Description

Technical Field

[0001] The utility model relates to the field of computer control equipment testing, in particular to a remote diagnosis device for computer control equipment. Background Art

[0002] Computer-controlled equipment refers to devices or systems that use computer technology to automatically control, monitor, and manage other equipment or systems. They are widely used in industries such as industry, transportation, medical care, and home. Their core is to achieve logical operations, data processing, and signal control through computers (such as microcontrollers, single-chip microcomputers, PLCs, industrial PCs, etc.).

[0003] As an indispensable wireless router in the home and office environment, it is also a type of computer-controlled device. It integrates computer technology, network communication technology and control functions, and has core capabilities such as data processing, network management and device control. During use, if the device frequently disconnects or the speed is abnormal, it is necessary to detect the wireless signal through a remote diagnostic device. The remote diagnostic device can detect the surrounding Wi-Fi signal strength, channel occupancy, and interference sources, and based on this, the wireless network can be diagnosed.

[0004] However, during the use of existing remote diagnostic devices, the antenna on the top for detecting signals usually needs to be manually adjusted by the operator. Manual direct rotation of the antenna is likely to cause the rotation amplitude to be too large, and the operation of manually rotating the antenna each time is difficult to completely repeat. Even if the same operator performs the same test at different times, the antenna's rotation angle, speed and other parameters may be inconsistent due to differences in hand strength, operating habits and other factors. This makes it difficult to obtain accurate and reliable repeatable results when conducting multiple tests to verify the results or compare test data under different conditions, thereby affecting the efficiency of diagnosis.

DETAILED DESCRIPTION

[0025] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figure 1-Figure 7 , the utility model provides a technical solution: a computer-controlled device test, comprising a body 1, an inner cavity of the body 1 is respectively installed with an interactive board 5 and a display screen 6, and an adjustment mechanism 2 is installed on the top of the back side of the body 1;

[0027] The adjusting mechanism 2 includes an adjusting box 201, the front side of the adjusting box 201 is fixedly connected to the back side of the body 1, the bottom of the back side of the adjusting box 201 is rotatably connected to the rotating wheel 202, the front side of the rotating wheel 202 is fixedly connected to the rotating rod 207, the surface of the rotating rod 207 is fixedly connected to the first sprocket 213, the surface of the first sprocket 213 is meshedly connected to the chain 216, the top of the inner cavity of the chain 216 is meshedly connected to the second sprocket 212, the inner cavity of the second sprocket 212 is fixedly connected to the adjusting rod 206, the surface of the adjusting rod 206 is rotatably connected to the positioning seat 203, the bottom of the positioning seat 203 is fixedly connected to the top of the body 1, the surface of the adjusting rod 206 is fixedly installed with the detection antenna 204, the detection antenna 204 The surface is rotatably connected to the inner cavity of the positioning seat 203. Through the setting of the rotating wheel 202, the rotating rod 207 can be driven to rotate. The rotation of the rotating rod 207 can drive the first sprocket 213 to rotate. The rotation of the first sprocket 213 can drive the chain 216 to rotate. The rotation of the chain 216 can drive the adjusting rod 206 to rotate. The rotation of the adjusting rod 206 can drive the detection antenna 204 to rotate. The transmission between the first sprocket 213 and the second sprocket 212 can improve the stability of the detection antenna 204 during rotation, ensure that the detection antenna 204 is in a state of uniform rotation, and avoid the detection antenna 204 rotating too fast, which affects the accuracy of angle adjustment.

[0028] As a further limitation of the adjustment mechanism 2 of the present invention, a movable groove 208 is provided on the top of the adjustment box 201, and a scale plate 205 is fixedly connected to the top of the adjustment box 201. The surface of the scale plate 205 is slidably connected to the inner cavity of the movable groove 208. The surface of the adjustment rod 206 is fixedly connected to a pointing plate 211. The front side of the pointing plate 211 is slidably connected to the back side of the scale plate 205. The pointing plate 211 is used in conjunction with the scale plate 205. Through the setting of the pointing plate 211, the adjustment rod 206 can rotate synchronously during the rotation process, so that the pointing plate 211 can be at the same angle as the detection antenna 204. Through the setting of the scale plate 205, the current angle of the pointing plate 211 can be compared, and then in the subsequent repeated detection process, the detection direction can be guaranteed to be consistent. After the subsequent detection is completed, it is convenient to make corresponding adjustments to the antenna of the computer-controlled device according to the detection results to ensure effective resolution of the problem after diagnosis.

