[0021] Technical effects and advantages of the present invention:

[0022] 1. The folding connection part is flexible and elastic, which can ensure the connection strength and the deformation of the middle part of the metal support frame. When taking out the contained object, you only need to pull the contained object, and the contained object and the frame fixing plate can drive the metal support frame, the second sliding end rod and the telescopic connecting rod to slide along the track direction of the fixed slide rail to take out the contained object; when storing the contained object, you only need to push the contained object into the frame shell, and the folding connection part can be unfolded and folded by adaptive deformation, and the fixing and disassembly are relatively simple;

[0023] 2. The telescopic pull-out auxiliary mechanism of the present invention can be used with various specifications of contained objects and rack shells. It only needs to install the fixed slide rail on the inner wall of the rack shell and fix the contained object and the rack with a fixed plate. It has a wide range of applications.

[0024] 3. External wind enters the interior of the rack shell from the air inlet filter hole. The wind will first push the first push plate, so that the first push plate compresses the first air cavity. After the first air cavity is compressed, the air enters the interior of the second air cavity through the hose. The air pushes the second push plate to move toward the direction of the air inlet filter. At this time, the connecting rod and the external push plate move at the same time. The external push plate pushes the middle position of the air inlet filter, so that the air inlet filter bulges toward the air inlet side. When the air inlet filter bulges toward the outside of the rack shell, the opening of the end of the air inlet filter hole on the air inlet filter that is connected to the inside of the rack shell becomes smaller, while the opening of the end of the air inlet filter hole that is connected to the outside of the rack shell becomes larger. When the wind passes through the air inlet filter hole, the wind will be compressed when it flows from the end with a larger opening of the air inlet filter hole to the end with a smaller opening, and the pressure changes. The wind will be cooled when it enters the rack shell, thereby increasing the heat dissipation effect on the contained objects.

[0025] 4. Since the opening of the air inlet filter hole connected to the inside of the rack shell becomes smaller, it is difficult for large particles of impurities from the outside to enter the inside of the rack shell through the air inlet filter hole, thereby increasing the dust prevention effect;

[0026] 5. Because the opening of one end of the air inlet filter hole connected to the outside of the frame shell becomes larger, large particles of impurities are easy to enter the air inlet filter hole and cause blockage. However, due to the setting of the guide groove, when the wind enters the air inlet filter hole, it will drive the large particles of impurities to slide in the opposite direction along the guide groove and be discharged, which plays a role in preventing large particles of impurities from getting stuck and blocked inside the air inlet filter hole;

[0027] 6. When there is no wind entering the rack shell, the air inlet filter returns to the state of a vertical flat plate, and natural wind enters the rack shell from the air inlet filter hole to achieve natural heat dissipation. Since the air inlet filter hole is restored to a straight tube state at this time, natural wind can enter and exit the rack shell to the greatest extent, and large particles of impurities can be prevented from entering the interior of the rack shell;

[0028] 7. Since the diameter of the air outlet filter hole is equal to the diameter of the air inlet filter hole, when the wind enters the inside of the rack shell, the diameter of the end of the air inlet filter hole connected to the inside of the rack shell is smaller than the diameter of the air outlet filter hole. Therefore, the diameter of the particle impurities entering the rack shell with the wind is smaller than the diameter of the air outlet filter hole, and can be smoothly discharged outward through the air outlet filter hole; avoid the phenomenon that the particle impurities entering the rack shell aggregate and adhere to each other to form large particles and are blocked in the air outlet filter hole and cannot be discharged; when the particle impurities are controlled to be small, even if the particle impurities entering the rack shell have a certain degree of aggregation, they can be discharged smoothly through the air outlet filter hole to a great extent, and the particle impurities in the rack shell will not be too much to be discharged and affect the heat dissipation;

[0029] 8. When the controller receives information data of a fire and a person approaching the rack housing at the same time, it controls the electromagnet to close, causing the electromagnet to lose its magnetic attraction. At this time, the side cover and the contained object lose their limiting function, and the metal support frame uses elastic recovery to push the contained object to automatically pop out of the rack housing. When a person holds the contained object, the contained object and the rack fixing plate are quickly separated due to the pulling force, allowing the person to quickly take away the contained object with important information data, thereby reducing losses;

