[0033] Example

[0034] like Figs. 1-2 As shown, the utility model provides a non-powered connecting rod double-door mechanism, which includes: a double-door assembly 1, a connecting rod assembly 2 and a push rod 3.

[0035] The double door assembly 1 includes a door frame 101 and a door panel 102 rotatably connected to the door frame 101 via a rotating shaft 103. The door panel 102 is arranged on the travel route of the accumulation chain trolley group. The two ends of the connecting rod assembly 2 are respectively connected to the two rotating shafts 103 for synchronously rotating the rotating shafts 103 so that when one door is pushed open, the other door is also opened synchronously; one end of the push rod 3 is connected to the door panel 102, and the other end faces the travel direction of the accumulation chain trolley group. The height of the push rod 3 is consistent with the height of the secondary hanging beam below the accumulation chain trolley group, and the push rod 3 is used to contact the secondary hanging beam below the accumulation chain trolley group.

[0036] Since the double door assembly 1 is arranged on the travel path of the accumulation chain trolley group, the push rod 3 provided on the door body is located in the travel direction facing the accumulation chain trolley group, and the installation height of the accumulation chain push rod 3 is consistent with the height of the secondary lifting beam of the accumulation chain trolley group. When the accumulation chain trolley group moves forward, the secondary lifting beam contacts the push rod 3 of the door panel 102, and the traction force of the chain is used to push the door panel 102 open. Moreover, the bottoms of the two door panels 102 are connected together by the connecting rod assembly 2, so that the opening and closing of the two door panels 102 are kept synchronous.

[0037] After the door panel 102 is pushed open, in order to ensure that the door panel 102 can quickly return to closing, specifically, it also includes a reset member installed on the rotating shaft 103, and the reset member abuts between the door frame 101 and the door panel 102, and is used to rebound and close the door panel 102. The reset member can adopt a reset spring, and use the spring force to reset the door panel 102, so that the two door panels 102 are closed.

[0038] The end of the push rod 3 away from the door panel 102 is tilted toward the door gap close to the double door assembly 1, and the far end of the push rod 3 is moved closer to the door gap in the middle of the double door assembly 1, so that the secondary suspension beam passing through the middle can better contact the far end of the push rod 3.

[0039] In order to strengthen the connection strength between the push rod 3 and the door plate 102, a support rod 4 is further arranged between the push rod 3 and the door plate 102 to form a triangular support structure, so that the end of the push rod 3 in contact with the door plate 102 cooperates with the support rod 4 to form a triangular support structure, and the connection is more firm and stable, and the inclined push rod 3 is more reasonable in force and less likely to be damaged when being pushed.

[0040] In order to avoid injury caused by the protruding part of the push rod 3, the end of the push rod 3 away from the door plate 102 is provided with an arc-shaped part 5 curved towards the door plate 102, which will not hurt the secondary hanging beam or the workpiece below when the arc-shaped part 5 contacts the secondary hanging beam.

[0041] The inside of the arc-shaped part 5 is filled with a support plate 6 to strengthen the structural strength of the arc-shaped part 5.

[0042] In the embodiment, the link assembly 2 comprises a first link 201, a rotating support plate 203 and a second link 202 connected in sequence, the rotating support plate 203 is arranged to rotate at the center thereof, the center of the rotating support plate 203 is positioned by connecting a rotating shaft, and the rotating shaft is fixed to realize positioning rotation, the rotating support plate 203 can rotate around the center thereof, the center position remains fixed, and the ends of the first link 201 and the second link 202 away from the rotating support plate 203 are respectively provided with a rotating arm 204, and the rotating arm 204 is further connected and fixed with the rotating shaft 103. The rotating support plate 203 is arranged to rotate around the center thereof due to the center fixed, and when the door plate 102 on the left side mounting the push rod 3 rotates to drive the first link 201 to move, the rotating support plate 203 can drive the first link 201 and the second link 202 at both ends to relatively move, and then drive the second link 202 at the other end to move, and then drive the door plate 102 on the right side to rotate.

[0043] The rotating arm 204 is connected with the rotating shaft 103 at the hinge of the door plate 102, and when the second link 202 and the first link 201 at both ends are displaced, the rotating arm 204 is driven to rotate around the rotating shaft 103, and then drives the two door plates 102 to rotate synchronously to open or close.

[0044] Specifically, to achieve the adjustment of the rotation angle of the door panel 102, the first connecting rod 201 and the second connecting rod 202 are both telescopic connecting rods, which include a double-end screw rod 2011 and a connecting end rod 2012 screwed on both ends of the double-end screw rod 2011; by rotating the double-end screw rod 2011, the distance between the distal ends of the connecting end rods 2012 on both ends is changed, thereby changing the length of the overall connecting rod, so that the first connecting rod 201 or the second connecting rod 202 can change the range of displacement, thereby changing the rotation angle of the two rotating arms 204, and then changing the opening angle of the double-leaf door; at the same time, the first connecting rod 201 and the second connecting rod 202 are both telescopic connecting rods, and the sealing degree of the door panel 102 when closing can be adjusted by changing a single connecting rod; if the closing angle of one of the door panels 102 is not in place, the rotation angle of the door panel 102 can be changed by adjusting the length of the connecting rod connected to the door panel 102, so as to achieve better closing effect or opening effect.

[0045] Finally, it should be pointed out that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
