Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
With reference to fig. 1 to 3, the present invention provides a drawing assembly, comprising: a drawing box and a bracket 400 for supporting the drawing box.
The pull box includes: a cartridge 100 and a pull-aid module 200. The unplugging-assisting module 200 comprises: a handle 210, a rotational elastic member 220, and a locking assembly 230. The handle 210 includes: a first locking end 211, a rotation portion 212, and a first power assist end 213. The rotating portion 212 is pivotally connected to the case 100, the rotating elastic member 220 is used for driving the handle 210 to rotate along a first direction, and the locking assembly 230 is used for controlling the first locking end 211 to switch between a locked state and a free state. In this embodiment, the rotating portion 212 is located at one end of the first assisting end 213 of the handle 210 and at a side of the handle 210 facing the case 100; the first direction is clockwise in the horizontal direction.
With reference to fig. 3 to 5, the bracket 400 is provided with a limiting hole 411, and the limiting hole 411 includes: a first card end 4111 and a second card end 4112. The first clip end 4111 is located on a side of the second clip end 4112 facing a third direction, that is, the first clip end 4111 is located on a side of the second clip end 4112 away from the front panel 140. The first power assist end 213 includes: and a boss 218. The position state of the boss 218 includes: a first collision status, a second collision status and a non-collision status.
When the first locking end 211 is in the locked state, the protrusion 218 is in a first interference state. When the protrusion 218 is in the first interference state, the first locking end 211 is engaged with the locking assembly 230 to stop the rotating elastic member 220 driving the handle 210 to move, and the protrusion 218 is located at the first engaging end 4111 and abuts against the bracket 400. Therefore, when the first locking end 211 is in the locked state, the phenomenon that the first locking end 211 and the locking component 230 are clamped and failed due to the fact that the handle 210 rotates along the second direction due to vibration can be prevented, and therefore the stability of the drawing box in the locked state can be improved.
When the first locking end 211 is in the free state, the protrusion 218 is in a second interference state or a non-interference state.
When the protrusion 218 is in the second interference state, the first locking end 211 is separated from the locking assembly 230, so that the handle 210 drives the box 100 to move in the third direction through the rotating elastic member 220 and the first power assisting end 213, and the protrusion 218 is located at the second clipping end 4112 and interferes with the bracket 400. This causes the bracket 400 to apply a reaction force to the pull handle 210 via the protrusion 218 to move the drawer in a third direction relative to the bracket 400.
When the protruding portion is in a non-interference state, the first locking end 211 is separated from the locking assembly 230, and the protruding portion 218 is separated from the bracket 400, i.e. the protruding portion 218 is hidden in the drawing box. Therefore, when the drawing box is taken out, the lug boss 218 can be prevented from blocking the movement of the drawing box, and the drawing box can be taken out from the bracket conveniently.
With reference to fig. 3 to 5, the locking assembly 230 includes: a resilient member 231 and a locking member 232. The locking member 232 is pivotally connected to the box 100, and the elastic member 231 is used to drive the locking member 232 to rotate along a first direction.
When the first locking end 211 is in a locked state, the first locking end 211 is engaged with the locking element 232 to stop the rotating elastic element 220 from driving the handle 210 to move.
When the first locking end 211 is in a free state, the first locking end 211 is separated from the locking element 232, so that the handle 210 drives the box 100 to move in the third direction through the rotating elastic element 220 and the first power assisting end 213.
In the process of converting the first shrink end from the locked state to the free state, the first shrink end 211 can be separated from the locking element 232 only by driving the locking element 232 to move in the opposite direction of the first direction through an external force, so that the first shrink end 211 is in the free state. End external force right during the effect of closure 232, closure 232 drives under the self elastic action of flexible elastic component 231 closure 232 resets, drives promptly closure 232 removes the position when holding 211 joint with first closure. In the process of switching from the free state to the locked state, the first locking end 211 drives the handle 210 to move in the opposite direction of the first direction by means of an external force until the first locking end 211 is engaged with the locking element 232.
When the first locking end 211 is in a free state, the handle 210 is driven by the rotating elastic element 220 to enable the first assisting end 213 to be abutted against other external objects, so that the other external objects generate a reaction force on the first assisting end 213 to drive the box body 100 to move; the locking component 230 can control whether the rotating elastic element 220 drives the handle 210 to rotate along the first direction, the operation is simple, wherein the locking element 232 can be separated from the first condensation end by driving the locking element 232 to move in the direction opposite to the first direction, so that the rotating elastic element 220 drives the handle 210 to rotate along the first direction; the elastic member 231 can move the locking member 232 in the first direction under the action of its own elastic force until the locking member 232 is engaged with the first locking end 211.

In this embodiment, the first rotating shaft 110 and the second rotating shaft 120 are both located on a side of the front panel 140 away from the support bracket 130. When the handle 210 is moved by the force, the handle 210 rotates relative to the front panel 140 via the first rotating shaft 110. When the locking element 232 is moved by the force, the locking element 232 rotates relative to the front panel 140 via the second rotating shaft 120. The side of the front panel 140 far away from the support bracket 130 is provided with an accommodating cavity 143, the accommodating cavity 143 is located on one side of the second rotating shaft 120 far away from the first rotating shaft 110, the other end of the locking member 232 and the elastic member 231 are both located in the accommodating cavity 143, and the elastic member 231 is located on one side of the other end of the locking member 232 far away from the opening of the accommodating cavity 143.
