Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1 to 7, the liftable drawer includes:
the drawer body 1 is used for containing articles, can be of a box body structure or a frame structure, and can be any one of the prior art according to requirements;
a drawer panel 2; the drawer is positioned on the front end surface of the drawer and can be provided with components such as a handle and the like. Two fifth connecting rods 35 are arranged on the inner surface of the drawer panel in parallel; the fifth link 35 serves as a connection member for connecting the second link 321 and the fourth link 341 to the drawer panel. The front end surface of the fifth link 35 is further provided with a second stopper 42 as a limiting member when the drawer body is lifted.
The lifting mechanism is used for supporting and installing the drawer body 1, is connected to the drawer panel 2, and comprises a first supporting piece 31, a second supporting piece 32, a third supporting piece 33 and a fourth supporting piece 34.
The first support 31 includes two first links 311 arranged in parallel and at least one first connecting rod 312 connected between the two first links; in this embodiment, two first connecting rods 312 are provided, and are respectively connected to two end portions of the first connecting rod 311; the first supporting member is in a rectangular frame structure. The first support member may also be of a plate-like configuration.
The drawer body 1 is supported and arranged on the first support 32.
The fourth supporting member 34 includes two parallel fourth connecting rods 341, and in order to make the whole upgrading mechanism structure more stable, the tail ends of the two fourth connecting rods 341 are connected with a fourth connecting rod 342; the head parts of the two fourth connecting rods are hinged with the drawer panel 2.
The head end of the first connecting rod 311 is connected with two clamping plates 313 which are arranged in parallel, a gap 314 is arranged between the lower parts of the clamping plates and the first connecting rod 311, and a first stop block 41 for limiting the lifting of the drawer body is formed at the lower part of the front end surface of the exposed first connecting rod 311.
The second support 32 includes two second links 321 arranged in parallel; the head part of the clamp is of a circular structure matched with the two clamping plates 313, and the clamp is clamped between the two clamping plates 313 and is hinged with the two clamping plates 313; when the drawer body is lifted, the straight rod portion of the second link abuts against the first stopper 41, and the drawer body is prevented from shaking.
The tail of the second link has a convex projection 322, and the connecting shaft 323 passes through the projection 322 and the fifth link 35, so that the second link is rotatably connected to the fifth link 35. The protrusion 322 is disposed corresponding to the second stopper 42, so that the straight rod portion of the second link abuts against the second stopper 42 in the lifted state of the drawer body.
When the second connecting rod abuts against the first stop block 41 and the second stop block 42 in the lifting state of the drawer, an included angle between the first connecting rod and the fifth connecting rod or the drawer panel is 91-95 degrees, and the included angle is 92 degrees in the embodiment; the whole lifting mechanism is in a slightly outward-inclined state, so that the lifting mechanism stably supports the drawer body, and the lifting mechanism formed by the connecting rods hinged with each other is prevented from falling back or rotating towards other directions.
The third support 33 includes two third links 331 arranged in parallel; one end of the third connecting rod 331 is hinged to the tail of the corresponding first connecting rod, a third connecting rod 332 is connected between the other ends of the two third connecting rods 331, and the two ends of the third connecting rod 332 are rotatably connected to the middle positions of the two fourth connecting rods 342.
In this embodiment, L1 ═ L4, L2 ═ L3 ═ L5; and L3 ═ L6.
L1 is the length of the first link 311; l2 is the length of the second link; l3 is the length of the third link; l4 is the length of the fourth link; l5 is the length of the fifth link; l6 is the length from the hinge point of the third link and the fourth link to the tail of the fourth link. Namely:
the first link 311 and the fourth link 341 are equal in length; the second link 321, the third link 331 and the fifth link are equal in length. Under the drawer body state of falling back, third connecting rod and fourth connecting rod coincidence to the length of third connecting rod equals with the distance of pin joint to fourth railing afterbody.
The first stopper 41 and the second stopper 42 constitute positioning members in this embodiment.
The disinfection cabinet using the liftable drawer has the advantages that the two fourth connecting rods are used as sliding rails and are limited on the guide rails 51 of the disinfection cabinet body 5 in a sliding mode, and the drawer body is a hollow drawer basket for the disinfection cabinet. In the embodiment, two drawers are arranged in parallel up and down in the cabinet body.
After the drawer is pulled open, the drawer panel is pressed outwards and rotates relative to the fourth connecting rod, and when the lower part of the drawer panel is abutted against the fourth connecting rod, the drawer panel is opened to a limit position and is positioned on the same plane with the fourth connecting rod; at the moment, the pull basket is pulled upwards slightly, the pull basket drives the first connecting rod to move upwards, and the first connecting rod drives the first connecting rod and the third connecting rod to rotate; as shown in fig. 3; when the two end parts of the second connecting rod are rotated to abut against the first stop block and the second stop block respectively, the included angle between the second connecting rod and the fifth connecting rod is 92 degrees, the lifting mechanism forms a parallelogram with small inclination, and the drawer body slightly tilts forwards, so that the drawer body can not move when no external force exists, and the drawer body is in a stable lifting state.
When the drawer is pushed back, the drawer body is slightly pushed backwards, the drawer body drives the second connecting rod and the third connecting rod to rotate reversely through the first connecting rod, the drawer body slowly falls back until the second connecting rod is overlapped with the fifth connecting rod, the first connecting rod and the third connecting rod are on the same straight line and are overlapped with the fourth connecting rod, and the drawer completely falls back; as shown in fig. 5 and 6, the drawer can be smoothly closed.
