Description

Technical Field

[0001] The present invention relates to the technical field of computer maintenance equipment, and in particular to computer maintenance auxiliary equipment. Background Art

[0002] In addition to common notebooks and desktop computers, computers also include many special-purpose models. These computers have complex internal components and compact layouts. When repairing them, it is often difficult to directly touch and operate them with your hands. A very simple example is the power cord that connects the corresponding modules inside the computer, which is usually some flat cables. It is very difficult to insert the power cable terminals into the ports of the corresponding computer function modules because it is inconvenient to move your hands inside the computer, and your hands and arms can easily block your sight, making repair difficult.

[0003] In addition, during the computer maintenance process, once the corresponding electronic components are held in the hand and enter the computer, it is easy for the hand to touch the internal electronic components, causing scratches on the hand, or the electronic components to be damaged or loose, causing the originally faulty computer to accidentally add a new fault that cannot be detected in time, thereby increasing the difficulty of maintenance. Moreover, directly touching the electronic components with hands and the sweat on the hands are also harmful to the electronic components.

[0004] During computer maintenance, an essential operation is to clean the corresponding electronic components to remove dust, or blow away the moisture on the surface, so as to promptly eliminate faults caused by poor contact of electronic components. Therefore, when repairing a computer, it is also necessary to unplug the corresponding cable terminals and other electronic components, then purge the corresponding interfaces or ports, and then reinsert the electronic components to determine whether there is poor contact. These operations will cause hands to frequently enter the computer, increase the probability of touching the internal electronic components, prolong the maintenance time, and even trigger secondary faults with a high probability, making maintenance more difficult, especially for industrial computers with extremely high functional integration, which have many internal modules, more complex layouts, and more inconvenient maintenance operations.

[0005] The computer maintenance scenarios mentioned above are only a few common ones. In actual maintenance, whether it is a common desktop host or a special-purpose industrial computer, there are many other similar problems, which not only cause inconvenience in maintenance, but also increase the difficulty of successful maintenance.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. 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.

[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0039] See also Figure 1The present invention provides a technical solution: a computer maintenance auxiliary device, mainly comprising two clamping blocks 1 arranged opposite to each other in the upper and lower parts, the clamping blocks 1 can be a rectangular strip-shaped structure, and the two clamping blocks 1 are connected by a support spring 5, and the support spring 5 can make the two clamping blocks 1 maintain an initial spacing distance, that is, a gap between each other, so that some computer components can be placed at the initial moment, such as the cable plug end of the power cord, that is, flatly placed into a cable terminal 13. At the same time, the two clamping blocks 1 in this embodiment are also provided with a magnetic component, and the magnetic component includes at least one electromagnet 2 installed in one of the clamping blocks 1. During operation, once the electromagnet 2 is energized, the two clamping blocks 1 move closer to each other, so that Figure 2 As shown, components such as the cable terminal 13 of the computer are clamped between the two so that they can be moved to the corresponding position for plugging during maintenance. In addition, in this embodiment, it is also necessary to provide an air jet hole 14 in at least one clamp block 1, and the air jet hole 14 is connected to a compressed air source. With such a design, the air jet hole 14 can blow clean air toward the corresponding components inside the computer. For example, when repairing the plug-in ports of some cables, the clamp block 1 can be moved to the plug-in port first and then blown to remove dust in the plug-in port, or other pollutants or water stains that may be contaminated inside due to maintenance can be blown dry. In this way, during maintenance, the plug-in can be plugged in after blowing. That is, if the fault still occurs after the cable terminal 13 is pulled out, it is sufficient to first eliminate the poor contact caused by dust accumulation in the plug-in port, which can facilitate maintenance personnel to quickly diagnose and eliminate the cause of the fault as soon as possible.

[0040] In this embodiment, Figure 1 At the same end of the two clamping blocks 1, there are also provided a plug-in pipe 4 and a spigot pipe 3 which are coaxially butted and slidably matched with each other. The plug-in pipe 4 and the spigot pipe 3 can be integrally formed with the corresponding clamping block 1. Specifically, the spigot pipe 3 is arranged on one side of the bottom surface of the upper clamping block 1, and the bottom end of the plug-in pipe 4 is fixedly arranged on one side of the top surface of the lower clamping block 1, for example Figure 1 As shown, the top of the plug-in tube 4 is inserted into the spigot 3 on the upper or lower surface on the right side, respectively, and the axial sliding fit is provided, and a guide column 6 is vertically fixed to one side of the top surface of the lower clamping block 1, and the guide column 6 passes through the upper clamping block 1 in an axial sliding fit, and the cross section of the guide column 6 is rectangular, so as to prevent the two clamping blocks 1 from rotating relative to each other, and only limit the relative vertical movement to each other. In practice, a support spring 5 is coaxially provided in the plug-in tube 4, and the support spring 5 is located outside the guide column 6, that is, it is sleeved on the guide column 6, preferably without contact, and the top of the support spring 5 is connected to the bottom of the spigot 3 to bear pressure well.

