Technical Field

[0001] The present invention relates to the technical field of computer protection, and particularly to a computer protection device for weak current engineering. Background Art

[0002] Weak current engineering is a part of modern construction projects. The computer protection device for weak current engineering is a device that protects a computer from the external environment when the computer is transported at a construction site, protects the internal data of the computer, increases the service life of the computer used in weak current engineering, and reduces the damage of the computer during transportation.

[0003] The patent with the patent number CN110598490B discloses a computer mainframe protection device with moisture-proof and impact-proof functions, including a housing, a main protection plate, a top plate, a secondary protection plate, a main limiting plate, a secondary limiting plate, a limiting spring, a telescopic spring, a secondary protection groove, a drawer, a connecting rod, a pull ring, a sliding rod, a fixed rod, a moving block, a pull rod, an arc plate, a protection spring, a rotating rod, a connecting block, a connecting spring and a convex block. The housing is symmetrically provided with main protection grooves on both corresponding sides, and a secondary protection groove is provided at one end of the housing. This patent fixes the mainframe by squeezing the limiting spring and the telescopic spring with the main protection plate and the secondary protection plate. After being compressed, the limiting spring and the telescopic spring generate a reverse elastic force, which pushes the main protection plate or the secondary protection plate to move away from the placement groove, thereby fixing the mainframe. The air inside the mainframe is dehumidified by a desiccant to achieve the moisture-proof function, protect the mainframe, save the time consumed for repairing the mainframe, and improve work efficiency.

[0004] However, the current computer mainframe protection device with moisture-proof and impact-proof functions has the following problems: When this moisture-proof and impact-proof computer mainframe protection device is in use, since the computer needs to be carried to a designated construction site during the construction of weak current engineering, the hard disk in the computer is easily damaged by vibration during transportation, resulting in the loss of weak current data due to the vibration damage of the hard disk. Therefore, we have proposed a computer protection device for weak current engineering. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a computer protection device for weak current engineering, which solves the problems raised in the above background art.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A computer protection device for a weak current project, including a chassis. On the top left side of the inner wall of the chassis, a power supply is fixedly installed. On the left side of the front of the inner wall of the chassis, a motherboard is fixedly installed. At the bottom of the left and right sides of the inner wall of the chassis, U-shaped frames are fixedly installed. At the bottom end inside the U-shaped frames, six horizontal partitions are fixed. At the bottom end inside the U-shaped frames, three hard disks are fixedly installed. The three hard disks are located between the six horizontal partitions. At the back of each of the three hard disks, a cable is fixedly installed. One end of each of the three cables away from the three hard disks is fixedly connected to the bottom of the front of the motherboard. A vibration-proof component is arranged at the bottom end inside the U-shaped frames; The vibration-proof component includes two micro electric telescopic rods. The two micro electric telescopic rods respectively penetrate and are fixed at the bottom end inside the U-shaped frames. The two micro electric telescopic rods are located on the left and right sides of the inner wall of the U-shaped frames. The bottom surfaces of the two micro electric telescopic rods are fixedly connected to the bottom end inside the chassis. On the top surfaces of the telescopic ends of the two micro electric telescopic rods, a horizontal plate is fixed. On the bottom surface of the horizontal plate, three square shells are fixed. At the top ends inside each of the three square shells, two elastic pieces are fixed. Inside the inner walls of the three square shells, rubber blocks are slidably installed. The top surfaces of the three rubber blocks are fixedly connected to the bottom surfaces of each elastic piece. Under the elastic force of the elastic pieces, the rubber blocks tightly press against the upper sides of the hard disks, preventing the hard disks in the chassis from being damaged by vibration. A non-slip component is arranged on the top surfaces of the three square shells; The non-slip component includes three sliding shells. The three sliding shells are fixedly installed on the top surfaces of the three square shells. The three sliding shells are located in front of the horizontal plate. Inside the fronts of the three square shells, a number of first springs are fixed. Inside the inner walls of the three square shells, L-shaped sliding plates are slidably installed. One end of each of the number of first springs away from the square shells is fixedly connected to the backs of the three L-shaped sliding plates. The L-shaped sliding plates limit the hard disks in the horizontal partitions, preventing the hard disks from sliding forward in the U-shaped frames during severe shaking; In the middle of the top surfaces of the three sliding shells, an opening device is arranged. On the mutually remote sides of the opening device, a limiting device is arranged.

