Description

Technical Field

[0001] The utility model relates to the technical field of chassis, in particular to a reinforced chassis combined back plate. Background Art

[0002] The chassis is the carrier of most computer components. The chassis is sometimes mistakenly used as a general term for the internal components of the chassis, such as the central processing unit and the motherboard. The chassis generally includes the outer shell, bracket, various switches and indicator lights on the panel, etc. As a part of computer accessories, the chassis mainly plays the role of placing and fixing various computer accessories, and plays a supporting and protective role.

[0003] A back panel is usually required when the chassis is installed and connected. However, some existing back panels are usually fixed directly to the inside of the chassis by bolts when in use. However, when the back panel is disassembled, the bolts on the back panel need to be removed before the back panel can be removed. However, this makes the disassembly of the back panel very inconvenient and complicated.

[0004] In view of the above problems, a reinforced chassis combined backplane is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a reinforced chassis combined back panel that can solve the problems of the background technology.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The reinforced chassis is combined with a back panel, so that the threaded rod drives the moving block to move outward, and then the moving block and the extrusion block move outward, so that the rubber protrusion contacts the inner wall of the chassis, so as to fix the back panel. Due to the self-locking property of the worm and the worm gear, the back panel is fixed inside the chassis, so as to fix the back panel, facilitate the combination of the back panel and the chassis, and facilitate the improvement of the stability of the connection between the back panel and the chassis, play a reinforcement effect, and avoid the loosening of the back panel and the chassis to the greatest extent.

[0014] (2) The reinforced chassis combined back plate increases the friction between the extrusion block and the chassis by setting the rubber protrusions, thereby preventing sliding, improving the reinforcement effect, and ensuring the safety and stability of use to the greatest extent.

[0015] (3) When the extrusion block and the rubber protrusion contact the chassis, the reinforced chassis combined back plate will squeeze the slide plate, thereby causing the slide plate to slide inside the moving block and squeeze the return spring, thereby facilitating buffering and preventing the chassis from being over-extruded and deformed. At the same time, it is convenient to keep the extrusion block and the rubber protrusion in contact with the inner wall of the chassis at all times, thereby preventing loosening.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0025] See also Figure 1-5 The utility model provides a technical solution: a reinforced chassis combined backplane, including a backplane 1, a heat dissipation hole 4 is opened on the surface of the backplane 1, a fixing box 2 is fixedly installed on the backplane 1, a rotating rod 9 is rotatably connected inside the fixing box 2, the rotating rod 9 passes through the backplane 1 and extends to the outside of the backplane 1, a worm 10 is fixedly installed on one end of the rotating rod 9 located inside the fixing box 2, a bracket 12 is fixedly installed inside the fixing box 2, a rotating rod 13 is rotatably connected inside the bracket 12, a worm wheel 11 is fixedly sleeved on the surface of the rotating rod 13, and the worm wheel 11 is meshingly connected with the worm 10.

[0026] When the rotating rod 9 is rotated, the worm 10 is driven to rotate, and then the worm wheel 11 is rotated, and then the rotating rod 13 is driven to rotate inside the bracket 12. Since the worm 10 and the worm wheel 11 are self-locking, it is easy to fix the rotation angle of the rotating rod 13, thereby preventing the rotating rod 13 from rotating and improving the stability of the later fixation.

[0027] The internal thread of the rotating rod 13 is connected with the threaded rod 3, and the threaded rod 3 is slidably connected inside the fixed box 2. A limiting rod 14 is fixedly installed inside the fixed box 2, and a baffle 16 is fixedly installed on one end of the limiting rod 14. A movable plate 15 is fixedly installed on the threaded rod 3, and the movable plate 15 is slidably connected on the surface of the limiting rod 14. A movable block 6 is fixedly installed on one end of the threaded rod 3. A through groove 5 is opened on the back plate 1, and the movable block 6 is slidably connected inside the through groove 5. An extrusion block 7 is slidably connected inside the movable block 6, and a rubber protrusion 8 is fixedly installed on one side of the extrusion block 7.

[0028] When the rotating rod 13 rotates, it will drive the threaded rod 3 to move outward. When the threaded rod 3 moves outward, the moving plate 15 slides on the surface of the limiting rod 14, thereby limiting the threaded rod 3, so that the threaded rod 3 can only move horizontally, thereby preventing the threaded rod 3 from rotating.

[0029] The threaded rod 3 drives the moving block 6 to move outward, and then the moving block 6 and the extrusion block 7 move outward, and then the rubber protrusion 8 contacts the inner wall of the chassis, thereby fixing the back panel 1. Due to the self-locking property of the worm 10 and the worm wheel 11, the back panel 1 is fixed inside the chassis, thereby fixing the back panel 1, facilitating the combination of the back panel 1 and the chassis, and facilitating the improvement of the stability of the connection between the back panel 1 and the chassis, achieving a reinforcement effect, and avoiding the loosening of the back panel 1 and the chassis to the greatest extent.

[0030] By providing the rubber protrusions 8, the friction between the extrusion block 7 and the chassis is increased, thereby preventing sliding, improving the reinforcement effect, and ensuring safety and stability in use to the greatest extent.

[0031] A slide plate 17 is slidably connected inside the moving block 6 , and the slide plate 17 is fixedly connected to the extrusion block 7 . A return spring 18 is fixedly installed inside the moving block 6 , and one end of the return spring 18 close to the slide plate 17 is fixedly connected to the slide plate 17 .

[0032] When the extrusion block 7 and the rubber protrusion 8 are in contact with the chassis, they will squeeze the slide plate 17, causing the slide plate 17 to slide inside the moving block 6 and squeeze the return spring 18, thereby facilitating buffering and preventing excessive extrusion of the chassis to prevent deformation of the chassis. At the same time, it is convenient to always keep the extrusion block 7 and the rubber protrusion 8 in contact with the inner wall of the chassis to prevent loosening.

[0033] Working principle:

[0034] When the rotating rod 9 is rotated, the worm 10 is driven to rotate, and then the worm wheel 11 is rotated, and then the rotating rod 13 is driven to rotate inside the bracket 12. When the rotating rod 13 rotates, it will drive the threaded rod 3 to move outward. When the threaded rod 3 moves outward, the moving plate 15 slides on the surface of the limiting rod 14, so that the threaded rod 3 restricts the threaded rod 3, so that the threaded rod 3 can only move horizontally, so that the threaded rod 3 drives the moving block 6 to move outward, and then the moving block 6 and the extrusion block 7 move outward, so that the rubber protrusion 8 contacts the inner wall of the chassis, so as to achieve the fixation of the back plate 1. Due to the self-locking property of the worm 10 and the worm wheel 11, the back plate 1 is fixed inside the chassis, so as to achieve the fixation of the back plate 1, which is convenient for the combination of the back plate 1 and the chassis, and then it is convenient to improve the stability of the connection between the back plate 1 and the chassis, which has a reinforcement effect and avoids the loosening of the back plate 1 and the chassis to the greatest extent.

[0035] When the extrusion block 7 and the rubber protrusion 8 are in contact with the chassis, they will squeeze the slide plate 17, causing the slide plate 17 to slide inside the moving block 6 and squeeze the return spring 18, thereby facilitating buffering and preventing the chassis from being over-extruded and deformed.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