[0029] The surface of the adjusting rod 206 is fixedly connected to the ratchet 214, and both sides of the inner cavity of the adjusting box 201 are fixedly connected to the support rod 217. The surface of the support rod 217 is rotatably connected to the pawl 220. One side of the pawl 220 is meshed with the surface of the ratchet 214. The front and back sides of the pawl 220 are rotatably connected to the limiting ring 215. The inner cavity of the limiting ring 215 is fixedly connected to the surface of the support rod 217. One side of the pawl 220 is fixedly connected to the spring 219. One end of the spring 219 is fixedly connected to the limiting plate 218. One side of the limiting plate 218 contacts the surface of the pawl 220. The surface of the limiting plate 218 is fixedly connected to the inner cavity of the adjusting box 201. Through the setting of the support rod 217, the ratchet 220 is engaged with the surface of the ratchet 214. The front and back sides of the pawl 220 are rotatably connected to the limiting ring 215. The inner cavity of the limiting ring 215 is fixedly connected to the surface of the support rod 217. The position of the pawl 220 is supported so that the pawl 220 can rotate on the surface of the support rod 217. The position of the pawl 220 is limited by the setting of the limit ring 215 to prevent the pawl 220 from detaching from the surface of the support rod 217 during rotation. The position of the pawl 220 is positioned by the setting of the spring 219. When the pawl 220 is not under force, the spring 219 restores the deformation to drive the pawl 220 to reset, ensuring the normal use of the pawl 220. The position of the pawl 220 is blocked by the setting of the limit plate 218 to prevent the pawl 220 from rotating in both directions, thereby causing the pawl 220 to be unable to effectively limit the rotation of the ratchet 214.

[0030] A rotating groove 210 is provided on both sides of the regulating box 201, and the inner cavity of the rotating groove 210 is rotatably connected to a rotating plate 209, and one side of the rotating plate 209 is fixedly connected to the surface of the pawl 220. Through the setting of the rotating groove 210, the surface of the rotating plate 209 can be rotated inside the regulating box 201, and then the rotation of the rotating plate 209 can drive the pawl 220 to rotate, disengaging the pawl 220 from the surface of the ratchet 214, canceling the meshing state of the pawl 220 and the ratchet 214, so that the rotating rod 207 can rotate normally.

[0031] The specific implementation of this embodiment is as follows: before adjusting the angle of the detection antenna 204, according to the direction to be adjusted, the rotating plate 209 is pushed in the corresponding direction to rotate, and the rotation of the rotating plate 209 drives the pawl 220 to rotate, and the rotation of the pawl 220 causes it to disengage from the surface of the ratchet 214. At this time, the ratchet 214 can rotate in one direction, and then the rotating wheel 202 is rotated by holding it, and the rotation of the rotating wheel 202 drives the rotating rod 207 to rotate, and the rotation of the rotating rod 207 drives the first sprocket 213 to rotate, and the rotation of the first sprocket 213 drives the chain 216 to rotate, and the rotation of the chain 216 drives the second sprocket 212 to rotate, and the rotation of the second sprocket 212 drives the second sprocket 212 to rotate. The adjusting rod 206 is driven to rotate, and the detection antenna 204 is driven to rotate by the rotation of the adjusting rod 206, so that the angle of the detection antenna 204 can be adjusted. When the rotating rod 207 rotates, the ratchet 214 is driven to rotate. During the rotation of the ratchet 214, it is in a meshing state with the surface of another pawl 220. The rotation of the ratchet 214 is positioned by the pawl 220, thereby improving the stability of the detection antenna 204 during the rotation. In addition, during the rotation of the adjusting rod 206, the pointing plate 211 is driven to rotate synchronously. By comparing the pointing direction of the pointing plate 211 during the rotation with the scale on the surface of the scale plate 205, the specific angle of the detection antenna 204 after adjustment can be confirmed, thereby facilitating repeated testing of the wireless network, thereby improving the efficiency of diagnosis.

