Description

Technical Field

[0001] This utility model relates to a pull-out slide rail, belonging to the field of slide rail technology. Background Technology

[0002] Current three-section slide rails consist of an outer slide rail, a middle slide rail, and an inner slide rail. The outer slide rail is fixed to the rack, the inner slide rails are fixed to both sides of the computing or power supply tray, and the middle slide rail, acting as a load-bearing rail, is positioned between the outer and inner slide rails to extend the tray's range of motion. Furthermore, the inner and middle slide rails can slide back and forth relative to each other along the outer slide rail, allowing the tray to be freely pulled out or retracted. However, existing liquid-cooled cabinet slide rails suffer from instability after being pulled out. Summary of the Invention

[0003] The purpose of this invention is to provide a pull-out slide rail that can maintain the stability of the positional relationship between the second track section and the first track section when the second track section is pulled out to the outside of the first track section.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a pull-out slide rail, comprising: a first track section and a second track section that slides with the first track section. The first track section includes a first strip-shaped body and first flanges respectively disposed on both sides of the first strip-shaped body along its length direction. The second track section, correspondingly embedded in the first track section, includes a second strip-shaped body and second flanges respectively disposed on both sides of the second strip-shaped body along its length direction. The second strip-shaped body of the second track section has an arched portion extending along its length direction and away from the first strip-shaped body, thereby forming an accommodating area between the arched portion and the first strip-shaped body of the first track section. A snap-fit ​​component is rotatably mounted on the front section of the second track section, located on the side opposite to the first strip-shaped body of the arched portion, via a pin. The rear section of the segment and the surface of the first strip body facing the arched portion are provided with a snap-fit ​​protrusion corresponding to the snap-fit ​​member. One side of the front end face of the snap-fit ​​member has an extension portion away from the pin. The end of the extension portion away from the pin is connected to the second track segment by a torsion spring, so that the rotatable snap-fit ​​member keeps the extension portion close to the second flange portion on the side of the second track segment in a first state. The extension portion has a snap-fit ​​portion that bends towards the first strip body through a through hole opened on the second strip body. When the snap-fit ​​member is in the first state, the inclined snap-fit ​​portion and the second flange portion close to the extension portion form an acute angle α1. The snap-fit ​​protrusion located in the receiving area has a groove with the same inclination angle as the snap-fit ​​portion. When the second track segment moves to the rear end position, the snap-fit ​​portion is embedded in the groove.

[0005] The following are further improvements to the above technical solution: 1. In the above scheme, the snap-fit ​​protrusion has a guide slope on the front side of the inclined groove, and the guide slope located at the front section of the snap-fit ​​protrusion forms an acute angle α2 with the second flange near the outer extension, which is smaller than the acute angle α1.

[0006] 2. In the above scheme, one sidewall of the through hole on the second strip body is set as an inclined surface, so that when the snap-fit ​​part is in the first state, the snap-fit ​​part contacts the sidewall of the through hole and the surface of the extension part facing the second flange part is parallel to and spaced apart from the second flange part.

[0007] 3. In the above scheme, the front end of the first track section has at least one stop block, and when it is in the front end position, the front end face of the second track section is in contact with the stop block.

[0008] 4. In the above scheme, the two stop blocks are spaced apart along the width direction on the first strip body of the first track section.

[0009] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: This utility model relates to a pull-out slide rail. The second rail section has a second strip-shaped body with an arched portion extending along its length and away from the first strip-shaped body, thus forming an accommodating area between the arched portion and the first strip-shaped body of the first rail section. A locking member is rotatably mounted on the front section of the second rail section, located on the side of the arched portion opposite to the first strip-shaped body, via a pin. A locking protrusion corresponding to the locking member is provided on the rear section of the first rail section, on the surface of the first strip-shaped body facing the arched portion. One side of the front end face of the locking member has an extension portion away from the pin, and the end of the extension portion away from the pin is connected to the second rail section via a torsion bar. The spring connection allows the rotatable latching member to maintain a first state in which the outer extension approaches the second flange on the side of the second track section. The outer extension has a latching portion that bends toward the first strip body through a through hole opened on the second strip body. When the latching member is in the first state, an acute angle α1 is formed between the inclined latching portion and the second flange near the outer extension. A groove with the same inclination angle as the latching portion is opened on the latching protrusion located in the receiving area. When the second track section moves to the rear end position, the latching portion is embedded in the groove, which can maintain the stability of the positional relationship between the two when the second track section is pulled to the outside of the first track section.

