking mechanism 20 on both sides of the connecting rod 2, and then the two-way door opening device 100 provided with the The refrigerator 800 switches the opening direction of the door body 82, which is simple and convenient, does not require professionals to operate the door body at all, saves time and effort, and has a simple structure and low cost.
