Description

Technical Field

[0001] The utility model relates to the field of home decoration parts and components, in particular to a novel linkage mechanism for automatically closing and opening a door. Background Art

[0002] The linkage structure currently on the market has the following disadvantages:

[0003] 1. After the linkage mechanism is installed in the corresponding cabinet, the cabinet door will not be closed tightly and there will be a gap in the door panel.

[0004] 2. The linkage mechanism will affect the smoothness of the door panel and the operation of the door panel hinge, causing the door panel to be unable to close tightly.

[0005] 3. The current structure cannot automatically close and open the door

[0006] Therefore, a linkage structure is needed that can automatically close and open the door and can tightly close the door panel. Utility Model Content

[0007] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a linkage structure that can automatically close and open the door and can close the door panel.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0009] A novel linkage mechanism for automatic door closing and opening, characterized in that it comprises a push-out elastic member, a rotating shaft mounting seat, and a rotating connecting member;

[0010] One end of the push-to-pull elastic member is rotatably connected to the mounting cabinet at a first transfer point, and the other end is rotatably connected to the rotatable connecting member;

[0011] The rotating shaft mounting seat is arranged in the mounting cabinet and is provided with a second transfer point, and the rotating connecting member rotates around the second transfer point;

[0012] The rotating connecting member is transmission-connected to the door panel, and the rotating connecting member is directly or indirectly connected to the second transfer point; the rotating connecting member is rotationally connected to the pushing elastic member at a third transfer point, and the third transfer point is rotated by the rotating connecting member and moves on both sides of the line connecting the first transfer point and the second transfer point.

[0013] By adopting the above technical solution, the pushing force of the pushing elastic member on the rotating connecting member and the door panel plays different roles with the line connecting the first transfer point and the second transfer point as the dividing line. When the third transfer point is located on the side where the line connecting the first transfer point and the second transfer point is close to the door panel, the pushing force of the pushing elastic member on the rotating connecting member and the door panel is outward, which plays the role of opening the door. When the third transfer point is located on the side where the line connecting the first transfer point and the second transfer point is far away from the door panel, the pushing force of the pushing elastic member on the rotating connecting member and the door panel is inward, which plays the role of closing the door and tightening the gap between the door panel and the installation cabinet. In this way, in the process of opening and closing the door, the automatic door opening and automatic door closing can be selected by driving the third transfer point to move to which side of the line connecting the first transfer point and the second transfer point, and the door panel can be effectively closed without leaving any gaps.

[0014] As an improved solution, the push-to-pull elastic member is connected to the installation cabinet through a first base, and the first base is provided with a plurality of rotating connection grooves matching the push-to-pull elastic member. The push-to-pull elastic member selects one of the rotating connection grooves to connect to form a first transfer point.

[0015] By adopting the above technical solution, the specific position of the first transfer point can be changed by changing which rotating connecting groove of the first base the push-to-pull elastic member is connected to, thereby achieving adjustment of the key dividing line of the connection between the first transfer point and the second transfer point, which can adapt to more actual on-site needs.

[0016] As an improved solution, a limiting slide rail is further provided in the installation cabinet, and the first base is movably disposed on the limiting slide rail.

[0017] Specifically, the first base is movably and lockably arranged on the limiting slide rail, and a blocking member can be arranged on the limiting slide rail to lock the position of the first base. It can also be achieved in the form of a threaded rod and a threaded hole arranged on the first base.

[0018] By adopting the above technical solution, the specific position of the first transfer point can be changed by adjusting the position of the first base on the limiting slide rail, thereby adjusting the key dividing line of the connection between the first transfer point and the second transfer point, which can adapt to more actual on-site needs.

[0019] As an improved solution, it also includes a linkage cross bar, one end of which is rotatably connected to the second transfer point; a second base is arranged on the door panel, a slide groove is arranged on the second base, and a sliding pin is arranged at the other end of the linkage cross bar, and the sliding pin is slidably arranged in the slide groove.

[0020] By adopting the above technical solution, the sliding pin of the linkage cross bar can slide freely in the sliding groove of the second base, so that the door panel is actually flexibly driven by the linkage cross bar instead of being rigidly fixed. When closing the door, the door panel can be adaptively installed in the cabinet body to reduce the gap.

[0021] As an improved solution, a roller / ball is sandwiched between the sliding pin and the sliding groove.

[0022] By adopting the above technical solution, the friction and wear between the sliding pin and the sliding groove can be reduced, the use is smoother, and the service life is extended and the durability is enhanced.

[0023] As an improved solution, an elastic contraction member / magnetic attraction member is provided between the linkage cross bar and the door panel.

[0024] By adopting the above technical solution, the door panel can be prevented from being too far away from the linkage cross bar while ensuring the flexibility between the linkage cross bar and the door panel.

[0025] As an improved solution, the extending elastic member is a gas spring, and two ends of the gas spring are detachably connected to the first transfer point and the third transfer point respectively.

[0026] By adopting the above technical solution, gas springs (also called gas struts or hydraulic rods, etc.) with different stroke lengths and different thrust sizes can be flexibly replaced according to actual needs to meet actual needs on site.

[0027] As an improved solution, a flexible buffer pad is provided on the side of the push elastic member facing the inner wall of the installation cabinet.

[0028] By adopting the above technical solution, when the push-pull elastic member pushes the door panel to close, before the door panel hits the installation cabinet, the push-pull elastic member first contacts the flexible buffer member, thereby slowing down the door panel and reducing the collision sound when closing the door.