[0030] 9. If no personnel are close to the rack housing, the objects contained will be protected inside the rack housing, reducing the impact of fire on the objects contained, and it is relatively safe. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In Example 1, in order to solve the problem that the existing rack usually adopts the method of clamping or screwing to install the server or chassis, which is not only inconvenient to fix but also inconvenient to remove, the present invention provides a Figure 1-Figure 9 The telescopic pulling auxiliary mechanism shown in the figure includes a fixed plate 1 for a frame, a metal support frame 2 and a guide sliding plate 3. A folding connection part 9 is provided in the middle of the metal support frame 2. The folding connection part 9 is both flexible and elastic. A middle sliding block 5 is fixedly provided on the folding connection part 9. A guide sliding groove 4 is provided on the surface of the guide sliding plate 3. The guide sliding groove 4 is distributed along the length direction of the guide sliding plate 3. The middle sliding block 5 is slidably connected to the guide sliding groove 4; one end of the guide sliding plate 3 is rotatably connected to the second sliding end rod 8, and the other end of the guide sliding plate 3 is telescopically provided with a telescopic connecting rod 6. The end of the telescopic connecting rod 6 away from the guide sliding plate 3 is rotatably connected to the first sliding end rod 7. Both ends of the guide sliding plate 3 are provided with fixed slide rails 10 parallel to each other, and the ends of the first sliding end rod 7 and the second sliding end rod 8 away from each other are both slidably connected to the fixed slide rail 10. The fixed plate 1 for the frame is fixedly connected to one end of the metal support frame 2, and both ends of the metal support frame 2 are slidably connected to a fixed slide rail 10 close to the second sliding end rod 8.

[0044] The present invention also discloses a rack based on a telescopic pull-out auxiliary mechanism, comprising a rack shell 12, two fixed slide rails 10 are respectively fixedly connected to the inner walls of the two sides of the rack shell 12, when working, the contained object 11 is fixedly installed on the side of the rack fixing plate 1 away from the metal support frame 2, and the contained object 11 is stored in the rack shell 12; the metal support frame 2 is made of aluminum plate or other metal plate as a whole, but the width of the aluminum plate in the middle of the metal support frame 2 is narrowed and the height is increased, so that the folding connection part 9 has both flexibility and elasticity, which can The connection strength is guaranteed, and the middle part of the metal support frame 2 can be deformed; therefore, when taking out the contained object 11, it is only necessary to pull the contained object 11, and the contained object 11 and the frame fixing plate 1 can drive the metal support frame 2, the second sliding end rod 8 and the telescopic connecting rod 6 to slide along the track direction of the fixed slide rail 10 to take out the contained object 11; when storing the contained object 11, it is only necessary to push the contained object 11 into the frame shell 12, and the folding connection part 9 can be adaptively deformed to unfold and fold, and the fixing and disassembly are relatively simple.

[0045] The telescopic pulling auxiliary mechanism in the present invention can be used with various specifications of the contained objects 11 and the rack shell 12. It only needs to install the fixed slide rail 10 on the inner wall of the rack shell 12, and fix the contained object 11 and the rack fixing plate 1. It has a wide range of applications. An upper cover 13 and a side cover 14 are respectively opened and closed on the top and side of the rack shell 12, which facilitates the disassembly and assembly of the rack shell 12.

