Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a multi-linkage component and a linkage door. Background Technology

[0002] Currently, security doors typically consist of a door frame and a door handle. The locking process between the door handle and the door frame generally uses a lock and bolts. The door handle is first locked with the lock, then further locked with bolts on the top, bottom, or left and right sides. This multi-step locking process results in a poor user experience. Some existing security doors also utilize multi-linkage mechanisms. These mechanisms simultaneously open and close the door lock and bolts. Specifically, when the lock is opened or closed, the lock's drive connector transmits power to the bolts on the left and right sides, allowing the bolts to open or close along with the lock. However, existing multi-linkage doors only achieve linkage on the side of the lock, not on the top and bottom sides. Relying solely on left and right side locking makes the security of a security door less secure than simultaneous locking on all four sides, and the stability of this side-locking mechanism is also poor. Utility Model Content

[0024] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0025] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:

[0026] As shown in the figure, this utility model embodiment discloses a multi-linkage component, including a connector 4 connected to a door lock 3, a transmission component 6 fixedly connected to the connector 4, and a scissor assembly 5 connected to the transmission component 6. The connector 4 drives the transmission component 6 to drive the scissor assembly 5 to extend up and down. The connector 4 is connected to the scissor assembly 5 through the transmission component 6. The upper and lower sides of the scissor assembly 5 are connected to a longitudinal bolt 7 and a first transverse bolt 8 fixedly connected to the longitudinal bolt 7. The first transverse bolt 8 is provided with a limiting component and a telescopic component 83. The limiting component is fixedly connected to the longitudinal bolt 7 and is also connected to the telescopic component 83.

[0027] The multi-linkage component of this utility model is connected to the door lock 3 through the connector 4, and works with the transmission component 6 and the scissor assembly 5 to transmit the movement of the door lock 3 to the scissor assembly 5. Specifically, the movement of the door lock 3 will drive the connector 4 to rotate. Since the transmission component 6 is fixedly connected to the connector 4, the components of the transmission component 6 will rotate with the connector 4. The transmission component 6 converts the rotational movement into horizontal translation. The left and right ends of the scissor assembly 5 are fixed to the movable ends of the transmission component 6. The scissor assembly 5 will convert the horizontal movement into a vertical movement. The vertical movement of the scissor assembly 5 will push the longitudinal bolts 7 at the upper and lower ends of the scissor assembly 5 to both ends. The first transverse bolt 8, which is fixedly connected to the longitudinal bolt 7, will also move up and down with the longitudinal bolt 7.

[0028] In one embodiment of this application, the connecting member 4 is rotatably and fixedly connected to the transmission structure of the door lock 3. The transmission member 6 is provided with a screw 61 and two sleeves 62 threadedly fitted onto the screw 61. The screw 61 is fixedly connected to the connecting member 4, and the threads on both sides of the screw 61 are arranged in opposite directions. Further, the left and right ends of the scissor lift assembly 5 are respectively fixedly connected to the sleeves 62 fitted onto the screw 61. The two sleeves 62 move away from or closer to each other on the screw 61, causing the scissor lift assembly 5 to retract or extend.

[0029] In this embodiment, the transmission component 6 includes a screw 61 and two sleeves 62 that are threadedly fitted onto the screw 61. The sleeves 62 are rotatably fitted onto the screw 61, and the threads on both sides of the screw 61 are opposite. The screw 61 is fixedly connected to the connector 4. When the connector 4 rotates, it will drive the screw 61 to rotate. When the screw 61 rotates, the two sleeves 62 will move closer or further apart. Since the two ends of the scissor lift assembly 5 are respectively fixed to the two sleeves 62, the scissor lift assembly 5 will convert the horizontal operation of the sleeves 62 into a vertical operation.

[0030] In one embodiment of this application, the longitudinal bolt 7 is provided with a longitudinal connecting rod 71, one end of which is connected to the scissor lift assembly 5. In this embodiment, the scissor lift assembly 5 converts a horizontal movement into a vertical movement, and the vertical movement of the scissor lift assembly 5 pushes the longitudinal connecting rods 71 ​​at both ends of the scissor lift assembly 5 outwards.

[0031] In one embodiment of this application, the longitudinal bolt 7 is further provided with a movable rod 72 and a spring 73. The end of the longitudinal connecting rod 71 away from the scissor assembly 5 is provided with a straight slot. The movable rod 72 is sleeved on the end of the longitudinal connecting rod 71 away from the scissor assembly 5 and connected to the straight slot. The spring 73 is disposed between the movable rod 72 and the longitudinal connecting rod 71, and the spring 73 is also sleeved on the movable rod 72.