The first track section 1 includes a first strip body 101 and first flanges 102 respectively disposed on both sides of the first strip body 101 along its length. The second track section 2, correspondingly embedded in the first track section 1, includes a second strip body 201 and second flanges 202 respectively disposed on both sides of the second strip body 201 along its length. The second strip body 201 of the second track section 2 has an arched portion 61 extending along its length and away from the first strip body 101, thereby forming an accommodating area 62 between the arched portion 61 and the first strip body 101 of the first track section 1. A snap-fit ​​member 8 is rotatably mounted on the front section of the second track section 2, located on the side opposite to the first strip body 101 of the arched portion 61, via a pin 7. The rear section of the first track section 1, located on the side opposite to the first strip body 101 of the arched portion 61, is also rotatably mounted on the first strip body 101. A snap-fit ​​protrusion 9 corresponding to the snap-fit ​​member 8 is provided on the surface of the body 101 facing the arched portion 61. One side of the front end face of the snap-fit ​​member 8 has an extension 81 away from the pin 7. The end of the extension 81 away from the pin 7 is connected to the second track section 2 by a torsion spring 10, so that the rotatable snap-fit ​​member 8 maintains a first state in which the extension 81 approaches the second flange 202 on the side of the second track section 2. The extension 81 has a through-hole formed in the second... The through hole 203 on the strip body 201 bends towards the first strip body 101. When the snap-fit ​​member 8 is in the first state, the inclined snap-fit ​​member 82 forms an acute angle α1 with the second flange 202 near the outer extension 81. The snap-fit ​​protrusion 9 located in the receiving area 62 has a groove 91 with the same inclination angle as the snap-fit ​​member 82. When the second track section 2 moves to the rear end position, the snap-fit ​​member 82 is embedded in the groove 91.

[0014] The aforementioned snap-fit ​​protrusion 9 has a guide slope 92 located on the front side of the inclined groove 91. The aforementioned guide slope 92 located at the front section of the snap-fit ​​protrusion 9 forms an acute angle α2 with the second flange portion 202 near the outer extension portion 81, which is smaller than the acute angle α1. One sidewall of the through hole 203 on the second strip body 201 is set as an inclined surface, such that when the snap-fit ​​member 8 is in the first state, the snap-fit ​​part 82 contacts the sidewall of the through hole 203 and the surface of the extension part 81 facing the second flange part 202 is parallel to and spaced apart from the second flange part 202.

[0015] Example 2: A pull-out slide rail includes: a first track section 1 and a second track section 2 that slides with the first track section 1. The first track section 1 includes a first strip body 101 and first flanges 102 respectively disposed on both sides of the first strip body 101 along its length. The second track section 2, correspondingly embedded in the first track section 1, includes a second strip body 201 and second flanges 202 respectively disposed on both sides of the second strip body 201 along its length. The second strip body 201 of the second track section 2 has an arched portion 61 extending along its length and away from the first strip body 101, thereby forming an accommodating area 62 between the arched portion 61 and the first strip body 101 of the first track section 1. A snap-fit ​​member 8 is rotatably mounted on the front section of the second track section 2, located on the side opposite to the first strip body 101 of the arched portion 61, via a pin 7. The rear section of the first track section 1, located on the side opposite to the first strip body 101 of the arched portion 61, is also rotatably mounted with the first strip body 101. A snap-fit ​​protrusion 9 corresponding to the snap-fit ​​member 8 is provided on the surface of the body 101 facing the arched portion 61. One side of the front end face of the snap-fit ​​member 8 has an extension 81 away from the pin 7. The end of the extension 81 away from the pin 7 is connected to the second track section 2 by a torsion spring 10, so that the rotatable snap-fit ​​member 8 maintains a first state in which the extension 81 approaches the second flange 202 on the side of the second track section 2. The extension 81 has a through-hole formed in the second... The through hole 203 on the strip body 201 bends towards the first strip body 101. When the snap-fit ​​member 8 is in the first state, the inclined snap-fit ​​member 82 forms an acute angle α1 with the second flange 202 near the outer extension 81. The snap-fit ​​protrusion 9 located in the receiving area 62 has a groove 91 with the same inclination angle as the snap-fit ​​member 82. When the second track section 2 moves to the rear end position, the snap-fit ​​member 82 is embedded in the groove 91.