[0029] Compared with the prior art, the beneficial effects of the utility model are:

[0030] The pushing force of the pushing elastic member on the rotating connecting member and the door panel plays different roles with the line connecting the first transfer point and the second transfer point as the dividing line. When the third transfer point is located on the side where the line connecting the first transfer point and the second transfer point is close to the door panel, the pushing force of the pushing elastic member on the rotating connecting member and the door panel is outward, which plays the role of opening the door. When the third transfer point is located on the side where the line connecting the first transfer point and the second transfer point is far away from the door panel, the pushing force of the pushing elastic member on the rotating connecting member and the door panel is inward, which plays the role of closing the door and tightening the gap between the door panel and the installation cabinet. In this way, in the process of opening and closing the door, automatic door opening and automatic door closing can be selected by driving the third transfer point to move to which side of the line connecting the first transfer point and the second transfer point, and the door panel can be effectively closed without leaving any gaps.

[0047] Implementation case 1:

[0048] As attached Figure 1-2 As shown, a novel linkage mechanism for automatic door closing and opening is characterized in that it includes a push-out elastic member 1, a rotating shaft mounting seat 2, and a rotating connecting member 3;

[0049] One end of the push elastic member 1 is rotatably connected to the mounting cabinet 7 at the first transfer point 4, and the other end is rotatably connected to the rotatable connecting member 3;

[0050] The rotating shaft mounting seat 2 is arranged in the mounting cabinet 7 and is provided with a second transfer point 5, and the rotating connecting member 3 rotates around the second transfer point 5;

[0051] The rotating connecting member 3 is transmission connected to the door panel 8, and the rotating connecting member 3 is directly or indirectly connected to the second transfer point 5; the rotating connecting member 3 is rotationally connected to the pushing elastic member 1 at the third transfer point 6, and the third transfer point 6 is rotated by the rotating connecting member 3 and moves on both sides of the line connecting the first transfer point 4 and the second transfer point 5.

[0052] The pushing force of the pushing elastic member 1 on the rotating connecting member 3 and the door panel 8 plays different roles with the line connecting the first transfer point 4 and the second transfer point 5 as the dividing line. When the third transfer point 6 is located on the side where the line connecting the first transfer point 4 and the second transfer point 5 is close to the door panel 8, the pushing force of the pushing elastic member 1 on the rotating connecting member 3 and the door panel 8 is outward, which plays the role of opening the door. When the third transfer point 6 is located on the side where the line connecting the first transfer point 4 and the second transfer point 5 is far away from the door panel 8, the pushing force of the pushing elastic member 1 on the rotating connecting member 3 and the door panel 8 is inward, which plays the role of closing the door and tightening the gap between the door panel 8 and the installation cabinet 7. In this way, in the process of opening and closing the door, the automatic door opening and automatic door closing can be selected by driving the third transfer point 6 to move to which side of the line connecting the first transfer point 4 and the second transfer point 5, and the door panel 8 can be effectively closed without leaving a gap.

[0053] The push-to-pull elastic member 1 is connected to the mounting cabinet 7 via a first base 9 , and the first base 9 is provided with a plurality of rotation connection grooves matching the push-to-pull elastic member 1 , and the push-to-pull elastic member 1 selects one of the rotation connection grooves to connect to form a first transfer point 4 .

[0054] The specific position of the first transfer point 4 can be changed by changing which rotating connection groove of the first base 9 the push-to-pull elastic member 1 is connected to, thereby adjusting the key dividing line of the connection between the first transfer point 4 and the second transfer point 5, which can adapt to more actual on-site needs.

[0055] A limiting slide rail is also provided in the installation cabinet 7, and the first base 9 is movably arranged on the limiting slide rail.

[0056] Specifically, the first base 9 is movably and lockably arranged on the limiting slide rail. A blocking member can be arranged on the limiting slide rail to lock the position of the first base 9. It can also be achieved in the form of a threaded rod and a threaded hole arranged on the first base 9.

[0057] By adjusting the position of the first base 9 on the limiting slide rail, the specific position of the first transfer point 4 can be changed, thereby adjusting the key dividing line of the connection line between the first transfer point 4 and the second transfer point 5, which can adapt to more actual on-site needs.

[0058] It also includes a linkage cross bar 11, one end of which is rotatably connected to the second transfer point 5; a second base 12 is provided on the door panel 8, a slide groove 13 is provided on the second base 12, and a sliding pin is provided at the other end of the linkage cross bar 11, and the sliding pin is slidably provided in the slide groove 13.

When closing the door, the door panel 8 can be adaptively installed in the cabinet body 7 to reduce the gap.

[0060] A roller / ball is sandwiched between the sliding pin and the sliding groove 13 .

[0062] An elastic contraction member / magnetic attraction member is provided between the linkage cross bar 11 and the door panel 8 .

[0063] It is possible to ensure the flexibility between the linkage cross bar 11 and the door panel 8 while preventing the door panel 8 from being too far away from the linkage cross bar 11 .

[0064] The pushing elastic member 1 is a gas spring, and two ends of the gas spring are detachably connected to the first transfer point 4 and the third transfer point 6 respectively.

[0065] Gas springs (also called gas struts or hydraulic rods, etc.) with different stroke lengths and thrust sizes can be flexibly replaced according to actual needs to meet actual needs on site.

[0066] A flexible buffer pad is provided on one side of the push elastic member 1 facing the inner wall of the installation cabinet 7 .

[0067] When the push-pull elastic member 1 pushes the door panel 8 to close, before the door panel 8 hits the installation cabinet 7, the push-pull elastic member 1 first contacts the flexible buffer member, thereby slowing down the door panel 8 and reducing the collision sound when closing the door.

[0068] In summary, after reading the utility model document, ordinary technicians in this field can make various other corresponding transformation schemes based on the technical scheme and technical concept of the utility model without creative mental labor, and different application scenarios all fall within the scope of protection of the utility model.