[0041] In this embodiment, Figure 1, the guide column 6 is coaxially connected to a telescopic rod 7, the top end of the telescopic rod 7 is hinged on a mounting frame 9, and the bottom end is a telescopic end and is coaxially fixed to the guide column 6, that is, after the telescopic rod 7 and the guide column 6 are connected, the two form a telescopic connecting arm. In addition, a driving component is fixedly mounted on the mounting frame 9, and the driving component is transmission-connected with the hinge shaft 8 of the telescopic rod 7 on the mounting frame 9, and drives the hinge shaft 8 to rotate, so that the hinge shaft 8 and the telescopic rod 7 fixed on the hinge can be driven to rotate, thereby driving the clamping assembly formed by the two clamping blocks 1 to rotate, so that when repairing the computer, the above-mentioned clamping assembly can be turned to the position such as Figure 2 The position shown in FIG. 1 is used to insert corresponding cables and other components into the plug-in port on the front inner wall of the computer case, and when the computer case is rotated 90 degrees to the rear, the computer case is positioned as shown in FIG. Figure 5 At the position shown, the corresponding cable and other components can be inserted into the plug-in port on the bottom inner wall of the computer case. Similarly, it can be rotated at other angles to plug cables into the plug-in ports on different inner walls or clean the corresponding ports, etc. In specific use, the above-mentioned guide pillars 6 and clamping blocks 1 can be made smaller, so that a smaller space can be entered to perform the above-mentioned maintenance work, avoiding the inconvenience of human hands directly reaching into the corresponding position and avoiding the risk of scratches when moving hands inside the computer.

[0042] In the above embodiments, in more detail, Figure 1 As shown, the mounting frame 9 can be made into a [-shaped channel steel structure with an opening facing downward, and the two ends of the hinge shaft 8 are respectively rotatably mounted in the two opposite side walls of the groove of the mounting frame 9 to realize the rotatable installation of the telescopic rod 7 and the guide column 6. In addition, the driving component includes a micro motor 10, a driving gear 11, and a driven gear 12. The micro motor 10 used is fixed on the back of the groove of the mounting frame 9, and the driving gear 11 is fixed on the main shaft of the micro motor 10. The driving gear 11 is meshed and connected with the driven gear 12. The driven gear 12 is fixed to the end of the hinge shaft 8 extending out of the mounting frame 9. When the micro motor 10 rotates a corresponding angle, the clamping block 1 can be rotated by a corresponding angle through gear transmission to change the working position.

[0043] Based on the above design, this embodiment further includes an air compressor (not shown in the figure) and a controller (not shown in the figure). The telescopic rod 7 is a pneumatic telescopic rod 7. The pneumatic telescopic rod 7 and the air jet hole 14 share a compressed air source output by the air compressor. The controller can control the compressed air source through a regulating valve to selectively supply air to the pneumatic telescopic rod 7 and the air jet hole 14, so as to realize the extension or contraction of the telescopic rod 7 alone, or realize the air jet cleaning operation alone, or when air is supplied at the same time, it can be extended or contracted while performing large-area cleaning maintenance.

[0044] In this embodiment, the outlet end of the main air pipe output by the air compressor used above is connected to a regulating valve. Figure 6-7 As shown, the regulating valve includes a main body 19 and a valve column 20. The valve column 20 is installed inside the main body 19. The valve column 20 is cylindrical. The valve cavity 1901 of the main body 19 for the valve column 20 to be axially movable is also cylindrical. There are a plurality of air outlet holes on the inner wall of the valve cavity 1901. The arrangement of these air outlet holes is as follows: Figure 6-Figure 8 ,as well as Figure 10-12 As shown, a first air outlet 2401 is provided on the front side of the upper side wall of the valve chamber 1901 to connect the cylinder of the pneumatic telescopic rod 7 to drive the telescopic rod 7; a second air outlet 2402 is provided on the rear side of the middle side wall of the valve chamber 1901 to connect the jet hole 14 to clean the corresponding part inside the computer; a third air outlet 2403 is provided on each of the front and rear sides of the lower side wall of the valve chamber 1901 to connect the cylinder and the jet hole 14 respectively. , so as to move the telescopic rod 7 and clean the inside of the computer at the same time, and a one-way valve is installed on the air supply pipeline 26 connected to each air outlet 24, and the one-way valve can only allow compressed air to flow out from the air outlet 24, so that when the valve column 20 moves vertically in the valve cavity 1901, when the valve column 20 moves downward, the air supply channel 29 on the valve column 20 can be connected with the first air outlet 2401, the second air outlet 2402 and the third air outlet 2403 in sequence. In the above structural design, the purpose of using the one-way valve is to avoid the compressed air from flowing back into the valve cavity 1901 due to the cross-flow between the similar pipelines connecting the telescopic rod 7 or the air injection hole 14. In specific implementation, this one-way valve is preferably installed on the air outlet 24.