[0016] The front end of the first track section 1 has at least one stop block 103. When it is in the front end position, the front end face of the second track section 2 contacts the stop block 103. The two stop blocks 103 are spaced apart along the width direction on the first strip body 101 of the first track section 1.

[0017] A ball bearing frame 31 with a length shorter than the first track section 1 and the second track section 2 is provided between the first flanged part 102 and the corresponding second flanged part 202. A plurality of balls 32 are respectively installed in a plurality of ball holes 33 that are spaced apart along the length direction on the ball bearing frame 31 and respectively roll in contact with the first flanged part 102 and the second flanged part 202. The first flange portion 102 and the second flange portion 202 are each provided with a ball groove 34 extending along their length direction on the side facing the ball strip holder 31, which allows the corresponding ball 32 to be inserted. The front end of the second track section 2 and between its two second flanges 202 and the corresponding first flanges 102 are provided with a first limiting pin 41 that can move with the second track section 2. The rear end of the first limiting pin 41 is connected to the front end of the ball strip frame 31. Each of the aforementioned first limiting pins 41 is connected to the corresponding second flange portion 202 by at least one set of key and groove; A second limiting pin 42 is fixedly provided at the rear end of the first track section 1 and between its two first flanges 102 and the corresponding second flanges 202. When the second track section 2 moves to the rear end position, the rear end of the ball strip frame 31 abuts against the front end of the second limiting pin 42. The bottoms of the two aforementioned second limiting pins 42 are connected by a rib plate 5 embedded in the first strip body 101.

[0018] In use, the tray containing the computing module or power module is installed between the second track section 2 of the two oppositely arranged pull-out slide rails, and the two first track sections 1 are installed on the frame. The tray is pulled out and retracted by the reciprocating sliding of the second track section 2 in the first track section 1, so as to facilitate the loading, unloading, maintenance and other operations of the tray and computing module or power module. When the second track section 2 retracts into the first track section 1, the front end face of the second track section 2 presses against the stop block 103 on the first track section 1. The snap-fit ​​part 8, which is rotatably disposed on the second track section 2, is kept in a first state where the outer extension 81 is close to the second flange 202 on one side of the second track section 2 under the action of the torsion spring 10 and away from the snap-fit ​​protrusion 9 at the rear of the first track section 1. When the second track section 2 is pulled toward the rear end of the first track section 1, the second track section 2 slides backward relative to the first track section 1 under the action of the balls 32 on the ball bearing frame 31. The ball bearing frame 31 with the balls 32 installed moves backward until its rear end is pressed against the second limit pin 42 on the first track section 1. At this time, the second track section 2 is in a fully pulled-out state. During the aforementioned pull-out process, when the locking part 82 on the rotatable locking member 8 first contacts the guide slope 92 on the locking protrusion 9, the locking part 82 rotates under the action of the guide slope 92 on the locking protrusion 9 and squeezes the torsion spring 10 until the locking part 82 moves to the position of the inclined groove 91 on the locking protrusion 9. The locking member 8 is reset under the action of the torsion spring 10 and thus embeds into the inclined groove 91 on the locking protrusion 9, thereby locking the position of the second track section 2, so that the second track section 2 can no longer move in the forward and backward direction, ensuring the stability of its pull-out state, so as to facilitate the operation of the tray and computing module or power module pulled out of the frame without adverse interference such as position displacement.

[0019] When the above-mentioned pull-out slide rail is used, it can maintain the stability of the positional relationship between the two when the second track section is pulled to the outside of the first track section.

[0020] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
