Description

Technical Field

[0001] This invention relates to the field of computer data acquisition device technology, specifically a portable computer data acquisition device. Background Technology

[0002] A computer data acquisition device is a device used to convert external physical quantities (such as temperature, pressure, voltage, etc.) into digital signals that can be processed by a computer. It is widely used in scientific research, industrial automation, environmental monitoring, medical diagnosis, and other fields.

[0003] Patent announcement number CN207946813U discloses a computer data acquisition device based on the Internet of Things, comprising an acquisition device body, an LED display screen on the upper front of the acquisition device body, a scanner below the LED display screen, a manual input button below the scanner, a memory card slot and a USB slot on the left side of the acquisition device body, an antenna hole on the left side of the top surface of the acquisition device body, an antenna installed in the antenna hole, and a telescopic rod fixedly connected to the bottom of the acquisition device body, the bottom end of the telescopic rod being fixed to a base.

[0004] However, when the aforementioned computer data acquisition device is used for environmental data collection and testing outdoors, it is prone to collapse and damage when placed on uneven ground such as in parks. This is because such ground is often uneven and bumpy, which can lead to the device collapsing and being damaged in windy or other adverse weather conditions, thus affecting the test results. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a portable computer data acquisition device that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable computer data acquisition device, comprising a data acquisition unit, a button fixed on the front of the data acquisition unit, an antenna fixed on the top of the data acquisition unit, a detachable fixing column installed on the bottom of the data acquisition unit, a support plate fixed on the bottom of the fixing column, a support device for improving device stability provided inside the fixing column, a protective device for preventing device collapse provided on the outer wall of the fixing column, and an auxiliary device provided on the support plate.

[0007] Specifically, the support device includes an electric push rod, an output rod, a stabilizing column, a rotating column, a plug, a corrugated plate, a transmission block, a protrusion, a pressing block, and a transmission spring. The electric push rod is fixed to the inner wall of the fixed column, the output rod is fixed to the bottom output end of the electric push rod, the stabilizing column is fixed to the bottom of the output rod, the rotating column is rotatably installed on the inner wall of the stabilizing column, and the plug is fixed to the bottom of the rotating column. When the device is used outdoors, the support plate is placed on a muddy surface such as in a park. By activating the electric push rod, the output rod can be moved downwards, thereby driving the stabilizing column and the plug to be inserted into the mud.

[0008] According to the above technical solution, the wave plate is fixed to the inner wall of the fixed column, the transmission block passes through the stabilizing column and is slidably connected at the penetration point, and the protrusion is fixed to the top of the rotating column.

[0009] According to the above technical solution, the extrusion block is fixed to the bottom of the transmission block, the inner wall of the extrusion block is in contact with the outer wall of the protrusion, one side of the transmission spring is fixed to the inner wall of the stabilizing column, and the other side of the transmission spring is fixed to the outer wall of the transmission block. When the stabilizing column moves downward, it can drive the transmission block to move downward, thereby causing the end of the transmission block to move on the wave plate. With the cooperation of the transmission spring, the transmission block can move back and forth in the stabilizing column, so that the inner side of the extrusion block can squeeze the protrusion to make arc-shaped movement, and the protrusion drives the rotating column to rotate.

[0010] According to the above technical solution, the protective device includes an inclined block, a push block, a fixed block, a connecting spring, a fixed seat, a rotating shaft, a support rod, a torsion spring, a rotating block, a moving disk, a transmission wheel, a triangular block, a semi-circular block, a striking block, a reset spring, and a return spring; the inclined block is fixed to the outer wall of the output rod, the push block penetrates the outer wall of the fixed column and is slidably connected at the penetration point, the fixed block is fixed to the inner side of the fixed column, one side of the connecting spring is fixed to the outer wall of the push block, and the other side of the connecting spring is fixed to the side wall of the fixed block.

[0011] According to the above technical solution, the fixed seat is fixed to the outer wall of the fixed column, the rotating shaft passes through the fixed seat and is rotatably connected at the through point, the support rod is fixed to the outer wall of the rotating shaft, one side of the torsion spring is fixed to the inner side of the fixed seat, the other side of the torsion spring is fixed to the outer wall of the support rod, and the rotating block is fixed to the end point of the rotating shaft. When the output rod moves downward, it can cause the inclined block to press the inclined surface at the top of the push block. Thus, when the push block is subjected to the pressing force, it can move outward from the fixed column, thereby causing the protrusion of the push block to press the support rod to rotate and unfold.

