Description

Rebound three-section rail

Technical Field

The utility model belongs to the guide rail field, in particular to bounce-back three section rail.

Background

Furniture such as drawer, wardrobe all can install the guide rail and slide and open the cabinet door, and cabinet door or drawer cabinet body can collide when the push-and-pull power is too violent, can damage the product, reduce the life and the noise that produces of product. Even some children push and pull the drawer to play, safety accidents are easy to happen. Therefore, the drawer with the self-locking function and the pressing rebound unlocking function meets the requirements of users.

SUMMERY OF THE UTILITY MODEL

The utility model provides a bounce-back three section rail has avoided the drawer to push back the back and has opened automatically, has improved the security performance.

For solving its technical problem, the utility model provides a bounce-back three section rail, including outer rail, well rail, interior rail, locate the rebounder and the steel ball assembly of outer rail, through the relative swing joint of steel ball assembly between outer rail, well rail, interior rail, the rebounder includes fixed block, sliding block and locates the spring between fixed block and sliding block, and the sliding block is equipped with ka tai and guide post, and the fixed block is equipped with and matches in the location hook of ka tai and match in the gliding sharp spout of guide post.

Furthermore, the positioning hook is connected to sharp spout one end, and the other end is equipped with the arc spout.

Furthermore, the clamping table and the guide post are arranged on the sliding block in a relatively swinging mode. Therefore, when the inner rail is pushed back relative to the outer rail, the guide post swings to slide into the linear sliding groove from the arc-shaped sliding rail groove, and then the clamping table swings to slide into the positioning hook from the linear sliding groove to lock the guide rail.

Further, the inner rail is provided with a pushing block used for pushing the guide post to slide, and the pushing block is provided with an auxiliary sliding groove matched with the arc-shaped sliding groove.

Furthermore, the middle rail is provided with an inner rail positioning block, and the inner rail is provided with a matched positioning stop block. Therefore, the inner rail cannot be separated from the middle rail.

Further, the outer rail is provided with a middle rail positioning baffle. Thereby, the middle rail does not separate from the outer rail.

The utility model discloses simple structure, the stable performance, it is effectual to bounce-back.

fig. 2 is an enlarged view of the bounce three tracks shown in fig. 1 at C.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses an outer rail 1, well rail 2, interior rail 3, locate outer rail 1's bounce-back ware 4 and steel ball assembly, specifically, the steel ball assembly includes a steel ball frame 51 and two steel ball strips 52, and one of them steel ball frame 51 sets up between interior rail 3 and well rail 2, and two steel ball strips 52 are located respectively between well rail 2 and outer rail 1 both sides. The rebounder 4 comprises a fixed block 41, a sliding block 42 and a spring 43 arranged between the fixed block 41 and the sliding block 42, the sliding block 42 is provided with a clamping table 64 and a guide post 65 which swing relatively, the fixed block 41 is provided with a positioning hook 61 matched with the clamping table 64 and a linear sliding groove 62 matched with the guide post 65 to slide, one end of the linear sliding groove 62 is connected with the positioning hook 61, and the other end of the linear sliding groove 62 is provided with an arc-shaped sliding groove 63. The inner rail 3 is provided with a pushing block 66 for pushing the guide post 65 to slide, the pushing block 66 is provided with an auxiliary sliding groove 67 matched with the arc-shaped sliding groove 63, and the auxiliary sliding groove 67 and the arc-shaped sliding groove 63 are in mirror symmetry; the middle rail 2 is provided with an inner rail positioning block 21, and the inner rail 3 is provided with a matched positioning stop block 31; the outer rail 1 is provided with a middle rail positioning baffle plate 11.

As shown in fig. 2, the positioning hook 61 includes a side hook a and a side hook B, and the chuck 64 is an irregular quadrangular prism in which a side face a and a side face B play a main role. When the pushing block 66 pushes the card table 64 against the positioning hook 61, the side a thereof matches with the side hook a of the positioning hook 61, whereby the card table 64 enters the positioning hook 61 from the slide way on the side of the side hook a; when the locking device is pressed to unlock, the side surface B of the clamping table 64 is matched with the side hook B of the positioning hook 61, so that the clamping table 64 slides out of the positioning hook 61 along the side hook B to realize unlocking.

In the specific use, when the drawer is closed, the spring 43 is in a compressed state, when a user needs to pull the drawer open, the user presses the drawer reversely firstly, the clamping table 64 is separated from the positioning hook 61, the drawer is unlocked, the guide column 65 slides into the arc-shaped sliding groove 63 from the linear sliding groove 62 under the action of the compression force of the spring 43 so as to push out the drawer, and the user slightly pulls the drawer open. When the user pushes back the drawer, because the spring 43 is in a relaxed state, the user needs to push forcibly at the rear stage of the drawer closing movement, the pushing block 66 on the inner rail 3 transfers force to the guide post 65, the guide post 65 slides into the linear sliding groove 62 from the arc-shaped sliding groove 63, and then the clamping table 64 slides into the positioning hook 61 to lock the drawer.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