[0046] A heat dissipation component is also provided in the rack shell 12, and the heat dissipation component is used to dissipate heat for the contained object 11 to ensure the normal operation of the contained object 11, wherein the heat dissipation component includes an air inlet filter 21, and an air inlet groove 23 is provided on the side of the rack shell 12 away from the side cover 14, and a rubber ring 24 is fixedly provided on the periphery of the air inlet filter 21, and the periphery of the rubber ring 24 is fixed on the inner wall of the air inlet groove 23, and a plurality of air inlet filter holes 25 distributed at equal distances are provided on the air inlet filter 21; a reverse support component 22 is also provided in the rack shell 12, and the reverse support component 22 includes a first air cylinder 27, a second air cylinder 33 and an outer push plate 37, a first push plate 30 is movably provided in the first air cylinder 27, a first air cavity 29 is formed between the first push plate 30 and the interior of the first air cylinder 27, a second push plate 34 is movably provided inside the second air cylinder 33, and one side of the second push plate 34 is connected to the second air cylinder 33 A second air cavity 36 is formed inside the cylinder 33, and a connecting rod 38 is fixedly arranged on the other side. The connecting rod 38 movably passes through the outer surface of the second air cylinder 33 and is fixedly connected between the outer push plate 37. The outer push plate 37 movably fits on the surface of the air inlet filter 21, and the second air cavity 36 is connected to the first air cavity 29 through the hose 32. During operation, the external wind enters the interior of the frame shell 12 from the air inlet filter hole 25. The wind will first push the first push plate 30, so that the first push plate 30 compresses the first air cavity 29. After the first air cavity 29 is compressed, the air enters the interior of the second air cavity 36 through the hose 32, and the air pushes the second push plate 34 to move toward the direction of the air inlet filter 21. At this time, the connecting rod 38 and the outer push plate 37 move at the same time, and the outer push plate 37 pushes the middle position of the air inlet filter 21. Since the air inlet filter 21 and the rubber ring 24 can be elastically deformed, at this time, the air inlet filter 21 will be as Figure 6 As shown in the state of protruding toward the outside of the rack shell 12, when the air inlet filter 21 protrudes toward the outside of the rack shell 12, the opening of the end of the air inlet filter hole 25 on the air inlet filter 21 that is connected to the inside of the rack shell 12 becomes smaller, while the opening of the end of the air inlet filter hole 25 that is connected to the outside of the rack shell 12 becomes larger. When wind passes through the air inlet filter hole 25, the wind will be compressed when flowing from the end with the larger opening of the air inlet filter hole 25 to the end with the smaller opening, the pressure changes, and the wind will be cooled when entering the rack shell 12. Therefore, the heat dissipation effect on the accommodated object 11 will be increased.

[0047] Furthermore, since the opening of one end of the air inlet filter hole 25 communicating with the interior of the rack shell 12 becomes smaller, it is difficult for large particles of impurities from the outside to enter the interior of the rack shell 12 through the air inlet filter hole 25, thereby increasing the dust prevention effect.

[0048] Furthermore, a guide groove 26 is provided at one end of the air inlet filter hole 25 away from the interior of the frame shell 12, and a plurality of guide grooves 26 are provided, and the plurality of guide grooves 26 are distributed at equal angles along the axis of the air inlet filter hole 25. When external wind enters the interior of the frame shell 12, because the opening of one end of the air inlet filter hole 25 connected to the outside of the frame shell 12 becomes larger, large particles of impurities can easily enter the air inlet filter hole 25 and cause blockage. However, due to the setting of the guide groove 26, when the wind enters the air inlet filter hole 25, it will drive the large particles of impurities to slide in the opposite direction along the guide groove 26 and be discharged, which plays a role in preventing large particles of impurities from getting stuck and blocked inside the air inlet filter hole 25.

[0049] It should be noted that a first support plate 31 and a second support plate 35 are fixedly arranged on the side inner wall of the frame shell 12, and the first support plate 31 is fixedly supported on the bottom of the first air cylinder 27, and the second support plate 35 is fixedly supported on the bottom of the second air cylinder 33, so as to realize the positioning and support of the first air cylinder 27 and the second air cylinder 33; a spring 28 is fixedly arranged on the inner wall of the first air cylinder 27 on the side away from the first push plate 30, and the other end of the spring 28 is fixedly connected to the side of the first push plate 30 away from the second air cylinder 33, and the spring 28 is used for resetting the first push plate 30, so that when no wind enters the frame shell 12, the air inlet filter 21 returns to the state of a vertical flat plate, and the natural wind enters the interior of the frame shell 12 from the air inlet filter hole 25 to realize natural heat dissipation. Since the air inlet filter hole 25 is restored to the straight tube state at this time, the natural wind can enter and exit the frame shell 12 to the greatest extent, and large particles of impurities can also be prevented from entering the interior of the frame shell 12.

[0050] It should also be noted that the diameter of the outer push plate 37 is smaller than the diameter of the first push plate 30, ensuring that the force of the wind acting on the first push plate 30 is greater than the force acting on the outer push plate 37, so that the wind can push the first push plate 30 to compress the first air cavity 29, thereby causing the air inlet filter 21 to bulge toward the air inlet side.