[0007] According to the above technical solutions, three heat dissipation strip openings are provided on the left side of the chassis. Two heat dissipation strip openings are provided on the left side of the U-shaped frames. The two heat dissipation strip openings of the U-shaped frames are aligned with the two heat dissipation strip openings at the lower left side of the chassis. The three rubber blocks are all located above the three hard disks. The fronts of the three hard disks are all on the movement tracks of the three L-shaped sliding plates.

[0008] According to the above technical solution, the box opening device includes three short columns, a rectangular shell, two elastic filter meshes, and two long plates. The three short columns are fixed in the middle of the top surfaces of the three sliding shells. The rectangular shell is fixed on the top surfaces of the three short columns. Two chutes are provided on the top surface of the rectangular shell. A dehumidifying agent is arranged in the middle of the rectangular shell. The two elastic filter meshes are fixed on the front and back of the rectangular shell. The two long plates are slidably installed on the inner walls of the two chutes of the rectangular shell. The two ends of the two long plates are fixedly connected to the left and right sides of the inner wall of the chassis. The chute of the rectangular shell moves downward on the long plate, and the rectangular shell ventilates through the elastic filter mesh, enabling the dehumidifying agent in the rectangular shell to dehumidify the inside of the chassis.

[0009] According to the above technical solution, the box opening device further includes two double-ring plates, two T-shaped plates, two sliding columns, and two grooved rollers. The two double-ring plates are fixed on the outer walls of the two long plates. The two double-ring plates are located on the left and right sides of the rectangular shell. The two T-shaped plates are fixed in the middle of the bottom surfaces of the two double-ring plates. A sliding opening is provided on each of the two sides of the two T-shaped plates that are away from each other. The two sliding columns are slidably installed on the inner walls of the sliding openings of the two T-shaped plates. The two sides of the two sliding columns that are close to each other are fixedly connected to the left and right sides of the rectangular shell. The two grooved rollers are respectively rotatably installed at the bottoms of the two sides of the two T-shaped plates that are close to each other. The two grooved rollers are located on the front and back of the rectangular shell. During the rotation of the grooved rollers, the grooves of the grooved rollers will strike the elastic filter mesh, causing the elastic filter mesh to vibrate, so that foreign objects will not block the mesh gaps of the elastic filter mesh.

[0010] According to the above technical solution, the two long plates are respectively located on the sides of the two elastic filter meshes that are close to each other. A number of grooves are provided on the outer walls of the two grooved rollers. The sides of the two elastic filter meshes that are away from each other are both in the movement tracks of the two grooved rollers.

[0011] According to the above technical solution, the limiting device includes two L-shaped rods, two bottom-sealing grooves, and two square blocks. The two L-shaped rods are respectively fixed on the sides of the two sliding columns that are away from each other. The two bottom-sealing grooves are respectively fixed on the left and right sides of the inner wall of the chassis. The two square blocks are respectively fixed on the top surfaces of the two L-shaped rods. The outer walls of the two square blocks are slidably connected to the inner walls of the two bottom-sealing grooves. During the downward movement of the square blocks, the bottom-sealing grooves limit the square blocks, so that the rubber blocks in the device will not excessively squeeze the hard disk.

[0012] According to the above technical solution, the limiting device further includes two short cylinders, two second springs, two round-headed columns and two L-shaped short plates. The two short cylinders are respectively fixed on one side of the two square blocks close to each other. The two second springs are respectively fixed on the inner walls of the two short cylinders. The two round-headed columns are slidably installed on the inner walls of the two short cylinders. One side of the two round-headed columns away from each other is fixedly connected to one end of the two second springs away from the two short cylinders. The two L-shaped short plates are respectively fixed on the tops of one side of the two T-shaped plates away from each other. Under the elastic force of the second spring, the round-headed column abuts against the L-shaped short plate, so that during the handling of the rectangular shell, the rectangular shell will not vibrate and become loose.

