Description

Technical Field

[0001] This utility model relates to the field of MINI back panel technology, and in particular to a MINI back panel device with high adaptability. Background Technology

[0002] A MINI backplane is a key component widely used in communication, server, and industrial electronic equipment. It is typically mounted vertically within a chassis or rack to carry and connect various functional daughter cards.

[0003] The vertically mounted MINI back panel has the following problems in height adaptation: the mounting point height of most MINI back panels is fixed, which is inconvenient to adjust and greatly limits its versatility; some adjustable MINI back panels use long holes with multiple screws or complex sliding rails to achieve lifting. When installed vertically, adjustment often requires disassembly, then manually lifting and aligning the MINI back panel, and finally re-tightening multiple screws. The whole process is very cumbersome and there is a risk of unstable installation.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of this disclosure and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] This invention provides a height-adaptive MINI back panel device with a simple structure that allows for quick adjustment of the MINI back panel height, improving practicality and effectively solving the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A height-adjustable MINI back panel device includes a MINI back panel and a height adjustment mechanism; the height adjustment mechanism includes: The connecting plate has several fixing teeth arranged longitudinally side by side on the side facing the MINI back panel. The fixing teeth are right-angled trapezoids. The lower base of the right-angled trapezoid is connected to the connecting plate, the upper base faces the connecting plate, and the hypotenuse is above the right-angle side. The hypotenuse and right-angle side of two adjacent fixing teeth form a space. Both ends of the connecting plate extend to the side of the MINI back panel and connect to the MINI back panel. A fixed frame is fixed to an external support surface, and a fixed shaft is rotatably connected to it. At least one end of the fixed shaft is fixedly connected to one end of a swing arm, and the other end of the swing arm is provided with a locking shaft. A connecting plate slides vertically on the fixed frame. When the locking shaft is in the space, the MINI backplate and the fixed frame are relatively stationary, and at this time the other end of the swing arm is tilted downward.

[0007] Furthermore, the end where the upper base connects to the hypotenuse is rounded.

[0008] Furthermore, swing arms are fixedly connected to both ends of the fixed shaft.

[0009] Furthermore, a through hole is provided at the other end of the swing arm, through which the locking shaft passes. One of the locking shafts has a threaded rod, and the other locking shaft has a threaded groove. The two locking shafts are threaded together. Each locking shaft has an anti-loosening part at the other end.

[0010] Furthermore, at least one end of the fixed shaft is fitted with a torsion spring, which provides torque to the other end of the swing arm tilting downwards.

[0011] Furthermore, the mounting bracket is fixed with a limit plate, and the limit plate is threaded with a bolt. When the MINI back plate and the mounting bracket are relatively stationary, the top of the bolt abuts against the swing arm.

[0012] Furthermore, at least one end of the fixed shaft is fixed with an extension arm, which has a non-slip handle.

[0013] Furthermore, the fixed frame is fixed with a support plate, and the support plate is threadedly connected with two bolts, which are located above the swing arm.

[0014] The technical solution of this utility model can achieve the following technical effects: The height adjustment mechanism of this device achieves fast, labor-saving and reliable height adjustment through the ingenious cooperation of the unique right-angled trapezoidal fixing teeth, the swing arm and the locking shaft. The user only needs to push the MINI back panel upward to the desired height and then release it to automatically lock it. The whole process does not require any tools, which greatly improves the convenience of equipment installation and maintenance. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0019] This application provides a height-adaptive MINI back panel device, including a MINI back panel 1 and a height adjustment mechanism; the height adjustment mechanism includes: Reference Figures 1-4 The connecting plate 2 has several fixing teeth 3 arranged longitudinally side by side on the side facing the MINI back panel 1. The fixing teeth 3 are right-angled trapezoids. More specifically, the right-angled trapezoids are arranged vertically. The lower base 4 (that is, the longer base) of the right-angled trapezoid is connected to the connecting plate 2, the upper base 5 faces the connecting plate 2, and the hypotenuse 6 is above the right-angle side 7. The hypotenuse 6 and right-angle side 7 of two adjacent fixing teeth 3 form a space. The two ends of the connecting plate 2 extend to the side of the MINI back panel 1 and connect to the MINI back panel 1. A fixed frame 8 is fixed to an external support surface by bolts, etc., and a fixed shaft 9 is rotatably connected to it. At least one end of the fixed shaft 9 is fixedly connected to one end of a swing arm 10, and the other end of the swing arm 10 is provided with a locking shaft 11; see reference. Figure 3 The connecting plate 2 slides vertically on the fixed frame 8. More specifically, a track 12 is fixed on the connecting plate 2, and the fixed frame 8 has a groove for the track 12 to slide. When the locking shaft 11 is in the space, the MINI backplate 1 and the mounting bracket 8 are relatively stationary. At this time, the other end of the swing arm 10 is tilted downwards. More specifically, refer to... Figure 3 and Figure 4At this time, the fixed frame 8 and the connecting plate 2 are relatively stationary. Under the action of gravity, the MINI back plate 1 and the connecting plate 2 tend to move downward relative to the fixed frame 8 and the locking shaft 11. However, at this time, the locking shaft 11 abuts against the right-angle side 7 and will not exert a force on the swing arm 10 to rotate clockwise, thereby achieving the purpose of locking. In practical use, the MINI backplate 1 is installed vertically, and the mounting bracket 8 is fixed to the external support surface by bolts, etc. After all components are installed, the desired result is achieved. Figure 4 In the state shown, the MINI back panel 1 is stationary. When it is necessary to raise the position of the MINI back panel 1, push the MINI back panel 1 and the connecting plate 2 upward. During the upward movement of the connecting plate 2, the swing arm 10 and the locking shaft 11 will first rotate clockwise around the fixed shaft 9. When the swing arm 10 and the locking shaft 11 rotate clockwise around the fixed shaft 9, the relative position of the locking shaft 11 and the fixed tooth 3 changes. When the fixed tooth 3 can no longer push the locking shaft 11 to rotate clockwise, the locking shaft 11 moves downward relative to the fixed tooth 3, thus reaching the next fixed tooth 3. At this time, gradually remove the pushing force on the MINI back panel 1. The MINI back panel 1 and the connecting plate 2 descend. The locking shaft 11 is in space under the action of gravity and gradually abuts against the right angle side 7, thus achieving the purpose of fixing the MINI back panel 1.