[0012] According to the above technical solution, the movable disk is slidably installed on the outer wall of the fixed column. One side of the return spring is fixed to the inner side of the fixed column, and the other side of the return spring is fixed to the top of the movable disk. The transmission wheel is fixed to the bottom of the movable disk. The striking block passes through the movable disk and fits at the penetration point. The bottom of the striking block is slidably connected to the top of the fixed seat. The semicircular block is fixed to the side wall of the striking block. The triangular block is fixed to the top of the movable disk. One side of the return spring is fixed to the inner side of the movable disk, and the other side of the return spring fits against the outer wall of the striking block. When the support rod rotates, it can cause the rotating shaft to rotate, thereby causing the rotating block to press against the bottom of the transmission wheel, causing the transmission wheel to drive the movable disk to move upward. When the movable disk moves upward, the inclined surface of the triangular block can press against the semicircular block. With the cooperation of the return spring, the striking block can strike the outer wall of the fixed column back and forth.

[0013] According to the above technical solution, the auxiliary device includes a guide block, a first spring, a connecting plate, a connecting block, a square plate, an extension plate, a second spring, a connecting plate, and a long block; the guide block is slidably installed on the inner side of the support plate, one side of the first spring is fixed to the inner side of the support plate, the other side of the first spring is fixed to the side wall of the guide block, the connecting plate is fixed to the side wall of the guide block, the connecting block is fixed to the side wall of the connecting plate, the baffle is fixed to the side wall of the connecting block, and the side wall of the baffle is in contact with the outer wall of the support rod.

[0014] According to the above technical solution, the extension plate is slidably installed at the bottom of the support plate, one side of the second spring is fixed to the inner side of the support plate, and the other side of the second spring is fixed to the outer wall of the extension plate. The connecting plate passes through the side wall of the support plate and is slidably connected at the penetration point. The long block is fixed on the side of the connecting plate away from the connecting plate. When the support rod rotates and does not contact the square plate, the guide block can be moved into the support plate through the cooperation of the first spring, so that the connecting plate can drive the end of the long block to squeeze the inclined surface of the extension plate, so that the two sets of extension plates move away from each other.

[0015] This invention provides a portable computer data acquisition device. It has the following advantages: 1. This invention, by setting up a support device, enables the output rod to move downwards by activating an electric push rod, which in turn moves the stabilizing column downwards. This, in turn, moves the plug downwards, allowing the plug and stabilizing column to be inserted into the soil, improving the stability of the equipment and solving the problem of instability and shaking during use. Furthermore, as the stabilizing column moves downwards, the transmission block moves on the corrugated plate. Through the cooperation of the transmission spring, protrusion, and pressing block, the plug can rotate left and right during insertion into the soil, facilitating insertion. This solves the problem of excessive resistance and difficulty in plug insertion caused by compacted soil.

[0016] 2. This invention, by incorporating a protective device, allows the inclined block to move downwards when the output rod moves downwards. This causes the inclined surface of the inclined block to press against the inclined surface at the top of the push block, moving the push block outwards from the fixed column. The protruding part of the push block then presses against the inner side of the support rod, causing the support rod to unfold on the fixed seat. This solves the problem of the support rod bearing the weight on the ground and preventing damage from impacts when the equipment collapses or tilts. When the support rod rotates and unfolds, it drives the rotating shaft to rotate the rotating block upwards, pressing against the bottom of the moving disc and causing the moving disc to move upwards. Through the cooperation of the triangular block, semi-circular block, and return spring, the striking block repeatedly strikes the outer wall of the fixed column, knocking away dirt and other debris brought into the fixed column.

