DETAILED DESCRIPTION

[0037] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0038] like Figure 1-13 As shown, the present invention discloses a double-leaf server chassis upper cover structure, comprising a cover frame 1 and two double-leaf door leaves 3 installed in the cover frame 1; the cover frame 1 is installed on the upper part of the server chassis by riveting; locking mechanisms 4 are respectively installed on the opposite inner sides of the two double-leaf door leaves 3;

[0039] The locking mechanism 4 includes a mounting seat 41 fixedly mounted on the lower side of the edge of the biparting door leaf 3 by screws and a slider 43 slidably mounted on the mounting seat 41; a handle 42 is mounted on the slider 43; the handle 42 is a U-shaped structure, and its two ends are rotatably mounted with the front and rear ends of the slider 43;

[0040] The two mounting seats 41 have locking pins 44 slidably mounted on their inner sides and corresponding locking holes 45 . The locking pins 44 are provided with springs 46 that can retract them. The side walls of the sliders 43 are provided with guide grooves 47 that abut against the inner ends of the locking pins 44 .

[0041] When in use, the universal operating handle 42 can drive the slider 43 to slide forward and backward on the mounting seat 41, so that the guide grooves 47 of different depths abut against the locking pin 44 for guidance. When the inner end of the locking pin 44 abuts against the shallow position of the guide groove 47 (the spring 46 provides a retraction force), the locking pin 44 is in an extended state (protruding from the surface of the mounting seat 41), and is inserted into the locking hole 45 on the corresponding locking mechanism 4 (mounting seat 41), so as to achieve reliable locking of the two split door leaves 3; when the inner end of the locking pin 44 abuts against the deep position of the guide groove 47 (the spring 46 provides a retraction force), the locking pin 44 is in a retracted state (retracted into the surface of the mounting seat 41), and is disengaged from the corresponding locking hole 45, so as to achieve convenient unlocking of the two split door leaves 3. The overall structure is simple, and reliable locking and convenient unlocking of the two split door leaves 3 can be achieved, and the operation is convenient. A double-door structure is adopted at the top of the server chassis, so the server chassis can be opened without removing the upper cover, which is convenient for maintenance and display of the internal server. It is practical and avoids the overall removal of the upper cover, thus improving work efficiency and saving manpower and material resources.

[0042] The double-leaf door leaf 3 is provided with a handle fitting groove 32 for fitting and positioning the handle 42. The shape of the handle fitting groove 32 matches the shape of the handle 42, and a position avoidance groove is extended in the unlocking direction for the handle 42 to slide; in the locked state, the handle 42 can be fitted in the handle fitting groove 32 to position the handle 42; when unlocking is required, the handle 42 is flipped out of the handle fitting groove 32, and the handle 42 is operated to slide in the direction of the position avoidance groove to achieve unlocking; and the position avoidance groove can limit the maximum sliding stroke of the handle 42 to ensure the reliability of use.

[0043] like Figure 2 As shown, the double-leaf door leaf 3 is also provided with an operating groove 33 connected to the handle fitting groove 32. The operating groove 33 is located inside the middle of the front-rear direction section of the handle fitting groove 32, which can facilitate the lifting and operation of the handle 42, ensuring the convenience of use.

[0044] like Figure 7-8 As shown, a positioning block 34 is provided in the handle fitting groove 32, and the positioning block 34 is arranged opposite to the operation groove 33. A notch is provided on the handle 42 to fit with the positioning block 34, and a positioning rod 48 is provided on the outer edge of the notch. The positioning rod 48 is in the shape of a round rod, and the positioning block 34 and the corresponding side wall of the handle fitting groove 32 are respectively provided with positioning protrusions 35 that can clamp and position the positioning rod 48. In the locked state, the handle 42 is fitted in the handle fitting groove 32, the notch on the handle 42 is clamped with the positioning block 34, and the positioning rod 48 is clamped with the positioning protrusion 35, so that the handle 42 can be reliably positioned, and the handle 42 can be prevented from being arbitrarily disengaged from the handle fitting groove 32, thereby achieving reliability in use.

[0045] The sliders 43 of the left and right locking mechanisms 4 slide in opposite unlocking directions. When unlocking, the left and right handles apply force in opposite directions to achieve convenient operation. When locking, the handles 42 are aligned on the left and right to achieve symmetry when locking, and the design is more coordinated. An unlocking mark is set on the unlocking direction of the biparting door leaf 3 to avoid damage to components caused by reverse operation.

