For the side-by-side combination refrigerator, a double-shaft hinge is needed to meet the installation requirement, the door body has no fixed rotation center in the opening and closing process due to the characteristic of the double-shaft hinge, and the door body has radial movement, so that the door closer in two forms is difficult to be applied.

The utility model provides a door closer which is simple in structure and wide in application range, and can conveniently and fast realize the tight closing between a first main body and a second main body.

Referring to fig. 4 to 6, in the present embodiment, the door closer 1 includes a fixing device 20 provided on a first body and a connecting device 10 provided on a second body; an avoidance groove is formed on the fixing device 20, and the space between the two opposite side walls of the avoidance groove can be elastically adjusted; the connecting device 10 comprises a connecting piece 100, and a limiting protrusion 200 is arranged on the side surface of the connecting piece 100 opposite to the inner side wall of the avoidance groove; when the limiting protrusion 200 penetrates into the avoidance groove, the distance between the two opposite side walls of the avoidance groove is increased; when the limiting protrusion 200 passes through the avoidance groove, the first body and the second body are mutually closed.

The fixing device 20 with the avoidance groove is arranged on the first main body, the distance between the two opposite side walls of the avoidance groove is set to be elastically adjustable, the connecting piece 100 is arranged on the second main body, and the limiting protrusion 200 is arranged on the side surface of the connecting piece 100 opposite to the side wall of the avoidance groove; in the closing process of the first body and the second body, the limiting protrusion 200 penetrates into the avoidance groove, the limiting protrusion 200 or the connecting piece 100 pushes against the side wall of the avoidance groove, and the distance between the two opposite side walls of the avoidance groove is increased; after the spacing arch 200 passes dodge the groove, dodge elastic return to initial position or support and press between the opposite both sides wall in groove connecting piece 100, spacing arch 200 dodge unable the opposite direction removal towards penetrating under the blocking of groove lateral wall, just this moment first main part and second main part just are closed each other, the second main part is unable to be kept away from the direction of first main part removes, realizes the inseparable closure between first main part and the second main part.

Specifically, in one embodiment, the fixing device includes two spaced stoppers 400, one of the stoppers 400 is elastically movable in a direction away from the other stopper 400, and the two stoppers 400 form the avoidance groove; the limiting protrusions 200 are disposed on two sides of one end of the connecting piece 100, which is close to the stop piece 400, and when the connecting piece 100 penetrates between the two stop pieces 400, the limiting protrusions 200 push against the stop pieces 400.

In the process of closing the first body and the second body, the connecting piece 100 and the stop piece 400 relatively move, and the connecting piece 100 passes through between the two stop pieces 400; limiting protrusions 200 are disposed on two sides of the connecting piece 100, which are close to one end of the stop piece 400, and the limiting protrusions 200 can push the stop piece 400 in the process of passing through the space between the two stop pieces 400 of the connecting piece 100. One of the stoppers 400 is elastically movable in a direction away from the other stopper 400, and the distance between the two stoppers 400 is increased under the pushing of the limit projection 200; after the whole spacing protrusion 200 passes through the space between the two stop members 400, the spacing protrusion 200 releases the pushing action on the stop members 400, the stop members 400 elastically return to the initial position or press against the connecting member 100, and the spacing protrusion 200 cannot move out of the space between the two stop members 400 in opposite directions without external force, i.e. the spacing protrusion 200 is limited on one side of the stop member 400 away from the second body, and the second body cannot move or rotate in a direction away from the first body. By setting the length of the limiting protrusion 200 extending towards the first body, when the limiting protrusion 200 completely passes through between the two stop pieces 400, the first body and the second body are just mutually closed, and under the action of no external force, the limiting protrusion 200 cannot move again, so that the first body and the second body are tightly closed.

