Description

Anti-bouncing structure of sliding door buffer

Technical Field

The utility model relates to a sliding door buffer specifically is a sliding door buffer prevents jumping structure.

Background

At present, glass doors, room doors, wardrobe doors and the like in furniture are very common to use push-pull sliding doors, the sliding doors are generally two door leaves, pulleys are respectively assembled above and below each door leaf, and the sliding doors move in guide rails. In order to prevent people from being powerful for a while on the way of using the hanging sliding door, the damage of the door that does not cause such as control dynamics, the attenuator has all been used on the push-and-pull door generally, and the shifting block of dialling the attenuator is stirred in the installation on the track of push-and-pull door, when promoting the push-and-pull door and leaning on the limit, the shifting block is on the moving part of attenuator, drive the push-and-pull door and slowly move, until stopping at the frame next door of door, because the cushioning effect of attenuator, the collision takes place when making the push-and-pull door be close to the door frame, avoid because of the noise that the collision sent, the protection push-and. However, when people push the sliding door too violently or too much, due to the fact that the inertia of the sliding door is large at the moment, the poking block is matched with the damper, in the moment, one side of the sliding door can jump to generate noise, the bottom wheel of the sliding door is prone to being separated from the rail when the situation is serious, the sliding door is separated from the rail, and safety accidents occur. In addition, the mutual collision between the shifting block and the damper can also generate noise, and the shifting block or the damper is easily abraded due to long-term hard contact, so that hidden dangers are buried in subsequent sliding door operation, and therefore, an anti-jumping structure of the sliding door buffer is urgently needed to be provided.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a sliding door buffer prevent jumping structure, its is including installing the buffer main part in the door plant upper end, installs stir subassembly 2 in the door frame and hang knot or separation through the buffering slider 1 who stirs post 22 and buffer main part in locating it, realizes the buffering of sliding door and closes the door function, its characterized in that: the toggle assembly 2 comprises a base 21, a toggle column 22 and an anti-bouncing block 23 positioned at the lower end of the base 21, the toggle column 22 is in threaded connection with an adjusting hole 211 of the base 21 through an adjusting stud 221 at the upper end of the toggle column 22, a baffle column 222 at the lower end of the toggle column 22 penetrates through the base 21 to be connected with the anti-bouncing block 23 and protrudes out of the anti-bouncing block 23, a mute sleeve 3 is sleeved outside the baffle column 222 at the lower end of the toggle column 22, and the mute sleeve 3 is positioned at the lower end of the anti-bouncing block 23; the anti-bouncing block 23 is made of soft rubber, and when the shifting assembly 2 is in butt joint with the buffer main body, the anti-bouncing block 23 is positioned at the upper end of the buffer main body to limit the bouncing stroke of the anti-bouncing block.

The mute cover 3 is made of soft rubber.

The lower end of the anti-jumping block 23 is provided with a sliding table 231 which protrudes downwards from the body, and the sliding table 231 can slide along the movable groove 4 on the end surface of the buffer main body.

The sliding table 231 and the anti-bouncing block 23 are integrally formed by soft rubber through injection molding.

A pin hole 212 is formed in the base 21 in a penetrating manner, a pin 5 penetrates through the pin hole 212 to be connected with the anti-jump block 23, the anti-jump block 23 is connected and fixed with the base 21, and the pin 5 is arranged to protrude out of the upper end face of the base 21.

The upper end face of the adjusting stud 221 is provided with an adjusting groove, the toggle column 22 is rotated through the adjusting groove, and the toggle column 22 drives the anti-bouncing block 23 to move downwards, so that the relative distance between the anti-bouncing block 23 and the buffer main body is adjusted.

The working principle is as follows: when the sliding door needs to be closed, the buffer main body arranged at the upper end of the door plate moves towards the stirring assembly arranged in the door frame along the guide rail, and the stirring assembly is hung and buckled with the buffer sliding block in the buffer main body through the stirring column arranged in the stirring assembly, so that the buffering door closing function of the sliding door is realized. It should be noted that, stir the bumping post overcoat of post lower extreme and be equipped with the silence cover, when stir the post through its lower extreme bumping post and buffer slide block touch, because the silence cover is made by soft rubber, most impact has been absorbed to the silence cover, also simultaneously because be collision each other between soft material and rigid material, greatly reduced stir the post with buffer slide block when touching the noise, effectively fall and make an uproar, give the user a quiet indoor environment.

Furthermore, the silent sleeve made of soft rubber well protects the catch column at the lower end of the toggle column, avoids the rigid contact between the traditional buffer main body and the toggle column, avoids the abrasion between the buffer main body and the toggle column, protects parts and ensures the long-term stable operation of the sliding door. Not only the mute sleeve is damaged, but also the mute sleeve can be independently replaced, thereby reducing the maintenance cost.

Furthermore, the lower end of the anti-jumping block is provided with a sliding table in a downward protruding mode through the body, the sliding table slides along a sliding groove in the end face of the buffer main body, meanwhile, when the shifting assembly is in butt joint with the buffer main body, the anti-jumping block body is located above the buffer main body, the upper end face of the buffer main body is in contact with the anti-jumping block, the upward-jumping stroke of the sliding door is limited, and therefore the sliding door is prevented from derailing due to the fact that a lower guide wheel is located in a jumping amount passageway. In addition, the anti-bouncing block is made of soft rubber, and the collision contact between the buffer main body and the anti-bouncing block can not generate collision noise, so that the sliding door is stable and quiet when closed.

Furthermore, the toggle column is in threaded connection with the adjusting hole of the base through the adjusting stud at the upper end of the toggle column, when the relative height of the anti-bouncing block needs to be adjusted, the adjusting groove on the upper end face of the adjusting stud is utilized to rotate the toggle column, and the toggle column drives the anti-bouncing block to move up and down, so that the relative distance between the anti-bouncing block and the buffer main body is adjusted, the distance between the anti-bouncing block and the buffer main body reaches the optimal ideal working state, the long-term stable work of the sliding door is ensured, and the sliding door can be widely popularized.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