[0032] Example 2: Please refer to Figure 1-Figure 3, the utility model provides a technical solution: a computer control equipment test, the utility model makes corresponding improvements to the technical problems mentioned in the background technology, a protective mechanism 3 is installed on the top of both sides of the body 1, the protective mechanism 3 includes a first fixing plate 303 and a second fixing plate 306, the bottom of the first fixing plate 303 is fixedly connected to the top of the body 1, one side of the second fixing plate 306 is fixedly connected to the surface of the body 1, the surfaces of the first fixing plate 303 and the second fixing plate 306 are fixedly connected to the guide rod 302, one end of one guide rod 302 is fixedly connected to the surface of the adjustment box 201, the surface of the guide rod 302 is slidably connected to a movable seat 305, the movable seat 305 is made of rubber, and one side of the movable seat 305 is fixedly connected to a protective cover 30 1. The inner cavity of the protective sleeve 301 is sleeved on the surface of the detection antenna 204. The first fixing plate 303 and the second fixing plate 306 are respectively provided to support the two ends of the guide rod 302 to ensure the stability of the guide rod 302 during use. The movable seat 305 is provided to slide on the surface of the guide rod 302, and then the movement of the movable seat 305 can drive the protective sleeve 301 to move along the path of the guide rod 302, thereby avoiding the position of the protective sleeve 301 from shifting during the movement process. At the same time, the provision of the protective sleeve 301 protects the surface of the detection antenna 204, thereby avoiding the detection antenna 204 from colliding with external objects when not in use, thereby causing damage to the detection antenna 204 and affecting subsequent normal use.

[0033] As a further limitation of the protective mechanism 3 of the present invention, protective pads 304 are fixedly connected to both sides of the top of the body 1. The protective pads 304 are made of rubber. The top of the protective pads 304 contacts the surface of the detection antenna 204. Through the setting of the protective pads 304, when the detection antenna 204 rotates from a vertical state to a horizontal state, the surface of the detection antenna 204 is protected, avoiding direct contact between the surface of the detection antenna 204 and the top of the body 1, preventing the detection antenna 204 from continuing to rotate after being in contact with the surface of the body 1, causing wear on the surface of the detection antenna 204 and the body 1.

[0034] The specific implementation of this embodiment is as follows: when the detection antenna 204 is not in use, the detection antenna 204 is rotated from a vertical state to a horizontal state, so that the surface of the detection antenna 204 is attached to the top of the protective pad 304, and the protective cover 301 is held and moved. The movement of the protective cover 301 drives the movable seat 305 to slide on the surface of the guide rod 302, so that the protective cover 301 moves along the path of the guide rod 302 until the inner cavity of the protective cover 301 is sheathed on the surface of the detection antenna 204. The surface of the detection antenna 204 can be protected by the protective cover 301, so as to prevent the detection antenna 204 from colliding with external objects when not in use, thereby causing damage to the detection antenna 204 and affecting subsequent normal use. At the same time, the movable seat 305 made of rubber can maintain a stable fixing effect without human interference, so as to prevent the position of the protective cover 301 from shifting during use, thereby affecting the protective effect of the detection antenna 204.

[0035] Example 3: Please refer to Figure 1 The utility model provides a technical solution: a computer-controlled equipment test. The utility model makes corresponding improvements to the technical problems mentioned in the background technology. The bottom of the surface of the body 1 is fixedly connected with an anti-slip cover 4, and the anti-slip cover 4 is made of silicone. The surface of the anti-slip cover 4 is provided with anti-slip grooves 7. The number of the anti-slip grooves 7 is several and they are arranged in multiple rows. Through the setting of the anti-slip cover 4, the friction force when in contact with the hand is increased. At the same time, through the setting of the anti-slip grooves 7, the roughness of the surface of the anti-slip cover 4 is further increased, so that more tiny protrusions and depressions are formed on the contact surface, thereby greatly improving the friction force.

[0036] The specific implementation of this embodiment is as follows: when the operator's hand contacts the surface of the anti-slip cover 4 while using the device 1, the anti-slip cover 4, made of silicone, increases friction during contact with the hand. Furthermore, the anti-slip grooves 7 increase the surface roughness of the anti-slip cover 4, creating more tiny bumps and depressions on the contact surface. When an external force acts, the anti-slip cover mechanically engages with the hand, creating a "locking" effect, significantly increasing friction. This prevents the hand from slipping while holding the device 1 and moving it, preventing the device 1 from falling to the ground and causing damage to the device 1.

[0037] It should be noted that parts have a life cycle and can be replaced during regular maintenance if they fail to meet their performance requirements. The deterioration of the performance of parts due to long-term use does not constitute a design defect in this application.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