[0051] The heat dissipation assembly in the present invention also includes an air duct 15 and an air outlet filter 19. The air outlet filter 19 is installed on the side cover 14. The air outlet filter 19 is provided with an air outlet filter hole 20 that connects the inside and outside of the frame shell 12. The air duct 15 is fixedly connected to a side of the side cover 14 close to the inside of the frame shell 12. A cross support frame 16 is fixedly provided on the inner wall of the end of the air duct 15 away from the side cover 14. A motor 17 is fixedly installed on the cross support frame 16. A fan blade 18 is fixedly sleeved on the rotating shaft of the motor 17; when the motor 17 is started, it drives the fan blade 18 to rotate at a high speed, thereby generating suction. Under the action of the suction, the wind force outside the frame shell 12 enters the inside of the frame shell 12 from the air inlet filter 21, and then is discharged through the air outlet filter hole 20, so as to realize the internal and external air circulation; due to the air outlet filter hole 20 The diameter is equal to the diameter of the air inlet filter hole 25. When wind enters the interior of the frame shell 12, the diameter of one end of the air inlet filter hole 25 connected to the interior of the frame shell 12 is smaller than the diameter of the air outlet filter hole 20. Therefore, as the wind enters the interior of the frame shell 12, the diameter of the particle impurities is smaller than the diameter of the air outlet filter hole 20, and can be smoothly discharged outward through the air outlet filter hole 20; avoid the phenomenon that the particle impurities entering the interior of the frame shell 12 aggregate and adhere to each other to form large particles and are blocked in the air outlet filter hole 20 and cannot be discharged; when the particle impurities are controlled to be smaller, even if the particle impurities entering the interior of the frame shell 12 are aggregated to a certain extent, they can be discharged smoothly through the air outlet filter hole 20 to a great extent, and the particle impurities in the frame shell 12 will not be too much to be discharged and affect the heat dissipation.

[0052] In Example 2, reference Fig.10As shown, an electromagnet 39 is embedded and fixed on the side inner wall of the rack shell 12, and two electromagnets 39 are provided, one electromagnet 39 is used to adsorb and fix the contained object 11, and the other electromagnet 39 is used to adsorb and fix the side cover 14; a first monitoring component 40 and a second monitoring component 41 are fixedly installed on a side of the side cover 14 away from the inside of the rack shell 12; the first monitoring component 40, the second monitoring component 41 and the electromagnet 39 are connected through a controller, the first monitoring component 40 is used to monitor dangerous situations such as fires in the environment, and a fire sensor or an infrared sensor can be used, and the second monitoring component 41 is used to monitor whether a person is close to the rack shell 12, and a radar sensor can be used. When the first monitoring component 40 detects a fire near the rack shell 12, this information data can be fed back to the controller The controller sends this data information to the background monitoring system to notify the personnel to respond to the fire in time; when the second monitoring component 41 detects that a person is approaching the rack shell 12, the second monitoring component 41 feeds this information data back to the controller. When the controller receives information data of a fire and a person approaching the rack shell 12 at the same time, it controls the electromagnet 39 to be closed, so that the electromagnet 39 loses its magnetic attraction. At this time, the side cover 14 and the contained object 11 lose their limiting effect, and the metal support frame 2 uses elastic recovery to push the contained object 11 to automatically pop out of the rack shell 12. When a person holds the contained object 11, due to the pulling force, the contained object 11 is quickly separated from the rack fixing plate 1, so that the person can quickly take away the contained object 11 that stores important information data, thereby reducing losses.

[0053] If no one is close to the rack housing 12, the contained object 11 is protected inside the rack housing 12, reducing the impact of fire on the contained object 11, and is relatively safe. Therefore, the present invention is more practical and suitable for storage and use of hosts, servers, chassis, etc.; and the bottom of the rack housing 12 is also provided with moving wheels 42, which is convenient for movement and use, breaking the limitation of fixed position use.

[0054] It should be noted that those skilled in the art can set the rack fixing plate 1 as a magnetic suction cup or a stainless steel connecting frame according to actual needs, and the contained object 11 and the rack fixing plate 1 can be used by being fixed by attraction or screws, which can be changed according to actual needs and will not be elaborated here.

[0055] The connection line between the contained object 11 and the external structure can adopt a quick connector connection line. When the contained object 11 is taken out, the connection line position can be quickly detached. This is a common existing technology and will not be described in detail here.
