Description

Technical Field

[0001] The invention relates to the technical field of furniture accessories, and in particular to a buffer rebounder for a drawer slide rail. Background Art

[0002] The existing push-to-rebound drawer slide rail pushes the drawer inward for a certain distance and then triggers a buffer rebounder to make the drawer pop out automatically. However, since some users do not know or are not familiar with the built-in buffer rebounder in the drawer, the rebounder may be damaged and fail due to improper operation of the user and forced opening of the drawer.

[0003] Therefore, some buffer rebounders need to be equipped with a strong pulling protection mechanism to prevent the buffer rebounder from being damaged. Existing buffer rebounders need to be equipped with an additional protection mechanism, or by setting a deformation mechanism, but if the deformation mechanism is in a state of long-term strong pulling of the buffer rebounder, the deformation mechanism is easy to deform, so the deformation mechanism is easy to fail, and the deformation mechanism forms elastic extrusion during the strong pulling process, so there is a sense of jamming when the moving rail is forcibly pulled out, and the deformation mechanism is reset after the moving rail is pulled out.

[0004] Chinese Patent No. ZL 202010569491.7 discloses a buffer rebounder strong pull protection mechanism, which is installed on the slide seat of the buffer rebounder, including a stopper and an elastic member, a mounting groove is provided at the closed groove position of the swing hook slide of the slide seat, the stopper is installed in the mounting groove, and the upper surface of the stopper and the swing hook slide surround the closed groove position of the swing hook slide, and the slide seat is provided with a transition slide located below the closed groove position and guided to the rebound slide of the swing hook slide. The elastic member is arranged between the slide seat and the stopper, and is used to keep the stopper at the closed groove position under normal circumstances, and to move the stopper away when a strong pull operation occurs to connect the closed groove position with the transition slide. The buffer rebounder strong pull protection mechanism needs to be additionally arranged on the protection mechanism, and the protection mechanism is arranged below the slide seat, which increases the overall height of the buffer rebounder. The buffer rebounder is installed between the moving rail and the fixed rail, and its thickness is not suitable to be too thick. Summary of the invention

[0005] The present invention proposes a buffer rebounder for a drawer slide rail, which is provided with a split first movable component and a second movable component, and the first movable component is elastically connected to the second movable component. When the buffer rebounder is in a non-pressed opening state (strong pulling state), the movable rail pulls the second movable component to forcibly move on the sliding member. At this time, the sliding member and the first movable component are both in a pending state. After the movable rail is opened to a certain distance, it is unlocked with the second sliding component and passes the sliding member to open on the fixed rail. During the whole process, only the second movable component is elastically stretched by a spring, which solves the problem of the rebounder being damaged and failing due to forced opening of the drawer.

(Since the buffer rebounder is in the pressed open state, the first movable assembly will first move in the direction of the extrusion spring, so that the first bayonet of the first movable assembly will contact the block, and then the first bayonet moves to the opening guide groove under the action of the guide slope of the block).

[0009] The first movable component includes a first slider and a first swing block; the first swing block is rotatably connected to the first slider, the first slider is slidably arranged on the sliding member, and the first swing block is provided with a first latch that acts on the track groove of the sliding member.

[0011] The locking groove is provided with a guide surface, which is a guide arc surface or a guide inclined surface; When the buffer rebounder is in a normally closed state and a non-pressed open state, the second latch of the second swing block follows the movement of the movable rail along the guide surface to disengage from or be introduced into the lock groove.

[0012] The sliding member is provided with a third pendulum block; The movable rail is provided with an opening member and a closing member corresponding to the guide pin; The buffer rebounder is in a pressed-open state, and after the movable rail moves in the elastic opening direction and unlocks the second movable component, the opening action member moves along the opening direction with the movable rail and acts on the guide pin of the sliding member, so that the movable rail drives the sliding member to move and open on the shell; when the movable rail is closed, the closing action member acts on the guide pin to drive the sliding member to move in the closing direction, and the sliding member is elastically buffered and reset when it moves to the corresponding position.

[0013] The housing is provided with a limit groove, the limit groove is provided with an opening stop position, and the third pendulum block is provided with a limit pin limited on the limit groove; The buffer rebounder is in a pressed-open state. After the movable rail is elastically opened, the movable rail pushes the sliding member to move in the opening direction, and the limit pin of the third swing block moves along the limit slot, and the limit pin is finally positioned at the opening stop position, so that the sliding member is positioned and opened on the housing; The housing is provided with a first spring slot for installing a first spring and a second spring slot for installing a second spring, the first spring slot and the second spring slot are arranged adjacent to each other, the second spring slot is communicated with the limiting slot, the first movable assembly and the second movable assembly are elastically connected through the first spring, and the first movable assembly and the sliding member are elastically connected through the second spring; When the buffer rebounder is in a non-pressed opening state, the movable rail drives the second movable component to separate from the first movable component along the opening direction, the first spring is stretched, and the movable rail drives the second movable part to move along the opening direction to drive the sliding part to open on the shell, or after the movable rail runs until the second movable part is separated from the movable rail, the movable rail continues to move along the opening direction and drives the sliding part to open on the shell.

[0014] When the sliding member is opened in the housing, the limit pin of the sliding member moves along the limit groove, the third spring is in a stretched state, and the limit pin is finally positioned at the opening stop position.

[0015] The third swing block is swingably arranged on the sliding member, and the limiting groove is provided with an elastic toggle block and an elastic deformation avoidance groove for elastic deformation of the elastic toggle block.

[0016] The shell is provided with a buffer, the sliding piece is provided with a buffering action part, and a third spring is provided between the shell and the sliding piece.

[0017] The beneficial technical effects of the present invention are as follows: By providing a first movable component and a second movable component that are separated, the first movable component and the second movable component are elastically connected. When the buffer rebounder is in a non-pressed opening state (strong pulling state), the movable rail pulls the second movable component to forcibly move on the sliding member. At this time, the sliding member and the first movable component are both in a pending state. After the movable rail is opened to a certain distance, it is unlocked with the second sliding component and passes over the sliding member to open on the fixed rail. During the whole process, the second movable component is elastically stretched by a spring to avoid large deformation of the internal parts of the buffer rebounder. It also solves the problem of damage and failure of the rebounder caused by forcibly pulling the drawer open, and there is no need to additionally set up a deformation protection mechanism, thereby improving the user experience. In addition, the second movable component that is separated from the first movable component is set on the activity track space, without additionally increasing the overall thickness of the buffer rebounder.

[0018] When the buffer rebounder is in a non-pressed state, when the moving rail is forcibly pulled out, the second movable component follows the moving rail and is in an elastic separation state from the first movable component, the first spring is in a stretched state, and the sliding member can follow the second movable component to move to the corresponding position (the moving rail drives the second movable member to move in the opening direction to drive the sliding member to open on the shell), which can avoid the moving rail from being forcibly pulled out, the moving rail smoothly passes over the sliding member, and no abnormal sound is emitted during the forced pulling out of the moving rail. When the moving rail is closed, the second movable component re-engages with the moving rail, the second movable component resets with the first spring, and the sliding member is elastically buffered and reset when it is pushed to the corresponding position by the moving rail. The buffer rebounder is smooth in use, has no abnormal sound in both the pressed and non-pressed use states, and is durable. BRIEF DESCRIPTION OF THE DRAWINGS
