[0007] Based on the above optimization, the mounting tilt block is integrally formed on both sides of the mounting groove port, and the mounting tilt block has an inclined arc surface that gradually tilts into the mounting groove from top to bottom.

[0009] Based on the above optimization, the buffer seat is provided with a guide extension for sliding the buffer sliding fastener and a guide protrusion for auxiliary sliding and rotating of the buffer sliding fastener. The positioning part of the buffer sliding fastener is slidably connected to the guide extension, the rotating part of the buffer sliding fastener is slidably connected to the guide protrusion, and the end of the guide protrusion is provided with an inclined surface for the rotating part of the buffer sliding fastener to slide and rotate inward or outward.

[0010] Based on the above optimization, the buffer sliding fastener includes a slider and a rotating fastener. The guide extension is located at the front end of the buffer seat and has a guide groove. The guide protrusion is located on one side of the guide extension. The connecting part of the slider is slidably mounted in the guide groove and rotatably connected to the connecting part of the rotating fastener. The directional part of the slider is slidably connected to the outside of the guide extension.

[0011] Based on the above optimization, the rotating buckle is provided with a connecting block and a guide block.

[0022] The present invention will now be further described with reference to the accompanying drawings.

[0023] According to the appendix Figures 1 to 7 As shown, the built-in slide rail buffer device of this utility model includes a buffer seat 1 for mounting the fixed rail, a buffer sliding fastener 2 for engaging or disengaging with the movable rail, and a hydraulic cylinder 3 with buffer damping function. The buffer seat 1 has a mounting groove 4 for completely housing the hydraulic cylinder 3. Mounting tilt blocks 5 are provided on both sides of the port of the mounting groove 4. The hydraulic cylinder 3 slides into the mounting groove 4 from the outside in along the mounting tilt blocks 5 and can be completely enclosed within the buffer seat 1 by the elastic reset of the mounting tilt blocks 5. The piston rod of the hydraulic cylinder 3 passes through the buffer seat 1 and is engaged with the buffer sliding fastener 2.

[0024] In practical applications, the mounting tilt block 5 is integrally formed on both sides of the mounting groove 4 port, and the mounting tilt block 5 has an inclined arc surface (51) that gradually tilts into the mounting groove 4 from top to bottom. The inclined arc surface (51) and the mounting groove 4 form a buffer seat 1 for wrapping the oil cylinder 3. Furthermore, the front end of the buffer seat 1 has a through groove for the piston rod of the oil cylinder 3 to pass through and is fastened to the positioning part of the buffer sliding fastener 2.

[0025] In this way, the device adopts the method of internal hydraulic cylinder 3, so that the hydraulic cylinder 3 is wrapped in the buffer seat 1 during the pushing and pulling of the slide rail, ensuring that there is no risk of hydraulic cylinder 3 popping out, eliminating safety hazards, and making it reliable and practical.

[0026] Reference Figures 1 to 7 As shown in the diagram, further detailed, the buffer seat 1 is provided with a guide extension 11 for sliding the buffer sliding fastener 2 and a guide flange 12 for auxiliary sliding and rotating of the buffer sliding fastener 2. The positioning part of the buffer sliding fastener 2 is slidably connected to the guide extension 11, and the rotating part of the buffer sliding fastener 2 is slidably connected to the guide flange 12. The end of the guide flange 12 is provided with an inclined surface 13 for the rotating part of the buffer sliding fastener 2 to slide and rotate inward or outward.

[0027] In the optimized scheme, the buffer sliding fastener 2 includes a slider 21 and a rotating fastener 22. The guide extension 11 is located at the front end of the buffer seat 1 and has a guide groove 111. The guide protrusion 12 is located on one side of the guide extension 11. The connecting part of the slider 21 is slidably mounted in the guide groove 111 and rotatably connected to the connecting part of the rotating fastener 22. The directional part of the slider 21 is slidably connected to the outside of the guide extension 11. The directional part of the slider 21 has a snap-fit ​​groove 211 for engaging with the piston rod of the hydraulic cylinder 3. The snap-fit ​​groove 211 has a snap-fit ​​protrusion for wrapping the piston rod of the hydraulic cylinder 3.

[0028] The rotating buckle 22 includes a connecting block 221 and a guide block 222. The connecting block 221 is axially connected to the slider 21 and slidably connected within the guide extension 11. The guide block 222 is connected to the guide flange 12 and the inclined surface 13. The guide block 222 and the connecting block 221 form a snap-fit ​​guide groove 23 for sliding connection with one side of the guide extension 11.

[0029] That is, when the slide rail is opened, the movable rail engages with the rotating buckle 22, simultaneously pulling the slider 21 outward along the guide extension 11. During this period, the structure of the rotating buckle 22 and the guide extension 11 of the buffer seat 1 is simple and stable. Moreover, the locking guide groove 23 formed by them further prevents the buffer sliding buckle 2 from separating from the buffer seat 1 due to excessive load or sudden opening, strengthening the connection stability between the buffer sliding buckle 2 and the buffer seat 1. This allows the buffer sliding buckle 2 to slide smoothly and steadily on the buffer seat 1 during operation, improving the normal operation of the slide rail. When the guide block 222 of the rotating buckle 22 moves along the guide protrusion 12 to the inclined surface 13, the rotating buckle 22 rotates outward relative to the slider 21 and disengages from the movable rail, realizing the complete opening of the slide rail.

[0030] Reference Figures 1 to 7 As shown in the diagram, further detailed, the buffer seat 1 has a parallel fixing groove 6, and the fixing groove 6 is provided with a tension spring 7 for automatic closing of the movable rail. The tension spring 7 is installed on the fixing groove 6, and the two elastic ends of the tension spring 7 are respectively engaged with the end of the buffer seat 1 and the rotating part of the slider 21, so that the elastic potential energy of the tension spring 7 acts linearly on the slider 21.

[0031] When the slide rail closes, the movable rail is pushed to the designated position, where it contacts the rotating latch 22. This causes the guide block 222 to slide off the inclined surface 13, prompting the rotating latch 22 to quickly engage with the movable rail. Subsequently, under the elastic potential energy of the tension spring 7, the rotating latch 22 and the slider 21 slide linearly onto the guide extension 11, thereby automatically closing the movable rail. In this way, the three-point linear engagement structure of the tension spring 7, the slider 21, and the rotating latch 22 allows the buffer device to slide linearly with the movable rail as it opens and closes, reducing friction during closing and improving the operational stability of the slide rail.

[0032] After the rotating buckle 22 engages with the movable rail, and slides a certain distance, the hydraulic cylinder 3 is activated, and the buffering effect takes effect, so that the slide rail runs quietly and smoothly, improving the quality of the slide rail.

[0033] The above specific embodiments are only specific implementations of the present utility model with better effects. All structures that are the same as or equivalent to the built-in slide rail buffer device of the present utility model are within the protection scope of the present utility model.