[0032] In this embodiment, when the vertical movement of the scissor lift assembly 5 pushes the longitudinal connecting rods 71 ​​at both ends of the scissor lift assembly 5 outwards, a straight slot is provided at the end of the longitudinal connecting rod 71. The end of the longitudinal connecting rod 71 is sleeved with the movable rod 72. One end of the movable rod 72 is limited by the straight slot, so that the movement of the movable rod 72 is restricted in the straight slot. A spring 73 is provided between the longitudinal connecting rod 71 and the movable rod 72. When the longitudinal connecting rod 71 is pushed upwards and downwards by the vertical movement of the scissor lift assembly 5, and when the movable rod 72 contacts the obstruction, the spring 73 is compressed. The spring 73 has a buffering effect and can prevent the movable rod 72 from being damaged due to excessive external force.

[0033] In one embodiment of this application, the limiting member is provided with a limiting block 81 and a fixing rod 82. One end of the fixing rod 82 is fixedly connected to the limiting block 81, and the other end of the fixing rod 82 is connected to the longitudinal connecting rod 71. The other end of the fixing rod 82 also passes through the longitudinal connecting rod 71 and connects to the telescopic member 83.

[0034] In this embodiment, since the first transverse bolt 8, which is fixedly connected to the longitudinal bolt 7, moves up and down with the longitudinal bolt 7, the lower side of the limiting member, in conjunction with the positioning post on the door body 1, can limit the maximum downward movement of the longitudinal connecting rod 71, that is, limit the maximum compression position of the scissor assembly 5. The end of the telescopic member 83 that contacts the door frame 2 is set to be spherical, and the spherical shape is set to have an arc greater in the width direction than in the length direction. In conjunction with the positioning groove of the door frame 2, when the spherical end of the telescopic member 83 does not fall into the positioning groove, the two sides of the door frame 2 in the width direction can be opened or closed along the arc of the spherical shape in the width direction. When the spherical end of the telescopic member 83 falls into the positioning groove, the spherical shape and the positioning groove are locked, so that the two sides of the positioning groove in the width direction cannot be opened or closed along the arc of the spherical shape in the width direction, and it is necessary to open or close from the two sides of the width direction that cannot be opened or closed along the arc of the spherical shape in the length direction.

[0035] In another embodiment of this application, a door body 1 and a door frame 2 are included. The door body 1 is provided with the multi-linkage component as described above. The door body 1 is also provided with a door lock 3. The multi-linkage component is connected to the door lock 3.

[0036] In one embodiment of this application, the door lock 3 is provided with a door handle 31 and a protective frame 32. The door handle 31 rotatably passes through the protective frame 32. A first bevel gear 33 is provided on the door handle 31. A connecting member 4 rotatably passes through the protective frame 32. The connecting member 4 is provided with a second bevel gear 34. The connecting member 4 is connected to the door handle 31 through the first bevel gear 33 and the second bevel gear 34. In this embodiment, when the door handle 31 is rotated, the first bevel gear 33 and the second bevel gear 34 cooperate to rotate the connecting member 4, so that the scissor lift assembly 5 can move up and down.

[0037] In one embodiment of this application, the door body 1 is further provided with a plurality of limiting rods 11, the limiting rods 11 being used to position the longitudinal connecting rods 71, the limiting rods 11 being provided with through holes, and the longitudinal connecting rods 71 ​​extending through the through holes to the upper and lower ends of the door body 1.

[0038] In one embodiment of this application, a limiting groove is provided on the side of the door body 1 to limit the vertical displacement of the telescopic member 83, and a positioning groove is also provided on the door frame 2 to lock the telescopic member 83.

[0039] In one embodiment of this application, a second transverse bolt is fixedly connected to the limiting rod 11. The second transverse bolt is provided with a sliding member and a sliding plate 13. The sliding member is provided with a fixed plate 12 fixedly connected to the limiting rod 11 and sliding wheels 14 rotatably connected to the four corners of the fixed plate 12. The sliding plate 13 is arranged horizontally between the sliding wheels 14.

[0040] In this embodiment, a second horizontal bolt is used to further fix the door body 1 horizontally. Specifically, a fixing plate 12 is provided on the limiting rod 11 and sliding wheels 14 are provided on the four corners of the fixing plate 12. The sliding plate 13 can slide on the sliding wheels 14, so that the sliding plate 13 slides in the horizontal direction of the fixing plate 12. With the door body 1 and the door frame 2 through the slot, the door body 1 can be further locked.

[0041] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