[0013] According to the above technical solution, the bottom ends of the two bottom sealing grooves are respectively on the movement tracks of the two square blocks, and the two L-shaped short plates are respectively on the movement tracks of the two round-headed columns.

[0014] The present invention provides a computer protection device for weak current engineering. It has the following beneficial effects: (1) Through the cooperation of the U-shaped frame, the transverse partition, the hard disk, the wiring harness, the micro electric telescopic rod, the transverse plate, the square shell, the elastic sheet, the rubber block, the sliding shell and the first spring with the L-shaped sliding plate, under the elastic force of the elastic sheet, the rubber block tightly abuts above the hard disk, so that the hard disk in the computer case will not be damaged by vibration, preventing the loss of weak current data caused by the vibration damage of the hard disk in the computer. And the L-shaped sliding plate restricts the hard disk in the transverse partition, so that the hard disk will not slide forward in the U-shaped frame during severe jolting, preventing the hard disk from hitting the computer case when sliding forward during severe jolting.

[0015] (2) Through the setting of the box opening device, the short column, the rectangular shell, the elastic filter screen, the long plate, the double-ring plate, the T-shaped plate and the sliding column cooperate with the fine groove roller. The sliding groove of the rectangular shell moves downward on the long plate, and the rectangular shell ventilates through the elastic filter screen, so that the dehumidifying agent in the rectangular shell dehumidifies the inside of the computer case, preventing the electronic components in the computer from being affected by moisture due to the harsh construction site environment. And during the rotation of the fine groove roller, the groove of the fine groove roller will knock on the elastic filter screen, and the elastic filter screen will vibrate, so that the mesh gaps of the elastic filter screen will not be blocked by foreign objects, preventing the poor dehumidification effect of the device caused by the blockage of the mesh gaps of the elastic filter screen.

[0016] (3) Through the setting of the limiting device, the L-shaped rod, the bottom sealing groove, the square block, the short cylinder, the second spring and the round-headed column cooperate with the L-shaped short plate. During the downward movement of the square block, the bottom sealing groove limits the square block, so that the rubber block in the device will not excessively squeeze the hard disk, preventing the hard disk in the computer case from being damaged due to the excessive squeezing of the rubber block. And under the elastic force of the second spring, the round-headed column abuts against the L-shaped short plate, so that during the handling of the rectangular shell, the rectangular shell will not vibrate and become loose, preventing the rectangular shell in the computer case from loosening and causing the rectangular shell to displace and hit the electronic components.

DETAILED DESCRIPTION OF THE INVENTION

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Please refer to Figures 1-8, an embodiment of the present invention is: a computer protection device for a weak current project, including a chassis 1. On the top left side of the inner wall of the chassis 1, a power supply 2 is fixedly installed. On the left side of the front inner wall of the chassis 1, a main board 3 is fixedly installed. At the bottom of the left and right sides of the inner wall of the chassis 1, a U-shaped frame 4 is fixedly installed. At the bottom end inside the U-shaped frame 4, six cross partitions 7 are fixed. At the bottom end inside the U-shaped frame 4, three hard disks 8 are fixedly installed. The three hard disks 8 are located between the six cross partitions 7. On the back of each of the three hard disks 8, a cable 9 is fixedly installed. One end of each of the three cables 9 away from the three hard disks 8 is fixedly connected to the bottom of the front of the main board 3. Three heat dissipation slots are opened on the left side of the chassis 1. Two heat dissipation slots are opened on the left side of the U-shaped frame 4. The two heat dissipation slots of the U-shaped frame 4 are aligned with the two heat dissipation slots at the lower left side of the chassis 1; A vibration-proof component 41 is arranged at the bottom end inside the U-shaped frame 4. The vibration-proof component 41 includes two micro electric telescopic rods 411. The two micro electric telescopic rods 411 respectively penetrate and are fixed at the bottom end inside the U-shaped frame 4. The two micro electric telescopic rods 411 are located on the left and right sides of the inner wall of the U-shaped frame 4. The bottom surfaces of the two micro electric telescopic rods 411 are fixedly connected to the bottom end inside the chassis 1. On the top surfaces of the telescopic ends of the two micro electric telescopic rods 411, a cross plate 412 is fixed. On the bottom surface of the cross plate 412, three square shells 413 are fixed. At the top ends inside each of the three square shells 413, two elastic pieces 414 are fixed. Inside the inner walls of the three square shells 413, rubber blocks 415 are slidably installed. The top surfaces of the three rubber blocks 415 are fixedly connected to the bottom surfaces of each elastic piece 414. The three rubber blocks 415 are all located above the three hard disks 8. Under the elastic force of the elastic pieces 414, the rubber blocks 415 tightly press against the upper sides of the hard disks 8, so that when the computer for the weak current project is carried, the hard disks 8 in the chassis 1 will not be damaged by vibration, and it is avoided that when the computer for the weak current project is carried at the construction site, the hard disks 8 in the computer vibrate and are damaged, resulting in the loss of weak current data; An anti-slip component 42 is arranged on the top surfaces of the three square shells 413. The anti-slip component 42 includes three sliding shells 421. The three sliding shells 421 are fixedly installed on the top surfaces of the three square shells 413. The three sliding shells 421 are located in front of the cross plate 412. A number of first springs 422 are fixed to the front inside of the three square shells 413. Inside the inner walls of the three square shells 413, L-shaped sliding plates 423 are slidably installed. One end of each of the number of first springs 422 away from the square shells 413 is fixedly connected to the back surfaces of the three L-shaped sliding plates 423. The fronts of the three hard disks 8 are all on the movement tracks of the three L-shaped sliding plates 423. The L-shaped sliding plates 423 limit the hard disks 8 in the cross partitions 7, so that when the hard disks 8 are violently shaken, they will not slide forward in the U-shaped frame 4, and it is avoided that when the computer for the weak current project is carried at the construction site, the hard disks 8 slide forward during the violent shaking process and collide with the chassis 1.