[0017] 3. This invention, through the installation of an auxiliary device, ensures that when the support rod is extended, it does not obstruct the square plate. Because the first spring is under tension, it can move the guide block into the support plate. Through the cooperation of the connecting plate and the connecting plate, the end of the long block can press against the inclined surface of the extension plate, causing the two sets of extension plates to unfold outwards at the bottom of the support plate. This also increases the contact area between the support plate and the ground, further improving the stability of the equipment. Furthermore, when the support rod is rotated to retract, it presses against the square plate. Through the cooperation of the connecting block, the connecting plate, the connecting plate, and the second spring, the two sets of extension plates can be reset, effectively blocking the through-hole at the bottom of the fixed column. This solves the problem of a large amount of moisture or liquid entering the fixed column when the equipment is not in use, preventing damage to the internal electric components.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-9 One embodiment of the present invention is: a portable computer data acquisition device, including a collector 1, a button 2 fixed on the front of the collector 1, an antenna 3 fixed on the top of the collector 1, the collector 1 is an AirVisual series, and the acquired data can be transmitted to a mobile phone or computer through the antenna 3 for easy viewing by staff, a fixing column 4 is detachably installed on the bottom of the collector 1, a support plate 5 is fixed on the bottom of the fixing column 4, and a support device to improve the stability of the device is provided inside the fixing column 4.

[0022] Specifically, the support device includes an electric push rod 61, an output rod 62, a stabilizing column 63, a rotating column 65, a plug 66, a wave plate 64, a transmission block 68, a protrusion 67, a pressing block 610, and a transmission spring 69. The electric push rod 61 is fixed to the inner wall of the fixed column 4, the output rod 62 is fixed to the bottom output end of the electric push rod 61, the stabilizing column 63 is fixed to the bottom of the output rod 62, the rotating column 65 is rotatably mounted on the inner wall of the stabilizing column 63, the plug 66 is fixed to the bottom of the rotating column 65, the wave plate 64 is fixed to the inner wall of the fixed column 4, the transmission block 68 passes through the stabilizing column 63 and is slidably connected at the penetration point, the protrusion 67 is fixed to the top of the rotating column 65, the pressing block 610 is fixed to the bottom of the transmission block 68, the inner wall of the pressing block 610 is in contact with the outer wall of the protrusion 67, one side of the transmission spring 69 is fixed to the inner wall of the stabilizing column 63, and the other side of the transmission spring 69 is fixed to the outer wall of the transmission block 68.

[0023] The sidewall of the wave plate 64 has a wave-like convex and concave shape, so that when the transmission block 68 moves on the sidewall of the wave plate 64, it can move back and forth. By activating the electric push rod 61, the output rod 62 can be driven to move downward, which in turn drives the stabilizing column 63 to move downward. This causes the stabilizing column 63 to drive the plug 66 downward, so that the plug 66 and the stabilizing column 63 are partially inserted into the soil, improving the stability of the equipment and solving the problem of instability and shaking during use. Furthermore, when the stabilizing column 63 moves downward, it causes the transmission block 68 to move on the wave plate 64. Through the cooperation of the transmission spring 69, the protrusion 67 and the pressing block 610, the plug 66 can rotate back and forth left and right during the process of being inserted into the soil, thus making it easier for the plug 66 to be inserted into the soil. This solves the problem that the soil is too compact, resulting in excessive resistance and making it inconvenient to insert the plug 66.

[0024] In operation of this embodiment: When the device is used in an outdoor park, it can be placed on the muddy ground of the park. Then, by activating the electric push rod 61, the output rod 62 can be moved downward, thereby causing the output rod 62 to drive the stabilizing column 63 downward, which in turn causes the stabilizing column 63 to drive the rotating column 65 and the plug 66 downward, so that the plug 66 and the stabilizing column 63 can be inserted into the mud to stabilize the device. Furthermore, when the stabilizing column 63 moves downward, it drives the transmission block 68 to move downward, causing the transmission block 68 to move along the side wall of the corrugated plate 64. When the transmission block 68 presses against the protrusion of the side wall of the corrugated plate 64, it will be squeezed and move into the stabilizing column 63, causing the transmission spring 69 to stretch. When the transmission block 68 moves to the concave part of the side wall of the corrugated plate 64, it will no longer be squeezed. Because the transmission spring 69 is in a stretched state, it can drive the transmission block 68 to return to its original position. When the transmission block 68 moves into the stabilizing column 63, it can cause the inner side of the pressing block 610 to move against the protrusion 67 on the top of the rotating column 65. Because the protrusion 67 is fixed eccentrically on the top of the rotating column 65... When the inner side of the pressing block 610 presses the protrusion 67, the protrusion 67 is subjected to the pressing force and can rotate in the stabilizing column 63, thereby causing the protrusion 67 to drive the rotating column 65 to rotate. When the transmission spring 69 drives the transmission block 68 to reset, the inner side of the pressing block 610 at the bottom of the transmission block 68 can reset the protrusion 67, thereby causing the plug 66 to rotate back and forth when it is inserted into the soil. When the equipment is not in use, the electric push rod 61 can be controlled to drive the output rod 62 to move upward, so that the stabilizing column 63 extends into the fixed column 4, preventing the stabilizing column 63 and the plug 66 from protruding outside the fixed column 4, which would be inconvenient for the staff to carry.

