Background

In the existing market, a damper is usually arranged on some sliding doors and windows (such as wall cabinets and doors) to play a role in buffering, and when the door or window is opened or closed, the damper assists to open or close, so that collision is reduced, and noise is lowered.

The prior art discloses a damper for a bidirectional damping system (patent number 201721125021.1), wherein a guide groove is formed in the side surface of a shell, guide blocks protruding outwards are arranged on two sides of a toggle block, and a guide structure of the toggle block is formed by matching the guide groove with the guide blocks. After a long period of practical use, the above structure has been found to have the following serious drawbacks and disadvantages:

(1) the damper structure needs to arrange the guide groove in the middle of the shell, so that the shell can be formed by processing sheet metal parts, and the sheet metal parts are low in structural strength and difficult to avoid deformation after long service life relative to other materials. 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 needs to place the belt guide block into the guide groove, so that the shell needs to be divided into two halves to be processed and formed in the production process, the poking block is placed into the two half shells, and then the two half shells are assembled and combined. The two half shells are aligned and combined, the requirement on the assembly process is extremely high, and the rejection rate in the assembly process is extremely high. In addition, in combination with the point (1), the shell formed by assembling the two half metal plates is easy to deform;

(3) the damper structure sinks quickly when the shifting block reaches the end position of the guide groove to realize quick unhooking action, and keeps the stretching state of the stretching spring when the shifting block is unhooked, so that the end of the guide groove is provided with a corner close to the vertical corner, the shifting block sinks when reaching the end position of the guide groove, and the stretching spring is prevented from driving the shifting block to move back. However, since the corner is too close to vertical, it is difficult to shift the dial block inward again, and if the corner is not set or the corner is not vertical enough, the dial block cannot sink quickly and the dial block cannot be prevented from moving back.

Therefore, there is a need in the art for a damper for a sliding door or window that overcomes the above drawbacks.

More specifically, the distance between two sets of box bodies 2 is adjustable, or the distance between the damping toggle blocks a on the top of the door frame can be adjusted according to actual requirements, so that the width of a corresponding door body or window can be adapted, and the adaptability of the product can be improved.

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

in the door closing process, due to the buffering effect of the damping pipe 9, the moving speed of the door body is gradually weakened, but due to different weights of the door bodies of different models, when the door body is heavy or the moving speed of the door body is relatively slow originally, the door body speed is weakened to zero (namely stopped moving), but the door body still does not reach the door frame, so that the door closing is not tight, and the use experience of a user is seriously influenced.

Therefore, to solve the technical problem, the embodiment discloses the following preferred solutions:

referring to fig. 3 and 5, the novel damper for the sliding door and window further includes a second elastic member 10, the second elastic member 10 is disposed inside the housing 1, two ends of the second elastic member 10 are respectively connected to the two moving blocks 3, and the second elastic member 10 and the damping tube 9 are disposed in parallel. In the preferred technical scheme, when the toggle block 3 is blocked by the damping toggle block a and the damping tube 9 plays a damping buffering and shock absorbing role, the second elastic part 10 can pull the door body to continue to move towards the door frame under the action of self-pulling force, so that the situation that the door is not closed tightly is avoided.

More specifically, the second elastic element 10 described in the above embodiments adopts a detachable structural design, or the tension of the second elastic element 10 is adjustable, so that the detached and replaced second elastic element 10 or the second elastic element 10 with the adjusted tension adapts to the weight of the door body, thereby further improving the adaptability of the novel damper.

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

More specifically, because this novel attenuator is equipped with about two and dials piece 3, so extension spring need not directly or indirectly to be connected with casing 1 through other supplementary coupling mechanism, extension spring all can play the effect that continues pulling door and window and remove when this sliding door moves left or moves right, avoids door and window not to close tightly.

To sum up, the utility model provides a novel attenuator that sliding door used need not to set up the guide way on casing 1, so can adopt other high strength, high performance materials beyond the sheet metal component as casing 1 material, and overall structure intensity is high, stability is good, avoids leading to casing 1 to take place structural deformation under the condition of long-time use. Further, owing to need not to set up structures such as guide block and guide way, the event need not to part two halves processing with casing 1, can directly form at the integrated processing in process of production, can greatly simplify the utility model discloses an assembly process of attenuator is difficult for appearing scrapping phenomenon in the assembling process, and 1 structural strength of casing that integrated processing formed is higher, further avoids it to take place structural deformation phenomenon under the condition of long-term use.

And, the utility model provides a novel attenuator that sliding door was used sets up the perpendicular turning section that first locating part 4 replaced the guide way through the inside at casing 1, uses first pivot 6 to rotate downwards (also sink) as the center when stirring piece 3 to rotate to when with this first locating part 4 looks butt, stirring piece 3 can't remove under the effect of blockking of first locating part 4, thereby avoids stirring piece 3 to take place the rebound phenomenon under extension spring's effort. In addition, this novel attenuator that sliding door used still sets up rotatable second locating part 5 through the inside at box body 2 and realizes dialling the switching of two kinds of user state of piece, and its theory specifically is: when the shifting block 3 moves to an object at the end of the shell 1, the control end 52 of the second limiting part 5 contacts the end of the shell 1, so that the limiting end 51 is far away from the shifting block 3, and at the moment, the shifting block 3 can rotate to abut against the first limiting part 4, so that the shifting block 3 is prevented from moving back; the dial block 3 is lifted upwards, so that the limiting end of the second limiting member 5 is abutted against the dial block 3 again, and at the moment, the dial block 3 is kept at the upper position and cannot rotate under the action of the first elastic member 8, so that the box body 2 is restored to a movable state in the shell 1.

It is worth mentioning, the utility model discloses a novel attenuator can be applied to push-and-pull door, austral window, sliding sash or other push-and-pull type door and window products, for avoiding repeating, in four above embodiments, unitedly through the door body or the window form structure that the multiple push-and-pull type door and window products were referred to terms such as "door body", "door leaf".

The technical means disclosed by the scheme of the present invention is not limited to the technical means disclosed by the above embodiments, but also includes the technical scheme formed by the arbitrary combination of the above technical features. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications are also considered as the protection scope of the present invention.
