The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized object and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
Refer to shown in Fig. 1, the drawer anti-falling mechanism of present embodiment, comprises drawer 1 and drawer installation main body 2.
Described drawer 1 comprises drawer panel 10, drawer backboard 11, drawer side and drawer-bottom board 12, described drawer-bottom board 12 levels are embedded in the mounting groove of offering on drawer panel 10, drawer backboard 11 and drawer side, make the bottom of drawer-bottom board 12 higher than the bottom of drawer backboard 11.Certainly, other bottoms that can realize drawer-bottom board 12 also can adopt higher than the syndeton of the bottom of drawer backboard 11, as long as make height of formation poor (card rank) between the bottom of drawer-bottom board 12 and the bottom of drawer backboard 11, the fore-end that is positioned at jointed shaft when position-stopping plate 3 like this perk and after leaning on drawer-bottom board 12 under self gravitation effect, drawer backboard 11 advances to the position of position-stopping plate 3 and will be blocked by position-stopping plate 3, make drawer 1 cannot depart from drawer main body 2 is installed, prevent that drawer 1 from dropping.
Described drawer is installed the installation main body of main body 2 as drawer 1, can be the finished product furniture such as desk, cupboard, can be also parts independently, refills on finished product furniture such as being fitted on desk, cupboard when to be used.Drawer is installed main body 2 and is provided with drawer mounting groove 20 and position-stopping plate 3, described drawer 1 can be arranged in described drawer mounting groove 20 slidingly back and forth, concrete, this slip set-up mode can be: on the sidewall of the outside of drawer side and drawer mounting groove 20, correspondence is provided with railroad, certainly, do not get rid of other known implementations.Described position-stopping plate 3 is positioned at described drawer mounting groove 20 and is positioned at the below of drawer-bottom board 12, described position-stopping plate 3 is articulated and connected and installs in main body 2 and can rotate around jointed shaft 30 front and back at drawer, the fore-end that position-stopping plate 3 is positioned at jointed shaft 30 overweights position-stopping plate 3 and is positioned at the rear end part of jointed shaft 30, and the rear end part that position-stopping plate 3 is positioned at jointed shaft 30 leans on drawer-bottom board 12 after drawer 1 packs drawer mounting groove 20 into.
Operation principle of the present utility model is as follows: when drawer 1 does not pack drawer mounting groove 20 into when interior, position-stopping plate 3 is under self gravitation effect, and its rear end part that is positioned at jointed shaft 30 is upturned; When drawer 1 packs drawer mounting groove 20 into, as shown in Figure 3, drawer backboard 11 promotes position-stopping plate 3 and rotates backward, and makes position-stopping plate 3 substantially become level and can not hinder drawer 1 and continue to pack into; When drawer 1 packs into after drawer mounting groove 20, as shown in Figure 4, between the bottom of the bottom of drawer backboard 11 and drawer-bottom board 12, form a difference in height (accommodation space), position-stopping plate 3 is rotated forward under self gravitation effect, its rear end part that is positioned at jointed shaft 30 is upturned naturally until the front end of position-stopping plate 3 arrives to the rear end of baffle plate 6 or position-stopping plate 3 leans on drawer-bottom board 12, pulling the drawer out 1 o'clock like this, drawer backboard 11 advances to the position of position-stopping plate 3 and will be blocked by position-stopping plate 3, make drawer 1 cannot depart from drawer main body 2 is installed, prevent that drawer 1 from dropping.
In the above-described embodiments, more rapidly reliable for the action that makes position-stopping plate 3, the weight that position-stopping plate 3 is positioned at the fore-end of jointed shaft 30 is more than the twice of position-stopping plate 3 weight that is positioned at the rear end part of jointed shaft 30.Be enough to like this overcome the frictional force between position-stopping plate 3 and jointed shaft 30, effectively prevent that position-stopping plate 3 is because of the phenomenon that clamping stagnation cannot rotate, guarantee that the rear end part that position-stopping plate 3 is positioned at jointed shaft 30 is upturned under Action of Gravity Field, improves the reliable and stable of product.
In the above-described embodiments, shown in Fig. 2, the below that is positioned at drawer-bottom board 12 in described drawer installation main body 2 is provided with the first fixed head 4 and the second fixed head 5, described the first fixed head 4 and the second fixed head 5 be arranged in parallel along left and right directions, on described the first fixed head 4 and the second fixed head 5, be relatively set with shaft hole, on described position-stopping plate 3, run through and be provided with jointed shaft 30, described position-stopping plate 3 be located between the first fixed head 4 and the second fixed head 5 and by jointed shaft 30 with the coordination hinge of shaft hole on the first fixed head 4 and the second fixed head 5.
In the above-described embodiments, shown in Fig. 1, described drawer is installed in main body 2 and is also provided with baffle plate 6 and gripper shoe 7, and described baffle plate 6 is positioned at the below of the fore-end of described position-stopping plate 3, and described gripper shoe 7 is positioned at the below of the rear end part of described position-stopping plate 3.Baffle plate 6 and gripper shoe 7, to 3 position-limiting actions of position-stopping plate, prevent that position-stopping plate 3 rotational angles are excessive.
In the above-described embodiments, shown in Fig. 1, described drawer is installed in main body 2 and is also provided with protective plate 8, described protective plate 8 be positioned at described position-stopping plate 3 fore-end front and with the fine pitch of the fore-end interval 1mm left and right of position-stopping plate 3.When drawing outside drawer 1, excessive or because inertia if exerted oneself, easily make drawer backboard 11 position-stopping plate 3 be caused to larger impulsive force or drive position-stopping plate 3 to continue outwards to move, and jointed shaft 30 is as the fixed pivot of position-stopping plate 3, be easy to because temporary impact is excessive or be out of shape excessive damage, the utility model is arranging after protective plate 8, it is mobile that drawer backboard 11 drives position-stopping plate 3 to do forward trace, can allow the fore-end of position-stopping plate 3 push up on protective plate 8, thereby reduce stressed degree and the deformation extent of jointed shaft 30.
The utility model compared with prior art, there is following beneficial effect: because drawer-bottom board and drawer-bottom board have difference in height, and the below of drawer-bottom board be provided with can before and after rotate position-stopping plate, after position-stopping plate front light, heavy design makes its rear end perk and leaning on drawer-bottom board under self gravitation effect, drawer just can be installed main body because the mutual screens effect between drawer backboard and position-stopping plate cannot depart from drawer when extracting out like this, effectively prevent that drawer from dropping, avoid drawer damage or hurt sb.'s feelings, use safe ready more.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