[0025] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the outer wall of the fixed column 4 is provided with a protective device to prevent the equipment from collapsing, and the support plate 5 is provided with an auxiliary device. The protective device includes an inclined block 71, a push block 72, a fixed block 74, a connecting spring 73, a fixed seat 75, a rotating shaft 76, a support rod 78, a torsion spring 77, a rotating block 79, a moving disk 710, a transmission wheel 711, a triangular block 715, a semi-circular block 714, a striking block 712, a reset spring 716, and a return spring 713. The inclined block 71 is fixed to the outer wall of the output rod 62, the push block 72 penetrates the outer wall of the fixed column 4 and is slidably connected at the penetration point, the fixed block 74 is fixed to the inner side of the fixed column 4, one side of the connecting spring 73 is fixed to the outer wall of the push block 72, the other side of the connecting spring 73 is fixed to the side wall of the fixed block 74, the fixed seat 75 is fixed to the outer wall of the fixed column 4, and the rotating shaft 76 penetrates the fixed seat 75. The through-hole is rotatably connected, the support rod 78 is fixed to the outer wall of the rotating shaft 76, one side of the torsion spring 77 is fixed to the inner side of the fixed seat 75, and the other side of the torsion spring 77 is fixed to the outer wall of the support rod 78. The rotating block 79 is fixed to the end point of the rotating shaft 76. The moving disk 710 is slidably mounted on the outer wall of the fixed column 4. One side of the return spring 713 is fixed to the inner side of the fixed column 4, and the other side of the return spring 713 is fixed to the top of the moving disk 710. The transmission wheel 711 is fixed to the bottom of the moving disk 710. The striking block 712 passes through the moving disk 710 and fits at the through-hole. The bottom of the striking block 712 is slidably connected to the top of the fixed seat 75. The semi-circular block 714 is fixed to the side wall of the striking block 712. The triangular block 715 is fixed to the top of the moving disk 710. One side of the return spring 716 is fixed to the inner side of the moving disk 710, and the other side of the return spring 716 fits against the outer wall of the striking block 712.

[0026] The support rods 78 are arranged in three sets, and the three sets of support rods 78 are arranged in a circular array with the center point of the fixed column 4 as the center. When the output rod 62 moves downward, it can drive the inclined block 71 to move downward, so that the inclined surface of the inclined block 71 presses against the inclined surface at the top of the push block 72 to move, so that the push block 72 can move outward from the fixed column 4, so that the protruding part of the push block 72 presses against the inner side of the support rod 78, and the support rod 78 unfolds on the fixed seat 75. This solves the problem that when the equipment collapses and tilts, the support rod 78 will be supported on the ground, preventing the equipment from collapsing to the ground and being damaged by impact. When the support rod 78 rotates and unfolds, the spring force coefficient of the torsion spring 77 is five times that of the return spring 716 and the return spring 713. This causes the rotating shaft 76 to rotate the rotating block 79 upward, which in turn presses the bottom of the moving disk 710, causing the moving disk 710 to move upward. Through the cooperation of the triangular block 715, the semi-circular block 714 and the return spring 713, the striking block 712 can strike the outer wall of the fixed column 4 back and forth, which can knock off the soil and other debris brought into the fixed column 4 by the stabilizing column 63.

[0027] The auxiliary device includes a guide block 81, a first spring 82, a connecting plate 83, a connecting block 84, a square plate 85, an extension plate 88, a second spring 89, a connecting plate 86, and a long block 87. The guide block 81 is slidably installed on the inner side of the support plate 5. One side of the first spring 82 is fixed to the inner side of the support plate 5, and the other side of the first spring 82 is fixed to the side wall of the guide block 81. The connecting plate 83 is fixed to the side wall of the guide block 81. The connecting block 84 is fixed to the side wall of the connecting plate 83. The baffle is fixed to the side wall of the connecting block 84, and the side wall of the baffle is in contact with the outer wall of the support rod 78. The extension plate 88 is slidably installed at the bottom of the support plate 5. One side of the second spring 89 is fixed to the inner side of the support plate 5, and the other side of the second spring 89 is fixed to the outer wall of the extension plate 88. The connecting plate 86 passes through the side wall of the support plate 5 and is slidably connected at the point of penetration. The long block 87 is fixed on the side of the connecting plate 86 away from the connecting plate 83.

