Detailed Description

Example one

A connecting buckle block, see figure 1, comprises a buckling part 1 and an installation part 2, wherein the first end of the buckling part 1 is connected with the first end of the installation part 2, the second end of the buckling part 1 is used for being buckled with a clamping column of a sliding rail, the second end of the installation part 2 is used for being fixedly connected with an inner rail of the sliding rail, and the buckling part 1 and the installation part 2 are integrally manufactured in an injection molding mode.

Referring to fig. 2, the fastening portion 1 is provided with a locking groove 11 for being engaged with the locking post. An opening 12 for the clip to slide into the slot 11 is provided at the second end of the engaging portion 1. A first guide surface 13 is arranged between the card slot 11 and the opening 12, the first guide surface 13 is located above the notch of the card slot 11, the first guide surface 13 extends from the upper edge of the opening 12 to the notch of the card slot 11 from top to bottom, and the first guide surface 13 is used for guiding the card column to directly slide into the card slot 11 from above the notch of the card slot 11. A second guide surface 14 is further disposed between the card slot 11 and the opening 12, the second guide surface 14 is located on one side of the notch of the card slot 11, the second guide surface 14 extends from the lower edge of the opening 12 to the notch of the card slot 11 from bottom to top, and the second guide surface 14 is used for guiding the card column to directly slide into the card slot 11 from one side of the card slot 11.

With reference to chinese patent No. CN209235360U, when the clamping column is located at the end of the guide channel away from the elastic member and separated from the connecting buckle block, the slide rail is pushed inward to move the connecting buckle block toward the clamping column, and the clamping column enters the clamping groove 11 along the first guide surface 13. When the clamping column is located at one end of the guide channel, which is close to the elastic piece, and is separated from the connecting buckle block, the sliding rail is pushed inwards to enable the connecting buckle block to move towards the clamping column, and the clamping column enters the clamping groove 11 along the second guide surface 14.

Specifically, the notch of the card slot 11 is obliquely oriented, that is, the notch of the card slot 11 is oriented at an angle of 60 to 90 degrees, preferably at an angle of 70 to 80 degrees, and in this embodiment, at an angle of 75 degrees with respect to the horizontal plane. With this design, it is on the one hand helpful for the card column to slide into the card slot 11 along the first guide surface 13 or the second guide surface 14, and on the other hand, the card column can not easily slide out of the card slot 11.

Specifically, the first guide surface 13 is a contoured surface, and the first guide surface 13 gradually extends from the upper edge of the opening 12 to the left side of the notch of the card slot 11. By adopting the design, the relative motion track of the adaptive clamping column on the sliding rail is facilitated.

In particular, the second guiding surface 14 is an inclined surface, i.e. the second guiding surface 14 has an angle with the horizontal plane, which is 0-45 degrees, preferably 20-30 degrees, in this embodiment 26 degrees. Meanwhile, the horizontal length of the second guide surface 14 is 8 to 12 mm, that is, the distance between the notch of the card slot 11 and the opening 12 is 8 to 12 mm, and in the present embodiment, the horizontal length of the second guide surface 14 is 10 mm, that is, the distance between the notch of the card slot 11 and the opening 12 is 10 mm. By adopting the design, the clamping column can be ensured to directly impact the lower position in the middle of the second guide surface 14, so that the clamping column is not easy to break the tooth part formed by the clamping groove 11 and the second guide surface 14. And, the card column can be conveniently slid into the card slot 11 along the second guiding surface 14.

Referring to fig. 3, the engaging groove 11, the opening 12, the first guiding surface 13, and the second guiding surface 14 together form a movable space, the movable space penetrates through the entire engaging portion 1, that is, the movable space extends from a first side surface of the engaging portion 1 to a second side surface of the engaging portion 1, the first side surface is located between a first end of the engaging portion 1 and a second end of the engaging portion 1, the second side surface is located between the first end of the engaging portion 1 and the second end of the engaging portion 1, and the first side surface and the second side surface are disposed oppositely.

Specifically, a protrusion 15 protrudes outward from the second side surface of the fastening portion 1, and when the connecting fastener is mounted on the inner rail of the slide rail, the protrusion 15 is inserted into the mounting hole of the inner rail. A special-shaped through hole 151 is arranged in the convex block 15, and the inner contour of the special-shaped through hole 151 is matched with the inner contour of the movable space, so that the condition of the clamping column in the movable space can be observed conveniently.

Referring to fig. 3, a convex strip 16 is provided on the inner wall surface of the movable space, the convex strip 16 extends along the inner contour of the movable space, and the convex strip 16 is provided on the side of the inner wall surface of the movable space close to the first side surface of the fastening part 1. When the clip column is in the activity space, the column part of the clip column is leaned on the convex strip 16, and the head part of the clip column is leaned on the inner wall surface of the activity space.

Referring to fig. 4, the mounting part 2 is obliquely disposed at a first end of the fastening part 1, and the mounting part 2 is inclined to a side of the fastening part 1 having the projection 15. The included angle between the mounting portion 2 and the fastening portion 1 is 0 to 10 degrees, and in this embodiment, the included angle between the mounting portion 2 and the fastening portion 1 is 5 degrees. By adopting the design, the connecting buckle block is firmly fixed on the inner rail of the slide rail.

Example two

A connection block, see fig. 5, which is different from the connection block of the first embodiment: the projection 15 does not have the through hole 151, i.e., the projection 15 seals one side of the movable space, and this design is mainly used to prevent particles such as dust from entering the connecting button block.

EXAMPLE III

The specific structure of the slide rail can refer to Chinese patent No. CN209235360U, and the difference between the slide rail and the Chinese patent No. CN209235360U is as follows: the slide rail described in this embodiment adopts the connecting buckle block described in the first embodiment or the second embodiment.
