Description

Technical Field

[0001] The utility model relates to the technical field of servers, in particular to a rack-type server. Background Art

[0002] A rack server is a type of server commonly used in data centers and computer rooms. It does not look like a computer, but like a switch. It has a rectangular structure and is available in different height specifications such as 1U (45cm), 2U, and 4U. It can be installed in a standard 19-inch rack and has the advantages of compact structure and small physical space. Traditional rack servers are provided with ear plates on both sides of the panel. The ear plates are generally connected to the threaded holes on the rack by screws to fix the server. The back panel of the rack server is provided with a variety of interfaces such as network cable interface, power cable interface, VGA interface, USB interface, etc. Multiple cables need to be plugged in, which causes the cables to easily collide with the inner wall of the cabinet when the rack server is pushed into the cabinet, which in turn causes damage to the cable interface or cable detachment.

[0003] In order to solve the above technical problems, a rack-mounted server is disclosed in the patent with application number 202123354475.5, which arranges anti-collision handles on both sides of the back panel and sets elastic buffer mechanisms corresponding to the anti-collision handles, so that when the rack-mounted server is pushed into the cabinet, the anti-collision handles collide with the back wall first. Under the action of the elastic buffer mechanism, the cable can be prevented from violently hitting the back wall, thereby preventing damage to the cable interface or cable falling off; however, this structure is relatively complicated, and there are many additional components on both sides of the traditional rack-mounted server, and the improvement cost is relatively high.

[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention

[0005] The utility model aims to address the deficiencies of the prior art, thereby providing a rack-mounted server with a scientific design, capable of preventing a rear connection line from violently colliding with a rear wall of a cabinet, having a simple structure and low improvement cost.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a rack-mounted server, comprising a panel arranged on the front, ear plates for cooperating with the cabinet frame are respectively arranged at both ends of the panel, and resistance-increasing columns are respectively arranged on the front sides of the two ear plates, each of the resistance-increasing columns is provided with a resistance-increasing hole along the axial direction, and a resistance-increasing rod is passed through each of the resistance-increasing holes, and a spiral protrusion is arranged on the outer peripheral surface of the resistance-increasing rod, and the spiral angle of the spiral protrusion is 40°-50°, and a spiral groove cooperating with the spiral protrusion is arranged on the inner hole wall of the resistance-increasing hole.

[0007] Based on the above, a round head is provided at one end of the resistance increasing rod extending out from the back side of the ear plate.

[0008] Based on the above, a countersunk hole is provided on the back side of the ear plate corresponding to the round head, and the round head can be completely retracted into the countersunk hole.

[0009] Based on the above, a hand wheel is provided at one end of the resistance increasing rod extending out from the front side of the ear plate.

[0010] Based on the above, a bolt mounting hole and a handle are also provided on the ear plate. The handle is provided below the resistance increasing column, and the bolt mounting hole is located outside the handle and the resistance increasing column.

[0011] The utility model has substantial characteristics and progress compared with the prior art. Specifically, when there is still a distance between the ear plate and the frame of the cabinet, the resistance-increasing rod will first contact the frame. Since the engaging surfaces of the spiral protrusion and the spiral groove are spiral, part of the impact force will be decomposed to the surroundings and part of the energy will be consumed at the same time, thereby increasing the propulsion resistance of the rack server and ensuring that the ear plate can only slowly approach the cabinet frame, thereby preventing the rear connection from colliding violently with the rear wall of the cabinet, avoiding damage to the cable interface or cable falling off. The utility model has the advantages of scientific design, ability to prevent the rear connection from colliding violently with the rear wall of the cabinet, simple structure and low improvement cost.

[0012] Furthermore, the setting of the round head can reduce the friction with the cabinet frame, making it smoother to squeeze the resistance increasing rod forward and the cabinet frame less likely to be worn; by squeezing the resistance increasing rod until the round head is retracted into the countersunk hole, the ear plate and the cabinet frame can fit together, so that the server can be installed in place.

[0013] Furthermore, the setting of the hand wheel facilitates the operation of rotating the resistance increasing rod back to the position before the impact and waiting for the next impact; the bolt mounting hole is set on the outside of the handle and the resistance increasing column so that the resistance increasing rod does not interfere with the fixing of the bolt to the server.

[0018] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0019] like Figure 1-3 As shown, a rack-mounted server includes a panel 1 arranged on the front, and ear plates 2 for cooperating with the cabinet frame are respectively arranged at both ends of the panel 1, and handles 3 and bolt mounting holes 4 are arranged on the ear plates 2; the above-mentioned equipment is common equipment in this field and does not require creative labor.

[0020] In order to prevent the cables at the rear of the rack server from colliding violently with the rear wall of the cabinet, resistance-increasing columns 5 are respectively arranged on the front sides of the two ear plates 2, each of the resistance-increasing columns 5 is provided with a resistance-increasing hole 6 along the axial direction, and a resistance-increasing rod 7 is passed through each of the resistance-increasing holes 6, and a spiral protrusion 71 is arranged on the outer peripheral surface of the resistance-increasing rod 7, and the spiral angle of the spiral protrusion 71 can be 40°-50°, and a spiral groove 61 cooperating with the spiral protrusion 71 is arranged on the inner hole wall of the resistance-increasing hole 6.

[0021] Working principle:

[0022] In the process of pushing the rack-mounted server into the cabinet, when there is still a certain distance between the ear plate 3 and the frame of the cabinet, the resistance-increasing rod 6 will first contact the frame. Since the engaging surfaces of the spiral protrusion 71 and the spiral groove 61 are spiral, part of the impact force will be decomposed to the surroundings, and part of the energy will be consumed at the same time, thereby increasing the propulsion resistance of the rack-mounted server; wherein, the smaller the spiral angle of the spiral protrusion 71, the greater the resistance. Setting it to 40°-50° can generate a certain resistance without being completely unable to push, ensuring that the ear plate 3 can only slowly approach the frame of the cabinet, thereby preventing the rear connection from colliding violently with the rear wall of the cabinet, and avoiding damage to the cable interface or cable falling off.

[0023] A round head 8 is provided at one end of the resistance increasing rod 7 extending out from the back side of the ear plate 2, and a countersunk hole 9 is provided on the back side of the ear plate 2 corresponding to the round head 8, and the round head 8 can be completely retracted into the countersunk hole 9; when in use, the round head 8 can reduce the friction with the cabinet frame, making it smoother to squeeze the resistance increasing rod 7 forward, and the cabinet frame is not easily worn. By squeezing the resistance increasing rod 7 until the round head 8 is retracted into the countersunk hole 9, the ear plate 2 can fit the cabinet frame, so that the server can be installed in place.

[0024] In order to facilitate the operation of rotating the resistance increasing rod 7 back to the position before the impact, a hand wheel 10 is provided at one end of the resistance increasing rod 7 extending out of the front side of the ear plate 2 .

[0025] In order to prevent the resistance-increasing column 5 from interfering with the installation of the bolts, the handle 3 is arranged below the resistance-increasing column 5 , and the bolt installation hole 4 is located outside the handle 3 and the resistance-increasing column 5 .

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