[0028] Two sets of extension plates 88 are provided, and the two sets of extension plates 88 are symmetrically arranged with the center line of the vertical direction of the support plate 5 as the axis of symmetry. When the support rod 78 is unfolded, the support rod 78 does not block the square plate 85. Because the first spring 82 is in a stretched state, it can drive the guide block 81 to move into the support plate 5. Through the cooperation of the connecting plate 83 and the connecting plate 86, the end of the long block 87 can be squeezed against the inclined surface of the extension plate 88, so that the two sets of extension plates 88 unfold outward at the bottom of the support plate 5, and can support the contact range of the plate 5 with the ground, further improving the stability of the equipment. Furthermore, when the support rod 78 rotates to retract, because the spring force coefficient of the torsion spring 77 is five times that of the first spring 82, the support rod 78 will compress the square plate 85. Through the cooperation of the connecting block 84, connecting plate 83, connecting plate 86 and the second spring 89, the two sets of extension plates 88 can be reset, which can block the through hole at the bottom of the fixed column 4. This solves the problem that when the equipment is not in use, a large amount of moisture or liquid will enter the fixed column 4, causing damage to the internal electric equipment.

[0029] In this embodiment, when the output rod 62 moves downward, it drives the inclined block 71 downward, causing the inclined surface of the inclined block 71 to press against the top inclined surface of the push block 72. When the inclined surface of the push block 72 is subjected to pressure, it moves outward from the fixed post 4, compressing the connecting spring 73. This causes the push block 72 to press against the outer wall of the support rod 78, causing the support rod 78 to rotate. This compresses and deforms the torsion spring 77, unfolding the three sets of support rods 78. When the support rods 78 unfold, they drive the rotating shaft 76 to rotate, causing the two ends of the rotating shaft 76 to drive the rotating block 79 to rotate upward. This causes the rotating block 79 to act as a transmission... The bottom of the wheel 711 is squeezed, causing the transmission wheel 711 to move upward, which in turn causes the moving disk 710 to move upward, compressing the return spring 713. When the moving disk 710 moves upward, the inclined surface of the triangular block 715 will squeeze the arc surface of the semicircular block 714, causing the semicircular block 714 to move towards the fixed post 4 under the pressure, which will drive the striking block 712 to move, compressing the return spring 716, so that the striking block 712 can strike the outer wall of the fixed post 4. When the triangular block 715 moves to a position where it does not squeeze the semicircular block 714, the return spring 716 is in a compressed state, which allows the return spring 716 to squeeze the striking block 712 to return to its original position. When the support rod 78 is extended, it prevents the square plate 85 from being compressed. Because the first spring 82 is under tension, the guide block 81 can move into the support plate 5. When the guide block 81 moves, it drives the connecting plate 83 to move into the support plate 5, which in turn drives the connecting plate 86 to move into the support plate 5. This causes the end of the long block 87 to press against the inclined surface of the extension plate 88, moving the two sets of extension plates 88 away from each other and allowing the extension plates 88 to extend out of the support plate 5. The spring force coefficient of the first spring 82 is five times that of the second spring 89, so when the extension plate 88 moves out of the support plate 5, it compresses the second spring 89. When the stabilizing column 63 extends into the fixed column 4, it causes the inclined block 71 to move upwards. The reset mechanism prevents the inclined block 71 from pressing the push block 72. Because the connecting spring 73 is in a compressed state, it can drive the push block 72 to reset and prevent it from pressing the support rod 78. Because the torsion spring 77 is in a compressed state, it can drive the support rod 78 to rotate and retract towards the fixed column 4, causing the support rod 78 to press the square plate 85 and move it closer to the fixed column 4. This causes the connecting block 84 to move, and the connecting plate 83 to move the guide block 81 outward from the support plate 5. This stretches the first spring 82 and causes the connecting plate 86 to drive the long block 87 to stop pressing the inclined surface of the extension plate 88. Because the second spring 89 is in a compressed state, it drives the two sets of extension plates 88 to move closer to each other, allowing the extension plates 88 to block the through hole at the bottom of the fixed column 4.
