Description

Technical Field

[0001] This utility model relates to the field of server slide rail technology, and in particular to a universal server slide rail locking structure. Background Technology

[0002] Slide rails, as a common mechanical component, are widely used in various scenarios requiring sliding functionality, such as server racks. The server chassis is connected to the rack via slide rails, allowing it to be pulled out or moved in. To improve the ease of connection between the server and the slide rail, some existing server chassis have limit pins on both sides, and limit grooves on the slide rail. These limit pins and grooves engage with locking mechanisms for quick locking. However, the limit grooves on slide rails typically come in various sizes, such as V-shaped or J-shaped, each requiring a different locking structure. This necessitates multiple locking structures to meet the needs of different limit holes, resulting in poor versatility in the locking mechanisms. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides a universal servo slide rail locking structure that is applicable to a variety of different limit slots and has better versatility.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A universal servo rail locking structure includes a rail body with a limiting groove, and a locking member disposed on one side of the limiting groove and rotatably connected to the rail body. The upper end of the limiting groove is connected to the upper edge of the rail body. The rail body has an arc-shaped guide groove, the center of which coincides with the rotation point of the locking member. The locking member has a guide pin extending into the guide groove. The arc-shaped guide groove includes a first groove and a second groove connected to the end of the first groove near the limiting groove. The width of the second groove is smaller than that of the first groove. Two guide pins are configured, namely a first guide pin and a second guide pin. The first guide pin cooperates with the first groove, and the second guide pin cooperates with the second groove. The guide pins are detachably connected to the locking member. In use, one of the guide pins is selected to connect to the locking member. An elastic element is provided between the locking member and the rail body to drive the locking member to rotate towards the limiting groove and lock the limiting pin.

[0005] By adopting the above technical solution, a first guide pin or a second guide pin is selected according to different limiting grooves to satisfy the locking after the limiting pin enters the limiting groove; this locking structure has strong versatility and lower cost.

[0006] Preferably, the locking element is rotatably connected to the rail body via a rotating shaft, and the elastic element is configured as a torsion spring. The torsion spring is sleeved on the rotating shaft, with one end of the torsion spring abutting against the rail body and the other end abutting against the guide pin. By using the cooperation of the torsion spring and the rotating shaft, the rotation passes through the torsion spring to position it, making the installation of the torsion spring more convenient and stable.

[0007] Preferably, the outer surface of the locking element is provided with a groove. The groove allows a finger to be inserted into the groove to move the locking element to unlock it, making unlocking more convenient.

[0008] Preferably, the upper end of the locking member extends towards one side of the limiting groove to form a lug. When the first guide pin is selected to connect with the locking member, under the action of the elastic member, the lug enters the limiting groove and locks the limiting pin through the lower side of the lug. The limiting pin is locked and limited by the lug.

[0009] Preferably, the upper end of the locking member is provided with an inclined guide portion on the side facing the limiting groove; when the first guide pin is connected to the locking member, when the limiting pin enters the limiting groove and applies force to the guide portion, the locking member automatically rotates to avoid it, so that the limiting pin smoothly enters the limiting groove.

[0010] Preferably, when the second guide pin is connected to the locking member, the locking member is manually moved to open the limiting groove, allowing the limiting pin to enter the limiting groove. When the limiting pin is fully inside the limiting groove, the locking member rotates under the action of the elastic member, causing the guide portion to lock and limit the limiting pin. The center point of the second guide pin is located below the line connecting the center points of the limiting pin and the center point of the locking member. After the limiting pin is locked, the position of the limiting pin and the position of the locking member are in a self-locking state. Only manual unlocking can remove the limiting groove, thereby improving the locking stability of the limiting groove.

[0011] Preferably, the limiting groove is configured as either a V-shaped groove or a J-shaped groove, the distance from the bottom end of the J-shaped groove to the rotation point of the locking member is configured as a, and the distance from the bottom end of the V-shaped groove to the rotation point of the locking member is configured as b, where b < a; when the limiting groove is a V-shaped groove, a first guide pin is used to cooperate with the first groove body; when the limiting groove is a J-shaped groove, a second guide pin is used to cooperate with the second groove body.

[0012] Therefore, this utility model has the beneficial effect of being adaptable to various different limiting grooves and having strong versatility. Attached Figure Description

[0021] To make the technical problem to be solved, the technical solution, and the beneficial technical effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the scope of protection of the present utility model.

[0022] It should be understood that the terms "first," "second," etc., used herein are for descriptive purposes only and should not be construed as indicating or implying relative importance, nor should they be construed as implicitly specifying the number of technical features indicated. Features specified as "first" or "second" may expressly or implicitly indicate that at least one of those features is included.