[0021] During use, the chassis 1 supports the power supply 2 and the motherboard 3. Since the computer needs to be carried to the designated construction site during the construction of the weak current project, the hard disk 8 in the computer is easily damaged by vibration during the handling process. At this time, the chassis 1 supports the U-shaped frame 4, the U-shaped frame 4 supports the transverse partition 7, the U-shaped frame 4 supports the hard disk 8, and the transverse partition 7 limits the hard disk 8 left and right. At the same time, the hard disk 8 supports the cable 9. When the computer for the weak current project needs to be carried, the micro electric telescopic rod 411 on the U-shaped frame 4 is started, and the telescopic end of the micro electric telescopic rod 411 begins to move downward. The telescopic end of the micro electric telescopic rod 411 drives the cross plate 412 to move downward, the cross plate 412 drives the square shell 413 to move downward, the square shell 413 drives the elastic piece 414 to move downward, and the elastic piece 414 drives the rubber block 415 to move downward. During the downward movement of the rubber block 415, the rubber block 415 contacts the hard disk 8. Under the action of the extrusion force, the rubber block 415 slides upward in the square shell 413. The rubber block 415 drives the elastic piece 414 to move upward, and the elastic piece 414 begins to deform. Under the elastic force of the elastic piece 414, the rubber block 415 tightly abuts above the hard disk 8, so that the hard disk 8 in the chassis 1 of the computer for the weak current project will not be damaged by vibration during handling, preventing the hard disk 8 in the chassis 1 from being damaged by vibration during equipment handling, thereby avoiding the problem of weak current data loss caused by the vibration and damage of the hard disk 8 in the computer for the weak current project during construction site handling.

[0022] While the cross plate 412 drives the square shell 413 to move downward, the square shell 413 drives the sliding shell 421 to move downward, the sliding shell 421 drives the first spring 422 to move downward, and the first spring 422 drives the L-shaped sliding plate 423 to move downward. During the downward movement of the L-shaped sliding plate 423, the L-shaped sliding plate 423 contacts the hard disk 8. Under the action of the extrusion force, the L-shaped sliding plate 423 slides downward in front of the hard disk 8, so that the L-shaped sliding plate 423 restricts the hard disk 8 in the transverse partition 7, so that the hard disk 8 will not slide forward in the U-shaped frame 4 during severe shaking, preventing the hard disk 8 in the chassis 1 from sliding forward during equipment handling, thereby avoiding the problem that the hard disk 8 collides with the chassis 1 during severe shaking of the hard disk 8 during the construction site handling of the computer for the weak current project.