[0020] As a preferred embodiment of the above, refer to Figure 3 The upper bottom 5 and the inclined side 6 are connected at one end with rounded corners. The rounded corners provide a smooth transition guide for the movement of the locking shaft 11 between the teeth of the fixed teeth 3, which significantly reduces friction, impact and noise during the operation and avoids possible jamming.

[0021] As a preferred embodiment of the above, refer to Figure 3 Both ends of the fixed shaft 9 are fixedly connected to the swing arms 10; the symmetrical layout of the swing arms 10 on both sides allows the locking shaft 11 to synchronously and evenly bear the load from the MINI back plate 1 and the connecting plate 2, preventing the locking shaft 11 from deforming.

[0022] As a preferred embodiment of the above, refer to Figure 3 The other end of the swing arm 10 has a through hole, through which the locking shaft 11 passes. One of the locking shafts 11 has a threaded rod, and the other locking shaft 11 has a threaded groove. The two locking shafts 11 are threaded together. The other end of each locking shaft 11 is equipped with an anti-disengagement part 13. More specifically, the anti-disengagement part 13 is a component with a size larger than the through hole to prevent the locking shaft 11 from disengaging from the through hole. In the above embodiment, the structure makes the two locking shafts 11 a separable whole. When maintenance or replacement is required, the locking shaft 11 can be easily removed from the rocker arm 10 simply by unscrewing the threaded connection. Disassembly is extremely convenient and greatly simplifies the maintenance process.

[0023] As a preferred embodiment of the above, refer to Figure 1 and Figure 3 At least one end of the fixed shaft 9 is fitted with a torsion spring 14, which provides torque to the other end of the swing arm 10 tilting downwards; In the above embodiment, the two ends of the torsion spring 14 are connected to the fixed frame 8 and the swing arm 10 respectively. The torsion spring 14 provides a continuous and directional reset force for the swing arm 10 and the locking shaft 11, ensuring that the locking shaft 11 can automatically return to the space during the adjustment process, effectively preventing the problem of incomplete locking due to gravity failure or shaking.

[0024] As a preferred embodiment of the above, refer to Figures 2-3 The fixed frame 8 is fixed with a limit plate, and the limit plate is threaded with a bolt 15. When the MINI back plate 1 and the fixed frame 8 are relatively stationary, the top of the bolt 15 abuts against the swing arm 10. In the above embodiment, by rotating the bolt 15, the relative position of the bolt 15 and the swing arm 10 can be adjusted. When the top of the bolt 15 abuts against the swing arm 10, the swing arm 10 cannot continue to rotate downward, which can effectively limit the swing range of the swing arm 10 near the locked position.

[0025] As a preferred embodiment of the above, refer to Figures 2-3 At least one end of the fixed shaft 9 is fixed with an extension arm 16, which has a non-slip handle. By gripping the non-slip handle and rotating it, the fixed shaft 9, the swing arm 10, and the locking shaft 11 can be rotated, thereby controlling the relative position of the locking shaft 11 and the fixed tooth 3. In the above embodiment, when it is necessary to adjust the height of the MINI back panel 1 downwards, hold the MINI back panel 1 with one hand and grip the anti-slip handle with the other hand. Adjust the relative position of the fixing tooth 3 and the locking shaft 11 by coordinating the two hands, so that the locking shaft 11 is disengaged from the space, and then adjust the height of the MINI back panel 1 downwards; after the adjustment is completed, release the anti-slip handle.

[0026] As a preferred embodiment of the above, refer to Figures 2-3 The fixed frame 8 is fixed with a support plate, and the support plate is threaded with bolt 2 17, which is located above the swing arm 10. In the above embodiment, the relative position of the second bolt 17 and the swing arm 10 can be adjusted by rotating the second bolt 17, thereby limiting its angle and preventing the rotation angle from being too large.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
