[0030] A drawer slide interlocking device includes: a drawer cabinet 1, with mounting grooves 2 on both sides of the inner wall of the drawer cabinet 1, and a drawer 3 slidably connected within the mounting grooves 2. The drawer 3 includes a drawer body 31, with an abutment 35 inside the drawer body 31. Below the abutment 35 is a groove 4, and a positioning buckle 5 is fixedly connected within the groove 4. A locking component is provided on the inner wall of the drawer cabinet 1 at a position corresponding to the groove 4. The locking component includes a fixing base 6, with a mounting groove 7 on the fixing base 6. A first slide groove 15 is formed at the bottom of the mounting groove 7, and the first slide groove 15 slides on the first slide groove 15. A movable seat 8 is connected to the mounting groove 7. A contact rod 9 is slidably connected to the side of the mounting groove 7 facing the groove 4. A connecting rod 10 is rotatably connected to the side of the mounting groove 7 away from the groove 4. A guide groove 11 is provided on the movable seat 8. A slider 12 is provided at the end of the connecting rod 10. The slider 12 is slidably connected to the guide groove 11. A first spring 13 is fixedly connected in the mounting groove 7. The other end of the first spring 13 is fixedly connected to the movable seat 8. Extension plates 14 are fixedly connected to both sides of the lower part of the first sliding groove 15. A linkage limiting member is provided below the movable seat 8. The linkage limiting member is rotatably connected to the extension plate 14.
[0031] When drawer 3 is closed, it is pushed inward and first touches the contact rod 9. The contact rod 9 pushes the moving seat 8 inward and slides it. At this time, the moving seat 8 drives the lower linkage limit piece to lock the positioning buckle 5, locking the drawer 3 so that it cannot be easily pulled open. When the drawer 3 is pulled open, it is first pushed inward slightly to unlock the locking component, and then the drawer 3 is pulled outward.
[0032] The guide groove 11 includes a first guide portion 111 and a second guide portion 113. A first misaligned groove 112 is provided on one side of the first guide portion 111, and a second misaligned groove 114 is provided on the other side of the first guide portion 111. The first guide portion 111, the first misaligned groove 112, the second guide portion 113 and the second misaligned groove 114 are connected end to end.
[0033] The sliding path of the slider 12 is guided by the first misalignment groove 112 and the second misalignment groove 114, so that when the drawer 3 is closed, the slider 12 moves along the second misalignment groove 114, the first guide part 111 and the first misalignment groove 112 to the concave point at the connection of the first misalignment groove 112 and the second guide part 113 in sequence, so that the linkage limiting member locks the positioning buckle 5 and prevents the drawer 3 from being easily pulled out; when the drawer 3 is opened, push it slightly inward first, so that the slider 12 slides along the second guide part 113 until the linkage limiting member leaves the positioning buckle 5, so that the drawer 3 can be pulled out smoothly.
[0034] The linkage limiting component includes an extension base 16 and a limiting hook 18. The extension base 16 is fixedly connected to the lower part of the movable seat 8. The extension base 16 is slidably connected to the first slide groove 15. A second slide groove 17 is provided on the extension base 16. The limiting hook 18 is rotatably connected to the extension plate 14. A sliding column 19 is fixedly connected to the limiting hook 18. The sliding column 19 is slidably connected to the second slide groove 17.
[0035] When the extended base 16 moves with the movable seat 8, the end of the second slide groove 17 contacts and drives the sliding column 19 to move until the limit hook 18 locks the positioning buckle 5.
[0036] An outer panel 32 is fixedly connected to the drawer body 31. A handle 33 is provided on the outer panel 32. Sliding parts 34 are fixedly connected to both sides of the drawer body 31. The sliding parts 34 are slidably connected to the mounting slide groove 2. Symmetrically distributed semi-circular grooves 21 are provided on the upper and lower sides of the sliding parts 34.
[0037] The semi-circular groove 21 is used in conjunction with the auxiliary positioning component 20 to help fix the drawer 3.
[0038] The inner walls of the drawer cabinet 1 are provided with auxiliary positioning components 20 on both sides. The auxiliary positioning component 20 includes a first fixing plate 201, a second spring 202 is fixedly connected to the first fixing plate 201, a second fixing plate 203 is fixedly connected to the other end of the second spring 202, and a semi-circular locking block 204 is fixedly connected to the second fixing plate 203.
[0039] To increase the stability of the connection between the first fixing plate 201 and the second fixing plate 203, a telescopic sleeve can also be provided between them; when the drawer 3 is stationary, the auxiliary positioning component 20 is engaged in the semi-circular groove 21 near the outer panel 32; during the process of pulling the drawer 3, the semi-circular locking block 204 disengages until it is pulled out and engaged in the semi-circular groove 21 away from the outer panel 32, thereby increasing the stability of the drawer 3 and the locking component.
[0040] The bottom of the semi-circular locking block 204 is provided with a first ball bearing 205, and the two sides of the second fixing plate 203 are provided with second ball bearings 206.
[0041] The first ball bearing 205 and the second ball bearing 206 increase the smoothness of the semi-circular locking block 204 entering and leaving the semi-circular groove 21, making the process of pulling out the drawer 3 smoother.
[0042] The working principle of the drawer slide rail interlocking device provided by this utility model is as follows:
[0043] When drawer 3 is closed, it is pushed inward and first touches the contact rod 9. The contact rod 9 pushes the moving seat 8 inward and slides it. At this time, the moving seat 8 drives the lower linkage limit piece to lock the positioning buckle 5, locking the drawer 3 so that it cannot be easily pulled open. When the drawer 3 is pulled open, it is first pushed inward slightly to unlock the locking component, and then the drawer 3 is pulled outward.
[0044] Compared with related technologies, the drawer slide rail interlocking device provided by this utility model has the following advantages:
[0045] By using the linkage limit component and positioning buckle 5, the drawer 3 can be locked after being closed, preventing it from being easily pulled open and increasing safety during use; the semi-circular groove 21 and the auxiliary positioning component 20 work together to assist in fixing the drawer 3, increasing the smoothness of pulling the drawer 3 open and the stability after it is opened.
[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