[0023] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, an opening device 5 is provided in the middle of the top surfaces of the three sliding shells 421. The opening device 5 includes three short columns 51, a rectangular shell 52, two elastic filter meshes 53, and two long plates 54. The three short columns 51 are fixed in the middle of the top surfaces of the three sliding shells 421, and the rectangular shell 52 is fixed on the top surfaces of the three short columns 51. Two chutes are provided on the top surface of the rectangular shell 52. A dehumidifying agent is provided in the middle of the rectangular shell 52. The two elastic filter meshes 53 are fixed on the front and back of the rectangular shell 52. The two long plates 54 are slidably installed on the inner walls of the two chutes of the rectangular shell 52. The two ends of the two long plates 54 are fixedly connected to the left and right sides of the inner wall of the chassis 1. The two long plates 54 are respectively located on one side where the two elastic filter meshes 53 are close to each other. A plurality of grooves are provided on the outer walls of the two fine groove rollers 58. The chute of the rectangular shell 52 moves downward on the long plate 54. The rectangular shell 52 ventilates through the elastic filter mesh 53, enabling the dehumidifying agent in the rectangular shell 52 to dehumidify the inside of the chassis 1, and preventing the electronic components in the computer for weak current engineering from getting damp when the computer is carried at the construction site where the environment is harsh.

[0024] The opening device 5 further includes two double-ring plates 55, two T-shaped plates 56, two sliding columns 57, and two fine groove rollers 58. The two double-ring plates 55 are fixed on the outer walls of the two long plates 54. The two double-ring plates 55 are located on the left and right sides of the rectangular shell 52. The two T-shaped plates 56 are fixed in the middle of the bottom surfaces of the two double-ring plates 55. Slide openings are provided on one side of the two T-shaped plates 56 away from each other. The two sliding columns 57 are slidably installed on the inner walls of the slide openings of the two T-shaped plates 56. The two sliding columns 57 are fixedly connected to the left and right sides of the rectangular shell 52 on one side close to each other. The two fine groove rollers 58 are respectively rotatably installed at the bottom of one side of the two T-shaped plates 56 close to each other. The two fine groove rollers 58 are located on the front and back of the rectangular shell 52. One side of the two elastic filter meshes 53 away from each other is in the movement track of the two fine groove rollers 58. During the rotation of the fine groove rollers 58, the grooves of the fine groove rollers 58 will knock on the elastic filter meshes 53, and the elastic filter meshes 53 will vibrate, preventing foreign objects from blocking the mesh gaps of the elastic filter meshes 53, and preventing the poor dehumidification effect of the equipment caused by the blockage of the mesh gaps of the elastic filter meshes 53 when the computer for weak current engineering is carried at the construction site.

[0025] On one side of the box-opening device 5 that are far away from each other, there is a limiting device 6. The limiting device 6 includes two L-shaped rods 61, two bottom-sealing grooves 62, and two square blocks 63. The two L-shaped rods 61 are respectively fixed on the sides of the two sliding columns 57 that are far away from each other. The two bottom-sealing grooves 62 are respectively fixed on the left and right sides of the inner wall of the chassis 1. The two square blocks 63 are respectively fixed on the top surfaces of the two L-shaped rods 61. The outer walls of the two square blocks 63 are slidably connected to the inner walls of the two bottom-sealing grooves 62. The bottoms of the two bottom-sealing grooves 62 are respectively on the movement trajectories of the two square blocks 63. During the downward movement of the square block 63, the bottom-sealing groove 62 limits the square block 63, so that the rubber block 415 in the device does not overly squeeze the hard disk 8, avoiding damage to the hard disk 8 in the chassis 1 caused by the rubber block 415 overly squeezing the hard disk 8 when the computer for weak current engineering is carried at the construction site.