By arranging two elastically movable stoppers 400 on the first body at intervals, one of the stoppers 400 can elastically move in a direction away from the other stopper 400, and arranging a connecting member 100 and limiting protrusions 200 on both sides of one end of the connecting member 100 near the stopper 400 on the second body; in the closing process of the first body and the second body, the connecting piece 100 penetrates between the two stopping pieces 400, the limiting protrusion 200 pushes against the stopping pieces 400, and the interval between the two stopping pieces 400 is increased; after the limiting protrusion 200 passes through the space between the two stop members 400, the stop members 400 elastically return to the initial position or press against the connecting member 100, the limiting protrusion 200 cannot move in the opposite penetrating direction under the blocking of the stop members 400, and at this time, the first body and the second body are just mutually closed, and the second body cannot move in the direction away from the first body, so that the tight closing between the first body and the second body is realized. The fixing device 20 and the connecting device 10 are arranged separately, so that the connection relation between the first main body and the second main body is not limited, the application range is wide, the structure is simple, and the installation is convenient.

Referring to fig. 2 and 3, in an embodiment, the fixing device 20 further includes a base 500, the base 500 is mounted on the first body, and the two stoppers 400 are elastically movably disposed on the base 500.

By arranging the stop 400 on the base 500, the fixing device 20 is conveniently installed on the first body through the base 500, and the base 500 can be conveniently and rapidly installed on the first body through a mode of bolt connection, screw connection, magnetic connection or adhesive connection.

Specifically, the fixing device 20 further includes two sliding blocks 600, the base 500 includes a bottom plate 510 and two side plates 520 disposed on the bottom plate 510, the two sliding blocks 600 are disposed between the two side plates 520 and are disposed at the same direction and interval with the two side plates 520, the two sliding blocks 600 are connected to the two side plates 520 through elastic members 700 in a one-to-one correspondence, the two stopping members 400 are connected to the two sliding blocks 600 in a one-to-one correspondence, and the stopping members 400 are disposed on one side of the sliding blocks 600 facing the other sliding block 600.

When the connecting member 100 does not penetrate between the two stopping members 400, the elastic member 700 is in an initial state not affected by an external force; when the connecting piece 100 passes through the space between the two stop pieces 400, the stop piece 400 is pushed by the limiting protrusion 200, the stop piece 400 drives the sliding block 600 to move towards the direction of the side plate 520 connected with the sliding block 600, and the elastic piece 700 generates compression deformation. After the limit protrusion 200 passes through the space between the two stop members 400, the limit protrusion 200 releases the pushing effect on the stop members 400, the elastic member 700 has a position that returns to the initial state under the action of elastic force, and pushes the sliding block 600, and the sliding block 600 drives the stop members 400 to move in a direction away from the side plate 520 connected with the sliding block 600. If the distance between the two stoppers 400 is greater than the width of the connecting piece 100 when the elastic piece 700 is in the initial state, the elastic piece 700 finally returns to the initial state; if the distance between the two stoppers 400 is smaller than the width of the connecting piece 100 when the elastic piece 700 is in the initial state, the elastic piece 700 finally returns to the position where the stoppers 400 press the connecting piece 100. Specifically, the elastic member 700 includes, but is not limited to, a spring, etc.

Preferably, the slider 600 or the bottom plate 510 may be made of a material having a low friction coefficient to reduce friction resistance when the slider 600 moves and wear when the slider 600 moves.

Further, in order to limit the moving path of the sliding blocks 600, in one embodiment, a sliding groove 540 extending along the direction in which the two stoppers 400 are spaced apart is provided on the bottom plate 510, and the two sliding blocks 600 are disposed in the sliding groove 540.

Considering that the sliding block 600 easily shakes at the upper end of the sliding block 600 during sliding along the sliding groove 540, so that the sliding block 600 is separated from the sliding groove 540, in this embodiment, the base 500 further includes a top plate 530 disposed opposite to the bottom plate 510, the side plate 520 connects the bottom plate 510 and the top plate 530, at least one of opposite end surfaces of the bottom plate 510 and the top plate 530 is provided with a sliding groove 540 extending along a direction in which two stoppers 400 are disposed at intervals, and two sliding blocks 600 are disposed in the sliding groove 540. By providing the bottom plate 510 and the top plate 530, when the slider 600 is located in the sliding groove 540, the upper end and the lower end of the slider 600 are both limited, so as to ensure that the slider 600 slides stably in the sliding groove 540.