[0045] In this embodiment, Figure 6-Figure 7 as well as Fig. 9 As shown, a section of sleeve 21 is coaxially fixed to the bottom end of the valve column 20, and a high-pressure pipe 22 for conveying compressed air is rotatably and sealedly inserted in this section of sleeve 21. The high-pressure pipe 22 is preferably a section of rigid pipe, such as a stainless steel pipe. One end of the high-pressure pipe 22 located in the sleeve 21 is connected to the air supply channel 29 in the valve column 20, and the outlet end of the air supply channel 29 is located at the bottom of an annular groove 28 at the bottom end of the valve column 20. The annular groove 28 is used to connect with the air outlet 24 to convey compressed air, so that the compressed air input through the stainless steel pipe enters the sleeve 21, and then enters the air supply channel 29, and then flows into the annular groove 28, and finally outputs to the corresponding telescopic rod 7 or the jet hole 14 through the air outlet 24 directly opposite to the annular groove 28. The high-pressure pipe 22 is rotationally and sealingly inserted into the sleeve 21 in the above design so that the sleeve 21 and the high-pressure pipe 22 can be sealed and connected without leakage when the valve column 20 rotates or moves axially.

[0046] In this embodiment, based on the matching structure of the main body 19 and the valve column 20, the structural design of the vertical movement of the valve column 20 in the valve cavity 1901 can be one of the following two transmission structures: as a transmission structure 1, such as Figure 6-Figure 7 Specifically, a stud 23 is coaxially fixed to the top of the valve column 20. After the stud 23 is threadedly fitted through the closed end at the top of the main body 19, a turntable 25 is fixed. The valve column 20 is axially slidably connected to the valve cavity 1901. Then, by rotating the turntable 25, the valve column 20 can be axially moved in the valve cavity 1901, thereby connecting the annular groove 28 with the corresponding air outlet 24. As for where the connection can be seen, it can be adaptively designed. For example, scale marks (not shown in the figure) are set on the stud 23. When the three scale marks are located in sequence on the top surface of the main body 19, they correspond to three height positions of the valve column 20 in the valve cavity 1901, thereby corresponding to three ventilation states.

[0047] As the design of the second transmission structure, Figure 8-Figure 9 The top of the main body 19 is open, so that the valve cavity 1901 is a threaded blind hole structure with the opening facing upward, and the cylindrical surface of the valve column 20 has threads, and the threads here are all pipe threads, which are self-sealing. The threaded connection can achieve sealing, so that the valve column 20 and the valve cavity 1901 are installed in a threaded matching manner, and a turntable 25 is fixed to the top of the valve column 20 through a connecting column. Rotating the turntable 25 can drive the valve column 20 to move axially in the form of a threaded pair, and then correspond to three ventilation states. In this design, the space between the annular groove 28 and the corresponding air outlet 24 in the valve cavity 1901 is avoided from being mixed with the air outlet 24 at other heights, relying on the self-sealing of the pipe thread. It is recommended for use in occasions where the compressed air pressure is not high. If the compressed air pressure is high, it is recommended to adopt the aforementioned first transmission structure design.

[0048] In this embodiment, Figure 3-Figure 4 Each clamp block 1 is provided with an inlet flow channel horizontally, and an inlet connector 15 is installed at one end of the inlet flow channel. The inlet interface is connected to a compressed air source, for example, to a certain outlet hole 24 mentioned above, and the other end of the inlet flow channel is closed. Several rows of jet holes 14 are arranged at intervals on both sides of the inlet flow channel, and all the jet holes 14 are connected to the inlet flow channel, so that each jet hole 14 can simultaneously spray compressed air for wide-area cleaning. When repairing a computer, sometimes only one side needs to be used for jet cleaning in a targeted manner, so it can be done as follows Figure 4As shown, a shielding plate 17 is installed on one side of each clamping block 1, and one end of the shielding plate 17 is connected to a T-shaped guide bolt 18 and a T-shaped guide bolt arranged on the surface of the clamping block 1. After the T-shaped bolt 18 is loosened, the shielding plate 17 can be translated to a position where the row of air injection holes 14 corresponding to it are completely covered or completely exposed, and then fixed to the clamping block 1 as a whole. When all are covered, the single side of the clamping block 1 can be sprayed, and when all are exposed, the double sides can be cleaned in a large range. In order to protect the internal components of the clamped computer, such as Figure 3 As shown, a rubber sheet 16 can be fixed on the surface of the opposite side of the two clamping blocks 1, and the rubber sheet 16 here is used for pressing and contacting with the cable terminal 13 of the computer to avoid crushing the internal components of the computer such as the cable terminal 13.

[0049] Finally, as a specific implementation structure, such as Figure 2 The magnetic assembly mentioned above includes two electromagnets 2, and the two electromagnets 2 are arranged to attract each other, so that after the two electromagnets 2 are powered on, the two clamps 1 can be moved close to each other by magnetic attraction, that is, after the two clamps 1 are moved to the point where the terminals of the power cable are located between them, the electromagnets 2 are powered on, the terminals of the power cable are clamped, and then it is easy to plug them into the corresponding port. As for the arrangement of the power on and off control structure of the electromagnet 2, the power button can be set on the above-mentioned controller or other convenient locations for operation. This embodiment does not make specific restrictions, nor is it a creative design point of the present invention. Those skilled in the art can make adaptive choices.