[0026] The limiting device 6 further includes two short cylinders 64, two second springs 65, two round-headed columns 66, and two L-shaped short plates 67. The two short cylinders 64 are respectively fixed on the sides of the two square blocks 63 that are close to each other. The two second springs 65 are respectively fixed on the inner walls of the two short cylinders 64. The two round-headed columns 66 are slidably installed on the inner walls of the two short cylinders 64. The sides of the two round-headed columns 66 that are far away from each other are fixedly connected to the ends of the two second springs 65 that are far away from the two short cylinders 64. The two L-shaped short plates 67 are respectively fixed on the tops of the sides of the two T-shaped plates 56 that are far away from each other. The two L-shaped short plates 67 are respectively on the movement trajectories of the two round-headed columns 66. Under the elastic force of the second spring 65, the round-headed column 66 abuts against the L-shaped short plate 67, so that during the handling process of the rectangular shell 52, the rectangular shell 52 does not vibrate and become loose, avoiding displacement and collision of the rectangular shell 52 in the chassis 1 with electronic components when the computer for weak current engineering is carried at the construction site.

[0027] While the square shell 413 drives the sliding shell 421 to move downward, the sliding shell 421 drives the short column 51 to move downward, the short column 51 drives the rectangular shell 52 to move downward, and the rectangular shell 52 drives the elastic filter screen 53 to move downward. At the same time, the sliding groove of the rectangular shell 52 moves downward on the long plate 54, so that the rectangular shell 52 ventilates through the elastic filter screen 53, allowing the desiccant in the rectangular shell 52 to dehumidify the inside of the chassis 1, preventing the inside of the chassis 1 from getting damp due to the harsh construction site environment during transportation, thereby avoiding the problem that the electronic components in the computer get damp due to the harsh construction site environment when the computer for weak current engineering is carried at the construction site.

[0028] While the short column 51 drives the rectangular shell 52 to move downward, the long plate 54 supports the double-ring plate 55, the double-ring plate 55 supports the T-shaped plate 56, the rectangular shell 52 drives the sliding column 57 to move downward, and the sliding column 57 slides downward in the slot of the T-shaped plate 56. At the same time, during the process that the rectangular shell 52 drives the elastic filter screen 53 to move downward, the elastic filter screen 53 contacts the fine groove roller 58. Under the action of friction, the fine groove roller 58 rotates on the T-shaped plate 56, so that during the rotation of the fine groove roller 58, the grooves of the fine groove roller 58 will knock on the elastic filter screen 53, and the elastic filter screen 53 will vibrate, preventing foreign objects from blocking the mesh seams of the elastic filter screen 53, and avoiding the problem that the mesh seams of the elastic filter screen 53 are blocked during the transportation of the equipment, thus preventing the problem that the dehumidification effect of the computer for weak current engineering is poor due to the blockage of the mesh seams of the elastic filter screen 53 when the equipment is carried at the construction site.

[0029] While the rectangular shell 52 drives the sliding column 57 to move downward, the sliding column 57 drives the L-shaped rod 61 to move downward, the L-shaped rod 61 drives the square block 63 to move downward, and the square block 63 slides downward in the bottom sealing groove 62. So that during the downward movement of the square block 63, the bottom sealing groove 62 limits the square block 63, preventing the rubber block 415 in the equipment from excessively squeezing the hard disk 8, and avoiding the problem that the hard disk 8 in the chassis 1 is damaged due to the excessive squeezing of the rubber block 415 when the equipment is carried, thus preventing the problem that the hard disk 8 in the computer for weak current engineering is damaged due to the excessive squeezing of the rubber block 415 when the equipment is carried at the construction site.

[0030] While the L-shaped rod 61 drives the square block 63 to move downward, the square block 63 drives the short cylinder 64 to move downward, the short cylinder 64 drives the second spring 65 to move downward, and the second spring 65 drives the round head column 66 to move downward. During the downward movement of the round head column 66, the round head column 66 contacts the L-shaped short plate 67. Under the action of the extrusion force, the round head column 66 slides in the short cylinder 64, and the second spring 65 on the round head column 66 starts to contract. Under the elastic force of the second spring 65, the round head column 66 abuts against the L-shaped short plate 67, preventing the rectangular shell 52 from vibrating and loosening during transportation, and avoiding the problem that the rectangular shell 52 in the chassis 1 loosens when the equipment is carried, thus preventing the problem that the rectangular shell 52 in the computer for weak current engineering displaces and knocks against electronic components when the equipment is carried at the construction site.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