[0046] like Figure 3 , 4 As shown in Figures 6 and 7, the cross section of the slider 43 is in a convex shape, and the mounting seat 41 is provided with a slideway that runs through the front and back and is adapted to the cross section of the slider 43. The slider 43 is mounted on the mounting seat 41 by sliding forward and backward through the slideway, ensuring the accuracy and reliability of the operation and effectively preventing the slider 43 from coming out of the mounting seat 41.

[0047] like Figure 6 As shown, the guide groove 47 includes an extended abutment surface, a transition guide surface and a retracted abutment surface connected in sequence, and a limit protrusion is provided between the extended abutment surface and the transition guide surface, which can effectively prevent automatic retraction (automatic sliding). The extended abutment surface and the retracted abutment surface are in the front-to-back direction, and the depth of the retracted abutment surface is greater than the depth of the extended abutment surface. The transition guide surface is an inclined plane, which plays a smooth transition and ensures the smoothness of the extension and retraction action of the locking pin 44.

[0048] like Figure 10-12 As shown, a mounting guard plate 11 is provided on the lower side of the inner edge of the upper cover frame 1. The mounting guard plate 11 is in a circular shape. A frame is bonded on the mounting guard plate 11. The split door leaf 3 is rotatably mounted on the inner side of the frame. The frame includes two U-shaped frame members 2 for mounting; the ends of the frame members 2 are provided with positioning shafts 21 and positioning holes 22 for positioning and mounting; the front and rear ends of the outer sides of the split door leaf 3 are provided with door leaf mounting shafts 31, and the corners of the frame members 2 are provided with door leaf mounting holes 23 for inserting with the door leaf mounting shafts 31. During installation, the split door leaf 3 and the frame member 2 are first inserted through the door leaf mounting shafts 31 and the door leaf mounting holes 23, and at the same time, the two frame members 2 are positioned and inserted through the positioning shafts 21 and positioning holes 22 corresponding to the end faces to form a split door as a whole with a frame; then, the whole is placed on the inner circle of the upper cover frame 1, and the frame is bonded and fixed by the mounting guard plate 11. The assembly structure is simple, convenient and reliable to use, and easy to implement.

[0049] Among them, the frame and the double-leaf door leaf 3 are all made of transparent material. Selected as a transparent PVC material, when the door is not opened, the internal structure and operating status of the server can be clearly seen through the transparent double-leaf door leaf 3, which has good practicality.

[0050] like Fig.11As shown, the installation guard plate 11 is provided with a limit plate 12 capable of supporting the front and rear ends of the buckle seam of the two biparting door leaves 3. When the biparting door leaves 3 are buckled, the limit plate 12 supports the front and rear ends of the inner sides of the biparting door leaves 3 to prevent the biparting door leaves 3 from rotating downward and opening, thereby ensuring the reliability of the installation of the biparting door leaves 3 and the safety of use.

[0051] The left edge of the right-side split door leaf 3 is provided with a protective edge that can be pressed against the right edge of the left-side split door leaf 3. The door opening sequence is defined, and the right-side split door leaf 3 must be opened first and then the left-side split door leaf 3 to ensure the reliability of the locking of the split door leaf 3.

[0052] The double-leaf server case upper cover structure has a simple overall structure, can realize reliable locking and convenient unlocking of the two double-leaf door leaves 3, and is easy to operate. The double-leaf door structure is adopted at the top of the server case, and the server case can be opened without removing the upper cover, which is convenient for maintenance and display of the internal server, has good practicality, avoids overall removal of the upper cover, improves work efficiency, and saves manpower and material resources. When in use, the universal operating handle 42 can drive the slider 43 to slide back and forth on the mounting seat 41, so that the guide grooves 47 of different depths abut against and guide the locking pin 44. When the inner end of the locking pin 44 abuts against a shallow position of the guide groove 47 (the retraction force is provided by the spring 46), the locking pin 44 is in an extended state (protruding from the surface of the mounting seat 41), and is engaged with the locking hole 45 on the relative locking mechanism 4 (mounting seat 41), thereby realizing reliable locking of the two double-leaf door leaves 3; when the inner end of the locking pin 44 abuts against a deeper position of the guide groove 47 (the retraction force is provided by the spring 46), the locking pin 44 is in a retracted state (retracted into the surface of the mounting seat 41), and is disengaged from the corresponding locking hole 45, thereby realizing convenient unlocking of the two double-leaf door leaves 3.
