Description

Novel damper for sliding door and window

Technical Field

The utility model relates to the technical field of hardware accessories, in particular to a novel damper for sliding doors and windows.

Background

In the existing market, dampers are usually arranged on some sliding doors and windows (such as wall cabinet doors and windows) to play a role in buffering, and when the door or window leaf is opened or closed, the damper is used for assisting in opening or closing, so that collision is reduced, and noise is reduced.

After long-term practical application, the structure is found to have the following serious defects and shortcomings:

(1) the damper structure is characterized in that the middle part of the shell is required to be provided with a guide groove, so that the shell can be usually formed by processing a sheet metal part, and the sheet metal part has lower structural strength relative to other materials, and is difficult to avoid deformation after long service time. If other materials are adopted for processing, the processing technology is too complex, the cost is extremely high, the production benefit is extremely low, and the material cannot be practically used as a conventional material;

(2) the damper structure is characterized in that the belt guide block is required to be placed in the guide groove, so that the shell is required to be formed by separating two halves in the production process, the poking block is placed in the two half shells, and then the two half shells are assembled and combined. The two half shells are aligned and combined, so that the requirement on the assembly process is extremely high, and the rejection rate in the assembly process is extremely high. In addition, by combining the point (1), the shell formed by assembling two halves of metal plates is easier to generate structural deformation;

(3) The damper structure is used for enabling the poking block to sink rapidly when reaching the end position of the guide groove so as to achieve rapid unhooking action, and keeping the stretching state of the stretching spring when the poking block unhooks, so that the end of the guide groove is provided with a near vertical corner, the poking block is enabled to sink when reaching the end position of the guide groove, and the stretching spring is prevented from driving the poking block to move back. However, the corner is too close to vertical, which makes it difficult to stir the stirring block to the inner side again, and if the corner is not arranged or is not vertical enough, the stirring block cannot be quickly sunk and the stirring block is prevented from moving back.

Therefore, there is a need in the art to provide a damper for sliding doors and windows that overcomes the above drawbacks.

Referring to fig. 3 and 5, the fourth embodiment of the present utility model is mainly different from embodiment 1, embodiment 2 and embodiment 3 in that: the novel damper for the sliding door and window further comprises a damping tube 9, wherein the damping tube 9 is arranged inside the shell 1, the number of the box body 2, the stirring blocks 3, the first limiting parts 4 and the second limiting parts 5 is two, and two ends of the damping tube 9 are respectively and directly connected with the two stirring blocks 3 or are respectively and indirectly connected with the two stirring blocks 3 through the two box bodies 2.

In the technical scheme of this embodiment, novel attenuator that sliding door used is equipped with two sets of box body 2, stirs piece 3, first locating part 4 and second locating part 5, can realize sliding door or window and in the two-way buffering shock-absorbing function of its both sides door frame, and specific principle is as follows:

As shown in fig. 5, when the door is closed in the left door frame direction, the novel damper for the sliding door and window moves to a certain position along with the door body when moving leftwards, the stirring block 3 on the damper can meet the blocking of the damping stirring block a, so that the stirring block 3 can not move continuously relative to the damping stirring block a, the shell 1 moves continuously in the left door frame direction along with the door body under the action of inertia, and at the moment, the damping tube 9 can generate damping buffering and damping effects, so that the moving speed of the door body is not too fast and is slowly close to the left door frame.

The same principle, when closing the door towards right door frame direction, the novel attenuator that sliding door used can follow the door body and move to the certain position when moving to the right together, stir the piece 3 on the attenuator and will meet the damping and stir the block a's the stop for stir piece 3 and can't stir piece a for the damping and continue to remove, and casing 1 then follows the door body and continue to move towards right door frame direction under the effect of inertia, and damping buffering cushioning effect can take place for damping pipe 9 this moment, makes the door body travel speed be unlikely to too fast, and is close to the right door frame slowly.

Therefore, the bidirectional damping system can realize the function of the bidirectional damping system by only arranging the two groups of box bodies 2, the poking blocks 3, the first limiting parts 4 and the second limiting parts 5, and has simple and reasonable structural design and lower cost. More specifically, the distance between the two groups of box bodies 2 can be adjusted, or the distance between the damping toggle blocks a at the top of the door frame can be adjusted according to actual requirements, so as to adapt to the width of the corresponding door body or window, thereby improving the adaptability of the product.

In the process of using the sliding door damper, the damper moves towards the door frame along with the door body when the door is closed, when the damper moves to a certain position, the poking block 3 in the damper can meet the blocking of the damping poking block a, and at the moment, the damping tube 9 in the damper has damping buffering effect, so that the moving speed of the door body is not too high, and the door body is slowly close to the door frame. However, the following technical problems are inevitably caused by such a structural design method:

in the process of closing the door, the moving speed of the door body is gradually weakened due to the buffering effect of the damping tube 9, but due to different weight of the door bodies of different types, when the door body is heavy or the moving speed of the door body is inherently slower during closing the door, the situation that the speed of the door body is weakened to zero (namely, the door body stops moving) but the door body still does not reach the door frame occurs, so that the door is not tightly closed, and the use experience of a user is seriously influenced.

Therefore, to solve this technical problem, the present embodiment discloses the following preferred scheme:

In the preferred technical scheme, when the poking block 3 is blocked by the damping poking block a, and the damping tube 9 plays a role in damping buffering and damping, the second elastic piece 10 can pull the door body to move towards the door frame continuously under the action of self-pulling force, so that the condition of loose door closing is avoided.

More specifically, the second elastic member 10 described in the above embodiment adopts a detachable structural design manner, or the tension of the second elastic member 10 is adjustable, so that the weight of the second elastic member 10 after the detachment and replacement or the weight of the second elastic member 10 after the adjustment of the tension and the door body are adapted, and the adaptability of the novel damper is further improved.

In another preferred aspect of this embodiment, the second elastic member 10 is an extension spring, and the extension spring is used to provide elastic forces with opposite directions for the two toggle blocks 3. Specifically, because the two ends of the extension spring are respectively connected with the two poking blocks 3 of the novel damper, when the door body closes towards the left side, the extension spring provides elastic tension for the poking blocks 3 at the left side; when the door body is closed towards the right side, the extension spring provides elastic tension for the poking block 3 on the right side, and finally the effect of pulling the door body to move continuously is achieved.

More specifically, because the novel damper is provided with the left toggle block 3 and the right toggle block 3, the extension spring is not required to be directly or indirectly connected with the shell 1 through other auxiliary connecting mechanisms, and the extension spring can play a role of continuously pulling the door and window to move when the sliding door and window moves leftwards or rightwards, so that the door and window is prevented from being not tightly closed.