Referring to fig. 3, in an embodiment, the stopper 400 is rotatably connected to the slider 600, and the stopper 400 can be circumferentially rotated along the moving direction of the connecting member 100.

By rotationally connecting the stop piece 400 to the slider 600, when the stop piece 400 is pushed by the stop projection 200, sliding friction between the stop piece 400 and the stop projection 200 is converted into rolling friction, so that friction resistance and friction loss between the stop piece 400 and the stop projection 200 are reduced in the process that the stop projection 200 pushes the stop piece 400.

Referring to fig. 4 to 6, considering that when the connector 100 penetrates between two stoppers 400, if the stopper protrusion 200 vertically abuts against the stoppers 400, the stopper 400 has too high resistance to penetration of the connector 100, the stopper 400 is not convenient to move away from the other stopper 400 under the abutment of the stopper protrusion 200, thereby improving the closing difficulty of the first door 40 and the second door 40. Therefore, in an embodiment, the limiting protrusion 200 includes a first limiting portion, a first guiding inclined plane 210 is disposed on a side of the first limiting portion facing away from the connector 100, along a direction from the first body toward the second body, a distance between the first guiding inclined plane 210 and the connector 100 is gradually increased, and when the limiting protrusion 200 pushes against the stopper 400, the stopper 400 pushes against the first guiding inclined plane 210.

In the process of pushing the stopper 400, the stopper 400 moves along the first guiding inclined plane 210, and the stopper 400 receives a component force moving away from the other stopper 400, so that the distance between the two stoppers 400 is increased, and the stopper 200 is convenient to pass between the two stoppers 400. Along the direction from the first body toward the second body, the distance from the first guiding inclined surface 210 to the connecting piece 100 gradually increases, and as the portion of the first limiting portion passing between the two stopping pieces 400 increases, the distance between the two stopping pieces 400 also gradually increases, so that the limiting protrusion 200 finally passes between the two stopping pieces 400 as a whole.

Further, the limiting protrusion 200 further includes a second limiting portion connected to the first limiting portion and close to one end of the second main body, a second guiding inclined plane 220 is disposed on a side of the second limiting portion, facing away from the connecting piece 100, and along the direction of the first main body toward the second main body, the distance between the second guiding inclined plane 220 and the connecting piece 100 is gradually reduced.

Since the distance between the second guiding inclined surface 220 and the connecting piece 100 is gradually reduced along the direction of the first body toward the second body, after the first limiting portion passes between the two stopping pieces 400, the stopping pieces 400 have a tendency to elastically return to the initial position, that is, the stopping pieces 400 move toward the other stopping piece 400, the stopping pieces 400 push against the second guiding inclined surface 220, so that the connecting piece 100 is promoted to continuously move toward the direction penetrating between the two stopping pieces 400, that is, the mutual closing between the first body and the second body is promoted.

With continued reference to fig. 4 to 6, in an embodiment, a limit groove 300 is formed at a connection portion between the second guiding inclined surface 220 and a side surface of the connecting piece 100, and a bottom surface of the limit groove 300 is adapted to an outer circumferential surface of the stop piece 400.

After the whole spacing protrusion 200 passes through between two spacing pieces 400, the spacing pieces 400 are abutted in the spacing grooves 300, and by setting the bottom surface of the spacing grooves 300 to be matched with the outer peripheral surface of the spacing pieces 400, the stability of the state that the spacing pieces 400 are abutted in the spacing grooves 300 can be improved, namely, the spacing of the spacing protrusions 200 separated from the two spacing pieces 400 is avoided, so that the first main body and the second main body keep a tightly closed state.

The utility model also provides the refrigerator 2.