[0023] like Figure 1 , Figure 2 and Figure 7The diagram illustrates a general-purpose servo slide rail locking structure, comprising a rail body 1 with a limiting groove 100, and a locking member 2 disposed on one side of the limiting groove 100 and rotatably connected to the rail body 1. The upper end of the limiting groove 100 is connected to the upper edge of the rail body 1. The rail body 1 is provided with an arc-shaped guide groove 11, the center of which coincides with the rotation point of the locking member 2. The locking member 2 is provided with a guide pin 12 extending into the guide groove. The arc-shaped guide groove 11 includes a first groove 111 and a second groove 111 connected to the end of the first groove 111 near the limiting groove 100. The groove 112 has a width smaller than that of the first groove 111; the guide pin 12 is configured as two pins, namely a first guide pin 121 and a second guide pin 122, wherein the first guide pin 121 cooperates with the first groove 111 and the second guide pin 122 cooperates with the second groove 112; the guide pin 12 is detachably connected to the locking member 2, and in use, one of the guide pins 12 is selected to connect to the locking member 2; an elastic member 3 is provided between the locking member 2 and the rail body 1 to drive the locking member 2 to rotate in the direction of the limiting groove 100 and lock the limiting pin 5.

[0024] The locking member 2 is rotatably connected to the rail body 1 via a rotating shaft 4. The elastic member 3 is configured as a torsion spring 30, which is sleeved on the rotating shaft 4. One end of the torsion spring 30 abuts against the rail body 1, and the other end of the torsion spring 30 abuts against the guide pin 12. The outer side of the locking member 2 is provided with a groove 20.

[0025] The limiting groove 100 is configured as either a V-shaped groove 101 or a J-shaped groove 102. Figures 1-4 The limiting groove in the middle adopts a V-shaped groove 101. Figures 5-8 The limiting groove in the middle adopts the following configuration; the distance between the bottom end of the J-shaped groove 101 and the rotation point of the locking member 2 is configured as a (e.g., Figure 5 (As shown by the dashed line in the middle), the distance from the bottom end of the V-groove 102 to the rotation point of the locking member 2 is configured as b (e.g., Figure 1 (as shown by the dashed line in the middle), where b < a; when the limiting groove 100 is a V-shaped groove 101, the first guide pin 121 is used to cooperate with the first groove body 111; when the limiting groove 100 is a J-shaped groove 102, the second guide pin 122 is used to cooperate with the second groove body 112.

[0026] like Figure 1 and Figure 2 As shown, the upper end of the locking member 2 extends towards one side of the limiting groove 100 to form a lug 21. When the first guide pin 121 is selected to connect with the locking member 2, under the action of the elastic member 3, the lug 21 enters the limiting groove 100 and locks the limiting pin 5 through the lower side of the lug 21. The upper end of the locking member 2 is provided with an inclined guide portion 22 on the side facing the limiting groove 100; as Figure 4As shown, when the first guide pin 121 is connected to the locking member 2, when the limiting pin 5 enters the limiting groove 100 and applies force to the guide part 22, the locking member 2 automatically rotates to avoid the limiting pin 5, allowing it to smoothly enter the limiting groove 100.

[0027] like Figure 5 As shown, when the second guide pin 122 is connected to the locking member 2, the locking member 2 is manually moved to open the limiting groove 100 so that the limiting pin 5 enters the limiting groove 100; when the limiting pin 5 is fully entered into the limiting groove 100, the locking member 2 rotates under the action of the elastic member 3 and causes the guide part 22 to lock and limit the limiting pin 5 towards the limiting pin 5, and the center point of the second guide pin 122 is located below the center line connecting the center point of the limiting pin 5 and the center point of the locking member 2.

[0028] The V-shaped groove and J-shaped groove in this embodiment are merely examples of two typical limiting grooves on the rail body 1. These two types of limiting grooves include two categories: one type has a small distance between the bottom of the limiting groove and the rotation point of the locking component, such as the V-shaped groove; the other type has a large distance between the bottom of the limiting groove and the rotation point of the locking component, such as the J-shaped groove. As long as the limiting groove meets the characteristics of these two types of grooves, it can be locked and limited by the locking structure in this embodiment.

[0029] This locking mechanism only requires selecting the corresponding first guide pin or second guide pin according to different limiting grooves. When the distance between the bottom of the limiting groove and the rotation point of the locking component is small (e.g., V-shaped groove), the first guide pin is selected to cooperate with the first groove body. When the distance between the bottom of the limiting groove and the rotating part of the locking component is large (e.g., J-shaped groove), the second guide pin is selected to cooperate with the second groove body. The locking component does not need to be replaced and is universal. This locking structure makes the parts more versatile, reduces the types of parts, and lowers the cost of the locking structure.
